NOVELTY - The utility model claims a graphene powder preparing device, comprising a first rotating shaft and a motor; the surface of the first rotating shaft is sleeved with a second gear; and the second gear is connected with a motor through a coupler; the bottom end of the motor is fixed with a base; and the top end of the base is fixed with a supporting rod; the supporting rod is connected with a second rotating shaft through a bearing seat; and the left side of the second rotating shaft is sleeved with a first gear; the right side of the second rotating shaft is fixedly connected with a connecting rod; and the connecting rod is hinged with a sliding block; the left side of the sliding block is matched with the swinging rod; the top end of the swinging rod is hinged with a feeding box. The utility model is provided with a gravity hammer capable of beating downwards and a feeding box moving back and forth, so that the graphene is subjected to force in different directions, so as to quickly damage the molecular structure, grinding into powder, by setting a screen, so that the prepared powder can be stored in the storage box by rolling of the gravity hammer, The invention greatly reduces the powder viscosity.
