Description

Technical Field

[0001] This utility model relates to the field of book printing, specifically to a sealing device for book printing. Background Technology

[0002] Book printing is a field with a long history and constantly evolving technology. From the earliest woodblock printing and movable type printing to modern offset and digital printing, book printing technology has undergone several revolutionary changes. With technological advancements and people's increasing pursuit of a better reading experience, the quality, efficiency, and environmental friendliness of book printing are constantly improving. In the entire book printing process, pre-press design, printing technology, and post-press processing are three key stages. Among them, post-press processing, as the final step in book printing, is crucial for improving the overall quality and appearance of the book.

[0003] Edge sealing is an important step in post-printing processing. The purpose of edge sealing is to protect the edges of books, preventing wear and tear that could affect their appearance and lifespan during use. In mechanical edge sealing technology, edge sealing equipment for book printing is one of the key pieces of equipment. Through automated and intelligent operation, this equipment can achieve fast and precise edge sealing of books, greatly improving production efficiency and quality.

[0004] For example, the Chinese authorized patent with publication number CN 221968154 U (A Book Printing Edge Sealing Equipment) describes an edge sealing device where a hydraulic cylinder is fixedly connected to the top of the main body, and a second pressure plate is fixedly connected to the lower end. A threaded rod is rotatably connected to the second pressure plate via a bearing, and the outer wall of the second pressure plate is fixedly connected to the worktable. This book printing edge sealing equipment, through the cooperation of the edge sealing mechanism and the hydraulic cylinder, uses a first motor to drive a first gear to rotate, a moving block to move a push plate, and the push plate to move a cutter. This eliminates the need for manual adjustment of the book's position, thereby improving book positioning accuracy and work efficiency.

[0005] While the aforementioned existing technology has the function of fixing paper during edge sealing, the pressure drive structure is a single thread structure, which can more precisely control the pressure distance, but also brings the problem of slow pressure speed, which increases the working time of the equipment before edge sealing and affects the edge sealing efficiency. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) In this utility model, during the pressing process, the edge sealing pressing and fixing assembly is first driven to press down by the first drive cylinder. Then, through the cooperation of the first drive motor, the first bevel gear, the second bevel gear, the transmission wheel, and the transmission belt, the threaded upright is rotated synchronously, thereby driving the edge sealing pressing and fixing assembly to press down precisely. This not only improves the pressing speed but also makes the pressing distance control more precise. It solves the problem that the pressing drive structure is a single thread structure, which leads to a slow pressing speed, increases the working time of the equipment before edge sealing, and affects the edge sealing efficiency.

[0016] (2) In this utility model, the glue coating unit uses a third drive cylinder to drive the glue coating brush to move forward so that it contacts the cutting surface, and then drives it to move left and right. At the same time, the external pumping structure pumps the sealing glue into the glue box through the glue inlet pipe. The glue penetrates into the glue coating brush and is evenly coated on the cutting surface of the paper. It can evenly coat the glue on the cutting surface of the paper, resulting in a good sealing effect and avoiding the sealing quality problem caused by uneven glue coating.

[0031] Fixed bearing plates 14 are fixed to the front and rear ends of both sides of the pressing fixed plate 12. A second drive motor 15 is installed at the rear end of the rear fixed bearing plate 14. A bidirectional threaded rod 16 is connected between the two fixed bearing plates 14 on each side along the output shaft end of the second drive motor 15. Sliding blocks 17 are threaded to the front and rear ends of the bidirectional threaded rod 16. A drive half block 18 is fixed to the outside of the sliding block 17.

[0032] Through the coordinated operation of the first drive cylinder 10 and the first drive motor 4, the rapid and precise pressing of the pressing fixing plate 12 is achieved, ensuring the paper is firmly fixed during the sealing and cutting process.

[0033] (3) Glue application unit 23:

[0034] A glue application unit 23 is provided at the rear end of the upper part of the support base plate 1, including a rear fixed upright plate 24, a third drive cylinder 25, a front drive component 26, a transverse sliding component 27, a glue tank 28, a glue brush 29, and a glue inlet pipe 30. The rear fixed upright plate 24 is welded and fixed to the support base plate 1, and the third drive cylinder 25 is installed at its rear end. The output rod end of the third drive cylinder 25 is connected to the front drive component 26. The front drive component 26 contains a motor and a threaded rod, which is the drive structure. The transverse sliding component 27 is slidably connected inside the front drive component 26. The threaded rod is threadedly connected to the transverse sliding component 27.

A glue inlet pipe 30 is connected to one side of the glue tank 28.

[0035] The cooperation of the third drive cylinder 25 and the transverse sliding part 27 enables the back-and-forth and left-and-right movements of the glue brush 29, ensuring that the glue is evenly coated on the cut surface of the paper, thus improving the quality and aesthetics of the sealing.

[0036] (4) Cutting tool 22:

[0037] A second drive cylinder 21 is installed at the center of the upper rear end of the fixed top plate 3. The output rod end of the cylinder is connected to the cutting tool 22, and the cutting tool 22 is driven to move downward through the second drive cylinder 21.

[0038] Working principle: The paper for printing books is placed on the upper end of the lower pad 20. The first drive cylinder 10 drives the lower pressing plate 12 to move downward. After moving a certain distance, the second drive motor 15 starts to work, driving the bidirectional threaded rod 16 to rotate, so that the two sliding blocks 17 on each side move synchronously towards the middle.

[0039] When approaching the paper, the first drive cylinder 10 stops working, and the second drive motor 15 works to drive the sliding block 17 to continue moving. The drive half block 18 is located at the front and rear ends of the threaded upright 9. The first drive motor 4 drives the first bevel gear 5 to rotate. Through the meshing connection between the first bevel gear 5 and the second bevel gear 6, it drives the transmission wheel 7 on one side to rotate. Then, through the transmission relationship of the transmission belt 8, it drives the transmission wheel 7 on the other side to rotate. The two threaded uprights 9 rotate synchronously, driving the edge sealing and pressing fixing assembly 11 to continue moving downward and pressing on the upper end of the paper.

[0040] The second drive cylinder 21 drives the cutting blade 22 downward to cut the paper, and then the cutting blade 22 is driven upward to reset. The third drive cylinder 25 drives the front drive component 26 forward. The motor inside the front drive component 26 drives the threaded rod to rotate, thereby causing the transverse sliding component 27 to slide, which makes the glue brush 29 move. At the same time, the external pumping structure pumps the sealing glue into the glue tank 28 through the glue inlet pipe 30. Then the glue seeps into the glue brush 29 and is applied to the cut surface of the paper used for printing books as the glue brush 29 moves left and right.
