Efficient Production Speed

The machine speed is infinitely adjustable between 200 and 350 m/min. An S-curve control algorithm is used during acceleration and deceleration to ensure material stability during speed changes. With a speed switching response time of less than 2 seconds, the machine can achieve a continuous daily production capacity of over 50 tons.

Large Coil Diameter Handling Capability

The Roll Slitting Machine supports unwinding diameters up to 1600 mm and rewinding diameters up to 1200 mm. It utilizes a dual-airbag expandable core retention system with a load capacity of 2000 kg. A hydraulic lift platform is provided for coil loading and unloading, reducing roll change time to less than 15 minutes.

Intelligent Control System

Utilizing an industrial-grade PLC and a 10-inch touchscreen, it stores 100 process recipes and supports automatic tool change, tension taper adjustment, and other functions. The system monitors over 20 parameters, including current and temperature, in real time, achieving over 98% fault self-diagnosis accuracy. The control system features remote monitoring, enabling real-time monitoring of equipment operating status and data collection via a network connection.

Highly Customizable

Supporting OEM/ODM partnerships, the machine can be customized for specific configurations, including the number of tools and unwinding methods. Customization options include, but are not limited to, tooling with special materials, explosion-proof electrical systems, cleanroom versions, and specialized roll diameters.

Non-woven Fabric Processing

The Roll Slitting Machine specializes in slitting non-woven materials such as spunlace, hot air, and meltblown. It boasts a slitting speed of 250 m/min and a slitting width tolerance of less than 0.3 mm, making it suitable for the production of medical and protective equipment, with a daily processing capacity of up to 8 tons. The slitting of non-woven rolls maintains neat, burr-free edges, fully meeting the quality requirements of medical-grade products.

Plastic Film Slitting

The Roll Slitting Machine can slitting and rewind plastic films such as PE and PP. Equipped with an anti-static device, it boasts a slitting speed of 300 m/min and a tension control accuracy of ±2 Newtons, meeting the slitting quality requirements of the food packaging film industry. A special flattening device is used during the slitting process to ensure wrinkle-free film.

Specialty Paper Processing

The machine processes specialty papers such as puffed and laminated paper, with a slitting speed of 200 m/min and a dust-free cutting system to minimize paper scraps. It is suitable for the production of high-end packaging materials. The machine is equipped with a humidity control system to maintain a constant humidity level during processing, preventing paper deformation due to humidity fluctuations. The slitting cutters are specially coated to reduce friction with paper and extend cutter life.

Composite Material Slitting

For materials such as aluminum-plastic composites and paper-plastic composites, the Roll Slitting Machine boasts a slitting speed of 220 m/min and is equipped with a delamination detection system to prevent delamination during the slitting process. The machine utilizes a unique tool geometry to ensure simultaneous slitting of all layers without burring. A cooling system is implemented during the slitting process to prevent the composite material from sticking to the cutter due to tool heat.

New Energy Material Processing

Designed for slitting new materials such as lithium battery separators, the machine operates in a clean environment, with a slitting speed of 180 m/min and an online defect detection system, meeting the high material standards of the new energy industry. The machine utilizes an oil-free transmission design to prevent oil contamination of the material.

Tool System Maintenance

Check tool wear every 150 hours of production. Any edge wear exceeding 0.2 mm requires grinding or replacement. Clean and lubricate the tool carriage guide rails weekly to ensure smooth tool movement. Store tools in dedicated tool holders to prevent edge damage. Regularly check the tightening torque of tool mounting bolts to ensure the specified torque value is met.

Transmission System Maintenance

Check the gearbox oil level and quality monthly, and replace the lubricant every 2000 hours of operation. Check the drive belt tension weekly and adjust immediately if the deviation exceeds 15% of the standard value. Regrease the bearings every three months, using designated high-temperature grease. It is recommended to check the coupling alignment monthly, with a deviation of no more than 0.05 mm. Monitor the temperature rise of the reducer during operation. If any abnormal temperature rise occurs, investigate the cause immediately.

Pneumatic System Maintenance

Check the air line seal daily and perform a stroke test on the cylinder monthly. Replace the filter element quarterly to ensure the air supply pressure remains stable within the range of 0.6-0.8 MPa. Check for air leaks when pneumatic components are in operation. If leaks are detected, replace the seals immediately.

Electrical System Inspection

Clean the servo motor encoder monthly and check the PLC module's operating status quarterly. Tighten the electrical wiring thoroughly every six months, ensuring the insulation resistance is no less than 5 megohms. Clean and dust the electrical cabinet monthly and check the cooling fan's operating condition. Check contactor contacts for erosion quarterly and replace any severely eroded parts promptly.

Structural Component Maintenance

Check the tightness of the frame connecting bolts weekly and regrease the guide rails and sliders monthly. Dynamically balance the web support rollers quarterly, ensuring the imbalance is within 0.5 grams. Clean the frame surface monthly and inspect for rust.
