A pulling device for optical fiber secondary coating

Abstract

The invention provides a traction device for secondary coating of an optical fiber. The traction device comprises a water tank, a traction wheel group and a water cooling device. The traction wheel group and the water cooling device are both arranged in the water tank. The water cooling device is arranged relative to the traction wheel group. The traction wheel group comprises a main traction wheel, an auxiliary traction wheel, a main traction wheel motor and an auxiliary traction wheel motor. The axis of the main traction wheel and the axis of the auxiliary traction wheel are located in different horizontal planes. The traction device meets the requirement on the high linear speed, and the length of the equipment water tank and the total length of equipment can be shortened greatly.

Description

technical field [0001] The invention belongs to the technical field of optical fiber production, and in particular relates to a pulling device for secondary coating of optical fiber. Background technique [0002] The secondary coating process of optical fiber is to select suitable polymer materials, adopt extrusion process, and under reasonable process conditions, put a suitable loose tube with the same length as the optical fiber on the optical fiber. At the same time, a mixture with long-term stable chemical and physical properties, suitable viscosity, excellent waterproof performance, long-term good protection performance for optical fibers, and fully compatible with the sleeve material is filled between the sleeve and the optical fiber, referred to as fiber paste. The optical fiber has free movement space in the tube, so the tensile and lateral pressure resistance of the optical fiber after the second coating is better. [0003] The formation mechanism of excess length:...

Problems solved by technology

At the same time, after increasing the length of the water tank, the distance between the casing and the water tank will become longer, and the resistance on the casing will be greatly increased, which will affect the stability of the remaining length.

[0005] In the traditional optical fiber secondary plastic traction, the main traction wheel shaft and the auxiliary traction wheel shaft are placed in parallel, and the bushing is not stable when transitioning between the wheels, and there is a phenomenon of jitter, resulting in easy fiber breakage or unstable excess length
