The specific embodiment
Be described in further detail below in conjunction with the structure and the course of work of accompanying drawing the utility model crochet machine head:
As Fig. 1, shown in, a kind of crochet machine head comprises the syringe mandrel 1 that is fixed on the frame, frame is not drawn in the present embodiment.The middle part of syringe mandrel 1 is provided with the passage 2 that connects its two ends, the outer surface of syringe mandrel 1 is provided with several and syringe mandrel 1 axial identical needle tray 3, syringe mandrel 1 is arranged in the headstock 5 by bearing 4, be provided with space collar 6 between the two bearings 4, space collar 6 is set on the syringe mandrel 1, play the effect of location, be provided with the pair of end face cam in the headstock 5---upper end cam 7, lower surface cam 8, on, lower surface cam 7,8 between syringe mandrel 1 and headstock 5, and headstock 5 is with last, lower surface cam 7, be fastenedly connected by lock-screw 9 between 8.As shown in Figure 2, on, lower surface cam 7, form chute 10 between 8, described chute 10 has two crests and two troughs, it is linearly that chute between adjacent peaks and the trough launches the back, the chute at crest and trough place is a curve-like, two crests and two troughs are respectively about the central axis symmetry of edge cam, yarn feeding seat 11 is fixed on the top of upper end cam 7 by lock-screw 12, the top of yarn feeding seat 11 is provided with 13, crossing yarn device 14 is arranged on the yarn feeding seat 11 by bearing 15, bearing 15 radially both sides is respectively arranged with adjustment screw 16, adjustment screw 16 with take over a business 13 and be threaded and contact with bearing 15, cross yarn device 14 and be provided with three thread guide eyelets 17,18,19, cross yarn device 14 and be provided with fixed bar 20, the both sides of the other end of fixed bar 20 are respectively arranged with bumping post (not drawing among the figure), when having served as the central axis rotation of yarn device 14 whole cast-over tube mandrels 1, the autobiography amplitude of crossing yarn device 14 is very little under the effect of fixed bar 20 and bumping post, guarantees that yarn can accurately feed corresponding separately knitting needle.The last axle head of syringe mandrel 1 is provided with a gap 21.
As shown in Figure 3, first embodiment of the present utility model is provided with a blade pin 22 in the needle tray at gap 21 places---and as shown in Figure 4, gap 21 has strengthened the cut coverage of blade pin 22, make yarn be not easy to concentrate on one, cut off easilier by blade pin 22.Be provided with knitting needle 23 in the C place needle tray, the head of blade pin 22 and knitting needle 23 is respectively arranged with pinhock 24,25, the afterbody of blade pin 22 and knitting needle 23 is respectively arranged with slide plate 26,27, slide plate 26,27 all is positioned at chute 10, pinhock 24 belows of blade pin 22 are provided with corresponding cutting edge 28, and pinhock 25 belows of knitting needle 23 are provided with corresponding needle latch 29;
As shown in Figure 5, second kind of embodiment of the present utility model is respectively arranged with knitting needle 23 in the needle tray at A, B, C place among the figure;
As shown in Figure 6, the third embodiment of the present utility model is respectively arranged with knitting needle 23 in the needle tray at A, C place among the figure.
The course of work of this crochet machine head is as follows: with three one threads---and after yarn 1, yarn 2 31, yarn 3 32 led from former creel respectively, yarn 1, yarn 2 31, yarn 3 32 entered in the passage 2 of syringe mandrel 1 by thread guide eyelet 17,18,19 respectively.The layout of thread guide eyelet 17,18,19 must satisfy: regulated the position of yarn device 14, and made headstock 5 rotate a circle, the feeding state of yarn is: the knitting needle at A place can be hooked to yarn 2 31, yarn 3 32; The knitting needle at B place can be hooked to yarn 2 31; The knitting needle at C place can be hooked to yarn 1, yarn 2 31; Blade pin 22 can be hooked to yarn 2 31.Starter motor drives headstock 5 rotations, headstock 5 drives upper end cam 7 and 8 rotations of lower surface cam, slide plate 26 on blade pin 22 and the knitting needle 23,27 will slide along chute 10, because syringe mandrel 1 is fixed on the complete machine, so the rotation of edge cam will be converted into blade pin 22 and knitting needle 23 rectilinear motion up and down along needle tray 3, simultaneously because chute 10 has two crests and the trough of symmetry, so the action of two knitting needles on the same diameter will be the same, rise simultaneously and descend simultaneously, guaranteed in production wide cut rail yarn two warps crocheting simultaneously of wide cut rail yarn.If knitting needle is arranged as shown in Figure 3, the knitting needle at yarn 1, yarn 2 31 feeding C places, yarn 2 31 feeds blade pin 22 again and is cut off by the cutting edge 28 of blade pin 22 simultaneously, has just formed the wide cut fluffy yarn; If knitting needle is arranged as Fig. 5, A, B, C place all are provided with knitting needle, and yarn feeding state is: the knitting needle at A place can be hooked to yarn 2 31, yarn 3 32; The knitting needle at B place can be hooked to yarn 2 31; The yarn at C place can be hooked to yarn 1, yarn 2 31,3 32 on yarn twines on A place knitting needle and forms warp, one 30 on yarn twines on C place knitting needle and forms warp, yarn 2 31 twines a circle and forms parallel, twine on B place knitting needle simultaneously and form warp, what produce is exactly double-deck wide cut rail yarn; If knitting needle is arranged as shown in Figure 6, A, C place are provided with knitting needle, and the knitting needle at A place can be hooked to yarn 2 31, yarn 3 32; The yarn at C place can be hooked to yarn 1, yarn 2 31, and 3 32 on yarn twines on A place knitting needle and forms warp, and one 30 on yarn twines on C place knitting needle and forms warp, and yarn 2 31 twines a circle and forms parallel, and what produce is exactly individual layer wide cut rail yarn.The yarn of being produced is pulled all that device pulls out and rolling in the passage 2 of syringe mandrel 1.
The utility model has the advantages that: it is effectively straight that the crochet machine head of employing said structure can dispose needle tray The bigger syringe mandrel in footpath, and do not affect the stationarity of whole head rotating, thus can produce wide cut rail yarn, The wide cut fluffy yarn.
