透彻了解皮带电子秤的计量原理将有助于改进设计。本文介绍了皮带电子秤的计量原理,并讨论影响其精度的一些因素。一、秤体的基本结构形式从机械角度来说,皮带电子秤(以下简称皮带秤)可归结为图1所示的三种形式。 1.单托辊式这种结构形式(如图1a)的称量工作段l_e只是其中一小段,计量部分与非计量部分没有完全分开。因此,随皮带的松紧和物料的不 A thorough understanding of the measurement principle of the belt scale will help to improve the design. This article describes the measurement principle of the belt scale and discusses some of the factors that affect its accuracy. First, the basic structure of the scale body From a mechanical point of view, the belt scale (hereinafter referred to as the belt scale) can be attributed to the three forms shown in Figure 1. 1. Single-roller structure (Figure 1a) weighing the work section l_e only one of the short sections of the measurement and non-measurement of the part is not completely separated. Therefore, with the elastic belt and the material is not
