The fluffing machine is a modern machine used to process the original tight cotton balls to make them soft and loose, which is convenient for stuffing toys, making cotton clothes, etc. The emergence of this machine has greatly improved the processing efficiency and quality of cotton. The fluffing machine is mainly composed of a body, a conveying system, a processing system and a control system. Its working principle is to send the original cotton into the processing system through the conveying system. In the processing system, the cotton is first pre-treated, such as removing impurities and ties, and then a series of friction, impact and vibration methods are used to gradually tear the cotton balls apart and loosen them. Compared with traditional manual opening, the fluffing machine has many advantages. First, it has high working efficiency and can process large quantities of cotton in a short time; secondly, due to the mechanized processing, manual operation is reduced, labor efficiency is improved, and labor costs are reduced; in addition, machine processing can tear the cotton more evenly, making it looser, and improving the filling performance and warmth retention effect of cotton. The fluffing machine plays an important role in modern cotton processing. Its appearance not only improves production efficiency and reduces costs, but also promotes the development of the cotton industry. With the advancement of science and technology and the continuous growth of market demand, the cotton fluffing machine will continue to be improved and innovated to better meet people's demand for cotton products.
