(イ) 発明の分野
この発明は合成樹脂、ゴムの押出機、射出成型
機又は練製品食品類の混練に用い得る回転スクリ
ユーに関する。DETAILED DESCRIPTION OF THE INVENTION (a) Field of the Invention The present invention relates to a rotating screw that can be used for extruding synthetic resins, rubber, injection molding machines, or kneading processed food products.
(ロ) 発明の背景
従来より樹脂原料の特性を向上させるため、各
種の有機物質や無機物質を混合、混練して成型に
供されている。(b) Background of the Invention Conventionally, in order to improve the properties of resin raw materials, various organic and inorganic substances have been mixed and kneaded and used for molding.
練製品等の食品分野でも同様であり、栄養価を
高め味を向上させるために種々の粉体が混合され
る。 The same is true in the food field, such as paste products, where various powders are mixed to increase nutritional value and improve taste.
そしてこれら原料製品に対し添加物が十分撹拌
混練されるように特別な混練部を有する各種のス
クリユーの形状が開発され実用に供されている。 Various types of screws having special kneading sections have been developed and put into practical use so that additives can be sufficiently stirred and kneaded into these raw materials.
ところが、現実には混練を重視すると吐出量が
低下し、吐出量が大きくすると混練が十分に行な
えないという相反する結果となつていた。 However, in reality, when emphasis is placed on kneading, the discharge amount decreases, and when the discharge amount is increased, kneading cannot be performed sufficiently, which is a contradictory result.
吐出量を低下させないため、複数本のスクリユ
ーを用いる多軸式の混練機を使用されているが、
添加物によつては添加物が原料中に尚十分に分散
混練しない原料もあつた。 In order not to reduce the discharge rate, a multi-screw kneader with multiple screws is used.
Depending on the additive, there were some raw materials that were not sufficiently dispersed and kneaded into the raw material.
(ハ) 発明の目的

目的とする。(c) Purpose of the Invention This invention exhibits an extremely high stirring and kneading effect while appropriately releasing pressure even when mixing any additives into raw materials such as synthetic resin raw materials and edible refined product raw materials, and improves efficiency and workability. The purpose is to provide a multi-shaft kneading machine with high performance.

とを特徴とする。(d) Structure of the Invention In the multi-shaft kneading machine of the present invention, the kneading section of the kneading machine is provided with protrusions having approximately the same height as the flight height of the screws that are continuous at regular intervals along the spiral direction. A concavity is formed between the protrusions, which is deepest at the center in the spiral direction, and each protrusion is formed by a screw located at the center side of the adjacent concavity, and a plurality of screws in the kneading section are arranged in parallel. The invention is characterized in that the screws are arranged so that the protruding portions of the screws are located in the deepest parts of the recesses of the screws arranged side by side.
(ホ) 発明の効果
この発明によれば、混練部においては通常のス
クリユーフライトを無くし、螺旋方向の凹凸を定
間隔おきに形成して、各スクリユーの突出部がそ
れぞれ並設するスクリユーの凹部最深部内に位置
するようにしたので、原料にいかなる添加物が混
入されようとも、凹部内では対応する突出部で逆
流を生ぜしめるような圧縮伸展作用を連続的に繰
返し受けることになる。(E) Effects of the Invention According to the present invention, the usual screw flights are eliminated in the kneading section, and the concave and convex portions of the screws are formed at regular intervals in the helical direction, and the protrusions of each screw are arranged in parallel. Since it is located in the deepest part, no matter what kind of additive is mixed into the raw material, the concave part is continuously subjected to repeated compression and expansion actions that cause backflow at the corresponding protrusion.
従つて、原料に混入された添加物は、原料に万
遍なく分散されるとともに、十分に撹拌混練さ
れ、混練された原料は突出部側壁の移送面で螺旋
方向に移送されるが、移送面は定間隔おきの突出
部側壁により形成されるので、一部原料の逆流に
より、適度に移送圧が抜けることになり、混練効
果は一層向上する。 Therefore, the additive mixed into the raw material is evenly dispersed in the raw material, and is sufficiently stirred and kneaded, and the kneaded raw material is transferred in a spiral direction on the transfer surface of the side wall of the protrusion. Since these are formed by the side walls of the protrusions spaced at regular intervals, the transfer pressure is appropriately released due to the backflow of some of the raw materials, and the kneading effect is further improved.

