[0024] The label is transmitted to the connecting roller 6 through the label roller 2, and then the cutting is completed by the cutting roller 7. The surface of the cutting roller 7 is provided with a plurality of cutting knife seats 8. The spacing between the two cutting knife seats 8 can be determined according to the width of the label roller 2 to be cut. Finally, the rotating motor 17 and the micro-electric telescopic rod 18 are started to drive the cutting roller 7 and the cutting knife seat 8 to rotate, and the entire cutting roller 7 is moved downward to complete the cutting of the label. When it is necessary to change the spacing between the two cutting knife seats 8, the arc electromagnetic block 20 is powered off so that it is no longer adsorbed on the inner wall of the cutting knife seat 8 through the groove 9, and a spring is provided inside the sleeve rod 19, which drives the arc electromagnetic block 20 to reset. At this time, the cutting knife seat 8 can be moved. After determining the position, the arc electromagnetic block 20 is powered on. The elastic force of the spring is less than the magnetic force of the arc electromagnetic block 20, so that the arc electromagnetic block 20 is adsorbed on the inner wall of the cutting knife seat 8 to complete the positioning of the cutting knife seat 8.

Finally, the rotating motor 17 and the micro electric telescopic rod 18 are started to drive the cutting roller 7 and the cutting tool holders 8 to rotate, and the entire cutting roller 7 moves downward to complete the cutting of the labels. When it is necessary to change the distance between two cutting tool holders 8, at this time, after the arc-shaped electromagnet 20 is powered off, it no longer adsorbs on the inner wall of the cutting tool holder 8 through the groove 9. And a spring is arranged inside the sleeve rod 19, and the spring drives the arc-shaped electromagnet 20 to reset. At this time, the cutting tool holder 8 can be moved. After determining the position, the arc-shaped electromagnet 20 is powered on. The elastic force of the spring is less than the magnetic force of the arc-shaped electromagnet 20, so that the arc-shaped electromagnet 20 adsorbs on the inner wall of the cutting tool holder 8 to complete the positioning of the cutting tool holder 8. Through holes are provided on one side of the fixed frame 4 and the cutting roller 7 to facilitate the connection of wires to the arc-shaped electromagnet 20.
