Spiral shoveling plate structure for thermosetting polyurethane film coating roller

The utility model belongs to the technical field of shoveling plate structures, and particularly relates to a spiral shoveling plate structure for a thermosetting polyurethane film-coated roller, which comprises a film-coated roller, the installation inclination angle alpha between the film-coated roller and the ground is 0.5-4.5 degrees, a spiral straight-edge shoveling plate is arranged on the film-coated roller, and the spiral straight-edge shoveling plate is connected with the spiral straight-edge shoveling plate. A rectangular edge folding shoveling plate, a discharging shoveling plate, a feeding and discharging end and an overhauling end are arranged on the film coating roller, and the end face of the film coating roller is in a cone shape. Due to the adoption of the design of the spiral straight-edge shoveling plates, the shoveling plates penetrate through the head and the tail of the roller and have a guiding effect on the motion trail of particles, and the particles can rapidly roll in the spiral dir
