[0023] The following is a further description of the implementation of the present invention and its beneficial effects through specific examples, which shall not be construed as limiting the scope of implementation of the present invention.

[0024] like Figures 1 to 6 As shown, a food vacuum packaging machine includes an exhaust module 1 and a sealing module 3, and the vacuum packaging machine also includes a clamping panel 5, an upper clamping module 2 and a lower clamping module 3; the vacuum packaging machine is provided with an exhaust module 1, an upper clamping module 2, a sealing module 3, a lower clamping module 4 and a clamping panel 5 in sequence from top to bottom; the clamping panel 5 includes a left panel 51, a right panel 52, a panel cylinder 53 corresponding to the left panel 51 and the right panel 52, and a panel support frame 54; the upper clamping module 2 includes an upper fixed rail 21; the lower clamping module 4 includes a lower slide rail 41, a lower support frame 42 and a bottom support frame 43.

There is no need to arrange structures such as a conveyor belt, so the application occupies a small area and has a low maintenance cost.

[0026] The vacuum module 1 includes a vacuum cylinder 11 and a vacuum port 12, and a vacuum cylinder fixing plate 13 and a vacuum port fixing plate 14 arranged in parallel; the vacuum cylinder fixing plate 13 and the vacuum port fixing plate 14 are arranged in parallel, the vacuum cylinder 11 is fixed on the vacuum cylinder fixing plate 13, the vacuum port fixing plate 14 is fixed to the end of the vacuum cylinder 11, the vacuum port fixing plate 14 is provided with a movable positioning rod 15, and the vacuum cylinder fixing plate 13 is provided with a through hole corresponding to the movable positioning rod 15.

[0027] Through the telescopic movement of the vacuum cylinder 11, the relative positions of the vacuum cylinder fixing plate 13 and the vacuum port fixing plate 14 are changed, and the vacuum port 12 is driven to move up and down, so that the vacuum port 12 can evacuate the vacuum packaging bag. In order to prevent the vacuum port 12 from shifting in position during the up and down movement, the present application also provides a movable positioning rod 15 to enhance the stability of the up and down movement.

[0028] The cross-section of the upper fixed rail 21 is set to be a trapezoidal shape with a narrow upper part and a wide lower part, so as to facilitate the threaded assembly of the movable clamping group 2 24, so that the movable clamping group 2 24 is not easy to fall off from the upper fixed rail 21 during operation; the upper fixed rail 21 includes an upper left fixed rail and an upper right fixed rail, and the upper fixed rail 21 is threadedly fixed with a telescopic cylinder 1 22, a movable clamping group 1 23, a movable clamping group 24, a movable clamping group 3 25 and a telescopic cylinder 2 26 in sequence, the telescopic cylinder 1 22 and the telescopic cylinder 2 26 are symmetrical in structure, and the movable clamping group 1 23 and the movable clamping group 3 25 have the same structure.

[0029] The present application adjusts the distance between the two upper fixed rails 21 by setting the telescopic cylinder 1 22 and the telescopic cylinder 2 26 at the two ends of the upper fixed rail 21, so that the movable clamping group 1 23, the movable clamping group 24, and the movable clamping group 3 25 can achieve the clamping effect on the vacuum packaging bag.

A bottom slide rail is provided on the bottom support frame 43. One end of the lower support frame 42 is threadedly fixed to the bottom of the lower slide rail 41, and the other end is movably matched with the bottom slide rail.

[0034] The cross-section of the lower fixed rail 44 is set to be a trapezoid that is wider at the top and narrower at the bottom. The movable clamping group four 46, the movable clamping group five 47, and the movable clamping group six 48 are all threadedly fixed on the top surface of the lower fixed rail 44, so as to facilitate the adjustment of the positions of the movable clamping group four 46, the movable clamping group five 47, and the movable clamping group six 48; a fixing seat 451 corresponding to the feeding clamping group 45 is threadedly fixed on the top surface of the lower fixed rail 44, and the feeding clamping group 45 is threadedly fixed on the side of the fixing seat 451; a relatively positioned air suction bag opening module 461 is also provided in the middle of the movable clamping group four 46, and the vacuum packaging bag is opened by the air suction bag opening module 461.

