Study On The Terry Towel Weaving Device Of Shuttleless Towel Loom

AbstractThe terry towel weaving mechanism is a key component of the loom. Now the domestic factories can only produce the high-quality shuttleless rapier loom and have no ability to manufacture high-quality shuttleless terry loom.The article explains the theory of the terry towel weaving process. Meanwhile this paper analyses several terry motion devices and summarizes the characteristics of the foreign advanced terry towel loom. The completion of terry motion is synthesized by beating-up motion and terry motion. This motion belongs to hybrid driven motion. When you design terry towel weaving device, both beating-up motion and terry motion must be studied. In this paper, the author analyzes the advantages and disadvantages of connecting bar beating-up mechanism and conjugate cam beating-up mechanism. Then the author put forward a new terry towel weaving mechanism which uses connecting bars. This mechanism can be used in conjugate cam rapier loom which is made by the domestic factories.In this paper, the author introduces some general motions of beat-up mechanism. With the application of the reverse design principles, the author builds mathematical model of conjugate cam motion. According to the discrete three-coordinate values and the terms of geometry of this part, the original design parameters of beat-up motion are restored. Then we can find out the movement law of the weft knitting system.In the chapter 4, the author analyzes the flow of the movement between beating-up motion and terry motion. This article optimizes the length of the terry towel weaving bars. Then the author analyzes the relation among terry height, reed stroke and Loop-pile rotation angle of the bar.Zhang yong (Mechanical Design and Theory) Supervised by Prof.Li jinhai...
