FIELD OF THE INVENTION
The present invention relates to the technical field of paper transmission, in particular to a paper feeding mechanism and a printing equipment.
BACKGROUND OF THE INVENTION
In the prior art, a paper lifting tray of a paper feeding mechanism can adjust an inclination angle thereof according to a condition of paper. In the prior art, a height of one end of the paper lifting tray is usually limited by a way that a limiting component abuts against a guide rod of the paper lifting tray, in order to adjust the inclination angle of the paper lifting tray. However, when a user lifts up a paper feeding tray to take paper, the guide rod of the related paper feeding mechanism is easy to be dislocated, thus releasing a control of the limiting component on the paper lifting tray, which makes it difficult to reposition the paper lifting tray.
SUMMARY OF THE INVENTION

The paper lifting tray rotates away from the paper feeding tray and drive the guide rod to move away from the paper feeding tray. The limiting component is connected with the main body, and includes a limiting member and a driving component. The limiting member abuts against the guide rod to resist the paper lifting tray rotating away from the paper feeding tray. When the paper feeding tray rotates away from the main body, the guide rod disengaged from the limiting member and moves to a side of the limiting member away from the paper feeding tray, the driving component drives the limiting member to rotate to a side of the guide rod away from the paper feeding tray to make the limiting member abut against the guide rod, and the driving component drives the limiting member to drive the guide rod to move towards the paper feeding tray thereby driving the paper lifting tray to move towards the paper feeding tray.

In related technology, a paper lifting tray of a paper feeding mechanism can adjust an inclination angle thereof according to a condition of paper. In the prior art, a height of one end of the paper lifting tray is usually limited by a way that a limiting component abuts against a guide rod of the paper lifting tray, in order to adjust the inclination angle of the paper lifting tray. A paper feeding tray and the paper lifting tray can feed paper for a printing equipment, and the printing equipment can store the paper in a paper storage cavity under the paper feeding tray after completing a printing of the paper. In order to facilitate a user to take paper, the paper feeding tray can be lifted up to provide the user with a wider view and a larger space for taking paper. However, when the user lifts up the paper feeding tray to take paper, the guide rod of the related paper feeding mechanism is easy to be dislocated, so that a control of the limiting component on the paper lifting tray is released, and the paper lifting tray is difficult to be repositioned.
Therefore, some embodiments of the present invention provide a paper feeding mechanism 1000, particularly referring to FIGS. 1 to 10 of the accompany drawings.
Referring to FIGS. 1, 2, and 3, a paper feeding mechanism 1000 in an embodiment of the present invention can be applied to a printing equipment, and specifically, the paper feeding mechanism 1000 can feed paper for the printing equipment. The paper feeding mechanism 1000 includes: a main body 100, a paper feeding component 200, and a limiting component 300. The paper feeding component 200 is arranged at a side of the main body 100. Specifically, the paper feeding component 200 includes a paper feeding tray 210 apart from the main body 100, and a paper lifting tray 220 so that the paper feeding tray 210 and the main body 100 are surrounded to form a paper storage cavity 111. It should be understood that the printing equipment may receive paper fed by the paper feeding component 200 and complete a printing, and send out the paper after completing the printing, and the sent out paper can be temporarily stored in the paper storage cavity 111 to wait for taking by the user.
It should be noted that, since the paper feeding tray is located at the side of the main body, the paper feeding tray may cause a certain obstacle when a user takes the paper in the paper storage cavity, which may cause an inconvenience to the user. Based on this, referring to FIGS. 1, 2 and 3, in an embodiment of the present invention, the paper feeding tray 210 is rotatably connected with the main body 100. Specifically, the paper feeding tray 210 rotates towards or away from the main body 100. When a user takes paper, the user may lift up the paper feeding tray 210 to drive the paper feeding tray 210 to rotate away from the main body 100 to obtain a wider view and a larger space for taking paper, and when the user finishes taking paper, the user may put down the paper feeding tray 210 to drive the paper feeding tray 210 to rotate towards the main body 100 to reposition the paper feeding tray 210.
