The specific embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail.

With reference to the structural representation of the present utility model shown in Fig. 1.

The two-sided upper and lower computer jacquard circular machine of the utility model embodiment, be provided with needle selection jacquard attachment, comprise top cylinder 10, knitting needle 11, pattern bit 12, slide cam selector 20, triangle device 30, be arranged side by side a plurality of needle trays on top cylinder 10, pattern bit head end and knitting needle fasten and are arranged in needle tray.

Pattern bit 12 is provided with sheet tooth 121, slide cam selector 20 is arranged at pattern bit group top, by cutter head 201, coordinate with sheet tooth 121 is movable, when cutter head 201 swings, by the sheet tooth touching under it, corresponding pattern bit is pressed in place's needle tray, and pattern bit is pressed into the structural representation in needle tray as shown in Figure 3, Figure 4.

In the present embodiment, by 8 pattern bits, form one group, and a corresponding slide cam selector, structural representation as shown in Figure 5.

More preferably, be arranged in each sheet tooth on the pattern bit of group position that is staggered and arrange, so that coordinate with slide cam selector, structural representation as shown in Figure 5.

With reference to the structural representation of A portion in the Fig. 1 shown in Fig. 2 and the structural representation shown in Fig. 5, Fig. 6.

Pattern bit 12 tail end tops arrange work heel 122, and the heel 123 that resets, and the support heel 123b that the heel 123 that resets is arranged by the run-out 123a on pattern bit 12 tail ends and pattern bit bottom forms.

Triangle device 30 has comprised elevating cam 31 and reset triangle 32, and elevating cam 31 has raised face 311, and the work heel 122 of pattern bit 12 is endured out by this raised face 311, realizes out pin action.

Before reset triangle 32 is arranged at elevating cam station, for the pattern bit 12 being pressed in needle tray resets.Reset triangle 32 has the run-out of the pattern bit in needle tray is reset to the lifting face 321 on the raised face 311 of elevating cam 31, structural representation as shown in Figure 9, Figure 10, lifting and the supporting role of run-out 123a by 321 pairs of pattern bits 12 of lifting face like this, make pattern bit not be subject to the impact of gravity and fall in needle tray, and make jacquard weave failure, raise the utility model and be better than prior art.

And in order to make the pattern bit 12 after reset can further overcome the effect of gravity to it, in the utility model is implemented, the shape of pattern bit 12 is arranged to arc, structural representation as shown in Figure 7, like this when pattern bit 12 is placed in needle tray, the pattern bit of arc imposes elastic force to needle land, when pattern bit 12 can further overcome the effect of gravity to it by the lifting from needle tray of the lifting face 321 of reset triangle 32 after resetting, make elevating cam 31 to corresponding pattern bit and knitting needle, go out pin action smoothly.

And for pattern bit and knitting needle are better linked, pattern bit 12 head terminations have round hook 124, on knitting needle 11 afterbodys, be provided with the circular groove 111 being rotatably assorted with circle hook 124, as shown in Figure 8 structural representation.

More preferably, pattern bit 12 heads are also provided with draw-in groove 125, are provided with the sheet heel 112 fastening with draw-in groove 125 on knitting needle 11 afterbody terminations.

Referring again to the structural representation shown in Fig. 5.

After jacquard weave has been moved, for knitting needle 11 is regained, above knitting needle 11, be provided with the depressing cam 40 for narrowing, and the pin heel 113 being slidably matched is with it set on knitting needle.

Further, for knitting needle is resetted more accurately, inner groovy 322 is set on the lifting face of reset triangle 32, depressing cam 40 is pressed into the support heel 123b of pattern bit 12 in inner groovy 322 and resets, structural representation as shown in Figure 9, Figure 10.

More preferably, in order to use 11 limit journeys of knitting needle of needle-like state, before depressing cam 40 stations, needle cam 50 is set.

More preferably, the utility model embodiment is also provided with the pin door triangle 60 for needle exchange.

The utility model is when work, slide cam selector 50 optionally makes cutter head 201 press the sheet tooth of its lower corresponding pattern bit according to its input instruction, corresponding pattern bit is pressed in needle tray, even if the work of pattern bit heel departs from the raised face of elevating cam, selected pattern bit is not given prominence to by elevating cam, carried out jacquard weave operation, and when jacquard weave operation completes, by reset triangle, the run-out being pressed in needle tray is carried out to lifting reset, enter to take turns jacquard weave operation.

Above disclosed is only a kind of preferred embodiment of the utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belongs to the scope that the utility model is contained.
