【発明の詳細な説明】
この発明は双腕型混練用ニーダー（以下単にニ

従来よりこの種のニーダーは高粘度、半固体、

及びインキ業界等に広範囲に使用されている。 Traditionally, this type of kneader has been used for high viscosity, semi-solid,
Used for kneading rubber, etc. Two drive shafts each having a stirring blade are provided in the kneading tank, and the kneading is performed by rotating these shafts inwardly. It is also widely used in various rubber industries, adhesives, sealing industries, various resin industries, pigment and ink industries, etc.
しかし、この種のニーダーを使用して混練する
物質（以下被混練物という）は固形物が主であ
り、液状物にみられるごとき流動性に乏しい。 However, the materials kneaded using this type of kneader (hereinafter referred to as materials to be kneaded) are mainly solids and lack the fluidity found in liquid materials.

上方にせり上がる現象が見られ、均一に各成分が
互いに分散した被混練物が得がたい。 Therefore, the material to be kneaded is influenced by the rotational force of the stirring blade during the kneading operation and tends to rise above the stirring blade, making it difficult to obtain a material to be kneaded in which each component is uniformly dispersed in each other.

分に混練できないという欠点を有する。 To explain this problem with reference to the accompanying drawings, both the first and second drawings show a conventional kneader a, and corner portions b formed by mutually adjacent inner walls f have a right-angled shape. The kneading operation is usually performed by injecting each component (not shown) of a plurality of materials to be kneaded into a kneading tank c, rotating the drive shaft d, and moving the stirring blades e inward, that is, in the direction of the arrow in the figure. This is the work of rotating the material to knead the material to be kneaded. However, this type of kneader has the disadvantage that during the kneading operation, the material to be kneaded rises along the inner wall f, resulting in stagnation at the corner portion b, making it impossible to sufficiently knead the material.
そこでこの発明の目的は上記欠点を防止した、
即ち混練作業によつて互いに各成分が均一に分散

That is, it is an object of the present invention to provide a novel kneader that can obtain a kneaded material in which each component is uniformly dispersed through a kneading operation.
この発明の目的は特許請求の範囲に記載した事
項を実施することによつて達成できる。 The objects of this invention can be achieved by carrying out the matters described in the claims.

形成させておくと被混練物のよどみがなくなる。 The essential part of the kneader of this invention is a baffle plate provided at a corner formed by two adjacent inner walls, and the stirring blade is rotated about the center of the drive shaft of this corner. It is attached at an appropriate position from the locus of the circle to the upper edge. When attaching it, it may be integrally processed using the same material as the inner wall when manufacturing the kneader, or it may be provided separately and attached by welding or the like after manufacturing the kneader. The number of baffle plates to be attached is preferably 2 to 2 by attaching them to at least one corner out of the four corners formed on the kneader.
The solution is to provide four baffle plates. The shape of this baffle plate is formed by an upper surface, a lower surface, and three side surfaces. Of these three sides, the two sides that come into contact with the inner wall of the kneader must have a shape that matches the contact surface of the inner wall, but the remaining one side is
It doesn't matter how it looks. A typical example is a triangular prism and one in which a recess is provided on the side surface of the triangular prism that does not come into contact with the inner wall of the kneader. Preferably, if the lower surface is formed into an arc shape corresponding to the circular locus of the stirring blade, the material to be kneaded will not stagnate.

示したニーダー１であり、２は邪魔板である。 In addition, if the other side of the baffle plate that does not come into contact with the inner wall of the kneader is shaped to form a convex part in the center of the kneading tank, concave parts will be created on both sides of the convex part, which will play the same role as the conventional corner part. This is not preferable because it lowers the efficiency of stirring the material to be kneaded. Embodiments of the present invention will be described below with reference to the accompanying drawings. 3 and 4 show a kneader 1 showing one embodiment of the present invention, and 2 is a baffle plate.

いる。 FIGS. 5 to 7 show typical shapes 2a, 2b, and 2c of the baffle plates used in the present invention, and the two upper edges of the two sides that contact the inner wall of the kneader on the upper surface of the baffle plates are shown in FIGS. All of the corners formed are right-angled. 2a is made of a triangular prism, 2b has one remaining side surface 20 formed in the shape of a circular arc, and 2c similarly has one side surface formed with three planes (multifaceted). Further, the lower surfaces 9a, 9b, and 9c are all arc-shaped in correspondence with the locus 6 of the circle. In the kneader of the present invention obtained in this manner, when the components of the material to be kneaded are charged into the kneading tank and the kneading operation is carried out, the material to be kneaded does not stick to the inner wall 7 due to the presence of the baffle plate. A good material to be kneaded in which each component is uniformly dispersed can be obtained without forming any stagnation at the rising corners.
Therefore, the present invention provides a highly practical kneader that achieves the object of the present invention by simply attaching a baffle plate having an extremely simple structure to a conventional kneader without increasing costs. are doing.
