[0002] Packaging machinery refers to machinery that can complete all or part of the packaging process for products and commodities. The packaging process includes major processes such as filling, wrapping and sealing, as well as related pre- and post-processes such as cleaning, stacking and unpacking. In addition, packaging also includes processes such as measuring or stamping on the packaging. Using machinery to package products can improve productivity, reduce labor intensity, meet the needs of large-scale production, and meet the requirements of cleanliness and hygiene.

[0003] Most packaging machines on the market use flat or serrated cutters. Equipment for making irregularly shaped bags usually involves pre-making the bags and then filling them with materials on the machine, which requires purchasing bags separately, resulting in high costs and large investments. At the same time, the equipment cannot meet the needs of bags of various shapes. Therefore, an irregularly shaped bag cutting mechanism is proposed to solve the above problems. Utility Model Content
