Precautions for using film blowing machineDate:【2020-07-15】 Read【239】Times 【Print】 【Back

1. The operator should not stand directly in front of the machine to avoid accidental injury to the operator. When feeding, strictly prevent the metal objects 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 caught and injured.

 

2. 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.
 

3. When starting up, you must first check whether there is any disconnection or leakage in the power supply wiring; check whether the instrument is damaged or abnormal. Before starting the machine, ensure that all components are safe and normal, so as not to affect production and cause accidents.


4. Within the range of film forming conditions, increase the molding temperature, cooling air temperature and inflation ratio; then the film turbidity will increase and the gloss will decrease; vice versa.

 

5. 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 intake adjustment valve, so that it puts a small amount of compressed air from the center hole of the mandrel, and then Carefully lead through the bubble stabilizing frame and the herringbone board, and pass into the traction roller and guide roller until it is taken up (if you want to emboss, you need to pass the embossing roller)

 

6. The compressed air pressure of the inflated tube blank must be appropriate, not only to not break the tube blank, but also to ensure the symmetry and stability of the film tube, which relatively guarantees the quality of production.


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