Description

A feeding device for optical fiber coating

technical field

The utility model relates to a feeding device, in particular to a feeding device for optical fiber coating.

Background technique

In the process of optical fiber production, it is necessary to coat the surface of the drawn bare optical fiber. The function of coating is to protect the surface of the optical fiber from mechanical damage and moisture and maintain its original strength. Therefore, the coating quality has a great impact on the optical fiber. The performance of the optical fiber has a great influence, and the quality of the coating process will directly affect the coating quality of the optical fiber. At present, the commonly used coating feeding system mainly consists of centralized feeding and single-line separate feeding. The centralized feeding method is mainly to feed the small paint buffer barrels of multiple production lines through a large paint storage tank, and then apply paint to the bare optical fiber in the mold through the small paint buffer barrels. The main disadvantage of this feeding method is that the device Huge volume, complex structure, and large waste of paint; single-line separate feeding is that each production line is equipped with a separate paint storage tank, and each production line feeds from its own paint storage tank to a small paint buffer tank, and then through the small paint buffer tank to the bare paint in the mold. Optical fiber coating, the main disadvantage of this feeding method is that the coating needs to be manually poured into the coating storage tank before or during the production process, and the entire process will cause bubbles in the coating, which will affect the coating quality. In addition, the same point of the above two methods is that both need to pressurize the paint from the storage tank to the buffer barrel. At present, the length of the drawn optical fiber of a single preform can reach more than 4000km, which requires frequent actions of pressing the coating from the storage tank into the buffer bucket. overlay quality.
