In the early days of the founding of new china, under the guidance of Mao Zedong's revolutionary line, our country developed the 1181 elastic card clothing machine (named a181 when it was changed to the metric system in 1960), with an output of 4-6 kg/kJ. The old factory builds a new factory building for the needs of the equipment. 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. 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. 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 machine has good performance and stable production. With the further increase of the output of the carding machine, the carding of the fibers and the removal of impurities are not enough, which is reflected in the increase of neps and impurities in the carded sliver, and the defects such as cloud spots on the cotton web.
In response to the above-mentioned contradictions of high-yield and high-quality carding machines, under the leadership of the party, the masses were fully mobilized. On the one hand, by rectifying the mechanical condition, strengthening maintenance, rationally configuring process and technological innovation, etc., to tap the production potential of the original organic machine tools to meet the needs of increasing production and spinning year by year, on the other hand, the trial production of metal card clothing has designed a new high-yield Carding machine. From 1958 to 1963, in order to meet the needs of the substantial increase in spinning output, the 1181e metal card clothing carding machine (later changed to a181e type) was studied and tested.
The unit output of this machine is up to 15 kg. At the same time, a batch of 181f metal card clothing carding machines was produced, with a production capacity of 9 kg/unit. Subsequently, a series of production tests were carried out on metal card clothing suitable for high-speed and high-yield carding machines, and the experience in vacuuming, self-stop, splitting, and sliver return devices was further explored, especially for metal card clothing. Specifications were studied to improve the manufacturing quality of metal card clothing, which laid a good foundation for the consolidation and improvement of high-yield cards.
At the same time, the old machine has gradually adopted a new type of elastic card clothing, combined with mechanical rectification and cylinder licker-in acceleration measures, its output has also increased to 10-15 kg/cubit. In 1965, the a185 carding machine was designed and manufactured, and the output was increased to 15-20kg/set. On this basis, the rotating speed of the cylinder licker-in was increased to 360 rpm/motor 1300 rpm/min, and the output of large strip with a diameter of 600 mm and a height of 910 mm reached 20-30 kg/ton.
This model is a186 carding machine, which is a new type of high-yield carding machine required for large-scale production at home and abroad. The great proletarian ideological, cultural and educational revolution has further stimulated the enthusiasm of the vast number of Chinese workers to learn about social capitalism, and they have carried out extensive research and application on old machines, as well as the development of new technologies and techniques for metal card clothing, so that the The output of old machines in less rural areas can be increased to the level of the A186 card. At the same time, Chairman Mao prepares for war, prepares for famine, and serves the people.
Under the guidance of the policy, the A187A small carding machine was also developed. After the enterprise production relationship test, its product quality is similar to the A186 type, and it has resource-saving construction steel. It saves the company's land occupation and facilitates assembly, disassembly, maintenance and transportation. And other advantages, it will now be put into production in batches.
