Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, and particularly relates to a workpiece transfer device for an electroplating line. Background Technique

[0002] A plate cylinder, also called a steel roller, is generally used for plate making. Its roller surface is plated with copper, and after being engraved with patterns by an intaglio electronic engraving machine, a layer of chromium is plated, and it is commonly used for the printing of plastic packaging. In the production and manufacturing process of the plate cylinder, it is usually necessary to electroplate the plate cylinder. Electroplating is a process of plating a thin layer of other metals or alloys on the surface of certain metals by using the electrolysis principle. It is a process of making the surface of metal or other material parts adhere to a layer of metal film by using electrolysis, so as to prevent metal oxidation, improve wear resistance, electrical conductivity, reflectivity, corrosion resistance and enhance beauty, etc.

[0003] In the patent with the patent number CN202320421020.0, a plate cylinder electroplating transfer mechanism is disclosed, including a connecting frame. The connecting frame is a rectangular frame structure, and support legs are correspondingly arranged around its bottom. Casters are correspondingly installed at the bottom of the support legs; Lift frames that can be lifted are correspondingly arranged on both sides of the top of the connecting frame. A plurality of sliding rods longitudinally spaced are correspondingly arranged between the two lift frames on both sides. A plurality of telescopic hanging frames are correspondingly installed below the sliding rods. The hanging frames can slide horizontally and be limited along the sliding rods so as to hook the plate cylinders; A liquid collecting tray is detachably installed at the bottom of the connecting frame.

[0004] The above patent has the following problems:

[0005] It cannot be finely adjusted according to the length of the plate cylinder, and it is necessary for workers to manually adjust a plurality of hanging frames, with a low degree of automation, increasing the labor intensity of workers. Therefore, we have developed a workpiece transfer device for an electroplating line. Content of the Utility Model
