[0021] As shown in the figure, the full-automatic pre-feeding mechanism of the die-cutting machine disclosed by the present utility model includes a lifting seat 1 for stacking paper. The lifting seat 1 is connected to a first lifting drive assembly. Specifically, the first lifting drive assembly includes a first motor 7. The output end of the first motor 7 is in transmission connection with a first sprocket 8. A first chain 3 is wound around the first sprocket 8. The first chain 3 is connected to the lifting seat 1. By controlling the operation of the first motor 7 to drive the first chain 3 to move, the lifting seat 1 can be driven to lift and lower. Above the lifting seat 1, there is a moving seat 4. A paper pushing plate 28 is arranged on the moving seat 4. Further, above the paper pushing plate 28, there is a pressing paper belt 31 arranged along its moving path, which can ensure that the stacked paper will not float during the pushing process and improve the stability of paper stack pushing. The moving seat 4 is connected to a first moving drive assembly. Specifically, the first moving drive assembly includes a servo motor 6. The output end of the servo motor 6 is connected to a synchronous pulley. A synchronous belt 5 is wound around the synchronous pulley. The synchronous belt 5 is connected to the moving seat 4. A guiding assembly is arranged corresponding to the moving seat 4. The guiding assembly can be a sliding seat and slide rail structure. By controlling the servo motor 6 to drive the synchronous belt 5 to move, the moving seat 4 and the paper pushing plate 28 can be driven to reciprocate to realize the paper pushing operation. A paper lifting plate 29 is also arranged on the moving seat 4. The paper lifting plate 29 is connected to a second lifting drive assembly. The second lifting drive assembly can be a corresponding air cylinder to drive the paper lifting plate 29 to lift and lower, or a connecting rod structure driven by a motor. On one side of the paper pushing plate 28, there is a first conveyor belt 11. Above the first conveyor belt 11, there is a paper blocking plate 22 corresponding to it. The distance between the paper blocking plate 22 and the first conveyor belt 11 is less than the height of the paper stack pushed onto the first conveyor belt. Further, the paper blocking plate 22 is connected to a lifting block 32. A rack 19 is connected to the lifting block 32. The rack 19 meshes with a gear 20. The gear 20 is connected to an adjusting shaft 21. The adjusting shaft 21 is in transmission connection with the output end of a driving motor 18. By controlling the driving motor 18 to start and drive the adjusting shaft 21 and the gear 20 to rotate, the lifting block 32 and the paper blocking plate 22 can be driven to lift and lower, and the distance between the paper blocking plate 22 and the first conveyor belt 11 can be adjusted. Corresponding to the rear side of the paper blocking plate 22, there is a paper pressing wheel 25. The paper pressing wheel 25 can elastically press the passing paper onto the first conveyor belt 11 for conveying. Specifically, the paper pressing wheel 25 is arranged on a wheel frame 24. One end of the wheel frame 24 is hinged to the cylinder body of a pressing cylinder 23. The cylinder body of the pressing cylinder 23 is slidably arranged on the machine frame, and its piston rod is hinged to the machine frame. By controlling the piston rod of the pressing cylinder 23 to extend, the wheel frame 24 can be driven to act so that the paper pressing wheel 25 elastically presses the paper onto the first conveyor belt 11. The discharge end of the first conveyor belt 11 is aligned with the paper feeding station of the die-cutting machine.Further, a pressing paper board 30 is provided below the paper lifting board 29 of the moving seat 4. The pressing paper board 30 is connected to a swing driving assembly. The swing driving assembly can be a swing block. The swing block is arranged on a rotating shaft. By controlling the rotation of the rotating shaft, the swing block and the pressing paper board 30 can be driven to swing. When pushing the paper, the pressing paper board 30 can swing to the top of the paper stack that has not been pushed on the lifting seat 1 to press the paper stack tightly on the lifting seat, ensuring that the papers that have not been pushed on the lifting seat 1 will not float or displace. Side paper aligning boards 9 are arranged on both sides of the feeding end of the first conveyor belt 11. The side paper aligning boards 9 are connected to a second moving driving assembly. The second moving driving assembly is a corresponding second air cylinder 10. By controlling the action of the second air cylinder 10, the side paper aligning boards 9 can be driven to act to align both sides of the paper stack. A paper pressing frame 16 is arranged on the front side of the paper blocking board 22. The paper pressing frame 16 is connected to a third lifting driving assembly. A paper pressing roller 15 is arranged on the paper pressing frame 16. The third lifting driving assembly is a third air cylinder 17. A rear paper aligning board 26 is arranged below the discharging end of the first conveyor belt 11. The rear paper aligning board 26 is connected to a third moving driving assembly. The third moving driving assembly can be a fourth air cylinder. The piston rod of the fourth air cylinder is connected to the rear paper aligning board 26. A second conveyor belt 2 is arranged on the lifting seat 1. A third conveyor belt 12 is arranged on one side corresponding to the lifting seat 1 descending to the bottom. A paper feeding roller 13 is arranged at the discharging end of the third conveyor belt 12. A pushing board 27 is arranged on one side of the paper feeding roller 13. The pushing board 27 can be connected to a corresponding second chain. The second chain bypasses a second sprocket. The second sprocket is connected to a corresponding pushing motor. By controlling the starting of the pushing motor, the pushing board 27 can be driven to act for paper pushing operation. A paper receiving platform 14 is arranged on one side of the pushing board 27.

[0022] The working principle of the present utility model is as follows: The paper is first stacked on the second conveyor belt 2 of the lifting seat 1. Then, the lifting seat 1 is controlled to rise to an appropriate height. Next, the moving seat 4 is controlled to move so that the paper lifting board 29 is inserted into the paper stack. Then, the paper lifting board 29 is controlled to lift some of the paper. At the same time, the paper pressing board 30 is controlled to swing to the top of the paper stack that has not been pushed. The moving seat 4 continues to move to push the lifted paper stack onto the first conveyor belt 11. The first conveyor belt 11 drives the paper stack to continue to be transferred to the side aligning paper board 9. By controlling the reciprocating movement of the side aligning paper board 9, the side of the paper stack is aligned. Then, the paper pressing frame 16 is controlled to descend, and the paper pressing roller 15 applies a certain downward pressure to the top of the stacked paper. The first conveyor belt 11 drives the paper stack to continue to move past the baffle plate 22. The baffle plate 22 will block the higher paper, so that the bottom paper is first moved under the drive of the first conveyor belt, and the subsequent paper partially covers the first moved paper, realizing the overlapping and sending of the paper in a covering and overlapping manner and successively stacking one by one at the paper feeding station. After sending out, the rear aligning paper board 26 is controlled to act to push the stacked paper and align the front and rear positions of the stacked paper. In addition, after the paper is pushed, there will be several pieces of paper on the second conveyor belt 2 of the lifting seat 1 that have not been pushed. At this time, the lifting seat 1 is controlled to descend to the bottommost position, and the second conveyor belt 2 acts to drive the paper through the third conveyor belt 12 to the paper feeding roller 13. Then, the pushing plate 27 is controlled to push the remaining several pieces of paper onto the receiving platform 14 for the worker to take away.

[0023] With this structure of the present utility model, the lifting, pushing, and overlapping and sending of the stacked paper one by one can be realized, and the whole process realizes automated operation, effectively reducing the labor intensity of workers and improving the pre-paper feeding efficiency and stability of the paper.
