Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, and more specifically, to a high-efficiency powder coating premixing device. Background Art

[0002] When powder coatings are produced, it is necessary to first use a pre-mixing device to fully mix multiple powders. When mixing powders, existing mixing devices generally place them in a tank and stir them in one direction through stirring blades. This method will cause the powders to rotate in one direction, resulting in low mixing efficiency and a long time consumption. In addition, in some mixing devices, the motor continuously switches between forward and reverse rotation, driving the stirring blades to rotate in two directions in turn to improve the stirring efficiency. However, when the motor switches between forward and reverse rotation, the shear force on the motor output shaft and the stirring blades is large, which can easily cause the motor output shaft or the stirring blades to break.
