Which details reveal the assembly quality of a packaging machine?
• Verify heat-seal jaw parallelism ≤0.05mm; check four-corner gap with feeler gauge for uniform sealing pressure.
• Check servo motor-reducer coaxiality; coupling radial deviation ≤0.02mm to avoid noise and vibration.
• Manually rotate to inspect chain/synchronous belt tension; chain sag ≤2% of center distance to prevent skipping or overheating.
• Confirm PLC/HMI terminal torque; retighten with screwdriver, ensure wire ferrules match drawings.
• Test safety door interlock: servo enable must cut off within 0.5s when door opens, meeting CE requirements.
