Common Doctor Blade Fault Solutions for Quick Production Recovery

Various failures often occur with doctor blades in paper mill production. Mastering solutions allows quick troubleshooting to avoid long downtime.
Severe scratches are mostly caused by chipped blade edges or excessive pressure; simply replace the blade in time and reduce the pressure.
Incomplete cleaning results from improper angle or poor contact; readjust the angle to ensure full contact between the blade edge and roll surface.
Blade vibration and abnormal noise are usually due to loose holders or uneven pressure; tighten the holder and balance the pressure accordingly.
For jamming caused by sticky buildup, use spray cleaning, remove impurities promptly, and adjust the blade gap.
Rapid fault diagnosis effectively shortens downtime and ensures continuous production line operation.