The screw c has a spiral in the opposite direction to the screw 7a, and when the screw 7a in the center is driven in the X direction, the screws 7b and 7c on both sides also rotate in the directions of the arrows while meshing with each other.
前記各スクリユーの混練部６は、それぞれ螺旋

１２ａ側部に位置し、スクリユー軸の外周には60
度毎に突出部１１，１１が形成されている。 The kneading section 6 of each screw is provided with protrusions 11, 11, . Recesses 12, 12... each having a bottom surface that gradually becomes shallower from the deepest part to the protrusions on both sides are provided, and each of the protrusions 11, 11
are located on the sides of the central deepest part 12a of the adjacent recesses 12, 12, respectively, and 60 mm is located on the outer periphery of the screw shaft.
Projections 11, 11 are formed at each angle.
従つて各凹部１２，１２もそれぞれ隣接する両
側の凹部とは、60度位相をずらせた状態で配置さ

面が形成される。 Therefore, each of the recesses 12, 12 is arranged with a phase shift of 60 degrees from the adjacent recesses on both sides, and a transfer surface is formed by the side wall 13 of the protrusion.
そして、並設された各スクリユーの混練部６で

ユーの凹部１２，１２…中央最深部１２ａ内に位
置するように配設される。 In the kneading section 6 of each of the screws arranged in parallel, as shown in FIGS. 2 and 3, the protrusions 11, 11... of one screw are inside the recesses 12, 12... of the central deepest part 12a of the other screw, respectively. It is arranged so that it is located at
上述した混練部６は突出部１１，１１を螺旋方

混練部にも形成できる。 The above-mentioned kneading section 6 is of a type in which protrusions 11, 11 are provided every 120 degrees in the spiral direction, but as shown in FIG. It is also possible to form the kneading part 6 by forming the kneading part 6, and to arrange the kneading part 6 in parallel so that the protruding part 11 is located in the other screw recessed part 12.
As shown in the figure, protrusions 11, 11 are provided every 90 degrees in the helical direction to shorten the recess 12, and a kneading section can also be formed by combining these.
上述した実施例では、スクリユーを３本組合せ
たものについて説明したが、２本の組合せによつ
ても勿論本発明は構成される。 In the above-mentioned embodiment, a combination of three screws has been described, but the present invention is of course also applicable to a combination of two screws.
尚、図面第３図乃至第５図において、１４は加
熱シリンダー２の上下を連結するヒンジであり、
１５は対向側に設けた固定ボルトである。 In addition, in FIGS. 3 to 5, 14 is a hinge that connects the upper and lower parts of the heating cylinder 2,
15 is a fixing bolt provided on the opposite side.
このように構成された多軸式混練機１の投入口
３に、添加物を混入された樹脂原料又は食用練製
品原料が投入されると、まず投入口３の下部のギ
ヤー部８で原料と添加物は細かく押潰されるとと
もに、混練部６へ移送される。 When resin raw materials or edible dough raw materials mixed with additives are inputted into the input port 3 of the multi-shaft kneading machine 1 configured in this way, the gear section 8 at the bottom of the input port 3 first mixes the raw materials with each other. The additives are finely crushed and transferred to the kneading section 6.

な力で圧縮展開されることになり、一部の原料は
移送方向とは逆方向に無理に逆流させられる。 In the kneading section 6, the concave portion 12 and the protruding portion 11 that are continuously formed are subjected to repeated compression actions and expansion actions in the axial direction, but at this time, the protruding portion 11 of one screw, 11 is located at the deepest part 12a of the recess of the other screw, so the raw material in each recess 12 is compressed and expanded by a strong force, and some of the raw material is moved in the opposite direction to the transfer direction. I was forced to regurgitate the water.
しかも、移送面は連続的でない突出部側壁１３
によつて形成されているので、逆流量は比較的多
く、圧抜きしながら移送、分配、混合、逆流を繰
返して混練される。 Moreover, the transfer surface is not continuous with the protrusion side wall 13.
Since the flow rate is relatively large, the mixture is kneaded by repeating transfer, distribution, mixing, and backflow while depressurizing.
そして混練部６の終端では、原料中に添加物が
万遍なく分配され完全に混練された状態となり、
更に加熱溶融されながら後続するスクリユー部１
０によつて吐出口４まで移送される。 At the end of the kneading section 6, the additives are evenly distributed and completely kneaded into the raw materials.
The screw part 1 continues while being further heated and melted.
0 to the discharge port 4.
