The invention relates to an inorganic filler side feeding device for a screw extruder. The side wall of a raw material unheated section of the screw extruder is connected with a discharge port of a filler feeder, and filler and master batch fed from a feed port of the screw extruder are mixed at the section. According to the invention, a powder material can be directly and uniformly mixed with raw materials (synthetic resin and other assistants) in the charging barrel of the screw extruder through a feeding machine, so that the use of a dispersing agent is avoided, the mixing time is shortened, and the production cost is reduced. 本发明涉及一种用于螺杆挤塑机的无机填料侧喂料装置。在螺杆挤塑机的原料未加热段的侧壁连接填料喂料机的出料口，填料与从螺杆挤塑机进料口投入的母料在此段混合。本发明可直接将粉体材料通过喂料机与原料(合成树脂和其它助剂)在螺杆挤塑机的料筒内均匀混合，避免了分散剂的使用，减少了混合时间，降低了生产成本。
