Optical fiber back-twisting device

Abstract

The invention relates to the field of optical fiber manufacturing equipment and discloses an optical fiber back-twisting device comprises a raw material loading mechanism, a raw material gathering table, a stranding machine, a back-twisting frame body and a traction mechanism, wherein the raw material loading mechanism, the raw material gathering table, the stranding machine, the back-twisting frame body and the traction mechanism are arranged along a straight line, a first back-twisting mechanism, a second back-twisting mechanism and a third back-twisting mechanism are arranged in the back-twisting frame body, first via holes are formed in the outer walls of the left side and the right side of the back-twisting frame body, the first back-twisting mechanism is installed on the inner side wall of the back-twisting frame body and located under the first via holes, and the second back-twisting mechanism and the third back-twisting mechanism are arranged on the other inner side wall of theback-twisting frame body at intervals. Through the first back-twisting mechanism, the second back-twisting mechanism and the third back-twisting mechanism, the twisting force generated by the opticalfibers during processing can be greatly counteracted, and the production quality is improved.

Description

technical field [0001] The invention relates to the field of optical fiber manufacturing equipment, in particular to an optical fiber untwisting device. Background technique [0002] Optical fiber is the abbreviation of optical fiber, which is a light transmission tool achieved by the principle of total reflection of light in fibers made of glass or plastic. The tiny fiber is encapsulated in a plastic sheath that allows it to be bent without breaking. Typically, a transmitter at one end of the fiber uses a light-emitting diode or a laser to send pulses of light into the fiber, and a receiver at the other end of the fiber uses a photosensitive element to detect the pulses. [0003] In daily life, optical fibers are used for long-distance information transmission because the loss of light in optical fibers is much lower than that of electricity in wires. [0004] Usually the terms optical fiber and optical cable are confused. Most optical fibers must be covered with several ...

Problems solved by technology

With the research and development of high-precision optical fiber rings and other products, the indicators of optical fibers have been continuously refined. Among them, the problem of optical fiber torsion has always been a key concern, which is mainly reflected in the various types of optical fibers currently on the market due to the objective process and production equipment. Factors have always been the inevitability and uncertainty of fiber torsion, which cannot be effectively solved by existing technologies
