Device and method for covering yarn

Abstract

The invention relates to a device for covering yarn, which comprises an unwinding device, a twisting device, a drafting device and a winding device, at least one number-one rotary plate is arranged below a number-two rotary plate, the number-two rotary plate is arranged above an axis line in the number-one rotary plate by a driven shaft, a driving shaft is arranged below the axis line in the number-one rotary plate, the number-one rotary plate is internally provided with an intermediate shaft and a balancing shaft which are parallel to the driving shaft respectively at the two sides of a shaft driving the number-two rotary plate, a tangential belt drives the driving shaft which is provided with a driving belt wheel, the driving belt wheel transmits a first intermediate belt wheel below the intermediate shaft by the belt wheel, a second intermediate belt wheel above the intermediate shaft drives the driven shaft, the driven shaft drives the number-two rotary plate to rotate, and the driving shaft drives the number-one rotary plate to rotate. The device utilizes the transmission ratio of the belt wheel to enhance the shaft rotational speed, has simple structure, is improved based on the original mechanical yarn covering machine, enhances the production efficiency, adopts the shape of a single cone in packaging outer yarn, reduces the original winding procedure and reduces the production cost.

Description

technical field [0001] The invention belongs to the field of manufacturing textile covered yarns, in particular to a device and method for covered yarns. Background technique [0002] Covered yarn has obvious advantages in terms of raw material applicability, yarn forming performance, and final product style, and has great development prospects. Among them, spandex covered yarn combines the good elasticity of spandex with other characteristics of the covered yarn to form a spiral shape. The composite yarn is formed by covering the stretched elastic yarn, and its application range is more and more extensive. [0003] There are currently two types of spandex covered yarn, one is mechanically covered yarn using hollow spindle twisting process, the other is air covered yarn twisted using network nozzle, due to the surface of air covered yarn produced There is hairiness, which limits its use in the hosiery industry, while the surface of the clothes woven by mechanically covered ...
