Drafting mechanism of spinning machine

Abstract

The invention discloses a drafting mechanism of a spinning machine. The drafting mechanism of the spinning machine comprises a first drafting assembly, a second drafting assembly and a cradle positioned between the two drafting assemblies, wherein each drafting assembly comprises a leather roller and a roller positioned below the leather roller; a gap allowing the entrance of coarse yarns is formed between each leather roller and the corresponding roller; each leather roller and the corresponding roller are looped by a clamping band, and two ends of the clamping band are fastened cooperatively through a clamping hole and a bulge. According to the drafting mechanism of the spinning machine, the vertical gap between each leather roller and the corresponding roller can be freely adjusted, the problem of non-tight engagement of the leather roller and the roller caused by long-term use of a leather ring is solved, the service life of the leather ring is prolonged, and the drafting mechanism of the spinning machine is simple in structure and easy to produce.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a drafting mechanism for spinning frames. Background technique [0002] The spinning frame is a link in the whole textile process. Its task is to process the roving spun by the roving frame into spun yarn, that is, the drafting device in the spinning frame must provide sufficient draft force during the processing, so that the spun yarn The sliver is more uniform. However, the traditional stretching top rollers are directly smaller, need to provide a larger drafting force, require higher energy consumption, high bearing loss, and a shorter wear cycle of the top rollers. [0003] At the same time, due to the long-term high pressure on the apron, it is easy to appear that the top roller and the roller are not tightly cohesive, which has a certain impact on the uniformity of the additional friction force circle in the drafting process, resulting in the apron opening and un...

AI Technical Summary

Problems solved by technology

However, the traditional stretching top rollers are relatively small and need to provide a large draft force, which requires high energy consumption, high bearing loss, and short wear cycle of the top rollers.

[0003] At the same time, due to the long-term high pressure on the apron, it is easy to appear that the top roller and the roller are not tightly cohesive, which has a certain impact on the uniformity of the additional friction force circle in the drafting process, resulting in the apron opening and unevenness. and so on
