The most basic machinery and equipment required by the textile industry are as follows: blower, carding machine, combing machine, drawing frame, roving frame, spinning frame, groove drum. Textile machinery is all kinds of mechanical equipment needed to process natural fibers or chemical fibers into textiles.
Carding machine is used to process cotton fiber and chemical fiber, which belongs to textile machinery. According to the spinning process, carding is an important process.
The front process of the carding machine is the combined opening and cleaning machine, and the subsequent process is the drawing frame (carding process) or sliver coiler (combing process).
The combing machine refers to the machinery used to realize the combing process in the spinning process. The main function is to exclude short fibers, remove kinks (neps, wool particles, grass clippings, cocoon skin, etc.) in the fibers, make the fibers further straight and parallel, and finally make combed slivers with relatively uniform thickness.
The function of the drawing frame is to improve the internal structure of the sliver, so as to improve the uniformity of its long segments, reduce the unevenness of the weight at the same time, make the fibers in the sliver straight and parallel, reduce the hooks, make the fineness meet the requirements, and make different types or Raw materials of different qualities are mixed evenly to achieve the specified mixing ratio. According to the form of drafting mechanism, the drawing frame is divided into two categories: roller drafting drawing frame and needle carding machine.
According to the form of twisting mechanism, the roving frame is divided into wing spindle roving frame and twisting roving frame. The flyer roving frame continuously applies twist to the sliver by the rotation of the flyer to produce twisted roving. The rubbing roving machine relies on a pair of rubbing leather plates to clamp and twist the yarn sliver, forming false twists with positive and negative twists on the yarn sliver, and producing twistless roving. Flyer roving frames and rubbing roving frames can be divided into first pass, second pass and single pass roving frames.
The feeding forms, roving packages and the number of spindles of the various roving frames are different, but the structure and function of the machines are roughly the same.
Spinning frame, during the spinning process, the semi-finished roving or sliver is drawn, twisted, and wound into a spinning machine for spun yarn. The sliver is combed, the sliver is merged by the needle carding machine, the structure of the sliver is improved by the needle row drafting, and the roving is further twisted and spun into spun yarn on the ring spinning frame, which is the main machine for spinning.
The output and quality of spun yarn is a comprehensive reflection of the pros and cons of each process in the spinning process.
The grooved drum is one of the important winding parts on the grooved drum winder. The yarn tension and winding density are the main basis for measuring the quality of the bobbin during winding, and represent the movement law and the yarn ring when the yarn is wound. The distribution on the bobbin and the shape of the spiral groove on it have a direct impact on the shape of the bobbin.
