General Introduction
This "air supplementary controller" is a modular system to measure and control the lay flat width on blown film lines. BF-1 uses a mechanical switch to detect the size of the film, with a separate controller and solenoid valve.
The BF-1 type film blowing machine air supply controller could also choose to use proximity switch (approach switch) induction, so as to avoid the trouble of the traditional optical coupling type being easily affected by dust and requiring repeated cleaning.
Working Principle
The Diagrammatic Map
During the blowing process, the air leakage could make the film narrow, then the transducer close to the film will feedback this signal to the main controller, and open the electromagnetic valve to feed air to mould with the alarm, until the film's width is normal, then close the electromagnetic valve and stop alarming.
