METHOD FOR CHECK WEIGHING OF MATERIAL AND DEVICE THEREOF

摘要

The invention provides a method for check weighing of materials and a check weighing device thereof. Accurate weighing of materials is achieved through the physical deformation of the sensing device caused by a vertical downward force. The method for check weighing of materials and the check weighing device are mainly applied in check weighing of materials on a large scale with high accuracy. The vertical downward force exerted by the materials is transferred to ball-shaped components which are arranged at ends of a suspension mechanism and connected with concave brackets through rigid parts of the sensing device. The sensing device deforms under the action of vertical downward force exerted by the suspension to determine the weight of materials. Comparing prior weighing readings of materials after being proportioned with weighing readings of check weighing, the process of check weighing of materials is accomplished. Accordingly, the accuracy of check weighing of materials, in particular that of materials of a small proportion in formulas can be guaranteed, impact of external environment on the check weighing device can be lowered and quick and accurate check weighing of materials can be realized.
