Single-spindle yarn guide mechanism of rotor spinning machine

Abstract

The invention relates to a single-spindle yarn guide mechanism of a rotor spinning machine. Each spindle has a set of the single-spindle yarn guide mechanism. The single-spindle yarn guide mechanism comprises a yarn guide motor base, a spacer bush, a yarn guide motor, a yarn guide roller, an electric control box, a main beam and a leather roller; the yarn guide motor base is fixedly arranged on the main beam; the yarn guide motor is arranged on the yarn guide motor base; the yarn guide roller is connected with the yarn guide motor; the spacer bush is arranged between the yarn guide motor and the yarn guide roller; the electric control box and the yarn guide motor are connected and in driving control; the yarn guide roller is contacted with the leather roller; one end of a spring is arranged on the leather roller; and the leather roller is contacted with the yarn guide roller through a spring. According to the single-spindle yarn guide mechanism of rotor spinning machine in the invention, each spindle has a set of the single-spindle yarn guide mechanism; installation and debugging are convenient; because of single-spindle transmission, the load of the motor is small; the running precision of the motor is high; back and forward rotation angles of the yarn guide roller can be precisely controlled; therefore, the back and forward rotation length of yarns can be precisely controlled; and the precision and the reliability of yarn guiding, splicing, collective tailing and collective starting actions can be improved.

Description

technical field [0001] The invention belongs to the technical field of rotor spinning machines, and in particular relates to a yarn guiding mechanism for a single spindle of a rotor spinning machine. Background technique [0002] When the semi-automatic rotor spinning machine is spinning, the yarn delivery roller, which is composed of the yarn delivery roller and the yarn delivery rod touching each other, clamps and pulls the condensed and twisted yarn in the rotor out of the spinner, and then the winding roller The yarn bobbin is driven to clamp the winding yarn, and the yarn delivery roller is driven by the yarn delivery rod which is always in a rotating state to drive the yarn delivery cot to rotate simultaneously to clamp and draw the yarn. When yarn breakage occurs, the yarn will be detached from the yarn delivery roller after being continuously wound. The single-spindle yarn guiding mechanism of the existing rotor spinning machine adopts the single-side whole vehicle ...
