The card is one of the important equipment in the spinning process. It plays a role in the following main processes: (1) The cotton lap (or cotton layer) composed of fiber bundles that is not sent from the cleaning process is not damaged and the fiber On the premise of the premise, in-depth and meticulous opening and carding are carried out, so that the fiber bundles are separated and designed into the development state of single-cell fibers. 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.
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. (2) Removal of said loops (or laps) of impurities such as broken seeds, seed coats, sterile seeds, seed husks, dust, non-spun fibers, combing to open fiber bundles instead of fibers attached to impurities, And has the ability to be recovered in the process of spinning the fibers of impurities.
(3) In the process of opening and carding, the fibers are evenly mixed, and the arrangement method becomes a relatively uniform and extremely thin cotton web, and then the students are collected to become brocade strips (raw strips) with a certain amount of quantification. (4) The finished sliver (sliver) is periodically replayed in the profile sliver, produced for subsequent processing. According to the above basic requirements, in the design of the new high-yield carding machine, by strengthening the carding conditions (using metal card clothing to increase the speed and selecting a reasonable and accurate small gap), the airflow movement of each working part and the card body can be controlled and guided , It also adopts the high-speed stripping mechanism, the continuously variable speed mechanism of the doffer speed mechanism, the large reel winding mechanism and a series of safe automatic parking and automatic devices, so that the new carding machine has reached a new level of high yield, high quality and safety. The key table size and carding process of the carding machine in the cotton spinning industry have greatly reduced the ground occupation, the labor productivity has doubled, and the economic benefits are very significant.
