Embodiment Construction

[0078] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0079] see Figure 1 to Figure 2 , in this embodiment, a torque balance control method for a circular knitting machine can be applied to a storage device, the storage device can be a circular knitting machine, and the circular knitting machine includes: a master motor and a slave motor, as follows Expand the specific description:

[0080] Step S101: The main motor adopts a position control mode, and the position loop, speed loop and current loop of the main motor are subjected to three-loop closed control.

[0081] Step S102: The slave motor adopts the torque control mode. That is, the slave motor only includes a current loop.

[0082] Step S103: The output of the speed loop of the master motor is used as the current given amount o...

Abstract

The invention relates to the technical field of knitting machines, in particular to a torque balance control method and system for an annular knitting machine and storage equipment. The torque balance control method for the annular knitting machine comprises the following steps: a main motor adopts a position control mode, and a position ring, a speed ring and a current ring of the main motor are subjected to three-ring closed control; a slave motor adopts a torque control mode; and the output of the speed loop of the main motor is used as the current given quantity of the current loop of the slave motor. By means of the method, torque balance control and rotation speed synchronization of the motors can be achieved, stable operation of the knitting machine is guaranteed, and fabric quality and production efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of knitting machines, in particular to a torque balance control method, system and storage device of an endless knitting machine. Background technique [0002] The number of gears, dials and yarn carriers of the circular knitting machine is large, and the driving power requirement is large. Synchronous driving of multiple servo motors is required to meet the demand for uninterrupted movement. The motors on the braided ring are connected through hard shafts of gears, so as to achieve the purpose of forced synchronization of speed. However, due to the existence of problems such as different meshing stiffness, manufacturing errors and tooth side clearances in the gear transmission system, it is easy to cause the load on each motor to The torque is different, and the operation of the knitting machine is stuck, which seriously affects the knitting quality and production efficiency.
