[0034] Working principle: When using the vacuum packaging machine, manually put the food inside the packaging bag, place the packaging bag inside the vacuum chamber 3, so that the opening of the packaging bag is set on the top of the heating block 6, and then cover the top of the vacuum chamber 3 of the packaging bag with the connecting cover 5, so that the air inside the packaging bag can be well evacuated, so that the food can be well vacuum packaged. Because there are two vacuum chambers 3 on the top of the packaging machine, when the vacuum chamber 3 on one side is working, the operator can place the packaging bag containing food inside the vacuum chamber 3 on the other side in advance, so that the vacuum packaging becomes efficient. When using the adjustment device 8, first manually control the rotating circular plate 805 Rotation, by manually controlling the rotation of the rotating circular plate 805, the threaded rod 804 can be well controlled to rotate inside the sliding groove 801, because the thread direction on the surface of the threaded rod 804 is opposite from the middle to both sides, and thus the sliding block 802 can be well controlled to approach or move away from the inner wall of the vacuum chamber 3 at the same time, so that the sliding block 802 drives the limiting bar 803 to approach or move away from the inner wall of the vacuum chamber 3, so that the limiting bar 803 can be slid to the appropriate position inside the vacuum chamber 3 according to the different sizes of packaging bags, and then the side with the packaging bag can be set on the side of the limiting bar 803, so that the same position of the bag mouth farthest from the packaging bag can be set above the heating block 6. Manually slide the rubber block 808 into the interior of the fixing groove 809, and then squeeze the rubber block 808 into the interior of the positioning groove 810, so that the sliding block 802 and the limiting strip 803 can be well connected together. The limiting strip 803 and the sliding block 802 can be separated by reverse operation, so as to avoid affecting the vacuum packaging machine for vacuum packaging of large foods. When the limiting device 9 is used, when the connecting cover 5 is covered to the top of the vacuum chamber 3, that is, when the rectangular plate 904 moves downward, the rectangular plate 904 squeezes the top of the U-shaped plate 902. When plate 904 squeezes the top of the U-shaped plate 902, it drives the roller 909 to rotate on the surface of the round rod 908, so that the rectangular plate 904 can squeeze the U-shaped plate 902 to slide on the inner wall of the connecting groove 901, so that the spring 906 is stretched. When the connecting cover 5 completely covers the top of the vacuum chamber 3, the spring 906 returns to its original state, and then pulls the U-shaped plate 902 to slide on the inner wall of the connecting groove 901, so that the rectangular plate 904 slides into the inside of the U-shaped plate 902, thereby well restricting the connecting cover 5 to the top of the vacuum chamber 3.
