The quality of the sliver has a great influence on the running performance of the open-end spinning machine and the quality of the spinning technology. 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.
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. 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). Toyota Motor Corporation's recommended system employs a high-throughput card with a shredding cap that shreds the sliver of small amounts of large and foreign matter into fine particles while removing very short fibers and impurities from these fibers.
The use of double carding machines can mainly be used to obtain ideal slivers that are more suitable for spinning through different airflows. After the impurities on the double carding machine need to be treated by the first), the fork enters the second thorn in the world, so that students can obtain sufficient dust control effect. About the difference in the amount of dust in the mug cup, and due to the influence of 8-8, the difference in the quality of the mug yarn within the product.
With eye-carding machines, yarn product miscellaneous cups are minimal, and the extension of time with spinning quality remains little changed. As shown in 8-9, the effect of using various different cards on the airflow jeopardy and broken ends. According to the data of about 10" and 20 counts (Imperial) carried out in Japan, after using the double card, the cleaning cycle of the spinning cup can be extended by 3 to 5 times compared with the company using a common card.
At present, many Chinese textile engineering machinery and equipment manufacturers have designed and manufactured wing interlocking machines that can adapt to different air-powered spinning machines, such as the CKW double interlocking card of the Japanese company Toyota Motor Corporation, the American Sa Clocher type double carding machine, British Crossroller Ker plus double carding machine and the Soviet Union's MJl.-4 double carding machine and so on. Now just take a Japanese CKW type double carding machine as an example to introduce and analyze as follows. The structure of Ckw type double carding machine is shown in Figure 8-10.
Its main specifications are listed in Table 8-3. Main features CKW type double card: 1. The CKW type double card is designed by connecting two CK-7C cards. It is the same as its official model of the double card, which increases the fiber resistance. Carding area and impurity removal area strengthens the effect of carding, opening and impurity removal on the fibers, so that the linters and neps in the sliver are reduced to a low limit, which is beneficial to the air-card spinning machine and less end breakage and Improve the yarn quality and reduce the cleaning volume of the yarn cup. Table 8-4 is the quality management of air-carded yarns spun when using CKW type double carding machine and CE type ordinary carding machine.
2. CKW type double carding licker-in, the diameter of the cylinder and doffer is 20% less common than the card, which is beneficial to improve the efficiency of turning forced carding Xinjinlong significantly, but also because of the more reasonable teeth of the metal wire (11) And support the flat laundry (as shown in Kitchen Stick 12 and in Tables 8-5) to achieve sorting and dare impurities. The fiber transmission efficiency of the doffer cylinder is 3--4 times higher than that of the ordinary carding machine, so at the same time, the yield can also be spun into a better quality pile fabric. 3. The cotton feeding licker-in roller has been greatly developed and transformed (as shown in Figure 8-18), the traditional dust removal knife has been cancelled, the debris drop area has been owed, and the non-porous arc-shaped small leak bottom has been adopted, thus overcoming various dust removal. The shortcoming of the knife disturbing the air flow of the system, completes the internal control of the air flow through the upper and lower parts of the thorn brocade, and promotes the effective separation of impurities and short plucks in the Chinese fiber.
At the same time, the bei under the thorn is concentrated in the transfer belt in the belly of the car, which is sucked by the dust collecting equipment at any time. Suction hood suction.
