[0002] Vacuum packaging machines are devices that create a vacuum environment by extracting and sealing the air inside the packaging. They can inhibit the growth of microorganisms, delay the oxidation and spoilage of food, extend its shelf life, and also compress its volume to save storage space. They are widely used in food, medicine, electronics and other fields. According to their structure, they are divided into single-chamber, double-chamber and rolling types, and are important equipment for preservation and protection in modern packaging.

[0003] Vacuum packaging machines have a wide range of applications. In the food industry, they are used to preserve meat, fruits and vegetables, and cooked food, extending their shelf life. In the pharmaceutical industry, they are used to package medicines to prevent contamination and moisture. They can also be used to package electronic components to prevent moisture and dust. Furthermore, they are suitable for chemical raw materials and precision instruments, achieving the effects of corrosion prevention, oxidation prevention, and saving storage space by isolating them from air.

[0004] Existing vacuum packaging machines have the following problems: smooth bags have a smooth surface and strong sealing properties, and the two sides of the bag opening tend to seal tightly during vacuuming, preventing air from being discharged smoothly. To address these issues, a vacuum packaging machine for smooth bags is proposed. Utility Model Content

When the machine is vacuuming, the air-cutting nozzle is pushed out with the rack. The gaps on the air-cutting nozzle can provide texture for the smooth bag, allowing air to be discharged smoothly. When the machine is sealing, the air-cutting nozzle retracts with the rack and exits into the bag without affecting the sealing of the bag.

[0024] 2. The vacuum packaging machine for smooth bags provided by this utility model achieves forward or reverse rotation through a geared motor. When the geared motor rotates, it drives the rack in contact with it to move back and forth. The rack has a limit rib. When the rack moves to a certain extent, its limit rib touches the position sensor, and the geared motor will stop running. Attached Figure Description
