Detailed Embodiment

[0026] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] As Figure 1 , Figure 2 shown, a sterilizing device for a bread packaging includes a sterilization box 1, a conveyor belt 2, an atomizer 3, an atomizing nozzle 4, and an ultraviolet lamp 5.

[0028] As Figure 1 , Figure 2 shown, the sterilization box 1 is provided with a hollow interior. A feeding conveyor 11 is horizontally arranged on the upper side wall at one end of the sterilization box 1, and a discharging conveyor 12 is horizontally arranged on the lower side wall at the other end.

[0029] As Figure 1 , Figure 2 shown, the conveyor belt 2 is horizontally arranged in multiple layers inside the sterilization box 1. Adjacent layers of the conveyor belt 2 are arranged in a staggered manner, and the conveying directions are opposite. Moreover, multiple conveyor belts 2 form a serpentine conveying channel connecting the feeding conveyor 11 and the discharging conveyor 12, and the movement time of the packaging in the conveying channel is greater than 30 minutes.

[0030] As Figure 1 , Figure 2As shown, a transfer plate 21 is inclined downward at the end position of each conveyor belt 2, and a guiding plate 22 is inclined downward at the starting end position of each conveyor belt 2. The included angle between the transfer plate 21 and the guiding plate 22 is 75° - 85°.

[0031] As Figure 1 , Figure 2 shown, the atomizer 3 is arranged outside the sterilization box 1 and is used for atomizing the sterilizing liquid. The sterilizing liquid is preferably alcohol, which can volatilize quickly without residue. Even if there is residue, it will not cause harm to people. The atomizing nozzle 4 is horizontally arranged in the sterilization box 1 and is located above each conveyor belt 2. Ultrasonic atomizing nozzles are used on the atomizing nozzle 4, and the atomizing nozzles 4 of the bottom two layers can be changed to air pipes with ordinary nozzles to realize the air drying after the sterilization and disinfection of the packages, keeping the surfaces of the packages dry. The ultraviolet lamps 5 are arranged on the inner walls of both sides of the sterilization box 1 and are aligned between the adjacent conveyor belts 2 on both sides.

[0032] As Figure 1 , Figure 2 shown, an air purifier 6 is arranged on the sterilization box 1, and the inlet end and the outlet end of the air purifier 6 are respectively communicated with both sides of the sterilization box 1.

[0033] When it is necessary to sterilize and disinfect the bread packages, the feeding conveyor 11 is used to transfer the packages into the sterilization box 1. At this time, the packages are transferred into the topmost conveyor belt 2 and move on the conveyor belt 2. When the packages move to the end position of the conveyor belt 2, the packages automatically slide onto the transfer plate 21 and slide downward along the transfer plate 21.

[0034] During the sliding process, a corner position of the package gradually touches the guiding plate 22, and under the guiding action of the inclined guiding plate 22, the package can be automatically turned over, making the side that was originally in contact with the conveyor belt 2 face the other side. Thus, through the transfer of multiple conveyor belts 2 and the cooperation of the transfer plate 21 and the guiding plate 22, the package can be continuously turned over in the sterilization box 1.

[0035] Meanwhile, during the transfer of the packages, the atomizer 3 atomizes the sterilizing liquid and sprays it into the sterilization box 1 along the atomizing nozzle 4. And a double sterilization and disinfection method of atomization and ultraviolet irradiation is adopted to achieve the complete sterilization of the bread packages, avoiding the packages carrying microorganisms and contaminating the bread, and ensuring the quality and quality of the bread. The sterilization method does not adopt the traditional high-temperature method, which can avoid the packages being damaged by heat.

[0036] And after the sterilization of the package, it can be transported along the discharge conveyor and enter the aseptic packaging workshop to realize the packaging of bread. At the same time, during the sterilization process, the air purifier 6 can timely extract the air containing the sterilizing liquid in the sterilizing box 1, and after purification, the clean air re-enters the sterilizing box 1 to realize the gas circulation. At the same time, it ensures that the concentration of the sterilizing liquid in the sterilizing box 1 tends to be consistent, guarantees the sterilization effect, and also avoids the condensation of excessive sterilizing liquid into water droplets and polluting the package.

