The production process of the film blowing machine is to first add the dry polyethylene particles into the lower hopper, and then the particles enter the screw from the hopper by their own weight. When the screw contacts the bevel of the thread, the rotating bevel face produces a thrust perpendicular to the bevel face of the plastic, pushing the particles forward. What should we pay attention to during normal operation? The following editor of Hengxiang Plastic Machinery will introduce it to you.

First of all, films that have not been corona treated or have not reached 38 dynes or more of corona treatment must not be put into the finished product, otherwise it will cause a major accident in the composite quality. The corona treatment machine guide roller must not be turned on without film moving. Once the film is broken or stopped, the corona treatment machine should be turned off urgently to avoid burning of the corona treatment machine. The guide rollers of the plastic film blowing machine, including rubber rollers and winding rollers, must not be cut with a blade, otherwise it will cause scratches on the guide rollers. Secondly, the filter screen of the extruder and the corona treatment machine should be replaced and cleaned regularly. It is generally required to replace the filter screen and clean the silicone roller of the corona treatment machine with alcohol within 24 to 48 hours. Specifications of the filter: a three-layer filter with two layers of 80 mesh and one layer of 100 mesh.

Again, when cleaning the die head and die mouth of the film blowing machine, only copper sheets can be used to clean the die mouth. Do not use a spatula or iron sheet to scrape the die mouth, otherwise it will cause damage to the die mouth. When unpacking the raw materials, check whether there is wet material. Wet materials must not be mixed. They can only be used after being dried in a drying room. If the equipment is not heated, the heating temperature and time do not meet the specified requirements, the extruder and rotating die head must not be started, otherwise the equipment will be damaged.
