Description

Technical Field

[0001] The utility model relates to the technical field of printing and binding, in particular to a punching device for book binding. Background Art

[0002] The binding of paper books is divided into two major processes: "mounting" and "stitching", which is a general term for the process of book processing. Among them, "mounting" is the processing of the book cover, that is, bookbinding, and "stitching" is the processing of the book block, that is, binding the pages into a book. The quality of binding will affect the reading, preservation of the book, and the final artistic effect presented.

[0003] However, in the prior art, the punching tools of traditional equipment usually use clamps for clamping. Therefore, after long-term use, when the tool wears or needs to be replaced due to production requirements, the tool cannot be quickly replaced, and only the clamp can be turned to replace the tool, thus increasing the working hours of the staff. In addition, because the traditional punching equipment does not have a pre-positioning device, when in use, the problem of book offset is likely to occur, resulting in hole position offset and affecting subsequent production.

[0024] Embodiment:

[0025] Please refer to Figure 1 - Figure 4 , the present utility model provides a technical solution: a punching device for bookbinding, comprising:

[0026] Frame 1;

[0027] Workbench 2, the bottom of the workbench 2 is fixedly connected to the inner wall of the bottom of the frame 1;

[0028] Hydraulic unit 6, the top of the hydraulic unit 6 is fixedly connected to the inner wall of the top of the frame 1;

[0029] Drilling mechanism 3, the top of the drilling mechanism 3 is fixedly connected to the bottom of the hydraulic unit 6;

[0030] Pre-positioning mechanism 4, the outer wall of the pre-positioning mechanism 4 is fixedly connected to the outer wall of the drilling mechanism 3;

[0031] Positioning pin 5, the top of the positioning pin 5 is fixedly connected to the inner wall of the drilling mechanism 3;

[0032] The punching mechanism 3 includes a cutting knife 31. A limiting block 32 is fixedly connected to the top of the cutting knife 31, and the limiting blocks 32 are annularly arrayed along the central axis of the cutting knife 31. A connecting block 36 is slidably connected to the outer wall of the limiting block 32. A rotating ring 34 is slidably connected to the inner wall of the connecting block 36. A clamping block 33 is fixedly connected to the inner wall of the rotating ring 34, and the clamping blocks 33 are annularly arrayed along the central axis of the rotating ring 34. The inner wall of the cutting knife 31 is fixedly connected to the top of the positioning pin 5. The top of the connecting block 36 is fixedly connected to the telescopic rod of the hydraulic unit 6. The telescopic rod in the hydraulic unit 6 drives the connecting block 36 to move up and down. A limiting column 35 is slidably connected to the inner wall of the rotating ring 34.

[0033] The outer wall of the limiting column 35 is slidably connected to the inner wall of the hydraulic unit 6 through a limiting groove 37, and the limiting groove 37 is formed in the wall of the hydraulic unit 6. By sliding the limiting column 35 into the limiting groove 37, the position of the rotating ring 34 is restricted. The inner wall of the connecting block 36 is slidably connected to the outer wall of the clamping block 33, and the outer wall of the clamping block 33 is slidably connected to the inner wall of the limiting block 32. The pre-positioning mechanism 4 includes a fixing plate 41. A limiting shell 43 is slidably connected to the bottom of the fixing plate 41 through a sliding plate 42, and the outer wall of the sliding plate 42 is slidably connected to the inner wall of the limiting shell 43. A positioning plate 44 is fixedly connected to the bottom of the limiting shell 43. A top spring 45 is fixedly connected to the outer wall of the positioning plate 44 through a support plate 46, and the outer wall of the support plate 46 is fixedly connected to the outer wall of the positioning plate 44.

[0034] One end of the top spring 45 away from the positioning plate 44 is fixedly connected to the bottom of the fixing plate 41, and the bottom of the top spring 45 is fixedly connected to the top of the support plate 46. One side of the fixing plate 41 away from the top spring 45 is fixedly connected to the outer wall of the connecting block 36. By pushing the support plate 46 with the top spring 45, the positioning plate 44 has a downward force. The bottom of the fixing plate 41 is fixedly connected to the top of the sliding plate 42.

