Color Sorter Machine Working Principle

　　The color sorter is a device that uses photoelectric technology to automatically sort out the heterochromatic particles in granular materials based on the color differences of the materials. It is widely used in many fields and is widely used in rice, cereals, nuts, industrial and other industries.

　　It is especially suitable for rice, tea, sesame, beans, melon seeds, peanuts, cottonseed, wolfberry, pepper, seeds, dried shrimps, etc. The effect of sorting impurities and special materials such as raisins, traditional Chinese medicine, glass, plastics, cinders, ores, and special materials is very remarkable and has reached the international leading level.

　　How does the color sorter work

　　First, connect the power supply, turn on the tablet, touch the touch screen to start color selection; then pour the material to be selected for color into the vibrating feeding hopper, and use the high-frequency vibration of the feeder to shake the material and drop it into the material distribution slot; when the material falls into the dividing When selecting a box, two multi-megapixel cameras at the front and rear will comprehensively take high-frequency photos of each material, so as not to miss any blind spots.

　　The pictures will be compared with qualified materials through spectral analysis, and it will be found that materials that are inconsistent with qualified products, have different colors, and the air valve will Unqualified materials are blown into the overflow outlet, and qualified materials fall into the qualified material outlet along the set route.

　　Color sorter structure and composition

　　The main components of the color sorter are feed hopper, vibrating feeder, chute, light source, background plate, CCD lens, discharge hopper, nozzle, air compressor, air storage tank, and filter.

　　1.Feeding system

　　It consists of a hopper, a vibrating feeder and a chute. The raw materials enter the vibrating feeder from the feeding hopper, and are automatically arranged into a series of continuous streamlines through the vibration and guiding mechanism, and after being accelerated by the chute, they drop to the detection area at a uniform speed. To ensure that the materials are clearly present in the sorting cabinet. In addition to the function of providing raw materials, the feeding system also controls the production capacity of the color sorter. Sorting per unit time can be realized.

　　2.Photoelectric system

　　The photoelectric system is the core part of the color sorter, which is mainly composed of LED light source, background board, CCD lens and related auxiliary equipment. The light source provides stable and uniform illumination for the tested material and the background board. The CCD lens converts the reflected light of the tested material into electrical signals in the detection area. The background board provides a reference signal for the electronic control system.

　　3.Sorting system

　　The sorting system consists of sorting cabinets, nozzles, air supply and other accessories. Experiments have proved that the nozzle spacing and the number of nozzles are one of the key factors that affect the accuracy of the color sorter.

　　4.Cleaning system

　　The cleaning system is composed of cylinders, glass cleaning brushes and other components. Because some items contain dust and other impurities, they may stick to the glass during the color classification process. Once dust and impurities adhere to the car window glass, the photoelectric system may cause interlocking problems such as false detection, thereby affecting the color selection accuracy and carry-over rate.

　　5.Operating system

　　The large-screen wide-angle touch screen is used to preset a variety of color selection modes for customers. And establish a friendly man-machine interface, which can be adjusted conveniently and quickly according to the specific conditions of the material.

　　The significance of color sorters

　　Compared with manual sorting, it saves labor, time, high efficiency and low processing costs. Improve the quality and social and economic benefits of the selected products.

　　Different types of color sorters

　　Although manufacturers produce different types of color sorters, most belong to the following three main types:

　　1.Chute color sorters

　　The product chutes of chute sorters are equipped with rows of optical sensors that can operate simultaneously to ensure comprehensive and accurate detection. These machines can quickly sort large quantities of materials and are ideal for high-capacity production lines.

　　2.Belt color sorters

　　This type of sorter uses a conveyor belt to transport materials through a single optical sensor. Because the objects do not move much, they are not easily damaged, so many companies use this type of sorter to sort fragile items.

　　3.Optical color sorters

　　Optical color sorting uses lasers or cameras to automatically sort bulk products. This non-destructive machine can identify the structure, shape, defect size and chemical composition of the product with a detection rate of 100%.

　　WESORT color sorters have higher quality color sorting products, and the products have a great advantage in peer competition, which helps to enhance the brand and reputation. Help customers solve quality problems and help customers grow bigger and stronger.
