Related to the machine.

従来この種の二軸スクリュウ式押出成型機として、一方側部に被処理物の投入部を設けると共に他方側部に排出部を設けてなるケーシングと、ケーシング内にその螺旋状の羽根部が互いに重なり合った状態で回転自在に並設された一対のスクリュウ軸と、一対のスクリュウ軸を咬合方向に回転させる駆動機構と、ケーシングの排出部に設けられ、一対のスクリュウ軸の咬合回転により混練圧縮移送されてくる被処理物を排出する複数個の排出口部をもつダイスプレートとからなる構造のものが知られている。

Japanese Patent No. 3921614

しかしながら上記従来構造の場合、上記被処理物は一対のスクリュウ軸の咬合回転により混練圧縮移送されながら上記ダイスプレートの複数個の排出口部より排出され、このとき、被処理物はダイスプレートの内面に圧摺接され、被処理物が各種の廃棄物であることも相俟って、被処理物の圧摺接によりダイスプレートの内面の摩耗が激しく、そして、過度に摩耗損傷したときには、新たなダイスプレートに交換したり、摩耗したダイスプレートを取り外して肉盛補修をして対処しなければならず、これらの対処により被処理物の処理能率の低下を招くことがあると共にダイスプレートは製作コストが高く、それだけ、経済性に劣ることがあるという不都合を有している。   However, in the case of the conventional structure, the object to be processed is discharged from the plurality of discharge ports of the die plate while being kneaded and compressed and transferred by occlusal rotation of a pair of screw shafts. In combination with the fact that the object to be processed is various kinds of waste, the inner surface of the die plate is heavily worn due to the object being pressed and is damaged excessively. It is necessary to replace the die plate with a new one or remove the worn die plate and repair the build-up. These measures may lead to a decrease in the processing efficiency of the workpiece and the die plate is manufactured. The cost is high and the cost is inferior.

本発明はこれらの不都合を解決することを目的とするもので、本発明のうちで、請求項１記載の発明は、一方側部に被処理物の投入部を設けると共に他方側部に排出部を設けてなるケーシングと、該ケーシング内にその螺旋状の羽根部が互いに重なり合った状態で回転自在に並設された一対のスクリュウ軸と、該一対のスクリュウ軸を咬合方向に回転させる駆動機構と、該ケーシングの排出部に設けられ、該一対のスクリュウ軸の咬合回転により混練圧縮移送されてくる被処理物を排出する複数個の排出口部をもつダイスプレートとからなり、上記ダイスプレートと上記ケーシングとの間に上記複数個の排出口部に合う排出穴をもつダイスライナーを交換自在に設けてなることを特徴とする二軸スクリュウ式押出成型機にある。   The present invention aims to solve these disadvantages. Among the present inventions, the invention according to claim 1 is characterized in that an input portion for a workpiece is provided on one side and a discharge portion is provided on the other side. A pair of screw shafts rotatably arranged in a state where the spiral blade portions overlap with each other in the casing, and a drive mechanism for rotating the pair of screw shafts in the occlusal direction. A die plate having a plurality of discharge ports for discharging the workpiece to be kneaded and compressed by the occlusal rotation of the pair of screw shafts. A two-screw screw type extrusion molding machine characterized in that a die liner having a discharge hole that fits the plurality of discharge openings is exchangeably provided between the casing and a casing.

又、請求項２記載の発明にあっては、上記排出口部に固化成型用の適宜長さ及び適宜内径をもつ排出ノズルを突設してなることを特徴とするものであり、又、請求項３記載の発明は、上記ダイスプレートに上記ダイスライナーを介して該ダイスプレートから突出する上記一対のスクリュウ軸の突出部を軸受する軸受部を設けてなることを特徴とするものである。   The invention according to claim 2 is characterized in that a discharge nozzle having an appropriate length for solidification molding and an appropriate inner diameter is projected from the discharge port portion. The invention according to Item 3 is characterized in that the die plate is provided with a bearing portion for bearing the protruding portions of the pair of screw shafts protruding from the die plate via the die liner.

本発明は上述の如く、請求項１記載の発明にあっては、ケーシング内に被処理物を投入部から投入すると、ケーシング内の一対のスクリュウ軸の咬合回転により被処理物は移送空間で混練圧縮移送され、ダイスプレートの複数個の排出口部から排出され、移送空間での混練圧縮移送及びダイスプレートによる摩擦抵抗により被処理物は減容されつつ加熱され、この加熱により被処理物内に含まれている樹脂分等が溶融し、樹脂分等がバインダーとなり、被処理物は排出口部から固化成型されて排出されることになり、この際、上記ダイスプレートと上記ケーシングとの間に上記複数個の排出口部に合う排出穴をもつダイスライナーを交換自在に設けてなるから、一対のスクリュウ軸の咬合回転により移送空間で混練圧縮移送されてくる被処理物はダイスライナーの内面に圧摺接されて排出穴を介して排出口部に送出され、この被処理物の圧摺接や送出によりダイスライナーの内面や排出穴の入口部分が過度に摩耗損傷したとき、ダイスライナーを新たなダイスライナーに交換することができ、このため、ダイスプレートを交換したり、肉盛補修したりすることがなくなり、それだけ、被処理物の処理能率を向上することができると共に、ダイスライナーはダイスプレートに比べて製作コストが低いため、経済性を向上することができる。   As described above, according to the first aspect of the present invention, when an object to be processed is introduced into the casing from the input portion, the object to be processed is kneaded in the transfer space by the occlusal rotation of the pair of screw shafts in the casing.

Is pressed against the inner surface of the die liner and sent to the discharge port through the discharge hole, and the inner surface of the die liner and the inlet portion of the discharge hole are excessively worn and damaged due to the pressure contact and feeding of the workpiece. When the die liner can be replaced with a new die liner, it is not necessary to replace the die plate or repair the build-up so that the processing efficiency of the workpiece can be improved. At the same time, since the die liner is lower in production cost than the die plate, the economic efficiency can be improved.

又、請求項２記載の発明にあっては、上記排出口部に固化成型用の適宜長さ及び内径をもつ排出ノズルを突設してなるから、放冷固化成型時間を確保することができ、被処理物の固化成型を良好に行うことができ、又、請求項３記載の発明にあっては、上記ダイスプレートに上記ダイスライナーを介してダイスプレートから突出する上記一対のスクリュウ軸の突出部を軸受する軸受部を設けてなるから、駆動機構側の軸受と軸受部とでスクリュウ軸を両持ち状態で支持することができ、スクリュウ軸の芯ぶれ回転による羽根部やケーシングの損傷を抑制することができると共に消費電力を低減することができる。   Further, in the invention described in claim 2, since the discharge nozzle is provided with a discharge nozzle having an appropriate length and an inner diameter for solidification molding at the discharge port portion, it is possible to secure a cooling solidification molding time. The object to be processed can be solidified and molded. In the invention according to claim 3, the pair of screw shafts projecting from the die plate through the die liner on the die plate.
