Description

Technical Field

[0001] The present application relates to the technical field of food packaging, and in particular to a sealing machine for food packaging. Background Art

[0002] A sealing machine is a machine that seals containers filled with packaging materials. After the product is loaded into the packaging container, in order to keep the product sealed and preserved, maintain product quality, and avoid product loss, the packaging container needs to be sealed. This operation is completed on a sealing machine. Simply put, a sealing machine refers to a machine that seals the container after the packaging container is filled with products.

[0003] Patent announcement number CN219447504U proposes a sealing machine for food packaging, in which the place where the packaging bag needs to be sealed is placed in the hot melt opening. At this time, the electric telescopic rod drives the moving plate to make the slider squeeze the spring on the fixed shaft, and the moving plate drives the hot melt sealer to seal the packaging bag. After the sealing is completed, the electric telescopic rod quickly returns to its original position, and the slider drives the moving plate through the elastic force of the spring to make the hot melt sealer quickly return to its original position, thereby effectively preventing the hot melt sealer from contacting the packaging bag for too long and sticking to the hot melt sealer, thereby improving the packaging effect.

[0004] In the above patent, the elastic force of the spring drives the movable plate to reset. However, if the packaging bag is already bonded to the hot melt sealer, the packaging bag is likely to move with the movement of the movable plate, and the packaging bag and the hot melt sealer cannot be quickly separated, which makes it inconvenient to seal the packaging bag and reduces the sealing efficiency of the packaging bag. Therefore, those skilled in the art provide a food packaging sealing machine to solve the problems raised in the above background technology. Utility Model Content

[0029] In this embodiment, when the packaging bag is sealed, the sealing part of the packaging bag is extended into the hollow box 1 through the hot melt opening 2, and then the two movable plates 4 are driven to move toward each other under the movement of the two electric telescopic rods 3, that is, the two hot melt sealers 5 are driven to move toward each other, so that the hot melt sealers 5 squeeze and heat the packaging bag to seal, and when the movable plate 4 drives the hot melt sealer 5 to move and seal, with the cooperation of the pulling component 9, the U-shaped frame 6 and the shovel plate 7 are moved away from the hot melt sealer 5. When the sealing is completed, the movable plate 4 is reset. At this time, under the movement of the elastic component 8, the U-shaped frame 6 and the shovel plate 7 are driven to approach the hot melt sealer 5, and the shovel plate 7 can be used to shovel the bonding part between the hot melt sealer 5 and the packaging bag, thereby facilitating the separation of the packaging bag, facilitating the sealing of the packaging bag, and improving the sealing efficiency of the packaging bag.

[0030] In a further embodiment, Figure 2-3 As shown, the elastic component 8 includes a first slider 81 fixedly arranged at both ends of the U-shaped frame 6, and a first slide groove 82 for the first slider 81 to slide is opened on both sides of the movable plate 4.

The pulling component 9 includes a pull rope 91 fixedly arranged between the U-shaped frame 6 and the inner wall of the hollow box 1, and a pulley 92 for pulling the pull rope 91 is fixed on one side of the movable plate 4.

[0031] When the electric telescopic rod 3 drives the moving plate 4 and the hot melt sealer 5 to move for sealing, the moving plate 4 is away from the inner wall of the hollow box 1, and then the U-shaped frame 6 and the shovel plate 7 are driven to move to the side of the moving plate 4 under the cooperation of the pull rope 91 and the pulley 92.

At this time, the U-shaped frame 6 and the shovel plate 7 are away from the hot melt sealer 5, and the packaging bag can be sealed by the hot melt sealer 5. When the sealing is completed, the electric telescopic rod 3 drives the moving plate 4 and the hot melt sealer 5 to return to the original position. Near the inner wall of the hollow box 1, if the packaging bag is adhered to the hot-melt sealer 5 and moves with it, the pull rope 91 is in a relaxed state at this time, and then under the elastic action of the spring 83, the first slider 81 is driven to reset, and the first slider 81 drives the U-shaped frame 6 and the shovel plate 7 to reset, so that the shovel plate 7 moves toward the hot-melt sealer 5, and the shovel plate 7 can be used to shovel the bonding point between the hot-melt sealer 5 and the packaging bag, so as to facilitate the rapid separation of the hot-melt sealer 5 and the packaging bag, thereby facilitating the sealing of the packaging bag and improving the sealing efficiency of the packaging bag.

[0033] When the packaging bag is sealed, the movement of the moving component 12 drives the reciprocating movement of the air duct 10, and the air duct 10 drives the reciprocating movement of the nozzle 11. At the same time, air is supplied to the air duct 10 and the nozzle 11 through the air supply component 13, and the sealing part of the packaging bag can be blown back and forth through the nozzle 11, thereby facilitating the rapid cooling of the sealing part of the packaging bag and improving the cooling efficiency of the packaging bag.
