Name: Continuous Roll-to-Roll Coating Machine XN-LVC-200

Equipment Type: Compact Continuous Roll-to-Roll Doctor-Blade Coating Machine with Infrared Drying Oven and Auto Rewind for Battery Electrode & Thin-Film Research

Product Code: XN-LVC-200

Product Introduction:

The Continuous Roll-to-Roll Coating Machine XN-LVC-200 is a compact continuous roll-to-roll coating machine designed for continuous coating sample preparation and small-batch production experiments. The machine is purpose-built for the continuous coating process of lithium-ion battery cathode and anode sheets, making it well-suited for use in universities, research institutions, and enterprises conducting small-scale experimental production. In addition to lithium-ion battery electrodes, the XN-LVC-200 also supports research on ceramic films, crystalline films, and specialty nano-films. The full housing is constructed from stainless steel for an attractive, durable, and easy-to-operate platform.

Standard Configuration:

The XN-LVC-200 ships with a standard 100 mm wide film former (coating width customizable to customer requirements within the supported 50–220 mm range).

Main Features:

• High-precision modular coating station design — assembled from precision-modular components for repeatable performance
• Independent high-precision PID temperature control for the heating cover, with digital temperature display
• Infrared heating tubes — uniform drying of coated material across the substrate width
• Coating thickness controlled by precise micro-adjustment of the upper doctor-blade gap — 0–3 mm range
• Coating width adjustable via two side baffles inside the slot — customizable within the 50–220 mm range
• Automatic rewind — enables continuous roll-to-roll operation
• Full stainless steel housing — durable, easy to clean, corrosion-resistant
• Compact footprint — L1200 × W600 × H580 mm, 70 kg

Main Specifications:

Values measured by Xnergy. Typical values for reference; not guaranteed unless otherwise specified.

Application Areas:

• Lithium-ion battery cathode sheet continuous coating — small-scale roll-to-roll cathode preparation for NCM, LFP, LCO, and similar chemistries
• Lithium-ion battery anode sheet continuous coating — graphite, Si-C, and other anode material continuous coating
• Small-batch electrode sample preparation for university and corporate research labs
• Ceramic thin-film research — continuous roll-to-roll coating of ceramic films
• Crystalline thin-film research — continuous coating of crystalline thin films
• Specialty nano-film research — continuous deposition for nano-film studies
• Pilot-scale roll-to-roll coating process development for transition from benchtop to production scale

Recommended Operating Procedure:

1. Place the XN-LVC-200 on a stable laboratory floor or workstation with adequate working space and good lighting; connect the power supply per local electrical standards (2 kW). 2. Power on the unit and verify that the modular coating station, doctor-blade adjustment, slot baffles, infrared heating system, PID temperature controller, auto-rewind drive, and motor are all operating normally. 3. Mount the substrate roll (current collector foil) on the unwind side and thread the substrate through the coating station, infrared drying oven (550 mm oven length), and onto the rewind shaft. 4. Adjust the slot baffles to set the target coating width (within 50–220 mm range, standard 100 mm). 5. Set the target blade gap (within 0–3 mm) using the upper doctor-blade fine-adjustment to control wet film thickness. 6. Set the target drying temperature on the digital PID temperature controller (up to 150 °C). Allow the infrared heating system to reach the setpoint and stabilize. 7. Set the mechanical operating speed (up to 500 mm/min). 8. Load the coating slurry, then initiate the run; the substrate advances continuously through the coating station, infrared drying oven, and onto the rewind. 9. Monitor coating quality and adjust parameters as needed during the run. 10. After the run, allow the heating system to cool, then remove the rewound roll. Clean all wetted surfaces with appropriate solvent (water or NMP, depending on the slurry system used) and dry thoroughly before the next run.

Maintenance:

• Frequently wipe the machine with a soft cloth dampened with alcohol to keep it clean
• Lubricate moving parts with oil to keep movement smooth
• If the machine will not be used for an extended period, wipe down the surface of moving components and apply a protective rust-prevention oil
• Periodically inspect screws, nuts, pins, and other fasteners across all parts of the machine to prevent loosening, avoiding equipment-quality issues and personal-safety incidents
• Periodically inspect the infrared heating tubes for damage or contamination; replace if cracked or non-functional
• Periodically inspect the doctor blade and slot baffles for wear or contamination that could affect coating thickness or width

Packaging & Storage:

The XN-LVC-200 ships fully assembled with the modular coating station, upper doctor-blade adjustment mechanism, slot baffles for coating width adjustment, infrared drying oven (550 mm oven length, 150 °C maximum), independent PID temperature controller with digital display, auto-rewind system, motor drive, and stainless steel housing (L1200 × W600 × H580 mm, 70 kg). Store on a stable laboratory floor or workstation in a clean, dry environment, away from heat sources, direct sunlight, and corrosive atmospheres. Disconnect the power supply when the equipment is not in active use. After each use, allow the heating system to cool to room temperature, then clean all wetted-surface components (doctor blade, slot baffles, coating station, oven interior), dry thoroughly, and store in a clean, dry environment. Inspect the infrared heating tubes, PID controller, motor drive, doctor-blade adjustment, and auto-rewind system periodically for wear or signs of degradation.

Safety:

For research and industrial laboratory use only. During operation, do not insert hands or any other body parts into the moving coating station, infrared drying oven, auto-rewind shaft, or any other moving or hazardous working areas to prevent personal injury. Operation by two or more persons simultaneously is not allowed to avoid accidental injury. External (third-party) technical personnel and unauthorized persons must not disassemble the equipment under any circumstances. Do not touch the infrared heating tubes, oven housing, or coated substrate during operation — surface temperatures up to 150 °C can cause severe burns. Always wear appropriate PPE (safety glasses, chemical-resistant gloves, lab coat) when handling slurries, solvents, and coated electrodes. When working with NMP-based slurries or other regulated solvents, operate in a well-ventilated fume hood and follow local regulations on solvent use and recovery — NMP and similar aprotic solvents have specific exposure limits under OSHA, EU REACH, and other regional safety frameworks. Disconnect the power supply before any cleaning, maintenance, or component replacement. Allow the heating system to cool to room temperature before any cleaning or sample-handling operations. Refer to the included user manual for complete safety and operating instructions.

Note: Specifications listed above are typical and for reference only. Actual performance depends on the specific slurry chemistry, coating thickness, drying temperature setpoint, substrate type, and ambient operating conditions — consult published literature and our technical team for guidance on specific roll-to-roll coating-and-drying protocols.
