带式输送机对电子皮带秤测量精度影响因素的研究

Research on infl uence of belt conveyor on measurement accuracy of electronic belt scale

电子皮带秤的称重精度直接影响的企业的生产效率和内部管理,通过对称重托辊进行受力分析,建立由输送带悬垂度产生的张力变化对称重托辊产生的附加力之间的数学模型,直接测量输送带悬垂度的变化得到附加力的精确值,从而得到张力变化对称重产生的影响。这对电子皮带秤测量精度的研究具有重要意义。

The measurement accuracy of the electronic belt scale directly affects the productivity and internal management in enterprises. After the force analysis of the weighting roller, the paper built the mathematical model indicating the adding force on the weighting roller caused by tension occurring due to droop of conveyance belt. By directly measuring the variation of belt droop, the accurate adding force was obtained, thus the infl uence of tension on the weighting effects was achieved. It had some signifi cance for studying the measurement accuracy of the electronic belt scale.
