Description

Technical Field

[0001] This utility model relates to the field of optical fiber and cable technology, and in particular to an online optical fiber coloring system. Background Technology

[0002] Optical fibers have a wide range of applications. A single optical cable often contains multiple optical fibers. Since optical fibers have a limited range of colors, they need to be colored or have color rings printed on them to aid in identification. Coloring involves attaching colors to the optical fibers according to standards or usage requirements, so that each of the optical fibers in a single cable has a corresponding color. Printing color rings involves spraying different colors, lengths, and spacing onto the surface of the optical fibers to increase the number and identification of optical fibers in the same sleeve, thereby achieving the purpose of distinguishing optical fibers.

[0003] The equipment used in the optical fiber coloring process is an optical fiber coloring device, which consists of an optical fiber laying section, coloring molds and ink supply system, ultraviolet curing oven, traction, optical fiber take-up, and electrical control components. The optical fiber coloring device is a crucial piece of equipment in the optical fiber and cable manufacturing process, primarily used to coat the surface of optical fibers with a specific color coating to distinguish and identify different fibers. However, currently, the industry commonly uses a method of first producing finished undyed optical fibers, then mounting the coiled undyed fibers onto the coloring device for coloring. This method is extremely time-consuming and inefficient when coloring multiple different colors. Utility Model Content
