摘要：
本发明公开一种密闭式混合机的封尘结构，密闭式混合机包括：外壳和转子，混合室限定在外壳中，转子在混合室中转动用于搅拌材料，材料被填充进入混合室以在那里被搅拌。封尘结构包括：环形缸，环形缸配合到转子的转动轴并且安装在外壳开口部分的周缘，转动轴穿过外壳开口部分的周缘，缸安装在外壳开口部分的周缘处，并且适合在转动轴方向上推压配合在转动轴上的环形密封部件以阻止搅拌材料从混合室泄漏。
摘要（英）：

A dust seal structure of an internal mixer including a casing having a mixing chamber defined therein, and a rotor rotating in the mixing chamber for kneading a material, which is charged into the mixing chamber to be kneaded there, comprises a ring-shaped cylinder fitted to a rotor shaft of the rotor and mounted on a peripheral edge of an opening portion of the casing through which the rotor shaft passes, the cylinder being located at the peripheral edge of the opening portion of the casing, and being adapted to urge a ring-shaped sealing member fitted on the rotor shaft in a direction of the rotor shaft to inhibit leakage of the kneading material from the mixing chamber.
