Embodiment Construction
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0022] An optical fiber coating device disclosed in an embodiment of the present invention realizes two coatings in a set of molds, which effectively shortens the path length occupied by the optical fiber coating process, thereby reducing the construction height of the optical fiber drawing tower and reducing construction costs. At the same time, it effectively reduces resin loss and improves the quality of optical fiber coating.

The invention discloses an optical fiber coating device which includes a primary coating mold and a secondary coating mold, and a UV curing apparatus arranged therebetween. The primary coating mold, the UV curing apparatus and the secondary coating mold are arranged along the path of an optical fiber from top to bottom to assemble an integrated mold. In the optical fiber coating device, primary coating and secondary coating are integrated in one mold, so that the path of coating process is effectively reduced, and further building height of an optical fiber drawing tower is reduced and building cost of the device is reduced. The primary coating and the secondary coating are completed synchronously, so that coating quality is convenient to control. Concentricity of a produced optical fiber is excellent, consumption on resin is effectively reduced and production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of optical fiber coating, in particular to an optical fiber coating device. Background technique [0002] In the drawing production process of optical fiber, the optical fiber needs to be coated on the surface. As an important part of optical fiber production, coating is very important to the quality of the finished optical fiber. Optical fiber coating is a polymer material layer coated to protect the bare optical fiber, improve the mechanical strength and microbending strength of the optical fiber, and reduce attenuation. The main component of the bare optical fiber is silica, which is a brittle and brittle material with poor bending resistance and poor toughness. If several such bare optical fibers are bundled into a bundle, they are prone to wear and tear on each other, resulting in damage to the surface of the optical fiber. At the same time, when the optical fiber is drawn and formed, the probability o...
