Subsequently, the collar 14 rotates, and the rotation of the collar 14 drives the positioning ring 15 to rotate. The rotation of the positioning ring 15 can move the ejector rod 12 and the spreader outwards. When the positioning ring 15 moves outwards, it can fix the inner wall of the plastic packaging bag roll and prevent the plastic packaging bag roll from loosening on the sleeve 7. After the plastic packaging bag roll is fixed by multiple support plates 10, the gear two 17 and the toothed belt drive the gear one 16 and the rotating ring 9 to rotate. The rotating ring 9 can drive the sleeve 7 to rotate, and the rotation of the sleeve 7 can drive the plastic packaging bag roll thereon to rotate. When the rotation speed of the plastic packaging bag roll is stable, the cutting machine 2 is adjusted to an appropriate position through the moving seat 4 and the slide rail 3, and the plastic packaging bag roll is cut. After the cutting of the plastic packaging bag roll at the edge is completed, the cutting machine 2 is moved again to slit the plastic packaging bag roll. After slitting is completed, the support plate 18 is lowered, and the slit plastic packaging bag roll can be removed.
