The specific meaning of the terms in the embodiments of the present application may be understood by those of ordinary skill in the art in a specific context.

Referring to fig. 1 to 5, a multi-paddle mixing and stacking motion kneader provided in an embodiment of the present application includes: a main paddle 1, a secondary paddle 2, a third paddle 3 and a main body 4; a kneading cavity 41 is arranged in the main body 4; the main paddle 1, the auxiliary paddle 2 and the third paddle 3 are all rotatably arranged in the kneading cavity 41; the main paddle 1, the auxiliary paddle 2 and the third paddle 3 are all independently arranged.

Wherein, the independent arrangement of the main paddle 1, the auxiliary paddle 2 and the third paddle 3 means that the three are not coaxial, i.e. the axes of the three are arranged at intervals. It should be noted that the main paddle 1, the auxiliary paddle 2 and the third paddle 3 can be independently driven to be independently rotated and controlled, so as to be convenient for respectively adjusting the respective rotation speeds of the three.

Through setting up that main oar 1, vice oar 2 and third oar 3 all set up independently, can make kneading chamber 41 interior when kneading the material form changeable kneading convection current curve, reduce and knead the blind area, realize promoting and knead the effect.

Specifically, the third paddle 3 may be provided at a kneading blind area position when both the primary main paddle 1 and the secondary paddle 2 are stirring; through setting up third oar 3, can be when kneading, drive the material in the original kneading blind area to kneading the pressurized area, can increase the flow pressure of material simultaneously for the material that flows forms changeable laminar flow, realizes promoting the purpose of kneading efficiency and kneading the effect.

In one embodiment, the third paddle 3 is arranged obliquely relative to the main paddle 1 and/or the auxiliary paddle 2, i.e. the third paddle 3 may be arranged obliquely to the main paddle 1 or obliquely to the auxiliary paddle 2; also, both the main paddle 1 and the auxiliary paddle 2 may be disposed in parallel.

Specifically, the inclined arrangement of the third paddles 3 contributes to a large flow path during kneading of the material, so that the material can be kneaded more uniformly to enhance the kneading effect.

Further, the angle between the axis c of the third paddle 3 and the axis a of the main paddle 1 and/or the axis b of the auxiliary paddle 2 is smaller than 10 degrees, so that the main body 4 can be conveniently machined during production.

In one embodiment, referring to fig. 5, the profile curve formed by rotation of the third paddle 3 is tangential to the profile curve formed by rotation of the main paddle 1 and/or the profile curve formed by rotation of the auxiliary paddle 2.

Specifically, the third paddle 3 can be tangent to the main paddle 1 alone or tangent to the auxiliary paddle 2 alone, and can also be tangent to the main paddle 1 and the auxiliary paddle 2 simultaneously, so that the whole structure is compact, kneading blind areas are not easy to generate, and meanwhile, interference is not generated when the three stirring paddles rotate.

In this embodiment, the outer curved surface formed by rotating the main paddle 1 is not limited to an equal curvature curve, and may be, for example, a unidirectional cone, a bidirectional cone, or a multi-segment complementary gourd shape; similarly, the outer curved surface formed by the rotation of the auxiliary paddle 2 is not limited to an equal curvature curve; the outer curved surface formed by rotation of the third paddle 3 is not limited to an equal curvature curve.

In another embodiment, the third paddles 3 are non-equal diameter stirring bars, for example the third paddles 3 may be conical stirring bars or gourd-shaped stirring bars.

The provision of the unequal diameter third paddles 3 helps to promote material flow and further helps to create a variable kneading convection profile within the kneading chamber 41.

In one embodiment, referring to fig. 3, the third paddle 3 is located outside the perpendicular bisector of the axis line of the main paddle 1 and the auxiliary paddle 2.

In the embodiment, the axes of the main paddle 1 and the auxiliary paddle 2 are arranged in parallel; the position of the third paddle 3 outside the perpendicular bisector of the connecting line of the axes of the main paddle 1 and the auxiliary paddle 2 means that a rectangle can be obtained by adjacent the axes of the main paddle 1 and the auxiliary paddle 2, a perpendicular plane is taken along the central line of the connecting line direction of the main paddle 1 and the auxiliary paddle 2, and the third paddle 3 is not positioned on the perpendicular plane.
