Engineering wall cloth reverse coating machine

The utility model provides an engineering wall cloth reverse coating machine which is used for solving the problems that the surface of a thin film is uneven and time consumed for cleaning a net is long when the thickness of the thin film is increased. The reverse coating machine comprises an unwinding device, a drying oven fixedly arranged on the right side of the unwinding device, a reverse coating mechanism fixedly arranged below the drying oven and a winding device fixedly arranged on the right side of the reverse coating mechanism, a cooling roller is rotatably arranged between the reverse coating mechanism and the winding device, and a winding roller is rotatably arranged on the winding device. Through mutual cooperation of the scraper and the scraping roller, part of slurry on the material rotating roller can be scraped, and the thickness of the slurry on the material roller is adjusted, so that the slurry is uniformly smeared on the surface of a base material. 本实用新型提出了一种工程墙布逆涂机，用以解决增加薄膜厚度会存在薄膜表面不平整、清网
