ABSTRACT:
A saw blade adjusting device of a band sawing machine includes an urging seat, an urging knob, an adjusting knob, a sliding seat, and a wheel frame. The urging seat has projections and depressions at a top end thereof, and the urging knob has urging portions projecting from a bottom side of an inner top end thereof, whereby the rotary adjusting motion of the urging knob is translated into an axial reciprocating urging motion. The relative abutment and separation of the urging knob and the urging seat is utilized to achieve tightening and positioning of a saw blade so that the tension of the saw blade and the distance between upper and lower wheel frames during violent cutting operation can be maintained stably to enhance the quality and efficiency of the cutting operation.
