High-speed optical fiber drawing tower

Abstract

The invention discloses a high-speed optical fiber drawing tower which comprises a tower body framework. The tower body framework is provided with a plurality of symmetrically arranged screw holes, and the inner side of the tower body framework is sequentially provided with a high-precision feeding device, a high-temperature furnace, an annealing pipe, a bare fiber diameter detector, a cooling pipe, a coating system, a curing furnace, an eccentric detection system, a twisting device and a tension detection device from top to bottom; the tower body framework is fixed by using screws according to the requirements for different gradations, and a traction device and a double take-up device which are arranged in parallel with the tower body framework are arranged on the outer side of the tower body framework. The high-speed drawing tower has enough height, can achieve the maximum global drawing speed of 3,500 m / min, and can decrease the helium use amount of the optical fiber cooling pipe in the high-speed drawing process due to the advantages of the tower body in the production process by 5-8 L / min, and the optical fiber manufacturing cost is reduced while the drawing speed is increased.

Description

technical field [0001] The invention relates to optical fiber production technology, in particular to a high-speed optical fiber drawing tower. Background technique [0002] In the optical fiber manufacturing industry, the current general drawing tower height is 28m-33m, the maximum speed is 3000m / min, and the helium consumption of the cold tube is about 18-20L / min, which seriously restricts the optical fiber production capacity and the helium consumption is large, and the drawing speed is increased to One bottleneck is that helium is a strategic resource, and optical fiber production is completely imported, which virtually increases the cost of optical fiber manufacturing. [0003] In view of the above-mentioned defects, the designer actively researches and innovates in order to create a high-speed fiber drawing tower with a new structure, which can improve the fiber drawing efficiency, and at the same time increase the natural cooling time of the fiber through the advantag...
