When the viscosity of the ink is relatively high, it accumulates under the first lower hopper 12. The motor 4 is started to drive the transverse stirring shaft 51 to rotate. Through the transmission box 5, when one transverse stirring shaft 51 rotates, the other three transverse stirring shafts 51 are also driven to rotate, so as to break up and stir the ink above, thereby increasing the fluidity of the ink; through the transmission box 5, the transverse stirring shaft 51 drives the longitudinal stirring rod 6 to rotate when rotating, and the rotation of the longitudinal stirring rod 6 stirs the bottom of the ink, further increasing the fluidity of the ink. The output power of the motor 4 can be changed according to the different viscosities of the ink, so that the filling speed of different inks can be kept consistent.
