Abstract
A conveyor belt tensioning mechanism for use with a conveyor having a frame, a conveyor member in the form of a belt, and a pair of rollers, includes a pair of tensioning members mounted to opposite sides of the conveyor frame, with one of the rollers being mounted to the tensioning members. The tensioning members are slidable between extended and retracted positions by means of a pair of fasteners extending through a slot formed in each tensioning member and interengaged with the frame via a locking sleeve. The fasteners extend through a locking plate, such that tightening the fasteners frictionally engages the tensioning member between the frame and the locking plate. The belt is tensioned by loosening the locking fasteners and engaging a tensioning tool with the frame adjacent each tensioning member. The tensioning tools are pivoted into engagement with the tensioning members, and include a cam surface which forces the tensioning members outwardly to an extended position for tensioning the belt. The locking screws are then tightened to maintain the tensioning members in the extended position. Belt tracking can be adjusted utilizing a cam member mounted to the tensioning member, which is engageable with the end of the frame side wall.
