The fiber Polyester Color Yarns factory transferred from the cylinder by the cylinder is first thrown to the fixed cover plate, which has a strong effect and is easy to damage the fiber. From large to small; the use of gradual spacing can make the fiber realize displacement between the cylinder and the fixed cover plate.23mm.2 Re-quantitative carding quality and problems with the process The output has increased, and the amount of carded fibers per unit time has increased several times. The distance between the cylinder and the cover plate should be determined by the state of the adhesion surface of the fiber on the cylinder surface, which mainly depends on the following factors: (1)

The surface linear velocity of the cylinder, the higher the cylinder speed is, the higher the cover plate is. Therefore, if we only increase the output of the carding machine in terms of increasing the delivery speed, it will be subject to the carding quality and the drawing capacity of the subsequent process, and the quantitative increase cannot achieve a breakthrough. Under the condition of heavy weight,

the amount of fiber carried by the cylinder card clothing increases, the needle surface load increases, the cylinder speed increases, and the thickness of the air flow of the surface layer increases. 2. But the heavy weight process is not simply to improve the sliver weight, but on the basis of satisfying the carding effect of the fiber, give full play to the mechanical and technological efficiency of the carding machine, so that the drawing quality of the subsequent process is not affected.3 Design points of the pre-carding board-spur roller, dust-knife-prick roller spacing

The pre-separating board can pre-open the fiber bundles, reducing the carding load in the main carding area.22, 0.20mm from top to bottom. The focus is on improving the fiber transfer effect and reducing quality fluctuations. (4) The longitudinal tooth pitch of the needles of the cylinder clothing is large, and the rear end of the fiber is not easy to be controlled and it is easy to rise. When the defect content of the raw material is high, moderately increasing the speed of the cover plate has a significant effect on reducing the content of sliver defects.71-0. See
