Problem | Reason | Measure |
Uneven wear, frequent blade replacement | 1. The surface of roller or dryer is uneven 2. The doctor holder is damaged or dirty 3. Sediment | 1. Use a softer blade 2. Clean, repair or replace the doctor holder 3. Use abrasive blade |
Excessive wear on middle or edge of blade | 1. The blade is not installed on the top of the roller 2. The old blade sinks (or leaves) the roller or dryer | 1. Refit or add gasket at the back of blade if necessary 2. Replace the old and sunken blade |
Excessive wear at one end of blade | The displacement of blade is not parallel to the axial direction of roller or dryer | Add gasket, if necessary, move bearing and bracket to adjust scraper parallel to axial direction |
The blade is worn evenly, but the end face is rough | 1. There is deposit on the surface of roller or dryer 2. The pressure of blade is too high 3. The material of blade is too hard | 1. Use abrasive blade when necessary 2. Reduce the pressure 3. Use a slightly soft blade |
Excessive wear in sheet area | The sheet leaves sediment on the roller or dryer | 1. Use abrasive blade when necessary 2. Trim the edge of blade frequently 3. Use blade with slotted end to prevent excessive pressure on both ends of roller or dryer |
Excessive wear out of sheet area | The sheet lubricates the roller or dryer | Use blade with slotted end |
Local depression | The blade is damaged, electrostatic (discharge/ electrolysis /heating) | Insulate the blade from the holder or use a non-metallic blade |
The blade produces burr | 1.The material of the blade is too soft 2. The pressure is too high 3. The angle of the blade is too small | 1. Use a slightly hard scraper 2. Reduce the pressure 3. Adjust the bearing or bracket to increase the angle, and use the instrument to check and correct the angle |
