The open design of the first end 10 and the second end 20 reduces the operation complexity for a user during mounting of a paper roll, improves the working efficiency, is particularly suitable for occasions where the paper roll is replaced frequently, and is more suitable for the paper rolls 80 with different lengths. The paper separating housing 1 is defined by means of a first side wall 30 and a second side wall 40 thereof to form a cavity 2 capable of accommodating the elongated paper roll 80, the user can place the paper roll 80 in the cavity 2 easily or take out same easily, and the mounting and replacement process of the paper roll is simplified. An outer wall from the first end 10 to the second end 20 defines the length of the paper separating housing 1, so that it is ensured that the paper roll 80 can be stably placed during use, the deviation phenomenon of the paper due to shaking of the paper roll is reduced, and the cutting precision is improved. An adhesive tape cutting assembly 5 fixedly mounted on an outer wall of the paper separating housing 1 is configured to be sleeved with an adhesive tape roll 90 and cut an adhesive tape 91. The adhesive tape cutting assembly 5 is fixedly mounted on the outer wall of the paper separating housing 1, thereby achieving the multi-functional integrated design, reducing the operation burden of the user, and improving the overall working efficiency. By means of such integrated design, the space is saved, and the entire device is more compact and beautiful and is convenient to store and carry. A paper picking component 100 includes a first portion 100a and a second portion 100b connected to the first portion 100a, where one end of the second portion 100b is connected to the paper cutting housing 6. In some embodiments, an elastic buckle 15 is arranged at one end of the second portion 100b, and an elastic buckle mounting groove 17 matched with the elastic buckle 15 is formed in the paper cutting housing 6. The first portion 100a is in an elongated shape, one end of the first portion 100a is provided with a flat and pointed tip 11 capable of picking paper upwards, a paper feeding slit 8 is formed between a paper guiding edge 63 of the paper cutting housing 6 and the paper picking component 100, and a paper cutter 4 is arranged inside the slit 8. In some embodiments, the paper cutter 4 is arranged inside a blade mounting groove 16 of the paper picking component 100, and a cutting edge 44 of the paper cutter 4 faces the tip 11 and is configured to cut the paper 70 entering the slit 8. Two ends of a guiding and pressing structure 7 can be respectively arranged on two sides of the paper picking component 100; and during operation of a paper cutting device, the guiding and pressing structure 7 can continuously press the paper 70 entering the slit 8 downwards from two sides of the paper picking component 100 to bend the paper 70, and keep the stiffness and bending tension when the paper 70 is cut by the paper cutter 4. The paper 70 is discharged from a paper discharging groove 65 at a rear end of the paper cutting housing 6 after being cut.
In some embodiments, as shown in FIG. 1-FIG. 2, FIG. 3-FIG. 6 and FIG. 8-FIG. 9, the adhesive tape cutting assembly 5 includes an adhesive tape sleeving shaft 51 connected to the outer wall of the paper separating housing 1 and selectively sleeved with the adhesive tape roll 90, so that the user can replace different types of adhesive tape rolls easily, and the use convenience and flexibility are improved. The adhesive tape sleeving shaft 51 allows the adhesive tape roll 90 to rotate stably so as to pull out the adhesive tape 91, thereby ensuring that when the user pulls out the adhesive tape 91, the adhesive tape roll can rotate smoothly, and the resistance and the jamming phenomenon during pulling-out are reduced. A knife fixing member 53 is arranged on the same side as the adhesive tape sleeving shaft 51 and connected to the outer wall of the paper separating housing 1, so that the space is saved, and the entire device is more compact and beautiful. A serrated knife 52 is mounted on the knife fixing member 53, and the serrated design increases the cutting friction force and ensures rapid, precise and efficient cutting actions. The serrated knife 52 is configured to be capable of cutting the adhesive tape 91 pulled out from the adhesive tape roll 90. The design of the serrated knife 52 can adapt to the adhesive tapes of different thicknesses, and both thin and thick adhesive tapes can be smoothly cut, so that the applicability and versatility of the device are improved.
