Drawframe Machine

Introduction The draw frame in a framework lurk is unavoidable in narrative spinning as parts need to be kept side by side termed as parallelization of fibers in textile technology. This is done as we see that most of the fibers at carding stage be so fast that there is little or no fiber parallelization. Even though modern carding forges grant using the auto leveler thus far there stinker be some unevenness along the parings. These deuce issues will affect the quality of the yarn. The draw frame implement is the become machine which lot improve the yarn quality in the yarn manufacturing process.The tasks outline and multiply argon the objectives of the draw frame machine in order to improve the fiber orientation and shaving uniformity respectively. remotion of hooks and dust also can be carried out by the machine, at a significant amount. Objectives To study the actual path, objectives and drafting body of the draw frame machine. Procedure * Study the important par ts and their proceed of the machine * Observed and draw the material path * Roller drafting system was observed * Compare the differences between modern and received machineDraw frame material path (picture) Tasks of the draw frame * unrivalled of the main tasks of the draw frame is astir(p) the evenness over short, strength and especially, long terms. Card grazings fed to the draw frame have a degree of unevenness that can not be tolerated in practice. multiply is the process of combining two or more slivers usually from carding railway locomotive to deliver a single sliver. In the draw frame 6-8 slivers are combined to give one sliver. During the doubling process it is expected that the non-uniformity is in the card sliver will be even-out and a uniform sliver will emerge. Drafting is a process where the weight per unit distance of the input sliver is reduced. During the drafting process, fiber parallelization also takes place. The drafting and doubling processes are achie ved by passing the slivers through rotating rollers. The fluted bottom rollers are stain rollers while the top rollers are man-made rollers heavily weighted on the bottom rollers by means of springs. The bottom rollers are run at increasing speeds starting from the back rollers to the front rollers. In addition to the improving evenness, doubling also provides a degree of compensation of raw material variation by blending. The result is exploited in particular in the production of blended yarns comprising cotton/synthetic or synthetic/synthetic blends. At the draw frame, metering of individual components can be carried out real simply by selection of the number of slivers enter the machine * stud is steadily becoming a greater problem both in processing and personnel involved. It is therefore significant to remove dust in every possible step in the process.Dust removal can only be carried out where there is fiber/fiber, fiber/ admixture friction. Since dust articles adhere relat ively strongly to the fibers. A high military operation draw frame with a sufficient number of suction take down is a good dust-removing machine. * Sliver formation and coiling is also a important part of the draw frame process using sliver trumpet and calendar roller this functions were done. Differences of drafting systems between modern and conventional draw frame * Modern draw frame machine have helical flute where the conventional machine have horizontal flute. stately modern (horizontal) (helical) * In conventional drafting system 4/4 system is used where in modern drafting system 5/4 system is used. * In the modern machine the flutes are abandoned and in conventional machine flutes are arranged in groovy line. * In the conventional system lever type pressure beef up system is used and in modern system spring debauch system is used. In addition to this the modern draw frame machine have the followings * Single prevention- if for whatever reason a sliver get exhausted o r broken the machine will mechanically stop * Colour light system-indication at which circumstantial presage the problem is in the machine which cause into stop * Red-mechanical problem * Green-sliver tire out * White-power on no run * Blue-over heat * Orange-no can * Automatic can changing- the machine can be programmed to deliver a specific length of sliver on to the two can after which the cans are automatically changes to new cans.
