Technical Field

[0001] This application relates to the field of food packaging machine technology, and more specifically, to a rapid cooling and drying device for a food packaging machine. Background Technology

[0002] Food packaging machines are devices that quickly package food after it has been produced. They place the food in a packaging bag and often use a heat sealing method to seal both ends of the bag.

[0003] Because the opening of a heat-sealed packaging bag is in a softened state due to heat, some traditional food packaging machines lack equipment for rapidly cooling and drying the opening. This can easily lead to excessive softening of the bag opening, resulting in additional gaps and rendering the food inedible. This issue needs improvement.

[0004] To address the aforementioned problems, this application provides a rapid cooling and drying device for a food packaging machine. Utility Model Content

[0024] Example:

[0025] This application discloses a rapid cooling and drying device for a food packaging machine. Please refer to [link / reference]. Figure 1The system includes a fixed frame 1, which, in actual use, needs to be fixedly installed at the discharge end of the sealing mechanism of the food packaging machine to facilitate rapid heat dissipation of the heat-sealed packaging bag. Two air-blowing plates 2 are movably installed inside the fixed frame 1. Lifting rods 4 are fixedly installed at the center of the sidewalls of the two air-blowing plates 2 on opposite sides. Each of the two lifting rods 4 has a vertical rod 5 on its opposite side, which is fixedly connected to the fixed frame 1. Each of the two vertical rods 5 has a groove on its adjacent side, with several arc-shaped grooves vertically arranged on the inner wall of the groove. The lifting rods 4 extend into the grooves on the vertical rods 5, and two spring plungers matching the arc-shaped grooves are provided on the outer wall of the lifting rods 4. These spring plungers engage with arc-shaped grooves of different heights. The groove allows for easy fixing of the blower plate 2 at different heights. The two blower plates 2 have openings on their opposite sides, and a fan 3 is installed in each opening. The fan 3 is located to the left of the lifting rod 4. Heat dissipation plates 9 are provided on both the front and rear sides of the blower plate 2. The blower plate 2 has two through holes, and a water pipe 10 is inserted into each through hole. The two ends of the water pipe 10 are connected to a heat dissipation plate 9. Several air outlets are provided on the side of the two blower plates 2 that are close to each other. The blower plate 2 is a hollow plate, and a water pump is installed inside the blower plate 2. The water inlet and outlet of the water pump are connected to a water pipe 10 to facilitate the flow of water in the water pipe 10 and absorb the heat inside the blower plate 2. Two guide components 13 are movably installed in the fixed frame 1.

[0026] Please see Figure 2 and Figure 3 The guide assembly 13 includes two mounting plates 14. Each mounting plate 14 has a rotary motor 15 and a driven shaft 16 on one side close to each other. A conveyor belt 19 is mounted on the outer wall of the rotary motor 15 and the driven shaft 16 located on the same mounting plate 14. A rotating rod 17 is rotatably connected between the two mounting plates 14. The rotating rod 17 consists of a crossbar and two movable rods. The two movable rods are movably mounted on the outer wall of the crossbar. Rollers 18 are movably mounted on the outer wall of the rotating rod 17. There are two rollers 18, each mounted on the outer wall of one of the movable rods in the rotating rod 17. The diameter of the movable rod in the rotating rod 17 is the same as the diameter of the part of the driven shaft 16 that contacts the conveyor belt 19. The rotating rod 17 provides support for the waist of the conveyor belt 19 and restricts the position of the rollers 18.

[0027] Please see Figure 2 and Figure 3Each mounting plate 14 has a fixed top plate 20. Each of the two top plates 20 has several adjustment slots 21 on the side that is close to each other. Each adjustment slot 21 has a movable slider 22. Each slider 22 has a rotatable guide wheel 23. The tops of the sliders 22 are connected to a connecting plate 24. The front and rear sides of the connecting plate 24 have L-shaped notches. Each L-shaped notch has a movable pressing suction cup 25. The pressing suction cup 25 is made of a suction cup and a pressing rod. The pressing rod passes through the connecting plate 24. By pressing the pressing rod, the suction cup is attracted to the top plate 20. The distance between the tops of the guide wheels 23 and the conveyor belt 19 can be adjusted to facilitate the movement of the packaging bag. During the movement, the air blowing plate 2 dissipates heat from the sealing part of the packaging bag.

[0028] Please see Figure 2 and Figure 3 The inner walls on both sides of the fixed frame 1 are provided with lifting grooves 6, and the inner walls on both sides of the blower plate 2 are provided with lifting plates 7 that match the lifting grooves 6, so as to ensure that the blower plate 2 will not shake.

[0029] Please see Figure 2 and Figure 3 Two buffer springs 8 are provided in the two lifting slots 6 on the fixed frame 1, and the two ends of the buffer springs 8 are fixedly connected to the lifting plate 7 and the inner wall of the lifting slot 6, respectively, so that the staff can easily adjust the distance between the two blower plates 2 and save effort.

[0030] Please see Figure 2 and Figure 3 The front and rear side walls of the fixed frame 1 are provided with protrusions 11, each protrusion 11 is provided with a threaded through hole, and each threaded through hole of the protrusion 11 is provided with an adjusting screw 12. Each adjusting screw 12 is connected to a rotating connecting ring on its outer wall, and the side of the rotating connecting ring connected to the adjusting screw 12 is connected to the mounting plate 14. The distance between the two mounting plates 14 can be adjusted by controlling the rotation of the adjusting screw 12.

[0031] The implementation principle of this embodiment is as follows: When in use, the electrical appliances on the device are first started by an external power source. The two adjusting screws 12 are rotated according to the length of the packaging bag to adjust the distance between the two mounting plates 14. Then, the slider 22 is slid in the adjusting groove 21 according to the height of the packaging bag after packaging the food to adjust the distance between the guide wheel 23 and the top of the conveyor belt 19. The height of the guide wheel 23 is fixed by pressing the suction cup 25 to adsorb the upright plate 20. After the packaging bag is heat-sealed, it adheres to the top of the conveyor belt 19 and moves with the conveyor belt 19 through the fixed frame 1. During the process of passing through the fixed frame 1, the air blown by the two blowing plates 2 cools and dries the opening of the packaging bag.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
