A collecting frame 11 is provided on the bottom side of the lifting frame 12, and cooling boxes 19 are mounted on both sides of the collecting frame 11. An output roller 15 is provided on the other side of the device body 1, with a movable frame 14 mounted on the upper side of the output roller 15. The input roller 2 and output roller 15 are respectively mounted on both ends of the device body 1 to move the material. Limiting plates 7 are movably connected to both ends of the input roller 2, and multiple positioning holes 6 are arranged on both ends of the input roller 2. The limiting plates 7 are screwed into the positioning holes 6 to limit the conveying of materials of different widths, reducing material deviation. The input roller 2 is an electrically controlled rotating roller, and the output roller 15 has the same structure as the input roller 2.

[0025] Specifically, two adjusting shells 4 are symmetrically installed on the main body 1 of the device. Each adjusting shell 4 is provided with a threaded rotating rod. An adjusting block is threadedly connected to the outside of the threaded rotating rod. The two ends of the limiting rod 3 are rotatably connected between the two adjusting blocks. Multiple pressure plates 5 are provided and arranged on the outer surface of the limiting rod 3. The pressure plates 5 are rubber plates.

[0026] Furthermore, there are two symmetrical support frames 8, and a first motor 9 is installed on the top of each of the two support frames 8. A lead screw is installed on the output end of each first motor 9. The two ends of the lifting frame 12 are respectively threaded to the lead screws on both sides. A heating wire 18 is installed on the bottom surface of the lifting frame 12.

[0027] Furthermore, the device body 1 is provided with a cutting groove to facilitate the complete cutting of the material by the heating wire 18 and avoid the situation where the material is not cut to the bottom. Cooling boxes 19 are provided on the inner walls on both sides of the cutting groove to cool the area around the heating wire 18 during cutting. A gap is left between the two cooling boxes 19, and the collection rack 11 is placed in the cooling box 19 and the gap. The screws at both ends of the collection rack 11 are installed on the device body 1 for easy disassembly and cleaning.

[0028] In this embodiment, a cooler 17 is installed on the bottom side of the device body 1. A circulation pump is installed inside the cooler 17. Cooling pipes 10 are connected between both sides of the cooler 17 and both ends of the cooling box 19 to achieve the effect of circulating cooling. Cooling liquid flows inside the cooling box 19.

[0029] An adjustment groove is provided on the top surface of the tail end of the device body 1. The two ends of the movable frame 14 are connected to the movable frame 14. Two first cylinders 13 are also installed on the tail end of the device body 1. The telescopic ends of the first cylinders 13 are connected to the two ends of the movable frame 14 and act to adjust the cutting length.

[0030] Working principle: When cutting is required, adjust the limiting plate 7 to a position that matches the width of the material, and then put the material in from the input roller 2. The input roller 2 will continuously convey the material forward, and the pressure plate 5 will continuously press the material firmly onto the device body 1. As the material continues to move forward, when it reaches the bottom side of the movable frame 14, the material will squeeze the contact block 21 upward. When it contacts the contact head 20, the controller 16 will control the first motor 9 to move downward, and at the same time control the input roller 2 to stop. During the descent of the lifting frame 12, the heating wire 18 will cut the material until the heating wire 18 moves into the cutting groove. During this process, impurities generated during cutting will fall into the collection rack 11. The cooling box 19 will continuously reduce the temperature around the collection rack 11. After cutting is completed, the lifting frame 12 will return to its original position, and the output roller 15 will be controlled to rotate to remove the cut material. When it is removed, the contact block 21 will reset, and the input roller 2 will be controlled to rotate again. The above operation can be repeated.
