The first latches and the second latches are arranged in a one-to-one correspondence, and the central axes of the corresponding first latches and the second latches coincide.

[0006] In the above-mentioned bottle cap sterilizing device, support protrusions are provided on the inner walls of the first clamping opening and the second clamping opening, so as to form a ventilation gap between the first clamping opening and the side wall of the bottle cap when the bottle cap is pushed to move.

[0007] In the above-mentioned bottle cap sterilization device, the dial wheel mechanism includes a first sterilization dial wheel and a second sterilization dial wheel respectively located on both sides of the guide rail mechanism; the sterilization mechanism includes a liquid collecting pipe for containing the sterilant and a plurality of sterilization nozzles connected to the liquid collecting pipe; sterilization nozzles are provided on the guide rail mechanisms on the sides of the first sterilization dial wheel and the second sterilization dial wheel.

[0008] In the above-mentioned bottle cap sterilization device, the sterilization nozzle on the side of the first sterilization wheel has an upper nozzle for spraying the top of the bottle cap and a first side nozzle for spraying the side of the bottle cap, and the sterilization nozzle on the side of the second sterilization wheel has a lower nozzle for spraying the bottom of the bottle cap and a second side nozzle for spraying the side of the bottle cap.

[0009] In the above-mentioned bottle cap sterilization device, the guide rail mechanism has a sterilization section corresponding to the sterilization mechanism, a drying section corresponding to the drying mechanism, and a cooling section corresponding to the cooling mechanism. The guide rail mechanism is provided with a fairing, which is wrapped around the outside of the sterilization section to form a sterilization chamber. The sterilization nozzle is installed on the fairing to spray sterilant into the sterilization chamber.

[0010] In the bottle cap sterilization device, the outer circumferences of the first sterilization dial wheel and the second sterilization dial wheel are both provided with flow disturbance holes, which vertically penetrate the first sterilization dial wheel and the second sterilization dial wheel to disturb the flow when passing through the sterilization chamber.

[0011] In the above-mentioned bottle cap sterilization device, the guide rail mechanism has a maintenance section connected between the sterilization section and the drying section, and the dial wheel mechanism also includes a drying dial wheel arranged on the side of the drying section and maintenance dial wheels arranged on both sides of the maintenance section, and the maintenance dial wheel is located between the second sterilization dial wheel and the drying dial wheel.

[0012] In the above-mentioned bottle cap sterilizing device, an extension cover is provided on the guide rail mechanism, and the extension cover is wrapped around the outside of the maintaining section to enclose a maintaining cavity communicated with the sterilization cavity.

[0013] In the above-mentioned bottle cap sterilizing device, the drying mechanism includes hot air pipes located at the upper and lower ends of the drying section and multiple hot air outlets connected to the hot air pipes, and the hot air outlets are aligned with the upper, lower and side parts of the guide rail mechanism respectively.

[0014] The beneficial effects of the present invention are:

[0015] A bottle cap sterilizing device includes a housing, within which are disposed a horizontally extending guide rail mechanism, a dial mechanism disposed on the side of the guide rail mechanism, a sterilizing mechanism for sterilizing the bottle caps, a drying mechanism for drying the bottle caps, and a cooling mechanism for cooling the bottle caps. The dial mechanism has a vertically disposed rotating shaft to drive the bottle caps to be transported horizontally on the guide rail mechanism. The guide rail mechanism includes upper and lower guide rails for transporting bottle caps of different sizes, with the upper guide rail located directly above the lower guide rail. This technical solution has the following technical effects:

[0016] The present invention arranges the rotating shaft of the thumbwheel mechanism vertically so that when the thumbwheel mechanism rotates around the rotating shaft, the outer peripheral side of the thumbwheel mechanism can push the bottle caps to slide horizontally on the guide rail mechanism and perform operations such as sterilization, drying and cooling. The horizontally extended guide rail mechanism can effectively prevent the bottle caps from shaking in the vertical direction during the transmission process, and the transmission is more stable. The guide rail mechanism is arranged into a horizontally extended lower guide rail and an upper guide rail located directly above the lower guide rail, and the upper guide rail and the lower guide rail are respectively used to transmit bottle caps of different sizes, so that the bottle cap sterilizing device can transmit and sterilize bottle caps of different sizes. When the bottle caps need to be sterilized in batches, the staff only needs to select the upper guide rail or the lower guide rail according to the size of the bottle caps, and then transmit them. There is no need to replace the guide rail or adjust the size of the guide rail. The bottle cap sterilizing device can transmit and sterilize bottle caps of different sizes, which makes the application range of the bottle cap sterilizing device wider and improves production efficiency.

