(1) The purpose of pressurizing the cotton roller by the carding machine is to strengthen the holding method of the cotton layer. 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. 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. 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.
The pressurization weight of the A186 carding machine to the cotton roller is 3.8-5.4 kg/cm (including the weight of the structure). The pressurization of the cotton roller of the 01I81C type has been improved in recent years. (2) The pressure of the big root has little change in pressure. In general, cotton spinning is pressurized by its own weight, and chemical fiber spinning is pressurized by spring, and the pressure is generally 10-20kg. Reasonable selection of carding elements The choice of carding elements (card clothing, buttons, sliver) is a key factor in determining the quality of the carding machine.
(A) Card selection of flexible thread 1. Processed to form short fibers, when spinning high-gauge yarn, the number of metal card clothing should be smaller. On the contrary, when spinning slender structural fibers, the new card clothing number should be higher when spinning low-gauge yarn. out some. 2. Using digital doffer, the fabric should usually be less than the 10-20 gauge cylinder stitch count, the stitch count is a dog, the higher the number of doffer transfer rates. (2) Choose a flat card clothing The company can choose and flat card clothing according to the type of Jinlin card clothing and different types of processing and production raw materials.
Jinlin is an elastic card clothing. When spinning low-gauge yarns and medium-sized enterprises, the use of fine-needle and high-density cap pole clothing is used. Xinjinlong is a metal card clothing. When spinning medium-sized yarns such as polyester, the cover plate is made of straight card clothing with thicker ordinary steel needles and smaller needle density. Xinjinlong is a metal card clothing, spun cotton medium yarn, when the output is medium, the cover should be selected as the curved foot cover card clothing with finer steel needles and higher needle density.
When choosing movable flat card clothing, the principle of hard matching hard, soft matching soft, and close matching is often used. For elastic card clothing carding machine, the number of cover pole clothing should be higher than that of Xinjinlong clothing. (3) The selection of metal card clothing should be determined according to the nature of raw materials, spinning quantity and output.
(4) The licker-in saw blade should be selected according to the output and the performance of the raw materials.
