1、 Characteristics:

1. The mold head can rotate around 360 degrees, which can enhance the strength and uniformity of plastic film.
2. Screw The material cylinder is made of 38CRMOALA alloy steel, which has undergone nitriding treatment and precision machining, with high hardness, strong corrosion resistance, and durability.
3. The die head is plated with hard chromium, and its structure is spiral core shaft type. The extruded molten material is uniform, and the blown film has good smoothness; The structure of the air cooling device is a maze type, with uniform air output. Using circulating water cooling to achieve optimal transparency of the blown film.
4. The winding device adopts pressure friction winding or center winding, and is adjusted by a torque motor. The winding is smooth and easy to change.

5. Selective configuration:

① Automatic suction machine

② Rotating die head

③ Double roll

④ Inflatable shaft

⑤ Processor

Usage:
1. Check that the temperature self-control is intact, the heating appliances are intact, and pay attention to timely adjusting the heating temperature at each point within the specified range.
2. Check the traction speed and control the film thickness.
Observe and adjust the uniformity of the film thickness, and ensure that the bending diameter meets the standard.
4. Check the pressure of the air storage cylinder, it should not be too high, but there should be a backup pressure.
5. Check and control the proportion of raw materials and mix them evenly.
⒍ Check for impurities in the raw materials, especially by promptly using a magnet to check for any iron mixed in.
7. Check the lubrication condition of the gearbox position and air compressor cylinder lubricating oil.
Regularly check the temperature rise and mechanical transmission of each operating motor.

2、 Purpose:

The polypropylene rotary die blown film unit is suitable for blowing polypropylene (PP) plastic film and is widely used in the packaging of household and industrial products such as food, clothing, textiles, and daily necessities.
