The invention belongs to the technical field of photo-communication, and discloses a
fiber winding and unwinding device group of a
bare fiber. The
fiber winding and unwinding device group of the barefiber comprises a
fiber winding device and a fiber unwinding device; the fiber winding device comprises a first fiber winding disc, a
crank and a first rotating shaft; the first rotating shaft is sleeved with the first fiber winding disc, and the
crank is fixedly arranged on the first winding disc; the fiber unwinding device comprises a clamping block, a connecting shaft, a second fiber winding disc, a fiber unwinding rod and nuts; the clamping block is arranged on a
station, one end of the connecting shaft is fixed on the clamping block, the other end of the connecting shaft penetrates through a central through hole of the second fiber winding disc and a through hole of the fiber unwinding rod in sequence and is fixed through the nuts; the through hole of the fiber unwinding rod is internally provided with a
ball bearing, the fiber unwinding rod is a straight rod, the middle section of the straight rod is provided with a threaded hole, the threaded hole is used for installing a
ball screw, the
tail end of the straight rod is provided with an arc-shaped sliding groove, and the arc-shaped sliding groove is tangent to the second fiber winding disc. The fiber winding and unwinding device group of the
bare fiber solves the problems that the fiber winding and unwinding efficiency of
bare fiber in the prior art is lower and fiber damage is easy to cause.
