Coloring mold and coloring method for color stripe optical fiber

Abstract

The invention belongs to the technical field of optical fiber coloring, and particularly relates to a coloring mold of a strip optical fiber. The mold comprises a frustum cone-like mold body, wherein a fiber passing hole is formed in the mold body. The mold is characterized in that the outer surface of the side face of the mold body outwardly extends to form an ink feeding device; an ink inlet is formed in the center of the ink feeding device and is communicated with the fiber passing hole; the joint of the ink inlet and the fiber passing hole is positioned close to the lower side of the fiber passing hole; the ink inlet and the fiber passing hole are relatively inclined; a frustum cone-like large section is formed on the upper part of the mold body; a sunken groove is formed in the upper part of the mold body; an arc stripe groove is formed from the lower side of the joint of the fiber passing hole and the ink inlet to the bottom of the mold body; the arc stripe groove is communicated with the fiber passing hole, and the outer arc diameter of the arc stripe groove is more than the diameter of the fiber passing hole. The invention further discloses a coloring method. The coloring mold mainly has the beneficial effects that the structure is simple, the manufacture is easy, ink can be saved while identification is not influenced after the coloring mold is used, electricity is saved, the coloring speed is high, the service life of a curing light is long, and the coloring curing degree is high.

Description

technical field [0001] The invention belongs to the technical field of optical fiber coloring, in particular to a coloring mold and a coloring method for color-striped optical fibers. Background technique [0002] As the main carrier of communication, the use of optical fiber is increasing day by day; at present, optical fiber is mainly used in the field of signal transmission, such as mobile phone signals, TV signals, control signals, monitoring signals, etc., and the commonly used optical fibers are silica-based optical fibers. From the inside to the outside, it is composed of core, cladding, and coating. The nominal diameter of the coating is 245 μm. In the prior art, in order to increase the communication capacity, it is usually necessary to put multiple optical fibers together. In order to facilitate identification, Ink is usually applied to the outer circumference of the coating layer, which is called coloring. The main purpose of the coloring layer is to facilitate i...

Problems solved by technology

The main purpose of the coloring layer is to facilitate identification. In the prior art, the circumferential coating uses a large amount of optical fiber ink, which does not meet the requirements of low-carbon environmental protection, and the ink is a toxic and harmful substance, so it should be used as little as possible.
