The invention discloses an extrusion production line for bio-based new materials of turnover boxes. The production line includes a twin-screw extruder for bio-based material extrusion, and a feeding system is arranged above the extruder, wherein the feeding system is equipped with a bamboo powder feeding mechanism for raw material pretreatment. Different from traditional vibration screening, the mechanism adopts vortex partition propulsion screening, which reduces mechanical impact damage and equipment maintenance rate. Meanwhile, strip impurities can be discharged in real time during screening to ensure continuous and stable screening effect.
