Abstract.

In the present, grass braiding realizes twisting mainly by hand. Therefore, combined with the process of making braid by hand(Yong Yu.,et,al.(2014),Xianzhe Zheng.,et,al.(2005),Wenming Wang.,et,al.(2015)), single twisting-plying process has been proposed. The grass braid with single twist in the free end(Sheehan M.E.,et,al.(2005)) greatly affects the quality of grass braiding procession and the continuity of feeding is one of the key factors impacting the quality of single twist. The paper designs the grass braiding forming machine of feeding adaptation which includes an active feeding roller, a driven feeding roller and a scraper plate, etc. When the active feeding roller rotates, grass was feeding between the active and the driven feed roller, reaching twisting drum after the projectile motion. The grasping force on the grass between the active and the driven feeding roller can be modified by adjusting the height of the tightening screw . The result shows, the distance between the active and the driven feeding roller can be regulated adaptively according to the feeding amount under the condition that the height of the tightening screw is fixed. In addition, the scraper plate prevents the grass from rewinding to the active feeding roller. The design of grass braiding forming machine with adaptively feeding device can improve the efficiency of braiding.
