Description
Technical field
The present invention relates to a kind of wire-drawing frame of silica fibre, the device of a kind of horizontal wire drawing silica fibre of saying so more specifically.
Background technology
Existing silica fibre drawing wire machine is vertical wire drawing, be commonly called as wire-drawer-tower, its basic structure is the top of the e Foerderanlage of preform and prefabricated rods at wire-drawer-tower, be downwards process furnace successively, the optical fiber cooled region, the polymer coating unit, optical fiber towing mechanism and optical fiber wrap-up, along with improving constantly of drawing speed, the cooling of optical fiber becomes a bigger problem, present terms of settlement is the cooled region that extends on the one hand, use cooling gas on the other hand, the former certainly will increase wire-drawer-tower, thereby have higher requirement to the rigidity of wire-drawer-tower and to the protection of vibration, the cost of wire-drawer-tower is sharply increased, and the latter also is more and more higher to the requirement of cooling gas, when the low speed wire drawing, use purified nitrogen just passable, and along with the raising of drawing speed, the helium of having to now use, and helium also is more expensive, also be a kind of quite rare gas on earth, these have all limited the further raising of drawing speed of optical fiber and the reduction of optical fiber cost, in addition, along with increasing substantially of optical communication capacity, requirement to optical fiber is also more and more higher, when high capacity communication optical fiber, polarization mode dispersion to optical fiber has also proposed requirement, existing way is to increase to make swivel arrangement in the drawing optical fibers on wire-drawer-tower, reduce polarization mode dispersion, this further makes the wire-drawing frame complexity again, present high-speed wire-drawing machine again surplus in the of 40 rice high, increase again and highly be not easy.In addition, the main raw silica glass of the prefabricated rods of optical fiber is a kind of special material, even be heated to 2300 degree high temperature near gasification, also is a kind of very heavy-gravity liquid, and this point also provides possibility for its horizontal wire drawing.
Summary of the invention
The object of the present invention is to provide the horizontal wire-drawing frame of a kind of optical fiber, this device not only can further improve the drawing speed of optical fiber, also for cooled region and that it(?) may for using cheap cooling gas to provide is provided greatly, the use of this device can reduce the wire-drawing frame cost and the running cost of optical fiber, thereby reduces the cost of optical fiber.
For realizing purpose of the present invention, the horizontal wire-drawing frame of a kind of optical fiber that the present invention discloses, it is characterized in that, the prefabricated rods placed horizontally of optical fiber is in the prefabricated rods clamping convey device, and this device makes the prefabricated rods rotation with certain speed, wire drawing end in prefabricated rods is a process furnace, the process furnace back is the optical fiber cooled region, cooled region is the space of base closed, have in the bottom of cooled region placed side by side, upwards spray the nozzle of cooling gas, be polymer coating unit, optical fiber towing mechanism and optical fiber wrap-up successively behind cooled region.
Described optical fiber cooled region has optical fiber external diameter test set.
Optical fiber external diameter monitoring device is arranged behind described polymer coating unit.
Use the horizontal wire-drawing frame of this optical fiber, not only can further improve drawing speed, reduce the optical fiber cost, and because it has used prefabricated rods rotation wire-drawing technology, can produce spin fiber, reduce the polarization mode dispersion of optical fiber significantly, this optical fiber can be applied in the jumbo opticfiber communication cable, so the horizontal wire-drawing frame of this optical fiber has popularizing value.
Should be appreciated that the general introduction of front and following detailed description all are exemplary, rather than limitation of the present invention.
Description of drawings:
Fig. 1 is the synoptic diagram according to the horizontal wire-drawing frame of optical fiber of the present invention.
Among the figure:
The 1-preform, swivel arrangement, 3-process furnace, 4-optical fiber cooled region are carried in the clamping of 2-prefabricated rods, 5-cooling gas nozzle, the closure casing of 6-cooled region, 7-optical fiber external diameter test set, 8-polymer coating unit, 9-optical fiber external diameter test set 10-optical fiber towing mechanism, 11-optical fiber wrap-up, 12-optical fiber, the 14-of 13-control center fiber reel.
Embodiment
Fig. 1 is the horizontal wire-drawing frame synoptic diagram of optical fiber according to the present invention.Preform 1 is fixed in the prefabricated rods clamping to be carried on the swivel arrangement 2; the prefabricated rods clamping carries swivel arrangement 2 on the one hand preform 1 to be advanced to process furnace 3; make preform 1 rotation with certain speed on the one hand; the optical fiber 12 that wire drawing is come out passes optical fiber cooled region 4; be mounted with cooling gas nozzle 5 side by side in optical fiber cooled region 4 bottoms; the cooling gas nozzle 5 upwards cooling gas of ejection makes the optical fiber cooling on the one hand; optical fiber 12 is suspended in the air by the cooling gas of ejection on the other hand; it outside optical fiber cooled region 4 closure casing 6 that cools off the zone outside the basic sealing chamber; closure casing 6 can keep the clean state of optical fiber cooled region 4 inside; prevent dust; impurity such as steam are to the erosion of optical fiber 12; cause the reduction of the intensity of optical fiber 12; behind the closure casing 6 of cooled region, be mounted with optical fiber external diameter test set 7; by optical fiber external diameter test set 7 the optical fiber external diameter is fed back to control center 13; control center 13 is regulating prefabricated rods clamping conveying swivel arrangement 2; the parameter of process furnace 3 and towing mechanism 10; make the external diameter of optical fiber 12 keep stable; cooled optics 12 enters into polymer coating unit 8; polymer coating unit 8 gives bare fibre 12 outer one deck protectiveness macromolecular materials that apply; 9 pairs of optical fiber external diameter test sets have optical fiber 12 outside diameter measurings of coat; and feed back to control center 13; the parameter that control center 13 regulates polymer coating unit 8 is kept the stable of optical fiber 12 outer coat external diameters; get off is optical fiber towing mechanism 10 and optical fiber wrap-up 11 successively; optical fiber 12 with coat is wrapped on the fiber reel 14 that is placed on the optical fiber wrap-up at last, so far finishes the drawing production of optical fiber.
Because the horizontal wire-drawing frame of this optical fiber is that horizontal fixed is in ground, can fully guarantee the rigidity and the stability of this equipment, can extend as required owing to its optical fiber cooling apparatus again, just can improve drawing speed on the one hand, select cheap cooling gas on the other hand, thereby reduce the cost of optical fiber, this equipment is suitable for promoting and using as can be seen.
Certainly, the present invention is not limited to the embodiment that the front is introduced, and we can replace whole device with another kind of equivalent arrangements, and do not exceed scope of the present invention.
