本文阐述了粉状物体采用聚乙烯薄膜包装时粉尘对包装速度的影响。由于影响粉状物料的包装速度的因素很复杂,因此本文重点阐述粉状物料下料后,从粉尘的沉降速度影响着包装的封接速度。从理论上分析、研究影响粉尘沉降的原因和粉状物料装填到袋后,粉尘在袋内形成蘑菇状的粉尘云的过程,以及为提高粉状物料的包装速度提出解决的方法。 This article describes the effect of dust on the packaging speed when powdered objects are packed in polyethylene film. Due to the complexity of the factors affecting the packing speed of the powdered material, this article focuses on the rate of settling of the package from the settling rate of the dust after the powdered material is blanked. From the theoretical analysis, the paper studies the reasons that affect the dust settling and the process that the dust forms the mushroom-shaped dust cloud in the bag after the powdery material is filled in the bag, as well as the solution to improve the packaging speed of the powdery material.
