[0002] In the manufacture of packaging bags, a long-width raw material roll needs to be slitted into several narrow-width raw material belts, and then the raw material belts are formed into packaging bags through bag making and sealing. In this slitting process, if it is performed manually, the efficiency is slow and the slitting quality is poor. Therefore, a slitting machine is commonly used to slit the raw material roll.
[0003] The existing packaging bag slitting machine mostly transports the packaging bag to the lower side of the slitting knife through the conveying belt at this time, and then starts the slitting knife to cut the packaging bag. However, the material of the packaging bag is generally soft, so that when the slitting knife is pressed down, the packaging bag will be wrinkled, which affects the slitting effect of the packaging bag. In addition, the packaging bag cannot be positioned and pressed tightly when it is slitted, so that the packaging bag will be wrinkled, which will cause the packaging bag to be slanted during slitting. Therefore, a packaging bag positionable slitting machine is needed to improve this problem. SUMMARY
