After the installation is completed, one end of the plastic part is installed on the winding roller, and the hydraulic rod 44 is started according to the actual situation to drive the scraper 47 at the bottom of the installation box 41 to descend. After the adjustment is completed, the driving motor 53 is started to drive the fixed winding roller to reel. During the reeling process, multiple exhaust fans 42 are started to deal with dust to ensure the physical and mental health of the staff. When cutting is required, the electric push rod 7 is started to drive the limit box 9 to descend. The descent of the limit box 9 drives the pressure plate 11 at the bottom of the installation box 8 to press the plastic part. When the cutter 14 reaches a certain height, the stepping motor 10 is started to drive the screw rod 13 to rotate. The rotation of the screw rod 13 drives the cutter 14 at the bottom of the movable block 12 to move horizontally, thereby realizing automatic cutting of the plastic part.
