[0002] The perfect binding production line is an automated mechanical equipment system, which is mainly used to bond printed paper or paper products together through adhesives to form finished products such as books, magazines, brochures, etc. Perfect binding is a common book binding method, which is widely used in publishing and printing industries due to its high production efficiency and good binding quality.

[0003] For example, a binding and book trimming machine disclosed in Chinese patent announcement number (CN210101094U) relates to the technical field of packaging and printing equipment, which includes a spiral conveyor belt, a binder and a three-sided book trimmer. The input end of the spiral conveyor belt is connected to the book outlet of the binder. A cooling box that completely covers the spiral conveyor belt is arranged on the outside of the spiral conveyor belt. A cold air fan with an air outlet extending into the cooling box is fixed on the outside of the cooling box. The end of the spiral conveyor belt away from the binder is higher than the upper book table of the three-sided book trimmer and a second conveyor belt is arranged below the end. The end of the second conveyor belt away from the spiral conveyor belt is connected to the upper book table of the three-sided book trimmer, and the other end is provided with a book stacking device for stacking bound books in a fixed number.

[0015] By adopting this technical solution, friction is reduced, so that the sliding of the adjustment frame on the crossbeam is smoother, and the flexibility and efficiency of adjustment are improved.

[0016] Furthermore, screw holes are provided on the upper surfaces of the four adjustment frames, and the inner walls of the four screw holes are threadedly connected with locking bolts, and handles are fixed to the top ends of the four locking bolts.

[0017] By adopting this technical solution, a method for quickly adjusting and fixing the limiting mechanism is provided, making the operation simpler and faster, and the handle design at the top of the locking bolt allows the operator to easily adjust and fix.

[0020] Furthermore, a plurality of the rotating shafts are evenly distributed along the length direction of the two guide plates.

[0021] By adopting this technical solution, the guide roller can evenly support and guide the books, thereby improving the stability and efficiency of transportation.

[0022] Furthermore, the left side of the buffer pad and the left side of the guide plate are located in the same horizontal plane, and the outer side of the guide roller and the side of the buffer pad facing away from the guide plate are located in the same horizontal plane.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0034] See also Figure 1 In this embodiment, a binding production line has an adjustable material limiting mechanism, including a binding conveyor belt 1, a limiting mechanism 2 is provided on the front and rear sides of the upper surface of the binding conveyor belt 1, and a protective mechanism 3 is provided on the side opposite to the limiting mechanism 2.

[0035] See also Figures 2 to 4In order to adjust the conveying limit of book binding, the limiting mechanism 2 in this embodiment includes four fixed frames 21, two cross beams 22, four adjustment frames 23, two limiting plates 24 and a guide 25. Before the binding production line starts working, the limiting mechanism 2 is adjusted and set accordingly according to the size and thickness of the books to be bound. The four fixed frames 21 are respectively fixed to the front and rear sides of the upper surface of the binding conveyor belt 1, the two cross beams 22 are respectively fixed to the upper surfaces of the fixed frames 21 on the front and rear sides, the four adjustment frames 23 are respectively slidably arranged on the outer sides of the two cross beams 22, the tops of the two limiting plates 24 are respectively rotatably connected to the bottoms of the adjusting frames 23 on the front and rear sides, and the guide 25 is arranged between the upper and lower inner walls of the two limiting plates 24 to facilitate the adjustment of the guiding opening and closing angle.

[0036] The guide member 25 includes two connecting shafts 251, two guide plates 252, two supporting springs 253 and four locking plates 254. The two connecting shafts 251 are respectively fixed between the inner walls of the upper and lower sides of the two limiting plates 24. The two guide plates 252 are respectively rotatably connected to the outer sides of the two connecting shafts 251. The operator prepares to adjust the guide member 25 to adapt to books of different sizes and slides the two locking plates 254 to move in relative directions, so that the latching teeth 255 on the locking plates 254 are separated from the latching grooves on the guide plates 252. The two supporting springs 253 are respectively movably mounted on the outer sides of the two connecting shafts 251, and the two ends of the two supporting springs 253 are respectively fixed to the four locking plates 254. After the latching teeth 255 are separated, the guide plate 252 can rotate freely along the outer side of the connecting shaft 251 without being restricted by the latching teeth 255. The operator changes the opening and closing angle between the guide plate 252 and the limiting plate 24 by rotating it, so as to guide books of different sizes to enter between the limiting plates 24 smoothly.

[0037] In this embodiment, a plurality of latch teeth 255 are fixed in an annular shape on one side of the locking plate 254 facing away from the supporting spring 253. The guide plate 252 is in a U-shape, and the inner walls on the upper and lower sides of the guide plate 252 are provided with latch grooves corresponding to the positions of the plurality of latch teeth 255. After adjusting to the appropriate position, the operator releases the locking plate 254, and the rebound force of the supporting spring 253 causes the latch teeth 255 to be reinserted into the latch grooves on the guide plate 252. The elastic force of the supporting spring 253 supports the guide plate 252 through the locking plate 254, so that it stably abuts against the inner wall of the limiting plate 24, preventing the guide plate 252 from being stuck. 2 is rotated to ensure the stability after adjustment. The lower surface of the adjustment frame 23 and the left and right sides of the cross beam 22 are rotatably connected with rollers. The upper surface of the locking plate 254 is provided with a sliding hole, and the locking plate 254 is slidably connected to the outer side of the connecting shaft 251 through the sliding hole. The upper surfaces of the four adjustment frames 23 are provided with screw holes, and the inner walls of the four screw holes are threadedly connected with locking bolts 26. The tops of the four locking bolts 26 are fixed with handles 27. The operator adjusts the position of the adjustment frame 23 by the locking bolts 26 and the handles 27, so that the two limiting plates 24 are tapered to accommodate books of different widths.

