The present invention relates to the field of recycled rubber preparation technology, specifically to a twin-screw extrusion device for recycled rubber. The primary technical problem addressed is overcoming the shortcomings of existing technologies, namely the tendency for desulfurization treatment to deviate and the inadequacy of cooling devices. This is achieved through the following technical solution: A twin-screw extrusion device for recycled rubber comprises: a feeding structure, a multi-stage desulfurization mechanism, and a multi-stage discharge cooling apparatus. The feeding structure includes a feed inlet, a discharge outlet, and a feed hopper, and connects to the desulfurization mechanism; The desulfurization mechanism comprises multiple interconnected twin-screw extruders, a mixing device, and a conveying device. The twin-screw extruders are connected to the mixing device, with the mixing device terminating at the conveying device. Each twin-screw extruder includes a housing and rotating screws, wherein the rotating screws are further connected to an adjustment device. This adjustment device prevents excessive tilt or displacement of the rotating screw's central shaft, thereby ensuring consistent desulfurization quality; A multi-stage discharge cooling device performs gradual cooling to prevent excessive cooling rates from compromising recycled rubber quality.
