Optical fiber coating feed system with return prevention function

Abstract

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. The system is composed of a paint bucket storage tank, a buffer bucket and a coating cup. A paint bucket is placed in the paint bucket storage tank. The paint bucket storage tank is equipped with a storage tank cover. Inside, a solenoid valve is installed on the intake pipe; a buffer barrel cover is installed on the upper part of the buffer barrel, and an inner interlayer is arranged in the buffer barrel; three liquid level sensors are installed on the buffer barrel cover, and the liquid level sensor I is installed on the upper part of the buffer barrel, and the liquid level sensor II is installed at the bottom of the buffer tank. There is an overflow port on the upper side of the interlayer in the buffer tank, and a liquid level sensor III is installed on the top of the other side. The side of the buffer tank is equipped with an air intake pipe; between the paint tank storage tank and the buffer tank It is connected with a feed pipe, which is respectively inserted into the bottom of the paint bucket storage tank and the buffer bucket, and a liquid solenoid valve is installed on the feed pipe; the buffer bucket and the coating cup are connected with a discharge pipe. The system is reasonable in design, cheap in cost and simple in structure, and can effectively inhibit the paint returning site, and has wide application prospects.

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...

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
