Yarn ear forming mechanism of mule spinning machine

Abstract

The invention relates to a yarn ear shaping device of mule spinning machine, wherein it comprises: an information collecting treating system, a yarn guide arc transmitter, a spindle transmitter, a spindle cart, a tension arc, a feedback control circuit of spindle rotation, a servo motor control unit, and a yarn guide arc transmission feedback control circuit; the feedback control circuit of spindle rotation can shape the yarn better; the servo motor control unit can make the rotation speed of yarn guide arc supplied by servo motor meet the demand of yarn ear shape; the yarn guide arc transmission feedback control circuit can detect the transmission efficiency of whole yarn guide arc transmitter, to compensate the control signal sent from the servo driver to the servo motor in time, to meet the demand of rotation speed of yarn guide arc. And since it uses automatic control and feedback control yarn ear shaping device, the shape of yarn ear is better and accurate.

Description

technical field [0001] The invention relates to a yarn fringe forming mechanism of a mule spinning frame. Background technique [0002] Most of the yarn ear forming mechanisms on the existing mule spinning frames adopt mechanical forming mechanisms, such as cam forming mechanisms, forming rail forming mechanisms, and the like. According to the requirements of the spinning process, the characteristics of various wool yarns, and the needs of subsequent processing, the diameter, starting point, winding pitch, sector height, and yarn tension of the yarn spikes can be adjusted and controlled. However, the mechanical forming mechanism cannot meet the needs, and the parameter adjustment is not comprehensive and delicate enough. It can only roughly adjust the winding pitch and yarn tension; and the adjustment parameters are quite cumbersome and unpredictable. It takes several trials to get better forming. . And with the mechanical wear and tear, the forming error will become large...
