The operation of professional three-layer co-extrusion film blowing machine or multi-layer co-extrusion film blowing machine also need to pay attention to some matters:

First of all, an important point is that when operating the machine, the operator can not stand in front of the machine, so as to avoid machine accidents, causing damage to the operator, and in the feed, it is prohibited to raw materials containing metal impurities and other hard objects that will damage the machine into the barrel, and when operating the rotating machine, it is prohibited to wear gloves, to prevent being involved in the machine and injured.

Secondly, before the operation, we should check and add the lubricating oil in the reducer and air compressor, and check the lubrication of the mechanical rotating parts to avoid the parts being too dry to damage the machine and make noise. At the same time, we must check whether the power wiring of the three-layer co-extruded film blowing machine is disconnected, leakage, and whether the instrument is damaged. Before the operation, we should ensure the safety and normal of each part. So as not to cause production accidents.

Furthermore, to improve the temperature of forming, the temperature of cooling air and the blowing ratio in the range of film forming conditions, and when the film buckle discharge uniformly, it is necessary to wear good gloves to slowly pull the tube blank, and at the same time the port is closed, slightly open the intake regulating valve, so that the mandlet center hole into a small amount of compressed air, and then carefully lead the stable bubble frame, the miter plate, And through the traction roller, guide roller until winding, blowing the tube billet compressed air pressure should be appropriate, not only can not make the tube billet crack, but also to ensure the symmetry and stability of the film tube, relatively ensure the quality of production.

After the operation is completed, when the extruder and die of the three-layer co-extruded film blowing machine need to be cleaned, copper knife, rod or compressed air can be used to clean the work, but do not damage the screw and the surface of the screw, keep the surface clean.
