Now, in the new development situation, the original high energy consumption and high pollution production methods are difficult to maintain. If the film blowing machine market can not optimize the industrial structure, technological innovation and development with the development of the market, it will only be eliminated by the market. The following are the precautions to take before starting the film blowing machine
　　1、Check whether the unit installation work is installed as required and check whether the bolts are well fastened.
　　2、Check whether the traction motor is working normally, check whether the winding component torque motor is working normally, and check whether the cooling fan and wind ring are working normally.
　　3、Check and add the lubricant of reducer and air compressor, check the lubrication of transmission parts of film blowing machine.
　　4、Check the power supply and electrical parts, all parts should be safely grounded.
　　5、Check whether the oil of all parts of the film blowing machine is sufficient, focusing on the lubrication of the gear box.
　　6, the gas cylinder is not full of plastic, full of plastic and the temperature does not reach the requirements, it is strictly prohibited to start.
　　7、Check that there can be no foreign objects under the material, raw materials must not have iron filings or other unqualified materials mixed in.
　　8, the material requirements should be dry, otherwise it should be pre-dried.
　　9, check whether there are foreign objects in the screw hopper, if there are foreign objects or hard objects such as iron chips gravel, etc. must be cleaned.
　　10、Check whether the heating system and temperature measurement system of the film blowing machine are intact.
　　11、Unrelated personnel should leave when starting to prevent local overheating and burning of the material, prevent injury to the belt and mixing barrel, and prevent hair and clothing entanglement.
　　The above is the content of this introduction, after completing all the above film blowing machine inspection steps can be normal production of film.
