Description

Non-contact optical fiber twisting device

Technical Field

The application relates to the field of optical fiber production, in particular to a non-contact optical fiber twisting device.

Background

In the conventional optical fiber twisting device, two twisting wheels are used for clamping an optical fiber, and the optical fiber is twisted in a left-right swinging mode. The positioning wheel plays a role in preventing the optical fiber from deviating in the twisting process. The most important disadvantage of this device is that two twisting wheels are needed to clamp the optical fiber, if the clamping force is too small, the optical fiber cannot be twisted, and if the clamping force is too large, the optical fiber is easily damaged. Even if a reasonable clamping force is adjusted, certain sliding friction is inevitably generated in the actual drawing process, so that the surface coating of the optical fiber is scratched, and the fiber breaking frequency is increased. In addition, the wheel is easy to damage during high-speed operation, and if the wheel is damaged, the optical fiber is scratched or broken.
