This invention discloses a rubber component hot-melt crushing and recycling device. The crushing chamber includes two linked crushing shafts. The crushing shafts have internal cavities, and nozzles communicating with these cavities are located on their outer walls. The hot-melt chamber includes a first contraction section and a discharge section. A sleeve is rotatably mounted on the radial outer wall of the discharge section. Multiple slots are formed on the radial outer wall of the discharge section, and multiple discharge ports are formed on its axial outer wall. When the sleeve rotates relative to the discharge section, a scraper cuts the molten rubber at the discharge ports.
