The sliver uniformity of the carding machine is assessed by the weight unevenness rate and evenness rate of the sliver. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.
The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. Special equipment for the textile industry on the winder.
As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. The former indicates unevenness of long segments, and the latter indicates unevenness of short segments. Since the clarity and evenness of cotton slack are closely related to unevenness, the evenness and tick rate of raw sliver are often evaluated by visual inspection of the quality of the cotton web.
The main economic factors affecting the sliver unevenness of the carding machine are: (1) carding quality; (2) the degree of uniform development of fiber transfer to Doffer's opinion, (3) the state of mechanical equipment; (4) cloudiness and breakage Holes, magnetic edges. When the carding quality is poor, the fibers are in the state of bundle fiber cells, so that we can not only affect the uniform material mixing and other effects of the research fibers in the working area of Xinjinlong and Geban, but also make the fibers in the doffer needle surface when the fibers are transferred to the doffer. uneven distribution on the top, resulting in uneven dryness. In addition, when the ability of Xinjinlong and flat card clothing to absorb and release fibers is poor, or the ability of doffer needle teeth to grasp and analyze fibers is poor, Fiber Easy King strengthens Xinjinlong and flat card clothing, so that the two The load on the needle surface affects the quality of carding, and also affects the uniformity and stability of the transfer of plant fibers to the doffer, increasing the evenness rate.
The mechanical learning state of the carding machine is not good, such as the gap is not correct, the licker-in, Xinjinlong, Doffer vibration causes the gap to change periodically, and the coiler part is not properly connected through the gear, etc., which will cause another sliver to not be uniform. Cotton net cloud spot is a cluster of fibers of different sizes in the cotton net, such as cloud or fish scale defects. The reasons for the cotton net are: tissue damage and dullness in the layout of the Xinjinlong needle; the gap between the carding parts and the gap between the back cover and the Xinjinlong is too large or the time is different from left to right, the sticky layer of the cotton lap or Poor opening, the cotton board or the cotton roller becomes bright, not straight, and the pressurization system is not good; the size of the bottom of the flower, the sweet-scented osmanthus is brought in from time to time, etc.
The reasons for the holes and broken edges of the cotton net are: large and small leaks at the bottom and the front and lower hoods, and accumulation of impurities on the surface of the fibers; local or both sides of Xinjinlong or Daoyan scratches; holes in the cotton roll, sticky layer, The edges are not flush, and the head is not well connected; too many osmanthus flowers on the machine frame or wall panel flowers are accumulated, etc. There is direct management of cotton net cloud spots, magnetic moistening and broken edges, which will cause unevenness. Others, such as the position of the stripping roller (or chopper), the distance between the doffer and the coiler, the industry draft and the fine wire tension of each component are too large; the raw sliver weight is too light, etc.
Therefore, the internal control of evenness should be based on the above factors, from the aspects of carding, transfer, mechanical design status and operation ability during operation. Generally, the unevenness rate of raw sliver should be controlled within the range of 14-18.%.
