[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 In this embodiment, a vacuum packaging machine with a sealing structure includes a packaging mechanism, a sealing mechanism is arranged inside the packaging mechanism, a plurality of supporting mechanisms are arranged inside the packaging mechanism, and a supporting plate 17 is placed on the top of the entire supporting mechanism.

[0021] In this embodiment, the sealing mechanism includes an upper heating assembly 6, a connecting rod 7, an adjusting cylinder 9 and a lower sealing seat 12. The number of upper heating assemblies 6 is two, and the upper heating assembly 6 is fixedly installed inside the packaging mechanism. The number of lower sealing seats 12 is four, and the lower sealing seats 12 are evenly fixedly installed on the left and right sides of the interior of the packaging mechanism. The outside of the lower sealing seat 12 is hinged with a U-shaped pressure rod 14, and the top of the lower sealing seat 12 is fixedly installed with a lower heating block 13. The adjusting cylinder 9 is fixedly installed inside the packaging mechanism, and the output end of the adjusting cylinder 9 is fixedly installed with an adjusting Rod 10, the limit block 18 is fixedly installed inside the packaging mechanism, the adjusting rod 10 is slidably installed inside the limit block 18, T-shaped adjusting blocks 11 are fixedly installed on the left and right ends of the front side of the adjusting rod 10, there are two connecting rods 7, the connecting rod 7 is fixedly installed inside the packaging mechanism, a compensation hole 8 is opened on the front side of the connecting rod 7, the T-shaped adjusting block 11 is located inside the compensation hole 8, the front lower sealing seat 12 is relatively inclined to the rear lower sealing seat 12, the front and rear upper heating assemblies 6 are inclined opposite to each other, and the upper heating assembly 6 and the lower sealing seat 12 are inclined at the same angle.

[0022] It should be noted that the upper heating assembly 6 includes an upper sealing seat, an upper heating block, a slide block, and an automatic airbag, wherein the upper heating block, the slide block and the automatic airbag constitute a pressure regulating device. After the packaging mechanism is vacuumed to a preset value, the automatic airbag is activated to allow the upper heating block to extend through the limit of the slide block, and cooperate with the lower heating block 13 to achieve rapid heating and sealing of the packaging bag mouth.

[0023] Specifically, first adjust the supporting mechanism to the corresponding position, then place the packaging bag filled with liquid inside the packaging mechanism, and make the packaging bag mouth be clamped on the lower heating block 13 of the lower sealing seat 12 by the U-shaped pressure rod 14. At this time, start the packaging mechanism to drive the upper heating assembly 6 to move to the top of the two lower sealing seats 12 on the left, and slowly descend to approach the lower heating block 13. During the contact process, the packaging mechanism starts vacuuming, and then the upper heating assembly 6 and the lower heating block 13 contact the packaging bag mouth. When the vacuum degree reaches the preset value, the internal heating block of the upper heating assembly 6 is adjusted by the pressure regulating device, so that the upper heating assembly 6 and the lower heating block 13 are heated and the packaging bag mouth is clamped and heated, so that the packaging bag mouth is quickly sealed. Since the upper heating assembly 6 and the lower sealing seat 12 are inclined, the liquid contained in the packaging bag is prevented from being squeezed and leaked.

[0024] In this embodiment, the packaging mechanism includes a vacuum packaging machine body 1, and two vacuum chambers 2 are arranged on the top of the vacuum packaging machine body 1. The left and right ends of the front side of the vacuum packaging machine body 1 bracket are rotatably installed with a rotating shaft 3 with one end penetrating and extending to the rear side of the vacuum packaging machine body 1. Two transmission rods 4 are fixedly installed on the outside of the rotating shaft 3. The back side of the front transmission rod 4 is rotatably installed with a sealing cover 5 with one end rotatably connected to the front side of the rear transmission rod 4 as a whole. The upper heating assembly 6 is fixedly installed inside the sealing cover 5. Four lower sealing seats 12 are evenly fixedly installed on the front and rear sides of the inner walls of the left and right vacuum chambers 2, and the lower sealing seat 12 is located at the upper end of the inner wall of the vacuum chamber 2.

[0025] Specifically, starting the regulating cylinder 9 drives the regulating rod 10 to move the inside of the limit block 18 to the left or right, so that the T-shaped regulating block 11 moves inside the compensation hole 8, so that the connecting rod 7 drives the rotating shaft 3 to rotate left or right at a fixed point, so that the rotating shaft 3 drives the transmission rod 4 to rotate left or right. Since the sealing cover 5 is rotatably connected with the transmission rod 4, the sealing cover 5 maintains a parallel state with the top of the vacuum packaging machine body 1 due to its own weight, thereby driving the sealing cover 5 to achieve a sealed state for the left and right sealing chambers. When the sealing cover 5 moves to the outside of the left vacuum chamber 2, the packaging bag can be installed in advance inside the other vacuum chamber 2, thereby improving the sealing efficiency of the bag mouth.

[0026] In this embodiment, the bearing mechanism includes a U-shaped limit seat 15, the number of which is four, and the U-shaped limit seats 15 are evenly fixedly installed on the left and right sides of the inner wall of the vacuum chamber 2. A U-shaped support rod 16 with one end rotatably connected to the rear U-shaped limit seat 15 is installed inside the front U-shaped limit seat 15. The front and back sides of the U-shaped support rod 16 and the inner wall of the U-shaped limit seat 15 are provided with resistance-increasing patterns. The bearing plate 17 is placed on the top of the left and right U-shaped support rods 16 as a whole. The adjusting cylinder 9 and the limit block 18 are fixedly installed inside the bracket of the vacuum packaging machine body 1, and the two connecting rods 7 are fixedly installed on the outside of the left and right rotating shafts 3 respectively.

[0027] Specifically, since the front and back sides of the U-shaped support rod 16 and the inner wall of the U-shaped limit seat 15 are provided with resistance-increasing patterns, the U-shaped support rod 16 can be stored by rotating it upward with the rotation point of the U-shaped limit seat 15 as the center, thereby avoiding affecting the use of the supporting plate 17; when packaging bags of different heights are to be sealed, the U-shaped support rod 16 of the corresponding height can be moved downward with the rotation point of the U-shaped limit seat 15 as the center, so that the inner bottom wall of the U-shaped limit seat 15 limits the movement of the U-shaped support rod 16 to make it flat, and then the supporting plate 17 is placed on the top of the left and right U-shaped support rods 16 as a whole, thereby realizing the sealing processing of different packaging bags.
