The application discloses a multistage
temperature control sanding device for
asphalt waterproof coiled material production, which comprises a rack, a preheating cover, a high-temperature cover, a medium-temperature cover and a low-temperature cover are bolted to the upper portion of the rack, and electric heaters are penetrated through the two sides of the preheating cover, the high-temperature cover, the medium-temperature cover and the low-temperature cover, the application is characterized in that a rotatable feeding
pipe screening structure is integrated in the
bunker, a main gear is driven by a
servo motor to mesh with an external tooth ring to drive the feeding
pipe to rotate, the screen holes uniformly distributed on the surface of the feeding
pipe are used for dynamically screening the input sand materials, and the mixed large-
diameter impurity particles in the sand materials can be effectively removed; meanwhile, a self-locking motor-driven discharging roller and a quantitative discharging structure with a through groove are matched, the sand materials can be controllably and uniformly discharged, the problems of the
bunker and the discharging channel blockage caused by the absence of a screening mechanism in the traditional sanding device are solved, the equipment operation stability is improved, the continuous and efficient development of the sanding process of the
asphalt waterproof coiled material is ensured, and the equipment
downtime and maintenance frequency are reduced.
