Color-selecting light source structure of color selector with multi-angle color selecting function

Abstract

The invention belongs to the field of color-selecting light sources of color selectors and more specifically relates to a color selector light source structure capable of illuminating color-selecting materials from a plurality of angles. According to the color-selecting light source structure of a color selector with a multi-angle color selecting function, a color-selecting illuminating light source is arranged inside a sorting box; a slide plate or a slideway of materials is arranged just at the front of the sorting box; LED (light-emitting diode) light sources are fully arranged along the lower end edge of the slide plate or the slideway of the materials, so that the light source can illuminate the rear part of the color-selected materials. According to the technical scheme disclosed by the invention, the color-selecting light source structure of the color selector capable of illuminating the color-separating materials from a plurality of angles guarantees that a shadow does not appear below the materials when color selection is carried out on large particle materials, so that the color-selecting efficiency of the materials is improved.

Description

technical field [0001] The invention belongs to the field of color sorting light sources for color sorters, and more specifically relates to a light source structure for color sorters capable of illuminating color sorting materials from multiple angles. Background technique [0002] Color sorters are widely used in many fields, such as the food industry for color sorting and grading of sesame, peanuts, rice, soybeans and other grains, and some chemical industries such as plastic sheets, plastic granules, salt, etc. can also use color sorting machines for color sorting and grading Sorting or removing impurities. The color sorter uses photoelectric technology to automatically sort out the different-color particles in the granular material according to the difference in the optical characteristics of the material. At present, the photoelectric color sorter independently developed in China has also been widely used. However, most of the existing color sorters use the tradition...

Problems solved by technology

However, most of the existing color sorters use the traditional slide-type color sorting lighting method. The color sorting lighting source is mostly installed in the sorting box, and the light source is irradiated on the surface of the skateboard. When the color sorting is working, the color sorting light source can only shine on the On the surface of color sorting material particles, when color sorting peanuts, broad beans, cashew nuts and other bulky materials, there will be a large shadow under the material. The existence of this shadow will seriously affect the sorting of materials and seriously affect the color. Machine color sorting effect
