PE film blower is very important for judging the fault of transmission. If a gear goes off, it must be related to the parts that affect the transmission of the gear. If all the gears go off, it is often the fault of the gear shaft in constant mesh or the oil shortage of the transmission. Whether it is related to specific actions, such as adding, reducing gear, starting, accelerating, decelerating and turning, are all effective means of judging abnormal sound. Among them, changing speed and direction is particularly important for judging rear axle fault.
The exhaust fan discharges the hot air from the membrane bubble, and the gas inside and outside the membrane bubble is continuously exchanged to achieve a dynamic balance. If there is no internal cooling and exhaust air, more and more air will be in the membrane bubble, leading to no winding, the air must be consistent in and out. The diaphragm head is directly related to the chassis of the wind ring. The corresponding diaphragm head should be equipped with the chassis of the wind ring, such as 80 mm diaphragm head with 630 wind ring or 800 wind ring, but the chassis of the wind ring is different.
The thicker side is tightened up. This is called inversion. There are four or six adjusting bolts in the die head, which are usually hexagonal. At the upper edge of the die, they can be adjusted. As for the tightness or looseness, different moulds from different origins are different, it is necessary to know after operation. That is to say, it can lubricate the screw die head and play the role of clearing the mould. Blow ratio is too large, easy to operate, and the uniformity of product thickness is difficult to control. For LDPE, the general control is 1.5-2.5.
It is advisable to control HDPE between 3 and 6. Generally, HDPE special film blowing units of type 40 and 55 are used. Bag-making machines are hot-sealed and cold-cut bagging machines or coiled bagging machines. One film blower can be equipped with two bagging machines. The finished product is well stretched. If plastic particles are made from recycled waste plastics.
Pigments are usually added to the films. The films may be unevenly colored, brittle and fragile, and the price is low. If the non-professional blower or blower does not use the correct method in the processing, then the film material may be inferior. HDPE film is often used in commodity bags, grocery bags and food packaging. PE film processing is usually done by ordinary blowing or flat extrusion.
