Abstract:

In order to solve the problem of low utilization ratio of the silver can in the process of spinning production of the textile industry, the eccentric belt drive mechanism was developed in this study. First, the equation of motion of eccentric belt drive mechanism was derived, and the law of motion of the driven eccentric pulley was calculated. Then the eccentric belt drive mechanism was used as driving mechanism of coiler. According to the law of motion of the driven eccentric pulley, the initial installation position of the driven pulley was adjusted appropriately to ensure that the coiler rotates fast when the coiler outlet approaches the center of sliver can, and rotates slow as the coiler outlet approaches the wall of sliver can. At last, utilizing the evaluation indicator of linear density, the relationship between eccentricity of the driven eccentric pulley and the capacity increment of the sliver can was analyzed. The result shows that with the increase of value of eccentricity, the capacity increment of the sliver can also increases.
