[0002] The reaction kettle is a core reaction equipment in process industries such as chemical industry, pharmaceutical industry and food industry, and the accuracy and stability of material feeding directly determine the product quality, production safety and raw material utilization rate. In order to improve the automation level, a weighing module is installed on the support leg of the reaction kettle in reality, and the total weight change is monitored to indirectly measure the feeding amount. The weighing equipment with anti-overturning function is widely used, mainly including an upper plate, a lower plate, a bent plate, a force transmission mechanism, a loading plate, a cushion block and a sensor, wherein the loading plate protects the equipment during transportation and installation of the weighing equipment, and is removed when the weighing equipment is used, so that the weighing equipment is in a stress deformation state.
