[0002] Vacuum packaging machines are used for vacuum packaging of food. In order to better improve the shelf life of food, some food packages need to be filled with nitrogen after vacuuming. All of this needs to be done in the vacuum chamber of the packaging machine. In order to meet the working requirements of vacuuming and filling with nitrogen, the vacuum chamber is generally divided into an inner cavity and an outer cavity. First, the inner cavity and the outer cavity are vacuumed at the same time, and then the inner cavity is filled with nitrogen, while the outer cavity needs to remain vacuumed. How to efficiently achieve vacuuming and nitrogen filling of the vacuum chamber to ensure the increase in packaging production speed is a technical problem that technicians need to solve urgently.

The rotating disk is connected to the vacuum machine turntable for synchronous rotation. Ten vacuum chambers are installed on the vacuum machine turntable in equal parts. Each vacuum chamber has an inner cavity and an outer cavity. The gas distribution disk and the chassis are fixedly arranged. Ten stations are arranged on the gas distribution disk in equal parts. The ten stations correspond to the ten vacuum chambers. The inner cavity is provided with a No. 1 inner cavity hole and a No. 2 inner cavity hole. The No. 2 inner cavity hole is located at the top of the inner cavity. An outer cavity hole is arranged in the outer cavity.
