This invention relates to the field of extrusion molding, specifically concerning a co-rotating conical twin-screw extruder for polyolefin extrusion foaming processing. It comprises a frame and a rotational control device. The frame includes a barrel and a conical screw, with the barrel fixedly mounted on the frame. The conical screw is rotatably installed within the barrel. The rotation control device comprises a clutch assembly, a linear drive assembly, a rotational drive assembly, and a synchronous transmission assembly. The clutch assembly includes a mounting base, a mating ring, a first rotary shaft, a mounting ring, protrusions, and a first elastic member. The mounting base is fixedly mounted on the conical screw. The mating ring is fixedly mounted on the mounting base. The first rotary shaft is rotatably mounted on the frame. The mounting ring is fixedly mounted on the first rotary shaft. Multiple protrusions and first elastic members are provided. The protrusions are slidably mounted on the mounting ring. Both ends of the first elastic member are fixedly connected to the mounting ring and the protrusions, respectively. This invention enables flexible control over the start and stop functions of the tapered screw, preventing overall system stagnation during machining.
