What should be checked when installing an experimental blown film machine

The experimental blown film machine produces films, which are widely used in multiple fields according to different materials and characteristics. Do you know what checks should be performed on the equipment before installation?
For experimental blown film machines, when they cannot be used normally, it is very important to check whether the voltage of Type I blown film machine is normal, whether the air pump and air valve are normal and effective, and whether the circuits of each part are correct. Reasonable inspection and testing are also necessary. Check whether the oil level of the three gearboxes meets the standard, and promptly repair and handle any abnormal situations.
Check the power and electrical components, all parts should be grounded properly; Check whether the installation of the experimental blown film machine is in accordance with the requirements, and whether the bolts are tightened properly; Also, check the lubricating oil and air compressor in the gearbox; The lubricating material cylinder of various mechanical transmission components is not filled with plastic, but the temperature does not meet the requirements, so it is strictly prohibited to start; Check that there are no foreign objects in the cutting process, and that no iron filings or other harmful substances are mixed into the raw materials.
The heating system and temperature measurement system of the unit are in good condition during inspection; When starting, unrelated personnel should leave to prevent local overheating and burning of materials, to prevent belts and mixing drums from being punctured, and to prevent hair and clothes from getting tangled up; Small experimental blown film machines are generally divided into screw cooling, body cooling, and product cooling. The purpose of screw cooling is to eliminate frictional overheating, stabilize plastic extrusion pressure, promote uniform plastic mixing, and improve plasticization quality.