In order to enable the paper feeding mechanism 1000 to adjust paper feeding strength according to a condition of paper, referring to FIGS. 1, 2 and 3, in an embodiment of the present invention, the paper lifting tray 220 may be rotatably connected with the paper feeding tray 210 so that an inclination angle of the paper lifting tray 220 is adjusted according to the condition of paper, thereby adjusting a paper feeding strength. It should be noted that, the condition of paper may include paper specification, paper material, paper quantity, etc., which is not limited in the embodiments. Specifically, the paper feeding tray 210 may have a recessed position adapted to fit the paper lifting tray 220, and the paper lifting tray 220 may be arranged in the recessed position. One end of the paper lift tray 220 is rotatably connected with the paper feeding tray 210, and other end of the paper lift tray 220 has a guide rod 221 slidably connected with the paper feeding tray 210. The paper lifting tray 220 rotates away from the paper feeding tray 210 and drive the guide rod 221 to move away from the paper feeding tray 210. It is understood that the paper lifting tray 220 may keep a tendency to rotate away from the paper feeding tray 210, that is, the guide rod 221 may always keep a tendency to move away from the paper feeding tray 210. In an embodiment of the present invention, an elastic member 500 may be arranged between the paper lifting tray 220 and the paper feeding tray 210, the elastic member 500 may drive the paper lifting tray 220 to rotate away from the paper feeding tray 210, and the paper lifting tray 220 may also be driven to rotate by a driving device, which is not limited in the embodiments.
In order to limit the inclination angle of the paper lifting tray 220, referring to FIGS. 1, 2 and 3, in an embodiment of the present invention, a limiting component 300 is connected with the main body 100, and includes a limiting member 310 and a driving component 320. The limiting member 310 abuts against the guide rod 221 to resist the paper lifting tray 220 rotating away from the paper feeding tray 210. Specifically, referring to FIG. 4, when the limiting member 310 is in a first state, the limiting member 310 may be located on a side of the guide rod 221 away from the paper feeding tray 210, and the limiting member 310 abuts against one end of the guide rod 221 away from the paper feeding tray 210 and applies a pressure to the guide rod 221 towards the paper feeding tray 210 to offset a potential energy of the paper lifting tray 220 rotating away from the paper feeding tray 210, thereby limiting an inclination angle of the paper feeding tray 210.
It can be understood that the guide rod 221 and the limiting member 310 are not fixedly connected, so there is a possibility that the guide rod 221, driven by the paper lifting tray 220 or the paper feeding tray 210, disengages from the limiting member 310. After the guide rod 221 disengages from the limiting member 310, the limiting member 310 loses an ability to limit the guide rod 221. Referring to FIG. 5, at this time, the guide rod 221 may drive the paper lifting tray 220 to rotate away from the paper feeding tray 210, and the guide rod 221 moves to the side away from the paper feeding tray 210. Therefore, the limiting member 310 releases restriction on the guide rod 221, thus the limiting member 310 and the guide rod 221 are in a second state.
Based on this, in order to enable the limiting member 310 to be repositioned in a position to limit the guide rod 221 and drive the guide rod 221 to be repositioned, as shown in FIGS. 5 and 7, in an embodiment of the present invention, when the paper feeding tray 210 rotates away from the main body 100, the guide rod 221 disengages from the limiting member 310 and moves to a side of the limiting member 310 away from the paper feeding tray 210, that is, the limiting member 310 and the guide rod 221 are in the second state. Then, the driving component 320 drives the limiting member 310 to rotate to the side of the guide rod 221 away from the paper feeding tray 210 to make the limiting member 310 abut against the guide rod 221. At this time, the limiting member 310 is in a fourth state. It should be noted that, as shown in FIG. 7, in an embodiment of the present invention, the limiting member 310 may rotate clockwise, thereby rotating to the side of the guide rod 221 away from the paper feeding tray 210, or may rotate counterclockwise, and after passing over the guide rod 221, rotate to the side of the guide rod 221 away from the paper feeding tray 210, which is not limited in the embodiments. In order to reposition the guide rod 221 and the paper lifting tray 220, in an embodiment of the present invention, the driving component 320 further drives the limiting member 310 to drive the guide rod 221 to move toward the paper feeding tray 210, thereby driving the paper lifting tray 220 to rotate towards the paper feeding tray 210, thus realizing reposition of the guide rod 221 and the paper lifting tray 220, and restoring the guide rod 221 and the limiting member 310 from the fourth state to the first state.
