The present utility model belongs to the technical field of extruders, and provides a twin-screw extruder for EPDM foam production, comprising a device bottom plate and a device main body arranged above the device bottom plate. An extrusion block is arranged on the outer wall of one side of the device main body, two first moving slots are formed on the outer wall of the extrusion block, a first motor is fixedly connected to the outer wall of one side of the extrusion block, a bidirectional threaded rod is arranged on the inner wall of one of the first moving slots, the output end of the first motor is fixedly connected with the bidirectional threaded rod, and two moving blocks are symmetrically arranged on the inner wall of the first moving slot. When an operator needs to extrude the foam raw material out of the device, the operator first starts the first motor to drive the bidirectional threaded rod to rotate, which drives the two moving blocks to move, so that the waste scraper plate drives the adjustment patch to move. This can block the discharge slot, prevent the discharge slot from being blocked and resulting in inconvenient discharging. The device can precisely control the extrusion output of the raw material, prevent the blockage of the discharge port, and realize convenient discharging.
