A punching device for thread-bound books

Abstract

The invention discloses perforating equipment for a thread-bound book. The perforating equipment comprises a first working bottom plate; a second working bottom plate is fixedly installed at one end of the first working bottom plate; the four corners of the bottom end of the first working bottom plate and the four corners of the bottom end of the second working bottom plate are all provided with anti-slide bases; the two sides of the first working bottom plate and the two sides of the second working bottom plate are symmetrically provided with adjusting slide grooves; aligning mechanisms are slidably installed in the positions closing to the interiors of the connected ends of the first working bottom plate and the second working bottom plate; supporting columns are symmetrically and fixedly installed at the tops of the connected ends of the first working bottom plate and the second working bottom plate; and fixing pins are symmetrically installed on the supporting columns located on the first working bottom plate. The perforating equipment can quickly and accurately adjust and regulate the distance between perforated holes of the book and rapidly flat the book, the effect that theperforated holes are located on the same straight line in the transversal, longitudinal, horizontal and vertical directions, in addition, the perforating efficiency is high, and holes different in distance can be perforated at the same time.

Description

technical field [0001] The invention relates to the technical field of punching equipment for thread-bound books, in particular to a punching device for thread-bound books. Background technique [0002] Thread-bound books need to be punched through holes in the process of bookbinding, and then threaded. The existing punching equipment can only punch holes in thinner books, and the book cannot be well-punched during the punching process. Fixing makes it easy to cause damage to the books around the punching process during the punching process, and the existing punching equipment is inconvenient to adjust the spacing between the punching needles, and the spacing adjustment is not uniform, so that the punched hole spacing is not equal , affect the threading and aesthetics, and the existing punching equipment has low punching efficiency, which affects the punching efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a punching devic...
