The support shafts 3 penetrate through the support frame 1 and are rotatably connected thereto through bearings. A swing drive mechanism 4 is provided at the bottom end inside the support frame 1 and is located at the bottom of the mixing tank 2. The swing drive mechanism 4 is composed of a servo motor 5, a first rotating shaft 6, a second rotating shaft 7, a first cam 8, a first sprocket 9, a second cam 10, a second sprocket 11 and a chain 12.

[0022] During use, the material is mixed and stirred by the mixing tank 2. At the same time, the servo motor 5 is started, and the first rotating shaft 6 is driven to rotate by the servo motor 5. The first rotating shaft 6 synchronously drives the first cam 8 and the first sprocket 9 to rotate. The first sprocket 9 drives the second sprocket 11 to rotate through the chain 12. The second sprocket 11 drives the second rotating shaft 7 to rotate, and the second rotating shaft 7 drives the second cam 10 to rotate.
