Differential supplementing device for metal powder bagging

Abstract

The invention belongs to the technical field of metal powder production and particularly relates to a differential supplementing device for metal powder bagging. The differential supplementing devicecomprises a positioning transferring device, a filling mechanism, a supplementing device body and a control device. The positioning transferring device comprises a plurality of positioning jigs and adriving electric cylinder. The filling mechanism comprises a first material falling hopper, a solenoid valve and a first shaking mechanism. The supplementing device body comprises a second material falling hopper, a limiting assembly and a second shaking mechanism. The second shaking mechanism and the middle section of the second material falling hopper are hinged. The packaging bag filling rate is increased, the packaging bag overflow rate is decreased, the semi-automatic powder accurate packaging progress is achieved, a packaging bag is charged continuously, powder falling precision is improved, and the packaging efficiency is improved.

Problems solved by technology

[0002] The existing powder packaging method is to use the weighing packaging method, the electronic scale is used to accumulate and calculate the powder-like materials weighed within a certain period of time, and the electronic scale is used to accumulate and calculate the powder-like materials weighed within a certain period of time. After the preset measurement value is reached, the weighing procedure is completed, which is suitable for the packaging of most powder materials with constant density. This method of weighing and measuring is not suitable for accurate measurement and packaging of powder materials with variable density. , if the above-mentioned weight measurement method is used for the packaging measurement, there will be the following problems: either the packaging bag is not full, or it is overflowing but does not reach the preset weight

[0003] In order to solve the above problems, CN201310627668.4 discloses a powder packaging metering device and method, which includes a vertical cylindrical metering container, the upper port of the metering container is connected to the ash hopper for feeding, and the lower end of the metering container is connected to the packaging The discharge port of the bag; the metering container is provided with a powder feed valve and a powder discharge valve in sequence from top to bottom, and the volume of the metering container between the powder feed valve and the powder discharge valve is equal to The volume of the packaging bag is matched. There is a level gauge above the powder feed valve, and a metering container with a preset volume is used to achieve a constant volume metering and packaging method, which is different from the weight metering and packaging method, especially suitable for frequent bulk density. The measurement and packaging of fluctuating powder materials ensures a high filling rate of the packaging bag in the material packaging and a clean environment during the packaging process. Combined with the matching powder packaging measurement method, compared with the existing weighing measurement, the filling rate of the packaging bag is improved. , reduce the overflow rate of the packaging bag, and realize the accurate measurement and packaging process of variable bulk density powder materials, but only one packaging bag can be fed at a time, and the packaging bag can be continuously fed, and the accuracy of powder blanking is not stable. high
