The carding machine is a device that finely combs the small rollers into combed sliver. 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.
During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame.
There are single-sided and double-cotton carding machines, each with 6 or 8 versions. my country's self-made A201C carding machine is a single business type. Carding Machine Process The process design process of the A201C carding machine is shown in Figure 6-3.
The small roll 1 is placed on the receiving roller 2, and the receiving roller wants to rotate. Each time the cotton lap is withdrawn, it has a certain length of time. It is guided by the guide plate 3 to be a pair of cotton rollers 4, and the cotton feeding roller is also corresponding. Periodically rotate intermittently, and each time a blunt mouth composed of upper and lower deck boards 5 and 6 is formed with a certain length of cotton feeding. When the jaws are closed, the pliers of the upper and lower decking boards can effectively spread the locust layer, and the brocade layer is suspended outside the jaws. The decking boards can swing back and forth periodically. As the jaws are closed after dinner, the comb surface of the needle row on Xihualin 7 also reaches the bottom of the jaws, and the German needles on the needle m gradually penetrate into the fiber bundle, thoroughly comb the head of the fiber bundle, so that the fibers are straight and parallel, Comb out fixed short fibers and grain defects.
In the late stage of Xinjinlong combing, the pole begins to swing forward, and in the middle of the front swing of the nipper, the upper splint gradually opens, and the combing must be straightened from its own angle. At the same time, the separation roller 8 and the separation skin are 7, but the last cycle of the brocade net, the prisoner separation roller is reversed first, and the meat machine is poured into a mouth-length, ready to mesh with the silk forest's poorly combed beard. When the forward rotation is accelerated to a certain extent, the pre-woven fabric carded by the forest also reaches the separation clip, meshes with the cotton web tail of the previous cycle of the separation roller loosening, and enters the separation clip together.
At the same time when separation begins to occur, the top comb 10 begins to develop. Due to the tension generated by the pulling of the hair bundle, the hair bundle can be straightened up and inserted into the needle gap of the top comb. When the roller is moving forward, the clumsyly separated fiber bundles are pulled through the needle row of the top comb, so that the tails are combed by the top comb needles, and some short fibers, knots and defects are formed. The whiskers behind the trapped sub-ljii comb will be removed when Xinjinlong combs in the next production cycle. When the nipper reaches the frontmost position, the separation and pressing work ends, the nipper and the top comb start to retreat continuously, and the upper nipper gradually closes, and the preparation is analyzed for the next social work management cycle.
