Description
なお、従来技術のようにフライトの全体を厚くするのではなく、フライトの一部のみを厚くするので、従来技術よりも製作が容易である。
図1〜3を参照しつつ、本発明の一実施形態に係るローラダイ付押出機1について説明する。ローラダイ付押出機1は、混練物の押出を行う2本のスクリュ2,3と、スクリュ2,3を収容するチャンバ4とを有する。チャンバ4の前方には上下一対のローラ9,10が配置される。チャンバ4とローラ9,10との間には、スクリュ2,3により押出された混練物の溜まり部11が設けられている。ローラ9,10は、互いに逆方向に回転するように連結される。なお、ローラ9,10は、ローラダイと呼ばれている。
フライト7の先端部であって且つフライト7の回転方向R裏側に、フライト拡厚部としてのリブ8が設けられたスクリュ2に関し、二次元の流動解析を行った。
チャンバ4の内径:Dmm
スクリュ2の軸部6の直径:0.5Dmm
リブ8が設けられていない部分のフライト7の厚みT:0.05Dmm
スクリュ2の回転数:15rpm
混練物の粘性および密度:1000Pa・s、1000kg/m
なお、比較例にかかるフライト(フライト拡厚部が先端部に設けられていないフライト)についても、本発明にかかるフライトについても、その先端部の外周面(本発明にかかるフライトについてはリブ部を含む)は、チャンバ4の内壁面4aの円弧に沿う同心の円弧形状とした。
図5に、フライト拡厚部の変形例を示している。図3,4に示したフライト拡厚部としてのリブ8は、スクリュの軸部6の中心O側に向かうにつれてリブ8の厚みが連続的に減少するように形成されている。これに代えて図5に示すリブ12(フライト拡厚部)のように、ほぼ一様な厚みのリブであってもよい。
