Title: ROTOR SPINNING METHOD AND DEVICE FOR FOUR-SLIVER ASYNCHRONOUS INPUTTING AND THREE-LEVEL CARDING
Abstract:
A multi-level carding rotor spinning method and device. The device comprises a spinning system and a computer control system. The spinning system comprises a feeding and carding mechanism, a condensation and twisting mechanism, and a winding and molding mechanism. The feeding and carding mechanism comprises combined cotton feeding rollers (2-5, 2-6, 2-7, 2-8) at four rotation freedom degrees and multiple levels of carding rollers (2-10, 2-11, 2-12). The speed ratio of four rollers of the combined cotton feeding rollers at four rotation freedom degrees can be adjusted, so that the linear density and the blending ratio of rotor spun yarns are randomly adjusted.