In the embodiments of the present invention, the paper feeding component 200 is arranged on the side of the main body 100, so that the paper storage cavity 111 is formed between the paper feeding tray 210 and the main body 100, and the paper feeding tray 210 is rotatably connected with the main body 100. Therefore, a user can lift up the paper feeding tray 210 to take paper more conveniently and quickly. The limiting member 310 is arranged to abut against the guide rod 221 to resist the paper lifting tray 220 rotating away from the paper feeding tray 210, thereby realizing a control of the inclination angle of the paper lifting tray 220, and improving the controllability of the paper lifting tray 220. Furthermore, the driving component 320 is arranged such that when the user lifts up the paper feeding tray 210 which causes the guide rod 221 to be dislocated, the driving component 320 can drive the limiting member 310 to rotate to the side of the guide rod 221 away from the paper feeding tray 210 to make the limiting member 310 abut against the guide rod 221, so that the limiting member 310 can be repositioned in the position to limit the guide rod 221, and the guide rod 221 is under control of the limiting member 310 again. After the limiting member 310 abuts against the guide rod 221 again, the driving component 320 can drive the limiting member 310 to drive the guide rod 221 to move towards the paper feeding tray 210, thereby driving the paper lifting tray 220 to rotate towards the paper feeding tray 210, thus realizing automatic reposition of the paper lifting tray 220, which reduces a risk of failure of the paper feeding mechanism 1000, reduces a requirement of manual intervention, improves the reliability and the stability of the paper feeding mechanism 1000, and brings better use experience.
Referring to FIGS. 2, 3 and 10, in an embodiment of the present invention, there may be two limiting members 310 arranged spaced apart and connected by a connecting rod 340, thereby realizing synchronous rotation of the two limiting members 310. The driving component 320 may be connected with the connecting rod 340 to drive the two limiting members 310 to rotate. Correspondingly, the guide rod 221 may insert into the paper lifting tray 220. Additionally, two ends of the guide rod 221 may protrude from two ends of the paper lifting tray 220, and the two limiting members 310 may abut against corresponding two end portions of the guide rod 221, so that the two ends of the guide rod 221 and the two ends of the paper lifting tray 220 are stressed averagely, which reduces a risk of fracture of the guide rod 221 caused by stress concentration, and improves the stability of the paper lifting tray 220.
Referring to FIGS. 2, 3 and 6, in an embodiment of the present invention, the limiting member 310 may include a swinging portion 311 and a rotating portion 312. The swinging portion 311 and a rotating portion 312 may be rotatably connected, and the swinging portion 311 may also be rotatably connected with the main body 100. In the embodiment, when the limiting member 310 is located between the guide rod 221 and the paper feeding tray 210, the limiting member 310 and the guide rod 221 are in the second state. In order to enable the limiting member 310 to be repositioned in the position to limit the guide rod 221, the swinging portion 311 swings toward the guide rod 221. When one end of the guide rod 221 towards the paper feeding tray 210 abuts against the rotating portion 312, the rotating portion 312 is unable to continue to rotate along with the swinging portion 311. Then, the rotating portion 312 rotates around the swinging member under an action of the guide rod 221, so that the limiting member 310 as a whole is in a bent state, that is, the limiting member 310 and the guide rod 221 are in a third state. After being bent, the limiting member 310 can continue to rotate away from the paper feeding tray 210 and pass over the guide rod 221. Specifically, the swinging portion 311 drives the rotating portion 312 to move to the side of the guide rod 221 away from the paper feeding tray 210 to abut against the one end of the guide rod 221 away from the paper feeding tray 210, so that the limiting member 310 can be repositioned in the position to limit the guide rod 221. Therefore, a rotation stroke of the limiting member 310 is reduced, the rotation time of the limiting member 310 is shortened, and the efficiency of the limiting component 300 for repositioning the paper lifting tray 220 is improved.