[0036] Preferably, a loading component corresponding to the loading clamping group 45 can be set, so that the vacuum packaging bags can reach the positions of the corresponding loading clamping groups 45 in sequence; preferably, a feeding component is set above the movable clamping group 24, so that the material falls into the vacuum packaging bag from above the movable clamping group 24; the structures such as the vacuum module 1 and the suction bag opening module 461 designed in this application all need to be provided with corresponding vacuum components. In order to highlight the protection structure of this application, this application omits the description of the above-mentioned components and gives sufficient combination prompts. Personnel in this technical field can combine with the above-mentioned components based on the structure described in this application.

[0037] For the convenience of description, in the following steps, the clamping of the vacuum packaging bag by the movable clamping group 1 23, the movable clamping group 24, and the movable clamping group 3 25 is achieved by the telescopic cylinder 1 22 and the telescopic cylinder 2 26; the clamping of the vacuum packaging bag by the feeding clamping group 45, the movable clamping group 46, the movable clamping group 5 47, the sealing module 3 and the movable clamping group 6 48 is achieved by the telescopic cylinder 4 50, which will not be repeated.

[0038] In the present application, the telescopic cylinder 3 49 drives the vacuum packaging bag clamped in the lower clamping module 4 to the next clamping position, the upper clamping module 2 clamps the vacuum packaging bag, the lower clamping module 4 is reset, and the vacuum packaging bag is clamped to the next clamping position again, thereby reciprocating, so that the vacuum packaging bag completes the vacuuming and sealing steps on the upper clamping module 2 and the lower clamping module 3 without the need for a conveyor belt.

[0039] The application workflow is as follows:

[0040] Step (1): After the feeding clamping group 45 clamps the vacuum packaging bag, the telescopic cylinder three 49 telescopes the vacuum packaging bag to the corresponding position of the movable clamping group one 23, so that the movable clamping group one 23 clamps the vacuum packaging bag, and the feeding clamping group 45 releases the vacuum packaging bag and resets it through the telescopic cylinder three 49.

[0041] Step (2): While the movable clamping group four 46 clamps the vacuum packaging bag, the vacuum packaging bag is opened by the vacuum bag opening module 461, the movable clamping group one 23 is released, and the telescopic cylinder three 49 telescopes the opened vacuum packaging bag to the corresponding position of the movable clamping group two 24. The movable clamping group two 24 clamps the vacuum packaging bag, and the packaging material falls from the top of the movable clamping group two 24 into the opened vacuum packaging bag. The movable clamping group four 46 is reset by the telescopic cylinder three 49.

[0042] Step (3): After the movable clamping group 5 47 clamps the vacuum packaging bag, the movable clamping group 2 24 releases the vacuum packaging bag, and the telescopic cylinder 3 49 telescopes the vacuum packaging bag to be sealed to the corresponding position of the movable clamping group 3 25. After the movable clamping group 3 25 clamps the vacuum packaging bag, the telescopic cylinder 3 49 resets the movable clamping group 5 47 to make the sealing module 3 correspond to the vacuum packaging bag.

[0043] Step (4): The vacuum module 1 is fixedly arranged above the movable clamping group three 25, and the distance between the vacuum cylinder fixing plate 13 and the vacuum port fixing plate 14 is adjusted by telescopic vacuum cylinder 11, so that the vacuum port 12 fixed on the vacuum port fixing plate 14 moves up and down, and the vacuum port 12 is extended into the vacuum packaging bag to extract air; after the vacuuming is completed, the vacuum packaging bag is sealed by the sealing clamp 33; the movable clamping group three 25 releases the vacuum packaging bag, and the sealing module 3 keeps the vacuum packaging bag in a sealing clamping state, and moves to the designated discharge position by the telescopic cylinder three 49, and releases the sealing module 3 to allow the vacuum packaging bag to fall to the designated position.

[0044] In actual use, the vacuum packaging bag needs to go through steps (1) to (4) to complete the steps of loading, vacuuming, sealing, etc., and the steps (1) to (4) can be carried out simultaneously for the vacuum packaging bags arranged in sequence, so that the overall structure is compact and the packaging efficiency is high.

[0045] The above implementation modes cannot limit the protection scope of the present invention. The equivalent modifications and changes made by those skilled in the art without departing from the overall concept of the present invention are still within the scope of the present invention.
