This application claims priority to Chinese Patent Application No. 202311284390.5, titled “CONVEYING DEVICE FOR PACKING MACHINE AND PACKING MACHINE”, filed on Sep. 28, 2023 with the China National Intellectual Property Administration, and to Chinese Patent Application No. 202311284465.X, titled “PACKING BAG OPERATION MODULE FOR PACKING MACHINE”, filed on Sep. 28, 2023 with the China National Intellectual Property Administration, which are incorporated herein by reference in its entirety.
The present application relates to a technical field of packing equipment, and in particular to a conveying module and a conveying device for a packing machine.
A packaging machine usually stacks and places several bags of raw materials in the bag storage unit of equipment, and then uses the bag taking mechanism to automatically take out the bags one by one from the bag storage unit, and then performs operations of opening the bag, charging, sealing the bag and discharging sequentially, ultimately getting the finished bag filled with materials and sealed. The existing automatic bag filling and sealing machine includes a variety of structural forms, but usually is of the circulating conveyor structure with a single station, i.e., can perform the opening, charging, sealing and discharging operations sequentially only for a single bag at one time, resulting in a low efficiency. In the prior art there is also a packaging machine which operates a number of bags simultaneously but has a serial type circulating conveyor mechanism, that is, several stations are provided in a group along the direction of conveying path of the circulating conveyor mechanism. Specifically, offline mechanisms such as bag loading mechanism, bag opening mechanism, charging mechanism, sealing mechanism and discharging mechanism are arranged in turn along the conveying direction of the circulating conveyor mechanism, and these offline mechanisms each include multiple processing stations arranged along the conveying direction of the circulating conveyor mechanism. With this structure, the packaging processing of multiple bags may be theoretically performed at the same time, but it will result in an overlong overall return travel, a complex structure, an excessive footprint of the circulating conveyor mechanism, and each bag actually needs to travel across the travel length covered by a plurality of stations in order to travel to the next offline mechanism to carry out the next packaging processing operation. It will lead to a relatively large proportion of the traveling time. Therefore, the efficiency is actually low, and it is impossible to realize efficient and stable packaging production.
The technical problem to be solved and the proposed technical task of the present application are to improve the existing technology to provide conveying module and a conveying device for a packaging machine, which may solve the problem of a complicated structure, a large footprint and/or difficulty in realizing efficient and stable packaging production occurred in the packaging machine in the prior art.
In order to solve the above problem, the present application provides the following solutions.
A conveying module for a packing machine includes a modular pedestal. A telescopic linkage mechanism and at least two holding units are provided on the modular pedestal, the holding units being arranged in parallel for placing packing bags. Each holding unit includes a left holding component and a right holding component which are configured to be engaged with sides of the packing bag respectively and are movable relative to each other. The telescopic linkage mechanism is configured to enable the left holding components and the right holding components to move relative to each other, so as to drive all the holding units to synchronously switch between a bag deployed attitude and a bag retracted attitude, and a spacing distance between the left holding component and the right holding component in the bag deployed attitude is larger than that in the bag retracted attitude. The conveying module for the packing machine according to the present application is provided with multiple holding units arranged in parallel, and simultaneously carries out various packaging processing operations for multiple packing bags in the parallel state, effectively improving the overall packaging processing efficiency. Compared with the existing series multi-station packaging processing, the present application adopts the parallel multi-station packaging processing. The holding units on the conveying module for the packing machine of the present application are not arranged in the conveying direction of the circulating conveyor mechanism. Increasing the number of the holding units arranged in parallel in the conveying module for the packing machine may not result in an increase in the length of the loop stroke of the circulating conveyor mechanism of the packing machine, that is, the circulating conveyor mechanism is able to maintain a relatively short length of the loop stroke, so as to increase the number of parallel processing and keep the structure of the equipment compact. The volume of the overall equipment may not be increased excessively, and the operation efficiency is higher. The dynamic and static time ratio is more reasonable when packaging processing, better improving the production efficiency and realizing the efficient and stable packaging production. Furthermore, the holding units on the conveying module for the packing machine of the present application are driven by the telescopic linkage mechanism to act synchronously. The structure is highly integrated, more compact, and reduces the occupied volume. When the holding unit is in the bag deployed attitude, the packing bag is straightened and flattened; and when the holding unit is in the bag retracted attitude, the both sides of the packing bag are close to each other to allow the packing bag to be in a loosened state, thereby facilitating opening the mouth of the packing bag. The packaging processing operations such as bag loading, filling and sealing have different requirements on the attitude of the packing bag. All the holding units are driven by the telescopic linkage mechanism to switch synchronously the attitudes, ensuring the stability and quality of various packaging processing operations.
