Zusammenfassung:	The utility model discloses a novel smearing type ink coating device comprising an ink pressing roller and an ink coating roller, wherein the outer surface of the ink pressing roller is provided with a groove, ink ribbons are compressed between the groove of the ink pressing roller and the ink coating roller, the depth H of the groove is 0.04-0.08mm, and the spacing a between the ink pressing roller and the ink coating roller is 0.05mm. The structure of the novel smearing type ink coating device is designed through long-term test summarization by technicians, the groove of a certain depth is additionally arranged on the ink pressing roller to enable a gap to be always reserved between the groove of the ink pressing roller and the outer surface of the ink coating roller when the ink pressing roller and the ink coating roller are compressed, glass-shaped crystals on the edges of the ink ribbons in the groove are prevented from being crushed, the production quality of the ink ribbons during ink coating is ensure
