The metal pin wiring is coiled flat, stamped teeth, and formed after the fire process, shaped like a blade, as shown in Figure 3-29. 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).
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. A list of established or mass-produced metal coil production specifications is listed in Table 3-13. The elastic metal card clothing of the carding machine is bent into a 0 shape with a fine wire, planted on the base cloth according to a certain social organization, and made after bending the knee, side grinding, pressing grinding and throwing fire, as shown in circle 3-30 .
The specifications of the elastic card clothings that have been basically finalized or produced in batches are listed in Table 3-14. Covers with elastic clothing are listed in Table 3-15. In recent years, with the high-speed development and high-yield of the carding machine, the base fabric structure and steel needle of the elastic card clothing have been rounded in the specifications, and it has become a new type of elastic card clothing.
1. Compared with the elastic card clothing, the metal card clothing of the carding machine has the following advantages (1) It can adapt to the high-speed development of the economy, high-yield and strong carding: the metal card clothing has strong teeth, and the gap between the upper and lower dogs is small without bending knees. There are few interstitial fibers, and the load on the needle surface is small, which can meet the requirements of high yield in heavy quantitative research. Due to the hardness of the needle teeth and not easy to deform, it can withstand a large opening force, which meets the requirements of high-yield and strong opening in my country. Because the Chinese metal card clothing is wrapped in a fixed ring, it will not affect the floating phenomenon of the card clothing when the information is high speed, which provides the conditions for the rapid growth of Xinjinlong.
(2) Strong spinnability: The tooth shape specification of metal card clothing can be designed according to process requirements, and it has good spinnability for cotton and various chemical fibers. (3) Long-cycle needle copying: The load on the surface of the metal card clothing is small, and the amount of fibers on the cylinder after the machine is stopped is small. Therefore, if the needle is not stitched for a long time, only the magnetic seeds or hard silk blocks need to be removed regularly, the period of stitching can be greatly extended, thereby eliminating the weight difference between the stop table and the sliver caused by stitching, saving raw materials, raw materials and labor. and number of machines.
