Anti-leakage oscillating granulator

The utility model relates to an anti-leakage swinging granulator, which effectively solves the problems that the product quality is influenced and equipment is damaged due to leakage in the production process of medicine granules. Comprising a machine body, a hopper is arranged at the front end of the machine body, a rotating shaft is arranged in the hopper, a roller is fixed outside the rotating shaft, a sealing cover located outside the rotating shaft is fixed to the side wall of the machine body, a sealing ring sleeving the rotating shaft is fixed to the sealing cover, and an annular groove with a triangular section is formed between the sealing ring and the sealing cover. The size of the annular groove is continuously reduced outwards from the axis of the rotating shaft; the sealing device is simple in structure, due to the existence of the annular groove, impurities such as oil dirt passing through a gap between the rotating shaft and the sealing cover can be reserved in the annular groove, the oil dirt
