[0013] Figure 2 It is a structural diagram of the push paper board of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] As shown in the figure, the semi-automatic pre-feeding mechanism of the die-cutting machine disclosed by the present utility model includes a lifting seat 9 for stacking paper. The lifting seat 9 is connected to a lifting drive assembly. Specifically, the lifting drive assembly includes a first motor 1. The output end of the first motor 1 is connected to a sprocket 2. A chain is wound around the sprocket 2, and the chain is connected to the lifting seat 9. By controlling the first motor 1 to drive the sprocket 2 to rotate, and then driving the chain 2 to move, the lifting seat 9 can be driven to lift and lower. A push paper board is arranged above the lifting seat 9. In this embodiment, the push paper board is L-shaped, having a horizontally arranged top plate portion 7 and a side plate portion 8. The top plate portion 7 can contact the top surface of the stacked paper, which can ensure that the rear side of the stacked paper will not float upward during the pushing process. The side plate portion 8 abuts against the rear side of the stacked paper. The push paper board is connected to a moving drive assembly. Specifically, the moving drive assembly includes a first cylinder 6. The cylinder body of the first cylinder 6 is connected to the push paper board, and the piston rod of the first cylinder 6 is connected to a fixedly arranged frame plate 3. A guide post 4 is also arranged on the frame plate 3. The guide post 4 passes through a guide seat 5 on the push paper board. By controlling the first cylinder 6 to act, the push paper board can be driven to act. A paper guide frame 15 is arranged on one side of the push paper board. Paper guide rollers 16 are arranged on the paper guide frame 15. The paper guide frame 15 is movably arranged on the bottom frame 12. The feeding end of the paper guide frame 15 is slightly higher than the discharging end. The paper guide frame 15 is connected to a swing adjustment assembly. The discharging end of the paper guide frame 15 is aligned with the paper feeding station of the die-cutting machine. Specifically, the feeding end of the paper guide frame 15 is rotatably arranged on a first lifting column 11, and the discharging end of the paper guide frame 15 is rotatably arranged on a second lifting column 13. The first and second lifting columns are slidably arranged on the bottom frame 12. The swing adjustment assembly includes a first adjustment screw 10 and a second adjustment screw 14. The bottom of the feeding end of the paper guide frame 15 abuts against the first adjustment screw 10, and the bottom of the discharging end of the paper guide frame 15 abuts against the second adjustment screw 14. The first and second adjustment screws are screwed on the bottom frame 12. By controlling the first and second adjustment screws to rotate for lifting and lowering, the heights of both ends of the paper guide frame 15 can be adjusted, and thus the swing angle of the paper guide frame 15 can be adjusted, so that the feeding end of the paper guide frame 15 is slightly higher than the discharging end.

[0015] The working principle of the present utility model is as follows: Stack the paper on the lifting seat 9, then control the lifting seat 9 to drive the paper stack to rise to an appropriate height, and then control the push paper board to act to push the paper on the lifting seat 9 away from the lifting seat. The pushed paper then falls onto the paper guide rollers 16 on the paper guide frame 15 and gradually descends under the guidance of the paper guide rollers 16. At this time, only manual assistance is required to send the paper to the paper feeding station for stacking to complete the pre-feeding operation.

[0016] With this structure of the utility model, by setting up a moving drive assembly to drive the paper pushing board to move, the stacked papers can be pushed on the lifting seat, and in cooperation with the paper guiding frame and paper guiding rollers arranged, the pushed papers can be guided and transferred. The operator only needs to assist in feeding the papers conveyed on the paper guiding frame into the paper feeding station, which can greatly reduce the labor intensity of the operator and improve the overall pre-paper feeding efficiency.