[0017] The dial mechanism includes a coaxially arranged upper dial and a lower dial. The outer peripheral side of the upper dial is provided with a plurality of first bayonet holes for pushing the bottle cap to be transported on the upper guide rail, and the outer peripheral side of the lower dial is provided with a plurality of second bayonet holes for pushing the bottle cap to be transported on the lower guide rail. The first bayonet holes and the second bayonet holes are arranged in a one-to-one correspondence, and the central axes of the corresponding first bayonet holes and the second bayonet holes coincide, which facilitates rapid alignment of the upper dial and the lower dial during installation and reduces the difficulty of production and processing. At the same time, the coaxial arrangement of the first bayonet holes and the second bayonet holes can ensure smooth transmission of the bottle cap on the guide rail mechanism and prevent the bottle cap from getting stuck during transmission.

[0018] Support protrusions are provided on the inner walls of the first and second bayonet holes to form a ventilation gap between the bottle cap and the side wall when the bottle cap is pushed to move, so as to ensure that the sterilizer can be fully sprayed to various positions of the bottle cap through the ventilation gap during sterilization, avoiding the formation of sterilization dead corners and ensuring the sterilization effect.

[0019] The wheel mechanism includes a first sterilization wheel and a second sterilization wheel, respectively, located on either side of the guide mechanism. The sterilization mechanism includes a liquid collection pipe for containing sterilant and multiple sterilization nozzles connected to the liquid collection pipe. Sterilization nozzles are installed on the guide mechanisms on the sides of the first and second sterilization wheels. The sterilization nozzles are installed on the guide mechanisms on the sides of the first sterilization wheel and the second sterilization wheel, so that as the bottle caps pass through the first and second sterilization wheels in sequence, they are sprayed with sterilant once, thereby enhancing the sterilization effect of the bottle caps.

[0020] The sterilization nozzle on the side of the first sterilization dial wheel has an upper nozzle for spraying the top of the bottle cap and a first side nozzle for spraying the side of the bottle cap. The sterilization nozzle on the side of the second sterilization dial wheel has a lower nozzle for spraying the bottom of the bottle cap and a second side nozzle for spraying the side of the bottle cap. When the bottle cap passes through the first sterilization dial wheel, the upper nozzle and the first side nozzle can spray the sterilant on the top and left side of the bottle cap. When the bottle cap passes through the second sterilization dial wheel, the lower nozzle and the second side nozzle can spray the sterilant on the bottom and right side of the bottle cap. The combination of the upper nozzle, the first side nozzle, the lower nozzle and the second side nozzle makes the spraying of the sterilant on the bottle cap more uniform, and the sterilization of the bottle cap is more comprehensive and reliable.

[0021] The guide rail mechanism includes a sterilization section corresponding to the sterilization mechanism, a drying section corresponding to the drying mechanism, and a cooling section corresponding to the cooling mechanism. A fairing is provided on the guide rail mechanism, which wraps around the outside of the sterilization section to form a sterilization chamber. A sterilization nozzle is installed on the fairing to spray sterilant into the sterilization chamber. The fairing can concentrate the sterilant sprayed from the sterilization nozzle, preventing the aerosol formed by the sterilant from quickly escaping outward, thereby increasing the sterilant concentration in the sterilization chamber and achieving a better sterilization effect on bottle caps passing through the sterilization chamber. At the same time, the fairing can reduce the concentration of the sterilant and make it easier to control the spray temperature of the sterilant, ensuring that the sterilant maintains a good sterilization state.

[0022] The outer circumference of each of the first and second sterilization dial wheels is provided with a flow disturbance hole. The flow disturbance hole vertically penetrates the first and second sterilization dial wheels to disturb the flow when passing through the sterilization chamber. When the outer circumference of the first sterilization dial wheel (or the second sterilization dial wheel) extends into the sterilization chamber and pushes the bottle cap to move on the guide rail mechanism, the flow disturbance hole can disturb the flow in the sterilization chamber, helping the aerosol formed by the sterilizer to move within the sterilization chamber and adhere to the bottle cap, thereby improving the sterilization effect.

