[0002] Stirring devices play an important role in many industrial fields, such as chemical industry, food processing, pharmaceutical industry, etc. In order to achieve high-precision control of stirring equipment, improve production efficiency and product quality, servo motors are widely used in stirring equipment. Servo motor control has the characteristics of fast response, high-precision control and good stability, enabling the stirring device to achieve more precise control and higher production efficiency.

[0003] However, there are various types of stirring devices in the prior art. For example, the utility model patent CN206899507U relates to a stirring device for calcium silicate board raw materials. The utility model includes a stirring barrel, the bottom end of the stirring barrel is funnel-shaped, and a discharge pipe is provided at the bottom end. The bottom end of the stirring barrel is also provided with support feet. A servo motor and a feed inlet are provided at the top end of the stirring barrel. A stirring shaft is provided at the center of the inner part of the stirring barrel. The upper end of the stirring shaft penetrates through the top of the stirring barrel and is fixedly connected with the main shaft of the servo motor. Stirring blades are arranged at intervals on the stirring shaft.
