Correct operation steps and precautions of film blowing machine

news

Check whether the installation of the unit is properly installed according to the requirements, and check that the bolts are properly fastened.
Check and add the lubricating oil in the gear box, air compressor, and check the lubrication of each mechanical transmission component.
Check the power supply and electrical parts, and each machine should be safely grounded.
If the barrel is not filled with plastic and the temperature is not up to the requirement, it is prohibited to start.
Check that there are no foreign bodies in the materials, and no iron filings or other unqualified materials in the raw materials.
The material should be dried, otherwise it should be pre-dried.
Check that the heating system and temperature measuring system of this unit are in good condition.
During the boot process, irrelevant personnel should leave, to prevent local overheating out of the material burn, to prevent belt and mixing tube injury, to prevent hair, clothes from being rolled into.

Normal steps of film blowing machine:
Heat the extruder unit, die head unit and control the temperature of each point within the index.
Running film blowing machine after a long stop, the heating temperature of each point needs constant temperature for 10-30 minutes after reaching the target range. If plastic film blowing machine is shut down within half an hour, there is no need for constant temperature.
Start the air compressor and stop when the pressure of the storage cylinder is 6-8kg /cm.
According to the film fold diameter, thickness requirements and extruder production capacity of processing, estimated traction speed and bubble diameter.
After the temperature of each point reaches the target and meets the requirements, wear labor protection supplies and start the tractor, blower and extruder in sequence.
When the die mouth output is uniform, you can wear gloves and slowly pull the tube blank, at the same time, close the end of the tube blank, slightly drive into the gas regulating valve, so that a small amount of compressed air is blown into the center hole of the mandrel, and then carefully lead over the stable bubble frame, lambdoidal board, and into the traction roll and guide roll until the winding.
Check the film thickness, width, and adjust to meet the requirements.
