Abstract

A device for a multi-stage carding rotor spinning method, including a spinning system and a computer control system. The spinning system includes a feeding and carding mechanism, a cohesive twisting mechanism, and a winding forming mechanism. It is characterized in that the feeding and carding The mechanism includes a combined cotton feeding roller with four degrees of freedom in rotation and a multi-stage opening roller. The speed ratio of the four rollers of the combined cotton feeding roller with four degrees of freedom in rotation is adjustable, which realizes random control of rotor spinning. Yarn linear density and blending ratio.

Description

technical field

[0001] The invention belongs to the field of rotor spinning in the textile industry Background technique

[0002] The basic principle of rotor spinning yarn is: the cotton sliver is held by the cotton feeding plate and the cotton feeding roller from the bell mouth, and the cotton feeding roller rotates and transports the cotton sliver to the carding area; the carding roller pair rotating at high speed in the carding area The sliver is opened, stripped, combed, separated, and mixed to make it into single fibers that are separated from each other and arranged in parallel and enter the cotton conveying channel; Under the action of the centrifugal force of the cup, the fibers are further superimposed and mixed in the condensation tank, drawn out from the parent yarn and twisted by the twister to form a yarn.

[0003] The patent "a method, device and product of rotor spinning mixed color yarn" (application number CN201410190891.1) and "a rotor spinning mixed colo...
