A Pneumatic Yarn Threading Two-for-One Twisting Spindle for Large Packages

Abstract

The invention discloses a large package pneumatic yarn passing two-for-one twisting spindle, and belongs to the field of a spindle of a two-for-one twister. The large package pneumatic yarn passing two-for-one twisting spindle comprises a tension pipe component and a lining spindle component, wherein an upper tension capsule is arranged between a tension regulator and an upper guide wire combination pipe arranged in an upper tension pipe of the lining spindle component; the upper tension capsule and two first-stage brake rings are matched for forming a brake structure; the tension pipe component is connected with the upper guide wire combination pipe of the upper tension pipe through a guide wire connecting pipe; a lower tension capsule is arranged between the guide wire connecting pipe and a lower guide wire combination pipe arranged in a lower tension pipe of the tension pipe component; the lower tension capsule and two two-stage brake rings form a brake structure. The large package pneumatic yarn passing two-for-one twisting spindle has the advantages that the pneumatic yarn passing of the large package two-for-one twisting spindle is realized; the four tension application points are provided; the requirements on the yarn tension magnitude and the uniformity during the large package of the yarns can be met; the yarn tension is adjustable.

Description

technical field [0001] The invention belongs to the field of two-for-one twisting machine spindles, and more specifically relates to a two-for-one twisting spindle for large package pneumatic threading. Background technique [0002] The spindle is one of the main components of the twisting and winding on the two-for-one twister, and it is an assembly with a slender rotating shaft supported by two points as the main body. At present, there are two types of spindles for two-for-one twisters: ordinary spindles and pneumatic yarn threading spindles. The advantage of pneumatic spindles is that they are convenient and fast to thread yarns. The efficiency of threading operation is about 5 to 10 times that of ordinary spindles, which can reduce the labor intensity of the locomotive workers. , Improve the operating rate of the two-for-one twister. [0003] Existing two-for-one twisting spindle realizes threading of yarn by means of compressed air and threading injector. Compressed ...
