A feeding port is provided on the upper right side of the stirring box, and a discharging port is provided on the lower right side of the stirring box. The utility model is provided with a cleaning plate and a rotating rod. The stirring blade stirs while driving the rotating rod to rotate, so that the cleaning plate rotates in close contact with the stirring box. The residual raw materials in the inner wall of the stirring box can be scraped and brushed to prevent the raw materials from remaining on the inner wall of the stirring box. The inner wall bottom end of the stirring box is designed as a slope, which can assist the raw materials to flow out of the discharging port and prevent corner residues. However, the stirring mechanism is uniformly distributed vertically. The driving mechanism at the top stirs the entire vertically uniform stirring mechanism. The stirring mechanism at the bottom has high energy consumption, and a large driving force is required to conveniently drive the entire vertically uniform stirring mechanism. Moreover, the top of the stirring mechanism is prone to breakage during stirring. Therefore, a raw material stirring device for plastic production is designed, which has a stirring mechanism that can reduce the stirring driving range according to the distance from the stirring driving mechanism, has high stirring driving stability, and has a long service life.
