Then the operator The operator then continues to drive the electric telescopic rod 3 to push the entire rubber tube 5 to slide along the inner wall of the guide groove 101 toward the cutting mechanism 12, and at the same time runs the electric heating wire 102 in the inner wall interlayer of the guide groove 101 to heat it up and preheat the rubber tube 5 placed inside the guide groove 101, so as to improve the hardness and toughness of the rubber tube 5 and enhance the cutting effect and accuracy. During this period, the operator can inject clean water into the water guide pipe 1002 through an external water pipe, so that the clean water enters the inside of the return pipe 1003 and sprays it from its pipe mouth when flowing through the spray pipe 1004. The liquid is evenly sprayed onto the surface of the rubber tube 5 placed inside the guide groove 101, thereby cooling and dissipating the heat, and preventing the rubber tube 5 from being deformed or damaged due to overheating. At the same time, the electric telescopic rod 3 will keep pushing the rubber tube 5 to move forward intermittently to the top of the U-shaped knife groove 6, and the cutting blade 1203, driven by the hydraulic cylinder 1201, passes through the through groove 701 opened on the top of the protective cover 7, and continuously and automatically cuts the rubber tube 5 placed on the top of the U-shaped knife groove 6 downward, and the cut rubber sealing ring will fall to the position directly below it under the action of gravity. The debris generated during the cutting process splashes outward and is blocked by the wall of the protective cover 7, so it can only pass downward through the mesh holes on the surface of the metal mesh plate 801 and fall into the chip collecting box 9 directly below the collecting box 8 for collection, thereby ensuring the personal safety of the operator during the cutting process. After completing the cutting operation of a whole rubber tube 5, the operator can manually pull the collecting box 8 to slide it out from the inside of the protective cover 7 and take out the sealing rubber ring from it. The chip collecting box 9 can perform regular and centralized cleaning of the debris collected inside it.
