Therefore, the data measured by the weighing device 23 is the weight of the metering hopper 21 plus the discharging device 22, when the powder is filled in the metering hopper 21, the data measured by the weighing device 23 is the weight of the metering hopper 21 plus the powder added to the discharging device 22, and if the weight of the powder needs to be known, the measured weight is only required to subtract the weight of the metering hopper 21 and the discharging device 22. The weights of the measuring hopper 21 and the discharging device 22 can be measured in advance and fixed, so that a compensation rule can be set in the PLC controller 4, that is, when the PLC controller 4 receives the measurement data sent by the weighing device 23, the weights of the measuring hopper 21 and the discharging device 22 which are measured and input in advance are actively subtracted, so that the displayed weight is the weight of the powder.

If the feeding is stopped before the weight of the container reaches the set value, the feeding accuracy is also low due to the uncertainty of the weight of the powder between the storage silo and the container. In the technical scheme, the weight of the powder left in the metering hopper 21 is measured by the weighing device 23 in the discharging process to control the discharging amount, so that the powder with the required weight can be accurately placed underground, the discharging precision is ensured, and the quality of a finished product is improved; meanwhile, the discharging device 22 is directly controlled by the PLC 4 in the discharging process, so that the discharging process is more intelligent, manual operation is greatly reduced, the production efficiency is improved, and the production cost is reduced; the weighing device 23 measures the weight of the powder remaining in the metering hopper 21 in real time, and when the weight reaches a set value, a signal can be fed back to the PLC 4 in time, so that the PLC can control the discharging device 22 to be closed in time. On the other hand, the weighing device 23 measures the weight of the powder in the metering hopper 21, so that the worker can timely know whether the powder in the metering hopper 21 is sufficient or not, and judge whether the powder needs to be supplemented to the metering hopper 21 or not, and the influence on subsequent production is avoided.
