The above method simply composites a nanofiber layer on a micron fiber web, which is prone to unevenness, and there are voids at the interlayer connection parts, resulting in easy peeling during use. At the same time, the existing cross-laying structure cannot be cross-laid, which is not conducive to actual use, and the cross-laying structure only uses multiple sets of driving structures, resulting in high energy consumption.

[0040] The external fan pumps the air in the dust collection hood 21 through the air extraction pipe 25, the Z-shaped pipe 23, the C-shaped pipe 26, the air duct 22 and the straight pipe 28. At the same time, the C-shaped pipe 26 rotates with the air duct 22 and the Z-shaped pipe 23. The C-shaped pipe 26 rotates following the rotating shaft of the first conveyor belt 35 away from the carding machine and the rotating shaft at the upper end of the third conveyor belt 324. The connection part of the Z-shaped pipe 23 and the air extraction pipe 25 rotates following the rotating shaft of the first conveyor belt 35 close to the carding machine, realizing that the dust collection hood 21 moves following the second conveyor belt 36 and the third conveyor belt 324, which is beneficial to the dust collection hood 21 to follow for dust collection. The follow-up dust collection assembly 2 sucks the flying flocs following the placement assembly 3, which is beneficial to the collection of flying flocs and avoids the pollution of the processing environment by flying flocs.
