[0024] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0025] Reference Figure 1-6 The embodiment of the utility model is a vacuum packaging mechanism, which includes a bottom plate 1, a lower shell 3 fixedly connected to the top of the bottom plate 1, and an upper shell 2 hinged to the top of the lower shell 3, forming an openable structure, which is convenient for placing and removing the bags to be packaged. A vacuum chamber 6 is provided inside the lower shell 3 to ensure that air can be effectively removed during the vacuuming process. A sealing ring 4 located on the outer ring of the vacuum chamber 6 is embedded in the lower shell 3, and a sealing ring 4 that cooperates with each other is also embedded in the upper shell 2 to ensure that the vacuum chamber 6 does not leak when vacuuming. An exhaust valve 8 and a vent valve 7 are provided inside the vacuum chamber 6. Both the vent valve 7 and the exhaust valve 8 are solenoid valves. The exhaust valve 8 is used to control the vacuuming work, and the vent valve 7 is used to realize the communication between the vacuum chamber 6 and the external air after the sealing is completed, so as to facilitate the inflation of the vacuum chamber 6 and the opening of the upper shell 2.

[0026] Two positioning components are also symmetrically provided inside the vacuum chamber 6. The positioning components include a positioning block 20 fixedly connected to the inner surface of the lower shell 3 and set as an L-shaped structure, a slot 21 opened inside the positioning block 20 and arranged horizontally, and two protrusions 22 spaced apart on the inner side of the slot 21.

[0027] The bag opening is placed within the vacuum chamber 6 and inserted into the slot 21. The raised portion 22 facilitates positioning of the bag opening within the vacuum chamber 6, thereby ensuring better positioning of the bag. This ensures that when the upper shell 2 is closed, the bag opening is pressed between the sealing ring 4 and the bag opening is located within the vacuum chamber 6, achieving vacuum evacuation of the bag. The provided vacuum packaging mechanism has a simple structure and is easy to operate, achieving efficient vacuum evacuation and being convenient to use.

[0028] In order to achieve a detachable connection between the upper shell 2 and the lower shell 3, two snap-fit ​​assemblies are symmetrically provided on the side of the lower shell 3 away from the hinge. The snap-fit ​​assembly includes a first connecting plate 9 fixedly connected to the outside of the upper shell 2, a second connecting plate 13 fixedly connected to the outside of the lower shell 3 and located below the first connecting plate 9, an internal threaded plate 12 rotatably connected to the inner side of the second connecting plate 13, a screw 10 threadedly connected to the inside of the internal threaded plate 12 and a knob 11 fixedly connected to the end of the screw 10. The first connecting plate 9 and the second connecting plate 13 are both U-shaped structures.

[0029] After the upper shell 2 is placed on the lower shell 3, the screw 10 is rotated into the U-shaped groove of the first connecting plate 9, and the knob 11 is located above the first connecting plate 9. Rotating the knob 11 drives the screw 10 to rotate inside the internal threaded plate 12, so that the knob 11 fits against the top of the first connecting plate 9, completing the connection between the upper shell 2 and the lower shell 3, ensuring the tight fit of the sealing ring 4 and the sealing of the vacuum chamber 6.

[0030] Heat sealing plates 5 are embedded inside the upper shell 2 and the lower shell 3 and on the side of the vacuum chamber 6 away from the hinge, for heat sealing the packaging bag after vacuuming, completing the continuous work of vacuuming and sealing.

[0031] An L-shaped mounting bracket 14 is fixedly connected to one side of the top of the base plate 1, an electric push rod 15 is fixedly connected to the bottom of the mounting bracket 14, a movable plate 16 is fixedly connected to the bottom of the piston rod of the electric push rod 15, and a rubber pad 17 is fixedly connected to the bottom of the movable plate 16.

[0032] When the packaging bag is placed on the top of the bottom plate 1 for vacuuming, the electric push rod 15 drives the movable plate 16 and the rubber pad 17 at the bottom to apply pressure to the packaging bag, so as to facilitate the exhaust of gas and improve the vacuuming effect.

[0033] A display screen 18 and a plurality of buttons 19 are provided on the top of the upper shell 2. The display screen 18 is used to display the working status of the vacuum packaging mechanism, and the buttons 19 are used to control its various functions.

[0034] Working principle: The bag opening is placed inside the vacuum chamber 6 and inserted into the slot 21. The raised portion 22 facilitates positioning of the bag opening inside the vacuum chamber 6, thereby better positioning the bag. When the upper shell 2 is closed, the bag opening is pressed between the sealing ring 4 and the bag opening is located inside the vacuum chamber 6, achieving the vacuum operation of the bag.

[0035] After the upper shell 2 is covered on the lower shell 3, the screw 10 is rotated to the inside of the U-shaped groove of the first connecting plate 9, and the knob 11 is located above the first connecting plate 9. Rotating the knob 11 drives the screw 10 to rotate inside the internal threaded plate 12, so that the knob 11 can fit on the top of the first connecting plate 9, completing the connection between the upper shell 2 and the lower shell 3, ensuring the tight fit of the sealing ring 4 and the sealing of the vacuum chamber 6. The provided vacuum packaging mechanism has a simple structure, convenient operation, can achieve efficient vacuuming, and is easy to use.

[0036] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
