ABSTRACT 
  High-speed color toothbrush tufting machine is improve efficiency and advanced processing equipment of toothbrushes.Greatly improved production efficiency,production quality, production varieties. Efficiency than the original manual operations increased by 6 to 7 times，completion 15000 amounted to 20000 Toothbrush in every day，great to meet the needs of the market.and achieved good economic.The purpose of this project is to make the link between each process, and enhance the degree of mechanization to reduce labor participation, both to reduce costs and to improve the efficiency of a production.
  After considering a combination of the above,I will be the topic of this design is the high-speed color toothbrush tufting machine mechanical structure design.Design of the main uses CAD, Solidworks and other engineering drawing software for drawing and structural analysis. And some important components necessary calculations and verification.
