In the existing solution, the discharge port of main jar of interior filling tube can be pressed close to carrier pipe, and coating material is flow in main jar along the tube wall of extraction line.But in actual production process, discharge port can not remain the state pressed close to carrier pipe.Because the interference discharge port of Externality can be once in a while away from carrier pipe, at this moment, coating material can get into master's jar from the discharge port drippage, and the coating material that drips main jar can be brought new gas in original coating material, and then coating impacts to optical fiber.
The utility model content
In view of this; The utility model provides a kind of optical fiber coating unit that reduces the fibre coating bubble; Solution is being added in the process of coating material to main jar by auxilliary jar, because coating material drips from the mouth of pipe, and in main jar, produces the problem of new bubble in original coating material.
For solving above technical problem, the technical scheme of the utility model is a kind of optical fiber coating unit that reduces the fibre coating bubble; Comprise main jar; Main jar is inserted with two conduits through the jar mouth, is respectively filling tube and carrier pipe, and the feeding mouth that the discharge port of main ladle addition pipe is higher than high liquid level (HLL), carrier pipe is lower than minimum level; Said filling tube is near carrier pipe; The discharge port of filling tube is pressed close to the tube wall of carrier pipe, and said filling tube and/or carrier pipe are provided with rake, and coating material adds when becoming owner of jar and flows in main jar along corresponding tube wall through rake.
Said rake is arranged on the filling tube, and the angle of bend of this rake is the obtuse angle, and the summit of said angle of bend is higher than the high liquid level (HLL) of coating material, makes coating material flow into main jar along the tube wall of carrier pipe.
Also be provided with rake on the said carrier pipe, this rake is located on the tube wall near discharge port, makes coating material flow into main jar along the tube wall of carrier pipe.
Said rake is arranged on the filling tube, and the angle of bend of this rake is an acute angle, and the summit of said angle of bend is lower than the minimum level of coating material, makes coating material flow into main jar along the tube wall of filling tube.
Form the gap between said discharge port and the carrier pipe tube wall, this gap is 1mm ± 0.5mm.
Said discharge port is the wedge shape that opening makes progress.
Said carrier pipe is being provided with drainage trough near the discharge port place.
Compared with prior art; The utility model is because filling tube and/or carrier pipe are provided with rake; Institute, has avoided in main jar, producing new bubble because of the coating material drippage so that coating material can slowly flow in main jar along corresponding tube wall all the time when discharging original gas; Finally reach and reduce the purpose that gas gets into main jar coating material, and then improve the coating quality of optical fiber.
