Description

Technical Field

[0001] The invention relates to the technical field of water-based high-temperature resistant coatings, and in particular to a method and a device for preparing a water-based high-temperature resistant coating for a motorcycle wheel hub. Background Art

[0002] At present, in the production of motorcycle wheels, it is usually necessary to paint the wheels. Water-based paint can play a decorative role and can also provide anti-corrosion protection for the wheels. However, when producing water-based paint, the water-based paint needs to be dispersed and stirred using a stirring device to mix the various components. However, the traditional method mostly uses a stirring blade to rotate and stir. When the water-based paint is stirred by the stirring blade to produce a vortex, there will also be a stratification problem. Specifically, the concentration of the upper solution is small, and the concentration of the lower solution is large, which will affect the quality of the paint after use.

[0003] In the prior art, the side receiving column is impacted by the impact ball while rotating, and the mechanical energy of the impact ball is converted into elastic potential energy of the side spring piece and the butterfly-shaped vibration piece, so that the side spring piece and the butterfly-shaped vibration piece vibrate up and down at the same time, and then the vibration amplitude is increased by utilizing the gravity of the side vibration rod, so that the paint can be stirred vertically.

The output end of the fourth motor 32 is located inside the box 1. The plurality of stirring plates 33 are sequentially distributed around the output end of the fourth motor 32. When the fourth motor 32 is started, the stirring plates 33 are driven to rotate to mix the raw materials.

At the same time, the check valve 14 can prevent the raw materials from flowing back in the reflux pipe 13. At the same time, the circulation pump 10 is started to blow the raw materials in the bottom area of ​​the casing 1 upward to prevent a large amount of dispersed raw materials from accumulating on the inner bottom wall of the casing 1.
