Abstract
The invention discloses an optical fiber coating tank and relates to the technical field of optical fiber manufacture. The optical fiber coating tank 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, wherein the liquid outlet pipe is movably provided with a floating device; the floating device is in slide fit with the liquid outlet pipe; and the outlet of the liquid inlet pipe is close to the outer wall of the liquid outlet pipe. By the optical fiber coating tank, a coating flowing out of the orifice of the liquid outlet pipe falls off under the guidance of the pipe wall of the liquid outlet pipe; because the liquid outlet pipe is sleeved with a floating ball, and the coating can be divided by the floating ball when flowing through the floating ball, namely the flowing direction of the coating is changed, and the coating does not directly impact to the vicinity of the orifice of the liquid outlet pipe by means of inertia; therefore, air bubbles can be prevented from entering a liquid outlet and being brought into the coating so as not to be coated on the surface of an optical fiber.
Description
Technical field
The present invention relates to the optic fibre manufacturing technology field.
Background technology
In optical fiber production process, need apply coating at the optical fiber surface that draws out, 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.The padding scheme of optical fiber manufacturing employing now is that two-stage is filled, namely, 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 is 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, near the arrival container bottom bubble does not also have enough time to float and just follows coating easily from the drain pipe outflow and be coated on the optical fiber, and the coating that is mixed with bubble can cause damage to 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.
Summary of the invention
Technical problem to be solved by this invention is, at the deficiency that above-mentioned prior art exists, provide a kind of coating that can solve after through main jar liquid-inlet pipe, to bring the bubble that ambient 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 present invention is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is: the optical fiber coatings jar, comprise liquid-inlet pipe, fluid, high liquid level sensor, low liquid level sensor and optical fiber coatings container containing, it is characterized in that, be movably installed with floatation device on the drain pipe, described floatation device and drain pipe form and are slidingly matched, and the outer wall of drain pipe is pressed close in the outlet of liquid-inlet pipe.
Described floatation device is provided with through hole, and drain pipe passes described through hole.Described floatation device is ball float.
Adopt the present invention, 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, paint flow can be shunted by ball float when ball float, namely 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 invention will be further described below in conjunction with description of drawings and embodiment.
Description of drawings
Fig. 1 is the structural representation of existing coating material charging device.
Fig. 2 is structural representation of the present invention.
Among the figure 1 is liquid-inlet pipe; The 2nd, drain pipe; The 3rd, high liquid level sensor; The 4th, low liquid level sensor; 5 pressed gas entrances; The 6th, the container of splendid attire coating; The 7th, optical fiber coatings; The 8th, floatation device.
Embodiment
Referring to Fig. 2, optical fiber coatings tamping unit of the present invention comprises liquid-inlet pipe 1, drain pipe 2, and high liquid level sensor 3, low liquid level sensor 4, pressed gas entrance 5, the container 6 of splendid attire coating is installed on the floatation device 8 on the drain pipe 2.The outside of drain pipe 2 is pressed close in the outlet of liquid-inlet pipe 1, in the time of can flowing downward arrival floatation device 8 along the drain pipe outer wall after coating flows out from liquid-inlet pipe 1 mouth of pipe, 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 viscosity and the drop of coating itself, can leave certain distance between the outer wall of the outlet of liquid-inlet pipe 1 and drain pipe 2; Also can contact, but should leave enough spaces so that coating flows smoothly.
The floatation device of present embodiment is ball float, is provided with through hole in the ball float, forms with drain pipe 2 to be slidingly matched.Guaranteeing under the prerequisite of sliding smoothly, the external diameter of the internal diameter of ball float through hole and drain pipe 2 should approach as far as possible, the internal diameter of ball float through hole is slightly less than the external diameter of drain pipe 2, makes the gap between ball float and the drain pipe 2 enough little, avoids occurring the coating drop and passes the directly situation of drippage of excessive gap.
Specification sheets has clearly illustrated principle of the present invention and necessary technology details, and those of ordinary skill can be implemented fully.Interest field of the present invention is not limited to previous embodiment.
