Chinese patent number is the waste selvage scissors that 00202579.5 utility model patent specification discloses a kind of Rapier looms; Knife rest is provided with fixed cutter body; Be provided with power transmission shaft in the axis hole of knife rest; The one of which end is associated with movable cutter hub, is close proximity to the fixed cutter body outside, is associated with driving lever on the power transmission shaft and is provided with spring.The movable cutter hub of above-mentioned utility model rotates under external force with fixed cutter body and cooperates completion to shear, and after external force disappears, utilizes the torsion of spring, and movable cutter hub resets, and this is resetting of a kind of passive type.After long-time the use, can influence shear action, thereby cause the slitter edge shearing motion to lose efficacy because of spring fatigue.Reset if can continue that the movable cutter hub application of force is carried out movable cutter hub, promptly adopt resetting of active type, then can avoid above-mentioned and take place because of spring fatigue causes slitter edge shearing motion failure phenomenon by the external force of accomplishing shear action.
The utility model content
The purpose of the utility model is to propose a kind of waste selvage scissors device that adopts the Rapier looms that active type resets.
For achieving the above object, the utility model is taked following technical scheme.
The waste selvage scissors device of the Rapier looms that the utility model proposes comprises fixed cutter body and movable cutter hub, and the front portion of fixed cutter body and movable cutter hub is respectively equipped with blade; Said fixed cutter body is fixed on the frame, and movable cutter hub front portion is in the anterior outside of fixed cutter body, it is characterized in that: also comprise the power transmission shaft by rack support; Be connected with eccentric bushing on the said power transmission shaft; The outside of eccentric bushing is connected with drive through bearing, is fixed with a driving member on the end face of drive, and the top of driving member is provided with the upper pin hole; The rear portion and the middle part of movable cutter hub are respectively equipped with rear pin shaft hole and middle pin shaft hole; Be provided with first bearing pin in the middle pin shaft hole of movable cutter hub and the upper pin hole of driving member, movable cutter hub and driving member formed be dynamically connected, the rear portion of said fixed cutter body is the U-shaped shank; Respectively be provided with the rear pin shaft hole on the inner and outer wall of formation U-shaped shank; Insert between the inside and outside wall of fixed cutter body at the rear portion of said movable cutter hub, by the rear pin shaft hole of second bearing pin through rear pin shaft hole on the inside and outside wall of fixed cutter body shank and movable cutter hub both is dynamically connected, on second bearing pin and be between the outer wall of movable cutter hub and fixed cutter body shank and be provided with spring.
Be provided with oscillating bearing in the pin shaft hole of said driving member, first bearing pin inserts in the oscillating bearing.
The utlity model has following good effect: in this device; The motion of movable cutter hub is by not stopping rotating drive shafts; Drive driving member through the eccentric bushing on it, bearing, drive and produce continuous reciprocating motion, thereby drive activity cutter hub is made shearing and reseting movement continuously, through spring the gap between movable scissors and the fixed blade is adjusted; So the utility model is simple in structure, the slitter edge shear action is continuous, stable, reliable.