Further, a bag width adjusting mechanism is provided on the modular pedestal, and is associated with at least one of the left holding component and the right holding component to synchronously adjust the spacing distance between the left holding component and the right holding component of each holding unit to adapt to packing bags of different sizes. Only a small adjustment of the spacing distance of jig for clamping the both sides of the packing bag is needed to achieve the bag deployed and retracted actions required for packing processing, so that the packing bag is straightened or in the loosened state. The existing packaging machine is usually only applicable to a single size of the packing bag. When the size of the packing bag changes, the traditional packing machine cannot make the packing bag with changed size straight or in the loosened state, since it can perform a small change of the spacing distance of the jig only for a single size of the packing bag to achieve the bag deployed and retracted actions and thus cannot meet the requirement of packing processing. The conveying module for the packing machine of the present application can use the telescopic linkage mechanism to synchronously adjust the spacing distance between the left and right holding components to carry out the bag deployed and retracted actions, and can use the bag width adjusting mechanism to substantially adjust the spacing distance between the left and right holding components to adapt to the packing bags of different sizes, and the bag width adjusting mechanism does not hinder the action of the telescopic linkage mechanism. That is, after the bag width adjusting mechanism performs the bag width adjustment, the telescopic linkage mechanism still can adjust reliably and normally the spacing distance between the left and right holding components in a small range, which ensures stable and reliable packaging processing while matching the packing bags of different sizes.
Further, the bag width adjusting mechanism is associated with the telescopic linkage mechanism, and is associated with at least one of the left holding component and the right holding component via the telescopic linkage mechanism. The structure is more compact and simplified. The telescopic linkage mechanism is an adjusting mechanism for adjusting the spacing distance between the left holding component and the right holding component. The bag width adjusting mechanism is associated with the telescopic linkage mechanism, and then adjusts the state of the telescopic linkage mechanism, thereby indirectly adjusting the spacing distance between the left and right holding components via the telescopic linkage mechanism so as to adapt to the packing bags of different sizes. The bag width adjusting mechanism is appropriately combined with the telescopic linkage mechanism, and does not need too many linkage structures to be associated with at least one of the left and right holding components. The structure is more compact and simplified, is implemented more conveniently, and has a low cost.
Further, the bag width adjusting mechanism includes a limiting member and an elastic member. The limiting member is adjustably connected to the modular pedestal of the conveying module for the packing machine, and the elastic member is configured to act on a telescopic control member of the telescopic linkage mechanism to enable the telescopic control member to elastically abut against the limiting member. The bag width adjusting mechanism limits the telescopic control member of the telescopic linkage mechanism only on a single side. When adjusting, the limiting member drives the telescopic control member to move, so that the telescopic linkage mechanism changes the spacing distance between the left and right holding components, thereby matching the packing bags of different sizes. And, the bag width adjusting mechanism also maintains an elastic space for movement of the telescopic control member of the telescopic linkage mechanism. The telescopic control member can overcome the elastic member to move under drive of the telescopic drive mechanism. That is, after carrying out the bag width adjustment, the telescopic linkage mechanism can make a small adjustment of the spacing distance between the left and right holding components under drive of the telescopic drive mechanism, so as to achieve the bag deployed and retracted actions, thereby performing normally the packing processing while matching the packing bags of different sizes.
Further, the telescopic linkage mechanism includes telescopic linkage bars and a telescopic control member, and the telescopic linkage bars extend and are arranged along a direction of arrangement of the holding units. Each telescopic linkage bar is associated with at least one of the left holding component and the right holding component, and the telescopic control member is drivingly connected to the telescopic linkage bar, so as to drive the telescopic linkage bar to rotates around its axis or move in its axial direction, thereby causing relative movement of the left holding component and the right holding component. The structure is simple and compact, and is easily carried out. The telescopic linkage bar can be associated with at least one of the left and right holding components in any connecting manner. When the telescopic linkage bar rotates or axially moves, it at least drives one of the left and right holding components to move for adjustment.
