Abstract

The invention provides an intaglio press plate roller seal device, and relates to the technical field of printing. The technical problem that in the prior art, in the intaglio press usage process, thesealing performance between a tip cone and a plate roller is poor is solved. The intaglio press plate roller seal device comprises a center shaft and an elastic piece, one end of the center shaft isin sealed connection with a plate roller in an intaglio press shell through a tip cone; the other end of the center shaft is connected with a drive device after penetrating out of the intaglio press shell; the length of the center shaft can be adjusted, and the center shaft can relatively get close to or get away from the plate roller; and the elastic piece is arranged between the intaglio press shell and the tip cone, at least one end of the elastic piece is rotationally connected, and the elastic piece is constantly in a compressed state. The intaglio press plate roller seal device is used for improving the sealing performance between the tip cone and the plate roller in the intaglio press.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a sealing device for a plate roll of a gravure printing machine. Background technique [0002] Gravure printing is a direct printing method. It is widely used in the fields of printing, packaging and graphic publishing due to its advantages such as thick ink layer, bright color, high saturation, high printing durability, stable printing quality and fast printing speed. occupies an extremely important position. It directly embosses the ink contained in the pits of the plate roller onto the substrate. The shade of the printed picture is determined by the size and depth of the pits. The ink layer left on the substrate after printing is thicker; on the contrary, if the pit is shallower, the amount of ink contained is less, and the ink layer left on the substrate after embossing is thinner. [0003] The printing plate used in the gravure printing industry is fixed by means of pneum...
