Problems solved by technology
[0003] At present, there are certain deficiencies in the near-infrared detection and sorting production lines of fruits at home and abroad. The unreasonable design will easily lead to the inability to fully collect the fruit spectral information, and there will also be problems with stray light, which reduces the operability of the instrument; It will affect the regularity of the target spectrum and reduce the sorting accuracy of the sorting system

Embodiment Construction
[0018] The present invention will be described in detail below with reference to the drawings in the embodiments of the present invention.
[0019] like figure 1 and figure 2 As shown, a stray light control device for a fruit internal sugar acidity spectrum sorting production line disclosed by the present invention includes a transmission chain, a liftable fruit tray 1, a fruit tray support rod 6, an optical fiber probe 5, a light shielding shell 7, a light source 2 and a fruit tray that can be moved The arch support plate 4 whose position is continuously promoted. The liftable fruit plate 1 is provided with a strip-shaped hole, and adopts a long groove design to ensure that the fruit plate support rod 6 can move in a certain range in the vertical direction relative to the liftable fruit plate 1, so as to realize the lifting function of the fruit plate. like Figure 4~6 Shown is the arched support plate 4 of the core device of the present invention, the upper surface of wh...

The invention provides a stray light control device for a fruit internal sugar acidity spectrum sorting production line, which includes a liftable fruit tray and an arched support plate that can continuously lift the position of the fruit tray. According to this, the stray light control method that the detection section conveying line moves along the arc and the position of the fruit plate is continuously raised is realized. An arched support plate that matches the fruit cup is added to the detection section conveying line, and the stray light control is realized through the arched support plate. In order to reduce the impact of stray light on the detection system; without modifying the production line, the dynamic detection and sorting accuracy of the internal quality of the fruit is improved.
Description
technical field [0001] The invention relates to a stray light control device for a fruit internal sugar acidity spectrum sorting production line, and belongs to the technical field of online nondestructive detection of agricultural and forestry fruits. Background technique [0002] With the continuous improvement of people's living standards, consumers not only pay attention to external qualities such as size, color and shape, but also pay more attention to internal qualities such as taste, sugar content and acidity when purchasing fruits. At present, the sorting of foreign fruits after picking has begun to develop from external quality inspection to internal and external quality inspection. Near-infrared spectroscopy diagnostic technology is a new technology that can detect the internal quality of fruits without destroying the fruits. The United States, Israel, Japan, New Zealand, Belgium and other countries have put this technology into the post-harvest processing of agric...
