          About Teppo roving roving upgraded into practical application of computer
          一. Teppo overview of the use machines

          After the mid-1980s to 2000 years ago, the use of multi- cone round cotton roving machine called Lilium roving machine, because Teppo style roving frame in care based on the roving frame has changed significantly , the use of suspended flyer style flyer , to some extent to achieve a roving high-speed , large package and other functions.

          But with the development of the roving machine , Lilium roving machine gradually become evident limitations , Teppo roving biggest drawback : the diameter of the respective winding winding tension is unstable , resulting in instability of the elongation of the roving , which leads to a branched side roving , branched coloring .

          Affected by the following factors in mind:

          1 ) the starting position Teppo belt affected by the human operator , each network roving Teppo initial position of the belt there is uncertainty ;

          2 ) Teppo Teppo between belt and the transmission efficiency and precision of instability by the friction between the belt and Teppo change coefficient ;

          3 ) Teppo shift away from the belt tension by volume and accuracy of matching precision gear effect ;

          4 ) affected by ambient temperature and humidity changes , due to the fiber coarseness , fiber length varies ;

          5 ) set by the process of change, because quantitative roving , twist , twist coefficient of the winding density varies .

          From the user's point of view simply, its limitations are the following :

          1 ) mechanical complexity , equipment adjustment points, labor-intensive operation , maintenance inconvenient, the use of a belt drive gear shift gears more Teppo long run will cause wear and belt damage and other problems , so often need to change gears and Teppo belts, and replacement is very inconvenient, resulting in a larger workload roving machine user maintenance , adjustment more difficult, often irregularly shut down for maintenance , is affecting the spinning efficiency ;

          2 ) Teppo manufactured by molding accuracy, speed causing uneven yarn tension control is unstable , difficult to make Tenders block car will appear irregular and uneven weight roving evenness poor condition that affects roving quality control .

          3 ) process adjustment , heavy workload, try spinning a variety of species to be adjusted 6 gears, spinning close to the design parameters , the adjustment range is narrow, limited range of species to adapt and re- swap varieties need to replace a lot of gear , roving tension adjustment complex , sometimes not now think.

          4 ) Spinning quantitative restrictions: For spinning yarn or special coarse yarn , especially when roving in 3g/10m the following quantitative or 9g/10m more, lifting gear can not meet the normal production density can not be adjusted to the appropriate parameter values .

          To solve the above problems roving machine , we use computers, electronic testing technology and electronics, electrical control actuators and other modern electronic control technology to replace the current regulation by mechanical gear change mode ; roving machine on the transformation of traditional design , the use of CCD line detection and high-precision frequency control technology in the implementation and application of roving machine , roving machine to solve the original Lilium elongation longstanding problems of instability , optimized design, the complex mechanical transmission mechanism more simplified , greatly reducing maintenance work to improve the stability of the equipment , reducing the failure rate ; while using computer technology to achieve online process set , reflecting the quality of the yarn online , online correction settings, etc. to make roving machine has a user-friendly man-machine conversation function, that is, the so-called computer roving machine, so efficient, high quality , automation become the inevitable trend of development , digital, intelligent , information technology development , the roving machine into a new era of digital control , so far four motors, more motor computer roving machine is gradually replacing the traditional cotton Lilium roving machine to become the optimal choice .
