The feeding assembly can introduce the elastomer melt into the hot melt box 1. The granulation assembly includes a gear pump 4 fixedly connected to the bottom wall of the hot melt box 1. The input end of the gear pump 4 penetrates the bottom wall of the hot melt box 1 and communicates with the inner cavity of the hot melt box 1. A granulation box 5, with an open bottom structure, is fixedly connected to the bottom of the gear pump 4, penetrating the top wall of the granulation box 8. A granulation nozzle 6 is fixedly connected to the top of the granulation box 5. The input end of the granulation nozzle 6 penetrates the granulation box 5 and communicates with the output end of the gear pump 4. The granulation assembly can granulate the elastomer melt. The collecting drawer 9 is sliding against the inner wall of the granulation box 8. The bottom wall of the collection drawer 9 is equipped with a filter screen plate 10, and the inner cavity of the collection drawer 9 is equipped with a sieve screen plate 11. Several vibrating motors 12 are arranged at equal intervals at the bottom of the sieve screen plate 11. The collection drawer 9 can collect particles, and the cooperation between the vibrating motors 12 and the sieve screen plate 11 can sieve the particles after granulation, thus separating particles that do not meet the specifications from particles that meet the specifications, so as to ensure the overall quality of the particles. The cooling component includes a liquid guide pipe 13.
