[0045] The clamping rods 407 connected to the swinging member 405 are staggered up and down, and are arranged left and right in the horizontal position with a certain gap, which is used to clamp the fabric body. The elliptical block 406 is driven by the motor to rotate. During the continuous rotation of the elliptical block 406, one end of the swinging member 405 is cyclically squeezed and reset.

This elastic potential energy is used as the reset power of the swinging member 405. With the movement of the swinging member 405, the clamping rod 407 connected to the other end of the swinging member 405 is driven to swing up and down with the connecting axis of the mounting frame 401 as the center.

[0046] A first diverter 202 is provided on the top of the separation box 201 in the moisture separation component 2, and a second diverter 302 is provided on the top of the separation box 201 in the solid impurity separation component 3; it also includes a fan 8, the air inlet of the fan 8 is connected to the second diverter 302, and the air outlet of the fan 8 is connected to the dust removal box 5, and the dust removal box 5 is connected to the first diverter 202.

Under the action of the motor, the swing directions of every two adjacent swinging members 405 are opposite. When one of the swinging members 405 is in the initial position, the adjacent swinging members 405 are in the position of the maximum swing angle; the fan 8 is started to form a wind circulation, and the moisture and impurities are separated while the conveying roller 7 conveys the fabric.
