Technical field
The invention belongs to technical field of knitting machinery, be specifically related to a kind of auxiliary yarn-feeding device of computer plain flat knitter.
Background technology
The yarn-feeding device of computer plain flat knitter is made of major and minor yarn-feeding device, earlier by main yarn-feeding device with the thread feed auxiliary yarn-feeding device, the yarn mouth of the thread feed shuttle box that main yarn-feeding device is fed to by auxiliary yarn-feeding device again, and then by the woven extent of yarn mouth feeding knitting mechanism.
Above mentioned also is that generally the structure of the main yarn-feeding device of use is by shown in Figure 1 in the prior art, and yarn 1 is gone out by unwinding on the yarn tube, at first by twizzle 2, then, yarn 1 from disk tensioner 3 through (by), obtain certain force of strain, then, enter catch the knot device in.The gap of catching knot device 4 can allow the little joint (brief summary) on the yarn pass through, yet when joint is medium joint, medium joint can make the signal of catching 5 vibrations of line device pass to the computer control cabinet, make horizontal volume machine head become low cruise by computerized control system, so that the medium joint on the yarn 1 is enrolled in the fabric by high speed, middling speed; When the joint on the yarn 1 was big joint, the big joint on this yarn 1 was caught line device 5 with promotion and is swung forward, automatic stopping circuit was connected, at this moment the computer plain flat knitter autostop.Then, by entering thread take-up spring 7, thread take-up spring 7 can be provoked surplus yarn to yarn 1 when head commutates, and stable yarn tension effect is arranged from the twizzle 6 of back.Thereafter yarn 1 passes through in the twizzle 8 in the past; enter in the auxiliary yarn-feeding device on the left side of computer plain flat knitter or right side; when line yarn 1 ruptures in the guide process; to upwards swing under thread take-up spring 7 spring action thereunder; contact with its inner broken yarn self-stop device; automatic stopping circuit is connected, at this moment the computer plain flat knitter autostop.
Figure 2 shows that auxiliary yarn-feeding device, auxiliary yarn-feeding device is divided into the left and right sides auxiliary yarn-feeding device again, and both structures are identical.Feed past yarn 1 at first by twizzle 9 by main yarn-feeding device, again by yarn feeding roller 10, then enter disk tensioner 12 and obtain certain force of strain,, yarn 1 is fed in the thread-carrier system in a horizontal manner then by the hook of leading of thread take-up spring 13 by twizzle 11.When yarn 1 broken yarn, thread take-up spring 13 is swing to the right under the effect of its underpart spring, contacts with broken yarn self-stop device 14, makes automatic stopping circuit connect the computer plain flat knitter autostop.In Fig. 2, also show the configuration of thread-carrier, (with one is example at shuttle box guide rail 15, shuttle box guide rail more than one or one can be arranged) forward and backward side shuttle box 16 is installed respectively, is example at this with a shuttle box 16, the bottom of shuttle box 16 has shuttle mouth 18, in the shuttle mouth 18 with yarn 1 can be to the knitting needle pad yarn of knitting mechanism.The yarn of being introduced by sidepiece 1 at first enters the guide porcelain tube 17 on the shuttle mouth 18, enters 18 pairs of knitting mechanisms of shuttle mouth then and carries out yarn feeding, and drive shuttle boxs 16 by the drive link on the head of knitting mechanism 9 and move on shuttle box guide rail 15.
