Technical Field

[0001] The invention relates to the technical field of planetary mixers, and in particular to a planetary mixer for processing gel patches. Background Art

[0002] Planetary mixer is a new type of mixing equipment, suitable for various high viscosity and high solid materials. In the production and processing of gel patches, planetary mixers are usually required because gel patches often have high viscosity and planetary mixers can provide sufficient mixing force.

[0003] Planetary mixers have a unique and novel mixing form. There are usually two or three multi-layer paddle agitators and one or two automatic scrapers in the mixing tank. While the multi-layer paddle agitator revolves around the central axis of the mixing tank, it also rotates at high speed around its own axis at different speeds, causing the material to make complex movements in the mixing tank and be subjected to strong shearing and matching. Its mixing efficiency and effect are usually several times that of ordinary mixers.

[0004] For example, the structure disclosed in the Chinese patent application number CN201110401602.4, which is called a three-arm planetary stirring and kneading machine, is as follows: the frame can be a material tank lifting type, a drive unit lifting type or a gantry drive unit lifting type, and three stirring shafts evenly distributed along the circumference are used to drive three stirring devices to revolve and rotate, forming a three-arm planetary stirring and kneading machine. The material barrel can be closed and separated from the stirring device by lifting and lowering. When closed, the stirring paddles can maintain a precise gap between each other and between the stirring paddles and the inner wall of the material barrel, which greatly reduces the area of ​​the stirring dead angle and realizes high energy input.
