Abstract

The invention discloses a rotation abutting conveying paper cutting device of a printing machine. The rotation abutting conveying paper cutting device comprises a bracket and a paper cutting device; the left portion of the upper end surface of a lower supporting plate is provided with a left supporting plate; the paper cutting device comprises a lifting supporting plate, a pair of cylindrical rotation center columns which are synchronously and rotationally arranged, and a pair of length supporting blocks which are symmetrically arranged in the front-back direction and can move leftwards and rightwards; an upper avoiding groove is formed in the center of the right end of the upper supporting plate, and a lower avoiding grove is formed in the center of the right end of the lower supporting plate; the pair of rotation center columns are rotationally arranged between a pair of upper front and back supporting plates and a pair of lower front and back supporting plates; the rotation center columns are elastically and movably provided with first pressing blocks and second pressing blocks in the radial direction; the lifting supporting plate is arranged in the middle f the lower end surface of the upper supporting plate in a lifting mode; a cutter is detachably installed on the lower end surface of the lifting supporting plate; and the left portion of the lower end surface of the uppersupporting plate is rotationally provided with a left driving roller. The rotation abutting conveying paper cutting device is simple in structure, the paper cutting length is controllable, and the precision is high.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a paper-cutting device that rotates against and conveys a printing machine. Background technique [0002] With the progress of society, all walks of life are developing, and the printing industry is also one of the rapidly developing industries. When carrying out large-scale printing work, the content to be printed is usually printed on a long roll of paper multiple times, and then the paper roll is cut and torn after printing, and then the different pages are separated. The current printing mechanical tearing device has low adjustment ability for cutting paper rolls into different lengths, and the accuracy of cutting paper is also low. It will be troublesome for printing workers to use, work efficiency is low, and the quality of the produced products is poor. . Contents of the invention [0003] The object of the present invention is to address the deficiencies of...
