Description
Technical Field
[0001] This utility model relates to the field of packaging bag production technology, and in particular to a sterilization and disinfection device for food production packaging. Background Technology
[0002] Packaging bags are bags used to package various products, making it convenient to transport and store goods during production and distribution. Packaging bags used for food packaging need to be disinfected and sterilized during production to ensure food quality and prevent microbial contamination.
[0003] Chinese utility model patent CN219565744U discloses a sterilization and disinfection device for food production packaging. It sterilizes and disinfects food packaging bags by spraying disinfectant and using ozone. However, the device transports food packaging bags by conveyor belt. When spraying disinfectant, it cannot spray the bottom of the food packaging bags, resulting in poor sterilization on the bottom of the food packaging bags. Furthermore, when using ozone to disinfect food packaging bags, ozone may escape, thereby affecting the air in the working environment and posing a threat to the health of workers.
[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When the device disinfects the compatible packaging tape with ozone, there is a certain distance between the device and the surface of the packaging tape. After the ozone disinfects the food packaging bag, the ozone is sucked into the device through the suction hood. During this process, the ozone may escape, and there may be cases where the ozone is sucked away before it reaches the surface of the food packaging bag, which affects the disinfection effect of the ozone on the surface of the food packaging bag.

[0006] This utility model is achieved by the following technical solution: a sterilization and disinfection device for food production and packaging, including two mounting frames, a conveying component and a cleaning component installed between the two mounting frames, a fixed frame installed above the conveying component, two mounting strips installed inside the fixed frame, fans installed at equal intervals on the surface of the mounting strips, and a cleaning component and an ozone treatment component installed on the top of the fixed frame.
[0007] The conveying assembly includes two conveying rollers connected by two conveyor belts. Conveying strips are fixedly connected at equal intervals between the two conveyor belts. U-shaped placement frames are fixedly connected at equal intervals to the top of the conveyor belts. A gear is sleeved on the outside of the middle shaft of the right conveying roller. A half gear is meshed on the surface of the gear. One end of the middle shaft of the half gear is rotatably connected to the front of the front mounting frame.
[0008] The cleaning assembly includes a water tank installed between two mounting brackets. A water inlet pipe is connected to the front of the water tank, and a water pump is installed on the front of the water tank. A U-shaped pipe is connected to the outlet of the water pump. The U-shaped pipe is fixedly connected to the top of the water tank, and water nozzles are evenly spaced at the top and bottom of the inner wall of the U-shaped pipe.
[0009] The cleaning assembly includes an upper ozone cover, a lower ozone cover, and two limiting slots. Two support rods are fixedly connected to the top of the upper ozone cover, and a movable frame is fixedly connected to the top of each support rod. A rotating rod abuts against the inner wall of the movable frame. A motor is fixedly connected to one end of the rotating rod, and the other end is connected to the outer side of the intermediate shaft of the half-gear via a synchronous belt. Limiting blocks are connected to both the front and back of the upper ozone cover. The limiting blocks are slidably disposed inside the limiting slots, which are fixedly connected to the top of the mounting frame. The right end of the limiting blocks is connected to… There is a connecting pipe. The right end of the front connecting pipe is connected to an adjusting block A. An L-shaped ozone delivery pipe is slidably connected through the inside of the adjusting block A. One end of the L-shaped ozone delivery pipe is connected to an ozone generator. The right end of the back connecting pipe is connected to an adjusting block B. The left side of the adjusting block B is connected to an air intake pipe. An L-shaped ozone absorption pipe is slidably connected inside the adjusting block B. The front and back of the lower ozone cover are both connected to L-shaped limiting pipes. The top of the L-shaped limiting pipe is connected to a corrugated pipe. The top of the corrugated pipe is connected to the bottom of the connecting pipe.
[0010] As a further improvement to the above solution, the ozone treatment component includes an ozone treatment chamber, an air pump installed on the top of the ozone treatment chamber, a heating strip and a filter screen installed inside the ozone treatment chamber, and one end of the ozone treatment chamber is connected to one end of an L-shaped ozone absorption tube for heating the absorbed ozone.
[0011] As a further improvement to the above solution, bearings are fixedly connected to both sides of the top of the mounting frame, and the intermediate shaft of the conveying roller is installed inside the bearings to ensure the normal operation of the conveying roller.
[0012] As a further improvement to the above solution, a support plate is fixedly connected to the bottom of the motor, and the support plate is fixedly connected to the back of the back limiting groove plate to ensure the normal operation of the motor.
[0013] As a further improvement to the above solution, both the surface of the L-shaped ozone delivery tube and the surface of the L-shaped ozone absorption tube are provided with air ports that communicate with the connecting pipe. The top of the surface of the L-shaped ozone absorption tube is provided with an air intake port that communicates with the intake pipe. This facilitates the control of the connection between the air ports on the L-shaped ozone delivery tube and the L-shaped ozone absorption tube and the connecting pipe. The air intake port ensures that the L-shaped ozone absorption tube can draw in air normally when it is not connected to the connecting pipe, thus avoiding excessive negative pressure inside the device.
