Abstract：
In order to analyze the stress state of the seed cotton in the process of cotton gin and improve the quality of lint, a new model for cotton, namely laminated cotton model, is presented based on the idea of composite laminate. The model assumes that the cotton mass is made up of a certain number of cotton fibers, each of which has a different arrangement angle. Based on this model, the ginning process is simulated using finite element analysis. The mechanical properties of a single cotton fiber either machine-picked or hand-picked are obtained. The working condition of the ginning process is described successfully. By analyzing the influence of different working conditions on the serration cotton ginning process, the simulation results show that model prediction is reasonably consistent with existing experiments. For example, in order to improve the productivity and quality of lint, it is important to guarantee that the saw teeth are sharp and smooth without any crooked teeth or inverted teeth, and the missing teeth on each saw blade shall not exceed the specified value.
