In the carding theory, the choice of the card's diameter of the main components is very important, because it not only affects the size of the machine's diameter occupied, but also has an important and even decisive influence on the effect of grooming. 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). Today, let's analyze the effect of the card's feed roller diameter.
Usually, the feeding roller and the feeding plate together form a feeding tong to feed the lap or cotton stream to the licker-in. In contemporary carding machines, there are two ways of resource allocation and management for cotton feeder rollers: one is the traditional enterprise allocation education method, which is about to allocate technology to the cotton roller market on the cotton feeder board, such as FA203 produced by Qingdao International Textile Machinery Factory Cards, MK5 cards produced by Crosrol. Another way of life is to put the feeding roller under the feeding board, such as Rieter's C51, CSO, C4 cards, and Tefulzler's DK803, 903 cards.
Regardless of the configuration, from the analysis of the actual development in the past 20 years, the feeding roller and the diameter have an increasing trend. For example, the diameter of the feeding roller of the Rieter Cl/3 card is 80 mm, while the diameter of the feeding roller of the C4-A and CSO is 100 mm. The card feeder roller forms a diameter of 80mm. The feeding rollers of German Tefutzler cards from DK2-DK3-DK715-DK74G-DK7BO-DKB03-DK903 are all 100 mm in diameter.
The domestic A18I feeding roller is 57 mm in diameter, while the A201 is 70 mm. The CM80 feeding roller of Howa Company in Japan has been used in the past and we have adopted 70 mm. In recent years, it has become 110 mm. The largest of the inner diameters of the rollers. Because the diameter of the feeding roller gradually increases, the deflection caused by the automatic pressurization of the roller can be reduced, so that students can control the feeding of cotton, make the feeding more uniform and stable, and can also pressurize themselves. amount decreased.
