This utility model relates to the field of coating machine technology and discloses a scraper structure for a wall panel cold glue coating machine. It includes a conveyor box, with supports fixedly connected to both sides of the conveyor box. A first lead screw is movably sleeved inside the supports, and a connecting plate is threaded onto the outside of the first lead screw. A horizontal plate is fixedly connected to the lower end of the connecting plate, and an inclined plate is hinged to one side of the horizontal plate. This scraper structure for the wall panel cold glue coating machine allows the scraper to be mounted at the front end of a scraper mounting base. A limiting sleeve restricts the position of the scraper, and a first spring pushes a buckle to engage inside the scraper. This improves the flexibility of the scraper when mounted at the front end of the scraper mounting base. Furthermore, an extension rod is activated to adjust the angle of the scraper and the position of the sliding plate inside the sliding sleeve, thus adjusting the distance between the scraper and the wall panel and improving the accuracy of the scraper in controlling the thickness of the glue scraped off.
