FORWARD AND REVERSE ROTATION POLISHER

摘要

A forward and reverse rotation polisher includes a housing (10), a motor (20), a polishing device (30) and a forward and reverse rotation device (40). The motor (20) is fixed on the housing (10) and is provided with a driving shaft (21). The polishing device (30) includes a first polishing unit (31) and a second polishing unit (32). The two polishing units each include a fixed disc and polishing material which is fixedly connected with the outside of the fixed disc. The fixed discs are perpendicular to the driving shaft. The polishing surfaces of the first polishing material (312) and the second polishing material (322) are in the same plane, and make concentric and reverse rotation. The forward and reverse rotation device (40) includes a first driving wheel (41), a second driving wheel (42) and a steering wheel (43). The first driving wheel (41) is connected with and is driven by the driving shaft (21), and the second driving wheel (42) is fixedly connected with the second fixed disc (321). The steering wheel (43) is connected with the first driving wheel (41) and the second driving wheel (42). The first fixed disc (311) is connected with and is driven by the driving shaft (21), so as to realize the forward rotation of the first polishing material (312). The rotation of the first driving wheel (41) is transmitted reversely to the second driving wheel (42) by the steering wheel (43), so as to realize the reverse rotation of the second polishing material (322). The polisher can improve polishing effect.
