0 0.05Mm, needle body height be 5 ±
0 0.05Mm, shank length is 115.2mm.The utility model is at innovative point related on the bodkin cross weaving needle: on (3-6 pin/inch) knitting needle, adopted narrower needle body thickness at bodkin; Make knitting needle thickness be minimized 1.80mm; And short knitting needle total length 115.2mm, help the manufacturing of knitting needle, the manufacturing of knitting needle and the milling of needle-bar needle tray.
Shown in Fig. 1-4; A kind of bodkin is apart from cross weaving needle; Described knitting needle comprises that the knitting needle needle body 1, the flat-knitting machine head triangle that is used for that is equipped with in the knitting needle needle body 1 right ends respectively promote down, drive knitting needle and in the needle-bar groove, move up and down with the pin of accomplishing a series of skill of handling needles such as braiding, tuck, barring-on, adapter ring call in person 1a and pinhock 1d; From left to right be equipped with side direction breach 1b on the described knitting needle needle body 1 successively and the needle body 1 bent to certain angle in this; When being moved up and down, knitting needle has certain damping in the needle-bar needle tray; When knitting needle has broken away from the control of flat-knitting machine head triangle, can not make it to be subjected to displacement by the effect of gravity or coherence because of being positioned at tilting straight-bar machines needle-bar needle tray; In the needle body 1 part device expand circle sheet 3 (being commonly called as " turning over faller gill "); When making coil between the needle-bar of front and back, shift (also name " barring-on " or " turning over pin "),, penetrate in order to the adapter ring pin with old coil expander; The utility model has been taked the design of band radian; Make it when turning over pin more accurately and reliably, the needle body 1 be positioned at expand circle sheet 3 below, have the barring-on breach 1c that supplies the adapter ring pin to get into; At the needle body 1 head, be provided with that to rotate folding, effect around centrepin be to slough the needle latch 2 of old coil and the pin that cooperates with needle latch 2 colludes 1d.The needle body 1 thickness of the utility model is 1.8 ±
0 0.05Mm, the needle body 1 highly be 5 ±
0 0.05Mm, shank length are 115.2mm, and key dimension is: pin heel 1a width 4.5mm, height 11.8mm; Expand circle sheet 3 and add the needle body 1 gross thickness 3.23mm; Pin colludes 1d diameter phi 5.2mm, colludes thick φ 1mm; Have expansion circle breach 1e at the needle body 1 middle part; When coil is shifted between the needle-bar of front and back yarn tension obtain part alleviate, when reducing barring-on (turning over pin) extent of damage of yarn, knitting needle and knitting needle placed in the needle tray on the needle-bar 4 before and after 5 minutes, the knitting needle pin is called in person and is exposed needle-bar 4 surfaces; Receive in needle tray, to horizontally slip under the effect of head triangle and knitting needle 5, to accomplish braiding, tuck, to turn over various skill of handling needles motions such as pin, adapter ring.
As shown in Figure 3, be equipped with pin heel 17b and knitting needle needle selection tooth 17c under knitting needle top butt 17a, the knitting needle on the described knitting needle 17.
Shown in Figure 11-12; The described bed system 28 that moves is equipped with the right side at needle-bar 21; Comprise being located to be movably set in and move riffling 28a on lathe bed 15 grooves; The described riffling 28a middle part moved has and is used to be equipped with the dovetail groove 28d that moves a slide block 28c, and a described slide block 28c that moves is connected by bolt with the clever 28b of the work of ball-screw 28e, and described ball-screw 28e is connected with servomotor.During work; Ball-screw 28e rotates and drives clever 28b alive and move riffling 28a move left and right in lathe bed 15 grooves through a slide block 28c drive that moves that is fixedly connected with the clever 28b that lives; Move a slide block 28c and move riffling 28a because of the spirit alive that is attached thereto has boss to block, thereby guarantee and move that the inclined-plane is connected reliably tight between a slide block 28c.The utility model moves riffling and moves innovative point related on the slide block structure and be at the bodkin straight-bar machines: keeping moving riffling and moving about a slide block to the close-fitting while, making to move a slide block and move between the riffling has certain floating space at above-below direction.Install when not parallel when moving between riffling and ball-screw at above-below direction, moving a spirit alive can fluctuate.With respect to moving the riffling and being fixedly connected between spirit of living, the scheme of the utility model can effectively protect screw mandrel not receive normal tension.Thereby can obviously reduce the spoilage of leading screw, guarantee the smooth operation of equipment.
Shown in figure 13, for needle-bar and knitting needle, the knitting needle of the utility model cooperates figure, knitting needle 7 places in the right-hand knitting needle groove of the needle-bar 2a among the figure; Its top receives tent 4 restrictions, under knitting needle thimble end 6d and its knitting needle pin heel of triangle effect 7a, in needle tray 2a, does translational motion; Knitting needle 6 places in the needle-bar left side knitting needle groove, and its top receives down tent 5 restrictions, under pin heel 6a and knitting needle top butt 6b under its knitting needle of triangle effect; In jacquard weave needle tray 3a, do translational motion; Before needle selection device needle selection, jacquard weave is lifted the pin triangle knitting needle is lifted in needle tray, makes the knitting needle top butt 6b of knitting needle, knitting needle needle selection tooth 6c expose the needle-bar surface and wait needle selection.
Shown in figure 14; When knitting needle is in candidate regions; Corresponding needle selection device cutter head at the electromagnetic control apparatus control bottom to the right, pin heel 6a to right translation, moves right to accomplish through the moving knitting needle of knitting needle thimble end 6d and lifts needle movement under needle-bar surface, effect at triangle under the knitting needle.
Shown in figure 15; When knitting needle is in candidate regions, corresponding needle selection device cutter head is in vertical position under electromagnetic control apparatus control, and then knitting needle is lowered into position as shown in Figure 4 in the needle-bar in the compacting of needle selection device cutter head 8; Pin heel 6a sinks in the needle-bar under the knitting needle; So, inoperative to it when head drives triangle through this knitting needle, thus the knitting needle of top is not worked.
