Optical-fiber annular symmetrical rewinder

The utility model discloses an optical fiber symmetry double wrap device, which comprises a principal axis configuration, a fiber dispose device and a fiber tension device. The principal axis configuration comprises a principal axis which is driven by a principal axis servo electromotor. The principal axis is provided a target optical fiber ring. Two clutches are positioned beside the optical fiber ring. Two fiber supplying ring stepper motors are positioned on the two clutches separately. The two fiber supplying rings are connected with the two fiber supplying ring stepper motors coaxially. Two linear movable power supply arms are arranged at the two side of the two fiber supplying ring stepper motors. The fiber dispose device is a fiber dispose axially movable plate, which comprises a ball bearing screw and a linear guide rail positioned on a base plate. A fiber dispose idler pulley is positioned on the fiber dispose axially movable plate. A fiber dispose stepper motor is connected with the ball bearing screw. The fiber tension device comprises a left movable plate and a right movable plate which crosses with each other, a front movable plate and a back movable plate. The utility model facilitates the relative motionless and the relative movement of the target ring and the fiber supplying rings. The fiber supplying rings are controlled by motors, which can take-up and pay-off fiber conveniently, with adjustable speed.