Further, each telescopic linkage bar is provided with a first threaded section and a second threaded section which are oppositely threaded, wherein the left holding component is mounted on the first threaded section, the right holding component is mounted on the second threaded section, the telescopic linkage bar is configured to rotate around its axis to enable opposite movements of the left holding component and the right holding component in an axial direction of the telescopic linkage bar; or
Further, the first linkage bar and the second linkage bar are connected through a reverse linkage mechanism such that, when one of the first linkage bar and second linkage bar moves axially, the other of the first linkage bar and second linkage bar is driven by the reverse linkage mechanism to move axially in a reverse direction. Only one of the first linkage bar and the second linkage bar is needed to drive, which is conducive to simplifying the telescopic drive mechanism. Only a single set of drive mechanism is needed, reducing the difficulty of the design and improving the compactness of the structure.
Further, the reverse linkage mechanism includes a first rack, a second rack and a first gear, wherein the first linkage bar is connected to the first rack, the second linkage bar is connected to the second rack, a length direction the first rack and the second rack is in accord with a direction of axis of the first linkage bar and the second linkage bar, the first rack and the second rack are space apart in parallel, the first gear is arranged between and meshed with the first rack and the second rack; or
Further, the telescopic control member includes a telescopic control rack and a telescopic control gear. The telescopic control rack is slidably arranged on the modular pedestal of the conveying module for the packing machine, and the telescopic control gear is rotatably arranged on the modular pedestal. The telescopic control rack and the telescopic control gear are meshed with each other, the telescopic control gear is drivingly connected to the telescopic linkage bar such as to drive the telescopic linkage bar to rotate around its axis or move in its axial direction. The telescopic control rack can be conveniently cooperated with the telescopic drive mechanism, no matter the telescopic drive mechanism adopts the power actuating mechanism or the guiding member, which can conveniently and reliably drive the telescopic control rack to move. The linear motion of the telescopic control rack is converted into a rotational motion of the telescopic control gear through the mehsingly connection between the telescopic control rack and the telescopic control gear, and the rotating telescopic control gear drives the telescopic linkage bar to move. The connection structure between the telescopic control gear and the telescopic linkage bar may be flexibly designed according to the required action mode of the telescopic linkage bar.
Further, a limiting member and an elastic member are further included. The limiting member is adjustably connected to the modular pedestal of the conveying module for the packing machine in a sliding direction of the telescopic control rack, and the elastic member is arranged between the telescopic control rack and the modular pedestal and enables the telescopic control rack to elastically abut against the limiting member. The limiting member limits the telescopic control member of the telescopic linkage mechanism on a single side. When adjusting, the limiting member drives the telescopic control member to move, so that the telescopic linkage mechanism changes the spacing distance between the left and right holding components, thereby matching the packing bags of different sizes. And, the telescopic control member of the telescopic linkage mechanism has an elastic space for movement. The telescopic control member can overcome the elastic member to move under drive of the telescopic drive mechanism. That is, after carrying out the bag width adjustment, the telescopic linkage mechanism can make a small adjustment of the spacing distance between the left and right holding components under drive of the telescopic drive mechanism, so as to achieve the bag deployed and retracted actions, thereby performing normally the packing processing while matching the packing bags of different sizes.
Further, the left holding component and the right holding component each are a jig. The packing bag is fixed by clamping, having a good fixed stability and ensuring that the packing bag is always in a controlled state during packaging processing to improve the reliability of packaging processing. A clamping linkage mechanism is provided on the conveying module for the packing machine, and the clamping linkage mechanism is configured to drive the left holding components and the right holding components of all of the holding units to synchronously switch between a jig opened state and a jig closed state. When loading a bag, the jig needs to switch to the jig opened state to receive the incoming packing bag, and then switch to the jig closed state to clamp stably the packing bag. When discharging, the jig needs to switch to the jig opened state to release the processed packing bag. The clamping linkage mechanism is integrated on the conveying module for the packing machine, which is highly integrated. The linkage structure is adopted, which is compact and occupies less space. The drive is more convenient, since only one drive mechanism is needed, reducing the design difficulty of the drive mechanism and occupied space and effectively ensuring the consistency of the action of the holding units. The clamping linkage mechanism includes clamping linkage bars extending and arranged along a direction of arrangement of the holding units. Each clamping linkage bar is provided thereon with an actuating part associated with the left holding component and the right holding component. The actuating part is configured to, when the clamping linkage bar rotates around its axis or moves axially, drive the left holding component and the right holding component to synchronously switch between the jig opened state and the jig closed state. The structure is simple, is easy to implement, and has a good compactness, small footprint, and high linkage reliability.
