The power output end of the lifting motor 29 extends into the interior of the mounting base 35 and is equipped with a drive gear 34. The bottom of the screw 32 extends into the interior of the mounting base 35 and is equipped with a driven gear 33. A linkage gear 36 is provided between the gear and the driven gear 33. The interior of the lifting rod is provided with a threaded hole 37, and the screw 32 extends into the interior of the threaded hole 37 and is threadedly connected to it. Driven by the lifting motor 29, the lifting rod 10 moves up and down, thereby controlling the position of the cleaning net bucket 15 in the cleaning tank 4, making the cleaning process more flexible. The height of the cleaning net bucket 15 can be adjusted as needed to ensure the cleaning effect.

[0028] Further improvements, such as Figure 3 As shown: The bottom of the cleaning net bucket 15 is provided with a base plate 23 and the inside of the base plate 23 is provided with a fitting groove 24. The fitting groove 24 fits into the aeration plate 27. The design of the base plate 23 and the fitting groove 24 allows the cleaning net bucket 15 to be placed stably on the aeration plate 27, ensuring the effect of bubble cleaning.

[0029] Further improvements, such as Figure 3 As shown: The surface of the cleaning mesh bucket 15 and the interior of the base 23 are both provided with mesh holes of uniform size. The uniform mesh hole design ensures the uniform distribution of water flow during the cleaning process and improves the cleaning effect. The size of the mesh holes of different cleaning mesh buckets 15 can also be adjusted according to actual needs to adapt to rubber stoppers of different specifications.

[0030] Further improvements, such as Figure 1 As shown: The upper part of the machine body 1 is provided with a fixed seat 9 and the lifting rod 10 extends into the interior of the fixed seat 9 and is slidably connected to it. The design of the fixed seat 9 makes the lifting rod 10 more stable during the up and down movement, reduces shaking and deviation, and improves the accuracy and effect of cleaning.

[0031] Further improvements, such as Figure 1As shown: Sliding rods 11 are provided on both sides of the lifting rod 10, and the bottom of the sliding rods 11 extends into the installation space of the lifting mechanism 22. The top of the sliding rods 11 is connected to the support plate 12. The design of the sliding rods 11 further enhances the stability of the lifting mechanism 22 and ensures the smoothness of the cleaning net barrel 15 during the up and down movement.

[0032] Further improvements, such as Figure 1 As shown: The hoisting frame 13 is arranged in a triangular structure and is rotatably connected to the connecting cover 14. The triangular structure design makes the hoisting frame 13 more stable and able to withstand greater weight and torque, ensuring the safety of the cleaning net bucket 15 during the hoisting process.

[0033] Further improvements, such as Figure 5 As shown: A temperature sensor 39 and a liquid level sensor 38 are installed in the installation space of the lifting mechanism 22.

The sensors can monitor the temperature and liquid level changes in the cleaning tank 4 in real time, providing accurate data support for the control panel 3 and ensuring the controllability and stability of the cleaning process.

[0034] Working principle: Rubber plugs are added into the cleaning mesh tub 15 through the inlet, ensuring even distribution. The control valve of the inlet pipe 18 is activated via the control panel 3, directing cleaning water into the cleaning tank 4 until the water level reaches the predetermined height. The cleaning mesh tub 15 moves up and down within the cleaning tank 4 via the lifting mechanism 22, ensuring the rubber plugs in the tub are thoroughly and evenly rinsed. The cleaning water is discharged into the overflow tank 16 through the overflow hole 6 at the top of the partition 5 and then discharged through the overflow drain 17. Through physical rinsing, dirt and impurities on the surface of the rubber plugs are initially removed. When the water level reaches the specified height… Turn on the ultrasonic generator 8 and perform cleaning according to the specified time. The vibration waves generated by the ultrasonic waves create cavitation in the cleaning fluid, deeply cleaning the rubber stopper. The cleaning water flows out through the top overflow hole 6, carrying away the dirt and impurities removed. Ultrasonic cleaning can penetrate deep into the fine structure of the rubber stopper, effectively removing residues and improving the cleaning effect. After ultrasonic cleaning is completed, turn on the air compressor 25. Compressed air enters the aeration plate 27 at the bottom of the cleaning tank 4 through the purification booster pump 26. The aeration plate 27 forms bubbles to clean the rubber stopper. At the same time, fresh water enters from the bottom, and the cleaning water flows through... The top overflow hole 6 drains away residual dirt and impurities. Bubble cleaning further enhances the cleaning effect, using the bursting action of bubbles to perform a secondary cleaning of the rubber stopper, ensuring thorough cleaning. After cleaning, all control valves and power are turned off, and wastewater in the cleaning tank 4 is drained through drain pipe 19, preparing for the next cleaning. The equipment is equipped with an automatic recording system that records the operation process, time, date, clean air pressure, and operator information. The equipment operating system is equipped with an industrial IPC computer, which can record equipment operation data at any time, set different parameter formulas, batch reports, formula reports, alarm records, audit trails, remote services, etc. Records, reports, and statements can be read through MES or SCADA systems. The equipment can reduce manual input and control human contamination when cleaning rubber stoppers. The micro-jets and shock waves generated by the ultrasonic cavitation effect can penetrate into the tiny pores and complex curved surfaces of the rubber stopper, areas that are difficult to reach by traditional cleaning methods, thoroughly removing oil, particulate matter, and microbial residues. It has a strong ability to remove stubborn contaminants such as grease and gum, and the cleaning process does not rely on large amounts of chemical cleaning agents, reducing the risk of residue.
