[0032] Specifically, the high-density liquid in the mixing bucket 11 is stirred by the mixing shaft 42 , while reducing the impact of the liquid on the inner wall of the mixing bucket 11 during stirring; the mixing shaft 42 and the output shaft 22 rotate independently of each other through the first bearing 23 .

[0034] Specifically, the deflection rod 51 vertically spans the interior of the placement slot 5 , and the cross-sectional diameter of the deflection rod 51 is smaller than the cross-sectional width of the placement slot 5 .
[0035] A first groove 52 is provided on the top and bottom surfaces of the placement groove 5. The cross section of the first groove 52 is symmetrical with the deflection rod 51 along the cross section midline of the placement groove 5. A magnetic block 7 is provided inside the first groove 52. The end surface of the magnetic block 7 is flush with the end surface of the placement groove 5.
[0036] Specifically, the cross-section of the first groove 52 is the same as that of the deflection rod 51 , and both are smaller than the cross-section width of the placement groove 5 ; the end surface of the magnetic block 7 is flush with the end surface of the placement groove 5 , keeping the inner wall of the placement groove 5 flat.
[0037] A deflection blade 6 is arranged inside the placement groove 5 . The shape of the deflection blade 6 corresponds to the shape of the placement groove 5 .

When the stirring shaft 41 rotates, the centrifugal force of the stirring shaft 41 is greater than the magnetic force between the placement slot 5 and the magnetic block 7 of the deflection leaf 6, so that the deflection leaf 6 deflects around the deflection rod 51, and one end of the deflection rod 51 on one side of the placement slot 5 will generate downward pressure on one end of the deflection leaf 6, thereby limiting the deflection angle of the deflection leaf 6, and when the stirring shaft 41 stops rotating, the deflection leaf 6 is reset.
[0041] Hydraulic seats 32 are arranged on both sides of the second motor 31, and the hydraulic seats 32 are perpendicular to the feed port 14.

[0042] Specifically, the top cover 12 is separated from the tank body 1 by the hydraulic rod 33, so as to facilitate the removal of the mixed ink, and the bottom plate 2 is fixed so that the tank body 1 can rotate independently; the tank body 1 is sealed by the rotating groove 13, and the tank body 1 is rotated inside the rotating groove 13, so that the tank body 1 can rotate independently from the top cover 12.
[0043] During use, ink and medium are added into the tank body 1 through the two feed ports 14, and the first motor 21 and the second motor 31 are started to rotate the tank body 1 and the rotating shaft 4 in opposite directions. The tank body 1 mixes ink and medium of different densities when rotating; when the stirring shaft 41 rotates, the deflection blades 6 deflect outward to stir and impact the ink, medium and the mixed liquid, thereby increasing the mixing speed of the ink and medium and completing the mixing of the ink and medium.
