Optical fiber producing coating central concentrated feeding system

Abstract

The invention relates to an optical fiber producing coating central concentrated feeding system, and belongs to the technical field of optical fiber manufacturing and processing. The optical fiber producing coating central concentrated feeding system is composed of a raw material feed cylinder, coating bubble detectors, a booster pump, a coating reflux pipe, a main pipe, branches pipes, and a drawing coating pipe; and a coating bubble detecting reflux system and a concentrated feeding system are formed respectively. Only a central feeding station is needed to be replaced when coating replacing is carried out, so that coating replacing frequency is reduced, coating system stability is improved and coating waste is reduced in drawing process, automation degree is high, and labour intensity of workers is reduced. When coating is replaced, problems of the conventional coating system, that about 1kg of coating left in a raw material barrel is wasted, a large amount bubbles are generated in coating replacing process, drawing coating can be carried out after discharging 1 to 3kg of the coating containing bubbles, a large amount of coating is wasted, and production cost is increased, is solved.

Description

technical field [0001] The invention relates to a continuous feeding device, in particular to a central centralized feeding system for optical fiber production and coating. Background technique [0002] With the increasing demand for optical fiber market year by year, the production capacity requirements are increasing day by day. As a part of the optical fiber manufacturing process, second only to variable diameter drawing, the importance of the stability of the coating system is particularly prominent. However, the existing coating system uses raw material barrels of 10 kg per barrel. Each time the paint is replaced, there is still about 1 kg of remaining paint in the raw material barrel that is lost. If there are a lot of bubbles, the paint with bubbles must be drained by 1 to 3 kilograms from each production line before each wire drawing. Otherwise, the production will be affected, the paint will be lost a lot, and the production cost will be increased; and the existing ...

Problems solved by technology

However, the material supply of the existing coating system is to use a raw material barrel of 10 kg per barrel. Every time the paint is replaced, there is about 1 kg of remaining paint in the raw material barrel that is lost, and the paint will be produced during the refueling process. There are a large number of bubbles, and each production line must drain 1 to 3 kilograms of paint with bubbles before each wire drawing, otherwise it will affect production, cause a large loss of paint, and increase production costs; and the existing single-line coating Due to the untimely supply of materials in the coating system, insufficient material supply will cause fiber breakage accidents.
