A lubricating assembly for a printing press inking roller

Abstract

The application relates to the technical field of ink roller lubricating components, in particular to a lubricating assembly for a printing machine ink roller which comprises connecting plates, two groups of the connecting plates are fixed at the two ends of a roller core, an ink roller sleeve is arranged outside the roller core, one side of the connecting plate is provided with a surrounding frame, the surface of the surrounding frame is provided with a connecting handle, the inner ring surface of the surrounding frame is provided with a rotating shaft, the outer side of the rotating shaft is provided with a surrounding ring, and the surrounding ring is fixed on the surface of the connecting plate. The beneficial effect is that after the clamping ring is buckled outside the surrounding frame, the rubber ball cavity of the inner ring surface of the oil collecting ring is inserted into the corresponding perforation, after the ink roller is installed, in the rotating process, the lubricating oil in the oil collecting ring is dripped into the perforation through the rubber ball cavity to soak the cotton core, the lubricating oil on the surface of the cotton core is soaked between the surrounding frame and the surrounding ring, and the lubricating oil is soaked between the surrounding ring and the rotating shaft, so that the continuous lubricating effect of the connecting plate in rotation is realized.
