A kraft paper slitting machine is specifically designed to slit and rewind large-format parent rolls produced by paper mills, according to downstream requirements. Its core function is to accurately slit wide parent rolls into smaller rolls of predetermined width and length, and then rewind them into finished rolls with uniform specifications and neat winding. It can be integrated with equipment such as spiral paper tube machines and tube cutting machines to form a paper tube production line for manufacturing toilet paper cores.

Working Principle of a Kraft Paper Slitter and Rewinder
The core of a kraft paper slitting and rewinding machine can be divided into two main systems: paper unwinding tension control and slitting and rewinding.
1. Paper Unwinding and Tension Control: The kraft paper roll removed from the paper machine is placed on the unwinding rack. A braking device maintains the tension of the paper web, and brakes quickly when the paper breaks to reduce paper loss.
2. Slitting and Rewinding: The paper web is cut to the required width by the guide rollers and slitting mechanism, and then rewound into a roll according to the set tightness and diameter.
Kraft Paper Slitting and Rewinding Machine Composition
The kraft paper slitting and rewinding machine mainly consists of the following five core components, working together to complete the processing from raw paper to finished rolls:
Paper Unwinder:Holds the raw paper rolls to be processed, providing a stable supply of paper webs for subsequent processes.
Tension Control Device: Adjusts and maintains paper web tension in real time, ensuring the smoothness of the slitting and rewinding process.
Paper Guide Roller and Slitting Mechanism:The paper webs are conveyed by the paper guide rollers and precisely slit to a set width by the slitting mechanism.
Rewinding Mechanism: Rewinds the slit paper strips into independent, neat finished paper rolls.
Transmission System:Provides power to all parts of the equipment, ensuring coordinated and efficient operation of the entire machine.
Features of the Paper Slitting and Rewinding Machine
1. The main unit uses thick steel plates cut and welded by CNC, ensuring machine stability and resistance to deformation.
2. The main motor uses a vector high-torque frequency converter for speed regulation.
3. The bobbin is securely and smoothly wound on both sides, resulting in low noise and stable operation.
4. After cutting, the adhesive tape on both sides is smooth and burr-free, making operation very convenient.
5. Parameters such as slitting width and paper roll diameter can be adjusted according to different needs, offering high flexibility.
