Buffered optical fiber lubricating layer production device

Abstract

The invention discloses a buffered optical fiber lubricating layer production device. The buffered optical fiber lubricating layer production device comprises an optical fiber, a hot drying oven, an optical fiber transmission device and a water circulation device; the water circulation device comprises an upper water tank, a lower water tank, a pipeline and a pump; an aqueous solution is arrangedin the upper water tank and the lower water tank; an upper opening and a lower opening for optical fiber movement are respectively formed in the upper end and lower end of the upper water tank; the upper opening is provided with a coating mould; the opening of the coating mould is made of a hydrophobic nano-technical composite material made by using the nanotechnology; the lower water tank is located below the lower opening; the optical fiber passes through the lower opening, the upper opening, the coating mould and the hot drying oven and extends out from the upper part of the hot drying oven; the pump is arranged in the lower water tank; and the pump is connected with the upper part of the upper water tank through the pipeline to achieve the circulation of the aqueous solution. Accordingto the buffered optical fiber lubricating layer production device of the invention, the optical fiber is coated with the aqueous solution; heated is performed by the hot drying oven, so that a bufferlayer can be formed, and therefore, adhesion between the coating layer and tight sheath layer of the optical fiber can be avoided; and water is adopted as a carrier for a lubricant solution, and therefore, the buffered optical fiber lubricating layer production device is harmless to human health and the environment.

Description

technical field [0001] The patent of the present invention relates to a tight-buffer optical fiber manufacturing technology, in particular to a production device for a buffer-type tight-buffer optical fiber lubricating layer. Background technique [0002] Tight-buffered optical fiber is a kind of optical fiber protection method in the production of optical cables. It protects the optical fiber by precisely extruding a layer of tight-buffered layer covering the surface of the optical fiber and improves the mechanical properties of the optical fiber. Due to the heat shrinkage of the tight-buffered material after extrusion, It is easy to cause poor stripping performance of tight-buffered optical fibers, which in turn leads to attenuation problems, especially when materials with high extrusion temperature and high shrinkage such as nylon and TPU are used as tight-buffered materials. [0003] At present, many improvements have been made to the tight sleeve method in the industry ...
