Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of workpiece flushing, and particularly relates to a pretreatment spray flushing equipment for a plastic spraying assembly line. BACKGROUND

[0002] A plastic spraying assembly line is a mechanized coating production line that uses electrostatic spraying technology to apply powder coating to the surface of a workpiece using a high-pressure airless sprayer. It is mainly used for protecting and beautifying the surface of objects. Its working principle is to spray the coating material through the nozzle onto the surface of the object to form a uniform protective film. This process usually requires an automated assembly line production system that can automatically transport objects from one workstation to another for processing.

[0003] Among them, the surface of the workpiece treated by plastic spraying will form a layer of thick or thin oil stains due to stamping, handling and other processes. The oil stains will isolate the workpiece and the coating, affecting the adhesion of the coating, and even causing problems such as blistering and cracking. Therefore, before electrostatic plastic spraying, a spray flushing equipment can be used to remove oil stains, oil stains and impurities on the surface of the workpiece to increase the adhesion of the coating.

[0004] Traditional spray flushing equipment generally uses a high-pressure water gun to flush the surface of the workpiece. However, it is difficult to flush the oil in the concave and convex grooves of the workpiece with a fixed water gun. Therefore, the existing spray flushing equipment selects a flushing method in which the flushing angle of the water gun can be changed. However, during the process of changing the flushing angle of the water gun, it is difficult to control the water pressure of the water gun on the surface of the workpiece, resulting in different water pressures in different areas and the possibility of incomplete flushing due to reduced local water pressure.
