The utility model provides an electroplated layer spraying device which is characterized in that in the working process of the electroplated layer spraying device, one end of a tubular workpiece to be sprayed is inserted into an annular receiving groove. The screw is driven to rotate through the driving head, the fixed extrusion pad is driven to extrude the outer wall of the tubular workpiece to be sprayed in the rotating process of the screw, and therefore the tubular workpiece to be sprayed is fixed to the annular bearing plate. The rotating motor drives the annular bearing plate through the rotating plate to drive the tubular workpiece to be sprayed to rotate. The driving air cylinder drives the two spraying heads to move inside and outside the tubular workpiece to be sprayed through the driving connecting plate and the two spraying pipes. In the process, the pumping pump supplies materials towards the two spraying heads through the pumping pipe, the pumping connector, the two conveying hoses and the two spraying pipes. And the two nozzles move up and down to spray the rotating tubular workpiece to be sprayed. The electroplated layer spraying device is low in spraying operation efficiency for tubular products, simple and exquisite in structure and low in cost.

Description

Technical Field

[0001] This utility model relates to the field of electroplating coating spraying, and in particular to an electroplating layer spraying device. Background Technology

[0002] Electroplating is the process of depositing a thin layer of another metal or alloy onto the surface of certain metals using the principle of electrolysis. It utilizes electrolysis to coat the surface of metal or other material parts with a metallic film, thereby preventing metal oxidation, improving wear resistance, conductivity, reflectivity, corrosion resistance (such as copper sulfate), and enhancing aesthetics. After electroplating, the coating needs further processing. Among these processes, painting is a crucial step in protecting the coating.
