[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] This embodiment of an ink emulsification and dispersion device includes a dispersion motor 1, a dispersion box 2, a primary rotary dispersion mechanism 3, a secondary rotary dispersion mechanism 4, and a tertiary rotary dispersion mechanism 5. The dispersion motor 1 is located at one end of the dispersion box 2. The dispersion box 2 has a dispersion cavity 21. The other end of the dispersion box 2 and one side of the dispersion box 2 are respectively provided with a suction port 22 and a discharge port 23 communicating with the dispersion cavity 21. The primary rotary dispersion mechanism 3, the secondary rotary dispersion mechanism 4, and the tertiary rotary dispersion mechanism 5 are sequentially arranged in the dispersion cavity 21 from the end near the suction port 22. The discharge port 23 is located on one side of the tertiary rotary dispersion mechanism 5. The primary rotary dispersion mechanism 3, the secondary rotary dispersion mechanism 4, and the tertiary rotary dispersion mechanism 5 are all connected to the rotating shaft end of the dispersion motor 1.

[0021] By sequentially setting multiple stages of rotating dispersion mechanisms in the dispersion chamber 21, the ink is subjected to a combination of multiple stages of shearing, friction, centrifugal extrusion, and liquid flow collision after entering the dispersion chamber 21 through the suction port 22. This achieves uniform emulsification and breakup of the ink, ensuring that the viscosity, gloss, fineness, and color of the final discharged ink all meet the requirements.

[0022] Preferably, the primary rotary dispersion mechanism 3 includes a first rotor 31 and a first stator 32. The first rotor 31 is connected to the shaft end of the dispersion motor 1, and the first stator 32 is fixed in the dispersion cavity 21. Under the drive of the dispersion motor 1, the first rotor 31 and the first stator 32 rotate relative to each other. The outer side of the first rotor 31 is provided with a plurality of uniformly distributed first stirring teeth 311, and the outer side of the first stator 32 is provided with a plurality of uniformly distributed first fixing teeth 321. A first shearing gap is formed between the first stirring teeth 311 and the first fixing teeth 321.

[0023] During operation, the drive motor drives the first rotor 31 to rotate, while the first stator 32 is fixed in the dispersion cavity 21, so that the first stirring teeth 311 on the first rotor 31 and the first fixing teeth 321 on the first stator 32 are precisely matched. Through the high-speed and stable rotation of the first rotor 31, a comprehensive kinetic energy efficiency such as high frequency and strong circumferential tangential velocity and angular velocity is formed. Under the action of the first stator 32, a comprehensive effect of strong and reciprocating hydraulic shearing, friction, centrifugal extrusion and liquid flow collision is formed in the first shear gap, so as to achieve the primary emulsification and dispersion of ink.

[0024] Preferably, the secondary rotary dispersion mechanism 4 includes a second rotor 41 and a second stator 42. The second rotor 41 is connected to the shaft end of the dispersion motor 1, and the second stator 42 is fixed in the dispersion cavity 21. Under the drive of the dispersion motor 1, the second rotor 41 and the second stator 42 rotate relative to each other. The outer side of the second rotor 41 is provided with a plurality of evenly distributed second stirring teeth 411, and the outer side of the first stator 32 is provided with a plurality of evenly distributed second fixing teeth 421. The second stirring teeth 411 and the second fixing teeth 421 are provided with two rows, one inside and one outside. A second shearing gap is formed between adjacent second stirring teeth 411 and second fixing teeth 421.

[0025] During operation, the drive motor rotates the second rotor 41, while the second stator 42 is fixed in the dispersion cavity 21. This allows for precise engagement between the second stirring teeth 411 on the second rotor 41 and the second fixing teeth 421 on the second stator 42. The high-speed, stable rotation of the second rotor 41 generates high-frequency, intense circumferential tangential velocity and angular velocity, resulting in a comprehensive kinetic energy efficiency. Under the action of the second stator 42, a strong, reciprocating hydraulic shearing, friction, centrifugal extrusion, and liquid flow collision effect is generated in the second shearing gap, achieving secondary emulsification and dispersion of the ink. Both the second stirring teeth 411 and the second fixing teeth 421 are arranged in double rows, ensuring that the ink undergoes two dispersion shearing processes within the secondary rotary dispersion mechanism 4, guaranteeing the effective dispersion shearing.

