Laser roller film engraving machine

Abstract

The invention relates to the field of roller laser processing system, more particularly to a laser roller film engraving machine. Being a relatively advanced plate making way at present, roller film engraving technology is mainly characterized in processing in that: according to the trace of plate pattern, laser is applied to a protective layer which is pre-coated over the surface of a roller, the part of the surface of the roller, which is exposed due to the falloff of the protective layer, is the plate pattern to be processed, and the roller is then subject to corrosion treatment to finally form the plate pattern. As a special machine aiming at the above processing way, the laser roller film engraving machine comprises: a graphic and image processing system, a control system, a mechanical system, a laser and an optical system, wherein the optical system comprises an acoustic optic deflector to achieve the light-splitting and time-sharing control for laser, so that the processed plate pattern is more exquisite, and a double-layer optical fiber laser generator is adopted to realize high stability of laser power and excellent quality of light beam.

Description

technical field [0001] The utility model relates to the field of laser processing systems for plate rollers, in particular to a laser engraving and engraving machine for plate rollers. Background technique [0002] In recent years, the plate engraving technology has become a relatively advanced plate-making method. The main processing features are: the laser is used to act on the pre-coated protective layer on the surface of the plate according to the track of the plate pattern, and the protective layer falls off to expose the surface of the plate. The printing plate pattern, and then the plate roller is corroded and cleaned to finally form the printing plate pattern. However, most of the current laser engraving machines directly process the printing plate pattern on the cylindrical surface of the plate roller through the laser beam, and there is no special laser engraving equipment for the above-mentioned processing method. [0003] Chinese patent CN1299723 discloses a sys...

AI Technical Summary

Problems solved by technology

The device uses multiple laser beams to focus and combine beams, which improves the processing efficiency, but there are still defects: the device uses more than two YAG lasers, but the beam quality of the YAG laser itself is not high, and more than two YAG lasers require two sets of optical paths system, which increases the cost
