[0001] The utility model relates to the technical field of tea packaging, in particular to a vacuum packaging machine for tea anti-oxidation. Background Art

[0002] As a popular beverage, the quality and taste of tea depend largely on the way it is packaged and stored. Traditional tea packaging mostly uses paper bags, iron boxes, etc. Although they can isolate the outside air to a certain extent, it is still difficult to avoid the oxidation of tea leaves during long-term storage.

[0003] Among them, announcement number CN220448246U discloses a tea vacuum packaging machine, including a packaging box, a material discharge plate is fixedly installed on one side of the packaging box, a packaging groove is opened on one side of the packaging box, a packaging mechanism is arranged inside the packaging box, and the packaging mechanism includes a heating rod, a fixed head, an electric hydraulic rod and a square groove, a square groove is opened on the inner wall of the packaging box, a fixed head is slidably connected to the inner wall of the square groove, a heating rod is fixedly installed on one side of the fixed head, the heating rod is used to seal the packaged tea bags, an electric hydraulic rod is fixedly installed on one side of the inner wall of the square groove, the output shaft of the electric hydraulic rod is fixedly connected to the fixed head, two supporting columns are fixedly installed on one side of the inner wall of the packaging box, and wind boxes are fixedly installed on the top of the two supporting columns. By starting the electric hydraulic rod, the fixed head can be moved in the square groove, and then the heating rod is driven to move downward, so as to perform thermoplastic packaging effect on the packaging bag.

[0033] Among them, the packaging bag is placed on the surface of the storage plate 2, and the open end of the packaging bag is overlapped on the surface of the abutment plate 21. At this time, the telescopic rod in the first cylinder 11 pushes the suction pipe 13 to the inside of the packaging bag through the push plate 12, and at the same time, the telescopic rod in the second cylinder 32 pushes the pressing plate 36 downward to press and seal the opening of the packaging bag to prevent external air from entering the interior of the packaging bag during the suction process and to prevent the tea leaves inside from scattering. At this time, the internal air of the packaging bag is sucked through the suction holes 18 on the surface of the suction pipe 13.

[0034] See also Figure 3 The first cylinder 11 is fixedly installed inside the equipment box 1, the telescopic rod in the first cylinder 11 is fixedly connected to the push plate 12, and the positions inside the equipment box 1 located on the front and rear sides of the first cylinder 11 are fixedly connected to the limit rods 17, and the surfaces of the two groups of limit rods 17 are slidably connected to the limit plates 16, and the two groups of limit plates 16 are respectively fixedly connected to the front and rear ends of the push plate 12. Two groups of suction pipes 13 are provided, and the two groups of suction pipes 13 are respectively fixedly connected to the front and rear ends of the push plate 12, and the left ends of the two groups of suction pipes 13 are fixedly connected to the connecting tube 14, and the right end of the connecting pipe 15 is fixedly connected to the connecting tube 14, and the left end of the connecting pipe 15 is connected to the vacuum suction machine.

[0035] Specifically, after the open end of the packaging bag is overlapped on the surface of the abutment plate 21, the telescopic rod in the first cylinder 11 pushes the push plate 12 to the right. At this time, the push plate 12 pushes the suction pipe 13 to the right, and the suction pipe 13 is inserted into the interior of the packaging bag. At the same time, the limit plate 16 slides to the right on the surface of the limit rod 17 to limit the position of the suction pipe 13.

[0036] See also Figure 4 and Figure 5 The second cylinder 32 is fixedly mounted on the upper surface of the support plate 31, the telescopic rod of the second cylinder 32 penetrates the support plate 31 and is fixedly connected to the mounting plate 34, the pressing plate 36 is fixedly connected to the right position of the lower surface of the mounting plate 34, and two groups of card slots 37 are opened on the lower surface of the pressing plate 36, a fixing plate 39 is arranged on the left side of the pressing plate 36, a heating strip 310 is fixedly connected to the lower surface of the fixing plate 39, and two groups of limiting columns 38 are fixedly connected to the upper surface of the fixing plate 39, and the limiting columns 38 are slidably connected to the mounting plate 34, and a supporting spring 311 is sleeved on the surface of the limiting column 38, the upper end of the supporting spring 311 is fixedly connected to the lower surface of the mounting plate 34, and the lower end of the supporting spring 311 is fixedly connected to the upper surface of the fixing plate 39, and two groups of limiting grooves 33 are opened on the surfaces of the two groups of support columns 3, and two groups of limiting blocks 35 are fixedly connected to the front and rear ends of the mounting plate 34, and the limiting blocks 35 are slidably connected to the limiting grooves 33.

[0037] In addition, after the suction pipe 13 is inserted into the packaging bag, the telescopic rod in the second cylinder 32 pushes the mounting plate 34 downward, and then pushes the pressing plate 36 and the fixing plate 39 downward, so that the suction pipe 13 is clamped inside the card slot 37, so that the fixing plate 39 presses and seals the opening of the packaging bag. At this time, the fixing plate 39 is pressed on the upper side of the suction pipe 13. Next, the vacuum suction machine is started to suck the air inside the packaging bag through the connecting pipe 15 and the suction pipe 13. After the suction is completed, the telescopic rod in the first cylinder 11 draws the suction pipe 13 to the left. When the suction pipe 13 is completely pulled out of the packaging bag, the supporting spring 311 immediately pushes the fixing plate 39 downward, so that the fixing plate 39 presses the sealing part of the packaging bag, and performs hot-melt sealing on the sealing part of the packaging bag through the heating strip 310.

[0038] The working principle of the utility model is as follows: the telescopic rod in the first cylinder 11 pushes the suction pipe 13 into the interior of the packaging bag through the push plate 12, and at the same time the telescopic rod in the second cylinder 32 pushes the pressing plate 36 downward to compress and seal the opening of the packaging bag, effectively preventing the tea leaves from scattering, and at the same time, the suction pipe 13 is inserted into the interior of the packaging bag for suction, effectively increasing the speed of sucking the air inside the packaging bag.
