Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber coloring, and particularly relates to an optical fiber coloring device. Background Art

[0002] In the production of optical cables, we will coat different colors of ink on the surface of bare optical fibers according to actual needs for identification, which is convenient for later laying, connection, use and maintenance. The optical cable standard stipulates 12 different colors for easy identification, and several of them will be selected from them in the same tube according to actual needs. However, when the number of optical fibers exceeds 12, this method is difficult to meet the production and use needs. Using the method of spraying color rings first and then coloring will result in the situation of partial color ring missing and coloring die blockage; since the color ring is only sprayed on the surface of the bare optical fiber, the adhesion of the color ring ink itself is not strong, and it can be seen that there is ink on the hand when gently wiped with the hand. When coloring, the bare optical fiber with the sprayed color ring will continuously contact and rub with the guide wheel on the coloring machine, so part of the color ring ink will be removed, resulting in missing.

[0003] The optical fiber with the sprayed color ring passes through the coloring die for a long time during production, which will cause the black ink to accumulate in the coloring die core, resulting in die blockage and the situation of too large attenuation of the optical fiber.
