High-speed curved printer capable of checking edition automatically

Abstract

The invention relates to a cambering printing machine, in particular to a high-speed cambering printing machine which can automatically proof the version. The invention solves the problem that the existing cambering printing machine, more particularly, the high-speed cambering printing machine can not implement the automatic match of color and proofreading of the version. The high-speed cambering printing machine which can carry out the automatic proofreading of the version additionally adds a longitudinal and transverse alignment driving device and a control device for the alignment driving device in a printing roller assembly on the base of the existing cambering printing machine. The longitudinal and transverse alignment drive device comprises a core shaft pin or an internal shaft pin, a thread adjusting package, a worm wheel, a worm, and a stepping motor; the control device for the alignment driving device comprises a rotary photoelectric encoder, a CCD camera, a PC and a PLC controller. The high-speed cambering printing machine which can implement the automatic proofreading of the version has the function of automatic match of color and proofreading of the version with scientific and reasonable structural design, filling up the vacancy of the non-automatic cambering printing machine.

Description

technical field [0001] The invention relates to a curved surface printing machine, in particular to a high-speed curved surface printing machine capable of automatic plate alignment. Background technique [0002] The curved surface printing machine includes a large rubber roller with a transfer blanket fixed on it, various color plate roller assemblies matched with the large rubber roller, a material tray matched with the large rubber roller, and a mold handle installed on it, driving the large rubber roller 1. The main transmission shaft system for the rotation of the material tray; the version roller assembly includes a mandrel on which an inner shaft sleeve and an outer shaft sleeve are sequentially sleeved, and a version roller and a circumferential adjustment helical gear device are sleeved on the outer sleeve of the mandrel. There is a guide rod connected between the circumferential adjustment helical gear device and the version roller. The version roller assembly also...
