Description

technical field [0001] The invention relates to a centralized automatic control switching feeding system and a control method thereof in the field of optical fiber manufacturing. Background technique [0002] During the wire drawing process, the optical fiber coating system needs to continuously provide coatings. The traditional method is to equip each production line with an independent coating supply system. The small coating buckets directly supply the coating cups, and the large coating buckets supply the small coating buckets. . Manually replace the 10kg bucket of paint directly to the paint vat. The traditional feeding method has the following disadvantages: [0003] 1. The traditional feeding system is to use the purchased 10kg barrel paint to preheat and let it stand, and then the operator puts it in the paint vat for use. Due to the rapid consumption of paint, operators need to frequently replace new paint. This increases the workload and labor intensity of the ...

Problems solved by technology

Due to the rapid consumption of paint, operators need to frequently replace new paint

This increases the labor load and labor intensity of the operator and affects work efficiency.

[0004] 2. The traditional feeding system requires the operator to frequently disassemble the sealed lid of the paint vat and replace the paint barrel, so it is easy to be contaminated by impurities, and it is easy to generate air bubbles during the replacement process, which will lead to abnormal production of optical fibers and coating. Defects lead to waste products; in addition, in severe cases, operators will replace two different coatings by mistake due to frequent replacements, resulting in batches of products being scrapped, and need to stop processing to clean the coating system, resulting in an increase in the shutdown rate of the production line , the output decreases and the cost increases;

[0005] 3. In the traditional feeding system, if the paint is not replaced in time, the paint in the paint bucket is not replenished in time after it is empty, which will also lead to fiber breakage in the production line, or uncoated optical fibers, and the coating pipe is full of air, causing Waste of raw materials, increasing production costs
