A rotating shaft is located in the center of the cleaning and drying chamber, and several rotating seats are evenly arranged on the outer wall of the rotating shaft. A cleaning cylinder is detachably installed inside each rotating seat, and several cleaning holes are evenly arranged on the cleaning cylinder. The rotating shaft is connected to a rotating motor, and a water outlet pipe is located at the bottom of the cleaning and drying chamber. The water outlet pipe is connected to a hot water return pipe and a cold water return pipe, respectively. The hot water return pipe is connected to a hot water storage tank.

[0004] Existing technologies mainly clean rubber stoppers by rotating a drum. The mechanical rotation causes the rubber stoppers to squeeze and collide with each other, causing impurities on the stoppers to fall off. However, the rubber stoppers are also easily damaged during the agitation process, affecting their service life. Furthermore, after impurities are removed from the rubber stoppers, they remain in the cleaning solution, and the impurity content in the cleaning solution increases progressively, which also affects the cleaning effect.

[0005] Therefore, we propose a rubber stopper cleaning and drying machine. Utility Model Content

[0006] The present invention mainly addresses the technical problem of the increasing impurity content in the cleaning solution affecting the cleaning effect, and provides a rubber stopper cleaning and drying machine.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a rubber stopper cleaning and drying machine, comprising:

[0008] The outer shell and the top cover are hinged to the outer shell to form a sealed box structure. The cavity of the outer shell is provided with a removable inner liner. A hot air box and a fan are fixedly installed on both sides of the outer shell, respectively.

[0009] An aeration assembly is installed on the top cover wall to flush the rubber plug inside the inner liner. The aeration assembly includes an evacuation box, an outer cylinder, an inner cylinder, and guide bodies. The evacuation box is fixedly connected to the outer shell and has a cavity. The cavity of the evacuation box is connected to the exhaust port of the blower. The outer cylinder is fixedly connected to and communicates with the evacuation box. The inner cylinder is detachably connected to the outer cylinder. The wall of the inner cylinder has several filter holes. Several guide bodies are fixedly installed inside the cavity of the inner cylinder. There is a gap between the inner cylinder and the outer cylinder, and the gap communicates with the outside of the outer cylinder.

[0010] In a preferred embodiment of this utility model, the aeration assembly further includes a liquid inlet tank, and a plurality of liquid inlet tanks are formed on the wall of the outer cylinder, which are connected to the outside of the outer cylinder at intervals through the liquid inlet tanks.

[0011] In a preferred embodiment of this utility model, both the outer cylinder and the inner cylinder are circular tube structures, the inner diameter of the outer cylinder is larger than the outer diameter of the inner cylinder, and the inner cylinder is inserted into the cavity of the outer cylinder.

[0012] In a preferred embodiment of this utility model, the liquid inlet groove is formed on the circumferential surface of the outer cylinder, the length of the liquid inlet groove is less than the length of the outer cylinder, and a margin is left between the lower end of the liquid inlet groove and the bottom end of the outer cylinder.

[0013] In a preferred embodiment of this utility model, the guide body is fixedly installed on the inner wall of the inner cylinder, and the guide body forms a circular funnel structure. The smaller port of the upper guide body is inserted into the larger port of the lower guide body, and the two adjacent guide bodies do not contact each other and form a gap.

[0014] In a preferred embodiment of this utility model, the aeration assembly further includes an end head, which is fixedly connected to the inner cylinder.

[0016] This utility model provides a rubber stopper cleaning and drying machine. It has the following beneficial effects:

[0017] 1. This rubber stopper cleaning and drying machine uses a fan to send a high-speed airflow into an evacuation box and then into an outer cylinder. Several outer cylinders can be installed at the bottom of the evacuation box. The bundled airflow is guided by various guide bodies and discharged from the lower port of the inner cylinder, impacting the cleaning fluid and rubber stoppers. When the high-speed airflow passes through the inner cylinder chamber, a pressure difference is generated between the inside and outside of the inner cylinder due to the flow velocity. The flow velocity is higher and the pressure is lower in the inner cylinder, so the cleaning fluid outside the outer cylinder enters between the outer and inner cylinders. After being filtered through the filter holes on the inner cylinder wall, the cleaning fluid enters the inner cylinder, while impurities are stored in the gap between the outer and inner cylinders. While cleaning the rubber stoppers, it can collect and store impurities in the cleaning fluid, improving the cleaning effect on the rubber stoppers. The cleaning fluid can be kept clean, which is convenient for later recycling and reuse, resulting in better economic benefits and simplifying the subsequent cleaning fluid treatment steps.

