Summary of the invention

In order to overcome the deficiency that thread-carrier on the existing weft-knitting machine is difficult to accurately be positioned at a certain ad-hoc location pad of knitting needle yarn, provide pad sliver spare for developing weft-knitted new product, the utility model provides a kind of thread-carrier and positioner that is used on the weft-knitting machine, this thread-carrier and positioner be the locating pad yarn accurately, and can not damage knitting needle, can also after entrying easily and entrying, the lapping position accurately reset temporarily easily.

The technical scheme that its technical problem that solves the utility model adopts is: adopt the elongated tubular product such thread-carrier, stretch nearly knitting needle as far as possible and feed the ad-hoc location that arrives knitting needle with yarn guiding pad, to satisfy the requirement of the institutional framework that is woven.This elongated tubular product such thread-carrier carries out space orientation by V shape grip slipper and screw mandrel rackwork, the recovery of the normal pad yarn weaving position after being entried easily by the ball detent mechanism.

The beneficial effects of the utility model are: can accurately be positioned at a certain ad-hoc location pad of knitting needle yarn in the braiding, carry out space orientation easily and reset; Simple in structure, adjust simple and easy to do; The space occupy-place is little, and can make has threads to fill up yarn by different way on same road to become simple and reliable.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structure and the action principle figure of thread-carrier parts of the present utility model, is example to be installed on the dials Triangulum 6.Thread-carrier can carry out space orientation pad yarn exactly to knitting needle.

Fig. 2 is the special use device action principle figure that entrys.After thread-carrier 1 is installed on the machine, the position compactness, surrounding space is less, for elongated tubular product such thread-carrier 1 is penetrated yarn, has designed the special use device 2 of entrying.

Fig. 3 and Fig. 4 are the yarn feeder block devices that spring marble location is arranged, be adapted to be mounted within on the dials Triangulum 6 respectively and syringe Triangulum 15 on.When the yarn in the thread-carrier in braiding because accidentalia is had no progeny, for ease of entrying, thread-carrier must be changeed and withdraw from pad yarn zone (shown in arrow among the figure), put on yarn after, must accurately reset again in the lapping position.For this reason, design the yarn feeder block device of this spring marble location.

1. elongated tubular product such thread-carriers among the figure, 2. entry device, 3. yarn, 4. dials yarn feeder block, 5. holding screw, 6. dials Triangulum, 7. the fulcrum screw is 8. located making leaf spring, 9. positioning ball, 10. making leaf spring is installed screw, 11. interior top dog screws, 12. location stage clips, 13. positioning screw cap, 14. syringe yarn feeder blocks, 15. syringe Triangulums, 16. the dials knitting needle, 17. cylinder knitting needles.

The specific embodiment

In Fig. 1, thread-carrier 1 shown in Figure 3 are installed in embodiment on the dials Triangulum 6, for making thread-carrier 1 accurately carry out space orientation pad yarn feeding line 3 to dials knitting needle 16, the structure of thread-carrier device is as follows: installing tubulose thread-carrier 1 with screw 5 on yarn feeder block 4.Yarn feeder block 4 just can rotate around fulcrum screw 7 together with the thread-carrier on it 1, and can be located at a certain operating angle state by location making leaf spring 8 and positioning ball 9, and the requirement of yarn is filled up in entrying and resetting when satisfying the machine normal operation like this.In the initial adjustment of tubulose thread-carrier 1 lapping position, because of location about narrow, especially the distance between dials Triangulum 6 and the cyclinder needle 17 is less, and only must be therebetween to the thread-carrier 1 of coverer 16 pad yarns, this just can't lock the position of fulcrum screw 7 with the form of nut, has to interior top dog screw 11 locking devices fulcrum screw 7 be located at any rotation angle.During adjusting, screw off earlier fulcrum screw 7 and on parts such as yarn feeder block 4, top dog screw 11 advances or retreats in making again, and then fulcrum screw 7 peaces are gone into and holds out against the operating position that locks fulcrum screw 7 like this and go up thread-carrier 1 with interior top dog screw 11.Can regulate until the exact position repeatedly.

In thread-carrier shown in Figure 41 is installed in embodiment on the syringe Triangulum 15, because of the distance between syringe Triangulum 14 and the coverer 16 bigger, for making thread-carrier accurately carry out space orientation pad yarn feeding line, just comparatively convenient on Design of device to cylinder knitting needle 17 (referring to Fig. 1).Only list cylinder knitting needle thread-carrier device and dials knitting needle thread-carrier device difference structurally below: yarn feeder block 14 can rotate around fulcrum screw 7 together with the thread-carrier on it 1, can be located at a certain operating angle state by location stage clip 12 and positioning ball 9, the requirement of yarn is filled up in entrying and resetting when satisfying the machine normal operation like this.Because of the position allows, the any rotation angle location of yarn feeder block 14 can lock the position of fulcrum screw 7 simply with the form of positioning screw cap 13, during adjusting, unscrew nut 13 earlier, transfer circumflex branch axle screw 7 then, yarn feeder block on it 4 is adjusted to the appropriate location, and screwing nut 13 again is the operating position of lockable fulcrum screw 7 and last thread-carrier 1 thereof.Can regulate until the exact position repeatedly.
