[0002] A paper stacking device is a device that quickly divides a stack of paper into several smaller stacks to meet the needs of subsequent production and processing.

[0003] Currently, some paper stacking devices separate the paper from the stack by applying friction to the bottom of the paper towel, thus forming several small stacks; however, the separated paper is scattered on one side of the device, and manual sorting of the separated paper is still required. Summary of the Invention

[0004] The purpose of this invention is to provide a paper stacking device that allows separated papers to be neatly stacked to one side without the need for manual stacking.

[0015] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects: The paper stacking device of the present invention places the paper stack between two limiting plates. A driving mechanism drives a friction mechanism to separate the bottom paper from the paper stack onto a placement member. The driving mechanism also causes the placement member to slide downwards with the movement of the friction mechanism, ensuring that each sheet separated from the paper stack lands on the placement member. As the placement member continues to slide downwards, several sheets of paper form small stacks on the placement member, thereby achieving paper stacking. Through the above solution, the present invention allows the paper to be neatly separated onto the placement member, eliminating the need for manual stacking and increasing efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] Please refer to Figures 1-5 A paper stacking device includes a frame 1, two limiting plates 2, a friction mechanism 3, a placement component 4, a driving component, and a guide column 6.

[0024] like Figure 1 As shown, the top of the frame 1 has a protrusion, and two limiting plates 2 are respectively arranged facing each other on the top of the frame 1, forming a limiting space for placing paper with the protrusion of the frame 1; one end of the two limiting plates 2 extends outward to the outside of the frame 1, and the end also extends downward.

[0025] In this embodiment, the downward sides of the two limiting plates 2 are also provided with two abutment plates, which facilitates the placement of the paper stack between the two limiting plates 2.

[0026] like Figure 1 As shown, the placement component 4 includes a placement plate 41 and two sliders 42. The two sliders 42 are respectively disposed on both sides of the placement plate 41. The placement plate 41 is slidably disposed on the opposing sidewalls of the two limiting plates 2 extending to one end of the frame 1. The paper separated by the friction mechanism 3 falls onto the placement plate 41.

[0027] In this embodiment, in order to prevent the paper from sliding off the placement plate 41, a stop block 411 is provided at the end of the placement plate 41 away from the frame 1 to hold the paper in place and limit its movement.

[0028] like Figure 1 and Figure 4 As shown, the friction mechanism 3 includes a first connecting rod 33 and several friction parts. The friction parts include a belt 32, a pulley 31, a connecting wheel 34, a pawl ring 35, several first pawls 36, and several first spring plates 37. The frame 1 has a groove, and the first connecting rod 33 is rotatably disposed in the groove. A plurality of connecting wheels 34 are mounted on a first connecting rod 33. A pawl ring 35 is rotatably mounted on the connecting wheels 34. A plurality of first pawls 36 are rotatably mounted on the connecting wheels 34 and engage with the pawl ring 35. The two ends of a first spring plate 37 are connected to the first pawls 36 and the connecting wheels 34, respectively. A plurality of pulleys 31 are rotatably mounted in a groove. A belt 32 is fitted onto the pulleys 31 and the connecting wheels 34. The rotation of the first connecting rod 33 drives the connecting disc to rotate. Under the action of the first pawls 36, the pawl ring 35 drives the belt 32 to rotate, using friction to separate the paper at the bottom of the paper stack. When the first connecting rod 33 rotates in the opposite direction, the first pawls 36 will not drive the pawl ring 35 to rotate, so that the connecting wheels 34 and the belt 32 are stationary. The first spring plate 37 is used to drive the first pawls 36 to reset, so that the first pawls 36 can be locked in the pawl ring 35.

[0029] like Figures 1-3 As shown, the driving mechanism 5 is used to drive the friction mechanism 3 to rotate, and the placement plate 41 slides downward with the movement of the friction mechanism 3. If the position of the placement plate 41 is fixed, there are two situations: one is that the height of the placement plate 41 is parallel to the height of the frame 1, which will prevent the separated papers from being stacked on the placement plate 41; the other is that the height of the placement plate 41 has a certain height difference with the frame 1, which will cause the separated papers to fall downward during the process of falling on the placement plate 41, making it difficult for the papers to be neatly stacked in a stack on the placement plate 41. Based on this, this embodiment solves the problems mentioned above by moving the placement plate 41 downward a fixed distance for each paper separated by the friction mechanism 3.

[0030] Specifically, the drive mechanism 5 includes a first telescopic rod 501, a first gear 503, a rack 502, a connecting plate 504, a second pawl 505, a ratchet 506, a linkage component, and a separation component. The linkage component includes a second gear 507, a third gear 508, a first bevel gear 509, a second bevel gear 510, a third bevel gear 511, a fourth bevel gear 512, a second connecting rod 520, and a lead screw 513. The separation component includes a third telescopic rod 517, a second spring plate 518, and two magnets.

