[0006] By adopting the above technical solutions, the staff fixes the plastic parts to be painted on the fixing hook, starts the first lifting member and the first rotating member, drives the plastic parts to lift and rotate. Thus, the horizontal paint nozzles on the inner wall of the annular painting pipe can evenly paint the surface of the plastic parts. Compared with the manual painting method, the device of this application sprays paint more evenly and has higher efficiency, improving the production quality and production efficiency of plastic parts. This application does not require manual direct painting, which can reduce the harm caused by painting to the human body.

[0048] The implementation principle of a paint spraying device for producing interior plastic parts of new energy vehicles in an embodiment of the present application is as follows: The staff fixes the plastic parts to be painted on the fixed hook 303, starts the rotating mechanism, rotates the sealing cover 5, and aligns the notch 501 with the exhaust hood 4; starts the first lifting member 3 and the first rotating member 302 to drive the plastic parts to lift and rotate. Thus, the horizontal paint spraying nozzles 202 on the inner wall of the annular paint spraying pipe 2 can evenly spray the surface of the plastic parts; when it is necessary to spray the top or bottom of the plastic parts, start the adjusting cylinder 203. One of the two adjusting cylinders 203 on both sides extends, and the other shortens, so that the annular paint spraying pipe 2 can change its angle, and then adjust the angle of the inclined paint spraying nozzle 204, cooperate with the first lifting member 3 and the first rotating member 302 to achieve spraying on the top and bottom of the plastic parts. The device of the present application sprays paint more evenly and has higher efficiency, improving the production quality and production efficiency of plastic parts; during the paint spraying process, the sealing cover 5 and the exhaust hood 4 cooperate with each other to discharge the gas carried by the paint, saving the time for waiting for the gas carried by the paint to volatilize. At the same time, a cleaner is sprayed by the atomizing nozzle 503 to prevent the paint from solidifying on the inner wall of the sealing cover 5. The present application does not require manual direct paint spraying, which can reduce the harm caused by paint spraying to the human body. After the paint spraying is completed, the drying port 509 is opened, hot air enters the sealing cover 5, and the hot air convection cover 8 can also improve the curing speed of the paint, further improving the production efficiency. After drying is completed, the sealing cover 5 rotates further to facilitate the staff to unload the plastic parts from the notch 501.
