Processing device for yarn wrapping

Abstract

The invention discloses a processing device for yarn wrapping. The device comprises a rack, a feeding roller, a drafting roller, a rotation shaft, a rotation disk, a supporting disk, a protective cover and a tensioner, wherein a core yarn coiling drum is disposed on the supporting disk and located in the protective cover; core yarns pass through the tensioner and then penetrates a third yarn guide hole; outer wrapping yarns pass through the feeding roller, then successively pass the center hole of the rotation shaft, a first yarn guide hole and second yarn guide hole and finally wrap the core yarns at the third yarn guide hole; and the wrapped yarns formed after wrapping are drafted by the drafting roller. Through application of the invention, quality of the wrapped yarns is increased, and continuous production is promoted.

Description

Technical field [0001] The invention relates to the field of spinning devices; specifically, the invention relates to a processing device for wrapping yarn. Background technique [0002] Wrapped yarn is a kind of yarn (wrapped yarn) wrapped on another yarn (core yarn) in the yarn forming process to make a special structure of yarn. The wrapping yarn wraps the core yarn in a spiral manner. Wrapping yarns are mostly used for knitted fabrics that require high elasticity, and some are used for woven fabrics. They are ideal yarns for high-grade thin wool, linen fabrics, jacquard double-layer weft knitted fabrics and warp knitted fabrics. [0003] Chinese patent document CN104652004A discloses a covered yarn processing equipment with stable spindle speed. The equipment includes a hollow spindle, a double-sided bobbin is installed above the hollow spindle, and a dragon belt is installed below the hollow spindle. Above the pre-draft roller, a balloon guide wire hook is installed above th...

AI Technical Summary

Problems solved by technology

[0004] This kind of wrapping method, because the hollow spindle needs to drive the double-sided bobbins to rotate, the load is relatively large, the energy consumption is high, and the rotation speed is restricted to a certain extent.

And before the wrapping action, the outsourcing yarn needs to be wound onto the double-sided bobbin dedicated to the hollow spindle spinning machine through the winding machine. After winding, the outsourcing yarn bobbin has less yarn, and it needs to be knotted to form knots after each replacement. Resulting in low quality wrapped yarn

In addition, in the traditional wrapping method, the length of the wrapping yarn is limited, and it may be necessary to replace multiple wrapping yarn barrels to complete one wrapping yarn, making it difficult to achieve continuous wrapping processing
