| Abstract: | Based on the study of the new thread-taking-up mechanism in computerized embroidery machine, the theoretical equations of the solutions to the multi-displacement matrix iteration, the mechanism velocity and acceleration are deduced in this paper. The performance curve of the displacement, velocity and acceleration is analyzed in detail. The conclusion show that the great change of the acceleration is one of the cause to result in the breaking thread in computerized embroidery machine. The method in this paper can be combined to optimize theory to design the parameters of the thread-taking-up mechanism in computerized embroidery machine, the performance curve of the acceleration can be improved to diminish the ratio of the breaking thread. |
