Double-feeding double-helical-tooth carding wool yarn spraying machine

The invention discloses a double-feeding double-helical-tooth carding wool yarn spraying machine. The double-feeding double-helical-tooth carding wool yarn spraying machine comprises an input device for feeding fiber raw materials, a carding device for carding fibers, a transmission device for driving the carding device to operate and an output device connected with the carding device and used fortwisting and outputting the fibers. The carding device comprises a clockwise carding roller and an anticlockwise carding roller which are used for carding long fibers and short fibers; the angles oftooth rollers at the ends of the two carding rollers are oblique angles; and the positions, corresponding to the two carding rollers, of the top of the carding device are each provided with a feedingport for feeding fiber raw materials. According to the wool yarn spraying machine, the double-feeding and double-carding device is adopted, so that carding of long fibers and short fibers is compatible; the angles of the tooth
