Problems solved by technology

[0004] At present, the maximum speed of the domestic optical fiber secondary coating production line is stable at about 500m / min. When the speed of the optical fiber secondary coating production line is further increased, the problems of fiber breakage and unstable excess length frequently occur, which restricts the optical fiber secondary coating The overall speed of the plastic production line exceeds 500m / min, and the production quality is extremely unstable

Abstract

The invention discloses a traction device for secondary coating of high-speed optical fibers. The traction device comprises a traction wheel group, and the traction wheel group comprises a driving traction wheel, an auxiliary traction wheel, a traction motor and a servo motor; the driving traction wheel is arranged behind the auxiliary traction wheel relative to the direction of a production line,and connected to the traction motor; the auxiliary traction wheel is connected to the servo motor, and a towed casing pipe passes around the auxiliary traction wheel and the driving traction wheel successively; the driving traction wheel is driven by the traction motor so that the casing pipe is driven, and the auxiliary traction wheel is driven by the servo motor; and the stable tension of the optical fibers in the stress section, between the driving traction wheel and the auxiliary traction wheel, of the casing pipe is maintained. According to the traction device, the jitter of the casing pipe at high speed can be avoided, and the stable excess length of the optical fibers in the casing pipe is ensured; and the quality of the optical fibers after secondary coating is reliable, and the traction requirements for linear speed of 800 m / min or above can be met.

Description

technical field [0001] The invention belongs to the field of optical fiber and cable production, and more specifically relates to a pulling device for high-speed optical fiber secondary coating. Background technique [0002] The secondary coating process of the optical fiber is to select the appropriate polymer material and adopt the extrusion process to cover the optical fiber with a suitable loose tube that is equivalent to the length of 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 l...
