Description

Technical Field

[0001] The utility model relates to a surface plastic spraying device for a display bracket. Background Art

[0002] Plastic spraying is a surface treatment technology. It uses plastic powder, which is charged by a high-voltage electrostatic device and then sprayed onto the surface of a workpiece. After that, it is cured by high-temperature baking to form a coating. As shown in Figures 7-8 the display bracket, which is one of the components of a wall-mounted display bracket. The bracket is formed by stamping. After forming, it still needs to be plastic sprayed on the surface. In the existing plastic spraying process, generally, a single plastic spraying method is adopted. The bracket is placed in a plastic spraying box manually or by a manipulator and taken out after plastic spraying is completed. This not only has low efficiency, but also the placement position is prone to deviation each time, affecting the overall plastic spraying uniformity. Content of the Utility Model
