Description

Technical Field

[0001] The utility model relates to a false twister, in particular to a double-guide-wheel false twister, which is mainly applied to organza spinning machines and belongs to one of the components of organza spinning machines. Background Art

[0002] Organza is processed from ordinary chemical fiber filaments by using the principle of false twisting and heat setting. The false twister is a key component for stretching and deforming chemical fiber filaments. Conventional stacked-disk false twisters and apron false twisters have high production efficiency, but the friction disks or aprons will damage the yarn, affecting the quality of the yarn.

[0003] Therefore, rotor false twisters have been introduced in the market at present. They cause no damage to the yarn, have stable and consistent twist, no dead silk generation, and can produce high-quality yarn, which can be used to manufacture high-grade and high-value-added clothing fabrics. However, the rotor false twisters in the prior art adopt a dragon belt drive and a swing-type tensioning, with complex twist line commutation. The diameter of the speed increasing wheel is about 34 mm, resulting in a small transmission ratio between the speed increasing wheel and the rotor component and a low rotational speed of the rotor component. To solve the above technical problems, the utility model patent with the publication number CN217077922U adds a clutch mechanism. However, those skilled in the art can simplify its clutch mechanism to further increase the rotational speed of the rotor component and improve the stability of the false twister.

[0004] The present utility model is thus produced. Content of the Utility Model