[0018] 2. This rubber stopper cleaning and drying machine, by setting an inlet tank, allows the cleaning liquid outside the outer cylinder to enter the gap formed between the outer cylinder and the inner cylinder from the inlet tank. The design of the gradually narrowing opening of the inlet tank, that is, the smaller opening of the inlet tank faces the inner cylinder, can reduce the probability of impurities being discharged from the gap. The inlet tank, which is shorter than the outer cylinder, allows the outer cylinder to collect and store a certain amount of impurities, resulting in a better impurity collection effect.

[0019] 3. This rubber stopper cleaning and drying machine allows for the removal of the inner cylinder by connecting the end to the outer cylinder via a threaded connection, thereby facilitating the cleaning and maintenance of impurities collected in the crevices. Attached Figure Description

[0026] A rubber stopper cleaning and drying machine, such as Figure 1 and Figure 2 As shown, including:

[0027] The outer shell 10 and top cover 11 are hinged to the outer shell 10 to form a sealed box structure. A removable inner liner 14 is provided inside the cavity of the outer shell 10. A hot air box 12 and a fan 13 are fixedly installed on both sides of the outer shell 10, respectively. Specifically, the hot air box 12 contains a thermocouple and a fan. A delivery pipe is installed at the bottom of the hot air box 12, penetrating the side wall of the outer shell 10 and extending to the bottom of the inner liner 14. Hot air is introduced into the inner liner 14, flowing upwards to dry the rubber stopper inside. When cleaning the rubber stopper, cleaning fluid is injected into the cavity of the outer shell 10. The agent is used to blow air into the cavity of the outer shell 10 through the blower 13 to impact the liquid, causing the liquid to generate bubbles. The bursting of the bubbles can generate a certain impact, which loosens and removes the impurities on the rubber stopper, achieving a cleaning effect. A water pipe is installed on the wall of the outer shell 10, through which the cleaning fluid is added to and discharged from the cavity of the outer shell 10. The cleaning fluid needs to be discharged when drying the rubber stopper. A pad is fixedly installed at the bottom of the outer shell 10, and the inner liner 14 is placed on the pad, so that the bottom of the inner liner 14 is suspended from the bottom of the outer shell 10. A lifting lug is fixedly installed on the inner wall of the inner liner 14, and the rubber stopper can be loaded and unloaded by lifting the entire inner liner 14.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the aeration assembly, installed on the wall of the top cover 11, is used to flush the rubber plug inside the inner liner 14. The aeration assembly includes an evacuation box 20, an outer cylinder 21, an inner cylinder 22, and guide bodies 30. The evacuation box 20 is fixedly connected to the outer shell 10. The evacuation box 20 has a cavity, and the cavity of the evacuation box 20 is connected to the exhaust port of the blower 13. The outer cylinder 21 is fixedly connected to and communicates with the evacuation box 20. The inner cylinder 22 is detachably connected to the outer cylinder 21. The wall of the inner cylinder 22 has several filter holes. Several guide bodies 30 are fixedly installed inside the cavity of the inner cylinder 22. A gap is left between the inner cylinder 22 and the outer cylinder 21, and the gap communicates with the outside of the outer cylinder 21. Both the outer cylinder 21 and the inner cylinder 22 are circular tube structures. The inner diameter of the outer cylinder 21 is larger than the outer diameter of the inner cylinder 22. The inner cylinder 22 is inserted into the cavity of the outer cylinder 21. The guide body 30 is fixedly installed on the inner wall of the inner cylinder 22. The guide body 30 forms a circular funnel structure. The smaller port of the upper guide body 30 is inserted into the larger port of the lower guide body 30. The two adjacent guide bodies 30 do not contact each other and form a gap. The evacuation box 20 forms a hollow box structure. The upper end of the outer cylinder 21 penetrates the bottom of the evacuation box 20 and extends into the cavity of the evacuation box 20. A connecting pipe is fixedly installed on the top of the evacuation box 20. The connecting pipe is connected to the exhaust port of the fan 13 through a flexible hose.

