Abstract

The utility model provides an optical fiber coating tank relating to the technical field of optical fiber manufacture. The optical fiber coating tank comprises a liquid inlet tube, a liquid outlet tube, a high liquid level sensor, a lower liquid level sensor and an optical fiber coating containing vessel, wherein a floating device is movably installed on the liquid outlet tube and forms sliding matching with the liquid outlet tube, and the outlet of the liquid inlet tube is close to the outer wall of the liquid outlet tube. With the adoption of the utility model, coating which flows out of the liquid inlet tube port is guided and falls down along the liquid outlet tube wall; as the liquid outlet tube is sleeved with a floating ball, the coating can be guided by the floating ball when flowing through the floating ball, namely the direction of the coating is changed, the coating is not directly inertially impacted to the nearby part of the liquid outlet tube port, therefore, the amount of bubbles entering the liquid outlet can be reduced, brought into the coating and coated on the optical fiber surface.

Description

The optical fiber coatings jar

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 feed tube, low liquid level sensor in main jar, find out liquid level open after low auxilliary jar with main jar between valve on the pipeline feed tube 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 is at present, coating splashes in the container of splendid attire coating through a main jar feed tube, 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.As shown in Figure 1.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, at the deficiency that above-mentioned prior art exists, provide a kind of coating that can solve after through main jar feed tube, to bring the bubble that surrounding air produces in the dropping process into and follow coating is coated in the problem on the optical fiber through drain pipe optical fiber coatings jar.

The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: the optical fiber coatings jar, comprise feed tube, drain pipe, high liquid level sensor, low liquid level sensor and optical fiber coatings container containing, it is characterized in that, be movably installed with flotation gear on the drain pipe, described flotation gear and drain pipe form and are slidingly matched, and the outer wall of drain pipe is pressed close in the outlet of feed tube.

Described flotation gear is provided with through hole, and drain pipe passes described through hole.Described flotation gear is a ball float.

Adopt the utility model, the coating that the feed liquor mouth of pipe flows out falls along drain pipe tube wall water conservancy diversion, because drain pipe is with ball float, when flowing through ball float, can be shunted coating by ball float, promptly change the flow direction of coating, be not direct inertia impact near the drain pipe mouth of pipe, so can reduce bubble and enter liquid outlet and be brought into into that coating is coated on the optical fiber surface.

The utility model is described in further detail below in conjunction with description of drawings and the specific embodiment.

Description of drawings

Fig. 1 is the structural representation of existing coating material charging device.

Fig. 2 is a structural representation of the present utility model.

Among the figure 1 is feed tube; The 2nd, drain pipe; The 3rd, high liquid level sensor; The 4th, low liquid level sensor; 5 pressed gas inlet; The 6th, the container of splendid attire coating; The 7th, optical fiber coatings; The 8th, flotation gear.

The specific embodiment

Referring to Fig. 2, optical fiber coatings filling device of the present utility model comprises feed tube 1, drain pipe 2, and 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 flotation gear 8 on the drain pipe 2.The outside of drain pipe 2 is pressed close in the outlet of feed tube 1, after flowing out from feed tube 1 mouth of pipe, coating can flow downward when arriving flotation gear 8 along the drain pipe outer wall, coating was away from drain pipe when thereby flow direction was disperseed finally to fall, and so can reduce the bubble that produces in the coating dropping process and enter near the liquid outlet and be brought into into that coating is coated on the optical fiber surface.Consider the surface tension of the viscosity and the drop of coating itself, can leave certain distance between the outer wall of the outlet of feed tube 1 and drain pipe 2; Also can contact, but should leave enough spaces so that coating flows smoothly.

The flotation gear of present embodiment is a ball float, is provided with through hole in the ball float, forms with drain pipe 2 to be slidingly matched.

Specification has clearly illustrated principle of the present utility model and necessary technology details, and those of ordinary skill can be implemented fully.Interest field of the present utility model is not limited to previous embodiment.
