A kind of optical fiber coating and curing equipment and ultra-fine single crystal optical fiber containing mark

Abstract

The invention discloses an optical fiber coating and curing equipment and an ultra-fine single crystal optical fiber containing a mark, which comprises a fixing plate, the fixing plate includes a first vertical plate and a second vertical plate, and the second vertical plate is fixedly connected with an ink tank, and the ink tank is connected to the ink tank. The box is connected with a connecting block, the connecting block is provided with a first cavity, the spray gun is provided with a spray head, the two ends of the connecting block are provided with first wiring holes, a positioning block is fixed under the connecting block, and a second cavity is arranged in the positioning block , the second cavity is provided with a positioning column, the positioning column is provided with a second routing hole, the positioning block is connected with a return pipe, the return pipe is connected with the ink tank, the optical fiber enters the first cavity from the first routing hole, and the ink The ink is sprayed from the nozzle, and the ink is applied to the optical fiber to form a mark. Part of the unused ink is ejected from both sides of the optical fiber and flows into the first cavity, and the excess ink enters the second cavity from the first cavity. It is more convenient to recycle the excess unused ink, which is conducive to saving resources.

Description

technical field [0001] The invention relates to the field of optical fiber production, in particular to an optical fiber coating and curing equipment and an ultra-fine single crystal optical fiber containing a mark. Background technique [0002] Optical fiber is a relatively common light transmission tool that can be used to transmit analog and digital signals. Optical fibers are small in diameter and mechanically weak, and tend to break when subjected to abrasion. In the production process of the optical fiber, the surface of the optical fiber needs to be coated with paint to protect the surface of the optical fiber in order to enhance the mechanical strength of the optical fiber. At the same time, the optical fiber needs to be sprayed during production. Generally, an ink jet printer is used to coat and spray the optical fiber, and the optical fiber is sprayed with a logo, and then cured, so as to identify the batch and model of the optical fiber.
