Paint spraying device for automobile processing

The invention discloses a paint spraying device for automobile processing, and relates to the field of paint spraying equipment. Through the arrangement of the lifting assembly, the transmission seat, the sliding sleeve and the convex plate, under the action of the lifting assembly and the transmission seat, due to the fact that the transmission seat and the sliding sleeve are rotationally connected, the sliding sleeve can move downwards when the lifting assembly operates, so that the scraping plate can evenly scrape the inner wall of the lower tank body, and meanwhile due to the fact that the scraping plate is located in the upper tank body when not in use, the scraping plate is not prone to falling off. The inner diameter of the upper tank body is larger than that of the lower tank body, so that the scraping plate is not in contact with the inner wall of the upper tank body, the abrasion of the scraping plate is reduced, the scraping plate can synchronously rotate along with the stirring rod under the actio
