Further, described survey yarn feeding device also comprises an erecting frame, and described erecting frame is provided with at least one group of upper end bayonet socket and lower end bayonet socket.

Further, described follower also comprises a cover plate, and described cover plate is fastened on accessory whorl.

According to such scheme, the resolving encoder on wiring board is connected with primary control program by scrambler splicing ear.By the bayonet socket on erecting frame, survey yarn feeding device is arranged on circular knitting machine, and the adjustment cooperation of diverse location can be carried out by the bayonet socket of top and bottom.By yarn with S type successively through the accessory whorl of the accessory whorl of base upper end, the main wheel at middle part and lower end, under program, main wheel drives yarn to rotate, and in the process of rotating, on magnet steel and wiring board, scrambler induction region exports information to primary control program by magnetic induction.Syringe often turns around feedback signal, and need the theoretical value of length of yarn to compare institute's reading value and a circle after turning over a circle, as variant, information feed back to density electrical machine, makes it finely tune the position of density triangular by primary control program; Syringe turns around reading again more afterwards, repeatedly compares, by repeatedly proofreading, until reach consistent with theoretical value.Simultaneously can for the density electrical machine of multichannel, the multiple survey yarn feeding device of corresponding installation respectively, then in primary control program, the survey yarn feeding device on each road is numbered, make it to should direction density motor, this makes it possible to realize adjusting while multichannel density electrical machine in circular knitting machine, make every ranks Density reach consistent, effectively improve the weaving quality of fabric.