Further, a scraping mechanism is further provided on the modular pedestal. In the process of packaging processing, the following situations may occur: the packing bag is not placed on the holding unit; the packing bag falls off from the holding unit; material leaks when filling; etc. The packing bag and material falling in apparatuses of the packing machine may affect the normal operation of the packing machine packing bag, and the scraping mechanism arranged on the modular pedestal can scrape and clean the packing bag and material during traveling of the conveying module for the packing machine, ensuring cleanliness of equipment and achieving the centralized recycling and reuse of leaking materials.
Further, the scraping mechanism includes a stationary element and a sliding element, wherein the stationary element is connected to the modular pedestal, the sliding element is slidably connected to the stationary element;
The scraping mechanism is of a telescopic structure, realizing retraction and deployment. When the conveying module for the packing machine is in a preset positive attitude, the scraping mechanism is in a deployed state so as to reliably realize the function of cleaning and centralized recovery of leaking materials. When the conveying module for the packing machine is in a preset reverse attitude, the scraping mechanism is retracted to reduce the occupied space, avoiding the interference of the conveying module for the packing machine in the process of traveling. The structure is highly contact, which is conducive to improving the overall compactness of the packaging machine and reducing the volume of the equipment.
A conveying device for a packing machine includes the above conveying module for the packing machine, and a circulating conveyor mechanism, wherein the conveying module for the packing machine is provided on the circulating conveyor mechanism such as to be driven by the circulating conveyor mechanism to circularly travel, and a telescopic drive mechanism is provided beside the circulating conveyor mechanism and in configured to drive the telescopic linkage mechanism. The conveying device for the packing machine described in the present application has a compact structure and a small footprint, realizes multi-station parallel conveying to carry out multi-station parallel packaging processing, effectively improves the packaging processing efficiency, and realizes highly efficient and stable packaging production. The telescopic drive mechanism arranged beside the circulating conveyor mechanism enables all the holding units to synchronously act by driving the telescopic linkage mechanism. The compact structure and high degree of integration can reduce the difficulty and complexity of the design of the telescopic drive mechanism, making the telescopic drive mechanism more simplified, and ensuring that the packing bag placed on the conveying module for the packing machine can be deployed and retracted efficiently and consistently.
Further, the telescopic drive mechanism includes a power actuating mechanism, or a guiding member provided along a conveying path of the circulating conveyor mechanism, or combination thereof. The power actuating mechanism refers to a mechanism capable of carrying out an action, which may be driven by a motor, cylinder, etc. The power actuating mechanism actively moves to drive the telescopic linkage mechanism, which further drives the holding unit to synchronously switch between the bag deployed attitude and the bag retracted attitude. The power actuating mechanism may be moved linearly, rotated, swung, etc. The guiding member has a changed guide path. The conveying module for the packing machine moves under drive of the circulating conveyor mechanism. By designing the path, shape or structure of the guiding member, the telescopic linkage mechanism may be automatically driven to move during movement of the conveying module for the packing machine. The guiding member is a stationary part without the need for providing a power source, thereby saving energy and having a high drive reliability.
Further, the power actuating mechanism includes a toggle member and a power assembly, wherein the toggle member is adjustably connected to and driven by the power assembly;
The structure is simple and easy to implement. The toggle can reliably drive the telescopic linkage mechanism to carry out the action, but also does not hinder movement of the conveying module for the packing machine under drive of the circulating conveyor mechanism. And, the power actuating mechanism and the guiding member adopt an adjustable structure, and can be adjusted adaptively in conjunction with the telescopic linkage mechanism to increase the scope of application of the packaging machine.
Further, the circulating conveyor mechanism includes two guide rails which are arranged in parallel and each in a circular path. The conveying module for the packing machine is slidably connected to the guide rails. The conveying drive mechanism of the circulating conveyor mechanism drives the conveying module for the packing machine to travel along the guide rails intermittently. The structure is simple, has a good stability since the conveying module for the packing machine is carried by double guide rails stably, ensures the stability and precision of traveling of the conveying module for the packing machine, and thus ensures the stability and efficiency of the packaging processing.
