Ceramic anilox roller used for optical thin film printing

Abstract

The invention discloses a ceramic anilox roller used for optical thin film printing. Through the heat treatment and hardening and tempering for the ceramic anilox roller, a base body is hardened, and surface hardness of the base body reaches HV 1200-1300. Compared with a chroming anilox roller, the ceramic anilox roller used for the optical thin film printing reaches HV 1200-1300 in hardness, the hardness is increased by 50%, mechanical concentricity deviation is smaller than or equal to 0.03 millimeter, mechanical run-out extent is reduced by 66%, layout smoothness reaches 0.1 and is increased by 66%, and evenness deviation of finished film materials is reduced to 2-4% and evenness performance is increased by 100%.

Description

technical field [0001] The invention relates to a printing plate roller, in particular to a ceramic anilox roller for optical film printing. Background technique [0002] Most of the optical film printing in the prior art adopts chrome-plated anilox rollers. The disadvantages are: the hardness of the chrome-plated anilox rollers is HV800-900, and the wear resistance is poor; mm, length 1700 mm), the mechanical beating range is large, and the ink throwing phenomenon is prone to occur during the printing process; the smoothness of the layout is poor, resulting in a large deviation in the uniformity of the finished film material layer, reaching 8-15%. In addition, chrome-plated rollers generally use extrusion to process dots. If the substrate is hardened, extrusion processing cannot be performed after treatment. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned problems in the prior art and provide a ceramic anilox roll...

[0002] Most of the optical film printing in the prior art adopts chrome-plated anilox rollers. The disadvantages are: the hardness of the chrome-plated anilox rollers is HV800-900, and the wear resistance is poor; mm, length 1700 mm), the mechanical beating range is large, and the printing process is prone to ink rejection; the layout is poor, resulting in a large deviation in the uniformity of the finished film layer, reaching 8-15%

In addition, chrome-plated rollers generally use extrusion methods to process dots. If the substrate is hardened, extrusion processing cannot be performed after treatment.
