Description

Flexographic printing machine Technical Field The utility model relates to the technical field of printing machines, in particular to a flexographic printing machine. Background Flexography is a printing process commonly employed in packaging printing equipment. The flexography has the advantages of 1 good printing applicability, capability of printing various types of materials such as paper, plastic, aluminum foil and the like, 2 relatively simple printing process of a flexography machine, convenient operation, easy realization of automatic production, and 3 rich color expression of printed matters and clear images. The main mechanism of flexography consists of a plate roller, a screen roller, a driven roller and a scraper, and the plate roller and the screen roller are mostly in sleeve type structures at present, and the plate roller and the screen roller are replaced every time when a printing product is replaced. The printing process comprises the steps of returning the plate roller and the net wire roller to initial positions after printing work is completed, fixing shaft heads of the plate roller and the net wire roller at the transmission side, manually pulling out an operation side supporting seat axially, separating from the supporting position, turning the supporting seat to the side, leaving a space position where the sleeve is withdrawn, and then withdrawing the plate roller sleeve and the net wire roller sleeve respectively for sleeve replacement.
