A device for processing and recycling non-woven fabric scraps

Abstract

The invention discloses a device for treating and recycling non-woven fabric leftovers, which comprises a crushing unit, a cleaning and drying unit, and an opening and carding unit that are arranged inclined to the right and in sequence from top to bottom. The scrapping unit includes a shell , the inner walls on both sides of the housing are rotatably connected with three first drive shafts, the same ends of the three first drive shafts pass through the housing and are jointly connected with the first drive unit, and the three first drive shafts located in the housing A plurality of longitudinal cutting knives are equidistantly and fixedly sleeved on a drive shaft, and the plurality of longitudinal cutting knives in the middle and the plurality of longitudinal cutting knives in the two sides are alternately distributed. The advantage is that the crushed material unit, the cleaning and drying unit, and the opening and carding unit are sequentially arranged on the right side below it, and the cleaning and drying barrel in the cleaning and drying unit is used as the hub connecting the crushed material unit and the opening and carding unit. The treatment of leftovers is standardized and quick, and the treatment and recycling of leftovers are improved.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a non-woven fabric leftover processing and recycling device. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. [0003] In the process of producing non-woven fabrics, a large amount of leftovers are produced. In order to reduce the waste of resources, they are usually treated and recycled. Since dust and impurities are...

AI Technical Summary

Problems solved by technology

Since dust and impurities are adhered to the leftover material, it needs to be cleaned. After cleaning, the internal moisture needs to be dried to avoid being entangled on the outer surface of the opening roller during opening and carding, but the above-mentioned devices usually exist independently. , which requires frequent transportation to different processing devices, resulting in low recycling efficiency of leftovers
