Description

Technical Field

[0001] The utility model relates to the technical field of food packaging, in particular to a sterilization and disinfection device for food production and packaging. Background Art

[0002] Packaging bags refer to bags used to package various supplies, which make it convenient to transport and store goods during the production and circulation process. Packaging bags used for food packaging need to be disinfected and sterilized during production in order to ensure food quality and prevent contamination by microorganisms.

[0003] The patent document with application number CN202021473247.2 and titled "A Disinfection Device for Food Packaging Bag Production" discloses a device that can disinfect packaging bags with disinfectant water and ozone at the same time. During operation, the staff passes the material belt through the feed port, atomizing nozzle, ozone generator, fan, discharge port, between roller 1 and roller 2, and turns on the liquid pump, ozone generator, fan, reduction motor 1 and reduction motor 2 through the electric control box. The reduction motor 1 drives roller 1 to rotate, and the reduction motor 2 drives roller 2 to rotate. Roller 1 and roller 2 cooperate to make the material belt separate from the rotating shaft. The liquid pump spit out the disinfectant water in the liquid storage tank through the atomizing pipe and from the atomizing nozzle to disinfect the material belt. The ozone generator generates and the ozone enters the ozone disinfection box through the pipeline to disinfect the material belt. The fan blows the disinfected material belt dry. However, when using ozone to disinfect the material belt, the ozone is likely to overflow from the shell under the action of the fan inside the shell. When the ozone concentration outside the shell is high, it is likely to cause damage to the operator's body.

[0004] The patent document with application number CN202320461770.0 and titled "A Sterilization and Disinfection Device for Food Production and Packaging" discloses a device that can prevent ozone from escaping outside the main box and causing damage to the operator's body. When in use, the staff places the food packaging bag that needs to be disinfected on the surface of the conveyor bar, and uses the built-in power to drive the roller body to rotate, so that the conveyor bar starts to transport the food packaging bag. When the food packaging bag is transported to the top of the disinfectant tank, the staff uses the liquid delivery mechanism. Under the action of the liquid pump, the disinfectant inside the disinfectant tank is transported by the first connecting pipe, the second connecting pipe and the liquid distribution pipe to the upper and lower nozzles. Finally, under the action of the nozzle, the food packaging bag is sprayed and disinfected at multiple angles. Then the food packaging bag is air-dried by the fan, and then, under the transportation of the conveyor bar, it reaches the inside of the ozone disinfection box body and is disinfected by ozone. When using ozone for disinfection, the staff can turn on the heating wire inside the heating box, and then use the suction mechanism. Under the action of the air pump, the ozone escaping from the outlets on both sides of the ozone disinfection box body reaches the heating box through the suction pipe under the suction force, and the ozone is quickly decomposed into oxygen after heating, and finally discharged through the outlet pipe to avoid the escaped ozone from affecting the safety of the staff. This patent can prevent excessive ozone from escaping, but after collecting the escaping ozone, it needs to be treated with an electric heating wire, so the device consumes a lot of energy during operation. At the same time, the food packaging bag is transported by a conveyor bar. Although most of the surface of the food packaging bag can be sprayed with disinfectant, the part of the food packaging bag that contacts the conveyor bar cannot contact the disinfectant, and the disinfection effect of the food packaging bag needs to be improved.

[0069] The screw rod 14 is rotated and the height of the movable plate 11 is adjusted through the connecting frame 12 , so that the movable plate 11 blocks the spray hole on the lower side of the material belt 25 .

[0070] The motor 5, the motor 8, the liquid pump, the fan 16, the ozone generator 19 and the air pump are started, and the guide roller 4 drives the material belt 25 to move in the box body 1. The disinfectant in the inner box 9 enters the fixed plate 10 and is sprayed onto the surface of the material belt 25 through the spray hole above the movable plate 11. After the fan 16 is started, the disinfectant on the surface of the material belt 25 can drip quickly. The wiping roller 7 can wipe off the excess disinfectant on the material belt 25.

[0071] The air delivery pump forces ozone to flow in the ozone box 17 and the air storage box 18 , thereby reducing the amount of ozone escaping outside the box body 1 .

[0072] The first ozone concentration detector 26 can detect the ozone concentration in the air storage tank 18 in time. When the ozone concentration in the ozone box 17 is lower than the set value, the ozone generator 19 is started, and the ozone generator 19 can replenish ozone into the air storage tank 18 in time.

[0073] The second ozone concentration detector 27 can detect the ozone content at the vertical slot 2 in time. When the ozone concentration at the vertical slot 2 is too high, the gas pump and the ozone generator 19 are stopped in time to prevent excessive ozone from escaping outside the box 1.

[0074] By making the material belt 25 pass between the two vertical parts of the fixing plate 10 in a vertical state, the disinfectant sprayed from the spray hole can adhere to the front and rear sides of the material belt 25, and can fully disinfect the material belt 25. The vertical material belt 25 facilitates the disinfectant thereon to slide off, and when the fan 16 blows air to the material belt 25, the air drying effect of the material belt 25 can be improved.
