接触式切粒需要在外力作用下使切刀紧靠模板,切刀在不同转速下需要的进刀压力不同,在不同转速下的进刀压力就形成了一条函数曲线。在更换切刀或刀轴单元检修后由于原受力状况的改变,需要对进刀曲线进行修正,以达到最佳的切粒效果。本文通过分析在接触式切粒的力学特点,介绍了进刀曲线的采集及绘制方法。 Contact pelletizing need to make the cutter close to the template under the action of external force. The cutting knife needs different feed pressure under different rotational speed. The feed pressure under different rotational speed forms a function curve. In the replacement of cutter or knife unit maintenance after the original stress due to changes in the need to amend the feed curve in order to achieve the best pelletizing effect. In this paper, by analyzing the mechanics characteristics of contact pelletizing, the introduction and drawing method of feed curve are introduced.
