[0025] Please refer to Figures 1-5. This utility model provides a technical solution: a paper printing binding device, including: a base 1, a positioning device 2 fixedly connected to the outer wall of the top of the base 1, and a punching device 3 slidably connected to the inner wall of the top of the base 1; the punching device 3 includes a support plate 31, a hydraulic rod 32 fixedly connected to the outer wall of the top of the support plate 31, a support frame 33 fixedly connected to the outer wall of the bottom of the hydraulic rod 32, a connecting plate 34 symmetrically fixedly connected to the outer wall of the side of the support frame 33, a sliding rod 35 slidably connected to the inner wall of the connecting plate 34, a pressure plate 36 fixedly connected to the outer wall of the bottom of the sliding rod 35, a pressure spring 37 fixedly connected to the outer wall of the pressure plate 36, a limit groove 331 opened on the outer wall of the support frame 33, a rotating shaft 38 rotatably connected to the inner wall of the support frame 33, a spring buckle 381 fixedly connected to the outer wall of the rotating shaft 38, and a punching head 39 fixedly connected to the outer wall of the rotating shaft 38.

[0026] The outer wall of the pressure spring 37 on the side away from the pressure plate 36 is fixedly connected to the outer wall of the bottom of the connecting plate 34. The limiting groove 331 is arranged in a ring along the central point of the rotating shaft 38. The outer wall of the spring buckle 381 is in contact with the inner wall of the limiting groove 331. The punching heads 39 are arranged in a ring along the central point of the rotating shaft 38, and the size of the punching heads 39 is different.

[0027] An adjustment groove 11 is provided on the outer wall of the top of the base 1, and an adjustment threaded rod 12 is rotatably connected to the inner wall of the adjustment groove 11.

[0028] The outer wall of the bottom of the support plate 31 is slidably connected to the inner wall of the adjustment groove 11, and the inner wall of the bottom of the support plate 31 is threadedly connected to the outer wall of the adjustment threaded rod 12. Rotating the adjustment threaded rod 12 can make the support plate 31 slide in the adjustment groove 11, thereby adjusting the position of the punching device 3 relative to the positioning device 2.

[0029] The positioning device 2 includes a positioning seat 21. The outer wall of the top of the positioning seat 21 is provided with a clamping groove 22 and a positioning groove 25. The inner wall of the clamping groove 22 is rotatably connected to a bidirectional threaded rod 23. The outer wall of the bidirectional threaded rod 23 is threadedly connected to a clamping plate 24. The inner wall of the positioning groove 25 is rotatably connected to a positioning threaded rod 26. The outer wall of the positioning threaded rod 26 is threadedly connected to a positioning plate 27.

[0030] The outer wall of the clamping plate 24 is slidably connected to the inner wall of the clamping groove 22. By rotating the bidirectional threaded rod 23 in the clamping groove 22, the clamping plate 24 will slide on the inner wall of the clamping groove 22 due to the threaded connection between the bidirectional threaded rod 23 and the clamping plate 24, thereby achieving the clamping and fixing of the paper at the front and back. The outer wall of the positioning plate 27 is slidably connected to the inner wall of the positioning groove 25. By rotating the positioning threaded rod 26 in the positioning groove 25, the positioning plate 27 slides on the inner wall of the positioning groove 25 to position the side position of the paper. The outer wall of the positioning seat 21 is slidably connected to the outer wall of the support plate 31. A punching hole is opened on the outer wall of the top of the positioning seat 21. The inner wall of the punching hole on the top of the positioning seat 21 is slidably connected to the outer wall of the punching head 39.

[0031] When in use, place the paper printed materials to be bound on the positioning device 2 for initial positioning to prevent the printed materials from shifting during binding and punching. Then, the punching device 3 is used to bind and punch the positioned printed materials.

[0032] First, place the paper printed materials to be bound on the positioning seat 21. By rotating the bidirectional threaded rod 23 in the clamping groove 22, since the bidirectional threaded rod 23 is threadedly connected to the clamping plate 24, the clamping plate 24 will slide on the inner wall of the clamping groove 22, thereby clamping and fixing the paper from front to back, ensuring that the paper will not move back and forth during the binding process. At the same time, rotate the positioning threaded rod 26 in the positioning groove 25, and the positioning plate 27 will slide on the inner wall of the positioning groove 25 to position the side position of the paper, ensuring the accuracy of the paper punching position.

[0033] If it is necessary to adjust the position of the punching device 3, the adjusting threaded rod 12 in the adjusting groove 11 on the base 1 can be operated. Since the bottom of the support plate 31 is slidably connected to the inner wall of the adjusting groove 11 and threadedly connected to the adjusting threaded rod 12, rotating the adjusting threaded rod 12 can make the support plate 31 slide in the adjusting groove 11, thereby adjusting the position of the punching device 3 relative to the positioning device 2.

[0034] Once positioning is complete, hydraulic rod 32 is activated, pushing support frame 33 downwards. During this downward movement, pressure plate 36 first contacts the paper. Since pressure plate 36 is slidably connected to connecting plate 34 via slide rod 35 and pressure spring 37 connects pressure plate 36 and connecting plate 34, pressure plate 36 will initially press the paper down. As support frame 33 continues to descend, pressure spring 37 is compressed. Simultaneously, punch head 39 on support frame 33 also moves downwards, passing through the punch hole at the top of positioning seat 21 to perform a binding punching operation on the paper. Meanwhile, as punch head 39 moves along the axis of rotation 38... The ring array has different sizes, and the appropriate punch head 39 can be selected by rotating the rotating shaft 38 according to the actual binding needs. The spring buckle 381 on the rotating shaft 38 cooperates with the limiting groove 331 opened on the outer wall of the support frame 33. When it is necessary to switch the punch head 39, first pull the spring buckle 381 outward to make it slide away from the limiting groove 331, then rotate the rotating shaft 38 to the appropriate punch head 39 position, release the spring buckle 381, and the spring buckle 381 will lock into the limiting groove 331 to position the rotating shaft 38, ensuring that the position of the punch head 39 is stable during punching, thus completing the switching of the punch head 39.
