A stirring shaft 8 is vertically provided on the moving seat 6 on the upper side of the kettle body 1. The stirring shaft 8 is rotatably connected to the moving seat 6. One end of the stirring shaft 8 extends into the kettle body 1. A paddle 16 is provided at the end of the stirring shaft 8 extending into the kettle body 1. The hydraulic cylinder 5 controls the lifting of the moving seat 6. The lifting of the moving seat 6 drives the lifting of the stirring shaft 8. The stirring shaft 8 drives the paddle 16 to lift in the kettle body 1, realizing the simultaneous lifting during the stirring process, so as to adapt to the production stirring of waterborne epoxy coatings and also be applicable to the stirring when the amount of waterborne epoxy coatings in the kettle body 1 is small; A first sleeve 10 is provided on the moving seat 6 outside the stirring shaft 8. The first sleeve 10 extends into the kettle body 1. The first sleeve 10 is connected to the stirring shaft 8 through a bearing 11. A second sleeve 9 is vertically provided on the upper side of the kettle body 1. The second sleeve 9 is located outside the first sleeve 10. The second sleeve 9 is coaxially arranged with the first sleeve 10. The inner diameter of the second sleeve 9 is larger than the outer diameter of the first sleeve 10. The first sleeve 10 and the second sleeve 9 are in sealed sliding connection. The first sleeve 10 and the second sleeve 9 can be sealed and connected through a sliding ring or the like. This sealing form is prior art and will not be elaborated. The sliding and rotational friction between the stirring shaft 8 and the kettle body 1 is transformed into the sliding friction between the first sleeve 10 and the second sleeve 9. At the same time, the rotation between the first sleeve 10 and the stirring shaft 8 is realized through the bearing 11, separating the sliding action from the rotational action, greatly increasing the service life of the stirring shaft 8 and the kettle body 1; One end of the moving seat 6 is provided with a motor 12. The motor 12 and the stirring shaft 8 are respectively located at both ends of the moving seat 6 and are balanced with the hydraulic cylinder 5 as the center.

The transmission device includes a driving pulley 13 provided on the output shaft of the motor 12 and a driven pulley 14 provided at the upper end of the stirring shaft 8. The driving pulley 13 and the driven pulley 14 are connected by a belt 15. The motor 12 drives the driving pulley 13 to rotate. The driving pulley 13 drives the driven pulley 14 to rotate through the belt 15. The driven pulley 14 drives the stirring shaft 8 to rotate.
[0016] A sealing packing 18 is provided between the first sleeve 10 and the stirring shaft 8 to increase the sealing performance of the kettle body 1.
[0017] A turntable 17 is axially provided on the stirring shaft. A plurality of blades 16 are annularly and spacedly arranged on the outer side of the turntable 17. The blades 16 form a certain angle with the axis of the stirring shaft 8. The optimal state is 20 degrees. Of course, it can also be other angles within the range of 15 - 30°. This can achieve a greater stirring force, with good stirring and mixing effects, and can also promote the up-and-down flow of the waterborne epoxy coating in the kettle body 1.
