    • The present invention relates to an apparatus for manufacturing foamed thermoplastic resin pellets and method thereof. The manufacturing apparatus includes a cylindrical dice, a plurality of extrusion holes formed along a radial direction of the dice and communicated with a resin flow path formed at the dice, a guide symmetric with the extrusion holes and protrudingly formed at the whole or a portion of outer circumference surface along the longitudinal direction of the dice, an operation member slidably installed along the guide, and a cutting knife with penetration holes being formed along the longitudinal direction of the knife and being communicated with the extrusion holes, wherein both ends of the knife are fixed at the upper edge of the facing planes of the operation member, and its center in the traverse direction is downwardly curved such that it is contacted with the contact line of the extrusion holes. A foaming-rate regulating member is installed at the outer circumference surface of the dice.
    • 本发明涉及一种发泡热塑性树脂粒料的制造装置及其制造方法。 制造装置包括:圆筒状的骰子,沿着骰子的径向形成的多个挤出孔,与形成在骰子上的树脂流路连通,与该挤压孔对称的导向件,突出地形成在整个或一部分 沿着骰子的纵向方向的外周表面,沿着引导件可滑动地安装的操作构件,以及沿着刀的纵向方向形成有贯穿孔并与挤压孔连通的切割刀,其中刀的两端 被固定在操作构件的面对面的上边缘处,并且其在横向方向上的中心向下弯曲,使得其与挤出孔的接触线接触。 发泡率调节件安装在骰子的外圆周表面。
