Features of air supply controller for film blowing machine
1. A throttle valve is provided. By adjusting the throttle valve, the fluctuation of film size before and after inflation can be reduced, so as to ensure that the width of the film remains consistent. For example, if the film is wider, the air flow can be adjusted larger, otherwise it can be adjusted smaller.
2. When the film is broken or less than the set value, it can be automatically inflated; if the film is not broken, it can be quickly inflated to the set value.
3. When the inflation exceeds 3 seconds and the set value is not filled, an automatic alarm will be issued to inform that the air flow is too small or the film has been broken.
4. A manual inflation control knob is provided.
5. A sensitivity indicator light is provided, which can indicate three states: too low, normal and too high.
6. The entire control circuit, throttle valve and solenoid valve are installed in the controller, making the operation very simple and convenient.
7. The infrared beam is used to detect the size of the film, which solves the shortcomings caused by mechanical switch detection (the BF-1 air supply controller uses a mechanical switch).
8. This product adopts single chip intelligent control to solve the problem of mis-inflation caused by film shaking, making the control more accurate.
