Cotton as a very important part of the national economy is closely related to people's daily life and also the important strategyic material. And it puts forward a higher demand of cotton processing. In recent years, although the cotton processing industry in China has made great progress and development and formed a relatively complete industrial system with Chinese characteristics, the level of cotton processing is still far behind developed countries. Therefore, in order to enhance the international competitiveness of our cotton processing industry, it needs to deepen the theoretical study and intelligent and automated research of cotton processing. To this end, the issue designes CNC-type seed cotton cleaning machine based on the study of the principle of seed cotton cleaning in the process of cotton processing, and primarily does the work at the following aspects:1,Further study on the principle of seed cotton cleaning in the process of cotton processing:it includs the study of the principle of seed cotton cleaning and the main models and working principle of the typical structure. Also it analyzes the relationship between the natural physical shape of cotton seed and cleaning efficiency as well as the various factors which affect the seed cotton cleaning efficiency. Thus provides the structural parameters and theoretical basis for the design of CNC seed cotton cleaning machine.2,Design of CNC seed cotton cleaning mechanism:Finish the design of the whole mechanism, including the roller with needing nail and its frame, adaptive mechanism, impurity box, helicoid part and the other connection and suppport structures.Then finish the whole project design of adaptive mechanism.3,The three-dimensional modeling of CNC seed cotton cleaning adaptive mechanism:do the modeling of inclination type CNC seed cotton cleaning machine by Solidworks. And the modeling of adaptive mechanism is transferred into ADAMS software to form a prototype model after parameter settings. Then carry out the simulation to measure the trajectory, and it derives that the designe is reasonable.4,Design of the controller of CNC seed cotton cleaning machine:according to the subject requirements, put forward the overall framework of the system controller design. And analyze the key technologies involved in the system development process-control chip, the cycle pulse distributor and the power amplifier. And design the hardware circuit and the software of the controller,and briefly introduce the application process and functions realization of the system.Through the research work above and eventually complete the study of principles of seed cotton cleaning and the design of CNC seed cotton cleaning machine.This mechanism realizes the basic function of seed cotton cleaning, and adaptive adjustment of the productivity and the speed of the roller and the distance between the roller with needing nail and the lattice bar of inclination type NC seed cotton cleaning machine. It improves the degree of clearing efficiency and intelligent and automation in the cotton processing process so that improves the quality and grade of lint and has brought far-reaching significance for the development of China's cotton processing industry.
