Abstract
Description
Technical Field
[0001] The invention relates to the technical field of printing equipment, in particular to a book clamp pressure maintaining mechanism for a perfect binder. Background Art
[0002] In the post-press binding process, one of the main factors affecting the quality of book formation is the clamping force of the book clamp on the book core. Specifically, the book clamp needs to ensure that the spine of the book core remains flat when passing through the milling station to facilitate the subsequent cover bonding. However, if the clamping force is unstable during the clamping of the book core, it may cause the book core to shift, affecting the flatness of the spine and further affecting the bonding effect of the cover. Especially when running at high speed or when the thickness of the book core is uneven, the book clamp may not be able to fully maintain the stability of the book core, resulting in displacement or deformation.
[0003] At present, perfect binding machines generally use compression springs, torsion springs or pneumatic systems to provide clamping force, but these traditional clamping force structures cannot completely prevent the book core from shifting (slipping) in the book clamp. Since the clamping force cannot be precisely adjusted, the book core may shift during the transmission process due to uneven clamping force, affecting the quality of the book. In addition, the number of clamping points of the book clamp is limited, and the clamping force cannot be evenly distributed, further increasing the risk of displacement. Summary of the invention

[0006] Preferably, the book clamping mechanism includes an inner clamping plate, which is slidably connected to the outside of the conveying mechanism, and an outer clamping plate is slidably connected to the middle of the inner clamping plate, one side of the outer clamping plate is connected to a mounting seat through positioning rods 2 and 1, and a guide wheel is rotatably connected to the outside of the mounting seat.
[0007] Preferably, the clamping force holding mechanism includes a side wall plate, the side wall plate is fixedly connected to the inner side of the conveying mechanism, the outer side of the side wall plate is fixedly connected to a mounting frame, the outer side of the mounting frame is fixedly connected to a mounting plate, one side of the mounting plate is slidably connected to a positioning seat, the bottom of the positioning seat is fixedly connected to a guide rod, and the guide wheel drives the outer clamping plate to move after contact with the guide rod.
[0008] Preferably, a traction chain and a positioning wheel are installed on the outer side of the inner clamping plate, the inner clamping plate is clamped on the guide rail of the conveying mechanism through the positioning wheel, and the inner clamping plate is connected to the driving disk of the conveying mechanism through the traction chain.
[0009] Preferably, a plurality of groups of springs are installed between the mounting seat and the inner clamping plate.
[0010] Preferably, the clamping force holding mechanism further comprises a guide wheel, which is rotatably connected to the top of the guide rod, and the guide wheel is in contact with the outer surface of the mounting frame, and when the guide rod moves, the guide wheel rolls on the outer side of the mounting frame.
[0011] Preferably, the clamping force adjustment mechanism includes a sliding shaft, which is slidably connected to the top of the mounting plate, a copper screw is rotatably connected to the outer side of the sliding shaft, an internal threaded sleeve is threadedly connected to one end of the outer side of the copper screw, and the other end of the internal threaded sleeve is fixedly connected to the outer side of the positioning seat, a driven wheel is fixedly connected to the outer side of the copper screw, a motor is fixedly connected to the top of the mounting plate, a driving wheel is fixedly connected to the output end of the motor, and a transmission chain is provided on the outer peripheral sleeves of the driving wheel and the driven wheel.
[0012] Preferably, a clamping seat is installed on the outer side of the sliding shaft, and a pressure wheel is rotatably connected to the end of the clamping seat, and the pressure wheel abuts against the outer side of the transmission chain.
[0013] Preferably, a plurality of tension springs are installed between the internal threaded sleeve and the positioning seat.
[0014] Preferably, a book-wrapping platform is installed in the outer shell of the conveying mechanism, a cover is placed on the upper part of the book-wrapping platform, and the book block is glued and bound at the position of the book-wrapping platform.
