Each milk powder can lid receiving hole 4 can hold one milk powder can lid. The size of the milk powder can lid receiving hole 4 is larger than the size of the milk powder can lid so that there is a gap between the milk powder can lid and the side wall of the milk powder can lid receiving hole 4.

[0024] The sealing vibration mechanism includes a sealing plate 8 fixed to the power output end of the electric push rod 7 and insertable into the perforated plate 5, and a vibrator 9 fixed to the bottom of the sealing plate 8. Specifically, in this embodiment, the sealing plate 8 includes a circular flat plate and an annular insertion block fixed around the periphery of the flat plate.

The aseptic hot air blower 18 is existing equipment that can provide aseptic hot air.

[0029] The method used in this embodiment is as follows:

[0030] 1. Clean the debris from the lid of the milk powder packaging can.

[0031] First, remove the lid 6 from the milk powder can lid holder and place multiple milk powder can lids inside. Then, use the water spray mechanism to spray water into the can, which will initially clean any debris on the can lids. Next, move the power output end of the electric push rod 7 upwards until the sealing vibration mechanism seals the bottom of the can. At this point, the sealing vibration mechanism will block the perforated part at the bottom of the can, allowing the water spray mechanism to spray water into the can. Simultaneously, activate the vibrator 9. The vibrator 9 will then effectively clean the can lids. It should be noted that if the lid 6 is not installed on the can, the vibration intensity of the vibrator 9 should be reduced to ensure that the can lids remain confined within the can under the action of the vibrator 9. Furthermore, depending on actual needs, if increased cleaning intensity is required, the milk powder can lid should first be placed inside the box and filled with water. Then, the can lid should be placed on the box and the lid 6 installed. The vibration intensity of the vibrator 9 should be appropriately increased. After vibrating and cleaning for a certain period, the vibrator 9 should be turned off, and the lid 6 should be opened. The milk powder can lid should then be rinsed using the water spray rinsing mechanism. Finally, the power output end of the electric push rod 7 should be moved downwards to move the sealing vibration mechanism away from the milk powder can lid placement box. Then, the water spray rinsing mechanism should perform a final rinse on the milk powder can lid. At this point, the debris on the milk powder can lid can be cleaned, serving as a pretreatment for subsequent sterilization operations.

[0032] II. Preliminary sterilization using ultraviolet sterilization equipment

[0033] When the lid 6 is not installed on the milk powder packaging can lid placement box, turn on the ultraviolet sterilization mechanism and start the motor 2. The motor 2 will drive the milk powder packaging can lid placement box to rotate. At this time, the milk powder packaging can lid will continue to rotate during sterilization, which can make the ultraviolet rays in the ultraviolet sterilization mechanism irradiate the milk powder packaging can lid more evenly, reduce sterilization dead corners, and improve the sterilization effect.

[0034] 3. Supplemental sterilization using a steam sterilization system.

[0035] The steam sterilization mechanism is activated, and hot steam is sprayed from the steam nozzle 15 to supplement the sterilization of the milk powder packaging can lid.

[0036] IV. Drying the lids of milk powder packaging cans using a sterile hot air system.

[0037] The sterile hot air mechanism is activated, and the hot air blown out from the hot air nozzle 19 can dry the lid of the milk powder packaging can, thus completing the sterilization of the milk powder packaging can lid.

[0038] It should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
