The movement of the two-way hinge shaft causes the push-pull rod to move downward, thereby conveying the ingredients from the feeding barrel to the mixing barrel. When the mixing ratio reaches the preset value, the ingredients enter the mixing barrel through the conveying pipe and are mixed by the high-speed rotation of the stirring blade.