[0015] Working principle: The transmission mechanism cooperates with the traction chain to drive the book clamping mechanism to move as a whole. At this time, the positioning wheel is connected with the guide rail of the transmission mechanism to ensure the stability of the overall movement of the book clamping mechanism. Then, after the book core is placed between the inner and outer clamping plates, the cover is placed on the surface of the book wrapping table. At this time, the outer clamping plate is driven by the spring to approach the inner clamping plate, so as to achieve the initial clamping of the book core. When the book clamping mechanism moves to the wrapping table position as a whole, the guide rod enters between the mounting seat and the inner clamping plate. Under the continuous movement of the book clamping mechanism, the guide wheel contacts the side of the guide rod and moves along the outer surface of the guide rod under the influence of the notch on the side of the guide rod. At this time, affected by the shape of the guide rod, the guide wheel is pushed toward the mounting frame and the mounting seat is driven to move together. The outer clamping plate is pulled by the guide wheel and the mounting seat and moves toward the mounting seat, so as to reduce the distance between the inner and outer clamping plates, thereby completing the clamping of the book core to ensure the stability of the book core clamping.
[0016] Secondly, the driving motor can drive the active wheel to rotate, and the driven wheel can be driven to rotate under the action of the transmission chain, thereby making the copper screw tube rotate synchronously. At this time, the internal threaded sleeve can move back and forth through the thread between it and the copper screw tube, thereby driving the positioning seat and the guide rod to move together, so as to adjust the initial position of the guide rod, and cooperate with the book clamping mechanism to realize the adjustment of the clamping force of the book clamp.
[0017] The present invention provides a book clamp pressure maintaining mechanism for a perfect binder, which has the following beneficial effects:
[0018] 1. The present invention uses a guide rod to cooperate with a guide wheel to change the distance between the outer clamping plate and the inner clamping plate, thereby completing the clamping of the book core, and adjusting the clamping force of the book core by changing the position of the guide rod, thereby adapting to the clamping of book cores of different thicknesses, and the clamping force is controllable, avoiding the occurrence of unstable clamping and excessive clamping force.
[0019] 2. The present invention assembles multiple sets of tension springs between the internal thread sleeve and the positioning seat to achieve buffering and retention of the clamping force, further improving the clamping effect on the book block. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0028] Example:
[0029] Please see attached Figure 1 -Attached Figure 2 The embodiment of the present invention provides a book clamp pressure maintaining mechanism for a binder, including a conveying mechanism 1, a book binding table 4 is installed in the outer shell of the conveying mechanism 1, a cover is placed on the upper part of the book binding table 4, and the book core is glued at the binding table 4. A book clamping mechanism 2 for clamping the book core is installed on the outer side of the conveying mechanism 1, and the book core is clamped by the book clamping mechanism 2 and transported to the top of the binding table 4 for glue stapling.
[0030] Please see attached Figure 2 -Attached Figure 3 The book clamping mechanism 2 includes an inner clamping plate 21, which is slidably connected to the outer side of the transmission mechanism 1. The middle part of the inner clamping plate 21 is slidably connected to the outer clamping plate 26. One side of the outer clamping plate 26 is connected to the mounting seat 24 through the second positioning rod 28 and the first positioning rod 25. By changing the position of the mounting seat 24, the outer clamping plate 26 can be driven to move, so that the distance between the inner clamping plate 21 and the outer clamping plate 26 is changed, thereby completing the clamping operation of the book block. The outer side of the mounting seat 24 is rotatably connected to the guide wheel 29, and the outer side of the inner clamping plate 21 is installed with a traction chain 22 and a positioning wheel 23. The inner clamping plate 21 is clamped on the guide rail of the transmission mechanism 1 through the positioning wheel 23. The inner clamping plate 21 is connected to the driving disk of the transmission mechanism 1 through the traction chain 22. When the transmission mechanism 1 is working, its driving disk rotates, thereby acting on the traction chain 22. At this time, the inner clamping plate 21 slides on the guide rail of the transmission mechanism 1 under the action of the positioning wheel 23. A plurality of springs 27 are installed between the mounting seat 24 and the inner clamping plate 21. The springs 27 act on the mounting seat 24 to change the distance between the inner clamping plate 21 and the mounting seat 24, assisting the inner clamping plate 21 and the outer clamping plate 26 in clamping the book block, and providing a reset operation after clamping.
