1, Daily cleaning, the corrugated roller for a simple cleaning can increase the life of the corrugated roller. By removing paper dust, carbonized adhesive and other dirt, will reduce wear. Remove the pasting roller, remove the pressure roller and release the load on the corrugating roller. There is a steam hose under the corrugating roller, which pours light engine oil into it, turning slowly on one side and on the other. If the injection of enough oil, please do not roll the corrugating idling, otherwise it will cause damage and wear will soon damage the corrugating. Hot corrugating roller can not be washed with water, or it will break or twist. If the water contains impurities, will be in the water evaporation, residual in the corrugated roll. Gutters should be cleaned. Vacuum corrugating roller should be along the direction of the vacuum chamber and gas hole. Sometimes a vacuum blower blows out debris.
2, Lubrication, do not let the corrugated roller dry rotation. If the order runs out and the paper need to immediately back pressure and stop the machine. If it is a single-sided machine should be maintained before the shutdown of rotation to lubricate the corrugating roller. This is essential to protect the coating surface. Because the corrugating rollers and pressure bearings operate at high temperatures and pressures,Proper lubrication is necessary. The lubrication system should be removed monthly to ensure proper flow of oil to ensure proper lubrication of bearings, otherwise the old bearing will cause vibration and uneven and reduce the life of corrugated roller, wear and reduce the quality of cardboard.
3, Alignment and adjustment, if the corrugated roller can not keep parallel, not only affect the quality of cardboard, but also affect the corrugated roller life. So please check if parallel or cardboard quality is deteriorating as part of routine maintenance. The load of corrugating roller is another crucial factor that affects its life. Only enough pressure is used to obtain the pitch, and excess pressure will reduce the life of the corrugating roller. Sometimes the operator will increase the load to supplement the heat. This is not effective, corrugated roller minimum temperature of 177 degrees, steam pressure of 180 psi, which can not be changed. If you think that the formation of corrugated cardboard has problems, first of all should check the temperature of the corrugated roller. Do not increase the pressure to increase the temperature. Also make sure the operator often uses a pyrometer to check and determine the surface temperature of the corrugating roller.