[0031] The frame 1 has a cavity. One end of the first connecting rod 33 extends into the frame 1 and is connected to the first gear 503. The ratchet 506 is rotatably connected to the first gear 503. The rack 502 is slidably disposed in the cavity and meshes with the first gear 503. One end of the first telescopic rod 501 is connected to the cavity, and the other end is connected to the rack 502. The connecting plate 504 is connected to the first gear 503. The second pawl 505 is rotatably disposed on the connecting plate 504 to actuate the ratchet 506 to rotate in one direction. The first telescopic rod 501 extends, causing the rack 502 to move upward, which causes the first gear 503 to drive the first connecting rod 33 to rotate, thereby driving the pulley 31 to rotate, so that the belt 32 carries the paper. The paper is separated from the stack of paper; simultaneously, the connecting plate 504 rotates with the first gear 503. At this time, the second pawl 505 engages with the ratchet 506, causing the ratchet 506 to rotate; the first telescopic rod 501 shortens, driving the gear to move downwards, causing the first gear 503 to rotate in the opposite direction. As the first gear 503 rotates in the opposite direction, the second pawl 505 will not cause the ratchet 506 to rotate, and the ratchet 506 remains stationary, not rotating with the first gear 503 in the opposite direction; at the same time, as the first gear 503 rotates in the opposite direction, the connecting wheel 34 and the belt 32 remain stationary; repeating the above steps causes the belt 32 to intermittently provide friction to the paper to separate the paper at the bottom of the stack of paper.

[0032] In this embodiment, as Figure 5 As shown, a number of balls 519 are provided between the ratchet 506 and the first gear 503 to reduce the friction between the ratchet 506 and the first gear 503, so that when the first gear 503 rotates, the ratchet 506 will not be driven to rotate due to friction.

[0033] The second gear 507 is connected to the ratchet 506. The third gear 508 is rotatably disposed in the cavity and meshes with the second gear 507. The first bevel gear 509 is connected to the third gear 508. The second connecting rod 520 is rotatably disposed in the cavity, with one end connected to the second bevel gear 510 and the other end extending outside the frame 1 and connected to the third bevel gear 511. The lead screw 513 is rotatably disposed on the frame 1, with a fourth bevel gear 512 at its top. The first bevel gear 509 meshes with the second bevel gear 510, and the third bevel gear 511 meshes with the fourth bevel gear 512. One of the sliders 42 has a screw... The screw 513 has a threaded hole at one end; when the ratchet 506 rotates, the force is transmitted to the screw 513 along the directions of the second gear 507, the third gear 508, the first bevel gear 509, the second bevel gear 510, the second connecting rod 520, the third bevel gear 511, and the fourth bevel gear 512, driving the screw 513 to rotate, thereby causing the slider 42 to move downward along the screw 513; with each extension of the first telescopic rod 501, the slider 42 is driven to move downward along the screw 513 a certain distance, so as to achieve the effect of the placement part 4 sliding downward with the movement of the friction mechanism 3.

[0034] It should be noted that the diameter of the third gear 508 is much larger than that of the second gear 507. Through the gear transmission ratio, the slider 42 slides down only a very small distance with each extension of the first telescopic rod 501.

[0035] In this embodiment, as Figure 1 As shown, another slider 42 is also provided with a through hole. The guide post 6 is set on the frame 1 and passes through the through hole of the slider 42 to play a guiding role, so that the placement plate 41 slides smoothly.

[0036] The motor 515 is slidably disposed in the cavity, and its output end is connected to the fourth gear 514; one end of the second telescopic rod 516 is connected to the cavity, and the other end is connected to the motor 515, which drives the motor 515 to slide in the cavity by extending and shortening; the third telescopic rod 517 is disposed on the connecting plate 504, one end of which is connected to one of the magnets, and the other magnet is disposed on the second pawl 505, with the magnetic poles of the two magnets facing opposite directions; the second spring plate 518 connects the second pawl 505 and the connecting plate 504, and when the two magnets are separated, the second spring plate 518 drives the second pawl 505 to reset and engage in the ratchet 506; when the placement plate 41 is at the bottom, the third telescopic rod 517 extends, and under the action of the magnets... The second pawl 505 is disengaged from the ratchet 506, and the second telescopic rod 516 drives the motor 515 to slide to the dead center position. At this time, the fourth gear 514 meshes with the second gear 507, and the motor 515 rotates, causing the fourth gear 514 to drive the second gear 507 to rotate in the opposite direction. The lead screw 513 rotates in the opposite direction, and the slider 42 moves upward. Since the second pawl 505 is disengaged from the ratchet 506 at this time, there is no motion interference in the rotation of the second gear 507. When the height of the placement plate 41 is restored, the third telescopic rod 517 shortens. When it reaches the dead center position of the second pawl 505, the two magnets separate. Under the action of the second spring plate 518, the second pawl 505 springs back and gets stuck in the pawl.

[0037] The working principle of this embodiment is as follows: The paper stack is placed between two limiting plates 2. The driving mechanism 5 drives the friction mechanism 3 to separate the bottom paper from the paper stack onto the placement piece 4. The driving mechanism 5 also causes the placement piece 4 to slide downward with the movement of the friction mechanism 3, so that each piece of paper separated from the paper stack can fall onto the placement piece 4. As the placement piece 4 continues to slide downward, several pieces of paper form small stacks on the placement piece 4, thereby realizing the stacking of the paper stack.

[0038] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
