Durable intaglio printing rubber roller

Abstract

The invention provides a durable intaglio printing rubber roller which comprises a metal central spindle, a foaming layer, an inner-layer rubber layer, a middle-layer rubber layer and an outer-layer rubber layer which are sequentially packed outside the metal central spindle, and two end covers arranged at side faces of the metal central spindle, wherein the shore hardness of the inner-layer rubber layer is larger than that of the middle-layer rubber layer, and the shore hardness of the middle-layer rubber layer is larger than that of the outer-layer rubber layer; the middle-layer rubber layer is internally provided with hollow channels which are arranged with one another at intervals; and the two end covers arranged at the side faces of the metal central spindle are provided with holes which correspond to the positions of openings arranged at two ends of the hollow channels in the inner-layer rubber layer. The rubber roller provided by the invention is the ceramic tile intaglio printing rubber roller which is durable, can print on the concave-convex tile surface and the plane, is better in printing effect on the concave-convex tile surface, and is longer in service life.

Description

technical field [0001] The invention relates to a durable ceramic tile gravure printing rubber roller capable of printing on a concave-convex brick surface. Background technique [0002] Due to structural disadvantages, most of the rubber rollers for gravure printing of ceramic tiles in the prior art are only suitable for printing patterns on the surface of flat ceramic tiles. Print patterns on the surface, but its service life is short. Generally, it can only print about 30,000 square meters of products on the concave-convex brick surface continuously. There are pits and degumming and cannot continue to be used. When the unevenness of the tile surface is large, its service life is shorter, and the above-mentioned defects appear after only about 10,000 square meters of products can be printed continuously, resulting in high production costs. The frequency of workers replacing the rubber rollers is too high, the labor intensity is high, and the color of the product will be a...

[0002] Due to structural disadvantages, most of the rubber rollers for gravure printing of ceramic tiles in the prior art are only suitable for printing patterns on the surface of flat ceramic tiles. Print patterns on the surface, but its service life is short. Generally, it can only print about 30,000 square meters of products on the concave-convex brick surface continuously. There are pits and degumming and cannot continue to be used. When the unevenness of the tile surface is large, its service life is shorter, and the above-mentioned defects appear after only about 10,000 square meters of products can be printed continuously, resulting in high production costs. The frequency of workers replacing the rubber rollers is too high, the labor intensity is high, and the color of the product will be affected after each replacement of the rubber rollers, and the continuous use of these rubber rollers on the uneven brick surface will cause metal mandrels and end caps Deformation or cracking due to stress, so that it cannot be recycled and causes great waste
