Yarn collecting device for core spun yarns in different types

Abstract

The invention belongs to the technical field of core spun yarns and provides a yarn collecting device for core spun yarns in different types. The yarn collecting device comprises a yarn unwinding mechanism, a yarn guide mechanism and a yarn collecting mechanism. The yarn unwinding mechanism comprises more than two yarn unwinding components, the lower end of a first front swing rod of a front tension adjustment driving portion of the yarn guide mechanism is fixed to a first front gear, the lower end of a second front swing rod is fixed to a second front gear, the lower end of a first rear swingrod of a rear tension adjustment driving portion is fixed to a first rear gear, and the lower end of a second rear swing rod is fixed to a second rear gear. A first tension adjustment roller is rotationally arranged at upper ends of the first front swing rod and the first rear swing rod, and a second tension adjustment roller is rotationally arranged at upper ends of the second front swing rod and the second rear swing rod. A driving gear of a yarn collecting guide component of the yarn collecting mechanism is rotationally arranged on a gear supporting seat and meshed with a fixed rack and amoving rack. The yarn collecting device is adjustable in yarn collecting force and applicable to collecting of the core spun yarns in different types.

Description

technical field [0001] The invention relates to the technical field of core-spun yarns, in particular to a yarn receiving device that can be used for different types of 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,...

AI Technical Summary

Problems solved by technology

Yarn receiving is the process of evenly winding the yarn on the yarn disk to the bobbin. The core-spun yarn is a new type of yarn composed of two or more fibers. During the yarn receiving process, different Different fibers have different requirements on the yarn receiving tension. The yarn receiving tension of the common yarn receiving device cannot be adjusted during the yarn receiving process.
