Abstract
The pressure bar of a kind of spun yarn first break draft of the utility model zone swiveling wheel, comprises pin sub-assembly, and the upper pin of described upper pin sub-assembly is staggeredly equipped with downforce rod, upward pressure rod, and described downforce is excellent, upward pressure is excellent is respectively arranged with relative drop center wheel.The utility model structure is simple, and manufacture, production cost is low and production does not need additional energy, it can significantly improve spinning yarn quality and production efficiency, has low cost, high efficiency double dominant, is suitable for textile enterprise and uses.
Description
Technical field
The utility model relates to Weaving device, is specifically related to a kind of pressure bar of spun yarn first break draft zone swiveling wheel.
Background technology
Realize big ration, high draft effective spinning, from technological effect, in drafting system, drawing-off parts design, and must reasonably select the problem crucial equipment solving and comes out in existing fine spining machine technique.Back area draft pressure bar is one of key component realizing high efficient technology, and it plays vital effect to the real technique theory realizing " rove big ration, big draft in spinning section ".Existing large nose wheelie is put down the application of leading pressure bar and is substantially met enterprise's need of production, but through a large amount of production practices, its drawback also progressively manifests, and is mainly manifested in: 1, during the two pressure bar of yarn pile warp whole bundle, frictional resistance is large, and then affects yarn Draft Effect; 2, yarn tension adjustment can only be realized after the two pressure bar of yarn pile warp, and it is many to enter the yarn exposed fibers before middle jaw, has influence on spinning yarn quality.
Summary of the invention
Technical problem to be solved in the utility model is to provide the pressure bar that a kind of structure is simple, significantly can improve the spun yarn first break draft zone swiveling wheel of the whole bundle efficiency of yarn.
For solving the problems of the technologies described above, the pressure bar of a kind of spun yarn first break draft of the utility model zone swiveling wheel, comprise pin sub-assembly, the upper pin of described upper pin sub-assembly is staggeredly equipped with downforce rod, upward pressure rod, and described downforce is excellent, upward pressure is excellent is respectively arranged with relative drop center wheel.Middle jaw drawing-off is entered through upward pressure rod drop center wheel top again bottom yarn pile warp downforce rod drop center wheel during the utility model operation, the drop center wheel that the dynamic pressure of yarn band is touched rotates and namely realizes automatic whole Shu Quyu simultaneously, the utility model is to preliminary draft yarn whole bundle in advance, improve the whole Shu Xiaoguo of yarn, efficiency, for production high-quality resultant yarn provides powerful guarantee.In addition, without the need to additional energy in the utility model technique, do not increase enterprise's production cost expenditure.
Further, described downforce rod, the excellent two ends of upward pressure are also respectively arranged with limiting card.During this limiting card operation, spacing the preventing of drop center wheel is come off on corresponding pressure rod.
Further, described downforce rod is movably arranged on below pin front end, and upward pressure rod is movably arranged on above pin stage casing.This setting is beneficial to yarn and imports rapidly, improves whole bundle efficiency.
Further, described drop center wheel downforce rod, upward pressure excellent on can left and right slippage.Yarn to import and while whole bundle, yarn can produce certain traversing along drop center wheel, and the movable drop center wheel arranged can effectively be avoided coming off during yarn traversing, and then improves yarn and import and the stability of whole bundle.
Further, described drop center wheel is set to " U " shape.Through a large amount of production practices of enterprise, flatness, smooth degree when this kind of structure effectively can ensure that yarn imports, for the efficient whole bundle of lower step is laid a solid foundation.
The utility model achieves under the prerequisite not changing former spun yarn back area draft apparatus structure, realizes yarn guide and whole bundle and synchronously carries out, significantly improve the whole bundle efficiency of yarn, produce provide a favorable security for high-quality resultant yarn.
Accompanying drawing explanation
Fig. 1 is the top view of utility model works state;
Fig. 2 is the left view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1 and Figure 2, the pressure bar of a kind of spun yarn first break draft of the utility model zone swiveling wheel, comprise pin sub-assembly 1, the upper pin 2 of described upper pin sub-assembly 1 is staggeredly equipped with downforce rod 3, upward pressure rod 4, and described downforce rod 3, upward pressure rod 4 are respectively arranged with relative drop center wheel 5.
Described downforce rod 3, upward pressure rod 4 two ends are also respectively arranged with limiting card 6.
Described downforce rod 3 is movably arranged on below pin 2 front end, and upward pressure rod 4 is movably arranged on above pin 2 stage casing.
Described drop center wheel 5 can left and right slippage on downforce rod 3, upward pressure rod 4.
Described drop center wheel 5 is set to " U " shape.
The utility model sequentially imports downforce rod 3 at yarn 7, the drop center wheel 5 of upward pressure rod 4 drives corresponding drop center wheel 5 at the uniform velocity to rotate simultaneously, drop center wheel 5 rotates simultaneously to the preliminary whole bundle of the yarn exposed fibers of passing through, jaw drawing-off in the yarn of two whole bundles of drop center wheel 5 imports again, downforce rod 3 of the present utility model, upward pressure rod 4 be arranged in parallel and arrange drop center wheel 5 separately.During actual job yarn 7 some tension pile warp upward pressure rod 4 below the drop center wheel 5 of downforce rod 3 drop center wheel 5 above again import in jaw drawing-off.Yarn just enters lower road draft process with comparatively ideal state after twice whole bundle of drop center wheel 5, significantly improves the effect of the whole Shu Quyu of yarn 7.
During the utility model actual production, enterprise only need be reequiped original spun yarn back area draft pressure bar and can be realized whole beneficial effect of the present utility model, retrofit process only relates to the change of downforce rod 3, upward pressure rod 4 two ends diameters and limiting card 6, does not relate to other structures.
To sum up, the utility model structure is simple, and manufacture, production cost is low and production does not need additional energy, it can significantly improve spinning yarn quality and production efficiency, has low cost, high efficiency double dominant, is suitable for textile enterprise and applies.
