[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] Working principle: When in use, the device is first installed inside the cotton opener through the support base 28 and the screw hole 29, and the scraper 4 is aligned with the roller, and at the same time, it is ensured that the spacing of the scraper 4 is adapted to the spacing of the lever. When the cotton opener completes the cotton cleaning work of the cotton block, the servo motor 10 can be started, and the servo motor 10 drives the active bevel gear 12 to rotate through the transmission shaft 11, and the active bevel gear 12 drives the driven bevel gear 9 meshing with it to rotate, and the driven bevel gear 9 drives the lifting block 6 threadedly connected to it to move through the threaded rod 8, so that the elastic component 5 moves downward until the scraper 4 is close to the lever. At this time, the rotating roller will cause the lever to pass through the scraper 4. , so that the cotton balls wrapped above it can be scraped off. When the cotton balls on some of the levers are difficult to clean, they will resist the scraper 4. When the scraper 4 is unable to cut off the cotton balls due to the force, it will actively contract upward to squeeze the second spring 505 and the first spring 504, so that the cotton balls can pass through, and continue to be cleaned at the next contact. After multiple scrapings, the cotton balls can be cleaned up, and the air pump 20 can be started at the same time. The air pump 20 draws air into the cotton suction tube 17 through the air inlet pipe 21, the telescopic hose 22 and the L-shaped tube 19. The cotton suction tube 17 then draws air downward through the expansion pipe 18 to collect the cotton balls, and transports them to the collection box 23 for collection, which is convenient for subsequent centralized processing.
