Problems solved by technology

However, the existing sampling methods of spectral detectors mostly use manual single sampling, especially the spectral detectors used for scientific research and teaching, which have not realized automatic sampling and online detection.
At the same time, the existing instruments basically collect the spectral information of a single region for the spectral collection of the sample, which is not comprehensive for obtaining the spectral information of the sample to be tested. To collect the spectral information of multiple regions of a single sample, the sample needs to be converted manually. position and then re-collect spectral information, which will inevitably bring great inconvenience to the collection work

Abstract

The invention discloses an automatic sample feeding apparatus of near-infrared spectral online detection and a control method of the automatic sample feeding apparatus. The automatic sample feeding apparatus comprises an intermittent sample feeding mechanism and a sample rotating mechanism. The intermittent sample feeding mechanism comprises a sample feeding turntable, wherein a plurality of test tube clamps are arranged on the sample feeding turntable, the bottom of the sample feeding turntable is connected with a turntable drive disc, and a first drive mechanism drives the sample feeding turntable and the test tube clamps to rotate. The sample rotating mechanism comprises a cam transmission shaft connected with a second drive mechanism, wherein the cam transmission shaft is provided with a cam by virtue of an overrun clutch, and the other end of the cam transmission shaft is connected with a clamp drive shaft by virtue of a bevel gear pair; the cam is connected with a bearing frame by virtue of a cam roller and a push rod; two positions of the middle part of the clamp drive shaft are respectively installed in one end outside a cam transmission case and in the bearing frame, and the other end of the clamp drive shaft is fixedly connected with a clamp drive disc for driving the test tube clamps to rotate. By adopting the automatic sample feeding apparatus, the automatic sample feeding can be realized, spectral information of a sample at various positions is acquired, and a relatively complete sample spectral acquisition information can be obtained.

Description

technical field [0001] The invention relates to an automatic sampling technology for optical non-destructive detection of agricultural product quality and safety, in particular to an automatic sampling device for near-infrared spectrum on-line detection and a control method thereof. Background technique [0002] In recent years, spectral detection technology has developed rapidly, and its application has also expanded to various fields. However, the existing sampling methods of spectral detectors mostly use manual single sampling, especially the spectral detectors used for scientific research and teaching, which have not realized automatic sampling and online detection. At the same time, the existing instruments basically collect the spectral information of a single region for the spectral collection of the sample, which is not comprehensive for obtaining the spectral information of the sample to be tested. To collect the spectral information of multiple regions of a single ...
