S5, tension screening: colored optical fiber is placed in optical fiber pay-off rack, utilizes unwrapping wire sensor and laying tension measurement wheel
The size of laying tension is obtained, the adjustment to laying tension is completed by tension adjustment wheel.Optical fiber is heated to through optical fiber pre-heater
A certain temperature, temperature cannot be excessively high, otherwise will cause the increase of optical fiber micro-bending；
S6, coating processes: providing a constant hauling speed using traction device, meanwhile, by macromolecule material from extrusion molding
The feed inlet of machine is packed into the charging zone of extruding machine and preheated area and heats, and forms molten state material of sticky shape, passes through extruding machine
Interior mold pulls into tubulose, and so that the thick fixed close adhesive bond of coating material of second melting state is existed by inhaling vacuum plant
On optical fiber and any surface finish, the optical fiber having been coated with will be come out from extruding machine and carries out water cooling；
S7, detection: tension screening is carried out again to light optical cable after molding.
Preferably, entire process flow uses sealing structure.
Preferably, gas duct interior fills nitrogen in the preparation of light optical cable.
Preferably, colour: coating with a thickness of three layers, one layer is precoated shet, and two layers are buffer layer, and three layers are isolation layer.
Technical effect and advantage of the invention:
1, protect: the preparation of optical fiber cable carries out in the environment of purification constant temperature, the works such as preform, wire drawing, coloring
Sequence should all carry out in the cleaning shop of 10000 grades or more cleanliness.Fibre drawing furnace optical fiber shaping should up to 100 grades with
On.Preform should carry out in sealed environment.All gas pipeline, should all during work interval on fiber manufacturing installation
Nitrogen charging gas shielded avoids moisture in air from entering pipeline, protects the performance of optical fiber cable.
2, quality: the preparation of optical fiber cable is equipped with a whole set of using a whole set of accurate production equipment and control system
For detect and correct each component of optical-fiber processing equipment operating parameter facility and device, the long-term working process parameter that keeps
Stablize, the quality of stable fiber optical cable.
3, tension: optical fiber cable is tension when preheating guarantee production, and optical fiber light can be improved in tension screening twice
Cable finished product is tension.
