Description

Technical Field

[0001] This invention relates to the field of bottle cap sterilization equipment, specifically a bottle cap rotary sterilization device. Background Technology

[0002] Bottle cap sterilization equipment is a key component of aseptic filling production lines. It efficiently kills microorganisms on the surface of bottle caps before sealing to meet commercial sterility requirements, thus ensuring product quality and safety within its shelf life. Because its sterilization process requires sufficient exposure time, the equipment is typically designed with a long, linear structure. This occupies a large production space, limiting the flexibility of the production line layout. When caps are fed intermittently, insufficient residence time in the sterilization zone or uneven agent application can lead to incomplete sterilization. Furthermore, this structure also presents significant challenges for daily operation, monitoring, cleaning, and maintenance. Summary of the Invention

[0003] In view of the shortcomings of existing bottle cap sterilization equipment, the technical problem to be solved by the present invention is to provide a bottle cap rotary sterilization device that can reduce the space occupied while ensuring the contact time between the sterilizing agent and the bottle cap, thus ensuring the sterilization effect.

[0004] To achieve the above objectives, according to one aspect of the present invention, the present invention is achieved through the following technical measures: a bottle cap turntable sterilization device, comprising a cylindrical body, wherein the cylindrical body is provided with a cap inlet and a cap outlet, and a sterilization component, an isolation grid, and a turntable are respectively provided from top to bottom inside the cylindrical body, wherein the isolation grid is provided with a material drop groove and a ventilation groove, and a grid plate is provided at the bottom of the isolation grid, the grid plate being spiral-shaped, the isolation grid covering the turntable, forming a spiral sterilization channel between the turntable and the isolation grid, and a material discharge channel is provided between the turntable and the cap outlet.

[0005] Furthermore, the top of the cylinder is covered by a cylinder cap, the top of which has an inlet hole. The cylinder drop trough is located in the middle of the turntable. The starting point of the sterilization channel is opposite to the drop trough, the ending point is on the outer ring of the turntable, and it extends outward to form a discharge channel. The discharge channel is led out from the cylinder's outlet.

[0006] Furthermore, the isolation fence is fixed to the cylinder by fixing posts.

[0007] Compared with the prior art, the advantages of the present invention are as follows: The bottle cap rotary sterilization device changes the linear sterilization structure to a spiral sterilization structure, which reduces the space occupied by the sterilization structure, improves the flexibility of the production line layout, and at the same time ensures the contact time between the sterilizing agent and the bottle cap, avoiding incomplete sterilization due to insufficient residence time or uneven agent reception when the caps are fed intermittently.

[0010] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0011] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "bottom", "top", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0012] Please refer to Figure 1-2 This embodiment provides a bottle cap turntable sterilization device, including a cylindrical body 1, the top of which is covered by a cylindrical cap 2. The top of the cylindrical cap 2 is provided with a cap inlet hole 3. Inside the cylindrical body 1, from top to bottom, there are sterilization components 4, an isolation grid 5, and a turntable 6. The isolation grid 5 is provided with a drop trough 7 and a ventilation trough 8. The drop trough 7 is located in the middle of the turntable 6. The ventilation trough 8 is evenly distributed on the isolation grid 5. The bottom of the isolation grid 5 is provided with a grid plate 9. The grid plate 9 is spiral-shaped. The isolation grid 5 covers the turntable 6, forming a spiral sterilization channel 10 between the turntable 6 and the isolation grid 5. The starting point of the sterilization channel 10 is set opposite to the drop trough 7, the ending point is at the outer ring of the turntable 6, and it extends outward to form a discharge channel 11. The discharge channel 11 is led out from the cap outlet 12 of the cylindrical body 1.

[0013] This embodiment provides a bottle cap rotary sterilization device. In use, bottle caps fall onto the rotary table 6 through the cap inlet 3 and the drop chute 7. The rotary table 6 rotates while the isolation grid 5 remains stationary. Driven by the rotary table 6 and guided by the spiral grid plates 9 of the isolation grid 5, the bottle caps move in the sterilization channel 10 toward the discharge channel 11. At the same time, the sterilization component 4 sprays sterilization gas from above the isolation grid 5. The sterilization gas passes through the ventilation groove 8 to sterilize the bottle caps moving in the opposite direction. Each bottle cap falls from the cap outlet 12 after passing through the entire spiral sterilization channel 10.

[0014] This embodiment provides a bottle cap rotary sterilization device that transforms a linear sterilization structure into a spiral sterilization structure, reducing the space occupied by the sterilization structure, improving the flexibility of the production line layout, and ensuring the contact time between the sterilizing agent and the bottle cap, thus avoiding incomplete sterilization due to insufficient residence time or uneven agent distribution when the caps are fed intermittently.

[0015] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various changes and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
