Specific embodiment
The manufacture method and manufacture system of a kind of loose tube fiber are embodiments provided, for manufacturing in loose tube fiber
During excess fiber length is controlled, so as to ensure excess fiber length in plastic casing pipe.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is all other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
It is described in detail individually below.
Fig. 1 is refer to, Fig. 1 is a kind of structural representation of the manufacture system of loose tube fiber provided in an embodiment of the present invention,
Including extruding machine 101, the first tank 102 and take-up 104, wherein, the manufacture system also includes：It is arranged at described first
The second tank 103 between tank 102 and the take-up 104, second tank 103 include traction wheel 1031 and spray
Water installations 1032, a part for the traction wheel 1031 are placed in the water of second tank 103, second tank 103
Water temperature is lower than the water temperature of first tank 102；
The extruding machine 101, for optical fiber and fibre ointment are put in the plastic casing pipe at the extruding machine 101；
First tank 102, for carrying out cooling and shaping with the plastic casing pipe of ointment containing optical fiber and fibre；
Second tank 103, for being entered using 1031 pairs of plastic casing pipes through first tank 102 of the traction wheel
Row coiling, meanwhile, 1032 pairs of plastic casing pipes of the water injector are sprayed water, so as to produce loose tube fiber, in coiling and spray
During water, the water temperature for controlling the water temperature and the water injector 1032 of second tank 103 is constant；
The take-up 104, for by loose tube fiber proper alignment in take-up reel.
It is understood that the traction wheel 1031 is per se with rotary power, its linear velocity and plastic casing pipe gait of march
It is roughly the same；In addition, while 1031 coiling plastic casing pipe of the traction wheel, 1032 pairs of plastic casing pipes of the water injector are led
The surface of running wheel 1031 is sprayed water, and is sprayed in second tank 103.1032 pairs of plastic casing pipes of the water injector are
It is to play lubrication that the surface of traction wheel 1031 carries out water spray purpose, prevents the effect of plastic casing pipe surface scratches, while also increasing
The big film-cooled heat of plastic casing pipe.
It should be noted that in second tank 103 water that the water temperature of water is sprayed with the water injector 1032 water
It is warm the same, as plastic casing pipe can distribute heat during operation coiling, cause the coolant-temperature gage in the second tank raise, because
This, during coiling and water spray, in addition it is also necessary to control the water temperature of the water temperature and the water injector 1032 of second tank 103
It is constant.In second tank 103, traction wheel 1031 is controlled to the negative remaining length of loose tube fiber, meanwhile, water temperature is to pine set
The just remaining length of optical fiber is controlled, to ensure the excess fiber length in plastic casing pipe.
Preferably due to the temperature in continuous running of the water in the second tank 103 can change, the speed of operation
Difference, the amount of contraction of plastic casing pipe also can be different, therefore can be directed to different application scenarios, i.e., put in mould set tube material, optical fiber
In the case of each factors such as line tension, main drawing tension, the temperature and pressure change of ointment, by changing plastic casing pipe in traction wheel
On 1031, number of turns N and water temperature of coiling to be adjusting remaining length, number of turns N according to it is required it is remaining it is long adjust, based on below equation and water
Temperature is determined：Wherein, D0It is straight for traction wheel 1031
Footpath；D is plastic casing pipe external diameter；δ is mould set thickness of pipe wall；N is fiber number；LfFor fiber lengths；LtFor mould set length of tube, dfFor light
Fine diameter.Due toSo the excess fiber length that ε ＜ 0, i.e. traction wheel 1031 are produced is negative.Excess fiber length
1031 diameter of traction wheel is less, and the negative remaining length of optical fiber is bigger, and just remaining length is less.Conversely, 1031 diameter of traction wheel is bigger, optical fiber is negative remaining
Length is less, and just remaining length is bigger.
In addition, it is contemplated that in different application scenarios, leading for mould set tube material, optical fiber laying tension, master
The difference of draw tension, the temperature and pressure of ointment, number of turns N of coiling on traction wheel 1031, the second tank 103 and water injector
1032 water temperature is also different, and the water temperature of the first tank 102 is also different in the same manner, it is only necessary to ensure that the water temperature of the second tank 103 compares
The water temperature of one tank 102 is low, is not especially limited herein；
If that is, optical fiber is too short, can control to reduce water temperature, if optical fiber is oversize, can control to improve water temperature,
The embodiment of the present invention is not construed as limiting to water temperature, the concrete value of number of turns N of coiling.
Explanation is analyzed to the manufacture system of the loose tube fiber below for concrete application scene：
