NOVELTY - The utility model claims a graphene grinding and collecting device, relating to graphene field. The graphene grinding and collecting device comprises a grinding sleeve, the centre of the inner bottom wall of the grinding sleeve is provided with a groove, the inner part of the groove is slidingly connected with an exhaust sleeve, the bottom end of the exhaust sleeve is fixedly connected with the inner bottom wall of the groove through the reset spring; the inner bottom wall of the polishing sleeve is fixedly installed with a spacer, the edge of the polishing sleeve is provided with a discharge hole. The graphene grinding and collecting device, the graphene is placed between the spacer, and the end cover screw thread connected on the outer surface of the polishing sleeve, through the motor work can drive the grinding sheet and the graphene to friction so that the graphene is stripped, at the same time, blowing the exhaust sleeve through the blowing mechanism, so as to remove the graphene, collecting the inner part of the collecting sleeve ring, and through the discharging plate to rotate, collecting the dispersed graphene to discharge port, solving the problem that the graphene mechanical stripping and collecting is not convenient in the prior art.
