1. The high-performance servo motor is used to guide the yarn, so that the line speed can reach more than 800 m/min, or even 1800 m/min, which can double the production efficiency and reduce the cost. 2. Using comprehensive intelligent control technology to replace the mechanical structure, the machine performance has reached the international advanced level, and the operation and adjustment are convenient and simple. 3. Adopting intelligent constant tensioner system, active de-burning yarn feeding system and automatic tracking overfeeding system to ensure stable yarn forming. 4. Computerized automatic stop when thread breaks, single spindle length counting device, and all encoders are used to detect and control the speed, so that the yarn production has consistency. 5. All are driven by brushless motors, intelligently and arbitrarily adjustable forming length, trimming angle, controllable soft edge density, to ensure uniform packaging density. The winding process is an indispensable process in the spinning process. With the development of semi-worsted spinning technology, the role of automatic winders in semi-worsted spinning production has been paid more and more attention. In semi-worsted spinning production, more advanced automatic winders are generally used, which are mostly equipped with electronic yarn clearers and air splicers, which have high degree of automation, low failure rate and high quality of winding. The big advantage is variety adaptability. powerful. Moreover, for some special semi-worsted yarn varieties, normal production may not be possible on ordinary winders, but the use of automatic winders can achieve a multiplier effect with half the effort. Technical parameters of the winder: Number of spindles: 48 spindles Spindle pitch 360mm Linear speed 200-1800m/min Tension method: Combination of electronic tension and clamp-grid tension Winding stroke 130mm-260mm Edge angle 0o-60o Rated power 400W The price of the automatic winder adopts a DC brushless motor. When braking, the motor can make the current flow to the main power source and be used as a generator to achieve the purpose of energy saving. The main fan adopts frequency conversion control, and the air volume can be changed according to the needs of the process, thereby avoiding the waste of excess air volume. Due to the joint cycle logic control, the equipment reduces unnecessary actions, which not only saves energy but also reduces wire waste.
