Description

Technical Field

[0001] The utility model belongs to the technical field of spraying of automobile plastic parts, and particularly relates to a spraying device for automobile plastic parts. Background Art

[0002] The technical background of the spraying device for automobile plastic parts involves the painting process in automobile manufacturing. In the automobile industry, painting is an important step to improve the aesthetics, corrosion resistance and protection performance of automobile parts. During the spraying process, paint is sprayed into fine particles, which form an aerosol in the air and then are atomized and evenly covered on the surface of plastic parts. In order to capture these paint particles and prevent environmental pollution, a water curtain or an activated carbon filter is usually set in the spraying chamber. However, a major problem faced by traditional spraying devices is that the water curtain can only adsorb larger paint particles, and the adsorption effect of the water curtain on fine particles in the paint particle mixture in the form of aerosol is poor. This means that tiny paint particles in the air can float freely, resulting in air pollution in the spraying chamber and affecting the health of workers and the environmental quality. Summary of the Utility Model

[0003] In order to overcome the problem of the existing spraying device for automobile plastic parts, in which the paint particle mixture in the form of aerosol cannot be adsorbed after the water curtain adsorbs the sprayed paint, resulting in air pollution filled with air.
