Most of the existing feeding mechanisms utilize screws for feeding, however, the flowability of many powder materials is poor, and the feeding interruption caused by the arching of the materials can often occur, so that a corresponding auxiliary device needs to be installed in powder feeding equipment to damage the formed material arch, so that the screws can normally feed the powder. For example, the screw type powder quantitative conveying equipment which is disclosed in the Chinese patent network and can be weighed, has the patent number of 202020696071.0 and the publication number of 2021.01.12, and is characterized in that: the device comprises a device main body, wherein a storage mechanism, a conveying mechanism and a back flushing mechanism are arranged on the device main body, the storage mechanism is arranged in the device main body by adopting an assembly frame and extends to the upper end of the device main body, a bearing plate is arranged at the bottom of the assembly frame, and a weighing sensor corresponding to the bearing plate is arranged on the bottom surface in the device main body; the conveying mechanism comprises a conveying motor, a feeding pipe, a conveying screw rod and a dust discharging pipe, an opening is formed in the upper end of the feeding pipe, the opening is hermetically connected with an opening in the lower end of the storage mechanism, the conveying screw rod is arranged in the feeding pipe, the conveying motor is located at one end of the feeding pipe and connected with the conveying screw rod, and the other end of the feeding pipe is connected with the dust discharging pipe; the back flushing mechanism comprises an oil-water separator, an electromagnetic valve and a back flushing component, the oil-water separator and the electromagnetic valve are installed on the side surface of the equipment main body, the back flushing component is installed at the joint of the storage mechanism and the feeding pipe, and the oil-water separator, the electromagnetic valve and the back flushing component are sequentially connected through hoses. A plurality of square holes or round holes can be reserved in the powder feeding equipment in a common arch breaking mode, and when materials are arched and blocked, steel bars are inserted into the equipment and poked up and down to trap the materials. Although this method is simple, the mechanization degree is low, and the labor intensity is high. The mechanical arch breaking mode can be realized by adding a stirring device in the storage bin, but the size of the equipment is increased greatly and the cost is increased greatly due to the fact that an additional speed reducer is required to be added due to the addition of the stirring device. Meanwhile, in the existing mode of breaking the arch by vibration, the lower part of the powder becomes dense and hard continuously due to continuous vibration, so that the formed arch is harder to break than the arch at the initial stage, the screw teeth of the screw rod are in a state without powder materials for a long time, and the phenomenon of not discharging powder is easier to occur.
