  • Publication number: 20150122554
    Abstract: The invention provides a method for check weighing of materials and a check weighing device thereof. Accurate weighing of materials is achieved through physical deformation of a sensing device (1) caused by a vertical downward force. When the induction device (2) detects the materials, the main transmission device (30) stops rotating and the vertical downward force on the weighing device transferred to the suspension mechanism (50) through the weighing device (40). The sensing device (1) deforms under the action of vertical downward force exerted by the suspension mechanism (50) to determine the weight of materials. Comparing prior weighing readings of materials after being proportioned with weighing readings of check weighing, the main transmission device (30) drives the materials to continuously move, the process of check weighing of materials is accomplished.
