Operation Specifications for Fully Automatic Roll-to-Roll Screen Printing Machine 

 

 

Fully automatic roll-to-roll screen printers are high-efficiency, precision printing equipment, widely used in producing electric heating films and similar products. This specification is formulated to ensure safe, stable operation, consistent printing quality, and enhanced productivity. 

 

 

 I. Pre-Operation Preparation 

 

**Personnel** 

Operators must complete professional training (familiar with equipment structure, performance, procedures, and safety protocols) and pass assessments before operating. Unauthorized operation is strictly prohibited. 

 

**Environment Check** 

Ensure the workspace is clean, well-ventilated, and free of flammables, explosives, or corrosive gases. Maintain temperature at 15-30℃ and relative humidity at 40%-60% to avoid impacting quality or equipment performance. 

 

**Equipment Inspection** 

- Check components (screen frame, squeegee, feeding/rewinding rollers) for integrity and secure connections; no looseness or damage. 

- Inspect transmission systems (motor, chain, belt) for smooth operation; no jamming or abnormal noise. 

- Verify pneumatic system: air pressure 0.5-0.6MPa (as specified), air pipes tightly connected, no leaks. 

- Check electrical system: voltage stable within AC380V±10%, indicators/buttons/switches functional, wiring intact. 

 

**Material Preparation** 

- Substrates (e.g., PET film) must be flat, clean, and free of oil, dust, or wrinkles. 

- Inks/pastes: confirm compliance with production specs, stir evenly to avoid sedimentation or caking. 

- Screen plates: check for proper tension, clear patterns, no damage/deformation, and unclogged mesh. 

 

 

 II. Startup Procedure 

 

- Turn on main power; wait for self-inspection. Proceed only after indicators show normal status. 

- Open compressed air valve, adjust pressure to specifications; verify pneumatic components function. 

- Start control system, enter interface, and set parameters (printing speed, pressure, squeegee angle, feeding length, rewinding tension, etc.) per requirements. 

- Mount substrates on feeding rack; adjust deviation correction to ensure stable, centered feeding. 

- Install screen plate on frame, align with printing position, and secure firmly. 

- Pour ink/paste into trough; adjust squeegee position/height for proper contact with the screen. 

 

 

 III. Printing Operation 

 

- Conduct test printing via inching or single-cycle mode. Check pattern clarity, registration accuracy, and ink thickness; adjust parameters if abnormal. 

- After qualified tests, start continuous operation. Operators must monitor equipment and print quality, inspect outputs regularly, and stop immediately for troubleshooting if issues arise. 

- Replenish ink/paste timely to avoid shortages; keep trough clean to prevent contamination. 

- Monitor feeding/rewinding for smooth transport, neat rewinding, and stable tension. Stop immediately if substrate deviates or breaks; resume after fixing. 

- Never touch moving parts (rollers, squeegee) during operation. Power off before adjustments or cleaning. 

 

 

 IV. Shutdown Procedure 

 

- Stop continuous operation; turn off control system once equipment halts. 

- Close air valve to release pneumatic pressure. 

- Turn off main power. 

- Clean ink/paste residues; use dedicated solvents to clean screen, squeegee, and trough. 

- Seal and store leftover ink/paste in designated areas. 

- Organize printed products in labeled storage zones. 

- Clean workspace; return tools/gauges to their positions. 

 

 

 V. Routine Maintenance 

 

**Daily** 

- Clean surface dust and oil. 

- Lubricate moving parts; check and replace pneumatic filter cartridges as needed. 

 

**Weekly** 

- Adjust tension of chains/belts; secure screen/squeegee frames. 

- Tighten loose electrical terminals. 

 

**Monthly** 

- Inspect motors/reducers for abnormal temperature/noise; troubleshoot promptly. 

- Clean and lubricate precision components (rails, sliders) to prevent wear. 

- Verify safety devices (emergency stops, limit switches) function properly. 

 

 

 VI. Safety Precautions 

 

- Operators must wear PPE (workwear, cap, safety glasses, etc.). 

- Stop immediately, cut power, and report to supervisors if abnormal noise, vibration, or smoke occurs; restart only after troubleshooting. 

- No unrelated items on equipment to avoid hazards. 

- Maintenance must be performed by professionals; no unauthorized disassembly/modification. 

- Conduct regular safety checks to ensure functional safety devices. 

 

 

Strict adherence to this specification is required to ensure safe operation and stable product quality.