Further, the modular pedestal includes two support plates spaced apart and slidably connected to the guide rails respectively. The telescopic linkage mechanism and the holding units arranged in parallel are disposed between the two support plates. The structure is simplified and compact. The direction of arranging the holding units in parallel is perpendicular to the direction of conveying the circulating conveyor mechanism, which is easy to dispose the holding units in parallel between the two support plates. The both ends of the conveying module for the packing machine are supported on the guide rails by the support plates for conveying and traveling. The holding units located between the support plates is in a hang state, and do not interfere with the circulating conveyor mechanism, facilitating various packaging processing operations
Further, each guide rail includes arc sections and straight sections. The support plate is provided with a sliding part engaged with the guide rail. The sliding part includes a first guide wheel and a second guide wheel. The guide rail is sandwiched between the first guide wheel and the second guide wheel. Two first guide wheel and two second guide wheel may be provided. When the sliding part is located at the arc section and the straight section of the guide rail, the first guide wheel and the second guide wheel are in rolling contact with the guide rail, ensuring the smoothness of conveying of the conveying module for the packing machine, i.e., traveling stably and rapidly at both the arc section and straight section. Therefore, the operating stability and efficiency of the packing machine can be ensured.
A packing machine includes the above conveying device for the packing machine, and several operating mechanisms for carrying out different packaging processing operations respectively. The operating mechanisms are respectively provided at various preset stations on the conveying path of the conveying device for the packing machine. Each operating mechanism includes operating units, the number of which corresponds to the number of the holding units of the conveying module for the packing machine, thereby realizing multi-station packaging processing, effectively improving the packaging processing efficiency, and realizing efficiently and stably packaging production.
Compared with the prior art, the present application has the following advantageous.
The conveying module and conveying device for the packing machine according to the present application adopt a parallel structure, which realizes multi-station parallel conveying to carry out multi-station parallel packaging processing, effectively improving the overall production efficiency of packaging processing without excessively increasing the occupied space. The structure is compact. The structure of the linkage control is adopted, facilitating control, having a high consistency of the action, being simple in the structure and easy to implement.
The technical solutions in the embodiments of the present application will be described clearly and completely in the following in conjunction with the embodiments of the present application. It is obvious that the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.
A conveying module for a packing machine, a conveying device for a packing machine, and a packing machine are disclosed in embodiments of the present application, which adopt parallel multi-station structure to increase the number of packaging processing per unit of time, thereby effectively improving the productivity of packaging processing and realizing efficient and stable packaging production.

In an embodiment, as shown in
The telescopic linkage mechanism includes telescopic linkage bars 2 and a telescopic control member. The telescopic linkage bars 2 extend and are arranged in a direction of arrangement of the holding units 1, and are associated with at least one of the left and right holding components 11, 12. The term “associated” refers to connection including direct connection, indirect connection, drive connection, etc. The telescopic control member is drivingly connected to the telescopic linkage bar 2, and cooperated with the telescopic drive mechanism 300. The telescopic control member is driven by the telescopic drive mechanism 300, and then drives the telescopic linkage bar 2 to rotate around its own axis or move in its own axial direction, so as to adjust the spacing distance between the left and right holding components 11, 12 and ultimately switch the packing bag between the straightened state and the loosened state.
In an embodiment as shown in
Further, the telescopic control member includes a telescopic control rack 41 and a telescopic control gear 42. The telescopic control rack 41 is slidably arranged on the modular pedestal 101 of the conveying module 100 for the packing machine, and the telescopic control gear 42 is rotatably arranged on the modular pedestal 101. The telescopic control rack 41 is meshingly engaged with the telescopic control gear 42, and cooperates with and driven by the telescopic drive mechanism 300. The telescopic control gear 42 is drivingly connected to the telescopic linkage bar 2 and drives the telescopic linkage bar 2 to rotate around its axis. In an embodiment, the telescopic control gear 42 is directly connected to the telescopic linkage bar 2, with the rotation axial direction of the telescopic control gear 42 being the axial direction of the telescopic linkage bar 2, and the sliding direction of the telescopic control rack 41 being perpendicular to the axial direction of the telescopic linkage bar 2. Preferably, the sliding direction of the telescopic control rack 41 is perpendicular to the conveying direction of the circulating conveyor mechanism 200, which facilitates arrangement of the telescopic drive mechanism. A control part is provided on the telescopic control rack 41 to cooperate with the telescopic drive mechanism which drives the telescopic control rack 41 to slide, which in turn drives the telescopic control gear 42 to rotate. As a result, the telescopic linkage bar 2 is rotated, so that the left and right holding components 11 and 12 move in opposite directions to adjust the spacing distance therebetween, i.e., switch the holding unit 1 between the bag deployed attitude and the bag retracted attitude. The structure is simple and easily achieved.
