Knitting machine and control method thereof

Abstract

The invention provides a knitting machine and a control method thereof. The knitting machine comprises a roller motor and a master control system. The master control system comprises a judging moduleand an instruction module. The judging module comprises a status detection module for detecting status of the knitting machine. The instruction module is used for sending a speed instruction and a torque instruction to the roller motor. The instruction module and the judging module are in electric connection, the speed instruction controls the roller motor to switch into a speed mode, and the torque instruction controls the roller motor to switch into a torque mode.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a knitting machine and a control method thereof. Background technique [0002] After the fabric of the knitting machine is compiled by the knitting mechanism, the fabric is pulled out from the knitting area by a cloth rolling motor and a roller motor on the market. The roller motor clamps the fabric from the weaving area and pulls it downward, and the fabric rolling motor curls the fabric pulled down by the roller motor. Existing fabric winding motors and roller motors are generally controlled by single-phase torque motors. When the torque motor is less than the set torque, the motor is running. When the torque motor is greater than the set torque, the motor stops. [0003] However, using this single-phase torque mode will have the following disadvantages. First of all, when the machine has rags in the weaving area, the roller motor may still be running, which will cause the g...

AI Technical Summary

Problems solved by technology

First of all, when the machine has rags in the weaving area, but the roller motor may still be running, it will cause the gap in the rags to increase continuously, and cause the cloth to fall

Secondly, when the machine breaks down or the on-site workers need to adjust the machine, it is often necessary to unwind or unload the knitting machine, but if the roller motor is controlled by a torque motor, it will not be possible to accurately control the displacement of the unloading or unloading

Furthermore, in order to avoid the situation where the rag gap is constantly increasing, when the rag causes a shutdown, the on-site workers will turn off the torque motor (that is, the voltage of the control motor is 0V), which will cause the fabric to return
