Description

Technical Field

[0001] This utility model relates to the field of food production sterilization technology, and in particular to a sterilization device for food safety production. Background Technology

[0002] The food industry refers to the industrial production sector that manufactures food using agricultural and sideline products as raw materials through physical processing or yeast fermentation. Its raw materials are mainly primary products produced by agriculture, forestry, animal husbandry, fishery, and sideline industries. According to the classification catalog formulated by my country in December 1984, it is collectively referred to as the food, beverage, and tobacco manufacturing industry, which is divided into four major sectors: food manufacturing, grain processing, vegetable oil processing, pastry and confectionery manufacturing, sugar refining, and slaughtering and meat processing. In the process of food safety production, it is necessary to sterilize the raw materials used in food safety production through sterilization devices.

[0003] Chinese utility model patent CN221719703U discloses a food production conveyor belt cleaning and disinfection device. The device uses a water pipe frame to spray clean water onto the surface of a brush roller. A motor is then started to rotate the brush roller, cleaning any residue on the conveyor's surface. The water pipe frame does not spray water directly onto the conveyor to prevent excessive water accumulation. A spring force causes a sliding rod to move upwards along a limit rod, ensuring the inclined scraper is in close contact with the conveyor's surface to remove water stains. Finally, a disinfection lamp sterilizes and disinfects the surface of the conveyor.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: During the sterilization process, the device uses a conveyor belt and a sterilizing lamp to sterilize the items. In this process, the bottom of the items is in contact with the surface of the conveyor belt, which makes it difficult for the sterilizing lamp to effectively sterilize the bottom of the items, thus easily affecting the sterilization effect of the device. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a sterilization device for food safety production.

[0006] This utility model is achieved using the following technical solution: a sterilization device for food safety production, including a workbench, a water collection box installed at the bottom of the workbench, sterilization lamps A installed at equal intervals on the top of the workbench, conveyor rollers installed on both sides of the workbench, the two conveyor rollers being connected by a conveyor belt, a cleaning component installed at the bottom of the conveyor belt, a conveyor motor fixedly connected to one end of the left conveyor roller, a U-shaped frame installed on the outside of the workbench, a water tank installed on the top of the U-shaped frame, a pump installed on the front of the U-shaped frame, the input end of the pump being connected to the front of the water tank, sterilization lamps B installed at equal intervals on the front and back of the inner wall of the U-shaped frame, and an actuating component installed on the top of the inner wall of the U-shaped frame.

[0008] The actuating assembly includes a mounting plate fixedly connected to the top of the inner wall of the U-shaped frame. U-shaped levers are slidably connected at equal intervals inside the mounting plate. Adjacent U-shaped levers are connected by a transmission gear. The two ends of the intermediate shaft of the transmission gear are rotatably connected to the top and bottom of the inner wall of the mounting plate, respectively. A threaded cylinder is fixedly connected to the back of the middle U-shaped lever. A threaded rod is threadedly connected inside the threaded cylinder. A bearing is installed on the back of the U-shaped frame. The threaded rod is installed inside the bearing. A drive gear is installed on the outside of the threaded rod. A vertical toothed plate is meshed with the surface of the drive gear. A connecting rod is rotatably connected to the surface of the vertical toothed plate. One end of the connecting rod is rotatably connected to the back of the turntable.

[0009] As a further improvement to the above solution, both the conveying motor and the rotating motor are equipped with support bases at their bottoms to ensure the normal operation of the conveying motor and the rotating motor.

[0010] As a further improvement to the above solution, the back of the U-shaped frame is fixedly connected with a retaining strip, and the front of the vertical toothed plate is provided with a sliding groove. The retaining strip is slidably disposed inside the retaining strip to ensure the normal operation of the vertical toothed plate.

[0011] As a further improvement to the above solution, the surface of the mounting plate is provided with equally spaced openings, and the U-shaped lever is slidably disposed inside the openings. The back of the front U-shaped lever, the front of the back U-shaped lever, and the front and back of the middle U-shaped lever are all fixedly connected with teeth that mesh with the surface of the transmission gear at equal intervals, ensuring the normal operation of the transmission gear.

[0012] As a further improvement to the above solution, sliding grooves are provided on both the front and back sides of the inner wall of the U-shaped frame. A long plate is slidably connected inside the sliding groove. A spring rod is fixedly connected to the bottom of the long plate. The bottom of the spring rod is fixedly connected to the bottom of the inner wall of the sliding groove. A scraper is fixedly connected to the top of the long plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting up a toggle assembly, starts a rotating motor, causing the intermediate shaft of the brush roller to rotate with the turntable. This turntable, through a connecting rod, causes the vertical toothed plate to move up and down vertically. The drive gear, acted upon by the vertical toothed plate, begins to rotate periodically, causing the threaded rod to rotate periodically as well. This causes the U-shaped lever in the middle position to move back and forth inside the mounting plate. During the movement of the U-shaped lever in the middle position, the drive gear causes the other U-shaped levers to move back and forth, resulting in staggered back and forth movements that shift the items on the conveyor belt. This shifts the items' position on the conveyor belt, preventing the mesh on the conveyor belt from affecting the sterilization effect. This allows the sterilizing lamp A to sterilize the items more comprehensively, improving the sterilization effect of the device.

