Sealing device of masticator

The utility model relates to a sealing device of a masticator. The sealing device of the masticator comprises rotor shafts, an outer shaft sleeve, an alloy sealing ring, a sleeve, an S-shaped cutting ferrule, a masticating cabin and a side plate of a masticating cabin. The sealing device of the masticator is characterized in that two groups of rotor shafts are parallely arranged and moveably arranged in the masticating cabin; the outer shaft sleeve, the alloy sealing ring, the sleeve, the S-shaped cutting ferrule and a carbon fiber sealing ring are sequentially sleeved at the rotor shaft end, respectively; and the side plate of the masticating cabin is arranged on the upper side of the masticating cabin, and rotor shaft holes are respectively arranged on both sides of the side plate and used for insertion of the two groups of rotor shafts. The sealing device is scientific and reasonable in design, low in manufacturing cost, and novel and practical, so that the working efficiency of the masticator is extremely