[0029] In this scheme, a high-speed airflow is sent into the evacuation box 20 by the blower 13 and then into the outer cylinder 21. Several outer cylinders 21 can be set at the bottom of the evacuation box 20. The bundled airflow is guided by each guide body 30 and discharged from the lower port of the inner cylinder 22 to impact the cleaning fluid and rubber stopper. When the high-speed airflow passes through the inner cylinder 22, a pressure difference will be generated inside and outside the inner cylinder 22 due to the flow velocity. The flow velocity inside the inner cylinder 22 is high and the pressure is low. As a result, the cleaning fluid outside the outer cylinder 21 will enter between the outer cylinder 21 and the inner cylinder 22. After the cleaning fluid is filtered through the filter holes on the wall of the inner cylinder 22, the liquid enters the inner cylinder 22, while the impurities are stored in the gap between the outer cylinder 21 and the inner cylinder 22. While cleaning the rubber stopper, the impurities in the cleaning fluid can be collected and stored, which improves the cleaning effect on the rubber stopper. The cleaning fluid can be kept clean, which is convenient for later recycling and reuse, resulting in better economic benefits and simplifying the steps of post-processing the cleaning fluid.

[0030] like Figure 4 As shown, the aeration assembly also includes a liquid inlet trough 24. Several liquid inlet troughs 24 are opened on the wall of the outer cylinder 21, and are connected to the outside of the outer cylinder 21 at intervals through the liquid inlet troughs 24. The liquid inlet troughs 24 are opened on the circumferential surface of the outer cylinder 21. The length of the liquid inlet trough 24 is less than the length of the outer cylinder 21. There is a margin between the lower end of the liquid inlet trough 24 and the bottom end of the outer cylinder 21. By setting the liquid inlet trough 24, the cleaning liquid outside the outer cylinder 21 enters the gap formed by the outer cylinder 21 and the inner cylinder 22 from the liquid inlet trough 24. The design of the gradually narrowing opening of the liquid inlet trough 24, that is, the smaller opening of the liquid inlet trough 24 faces the inner cylinder 22, can reduce the probability of impurities being discharged from the gap. The liquid inlet trough 24, which is shorter than the outer cylinder 21, allows the outer cylinder 21 to collect and store a certain amount of impurities, and has a better collection effect on impurities.

[0031] like Figure 4 and Figure 5 As shown, the aeration assembly also includes an end head 23, which is fixedly connected to the inner cylinder 22. The outer wall of the outer cylinder 21 is provided with threads, and the inner wall surface of the end head 23 forms a tooth. The end head 23 is threadedly connected to the outer wall of the outer cylinder 21. By connecting the end head 23 to the outer cylinder 21, the inner cylinder 22 can be removed, thereby making it easier to clean the impurities collected in the gaps and simplifying the cleaning and maintenance steps.

[0032] The working principle of this utility model is as follows: The hot air box 12 is equipped with a thermocouple and a fan. A conveying pipe is installed at the bottom of the hot air box 12. The conveying pipe passes through the side wall of the outer shell 10 and extends to the bottom of the inner liner 14. Hot air is sent into the bottom of the inner liner 14. The hot air flows from bottom to top to dry the rubber stopper inside the inner liner 14. When cleaning the rubber stopper, a cleaning agent is injected into the cavity of the outer shell 10. The fan 13 sends air into the cavity of the outer shell 10 to impact the liquid, causing the liquid to generate bubbles. The bursting of the bubbles can generate a certain impact, causing the impurities on the rubber stopper to loosen and fall off, thus achieving the cleaning effect.

[0033] The blower 13 sends a high-speed airflow into the evacuation box 20 and then into the outer cylinder 21. Several outer cylinders 21 can be installed at the bottom of the evacuation box 20. The bundled airflow, guided by various guide bodies 30, exits from the lower port of the inner cylinder 22, discharging the impact cleaning fluid and rubber stopper. When the high-speed airflow passes through the inner cylinder 22, a pressure difference is created between the inside and outside of the inner cylinder 22 due to the flow velocity; the flow velocity inside the inner cylinder 22 is higher than the pressure. Consequently, the cleaning fluid outside the outer cylinder 21 enters between the outer cylinder 21 and the inner cylinder 22. The cleaning fluid passes through the inner cylinder... After filtration through the filter holes on the wall of cylinder 22, the liquid enters the inner cylinder 22, while impurities are stored in the gap between the outer cylinder 21 and the inner cylinder 22. While cleaning the rubber stopper, impurities in the cleaning fluid can be collected and stored. The inner cylinder 22 can be removed or installed by threaded connection between the end 23 and the outer cylinder 21. A ring plate is fixedly installed on the top of the outer cylinder 21. The inner diameter of the ring plate is smaller than the outer diameter of the inner cylinder 22, that is, the ring plate will abut against the upper end face of the inner cylinder to ensure that gas enters the cavity of the inner cylinder 22.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
