For structural design stability, the upper end of the batching machine 4 is of generally circumferential design, while the aggregate weighing hopper 5 is arranged on the outer edge of the upper end of its batching machine 4. This is of course the preferred design, and in practice the shape of the upper end of the dispensing machine 4 may vary. The advantage of this design is that it can be used for dispensing any number of powders. For example, silica fume, rust inhibitor and preservative are generally most commonly incorporated. Three aggregate weighing hoppers 5 are provided at the upper end of the batching machine 4.
The aggregate weighing hopper 5 is also creatively divided into a storage hopper 7 and a weighing hopper 8. The storage hopper 7 is used for storing powder, so that the powder does not need to be filled frequently, and the storage hopper can be used for a long time after being installed once. The design of the weighing hopper 8 can then accept and weigh the powder flowing down from the storage hopper 7, and if the value is an important set value, the storage hopper 7 can stop discharging through an electric signal. At this time, the powder in the weighing hopper 8 flows into the batching machine 4 from the lower end of the weighing hopper 8. The design has the advantages that the traditional process of manually mixing the powder is completely abandoned, the powder mixing proportion is more accurate, and the whole process is more automatic.
