Description

Planetary three-shaft mixer

The present invention relates to a mixer, especially a planetary three-shaft mixer with a small intersecting and tangential distance to easily produce extrusion shear and high-efficiency dispersion effects.

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, material updates, 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 quantities and finer dispersion and how to make products of consistent quality at the same time are testing Users must seek breakthroughs. Therefore, multi-shaft planetary mixers have been developed. Generally known planetary three-shaft mixers mainly have three-arm rotation and rotation, and six helixes are tangent to the self-running type, which is the same as the rotation and rotation. Two arms are staggered, one arm is not staggered, and the four helixes are tangent, and the three arms of the revolution and rotation are not staggered and the six helixes are tangent, and the three arms of the same size do not intersect and do not overlap. The large-angle cutting edge must keep a large intersection distance when the two arms are interlaced, otherwise it is easy to produce collisions, and in solvent-based materials, it is easy to produce sparks or damage the mechanical structure, and because it is necessary to reserve a large intersection space, so The raw material particles pass through the tangent gap, which leads to poor dispersion efficiency, and the larger the intersecting space, the more dead corners of stirring and the worse the mixing effect. However, the two arms of revolution and rotation are staggered, and one arm is not staggered. The two arms of the four-helix tangent type with the same size intersect and overlap, and one arm does not intersect and does not overlap. The large-angle cutting edge must keep a large intersection distance when the two arms intersect, otherwise it is easy to cause collision In solvent-based materials, it is easy to produce sparks or damage the mechanical structure. Also, because of the need to reserve a larger intersection space, the raw particles pass through the tangent gap, which leads to poor dispersion efficiency, and the larger the intersection space, the The more dead corners of agitation, the worse the effect of agitation and kneading.
