Flat yarn straightening mechanism for manufacturing guide needles

Abstract

The invention relates to a flat yarn straightening mechanism for manufacturing guide needles. The flat yarn straightening mechanism includes a thickness direction straightening part, a fixing plate and a width direction straightening part, the thickness direction straightening part and the width direction straightening part are installed on the fixing plate, the thickness direction straightening part includes a first thickness straightening roller set and a second thickness straightening roller set, and the first thickness straightening roller set and the second thickness straightening rollerset are cooperated with each other to form a thickness direction straightening path which can adjust the inclination and spacing in the middle; and the width direction straightening part includes a first width straightening roller set and a second width straightening roller set, the first width straightening roller set and the second width straightening roller set are cooperated with each other toform a width direction straightening path which can adjust the inclination and spacing in the middle, and the thickness direction straightening path and the width direction straightening path has thesame extension direction and the corresponding position in the extension direction. According to the flat yarn straightening mechanism for manufacturing the guide needles, the straightness of flat yarns in the directions of thickness and width can be straightened, and the shape quality of flat yarns is improved.

Description

technical field [0001] The invention belongs to the technical field of flat yarn straightening, in particular to a flat yarn straightening mechanism for manufacturing yarn guide needles. Background technique [0002] With the rapid development of the knitting industry, the demand of the knitting market is increasing day by day. Yarn guide needle is a key component of high-speed warp knitting machine, its quality not only affects the quality of knitted products, but also affects the production efficiency of knitted products. [0003] Flat yarn is an approximately rectangular steel strip with a small cross-sectional area, and is the raw material for manufacturing warp knitting machine guide needle blanks. However, during the rolling, heat treatment, twisting and transportation of flat wire, due to the influence of external force, temperature change and internal residual stress, etc., the raw material of flat wire will undergo plastic deformation such as bending and torsion to...
