目的 研究在设计吨袋包装机料仓时计算料仓设计额定容量大小的方法。 方法 通过分析、简化包装机的工作过程和整个工作循环中料仓内物料量变化趋势,研究料仓在正常工作中应满足的要求和料仓内物料最大量,从而根据料仓内最大物料量设计料仓额定容量。 结果 包装机料仓内最大物料量取决于料仓进料速度、排料速度以及包装规格等参数,在连续正常工作中料仓内物料最大量与料仓进料速度、排料速度和包装规格等参数存在确定的关系,可根据已知的料仓进料速度、排料速度和包装规格等参数求得料仓最大物料量。 结论 在保证料仓连续稳定供料且不出现溢料的条件下,提出了一种设计料仓额定容量的计算方法,由此可求得包装机料仓的设计额定容量。

Objective To study the method of calculating the designed hopper rated capacity of ton bag packing machine when designing its hopper. Methods By analyzing and simplifying the work process of the packaging machine and the change trend of granular materials in the hopper during the whole working cycle, the requirements to be fulfilled by the hopper and the maximum amount of material in the hopper were studied, and the hopper rated capacity was designed based on the maximum amount of material in the hopper. Results The maximum amount of material in the hopper depended on the feeding rate, the nesting rate and the packaging specifications,and there were clear relationships among them. Therefore, the maximum amount of material in the hopper could be calculated based on the known parameters such as feeding rate, nesting rate and packaging specifications. Conclusion Under the prerequisite of ensuring the continuous and stable nesting of the hopper and avoiding overflow, a method was proposed for the calculation of designing hopper rated capacity, through which the designed rated capacity for the hopper of packing machine could be calculated.
