Optical fiber coating feed system with revert prevention function

Abstract

The invention provides an optical fiber coating feed system with material revert preventing function in optical fiber manufacture. The feed system is composed of a coating barrel storage tank, a buffer barrel and a coating cup. A coating barrel is placed in the coating barrel storage tank provided with a storage tank cover, the storage tank cover is provided with an air inlet pipe thereon extending into the coating barrel, and an electromagnetic valve is disposed on the air inlet pipe. A buffer barrel cover is provided on the upper part of the buffer barrel provided with an inner interlayer therein. Three liquid level sensors are disposed on the buffer barrel cover, the liquid level sensor I is disposed on the upper part of the buffer barrel, the liquid level sensor II is disposed at the bottom of the buffer barrel, the upper part of one side of the buffer barrel inner interlayer is provided with an overflow port, the top of the other side of the buffer barrel inner interlayer is provided with the liquid level sensor III, and the air inlet pipe is disposed at the side of the buffer barrel. The coating barrel storage tank and the buffer barrel are connected through a feed pipe respectively inserted into the bottom of the coating barrel storage tank and the buffer barrel, and a liquid electromagnetic valve is disposed on the feed pipe. The buffer barrel and the coating cup are connected through a discharge pipe. The inventive feed system has reasonable design, low price, simple structure and wide application range, and effectively inhibits coating revert on spot.

Description

technical field [0001] The invention provides an optical fiber coating and feeding system with the function of preventing material return, which relates to a feeding system for preventing coating material return in optical fiber manufacturing. Background technique [0002] The coating process is an important step in the manufacturing process of communication optical fibers, and plays a pivotal role in all processes of optical fiber manufacturing. There are two commonly used feeding methods for coating: central centralized filling and separate feeding system with the production line as a unit. The former uses a large storage tank system to feed the small coating buckets of multiple production lines, and then uses the small coating buffer buckets to quantitatively coat the bare optical fiber in the mold through the control system. Its main disadvantages are the complex system and high energy consumption; while the latter is based on the production line, and the paint bucket s...

Problems solved by technology

Its main disadvantages are the complex system and high energy consumption; while the latter is based on the production line as a unit, and the paint barrel storage tank is set up separately to fill the small paint buffer barrel, and then the bare optical fiber in the mold is fed by the small paint buffer barrel through the control system. Quantitative coating, its disadvantage is that the small paint buffer tank needs to be frequently fed by pressure during production, especially when the electrical components of the system are abnormal, it is easy to cause material return to the coating cup, etc., causing abnormal fiber optics and production interruption, which affects the equipment operation efficiency
