Optical screening machine is a kind of equipment that uses optical principle to realize material sorting. Its working principle is mainly based on the different reflection, transmission and absorption characteristics of the material under the irradiation of light, so as to achieve the purpose of sorting.

In the optical screening machine, the material is first evenly distributed on the conveyor belt and then irradiated through the light source. Through the irradiation of the light source, the material will produce different reflectance and transmittance, and different materials will have different reactions to the light. The reflected or transmitted signal is detected by an optical sensor and then analyzed and identified by an electronic control system.

According to the characteristics and needs of the material, different parameters can be set to adjust the working mode of the optical screening machine, such as light intensity, irradiation Angle, sensor sensitivity and so on. By adjusting these parameters, the sorting and screening of different materials can be realized, and the accuracy and efficiency of materials can be improved.

The working principle of the optical screening machine is based on the application of optical sensing technology, through the analysis and identification of the optical characteristics of the material, to achieve the intelligent sorting of the material. This kind of sorting method has the characteristics of high efficiency, precision and automation, and can be applied to a variety of fields, such as food, medicine, industry, etc., which provides important technical support for the production process.

In general, the working principle of the optical screening machine is to use the optical principle to achieve the sorting and screening of materials, through the light exposure and sensor detection, to achieve the automatic identification and sorting of materials, improve production efficiency and product quality. With the continuous development of science and technology, optical screening machines will be applied in more fields, providing more possibilities for production.
