[0002] Optical fiber is the abbreviation of optical fiber, which is a fiber made of glass or plastic that can be used as a light transmission tool. The transmission principle is the total reflection of light. Optical fiber is the core material of optical cable structure and is generally produced and manufactured using drawing dies. The quality of the drawing dies directly affects the processing accuracy, durability and wear resistance of the optical fiber, and plays an irreplaceable and important role in the optical fiber production process.

[0003] The existing drawing dies for optical fiber production have the following disadvantages when in use: the existing drawing dies are generally of an integral structure. Affected by their structure, changes in optical fiber specifications require replacement of the entire set of dies, which increases the cost of optical fiber production. Repeatability and concentricity are difficult to ensure, and the center cannot be fine-tuned online, making the operation cumbersome. Therefore, we propose a high-speed wet-to-wet improved online fine-tuning center coating die. Utility Model Content
