A support platform 9 is fixed to the top of the connecting shaft 8. The support platform 9 is located above the conveyor belt 1. Scanners 10 for identifying the outline of paper products are installed around the bottom of the movable box 4.

[0032] The clamping plate 5 is provided with a support plate 11 and an extrusion plate 12 respectively;

[0033] The paper products are transferred by the conveyor belt 1. When the paper products are transferred to the top of the support platform 9, the scanner 10 scans the outline of the paper products and adjusts the orientation with the cooperation of the rotating motor 7. Then the clamping assembly 6 drives the clamping plate 5 to clamp the paper products. At the same time, the electric push rod 17 drives the movable box 4 to move downward, so that the clamping plate 5 moves downward, and the paper products slide upward on the clamping plate 5. The paper products can be stacked layer by layer according to the way they are transported, or they can be clamped and fixed in a whole pile, providing a variety of packaging methods.

[0034] Among them, Figure 2 As shown:

[0035] The driving assembly 3 includes two groups of rotating shafts 31 that rotate in the inner cavity of the fixed frame 2 through bearings. Rollers 32 are fixed to the outside of the rotating shafts 31, and the conveyor belt 1 is sleeved on the outside of the rollers 32. A driving motor 33 is fixed to the outside of the fixed frame 2. The output shaft of the driving motor 33 passes through the fixed frame 2 and is fixedly connected to one end of a group of rotating shafts 31. The driving motor 33 drives the rotating shafts 31 to rotate, and synchronously drives multiple groups of rollers 32. The rollers 32 are used to drive the conveyor belt 1 to rotate, which facilitates the transportation and transfer of paper products.

[0036] Further, such as Figure 4 As shown:

[0037] The clamping assembly 6 includes two groups of movable seats 61 located in the inner cavity of the movable box 4. A threaded sleeve is embedded in the center of the movable seat 61, and the inner cavity of the threaded sleeve is threadedly connected to a bidirectional threaded rod 62. Both ends of the bidirectional threaded rod 62 rotate in the inner cavity of the movable box 4 through bearings. A servo motor 63 is fixed to the outside of the movable box 4. The output shaft of the servo motor 63 passes through the inner cavity of the movable box 4 and is fixedly connected to one end of the bidirectional threaded rod 62. A through groove 64 is provided at the bottom of the movable box 4. Two groups of clamping plates 5 pass through the through groove 64 and are fixed to the bottom of a group of movable seats 61. The bidirectional threaded rod 62 is driven to rotate by the servo motor 63, and then the bidirectional threaded rod 62 drives the movable seat 61 to move inward in the movable box 4 through the threaded sleeve, driving the clamping plate 5 to clamp and fix the paper product from the outside, and cooperate with the support platform 9 to facilitate the installation of paper products in the same position and direction for stacking.

[0038] Preferably, Figure 5-6 As shown:

[0039] A storage groove is provided on the opposite side of the clamping plate 5, and a driving motor 13 is fixed to the top of the inner cavity of the storage groove. A screw rod 14 is fixed to the output shaft of the driving motor 13. The end of the screw rod 14 away from the driving motor 13 rotates at the bottom of the inner cavity of the storage groove through a bearing. The screw rod 14 threadedly passes through one end of the extrusion plate 12, and the screw rod 14 is driven to rotate by the driving motor 13, so that the extrusion plate 12 slides up and down on the screw rod 14, which is convenient for adjusting the height of the pressure plate, thereby adjusting the distance between the extrusion plate 12 and the support plate 11, and facilitating the clamping and limiting of paper products of different heights.

[0040] It is worth noting that if Figure 5-6 As shown:

[0041] A limiting ridge 15 is provided on the opposite side of the clamping plate 5. The limiting ridges 15 are arranged at equal intervals and are used to limit and prevent the paper products from slipping. By setting the limiting ridges 15, the friction between the paper products and the clamping plate 5 is increased to prevent the paper products from falling and sliding downward under the influence of gravity, which affects the limiting effect on the paper products.

[0042] In a further preferred embodiment, Figure 1 and Figure 3 As shown:

[0043] A fixing frame 16 is fixed to the outside of the fixing frame 2, and four sets of electric push rods 17 are installed on the top of the fixing frame 16. The piston rods of the electric push rods 17 pass through the fixing frame 16 and are fixed to the top of the movable box 4. The electric push rods 17 are installed through the fixing frame 16. At the same time, the electric push rods 17 can drive the movable box 4 to move up and down, adjust the overall height of the clamping plate 5 and the movable box 4, and facilitate the transfer of the clamping plate 5 to the outside of the paper product, clamp the paper product from the outside, and be used in conjunction with the conveyor belt 1.

