On the other hand, by blowing air downward toward the position where the bag has just been opened, the edges of the two parts divided by the laser cutting are bent downward and separated to increase the opening area, thereby further effectively preventing the high-temperature particles from adhering.

[0017] 2. In the present invention, the outer walls of the bottom ends of the cutting sleeve, the air blowing head and the dust collecting head are arranged flush with the top outer wall of the upper plate, so that a gap is left between the bottom ends of the cutting sleeve, the air blowing head and the dust collecting head and the surface of the bag body, so that the dust collecting head can be used to absorb particles before cutting to facilitate the cutting operation.

[0018] 3. In the present invention, when the smoothing block and the vacuum head move close to the pressing block, the lower pressing pieces at both ends are used to pull and smooth the edges of the to-be-cut position outward, and cooperate with the smoothing block moving toward the side to improve the flattening effect of the to-be-cut position. When the cutting sleeve approaches for cutting operation, and the blowing head approaches after cutting is completed, the friction between the lower pressing piece and the surface of the bag body is used to pull the opening after cutting outward to increase, thereby effectively avoiding the high-temperature particles generated from sticking again and affecting the bag opening operation effect.
