Description
Technical field
The invention belongs to the technical field of optical fiber production, particularly relate to the traction apparatus of a kind of fiber secondary coating.
Background technology
Fiber secondary coating technique selects suitable macromolecular material exactly, uses extrusion process, at rational technique bar
Under part, put a Loose tube the most suitable with fiber lengths to optical fiber.Between sleeve pipe and optical fiber, it is full of one simultaneously
Chemical and physical properties is steady in a long-term, viscosity is suitable, water resistance is excellent, have long-term good protection performance to optical fiber, and with
The mixture that shell material is fully compatible, is called for short fine cream.Optical fiber moves freely space, therefore optical fiber after secondary coating in pipe
Tension, lateral pressure resistant ability preferable.
Remaining long formation mechenism: optical fiber by extrusion head through unwrapping wire guide wheel, is inserted PBT sleeve pipe, and filled in sleeve pipe
Fine cream, is drawn by disc type traction wheel, and optical fiber and sleeve pipe are locked on disc type traction wheel.Optical fiber is made by laying tension
With can on disc type traction wheel inside sleeve pipe close, thus Optical Fiber Winding diameter is certainly less than the coiling diameter of sleeve pipe, is formed
Certain is negative remaining long.Due to hot water or cold water's temperature difference after sleeve pipe entrance cold rinse bank, PBT can produce cold events, not only compensate for it at dish
Bearing on formula traction wheel is remaining long, and has obtained required just remaining length.Sleeve pipe is through auxiliary traction tension force and the work of takeup tension
With available required plus-efl value.
The velocity-stabilization of the most domestic fiber secondary coating production line is at about 350m/min, if by the speed of production line
Degree improves to 600m/min, then meet the cool time that sleeve pipe is same, it is necessary to the length increasing bosh ensure that.
Like this length of production line can reach more than 50m, and this is that optical cable manufacturer is not intended to see.Increase tank simultaneously
After length, the distance that sleeve pipe contacts with tank is elongated, then the resistance suffered by sleeve pipe can be greatly increased, the remaining long stability of impact.
Traditional fiber secondary coating traction, main traction wheel shaft is placed in parallel with secondary traction wheel shaft, sleeve pipe transition between wheel
Time unstable, there is jitter phenomenon, thus cause the most disconnected fine or remaining long instability.
Summary of the invention
The technical problem to be solved is the problem for above-mentioned existence, it is provided that a kind of fiber secondary coating
Traction apparatus, integrated equipment structure meets 600m/min the most higher linear velocity requirement, it is ensured that the most fine in distraction procedure.
The present invention solves above-mentioned technical problem and be the technical scheme is that the traction apparatus of a kind of fiber secondary coating,
It is characterized in that, including water tank, traction wheels and water cooling plant, described water tank is all located at by described traction wheels and water cooling plant
In, water cooling plant is arranged relative to traction wheels, and traction wheels include main traction wheel, secondary traction wheel, main traction wheel motor and pair
Traction wheel motor, the axis of described main traction wheel is positioned on different level with the axis of secondary traction wheel.
By such scheme, described water cooling plant includes water injector, baffle device for water and water storage back-up ring, described water injector bag
Including top nozzle and lower nozzle, described top nozzle is located at described main traction wheel and the top of secondary traction wheel top center line, described
Lower nozzle is located at described main traction wheel and the top of secondary traction wheel bottom centre line, and described baffle device for water is water fender, described
Water fender is located at main traction wheel and the lower section of secondary traction wheel top center line, and described water storage back-up ring is arc frid, described arc
Shape frid arranging around fine section relative to main traction wheel.
By such scheme, described main traction wheel and the secondary axial connecting line of traction wheel are 1 °～10 ° with the angle of horizontal plane.
By such scheme, described secondary traction wheel is coaxially multi-disc to take turns, and sheet number is 5～20；It is alternatively monolithic wheel, on wheel
It is provided with 5～20 grooves.
By such scheme, the water level in described water tank is less than the bottom of described main traction wheel.
The invention has the beneficial effects as follows: 1, the traction apparatus of a kind of fiber secondary coating is provided, use main traction wheel with secondary
The structure of traction wheel, integrated remaining long traction and water tank, water tank length and equipment total length can be greatly shortened, reduce sleeve pipe at water
Running resistance in case, can meet 600m/min the most higher linear velocity requirement；2, main traction wheel shaft has with secondary traction wheel shaft
Certain angle, sleeve pipe transition between wheel is steady, and secondary traction wheel uses motor to drive, and reduces running resistance, it is ensured that constantly fine.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention.
Wherein: 1-water tank, the main traction wheel of 2-, 3-pair traction wheel, 4-top nozzle, nozzle under 5-, 6-water fender, 7-arcuate groove
Plate.
Detailed description of the invention
For being more fully understood that the present invention, the invention will be further described with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, the traction apparatus of a kind of fiber secondary coating, including water tank 1, traction wheels and water cooling plant, lead
Running wheel group and water cooling plant are all located in water tank, and water cooling plant is arranged relative to traction wheels, and traction wheels include main traction wheel
2, secondary traction wheel 3, main traction wheel motor and secondary traction wheel motor, major and minor traction wheel drives with major and minor traction wheel motor respectively,
Guaranteeing that the linear velocity of major and minor traction wheel is consistent, when high linear speed traction optical fiber, it is ensured that constantly fine, secondary traction wheel is can be coaxial
Multi-disc is taken turns, and sheet number is 5～20；Being alternatively monolithic wheel, wheel is provided with 5～20 grooves, the axis of main traction wheel and secondary traction
The axis of wheel is positioned on different level, and main traction wheel and the secondary axial connecting line of traction wheel are 1 °～10 ° with the angle of horizontal plane,
