Description

technical field [0001] The invention relates to the technical field of optical fiber cooling, in particular to a self-adjusting optical fiber cooling device based on centrifugal force transmission. Background technique [0002] Since the optical fiber is obtained by drawing the optical fiber preform, the optical fiber still reaches a high temperature of about 1000°C when it comes out of the furnace, that is, after the optical fiber is formed, it is squeezed in the limited interval from the furnace mouth to the winding station or from the furnace mouth to the outside. The limited section of the package is not enough to reduce the temperature of the optical fiber from about 1000°C to the level similar to the ambient temperature by natural cooling. Therefore, it needs to be cooled before it can enter the next process. [0003] The traditional optical fiber cooling is to pass the optical fiber through the cylinder equipped with air-cooling and water-cooling systems, and fill ine...

AI Technical Summary

Problems solved by technology

[0003] The traditional optical fiber cooling is to pass the optical fiber through the cylinder equipped with air-cooling and water-cooling systems, and to speed up the heat dissipation by filling inert gas, while the position of the traditional air-cooling tube and the optical fiber are relatively fixed, so that the same circle The cooling effect of the optical fiber on the cross-section is uneven, which reduces the cooling effect, and the traditional cooling device cannot automatically adjust the cooling degree according to the speed of the optical fiber transportation. When the optical fiber is in contact with the inert gas for too long, it is easy to be affected by gasification air and reduce the quality

[0004] In order to solve the above problems, the inventor provides a self-adjusting optical fiber cooling device based on centrifugal force transmission, which can make the air-cooled tube rotate around the periphery of the optical fiber, thereby making the cooling of the optical fiber more uniform and improving the cooling quality. The cooling effect is adjusted by the speed of optical fiber transmission, which avoids the phenomenon of insufficient optical fiber cooling and the reduction of optical fiber quality due to the influence of vaporized air