[0023] The guide rail mechanism includes a maintenance section connected between the sterilization section and the drying section. The thumbwheel mechanism also includes a drying thumbwheel located on the side of the drying section and maintenance thumbwheels located on both sides of the maintenance section, with the maintenance thumbwheels located between the second sterilization thumbwheel and the drying thumbwheel. After the bottle caps are sprayed with sterilizer in the sterilization section, they pass through the maintenance section before entering the drying section. This ensures that the sterilizer sprayed on the bottle caps can adhere to the bottle caps for a sufficient time to fully sterilize them before drying, thereby ensuring the sterilization effect of the bottle caps.

[0024] An extension cover is provided on the guide rail mechanism, which is wrapped around the outside of the maintaining section to form a maintaining cavity connected to the sterilization cavity. The extension cover extends the length of the sterilization cavity, increases the concentration of the bactericidal agent in the surrounding space when the bottle cap passes through the extension section, and helps to maintain the sterilization effect of the bactericidal agent on the bottle cap.

[0025] The drying mechanism includes a hot air pipe located at the upper and lower ends of the drying section and a plurality of hot air outlets connected to the hot air pipe. The hot air outlets are respectively aligned with the upper, lower and side parts of the guide rail mechanism, so that when the bottle caps pass through the drying section, the hot air outlets of the drying mechanism can simultaneously aim at the upper, lower and side parts of the bottle caps to blow hot air for rapid drying, with good drying effect, ensuring that the bottle caps entering the cooling section have been thoroughly dried.

The rotating shaft of the dial wheel mechanism is vertically arranged to drive the bottle caps to be horizontally transported on the guide rail mechanism. The guide rail mechanism includes an upper guide rail and a lower guide rail for transporting bottle caps of different sizes, and the upper guide rail is located directly above the lower guide rail. The present invention arranges the rotating shaft of the thumbwheel mechanism vertically so that when the thumbwheel mechanism rotates around the rotating shaft, the outer peripheral side of the thumbwheel mechanism can push the bottle caps to slide horizontally on the guide rail mechanism and perform operations such as sterilization, drying and cooling.

The guide rail mechanism is arranged into a horizontally extended lower guide rail and an upper guide rail located directly above the lower guide rail, and the upper guide rail and the lower guide rail are respectively used to transmit bottle caps of different sizes, so that the bottle cap sterilizing device can transmit and sterilize bottle caps of different sizes. When the bottle caps need to be sterilized in batches, the staff only needs to select the upper guide rail or the lower guide rail according to the size of the bottle caps, and then transmit them. There is no need to replace the guide rail or adjust the size of the guide rail. The bottle cap sterilizing device can transmit and sterilize bottle caps of different sizes, which makes the application range of the bottle cap sterilizing device wider and improves production efficiency.

[0045] Example:

[0046] A bottle cap sterilizing device, such as Figures 1 to 5As shown, it includes a housing, in which a guide rail mechanism 100, a dial mechanism 200, a sterilization mechanism 300, a drying mechanism 400, and a cooling mechanism 500 are arranged. The guide rail mechanism 100 extends horizontally for transporting bottle caps. The dial mechanism 200 is arranged on the side of the guide rail mechanism 100 for pushing the bottle caps to be transported on the guide rail mechanism 100. The sterilization mechanism 300 is used to spray a sterilizer on the bottle caps for sterilization. The drying mechanism 400 is used to dry the sterilized bottle caps. The cooling mechanism 500 is used to cool the dried bottle caps for subsequent operations. The rotating shaft of the dial mechanism 200 is vertically arranged, so that when the dial mechanism 200 rotates around the rotating shaft, the outer peripheral side of the dial mechanism 200 can push the bottle caps to be transported horizontally on the guide rail mechanism 100 for sterilization, drying, cooling and other operations. The horizontally extended guide rail mechanism 100 can effectively prevent the bottle caps from shaking in the vertical direction during transportation, making the transportation more stable. The guide rail mechanism 100 includes an upper guide rail 150 and a lower guide rail 160 extending horizontally. The upper guide rail 150 is located directly above the lower guide rail 160. The upper guide rail 150 and the lower guide rail 160 are respectively used to transport bottle caps of different sizes. When the bottle caps need to be sterilized in batches, the staff only needs to select the upper guide rail 150 or the lower guide rail 160 according to the size of the bottle caps, and then transport them. There is no need to replace the guide rails or adjust the size of the guide rails. The bottle cap sterilizing device can transport and sterilize bottle caps of different sizes, which makes the bottle cap sterilizing device have a wider range of applications and improves production efficiency.

