The bearing and the shaft head inside the rubber roller are very precise, and there is a slight difference in the pool, which will directly affect the use effect. This requires correct methods and techniques to be used both in daily use and in maintenance:
1. Excessive pressure between the composite rubber rollers will increase the friction between the rubber rollers, accelerate the aging and deformation of the rubber rollers, and accelerate the emulsification process of the ink and water, which is not conducive to the transfer of ink. The solution is that the pressure between the rubber rollers should be basically the same as the pressure at the contact plate.
2. Treatment of surface crystallization of composite rubber roller. The surface crystallization closes the capillary pores on the surface of the composite rubber roller, which causes the rubber roller to lose the affinity of the ink, which causes the ink to be evenly distributed, and the emulsification of the ink is likely to occur. The solution is to remove the rubber roller on the machine, wipe off the crystallized layer on the surface of the composite rubber roller, reveal the rubber color of the original rubber roller, and then use the car wash water or gasoline to remove the kerosene and pumice remaining on the rubber roller. Clean the powder, reinstall and adjust the pressure of the rubber roller.
3. Maintenance of the bearing on the composite rubber roller. In the high speed operation of the machine, the bearing wear on the rubber roller is obvious. After the bearing of the rubber roller is damaged to a certain extent, the friction friction and extrusion of the rubber roller will occur, and the service life of the rubber roller will be shortened. Therefore, the operator is required to take down the rubber roller every week, butter the bearing, and replace those bearings that are so badly worn and poorly rotated to ensure the normal use of the rubber roller.
4. The impact of the workshop environment rubber roller. In the hot and humid weather and the environment from the surrounding dust, the high-speed operation of the machine makes the surface temperature of the rubber roller rise continuously, and the rubber roller expands and expands, which increases the friction of the composite rubber roller. The life of the roller is shortened. Therefore, in a conditional factory, the offset plug-in requires air conditioning to keep the workshop clean and clean, so that the machine can be produced in a good environment. Only when it is produced in a good workshop environment will it produce high-quality products.
