Description

Technical Field

[0001] The utility model relates to the technical field of food packaging, in particular to a vacuum bag packaging sealing device. Background Art

[0002] Vacuum bag packaging is a common food packaging method. It creates a vacuum environment by placing the food in a special plastic bag and extracting the air from the bag using a vacuum pump or vacuum packaging machine, and then uses a sealing device to seal the bag.

[0003] After searching, the utility model with the publication number of "CN217171070U" provides "a vacuum bag product sealing device, including a body, a telescopic guide rod is fixedly installed on the upper surface of the body, a sealing cover plate is fixedly connected to the upper surface of the telescopic guide rod, a first electric push rod is fixedly installed on the inner top wall of the sealing cover plate, a hot melt block is provided at the power output end of the first electric push rod, second electric push rods are installed on the two side surfaces of the body, the power output end of the second electric push rod is fixedly connected to the sealing cover plate, and an air pump is fixedly installed on the side of the body. The beneficial effect of the utility model is that the height of the placement plate can be adjusted by the height adjustment mechanism provided on the upper surface of the placement plate, so that the packaging bag can be placed on the placement plate, so that packaging bags of different sizes can be vacuum packaged, and by providing a sealing strip on the bottom surface of the sealing cover plate, the sealing between the sealing cover plate and the placement box can be increased during vacuuming, thereby improving the vacuuming efficiency". When the device performs vacuum packaging on packaging bags of different sizes, it is necessary to adjust the height of the placement plate according to the size of the packaging. When adjusting the placement plate, the first sliding block is usually used to cooperate with the card slot for installation and fixation, but this operation is cumbersome and time-consuming, requiring a lot of manpower and time. Secondly, since the spacing between the card slots is relatively fixed, the height of the placement plate after adjustment is also relatively fixed. This means that it is impossible to make precise adjustments according to the actual size of the packaging bag, resulting in the height of the packaging bag in the placement box being too high or too low, affecting the sealing effect and packaging quality.

[0004] Therefore, we provide a vacuum bag packaging sealing device. Utility Model Content

[0023] Furthermore, slide grooves 11 are provided on both sides of the upper end of the inner wall of the box body 1, and sliders 21 are welded on both sides of the upper cover 2, and the sliders 21 are slidably connected to the inside of the slide grooves 11; when the upper cover 2 is opened and closed, the sliders 21 on both sides of the upper cover 2 slide inside the slide grooves 11, and the slide grooves 11 provide a sliding path for the sliders 21, which can ensure that the upper cover 2 can slide along the path of the slide grooves 11.

[0024] Furthermore, guide blocks 41 are welded on both ends of the placement plate 4, guide rods 5 are welded on the four corners of the inner bottom wall of the box body 1, and the guide blocks 41 are slidably connected to the outside of the guide rods 5; when the placement plate 4 moves, it drives the guide blocks 41 to slide on the outside of the guide rods 5, and the guide rods 5 provide a limiting guide for the guide blocks 41.

[0025] Furthermore, the upper surface of the guide rod 5 is fixedly connected to a limiting block 51 ; the purpose of the limiting block 51 is to limit the guide block 41 to prevent the guide block 41 from slipping off the guide rod 5 when sliding on the outside of the guide rod 5 .

[0026] Furthermore, the driving member 6 includes a threaded rod 61, a reduction motor 62 and a nut seat 63. The threaded rod 61 is rotatably connected to the inside of the box body 1. The reduction motor 62 is connected to the upper end of the threaded rod 61 through a coupling. A fixing ring 13 for fixing the reduction motor 62 is welded on the inner wall of the box body 1. The nut seat 63 is threadedly sleeved on the outer side of the threaded rod 61, and the placement plate 4 and the nut seat 63 are fixedly connected; the driving member 6 provides a power source for the placement plate 4. In this case, the preferred scheme is to use the reduction motor 62 to drive the threaded rod 61 to rotate, thereby driving the outer nut seat 63 to move, and then driving the placement plate 4 to move.

[0027] Furthermore, a soft pad 72 is adhered to one side of the clamping plate 71, and the soft pad 72 is made of silicone material. When the soft pad 72 made of silicone material comes into contact with the packaging bag, it can ensure a firm clamping force while not damaging the packaging bag.

[0028] Furthermore, six groups of photoelectric switches 8 are installed, and are symmetrically installed at the internal upper opening of the box body 1 through a mounting frame 81; the six groups of photoelectric switches 8 are installed in a manner of three groups on each side, which can sense the position of packaging bags of different sizes. When the packaging bag is placed in a biased position, it can also be captured by the photoelectric switch 8.

[0029] Furthermore, right-angle seats 12 are fixedly connected to both sides of the outer wall of the box body 1, a hydraulic rod 29 is fixedly connected to one side of the right-angle seat 12, a fixed plate 22 is fixedly connected to one side of the upper cover 2, and the telescopic ends of the hydraulic rod 29 are fixedly connected to the two ends of one side of the fixed plate 22 close to the upper cover 2; when the upper cover 2 needs to be opened or closed, the hydraulic rod 29 can be driven to perform telescopic movement, thereby realizing the opening and closing of the upper cover 2.

[0030] Working principle: In the first step, the packaging bag is placed on the placement plate 4, and then the hydraulic rod 7 is controlled to operate through the control panel 31. The hydraulic rod 7 drives the telescopic end to extend outward until the clamping plate 71 slightly clamps the packaging bag (the purpose is that when the placement plate 4 drives the packaging bag to move downward, the clamping plate 71 can play an auxiliary supporting role on both sides of the packaging bag to prevent it from falling). In the second step, after the packaging bag is placed on the placement plate 4, the photoelectric switches 8 on both sides detect the presence of the packaging bag. At this time, the control panel 31 controls the reduction motor 62 to operate. The reduction motor 62 drives the threaded rod 61 to rotate through the coupling, thereby driving the nut seat 63 on the outside of the threaded rod 61 to move downward, and then drives the placement plate 4 and the packaging bag placed on the upper end to move downward until the packaging bag is placed on the placement plate 4. The upper end of the bag moves out of the detection range of the photoelectric switch 8. In the third step, when the packaging bag moves out of the detection range of the photoelectric switch 8 (it is necessary to ensure that there is no packaging bag sensing signal from the six groups of photoelectric switches 8), the control panel 31 controls the reduction motor 62 to stop operating. At this time, the upper opening position of the packaging bag is just above the clamping plate 71. In the fourth step, the control panel 31 controls the operation of the hydraulic rod 1 7, and the telescopic end of the hydraulic rod 1 7 drives the clamping plate 71 to clamp the opening of the packaging bag. In the fifth step, after the hydraulic rod 1 7 stops operating, the control panel 31 controls the hydraulic rod 2 9 to retract, thereby driving the upper cover 2 and the sealing machine 3 to move to the upper end of the packaging bag. In the sixth step, the sealing machine 3 and the vacuum pump evacuate, seal, and seal the packaging bag, thereby completing the use process of a vacuum bag packaging sealing device.

[0031] It should be noted that the sealing machine 3 mentioned in the present application and the vacuum pump installed on its upper end can cooperate to complete the vacuuming and sealing functions of the packaging bag, thereby realizing the sealing of the vacuum bag.
