Problems solved by technology

[0002] At present, silk screen printing is the main method of producing matte cigarette packs, but the screen printing format is too narrow, the speed is slow, and the efficiency is low. In addition, during the silk screen printing process, the thickness of the ink transferred to the paper is too thick, which causes waste and is not environmentally friendly. The drying is not easy to control, and sometimes the drying temperature is too high and even the paper will burn, resulting in fire, resulting in personal property loss; the above shortcomings can be overcome by gravure matte printing, gravure printing has a large format, fast speed, high efficiency, and gravure Matte printing instead of screen can precisely control ink thickness, reduce waste and be environmentally friendly

Embodiment 1

[0017] A method of engraving a gravure matte plate roller by laser, the specific production steps are as follows:

[0018] ① Glue wrapping: Stand the roller upright, put a circular film on the outer circle of the roller according to the thickness of the glue layer required by the production, the outer circle of the film is connected with the circle to form a box, and the box is filled with glue. Driven by the 20Hz power of the motor, the film moves vertically and downward along the roller at a constant speed. The outer diameter of the roller is evenly coated with a layer of glue with a thickness of 0.01mm. After the application is completed, let the glue layer dry naturally. The drying process It usually takes 30 minutes, so that the rubber covering of the roller is completed;

[0019] ② Burning glue: put the glued and dried roller into the laser engraving machine, send the pattern designed in the computer to the engraving machine through the circuit connection, and completely...

Embodiment 2

[0030] A method of engraving a gravure matte plate roller by laser, the specific production steps are as follows:

[0031] ① Glue wrapping: Stand the roller upright, put a circular film on the outer circle of the roller according to the thickness of the glue layer required by the production, the outer circle of the film is connected with the circle to form a box, and the box is filled with glue. Driven by the 20Hz power of the motor, the film moves vertically downward along the roller at a constant speed. The outer diameter of the roller is evenly coated with a layer of glue with a thickness of 0.15mm. After the application is completed, let the glue layer dry naturally. The drying process It usually takes 40 minutes, so that the rubber covering of the roller is completed;

[0032] ② Burning glue: put the glued and dried roller into the laser engraving machine, send the pattern designed in the computer to the engraving machine through the circuit connection, and completely bur...

Embodiment 3

[0043] A method of engraving a gravure matte plate roller by laser, the specific production steps are as follows:

[0044] ① Glue wrapping: Stand the roller upright, put a circular film on the outer circle of the roller according to the thickness of the glue layer required by the production, the outer circle of the film is connected with the circle to form a box, and the box is filled with glue. Driven by the 20Hz power of the motor, the film moves vertically and downward along the roller at a constant speed. The outer diameter of the roller is evenly coated with a layer of glue with a thickness of 0.3mm. After the application is completed, let the glue layer dry naturally. The drying process It usually takes 45 minutes, so that the rubber covering of the roller is completed;

[0045] ② Burning glue: put the glued and dried roller into the laser engraving machine, send the pattern designed in the computer to the engraving machine through the circuit connection, and completely ...

Abstract

The invention relates to a method for engraving a gravure grinding roller by laser, which is applied to realizing gravure grinding printing. The method comprises the following specific manufacturing steps of (1) rubber coating, (2) rubber sintering, (3) corroding, (4) rubber removing, (5) chromium plating, and (6) checking. The method for engraving a gravure grinding roller by laser, disclosed by the invention, has the advantages that the depth requirement is strict, and 0.05mesh of net points can be controlled so that the printing ink content of each net point is uniform in a printing process; after the printing ink is subjected to gravure transfer printing, the thickness of a whole layout can be uniform, the leveling is good, the concave-convex feeling can be generated; compared with a silk screen manner, the gravure printing manner has the advantages of good third dimension, large printing format, high speed and high efficiency; and the thickness of the printing oil can be precisely controlled, the waste is reduced and the environment protection is realized.

Description

Technical field [0001] The present invention involves the field of production technology in the production of concave rollers. Specifically, it is a method of causing and matte roller roller that is carved by laser carving. Background technique [0002] At present, the production of cigarette bag matte is mainly silk printing, but the surface of the screen printing printing is too narrow, the speed is slow, and the efficiency is low. In the process of silk printing, the thickness of the ink to the paper is too thick, which produces waste and is not environmentally friendly.Drying is not easy to control. Sometimes the drying temperature is too high or even burn paper, causing fires, causing personal property losses; the above disadvantages can be overcome by concave printing and frosted.Printing and printing replace the silk net to accurately control the thickness of the ink, reduce waste and environmental protection. Invention content [0003] The purpose of the present inventio...
