The main mechanisms of woolen carding and carding machines consist of three parts: feeding mechanism, carding mechanism, and output mechanism. The main function of the feeding mechanism is to feed the raw materials in a timely, quantitative, and uniform manner. Feeding Mourola has a certain grip and tearing effect on the raw materials. The wool roller has a certain leveling and compacting effect on the raw materials. The sorting mechanism rotates at a speed 100 times faster than the feeding roller, and uses corner nails to tear and loosen the raw materials held by the feeding roller. The tearing and striking forces here are relatively strong. To prevent damage to the fibers, it is generally necessary to choose a reasonable spacing and speed ratio. The loosening effect between Xilin and the work roll occurs in the gripping state of the nail teeth. The inclination direction of the corner nail of the work roll is opposite to its turning direction. When the fiber bundle carried by the teeth of the cylinder nail encounters the low-speed rotating coaxial roll, the intersecting corner nails of the cylinder and the work roll tear and distribute the fibers. In each allocation, the fibers captured by the work roll are peeled off by the hair stripping roll after 1/4 rotation, and then handed over to Xilin for merging with subsequent fibers for the next step of processing. After three cycles of tearing and distribution transfer, the raw materials not only achieved effective sorting, but also obtained a considerable degree of mixing. Output mechanism, the Dove angle nail is slightly inserted into the gap of the Xilin needle for easy grasping and separation of fiber bundles on the Xilin. Due to the high speed of Dove, the four spaced leather strips play a role in striking and scraping the fibers, and also utilize the large airflow generated by them to output the combed fibers outside the machine.
