When the common turning plate is adopted as the valve of the discharge port of the storage tank 200, the valve 500e on the storage tank 200 is preferably closed when the powder is conveyed to the storage tank 200, especially when the powder is conveyed by adopting high-pressure air flow, so that the temporary storage tank 400 can continuously convey the material into the material mixing tank 300 in the process of conveying the material into the material mixing tank 300 through the rotating shaft 505e, the valve 500e adopted by the discharge port of the storage tank 200 can adopt a rotary valve structure shown in fig. 5 and comprises a valve housing 501e, a group of blades 502e are arranged in the valve housing 501e, the edge of the blades 502e is closely matched with the inner wall of the valve housing 501e to prevent the powder from flowing out from a gap, the rubber strip 503e is arranged at the edge of the blades as shown in the drawing, the servo motor 504e is arranged outside the valve housing 501e, the servo motor 504e is connected with the blades, the blades are driven by the servo motor 504e to rotate the blades 501e, the powder in the feeding position 506 is driven by the blades to be discharged out of the valve 507, the temporary storage tank 400 can not influence the material mixing tank 200 in the process of conveying the powder into the material mixing tank, and the material mixing tank 200 can be further improved. Moreover, the rotation speed of the blade 501e can be controlled by the servo motor 504e, so that the powder flow rate is controlled to avoid powder blocking and accumulation or excessively rapid metering inaccuracy.
In order to accurately measure the material in the material storage tank 200, as shown in fig. 6, a vibration feeder 900 is further configured at the material outlet of the material storage tank 200, the vibration feeder 900 comprises a conveying shell 901, a vibration element 902 is configured on the conveying shell 901, powder falling into the conveying shell 901 can flow into the material distribution tank 300 along a channel in the conveying shell 901 through vibration provided by the vibration element 902, on one hand, the vibration element 902 can effectively avoid material accumulation and blockage in the conveying shell 901, on the other hand, the powder can fall into the material distribution tank 300 at a uniform speed during vibration to be conveniently measured, in order to further control the flow rate of the powder, a group of baffles 903 with unequal heights are configured in the conveying shell 901, the flow rate of the powder is controlled by expanding different baffles 903 to control the size of a powder flow channel in the conveying shell 901, for example, all baffles 903 are opened at an initial node, the powder channel is maximally enabled to flow into the material distribution tank 300 rapidly, when the material distribution tank 300 detects that the weight of the powder reaches a designated weight, the baffles 903 are sequentially turned over, the channels of the powder flow are sequentially reduced, the channels of the powder flow are enabled to be enabled to fall into the material distribution tank 300 to be convenient to measure through the material distribution tank 300 when the weight is required to be turned over, and the channels of the powder falls into the material distribution tank 300 through the air cylinder to be controlled by the accurate control requirements of the weight. When the powder reaches the specified weight, the vibration element 902 can be stopped to ensure that the powder does not fall into the material mixing tank 300 any more, but part of the powder still remains in the conveying shell 901, so as to avoid the influence on the accuracy of the proportion of the powder entering the material mixing tank 300 caused by vibration in the running process of the equipment, a valve 500f is also arranged on the discharge port of the vibration feeder 900, and when the weighing reaches the target value, the valve 500f is closed to prevent the powder from continuously falling into the material mixing tank 300.