The cooperation between the telescopic drive mechanism and the telescopic linkage mechanism achieves switch between the bag deployed attitude and the bag retracted attitude of the holding unit 1. In other words, the cooperation between the telescopic drive mechanism and the telescopic linkage mechanism enables a small change of the spacing distance between the left and right holding components 11, 12, thereby only being suitable for the bag deploy action and bag retracted action of the packing bag of a single size. To widen the applicable scope of the packing machine which can be applied to the packing bag of various sizes, a bag width adjusting mechanism may be provided on the modular pedestal 101 of the conveying module 100 for the packing machine, and is associated with at least one of the left and right holding components 11, 12 to adjust synchronously the spacing distance between the left and right holding components 11, 12 of each holding unit 1 to match the packing bags of different sizes. The bag width adjusting mechanism is configured to adjust the spacing distance between the left and right holding components 11, 12 in a wide range to adapt to the packing bags of different sizes. The bag width adjusting mechanism does not hamper action of the telescopic linkage mechanism. That is, after the bag width adjustment of the bag width adjusting mechanism, the telescopic linkage mechanism still can adjust the spacing distance between the left and right holding components 11, 12 in a small range reliably and normally, thereby ensuring the stable and reliable packing processing while matching the packing bags of different sizes. For example, the original matching width of the packing bag is 10 cm, and the spacing distance between the left and right holding components is the bag deploy distance when it is 10 cm, and is the bag retracted distance when it is 8 cm. In other words, the telescopic linkage mechanism drives the left and right holding components to move with the spacing distance keeping in the range of 8 cm to 10 cm. When replacing with a packing bag with a width of 15 cm, the maximum spacing distance between the left and right holding components can only be 10 cm, and the packing bag with the width of 15 cm cannot be straightened, which seriously affects the packaging processing operations of bag loading and sealing. For the packing bag with the width of 15 cm, it is necessary to move the left and right holding components with the spacing distance in a range of 13 cm to 15 cm. Thus, the basic spacing distance between the left and right holding components needs to be adjusted, and then the telescopic linkage mechanism is used to drive the left and right holding components to switch attitudes.
In an embodiment as shown in
Further, the left and right holding components 11, 12 each may be a sucker or a jig, as long as the left and right holding components 11, 12 can be engaged stably with the sides of a packing bag respectively to keep the packing bag in a controlled state. The sucker sucks the side of the packing bag in a negative pressure adsorption way, whereas the jig clamps and fixes the side of the packing bag in a clamping way. For the sucker, grasping and releasing the packing bag are achieved by controlling on/off of the negative pressure. For the jig, grasping and releasing the packing bag are achieved by controlling opening/closing of the jig. In comparison, the jig structure is implemented more easily and has a lower cost. The jig is preferably an elastic jig, which can automatically and stably clamp and fix the packaging bag effectively. As shown in

Further, the support plate 1033 is provided with a sliding part engaged with the guide rail 201. The sliding part includes a first guide wheel 2021 and a second guide wheel 2022 between which the guide rail 201 is sandwiched. The guide rail 201 is provided with a guide groove on each side, and the first and second guide wheels 2021, 2022 are slidably received in the guide grooves, so as to ensure the precise and stable traveling of the conveying module 100 for the packing machine. Further, there are two first guide wheels 2021 spaced apart in the direction of path of the guide rail 201, and two second guide wheels 2022 spaced apart in the direction of path of the guide rail 201. The path of the guide rail 201 is oblong as a whole, that is, the guide rail 201 includes arc sections and straight sections. The first and second guide wheels 2021, 2022 are in rolling contact with the guide rail 201 when the sliding part is located at the arc sections and the straight sections of the guide rail 201. When the conveying module 100 for the packing machine travels to the arc section, the sliding part of the support plate 103 is engaged with the arc section of the guide rail 201, and the first and second guide wheels 2021, 2022 are in rolling contact with the arc section, ensuring the stability and smoothness when passing through the bending section. The plane where the conveying path of the circulating conveyor mechanism 200 is located is vertically oriented. The two straight sections of the guide rail 201 are parallel to the horizontal plane and are distributed in the up and down direction, and the ends of the two straight sections are connected through the respective arc sections. The conveying drive mechanism of the circulating conveyor mechanism 200 may be a chain drive mechanism, a synchronous belt drive mechanism, a magnetic levitation drive mechanism and so on.
