1、控制工程根底论文英中对照翻译专业：学号： 姓名：Machinery control applications in the modern textile industrySome years, as people more conscious of the aesthetic and living standards, high-grade yarn-dyed products are increasingly popular. Not real silk, chemical fiber, rayon, cotton yarn, also can be blended and Silk wea
2、ving, dyeing bobbins which led the industry in the yarn is widely available. General yarn before dyeing tube blanks need to be purchased to suit the yarn package dyeing contact with the pine-style cheese for the next procedure to use, so slack increasing demand for precision windingExisting domestic
3、 slack winding machine structure is generally focused on single-spindle drive mode, usually including winding, yarn, over-feed, such as several sports, the use of mechanical gears and cam completion, for a variety of yarns of different winding process, equipment is more difficult to adjust; yarn org
4、anizations to adopt a grooved drum and rotary wing, for some high-end yarn is easy to produce injury; the same time as the structure is used in mechanical transmission, winding speed is not high. This pine-style winding currently abroad has been completely based on electronic gear and all digital el
5、ectronic cam winding structure, namely, the independent single spindle drive; winding, traversing yarn guide, yarn over-feed, tension compensation are used separate motor control the movement of the relationship between the motor can be described by parameter setting, flexible response to various ch
6、aracteristics of the yarn winding process needs; traversing yarn guide used the yarn guide, commonly known as rabbit head , damage to the yarn is very small, especially for high-grade yarn-dyed yarn winding; In addition, as the motor drive there is no direct mechanical connection, combined with high
7、-speed precision motion control software algorithms, can easily achieve high precision cross-winding, winding speed of winding is much larger than mechanical slack, greatly improving the efficiency of the windingBeijing and Li Technology Co., Ltd. through the motor and domestic well-known textile ma
