Abstract

The invention relates to a roller control system of a rotor spinning machine and belongs to the technical field of textile machinery. The roller control system comprises a controller and a stepping motor. The stepping motor drives a roller to rotate. The controller controls the stepping motor to operate. The front end of the shaft of the stepping motor is in transmission connection with a roller shaft and drives the roller shaft to rotate. The rear end of the shaft of the stepping motor axially extends out of the shell of the stepping motor to form an extension shaft. A speed measuring device is mounted on the extension shaft. The speed measuring device is in signal connection with the controller. The control program of the controller is provided with a speed comparison module and a speed regulating module. By the roller control system, the problem that yarn quality and machine operation efficiency are affected due to the fact that the rotation speed of the stepping motor and the roller of an existing rotor spinning machine cannot be fed back timely is solved, spindle position roller speed deviation change is reduced, and rotor spinning machine operation efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and in particular relates to a roller control system of a rotor spinning machine. Background technique [0002] In the rotor spinning machine, the fed fiber slivers are opened into single fibers by the rotary carding roller covered with card clothing, and are transported to the inner wall of the high-speed rotating rotor along with the airflow, and the yarn tail is formed in the condensation groove. The twisted yarn is drawn out and directly wound into a bobbin. Most of the rollers of the current rotor spinning machine are driven by stepping motors. The driving mode of ordinary stepping motors belongs to open-loop control. The controller does not know the current speed and position of the stepping motor. If the stepping motor appears Problems, such as out-of-step, stalled, etc., the controller cannot obtain the current running speed of the stepping motor and the roller in time, which...
