Description

A book clamping and cover positioning mechanism for a perfect binding machine Technical Field

[0001] This utility model relates to the field of book binding equipment technology, and in particular to a book clamping and forming and cover positioning mechanism for a book binding machine. Background Technology

[0002] Existing book binding equipment clamping mechanisms suffer from insufficient cover positioning accuracy. For example, the vertical lifting clamping device disclosed in CN211892571U, although it achieves paper clamping through the cooperation of a sliding sleeve, lifting column, and clamping panel, has significant limitations in its clamping mechanism:

[0003] This device relies on the planar clamping action of the clamping panel to fix the paper, but lacks multi-dimensional positioning constraints on the cover during the clamping process. Specifically, this manifests as: lack of lateral positioning: the clamping panel only provides longitudinal clamping force and cannot apply adjustable limiting action to the sides of the cover, causing the paper to easily shift laterally during clamping; insufficient longitudinal positioning: the longitudinal position of the cover on the platform relies on manual alignment, lacking a mechanized pushing and positioning mechanism, affecting binding consistency; poor dynamic stability: the mechanical vibration generated by the clamping action can easily cause the not fully fixed cover to shift, resulting in misalignment of the spine binding.

[0004] The aforementioned defects result in insufficient paper positioning accuracy during the perfect binding process, requiring repeated adjustments and significantly reducing production efficiency and binding quality. Therefore, there is an urgent need for an integrated mechanism capable of achieving multi-directional precise cover positioning and simultaneously completing clamping and positioning actions to solve the problem of unstable perfect binding quality caused by the lack of positioning function in existing technologies. Summary of the Invention
