▎ 摘　　要

NOVELTY - Graphene powder production device comprises a box body (1), where a first electric motor (3) is fixedly mounted on one side of an outer wall of the box body, and the inside of the box body is provided with active roller (4), screen body (7), screen (8) and casing from top to bottom. The bearing of the first motor output shaft passing through one side of the inner wall of the casing is fixedly connected with one end of the active rolling roller. The other end of the active roller is movably connected with a bearing embedded on the other side of the inner wall of the casing, and one side of the active rolling roller is meshed with a driven rolling roller. The bottom end of the active rolling roller is fixedly provided with a first funnel, and the bottom end of the first funnel is fixedly provided with a bearing. The bottom end of the first funnel is fixedly connected with the bearing inner ring, the top end of the screen body is fixedly connected with the bearing outer ring. USE - Used as graphene powder production device. ADVANTAGE - The device ensures that the delivered graphene powder meets the requirements, and can continuously produce graphene powder. DETAILED DESCRIPTION - Graphene powder production device comprises a box body (1), where a first electric motor (3) is fixedly mounted on one side of an outer wall of the box body, and the inside of the box body is provided with active roller (4), screen body (7), screen (8) and casing from top to bottom. The bearing of the first motor output shaft passing through one side of the inner wall of the casing is fixedly connected with one end of the active rolling roller. The other end of the active roller is movably connected with a bearing embedded on the other side of the inner wall of the casing, and one side of the active rolling roller is meshed with a driven rolling roller. The bottom end of the active rolling roller is fixedly provided with a first funnel, and the bottom end of the first funnel is fixedly provided with a bearing. The bottom end of the first funnel is fixedly connected with the bearing inner ring, the top end of the screen body is fixedly connected with the bearing outer ring, and the top plate of the mesh plate is fixed with a sliding plate. Multiple sliders are fixedly disposed at a bottom end of the screen body are slidably connected with an annular sliding slot provided on the sliding plate, and the bottom of the mesh plate is fixedly mounted with two electric motors. The output shaft of the second motor is fixedly connected to the center of the bottom of the screen body through a circular hole opened in the center of the screen plate, and a second funnel is arranged at the bottom end of the screen plate. The bottom end of the second funnel is fixedly connected to the top end of the casing. The bottom end of the casing is fixedly connected to the bottom end of the inner wall of the casing through multiple support columns, and a third electric motor is fixedly mounted at the center of the bottom of the casing. The output shaft of the third motor is fixedly connected to the bottom end of the stirring rod provided inside the casing through the casing wall of the casing, and the stirring rod is provided with many short rods, and the bottom end of the box body is equipped with a fan, and the air outlet of the fan connected with the inside of the casing through a duct.