In some embodiments, as shown in FIG. 1, FIG. 2, FIG. 3-FIG. 6 and FIG. 8-FIG. 9, the adhesive tape cutting assembly 5 further includes a protective assembly 54; the protective assembly 54 includes a sliding member 541 and a spring mounting hole 5411 for mounting a spring 542; and when an external force is applied to the sliding member 541, the sliding member 541 moves along a sliding groove 111 to expose the serrated knife 52 for cutting. The sliding member 541 hides the serrated knife 52 when no external force is applied, thereby ensuring that the cutting edge 44 is not exposed to the outside in a non-use state, reducing the accidental contact risk, and improving the use safety. When the user needs to cut the adhesive tape 91, all that is needed is to apply the external force to enable the sliding member 541 to move along the sliding groove 111, and then the serrated knife 52 can be exposed for cutting. Such design simplifies operation steps, thereby improving the use convenience.
As shown in FIG. 8-FIG. 9, the sliding groove 111 is formed in the paper separating housing 1, the sliding member 541 is provided with a sliding rail 5412, the sliding groove 111 is matched with the sliding rail 5412, and the sliding groove 111 defines a movement range and direction of the sliding member 541. It is ensured that the sliding member 541 moves stably along a predetermined path, the loosening or shaking phenomenon is reduced, and the mechanical reliability of the entire device is improved.
In some embodiments, as shown in FIG. 2 and FIG. 8-FIG. 9, the protective assembly 54 further includes the spring 542, where when the external force is removed from the sliding member 541, the spring 542 provides an elastic force for the sliding member 541, the spring 542 pushes back the sliding member 541 to an initial position, and the cutting edge of the serrated knife 52 is hidden by the sliding member 541. An automatic reset function ensures that the cutting edge of the serrated knife 52 is in a hidden state all the time when not in use, and the need for manual resetting by the user is reduced. The external force needs to be applied once to enable the sliding member 541 to move to expose the serrated knife 52 for cutting, and after the external force is removed, the spring 542 can automatically reset the sliding member 541, so that the operation steps are simplified, and the use convenience is improved. The automatic reset function helps to keep the cleanliness inside the device, reduces the opportunity of external pollutants entering the device, and ensures the long-term stable operation of the device.
The protective assembly 54 further includes a protective member 543 which constitutes a housing portion of the protective assembly 54 and protects and supports the entire structure. The protective member 543 is configured to accommodate and mount the sliding member 541 and support the spring 542. The stability of the spring 542 is ensured when the elastic force is provided, and the failure or deformation of the spring 542 due to external factors is avoided.
In some embodiments, as shown in FIG. 3, the paper cutter 4 is arranged at the second portion 100b of the paper picking component 100, or the paper cutter 4 is arranged inside the paper cutting housing 6, and the cutting edge 44 of the paper cutter 4 faces an inlet (not shown) of the slit 8. If the paper cutter 4 is arranged at the second portion 100b of the paper picking component 100, the deviation of the paper can be reduced, and the cutting precision can be ensured; and if it is arranged inside the paper cutting housing 6, a stable cutting environment is provided, and the cutting quality is further improved. The hidden design of the paper cutter 4 also helps to protect the cutting edge and prolong the service life thereof.
In some embodiments, as shown in FIG. 1-FIG. 9, the paper cutting housing 6 and the paper separating housing 1 are of an integrated structure. The integrated structure provides the higher overall mechanical strength, ensures that the components cannot be loosened or separated during use, and enhances the stability and reliability of the device. The user can implement paper separating, paper cutting and adhesive tape cutting functions in the integrated device, thereby reducing the switching among different devices, and improving the working efficiency.
