The lower die 7 is fixedly installed in the middle of the outer surface of the upper end of the base 1. A through hole 8 is opened on the upper outer surface of the lower die 7. Indentation grooves 9 are opened on the left and right sides of the outer surface of the upper end of the base 1.

[0026] The hydraulic rod 10 is fixedly installed in the middle of the outer surface of the upper end of the top plate 4. The number of the guide rings 11 and the guide rods 12 is two groups each. The two groups of guide rings 11 are opened on the left and right sides in the middle of the outer surface of the upper end of the top plate 4. The guide rod 12 penetrates through the guide ring 11; the lower outer surface of the piston rod in the hydraulic rod 10 is fixedly connected to the middle of the upper outer surface of the fixing plate 13. The two groups of guide rods 12 are fixedly installed on the left and right sides of the upper outer surface of the fixing plate 13. The outer wall of the guide rod 12 is slidably connected with the guide ring 11; the upper outer surface of the punching cylinder 16 is fixedly connected to the lower outer surface of the upper die 6. The outer wall of the punching cylinder 16 is inserted into the through hole 8; the compression spring 17, the movable plate 18 and the ejector rod 19 are all located inside the punching cylinder 16. The upper outer surface of the compression spring 17 is fixedly connected to the upper part of the inner cavity of the punching cylinder 16. The lower outer surface of the compression spring 17 is fixedly connected to the upper outer surface of the movable plate 18. The ejector rod 19 is fixedly installed on the lower outer surface of the movable plate 18; the outer wall of the movable plate 18 is slidably connected with the inner wall of the punching cylinder 16. The upper outer surface of the movable plate 18 is elastically connected to the upper end of the inner cavity of the punching cylinder 16 through the compression spring 17.

[0027] It should be noted that the present utility model is a paper product indentation and punching device, provided with an upper die 6 and a lower die 7. The upper die 6 and the lower die 7 can be customized according to the model of the paper product. Moreover, the positions of the through holes 8, the indentation grooves 9 and the punching assembly 15 are produced together with the upper die 6 and the lower die 7. By means of die stamping, it is convenient to perform indentation and punching on the paper product simultaneously, improving the processing efficiency. During operation, the paper product to be processed is placed on the outer surface of the upper end of the lower die 7, and the lifting assembly 5 drives the upper die 6 to descend. The hydraulic rod 10 drives the upper die 6 to descend. The upper die 6 slides along the guide ring 11 through the guide rod 12. The hydraulic rod 10 can drive the upper die 6 to descend. Through the cooperation of the indentation ridges 14 and the indentation grooves 9, the indentation treatment of the paper product is realized.

After being stamped, the waste enters the inside of the punching cylinder 16 and extrudes the ejector rod 19 at the bottom of the movable plate 18. The movable plate 18 squeezes the compression spring 17 inside the punching cylinder 16. When punching is completed, due to the reaction force of the compression spring 17, the movable plate 18 is driven to reset, and the movable plate 18 pushes the waste inside the punching cylinder 16 out into the groove 2. By providing the ejector rod 19, the contact area with the paper product can be reduced, and better discharging can be achieved.
