Method for adjusting lifting speed ratio of steel plate of spinning machine

The invention relates to a method for adjusting lifting speed ratio of a steel plate of a spinning machine. The method comprises a signal input step: inputting a variable for controlling the lifting speed of the steel plate on a human-machine interface; a signal sending step: sending a pulse matched with the speed and displacement of a servo motor by a controller according to the transmission ratio of lifting speed to displacement variable of the servo motor and the steel plate; a signal converting step: converting the received pulse sent by the controller into a voltage signal by a servo motor driver; a servo motor driving step: controlling the running speed of the steel plate by the servo motor according to the received voltage signal, thereby achieving the effect of quickly ascending and slowly descending the steel plate. According to the method for adjusting the lifting speed ratio of the steel plate of the spinning machine, provided by the invention, the broken yarns in the spinning process are reduced,
