Cleaning method for optical fiber coloring device and optical fiber coloring device

摘要

An ink pool is formed between the nipple, the first die, the second die, and the outer periphery of the nipple that sequentially pass through the optical fiber, and a frame having an ink supply port and a cleaning liquid discharge port connected to the ink pool. An ink flow path is formed between the nipple, the first die, and the second die, and the optical fiber passage hole of the second die has a tapered portion whose inner diameter decreases in the direction of passage of the optical fiber. A cleaning method for an optical fiber coloring device having a first cleaning step of supplying a cleaning liquid from an optical fiber passage hole and an ink supply port of a nipple and discharging from the cleaning liquid discharge port, an optical fiber passage hole of the nipple and an ink A second cleaning step of supplying a cleaning liquid from the supply port and discharging the cleaning liquid from the optical fiber passage hole of the second die. Thus, a cleaning method and a coloring device for an optical fiber coloring device capable of improving the productivity of the optical fiber and reducing the manufacturing cost are provided.
