The fancy yarn forms of twisting machines are becoming more and more abundant, and the varieties are changing faster and faster, and the functional requirements for flower twisting machines are getting higher and higher. Domestic flower twisting machine manufacturers have been launching new products one after another. Significant progress has been made in quality functions, from simple credit and replication to innovation and design. The structure of twisting machine feeding method is more complicated, including: double drafting system, double hollow ingot system, double coiling system, electrical control system. On the basis of satisfying the general wool type fiber, the double draft feeding system also takes into account the general cotton type fiber. It adopts the structure similar to the wool spinning drafting system, the upper and lower double aprons structure, the diameter of the upper roller is 50mm, the diameter of the lower roller is 38mm, the cleaning pile is used on the front upper roller, and the cleaning pile is used on the front lower roller, usually suitable for spinning fibers 60-190mm, large Fiber lengths of 220mm or more can be spun. Double hollow spindle twisting system The hollow spindle system adopts an independently designed small tilt-pull spindle, the spindle length is 248mm, and the false twist nozzle is a combination of wire hook and inclined nozzle, which is more stable and reliable than the original 420mm spindle. to improve. The upper and lower structure adopts two ordinary dragon belts, which are driven by two frequency conversion machines respectively. The diameter of the friction wheel is reduced by 30% compared with the original, the speed of the spindle can be increased without increasing the speed of the main motor, and the energy consumption is reduced. The lifting/upgrading system of the double winding system is driven by a stepping motor, and the thickness of the fancy yarn varies widely. According to the requirements of spinning different thicknesses, the stepping motor drives the lifting/upgrading system, and the yarn counts of different counts Different lift ranges are required for different lift speeds. When spinning fancy yarns with finer counts and single-pressed yarns, due to the higher twist of the finer-counted yarns, it is easy to produce twisting and knotting, and the fabric is skewed and feels hard. Ring/ring winding.
Both winding forms are non-stop doffing. Using microcomputer control, it can be adjusted arbitrarily to ensure the spinning quality. The electrical part of the electrical control system consists of 6 stepping motors and three variable frequency motors. Since the execution tasks of each motor are different, the movement speed is required to change in various ways with the complex requirements of the computer command, so the requirements for the computer controller are more stringent.
