Abstract
The utility model discloses an optical fiber coating filling device, and relates to the technical field of optical fiber manufacture. The optical fiber coating filling device comprises a liquid inlet pipe, a liquid outlet pipe, a high liquid level sensor, a low liquid level sensor and an optical fiber coating container, and is characterized in that: an isolation cover is arranged in the optical fiber coating container; and the orifice of the liquid outlet pipe is positioned in the isolation cover. The optical fiber coating filling device can prevent air bubbles from entering the liquid outlet and being brought into a coating to be coated on the surface of an optical fiber.
Description
Technical field
The utility model relates to the optic fibre manufacturing technology field.
Background technology
In optical fiber production process, need apply coating, will be coated in the paint solidification of optical fiber surface then by the ultra-violet curing technology, reach the purpose that protection optical fiber improves fiber strength at the optical fiber surface that draws out.The padding scheme of optical fiber manufacturing employing now is that two-stage is filled, promptly, be divided into two jars, main jar and auxilliary jar, coating in auxilliary jar by air pressure through pipeline, some row components and parts such as valve, be pressed to main jar liquid-inlet pipe, low liquid level sensor in main jar, find out liquid level open after low auxilliary jar with main jar between valve on the pipeline liquid-inlet pipe of coating by main jar is filled in the main jar, fill behind the high liquid level sensor in filling liquid reaches main jar and stop, be filled into main jar of interior coating and apply mould through the drain pipe arrival in main jar, optical fiber passes and is coated on coating when applying mould.The filling mode that adopts in the optical fiber industry as shown in Figure 1 at present, coating splashes in the container of splendid attire coating through a main jar liquid-inlet pipe, in the process of coating drippage, can be with a part of gas to enter, and generation bubble, the bubble that produces can arrive near the container bottom of splendid attire coating because the inertia that coating falls is followed coating, arrive near the bubble container bottom come-up that also is not able to do in time and just follow coating easily and flow out and be coated on the optical fiber from drain pipe, the coating that is mixed with bubble can cause damage to the intensity and the coating quality of optical fiber.For example bigger bubble is mixed in and is coated in optical fiber surface in the coating and can forms at optical fiber surface and do not have regions coated, and can burst when the UV lamp solidifies, and causes degradation under the fiber strength.
The utility model content
Technical problem to be solved in the utility model is the deficiency at above-mentioned prior art existence, a kind of device is provided, can reduces coating vertical drippage after and bring bubble that ambient air produces into and follow coating and be coated in problem on the optical fiber through drain pipe through main jar of liquid-inlet pipe.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: optical fiber applies coating material charging device, comprise liquid-inlet pipe, drain pipe, high liquid level sensor, low liquid level sensor, the optical fiber coatings container containing is characterized in that, be provided with cage in the optical fiber coatings container containing, the mouth of pipe of drain pipe is positioned at cage.
Described cage is arranged at the bottom of optical fiber coatings container containing, and cage is provided with through hole.Described cage is made of the net that has a plurality of apertures.Described cage lower edge and optical fiber coatings container interior bottom surface are gapped.
Adopt technology of the present utility model, coating is brought surrounding gas into when fluid inlet flows out the bubble that coating produces and is blocked in outside the shelter, slowly come-up disappears, and so can reduce bubble and enter liquid outlet and be brought into into that coating is coated on the optical fiber surface, has improved optical fiber quality.

Embodiment
Referring to Fig. 2,3, optical fiber coatings tamping unit of the present utility model, comprise liquid-inlet pipe 1, drain pipe 2, high liquid level sensor 3, low liquid level sensor 4, pressed gas inlet 5, the container 6 of splendid attire coating is installed on the cage 8 at drain pipe 2 mouth of pipe places, cage 8 has the aperture of a plurality of enough small-bores, particularly the top.Coating is brought surrounding gas into when liquid-inlet pipe 1 mouth of pipe flows out the bubble that coating produces and is blocked in outside the cage 8, and slowly come-up disappears, and so can reduce bubble and enter liquid outlet and be brought into into that coating is coated on the optical fiber surface.
As second kind of embodiment, cage 8 is made of Web materials, and mesh can effectively be isolated from drain pipe with bubble.
