Abstract

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, various indexes of the yarns are promoted and the coil slippage phenomenon under a uncoiling state can be effectively relieved and prevented in the manner of adjusting the ascending and descending speeds of the steel plate.

Description

technical field [0001] The invention belongs to the field of spinning frames, and in particular relates to a method for adjusting the lifting speed ratio of ring plates of spinning frames. Background technique [0002] At present, in terms of the transmission of the ring plate in the domestic spinning frame, the servo motor has been controlled by PLC for transmission, replacing the original mechanical cam transmission. However, due to the influence of traditional spinning process requirements, the ring bars all rise slowly and fall quickly. This action mode can no longer meet the requirements of all spinning varieties, and there will be frequent end breaks, and loop stripping during unwinding. Contents of the invention [0003] In view of this, the object of the present invention is to provide a method for adjusting the lifting speed ratio of the ring bar of the spinning frame, aiming at overcoming the defect that the ring bar speed of the traditional spinning frame canno...
