[0035] First, according to the width and thickness of the non-woven fabric, the operator makes a preset through the adjusting assembly. By rotating the adjusting threaded rod 8, the moving member 9 drives the mounting member 5 to slide along the adjusting groove of the transmission shaft 4, thereby adjusting the distance between the two trimming knives 6 to adapt to non-woven fabrics of different widths. At the same time, by using the adjusting bolt 11 and the adjusting member 10, the height of the transmission shaft 4 is adjusted to ensure the best position where the trimming knife 6 contacts the non-woven fabric and adapt to different thicknesses. In addition, through the cooperation of the adjusting bolt 22 and the spring 23 in the power assembly, the clamping force of the clamping member 21 on the non-woven fabric is adjusted to ensure an appropriate tension, avoid material deformation or tearing. The non-woven fabric is guided to one side guide member 3, and the clamping assembly starts to work. The driven member 20 in the auxiliary member 19 is driven by the power assembly to drive the clamping member 21 to apply pressure to the non-woven fabric, ensuring that the fabric is tightly attached to the guide member 3, creating a flat working surface for cutting, avoiding wrinkles and displacement. The driving motor 16 is started, and the power is transmitted to the transmission shaft 4 through the precise transmission system of the driving shaft 17, the hollow shaft 13, and the bevel gears 14 and 15, driving the two trimming knives 6 to rotate synchronously at high speed. As the non-woven fabric advances, the trimming knives 6 accurately cut off the excess edges to form neat edges.
