APPARATUS FOR CONTROLLING GAP BETWEEN CUTTING EDGES OF ROTATING BLADE AND FIXED BLADE IN SHREDDER

摘要

PURPOSE: To facilitate adjustment of a gap between cutting edges of cutting parts of a rotating blade edge and a fixed blade edge by arranging movably the fixed blade in parallel in the tangential direction to the circular arc of the rotating blade. ;CONSTITUTION: A fixed blade 11 is minutely adjusted by screwing adjusting bolts 8A and 8B in the tangential direction of the cutting edge rotating orbital circle so as to make the gap between cutting edges of the fixed blade 11 and a rotating blade 3 appropriate. By the way, to move forward or backward the cutting edge of the fixed blade by about 0.3mm in the radial direction to the cutting blade of the rotating blade 3, it is necessary to move forward or backward the cutting blade of the fixed blade 11 by about 6.7mm in the tangential direction. In order to do it, the screw of a module should be rotated by 4.5 turns to result in easier operation of adjustment of rotation than before. In addition, a flow-down guiding plate in a hopper on the opposite side to the fixed blade 11 fixing side of the hopper 10 is opened to a discharging orifice 13 for hard foreign substances B mixed in an article C to be shredded.;COPYRIGHT: (C)1996,JPO
