This Unwinding Machine is specifically designed for hygiene product cores, operating at speeds of 230-260 meters per minute. Its patented design is ingenious, truly achieving integrated and highly efficient production processes. Equipped with a dual-station automatic unwinding system and a full servo system for precise control, it not only ensures neat and uniform stacking but also greatly improves production efficiency.

1. High-Speed and Stable Unwinding: This unwinding machine operates at speeds of 180 to 250 meters per minute, with a maximum design speed of 300 meters per minute, meeting the continuous feeding requirements of high-speed production lines. The equipment utilizes a high-precision servo motor and synchronous transmission structure, controlling material deviation within ±1 mm at high speeds, reducing material misalignment caused by speed fluctuations.

2. Precise Tension Management: The equipment employs a closed-loop tension monitoring system to detect and automatically adjust material tension in real time, maintaining constant tension throughout the unwinding process. Test data shows that the system can complete tension compensation within 0.1 seconds, ensuring consistent tightness across different roll diameters. Compared to traditional tension control methods, this system reduces material waste by approximately 20%, improving overall production efficiency.

3. Dual-Station Non-Stop Roll Changing: As a dual-station unwinder, the equipment features a dual-station structure, automatically switching to another roll when material on one roll is exhausted, eliminating the need for line stoppage. Automatic roll changing time is less than 5 seconds, and the disconnection error is less than 2 mm, ensuring a smooth and continuous switching process. The dual-station structure reduces downtime for the entire production line by more than 90%, contributing to stable and continuous production over extended periods.

4. High Material Compatibility: The equipment is compatible with various flexible materials such as SAP sheet, hot air nonwoven, and spunbonded nonwoven, covering material widths from 50 to 130 mm, with a maximum unwinding diameter of 1200 mm. This compatibility has been tested on various materials, including those of different thicknesses and surface friction coefficients, with material feeding deviations consistently controlled within ideal ranges.

5. Precise Automated Control: The equipment is equipped with an intelligent control system that centrally controls multiple parameters such as speed, tension, roll changing, and web correction. The operating interface uses a high-resolution touchscreen that displays real-time operating data, including roll diameter estimation errors of less than 1%, ensuring operators can accurately monitor remaining material. The control system adopts an industrial PLC and multi-axis drive collaborative computing structure, which can still ensure a response speed of less than 20 milliseconds under complex working conditions, enabling high-speed continuous production.

1. Hygiene Product Production Line: Unwinding machines are widely used in production lines for hygiene products such as diapers, sanitary napkins, and nursing pads. These lines typically operate at speeds exceeding 200 meters per minute, requiring extremely high continuity of material supply. The equipment ensures a stable supply of SAP sheets and nonwoven materials at high speeds, preventing batch defects due to material shortages.

2. Nonwoven Fabric Lamination and Processing Line: In the nonwoven fabric lamination process, the flatness of the material directly affects the bonding quality. Unwinding machines provide a stable material path and continuous feeding capability, ensuring that nonwoven materials of different weights and processes maintain ideal flatness. For processes such as printing, embossing, and lamination, stable feeding reduces process deviations and improves controllability.

3. Film Material Production and Conversion: Film materials such as PE film and composite films are sensitive to tension. Uneven feeding can easily cause wrinkles and tensile deformation. Unwinding machines maintain low-deviation tension during film material unfolding, preventing damage from uneven stress. Its automatic deviation correction function reduces film material deviation, improving the flatness of finished products in downstream processes such as slitting, printing, or heat sealing.

4. Paper and Composite Paper Industry: The equipment can handle various paper materials of different widths and thicknesses, including absorbent paper, filter paper, composite paper, and functional paper. Paper materials are easily affected by changes in humidity and tension during unfolding, while the constant tension output of the dual station unwinder maintains the stability of the paper structure, reducing paper breaks.

5. Medical Material Supply System: The medical industry commonly uses materials such as sterile packaging paper, medical non-woven fabrics, and medical dialysis membranes. These materials require high precision and have high waste costs. The precise material feeding control of the dual station unwinder can avoid material tearing and creases, improving the sealing integrity of medical packaging.

1. What materials is the Unwinding Machine suitable for?

It is suitable for various roll materials, including SAP sheets, hot-air nonwoven fabrics, spunbond nonwoven fabrics, films, and paper materials, meeting the feeding requirements of different production lines.

2. Can the dual-station unwinder truly achieve roll changing without stopping the machine?

Yes. The dual-station structure can automatically receive materials before the old roll is exhausted, with minimal receiving error, ensuring continuous operation of the production line.

3. What is the maximum operating speed of the equipment?

The normal operating speed is 180 to 250 meters per minute, with a maximum design speed of 300 meters per minute, adjustable according to materials and processes.

4. Does the equipment require frequent maintenance?

Routine maintenance mainly involves cleaning, checking guide rollers, and maintaining bearing lubrication. The machine has a simple structural design, a relatively long maintenance cycle, and short downtime.

5. Is the material specification change complicated?

When changing the material width and roll diameter, simply set the relevant parameters on the control interface, and the automatic correction and tension system can automatically adapt to the new material.
