Background

With the development of the optical fiber drawing technology in the high-speed and ultra-long distance direction, how to perform high-quality, long-time, stable and effective curing on the coated optical fiber becomes a key problem that restricts people to guarantee the optical fiber quality, improve the optical fiber drawing yield and reduce the optical fiber cost. The coating and curing technique of optical fibers is a very critical step in the fiber drawing process. Since the bare optical fiber is very vulnerable when directly exposed to the outside, it is necessary to apply a protective coating to the bare optical fiber and cure the coating during the preparation of the optical fiber. Meanwhile, through the coating and curing process, the mechanical property of the optical fiber can be greatly optimized, and the bending resistance of the optical fiber is enhanced, so that the overall performance of the optical fiber is comprehensively improved. The optical fiber curing process usually adopts an ultraviolet curing process, and an ultraviolet curing furnace is utilized to cure the protective coating on the outer surface of the optical fiber so as to form an optical fiber coating. If the optical fiber coating is cured badly, the optical fiber surface smoothness is poor, the optical fiber is sticky, the optical fiber curing degree is not enough, the lateral pressure resistance is not strong, and the subsequent processes are seriously influenced. For example, poor optical fiber rewinding is caused, the coloring of the optical fiber is influenced, and the residual stress of the optical fiber is seriously or even possibly too large, and the transmission performance of the optical fiber is influenced; furthermore, poor curing of the optical fiber coating can cause degradation of the mechanical properties of the optical fiber, and the optical fiber can break when the optical fiber is laid into an optical cable and the service life of the optical fiber is not over, thereby causing communication interruption.

But this application is only simple in the pipeline with optic fibre through leading to nitrogen gas, can't carry out effectual omnidirectional ultraviolet curing to utilize the mode of bleeding to replace gas, can't avoid outside dust by inside the pipeline of breathing in, and do not accomplish effectual dustproof measure in whole curing process.
