Title: Polishing equipment for fixing belt
Inventor: CHOI CHANG HO
IPC: B24B9/02
Filed: 2020-02-12
Abstract: The present invention relates to a polishing device for a fixing belt. The present invention comprises: a support part formed on an upper surface of a worktable; a rotating roller with both outer ends on which a support of the support part is supported; a rotating clamp installed on the upper surface of the worktable and coming into contact with a distal end of a support rod of the rotating roller; a moving clamp formed on the upper surface of the worktable opposite to the rotating clamp and coming into contact with the distal end of the support rod; and a polishing device provided on the upper surface of the worktable and configured to polishing both ends of a fixing belt. A polishing member of the polishing device moves from the inside to the outside at both ends of the fixing belt to enable the polishing member to perform polishing, such that burrs formed on edges of both ends of the fixing belt are swept outward by the polishing member. Accordingly, the polishing member polishes inner edges of the fixing belt while removing the burrs on the inner edges of the fixing belt. In accordance with the present invention, the polishing member removes burrs formed on the inner edge of the fixing belt while moving from the inside to the outside at both ends of the fixing belt, such that the burrs are removed. At the same time, the inner edges at both ends of the fixing belt are polished by friction force between the inner edges of the fixing belt and the polishing member. Because the burrs are removed, there is no risk of scratches on the outer surface of the fixing belt and a surface of paper guided and moved by the fixing roller when the fixing belt is coupled to the fixing roller. In addition, by a simple process of attaching the polishing member automatically moved by the polishing device to both ends of the fixing belt, both ends of the fixing belt can be easily polished.
