ABSTRACT:
A belt cleaning apparatus for cleaning continuous wide sanding belts which includes a belt drive assembly. The belt drive has a tensioning roller or bar which applies tension to the belt to be cleaned. A cleaning head with a spray nozzle reciprocates on a tracking lead screw to direct the spray against a belt surface as the belt rotates. Adjustable belt width sensing block cooperates with proximity switches on the cleaning head to conform travel to the belt width. Cleaning fluid is returned to a tank where the clogging material is allowed to either settle to accumulate on the fluid surface. Clarified solution is recycled and directed to the nozzle or returned to the tank via a heat exchanger unit.
