Automatic weighing system and method for solid particle or powder materials

Abstract

The invention relates to an automatic weighing system and method for solid particle or powder materials. The automatic weighing system comprises a sample weighing device, a source sample container, atarget sample container and a robot, and the sample weighing device comprises a sample input end, a sample weighing unit and a sample output end. The sample input end is arranged at one side of the sample weighing unit, and the sample output end is arranged at the other side of the sample weighing unit; the robot is used for conveying the source sample container to the sample input end of the sample weighing device and replacing the source sample container in the sample input end, at the same time, conveying the target sample container to the sample output end of the sample weighing device andreplacing the target sample container in the sample output end, and the sample weighing unit is used for quantitatively pouring the particle or powder materials in the source sample container at thesample input end into the target sample container at the sample output end. Compared with the prior art, the batch weighing of solid particle or powder samples during detection can be achieved, the automatic operation is achieved, and the weighing efficiency is high.

Description

[technical field] [0001] The invention relates to the technical field of automation equipment, in particular to an automatic weighing system and weighing method for solid particles or powder materials. [Background technique] [0002] In the food, chemical, and inspection and testing industries, when testing granular or powder products, samples need to be accurately packaged. In these industries, when a large number of samples and samples of various types need to be packaged and weighed, traditionally, the samples are divided and weighed manually. However, its heavy workload and low efficiency have increasingly failed to meet the needs. [0003] The existing manual operation is realized by a sample divider. Specifically, the solid particles or powdery substances are first put into the sample divider, and then evenly divided into other containers by the sample divider. Although this type of sample divider can ensure the accuracy of sample division, the sample needs to touch ...

Problems solved by technology

Although this type of sample divider can ensure the accuracy of sample division, the sample needs to touch the sample divider during the sample division process. If the sample divider is used to divide other samples, cross-contamination will occur. At this time, the sample divider needs to be cleaned before proceeding. Divide the next sample, which will lead to low efficiency of sample division

[0004] Secondly, when testing the performance of samples in the laboratory, since the original samples used for testing are often small, any contamination of the samples will affect the accuracy of the test results, and the use of traditional sample dividers will not only cause sample loss during transfer, And pollution will be generated during the transfer process

Therefore, existing sample dividers are not suitable for
