Automatic paper cutting slitter machine

Automatic Paper Cutting Slitter Machine for High-Performance Packaging Production

This advanced automatic paper cutting slitter machine is engineered for precision, efficiency, and reliability in industrial packaging applications. Designed to handle a wide range of paper and cardboard materials, it delivers consistent performance across high-volume production environments. With a working width of 1400mm and a maximum design speed of 100 meters per minute—operating at an optimized 80m/min during actual use—it ensures both productivity and accuracy. Ideal for converting large rolls into uniform sheets or strips, this machine supports flexible cutting lengths from 350mm up to 9999mm, making it suitable for custom-sized packaging solutions such as cartons, labels, and die-cut components.

The machine features a robust mechanical structure with hardened knife shafts and precision-engineered rollers that undergo grinding and hard chrome plating (except for the upper and lower blade shafts), ensuring long-term durability and resistance to wear. The main drive motor, rated at 12.5kW, provides stable power transmission, while the variable-frequency controlled feeding motors (3kW each) allow for smooth acceleration and deceleration, minimizing material waste and improving alignment. Its cutting accuracy of ±1mm under uniform velocity conditions makes it ideal for industries demanding tight tolerances, such as corrugated box manufacturing, label printing, and packaging automation systems.

Key features include a sun wheel diameter of φ70mm, which contributes to balanced torque distribution, and an upper-lower knife shaft center distance of φ188mm, enabling precise blade alignment for clean, consistent cuts without chatter or vibration. This equipment is particularly well-suited for integration into automated production lines where continuous operation, minimal downtime, and operator safety are critical. The inclusion of frequency-controlled speed adjustment allows operators to adapt to different paper types and thicknesses—from lightweight kraft paper to heavy-duty board—without compromising quality or throughput.

Commonly used in global packaging facilities, this automatic slitting and cutting system excels in applications involving corrugated cardboard, laminated paperboard, and specialty papers. It serves manufacturers producing shipping boxes, retail packaging, food containers, and industrial cartons who require efficient, repeatable results. Whether part of a standalone setup or integrated into a larger automated line—including rotary die cutters, folder-gluer machines, or flexographic printers—this unit enhances overall workflow efficiency and reduces manual labor costs.

Users report improved consistency in product dimensions, reduced material waste due to accurate length settings, and smoother operation compared to older models. Many appreciate the ease of maintenance thanks to the durable construction and accessible component layout. Operators often note how the intuitive control interface simplifies adjustments for various job requirements, contributing to faster changeovers and higher uptime.
