[0021] like Figure 1 As shown, a vacuum sealing packaging machine includes a longitudinally arranged belt conveyor 1 and a control terminal device for controlling the operation of the belt conveyor. An inverted U-shaped support frame 3 is fixed on the upper side of the belt conveyor 1 near the middle position. A sealing box 2 is arranged inside the support frame 3, and an electric lifting rod 4 for raising and lowering the sealing box 2 is fixed on the upper side of the support frame 3. A photoelectric sensor 5 is installed on the belt conveyor 1 and is located on the rear side of the support frame 3. When the packaging bag containing food is conveyed by the belt conveyor 1, the photoelectric sensor 5 is triggered when the packaging bag reaches the sealing position. At this time, the belt conveyor 1 stops conveying, and the electric lifting rod 4 drives the sealing box 2 to descend and perform vacuum sealing on the packaging bag.

[0022] like Figure 2 As shown, the sealing box 2 includes two fixed sleeve boxes 22 and a movable sleeve box 25 with opposite openings on the left and right sides. The front and rear sides of the fixed sleeve box 22 are fixed with driving components 21 that drive the movable sleeve box 25 to move left and right. The top rod of the electric lifting rod 4 passes through the top of the support frame 3 and is fixedly connected to the fixed sleeve box 22. The inner sides of the fixed sleeve box 22 and the movable sleeve box 25 are provided with heat sealing components 26. The left and right heat sealing components 26 cooperate with each other to heat seal the packaging bag. The fixed sleeve box 22 is connected to a vacuum pump through a hose. The driving component 21 drives the movable sleeve box 25 to move to the right, thereby opening the entire sealing box 2. At this time, the electric lifting rod 4 drives the sealing box 2 to descend and fit over the upper end of the packaging bag and clamp it. The vacuum pump is used to draw a vacuum into the fixed sleeve box 22, thereby vacuuming the packaging bag. Finally, the packaging bag is heat sealed by the heat sealing components 26.

[0023] like Figure 3 As shown, a guide tube 23 and a guide rod 24 are fixedly fixed on the upper side of the fixed sleeve 22. The guide tube 23 and the guide rod 24 both extend upward through the top of the support frame 3. The guide tube 23 and the guide rod 24 guide the fixed sleeve 22 when it is raised or lowered.

[0024] The upper end of the guide tube 23 is connected to the vacuum pump via a hose, and the vacuum pump evacuates the fixed sleeve 22 through the hose and the guide tube 23.

[0025] likeFigure 3 As shown, sealing strips 27 are fixed to the edges of the opposite opening ends of the fixed sleeve 22 and the movable sleeve 25, and the fixed sleeve 22 and the movable sleeve 25 are sealed when they are joined together by the sealing strips 27.

[0026] The fixed sleeve 22 and the movable sleeve 25 have clamping grooves 28 on their lower edges at the opposite opening ends. When the fixed sleeve 22 and the movable sleeve 25 clamp the packaging bag at the sealing point, the clamping grooves 28 can prevent the packaging bag from being sealed shut, thus preventing vacuuming.

[0027] like Figure 4 As shown, the heat sealing component 26 includes a heating strip 263 disposed within a fixed sleeve 22 or a movable sleeve 25. Multiple movable rods 262 are fixed to one side of the heating strip 263. A connecting plate 264 is fixed to the multiple movable rods 262 through the side wall of the fixed sleeve 22 or the movable sleeve 25. Multiple second electric telescopic rods 261 are fixed to one side of the connecting plate 264. The top rod of the second electric telescopic rod 261 passes through the connecting plate 264 and is fixedly connected to the fixed sleeve 22 or the movable sleeve 25. When sealing the packaging bag, the second electric telescopic rods 261 drive the connecting plate 264 to move the movable rods 262 and the heating strip 263, thereby causing the heating strips 263 on both sides to clamp the sealing area of ​​the packaging bag for heat sealing.

[0028] like Figure 5 As shown, the driving component 21 includes a fixing block 212 fixed on the fixed sleeve box 22 and a connecting block 213 fixed on the movable sleeve box 25. A first electric telescopic rod 211 is fixed on one side of the fixing block 212. The top rod of the first electric telescopic rod 211 passes through the fixing block 212 and is fixedly connected to the connecting block 213. By extending the top rod of the first electric telescopic rod 211, the connecting block 213 is driven to move the movable sleeve box 25 to the right away from the fixed sleeve box 22, thereby opening the sealing box 2 and sealing the sealing end of the packaging bag.

[0029] In this embodiment, the belt conveyor 1 is started to transport the packaging bag containing food. When the packaging bag reaches the sealing position, it will trigger the photoelectric sensor 5. The photoelectric sensor 5 will transmit the photoelectric signal to the control terminal device. At this time, the control terminal device controls the belt conveyor 1 to stop transporting and controls the electric lifting rod 4 to drive the sealing box 2 to descend. After descending to the set height, the control terminal device controls the top rod of the first electric telescopic rod 211 to extend, thereby driving the connecting block 213 to move the movable sleeve 25 to the right away from the fixed sleeve 22, so that the sealing box 2 opens and fits over the sealing end of the packaging bag and then closes to clamp the upper end of the packaging bag. At this time, the second electric telescopic rod 261 is controlled to drive the connecting plate 264 to move the movable rod 262 and the heating strip 263, so that the heating strips 263 on both sides clamp the sealing end of the packaging bag for heat sealing treatment.

[0030] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
