Electrically-driven self-adjusting pressure control method and device, program and storage medium

Abstract

The invention discloses an electrically-driven self-adjusting pressure control method and device, a program and a storage medium. The method comprises the following steps that position information of a cradle is obtained through a position sensor; a motor target torque is determined based on the position information of the cradle and a preset target contact pressure; the current torque of the motor is adjusted to be the target torque of the motor, so that a contact pressure between a production object and a production platform reaches the preset target contact pressure. According to the electrically-driven self-adjusting pressure control method and device, the program and the storage medium, the problems that a yarn contact pressure is inaccurate and spinning quality is unqualified due to the fact that production equipment is manually adjusted to control the yarn contact pressure are solved, the contact pressure borne by the production object is automatically and accurately adjusted according to requirements, manpower is saved, and the spinning production quality is guaranteed.

Description

technical field [0001] The invention relates to the field of automation control, in particular to an electric-driven self-regulating pressure control method, equipment, program and storage medium. Background technique [0002] In spinning forming, in order to control the yarn density, usually by adjusting the contact pressure of the yarn on the friction roller, the common contact pressure is to adjust the cradle (arm) where the yarn is located by mechanical devices such as springs. Pressure regulation, there are two common forms, the schematic diagram is as follows figure 1 and figure 2 . When the cradle is lifted to different angles, the tension of the spring is different, and then the contact pressure between the yarn roll at the end of the cradle and the friction roller can be adjusted. [0003] Due to the diversity of spinning varieties, different yarn process requirements are different, and the optimal yarn contact pressure required is also different. In the origina...
