In carding theory, it is very important to choose the diameter size of the carding machine, because the diameter size not only affects the occupancy of the machine, but also has an important and even decisive influence on the effect of carding. The licker-in diameter of the carding machine in most countries is about 250 mm, but some countries are different. 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).
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. For example, the c40 card licker-in produced by Mazzoli in the 1970s had a diameter of 228 mm, and the later c300, cx400 and c501 licker-in rolls were 350 mm in diameter, the largest known card licker-in diameter.
Cz-690 type licker-in diameter is 236mm in Poland, 229mm in the United States, 208mm in Japan, 200mm in China, and 200mm in China. The cards Ok903 and fa225 are the smallest size of the existing card licker-in, they use a triple licker-in system, each with a diameter of 172.5 mm, the smallest known card. The influence of the diameter of the licker-in roll on the following issues: (1) It has an influence on the carding and transfer ability of the fiber.
In general, when the diameter of the licker-in is small and the rotation speed is large, the artistic effect of separating and carding fibers is better, and it is also beneficial to improve the transfer of fibers (especially when we use combing needles). This may be because DK903 and FA225 use small The reason for the diameter of the licker-in. (2) The size of the impact on the clean area. In general, the larger diameter of the licker-in, the large clean area is conducive to the arrangement of the dissolution area and the removal of impurities such as the carding Mazuo Li C501 is larger than 350 mm, which is arranged in the other three groups with the diameter of the licker-in miscellaneous knife dust suction port, Two deflecting blades, 2 carding boards, which are better by the impurities, the working area is completed by 90% of the impurities.
(3) It has an effect on centrifugal force. Generally, when the diameter of the licker-in is designed to be small, under the same linear speed, the centrifugal force will be larger, which is beneficial to improve the transfer of fibers and the removal of impurities.
