The water stains on the surface of the squeezing roller are diverted by the guide component one to prevent the water stains on the surface of the squeezing roller from flowing back into the non-woven fabric, thereby improving the squeezing effect. The water stains on the surface of the driven roller are diverted by the guide component two to prevent the water stains on the surface of the driven roller from flowing back into the non-woven fabric, thereby improving the squeezing effect. The non-woven fabric passes through the drying component one and the drying component two in turn, and the first drying treatment is achieved by the drying component one, and the second drying treatment is achieved by the drying component two, thereby improving the drying quality of the non-woven fabric.
