Blown film machine in layman's terms is used with rice-sized particles, LLDPE or LDPE, (LLDPE is also known as linear, LDPE is also known as high-pressure, blown film of the two materials need to be mixed proportionately), and then ground, heated and melted, according to the size of the required production of plastic film, the finished product colour and lustre of the uniform, clean, bag stretching good. Here are some precautions for the use of film blowing machine:

Here are some precautions for the use of film blowing machine:

⒈ when operating the machine the operator can not stand in front of the front, so as to avoid accidents and injuries to the operator. Feed to prevent raw materials with metal impurities and operating small tools and other hard objects to damage the machine fell into the barrel. It is forbidden to wear gloves when operating the rotating machine in order to prevent from being involved in the injury.

Pake check and add reducer and air compressor lubricant, check the lubrication of mechanical transmission parts. Avoid dry operation to avoid damaging the machine and generating noise.

ã€€ã€€ã€€When starting the film blowing machine, check whether the power supply wiring is disconnected or leakage, and check whether the instrument is abnormally damaged. Ensure the normal specification of each part before starting, so as not to affect the production and cause accidents.

Singing Within the range of film forming conditions, increase the forming temperature, cold air temperature and inflation ratio, the film turbidity increases and the gloss decreases; vice versa increase.

Be careful when the material from the mould opening is even and consistent, put on gloves and pull up the billet slowly. At the same time, close the end of the billet, introduce the air inlet regulator valve slightly, put a small amount of compressed air into the mandrel centre hole and then carefully guide it through the foam stabiliser and herringbone plate, through the traction rollers and the guide rollers until winding (through the embossing rollers if embossing is required)

6. You can use to clean the film blowing machine and mould mouth with copper knife, copper rod or compressed air, but be careful not to damage the screw and the smooth surface of the screw.
