1、Film blowing machine double air outlet air ring is divided into: intake tuyere, air exchange body, rotating body, upper and lower outlet several parts.

2、Film blowing machine low pressure air ring air intakes, which are evenly distributed in the lower part or side of the air ring and connected to the fan air distribution bag through the air duct.

3、Film blowing machine double lip low pressure air ring is between the upper and lower tuyere, and the air flow is blown out 360 degrees. The tuyere is set at a certain Angle to control the contact Angle between the air flow and the membrane bubble.

4、Film blowing machine double lip low pressure air ring is fixed on the rotating body and can be rotated up and down to adjust the size of the outlet.

5、The efficient wind ring can significantly increase the output of the unit.

6、The film bubble formed by the blowing machine is in a molten state when it just leaves the touching head and needs to be cooled quickly. Otherwise, the membrane bubble will fall or adhere during winding, which will affect normal production.

7、In addition, the rapid cooling of the membrane bubble greatly improves the mechanical properties and optical properties of the film products.
