Problems solved by technology

Quantitative weighing by volumetric method is mainly used for quantitative weighing of liquids. The weighing of powdery solids by volumetric method is affected by many factors such as the powder itself and the external state, and it is difficult to complete the high-precision weighing operation of powdery solids. In addition, volumetric weighing is Quantitative weighing operation cannot be applied to the weighing operation of variable quantity, it is difficult to debug, and the control method is single
[0003] Therefore, the current existing technology for weighing solid fine powder affects the weighing accuracy and efficiency, and also has certain limitations for variable operation weighing

Abstract

The invention relates to the technical field of automatic metering and specifically relates to an automatic microscale throttling powder weighing device and weighing method. The device includes a device body and a material holding mechanism and a weighing mechanism arranged on the device body. The upper part of the material holding mechanism is provided with a lift mechanism and a stirring mechanism whose height adjustment is performed by the lift mechanism. The lower part of the material holding mechanism is provided with a hopper transfer mechanism. The material holding mechanism includes a material holding bin and a material collecting ring, a material adding hopper arranged on the upper part of the material accommodating bin and a throttling device arranged in the bottom of the material accommodating bin. The throttling device is provided with a throttling hole. The hopper transfer mechanism includes a transfer hopper. The weighing mechanism includes a weighing support and an electronic scale. The weighing support is connected with the transfer hopper and the electronic scale. The electronic scale realizes powder weighing through weighing weight change of the transfer hopper. The scheme provided by the invention has technical features of high weighing automation level, high weighing efficiency and good weighing accuracy for microscale weighing of power-shaped solid.

Description

Technical field [0001] The invention belongs to the technical field of automatic measurement, and specifically relates to a powder weighing device capable of realizing automatic micro-throttling control and a weighing method using the weighing device for weighing. Background technique [0002] At present, the domestic weighing of fine powdery solids is mainly through the method of balance-feeding weighing and the volumetric method. Among them, the balance replenishing weighing accuracy is high, but it takes a long time to stabilize the balance during the weighing process. The weighing speed is slow. Even a fast-responding electronic balance will have a certain degree of volatility, which affects the accuracy of the final weighing result. In the process of supplementary weighing, once there is an overweight situation, it can only be re-weighed, which greatly reduces the weighing efficiency. Volumetric quantitative weighing is mainly used for liquid quantitative weighing. The volu...
