Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] Depend on Figures 1 to 3 This invention discloses an ultraviolet sterilization device for food processing, comprising a sterilization chamber 1, a control panel 2 fixedly mounted at one end of the top front of the sterilization chamber 1, a drive motor 3 fixedly mounted at the middle position of one end of the front of the sterilization chamber 1, a mesh conveyor belt 4 rotatably mounted at the middle position inside the sterilization chamber 1 and connected to the drive motor 3, a plurality of ultraviolet sterilization lamps 5 mounted at the bottom inside the sterilization chamber 1, a plurality of ultraviolet sterilization lamps 6 mounted at the top inside the sterilization chamber 1, and a plurality of auxiliary turning mechanisms 7, the auxiliary turning mechanisms being powered by servo motors. The system comprises a motor 8, a rotating shaft 9, a rotating support body 10, a rubber turning plate 11, and an elastic limiting component 12. The servo motor 8 is fixedly connected to the side of the sterilization chamber 1 away from the control panel 2. The rotating shaft 9 is rotatably connected to the inside of the sterilization chamber 1 and fixedly connected to the output shaft of the servo motor 8. The rotating support body 10 is sleeved on the rotating shaft 9 and fixedly connected to it. The rubber turning plate 11 is inserted into the bottom end of the rotating support body 10. The elastic limiting component 12 is fixedly connected to the bottom end of one side of the rotating support body 10 and is attached to the rubber turning plate 11.
[0024] Food is conveyed by the mesh conveyor belt 4 and enters the sterilization chamber 1. It is sterilized by ultraviolet sterilization lamp 5 and ultraviolet sterilization lamp 6. During the sterilization process, the rotating shaft 9 and the rotating support body 10 can be driven to rotate by the servo motor 8. The rotating support body 10 drives the rubber turning plate 11 to rotate. The continuous rotation of the rubber turning plate 11 turns the food. Alternatively, the servo motor 8 can drive the rubber turning plate 11 to rotate to a certain angle so that the rubber turning plate 11 is in continuous contact with the top surface of the food to achieve continuous turning. The elastic limiting component 12 can elastically limit the rubber turning plate 11 to improve the turning effect.
[0025] Depend on Figures 1 to 5 As shown, both ends of the rotating shaft 9 are inserted into the sterilization box 1 and rotatably connected to the sterilization box 1 through the bearing 13. The elastic limiting component 12 is composed of two elastic metal arms 14 and a strip force plate 15. The strip force plate 15 is fixedly connected to the rotating support body 10 through the elastic metal arms 14. The elastic metal arms 14 have an arc-shaped structure. The bottom end of the rotating support body 10 is provided with a strip groove 16 that matches the rubber turning plate 11. Several bolts 17 connected to the rubber turning plate 11 are inserted through the bottom end of one side of the rotating support body 10. The rubber turning plate 11 is composed of a snap-fit strip 18 and an arc-shaped rubber plate 19. The snap-fit strip 18 is inserted through the strip groove 16 and connected to the bolts 17. The arc-shaped rubber plate 19 is fixedly connected to the bottom end of the snap-fit strip 18. Several protruding ribs 20 are fixedly provided on the bottom surface of the arc-shaped rubber plate 19.
[0026] The elastic metal arm 14 can undergo elastic deformation. The strip-shaped force plate 15 fits against the side of the rubber flipping plate 11, thereby limiting the rubber flipping plate 11 and preventing excessive deformation of the rubber flipping plate 11 from affecting the flipping effect. The strip-shaped slot 16 and bolt 17 can install the rubber flipping plate 11 and can also replace the rubber flipping plate 11 later. The arc-shaped rubber plate body 19 and the convex rib 20 can increase the friction with the food during the flipping process and prevent slippage.
[0027] Depend on Figure 1 and Figure 2 As shown, a door 1 21 is provided at the top of the front of the sterilization box 1, a door 22 is provided at the bottom of the front of the sterilization box 1, and inlet and outlet ports 23 are provided at both ends of the sterilization box 1. Several rubber protrusions 24 are fixedly provided on the outer surface of the mesh conveyor belt 4.
[0028] The rubber protrusion 24 can limit the movement of food, allowing it to turn over within a certain range.
[0029] In operation, the system is equipped with a sterilization chamber, drive motor, mesh conveyor belt, UV sterilization lamp one, and UV sterilization lamp two to transport food and perform UV sterilization during the transport process, improving food safety. An auxiliary turning mechanism, consisting of a servo motor, rotating shaft, rotating support, rubber turning plate, and elastic limiting components, turns the food during sterilization, ensuring full contact between the food surface and UV light, thus improving the comprehensiveness of sterilization. The elastic limiting component, consisting of two elastic metal arms and a strip-shaped force plate, provides elastic restraint to the rubber turning plate, improving the turning effect. The rubber turning plate, consisting of strip grooves, bolts, and a locking strip and an arc-shaped rubber plate, allows for disassembly and replacement. The arc-shaped rubber plate and protruding ribs enhance contact with the food, increase contact resistance, and prevent slippage, further improving the turning effect.
