NOVELTY - The utility model claims a graphene crystal polishing device, relating to graphene field. The graphene crystal polishing device comprises a fixing cavity, the outer surface of the fixing screw thread is connected with an upper sealing cover, the inner top wall of the upper sealing cover is fixedly installed with a polishing mechanism, the polishing mechanism comprises a supporting frame, the supporting frame is fixedly installed on the inner top wall of the upper sealing cover, the middle part of the supporting frame is fixedly installed with a motor. The graphene crystal polishing device can drive the driving gear to rotate through the motor work, the driving gear drives the limiting frame to rotate through the inner gear ring, so as to grind the graphene crystal by rotating the polishing sheet, at the same time, it can rotate to drive different extruding blocks and the touch head contact the driving fluted disc, so as to drive the grinding sheet to move through the supporting frame, so as to reach the grinding sheet to move while rotating, it solves the problem that the grinding sheet in the same position is easy to appear groove in the prior art.
