Abstract
The utility model relates to a heavy punch lever combining part on a roving frame. The heavy punch lever combining part on the roving frame comprises a supporting rod, and is characterized in that a supporting seat is arranged on the front face of one end of the supporting rod, the back surface of the other end of the supporting rod is a pressure applying surface contacting a roller, a supporting groove is arranged at one end, close to the supporting seat, of the supporting rod, the supporting groove is arranged in the back surface of the supporting rod, a supporting protrusion is arranged at the position, corresponding to the supporting groove, of the front surface of the supporting rod, and the outer surface of the supporting protrusion is an arc surface. The heavy punch lever combining part on the roving frame is stable in structure, is not easy to loosen, and guarantees stability in the pressurization and drafting process.
Description
Technical field
The utility model relates to a kind of vertical hammer lever, the weight arm conjunction on especially a kind of Speed frames.
Background technology
Speed frames mainly are comprised of feed mechanism, drafter, twisting and winding mechanism and coiling and molding mechanism etc.During Speed frames work, sliver is drawn in the bar cylinder behind machine, is actively carried by conducting bar roller, enters the rear roller jaw through guide strip roller, bar-guiding device etc.Drafter adopts four roller devices, and the fiber in the sliver is subject to drawing-off under the elasticity control of apron, and the yarn after the drawing-off is sent by front roller nip, by the polymerization of collector, is wound up on the bobbin after the twisting of flier again.Rely on the effect of shaping mechanism, make bobbin rail do according to certain rules elevating movement with bobbin, with the tapered flyer bobbin in rove coiled two ends.In twisting and winding mechanism, the twisting winding task of rove is mainly by drape flyer and bobbin routing motion and finishing between the two.
The drafter form of Speed frames is more, and that usually adopts has simple roller draft, curve drawing, needle cycle drawing-off and an apron draft etc.Simple roller draft or curve drawing are applicable to heavier quantitative sliver; The drawing-off ability of needle cycle drawing-off is lower, but a minute comb dissolution is arranged, and generally adopts in hair, silk spinning Speed frames; The drawing-off ability of apron draft is higher, and spinning quality is better, to the wide adaptability of each fibrid.The adding of Speed frames drawing rollers, be pressed with the forms such as weight arm pressurization and Spring cradle pressurization.In the prior art, weight arm generally is arranged on a body of rod of each roller top, and the body of rod is exerted pressure, and makes each to having certain thrust between the roller to realize pressurization and the drawing-off to processed fibrous material.But existing weight arm structure is not very stable, easily produces and becomes flexible, and causes the unstable of pressurization and drafting process.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the conjunction of the weight arm on a kind of Speed frames is provided, and has improved the stability of vertical hammer lever, has guaranteed pressurization and the drawing-off effect of drawing rollers.
According to the technical scheme that the utility model provides, the weight arm conjunction on a kind of Speed frames comprises support bar, it is characterized in that: the front at described support bar one end arranges supporting seat, the exert pressure face of the back side of the support bar other end for contacting with roller; End near supporting seat on described support bar arranges brace groove, and brace groove is arranged on the back side of support bar.
Position in the front of described support bar corresponding to brace groove arranges support protrusion.
The outer surface of described support protrusion is arc surface.
Weight arm Stability Analysis of Structures described in the utility model is not easy to produce and becomes flexible, and has guaranteed the stable of pressurization and drafting process.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top 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 2: as described in weight arm conjunction on the Speed frames comprise supporting seat 1, support bar 2, brace groove 3, support protrusion 4, the face 5 etc. of exerting pressure.
As shown in Figure 1 and Figure 2, the utility model comprises support bar 2, in the front of support bar 2 one ends supporting seat 1 is set, and supporting seat 1 is used for fixed support bar 2, the exert pressure face 5 of the back side of support bar 2 other ends for contacting with roller; End near supporting seat 1 on described support bar 2 arranges brace groove 3, and brace groove 3 is arranged on the back side of support bar 2, and the center of circle of brace groove 3 bottom arc surfaces is the central point that support bar swings; Position in the front of described support bar 2 corresponding to brace groove 3 arranges support protrusion 4, and for the ease of the swing of weight arm, the outer surface of support protrusion 4 is arc surface.
The utility model in use, one end of support bar 2 is installed fixing by supporting seat 1, the other end of support bar 2 is arranged on the drawing rollers, exert pressure to support bar 2, the brace groove 3 on support bar surface below 2 is rotated as the strong point, the counter extensioin roller applies certain thrust, to realize pressurization and the drawing-off to processed fibrous material.Weight arm Stability Analysis of Structures described in the utility model is not easy to produce and becomes flexible, and has guaranteed the stable of pressurization and drafting process.
