Description
整流体5bの挿入長さが6mm、12mm、24mmではそれぞれ、スウェル率は144%、129%、113%になる。このように整流体5bの挿入長さが長い程、スウェル率は小さくなる。ただし、この挿入長さが所定値以上になると、スウェル率はほとんど変わらないので必要以上に整流体5bの挿入長さを長くしても実益がない。

Claims (5)
- 筒状のシリンダと、このシリンダの内部空間に配置されるスクリューと、このシリンダの前端に設置されて前記内部空間と連通する押出流路を有するヘッドと、このヘッドに取り付けられて前記押出流路の前端位置で押出口を形成するダイとを備えたゴム押出装置において、
前記ダイが前記押出流路の前端位置に配置されて前記押出口の面積を変化させる方向に移動する押出口可変部材と、前記押出流路の内壁に接触した状態で前記押出流路の延在方向に移動して前記押出流路の前端側から前記押出流路に出入りする整流体とを有し、前記押出口可変部材および前記整流体をその移動方向の所望の位置に位置決めできる構成にしたことを特徴とするゴム押出装置。 - 前記整流体の後端部が、接触している前記押出流路の内壁側から前記押出流路の断面中心部に向かって前記押出流路の前方へ傾斜するテーパ形状になっている請求項1に記載のゴム押出装置。
- 対向配置された2つの前記押出口可変部材を有し、前記押出口可変部材のそれぞれが互いが近接および離反する方向に移動することにより前記押出口の面積を変化させ、前記整流体が前記押出口可変部材のそれぞれの表面に接触した状態で前記押出流路の延在方向に移動する構成にした請求項1または2に記載のゴム押出装置。
- 前記押出口から押し出されたゴム押出物の形状を検知するセンサと、このセンサの検知データに基づいて前記押出口可変部材および前記整流体のそれぞれの移動方向での位置を制御する制御部とを有する請求項1〜3のいずれかに記載のゴム押出装置。
- 筒状のシリンダの内部空間にゴム材料を投入し、この内部空間に配置されたスクリューにより、前記ゴム材料を前方に押し出しつつ混合および混練した未加硫ゴムを、前記シリンダの前端に設置されたヘッドに形成されている押出流路に送り込み、前記ヘッドに取り付けられたダイにより形成される押出口からゴム押出物として押し出すゴム押出物の製造方法において、
前記ダイが前記押出流路の前端位置に配置されて前記押出口の面積を変化させる方向に移動する押出口可変部材と、前記押出流路の前端側から前記押出流路に出入りする整流体とを有し、前記押出口可変部材をその移動方向の所望の位置に位置決めし、前記整流体を前記押出流路の内壁に接触した状態で前記押出流路の延在方向に移動させて所望の位置に位置決めして、前記未加硫ゴムを前記押出流路を通過させて前記押出口から押し出すことにより、所望の形状のゴム押出物を製造することを特徴とするゴム押出物の製造方法。
