The surfaces of the flexible wiping sheets 432 on both sides are symmetrical and fit with the surface of the non-woven fabric. As the non-woven fabric moves, the debris remaining on the surface of the non-woven fabric is wiped. The pressing piece 34 pushes the force-bearing paddle 45, and the slider 42 can slide on the U-shaped frame 41.The first processing device 43 is made to move closer to the second processing device 44 as a whole, so that the surface of the flexible wiping sheet 432 is closely attached to the surface of the non-woven fabric, which promotes the cleaning of the non-woven fabric. At the same time, the bottom of the arc scraper 433 is rotatably connected to the top of the connecting rod 431, and under the elastic support of the butterfly spring 434, the top of the arc scraper 433 on both sides symmetrically scrapes the non-woven fabric flat, which is not easy to wrinkle. The interaction between the structures is used and the structures are cleverly connected together, which is safe and reliable, realizes multiple functions, and improves the performance.
