Description

Technical Field

[0001] The present invention relates to the technical field of book block conveying of a perfect binding machine, and particularly to a 6-opening and 8-opening book block conveying mechanism. Background Art

[0002] Existing perfect binding equipment is mainly for perfect binding books and periodicals. Only some perfect binding equipment is suitable for perfect binding 8-opening test papers, only some is suitable for perfect binding 6-opening test papers, and there is also perfect binding equipment only suitable for perfect binding books and periodicals. Moreover, the functions of these equipment are relatively single, that is, 6-opening test papers, 8-opening test papers, and books and periodicals cannot be completed by the same equipment. If a printing and binding enterprise wants to complete the perfect binding of different types of books, periodicals, and test papers, then this enterprise needs to repeatedly invest in different types of perfect binding equipment, which will cause duplicate investment and waste of resources. The mechanism that cannot complete the above-mentioned perfect binding work of books, periodicals, and test papers with one equipment is mainly the conveying and flipping mechanism. The existing method is to use a manipulator to first clamp, flip, lift, and push. The process is complex and requires multiple single-function equipment units to cooperate to send 6-opening and 8-opening test papers into the book clamping station of the perfect binding machine. Different specifications of books, periodicals, and test papers need to be clamped and conveyed by manipulators of different specifications. The equipment is complex and the manufacturing cost is high, which cannot meet the actual use requirements. Therefore, there is an urgent need for improved technology in the market to solve the above problems. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects, and provide a 6-opening and 8-opening book block conveying mechanism with reasonable structural design and low manufacturing cost, which can be applicable to the perfect binding work of various books, periodicals, and test papers. During the conveying movement process, it follows the movement trajectory of the chain to turn the book block into a vertical state and send it into the book clamping station of the perfect binding machine in the vertical state. The structure runs stably, reduces the process, improves the work efficiency, and can effectively solve the problems in the background art.

[0004] To achieve the above object, the present invention provides the following technical solution: A 6-opening and 8-opening book block conveying mechanism, including a frame, a circular track, a circular chain, a driving sprocket, a driven sprocket, and a clamping assembly.
