Ring spinning frames are undergoing a profound transformation from "manufacturing" to "intelligent manufacturing." INVT has launched an all-electric control system for ring spinning frames, enabling rapid process adjustment and real-time monitoring functions, reducing manual intervention, and enhancing production flexibility.
Process adjustments require frequent gear changes, which are time-consuming and labor-intensive, making it difficult to adapt to small-batch, multi-variety orders.
Power outages or voltage sags can easily lead to entire machine yarn breakage, increasing the labor intensity of doffers for piecing and reducing efficiency.
The cooling fan of the frequency converter is prone to clogging with cotton lint, causing overheating faults and affecting production continuity.
Traditional systems have poor adaptability to high-value-added varieties (ultra-low count, ultra-short slub), limiting product upgrades.
The TS633 intelligent controller is adopted, controlling the servo system via the EtherCAT high-speed bus to achieve precise formation control. The spindle inverter shares a DC bus with the servo system, and a built-in power-off synchronization algorithm ensures stable operation during grid fluctuations. The GD350 through-wall frequency converter utilizes natural heat dissipation, completely solving the issue of cotton lint clogging.
