Abstract
The utility model relates to a weaving cam mechanism which is characterized by comprising a fanning plate, a high plate upper needle and a low plate upper needle, wherein the high plate upper needle and the low plate upper needle are inserted into an upper needle tube needle groove one after another. A needle head of the high plate upper needle is lower than a needle head of the low plate upper needle. The upper portion of the fanning plate is tightly fixed with a needle lifting cam and a needle flattening cam. The lower portion of the fanning plate is tightly fixed with a back needle cam and a needle pressing cam. A needle motion step is arranged at the lower end of the needle lifting cam. A first upper needle pin and a first lower needle pin are arranged on one side of the high plate upper needle, wherein the side of the high plate upper needle is towards the needle lifting cam. A second upper needle pin and a second lower needle pin are arranged on one side of the lower plate upper needle, wherein the side of the low plate upper needle is towards the needle lifting cam. The upper surface of the first upper needle pin is contacted with the lower surface of the needle motion step on the needle lifting cam, and moves along the lower surface of the needle motion step. The second upper needle pin is matched with the needle motion step of the needle lifting cam, and can move along the needle motion step. According to the weaving cam mechanism, yarn hooking effect with hooking one separated by three is achieved, and therefore thick yarn can be woven.
Description
Technical field
The utility model relates to a kind of knitting cam mechanism, and a kind of upper knitting mechanism on especially a kind of jacquard weave snow Neil circular knitting machine belongs to technical field of textile machine.
Background technology
In the middle of the prior art, the upper knitting mechanism that adopts on the jacquard weave snow Neil circular knitting machine is single knitting needle, and rise cam can only realize going out pin every a pin.And in braiding during than the chenille yarn of roving count, need the relatively general knitting needle of knitting needle corresponding on the braiding machine not only greatly but also long, on the needle plate on the general needle plate of the gap ratio of needle tray the needle tray spacing want large.Present jacquard weave snow Neil circular knitting machine can't weave the chenille yarn than roving count, also can't accomplish the jacquard effect than Gao Maogao, can not adapt to client's demand.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of knitting cam mechanism is provided, and has effectively solved the braiding than the roving count chenille yarn.
According to the technical scheme that the utility model provides, described knitting cam mechanism is characterized in that: comprise fanning strip and with pin on pin and the low plate on the high plate in a mode inserts in the top cylinder needle tray, the needle position of pin is lower than the needle position of pin on the plate on the high plate; The fastening rise cam peace pin triangle on described fanning strip top is at the fastening back-stitching cam in fanning strip bottom and depressing cam; Lower end in described rise cam arranges the step that takes the needle, and pin arranges stitch and first time stitch on first towards a side of rise cam on high plate, and pin arranges stitch and second time stitch on second towards a side of rise cam on the low plate; The lower surface of the step that takes the needle on described first on the upper surface of stitch and the rise cam contacts, and moves along the lower surface of this step that takes the needle; Stitch matches with the step that takes the needle on the rise cam on described second, and along the step movement that takes the needle.
The surface of described rise cam is for walking dial.
Stitch and second time stitch are all between back-stitching cam and rise cam on stitch on described first, the first time stitch, second.
Be plane contact between the pin on pin and the low plate on described flat pin triangle, back-stitching cam and the high plate.
The beneficial effects of the utility model are: one every three hook yarn effect when the utility model can be realized jacquard weave automatically, thereby can weave thicker yarn, and realized the braiding than Gao Maogao; And the utility model has adopted the different two kinds of knitting needles of stitch height mutually to be arranged alternately, and can do one every one braiding, to adapt to the production than fine yarn, also can do one every three braiding, adapts to the production than coarse yarn.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
Such as Fig. 1 ~ shown in Figure 3: as described in knitting cam mechanism comprise on flat pin triangle 1, rise cam 2, back-stitching cam 3, the low plate on pin syringe needle track 4, the high plate on pin syringe needle track 5, depressing cam 6, the high plate on stitch 7-1 on the pin 7, first, first time stitch 7-2, the low plate stitch 8-1 on the pin 8, second, second time stitch 8-2, fanning strip 9, step 10 etc. takes the needle.
As shown in Figure 1, the utility model comprises fanning strip 9 and with pin 8 on pin 7 and the low plate on the high plate in a mode inserts in the top cylinder needle tray, pass through screw fastening rise cam 2 peaceful pin triangles 1 on fanning strip 9 tops, by screw fastening back-stitching cam 3 and depressing cam 6, the surface of described rise cam 2 is for walking dial in fanning strip 9 bottoms; The needle position of pin 7 is lower than the needle position of pin 8 on the plate on the described high plate, thereby, when machine run, top cylinder drives on the high plate pin 7 runnings and moves along walking dial, the syringe needle of pin 7 is walked out pin syringe needle track 5 on the high plate on the high plate, and the syringe needle of pin 8 is walked out pin syringe needle track 4 on the low plate on the low plate;
Such as Fig. 2, shown in Figure 3, the surface of described rise cam 2 arranges the step 10 that takes the needle for walking dial in the lower end of rise cam 2; Pin 7 arranges stitch 7-1 and first time stitch 7-2 on first towards a side of rise cam 2 on described high plate, and pin 8 arranges stitch 8-1 and second time stitch 8-2 on second towards a side of rise cam 2 on the described low plate; Stitch 8-1 and second time stitch 8-2 are all between back-stitching cam 3 and rise cam 2 on stitch 7-1 on described first, the first time stitch 7-2, second; The lower surface of the step 10 that takes the needle on described first on the upper surface of stitch 7-1 and the rise cam 2 contacts, and moves along this lower surface that takes the needle step 10; Stitch 8-1 matches with the step 10 that takes the needle on the rise cam 2 on described second, and moves along the step 10 that takes the needle;
Be plane contact between the pin 8 on pin 7 and the low plate on described flat pin triangle 1, back-stitching cam 3 and the high plate.
Operation principle of the present utility model: when not needing jacquard weave, chenille yarn simultaneously by pin 8 eats on pin 7 on the high plate and the low plate into; When needs carry out jacquard weave, lower pin withdrawal of needle on the bottom cylinder hooks chenille yarn, and this moment is under the effect of lower pin, pin 7 on the high plate is because needle position is lower than the needle position of pin 8 on the plate, running position is relatively low, can hook together chenille yarn with lower pin, and pin 8 is higher owing to needle position on the low plate, then hook is less than yarn, in fact formed upper pin one every three hook yarn mode, so also just realized bodkin apart from withdrawal of needle, thereby can weave the chenille yarn than roving count.
The utility model processes the step 10 that takes the needle in the bottom of rise cam 2, and on the high plate between the pin 7 interval be provided with pin 8 on the low plate, on on should low plate on the pin 8 second on the position relative first of stitch 8-1 stitch 7-1 higher, efficiently solve the braiding than roving count snow Neil and Gao Maogao, satisfied market demand.
