Abstract

The utility model belongs to the field of color selector color selecting light sources, and relates to a device for preventing the light reflection of a color selector in the multi-angle lighting. The device adopts the scheme that color selecting lighting sources are mounted inside a sorting box; a sliding plate or a slide track of materials is mounted at the front position of the sorting box; LED light sources are fully arranged at the lower end part of the sliding plate or the slide track of materials along the edge of the sliding plate or the slide track; a layer of polarization thin film is arranged on the surface of each LED light source; polarized light optical filters are arranged on camera lens of cameras. According to the utility model, through the adoption of the technical scheme, color selected materials can be irradiated at multiple angles to guarantee that shadows do not appear below materials when materials with larger particles are subjected to color selecting and guarantee that the light reflection is avoided when the cameras are used for performing color selecting on materials irradiated by hard light from multiple angles, so that the color selecting efficiency of materials is improved.

Description

A kind of anti-color selector multi-angle illumination reflex reflector

Technical field

The utility model belongs to color selector look and selects light source field, and relating in particular a kind of color selector can select material and reflective anti-color selector multi-angle illumination reflex reflector occurs from a plurality of angle illumination looks.

Background technology

Color selector is widely used in a lot of fields, as food service industry, the cereal such as sesame, peanut, rice, soybean are carried out to look and select classification, the classification of tealeaves, some chemical industries are as plastic sheet, plastic grain, salt etc. also can be used color selector and carry out look choosing classification or remove impurity.Color selector is according to the difference of material optical characteristics, utilizes photoelectric technology by the heterochromatic particle automatic sorting in granule materials out.The photoelectric colour sorter of Present Domestic independent research is also widely used.But existing color selector, adopt traditional slide type look to select lighting system, look selects lighting source to be arranged in separatory vessel more, light source irradiates the surface with slide plate, when look selects work, look selects light source can only be irradiated to the surface that look selects material particles, when look selects peanut, broad bean, during the large material of cashew nut equal-volume, can below material, there is larger shade, the existence meeting of this shade causes serious impact to the sorting of material, have a strong impact on color selector look and select effect, for solving this class problem, adopt the lighting source that a plurality of positions or angle are set on color selector more, like this, the illumination that will shine into some angle is too strong, make setting and the camera lens in separatory vessel occur reflective phenomenon, make material over-exposed, have a strong impact on equally color selector look and select efficiency.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of while selecting for color selector look, can be from a plurality of angle illumination materials, and look phase selection machine there will not be reflective anti-color selector multi-angle illumination reflex reflector, to guarantee when look selects the material of larger particles, below material, there will not be shade and there will not be reflectively, improve the efficiency of material look choosing.

For solving the problems of the technologies described above, the utility model provides a kind of anti-color selector multi-angle illumination reflex reflector, color selector includes separatory vessel, the slide plate of material or slideway, look is hanked as camera and camera lens, when mounted, look selects lighting source to be installed on separatory vessel inside, the slide plate of material or slideway are installed on the positive forward position of separatory vessel, the slide plate of material or slideway are vertical direction or vertical direction slightly tilt direction setting and the separatory vessel forward position of certain angle, at the slide plate of material or slide into bottom, along its edge, full LED light source is all set, LED light source outer setting has lampshade, on the lampshade surface of LED light source, one deck polarization film is set, and on the camera lens of camera, be provided with polarised light optical filter, the polarization film that is arranged at LED light source lampshade surface is vertical with the polarised light optical filter being arranged at before camera lens, utilize the principle of polarization light, when Dry Sack is selected, camera there will not be reflective phenomenon.

The utility model changes color selector light source of the prior art, and the modified color selector look that adopts technique scheme to propose selects light-source structure, in the time of effectively realizing look and select, all angles of material all can be irradiated to by light source, have avoided occurring shade etc. and look selects incomplete phenomenon.When color selector look selects, the look being arranged in separatory vessel selects lighting source to shine directly on the material surface on slide plate, and the LED light source that is arranged on slide plate bottom can be by slide plate irradiated to material below, there is shade below when look selects and affect look and select effect in the material of having avoided larger particles.

The anti-color selector multi-angle illumination reflex reflector that technical solutions of the utility model propose, one deck polarization film is set on LED light source, make LED light source only send polarised light, on the camera lens of camera, be provided with polarised light optical filter, can filtering LED lighting source reflective, guaranteed that the normal look of color selector camera selects work.

Adopt the beneficial effect of technique scheme to be: the anti-color selector multi-angle illumination reflex reflector that the technical program proposes, overcome slide type color selector lighting system traditional in prior art, lighting source is all only mounted in separatory vessel, because separatory vessel and slide plate have certain distance, light illumination can only illuminate the front of material, and the bottom of material can not get sufficient illumination, for peanut, broad bean, can above material, there is larger shade in the material that cashew nut equal-volume is large, can cause on the sorting of material the defect of serious impact, the LED light source that makes to be arranged on slide plate bottom can be from a plurality of angular illumination materials, avoid material below to occur shade etc., the operating efficiency and the look that improve the choosing of color selector look select sorting degree, simultaneously, one deck polarization film is set on LED light source, make LED light source only send polarised light, on the camera lens of camera, be provided with polarised light optical filter, can filtering LED lighting source reflective, the normal look that has guaranteed color selector camera selects work, prevent that camera lens from occurring reflective.This modified color selector look selects light-source structure, and simple in structure, easy for installation, usability is powerful.
