CN201950004U - Device for filling optical fiber paint - Google Patents

Abstract

The utility model relates to a device for filling optical fiber pain, which relates to the manufacturing technical field of the optical fiber. The device comprises a liquid inlet pipe and a liquid outlet pipe, and is characterized in that: the end of the liquid outlet pipe is bent, and the end of the liquid outlet pipe is bent towards the direction which is away from the liquid inlet pipe. Due to adoption of the device, the discharging time of bubbles which are mixed inside the paint can be prolonged. Since the production area of the bubbles is away from the pipe orifice of the liquid outlet pipe, when the paint of the bubble production area flows by the pipe orifice of the liquid outlet pipe, a majority of bubbles floats upwards and disappears, thereby the influence of the bubbles on the optical fiber can be reduced during the coating.

Description

A kind of device of filling optical fiber coatings

Technical field

The utility model relates to the optic fibre manufacturing technology field.

Background technology

Referring to Fig. 1.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 through some row components and parts such as pipeline valves, is pressed to main jar feed tube by air pressure, the 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, after filling liquid reaches high liquid level sensor, fill and stop.A main jar feed tube that adopts in the optical fiber industry at present is a straight tube, when filling, 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, the intensity and the coating quality of optical fiber caused damage from drain pipe.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 not have the zone that applies, 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 surrounding air produces into and follow coating and be coated in problem on the optical fiber through drain pipe through main jar of feed tube.

The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: a kind of device of filling optical fiber coatings, comprise feed tube, and drain pipe is characterized in that, the terminal bending of drain pipe, and bending direction is away from feed tube.

Feed tube is on the plane of crooked drain pipe formation.

The utility model can increase the bubble discharging of sneaking in the coating, because the generation zone of bubble is away from the drain pipe nozzle position, so when the coating in bubble generation zone flow through the fluid mouth of pipe, bubble floated in a large number and disappears, bubble is to the influence of optical fiber in the time of so can reducing coating.

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 the structural representation of the utility model optical fiber coatings filling device.

Among the figure, the 1st, 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 specific embodiment

Referring to Fig. 2, light coating material charging device of the present utility model comprises feed tube 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, drain pipe 2 is terminal crooked, bending direction is away from feed tube 1, and promptly the vertical section with drain pipe 2 is a center line, and the end of drain pipe 2 points to the offside of feed tube 1.

During filling paint, optical fiber coatings flows down the bubble that produces in the process can have adequate time come-up and disappearance at the coating that has bubble away from the mouth of pipe of drain pipe 2 in drain pipe 2 mouth of pipe process of flowing.So can reach and reduce the number of bubbles that is blended in the drain pipe 2 in the coating.

Claims (2)

1. a device of filling optical fiber coatings comprises feed tube (1) and drain pipe (2), it is characterized in that, and the terminal bending of drain pipe (2), and bending direction is away from feed tube (1).

2. the device of filling optical fiber coatings as claimed in claim 1 is characterized in that, feed tube (1) is on the plane of crooked drain pipe (2) formation.