[0026] Preferably, the three-stage rotary dispersion mechanism 5 includes a third rotor 51 and a third stator 52. The third rotor 51 is connected to the shaft end of the dispersion motor 1, and the third stator 52 is fixed in the dispersion cavity 21. Driven by the dispersion motor 1, the third rotor 51 and the third stator 52 rotate relative to each other. The outer side of the third rotor 51 is provided with a plurality of uniformly distributed third stirring teeth 511, and the outer side of the third stator 52 is provided with a plurality of uniformly distributed third fixing teeth 521. Both the third stirring teeth 511 and the third fixing teeth 521 are provided with three rows, one inside and one outside. A third shearing gap is formed between adjacent third stirring teeth 511 and third fixing teeth 521.

[0027] During operation, the drive motor rotates the third rotor 51, while the third stator 52 is fixed in the dispersion cavity 21. This allows for precise engagement between the third stirring teeth 511 on the third rotor 51 and the third fixing teeth 521 on the third stator 52. The high-speed, stable rotation of the third rotor 51 generates a high-frequency, intense combination of circumferential tangential velocity and angular velocity, resulting in a comprehensive kinetic energy effect. Meanwhile, the third stator 52 creates a strong, reciprocating hydraulic shearing, friction, centrifugal extrusion, and liquid flow collision effect within the third shearing gap, achieving three-stage emulsification and dispersion of the ink. Both the third stirring teeth 511 and the third fixing teeth 521 are arranged in three rows, ensuring the ink undergoes three dispersion shearing processes within the three-stage rotating dispersion mechanism 5, guaranteeing effective dispersion and shearing.

[0028] Preferably, the sidewalls of the first stirring tooth 311 and the first fixed tooth 321 form angles with the rotation axis of the first rotor 31; the sidewalls of the second stirring tooth 411 and the second fixed tooth 421 form angles with the rotation axis of the second rotor 41; and the sidewalls of the third stirring tooth 511 and the third fixed tooth 521 form angles with the rotation axis of the third rotor 51. By adopting the above-mentioned arrangement of the first stirring tooth 311, the first fixed tooth 321, the second stirring tooth 411, the second fixed tooth 421, the third stirring tooth 511, and the third fixed tooth 521, the contact area between each stirring tooth and each fixed tooth and the ink is increased, ensuring the dispersion and shearing effect of the ink.

[0029] Preferably, the device also includes a cooling box 6 and a connecting shaft 7. The shaft end of the dispersing motor 1 is connected to the end of the connecting shaft 7, which passes through the cooling box. The cooling box 6 has a circulating water inlet and a circulating water outlet. The first rotor 31, the second rotor 41, and the third rotor 51 are all connected to the connecting shaft 7. Thus, by setting the connecting shaft 7, the rotation of the dispersing motor 1 can simultaneously drive the rotation of the first rotor 31, the second rotor 41, and the third rotor 51, ensuring that the ink forms a high-pressure liquid flow inside the dispersing cavity 21. By having the connecting shaft 7 pass through the cooling box 6, a cooling effect is provided for the connecting shaft 7 and the dispersing box 2, preventing overheating of the equipment during the dispersion process.

[0030] Preferably, the device also includes a mounting base 8 and pulleys 9. The dispersing motor 1, cooling box 6, and dispersing box 2 are all mounted on the mounting base 8, and the pulleys 9 are located at the bottom of the mounting base 8. By providing pulleys 9 at the bottom of the mounting base 8, the movement of the dispersing device is facilitated.
