[0023] Working principle: When the present invention is used, when cutting the copper core of the cable, the copper core of the cable is placed on the cushion block 10, and then the electric push rod 4 is turned on, and the movable end of the electric push rod 4 drives the knife holder 16 to move downward, thereby driving the cutting knife 15 to move downward, and the cutting knife 15 and the cushion block 10 cooperate with each other to achieve the cutting of the copper core of the cable; Among them, due to the long-term use of the cutting knife 15, the blade will become blunt, so the cutting knife 15 needs to be polished, specifically: start the servo motor 6, so that the output shaft of the servo motor 6 rotates in the positive direction, and the output shaft of the servo motor 6 rotates in the positive direction to drive the screw rod 9 to rotate, thereby driving the threaded sleeve 8 to move upward, thereby driving the bar frame 29 to move (the moving position of the bar frame 29 can be recorded as: the initial position is A, the middle position is B, and the end position is C, wherein the position of point B is the position of the bar frame 29 when the bar tooth plate 28 is meshed with the gear 7), and the movement of the bar frame 29 is divided into two processes: Process 1: When the bar frame 29 moves from position A to position B, the movable block 39 moves upward with the bar frame 29 under the action of the extrusion spring 38, thereby driving the bar tooth plate 2 30 to move, thereby driving the gear 2 32 and the bidirectional screw rod 33 to rotate, and then the threaded sleeve 2 34 moves relatively under the action of the slider 37, thereby driving the connecting frame 22 to move relatively, thereby driving the grindstone 11 to move relatively, and further making the grindstone 11 contact with the cutting knife 15; When the grindstone 11 contacts the cutting knife 15, the bar-shaped tooth plate 2 30 will not move upward, while the bar frame 29 continues to move upward, so that the bar-shaped tooth plate 1 28 is meshed with the gear 1 7; The bidirectional screw rod 33 drives the winding wheel 12 to rotate when rotating, so that the traction rope 20 is wound around the winding wheel 12, and then the cushion block 10 is pulled to move, thereby driving the collection box 31 to move. When the grindstone 11 contacts the cutting knife 15, the collection box 31 moves to the bottom of the cutting knife 15 to collect the debris generated during grinding. Process 2: When the bar frame 29 moves from point B to point C, the bar frame 29 drives the bar toothed plate 1 28 to move upward, and then drives the gear 1 7 to rotate, thereby driving the connecting shaft 27 to rotate, and further driving the circular plate 24 to rotate. The rotation of the circular plate 24 drives the short cylinder 26 to rotate, and then drives the annular ring 13 to reciprocate, thereby driving the connecting rod 25 and the stabilizing plate 40 to reciprocate, and then under the action of the T-shaped slider 41, the connecting frame 22 reciprocates with the stabilizing plate 40, so that the grindstone 11 reciprocates with the stabilizing plate 40 to grind the cutting knife 15; and the debris generated by grinding will fall into the collection box 31; By controlling the output shaft of the servo motor 6 to rotate forward or reverse, the bar frame 29 is reciprocated between point C and point B, so that the grindstone 11 is reciprocated, so as to grind the cutting knife 15; When the cutting knife 15 is polished, the output shaft of the servo motor 6 is controlled to rotate in the opposite direction, so that the whetstone 11 is first moved to the rear end of the U-shaped frame 2, and then the whetstone 11 is moved to both sides, and the cushion block 10 is reset under the action of the reset spring 17.