[0038] It should be noted that after the adjustment is completed, the book can be smoothly guided between the two limiting plates 24 of the limiting mechanism 2 to proceed to the next step of the binding process. When in use, the book is placed on the binding conveyor belt 1, and the limiting mechanism 2 begins to work to ensure the stability and centering of the book during the conveying process. During the book conveying process, if necessary, the operator can further fine-tune the limiting mechanism 2 to cope with slight changes in the book size.

[0039] See also Figure 5 In order to reduce the damage of the book during the material limiting adjustment, the protection mechanism 3 in this embodiment includes two buffer pads 31, two connecting frames 32, a plurality of rotating shafts 33 and a plurality of guide rollers 34. The two buffer pads 31 are respectively fixed to the opposite side of the two guide plates 252. When the book moves on the binding conveyor belt 1 and enters between the two guide plates 252, the edge of the book first contacts the buffer pad 31. The function of the buffer pad 31 is to absorb the impact force to prevent the book from being damaged due to direct impact when entering the limiting mechanism 2. The two connecting frames 32 are respectively fixed to the opposite side of the two guide plates 252 and located on the right side of the buffer pad 31. The plurality of rotating shafts 33 are respectively rotatably connected between the upper and lower inner walls of the two connecting frames 32 through bearings. The plurality of guide rollers 34 are respectively fixed to the outer sides of the plurality of rotating shafts 33. As the book continues to move forward, the guide rollers 34 rotate with the rotating shafts 33. These guide rollers 34 help guide and stabilize the transportation of the book, reducing the possible deviation of the book during the transportation process.

[0040] In this embodiment, a plurality of rotating shafts 33 are evenly distributed along the length direction of the two guide plates 252. The rotation of the guide roller 34 can reduce friction, improve the conveying efficiency of books, ensure that books pass through the limiting mechanism smoothly, help integrate the books into the path set by the limiting mechanism 2, and ensure the accurate alignment of the books during the binding process. The left side of the buffer pad 31 is located on the same horizontal plane as the left side of the guide plate 252, and the outer side of the guide roller 34 is located on the same horizontal plane as the side of the buffer pad 31 facing away from the guide plate 252.

[0041] The working principle of the above embodiment is:

[0042] (1) Before the binding production line starts working, the limiting mechanism 2 is adjusted and set accordingly according to the size and thickness of the books to be bound. The operator adjusts the position of the adjustment frame 23 by tightening the bolt 26 and the handle 27 so that the two limiting plates 24 close in a conical shape to accommodate books of different widths. The operator prepares to adjust the guide member 25 to accommodate books of different sizes. The two locking plates 254 are slid to move in opposite directions, so that the locking teeth 255 on the locking plates 254 are separated from the locking grooves on the guide plates 252. After the locking teeth 255 are separated, the guide plates 252 can rotate freely along the outer side of the connecting shaft 251 without being restricted by the locking teeth 255. The operator rotates the guide plates 252 to change the opening and closing angle between them and the limiting plates 24, so as to guide books of different sizes to be smoothly loaded. After entering between the limiting plates 24 and adjusting to the appropriate position, the operator releases the locking plate 254, and the rebound force of the support spring 253 causes the latch tooth 255 to be reinserted into the slot on the guide plate 252. The elastic force of the support spring 253 supports the guide plate 252 through the locking plate 254, so that it is stably abutted against the inner wall of the limiting plate 24 to prevent the guide plate 252 from rotating, thereby ensuring the stability after adjustment. After the adjustment is completed, the book can be smoothly guided into between the two limiting plates 24 of the limiting mechanism 2 to proceed to the next step of the binding process. When in use, the book is placed on the binding conveyor belt 1, and the limiting mechanism 2 begins to work to ensure the stability and centering of the book during the conveying process. During the book conveying process, if necessary, the operator can further fine-tune the limiting mechanism 2 to cope with slight changes in the book size.

[0043] (2) When a book moves on the binding conveyor belt 1 and enters between the two guide plates 252, the edge of the book first contacts the buffer pad 31. The buffer pad 31 is used to absorb impact force and prevent the book from being damaged due to direct impact when entering the limiting mechanism 2. As the book continues to move forward, the guide rollers 34 rotate with the rotating shaft 33. These guide rollers 34 help guide and stabilize the conveyance of the book and reduce the possible deviation of the book during the conveyance process. The rotation of the guide rollers 34 can reduce friction, improve the conveyance efficiency of the book, ensure that the book passes through the limiting mechanism smoothly, and help integrate the book into the path set by the limiting mechanism 2 to ensure the accurate alignment of the book during the binding process.
