I. Introduction

 

In the process of picking, transporting and processing, cotton will inevitably be mixed with various impurities, such as leaves, branches, sand and so on. These impurities not only affect the quality of cotton, but also may adversely affect subsequent textile processing. Therefore, the effective sorting of impurities in cotton is a key link to ensure the quality of cotton. Although the traditional manual and wet separation methods can remove impurities to a certain extent, the separation rate is low and there are many shortcomings. With the continuous development of X-ray detection technology, its application in cotton impurity sorting has gradually highlighted its advantages.

 

Second, X-ray detection of cotton impurity sorting system overview

 

X-ray detection cotton impurity sorting system is a kind of system which uses X-ray to penetrate cotton image and realizes automatic impurity sorting through image recognition technology. The system is mainly composed of X-ray source, detector, image processing unit and sorting device. During the inspection process, the X-ray source emits X-rays, which penetrate the cotton layer and are received by the detector and converted into a digital signal, which generates an image of the interior of the cotton. By processing and analyzing these images, the image processing unit can identify the impurities in cotton, and control the sorting device to automatically sort out the impurities.

 

Third, X-ray detection of cotton impurity sorting system and manual cotton selection and wet selection method comparison

 

Limitations of manual cotton selection

Manual cotton selection is a traditional impurity sorting method, which mainly relies on the vision and experience of workers to judge and sort the impurities in cotton. However, there are obvious limitations to this approach. First of all, the sorting rate of manual cotton is affected by many factors such as workers' skill level, fatigue degree and working environment, which leads to unstable sorting results. Secondly, the efficiency of manual cotton selection is low and can not meet the needs of large-scale cotton processing. In addition, manual cotton selection for a long time may also cause adverse effects on the health of workers.

Shortcomings of wet selection

Wet separation method is a method of separating impurities from cotton by soaking cotton in water and using the buoyancy of water. Although the wet separation method improves the separation efficiency to a certain extent, there are still some shortcomings. First of all, wet selection may cause cotton to absorb too much water, affecting the quality of cotton and subsequent processing. Secondly, the separation effect of wet separation method is not good for some impurities with similar density to cotton, and the separation rate needs to be improved. Finally, the wet selection method also needs to dry the treated cotton, which increases energy consumption and cost expenditure.

 

Advantages of X-ray detection of cotton impurity sorting system

Compared with manual and wet sorting methods, X-ray detection cotton impurity sorting system has significant advantages. First of all, its sorting rate is high. Because X-rays can penetrate the cotton layer and accurately identify impurities inside the cotton, the system can accurately identify and sort out various impurities, including fine impurities with similar density to the cotton. Secondly, the system operation has a high degree of automation, which can continuously and efficiently carry out impurity sorting, greatly improving the sorting efficiency. In addition, the X-ray detection cotton impurity sorting system also reduces manual intervention, reduces labor costs, and avoids sorting errors caused by worker fatigue or insufficient skill level.

 

Fourth, X-ray detection of cotton impurities sorting system high sorting rate analysis

 

High precision imaging technique

The cotton impurity sorting system uses high-precision X-ray imaging technology to clearly show the structure and impurity distribution inside the cotton. This technology allows the system to accurately identify and locate various impurities, whether large blades or tiny sand particles, which can be effectively identified and sorted out.

 

Advanced image recognition algorithm

The system is equipped with advanced image recognition algorithms that enable accurate analysis of X-ray imaging. Through algorithm optimization and parameter adjustment, the system can identify and classify various impurities more accurately, and further improve the separation rate. In addition, with the continuous development of machine learning and artificial intelligence technology, the recognition ability of the system is still improving, which is expected to further improve the sorting rate.

 

Advantages of automated operation

X-ray detection cotton impurity sorting system adopts automatic operation mode, which reduces the interference of human factors. Through precise robotic arms and transmission devices, the system can achieve fast and accurate picking and sorting of impurities, avoiding sorting errors caused by improper manual operation. At the same time, the automation also greatly improves the sorting efficiency, making the system able to cope with the needs of large-scale cotton processing.

 

V. Conclusion and prospect

 

Through the comparison and analysis of the X-ray detection system of cotton impurity sorting, manual cotton sorting and wet sorting, it can be seen that X-ray detection has significant advantages in cotton impurity sorting. Its high-precision imaging technology, advanced image recognition algorithm and automatic operation make the sorting rate significantly improved. In the future, with the continuous progress of technology and the expansion of application fields, the X-ray detection cotton impurity sorting system is expected to play a greater role in the field of cotton processing, and make greater contributions to improving cotton quality and processing efficiency. At the same time, we should continue to study the optimization and improvement methods of X-ray detection technology to further improve the sorting rate and stability of the system
