[0023] See also Figures 1 to 5 As shown, the utility model provides a food vacuum packaging device, including a base plate 1, a placement plate 2 is provided on the top of the base plate 1, a fixing plate 3 is provided on the top of the base plate 1 on one side of the placement plate 2, sealing components 4 for sealing the packaging bag are provided on both sides of the fixing plate 3, a fixing component 5 for fixing the bag opening of the packaging bag is provided on one side of the fixing plate 3 on the base plate 1, a vacuum pump 6 is provided on one side of the base plate 1, the output end of the vacuum pump 6 is connected to a connecting hose 7, a main pipe 8 is provided at one end of the connecting hose 7, and an intubation tube 9 is provided on one side of the main pipe 8.

[0024] The food to be vacuum-packed is placed in a packaging bag and the packaging bag is placed on a placement plate 2 so that the bag opening of the packaging bag is placed on a fixing plate 3. At this time, a fixing component 5 is used to fix the bag opening of the packaging bag to ensure that it does not move or deform during the vacuuming process. The bag is inserted through an intubation tube 9 and the vacuum pump 6 is started. The vacuum pump 6 extracts the air in the intubation tube 9 through a connecting hose 7 and a main pipe 8, thereby forming a negative pressure environment in the packaging bag. As the air in the packaging bag decreases, the packaging bag gradually shrinks and adheres to the surface of the food, effectively eliminating oxygen and moisture around the food, and preventing the food from oxidizing and deteriorating. When the vacuum degree in the packaging bag reaches a preset value, the vacuum pump 6 stops working. At this time, the sealing component 4 starts working to heat and seal the bag opening of the packaging bag to ensure that the vacuum state is maintained.

[0025] See also Figures 1 to 3 As shown, the fixing assembly 5 includes a movable plate 51, a pad 52, a second threaded rod 53, a turntable 54, a pressure plate 55, a pressure block 56 and a limiting column 57; the movable plate 51 is provided with two sides and is movably arranged on the base plate 1, and the base plate 1 is provided with a driving component for driving the movable plate 51 to move; the pad 52 is arranged on the top of the movable plate 51; the second threaded rod 53 is arranged on the movable plate 51; the turntable 54 is arranged at one end of the second threaded rod 53; the pressure plate 55 is arranged on the second threaded rod 53; the pressure block 56 is arranged at the bottom of the pressure plate 55; the limiting column 57 is arranged on the movable plate 51 on one side of the second threaded rod 53.
