During the printing process, especially in the perfect binding of large-sized paper, vibrations can easily occur when multiple layers of paper are milled and roughened, causing the paper in the middle to slip, resulting in uneven bases and affecting the binding effect.
The paper is supported and fixed on three sides by a clamping mechanism and a pressing mechanism. Combined with a roughening wheel, glue tank and suction cover, the paper is stably fed by a clamping motor and a moving frame. A vacuum generator and lifting cylinder are used to ensure that the book cover is tightly attached.
This effectively prevents the relative movement of multiple layers of paper during the roughening process, ensuring the neatness of the paper base and improving the binding quality and effect.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing technology, and in particular to a binding mechanism for printing. Background Technology
[0002] Binding is the post-printing process of processing printed pages and booklets into a book, or organizing and binding documents and receipts into a book. Binding includes processes such as perfect binding and saddle stitching. Perfect binding is a printing and binding process that uses adhesive to bond the book block to the cover, without the need for wire or thread. Its core process includes collating, milling the spine, roughening, gluing, and covering the cover, and is fixed by using hot melt adhesive to penetrate the gaps between the pages.
[0003] Currently, in the perfect binding process of printed paper, the paper is generally placed vertically in a clamping structure, and then the vertically clamped paper is pushed to bond and fix the base of the paper with glue and hot melt adhesive. However, for large-sized paper binding, when milling and roughening the base of multiple layers of paper, the vibration may cause the paper in the middle position to slide, which may result in unevenness in the middle and sides of the base of multiple layers of paper, which may affect the overall binding effect.

A connecting rod is hinged between the sliding seat and the limit rod. A spring is provided on the lower side of the connecting rod for fixing to the sliding seat. Sliding strips are slidably connected to the ends of the two clamping plates that are close to each other. The upper end of each sliding strip is slidably connected to the bottom of the clamping plate.

[0010] Preferably, the frame has two parallel tracks on the front side, and the bottom of the moving frame is slidably connected to the upper side of the tracks. The deburring blade, glue tank and adsorption cover are all located between the two tracks.
[0011] Preferably, both sliding seats are slidably connected to the top position on one side of the movable frame, and the end of the spring away from the sliding seat is fixed inside the side of the movable frame.
[0012] Preferably, the other side of the movable frame has a groove for placing the paper to be bound, and the rear side of the movable frame has a support arm with a threaded hole that mates with the movable screw.

