El funcionamiento de pantallas táctiles con PLC facilita y eficiente la configuración de ancho, el ajuste de velocidad y el control de producción.
A slitting machine is designed to convert a large master roll of material into multiple narrower, uniform-width finished rolls through a continuous, controlled process.
1. Unwinding Section
The jumbo roll is mounted on an unwinder, which feeds the material at a constant speed. A tension control system (such as magnetic powder brake or servo control) maintains stable web tension to prevent slack, stretching, or wrinkling during feeding.
2. Guiding & Tension Control
As the material travels through the machine, an EPC (Edge Position Controller) and guide rollers keep the web centered. A closed-loop tension control system regulates tension across unwinding, slitting, and rewinding sections to ensure consistent material flatness and stability.
3. Slitting Unit
The material enters the slitting station, where it is cut into multiple strips of specified width using:
Rotary Shear Slitting: Two circular knives shear the material (ideal for paper, film, and foil, producing clean, burr-free edges).
Razor Slitting: A sharp fixed blade slices thin materials (such as films or non-wovens) at high speed.
Knives are precisely spaced according to required finished widths for multi-strip slitting in one pass.
4. Rewinding Section
The slit strips are rewound onto independent shafts (usually air-expanding shafts). Each strip is controlled by its own tension system to ensure uniform winding density and neatly aligned edges, producing consistent, ready-to-use finished rolls.
Esta máquina de corte adopta una estructura de cuerpo robusta y compacta con alta rigidez, equipada con un conjunto de cortadores de corte de precisión y un mecanismo de ajuste preciso para lograr alta precisión en el corte y un filo de corte liso sin rebabas ni polvo. El sistema de control de tensión en lazo cerrado automático integrado y el dispositivo de corrección de bordes EPC mantienen una tensión constante durante todo el proceso de desenrollado, alimentación, corte y rebobinado, asegurando un funcionamiento estable del material sin desviaciones, arrugas ni deformaciones. Es ampliamente adecuado para papel, película plástica, papel de aluminio, etiquetas adhesivas, tejidos no tejidos y diversos materiales de embalaje flexible. Adoptando PLC y interfaz hombre-máquina con pantalla táctil, la máquina ofrece una configuración de parámetros sencilla, un funcionamiento estable y de bajo ruido, un amplio rango de ajuste de velocidad y alta eficiencia de producción, con alta automatización y fácil funcionamiento. Equipado con protección de seguridad completa y dispositivo de parada de emergencia, adopta piezas principales de alta calidad con baja tasa de fallo y larga vida útil. El diseño modular facilita el mantenimiento diario y la sustitución de piezas, ofreciendo un alto coste para satisfacer la producción en masa a pequeña y gran escala de corte y rebobinado de materiales en rollo.