[0035] Working principle:

[0036] During use, first place the frame 1 on the ground. After the position of the frame 1 is stabilized, the book to be punched can be placed on the workbench 2. Then start the hydraulic unit 6, and use the hydraulic unit 6 to drive the punching mechanism 3 to move downward, so as to punch the book. During the downward movement of the punching mechanism 3, the pre-positioning mechanisms 4 on both sides are synchronously driven to move downward. Since the position of the pre-positioning mechanism 4 is lower than that of the punching mechanism 3, the pre-positioning mechanism 4 contacts the book earlier than the punching mechanism 3 and presses on the book, so as to perform the pre-positioning work on the book. After the position of the book is determined by the pre-positioning mechanism 4, the staff can stop the downward movement of the hydraulic unit 6, and then observe whether the position of the book has shifted. If the position of the book has shifted, the hydraulic unit 6 can be started in reverse to make the pre-positioning mechanism 4 move upward. After the pre-positioning mechanism 4 moves away from the book, the position of the book can be adjusted, and then the hydraulic unit 6 can be started to move downward to start the pre-positioning and punching work; if the position of the book has not shifted, the hydraulic unit 6 can be continued to be started to make the punching mechanism 3 press on the book to perform the punching work.

[0037] When the punching mechanism 3 punches the book, the cutting knife 31 in the punching mechanism 3 cuts the book, and the positioning pin 5 in the cutting knife 31 is nailed into the cut paper, so as to take out the cut paper from the book. After the punching work is completed, the staff needs to take out the paper in the cutting knife 31 to perform the next punching work. Since the positioning pin 5 is set to be conical, it is convenient for the staff to take out the paper from the positioning pin 5. After long-term punching work or due to production requirements, when the cutting knife 31 needs to be replaced, the cutting knife 31 can be removed by rotating the rotating ring 34 on the connecting block 36.

[0038] First, slide the limiting column 35 out of the limiting groove 37 to release the locking of the rotating ring 34. Then rotate the rotating ring 34, and drive the clamping block 33 to slide in the connecting block 36 through the rotating ring 34. During the sliding process of the clamping block 33, it synchronously slides out of the groove on the limiting block 32. After the clamping block 33 completely slides out of the limiting block 32, the locking of the limiting block 32 is released. Then take out the cutting knife 31 from the connecting block 36, and align the new cutting knife 31 with the connecting block 36. It should be noted that during the installation of the new cutting knife 31, the limiting block 32 on the cutting knife 31 needs to be aligned with the groove on the connecting block 36. After the limiting block 32 slides into the connecting block 36, first keep the position of the cutting knife 31, and then rotate the rotating ring 34 in the reverse direction to make the clamping block 33 slide back into the limiting block 32 to lock the position of the cutting knife 31 again. Then slide the limiting column 35 back into the limiting groove 37 to lock the position of the rotating ring 34.

[0039] During the synchronous movement of the pre-positioning mechanism 4 and the punching mechanism 3, the positioning plate 44 contacts the book first, while the punching mechanism 3 is still moving downward, so the slide plate 42 continues to slide downward and slides into the limit shell 43 to maintain the position of the positioning plate 44. During the continuous downward movement of the fixed plate 41, the top spring 45 is synchronously compressed to allow the top spring 45 to accumulate elastic potential energy. After the punching mechanism 3 completes the punching work, the top spring 45 releases the elastic potential energy during the upward movement. Because the top spring 45 is connected to the positioning plate 44 through the support plate 46, the positioning plate 44 has a downward force, and the positioning plate 44 can be continuously pressed onto the book to prevent the book from shifting during the knife lifting process. As the fixed plate 41 continues to move upward, the positioning plate 44 is driven to separate from the surface of the book.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