[0014] As a further improvement to the above solution, the top of the lower ozone cover abuts against the top of the inner wall of the conveyor belt, reducing the escape of ozone from the lower ozone cover.

A rotating bearing is installed on the top of the limiting groove plate, and the mounting rod is installed inside the rotating bearing, ensuring that the rotating rod can normally drive the moving frame to rotate.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. This utility model, by setting up a cleaning component, places food packaging bags between two U-shaped racks. As the conveyor belt transports the food packaging bags, they are gradually moved to the area below the upper ozone cover. With the continuous rotation of the rotating rod, the moving frame moves the upper ozone cover up and down via the support rod. This ensures that when the food packaging bags are transported to the area below the upper ozone cover, they are covered by the ozone cover, and ozone is introduced into the surface of the food packaging bags for disinfection. When the upper ozone cover moves away, it begins to absorb the ozone on the surface of the food packaging bags, reducing ozone loss during ozone disinfection. Furthermore, the ozone is not absorbed during ozone disinfection, thus improving the disinfection effect of the device.
[0018] 2. This utility model, by setting up a conveying component, causes the rotating rod to rotate one revolution, and the intermediate shaft of the half gear to rotate one revolution, thereby causing the gear to drive the conveying roller to rotate half a revolution. This achieves intermittent transportation of food packaging bags, so that the food packaging bags can stop transportation each time they are disinfected, thus improving the disinfection effect of the device on food packaging bags.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0027] Example:
[0028] Please combine Figure 1-5 This embodiment of a sterilization and disinfection device for food production and packaging includes two mounting frames 1. A conveying component and a cleaning component are installed between the two mounting frames 1. A fixed frame 2 is installed above the conveying component.

[0029] The conveying assembly is used to convey food packaging bags. The conveying assembly includes two conveying rollers 4. Bearings are fixedly connected to both sides of the top of the mounting frame 1. The intermediate shaft of the conveying roller 4 is installed inside the bearing to ensure the normal operation of the conveying roller. The two conveying rollers 4 are connected by two conveyor belts 5. Conveying strips 6 are fixedly connected at equal intervals between the two conveyor belts 5. U-shaped placement frames 7 are fixedly connected at equal intervals on the top of the conveyor belts 5. A gear 8 is sleeved on the outside of the intermediate shaft of the right conveying roller 4. A half gear 31 is meshed on the surface of the gear 8. One end of the intermediate shaft of the half gear 31 is rotatably connected to the front of the front mounting frame 1.
[0030] The cleaning assembly is used to clean food packaging bags. The cleaning assembly includes a water tank 9 installed between two mounting brackets 1. The front of the water tank 9 is connected to a water inlet pipe 10. A water pump 11 is installed on the front of the water tank 9. The outlet of the water pump 11 is connected to a U-shaped pipe 12. The U-shaped pipe 12 is fixedly connected to the top of the water tank 9. Water nozzles are evenly spaced at the top and bottom of the inner wall of the U-shaped pipe 12.
[0031] The cleaning assembly is used for ozone sterilization of the surface of food packaging bags. The assembly includes an upper ozone cover 13, a lower ozone cover 14, and two limiting groove plates 15. The top of the lower ozone cover 14 abuts against the top of the inner wall of the conveyor belt 5, reducing ozone leakage from the lower ozone cover 14. Two support rods 16 are fixedly connected to the top of the upper ozone cover 13. A movable frame 17 is fixedly connected to the top of the support rods 16. A rotating rod 18 abuts against the inner wall of the movable frame 17. The rotating rod 18 includes a long rod, with mounting rods fixedly connected to both ends. A rotating bearing is installed on the top of the limiting groove plate 15, and the mounting rods are installed on... The rotating bearing ensures that the rotating rod 18 can drive the moving frame 17 to rotate normally. The length of the mounting rod is half the internal width of the moving frame 17. One end of the rotating rod 18 is fixedly connected to the motor 19, and the bottom of the motor 19 is fixedly connected to the support plate. The support plate is fixedly connected to the back of the back limiting groove plate 15 to ensure the normal operation of the motor 19. The other end of the rotating rod 18 is connected to the outer side of the intermediate shaft of the half gear 31 through a synchronous belt. The front and back of the upper ozone cover 13 are connected to the limiting block 20. The limiting block 20 is slidably set inside the limiting groove plate 15. Plate 15 is fixedly connected to the top of mounting bracket 1. The right end of limiting block 20 is connected to connecting pipe 21. The right end of front connecting pipe 21 is connected to adjusting block A22. An L-shaped ozone delivery pipe 23 is slidably connected through the inside of adjusting block A22. One end of L-shaped ozone delivery pipe 23 is connected to ozone generator 24. The right end of back connecting pipe 21 is connected to adjusting block B25. The left side of adjusting block B25 is connected to suction pipe 26. An L-shaped ozone absorption pipe 27 is slidably connected inside adjusting block B25. Both the surface of L-shaped ozone delivery pipe 23 and the surface of L-shaped ozone absorption pipe 27 are opened. There is an air inlet connected to the connecting pipe 21. The top of the L-shaped ozone absorption tube 27 is provided with an air inlet connected to the suction pipe 26, which facilitates the control of the connection between the air inlets on the L-shaped ozone delivery tube 23 and the L-shaped ozone absorption tube 27 and the connecting pipe 21. The air inlet ensures that the L-shaped ozone absorption tube 27 can absorb air normally when it is not connected to the connecting pipe 21, thus avoiding excessive negative pressure in the device. The front and back of the lower ozone cover 14 are connected to L-shaped limiting tubes 28. The top of the L-shaped limiting tube 28 is connected to a corrugated pipe 29, and the top of the corrugated pipe 29 is connected to the bottom of the connecting pipe 21.
