Description
Technical field
The present invention relates to a kind of layer-stranding cable production technology, more specifically to a kind of layer-stranding cable production method
In ointment fill process.
Background technology
In Networks of Fiber Communications, in order to ensure transmission performance and the service life of optical fibre in optical cable, optical cable must have
Longitudinal water resistance, therefore must be provided with suitable material water-proof material in optical cable.In layer-stranding cable, using filling intumescent
It is most common method that greasy for preventing water carries out blocking water.Reliably block water to realize the whole cross section of optical cable, in Loose tube diameter
Larger（2.2mm or more than 2.2mm）When, the manufacture method that usual layer-stranding cable adopts is as follows：
（1）Ointment on first directly coating on strengthening core；
（2）Strengthening core after above-mentioned coating ointment controls mould to remove unnecessary ointment by ointment amount；
（3）Strengthening core, sleeve pipe and gasket for packing are passed through stranded passage twisted synthesizing cable；
（4）Factice for filling on the cable core of above-mentioned twisted synthesizing cable again；
（5）Then cover upper jacket toward on cable core again, thus making optical cable.
Shortcoming in actual production process for the above-mentioned this method be can not to strengthen wicking surface effectively be filled so that
Easily the underproof situation of cable core block-water performance in finished cable, and its Producing reason is：1st, produced due to strengthening core deadweight
The sagging strengthening core making after coating ointment is controlling mould through ointment amount（Scrape cream mould）And by stranded passage before twisting point
When, the ointment on surface is scraped off（See Fig. 1）；2nd, strengthen the phosphorus powder of wicking surface or dust controls accumulation in nib stifled in ointment amount
Plug, makes strengthening core surface ointment not enough.These reasons lead to cable core ointment lack of fill after stranding, and optical cable permeability performance does not conform to
Lattice.
Content of the invention
The technical problem to be solved is the shortcoming for prior art cable core ointment lack of fill, provides one kind
Ointment fill process, this ointment fill process can effectively overcome strengthening core ointment lack of fill to lead to optical cable after sheath production
The underproof problem of permeability performance.Using technical scheme as follows：
A kind of ointment fill process it is characterised in that：Comprise the following steps：
（1）Grafting yarn on strengthening core；
（2）Ointment is coated on the strengthening core of above-mentioned grafting yarn；
（3）Strengthening core after above-mentioned coating ointment controls mould to remove unnecessary ointment by ointment amount.
The unnecessary strengthening core of ointment of described removing carries out twisted synthesizing cable with multiple sleeve pipes by stranded passage, then puts
Sheath, just makes optical cable.
Preferably scheme, described step（1）After yarn in middle strengthening core grafting, yarn and strengthening core are in screw shaped, and yarn
Line is the screw thread of projection.
A kind of scheme, the number of described yarn is one.
Another kind of scheme, the number of described yarn is at least two.
More excellent scheme, described any two one threads are grafting or reverse grafting in the same direction.
Preferably scheme, described yarn is made using polyester material.Yarn can also other materials be made.
This technique be applied to added with bed course optical cable produce and not cushioned layer metal shielding tangle structure optical cable produce with
And non-metal reinforced layer tangle structure optical cable produce.
Present invention beneficial effect against existing technologies is to carry out ointment filling again after first grafting yarn on strengthening core,
Yarn forms a screw configuration with strengthening core, and yarn is the screw thread of projection, after factice for filling, controls mould, strand through ointment amount
When closing platform entrance and passageway, the yarn of projection makes the ointment of surrounding will not be wiped off completely, keeps reinforcement wicking surface to have enough
Ointment it is ensured that produce after optical cable permeability performance qualified；Strengthening core first carries out ointment filling after wrapping yarn again, when plus
When strong core adopts phosphating steel wire, the grafting pitch due to yarn controls the width of mould big more than ointment amount, and in production, strengthening core is not
When controlling mould by ointment amount with stopping, the phosphorus powder on ointment amount control mould or dust are taken away as brush by the yarn of projection,
Make phosphorus powder or dust will not control accumulation on mould it is ensured that strengthening wicking surface have enough ointment in ointment amount；When using stranding not
Pre-filled ointment and when sheath carries out pressure fill process, prominent yarn is equivalent to and increases strengthening core local diameter, no
The external diameter of impact optical cable, and increase the gap between stranded rear sleeve, during filling, ointment is easier to pass through gap arrival strengthening core table
Face, makes reinforcement wicking surface have enough ointment；This process is easy to implement, only need to be in the gel filling device of former cabling device
Front increase yarn winding device can achieve.
Brief description
Fig. 1 is the schematic diagram that prior art strengthening core of the present invention passes through stranded；
Fig. 2 is preferred embodiment of the present invention step（1）In grafting yarn after strengthening core structural representation；
Fig. 3 is the schematic diagram by stranded passage for the strengthening core that preferred embodiment shown in Fig. 1 removes unnecessary ointment；
Fig. 4 is the structural representation of the strengthening core after preferred embodiment shown in Fig. 1 completes ointment fill process.
Specific embodiment
Ointment fill process in this preferred embodiment it is characterised in that：Comprise the following steps：
（1）Grafting yarn on strengthening core；
（2）Ointment is coated on the strengthening core of above-mentioned grafting yarn；
（3）Strengthening core after above-mentioned coating ointment controls mould to remove unnecessary ointment by ointment amount.
As shown in figure 3, the unnecessary strengthening core 1 of ointment of described removing is twisted by stranded passage 4 with multiple sleeve pipes 3
Synthesis cable, then cover upper jacket, just make optical cable.
As shown in Fig. 2 after yarn 2 in described strengthening core 1 grafting, yarn 2 is in screw shaped with strengthening core 1, and yarn 2 is prominent
The screw thread rising.
The number of described yarn 2 is one.
Described yarn 2 is made using polyester material.
Because the strengthening core 1 after grafting yarn 2 is after factice for filling, through ointment amount control mould, stranded（As Fig. 3 institute
Show）When offseting because of gravity sag and centering, the yarn 2 of projection makes the ointment of surrounding will not be wiped off completely, keeps strengthening core 1 table
Face has enough ointment 5（As shown in Figure 4）；Grafting pitch due to yarn 2 controls the width of mould big more than ointment amount, produces
When middle strengthening core 1 ceaselessly controls mould by ointment amount, ointment amount is controlled the phosphorus powder on mould as brush by the yarn 2 of projection
Or dust takes away, make phosphorus powder or dust will not control on mould accumulation it is ensured that there are enough ointment on strengthening core 1 surface in ointment amount.
When carrying out pressure fill process using the not pre-filled ointment of stranding in sheath, prominent yarn 2 is equivalent to and increases reinforcement
Core 1 local diameter, does not affect the external diameter of optical cable, and increases the gap between stranded rear sleeve, between during filling, ointment is easier to pass through
Gap reaches strengthening core 1 surface, makes strengthening core 1 surface have enough ointment, accordingly ensure that optical cable has good longitudinal waterproof
Property.
