colour sorter working principle
Selected material from the hopper into the machine through the vibrator device vibration, the selected material along the channel into the observation area of ??the sorting room, passing through the CCD sensor and the background plate, under the illumination of the light source, the CCD from the selected material Of the synthesis of optical signals, the system generates output signals, and amplified to the processing operation of the processing system, the optical signal into electrical signals by the control system to issue instructions to drive the electromagnetic valve jet blowing different color particles to the waste area, a good continuation Down to the best material area, to achieve the purpose of sorting.
Affect the color selection effect of several major factors:
1, camera resolution
2, software algorithms, the ability to distinguish color
3, feeding system
4, nozzle performance
Proper nomenclature for color sorters
1, the net rate of selection: the sample after the actual removal of the color selection of color materials and color selection before the need to remove the ratio of different color materials, the higher the net selection rate, the better the performance of the machine.
2, with a ratio of: color selection to remove the color particles and color removal of heavy weight out of the qualified particles out of ratio, with a smaller ratio, the better the performance of the machine.
3, production: the total weight of materials per hour.
4, the channel: refers to the color sorting machine to complete the removal of the number of different particles action mechanism nozzle number, the same as the number of solenoid valve.
