Precautions for using PE film blowing machine

Dalian PE film blowing machine manufacturer summarizes the precautions for using PE film blowing machine for reference:

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

2. When operating the machine, the operator shall not stand in front to avoid accidental injury to the operator. During feeding, strictly prevent the hard objects that damage the machine such as metal impurities and operating gadgets in the raw materials from falling into the barrel. Do not wear gloves when operating the rotating machine to prevent injury caused by entanglement.

3. When starting up, check whether the power wiring of each circuit is disconnected and leakage; Check whether the instrument is damaged or abnormal. Before starting up, ensure that all parts are safe and normal, so as not to affect production and cause accidents.

4. When cleaning the extruder and die mouth, copper knife, rod or compressed air can be used for cleaning, but do not damage the screw and the smooth surface of the screw.

5. When the die discharge is uniform, wear gloves to slowly lift the tube blank, close the end of the tube blank at the same time, slightly open the air inlet regulating valve to put a small amount of compressed air from the central hole of the mandrel, and then carefully lead it through the foam stabilizer and herringbone plate, and thread it into the traction roller and guide roller until coiling (if embossing is required, it shall pass through the embossing roller)

6. The compressed air pressure of the expanded tube blank shall be appropriate, which can not break the tube blank, but also ensure the symmetry and stability of the membrane tube, so as to relatively ensure the production quality.

7. Within the range of film forming conditions, increase the forming temperature, cooling air temperature and expansion ratio; Then the film turbidity increases and the gloss decreases; On the contrary, improve.
