Description
図1〜図9に,本発明による押出成形装置の一実施の形態を示す。
前記スクリュー型押出機2は,混合原料25,例えば,木質合成粉の原料である木粉,樹脂,顔料,強化剤の混合物を溶融し,ゲル化混練した後,冷却,破砕,整粒して成る原料ペレット26a及び発泡剤26b,並びに必要に応じて他の添加剤を所定の配合比で配合したものを加熱混練して溶融可塑化し,この溶融可塑化した成形生地25aを押し出すスクリュー5を備える押出機である。
押出ダイ10は,スクリュー5の先端から押し出された成形生地25aを整流すると共に,成形生地25aに所望の断面形状を付与するものであって,バレル3の先端側にボルト等によって着脱可能に取り付けられている。
ブレーカープレート12は,図2〜図5に示すように,周面が小径部12aと大径部12bの2段に形成される円板状をなすものであって,押出方向後方(図2の紙面裏面側)がスクリュー5方向に配置され,押出方向前方(同図紙面表面側)が後述する成形ダイ15方向に配置されるように,バレル3の先端側に取り付けられている。
成形ダイ15は,押出ダイ10の押出孔11の出口部11bのブレーカープレート12を介して押し出された成形生地25aを更に整流すると共に,所望の断面形状を付与するものであって,図1に示すように,押出ダイ10の押出孔11の出口部11bにボルト等によって着脱自在に取り付けられている。
成形ダイ15の入口部15aには中子20が設けられている。
原料ペレット
この木質合成粉製造ライン40は,溶融ミキサー30と,冷却ミキサー31と,整粒機32と,バッファタンク33とから成り,発泡木質合成成形品製造ライン60は,ブレンダー34と,本実施の形態による押出成形装置1と,引取機35とをそれらの順に配置したものである。
そして,図1に示すように,押出成形装置1の押出機2のバレル3内にホッパ4を介して混合原料25を供給し,駆動源の作動によってスクリュー5を回転駆動させ,ホッパ4からバレル3内に混合原料25を供給し,加熱手段の作動とスクリュー5との協働により,混合原料25を加熱混練しながらスクリュー5のスクリュー部5bの溝5cに沿ってスクリュー5の先端方向に押出力を加えて圧送し,溶融可塑化した成形生地25aに形成する。
