Process Of D2 Friction Spinning Machine

4 ~ 6 fiber slivers are taken out from the can and fed into the three-roller drafting device 1. After the fiber sliver passes through the drafting, its uniformity and fiber straightness are improved, and it is combed and decomposed by the carding roller 2. In a single fiber state, under the action of the centrifugal force of the carding roller and the airflow of the blower tube 3, it is separated from the sawtooth, and falls along the baffle 4 into the wedge-shaped groove between the two dust cages. Wedge-shaped grains, one end is connected to the fan through a pipe. Under the suction of the suction device, the fibers are absorbed in the wedge-shaped grains of the two dust cages, condensed into whiskers, and the yarn introduction is introduced into the dust cage and overlapped with the condensed whiskers. The yarn pulling roller 7 holds and outputs, and the two dust cages rotate in the same direction to twist the condensed strands into yarn, and the output yarn is frictionally wound into a package by the winding roller 8.
