Summary of the invention
In order to address the above problem, the invention provides a kind of survey yarn feeding device for circular knitting machine, thereby the length of yarn of braiding use is measured, guarantee the consistent in density of fabric.
Adopt following technical scheme for this reason: a kind of survey yarn feeding device for circular knitting machine, described survey yarn feeding device comprises base, is provided with Ce Sha mechanism and follower on base; Described Ce Sha mechanism comprises main wheel and main axle, and main wheel is connected in base middle part by main axle by bearing fit; Described follower comprises two groups of accessory whorls and accessory whorl axle, and accessory whorl is connected to the top and bottom of base by bearing fit by accessory whorl axle, and described main wheel and accessory whorl are positioned on same center line; It is characterized in that: described survey yarn feeding device also comprises controlling organization, and described controlling organization comprises magnet steel and wiring board, described main axle tail end cover has magnet steel female connector, and described magnet steel is embedded in main axle tail end by magnet steel female connector; Described wiring board is provided with resolving encoder, and described resolving encoder has encoder splicing ear, by encoder splicing ear, resolving encoder is connected with primary control program; Described survey yarn feeding device also comprises density electrical machine and density triangular, and described density electrical machine is connected with primary control program, and described density triangular is connected with density electrical machine; Between wiring board one side and magnet steel, there is encoder induction region, described resolving encoder is passed to primary control program by signal, primary control program compares read value and theoretical value, finds differences and can be spread out of and be adjusted signal to density electrical machine by primary control program, makes it adjust the position of density triangular; Wiring board opposite side is provided with shell, and described shell is fixed by screws on base.
Further, described survey yarn feeding device also comprises an installing rack, and described installing rack 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, encoder splicing ear is connected the resolving encoder on wiring board with primary control program.By the bayonet socket on installing rack, survey yarn feeding device is arranged on circular knitting machine, and the adjustment that can carry out by the bayonet socket of top and bottom diverse location coordinates.Yarn is passed to the accessory whorl of the accessory whorl of base upper end, the main wheel at middle part and lower end successively with S type, under programme-control, main wheel drives yarn to rotate, and in the process of rotating, on magnet steel and wiring board, encoder induction region exports information to primary control program by magnetic induction.The syringe signal of feedback that often turns around, needs the theoretical value of length of yarn to compare institute's reading value and a circle after turning over a circle, and as variant, primary control program feeds back to density electrical machine by information, makes it finely tune the position of density triangular; The syringe reading again that turns around again, repeatedly compares, by repeatedly proofreading, until reach consistent with theoretical value afterwards.Simultaneously can be for the density electrical machine of multichannel, correspondence is installed a plurality of survey yarn feeding devices respectively, then in primary control program, the survey yarn feeding device to each road is numbered, make it to should direction density motor, when so just can realize in circular knitting machine multichannel density electrical machine, adjust, every ranks Density is reached unanimously, effectively improve the weaving quality of fabric.
Accompanying drawing explanation
