They are mixed in proportion according to needs to make mortar. When preparing mortar, a double-shaft zero-gravity mixer is used. At present, there are many manufacturers that develop and produce double-shaft zero-gravity mixers, and their technical strengths vary. In particular, how to solve the sealing problem of the large door of the double-shaft zero-gravity mixer. According to investigations and studies, the double-shaft zero-gravity mixer with a large door discharge method discharges cleanly without any material residue. However, in actual application, this type of large door discharge has some shortcomings, such as the large door is not tightly closed, or the large door panel of the double-shaft zero-gravity mixer is deformed and the sealing ring is aged after a certain period of use, resulting in serious powder and material leakage. For this reason, we propose a sealing device for a double-shaft zero-gravity mixer. Utility Model Content

[0009] Preferably, the support assembly includes a support block, a support plate and a limiting bolt. The support block is arranged on one side of the discharge shaft, and a support plate that cooperates with the door panel is rotatably arranged on the support block.

[0015] The utility model is provided with a discharge shaft, a support assembly, a door panel and a crank, so as to avoid the problem of loose closing in the traditional large-opening design, which leads to powder leakage. The device is driven by an air cylinder to press the door panel to the bottom plate of the dual-shaft zero-gravity mixer to achieve sealing of the discharge point. Through a large closing force, a good seal is guaranteed, powder leakage is reduced, the operation is simple, and opening and closing are simple, which increases the practicality of the device.
