Description

Technical Field

[0001] The invention relates to a classification and sorting device for recycling waste textiles. Background Art

[0002] With the improvement of the material and cultural living standards of the people, my country, as a major textile production and exporter, has a strong demand for textile consumption, and the renewal of textiles is also fast. The recycling of waste textiles plays an important role in saving resources and protecting the environment. However, my country is still in the development stage, so the recycling of waste textiles is still in its infancy. The good news is that the recycling of waste textiles is gradually being paid attention to by the government and all walks of life.

[0003] Because there are many types of textiles, the directions and methods of recycling are different due to the differences in color and raw materials. Therefore, the current classification and sorting technology of textiles has become the basic premise for textile recycling. The color, composition and other characteristics of waste textiles determine the choice of reuse methods and the level of reuse added value. The core of waste textile sorting is identification, including manual identification and sorting and mechanical identification and sorting. Manual identification and sorting uses human perception through the five senses to identify and classify, which is inefficient, and some raw materials cannot be identified; mechanical identification and sorting uses near-infrared spectroscopy technology and imaging technology to identify components and colors, which has the advantages of high efficiency, speed and non-destructiveness. The commercial utilization of waste textile recycling can only rely on automatic identification and mechanical identification and sorting.

[0004] my country is a big country in e-commerce, and there are many automatic sorting equipment used in logistics. Generally, the goods are guided out of the sorting path at the appropriate position according to the instructions of automatic identification technology (such as barcode or video recognition). According to the sorting path, there are two major types of automatic sorting systems: linear and circular. According to the sorting actuator, it includes transfer type, pendulum type, sweep arm type, sliding shoe type, bag drop type, flip plate type, vertical cross belt type, etc. Because waste textiles are dusty and unpackaged, the existing logistics sorting equipment is not suitable for direct application in the sorting of waste textiles. At present, there is no mature and reliable waste textile recycling, classification, and sorting equipment. It is not conducive to the efficient and maximum recycling of resources.

[0005] At present, the Fibersort automatic sorting system of Valvan Baling Systems in Belgium uses near-infrared spectroscopy technology to identify the components of waste textiles, and then sends the identified waste textiles to designated collection boxes through a blowing system and a conveyor belt. TOMRA Group has developed an integrated near-infrared scanning sorting system that uses flying light scanning technology and compressed air to efficiently identify and sort hard plastics, films and textiles of different materials. The current application project is located in Sweden. A domestic company has developed a bag-drop sorting system using near-infrared technology. The system was hastily discontinued due to the immaturity of the bag-drop actuator and the lack of market recognition.

[0006] Waste textiles are identified and sorted manually, which is in a bad environment, with high labor costs, low sorting efficiency and large sorting differences. A domestic company has developed a bag-drop sorting system using near-infrared technology. The sorting equipment uses a circular site with a large footprint. The technical function is single. Most of the related waste textile sorting uses near-infrared technology for component sorting, and there is no identification and utilization of weight information, color information and abnormal information containing hard objects. Moreover, since waste textiles are not packaged, scattered, contain many short fibers, and have large weight differences, when the actuator adopts a blowing structure, heavy waste textiles cannot be blown, and the bag-drop structure has problems such as loose sealing, material slipping, uncertain falling time, and easy clamping. At present, there is no mature mechanical equipment for the classification and sorting of waste textiles in China. The existing mature logistics sorting equipment is not suitable for the sorting of waste textiles. Therefore, there is an urgent need for the research and development of sorting equipment and technical upgrading. Summary of the invention
