Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of gravure electroplating tank, especially to the cross type anode moving mechanism of gravure electroplating tank. BACKGROUND

[0002] Electroplating is a process of plating a thin layer of other metal or alloy on the surface of certain metal by electrolysis, which is a technology of attaching a metal film to the surface of metal or other material parts by electrolysis to prevent metal oxidation (such as rust), improve wear resistance, electrical conductivity, light reflectivity, corrosion resistance (copper sulfate, etc.), and enhance aesthetics.

[0003] Among them, the surface of the gravure roller in gravure printing needs to be plated with chromium by a chromium plating device. The chromium plating of the surface of the gravure roller can improve the surface hardness, protect the gravure roller, and improve the printing resistance of the gravure roller. At the same time, the chromium plating layer has strong hardness, wear resistance and chemical stability, so that the surface of the gravure roller after chromium plating can maintain gloss for a long time.

[0033] The anode plate 3 is arranged between the two shielding plates 11, the anode plate 3 is arranged perpendicularly to the shielding plates 11, the shielding plates 11 are formed with electroplating holes 17 for the gravure roller to enter; the anode plate 3 is symmetrically arranged on both sides of the electroplating hole 17 respectively, since the two anode plates 3 are arranged on both sides of the gravure roller, when the distance is adjusted, the two anode plates 3 will approach or move away from each other at the same time; the distance between the two anode plates 3 and the gravure roller is the same, which ensures that the paths of the free ions on both sides of the electroplating tank are basically the same, and the plated layer on the surface of the gravure roller after electroplating is more uniform and has better quality.

[0034] The sliding module 20 further comprises guide rails 24 obliquely arranged on the shielding plates 11, the two guide rails 24 are symmetrically arranged on the periphery of the electroplating hole 17 respectively, the guide rails 24 are slidingly installed with guide sliding seats 25, adjusting sliding seats 26 are installed on the top of the guide sliding seats 25, limit seats 27 are installed on the top and bottom of the guide rails 24 respectively.
