It does not use spindles and mainly relies on multiple components such as carding rollers, spinning cups, and false-twist devices to work. The carding roller of air-jet spinning is one of the main components in air-jet spinning machinery. Its core function is to separate and comb the fibers ejected from the nozzle to make them into long and uniform fiber bundles, facilitating subsequent textile operations. However, the current carding roller still has the following deficiencies:

[0003] For example, the patent document with the publication number CN215668345U discloses an air-jet spinning carding roller. For this air-jet spinning carding roller, by taking out the replacement tooth block inside the card slot and then installing a new replacement tooth block, the purpose of replacing the damaged roller pins can be achieved, and there is no need to replace the entire device, greatly saving the consumption of funds. Moreover, the replacement tooth block can be quickly clamped with the sealing plate through the top clamping block, enhancing its use stability. It has the advantage that the roller pins can be replaced, but it cannot maintain stability during rotation, has poor smoothness, and the rotation is not smooth enough, easily leading to a decline in processing efficiency and quality.
