In order to promote the technical progress of automatic winder,the working principle and application effect of the key technologies of automatic winder,such as high efficient intubation,high speed threading and conveying of bobbin,high speed winding,yarn tension closed-loop control are analyzed,and its development trend is summarized.It is explained that the speed of intubation can be increased by means of CCD and visual inspection technology,automatic turning of bobbin yarn and middle waiting position technology.The grooved winding technology needs to solve the problems such as the relationship between high speed winding and yarn defects,bobbin yarn unwinding and so on.The precision winding system needs to reduce the manufacturing cost of the swing motor.The grid tension control mechanism and the non-rotating ceramic tension disc control mechanism can solve part tension winding problem.The yarn splicing technology needs to develop new splicers and improve the adaptability of varieties.The fixed balloon controller is widely used because of its simple structure and low cost.The problem of length error correction caused by non-same factors is solved by the expert system of precise fixed-length,the work load of workers can be reduced and the forming quality of bobbin yarn can be improved by digital intelligent control technology.It is pointed out that the automatic winder is the key equipment of intelligent spinning workshop and must adapt to the development trend of“unmanned factory”and“black lamp factory”.Artificial intelligence will force the traditional textile manufacturing industry to flexible,digital,intelligent direction to accelerate the transformation.
