As shown in Figures 2 and 3, when wiping off the
Since the head 5 moves away from the top to the bottom over a fixed moving distance, ink scattering caused by the tip of the blade 10 being elastically separated can be effectively prevented. While wiping, the ink could be swept downward as shown by the arrow in Figure 3, and the effect of vertical wiping improved the ink wiping effect.