Referring to FIGS. 2, 8 and 10, in an embodiment of the present invention, the limiting component 300 may include a repositioning member 330. One end of the repositioning member 330 is connected with the swinging portion 311, and another end of the repositioning member 330 is connected with the rotating portion 312. It should be noted that the repositioning member 330 may be a tension spring, and based on this, a relaxed state of the repositioning member 330 is a state in which the limiting member 310 as a whole is in a straight state, and when the rotating portion 312 rotates relative to the swinging portion 311, the repositioning member 330 is in a tight state. Accordingly, when the swinging portion 311 drives the rotating portion 312 to move from the side of the guide rod 221 towards the paper feeding tray 210 to the side of the guide rod 221 away from the paper feeding tray 210, the repositioning member 330 can drive the rotating portion 312 to rotate away from the guide rod 221 to be repositioned due to the rotating portion 312 losing a pressing force of the guide rod 221, so that the limiting member 310 is restored from the bent state to the straight state.
It is understood that when the paper feeding tray 210 rotates away from the main body 100, the paper feeding tray 210 drives the paper lifting tray 220 and the guide plate to move away from the limiting component 300, thereby disengaging the guide rod 221 from the limiting member 310. In order to know the dislocation of the guide rod 221 in time, referring to FIGS. 1, 2 and 3, in an embodiment of the present invention, the paper feeding mechanism 1000 may include a sensor 400 arranged on the main body 100. Specifically, the sensor 400 may be fixedly connected with the main body 100 and located on a side of the paper feeding component 200. It should be noted that the sensor 400 may detect whether the paper feeding tray 210 rotates relative to the main body 100. Based on this, the sensor 400 may be triggered when the paper feeding tray 210 rotates away from the main body 100, and the sensor 400 in turn triggers the driving member 320 to drive the limiting member 310 to rotate. That is, whether the guide rod 221 is dislocated may be confirmed by detecting whether the paper feeding tray 210 rotates away from the main body 100 by the sensor 400, or when the paper feeding tray 210 rotates away from the main body 100 and the paper feeding tray 210 rotates to a position where the guide rod 221 is dislocated, the sensor 400 is triggered, thereby confirming whether the guide rod 221 is dislocated. When the guide rod 221 is confirmed to be dislocated, the sensor 400 triggers the driving component 320 in time to drive the limiting member 310 to be repositioned in a position to limit the guide rod 221, which not only improves the efficiency of repositioning the guide rod 221, but also improves an automation degree of the paper feeding mechanism 1000, and reduces the requirement of manual intervention.
Referring to FIGS. 1, 2 and 9, in an embodiment of the present invention, the main body 100 may include a base 110 and a mounting base 120. The base 110 may be arranged under the paper feeding tray 210. The base 110 and the paper feeding tray 210 are surrounded to form a paper storage cavity 111. The mounting base 120 may be arranged on above the base 110 and located on a side of the paper feeding component 200. The mounting base 120 may be integrally formed with the base 110, or the mounting base 120 and the base 110 may also be fixedly connected by a screw connection or a snap connection, which may be selected by a person having ordinary skill in the art according to actual situations and is not limited in the embodiments. The mounting base 120 may be rotatably connected with the paper feeding tray 210, that is, the paper feeding tray 210 may rotate around the mounting base 120 towards or away from the base 110. The mounting base 120 may have a first guiding groove 121, and the paper feeding tray 210 may have a guiding member 211 slidably connected with the first guiding groove 121. Specifically, the guiding member 211 may insert into the first guiding groove 121, and when the paper feeding tray 210 rotates around the mounting base 120 towards or away from the base 110, the guiding member 211 moves along the first guiding groove 121 under the driving of the paper feeding tray 210. It can be understood that the first guiding groove 121 restricts a movement of the guiding member 211, thereby guiding the rotation of the paper feeding tray 210, which improves a direction accuracy of the rotation of the paper feeding tray 210.
Referring to FIGS. 1, 2 and 10, in an embodiment of the present invention, a limiting component 300 may be installed on the mounting base 120. It is understood that the mounting base 120 may have a mounting groove 122 matching with the limiting component 300, and the driving component 320 may be fixedly connected in the mounting groove 122, thereby improving the integrity of the paper feeding mechanism 1000. It should be noted that the driving component 320 may be connected with the mounting base 120 through a screw or a snap, or may also be installed on the mounting base 120 through other forms of fixed connection manners, and a person having ordinary skill in the art may select the arrangement according to actual situations, which is not limited in the embodiments.
