Optical fiber coating paint tank

Abstract

The invention discloses an optical fiber coating paint tank. The optical fiber coating paint tank comprises a paint tank main container and a water jacket container, wherein the paint tank main container is embedded inside the water jacket container, the upper end surface of the paint tank main container is provided with a paint tank handle, and the paint tank main container is sequentially provided with a liquid inlet, a low-level sensor mouthpiece, a compressed air joint and a liquid outlet; the lower end of the liquid inlet is provided with a buffer pipe, the lower end of the buffer pipe isprovided with a guide pipe, and the upper end of the buffer pipe is provided with a breathing port; the upper end surface of the paint tank main container I also provided with the compressed air joint. The optical fiber coating paint tank can avoid being influenced by external paint feeding speed and guide paint to flow into the paint tank main container along the inner and outer walls of the buffer pipe to avoid bubbles due to impact of fluid dropping onto liquid surface; meanwhile, the optical fiber coating paint tank can achieve release of tiny bubbles inside the paint during a flow guiding process to ensure stable paint supply and reduce bubble content.

Description

technical field [0001] The invention relates to the technical field of optical fiber manufacturing, in particular to a coating tank for optical fiber coating. Background technique [0002] In the production process of optical fiber, since the optical fiber drawn from the high-temperature furnace contacts air, it is easy to absorb moisture and dust, which affects the use effect of the optical fiber. Therefore, the coating should be applied immediately after the optical fiber is drawn to protect the optical fiber, so as to avoid the influence of the external environment on the optical fiber. At the same time, the optical fiber coating can also enhance the mechanical strength of the optical fiber and improve the transmission performance of the optical fiber. Therefore, the coating is very important in the production of optical fiber, and it is an important part of the optical fiber. The quality of the coating directly affects the performance of the optical fiber. [0003] In t...
