[0054] Sealing cylinder supporting part 5, this sealing cylinder supporting part 5 is positioned at the below that sends rod supporting part 3, and sealing cylinder supporting part 5 and sending rod supporting part 3 are slidably connected on the same guide rail 12. The below of sealing cylinder supporting part 5 is provided with sealing cylinder 4, sends rod 2 and seali...

Embodiment 2

[0062] see figure 2 , image 3 , Figure 4 and Figure 5 As shown, the embodiment of the present invention provides a common rail optical fiber drawing device. Compared with Embodiment 1, the difference between this embodiment is that the rod feeding beam tower 1 of this embodiment is preferably but not limited to a rectangular cross section. The steel frame structure, the specific cross-sectional structure of the rod beam tower 1 can also be selected by those skilled in the art as a triangular or regular polygonal structure. On the side walls parallel to each other on the bar beam tower 1, fix the guide rail 12 respectively, adopt the same mode as embodiment 1 to set the bar support part 3, the sealing cylinder support part 5, the bar bar 2, The sealing cylinder 3, the lifting mechanism and the high-temperature furnace 10 can realize that multiple optical fiber drawing production lines can be expanded on the rod feeding beam tower 1, and then realize the modular layout of...

Embodiment 3

[0064] see figure 2 , Figure 7 and Figure 9 As shown, the embodiment of the present invention provides a common rail optical fiber drawing device. Compared with Embodiment 1, the difference between this embodiment is that the rod feeding rod support part 3 of the embodiment of the present invention is provided with a rod feeding rod leveling structure 13. The rod feeding rod 2 is fixed on the rod feeding rod leveling structure 13, the rod feeding rod leveling structure 13 is connected with the rod feeding rod supporting part 3 by thread, and the rod feeding rod leveling structure 13 and the rod feeding rod supporting part are adjusted The relative position between 3 can adjust the setting position of the rod feeding rod 2, ensuring that the rod feeding rod 2, the sealing cylinder 4 and the high temperature furnace 10 are coaxial. The sealing cylinder support part 5 is provided with a sealing cylinder leveling structure 14, and the sealing cylinder 4 is fixed on the sealin...

Abstract

The invention discloses a common rail type optical fiber drawing device and a drawing method thereof, and belongs to the technical field of optical fiber production devices. The device comprises: a bar feeding beam tower, wherein a guide rail is fixedly arranged on the sidewall of the bar feeding beam tower, and the guide rail extends in the height direction of the bar feeding beam tower; a bar feeding rod supporting part, wherein a bar feeding rod is arranged below the bar feeding rod supporting part; a sealing cylinder supporting part located below the bar feeding rod supporting part, wherein the sealing cylinder supporting part and the bar feeding rod supporting part are connected to the same guide rail in a sliding mode, a sealing cylinder is arranged below the sealing cylinder supporting part, and the bar feeding rod and the sealing cylinder are coaxial; and a lifting mechanism arranged on the sidewall of the bar feeding beam tower and used for driving the bar feeding rod supporting part and the sealing cylinder supporting part to ascend and descend on the guide rail. The sealing cylinder and a sealing ring are adopted, so a clean sealing environment can be provided for wire drawing production, and the problem that impurities are adsorbed to the surface of an optical fiber preform is solved.

Description

technical field [0001] The invention relates to the technical field of optical fiber drawing preparation, in particular to a common rail optical fiber drawing device and a drawing method thereof. Background technique [0002] With the gradual deepening of information Internet construction, mobile communication has now entered the era of popularization of 4G communication, and the multi-dimensional big data market demand for the interconnection of everything and human-computer interaction has promoted the birth of 5G. As the carrier of information transmission, optical fiber will continue to increase in market demand in the construction of 4G and 5G, and the supply will exceed demand. The optical fiber drawing tower is the basic production equipment for the mass production of optical fibers from rods. In order to increase the production capacity of optical fibers, it will become particularly urgent to develop high-performance optical fiber drawing towers and to expand and tra...
