▎ 摘　　要

NOVELTY - The device has a motor for providing rotation power is fixedly installed at the bottom middle of a lifting plate. The top of a rotating column (7) is provided with a second groove (12). A connecting column (13) is fixedly installed at the bottom of the inner cavity of the second groove. A mounting grooves (14) are opened on all four sides of the outer wall of the connecting column. The inner cavity of the mounting groove is fixed with a second electric push rod (15). The outer end of the piston rod of the second electric push rod is fixedly connected with a rotating portion (16). The inner wall of the second groove corresponding to the rotating portion is provided with a through hole (17) adapted to the rotating portion. The rotating portion penetrates through the through hole. The outer end surface of the rotating portion is embedded with a distance sensor (19). USE - Processing device for graphene ultra-filtration membrane. ADVANTAGE - The device drives the clamping plate to clamp the carbon tube through two groups of third electric push rods so that different positions of the outer wall of carbon tube push the push rods at different positions in clamping process, thus the push rod compresses the spring. The push rods are matched with each other, so as to adapt the arc surface of outer wall to make clamping more stable and improve carbon tube clamping effect. The device drives the rotating sheet to extend through the second electric push rod in the process of extending, and the distance sensor can feed back the distance of the inner wall of a carbon tube when the threshold value is reached, thus ensuring that a rotating sheet is located at the best position of an inner wall. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a rotating column of the processing device for the graphene ultrafiltration membrane.
