Abstract

The invention relates to an ultraviolet curing oven optical fiber coating curing assist device which is respectively provided with a gas seal device at an optical fiber entrance and an optical fiber exit of the ultraviolet curing oven. By a unique distributed gas pipe design, two ports of the ultraviolet curing oven form a vertical multiple gas seal structures, thus effectively reducing the air in the curing oven and precisely controlling the oxygen contents in the ultraviolet curing oven; the exit of the curing oven is provided with a smoke extraction device clinging to the curing oven, so as to effectively extracts the smoke and dusts through multiple gas extraction pipes, thereby effectively improving the curing quality of the optical fiber coating.

Description

technical field [0001] The invention relates to a production equipment in the process of drawing an optical fiber, in particular to an auxiliary device for curing an optical fiber coating by an ultraviolet curing furnace. Background technique [0002] In the optical fiber drawing process, the coating and curing technology of optical fiber is a very critical link. Since the bare optical fiber is very fragile when directly exposed to the outside world, it is necessary to coat the bare optical fiber with a protective coating and cure the coating during the preparation of the optical fiber. At the same time, through the coating and curing process, the mechanical properties of the optical fiber will be greatly optimized, the bending resistance of the optical fiber will be strengthened, and the overall performance of the optical fiber will be comprehensively improved. [0003] At present, the optical fiber coating technology mainly adopts two coating methods, that is, a soft inne...
