Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic spraying, in particular to an electrostatic spraying device for the surface of an aluminum profile. Background Art

[0002] Electrostatic spraying is a coating method that uses the principle of corona discharge to charge atomized paint negatively under the action of a high-voltage DC electric field, and then adsorbs and discharges on the surface of a positively charged substrate. Electrostatic spraying equipment consists of a spray gun, a spray cup, and an electrostatic spray high-voltage power supply. During the processing of aluminum profiles, in order to reduce the erosion intensity of the external environment and extend its service life, it is often necessary to spray a layer of protective paint on its outer surface to block the erosion of the external environment and increase its service life.

[0003] Existing electrostatic spraying is mostly carried out in a closed spray room to avoid pollution and waste caused by exposed paint. The spray gun uses a diffusion nozzle and has manual or robotic arm assisted displacement spraying. It can only spray the outer surface of the aluminum profile on one side or both sides, which is not comprehensive enough and the spraying quality is not high. It needs to change the angle for multiple reciprocating spraying, which will reduce the overall electrostatic spraying efficiency. Utility Model Content
