Description
Technical Field
The invention belongs to the technical field of auxiliary facilities in optical fiber production, and particularly relates to an optical fiber twisting device.
Background
The twisting of the optical fiber aims to make the optical fiber rotate clockwise or anticlockwise at a certain frequency, turns and speed in the drawing process, so that the polarization mode dispersion of the optical fiber is reduced. The english abbreviation of polarization mode dispersion is PMD (english full name: polarization Mode Dispersion).
It is currently common practice to twist an optical fiber by providing a counter-torque twisting device at the end of a drawing apparatus to thereby reduce the PMD value of the optical fiber, and experiments prove that the measure has a good effect on reducing PMD. However, since the pair of the contusion type twisting device twists the optical fiber by the front twisting guide wheel and the back twisting guide wheel at a certain angle and speed, the requirements on the flexibility, the surface quality, the dynamic balance state and the like of the rotation of the twisting guide wheel are very strict, and in the actual use process, if the two twisting guide wheels are required to be adjusted to be in a good twisting state on the optical fiber, more precisely, the user is required to have a sufficient professional level. In addition, under high-speed drawing conditions, breakage or fluctuation of PMD values is easy to cause, and when an optical fiber breaks, the optical fiber can whip the twisting wheel to cause scratches on the twisting wheel, and once the twisting wheel is scratched, the scratches scratch can scratch the optical fiber coating, and the optical fiber breaks in the drawing process.
