▎ 摘　　要

NOVELTY - The device has a working table (16) whose top end is provided with a stage (5). A top end of the working table is fixed with a frame portion (6). An inner side wall of the frame body is provided with a sliding structure (12). An outer side wall of the sliding structure is provided with a convex block (8). A bottom end of the frame poriton is provided with a lifting mechanism (7). A bottom end of the frame body is fixed with a material roller (9). A bottom end of the frame body is installed with a material box (11). A top end of the working table is fixed with a supporting column (15). USE - Production equipment based on graphene modified SMC unit. ADVANTAGE - The device is provided with the fixing structure in the first material roller and the second material roller, so that the material roller is convenient to change the material when loading and unloading. The bolt block drives the screw rod to rotate. The screw rod is transmitted to the notch in the second material roller to finish the fixing of the second material roller. The material roller is placed to fall off. The feeding and discharging of the material roller is made more convenient and saves labor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the production equipment.
