Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cotton swab processing, and more specifically, to a sterilization device for cotton swab production. Background Technique
[0002] A cotton swab, also known as a swab stick, is a small wooden stick or plastic stick slightly larger than a matchstick wrapped with a little disinfected cotton, mainly used for applying medicine and absorbing pus and blood in medical treatment. There are many types of cotton swabs, including dust-free swab sticks, clean cotton swabs, medical cotton swabs, and instant-apply cotton swabs. Currently, medical cotton swabs generally come into direct contact with patients' wounds, so they need to be strictly disinfected and sterilized before use.
[0003] The two most commonly used existing cotton swab disinfection and sterilization methods are roughly divided into two types. One is ultraviolet lamp sterilization, but the sterilization effect of this method generally does not meet the usage requirements of medical cotton swabs. The other is high-temperature steam sterilization, which uses a cotton swab conveying chain to convey cotton swabs in a production line and performs the sterilization process during transportation. This method has a good disinfection and sterilization effect, but the cotton swabs cannot be effectively turned during the subsequent drying process, resulting in insufficient drying and the need to improve the sterilization effect of the cotton swabs.
[0004] Publication No. CN216963084U proposed a high-efficiency sterilization device for medical cotton swabs. This device can fully disinfect cotton swabs during the conveying process, meet medical requirements, improve product quality, and enable continuous production, thus improving production efficiency. However, the cotton swabs cannot be turned during the drying process of this device, and the drying effect needs to be improved. Summary of the Utility Model

[0016] Furthermore, the driving assembly includes a mounting rod, a rotating shaft and a servo motor. The mounting rods are symmetrically arranged on both sides of the drying box. A rotating shaft is rotatably connected between the two mounting rods. A sprocket is arranged on the rotating shaft and one end of the rotating shaft is connected to a servo motor fixed to one of the mounting rods.
[0017] The above solution uses a driving component to keep the frequency of the chain wheel consistent with that of the conveyor chain, thereby realizing the assembly line transfer of the cotton swabs into the drying box.
[0018] Furthermore, the sterilization assembly includes a sterilization main pipe, a sterilization branch pipe and a steam boiler. The sterilization main pipe is arranged in the sterilization chamber, a plurality of sterilization branch pipes are arranged on the sterilization main pipe, and the sterilization main pipe is connected to the steam boiler arranged outside the sterilization chamber.
[0019] The above scheme realizes the efficient and sufficient disinfection and sterilization process of the cotton swab through the sterilization component.
[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0021] Compared with the prior art, this device can sterilize cotton swabs sufficiently and efficiently by delivering high-temperature steam into the sterilization chamber through the sterilization component and cooperating with the conveying chain. The sterilization effect is good, and then it is automatically transferred to the drying box through the chain wheel for uniform drying by turning the materials. After drying, it is automatically discharged through the conveyor belt, which is suitable for assembly line operation and has high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] For further refinement of the solution of the embodiment of the present utility model, as Figure 1 and Figure 2 shown, the drying component includes a hot air blower 34, a main drying pipe 35, and drying branch pipes 36. A hot air blower 34 and a main drying pipe 35 are arranged on the drying box 3. The hot air blower 34 is communicated with the main drying pipe 35. A plurality of drying branch pipes 36 inside the drying box 3 are arranged on the main drying pipe 35. The drying branch pipes 36 and the conveying plates 32 are distributed in a staggered manner.
[0029] For further refinement of the solution of the embodiment of the present utility model, as Figure 1 shown, the driving component includes a mounting rod 21, a rotating shaft, and a servo motor 22.

[0032] The working process of the present utility model:
[0033] First, the cotton swabs are conveyed in a production line through the cotton swab conveying chain 1. Then, the cotton swabs sequentially enter the sterilization chamber 11 for the high-temperature steam sterilization process. At this time, the controller controls the steam boiler 14 to work to complete the full and multi-point introduction of high-temperature steam into the sterilization chamber 11. Since the layout distance of the sterilization chamber 11 is relatively long, it can ensure the full disinfection and sterilization of the cotton swabs. After sterilization, the cotton swabs are conveyed to the end of the conveying chain. At this time, the controller controls the servo motor 22 to work and rotate counterclockwise at a constant speed. At this time, the rotation speed of the chain wheel 2 is consistent with the conveying speed of the conveying chain. Then, the cotton swabs can be sequentially transferred onto the chain wheel 2 and move with the chain wheel 2 and finally be injected into the drying box 3 from the feeding port 31. At this time, the baffle 38 can prevent the cotton swabs from falling into the outer area on the left side of the feeding port 31. The cotton swabs falling into the drying box 3 are transferred through multiple conveying plates 32 in sequence. At this time, the controller controls the hot air blower 34 to work and then continuously introduce hot air into the drying box 3 through the drying branch pipe 36. At this time, the cotton swabs can be fully contacted with the hot air during the process of rolling on the conveying plate 32 to achieve drying, and the multiple conveying plates 32 effectively extend the residence time of the cotton swabs in the drying box 3. Finally, the cotton swabs sequentially fall onto the conveyor belt 33 and move along the conveyor belt 33 to the outside of the drying box 3, and then the production line sterilization process of the cotton swabs can be completed;
[0034] Compared with the prior art, the device of the present invention can sterilize the cotton swabs sufficiently and efficiently through high-temperature steam in cooperation with the conveying chain, with good sterilization effect, and then automatically transfer to the drying box 3 for uniform drying by turning the materials. After drying, it automatically discharges the materials, is suitable for production line operation and has high efficiency.
[0035] In some embodiments, as Figure 2 shown, a heating plate 37 is arranged at the bottom of the conveying plate 32 and a number of micropores are formed on the conveying plate 32. The heating plate 37 is electrically connected to the controller; for the further optimization of the above embodiment solution, a vibration motor 5 is arranged on the drying box 3; in this embodiment, the heating plate 37 in cooperation with the drying assembly can further shorten the time required for drying the cotton swabs. At the same time, the hot air can move upward along the micropores, and cooperate with the vibration motor 5 to prevent the cotton swabs from accumulating on the conveying plate 32, and the blanking is smooth.
