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 ...
