▎ 摘　　要

NOVELTY - The device has a base (1) whose side is provided with a vertical plate (3). A top end of the vertical plate is hinged with two pawls (32) that are centrosymmetric and meshing to an inner ratchet wheel (31). An inner side end of a pawl is provided with an elastic sheet (33). Two outer surface ends of the internal ratchet wheels (31) are fixedly connected with an extending plate (34). An inner wall of the extending plate is slidably connected with a short guide rod (35). Ends of a scraper (37) are connected with a lower end surface of a corresponding short guide bar (35). A first spring (36) is sleeved on an upper end outer surface. An arc-shaped inclined surface is provided at the inner end of an arc. USE - Grinding device for processing graphene. ADVANTAGE - The device has low cost and high efficiency, and automatically cleans a grinding surface, saves manual cleaning operation, improves grinding fine quality, saves resource, and effectively avoids problem of grinding mechanism not fine enough and cleans a grinding surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a grinding method for processing graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a top side perspective view of a grinding device for processing graphene in partial section. 14Second rotating shaft 15Grinding cone 29Sleeve 30Sleeve plate 31Inner ratchet wheel 32Pawl 33Elastic sheet 34Extending plate 35Short guide rod 36First spring 37First scraper
