Buffering positioning device of book sewing machine

Abstract

The invention relates to book binding equipment, in particular to a buffering and positioning mechanism of a book sewing machine which comprises a slope track, a book placing board and a pull rod fixed on the frame of the book sewing machine, and a fixing seat, a block track, at least a making leaf spring and a buffer groove block fixed on the book placing board. The pull rod movably supports the book placing board and can move transversally; one end of the pull rod is in contact with the slope track in a sliding manner; a spring is arranged on the pull rod; a guiding plate is arranged at one end of the block track; the block track moves through the guiding plate along the guiding groove in the fixing seat; the other end of the block track is positioned in the buffer groove block fixed on the pull rod; and one end of the making leaf spring is fixed on the fixing seat and the other end is in free state.

Description

technical field

[0001] The invention relates to an automatic thread locking machine, in particular to a buffer positioning mechanism therein. Background technique

[0002] Sewing machine is a book binding equipment that makes book blocks by sewing signatures. It is generally composed of systems such as page input, buffer positioning, transmission, thread locking, book counting and electrical control. The pager puts the signatures on the guide rail of the conveyor chain, pushes the book signatures to the book delivery wheel, and the high-speed rotating book delivery wheel sends the signatures to the stapler. The stapler swings to the locking position after receiving the signatures At the same time, the buffer and the pull gauge installed on the stapler buffer and position the signature. Then, the base installed under the stapler punches holes for the signature, and the threading needle moves downward to thread under the drive of the lifting frame. The hooking claw and the cr...
