Abstract

The invention discloses an optical fiber drawing coating device, which comprises a mounting plate, a coating mechanism, a bubble treatment mechanism, a cooling mechanism, and a curing mechanism. The mounting plate is provided with a cooling mechanism, a coating Covering mechanism, bubble processing mechanism and curing mechanism, the bubble processing mechanism and curing mechanism are located on the same horizontal plane, the bubble processing mechanism performs gas removal treatment on the paint containing bubbles, and the upper end of the cooling mechanism is connected to the lower end of the wire drawing furnace. The coating mechanism coats the bare fiber with paint and recycles the excess paint. The air bubble treatment mechanism makes the paint be thrown out of the drum through centrifugal force, and the paint is divided into multiple parts during the movement process, so that The paint hits the inner wall of the negative pressure box with the smallest volume, so that the air bubbles in the paint are broken, and the air bubbles in the paint are removed.

Description

technical field [0001] The invention relates to the technical field of optical fiber drawing and coating, in particular to an optical fiber drawing and coating device. Background technique [0002] In the process of optical fiber drawing, in order to protect the surface of the glass optical fiber, it is necessary to coat the surface of the optical fiber with multi-layer coating, which is usually done by coating the optical fiber coating. The optical fiber coating is usually made of polymer resin compound material, which is liquid at room temperature. [0003] During the coating process, if there are bubbles in the coating, it will have an impact on the quality of the optical fiber surface. Therefore, the coating device must remove the coating with bubbles before the optical fiber is produced. At present, it is basically manual operation to remove the coating at the front end of the coating device until there are no air bubbles. Moreover, the removed coatings cannot be recyc...