[0017] 2. This utility model, by setting up a cleaning component, activates a pump during the rotation of the brush roller. The pump delivers water from the water tank to the outlet pipe, which wets the brush roller through the nozzle. The brush roller then brushes away impurities from the surface of the conveyor belt. During this process, the cleaning roller rotates under the action of the synchronous belt, absorbing water stains from the surface of the conveyor belt. Simultaneously, under the action of the abutment plate, the water inside the cleaning roller is squeezed and falls into the water collection box, allowing the cleaning roller to continuously absorb water. During this process, the abutment plate, under the action of the spring rod, always abuts against the bottom of the conveyor belt, scraping away impurities from the bottom of the conveyor belt, thus improving the cleaning effect of the device.

The outer side of the cleaning roller 8 is made of sponge material to easily absorb water stains. The surface of the cleaning roller 8 abuts against a retaining plate 20. The bottom of the retaining plate 20 is fixedly connected to the top of the water collection box 2 by two support plates to squeeze the cleaning roller 8 and squeeze out the water inside the cleaning roller 8. One end of the brush roller 7 is fixedly connected to a turntable 9, and the other end of the brush roller 7 is fixedly connected to a rotating motor. The bottom of the conveyor motor and the rotating motor are both equipped with support seats to ensure the normal operation of the conveyor motor and the rotating motor. A water outlet pipe 10 is installed on the right side of the brush roller 7. The surface of the water outlet pipe 10 is connected with nozzles at equal intervals. One end of the water outlet pipe 10 is fixedly connected to the back of the inner wall of the U-shaped frame 5, and the top end of the water outlet pipe 10 is connected to the output end of the pump 6. One end of the cleaning roller 8 is rotatably connected to the back of the inner wall of the U-shaped frame 5. The outer side of the intermediate shaft of the cleaning roller 8 is connected to the outer side of the intermediate shaft of the brush roller 7 by a synchronous belt drive.

[0029] The actuating assembly is used to change the position of the items on the conveyor belt 4, so that the germicidal lamp A can sterilize the bottom of the items more thoroughly. The actuating assembly includes a mounting plate 11 fixedly connected to the top of the inner wall of the U-shaped frame 5. U-shaped levers 12 are slidably connected at equal intervals inside the mounting plate 11. Adjacent U-shaped levers 12 are connected by a transmission gear 13. The surface of the mounting plate 11 has equally spaced openings. The U-shaped levers 12 are slidably disposed inside the openings. The back of the front U-shaped lever 12, the front of the back U-shaped lever 12, and the front and back of the middle U-shaped lever 12 are all fixedly connected at equal intervals with teeth that mesh with the surface of the transmission gear 13, ensuring the normal operation of the transmission gear 13. The two ends of the intermediate shaft are rotatably connected to the top and bottom of the inner wall of the mounting plate 11, respectively. A threaded cylinder 14 is fixedly connected to the back of the U-shaped lever 12 in the middle. A threaded rod 15 is threadedly connected inside the threaded cylinder 14. A bearing is installed on the back of the U-shaped frame 5. The threaded rod 15 is installed inside the bearing. A drive gear 16 is installed on the outside of the threaded rod 15. A vertical toothed plate 17 is meshed with the surface of the drive gear 16. A retaining strip is fixedly connected to the back of the U-shaped frame 5. A sliding groove is opened on the front of the vertical toothed plate 17. The retaining strip is slidably set inside the retaining strip to ensure the normal operation of the vertical toothed plate 17. A connecting rod 18 is rotatably connected to the surface of the vertical toothed plate 17. One end of the connecting rod 18 is rotatably connected to the back of the turntable 9.

[0030] The implementation principle of a sterilization device for food safety production in this embodiment is as follows: the item is placed on the surface of the conveyor belt 4, the conveyor motor is started, and the item is conveyed to the right along the conveyor belt 4.

[0031] The rotating motor is started, causing the intermediate shaft of the brush roller 7 to rotate with the turntable 9. This causes the turntable 9 to move vertically up and down via the connecting rod 18 and the vertical toothed plate 17. The drive gear 16, under the action of the vertical toothed plate 17, begins to rotate periodically, thereby causing the threaded rod 15 to rotate periodically. This causes the U-shaped lever 12 in the middle position to move back and forth inside the mounting plate 11. During the movement of the U-shaped lever 12 in the middle position, the drive gear 16 drives the other U-shaped levers 12 to move back and forth, causing the U-shaped levers 12 to move in a staggered manner. This causes the items on the conveyor belt 4 to be moved, thus shifting the items and changing their position on the conveyor belt 4. This prevents the mesh on the conveyor belt 4 from affecting the sterilization effect of the items, allowing the sterilizing lamp A to sterilize the items more comprehensively and improving the sterilization effect of the device.

[0032] During the rotation of the brush roller 7, the pump 6 is started, which delivers water from the water tank to the outlet pipe 10. The water is then sprayed through the nozzle to wet the brush roller 7. The brush roller 7 brushes the surface of the conveyor belt 4, removing impurities. During this process, the cleaning roller 8 rotates under the action of the synchronous belt, absorbing water stains on the surface of the conveyor belt 4. At the same time, under the action of the abutment plate 20, the water inside the cleaning roller 8 is squeezed and falls into the water collection box 2, allowing the cleaning roller 8 to continuously absorb water. During this process, the abutment plate 20 is always pressed against the bottom of the conveyor belt 4 under the action of the spring rod, scraping away impurities at the bottom of the conveyor belt 4 and improving the cleaning effect of the device.

[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. 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.