In some embodiments, the paper cutting housing 6 and the paper separating housing 1 are of a detachable structure (not shown). The detachable structure allows the user to disassemble and replace damaged or aged components easily, thereby prolonging the service life of the device. For example, if a paper cutting portion or a paper separating portion breaks down, the user can replace the defective portion separately, and the entire device is not required to be replaced. The user can select whether to mount a paper separating assembly according to actual requirements, or flexibly combine and use same according to different use scenes, thereby enhancing the versatility and adaptability of the device. Due to the detachable structure, the interior is easier to clean, the possibility of dust and sundry accumulation is reduced, and the long-term stable operation of the device is maintained.
In some embodiments, the outer side of the paper cutting housing 6 is further provided with a side portion 61 extending downwards, and a lower edge 62 of the side portion 61 can assist in pressing down the paper entering the slit 8. It is ensured that the paper keeps the correct path and the appropriate tension when entering a cutting area. Due to the design of the side portion 61 and the lower edge 62, the paper is more stable when entering the cutting area, and the risk of tearing or damage caused by the sudden stress is reduced.
In some embodiments, as shown in FIG. 2 and FIG. 4-FIG. 6, the integrated paper and adhesive tape cutting device further includes a cavity opening 3 which is formed in the outer wall of the paper separating housing 1, is axially formed from the first end 10 to the second end 20, and is in communication with the cavity 2, where the to-be-cut paper 70 of the paper roll 80 is selectively pulled out from the cavity opening 3, and the first side wall 30 and the second side wall 40 of the paper separating housing 1 adjacent to the cavity opening 3 are selected for paper separation. By means of the cavity opening 3, the user can pull out the to-be-cut paper easily, thereby simplifying the paper taking process, and improving the operation convenience. The design of the cavity opening 3 ensures that the paper is correctly guided and positioned before entering the cutting area, thereby reducing the deviation possibility of the paper, and improving the paper separating precision. The paper is guided out from the cavity opening 3, so that the winding or jamming of the paper in a narrow space can be avoided, the jamming phenomenon during operation is reduced, and the reliability of the device is improved.
In some embodiments, as shown in FIG. 2 and FIG. 4-FIG. 7, the integrated paper and adhesive tape cutting device further includes a support structure 9, where the support structure 9 includes a first group of support wheels 9a, 9b, and the first group of support wheels 9a, 9b are arranged at the bottom of the paper separating housing 1, so that the stable support effect can be provided, and it is ensured that the paper separating housing 1 is kept horizontal and stable during operation. Thus, the entire device is easy to move on a desktop, the user can conveniently adjust the position according to requirements, the use convenience is improved, the device is particularly suitable for operations on the desktop or a plane, and the shaking possibility of the device is reduced. The first group of support wheels 9a, 9b selectively make contact with the paper 70 and support the paper separating housing 1. The design of the support wheels 9a, 9b allows the user to select whether to make contact with the paper 70 according to the actual requirements, thereby providing more operation flexibility. In some embodiments, when the closer contact with the paper is needed, the positions of the support wheels 9a, 9b can be adjusted to enhance the support effect. In some embodiments, when no additional support is needed, the support wheels 9a, 9b can be moved away to avoid unnecessary interference.
In some embodiments, as shown in FIG. 2 and FIG. 4-FIG. 7, the support structure 9 further includes a second group of support wheels 24a, 24b which are mounted by means of support wheel mounting rib plates 66 and connected to the bottom of the paper cutting housing 6, so that the additional support points can be provided for the paper cutting housing 6, and it is ensured that the paper cutting housing is kept horizontal and stable during operation. Particularly, when the thick or large paper is processed, it can be ensured that the device is not inclined or turned over. The design of the second group of support wheels 24a, 24b provides the support function and enables the entire device to be easy to move on the desktop, so that the user can conveniently adjust the position according to requirements, and the use convenience is improved. The second group of support wheels 24a, 24b selectively make contact with the paper 70 and support the paper cutting housing 6. The first group of support wheels 9a, 9b arranged at the bottom of the paper separating housing 1 and the second group of support wheels 24a, 24b arranged at the bottom of the paper cutting housing 6 act jointly to form a double support system. Such design further enhances the stability and reliability of the entire device, and ensures the stable operation of the device particularly when handling complex tasks. The two groups of support wheels are respectively arranged at the bottoms of the different housings, so that the pressure can be dispersed when the device is lifted or moved, the pressure borne by the single support point is reduced, and the service life of the support structure is prolonged.
