[0012] The utility model has the following beneficial effects:

[0013] During the rotation of the roller, one of the roller shafts provides a power source to the air supply component. When the air supply component runs, the generated wind is transported to the air outlet component. The wind blows toward the outer wall of the roller through the air outlet component, and the dust adhered to the outer wall of the roller is blown off and cleaned. Therefore, during the use of the belt roller, it is easy to blow off and clean the dust adhered to the outer wall of the roller through its own operation, thereby reducing the degree of wear on the roller and the belt.
