Quartz sand color machine adopts advanced devices as a recognition system
With the development of science and technology, the international mainstream color separator have been advanced on the device as a recognition system. Device is a kind of made up of many tiny photoelectric sensor array, it USES high quality camera appropriative high-definition camera, within the scope of each channel flow of material, usually several to dozens of similar sensors to detect individually (regard as structure of compound eye, and the single piece of silicon photocell is monocular structure). In this way, a grain of rice was divided into several parts were observed by different photoelectric unit, tiny disease spot or light yellow rice signals do not mean by other signals, in the case of large flow rate of disease spot rice or wheat as well as the different color impurities can be accurately identified, thus can improve the color machine production capacity and quality of work, and for small granular materials, such as sesame, also can adapt well.
Color separator from detecting the structure can be divided into two kinds of, unidirectional and bidirectional, and from the process can be divided into a selected and two types with a second check. Old color separator with one-way detection, it only from one direction to material, for the diseased spots on the back of particles or material in the overlapping obscured particles cannot be detected by leakage. Thus, in principle it is incomplete. Two-way detection from two directions before and after the observation at the same time, it overcomes the defect of one-way detection, so it is more advanced, more perfect color separator, can greatly increase production at the same time, increased the color stability and reliability of the machine. A color separator for material only once, at the time of material contain more normal grain of rice or wheat, usually users to accumulate a certain number of coloring machine again to choose a color, is laborious and time-consuming, more troublesome. If you want to make a choice for secondary color color choose, that is to reduce production to a certain degree to reduce the waste of good rice or wheat to carry out than, this way the cost is too big, generally don't like to use. Colour separator and take the second check is picked a color after time containing a higher proportion of normal granular material automatically to choose again, its configuration is back, such as the elevator device, equivalent to two machine simultaneously two color to choose. Therefore, with a second check color separator can minimize waste good content of rice and wheat, save a lot of manpower and time, but also conducive to production and color selection accuracy improved.
