Spinning device for covering yarn

Abstract

The invention provides a spinning device for covering yarn, and belongs to the technical field of covering yarn. The spinning device comprises a yarn reversal mechanism, a drafting mechanism, a core-spun twisting mechanism and a winding yarn collectingmechanism; a collecting closing pipe of the yarn reversal mechanism is located below a core yarn guiding closing pipe and a covering yarn guiding assembly; the drafting mechanism comprises a back drafting assembly, a middle drafting assembly and a front drafting assembly, a first twisting gear and a second twisting gear of the core-spun twistingmechanism are meshed all the time, one end of a rocking bar is connected with a sliding driving motor, the other end of the rocking bar is hinged to one end of a connecting rod, the other end of the connecting rod is hinged to a rotating joint, a synchronous belt of a yarn collecting assembly of the winding yarn collecting mechanism surrounds a synchronous wheel and a driving wheel, and a drivinggear of the yarn collecting reciprocating guiding assembly is meshed with both a movable gear and a fixed gear. Spinning processing of covering yarn can be rapidly achieved, and the core-spun twistingstructure and the winding yarn collecting structure are reasonable in design.

Description

technical field [0001] The invention relates to the technical field of core-spun yarns, in particular to a spinning device for core-spun yarns. Background technique [0002] Core-spun yarn, also known as composite yarn or covered yarn, is a new type of yarn composed of two or more fibers. The original core-spun yarn is short fiber and short-fiber core-spun yarn developed with cotton fiber as the skin and polyester spun yarn as the core. Core-spun yarn is generally a yarn made of synthetic fiber filaments with good strength and elasticity as the core yarn, and short fibers such as cotton, wool, and viscose fibers are twisted and spun together. The core-spun yarn combines the excellent properties of the filament core yarn and the outer staple fiber. The more common core-spun yarn is polyester-cotton core-spun yarn, which uses polyester filament as the core yarn and is covered with cotton fibers. There is also spandex core-spun yarn, which is a yarn made of spandex filament ...

AI Technical Summary

Problems solved by technology

The core-spun twisting structure and the winding and receiving structure of the common spinning device at present are relatively complicated, not only the structure is huge, but also the cost is high