[0032] The implementation principle of the sterilization and disinfection device for food production and packaging in this embodiment is as follows: The motor 19 is started, and the motor 19 drives the rotating rod 18 to rotate. Under the action of the synchronous belt, the rotating rod 18 drives the intermediate shaft of the half gear 31 to rotate. The half gear 31 drives the conveying roller 4 to rotate through the gear 8, so that the rotating rod 18 rotates one revolution and the conveying roller 4 rotates half a revolution, realizing the intermittent transportation of food packaging bags. This allows the food packaging bags to stop transporting each time they are disinfected, increasing the disinfection time of the food packaging bags and improving the disinfection effect of the device on the food packaging bags.
[0033] When transporting food packaging bags, the water pump 11 is started, and the food packaging bags are placed between two U-shaped racks 7. As the conveyor belt 5 is conveyed, the food packaging bags will first move into the inside of the U-shaped tube 12. The surface of the food packaging bags will be cleaned through the water nozzles. After the cleaning is completed, the food packaging bags continue to move to the left. Under the action of the fan, the water on the surface of the food packaging bags will be dried, thus completing the cleaning and drying process of the food packaging bags.
[0034] The food packaging bag then continues to move to the left, transporting it below the upper ozone cover 13. As the rotating rod 18 continues to rotate, the moving frame 17 drives the upper ozone cover 13 to move up and down via the support rod 16. This causes the upper ozone cover 13 to gradually descend as the food packaging bag is transported below it. When the food packaging bag reaches the bottom of the upper ozone cover 13, the half gear 31 disengages from the gear 8, and the rotating rod 18 continues to rotate. The upper ozone cover 13 gradually covers the food packaging bag. Simultaneously, as the upper ozone cover 13 descends, the limiting block 20 drives the adjusting block A22 and adjusting block B25 downwards via the connecting pipe 21, thereby facilitating the connection between the L-shaped ozone absorption tube 27 and the adjusting block B25. When the ozone is misaligned, the air inlet on the L-shaped ozone absorption tube 27 connects with the air inlet tube 26, causing the upper ozone cover 13 and the lower ozone cover 14 to stop absorbing ozone. At the same time, the adjusting block A22 moves along the surface of the L-shaped ozone delivery tube 23, connecting the connecting tube 21 with the L-shaped ozone delivery tube 23, allowing the ozone generated by the ozone generator 24 to be introduced into the interior of the upper ozone cover 13. Under the action of the corrugated tube 29 and the L-shaped limiting tube 28, the ozone is introduced into the lower ozone cover 14 to perform ozone disinfection on the surface of the food packaging bag. This reduces the ozone escape during ozone disinfection of the food packaging bag surface, and at the same time, the ozone is not absorbed during ozone disinfection of the food packaging bag surface, thus improving the disinfection effect of the device.
[0035] As the upper ozone cover 13 moves upward, it drives the adjusting blocks A22 and B25 to move upward as well. During this movement, the L-shaped ozone delivery pipe 23 gradually shifts out of alignment with the adjusting block A22, thus blocking the continued delivery of ozone. Under the action of the adjusting block B25, the suction pipe 26 gradually closes, and the L-shaped ozone absorption pipe 27 gradually connects with the connecting pipe 21, allowing the air pump to begin absorbing ozone. During absorption, the upper ozone cover 13 gradually moves away from the surface of the food packaging bag. After the upper ozone cover 13 rises to a certain height, the half gear 31 begins to mesh with the gear 8, driving the conveying roller 4 to transport the food. As the half gear 31 rotates, the upper ozone cover 13 continues to rise until it returns to its original position. This achieves the goal of stopping the transport of food packaging bags when the upper ozone cover 13 disinfects them, and automatically transporting the next food packaging bag after the disinfection work is completed. This improves the automation effect of the device and ensures the disinfection effect of the food packaging bags.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
