[0002] In the pharmaceutical industry, liquid medicine soft packaging products are packaged in inner and outer bags, with the inner bag containing the liquid medicine and the outer bag protecting the product. Products that require high-temperature sterilization have strict requirements on the sterilization temperature and time length of the liquid medicine, and the material and contact form of the packaging bag have strict requirements. In order to improve the quality of drugs, PVC packaging materials are required to be changed to non-PVC materials. The air content in the outer bag packaging affects the sterilization effect. The air in the packaging bag needs to be controlled within a very small range to ensure the sterilization quality of the product and ensure the quality of the drugs.

[0003] The existing vacuum packaging and sealing integrated machine often requires that the packaging bag containing the product be taken away from the conveying mechanism, correctly placed on the production line, and then the packaging bag be opened, and the negative pressure suction nozzle for vacuuming treatment be inserted into the packaging bag for vacuuming treatment; and during the vacuuming process, the conveying of the packaging bag containing the product needs to be stopped before the vacuuming operation is performed, so the vacuuming operation continuity is low and the work efficiency is low.
