The utility model relates to the technical field of mesh belt processing equipment, specifically a polishing device for mesh belt processing, including a base, a support column vertically arranged on the surface of the base, cooling and dust removal mechanisms respectively arranged on both sides of the support column, the cooling and dust removal mechanism comprising an exhaust fan, the bottom of the exhaust fan is fixed on an inclined plate, one side of the inclined plate is fixedly connected to a connecting protrusion on the base by bolts, and the bottom of the inclined plate away from the bolt is connected to the base by a telescopic spring.
The utility model arranges cooling and dust removal mechanisms on both sides of the support column of the base, and fixes the inclined plate and the connecting protrusion by bolts in conjunction with the angle change of the inclined plate and the connecting protrusion, thereby adjusting the angle of the exhaust fan. The exhaust fan extracts metal dust generated during the polishing process from time to time, and takes away the heat generated by the polishing roller at the same time, thereby achieving a cooling effect, which effectively protects the respiratory health of the operator and improves the polishing quality.
