设计简介
摘 要
粉末料填充问题在国内外应用都非常广泛,例如胶囊填充、炸药填充、粉末成型等。但现在大多数粉末料填充无法实现自动化流水线生产,很多依然需要人工装填容器,并且完成后也需人工取出。而有些粉末料成型机只是单纯的对粉末料进行上下两端加压成型,受力不均匀导致成型的产品内部依然是粉末料。本次论文主要设计的是将粉末料填入圆柱形容器中并加压使粉末料被均匀的压实。为此共设计了四个步骤,既校正容器、容器传送、填粉压粉和成品送离。校正容器是通过二阶段校正将装填粉末料的圆柱形容器以口向上的方式固定住,以便之后的操作。容器传送和成品送离是通过双轨V带轮将固定住得容器送至填粉压粉处,并在填粉压粉结束后将成品送离。填粉压粉则是通过由升降支柱带动的螺旋形填粉器与升降轨道之间的配合,使粉末料能够填入容器中并均匀的压实。实现自动化生产。

Abstract
Powder material filled in the application at home and abroad are very wide , such as capsule filling , explosive filling, powder molding . But now most of the powder material filling can not be achieved automated production lines , many still require manual loading container , and after the completion of the need to manually remove the . Some powder metal forming machine simply the powder material compression molding of the upper and lower ends , the uneven force evenly inside the molded products still powder material .The paper is designed primarily powder filling and pressurized cylindrical container of the powder material is uniform compaction . To this end were designed in four steps correction container , container shipping , fill powder pressed powder and finished to send from . Correction container is filled through a two-stage correction of the cylindrical container of the powder material to hold the mouth up , so that after the operation . Container delivery and finished to send from two-track V pulley fixed container sent to the powder filling the pressed powder and finished after the end of the powder filling pressure powder sent from . Powder filling pressure powder is driven by lifting pillar spiral fill with powder and lift between tracks , the powder material to fill the container and uniform compaction . Automated production.
