Printing ink buffering device

The utility model relates to a printing ink buffering device which can comprise an inner ring buffering baffle and an outer ring buffering baffle, the outer ring buffering baffle is provided with an axial opening, the inner ring buffering baffle is provided with an axial arc-shaped groove facing the axial opening, the axial opening and the axial groove form a printing ink inlet, and the printing ink inlet is communicated with the inner ring buffering baffle. The inner ring buffering baffle is provided with a honeycomb grid part, and the honeycomb grid part is opposite to the axial arc-shaped groove in the radial direction, so that printing ink flows towards the two sides from the printing ink inlet and enters the inner ring buffering baffle through the honeycomb grid part. According to the utility model, the new ink and the old ink can be fully fused without influencing the ink absorption efficiency of the ink pump, thereby greatly reducing the waste product of printing product color difference caused by the
