A slitting machine is a mechanical device that cuts wide sheets of paper or film into multiple narrow strips, commonly used in printing and packaging machinery. Previously, the magnetic powder clutches in slitting machines could not operate at high speeds because high-speed friction of the magnetic powder during operation easily caused high temperatures, shortening their lifespan and, in severe cases, jamming, hindering machine operation and leading to serious consequences for production. This significantly impacted production efficiency.
The traditional control scheme for slitting machines uses a large motor to drive the take-up and unwinding shafts. A magnetic powder clutch is added to the take-up and unwinding shafts. The resistance generated by the magnetic powder clutch is controlled by adjusting the current, thereby controlling the surface tension of the material. The magnetic powder clutch and brake are special automated actuators that transmit torque through magnetic powder filled in the working gap. Changing the magnetic current alters the magnetic state of the powder, thus regulating the transmitted torque. It can be used for stepless speed regulation from zero to synchronous speed, suitable for high-speed fine-tuning and low-to-medium power speed regulation systems. It is also used in unwinding or rewinding tension systems where torque is adjusted by regulating the current to ensure constant tension during winding.
The main feature of the slitting machine is that the magnetic powder clutch acts as a resistance device. Through system control, a DC voltage is output to control the resistance generated by the magnetic powder clutch. Its main advantage is that it is a passive device, allowing for control of relatively small tensions.
Fully automatic slitting machine, Meeting the Needs of Batch Processing for Paper and Film
The fully Automatic slitting machine is a core piece of equipment in the paper and film processing industry. Equipped with an intelligent control system and high-precision mechanical structure, it enables accurate slitting, rewinding, and winding of large rolls, efficiently meeting the batch processing requirements of paper and film. It is suitable for large-scale production in industries such as industrial packaging, printing, and electronics.
The machine is driven by servo motors and features automatic edge guiding, tension control, and length measurement systems. Slitting accuracy can reach ±0.1mm, allowing wide mother rolls to be precisely cut into narrower finished rolls. For paper processing, it can handle kraft paper, coated paper, corrugated board, and more, preventing wrinkles or rough edges and ensuring smooth, flat finished products. For film processing, it is compatible with PE, PP, aluminized films, and Aluminum-plastic composite films. Adjustable tension parameters prevent film stretching or deformation, ensuring suitability for subsequent bag-making, printing, and other production processes.
Additionally, the fully automatic slitting machine offers high-speed continuous operation, with processing speeds of 200–300 meters per minute. With automatic feeding and unloading systems, it significantly reduces manual intervention and improves batch processing efficiency. The machine supports customizable slitting widths and roll diameters, allowing flexible switching between multiple specifications to accommodate both small-batch, multi-lot production and large-scale standardized orders. Its stable performance and precise processing provide reliable support for paper and film processing enterprises, helping reduce costs and improve operational efficiency.
