[0004] Although the existing paddle mixer has good connection stability between the rotating shaft and the stirring shaft, which is conducive to a smooth stirring process, it is found in use that the angle of the stirring blade is fixed. When the blade angle gradually increases from 0-90, the axial speed of the mixing aggregate will increase within a certain angle range, but when the angle exceeds a certain value, the speed of the axial movement of the aggregate will weaken, and the speed of the circular motion of the aggregate will also decrease accordingly. The blades encounter different resistances when rotating at different angles, and different materials have different fluidities. The existing paddle mixer cannot adjust the angle of the blade according to the type of material, which is inconvenient to use. Therefore, we propose a paddle mixer that is easy to operate to solve the problem raised. Utility Model Content
