The Maintenance Of The Bearing On The Rubber Bending Roller Is In The High-speed Operation Of The Machine

Use and maintenance of rubber bending roller

Treatment of crystallization on the surface of the rubber roller The surface crystallization closes the capillary holes on the surface of the rubber roller, which will cause the rubber roller to lose its ink-absorbing effect, resulting in uniform ink transfer cloth and easy emulsification of the ink.

The solution is: remove the rubber roller from the machine, lay it flat with a shelf, take the cloth to stick kerosene and pumice powder, and wipe the surface of the rubber roller evenly, and wipe off the crystal layer on the surface of the rubber roller, showing the original The rubber color of the rubber roller, then use car wash water or gasoline to clean the kerosene and pumice powder remaining on the rubber roller, reinstall and adjust the pressure of the rubber roller.

The maintenance of the bearings on the rubber bending rollers. During the high-speed operation of the machine, the wear of the bearings on the rubber rollers is very obvious. Especially when the operator pays attention to the maintenance cloth of the bearings, the wear is even more severe. After the bearing of the rubber roller is damaged to a certain extent, it will produce the jumping friction and squeeze of the rubber roller, which shortens the service life of the rubber roller. And will make the printed products have "ink, water bar" phenomenon. Therefore, the operator is required to take down the rubber roller every week, grease the bearing, and replace those bearings with bad wear and poor rotation to ensure the normal use of the rubber roller.

The influence of workshop environment on rubber rollers In the production of hot and humid weather and dusty surroundings, the high-speed operation of the machine causes the surface temperature of the rubber roller to rise continuously, the rubber roller is heating and expanding, increasing the rubber roller's Friction will shorten the service life of the rubber roller.

The pressure between the rubber rollers is too heavy. The pressure between the rubber rollers is heavy, which will increase the friction between the rubber rollers, make the rubber rollers warm up and heat, increase the squeeze expansion between the rubber rollers, and accelerate the aging and deformation of the rubber rollers. Speed up the emulsification process of ink and water, which is not conducive to the transfer of ink.

The solution is: the pressure between the rubber rollers should be basically the same as the pressure on the contact plate. The experience is to use a piece of 1500 silk, 3cm wide plugs inserted between the test rubber roller, can feel a certain amount of tightness.

After scrubbing, wipe it again with a clean cloth and install the rubber roller on the machine for the next use.
