Novel embossing roller manufacturing process

Abstract

The invention relates to a novel embossing roller manufacturing process. The manufacturing process comprises the following process operation steps: S1, sampling by laser scanning; S2, carrying out pattern processing on scanned patterns by a computer to generate a 3D seamless spliced file; S3, carrying out digital processing on the 3D file to enable the 3D file to be used for laser engraving; S4, selecting rubber capable of being engraved by laser, and engraving and reducing the patterns to the surface of the rubber; S5, casting liquid silica gel on the surface of an engraved rubber mold, drying and curing, and reducing the rubber surface patterns to the surface of the silica gel; and S6, removing a silicon gel sleeve, and sleeving the surface of a steel roller with the silicon gel sleeve for embossing operation. According to the novel embossing roller manufacturing process, the silicon gel sleeve is arranged on the surface of the steel roller in a sleeving mode to be used for carryingout embossing process treatment, so that the grains on the surface of a pressed object achieve a series of effects of matting, clear pattern layer, no seam, soft pattern edge transition and the like.An embossing roller manufactured by the process is lower than a prior embossing roller in manufacturing cost, and the grains are adjusted conveniently.

Description

technical field [0001] The invention relates to the technical field of embossing roller manufacturing, in particular to a novel embossing roller manufacturing process. Background technique [0002] With the advancement and development of modern science and technology, silica gel is widely used in various fields such as aviation, navigation, spacecraft, rocket missiles, atomic energy, and electronic and electrical industries because of its high temperature resistance, stable adhesion, and good durability. With the gradual expansion of the application range of silica gel, all walks of life have put forward higher requirements for the quality and performance of silica gel coils. [0003] Existing embossing rollers usually use computer laser engraving, chemical etching, manual chiseling, etc. to directly engrave patterns on the surface of the roller body. The disadvantages of the above methods are that the three-dimensional effect of the pattern is not strong, the 3D effect and ...

Problems solved by technology

[0003] Existing embossing rollers usually use computer laser engraving, chemical etching, manual chiseling, etc. to directly engrave patterns on the surface of the roller body. The disadvantages of the above methods are that the three-dimensional effect of the pattern is not strong, the 3D effect and simulation effect are poor, and The continuity of the pattern is not good, the transition is not soft, and the processing on the surface of the steel roll will increase the production cost. At the same time, the waste cost is high and the enterprise expenditure will be increased. A new embossing roll production process is urgently needed to solve the existing technical problems.
