[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0033] like Figure 1-Figure 3 As shown, a food packaging device in one embodiment of the present invention includes a cabinet 1 and a nitrogen generator 16. The nitrogen generator 16 is installed on the cabinet 1 and can provide the protective nitrogen required during the packaging process. A limit ring 4 is fixedly installed on the cabinet 1. The limit ring 4 is welded to the surface of the cabinet 1. A support column 3 is fixedly installed inside the limit ring 4. A first round bucket 2 is fixedly installed on the upper end surface of the support column 3. A round tube 8 is installed at the lower end of the support column 3. A packaging bag 9 is sleeved on the outside of the round tube 8. At the same time, the packaging bag 9 is fixed to the bottom of the support column 3, and the packaging bag 9 is sleeved on the outside of the round tube 8.

[0034] A long groove 11 is welded on the top upper surface of the cabinet body 1. The long groove 11 is designed in an "L" shape. An inclined plate 1101 is integrally formed inside the long groove 11. A second round bucket 10 is installed above the long groove 11.

[0035] When performing the packaging operation, food needs to be poured into the second circular bucket 10. After the food falls into the second circular bucket 10, it will slide down through the inclined plate 1101 with a higher slope. At the same time, the adjusting shovel 1102 is fixedly connected to the end of the long groove 11 close to the first circular bucket 2. The food rolls down to the position of the adjusting shovel 1102 through the inclined plate 1101. Therefore, the food can fall into the interior of the first circular bucket 2 and then fall into the circular tube 8. Then, it falls into the packaging bag 9 through the interior of the circular tube 8, and then the food in the packaging bag 9 is sealed by the sealing machine to complete the packaging operation.

[0036] A first air supply pipe 13 and a second air supply pipe 14 are mounted on either side of the support column 3. A gas delivery pipe 15 is fixedly mounted to the output end of the nitrogen generator 16, with one end of each of the first and second air supply pipes 13, 14 connected to one end of the gas delivery pipe 15. The nitrogen generator 16 is welded to the side of the cabinet 1, improving operational safety. Nitrogen generators are conventional technology in the field and are common knowledge, so detailed description is omitted here.

[0037] A boss 301 is integrally formed at the bottom of the support column 3, and a first connecting pipe 5 and a second connecting pipe 6 are fixedly installed at the bottom of the boss 301. One end of the first connecting pipe 5 is connected to the first air supply pipe 13, and one end of the second connecting pipe 6 is connected to the second air supply pipe 14; the first air supply pipe 13 passes through the support column 3 and the boss 301 in sequence to be connected to the first connecting pipe 5, and the second air supply pipe 14 passes through the support column 3 and the boss 301 in sequence to be connected to the second connecting pipe 6. A water valve 12 is fixedly installed on both the first air supply pipe 13 and the second air supply pipe 14.

[0038] The nitrogen in the first air supply pipe 13 is transported to the first connecting pipe 5 through the support column 3 and the boss 301, and the nitrogen in the second air supply pipe 14 is also transported to the second connecting pipe 6 through the support column 3 and the boss 301. Water valves 12 are installed on both the first air supply pipe 13 and the second air supply pipe 14. The nitrogen delivery pressure can be adjusted by turning the knob on the water valve 12, which facilitates the adjustment of the nitrogen pressure in response to different working conditions.

[0039] like Figure 2-Figure 7 As shown, an air supply ring 7 is fixedly installed at the lower end of the first connecting tube 5 and the second connecting tube 6. The outer wall of the air supply ring 7 is in close contact with the inner wall of the circular tube 8. The air supply ring 7 includes a first air supply ring 701 and a second air supply ring 702. The first air supply ring 701 and the second air supply ring 702 are both hollow in design. The first air supply ring 701 is provided with an air supply hole 703 for blowing air upward for buffering, and the second air supply ring 702 is provided with an air supply hole 703 for blowing air into the inside of the circular tube 8.

[0040] The nitrogen transmitted from the first air supply pipe 13 can be transported into the first connecting pipe 5, and the nitrogen transmitted from the second air supply pipe 14 can be transported into the second connecting pipe 6. Then the nitrogen is transmitted to the first air supply ring 701 through the first connecting pipe 5, and is transmitted to the second air supply ring 702 through the second connecting pipe 6. The first air supply ring 701 and the second air supply ring 702 are hollow structures and are separated by a partition plate 706 to ensure that they are not affected by each other and that the gas transported to the first air supply ring 701 and the second air supply ring 702 will not be lost. The sealing is good, thereby ensuring work efficiency.

[0041] The first air supply ring 701 is provided with an air supply hole 703 for blowing air upwards for buffering. The nitrogen delivered through the first connecting tube 5 can be transmitted to the interior of the first air supply ring 701. At the same time, air is blown out through the air supply hole 703 opened upwards to buffer the food falling into the circular tube 8, so as to prevent the food from falling too fast and colliding with each other to become debris, thereby ensuring the quality of the packaged product.

