Traditional mechanical twisting machine
Due to the limitations of traditional mechanical forming in terms of speed, forming effect and maintenance, many spinning machine manufacturing companies have devoted themselves to the research and development of electronic forming and twisting machines in recent years. However, due to limitations in molding control accuracy, anti-folding algorithms and other issues, the actual equipment put on the market is not yet very mature. The servo forming electrical control system of Sanacer products has been sold in large quantities on the market and has achieved good economic and social benefits.
Traditional twisting machines only use one motor as power, which is distributed to the spindle, winding shaft and transverse swing rod through a tangential transmission mechanism and a gear mechanism. Mainly mechanical transmission, sturdy and durable, with relatively low technical threshold, are the main features of traditional twisting machines.
Double twisting machine in the electric era
With the development of control technology, purely mechanical transmission systems can be replaced by multi-motor transmission systems to achieve optimization of machinery and applications. The continuous development of modern electrical control technology can achieve:
The three-phase induction motor is driven by a frequency converter to achieve stepless speed regulation and can be used to control the spindle speed and winding speed. The spindle speed and winding speed are separately controlled, making it easy to control the yarn twist, and the winding speed can be infinitely adjusted, which is more conducive to controlling power consumption.
The permanent magnet synchronous servo motor is equipped with a high-precision encoder and is controlled by a servo driver to achieve fast start and stop and high-precision positioning, and can be used to control the horizontal swing bar. The servo-controlled horizontal swing bar can adjust the yarn angle and winding action arbitrarily, and can also control the yarn accumulation into a specific shape to meet the requirements of subsequent processing.
