The invention relates to the technical field of stuffing filling, in particular to a using method of a multi-material filling metering device. According to the using method of the multi-material filling and metering device, the multi-material filling and metering device is adopted, the multi-material filling and metering device comprises a rack component, a
servo metering component and a volume adjusting component, in the using process, a
servo driving connecting shaft drives a lead screw to rotate, a nut drives a sliding block to move forwards and backwards, and the volume adjusting component is adjusted; and the sliding block drives the
piston in the material cylinder to move through the
piston rod, so that the material cylinder performs material filling operation after sucking materials. According to the method, filling is accurate, using is convenient and fast, simultaneous filling of multiple materials through a single filling
machine can be achieved, and the equipment
purchase cost, the equipment occupied area and the labor cost are greatly reduced; and moreover, the filling
machine has a multi-range metering and adjusting function, can be driven by a
servo system, and can be matched with material cylinders with different diameters to realize range adjustment, so that high-precision filling or filling injection is realized.