[0042] The second air supply ring 702 is provided with an air supply hole 703 for blowing air downwards. The nitrogen delivered through the second connecting pipe 6 can be transmitted to the interior of the second air supply ring 702, and at the same time, the nitrogen is blown out toward the interior of the circular tube 8 through the air supply hole 703 opened downwards.

[0043] A packing bag 9 is folded and sleeved on the circular tube 8, and nitrogen can be directly delivered to the interior of the packing bag 9. In addition, due to the upward blowing of nitrogen through the air supply hole 703 opened upward, the surrounding air can be removed during the falling process of the food, so that the interior of the circular tube 8 is filled with protective gas, thereby preventing food and a large amount of air from entering the packing bag 9 at the same time.

[0044] By cooperating with the air supply holes 703 opened upward and the air supply holes 703 opened downward, the filling of nitrogen protective gas can be efficiently achieved, and then the sealing operation is completed by the sealing machine. At the same time, the nitrogen blown out from the air supply holes 703 opened downward to the bottom of the packing bag 9 can make the packing bag 9 move downward, realizing the automatic falling of the packing bag 9, reducing manual operation and improving the production efficiency of the equipment.

[0045] At the same time, the opening inclination angles of the multiple groups of air supply holes 703 are different, so that the air supply holes 703 can blow air in different directions on the inclined surfaces of the first air supply ring 701 and the second air supply ring 702, so that nitrogen can be blown out more evenly.

[0046] A circular groove 705 is provided on the outer wall of the partition plate 706, and a stain removal ring 704 matching it is installed on the circular groove 705. The stain removal ring 704 is tightly attached to the inner wall of the circular tube 8, and the outer wall of the air supply ring 7 is also tightly attached to the outer wall of the circular tube 8. At the same time, the circular tube 8 is a hollow circular tube and is installed on the lower end face of the support column 3. At the same time, a boss 301 is integrally formed at the lower end of the support column 3. The boss 301 is interference fit with the circular tube 8, and the inner wall of the circular tube 8 is inserted into the boss 301 and can be freely connected and released. Therefore, when pulling the circular tube 8, because the air supply ring 7 is in a fixed state, the circular tube 8 can be pulled to scrape and clean some food residues on the surface of the circular tube 8 by sliding the circular tube 8 on the surface of the air supply ring 7. At the same time, the stain removal ring 704 on the air supply ring 7 is made of a material with strong oil absorption. Preferably, in this embodiment, the stain removal ring 704 is preferably oil-absorbing cotton, which can quickly remove stains and achieve secondary cleaning, thereby reducing the inconvenience and difficulty of the staff when cleaning the pipeline and improving work efficiency.

[0047] When in use, first pour the food into the interior of the second circular bucket 10, then turn on the start button of the nitrogen generator 16, and at this moment the nitrogen generator 16 starts to work. The food poured into the second circular bucket 10 is transported to the interior of the circular tube 8 through the inclined plate 1101. At the same time, the nitrogen generator 16 converts the air into nitrogen and transports it to the interior of the first air supply pipe 13 and the second air supply pipe 14 through the air pipe 15. Then a part of the nitrogen in the air pipe 15 passes through the first air supply pipe 13 and passes through the support column 3 and the boss 301 to enter the interior of the first connecting pipe 5, and another part of the nitrogen in the air pipe 15 passes through the second air supply pipe 14 and passes through the support column 3 and the boss 301 to enter the interior of the second connecting pipe 6. At this time, the nitrogen entering the first connecting pipe 5 enters the first air supply ring 701 and is blown upwards through the air supply hole 703 opened upwards, which can blow and buffer the food falling from the circular tube 8, reduce the collision force between the food, and improve the packaging quality; Nitrogen enters the second air supply ring 702 and is blown toward the bottom of the packing bag 9 through the air supply hole 703 opened downward. When the food inside the round tube 8 falls into the packing bag 9, the nitrogen protective gas blown out from the air supply hole 703 opened downward can be filled into the packing bag 9, and the air supply hole 703 opened upward blows upward to isolate the air inside the packing bag 9. The cooperation of the air supply hole 703 opened upward and the air supply hole 703 opened downward can efficiently complete the filling of the nitrogen protective gas, and at the same time, the sealing machine performs the sealing operation to complete the packaging of the food.

[0048] When the circular tube 8 needs to be cleaned, the packing bag 9 at the bottom of the support column 3 can be removed, and the circular tube 8 inserted on the protruding column 301 can be pulled, and the smooth outer surface of the air supply ring 7 and the stain removal ring 704 on the air supply ring 7 can be used to complete the secondary cleaning and decontamination of the inner wall of the circular tube 8.

[0049] When it is necessary to adjust the blowing speed of the air supply hole 703 on the air supply ring 7, the blowing speed can be adjusted by turning the adjusting knob on the water valve 12.
