Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a blade structure of a mixing mixer. Background Art

[0002] A mixer is a machine in which a shaft with blades rotates in a cylinder or a trough to mix a variety of raw materials to form a mixture or a suitable consistency. Mixers are divided into forced mixers, single-horizontal-shaft mixers, twin-horizontal-shaft mixers, etc. Blades are an indispensable structure in mixers.

[0003] Reference patent document publication number CN218516461U discloses a mixer blade structure, which relates to the technical field of mixers. The mixer blade structure comprises a fixed shaft, a first connecting member and a second connecting member, wherein one end of the first connecting member is fixedly connected to the fixed shaft, and the other end of the first connecting member is provided with a connecting groove, which fits the outer side of the second connecting member and is fixedly connected to one end of the second connecting member. The mixer blade structure is provided with a connecting groove at one end of the first connecting member, and one end of the first support plate and the second support plate are formed into a stepped shape. When the second connecting member is welded and fixed, the first mounting plate is adapted to the connecting groove at one end of the first connecting member, so that the connection is overlapped, the contact surface is increased, the stability of the connection is improved, and the welded connection between the first connecting member and the second connecting member is avoided from breaking during later use, thereby extending the service life.

[0004] Although the above scheme can enable the blades to stir the materials during use, there are still some shortcomings during use. For example, it is inconvenient to disassemble the blades during use, resulting in the material sticking to the blade surface and being difficult to clean after stirring the items with high viscosity. As a result, a large amount of material will stick to the blade surface after long-term use, which not only affects the rotation speed of the blades, but also affects the stirring effect of the raw materials. For this reason, a blade structure of a mixing mixer is proposed. Utility Model Content
