[0002] In the field of packaging equipment, ton bag packaging machines are currently widely used in the packaging field. When packaging finer powders, air will be mixed in the materials during the packaging process, making the bags unstable and prone to tilting, making them unable to be transported to the next process. In order to discharge the air mixed in the materials in the bags, the machines often wait in place for the air mixed in the materials in the bags to be slowly discharged, which seriously affects the packaging speed.
