Abstract: A sawdust collection system includes a sawdust duct secured in a saw blade housing and having an enlarged portion formed on a front end thereof. A sawdust chute is partially pivotally received in a lower portion of the enlarged portion of the sawdust duct such that the sawdust chute can be swung relative to the sawdust duct. A first stopper laterally outwardly extends from a bottom of the sawdust chute and a torsion spring is mounted between the sawdust duct and the sawdust chute to prevent the sawdust chute from a vibration during operating. A second stopper laterally outwardly extends from a top of the sawdust chute. The second stopper selectively abuts a distal edge of the enlarged portion for limiting the moving range of the sawdust duct.

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.
