In the prior art, in order to solve the problem of pollution and waste caused by the foamability of the ink due to overlarge surface tension in high-speed ink dispersion, the ink is often dispersed in a sealed container, but for a large-quantity ink unit, laminar flow can not be mutually dispersed and dispersed, as the problem is provided, when a rotating shaft is eccentrically arranged, the condition of uneven surface tension is easy to generate during ink dispersion, and excessive loss is generated for a motor, and the application provides the following technical scheme based on the problem:

as shown in fig. 1-2, a high-speed dispersion machine includes a power machine base 1 and a stirring barrel 2 disposed at the bottom of the power machine base 1, a main shaft arm 3 for rotation dispersion is driven at the bottom of the power machine base 1, a secondary shaft arm 4 is fixed on the circumferential wall of the main shaft arm 3, an eccentric dispersion assembly 5 is rotatably connected to the end of the secondary shaft arm 4, and a dispersion disc 6 is fixed at the bottom of the main shaft arm 3.

Referring to fig. 3, the eccentric dispersing assembly 5 includes a sleeve 501 and a bottom plate 503 fixed at the bottom of the sleeve 501, dispersing blades 502 are equidistantly distributed on the circumferential wall of the sleeve 501, the dispersing blades 502 are spirally fixed on the circumferential wall of the sleeve 501, the bottoms of the dispersing blades 502 are fixed with the bottom plate 503, and a through hole 504 is further formed at the bottom of the bottom plate 503 between the two dispersing blades 502.

Referring to fig. 4, the bottom of the auxiliary shaft arm 4 is further provided with an inward concave groove 401, the bottom of the groove 401 at the bottom of the auxiliary shaft arm 4 extends outward to form a sleeve column 402, the bottom of the sleeve column 402 sequentially passes through the sleeve 501 and the bottom plate 503, and a baffle 403 for limiting the axial movement of the sleeve 501 is formed when the bottom of the bottom plate 503 is located.

According to the structure, when the power machine base 1 drives the main shaft arm 3 to rotate at a high speed, the auxiliary shaft arm 4 rotates synchronously, the dispersing blade 502 and ink in the stirring barrel 2 move mutually under the driving of the main shaft arm 3, the dispersing blade 502 rotates by utilizing the fluctuation of the ink, the effect of strengthening stirring in the ink is realized, the auxiliary shaft arm 4 is not coaxial with the main shaft arm 3, and the laminar flow dispersing effect can be achieved when a large amount of ink is dispersed once;
