Description

本発明は、ミキサーに関し特に、交互に接する際のギャップが小さく、押出し・せん断が容易で効率的に分散する効果を備える遊星式３軸ミキサーに関する。 The present invention relates to a planetary three-axis mixer, in particular, which has a small gap at the time of alternating contact, is easy to extrude and shear, and has an effect of efficiently dispersing.

従来のミキサーの種類や用途は使用目的によって異なるが、いずれもドラムを備えており、材料を装填した後、スピンドルに取り付けられた攪拌ブレードで攪拌作業を行い、粉末や材料を均一化にしてから利用するよう構成されている。
少量で材料構造もほとんど変化しない場合、汎用ミキサーは十分に使用できるが、技術の進歩に伴い、粉末や材料の更新、および材料の多様性は以前の状況とは異なり、ミキサーの役割に対する要求は高まり、従来のミキサーは一般的な要求しか満たすことができず、より大量でより細かい分散の要求と、どうすれば同じ時間で一貫した品質の製品を作成する方法については、ユーザーにとって突破口を探さなければならない問題であり、そのため、多軸遊星式ミキサーが開発された。
一般的に、従来の遊星式３軸ミキサーは、主に自公転する３本のアームが交えず６本のらせん線が接する自走式タイプと、自公転する２本のアームが交えて１本のアームが交えずに自走式で４本のらせん線が接するタイプとがあり、そのうち、自公転する３本のアームが交えず６本のらせん線が接する自走式タイプの３本のアームは、同じサイズで交えも重なりもせずにそれぞれ運行するようになり、その大角度の刃先は、２本のアームが交えるときに大きな出会う距離を維持する必要があり、そうでないと、衝突が発生しやすく、溶剤類のような材料であると、火花が容易に発生したり、機械的構造が損傷したりする傾向があり、さらに、大きな出会うスペースを維持する必要があるため、原料粒子が通過する隙間が大きく、分散効率が低下する現象が発生し、出会うスペースが大きいほど、攪拌のデッドスポットが多く、攪拌、混合効果が悪化する。
一方、自公転する２本のアームが交えて１本のアームが交えずに自走式で４本のらせん線が接するタイプの２本のアームは同じサイズで交えて、１本のアームは交えずに運行するようになり、その大角度の刃先は、２本のアームは交えるときに大きな出会う距離を維持する必要があり、そうでないと、衝突が発生しやすく、溶剤類のような材料であると、火花が発生したり機械的構造が損傷したりする傾向があり、さらに、大きな出会うスペースを維持する必要があるため、原料粒子が通過する隙間が大きく、分散効率が低下する現象が発生し、出会うスペースが大きいほど、攪拌のデッドスポットが多く、攪拌、混合効果が悪化する。 The types and uses of conventional mixers vary depending on the purpose of use, but all are equipped with a drum, and after loading the material, the stirring work is performed with a stirring blade attached to the spindle to homogenize the powder and material. It is configured to be used.
If the material structure does not change much with a small amount, the general-purpose mixer can be used well, but with the advancement of technology, the renewal of powder and materials, and the variety of materials are different from the previous situation, and the demand for the role of the mixer is. Increasingly, traditional mixers can only meet common demands, and users have to find a breakthrough in the demands of larger and finer distributions and how to create consistent quality products in the same amount of time. Therefore, a multi-axis planetary mixer was developed.
In general, a conventional planetary 3-axis mixer is mainly a self-propelled type in which three self-revolving arms are not mixed and six spiral wires are in contact with each other, and one is a combination of two self-revolving arms. There is a type of self-propelled type in which four spiral wires are in contact without crossing the arms of, and three arms of self-propelled type in which three arms that revolve around themselves are not crossed and six spiral wires are in contact. Will now operate at the same size without crossing or overlapping, and their large angled cutting edges must maintain a large meeting distance when the two arms meet, otherwise a collision will occur. Materials that are easy to handle, such as solvents, tend to generate sparks easily, damage the mechanical structure, and require the maintenance of a large meeting space, which allows raw material particles to pass through. A phenomenon occurs in which the gap is large and the dispersion efficiency is lowered, and the larger the space to meet, the more dead spots of stirring, and the worsening of the stirring and mixing effects.
On the other hand, two arms that revolve around each other are mixed and one arm is not mixed, but two arms that are self-propelled and have four spiral wires in contact with each other are of the same size, and one arm is mixed. Its large-angle cutting edge requires that the two arms maintain a large meeting distance when they meet, otherwise they are prone to collisions and are made of materials such as solvents. If there is, there is a tendency for sparks to be generated and the mechanical structure to be damaged, and further, since it is necessary to maintain a large meeting space, a phenomenon occurs in which the gap through which the raw material particles pass is large and the dispersion efficiency is reduced. However, the larger the space to meet, the more dead spots of stirring, and the worse the stirring and mixing effect.

したがって、前記の従来の問題および欠点をどのように解決するかは、本発明の発明者および当業者が緊迫に研究および改善したい方向である。 Therefore, how to solve the above-mentioned conventional problems and shortcomings is a direction that the inventor of the present invention and those skilled in the art want to study and improve urgently.

Propeller wings are fine.

３セットの攪拌ユニット４は、公転ユニット３に接続され、攪拌タンク２３１に収容され、各攪拌ユニット４は、上辺部４１および下辺部４２を有し、各攪拌ユニット４は、さらに各側辺部４３をそれぞれ有し、各側辺部４３の上端は、上辺部４１の一端に接続するように延在し、側辺部４３の底端は、下辺部４２の一端に接続するように延在する。
また、他の側辺部４３の上端は、上辺部４１の他端部に接続するように延在し、他の側辺部４３の底端は、下辺部４２の他端部に接続するように延在し、各側辺部４３は、それぞれ、側辺角４３１が形成され、側辺角４３１の角度（θ）は７０〜７８度である。各攪拌ユニット４の上辺部４１は、それぞれ、駆動モジュール２１に接続されるとともに駆動シャフト３１に組み立てられた軸心４４を有する。隣接する攪拌ユニット４の軸心４４間に軸心距離が形成され、上辺部４１の長さＤ１は、軸心距離Ｄ２よりも大きい。 The three sets of stirring units 4 are connected to the revolution unit 3 and housed in the stirring tank 231. Each stirring unit 4 has an upper side portion 41 and a lower side portion 42, and each stirring unit 4 further has each side portion.

While the stirring unit 4 is rotating, each of the stirring units 4 is driven. By designing the side angle 431 of the side portion 43 at an angle (θ) of 70 to 78 degrees, the side portions 43 of these stirring components 4 are allowed to pass alternately at the minimum distance without colliding with each other. As a result, the gap through which the agglomerates of the raw material molecules in the stirring tank 231 can pass is small, and the effect of facilitating extrusion / shearing and enhancing the dispersion effect can be obtained.
Further, by making the length D1 of the upper side portion 41 larger than the axial center distance D2, a space 441 that meets between the side portions of each stirring unit 4 is formed, and the meeting space 441 is a small triangular space and is agitated. The unit 4 is rotated in a narrow gap on the inner wall of the stirring tank 231 to reduce the formation of dead spots in the planetary 3-axis mixer 1 to improve the stirring / kneading effect, and at the same time, shorten the stirring time and the effect of good production quality.
