Fibre dispersing machine

The utility model relates to a fibre dispersing machine. A motor 1 and a blower 3 are fastened on a frame 2, a hopper 5 is arranged above the frame 2, a feeding board 7 with a staircase-shaped surface is arranged below the hopper 5, and vibrating grids which block the air channel 9 of the blower is arranged below the front end of the feeding board 7. The motor 1 is connected with a speed regulating box, and the output end of the speed regulating box can respectively drive the blower 3, four connecting rods, and a cam which enables the vibrating grid to reciprocate vertical to the air channel 9. Fibre can be dispersed primarily on the staircase-shaped feeding board, falls onto a horizontal grid for a second dispersion and passes through a vertical grid for a third dispersion, so that the fibre blown into a blender is uniform but is not in a lump shape.
