How to identify the quality of the flowering machine?

How to identify the excellent quality of the flower opening machine? It is specifically reflected in the various quality indicators and falling objects after the semi-finished product (fiber roll or fiber layer) is loosened. This includes: A. The type and quantity of impurities and defects in the semi-finished product; B. The structure and uniformity of the semi-finished product; C. The content of short fibers in the semi-finished product; D. The opening degree of the fiber block is expressed by the average weight of the fiber block (g/block), the unit volume weight (kg/m3) or the terminal velocity of the fiber block settling freely in the air; E. The amount of spinnable fiber contained in the falling objects. In order to further improve the opening quality of fiber raw materials and improve the quality of yarn, the main development direction of the opening technology is to improve the shape and structure of the opening machine parts, widely use the carding machine parts such as the licker-in roller, carding beater or carding roller, improve the opening degree of the fiber block, improve the structure and uniformity of the semi-finished product; strengthen the pre-loosening of the fiber raw material. In the loosening process, use free hammering as much as possible and use less hammering; use airflow and other methods to loosen impurities to avoid fiber damage and impurity crushing, and reduce yarn defects. So the above is all the content shared by our flowering machine manufacturer. I hope you can use it as a reference!
