ROLLER FOR BELT CONVEYOR WITH ROTATING FAN FOR PREVENTING FIXING OF THE ROLLER

摘要

PURPOSE: A fan is formed in both ends of a roller body to prevent dust to a bearing portion of a roller, thereby preventing fixing of the roller. CONSTITUTION: A roller body(21) rotates by contacting with lower surface of a belt to prevent slacking of the belt. A roller shaft(22) is fixed to be a rotating center of the roller body. A bearing portion(23) is formed in both ends of the roller body to reduce friction resistance between the roller body and the roller shaft. A fan(25) rotates with the roller body, and is fixed in both ends of the roller body covering the bearing portion.
