Abstract

The invention discloses a multi-station high-precision quantitative weighing device which includes material-sending components, a feeding mechanism, a residual material collecting component, a rotating device, a lifting device and a weighing component. The lifting device is mounted on a machine frame base, the upper end of the lifting device is connected with the rotating device, the rotating device is connected with a material-sending platform, the material-sending platform rotates with the rotating device and performs lifting motion with the lifting device, the material-sending platform is provided with a plurality of groups of material-sending components, the feeding mechanism is disposed on one side of the material-sending platform and conveys powder into the material-sending components, the residual material collecting component is disposed below the feeding mechanism, the weighing component is disposed on the other side of the material-sending platform, and the material-sending components are placed above the weighing component or the residual material collecting component after rotating through the rotating device. The multi-station high-precision quantitative weighing device is arranged into multi-station weighing and has functions of automatically and quickly quantitatively weighing the powder, auxiliary time during the weighing by workers and devices is reduced, and the weighing efficiency and precision are improved.

Description

technical field [0001] The invention relates to the field of powder weighing, in particular to a multi-station high-precision weighing and quantifying device. Background technique [0002] In the field of automatic powder weighing and weighing, such as mining machinery, cement, food processing and other industries, belt scales are generally used for weighing and measuring in the prior art, and the weighing level is basically above 1.0kg, even in tons. The accuracy is basically around one thousandth. In laboratories, fine chemicals, military products and other fields, it is generally required to weigh powders within the range of 1-30g, the accuracy is mostly required to be less than ±0.01g, and the error range is mostly required to be within 0.01%-0.3%. At this level of application, there is no automatic weighing and quantitative device on the market. At present, related industries generally use electronic balance manual weighing. This method depends entirely on the operator...