[0037] As Figure 1 、 Figure 3 shown, a support frame 31 is vertically arranged on the atomizer 3, a suspension 32 is horizontally arranged on the support rod, a mounting head 33 is arranged on the suspension 32, a liquid replenishing bottle 34 is threadedly arranged on the mounting head 33, and a liquid replenishing channel 35 communicating the mounting head 33 and the liquid injection port of the atomizer 3 is arranged in the support frame 31 and the suspension 32.

[0038] As Figure 3 shown, a switch mechanism 7 for controlling the opening and closing of the liquid replenishing channel 35 is arranged on the support frame 31. The switch mechanism 7 includes a switch plate 71, a motor 72 and a crank connecting rod 73. The switch plate 71 is horizontally slidably connected in the support frame 31 and is used to cover the liquid replenishing channel 35. The motor 72 is arranged on the outer wall of the support frame 31, and the crank connecting rod 73 is arranged between the switch plate 71 and the shaft of the motor 72.

[0039] As Figure 3 shown, a pressure pipe 36 is arranged on the suspension 32 beside the mounting head 33, and a pressure channel 37 communicating the pressure pipe 36 and the mounting head 33 is arranged on the suspension 32. A piston 38 is vertically slidably connected in the pressure pipe 36, and a screw 39 is threadedly connected to the pressure pipe 36. The lower end of the screw 39 is rotatably connected to the upper end surface of the piston 38.

[0040] When the package is sterilized, the sterilizing liquid in the atomizer 3 will gradually decrease. Therefore, before the atomizer 3 works, first fill the atomizer 3 with the sterilizing liquid, and then rotate and install the liquid replenishing bottle 34 filled with the sterilizing liquid on the mounting head 33. Subsequently, rotate the screw 39 to control the piston 38 to move downward. At this time, the air in the pressure pipe 36 will be injected into the liquid replenishing bottle 34, making the liquid replenishing bottle 34 generate a positive pressure.

[0041] When the atomizer 3 starts to work, start the motor 72. At this time, under the action of the crank connecting rod 73, the switch plate 71 makes a horizontal reciprocating motion. At this time, the switch plate 71 controls the continuous opening and closing of the liquid replenishing channel 35, and enables the sterilizing liquid in the liquid replenishing bottle 34 to be continuously injected into the atomizer 3, ensuring the continuous operation of the atomizer 3 and realizing the continuous sterilization and disinfection of the package without stopping the machine.

[0042] When it is necessary to replace the liquid replenishing bottle 34, since there is always bactericidal liquid in the atomizer 3, even if the liquid replenishing bottle 34 is replaced, it will not affect the operation of the atomizer 3, thus ensuring the continuous sterilization and disinfection of the packaging unit.

[0043] As Figure 3 shown, the suspension 32 is rotatably connected to the support frame 31, and a locking mechanism 8 for fixing it to the support frame 31 is provided on the suspension 32.

[0044] As Figure 3 shown, the locking mechanism 8 includes a locking disc 81, a locking rod 82 and a pull ring 83. The locking disc 81 is arranged on the outer wall of the suspension 32, and the locking rod 82 is horizontally slidably connected to the locking disc 81. A locking hole 84 for the locking rod 82 to be screwed into is provided on the support frame 31, and the pull ring 83 is arranged at the end of the locking rod 82.

[0045] Since the liquid replenishing bottle 34 has its opening facing downward during use, when installing the liquid replenishing bottle 34, the locking rod 82 can be first loosened, and then the suspension 32 is controlled to rotate until the installation head 33 faces downward, and then the liquid replenishing bottle 34 is installed and fixed. Finally, the suspension 32 is controlled to rotate in the reverse direction, and the locking rod 82 is tightened so that the locking rod 82 is inserted into the locking hole 84 to realize the fixation of the suspension 32. At this time, the opening of the liquid replenishing bottle 34 faces downward, thus avoiding the phenomenon of spilling during the replacement of the liquid replenishing bottle 34 and realizing the stable replacement and rapid installation of the liquid replenishing bottle 34.

[0046] The specific embodiments are only explanations of the present invention, and they are not limitations on the present invention. Those skilled in the art can make modifications without creative contributions to the embodiments according to needs after reading this specification, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
