Working Principle of Non-Woven Fabric Unwinding Machine

1. Overview of the Unwinding Machine:

The non-woven fabric unwinding machine consists of several key components, including a roll stand, tension control system, edge guiding system, and a drive system. Each component works in harmony to ensure the unwinding process is carried out smoothly and accurately.

2. Roll Stand:

The roll stand is responsible for holding the fabric roll securely in place. It is equipped with a pneumatic shaft, which expands to grip the core of the fabric roll firmly. This ensures that the roll rotates smoothly during unwinding, preventing any slippage or misalignment.

3. Tension Control System:

The tension control system is crucial for maintaining the appropriate tension in the unwinding fabric. It consists of a dancer roller, load cells, and a controller. The dancer roller moves up and down based on the tension in the fabric, while the load cells measure the tension and send the data to the controller. The controller adjusts the speed of the unwinding process accordingly, ensuring consistent tension throughout.

4. Edge Guiding System:

To ensure the fabric unwinds evenly, an edge guiding system is employed. It consists of sensors that detect the edges of the fabric and send signals to the unwinding machine's control system. The control system then adjusts the position of the fabric using edge guiding rollers, ensuring the fabric unwinds straight and avoids any lateral misalignment.

5. Drive System:

The drive system provides the necessary power to unwind the fabric roll. It typically consists of an AC motor, gearbox, and drive roller. The AC motor drives the gearbox, which in turn rotates the drive roller. The fabric roll is in contact with the drive roller, and as it rotates, the fabric unwinds smoothly and continuously.

Conclusion:

The non-woven fabric unwinding machine operates on a sophisticated mechanism to ensure efficient and precise unwinding of fabric rolls. The roll stand securely holds the fabric, while the tension control system maintains consistent tension. The edge guiding system ensures the fabric unwinds straight, and the drive system provides the necessary power for smooth unwinding. Understanding the working principle of this machine is essential for optimizing the production process of non-woven fabrics and achieving high-quality results.