[0047] like Figure 3 As shown, the dial mechanism 200 includes an upper dial 210 and a lower dial 220. The upper dial 210 and the lower dial 220 are coaxially arranged. A plurality of first bayonet holes 211 are evenly spaced on the outer periphery of the upper dial 210. When the upper dial 210 rotates, the first bayonet holes 211 are used to push the bottle caps to be transported on the upper guide rail 150. A plurality of second bayonet holes 221 are evenly spaced on the outer periphery of the lower dial 220. When the lower dial 220 rotates, the second bayonet holes 221 are used to push the bottle caps to be transported on the lower guide rail 160. The number of the first bayonet 211 and the second bayonet 221 on the coaxially arranged upper dial 210 and the lower dial 220 are the same and correspond one to one. The central axes of the two corresponding first bayonet 211 and second bayonet 221 coincide with each other, which facilitates the quick alignment of the upper dial 210 and the lower dial 220 during installation and reduces the difficulty of production and processing. At the same time, the coaxial arrangement of the first bayonet 211 and the second bayonet 221 can ensure the smooth transmission of the bottle cap on the guide rail mechanism 100 and prevent the bottle cap from getting stuck during the transmission process. Preferably, as Figure 4As shown, support protrusions 212 are provided on the inner walls of the first bayonet 211 and the second bayonet 221. When the first bayonet 211 (or the second bayonet 221) pushes the bottle cap to move, a ventilation gap is formed between the outer wall of the bottle cap and the inner wall of the first bayonet 211 (or the second bayonet 221) to ensure that the sterilizer can be fully sprayed to various positions of the bottle cap through the ventilation gap during sterilization, avoiding the formation of sterilization dead corners and ensuring the sterilization effect.

[0048] like Figure 3 As shown, in this embodiment, the dial wheel mechanism 200 includes a first sterilization dial wheel 231 and a second sterilization dial wheel 240 for pushing the bottle cap to be transported on the guide rail mechanism 100. The first sterilization dial wheel 231 and the second sterilization dial wheel 240 are respectively located on both sides of the guide rail mechanism 100. During the process of transporting the bottle cap on the guide rail mechanism 100, it first passes through the first sterilization dial wheel 231 and then passes through the second sterilization dial wheel 240. The sterilization mechanism 300 includes a liquid collection pipe 310 and multiple sterilization nozzles 320. The liquid collection pipe 310 is used to contain sterilizer. The sterilization nozzles 320 are connected to the liquid collection pipe 310 to spray the sterilizer in the liquid collection pipe 310 onto the bottle cap. Sterilization nozzles 320 are provided on the guide rail mechanism 100 on the side of the first sterilization dial wheel 231 and the guide rail mechanism 100 on the side of the second sterilization dial wheel 240, so that when the bottle cap passes through the first sterilization dial wheel 231 and the second sterilization dial wheel 240 in sequence, the sterilizer is sprayed once respectively, thereby enhancing the sterilization effect of the bottle cap. The sterilization nozzle 320 on the side of the first sterilization wheel 231 has an upper nozzle 321 and a first side nozzle 322. The upper nozzle 321 is used to spray the top of the bottle cap, and the first side nozzle 322 is used to spray the side of the bottle cap; the sterilization nozzle 320 on the side of the second sterilization wheel 240 has a lower nozzle 323 and a second side nozzle 324. The lower nozzle 323 is used to spray the bottom of the bottle cap, and the second side nozzle 324 is used to spray the side of the bottle cap.

[0049] Preferably, the first side nozzle 322 is arranged toward the central axis of the first sterilization dial wheel 231, and the second side nozzle 324 is arranged toward the central axis of the second sterilization dial wheel 240, and the spraying directions of the first side nozzle 322 and the second side nozzle 324 are opposite. When the bottle cap passes through the first sterilization dial wheel 231, the upper nozzle 321 and the first side nozzle 322 can spray the sterilant on the top and left side of the bottle cap. When the bottle cap passes through the second sterilization dial wheel 240, the lower nozzle 323 and the second side nozzle 324 can spray the sterilant on the bottom and right side of the bottle cap. Through the combination of the upper nozzle 321, the first side nozzle 322, the lower nozzle 323 and the second side nozzle 324, the spraying of the sterilant on the bottle cap is more uniform, and the sterilization of the bottle cap is more comprehensive and reliable.