Further, as shown in
For the packing machine, in the packaging processing operation of filling material, it is necessary to maintain the holding units 1 in the bag retracted attitude. In order to improve the production efficiency and optimize the static and dynamic ratio of the packaging machine, when there is more material to be filled and it takes a long time, the operation of filling material will be divided into multiple steps so that the conveying path covered by the material filling operation is long in length, and the guiding member 302 is more suitable for such an application. The telescopic drive mechanism may adopt one of the power actuating mechanism 301 and the guiding member 302, or combination of them, depending on the specific situation. When the power actuating mechanism 301 is combined with the guiding member 302, the power actuating mechanism 301 firstly drives the telescopic control member of the telescopic linkage mechanism to move, and then directs the telescopic control member into the guiding member 302, so that the telescopic control member of the telescopic linkage mechanism is guided and limited by the guiding member 302 in a long conveying path, and so that the holding units 1 is maintained in a desired attitude.
When the bag width adjusting mechanism is associated with at least one of the left and right holding components 11, 12 via the telescopic linkage mechanism, the bag width adjusting mechanism adjusts the state of the telescopic linkage mechanism, and then indirectly adjusts, via the telescopic linkage mechanism, the spacing distance between the left and right holding components 11, 12 to adapt to the packing bags of different sizes. After the bag width adjusting mechanism adjusts the state of the telescopic linkage mechanism to adapt to the packing bags of different sizes, the original position of the telescopic control member of the telescopic linkage mechanism is changed. It is necessary to adaptively adjust the telescopic drive mechanism to adapt to the telescopic control member in the new position, thereby matching the packing bags of different sizes while achieving normal telescopic adjustment. The toggle member 3011 is adjustably connected to and driven by the power assembly 3012. The position of the toggle member 3011 is adjusted to adapt to the positional change of the telescopic control member. In an embodiment, the toggle member 3011 includes hoop part 3013, and the power assembly 3012 includes a tie rod. The hoop part 3013 is adjustable connected to and surrounds the tie rod, which facilitates assembling or disassembling, a stable connection and a convenient adjustment. The height of the toggle member 3011 on the tie rod may be adjusted to precisely adapt to the positional change of the telescopic control member. For the guiding member 302, it may be adjustably disposed next to the circulating conveyor mechanism 200. The conveying device for the packing machine may be provided with a side plate (no shown) at the side of the circulating conveyor mechanism 200, and the side plate is configured to protect the interior components of the conveying device for the packing machine and also to ensure the aesthetics. The guiding member 302 may be adjustably mounted on the side plate. After bag width adjustment, it is convenient to adjust the height of the guiding member 302 to precisely adapt to the change of position of the telescopic control member. For the power actuating mechanism 301, the toggle member 3011 moves under drive of the power assembly 3012, so that the power assembly 3012 may directly adjust the moving range of the toggle member 3011 to adapt to the positional change of the telescopic control member after the bag width adjustment.

In an embodiment, the operating mechanisms include a bag loading mechanism 401, a bag opening mechanism 402, a filling mechanism 403, a sealing mechanism 404, a discharging mechanism 405, etc. Each operating mechanism includes operating units, the number of which corresponds to the number of the holding units 1 of the conveying module 100 for the packing machine, thereby efficiently realizing multi-station packaging processing and effectively improving the packaging processing efficiency. The bag loading mechanism 401 is configured to place the packing bag stored in the bag compartment onto the holding unit 1 of the conveying module 100 for the packing machine. The bag opening mechanism 402 is configured to open the mouth of the packing bag to prepare for subsequent filling. The filling mechanism 403 is configured to fill material into the packing bag. The sealing mechanism 404 is configured to seal the mouth of the packing bag. The discharging mechanism 405 is configured to receive the processed packing bag filled with material for discharging.
Further, the circulating conveyor mechanism 200 of the packing machine needs to carry out conveying action. The conveying module 100 for the packing machine needs to carry out the bag deployed and retracted actions and the camp opened and closed actions. The various operating mechanisms also need to carry out various packaging processing actions. The packing machine needs a power system to drive the various assemblies to carry out the actions. If the separate power drive mechanisms are adopted for the various assemblies respectively, when one of the power drive mechanism fails, it will affect adversely the operation of the entire packaging machine and even cause serious problems. Therefore, the packaging machine preferably adopts a linked power system. In an embodiment, a power system includes a total power source, power distribution mechanism and several cam drive mechanisms. The total power source may be a motor, an engine, etc. The power distribution mechanism is drivingly connected to the total power source to distribute the power of the total power source, and includes a continuous power output end for outputting power for continuous actions, and an intermittent power output end for outputting power for intermittent actions. The intermittent power output end is drivingly connected to the circulating conveyor mechanism 200, so that the circulating conveyor mechanism 200 drives the conveying module 100 for the packing machine to intermittent travel. The conveying module 100 for the packing machine is driven by the circulating conveyor mechanism 200 to move to and stop at the preset station for carrying out the packing processing operation by the operating mechanism. Then, the circulating conveyor mechanism 200 further drives the conveying module 100 for the packing machine to continuously move. The continuous power output end is drivingly connected to the various operating mechanisms through corresponding cam drive mechanisms. The various operating mechanisms are driven by the cam drive mechanisms, so as to carry out high-precision cooperation with the intermittent traveling conveying module 100 for the packing machine, ensuring the stability and accuracy of the packaging processing. Preferably, the cam drive mechanisms are connected in series to form a series transmission structure. In this way, when one transmission link fails, the entire power system will stop, effectively avoiding occurrence of interference or impact of the various moving mechanisms of the packing machine, and avoiding the expansion of accidental damage so as to facilitate rapid maintenance to resume production operations.
