The filament paving device further comprises a driving device, the movable plate 2 is connected with the output end of the driving device, and the movable plate 2 swings left and right relative to the fixed plate 3 under the driving of the driving device. Specifically, drive arrangement includes motor 5 that vertical draft tube 1 axial set up, connects in the pivot 6 between motor 5 and movable plate 2, and is specific, and 6 one end of pivot are passed through the shaft coupling and are connected with 5 output shaft of motor, and the 6 other ends of pivot are passed through universal joint 7 and are connected with movable plate 2. When the device is used, the motor 5 drives the rotating shaft 6 to rotate forward and backward to realize the left-right swing of the movable plate 2, the movable plate 2 can adjust the inclination angle between the movable plate and the fixed plate 3 through the universal joint 7, and the device is simple in structure and convenient to operate.

The filament spreading device further comprises a frame 8, the motor 5 is fixedly arranged on the frame 8, and the middle of the rotating shaft 6 is installed on the frame 8 through a bearing 9.

When the device is used, tows coming out of the drawing pipe 1 are firstly sprayed on the movable plate 2 and then are refracted on the fixed plate 3 through the movable plate 2 and then fall on the net curtain. In the process, the driving device drives the movable plate 2 to swing, so that the fibers falling on the net curtain can be uniform in unit width.

Compared with the prior art, the embodiment has the beneficial effects that:

the filament spreading device of the embodiment can enable the fibers falling on the net curtain to be uniform by firstly spraying the filament bundles coming out of the drafting tube 1 onto the movable plate 2, then refracting the filament bundles to the fixed plate 3 through the movable plate 2, and then falling on the net curtain of the net forming machine 4.
