Automatic high precision air filling controller meter of film blowing machine parts

Overview :

This product uses infraredsensors to detect , only the sensor mounted on the outside of the film , the film will be able to automatically detect the size . Because it is non-contact detection of thin films using size perennial work so difficult to damage, and high accuracy. And the built-in solenoid valve and the throttle valve ( flow control valve ) , the mounting operation is very simple. Is ideal for blown film industry , is the best choice for replacement .

Main features:

1 ,The controllerA throttle valve , no longer applied , through the adjustment of the throttle can be reduced fluctuations in size of the film before inflation , so as to ensure consistent film width . Such films is wider, bigger air flow adjustable , whereas adjustable smaller.

2 ,W

hen the film is broken or less than the set value1MMSo when can automatically inflated ; if the film is not broken , then can quickly charge to the set value.

3 ,When inflation exceeds5Second is not sufficient to set value, then the automatic alarm to inform , indicating gas flow is too small or the film has been cut off .

4 ,OperatingPanelPneumatic control with manual twist .

5 ,A sensitivity indicator , can indicate low , normal and high ( LED flashes )3States.

6 ,The entire control circuit , throttle , solenoid valves are mounted within the instrument in the control , the operation is very simple and convenient.

7 ,Using infrared film on the radio way to detect the size of solved due to mechanical switch detects insufficient brought (BF-I complement wind controller is a mechanical switch ) .

8 ,The products imported MCU intelligent control , solved due to misuse film jitter generated inflation . The control more accurate.
