The utility model discloses a mixing device for the production of engineering plastics. The unloading motor drives the closed ring plate to flip, and unloads the weighed raw materials, which can realize quantitative unloading and improve the convenience of unloading. The driving motor drives the rotating rod to rotate through the flange, and at the same time, the linkage sleeve is driven to rotate through the card strip and the card slot, and the stirring rod is driven to rotate, which effectively stirs the raw materials and improves the mixing efficiency. The piston and the telescopic rod in the telescopic groove move up, thereby driving the linkage sleeve and the closing plug to move up, opening the discharge pipe, and discharging the mixed materials. The whole device can both mix and close and open the discharge pipe, improving the overall convenience of use;

[0004] The above patent still has the following deficiencies: (1) There is a defect of uneven material pouring.
