As a preferred embodiment of the invention, by arranging the first clamping heads 8637 with the corner slots 8639 at both ends, the positions of the first clamping heads 8637 and the second clamping heads 8638 for clamping the sheath cable are at the sides of the sheath cable far away from the functional wheels 861, so that the clamping position of the first clamping heads 8637 is closer to the axis of the sheath cable, the connecting distance between the clamping points of the two symmetrical first clamping heads 8637 is greater than the connecting distance between the clamping points of the two symmetrical second clamping heads 8638, and when the first clamping heads 8637 and the second clamping heads 8638 clamp the sheath cable, the first clamping heads 8637 need more deformation, and the corner slots 8639 at both ends of the first clamping heads 8637 are arranged so that the first clamping heads 8637 are easier to deform.
Working principle: the method comprises the steps that a core wire is detected to be defective by a front-end power frequency spark mechanism 7, a signal is sent to a damage mechanism 8, the length from a power frequency spark machine to the damage mechanism 8 and length parameters to be damaged are set before an external system works for calculating the position from the defective core wire to the damage mechanism 8, when a defective wire reaches the position of the damage mechanism 8, an external system starts a cylinder 82 to drive a blade wheel 84 to squeeze a sheath cable, the movement of the sheath cable drives the blade wheel 84 to rotate, the blade wheel 84 cuts the sheath of the sheath cable to expose an inner conductor to prepare for the detection of the defect position of a rear-end power frequency spark machine, equipment is automatically reset after the sheath cable is damaged for a certain length, and when the rear-end spark mechanism 7 detects the pressure-resistant defect of the sheath, the signal is sent to a wire cutting mechanism 5; the wire cutting mechanism 5 stops cutting wires and the wire taking mechanism 10 stops taking wires, when the defect sheath completely passes through the wire cutting equipment, the wire cutting mechanism 5 cuts off waste wires, the wire taking mechanism 10 is started in a delayed mode, the motor 99 of the wire storage mechanism 9 is started by a system sending signal, the output shaft of the motor 99 drives the screw rod 95 to rotate, the sliding seat 96 is caused to slide along the functional groove 94, the position of the second wire guide wheel 97 is changed along with the sliding seat, the wire storage distance between the second wire guide wheel 97 and the third wire guide wheel 98 is prolonged, and the accumulation of cables is avoided. Since the wire takeout mechanism 10 does not activate the scrap wire, the defective sheath cable is removed from the scrap wire area by the conveying mechanism 6 and does not remain in the finished product area.
The embodiments of the present invention are disclosed as preferred embodiments, but not limited thereto, and those skilled in the art will readily appreciate from the foregoing description that various modifications and variations can be made without departing from the spirit of the present invention.
