Abstract
The invention relates to the technical field of color sorting, and in particular discloses a color sorter imaging background device. The device comprises an euphotic drum and a dust removal brush, wherein two ends of the euphotic drum are arranged on a rack, bristle or a felt of the dust removal brush is attached to the outer drum surface of the euphotic drum along the length direction of the euphotic drum, and the euphotic drum and the dust removal brush rotate relatively in the circumferential direction. The euphotic drum can be directly used as an imaging background of a material to be sorted, so that a camera can accurately acquire color signals of the material; compared with the situation that the dust removal brush brushes a plate-like imaging background back and forth in the prior art, the device has the advantages that through circumferential relative rotation of the euphotic drum and the dust removal brush, the felt of the dust removal brush can quickly clear foreign matters such as dust, chippings and hair attaching to the outer circumferential surface of the euphotic drum, the dust is removed conveniently, the interference on the color sorting operation caused by the dust removal process is greatly alleviated, and the working efficiency of a color sorter is effectively improved.
Description
Technical field
The present invention relates to plant equipment field, particularly a kind of imaging background device of color selector.
Background technology
Color selector is the difference that a kind of basis is treated the optical characteristics of sorting material, utilizes photoelectric technology by the heterochromatic particle sorting for the treatment of sorting material equipment out, and it is widely used in the manufacture fields such as rice, coarse cereals, seed, plastics and ore.During specific works, generally, between the flat imaging background of imaging background device and material path, a colourless light transmission glass plate is set, with the dust that prevents from being mingled with in material, chip, the foreign matters such as hair are attached to the detection that affects imaging system on single color plate, thereby reduce look and select quality, so-called single color plate is namely convenient to the background color object of material imaging to be selected during the color of collected by camera material to be selected, light by light projection on single color plate is adjusted to consistent with the non-defective unit light of material to be selected, so according to the optical characteristics of material to be selected, can be convenient to distinguish and impurities removing.The defect that above-mentioned prior art exists is: described colourless light transmission glass plate needs the dust cleaning brush of deashing device regularly to clean dust, but dust cleaning brush is all generally that backwash is moving on light transmission glass plate in deashing process, so naturally, cause camera in color selector to be difficult to accurately gather the color signal of material, therefore dust cleaning brush camera when cleaning transparency glass plate generally all needs to stop IMAQ, has reduced so undoubtedly the operating efficiency of color selector.
Summary of the invention
The object of this invention is to provide a kind of imaging background device that facilitates deashing, effectively improves color selector operating efficiency.
For achieving the above object, the technical solution used in the present invention is: a kind of color selector imaging background device, it is characterized in that: comprise printing opacity roller and dust cleaning brush, the two ends of printing opacity roller are arranged in frame, the bristle of dust cleaning brush or brush felt are attached on the urceolus face of printing opacity roller along the tube length direction of printing opacity roller, and printing opacity roller and dust cleaning brush formation circumferentially relatively rotate.
The beneficial effect that technique scheme produces is: described printing opacity roller can be directly as the imaging background of material to be selected, can guarantee that like this camera can accurately gather the color signal of material, in tabular imaging background, coming backwash to move with the dust cleaning brush of prior art compares, the present invention is by the work that circumferentially relatively rotates between printing opacity roller and dust cleaning brush, make the brush felt of dust cleaning brush can dispose fast the dust on the outer peripheral face that is attached to printing opacity roller, chip, the foreign matters such as hair, deashing is convenient, and having reduced widely deashing process checks colors and selects the interference of work, effectively improve the operating efficiency of color selector.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present invention;
Fig. 2, the 3rd, the structural representation of two kinds of embodiment of the present invention;
Fig. 4 be the A-A of Fig. 2 to flute profile aluminium the schematic diagram that coordinates with tabular primary colours background.
The specific embodiment
A kind of color selector imaging background device, as Figure 1-3, it comprises printing opacity roller 20 and dust cleaning brush 30, the two ends of printing opacity roller 20 are arranged in frame 10, the bristle of dust cleaning brush 30 or brush felt 31 are attached on the urceolus face of printing opacity roller 20 along the tube length direction of printing opacity roller 20, and printing opacity roller 20 and dust cleaning brush 30 formations circumferentially relatively rotate.During actual use, described printing opacity roller 20 can be directly as the imaging background of material to be selected, can guarantee that like this camera of color selector can accurately gather the color signal of material, and then carry out the sorting work of material to be selected, in tabular imaging background, coming backwash to move with the dust cleaning brush 30 of prior art compares, the present invention passes through the printing opacity roller 20 of tubular as imaging background, while occurring circumferentially to relatively rotate between printing opacity roller 20 and dust cleaning brush 30 like this, the brush felt 31 of dust cleaning brush 30 can be disposed the dust on the outer peripheral face that is attached to printing opacity roller 20 fast, chip, the foreign matters such as hair, deashing is convenient, and having reduced widely deashing process checks colors and selects the interference of work, the present invention preferably two ends of described printing opacity roller 20 rotates and is arranged in frame 10 via bearing, the brush felt 31 of dust cleaning brush 30 is fixed in frame 10, like this position of dust cleaning brush 30 is directly located, and just drive printing opacity roller 20 to occur circumferentially to rotate along its tube length by actuating unit, so color selector can be normal when carrying out cleaning works for dust cleaning brush 30, carry out constantly look and select separation of material, improve widely the operating efficiency of color selector.
As further preferred version: described printing opacity roller 20 is hollow tubular, the two ends of printing opacity roller 20 are provided with end cap, between described end cap and frame 10, bearing 40 is set, printing opacity roller 20 arranges end cap for hollow tubular and its two ends, can avoid like this external impurities to enter the color unicity of printing opacity roller 20 internal influence printing opacity rollers 20, layout by end cap and bearing 40 not only makes printing opacity roller 20 be supported by frame 10, can guarantee that again printing opacity roller 20 circumferentially rotates reliably simultaneously.