[0029] The present invention will be further described below with reference to the accompanying drawings:
[0030] like Figures 1-8As shown, a binding mechanism for printing includes a frame 1, a glue tank 6 fixed in the middle of the frame 1, a lifting hydraulic rod 7 at the lower end of the glue tank 6, a roughening blade 5 on one side of the glue tank 6, the frame 1 being rotatably connected to the roughening blade 5, a roughening motor 4 fixedly installed at the lower end of the roughening blade 5, an adsorption cover 8 on the other side of the glue tank 6, and also includes a clamping mechanism 2 and a pressing mechanism 3.
[0031] In this embodiment: the clamping mechanism 2 includes a movable frame 21, a movable screw 22 at the rear end of the movable frame 21, a movable motor 23 fixedly mounted at one end of the movable screw 22, two symmetrical clamping plates 24 at the top of the movable frame 21, three sliding frames 25 fixedly mounted at the bottom of each clamping plate 24, a clamping screw 27 at one end of each clamping plate 24, a clamping motor 26 fixedly mounted at the front end of the clamping screw 27, a groove for placing the paper to be bound on the other side of the movable frame 21, a support arm at the rear of the movable frame 21, and a threaded hole on the support arm that mates with the movable screw 22, the clamping screw 27 being rotatably connected to the movable frame 21, the fixed part of the clamping motor 26 being fixedly connected to the front end of the movable frame 21, each sliding frame 25 being slidably connected to the top of the movable frame 21, and two parallel tracks on the front side of the frame 1. The bottom of the movable frame 21 is slidably connected to the upper side of the track. The brushing wheel 5, glue tank 6, and suction cover 8 are all located between the two tracks. Both ends of the movable screw 22 are rotatably connected to the inside of the frame 1. The frame 1 has a sliding groove at the support arm position. The rotating part of the clamping motor 26 drives the clamping screw 27 to rotate. The clamping screw 27 drives the two clamping plates 24 to move closer to each other. At this time, the two clamping plates 24 clamp and fix the paper under the support of the sliding frame 25 at their respective bottoms. Then, the rotating part of the movable motor 23 drives the movable screw 22 to rotate. When the movable screw 22 rotates, the movable frame 21 moves along the track to the other side through the support arm. During this process, the movable frame 21 drives the two clamping plates 24 and the paper to be bound to pass through the top of the brushing wheel 5, glue tank 6, and suction cover 8 in sequence.
[0032] In this embodiment: the clamping mechanism 3 includes a clamping plate 31, with a limit rod 33 fixed to one end of the clamping plate 31. Sliding seats 35 are provided on both the front and rear sides of the upper end of the limit rod 33. A connecting rod 34 is hinged between the sliding seats 35 and the limit rod 33. A spring 36 is provided on the lower side of the connecting rod 34 for fixing to the sliding seats 35. Sliding strips 32 are slidably connected to the ends of the two clamping plates 24 that are close to each other. The upper end of each sliding strip 32 is slidably connected to the bottom of the clamping plate 31. The two sliding seats 35 are slidably connected to the top position of one side of the movable frame 21. The end of the spring 36 away from the sliding seat 35 is fixed to one side of the movable frame 21. Inside the side, by pulling the pressing plate 31 upward, the two connecting rods 34 drive their respective sliding seats 35 to move closer to each other and compress the spring 36 between the two sliding seats 35. Then, the multi-layered paper to be bound is placed under the pressing plate 31 and positioned between the two clamping plates 24. At this time, the pressing plate 31 is released, and the two sliding seats 35 move away from each other under the action of the two springs 36. The pressing plate 31 is pulled downward by the two connecting rods 34. At this time, the bottom of the pressing plate 31 abuts against the top of the multi-layered paper. At the same time, the clamping mechanism 2 clamps and fixes the paper on both sides.
[0033] In this embodiment: multiple glue rollers are rotatably connected to the top side inside the glue tank 6. A baffle for pushing the melted glue upward is provided on the lower side inside the glue tank 6. The telescopic part of the lifting hydraulic rod 7 passes through the bottom of the glue tank 6 and is fixedly connected to the bottom of the baffle. A vacuum generator 9 for evacuating air from its interior is fixed at the bottom of the adsorption hood 8. The adsorption hood 8 has a hollow structure inside, and an adsorption hole for adsorbing book covers is opened on the top of the adsorption hood 8. Lifting cylinders 10 are fixedly installed at the four corners of the adsorption hood 8. When the root of the multi-layer paper passes the roughening blade 5, the roughening motor 4 drives the roughening blade 5 to roughen the root of the multi-layer paper. Then, as the multi-layer paper moves past the top of the glue tank 6, it passes through... The glue is applied to the base of the multi-layered paper by the glue rollers inside the glue tank 6. During the glue application process, the partition can be moved upward by the telescopic part of the lifting hydraulic rod 7, which pushes the glue to the lower side of the multiple glue rollers. When the multi-layered paper passes the top of the glue tank 6, the book cover to be bound is laid on the top of the adsorption cover 8. The vacuum generator 9 evacuates the air inside the adsorption cover 8, so that the book cover is tightly attached to the top of the adsorption cover 8. When the moving frame 21 moves the multi-layered paper with glue applied to the top of the adsorption cover 8, the four lifting cylinders 10 push the adsorption cover 8 upward by the telescopic part, so that the middle position of the book cover at the top of the adsorption cover 8 is attached to the base of the multi-layered paper.
[0034] Working principle: In use, firstly, by pulling the pressure plate 31 upward, the two connecting rods 34 drive their corresponding sliding seats 35 to move closer together, compressing the spring 36 between the two sliding seats 35. Then, the multi-layered paper to be bound is placed under the pressure plate 31 and positioned between the two clamping plates 24. At this point, the pressure plate 31 is released, and the two sliding seats 35 move away from each other under the action of the two springs 36. The two connecting rods 34 pull the pressure plate 31 downward, at which point the bottom of the pressure plate 31 rests against the top of the multi-layered paper. Simultaneously, the rotating part of the clamping motor 26 drives the clamping screw 27 to rotate, which in turn drives the two clamping plates 24 to move closer together. At this point, the two clamping plates 24 clamp and fix the paper under the support of their respective sliding frames 25. Then, the rotating part of the moving motor 23 drives the moving screw 22 to rotate. When the moving screw 22 rotates, it drives the moving frame 21 to move along the track to the other side through the support arm. During this process, the moving frame... 21 drives two clamping plates 24 and the paper to be bound to pass sequentially through the top of the roughening wheel 5, glue tank 6, and suction cover 8. When the root of the multi-layered paper passes the roughening wheel 5, the roughening motor 4 drives the roughening wheel 5 to roughen the root of the multi-layered paper. Then, as the multi-layered paper moves, it passes the top of the glue tank 6, where the glue roller inside the glue tank 6 applies glue to the root of the multi-layered paper. In addition, during the glue application process, the partition can be pushed upward by the telescopic part of the lifting hydraulic rod 7, thereby making the partition... The movement of the plate pushes the glue to the lower side of multiple glue rollers. When the multi-layered paper passes the top of the glue tank 6, the book cover to be bound is laid on the top of the adsorption cover 8. The vacuum generator 9 evacuates the air inside the adsorption cover 8, so that the book cover is tightly attached to the top of the adsorption cover 8. When the moving frame 21 moves the multi-layered paper with glue applied to it to the top of the adsorption cover 8, the four lifting cylinders 10 push the adsorption cover 8 upward through their telescopic parts, so that the middle position of the book cover at the top of the adsorption cover 8 is attached to the root of the multi-layered paper.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
