Daily maintenance ensures stable operation and extends lifespan. Daily: Clean the equipment surface, sealing and cutting blades, and heating chamber; remove film debris and dust; check conveyor belt tension and deviation; check temperature control and speed display for normal operation. Weekly: Lubricate guide rollers, chains, bearings, and other transmission components; check sealing and cutting blade wear and the integrity of high-temperature adhesive tape; test emergency stop and limit switches. Monthly: Check heating tubes and wiring for aging or loosening; calibrate temperature control accuracy; clean fan outlets and air ducts; check cylinder and air pipe sealing. Quarterly: Replace aging seals and worn conveyor belts; conduct a comprehensive inspection of electrical components; test motor operating current. Also, store film materials properly, ensuring dryness, ventilation, and avoiding exposure to sunlight and moisture. Establish maintenance records and promptly address any abnormalities.
