When cutting, the movable frame 3 is initially located on one side of the processing table 1, and the material to be cut is laid flat on the rubber pad 20. By loosening the butterfly bolt 12, the position of the slider 10 on the I-shaped crossbeam 7 is slidably adjusted, so that the slider 10 drives the cutting blade 14 to move. The distance is observed by the scale value 9, so as to adjust the spacing of the cutting blade 14 as needed, which is convenient for cutting materials of different sizes. After the position of the cutting blade 14 is adjusted, the butterfly bolt 12 is tightened to fix the position of the cutting blade 14, and then the lifting cylinder 6 is started to make the lifting cylinder 6 push the I-shaped crossbeam 7 to move downward, and the I-shaped crossbeam 7 The cutting blade 14 is driven downward by the slider 10 and the tool holder 13 so that the cutting blade 14 is pressed on the material to be cut. When the cutting blade 14 is pressed down, the initial position of the pressure roller 18 is lower than the cutting blade 14, so the pressure roller 18 is pressed on the material before the cutting blade 14, so that the spring 19 is compressed. The thrust generated by the compression of the spring 19 causes the pressure roller 18 to be pressed on the surface of the material to be cut. Then the staff pulls the movable frame 3 from one side of the processing table 1 to the other side of the processing table 1. During the pulling process, the cutting blade 14 and the pressure roller 18 roll, and the material is cut by the rolling of the cutting blade 14. The material to be cut is flattened by the rolling of the pressure roller 18 to ensure that the material is flat and wrinkle-free, thereby ensuring the neatness of the cutting edge, so that multiple cutting can be completed at one time.
