About the Use of Blowing Film Machine

Use a torque wrench to remove the mold screws and operate according to the specified torque. Molybdenum disulfide grease is used as a lubricant for high-temperature screws. The mold cannot be welded or cut. Wind coil maintenance: Clean up debris and dust from the wind coil in a timely manner. Maintenance of traction device: The herringbone folding is pollution-free, the gripping traction (cooling) roller pressure is moderate, there is no condensation water, and the telescopic roller pressure is flexible. Repair corona generator: Regularly clean high-voltage transformers, discharge rollers, discharge racks, and cabinets, and adjust discharge gaps; Check the humidity of the equipment to avoid short circuits in the discharge rack before starting up. Check the working temperature of the discharge roller bearings and replace the silicone hoses in a timely manner. After vacation, production workers gradually return to work and carry out new production tasks. However, before starting up, the following inspections should be carried out: first, check whether the joints of the film blowing machine are tight to prevent bolts from loosening; Secondly, the main engine gearbox and traction reducer should be regularly refueled and the gear oil should be replaced (the oil level can reach the mark) to ensure the normal operation of all rotating components and prevent difficulties in operation and overheating damage; Dalian Blowing Film Unit

When starting the main engine, the motor should be started first, and then slowly accelerated until the required speed is reached before it can stabilize; If the machine is shut down for maintenance, it should be slowed down first and then shut down; If preheating, the heating time should not be too long, nor should it be too long, to avoid blocking the feeding port; When conditions permit, an automatic temperature control system can be used to set upper and lower tolerances, ensuring automatic stability and convenient safety; After the host is turned on, closely monitor its operation, adjust and correct electrical instruments and controllers in a timely manner, observe for abnormalities or damage, and repair and replace it to ensure its normal operation; It is strictly prohibited to rotate without material. When the cylinder, tee, and mold do not reach the required temperature, the main engine cannot be started; The compressed air inside the bubble tube should be kept balanced, as it may leak during traction, thus achieving timely replenishment.
