AUTO BELT ADJUSTING SYSTEM-
Auto belt adjusting system - as shown in name of system it is used to adjust belt conveyor by itself by mean of solenoid valve and compressed air. This system is used for small length belt conveyor. This is very low cost system.
Working of auto belt conveyor system – as shown in attached photograph this system work on movement of flap and port change in solenoid valve.
According to first photograph as belt move in shown direction then flap move toward belt by action of spring, So port of solenoid valve change and air filled in mentioned below. By the action of air filled in below so roller housing with attached roller move from it position and as per rule of belt adjusting shown in attached photograph.
In second case during the operation of belt if belt move toward belt adjusting unit and press the flap downward then by the force of belt the port of solenoid valve change and air filled in second chamber and remove from first chamber and by the action of air filled the position of roller housing with roller change and rule shown in above the belt take its original position.
So it is very fine method of adjusting the belt by mode of air. This is very sensible equipment and by small movement of flap it takes action of adjustment and aligns the belt on its original position.
