Matters needing attention in the operation of film blowing machine


The film blowing machine heats and melts plastic particles and then blows them into a film. There are several things to note during operation:


⒈ Operators should not stand directly in front of the machine to avoid accidental injury to the operator. When feeding, strictly prevent the metal impurities in the raw materials and the operation of small tools and other hard objects that damage the machine from falling into the barrel. It is forbidden to wear gloves when operating the rotating machine to prevent getting involved and being injured.


⒉ Check and add lubricating oil in the reduction gearbox and air compressor, and check the lubrication of each mechanical transmission component. Avoid dry operation to damage the machine and make noise.


⒊ When starting up, you must first check whether the power supply wiring of each channel is disconnected or leakage; check whether the instrument is damaged or abnormal. Before starting the machine, make sure that all components are safe and normal, so as not to affect production and cause accidents.


⒋ In the range of film-forming conditions, increase the molding temperature, cooling air temperature and inflation ratio; then the film turbidity increases and the gloss decreases; vice versa.


⒌ When the discharge at the die mouth is uniform, you can wear gloves and slowly pull the tube blank, at the same time close the end of the tube blank, slightly open the air inlet adjustment valve, so that it puts a small amount of compressed air from the center hole of the mandrel, and then be careful Lead through the foam stabilizing frame and the herringbone board, and pass into the traction roller and guide roller until it is taken up (if the embossing needs to pass the embossing roller)


⒍ The compressed air pressure of the inflated tube blank must be appropriate, which can not only rupture the tube blank, but also ensure the symmetry and stability of the membrane tube, which relatively guarantees the quality of production.


⒎ You can use copper knives, rods or compressed air to clean the extruder and die, but do not damage the screw and the smooth surface of the screw.


Correct operation of the film blowing machine has a huge impact on the life of the machine.