[0050] In this embodiment, the guide rail mechanism 100 has a sterilization section 110 corresponding to the sterilization mechanism 300, a drying section 120 corresponding to the drying mechanism 400, and a cooling section 140 corresponding to the cooling mechanism 500. A fairing 111 is provided on the guide rail mechanism 100. The fairing 111 is wrapped around the outside of the sterilization section 110 to form a sterilization chamber that wraps the guide rail mechanism 100. The sterilization nozzle 320 is passed through the fairing 111 to spray sterilizer into the sterilization chamber. By providing the fairing 111, the sterilizer sprayed by the sterilization nozzle 320 can be gathered to prevent the aerosol formed by the sterilizer from escaping quickly to the outside, thereby increasing the concentration of the sterilizer in the sterilization chamber and achieving a better sterilization effect on the bottle caps passing through the sterilization chamber. At the same time, the provision of the fairing 111 can reduce the concentration of the sprayed sterilizer, and also make it easier to control the spray temperature of the sterilizer, thereby ensuring that the sterilizer maintains a better sterilization state.

[0051] like Figure 4 As shown, in this embodiment, preferably, spoiler holes 231 are provided on the outer peripheral sides of the upper dial 210 and the lower dial 220 of the first sterilization dial wheel 231 and the second sterilization dial wheel 240. The spoiler holes 231 vertically penetrate the first sterilization dial wheel 231 (or the second sterilization dial wheel 240) and are located between the two adjacent first bayonet holes 211 (or the second bayonet holes 221). When the outer peripheral side of the first sterilization dial wheel 231 (or the second sterilization dial wheel 240) extends into the sterilization cavity and pushes the bottle cap to move on the guide rail mechanism 100, the spoiler holes 231 between the two adjacent first bayonet holes 211 (or the second bayonet holes 221) can disturb the flow in the sterilization cavity to assist the aerosol formed by the sterilizer to move in the sterilization cavity and adhere to the bottle cap, thereby improving the sterilization effect.

[0052] like Figure 1 As shown, the drying mechanism 400 in this embodiment includes a hot air pipe 410, which is respectively located above and below the drying section 120. The hot air pipe 410 is provided with a plurality of air outlet pipes 420 surrounding a hot air outlet 421. The hot air outlet 421 is aligned with the upper part, the lower part and the side of the guide rail mechanism 100, respectively, so that when the bottle cap passes through the drying section 120, the hot air outlet 421 of the drying mechanism 400 can simultaneously blow hot air towards the upper part, the lower part and the side of the bottle cap for rapid drying, with good drying effect, ensuring that the bottle cap entering the cooling section 140 has been thoroughly dried.

[0053] The guide rail mechanism 100 in this embodiment further includes a maintaining section 130 connected between the sterilization section 110 and the drying section 120. The thumbwheel mechanism 200 further includes a drying thumbwheel 260 provided on the side of the drying section 120 and maintaining thumbwheels 250 provided on both sides of the maintaining section 130. The maintaining thumbwheels 250 are located between the second sterilization thumbwheel 240 and the drying thumbwheel 260 and are used to propel the bottle caps along the maintaining section 130. After the bottle caps are sprayed with sterilizer in the sterilization section 110, they first pass through the maintaining section 130 and then enter the drying section 120. This ensures that the sterilizer sprayed on the bottle caps can adhere to the bottle caps for a sufficient time to be fully sterilized before drying, thereby ensuring the sterilization effect of the bottle caps. Preferably, in this embodiment, an extension cover 131 is further provided on the guide rail mechanism 100. The extension cover 131 is wrapped around the outside of the maintaining section 130 to form a maintaining cavity connected to the sterilization cavity. The extension cover 131 extends the length of the sterilization cavity, thereby increasing the concentration of the sterilizer in the surrounding space when the bottle cap passes through the extension section, which helps to maintain the sterilization effect of the sterilizer on the bottle cap.

[0054] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