In some embodiments, as shown in FIG. 2, FIG. 4-FIG. 6 and FIG. 8-FIG. 9, the integrated paper and adhesive tape cutting device further includes a holding portion 60 which is connected to the paper separating housing 1. The holding portion 60 is connected to the paper separating housing 1, thereby providing a convenient holding point for the user. By means of such design, the user can lift or move the entire device more easily, thereby improving the operation convenience. When a force is applied to the holding portion 60, at least one component force is in a direction perpendicular to the support structure 9 to form a bottom plane. By means of such design, when the device is lifted, the component force can effectively offset the gravity of the device, thereby reducing the shaking possibility of the device, and enhancing the overall stability. The component force perpendicular to the bottom plane can provide an additional support when the device is lifted, thereby preventing the device from being inclined or turned over during lifting, and it is particularly important during processing of heavy paper rolls or frequent operations.
In some embodiments, as shown in FIG. 3, an upper surface of the paper picking component 100 from the tip 11 to the cutting edge 44 is a bearing surface 12, and the bearing surface 12 is an arched cambered surface and is configured to make contact with and support the paper 70 upwards. The bearing surface 12 which is the arched cambered surface provides the more uniform support force distribution, thereby avoiding the folding or jamming phenomenon of the paper in case of local uneven stress, and ensuring that the paper smoothly enters the cutting area. Under the guidance effect of the arched cambered surface, the paper can keep the relatively stable path when entering the cutting area, thereby reducing the deviation possibility of the paper, and improving the cutting precision.
In some embodiments, the bottom of the paper picking component 100 is a bottom plane 13 which is close to a support surface formed by the bottom of the support structure 9; and during operation of the paper cutting device, the bottom of the paper picking component 100 abuts against an original placement surface of the paper 70 which is not picked. It is ensured that the paper picking component 100 can stably abut against the original placement surface of the paper 70 which is not picked during operation, thereby reducing the shaking or inclining risk. The bottom plane 13 increases the contact area between the paper picking component 100 and the original placement surface (for example, the desktop), distributes more support force, avoids the situation of uneven local stress, enhances the overall stability, and reduces the risk of tearing or damage of the paper 70 due to sudden stress.
In some embodiments, as shown in FIG. 4-FIG. 6, the guiding and pressing structure 7 includes a paper pushing member 21 which is connected to the paper cutting housing 6 and arranged close to a paper feeding end 64 of the paper cutting housing 6; and the paper pushing member 21 includes a first paper pushing member 21a and a second paper pushing member 21b which are respectively arranged on left and right sides of the paper picking component 100, thereby ensuring that the paper is subjected to uniform left and right pressure when entering the slit 8, and avoiding inclining or jamming of the paper due to uneven stress on the single side. When the to-be-cut paper 70 enters the slit 8, the first paper pushing member 21a and the second paper pushing member 21b position and guide in the to-be-cut paper 70 synchronously in a direction of the cutting edge 44. The paper pushing member 21 provides the stable guidance effect, thereby reducing the jamming or blocking possibility when the paper enters the slit 8, and improving the operation smoothness. When guiding in the paper, the paper pushing member 21 can continuously apply certain pressure to the paper, so that the paper 70 keeps the stiffness when entering the slit 8, and the stability of the paper and the precision during cutting are enhanced.
