Do you know the basic situation of the loosening machine?

1. The origin of the opening machine The loosening of fiber raw materials was initially done manually. For example, for wool, the wool was first torn by hand to make it tremble, and then beaten with a stick or relaxed with a bowstring. For cotton, the cotton seeds and fibers were also separated by hand, and then the fibers were relaxed with a bowstring. After the advent of machine spinning in the 18th century, there were many raw material reserves, which required a reduction in the transportation volume of raw materials, and the loose fiber raw materials were bundled and packaged, requiring a mechanized method for loosening and removing impurities from raw materials. Since then, various types of opening and removing machines have emerged in an endless stream. 2. The main function of the opening machine is to loosen and tear materials such as fibers, cotton, and fabrics, so that large pieces of tangled fibers are loosened into small pieces or bundles, and the loosening process is accompanied by mixing and removing impurities. The opening machine is generally composed of a pair of feed rollers or a feed roller and an opening cylinder. Square nails, combing needles, card clothing, and porcupine hands are installed on the opening cylinder. Some working rollers and stripping rollers are installed on the cylinder to further improve the opening effect. Different structures have obvious differences in the effects of tension, mixing and impurity removal. Therefore, different types of tension machines should be used according to the required production lines. You can also choose an opener according to the raw materials to be processed, and supply the opened fibers to the carding machine for processing. 3. Types of openers PP cotton opener, cloth end opener, polyester staple fiber opener, silk fabric opener, airflow opener, three-sawtooth roller fine flax opener, fabric waste opener, vacuum opener, doll cotton opener, etc. 4. Opener The quality identification of fiber raw materials is specifically reflected in the various quality indicators and falling objects of the semi-finished products (fiber rolls or fiber layers) after opening. This includes: ① The type and quantity of impurities and defects in the semi-finished products; ② The structure and uniformity of the semi-finished products ③ The content of short fibers in the semi-finished products; ④ The looseness of the fiber clusters is expressed by the average weight of the fiber clusters (g/block), the unit volume weight (kg/m3) or the terminal velocity of the fiber clusters settling freely in the air; ⑤ The number of weavable fibers contained in the falling objects. In order to further improve the loosening quality of fiber raw materials and improve the quality of yarn, the main development direction of the loosening process is to improve: the form and structure of loosening machine parts. Widely use comb-shaped parts such as needle rollers, combing needle hands or combing needle rollers to increase the looseness of fiber groups and improve the structure and uniformity of semi-finished products; strengthen the pre-opening of fiber raw materials. In the process of opening, use free blows to minimize grip blows; use airflow and other loosening removal methods to avoid fiber damage and impurity crushing, and reduce the resulting yarn defects.
