Abstract:
1. A cutting apparatus for a conveyor belt, the cutting apparatus comprising: an elongate upper clamp member for extending across the conveyor belt; an elongate lower base member for extending across and below the conveyor belt to support the belt on the elongate lower base member; a clamping mechanism for shifting the upper clamp member down and the lower base member relative to each other in a clamping direction toward each other for clamping the conveyor belt between the elongate upper clamp member and the elongate lower base member; a cutting blade mounted to the lower base member for cutting the clamped conveyor belt; a screw drive mechanism of the clamping mechanism operable to shift the upper clamp member and lower base member in the clamping direction for generating a clamping force on the conveyor belt; an end linkage assembly including outboard and inboard pivot connections for pivotally connecting the lower base member, the screw drive mechanism, and the upper clamp member together; and a screw drive shaft of the screw drive mechanism between the outboard and the inboard pivot connections, wherein the end linkage assembly has an elongate pivot linkage extending between the outboard and the inboard pivot connections to pivotally connect the pivot linkage to both the lower base member and the upper clamp member with the elongate pivot linkage having a length and being pivotally connected to the screw drive shaft at an intermediate location along the length of the elongate pivot linkage.
