An auxiliary guide wheel 10 is fixedly connected to the lower surface of the filter cylinder 7. The auxiliary guide wheels 10 are arranged in a ring and abut against the bottom wall of the inner cavity of the washing tub 2. A first pulley 4 and a second pulley 5 are rotatably connected to the lower surface of the base 1. A transmission belt 6 is provided between the first pulley 4 and the second pulley 5. One end of the first pulley 4 is fixedly connected to the shaft end of the rotating shaft 3. A drive motor 8 and a reducer 9 are fixedly connected to the surface of the base 1. The power output end of the drive motor 8 is fixedly connected to the input end of the reducer 9, and the output end of the reducer 9 is fixedly connected to the shaft end of the second pulley 5. The auxiliary guide wheels 10 are in contact with the inner wall of the washing tub 2. The bottom wall of the chamber abuts against the filter cylinder 7, providing support and assisting in its rotation, ensuring the stability of the filter cylinder 7's rotation. During washing, the wool sweater is placed in the filter cylinder 7, while water, detergent, and shrinking agent are added to the washing tub 2. Then, the drive motor 8 is started, and the power is transmitted to the second pulley 5 via the reducer 9. Through the transmission belt 6, the first pulley 4 is rotated, which in turn causes the rotating shaft 3 connected to the first pulley 4 and the filter cylinder 7 to rotate, performing the washing and shrinking process. After shrinking is completed, the valve 23 is opened, and the wastewater is discharged into the external wastewater treatment system through the drain pipe 22. This integrates the functions of shrinking, dehydrating, and cleaning the floating lint from the inner wall of the filter cylinder 7 into one unit, avoiding the cumbersome operation of frequently transferring wool sweaters and using multiple devices in the traditional process, significantly improving production efficiency. The auxiliary guide wheel 10 enhances the stability of the filter cylinder 7 during rotation, reducing equipment wear and poor treatment results caused by the shaking of the filter cylinder 7. At the same time, the transmission structure, through the cooperation of the pulley and the reducer 9, ensures smooth power transmission and guarantees the stable operation of the equipment for a long time.

[0023] In this embodiment, a column 11 is fixedly connected to the surface of the base 1, a hinge 12 is fixedly connected to the side wall of the column 11, a fixing frame 13 is hinged to the inner side wall of the hinge 12, a first cylinder 14 is fixedly connected to the inner side wall of the fixing frame 13, an installation head 15 is fixedly connected to the movable end of the first cylinder 14, and a pressure plate 16 and a scraper 17 are detachably connected to the first cylinder 14 via the installation head 15. The pressure plate 16 is used to press out the moisture from the wool sweater, and the scraper 17 is used to scrape off the floating hair from the inner wall of the filter cartridge 7. A first connecting rod 18 is rotatably connected to the side wall of the column 11, a second connecting rod 19 is rotatably connected to one end of the first connecting rod 18, and one end of the second connecting rod 19 is rotatably connected to the surface of the fixing frame 13. A second cylinder 20 is fixedly connected to the surface of the column 11, a connector 21 is fixedly connected to the movable end of the second cylinder 20, and the inner side wall of the connector 21 is rotatably connected to one end of the first connecting rod 18. When it is necessary to remove moisture from the wool sweater, the second... Cylinder 20 pushes connector 21, causing first connecting rod 18 and second connecting rod 19 to rotate, causing fixed frame 13 and connected first cylinder 14 and pressure plate 16 to rotate and move to a suitable position. First cylinder 14 operates to push pressure plate 16 down on the wool sweater, squeezing out excess water. When removing floating hair from the inner wall of filter cylinder 7, the pressure plate 16 on mounting head 15 is replaced with scraper 17, and the above-mentioned action driven by second cylinder 20 is repeated, so that scraper 17 is close to the inner wall of filter cylinder 7. As filter cylinder 7 rotates, scraper 17 scrapes off the floating hair from the inner wall, realizing the floating hair treatment. Under the drive of first cylinder 14, pressure plate 16 can apply appropriate pressure to wool sweater, efficiently squeeze out water, shorten subsequent drying time, and reduce energy consumption. By using replaceable scraper 17 in conjunction with rotating filter cylinder 7, floating hair attached to the inner wall of filter cylinder 7 can be effectively and comprehensively scraped off, reducing the impact of floating hair on subsequent production processes and product quality.

[0024] The auxiliary guide wheel 10 abuts against the bottom wall of the inner cavity of the washing tub 2, providing support and assisting in the rotation of the filter cartridge 7, ensuring the stability of the filter cartridge 7's rotation. During washing, the wool sweater is placed in the filter cartridge 7, and water, detergent, and felting agent are added to the washing tub 2. Then, the drive motor 8 is started, and the power is transmitted to the second pulley 5 via the reducer 9. This drives the first pulley 4 to rotate via the transmission belt 6, thereby causing the rotating shaft 3 connected to the first pulley 4 and the filter cartridge 7 to rotate, performing the washing and felting process. After the felting is completed, the valve 23 is opened, and the wastewater is discharged into the external wastewater treatment system through the drain pipe 22. When it is necessary to remove moisture from the wool sweater, the second cylinder 20 pushes the connector 21, which drives the first connecting rod 18 and the second connecting rod 19 to rotate, causing the fixed frame 13 and the connected first cylinder 14 and pressure plate 16 to rotate and move to a suitable position. The first cylinder 14 operates to push the pressure plate 16 down to squeeze out excess water from the wool sweater. When removing floating hair from the inner wall of the filter cartridge 7, the pressure plate 16 on the mounting head 15 is replaced with a scraper 17, and the above-mentioned action driven by the second cylinder 20 is repeated, so that the scraper 17 is close to the inner wall of the filter cartridge 7. As the filter cartridge 7 rotates, the scraper 17 scrapes off the floating hair from the inner wall, thus achieving the floating hair treatment.

[0025] This application integrates the functions of wool sweater shrinking, dehydration, and cleaning of loose fibers from the inner wall of the filter cartridge 7 into one unit. This avoids the cumbersome operation of frequently transferring wool sweaters and using multiple devices in traditional processes, significantly improving production efficiency. The auxiliary guide wheel 10 enhances the stability of the filter cartridge 7 during rotation, reducing equipment wear and poor processing results caused by filter cartridge 7 shaking. At the same time, the transmission structure, through the pulley and reducer 9, ensures smooth power transmission and guarantees stable operation of the equipment for a long time. The pressure plate 16, driven by the first cylinder 14, can apply appropriate pressure to the wool sweater, efficiently squeezing out moisture, shortening subsequent drying time, and reducing energy consumption. Through the replaceable scraper 17 working in conjunction with the rotating filter cartridge 7, it can effectively and thoroughly scrape off the loose fibers adhering to the inner wall of the filter cartridge 7, reducing the impact of loose fibers on subsequent production processes and product quality.
