Abstract
The utility model relates to a device for coating optical fibers with cladding, which is a closed container in which coating materials are filled. A wire inlet mould and a wire outlet mould are respectively and fixedly connected to a front and a back end covers of the closed container, and mould holes of the wire inlet and the wire outlet moulds are on a same centerline which is arranged below the liquid level line of the coating materials; the upper part of the closed container is provided with a coating material filling and inserting port and a compressed gas inserting port, and a transparent eyehole window for the liquid level line is arranged on the side edge of the closed container; the coating materials are liquid ultraviolet solidifying resin, and compressed gas is nitrogen, helium or other suitable inert gas. The utility model is applied to an optical fiber coating process, optical fibers to be coated enter a barrel body from the holes of the wire inlet mould in 500-1500 meters/ minute, pass through the coating materials and then enter a strong ultraviolet solidifying furnace zone through the holes of the wire outlet mould to be instantly solidified. The utility model has the advantages of good affinity, consistent concentricity to cladding, stable performance and high rate of finished products without generating the phenomena of inner stress and disjunction, and the expansion coefficient of the optical fibers and cladding lines is basically consistent.
Description
Affiliated technical field
The utility model relate to a kind of flowing material coat the surface device, promptly a kind of tightly packaged fiber coating unit.
Background technology
The light transmitting fiber that optical communication is used is the fine filaments that is drawn by fused silica glass; although single commodity optical fiber had been coated with the preliminary protection of one deck resin bed conduct as thin as a wafer; but its intensity is very fragile, needs further to be called tightly packaged fiber behind coating one deck coating, to increase its intensity.Existing tightly packaged fiber adopts and directly extrudes lining one deck flexible PVC, acrylic plastering or other elastic rubber-plastic composite materials in commodity bare fibre outside, and the weak point of this method is that the high temperature that optical fiber will bear extrusion head during by extrusion head easily causes the impaired fracture of optical fiber; The tightly packaged fiber that comes out from extrusion head will enter the tank cooling rapidly, dry up then, but the surface still can remaining certain steam, and optical fiber is produced considerable influence serviceable life; Because optical fiber is very thin, the difficulty of plastic processing is very big when extruding at a high speed, easily causes the eccentric even disconnection of coating plastic layer, and yield rate is low; The linear expansion coefficient of optical fiber and plastics differs bigger, influenced by variation of ambient temperature, easily produces internal stress and causes the transmission performance fluctuation bigger.
Summary of the invention
In order to overcome existing tightly packaged fiber application temperature height, be subjected to high temperature, water, vapour etc. to influence easy impaired fracture, eccentric disconnect, yield rate is low, the deficiency of transmission performance difference etc., the utility model provides a kind of tightly packaged fiber coating unit, it is applied at normal temperatures and be not subjected to temperatures involved, and the coat good concentricity, evenly, good product quality, the yield rate height.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of tightly packaged fiber coating unit is by the closed container of an interior dress coating material, coating material charges into interface, pressure gas access port and turnover line mould are formed, it is characterized in that the front end end cover of fixedlying connected by with the inlet wire mould, the rear end cap and the cylindrical shell of fixedlying connected with the outlet mould are combined into a closed container, in this closed container, be filled with coating material, the nib of inlet wire mould and outlet mould is on same center line, this center line is below the metal line of coating material, be provided with a resin on the top of cylindrical shell and charge into interface and pressure gas access port, on the side of cylindrical shell, be provided with the transparent window window of a liquid level, above-mentioned described coating material is to be the ultraviolet fast-curing resin of liquid under the normal temperature, and above-mentioned described pressure gas is a nitrogen, helium or other suitable inert gases.The coating procedure of optical fiber is like this, it is in the ultraviolet curable resin liquid of liquid that optical fiber enters under the normal temperature the closed container with 500-1500 rice/minute at a high speed from the inlet wire nib, and the surface is stained with one deck coating material resin and is promptly solidify to form one deck tightly packaged fiber coating fast after the outlet nib enters intensive ultraviolet curing oven region normal-temperature following moment immediately.
The beneficial effects of the utility model are that optical fiber applies curing at normal temperatures, is not subjected to temperatures involved, optical fiber and coat linear expansion coefficient basically identical, affinity is good, does not produce internal stress and discrepancy, the good concentricity of coat, evenly, properties of product are stable, quality is good, yield rate is high.
