Description

Technical Field

[0001] The invention relates to a cloth piece and fiber separation device, belonging to the field of waste textile regeneration processing machinery. Background Art

[0002] With the development of society and the improvement of living standards, textiles are frequently updated, resulting in the generation of a large amount of waste textiles. Waste textiles come from various stages of the textile product life cycle and are often treated in various ways such as incineration and landfill, causing increasingly prominent environmental pollution problems.

[0003] The "China Waste Textile Comprehensive Utilization Development Report 2020-2022" released by the China Circular Economy Association pointed out that the comprehensive utilization of waste textiles is of great significance to saving resources, protecting the environment, and helping to achieve the "dual carbon" goals. It also proposed development goals by 2025 and 2030, including the establishment of a waste textile recycling system and the increase in the output of recycled fibers.

[0004] Therefore, resource recycling has become an indispensable link in the textile closed loop.

[0005] Waste textile recycling generally refers to the recycling of waste materials generated during the production and processing of textile products, which belongs to the recycling of waste textiles before consumption. With the breakthroughs in the comprehensive utilization technology of waste textiles in recent years, the recycling and reuse system of waste textiles has gradually improved.

[0006] Most of the existing recycling processes for waste textiles adopt the non-separation method, which uses mechanical processing to cut, tear, loosen, comb and other processes on waste textiles to process them into recycled fibers or recycled cotton.

[0007] The existing recycled cotton production process is to repeatedly open the waste through more than 6 opening machines to make the waste into fibers again. In this process, the fibers obtained after multiple tearing and opening are short in length and low in strength. And as the number of opening machines increases, the number of openings also increases. As a result, the spinnability of the recycled fiber is poor and cannot meet the use requirements.

[0008] China's patent discloses a utility model patent named "rag fiber separation device for fiber regeneration". This patent uses a cloth slide plate to separate rags and fibers. The principle is that the raw material slows down after passing through the cloth slide plate, and the fibers and rags are separated by positive pressure by taking advantage of the different specific gravity of the fibers and rags, which is convenient for the subsequent fiber combing process and spinning. This patented technology avoids repeated opening of the fiber to damage the physical properties of the fiber. However, this patent still has the following problems:

[0009] 1. The rag fiber separation device for fiber regeneration has a horizontal structure, and the raw material path is set horizontally. It is large in size and occupies a large area, so it is not suitable for installation in a small space;

[0010] 2. The degree of automation and production efficiency are low.

[0011] A Chinese patent discloses an invention patent named "A cloth fiber separation device for recycled cotton production". This patent uses the negative pressure generated by the duct fan to suck the cloth fiber mixture into the separation device, and uses the centrifugal force generated by the volute structure and the different densities of the cloth and the fiber to separate the cloth from the fiber. However, this patent still has the following problems:

[0012] 1. Cloth pieces and fibers are entangled with flexible materials. The compact volute structure makes it difficult to completely separate small cloth pieces and fibers from mixed fiber materials after multiple openings by single air separation. Summary of the invention