[0031] Please see attached Figure 4 -Attached Figure 6The conveying mechanism 1 is internally provided with a clamping force holding mechanism 3 for cooperating with the book clamping mechanism 2 to achieve clamping force holding. The clamping force holding mechanism 3 includes a side wall plate 31, the side wall plate 31 is fixedly connected to the inner side of the conveying mechanism 1, a mounting frame 32 is fixedly connected to the outer side of the side wall plate 31, a mounting plate 33 is fixedly connected to the outer side of the mounting frame 32, a positioning seat 34 is slidably connected to one side of the mounting plate 33, a guide rod 35 is fixedly connected to the bottom of the positioning seat 34, and the guide wheel 29 drives the outer clamping plate 26 to move after contacting the guide rod 35. When the book clamping mechanism 2 moves to the position of the book wrapping platform 4, the guide wheel 29 can enter the outer side of the guide rod 35 under the action of the inclined surface at the end of the guide rod 35. At this time, the guide wheel 29 will act on the mounting seat 24, causing the position of the mounting seat 24 to change. At the same time, the outer clamping plate 26 moves synchronously along the direction of movement of the mounting seat 24, thereby changing the distance between the outer clamping plate 26 and the inner clamping plate 21 to realize the clamping operation of the book core, thereby facilitating the book core to be glued and bound.
[0032] Please see attached Figure 4 The clamping force holding mechanism 3 also includes a guide wheel 36, which is rotatably connected to the top of the guide rod 35. The guide wheel 36 contacts the outer surface of the mounting frame 32. When the guide rod 35 moves, the guide wheel 36 rolls on the outside of the mounting frame 32. The end of the guide rod 35 can be positioned by the guide wheel 36 to ensure the stability of the guide rod 35 when it moves.
[0033] Please see attached Figure 4 -Attached Figure 6 A clamping force adjusting mechanism 5 for adjusting the clamping force is installed on the outside of the clamping force holding mechanism 3. The clamping force adjusting mechanism 5 includes a sliding shaft 51. The sliding shaft 51 is slidably connected to the top of the mounting plate 33. A copper screw 52 is rotatably connected to the outside of the sliding shaft 51. An inner thread sleeve 53 is threadedly connected to one end of the outer side of the copper screw 52.

The driving wheel 56 and the driven wheel 57 are fixedly connected. The outer sleeve is provided with a transmission chain 58. When the clamping force of the book clamping mechanism 2 needs to be adjusted, the driving motor 55 only needs to be driven to drive the driving wheel 56 to rotate, and the driven wheel 57 is driven to rotate synchronously with the cooperation of the transmission chain 58. At this time, the copper screw tube 52 rotates, and the internal thread of the internal thread sleeve 53 is cooperated to drive the internal thread sleeve 53 to move, so that the position of the positioning seat 34 can be changed, and then the position of the guide rod 35 can be adjusted. The distance between the outer clamping plate 26 and the inner clamping plate 21 can be changed with the guide wheel 29, so as to complete the adjustment of the clamping force of the book clamping mechanism 2.
[0034] Please see attached Figure 4 -Attached Figure 5A clamping seat 59 is installed on the outside of the sliding shaft 51, and a pressure wheel 510 is rotatably connected to the end of the clamping seat 59. The pressure wheel 510 abuts against the outside of the transmission chain 58. The transmission chain 58 is tensioned and adjusted by the pressure wheel 510 to ensure the synchronous rotation of the driven wheel 57 and the driving wheel 56. Multiple sets of tension springs 54 are installed between the internal thread sleeve 53 and the positioning seat 34. The distance between the positioning seat 34 and the internal thread sleeve 53 is adjusted by the tension springs 54. While ensuring clamping, excessive clamping force is avoided to play a clamping buffer for the book block.
