Abstract

The invention discloses single-wheel deflection optical fibre twisting equipment. An upper positioning wheel set (1), a single wheel deflection mechanism (2) and a lower positioning wheel set (3) are mounted on a machine frame (5) in sequence from top to bottom; through centering adjustment of the upper positioning wheel set (1) and the lower positioning wheel set (3), two guide wheel grooves of an upper positioning guide wheel (102) and a lower positioning guide wheel (302) are simultaneously tangent to the surface of an optical fibre (4); optical fibre twisting movement is transferred upwards stably; the continuity of periodic deflection movement is realized by the single wheel deflection mechanism (2) adopting a continuous transmission mechanism; by adopting a single-wheel periodic deflection structure, the two side surfaces of a V-shaped wheel groove are in contact with the optical fibre alternately, so that periodic reciprocating twisting of the optical fibre is realized; a motor of the transmission mechanism operates continuously in a single direction, so that forward and backward reciprocating movement is not required. The positioning guide wheels are added above and below the deflection wheel so as to ensure that the optical fibre is only twisted, and the swinging of the optical fibre is avoided. The equipment is easy, quick and convenient to machine, assemble and debug; the manufacturing and maintenance cost is remarkably reduced; technical requirements on an optical fibre drawing process can be met practically and effectively.

Description

technical field [0001] The invention relates to the technology of reducing optical fiber polarization mode dispersion PMD in the optical fiber manufacturing process, which belongs to the manufacturing and molding process of C03B glass, mineral or slag wool in the IPC classification, especially the structure improvement technology of optical fiber twisting equipment in the communication optical fiber drawing production line, especially It is a single-wheel deflection fiber twisting device. Background technique [0002] In the drawing process of optical fiber manufacturing technology, twisting is an effective means to reduce the PMD of optical fiber polarization mode dispersion. By rubbing the fiber in the forward and reverse directions, the fiber at the position above the softening temperature is periodically twisted in the forward and reverse directions, so that the fiber can maintain a certain number of twists per unit length after cooling, reducing the birefringence or In...
