Scraping roller

The invention belongs to the technical field of building board manufacturing, and particularly provides a scraping roller. The scraping roller comprises a cylindrical base body and shaft heads connected to the two ends of the cylindrical base body correspondingly. A plurality of rows of rubber are distributed on the side wall of the cylindrical base body in the radial direction of the cylindrical base body. A plurality of pieces of rubber are distributed in each row along the axis of the cylindrical base body. The positions of the rubber in every two adjacent rows are staggered in the axis direction of the cylindrical base body. The rubber is in a board shape and is arranged in the radial direction of the cylindrical base body. By means of the cylindrical base body and the rubber arranged in the radial direction and the axial direction, in the form board cleaning process, all the rubber is sequentially in contact with form boards, and therefore the situation that parts of the form boards cannot be cleaned is
