The copper wire 7 is located in the upper middle part of the rotating shaft 18. By energizing the copper wire 7, the temperature of the copper wire 7 after energization is high, and the high temperature is used to cut the corrugated tube. No burrs will be generated after the incision of the corrugated tube is hot-melted, and no waste chips will be generated during the cutting process. The bottom end of the lifting screw rod 4 is connected to the power output end of the screw motor 5 through a flange.

[0022] As a further implementation scheme of the above technical scheme: a guide wheel 8 is installed at the rear end of the cutting table 1, and the extruded corrugated tube can be introduced into the cutting table 1 through the guide wheel 8, and the guide wheel 8 plays a guiding role.

[0023] As a further implementation scheme of the above technical scheme: two groups of rotating shafts 18 are arranged in parallel, and the rubber pads 9 are glued and fixed to the surface of the rotating shaft 18, and a certain gap is left between the two groups of rubber pads 9, and the gap between the rubber pads 9 can be used for the copper wire 7 to cut the corrugated tube.

[0024] As a further implementation scheme of the above technical scheme: the gap between the two groups of rubber pads 9 is adapted to the position of the cutting groove 2, and the vertical center line of the cutting groove 2 and the copper wire 7 are located in the same vertical plane. The copper wire 7 can enter the cutting groove 2 during the descending process, thereby cutting the bottom of the corrugated tube.

[0025] As a further implementation scheme of the above technical scheme: the cutting groove 2 is connected to the roller mounting groove 3, the positions of the two sets of clamping mechanisms and the rubber pad 9 are adapted to each other, and the clamping mechanism can clamp and fix the corrugated tube placed on the rubber pad 9.

[0026] As a further implementation scheme of the above technical scheme: the clamping mechanism includes a clamping plate 13 slidably installed on the top of the cutting table 1, and a limiting slide groove 11 is provided at the connection between the clamping plate 13 and the cutting table 1, a limiting slider 15 is arranged inside the limiting slide groove 11, and the limiting slider 15 is fixed on the clamping plate 13, and an electric push rod 14 is arranged on one side of the limiting slider 15, the limiting slider 15 and the limiting slide groove 11 can guide the clamping plate 13, and the electric push rod 14 can push the clamping plate 13 to move in the direction close to the roller mounting groove 3, so as to facilitate the clamping of the corrugated tube.
