High Speed Film Slitting Machine

Jiuyi's industrial high speed film slitting machines are engineered for continuous, precision converting of thermoplastic films, laminates, paper, and metal foils. Built for flexible packaging converters and film manufacturers requiring consistent output at elevated speeds, these machines integrate closed-loop tension control, rigid cast-iron frame construction, and automated knife positioning to eliminate telescoping, web wandering, and downtime. Conforming to CE and OSHA safety standards, the equipment ensures seamless integration into modern, safety-conscious European and North American production environments.

Closed-Loop Tension Regulation: Unwind and rewind tensions are dynamically monitored via load cells and regulated by Siemens servo drives, preventing stretching or deformation of thin substrates (e.g., 12-micron PET, 20-micron BOPP) during acceleration and deceleration.
Vibration-Damped Frame: The chassis utilizes 50 mm thick annealed steel plate, stress-relieved to eliminate structural harmonics and suppress chatter at 800 m/min operation.
Automated Web Guiding (EPC/LPC): An ultrasonic edge sensor paired with a high-response ball-screw actuator maintains lateral web deviation within +/- 0.05 mm prior to the cutting station.
Edge Trim Management: An integrated high-capacity centrifugal waste blower and negative pressure suction system (or optional online continuous trim winders) instantly clears polymer scrap.
Energy-Saving Regenerative Braking: IE4 high-efficiency motors combine with an energy feedback unit, feeding kinetic energy recovered during rapid roll deceleration back into the plant grid.
Precision Rewind Shafts: Differential friction rings mounted on a hardened pneumatic shaft compensate for thickness variations across wide master rolls, ensuring uniform roll density from core to outer diameter.

Foundation & Floor Loading: Requires a leveled concrete floor of minimum 150 mm thickness. Dynamic load distribution drawings are provided prior to delivery.
Power & Utility Supply:
Main electrical feed: 380V +/- 10%, 3-phase, 50/60 Hz (25 kW to 45 kW total connected load).
Compressed air: Clean, dry, oil-free air supply at 0.6 MPa to 0.8 MPa with a minimum flow rate of 300 L/min.
Environmental & Safety Compliance: Operating ambient temperature between 10°C and 40°C; relative humidity under 85% non-condensing. Machine perimeter safety is enforced via Type 4 safety light curtains, emergency pull cords, and interlocked mechanical guarding conforming to CE/OSHA standards.

Flexible Packaging: Slitting multi-layer laminated films (BOPP/PE, PET/AL/PE) for snack food pouches, vacuum bags, and liquid spout packaging.
Industrial & Optical Films: Converting release liners, protective PET films for flat-panel displays, and functional coatings.
Battery Manufacturing: Processing lithium-ion battery separator films (PE/PP microporous membranes) and electrode current collectors.
Paper & Label Stock: Converting thermal paper, adhesive label stock, and siliconized backing papers.

Knife & Tooling Options: Interchangeable setups utilizing high-chrome alloy or tungsten carbide shear circular knives, quick-change razor blades in air grooves, and pneumatic crush-cut scoring knives with tool-less replacement for full changeovers in under 10 minutes.
Unloading Solutions: Integration of hydraulic roll unloading trees, robotic arm roll handlers, or cantilevered unloader carts.
Automation Upgrades: Automated laser core alignment systems projected onto the rewind shaft for rapid, error-free core placement.
Data Integration: OPC UA and Modbus TCP protocols enabled for direct connection to Factory Manufacturing Execution Systems (MES).

Dimensional Verification: All machined frames, walls, and aluminum guide rollers are checked on a coordinate measuring machine (CMM). Guide rollers undergo dynamic balancing to G2.5 grade.
Component Traceability: Drives, PLCs, and low-voltage switchgear are sourced directly from authorized industrial automation channels (Siemens, Schneider, Yaskawa).
Factory Acceptance Testing (FAT): Every machine undergoes a 72-hour continuous dry-run test followed by an actual material test run matching the customer's specified web width, thickness, and target speed before crating. Test reports, vibration spectrum logs, and safety interlock verification certificates are supplied

Corrosion Protection: Unpainted precision steel surfaces are coated with industrial anti-corrosion grease and wrapped in VCI film. The machine enclosure is sealed in a vacuum-heat-sealed barrier foil containing silica gel desiccants.
Crate Specifications: Secured onto heavy-duty fumigated wooden skids using internal tie-down brackets. Outer crating consists of ISPM 15-compliant export-grade plywood boxes (18 mm minimum thickness) lined with waterproof membrane.
Documentation Package: Each shipment includes physical and digital copies of the English Operation Manual, CE compliance declaration, Electrical Schematic Diagrams, Pneumatic Layout, PLC Source Code Access, and Spare Parts Catalog.
