Description

Planetary dispersing three-shaft mixer

The present invention relates to a mixer, especially a planetary type with a high-speed shaft that quickly disperses particles and agglomerates and a slow-speed shaft intersects and tangentially mixes and kneads to achieve a good dispersion effect and improve production efficiency by mixing and running raw material particles to agglomerate. Disperse three-axis mixer.

The type and purpose of the conventional mixers differ depending on the purpose of use, but they are all equipped with barrels. After the materials are loaded, a mixing knife is installed on a spindle to perform the mixing work to achieve the purpose of evenly dispersing the powder and materials. However, general type mixers can be used in small quantities or with little change in material structure. However, with the advancement of science and technology, the demand for powder, materials, and materials are different from the past. The relative requirements for the role are much higher, and the conventional mixer can only meet the general requirements. The requirements for larger and more refined dispersion and how to make products of consistent quality at the same time are testing Users must seek breakthroughs, so the multi-shaft planetary mixer was developed, and the general mechanical high-speed mixing operation on the market between 600rpm and 7200rpm uses belt operation with belt adjuster, but long-term belt operation is easy to produce The belt is loose or the belt is overheated and slipped, which will cause the torque loss or malfunction, and the box space is narrow, the belt adjuster is not easy to install, and the belt idler is easy to malfunction and affect the production and cause the risk of production shutdown and maintenance. Generally, the center of the four-axis arm of the conventional planetary dispersion four-axis mixer is a rhombus, and each axis is responsible for one-sixth of the installation space. However, because the bearing installation space is narrow, the axis is small and easy to shake. The bearing dynamic load is weak, and the shaft The core is easy to deform and bend, and the high-speed dispersing blades are afraid of colliding with the slow-speed blades due to insufficient space. The dispersing effect is poor and the efficiency is low. In addition, the commonly known planetary dispersing two-axis arm mixer is in the second shaft arm The high-speed dispersion occupies two-fifths of the area of the barrel diameter. The large space is suitable for the bearing. The shaft center is enlarged, so it is not easy to shake. The bearing has strong dynamic load and the shaft center is not easy to deform and bend. The dispersion blades can also increase dispersion. , But due to the high and slow speed in-line shape, the slow shaft only mixes without kneading, and the blank convection on both sides can only be operated by revolution, and the efficiency of dispersion effect is poor.