In some embodiments, as shown in FIG. 4-FIG. 6, the guiding and pressing structure 7 further includes a paper guiding member 23 which is connected to the paper cutting housing 6, the paper guiding member 23 includes a first paper guiding member 23a and a second paper guiding member 23b which are respectively arranged on the left and right sides of the paper picking component 100, and when the to-be-cut paper 70 is guided in from a bottom contact point of the paper pushing member 21 to the cutting edge 44, the first paper guiding member 23a and the second paper guiding member 23b position and guide in the to-be-cut paper 70 in the direction of the cutting edge 44. The first paper guiding member 23a and the second paper guiding member 23b provide the stable guidance effect during guiding in of the paper, so that the paper keeps the fixed path when entering the cutting area, and the stability of the paper and the precision during cutting are enhanced. The first paper guiding member 23a, the second paper guiding member 23b, the first paper pushing member 21a and the second paper pushing member 21b act jointly to form a complete paper guiding-in system. The paper pushing member 21 is responsible for guiding in the paper from the paper feeding end 64, and the paper guiding member 23 ensures that the paper keeps the correct path when entering the cutting area. Such cooperative effect remarkably improves the guiding-in precision and stability of the paper. A double guidance mechanism of the paper guiding member 23 and the paper pushing member 21 can disperse the pressure during guiding-in of the paper, reduces the pressure borne by the single component, and prolongs the service life of the device.
In some embodiments, as shown in FIG. 4-FIG. 6, outer diameters of the first paper pushing member 21a and the second paper pushing member 21b are greater than outer diameters of the first paper guiding member 23a and the second paper guiding member 23b, and a distance between the first paper pushing member 21a and the second paper pushing member 21b is greater than a distance between the first paper guiding member 23a and the second paper guiding member 23b. Under the pressure angle effect formed when the paper 70 enters the cutting area, ends of the paper 70 can be more closely attached to the cutting edge 44, which increases the pressure during cutting, and improves the cutting effect and precision. The paper pushing member 21 with the large outer diameter and the small paper guiding member 23 can provide the relative pressure during guiding-in of the paper 70, so that the paper 70 forms a pressure angle and keeps certain stiffness and tension, the paper 70 is flatter during cutting, and the deviation or jamming risk of the paper 70 is reduced. Meanwhile, by means of the stable support provided by the paper pushing member 21 and the paper guiding member 23 during guiding-in of the paper, the risk of damage caused by excessive bending or folding of the paper is reduced, and the integrity of the paper is protected.
In some embodiments, as shown in FIG. 4-FIG. 6, the first paper pushing member 21a and the second paper pushing member 21b are connected by means of a fixing shaft member 22 and are rotationally connected to the bottom of the paper cutting housing 6 by means of paper pushing member mounting rib plates 67, and the first paper pushing member 21a and the second paper pushing member 21b are a group of rollers with the same outer diameter, so that the pressure applied to the paper is distributed more uniformly, and the risk of damage of the paper due to excessive local stress is reduced. The first paper pushing member 21a and the second paper pushing member 21b can rotate synchronously. The first paper guiding member 23a and the second paper guiding member 23b are connected by means of a fixing shaft member 22 and are rotationally connected to the bottom of the paper cutting housing 6 by means of paper guiding member mounting rib plates 68, the first paper guiding member 23a and the second paper guiding member 23b are a group of rollers with the same outer diameter, and the first paper guiding member 23a and the second paper guiding member 23b can rotate synchronously. Thus, the paper can keep the relatively stable path when entering the cutting area, thereby reducing the deviation possibility of the paper, and improving the guiding-in precision and stability. The roller design reduces the friction force between the paper and the surface of the device, so that the paper can be guided into the cutting area more easily, the jamming phenomenon is reduced, and the operation smoothness is improved. The paper pushing member 21 and the paper guiding member 23 are detachably mounted on the inner wall of the paper cutting housing 6 by means of the fixing shaft members 22, so that the user can disassemble and replace the damaged or aged components easily, thereby prolonging the service life of the device. The design of the fixing shaft members 22 ensures that the paper pushing member 21 and the paper guiding member 23 can be aligned accurately and rotate synchronously, thereby ensuring the precision and stability of the paper during guiding-in.
The above are merely some embodiments of the present application and are not intended to limit the present application, and various changes and variations may be made on the present application by those skilled in the art. Any modification, equivalent substitution, improvement, etc. made within the spirit and principles of the present application should fall within the scope of protection of the present application.