Referring to FIGS. 1, 2 and 10, in an embodiment of the present invention, the driving component 320 may include a driver 321, a worm 322, a worm wheel 323, and a transmission component 324. One end of the worm 322 is connected with the driver 321, and another end of the worm 322 is connected with the worm wheel 323. One end of the transmission component 324 is connected with the worm wheel 323, and other end of the transmission component 324 is connected with the limiting member 310. It should be understood that the driver 321 drives the worm wheel 323 to rotate through the worm 322, and the worm wheel 323 in turn drives the connecting rod 340 to rotate through the transmission component 324, thereby driving the limiting member 310. It should be noted that the worm wheel 323 and the worm 322 reduces the rotation speed of the driver 321 to a final rotation speed required by the driving component 320, and a driving component 320 with a larger torque can be obtained through a high reduction ratio. Based on this, the driving component 320 with high-speed reduction ratio can have a self-locking function, which reduces a risk of damage caused by a reverse rotation of the driver 321 due to maloperation of a user, and improves the safety and the reliability of the paper feeding mechanism 1000.
Referring to FIGS. 1, 2 and 3, in the embodiment of the present invention, a second guiding groove 212 may be arranged at a position of the paper feeding tray 210 corresponding to the guide rod 221, and the second guiding groove 212 may be arranged at an end of the paper feeding tray 210 away from a rotational connection position of the paper feeding tray 210 and the paper lifting tray 220. It should be noted that there may be two second guiding grooves 212 arranged at two ends of the paper feeding tray 210, respectively. The guide rod 221 may be slidably connected with the second guiding grooves 212. Specifically, each of the two ends of the guide rod 221 may insert into a correspond one of the two second guiding grooves 212, respectively, so that the second guiding groove 212 may play a role of guiding when the guide rod 221 moves away from the main body 100, which improves an accuracy of a moving direction of the guide rod 221 and an accuracy of a rotating direction of the paper lifting tray 220.
Referring to FIGS. 1 and 2, in an embodiment of the present invention, the paper feeding mechanism 1000 may include an elastic member 500 arranged between the paper feeding tray 210 and the paper lifting tray 220. The elastic member 500 drives the paper lifting tray 220 to rotate away from the paper feeding tray 210. It is understood that the elastic member 500 may serve as a power source for rotating the paper lifting tray 220 away from the paper feeding tray 210. Specifically, when the paper lifting tray 220 is at a lowest position, the elastic member 500 may be in a compressed state, and when a restriction of the guide rod 221 by the limiting member 310 is released, the elastic member 500 may gradually return from the compressed state to a relaxed state, thereby providing power for lifting the paper lifting tray 220.
Referring to FIGS. 1, 2 and 3, in the embodiment of the present invention, two opposite ends of the paper lifting tray 220 may respectively have a connecting portion 222 extending outward therefrom. The paper feeding tray 210 may have a groove 213 corresponding to a respective connecting portion 222, and the connecting portion 222 may insert into a respective groove 213 and may rotate relative to the respective groove 213. Specifically, there are two connecting portions 222, and correspondingly, there are two grooves 213. Each of the two connecting portions 222 is rotatably connected with a respective one of the two grooves 213, thereby realizing a rotating connection between the paper lifting tray 220 and the paper feeding tray 210, and enabling the paper lifting tray 220 to adjust the inclination angle thereof by lifting or lowering.
An embodiment of the present invention further provides a printing equipment including the paper feeding mechanism 1000 of the above embodiments.
Since the printing equipment adopts all technical schemes of the paper feeding mechanism 1000 of the above embodiments, at least all beneficial effects brought by the technical schemes of the above embodiments are achieved, and no further description is provided herein.
The embodiments of the present invention are described in detail above with reference to the accompanying drawings, and finally what should be explained is as follows: the above embodiments are only used for illustrating the technical schemes of the present invention, and not for limiting the same, and although the present invention is described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that modifications may be made to the technical schemes described in the foregoing embodiments, or equivalents may be substituted for some or all of the technical features thereof, without departing from the scope of the embodiments of the present invention.
