Problems solved by technology
Most of the existing raising machines in China use frequency converters to drive motors, open-loop speed control systems for cylinders, raising rollers, and cloth guide rollers. This control system also has many other factors that affect speed changes, such as: changes in the elasticity of various fabrics 1. The change of fabric tension during fluffing, the change of fluffing force, the change of power supply voltage, the change of AC motor load, and the change of the tension of needle roller drive V-belt make the fluffing force control unstable and affect the improvement of textile product grade.

The invention discloses a real-time control system and a control method for a napping force of a napping machine by a multi-axle drive, wherein the real-time control system comprises a PLC(Programmbale Logic Controller), a spreading roller transducer, a cylinder transducer, a clockwise porcupine roller transducer, an anticlockwise porcupine roller transducer, a front guide roller transducer, a back guide roller transducer and a draw-out roller transducer, and a real-time velocity-measuring system is also arranged. The real-time velocity-measuring system comprises a cylinder velocity-measuring sensor, a clockwise porcupine roller velocity-measuring sensor, an anticlockwise porcupine roller velocity-measuring sensor, a front guide roller velocity-measuring sensor, and a back guide roller velocity-measuring sensor; the real-time velocity-measuring system is connected with a high-speed counter input port of the PLC; each transducer is connected with the PLC through an RS485 serial port communication line; the PLC can synchronously visit each transducer to guarantee a collaborative operation of each motor. Due to adoption of the real-time control system, so that a constant rotary speed of fabrics in a napping process is guaranteed, namely, a constant napping force is controlled, and the real-time control system has the advantages of simple structure, high control precision and low failure rate.
Description
technical field [0001] The invention relates to a control system and a control method of a raising machine, in particular to a real-time control system and a control method of the raising force of the multi-axis transmission of the raising machine. Background technique [0002] Raising machine, mainly suitable for raising cotton, blended fabrics and knitted fabrics. The development of raising machines has only a few decades of history. Some high-end raising machines mainly in Germany and Italy were born in the 1980s, and the research and development of domestic high-end raising machines began in the early 21st century. At present, the development of raising machines at home and abroad The general trend is environmental protection, green, energy saving, low consumption, high efficiency and intelligence. [0003] The raising force of the raising machine refers to the interaction force between the fabric and the raising needle roller (including clock raising roller and counter...
