When the rotation resistance of the first stirring assembly 12 is smaller than the first preset resistance and the rotation resistance of the second stirring assembly 13 is smaller than the second preset resistance, the control system controls the first stirring assembly 12 and the second stirring assembly 13 to reversely rotate.

Alternatively, the rotation resistance of the first stirring assembly 12 and the second stirring assembly 13 is determined by detecting the load current or the torque corresponding to the first motor 14 and the second motor 15.

In the present embodiment, the first stirring member 12 and the second stirring member 13 can be controlled to rotate in the forward or reverse direction according to the amount of resistance.

In one embodiment, first, a plurality of powders are added to the kneading cylinder 11, and the plurality of powders are stirred by the first stirring member 12 and the second stirring member 13 to uniformly mix the plurality of powders. Then, a kneading solvent is added to the kneading barrel 11, and the plurality of powders and the kneading solvent are stirred with the first stirring member 12 and the second stirring member 13 to knead the plurality of powders and the kneading solvent together, to obtain a kneaded product. Subsequently, a diluting solvent is added to the kneading barrel 11, and the plurality of powders, the kneading solvent, and the diluting solvent are stirred with the first stirring member 12 and the second stirring member 13 to dilute the kneaded material, to obtain a slurry to be treated. Subsequently, the slurry to be treated is coated and dried to obtain a product of a specific shape.

The preparation process of kneading various powder and the kneading solvent and then adding the diluting solvent for dilution is adopted, so that the kneading effect of the powder and the solvent can be improved, the solid content of the slurry to be treated can be improved, the solvent in the preparation process can be saved, and the drying time of the subsequent drying step can be shortened.

In the above-mentioned production process, since the viscosity after mixing a plurality of powders with the kneading solvent is extremely large, the kneading difficulty is high. Therefore, by adopting the kneader 1 provided by the application, the bottom paddles 1213 of the first stirring assembly 12 are connected into a whole, so that the stability of the first stirring assembly 12 is improved, and the probability of deformation of the first stirring assembly 12 is reduced; and the stirring effect of the stirring members 121 on the material to be stirred is improved, thereby improving the kneading effect of the kneader 1.

For example, when the material to be stirred includes a plurality of powders, the control system controls the first stirring assembly 12 and the second stirring assembly 13 to rotate in opposite directions. Optionally, the multiple powders are materials for preparing the anode and the cathode of the battery.

For another example, when the material to be stirred includes a plurality of powders and a kneading solvent, and the viscosity of the material to be stirred is greater than a preset viscosity, the control system controls the first stirring assembly 12 and the second stirring assembly 13 to rotate in the same direction.

For another example, when the material to be stirred includes a plurality of powders and a kneading solvent, and the viscosity of the material to be stirred is less than a preset viscosity, the control system controls the first stirring assembly 12 and the second stirring assembly 13 to rotate reversely.

For another example, when the material to be stirred includes a plurality of powders, a kneading solvent, and a diluting solvent, and the viscosity of the material to be stirred is less than a preset viscosity, the control system controls the first stirring assembly 12 and the second stirring assembly 13 to reversely rotate. Alternatively, the components of the diluting solvent are the same as those of the kneading solvent.

When the material to be stirred comprises a plurality of powders and a kneading solvent, and the viscosity of the material to be stirred is smaller than the preset viscosity, the control system controls the second stirring assembly 13 to have a first rotating speed.

When the material to be stirred comprises a plurality of powders, a kneading solvent and a diluting solvent, and the viscosity of the material to be stirred is smaller than the preset viscosity, the control system controls the second stirring assembly 13 to have a second rotating speed, and the second rotating speed is larger than the first rotating speed.

For another example, when the accommodating space 11a is used for accommodating cleaning solution, the control system controls the first stirring assembly 12 and the second stirring assembly 13 to rotate reversely. Alternatively, the cleaning liquid is water, or a kneading solvent.

The foregoing has outlined rather broadly the more detailed description of embodiments of the application in order that the principles and embodiments of the application may be better understood, and in order that the present application may be better understood; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in accordance with the ideas of the present application, the present description should not be construed as limiting the present application in view of the above.
