Color selector illuminating system

Abstract

The invention discloses a color selector illuminating system. The color selector illuminating system comprises light sources, glass, a light source control touch screen and background plates, wherein the glass is used for separating the light sources and the background plates from materials; the light sources are coaxial light sources; an edge filter is arranged on the periphery of each coaxial light source; an electronic thermostat is arranged under the coaxial light sources; a layer of antireflection film is coated to the surface of the glass; and a layer of high-reflective film is coated to the surface of each background plate. The color selector illuminating system disclosed by the invention has the advantages that the semi-annular coaxial light sources are designed, so that the color rendering property and the light reflection strength are improved, and the uniform illuminating can be realized; unwanted radiation is removed, so that the radiated interference is avoided; the light transmittance of the glass and the light reflection rate of the background plates are improved, so that the signal-noise ratio is increased, and high-accuracy sorting is facilitated; the electronic thermostat is favorable for keeping the temperature in the sorting chamber constant, so that the condition that the change of light reflection properties of the materials and the light reflection properties of the background plates due to temperature change is avoided, and the sorting accuracy rate is further increased; and compensators are separately arranged on the background plate mounting seats, so that the vibration and local displacement of the equipment can be absorbed, and the background plates can be kept stable.

Description

Technical field [0001] The invention relates to the field of color sorters, in particular to a color sorter lighting system. Background technique [0002] The color sorter is a device that uses photoelectric technology to automatically sort out heterochromatic particles in granular materials according to the differences in the optical characteristics of materials. Under the action of the light source, it is judged whether the material is defective according to whether the reflective characteristics of the material and the background plate are the same. When a defective product is encountered, the system generates an output signal to drive the solenoid valve to blow out particles of different colors into the waste cavity of the receiving hopper, and the good selected objects continue to fall into the finished product cavity of the receiving hopper. The light source of the traditional color sorter lighting system mostly uses ordinary LED lights, which have the defect of low color ...
