Abstract: (1), cotton and thorn roller parts. The main function of the cotton and licker portions is to feed the cotton layer into the machine, hold the cotton layer, and remove impurities and lint. The effect of holding the cotton on the cotton portion directly affects the carding effect of the licker roller.(a), the cotton and the thorn roller part.The main function of the cotton and licker portions is to feed the cotton layer into the machine, hold the cotton layer, and remove impurities and lint.The effect of holding the cotton on the cotton portion directly affects the carding effect of the licker roller, so that the grip is required to be firm, the lateral grip is uniform, and the grip force is appropriate. Otherwise, the licker roller will be unevenly combed in the lateral direction, and the quality of the cotton layer of the gripping portion is poor, and the cotton bundle cannot be fully decomposed.The function of the carding magazine of the licker roller. The main function of the licker part is to puncture the cotton layer with the serration of the surface and the serration of the surface of the squeezing plate, and remove the impurities and linters. The quality of the carding directly affects the carding quality of the cylinder cover, and is closely related to the number of cotton knots, the uniformity of the strip and the degree of damage to the fibers. The factors affecting the parting effect of the licking roller are: the speed of the licking roller, the process of feeding the cotton board, the specifications of the squeezing roller, and the process of the carding plate.(b), the cylinder, the cover and the doffer section.The cylinder, cover and doffer parts are mainly composed of cylinders, revolving cover plates, front and rear fixed cover plates, doffers, front and rear cov...
