Description

Technical Field

[0001] This utility model relates to the field of perfect binding thread technology, specifically a novel book-separating and conveying device. Background Technology

[0002] Perfect binding is a binding method that uses adhesive to fix the pages of printed materials to the spine.

However, existing devices require manual placement of each book block onto the conveyor mechanism, lacking a dedicated device for separating and conveying stacked book blocks. Furthermore, existing devices are structurally complex, either failing to achieve automatic separation or lacking a handover structure between the conveyor and separation processes, resulting in poor separation efficiency.

This novel book-separating and conveying device has a simple structure and can automatically separate and convey stacked book blocks. It is suitable for book blocks of different thicknesses and can accurately achieve the handover between the book-separating and conveying mechanisms, saving significant manpower.

[0018] In use: First, when pushing different types of book blocks, the rotation of the adjusting shaft 583 can drive the guide wheel 582 to rotate. The rotation of the guide wheel 582 can drive the adjusting belt 584 to rotate. The rotation of the adjusting belt 584 can drive the adjustable support 572 to slide up and down along the support slide rail 573. The up and down sliding of the adjustable support 572 can drive the infrared detector 571 to move up and down. This can accommodate book blocks of different thicknesses. The second step is to place the stacked book blocks on the upper surface of the conveyor belt 510, and then drive the conveyor shaft 59 to rotate by the rotation of the book-separating conveyor motor 511. The rotation of the conveyor shaft 59 can drive the conveyor belt 510 to rotate, and the rotation of the conveyor belt 510 moves the stacked book blocks to one side of the infrared detector 571, and the infrared detector 571 detects the position of the upper end of the book blocks. Then, when the feeding motor 541 operates, the rotation of the adjusting sprocket and adjusting chain 542 drives the screw 1 544 to rotate. The rotation of the screw 1 544 drives the mounting base 543 to move up and down. The mounting base 543 drives the sliding connecting seat 512 to move up and down. The sliding connecting seat 512 drives the book support table 52 to adjust up and down, thereby driving the book core on the conveyor belt 510 to move up and down, thus adjusting the position of the book core to the position of the infrared detector 571. Turning the handwheel 564 drives the screw 2 563 to rotate. The screw 2 563 drives the sliding seat 562 to slide along the support track 561. The sliding of the movable seat 562 can drive the workpiece pushing assembly 55 to move, thereby adjusting the position of the workpiece pushing assembly 55. The extension of the vertical drive cylinder 552 can drive the push plate 551 to move to the lower end. The extension of the horizontal drive cylinder 553 can drive the push plate 551 to move. The push plate 551 can push the book core on the conveyor belt 510, thus pushing the upper end of the book core. When the workpiece pushing assembly 55 finishes pushing the upper end of the workpiece and returns to the initial position, the vertical adjustment assembly 54 can raise the upper end of the book core back to the detection position of the infrared detector 571. This process is repeated to push the book core into the transfer mechanism 6. When conveying book blocks of different thicknesses, the gap between the pressure roller 610 and the transfer conveyor belt 63 needs to be adjusted. This adjustment is achieved by rotating the adjusting nut 661, which in turn moves the screw 662 up and down. The screw 662 moves the sliding frame 64 up and down along the sliding track 62, which in turn moves the pressure roller 611 and the pressure roller 610 up and down. This adjusts the gap between the pressure roller 610 and the transfer conveyor belt 63, thus accommodating the production of books of different thicknesses. Then, the transmission assembly 67 drives a rotating shaft 633 on the transfer conveyor belt 63 to rotate, which in turn drives the conveyor belt 632 to rotate. The book block is conveyed to the upper right side of the scraping assembly 7 by the rotation of the conveyor belt 632. The book block is scraped by the conveyor scraper 621 on the scraping assembly 7. When the rotating shaft 633 rotates, it drives the gear 681 to rotate. Then, through the transmission of the gear 682, the rotating shaft 633 and the universal joint 613, it drives the pressure roller 611 to rotate. The rotation of the pressure roller 611 drives the pressure wheel 610 to rotate. The pressure wheel 610 and the conveyor belt 632 can convey the book block, making the conveying more convenient. When the scraping motor 2 is running, it drives the conveyor main shaft and the drive sprocket 4 to rotate through the transmission assembly 3. The drive sprocket 4 drives the conveyor chain 72 to rotate. The book block is scraped by the conveyor scraper 71.
