Consistent Traction with Five-Roller Haul-Off System & Tension Feedback
Product Introduction
The stability of the haul-off process is essential for maintaining coordinated operation of the entire production line and ensuring product quality. This system employs a five-roller haul-off machine that provides superior gripping power and operational smoothness through progressive engagement and traction of five large-diameter chrome-plated rollers. An integrated high-precision tension sensor monitors haul-off tension in real-time and feeds the signal back to the PLC to form a closed-loop control system. This system instantly compensates for minor tension fluctuations, ensuring products exiting the heat-setting stage enter subsequent stages with constant, uniform tension, providing a solid foundation for producing finished rolls with smooth end faces and perfect winding formation.

Customer Questions & Answers
What are the specific advantages of a five-roller haul-off compared to the common three-roller type?
The core advantages lie in larger wrap angle and more uniform pressure distribution. The five-roller structure allows the tape to be held more gently and steadily over a longer curved surface, thoroughly eliminating the risk of local slippage. This is particularly crucial for high-speed operation, smooth-surfaced, or thicker PP tape, ensuring absolutely stable line speed and fundamentally preventing uneven thickness or intermittent shake caused by traction slippage.
How does the tension feedback closed-loop work automatically?
The system forms an intelligent regulation loop: Detection (sensor collects real-time tension signal) → Comparison (PLC compares measured value with set value) → Decision & Execution (PLC calculates deviation and immediately outputs commands to fine-tune the torque or speed of the five-roller traction motor) → Re-detection. This continuous process achieves dynamic tension constancy.
Can this system solve winding irregularities (e.g., chimb, collapse)?
It is one of the key prerequisites for solving this problem. Winding irregularities often stem from periodic or random tension fluctuations in the tape entering the winding machine. The "ultra-stable tension source" provided by the five-roller haul-off and tension feedback closed-loop system acts like delivering "calm water flow" to the winding process, making subsequent winding tension control easier, thereby significantly improving roll formation and yielding ideal finished rolls with smooth end faces and consistent tightness.
