[0018] like Figure 1 As shown, the utility model comprises a sterilization box 1, a bath 2 and a paper tube 3 connected to the lower side of the sterilization box 1, a hydrogen peroxide bucket 4 connected to the bath 2 through a pipeline, a high-temperature air sterilizer 5 connected to the paper tube 3 through a pipeline, and an air compressor 6 connected to the high-temperature air sterilizer 5 through a pipeline, and the air compressor 6 is connected to the sterilization box 1 through a pipeline. A paper tube outlet is opened at the lower end of the paper tube 3.
[0019] The bath 2 and the paper tube 3 are both connected to the sterilization box 1. The bath 2 is connected to the right part of the lower side of the sterilization box 1, and the paper tube 3 is connected to the left part of the lower side of the sterilization box 1. The bath 2 is U-shaped as a whole, and the two upper ends of the bath 2 are respectively connected to the sterilization box 1. A packaging material inlet is opened at the lower right side of the sterilization box 1, and the upper part is connected to the air inlet of the air compressor 6 through a pipeline.
[0020] The packaging material 7 enters the sterilization box 1 from the packaging material entrance, then enters from the end of the bath 2 close to the packaging material entrance, and extends from the other end of the bath 2. After that, the packaging material 7 passes through the upper part of the sterilization box 1 and enters the left part of the sterilization box 1. The packaging material 7 moves downward from the left part of the sterilization box. At this time, the packaging material 7 is made into a paper tube 8 for filling. The paper tube 8 enters the paper tube tube 3 downward, and after the filling is completed in the paper tube tube 3, it leaves from the lower opening of the paper tube tube 3. At this point, the sterilization filling of the packaging material 7 is completed. After that, the slitting and transportation operations are completed outside the device.
[0021] The hydrogen peroxide bucket 4 is used to inject hydrogen peroxide into the bath 2 so as to sterilize or disinfect the packaging material. The hydrogen peroxide can kill microorganisms on the surface of the packaging material, thereby ensuring the sterility of the packaging material.
[0022] The air compressor 6 provides compressed air for the high-temperature air sterilizer 5 , and the high-temperature air sterilizer 5 generates high-temperature air to perform high-temperature sterilization on the items in the paper tube 3 .
[0023] The high-temperature air sterilizer 5 is connected to the lower part of the side wall of the paper tube tube 3 through a pipe. The high-temperature air sterilizer 5 is used to heat the air to 600°C. The high-temperature gas generated by the high-temperature sterilizer 5 enters the paper tube tube 3 from the lower part of the side wall of the paper tube tube 3. The high-temperature gas flows through the sterilization box 1 and finally flows out from the right side of the sterilization box 1 and enters the air compressor 6 through the pipe, forming a cycle. During this cycle, the flow direction of the high-temperature gas is opposite to the moving direction of the paper tube 8.
[0024] The high-temperature air sterilizer 5 is also connected to the sterilization box 1 through a pipeline. The air outlet of the pipeline is located in the middle of the sterilization box 1. The direction of the air outlet is opposite to the forward direction of the packaging material 7, so that the high-temperature air can be blown more evenly in the opposite direction of the packaging material 7, ensuring that when the packaging material 7 passes through the sterilization box, its surface can be blown evenly and effectively, thereby further improving the sterilization effect. In addition, the packaging material 7 is sterilized again before being made into a paper tube to ensure its sterile state.
[0025] The inner cavity of the sterilization box 1 is in the shape of a groove as a whole, and includes a left chamber 13 extending downward to communicate with the paper tube 3, a right chamber 11 extending downward to communicate with the bath 2, and a middle channel 12 connecting the left chamber and the right chamber.
[0026] like Figure 2 and Figure 3As shown, an opening is provided in the middle of the upper end of the sterilization box 1, and a cover plate 14 is provided at the opening. The cover plate 14 has a lower concave portion extending into the sterilization box 1, and an upper packaging material clamping plate 15 is provided at the lower end of the lower concave portion of the cover plate 14. A corresponding lower packaging material clamping plate 16 is provided in the sterilization box 1. The packaging material 7 passes through the upper packaging material clamping plate 15 and the lower packaging material clamping plate 16, ensuring that the packaging material 7 can remain stable during the sterilization process, without moving or deforming, so as to effectively perform the sterilization process. The cover plate 14, the upper packaging material clamping plate 15 and the lower packaging material clamping plate 16 make the sterilization box 1 have a narrower upper channel, and the narrower middle channel can reduce the outflow speed of the high-temperature air in the left chamber, ensuring that the high-temperature gas at positive pressure is maintained in the sterilization box 1, which is conducive to maintaining a positive pressure sterile environment in the left chamber, and preventing external air from entering the paper tube tube 3 from the gap between the paper tube outlet at the lower end of the paper tube tube 3 and the paper tube 8. The size of the middle channel can be adjusted by using upper packaging material clamps 15 of different thicknesses. A sealing ring 17 is provided at the contact position between the cover plate 14 and the sterilization box 1 to ensure a close fit and sealing effect between the two.
