[0029] In a specific embodiment, a non-woven fabric winding device is provided next to the non-woven fabric dyeing device. The non-woven fabric winding device rotates to drive two pressure rollers. The two pressure rollers rotate to drive the first rotating shaft and the second rotating shaft. When in use, the dye is transported to the liquid supply box 2 through the feed port 701, and the dye is transported to the dyeing box 1 through the pump 702 and the pipeline 703 of the liquid supply component. During the transportation process, the dye flow rate is controlled by the valve 704 and the flow meter 705. After the dye enters the dyeing box 1, the stirring component at the bottom of the dyeing box 1 stirs the dye; the non-woven fabric moves in the dyeing box 1 under the action of the winding device. Since the non-woven fabric is wound around the outside of the conveying roller 4, the non-woven fabric can move below the dye liquid surface for dyeing; then the dyed non-woven fabric moves between the two pressure rollers 102, and the two pressure rollers 102 perform preliminary squeezing on the non-woven fabric to reduce excess dye and moisture on the non-woven fabric. Then, since the winding device drives the non-woven fabric to move, the non-woven fabric passes through the two When the pressure roller 102 is turned, it drives the two pressure rollers 102 to rotate in opposite directions. Since the first rotating shaft 101 and the second rotating shaft 501 at the bottom are respectively fixed with first bevel gears 602, the two first bevel gears 602 are driven by the second bevel gear 603, causing the two first bevel gears 602 to rotate in opposite directions, thereby driving the second rotating shaft 501 to rotate in opposite directions with the first rotating shaft 101. At the same time, since the two first rotating shafts 101 are driven by the transmission gear 601, they drive the two first rotating shafts 101 to move towards each other, causing the two scrapers 503 to rotate in opposite directions. After the two scrapers 503 abut the non-woven fabric, the mutual thrust between the two is greater than the friction between the connecting frame 502 and the second rotating shaft 501, causing the connecting frame 502 and the second rotating shaft 501 to rotate relative to each other, so that the scrapers 503 are always stable on the upper and lower sides of the non-woven fabric, further scraping off excess dye and moisture on the non-woven fabric, and returning the dye and moisture to the dyeing box 1. The fabric then moves to the drying box 3 for drying.
