Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to an anti-dead angle mechanism of a fire-retardant coating mixer. Background Art

[0002] Fire retardant coating is a coating that is applied to the surface of a material to improve the material's fire resistance, slow down the spread of flames, or prevent combustion for a certain period of time. This type of coating is called fire retardant coating, or flame retardant coating. Before using fire retardant coating, it needs to be mixed with water in a certain proportion, usually using a mixer.

[0003] Most of the mixers currently used do not have the function of rotating when mixing paint. When the mixer is stirring the paint, the stirring blades cannot stir the paint inside the mixing barrel in all directions, which will cause some paint inside the mixer to not be fully stirred. This will reduce the efficiency of paint use, and when the mixer is stirring the paint, it is usually stirred in the same direction. Stirring in a single direction cannot make the paint mix faster.