In the packaging process, if there is a mechanical failure or communication failure, leakage of materials may occur. That is, the following situations may occur: the packing bag is not placed onto the holding unit; the packing bag falls off from the holding unit; material is leaked out when filling material; etc. Occurrence of these situations may be caused by the conveying module for the packing machine not traveled in place, failure of the left and right holding components of the holding unit, the ineffectively opened mouth of the packing bag due to inadequate retracted attitude so that the material is difficult to be precisely and fully loaded in the packing bag, etc. the packing bag and material falling in apparatuses of the packing machine may affect the normal operation of the packing machine, resulting in damage to the apparatuses, contamination and so on. To clean up the fallen packing bag and material, as shown in
In a preferred embodiment as shown in
In a preferred embodiment, when the conveying module 100 for the packing machine is in a preset positive attitude, the sliding element 712 automatically slides relative to the stationary element 711 to be switched to a deployed state. When the conveying module 100 for the packing machine is in a preset reverse attitude, the sliding element 712 automatically slides relative to the stationary element 711 to be switched to a retracted state. In an embodiment, the conveying path of the circulating conveyor mechanism is oblong, and the plane where the conveying path is located is oriented vertically. The conveying path of the circulating conveyor mechanism includes arc sections and straight sections. The two straight sections are parallel to the horizontal plane and are distributed in the up and down direction, and the ends of the two straight sections are connected through the respective arc sections, so that the conveying module 100 for the packing machine annularly travels along a circular path. When the conveying module 100 for the packing machine is at the upper straight section, the conveying module 100 for the packing machine is in the preset positive attitude. When the conveying module 100 for the packing machine is at the lower straight section, the conveying module 100 for the packing machine is in a preset reverse attitude. The conveying module 100 for the packing machine in the reverse attitude is in an upside-down state relative to the conveying module 100 for the packing machine in the positive attitude. The sliding element 712 and the stationary element 711 of the scraping mechanism 71 are in a freely slidable state. When the conveying module 100 for the packing machine switches between the positive attitude and the reverse attitude, the sliding element 712 automatically slides relative to the stationary element 711 under the action of gravity to switch between the deployed state and the retracted state. When the conveying module 100 for the packing machine is in the preset positive attitude, the scraping mechanism automatically switches to the deployed stated under the action of gravity, and the sliding element 712 slides out of the stationary element 711, so that the sliding element 712 can effectively cooperate with the baffle 72 below the traveling path of the conveying module 100 for the packing machine, thereby reliably realizing the function of cleaning and the function of intensively collecting of the leaking material. Preferably, when the scraping mechanism 71 is in the deployed state, the sliding element 712 can be in contact with the upper surface of the baffle 72, so as to adequately clean and push the materials on the baffle 72. In an embodiment, the sliding element 712 may be provided with brushes to contact with the baffle 72, not only ensuring the adequacy of the cleaning, but also avoiding excessive friction resistance from generating due to contact between the sliding element 712 and the baffle 72 to hinder the normal traveling of the conveying module 100 for the packing machine. When the conveying module 100 for the packing machine is in a present reverse attitude, the scraping mechanism automatically switches to the retracted state under the action of gravity, and the sliding element 712 slides into the stationary element 711, reducing the occupied space, especially, facilitating reduction of the spacing distance between the two straight sections of the circulating conveyor mechanism. It is possible to avoid interference in the process of traveling of the conveying module for the packing machine, and the structure is highly compact, which is conducive to increasing the compactness of the packaging machine as a whole and reducing the volume of the equipment.
