称重机构

Abstract

本实用新型提供一种称重机构，涉及称量技术领域。该称重机构包括机架、称重检测件、承载件、输送组件和卸料组件，称重检测件设置于机架，用于检测待称重件的重量；承载件设置于称重检测件远离机架的一侧，承载件用于承载待称重件；输送组件设置于机架并位于承载件沿第一方向的至少一侧；卸料组件设置于输送组件，输送组件能够带动卸料组件沿第二方向运动，使卸料组件能够推动经称重检测件检测后的称重件向远离承载件的方向运动；其中，第一方向和第二方向垂直。称重检测件没有承担输送组件的重量，减少输送组件自重的影响，提高称重检测件的检测精度和适用性。同时，减少操作人员矫正和维护的操作，从而减少维护成本。
