The color sorting machine, as its name implies, is a machine that sorts materials according to their colors. Its appearance has liberated labor, and the era of machines replacing manual color sorting has come. With the development of science and technology, the application range of color sorters is gradually expanding. Next, the editor of Xianji.com will introduce the technical indicators, overview, classification, work flow, application scope and maintenance of the color sorter.


Technical indicators of color sorter


1. Processing capacity


The processing capacity is the number of materials that can be processed per hour. The main factors affecting the processing capacity per unit time are the movement speed of the servo system, the highest speed of the conveyor belt and the purity of the raw materials. The high speed of the servo system can quickly send the actuator to the corresponding position of the impurity, which can also increase the speed of the conveyor belt and increase the processing capacity. On the contrary, it is necessary to reduce the speed of the conveyor belt. The throughput per unit time is directly proportional to the movement speed of the conveyor belt. The faster the conveyor belt speed, the greater the output. The throughput per unit time is also related to the proportion of impurities contained in the raw materials. If there are few impurities, the greater the interval between the two impurities, the longer the response time left for the servo system, and the speed of the conveyor belt can be increased. At the same time, the amount of processing per unit time is closely related to the required selection accuracy.


2. Color selection accuracy


Color sorting accuracy refers to the percentage of the number of impurities selected from the raw materials to the total amount of impurities contained. The accuracy of color sorting is mainly related to the speed of the conveyor belt and the purity of the raw materials. The slower the speed of the conveyor belt, the longer the time between adjacent impurities. The servo system has enough time to remove impurities and improve the accuracy of color sorting. Similarly, the higher the initial purity of the raw materials, the less the amount of impurities, and the higher the color selection accuracy. At the same time, the color selection accuracy is also limited by the design of the servo system itself. When there are more than two impurities in the same frame of image, only one impurity can be removed, and the color selection accuracy is reduced. The multiple selection structure is better than the single selection structure.


3. Bring out ratio


The take-out ratio refers to the ratio of the quantity of impurities in the waste material selected by the color sorter to the quantity of normal materials. The level of the take-out ratio can be adjusted, and the adjustment of the take-out ratio is mainly achieved by adjusting the power-on time of the actuator. If the take-out ratio is set too high, it will affect the two indicators of selection rate and processing capacity; if it is set too low, the selected waste contains too much normal materials, which will cause waste; if it is reprocessed, it needs to be invested A certain amount of manpower and material resources will cause a lot of trouble and economic losses.

Overview of color sorter


Color sorter refers to equipment that uses photoelectric detection technology to automatically sort out heterochromatic particles in granular materials according to the differences in the optical characteristics of materials. It has a wide range of applications in food, food, pigment chemical industries and other industries, and it is difficult to sort The sorting effect of recycled plastic chips, plastic pellets, corn, various beans, minerals, peppers, garlic, melon seeds, raisins, seeds, Chinese medicine, sea rice, shrimp skins, cloves, and special materials are very significant.


Classification of color sorters


1. Classified by technology: traditional photoelectric color sorter, CCD technology color sorter, infrared technology color sorter, X-ray color sorter. 


2. Divided by light source: fluorescent tube light source color sorter, LED light source color sorter, microwave light source color sorter, X-ray color sorter.


3. According to the frame: waterfall type, crawler type


4. Divided by material: rice color sorter, miscellaneous grains color sorter, tea color sorter, etc.

Work flow of color sorter


1. The material enters the machine from the hopper at the top, and the selected material falls along the material supply distribution trough through the vibration of the material supply device (vibrator).


2. The material passes through the upper end of the rice channel, and accelerates down the rice channel into the sorting box.


3. After entering the sorting box, from the image processing sensor CCD


Passing through with the background device, under the action of the light source, the CCD receives the synthesized light signal from the selected material, so that the system generates an output signal, which is amplified and processed and then transmitted to FPGA+ARM


The arithmetic processing system, and then the control system sends instructions to drive the injection solenoid valve to act, and the particles of different colors are blown into the waste cavity of the discharge hopper to flow away.


4. Good selected materials continue to fall into the finished product cavity of the receiving hopper and flow out, so that the selected materials can achieve the purpose of selection.


Application range of color sorter


1. Agricultural industry 


The appearance of the color sorter was first applied to the agricultural industry. It can also be said that the color sorter was born for the agricultural industry. The main color sorting materials include: rice, grains, tea, beans, nuts, seeds, medicinal materials, seafood, etc., respectively. There are rice color sorters, miscellaneous grains color sorters, and tea color sorters. Multi-purpose machine, soybean color sorter, etc.


2. Industrial 


The sorting and recycling of garbage is becoming more and more popular. Many businesses have found business opportunities from garbage and made enough wealth. There are even those that specially import overseas garbage to turn waste into treasure. Therefore, industrial color sorting machines have come into being. Many products such as raw materials, plastics, minerals, etc. are specially screened by color sorters.


3. Handicraft market


More and more businesses find that as long as there are products with different colors, they can be screened out by color sorters, such as Buddhist beads, jewelry, etc., so in the handicraft market, we can also find color sorters.


4. Flowers


The flower sorting machine sounds amazing, but it can also be screened. The petals are distinct in color, and the color sorting machine can indeed sort them out well.


Maintenance of color sorter


1. During the start-up period, water should be drained every two hours on average.


2. When the color sorter is working, always pay attention to the operation of the equipment and the effect of color sorting. If abnormal noise is heard or the actual color sorting effect is not good during the period, it should be shut down immediately for inspection.


3. After shutting down, the finishing work must be done well, and the dust on the sliding glass, the hopper and the sorting box glass must be removed to prevent the machine from clogging and rusting.


4. The cleaning brush should be checked regularly to see if it is in place. The camera lens and glass should be kept clean at all times.


5. The filter element of the filter should be cleaned regularly to prevent the filter element from clogging. 


6. Observe the brightness of the lamp to see if it is normal, and prepare for replacement in time.


The color sorter is expensive, and maintenance must be paid at all times to reduce unnecessary losses. I believe that by paying attention to the above six details during maintenance, the service life of the color sorter will be greatly increased.


The above are the technical indicators, overview, classification, work flow, application scope and maintenance of the color sorter introduced by the editor of Xianji.com. The color sorter is a machine with intelligent features. The appearance of the color sorter greatly improves the efficiency of people's selection. It can automatically select materials according to different colors. This is a product of the intelligent era.
