[0002] Tetra Pak packaging is commonly used for packaging liquids. Its inner lining is aluminum foil, and its outer lining is paper, providing ample protection against external bacteria. However, sterilization equipment is required during the production of these packaging boxes. General sterilization equipment has some drawbacks, such as:

[0003] When using conventional sterilization equipment, packaging boxes are usually immersed in hydrogen peroxide for disinfection. However, as the packaging boxes are moved, the local water level of hydrogen peroxide fluctuates, which affects the immersion time of hydrogen peroxide in different locations and is therefore detrimental to the sterilization process of the packaging boxes. Utility Model Content

[0004] The purpose of this invention is to provide a sterilization device for liquid packaging boxes, which can reduce the water level deviation caused by the movement of the packaging boxes and solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a frame and a sterilization tank. The frame is provided with a sterilization tank, a drying mechanism and a winding mechanism in sequence. The two sides of the sterilization tank are inclined. Hydrogen peroxide is stored in the sterilization tank. A flow-suppressing mechanism is provided in the sterilization tank. The drying mechanism is used to spray high-temperature airflow.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0020] Combination Figures 1-4This utility model discloses a liquid packaging box sterilization device, including a frame 1 and a sterilization tank 7. The sterilization tank 7, a drying mechanism and a winding mechanism are arranged sequentially inside the frame 1. The two sides of the sterilization tank 7 are inclined. The sterilization tank 7 stores hydrogen peroxide. A flow suppression mechanism is provided inside the sterilization tank 7. The drying mechanism is used to spray high-temperature airflow. A guide mechanism for supporting the packaging box is provided inside the frame 1.

[0021] It should be noted that the packaging box is guided by a guiding mechanism and wound up by a winding mechanism. Before winding, the packaging box is permeated with hydrogen peroxide, with the side of the packaging box in contact with the liquid immersed in hydrogen peroxide. The immersion time can be adjusted according to the actual situation. Then, the hydrogen peroxide is activated by a drying mechanism to increase the sterilization effect, and the packaging box is dried by a high-temperature airflow. Finally, the packaging box is wound up by the winding mechanism.

[0022] In this embodiment, the flow suppression mechanism includes a baffle 8 and a flow suppression plate 9. The baffle 8 is semi-circular, and the flow suppression plate 9 is provided on the inner side of the baffle 8.

[0023] It should be noted that the sterilization tank 7 stores hydrogen peroxide to sterilize the packaging boxes. At the same time, the packaging boxes will move continuously, and the water flow will change during the movement, resulting in continuous changes in the water level. This reduces the contact time between subsequent packaging boxes. Since the baffle 8 is arc-shaped, the water flow along the baffle 8 will be guided and blocked, thus preventing water ripples from moving along the direction of the packaging box flow. When the water flow along the baffle 8, the flow deflector 9 can further prevent the surface water from flowing.

[0024] In this embodiment, the drying mechanism includes a support frame 10 and an air jet frame 11. The support frame 10 is disposed at the bottom of the frame 1, and the air jet frame 11 is rotatably disposed inside the support frame 10.

[0025] It should be noted that when the device is in use, the support frame 10 supports the jet frame 11, and the support frame 10 and the jet frame 11 can rotate to adjust the angle of the jet frame 11 so that the packaging box is parallel to the jet frame 11, which makes it easier to blow hot air onto the packaging box.

[0026] In this embodiment, exhaust slots 12 are provided at equal intervals on the side of the jet frame 11 near the packaging box, and the exhaust slots 12 are inclined downward.

[0027] It should be noted that the exhaust channel 12 is tilted downwards, which causes the hot airflow to flow downwards along the packaging box, thereby increasing the sterilization effect of the hot air on the packaging box and evaporating the hydrogen peroxide.

[0028] In this embodiment, the winding mechanism includes a collection frame 13 and a collection roller 14. The collection frame 13 is disposed inside the frame 1, and the collection roller 14 is rotatably disposed inside the collection frame 13.

[0029] It should be noted that the collection rack 13 supports the collection roller 14, and the packaging box is wrapped around the surface of the collection roller 14, thereby achieving the winding of the packaging box.

[0030] In this embodiment, the guiding mechanism includes a fixed frame 2, a first guide roller 3, a fixed shaft 4, an electric push rod 5, and a second guide roller 6. The fixed frame 2 is connected to the upper inner end of the frame 1. The first guide roller 3 is arranged between the frame 1 and the fixed frame 2. The two fixed shafts 4 are rotatably arranged inside the frame 1. The fixed shafts 4 are located directly above the sterilization tank 7. The electric push rod 5 is arranged on the side of the fixed shaft 4. The second guide roller 6 is rotatably arranged at the extended end of the electric push rod 5.

[0031] It should be noted that the fixing frame 2 is fixed to the frame 1 by bolts, the first guide roller 3 can guide the packaging box, and the fixed shaft 4 can rotate to adjust the angle of the electric push rod 5 and the second guide roller 6. The electric push rod 5 will adjust the position of the second guide roller 6, thereby adjusting the distance between the second guide roller 6 and the hydrogen peroxide and the distance between the two second guide rollers 6. By adjusting the distance between the two second guide rollers 6, the time for the packaging box to be immersed in hydrogen peroxide can be adjusted.

[0032] Working principle: The processed packaging box is guided by the first guide roller 3 and the second guide roller 6 into the sterilization tank 7. The packaging box is immersed in hydrogen peroxide in the sterilization tank 7 to sterilize it. The immersion time of the packaging box in hydrogen peroxide can be adjusted by adjusting the distance between the two second guide rollers 6. Then, a high-temperature airflow is blown out by the air jet frame 11 to sterilize the packaging box and evaporate the hydrogen peroxide at the same time. Finally, the hydrogen peroxide is collected by the collection roller 14.
