The three-layer co-extrusion film blower checks and controls the proportion of raw materials and mixes evenly. In order to avoid accidental injuries to operators. When feeding, it is strictly prevented that hard materials with metal impurities and operating tools that damage the machine fall into the barrel. Never wear gloves when operating a rotating machine to prevent involvement. You can wear gloves and pull pipe blanks slowly.
At the same time, the end of the billet is closed and the intake control valve is slightly opened, so that a small amount of compressed air is put into the center hole of the mandrel, and then carefully guided through the foam holder and herringbone plate, and then penetrated into the traction roll, guide roll and coiled (if embossing is to be done through embossing roll). The function of the rotating nose is to make the film look good when the film thickness is uniform.
The film is continuously rotated at 360 degrees during blowing. The membrane circulates 360 degrees to eliminate the phenomenon of "bulging tendons" caused by the thickness of the membrane vesicles. The primary traction and splint are always stationary. Film blowing machine is to heat and melt plastic particles and then blow them into thin films. There are many kinds of film blowing machines, such as PE, POF, PVC and so on. The new material is blown out with brand new particles. The color is uniform, clean and the bag is well stretched.
Because it is suitable for blowing high density polyethylene, low density polyethylene and linear low density polyethylene plastic film, PE film blowing machine is widely used in the packaging of civilian and industrial products such as clothing, food, daily necessities, textiles and so on. We should wrap the cleaned cots in plastic film and place them in a dry, ventilated and cool place. Remember that the cots must be placed vertically or horizontally.
In addition, PE film blower cots should not be put together with corrosive substances. It will also cause the retention of raw materials. Five-zone discharging area, this link is very important, temperature and flow need to be strictly controlled, the whole heating process should be moderately controlled according to the outlet conditions, too high or too low will affect the film forming, five-zone equipped with blower, accelerate the film forming, and film thickness non-uniformity must be adjusted through film head reeling.
