Description

Planetary dispersing three-shaft mixer

The present invention relates to a mixer, in particular to a planetary type with a high-speed shaft and a fast-speed uniformly dispersed particle agglomeration and a slow-speed shaft intersecting and tangentially mixing and kneading, so as to mix and run the raw material particle agglomeration to achieve a good dispersion effect and improve production efficiency. Dispersing three-shaft mixer.

The types and uses of conventional mixers vary depending on the purpose of use, but they are all equipped with buckets. After loading materials, a stirring blade is installed on a main shaft for mixing to achieve the purpose of uniform dispersion of powder and materials. However, with the advancement of technology, the demand for powder, material renewal and the variety of materials is different from the previous situation, for the mixer all the time. The relative requirements of the role are much higher, and the conventional mixer can only meet the general requirements. The requirements for larger and finer dispersion and how to make products with the same quality at the same time are being tested. Users must seek breakthroughs, so the multi-shaft planetary mixer was developed. Generally, the mechanical high-speed mixing speed in the market is between 600rpm and 7200rpm, and the belt is used for operation, including the belt adjuster, but the belt is easy to operate for a long time.

Moreover, the space of the box is narrow, the belt adjuster is not easy to install, and the belt idler is easy to fail, which will affect the production and cause the risk of production stoppage. Moreover, it is generally known that the center of the four-axis arm of the planetary dispersed four-axis arm mixer is a diamond, and each axis is responsible for one-sixth of the installation space, but because the bearing installation space is narrow, the shaft center is small and it is easy to shake. The dynamic load bearing of the bearing is weak. The shaft center is easily deformed and bent, and the high-speed dispersing blades are afraid of colliding with the slow-speed blades due to insufficient space, resulting in poor dispersion effect and low efficiency. In addition, the center of the two shaft arms of the conventional planetary dispersing two-shaft arm mixer is generally in a line shape, and the high-speed dispersing occupies The barrel diameter area ratio is two-fifths, the space is large for the bearing, the shaft center is enlarged and enlarged, so it is not easy to shake, the dynamic load of the bearing is strong, the shaft center is not easy to deform and bend, and the dispersing blades can also be increased and dispersed, but due to the high and slow speed Shape, the slow shaft only mixes without kneading, the blank convection on both sides can only operate by revolution, and the dispersion effect is inefficient.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the inventor of the present invention and related manufacturers in the industry are eager to research and improve.
