Description

Technical Field

[0001] This invention relates to the field of book printing, and more particularly to a conveying device for book printing. Background Technology

[0002] In the book printing production process, the conveyor system is a key piece of equipment connecting printing, drying, cutting, and binding processes, and its performance directly affects the quality of printed materials and production efficiency.

[0003] Traditional book printing conveyor systems mostly use belt conveyors or roller conveyors, which are simple in structure and single in function. In particular, during the conveying process, vibration or deviation can easily cause misalignment of pages and damage to the cover, affecting the quality of the finished product. Moreover, during high-speed conveying, books are prone to shifting or piling up, requiring manual intervention to sort them, which increases labor intensity and reduces production efficiency. In addition, the ink on the surface of the printed books is not completely dry, and traditional equipment lacks an effective auxiliary drying or smoothing structure, which can easily cause the text to become blurred or smudged. Summary of the Invention

The end of the electromagnetic slide rod 12 away from the motor 11 is rotatably connected to the middle of the positioning fastener 13. When the motor 11 is started, the motor 11 powers the electromagnetic slide rod 12 and starts it up. The electromagnetic slider 22 slides on the electromagnetic slide rod 12, thereby driving the entire conveying mechanism 2 to move back and forth along the slide rail 9.

Through the gear 1 52 meshing with it, the gear 2 53 rotates, thereby driving the rack 1 513 to move up and down. The rack 1 513 drives the fixed block 2 512 to move through the sliding rod 511. Then, through the linkage of the adapter 1 57, adapter 2 59, adapter 3 510 and movable part 58, the push plate 514 moves inward or outward, realizing automatic clamping or release of books, ensuring that the books remain neat during the transmission process.

The outer wall of the movable member 58 away from the bearing plate 8 is rotatably connected to the outer wall of the fixing block 512 away from the bearing plate 8 through two adapters 510. The outer wall of the fixing block 512 near the bearing plate 8 is rotatably connected to the outer wall of the middle part of the two adapters 57 through two adapters 59. A push plate 514 is fixedly connected to the end of the movable member 58 near the bearing plate 8.

[0046] The adjustable blowing mechanism 6 includes four fixed fasteners 61 that are evenly fixed to the outer wall of the main board 21, four electric push rods 62 that are respectively fixed to the middle of the four fixed fasteners 61, and the same hollow frame plate 63 that is fixed to the top of the four electric push rods 62. Four air outlet plates 64 are evenly fixed to the inner wall of the hollow frame plate 63, and a wind assembly mechanism 65 is provided inside the hollow frame plate 63.

[0047] The wind unit mechanism 65 includes a 651 fixedly connected to the upper rear left side of the hollow frame plate 63, a pulley 652 fixedly connected to the output end of the 651, and a pulley 655 rotatably connected to the inner top wall of the front left side of the hollow frame plate 63. A pulley 654 is rotatably connected to the inner top wall of the front right side of the hollow frame plate 63, and a pulley 653 is rotatably connected to the inner top wall of the rear right side of the hollow frame plate 63. The upper outer wall of pulley 652 is connected to the upper outer wall of pulley 655 via a synchronous belt 659. The lower outer wall of pulley 652 is connected to the lower outer wall of pulley 653 via a synchronous belt 656. The upper outer wall of pulley 653 is connected to the upper outer wall of pulley 654 via a synchronous belt 657. The lower outer wall of pulley 654 is connected to the upper outer wall of pulley 655 via a synchronous belt 657. The outer wall of the inner part is connected to the lower outer wall of the fourth pulley 655 by the third synchronous belt 658. Fans 6510 are fixedly connected to the lower middle of the first pulley 652, the second pulley 653, the third pulley 654 and the fourth pulley 655. The adjustable blowing mechanism 6 is activated. The electric push rod 62 can adjust the height of the hollow frame plate 63. The motor 651 in the air assembly mechanism 65 drives the first pulley 652 to rotate. Through the first synchronous belt 656, the second synchronous belt 657, the third synchronous belt 658 and the fourth synchronous belt 659, the second pulley 653, the third pulley 654 and the fourth pulley 655 rotate synchronously, thereby driving the four fans 6510 to work simultaneously, generating a uniform airflow, which is blown onto the surface of the book through the air outlet plate 64 to achieve auxiliary drying and surface smoothing of the printed book.

[0048] Working Principle: When using this equipment, place it on the lower side of the middle of the book printing device, start the motor 11, and the motor 11 will power the electromagnetic slide rod 12 to start it. The electromagnetic slider 22 slides on the electromagnetic slide rod 12, thereby driving the entire conveying mechanism 2 to move back and forth along the slide rail 9. The books to be printed are placed on the carrier plate 8. The spring rod 7 plays a buffering and shock-absorbing role to prevent the books from being misaligned due to vibration during the conveying process. When the carrier plate 8 moves up and down through the spring rod 7, the rack 2 515 fixedly connected to its outer wall moves accordingly. Through the gear 1 52 meshing with it, the gear 2 53 rotates, which in turn drives the rack 1 513 to move up and down. The rack 1 513 drives the fixed block 2 512 to move through the sliding rod 511. Then, through the linkage of the adapter 1 57, adapter 2 59, adapter 3 510 and the moving part 58, the push plate 514 moves inward or outward. The system automatically clamps and releases books during transport, ensuring they remain neat and tidy. Simultaneously, the adjustable blowing mechanism 6 activates, and the electric push rod 62 adjusts the height of the hollow frame plate 63. The motor 651 in the air assembly mechanism 65 drives pulley 1 652 to rotate, which in turn drives pulleys 2 653 654 655 to rotate synchronously via synchronous belts 1 656, 2 657, 3 658, and 4 659. This, in turn, drives four fans 6510 to work simultaneously, generating a uniform airflow that is blown onto the book surface through the air outlet plate 64. This process assists in drying and smoothing the printed books, preventing ink smudging or blurred text. In summary, this device, through a combination of mechanical linkage and electrical control, achieves automatic book transport, sorting, clamping, and auxiliary drying and smoothing, significantly improving the automation level and production quality of book printing.