[0044] In addition, if Figure 3 As shown:

[0045] Limiting rods 18 are fixed around the top of the movable box 4. The top of the limiting rod 18 passes through the fixing frame 16 and extends upward. A supporting spring 19 is sleeved on the outer side of the limiting rod 18. The two ends of the supporting spring 19 are respectively fixed on the fixing frame 16 and the movable box 4. Through the setting of the limiting rod 18, the stability of the movable box 4 in the fixing frame 16 is ensured, and the movable box 4 is prevented from shaking, causing the clamping plate 5 to shake therewith. At the same time, the supporting spring 19 assists in pulling and supporting the movable box 4, protects the electric push rod 17, and helps to improve the service life of the electric push rod 17.

[0046] In this embodiment, if Figure 4 As shown:

[0047] A sliding sleeve is embedded in the movable seat 61, and a sliding rod 20 is slidingly provided in the inner cavity of the sliding sleeve. Both ends of the sliding rod 20 are fixed on the inner wall of the movable box 4. The sliding rod 20 slides in the sliding sleeve, which makes it convenient to use the sliding rod 20 to limit the movable seat 61, preventing the movable seat 61 from shaking in the movable box 4, and rotating on the outside of the bidirectional threaded rod 62, while assisting the movable seat 61 to slide.

[0048] In addition, if Figure 6 As shown:

[0049] A groove is provided on the opposite side of the clamping plate 5, and the inner cavity of the groove is rotatably connected to a movable shaft 21 through a bearing. The support plate 11 is fixed on the movable shaft 21. Torsion springs 22 are fixed at both ends of the movable shaft 21, and the other end of the torsion spring 22 is fixed to the inner wall of the groove. The support plate 11 is located below the extrusion plate 12, and the movable shaft 21 is limited by the torsion spring 22 to ensure that the support plate 11 is perpendicular to the clamping plate 5 without being disturbed by external forces. The clamping plate 5 is used to support the paper product. At the same time, when the paper product is located below the support plate 11, the support plate 11 can be used as a limit to prevent the paper product from moving up.

[0050] In this embodiment, if Figure 6 As shown:

[0051] The bottom of the extrusion plate 12 is provided with multiple groups of chambers, and rollers 23 are movably arranged in the chambers. The setting of the rollers 23 at the bottom of the extrusion plate 12 can prevent the extrusion plate 12 from leaving scratches on the paper product when it is squeezed by the clamping plate 5.

[0052] When used specifically, they are differentiated according to the way paper products are transported:

[0053] When paper products are transported one by one on the conveyor belt, the drive motor 33 is started, the drive motor 33 drives the rotating shaft 31 to rotate, the rotating shaft 31 drives the roller 32 to rotate, and drives the conveyor belt 1, so that the conveyor belt 1 transports paper products one by one. After the paper product is transferred to the top of the support table 9, the scanner 10 at the bottom of the movable box 4 scans and identifies the outline of the paper product. When the orientation of the rear paper product is inconsistent with the orientation of the previous paper product, after the paper product moves to the top of the support table 9, the rotating motor 7 drives the support table 9 to rotate and adjust the orientation. Then the electric push rod 17 drives the movable box 4 to move downward, and at the same time, the clamping plate 5 moves with the movable box. 4 moves down together and is inserted between the conveyor belts 1, placing the paper products on the inner side of the clamping plate 5. At the same time, the servo motor 63 is started, and the servo motor 63 drives the bidirectional threaded rod 62 to rotate. At the same time, the bidirectional threaded rod 62 drives the movable seat 61 to move inward through the threaded sleeve. At the same time, the movable seat 61 drives the clamping plate 5 to clamp the paper products. The limiting convex strips 15 prevent the paper products from sliding down. Then the movable box 4 moves up under the drive of the electric push rod 17, and the conveyor belt 1 conveys the paper products again. Then the clamping plate 5 moves down directly under the drive of the electric push rod 17, and the paper products are clamped in the clamping plate 5 in turn, forming an upper and lower stack and neatly arranged.

[0054] When paper products are transported in piles, the electric push rod 17 drives the movable box 4 and the clamping plate 5 to move downward, so that the support plate 11 is directly located under the paper products, and then the paper products are clamped. It can directly clamp the piles of paper products.

[0055] Then the packaging box is placed on the top of the support platform 9, and the electric push rod 17 drives the movable box 4 and the clamping plate 5 to move downward, so that the clamping plate 5 is inserted into the packaging box. Then the driving motor 13 drives the screw rod 14 to rotate, and squeezes the extrusion plate 12, so that the paper product is downwardly released from the clamping of the clamping plate 5 and loaded into the packaging box.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
