Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and more specifically, to a vacuum sealing integrated machine. Background Technology

[0002] In the pharmaceutical industry, liquid medicine flexible packaging products have inner and outer bags. The inner bag contains the liquid medicine, and the outer bag protects the product. Products requiring high-temperature sterilization have strict requirements on the sterilization temperature and time, as well as the material and contact method of the packaging bag. With the requirement to replace PVC packaging materials with non-PVC materials to improve drug quality, the amount of air inside the outer bag affects the sterilization effect. It is necessary to control the air inside the packaging bag to a very small range to ensure the sterilization quality of the product and ensure the qualification of the medicine.

[0003] Existing vacuum packaging and sealing machines often require removing the product-filled packaging bag from the conveyor and correctly placing it onto the production line. Then, the packaging bag is opened, and a negative pressure nozzle for vacuuming is inserted into the bag. Furthermore, the conveyor of the product-filled packaging bag needs to be stopped during the vacuuming process before the vacuuming operation can begin. Therefore, the continuity of the vacuuming operation is low, resulting in low work efficiency. To address this, we propose a new vacuum sealing machine. Summary of the Invention

[0048] In this embodiment, specifically, such as Figure 1-2 As shown in Figure 8, the cutting mechanism 8 is mainly used to cut the top edge of the opening of the packaging bag 10 to prevent the opening of the packaging bag 10 from being pulled during the heat sealing process, which would cause the opening of the packaging bag 10 to be torn. During operation, the fifth cylinder 84 drives the cutting support 82 to move up and down, which in turn drives the blade 83 on the cutting support 82 to move synchronously to achieve the cutting operation.
