Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic coating equipment, in particular to a profile coating electrolytic processing equipment based on membrane exchange. Background Art

[0002] Profiles are materials with different cross-sectional shapes obtained by hot melting and extrusion of rods. The production process of profiles mainly includes three processes: melting, extrusion and coating. The coating methods include oxidation, electrophoresis and electrostatic powder spraying. Oxide coating is a process that uses the principle of electrolysis to coat a thin layer of other metals or alloys on the surface of the profile, thereby playing a role in anti-oxidation of the profile surface, improving wear resistance, conductivity, reflectivity, corrosion resistance and enhancing aesthetics.

[0003] The existing profile surface coating device suspends the profile inside the electrolytic cell through a lifting device, which is not convenient to use and has the risk of the profile falling off during the coating process, posing certain safety hazards. At the same time, during use, the existing profile surface coating device keeps the profile stationary in the coating liquid, resulting in low coating efficiency and poor consistency in coating thickness, which affects the later use effect of the profile.

[0015] Furthermore, sliding guide rails are provided on both sides of the workpiece carrier, and the lifting beam is slidably engaged with the two sliding guide rails respectively;

[0016] Note: The provision of sliding guide rails can help improve the stability of the lifting beam when it moves on the workpiece carrier, thereby improving the safety of the equipment during use.

[0021] Secondly, the utility model utilizes a rotary motor to drive the clamping chuck to rotate, so that the profile can rotate in the coating liquid during the coating process, which can improve the uniformity of the coating thickness on the profile surface; the coating surface of the profile can be dried by a dryer, shortening the coating processing cycle of the profile;

[0022] Third, the present invention can reduce the concentration of impurity gases generated during the oxidation reaction of the anode electrode by arranging an ion exchange membrane inside the electrolytic cell; at the same time, it can reduce the electrolysis power supply, thereby reducing the energy consumption of the equipment.
