The present utility model relates to the technical field of twin-screw extruders, and discloses a twin-screw extruder for polymer plastics, comprising an operation table. A shell is installed on the upper part of the operation table, a first screw and a second screw are installed in the shell, a feeding port is installed on the upper part of the shell, a filter plate is installed in the feeding port, a scraper is arranged on the upper part of the filter plate, a fixed plate is installed in the feeding port, and a movable plate is arranged on the lower part of the fixed plate. In the present utility model, the movable plate moves along a first reciprocating screw rod to realize quantitative feeding of polymer plastics, which can prevent all polymer plastics from entering the channel of the extruder, avoid channel blockage and improve work efficiency. Impurities can be removed when polymer plastics pass through the filter plate, preventing impurities from entering the extruder and being mixed and processed with polymer plastics, thus ensuring product quality. The scraper moves along a second reciprocating screw rod to clean the surface of the filter plate, avoiding impurity blockage of the filter plate and improving feeding efficiency.
