The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.

[0033] Embodiment: During operation, the spacing of the guide plates 21 is adjusted according to the width of the packaging bag, and the rotating shaft 17 is rotated to make the pair of main gears 22 drive the pair of secondary gears 23 to rotate, thereby making the pair of wire drawing rods 19 rotate, and the pair of sliders 20 screwed thereon move relatively in the slide groove 18, thereby making the pair of guide plates 21 move relatively. By adjusting the spacing of the guide plates 21 to adapt to the width of the packaging bag, the packaging bag can be guided. After the adjustment is completed, the packaging bag is passed through the guide plates 21 on both sides in turn to make it flat. It is placed vertically on the workbench 1, and the motor 15 drives the screw 12 to rotate, so that the slide 14 screwed thereon drives the slide 2 to move horizontally along the slide rail 13, and the cutter 6 moves to above the cutting position of the packaging bag. The electric push rod 3 drives the cross plate 5 to descend, so that the cutter 6 cuts the packaging bag. Before the cutter 6 contacts the packaging bag, the pressure plates 7 on both sides are first pressed against the packaging bag. As the cross plate 5 descends, the spring 10 is gradually compressed, and the pressure plate 7 presses and fixes the packaging bag, and then the cutter 6 completes the cutting work to ensure the cutting accuracy.
