ZLJ-3 Automatic high precision air filling controller ,automatically inflatable controller for  film blowing machine, film extruder

This product uses infrared sensors 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 ,When 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.

Parameter specifications

Installation :

1,Installation: good connection inlet and outlet pipe , plug the sensor and power plug , plug in the power .

2,Ling adjustment : Turn the power switch, power indicator will light up. In the sensor between the launch tube and the receiver tube without something blocking the case , look at the spirit level indicator to indicate the status and transferred to light so far. Without light, spiritual degree potentiometer to \"+\" for the direction of rotation ; blinks , spiritual degree potentiometer to the \" - \"direction of rotation .

3,Throttle adjustments. In general, for a small size film or normal production, the throttle should be adjusted to be smaller to reduce the size of the film before and after inflation volatility , improve control accuracy . Specifications for bigger films or tensioned membrane , the throttle should be adjusted to be larger , so that bubble quickly fill to desired size , in order to reduce waste generation . Adjusting the throttle in an appropriate , by measuring the size of the film after inflation to judge. Under normal circumstances , more than the difference between1Cm , it should adjust small throttle .In production10Cm below the small size film, the throttle should be close shut , otherwise the size of the film will produce large fluctuations , namely a large , some small . To prevent this phenomenon, the tensioned membrane , it can open the throttle slightly , and hold the inflatable key ; when after blowing a large bubble and release the inflatable splint extraordinary character key and throttle shut small. After a while , the film will return to set the size dimensions
