After being pressed, the support plate 16 rotates in the middle of the hinged seat 15, and the two opposing pressure rollers 17 pull the mesh cloth to both sides, so that the mesh cloth is in a taut state, and then the pressure plate 19 contacts and presses the mesh cloth, and the movable knife holder 11 is controlled to move downward to cut the mesh cloth. The waste generated during the cutting process enters the middle of the groove 20. When the pressure roller 17 pulls the mesh cloth, the fixed plate 14 continues to move downward, so that the magic adhesive 21 contacts and contacts the mesh cloth and applies a certain pressure to the mesh cloth to fix the position of the mesh cloth. When the mesh cloth is cutting, the fan 32 is powered on and turned on, and the negative pressure airflow generated inside the fan 32 is blown through the blowing pipe 31. The end of the air duct 31 sucks the mesh cloth through the through hole 34, and sucks the waste from the middle of the groove 20 into the collecting net 33. When the mesh cloth is cut, the fan 32 is controlled to generate air flow inside and discharge it into the blowing pipe 31. When the waste is sucked into the collecting net 33, it slides into the collecting net 33 through the surface of the baffle 4. When blowing, the waste is blocked in the collecting net 33 by the two baffles 4. When the movable knife holder 11 moves downward for cutting, it first contacts the mesh cloth through the support block 52, and elastically contracts through the second spring 51 when under pressure. When the movable knife holder 11 cuts the mesh cloth and moves upward, the second spring 51 is elastically stretched at the same time, and contacts the surface of the movable knife holder 11 through the end of the soft brush 54, and cleans the surface of the movable knife holder 11. When the support block 52 moves downward, the support block 52 is contacted with the mesh cloth through the elastic pad 6.
