Uniform mixing device and method for formaldehyde-free fiberboard

The invention discloses a uniform mixing device and method for formaldehyde-free fiberboards, and belongs to the technical field of fiberboard production, the uniform mixing device comprises a reaction kettle, shaft rods rotationally mounted at the upper end and the lower end in the reaction kettle, and stirring blades located in the reaction kettle and mounted on the outer sides of the shaft rods. The first charging barrel and the liquid injection barrel are arranged on one side of the top of the reaction kettle, and the first quantitative adding assembly in the first charging barrel is controlled by the first transmission assembly to start in the stirring process of the reaction kettle, so that powder can be automatically added and filtered in the stirring process; and in addition, a liquid discharging assembly is arranged between the bottom end of the first material barrel and the bottom of the liquid injection barrel, liquid can be added in the powder adding process at the same time, synchronous operation
