[0022] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0023] like Figure 1-7As shown, a cap sterilization machine includes a frame 1, a feeding mechanism 2 for sequentially conveying bottle caps and a drying mechanism 3 for drying bottle caps, both mounted on the frame 1. The feeding mechanism 2 and the drying mechanism 3 are located on different height planes, with the feeding mechanism 2 positioned above the plane of the drying mechanism 3. A feeding channel is provided between the feeding mechanism 2 and the drying mechanism 3 for conveying bottle caps from the feeding mechanism 2 to the drying mechanism 3. The feeding mechanism 2 is equipped with a sterilization component 5 for sterilizing the bottle caps within it. A cover 36 is provided on the feeding mechanism 2, the feeding channel, and the drying mechanism 3. A sterilization component 5 for sterilizing the bottle caps within the feeding channel is provided at the feeding channel. Two sterilization components 5 are respectively mounted on the cover 36 of the feeding mechanism 2 and the feeding channel. The feeding channel includes a first guide rail 4 for conveying bottle caps.

[0024] By staggering the feeding mechanism 2 and the drying mechanism 3 in the height direction, the structure is compact, significantly reducing the overall space occupied by the equipment. Two sterilization components 5 are used to sterilize the bottle caps in the feeding mechanism 2 and the first guide rail 4 respectively, resulting in good sterilization effect. The bottle caps in the feeding mechanism 2 are transported to the drying mechanism 3 through the first guide rail 4, effectively reducing the turning movement of the bottle caps on the moving path and making it less likely for the caps to jam during the movement. Furthermore, the bottle caps in the feeding mechanism 2 and the first guide rail 4 are in a semi-closed state by two machine covers 36 set on the feeding mechanism 2 and the first guide rail 4, which prevents the gas used for sterilization from escaping and significantly improves the sterilization efficiency.

[0025] The feeding mechanism 2 and the drying mechanism 3 are respectively provided with a first inlet 6, a first outlet 7, a second inlet 8, and a second outlet 9 for bottle caps to enter and exit. The first inlet 6 is provided with a first cap channel 10 that connects to external equipment for conveying bottle caps. The two ends of the first guide rail 4 are respectively connected to the first outlet 7 and the second inlet 8. The second outlet 9 is provided with a second guide rail 11 for the bottle caps to be flipped, dried a second time, and conveyed to subsequent processing equipment. The first guide rail 4 and the second guide rail 11 are composed of several cables, which together form a channel for the movement of the bottle caps.

[0026] The feeding mechanism 2 includes a base 12 fixedly mounted on the frame 1 to support the moving bottle caps. The base 12 is fixedly mounted on the frame 1 by a mounting bracket. Two first star wheels 13 and second star wheels 14 are rotatably mounted on the base 12 and rotate in contact with each other. The outer periphery of the first star wheel 13 and the second star wheel 14 are respectively provided with a first notch 15 and a second notch 16 for engaging the bottle caps. The sterilization component 5 is positioned directly opposite the second notch 16 on the second star wheel 14. The base 12 is fixedly provided with a first guide plate 17 and a second guide plate 18 surrounding the outer periphery of the first star wheel 13 and the second star wheel 14, respectively. The base 12 is provided with a guide member 19 for the bottle caps on the second star wheel 14 to enter the first discharge port 7. The frame 1 is provided with a first power source 20 that drives the first star wheel 13 and the second star wheel 14 to rotate synchronously. A cover 21 is fixedly installed above the base 12. The cover 21 is fastened above the gap between the first notch 15 and the first guide plate 17, and above the gap between the second notch 16 and the second guide plate 18. A drive wheel 22 is fixedly installed at the lower end of the first star wheel 13 and the second star wheel 14 respectively. The two drive wheels 22 are always meshed with each other. The first power 20 drives the drive wheel 22 to rotate, causing the first star wheel 13 and the second star wheel 14 to rotate in opposite directions, thus realizing the conveying movement of the bottle cap. Several protrusions 23 for engaging the bottle cap are provided inside the second notch 16. The bottle caps are respectively engaged in the first notch 15 and the second notch 16. Driven by the first power 20, they move within the channel formed by the base 12, the first star wheel 13, the first guide plate 17, and the cap 21, and then enter the channel formed by the base 12, the second star wheel 14, the second guide plate 18, and the cap 21. The bottle caps always move above the base 12 within the feeding mechanism 2. When the first notch 15 on the first star wheel 13 and the second notch 16 on the second star wheel 14 are aligned, the two sides of the bottle caps are engaged in the first notch 16. Within the first notch 15 and the second notch 16, the protrusions 23 reduce the contact area of ​​the cap, making the cap sterilization more thorough. As the second star wheel 14 rotates, the cap moves from the first notch 15 to the second notch 16. Finally, the guide 19 guides the cap out of the second notch 16 and into the first guide rail 4 through the first outlet 7. Under the action of gravity and the push of subsequent caps, the cap moves downward along the first guide rail 4, passes through the second inlet 8, and enters the drying mechanism 3. During its movement within the first guide rail 4, it undergoes a second vaporization sterilization through the sterilization component 5.

[0027] The drying mechanism 3 includes a drive shaft rotatably mounted on a power base 24 and an upper drying assembly 25, an upper support 26, a guide plate 27, a turntable 28, and a lower support 29 arranged sequentially from top to bottom along the length of the drive shaft. The power base 24 is provided with a second power 30 that drives the drive shaft to rotate. Both the first power 20 and the second power 30 are motors. The lower support 29 is fixedly mounted with a lower drying assembly 31 that dries the lower end of the bottle cap on the turntable 28. The lower end of the guide plate 27 is fixedly mounted with a second cap channel 32 that causes the bottle cap to move in a spiral shape under the drive of the turntable 28. The second inlet 8 and the second outlet 9 are located on the guide plate 27 and at both ends of the second cap channel 32. The upper drying assembly 25, the upper support 26, the guide plate 27, the second cap channel 32, the lower support 29, and the lower drying assembly 31 are fixedly mounted on the frame 1. The turntable 28 rotates with the drive shaft under the drive of the second power 30. The turntable 28 is provided with air holes 33 that penetrate vertically through the turntable 28, and these air holes 33 cover the entire turntable 28. The lower end of the upper drying assembly 25 is provided with multiple downward-extending air outlet pipes 34 for drying the bottle caps on the turntable 28. A drying rack 35 is provided on one side of the second guide rail 11 for further drying the bottle caps inside the second guide rail 11. After passing through the second feed port 8, the bottle caps enter the second cap channel 32. As the turntable 28 rotates, the bottle caps move along the second cap channel 32 to the second discharge port 9. During the movement, the upper drying assembly 25 and the lower drying assembly 31 dry the moving bottle caps. After drying in the second cap channel 32, the bottle caps are sent into the second guide rail 11, where they are flipped over and then dried a second time by the drying rack 35 on one side of the second guide rail 11.

[0028] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications to the specification derived therefrom are still within the protection scope of this utility model.
