Automatic Winding with 4 Independent Servo-Controlled Spindles
Winding is the final process in the production line, directly impacting the appearance quality of finished rolls and their subsequent usability. This machine features a four-spindle independent automatic winding system where each spindle is driven by a dedicated 1.2KW servo reduction motor, enabling precise individual control of speed and tension. Combined with PLC intelligent control, it achieves automatic roll change at preset length, pre-alarm stop, and constant tension functions. The result is neat winding formation without loose or overlapping layers, significantly improving finished product yield and customer satisfaction.

Customer Questions & Answers
What is the biggest advantage of "independent servo control" for winding?
The primary advantage is achieving true "per-spindle tension control". Even with minor variations in thickness or elasticity across the four straps, each servo motor performs fast, independent torque compensation based on its specific tension setting. This ensures each strap is wound at optimal tightness, completely eliminating uneven tension issues caused by shared power sources.
How is "automatic stop at preset length" achieved? What is the accuracy?
This function is accomplished through an electronic length counter at the front that measures strap length and sends real-time signals to the PLC. Operators preset the desired roll length (in meters) via the touch screen interface. When the target value is reached, the PLC controls the corresponding winding spindle to automatically decelerate and stop precisely while activating audible/visual alarms for roll change notification. Accuracy depends on the length counter system, achieving ±0.1%.
How is the neatness of winding (no overlapping edges) ensured?
Winding neatness is guaranteed by two key mechanisms: 1) Constant Tension Control: The servo system maintains stable winding tension, forming the foundation for uniform rolls; 2) Traversing System: An independent traversing device (guide wheel) driven by a 500W servo motor guides the strap back and forth. Its movement speed precisely matches the winding speed, ensuring the strap is wound evenly and flatly layer by layer on the core.
