Simultaneously, a second motor in front rotates a fourth pulley, which in turn drives a second rotating shaft to rotate, thereby causing a take-up roller to rotate synchronously to take up the slit nonwoven fabric, achieving integrated slitting and take-up, which is more efficient and practical.

[0017] 3. This utility model allows the first fastening nut to be rotated clockwise to move to the left and counterclockwise to move to the right, making it convenient and flexible to adjust the position of the cutter holder on the upper threaded rod. This allows for easy adjustment of the distance between two adjacent sets of cutter holders. In addition, the upper pressure plate facilitates the stable flattening of the nonwoven fabric surface, resulting in more neat and stable cutting by the middle cutter.

[0018] 4. This utility model allows for flexible adjustment of the position of the lower moving seat on the lower threaded rod by rotating the second fastening nut clockwise to move it to the left and counterclockwise to move it to the right. This enables flexible adjustment of the distance between two adjacent sets of lower moving seats.
