CHECK AND INSPECTION
The discharging belt for this machine has the same structure as that for the conventional belt conveyor. Pay
attention to the following points, when starting the day's work or daily inspection.
Has the belt been biased or doe it make a snaky movement?
Is the belt tension appropriate?
Are debris stuck to the backside of the belt?
Has the belt surface been scratched or peeled off?
Has the belt scraper not been damaged?
Have metal parts or or bolts at the connetion of the belt end not been damaged or fallen off?
If anything unusual is found, take the following actions.
1) In case the belt is deflected or makes a snaky movement;
Adjust the position of the take-up unit, referring to the figure
at right. The take-up unit consists of a base plate, a pillow
block and a tap bolt. Loosen the lock bolt on the base plate
and adjust the position of the take-up unit with the tap
bolt.After the adjustment, tighten the lock bolt again. When
there is a clearance more than 10 mm (0.4 in) at both ends
from the inner surface of the flange at the end of the pulley,
the belt is at a proper position.
2) In case the belt tension is not appropriate;
Adjust the belt tension in the same way as mentioned
above. At that time, adjust the belt so that it will have a
clearance of 30 to 40 mm (1.2 to 1.6 in) from the lower
surface of the magnet on the main body.
3) In case debris are stuck at the backside of the belt;
Remove them as soon as found, since they can cause a
damage on the belt or the pulley.
4) In case the belt or any other relative parts is damaged;
Replace it with new one promptly.
