What is ABA film blowing machine?

Film blowing machine adopts A, B double 45 host machine, to the head of the two main machines of the two materials forming three layers of film, ABA structure, blowing film strength, hard hand feel, good brightness, high yield, anti puncture ability is strong, and the middle layer can be mixed with cheap materials, reduce costs.

Film blowing machine adopts plastic-sprayed steel plate zigzag, new deceleration frequency conversion motor, new adjustable edge inserter, automatic air supply, LED photoelectric indicating device.

How to solve the difficulty of blowing film machine?

How to solve the difficulty of blowing film machine?

The film made of the film blowing machine can be widely used in light and weight packaging because of its good barrier resistance, fresh preservation, moisture prevention, frost resistance, oxygen separation and oil resistance. Film blowing machine is a common processing method of rubber and plastic machinery, so what are the common problems in the work of film blowing machine? Here is a partial workaround:

It is difficult to introduce models

Cause: improper nose temperature control

Solution: The nose temperature should be adjusted appropriately

Cause: uneven mouth is uneven

Solution: The mouth die gap should be adjusted along with the nose connector temperature

Cause: the melt contains coke impurities

Solution: purify the raw materials and clean the nose and screw

Cause: improper control of extrusion process conditions

Solution: the process conditions should be adjusted appropriately

 

The papers are uneven

Cause: the film thickness is uneven

Solution: Adjust the film thickness

Cause: the traction officer clamp force is uneven, the film deviation

Solution: adjust the clamping force to make the clamping force on the roller surface uniform

Cause: the air in the bubble tube is brought into the diaphragm, causing a wrinkle

Solution: adjust the clamping force, eliminate the gas in the membrane tube

 

The cream line is too high

Cause: Head temperature is too high

Solution: lower it appropriately

Cause: the extrusion volume is too large

Solution: reduce the screw speed appropriately

Cause of production: insufficient cooling

Solution: Increase the air volume of the cooling air ring

 

A little white or gum particles

Cause: there are impurities in the raw material

Solution: raw material screening

Cause: the filter screen rupture

Solution: switch to the filter screen

Cause: the particle mixture is uneven

 Solution: strict control of kneading and material manufacturing process

Most of the problems basically appear in the operation and process, and the film blowing machine is also divided into many kinds, including PE, POF, PVC and so on.
