Abstract
The invention provides a dysmorphism rod curved line drafting device and is suitable for the field of spins. The dysmorphism rod curved line drafting device comprises a front clamping opening composed by a front roller and a front rubber roller, a middle clamping opening composed by a middle roller and a middle rubber roller, a back clamping opening composed by a back roller and a back rubber roller, a dysmorphism rod, a middle positioning body, a concave and a protruding surface lower pin, a pressure spring, a lower ring and a lower ring tension device. The dysmorphism rod, a middle positioning body, a concave surface and a protruding surface lower pin, a pressure spring, a lower ring and a lower ring tension device are arranged between the front clamping opening and the middle clamping opening. The dysmorphism rod curved line drafting device is characterized in that a convex-concave is arranged on the lower surface of the dysmorphism rod perpendicular to the axis line direction and the convex-concave is arranged in a wave shape. A convex-concave is arranged on the surface of the concave and convex lower pin perpendicular to the axis line direction and the convex-concave is arranged in a wave shape. A curved line drafting passage is formed by the coordination of the protruding and concave part of the dysmorphism rod and the concave and the protruding of the concave and protruding lower pin. Restraining force of a fibre bundle in the middle and the back portion of a main drafting area is strengthened. The length of a floating zone in a front drafting area of a spinning machine is reduced. The dysmorphism rod curved line drafting device is beneficial to the forward displacement, focus and stability of a speed changing of the fibre.
Description
Technical field
The present invention relates to a kind of spinning technique.
Background technology
Adopt two cushion rubber elastic nip drawing-off forms that nearly centenary history is arranged in the ring spinning frame main drawing area.Between the front jaw that exports to front roller and front rubber roll composition of two cushion rubber elastic nips, fiber does not suffer restraints and is commonly referred to the district of swimming, the speed change point that the Qu Yueda that swims, fiber become faster fibres by slow speed fiber moves, does not more concentrate after just, and it is poorer that the bar of resultant yarn is done; The height in two cushion rubber elastic nips exit of using now is more than 10 millimeters, be subjected to front roller, front rubber roll can not stretch forward to the restriction in space, cause that in present fine spining machine front draft zone, fiber does not have the bound district of swimming more than 10 millimeters, affected the further reach of the speed change point of fiber; Too soft due to upper and lower cushion rubber middle part in addition, make the control of main drawing area postmedian fiber very little, this also affected the speed change point of fiber reach, concentrate, stablize.
Summary of the invention
The present invention is used for overcoming the defective of prior art and a kind of length by the district that reduces to swim in the fine spining machine front draft zone is provided, strengthen the control of front draft zone postmedian fiber, reach the speed point reach that is conducive to fiber and becomes, concentrated, stable profile bar curve drafting device.
Address the above problem the technical scheme that adopts as follows:
The objective of the invention is to be achieved by the following measures, a kind of spinning machine profile bar curve drafting device is provided, during consisting of, it comprises the front jaw that front roller and front rubber roll form, the middle jaw that middle roller and middle rubber roll form, the rear jaw that rear roller and back cot form, reaches concavo-convex downside pin, stage clip, Xia Quan and lower circle tensioner at the profile bar between front jaw and middle jaw, interfix body.
profile bar curve drafting device characteristics are: described lower circle is a kind of fabric ring or a kind of cushion rubber, lower snare is at downside pin, on middle roller and tensioner, the lower surface of profile bar is perpendicular to there being convex-concave to be bridge shape or waveform on axis direction, due to the cotton fiber bundle when work require from control rod below by, so the bossing of this profile bar does not contact fibre bundle, recessed portion can be controlled fibre bundle according to technological requirement, the interfix physical efficiency makes and separates a very little distance between concavo-convex downside pin and profile bar and keep at a distance stable, concavo-convex downside pin is solid, concavo-convex downside pin Surface Vertical has concavo-convex bridge shape or the waveform of being on axis direction, profile bar is protruding, concave portion and concavo-convex lower pin surface recessed, protruding mutual corresponding curve drawing passage that forms, lower circle speed with middle roller under the gripping of middle jaw travels forward, tensioner can make lower circle be in all the time tense situation, nervous lower circle and profile bar and concavo-convex downside pin cooperatively interact, gripping the fibre bundle curve travels forward, strengthened the control of front draft zone postmedian fiber, be conducive to the speed change point reach of fiber, concentrate, stable.
Good effect of the present invention is: the forward position radius of curvature of profile bar can do littlely and fully forward jaw stretch, thereby reduce length of floating area in the fine spining machine front draft zone; The speed change point of fiber is moved forward, concentrate, stablize, resultant yarn evenness quality level improves.Also strengthened simultaneously the control of postmedian fiber in the front draft zone, the speed change point that is conducive to fiber further moves forward, concentrates, stablizes; The present invention also can be used in conjunction with multiple compact spinning or compact spinning device easily, becomes Yarn Evenness and filoplume to be further improved.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention;
Fig. 2 is another routine structural representation of the present invention;
Fig. 3 is another routine partial structurtes schematic diagram of the present invention
1. front rubber rolls in figure, 2. front roller, 3. stage clip, 4. profile bar, 5. interfix body, 6. concavo-convex downside pin, 7. tensioner, 8. time circle, 9. in rubber roll, 10. middle roller, 11. back cots, 12. rear rollers, the 13. fibre bundle directions of motion
The specific embodiment
In diagram, lower circle (8) is enclosed within on concavo-convex downside pin (6), middle roller (10) and tensioner (7), interfix body (5) is in the middle part of profile bar (4), interfix body (5) is pressing under the effect of stage clip (3) above concavo-convex downside pin (6), interfix body (5) will separate the curve drawing passage that forms a conveying fiber bundle between profile bar (4) and concavo-convex downside pin (6), so that fibre bundle (13) He Xiaquan (8) passes through.fibre bundle (13) passes through from profile bar (4) lower surface under the holding of Xia Quan (8), stage clip (3) upper end is connected with reel cage, the lower end is connected with interfix body (5), stage clip (3) can lift profile bar (4) or be pressed in above concavo-convex downside pin (6) easily by interfix body (5) according to operative employee's requirement, the pressure energy of stage clip (3) make profile bar (4) in the situation that when work both sides afford respectively lower circle (8) and fibre bundle (13) tension force effect relative position keeps stablizing, thereby make profile bar (4) more stable to fibre bundle (13) control action of front draft zone postmedian.the rear jaw that fibre bundle during work (13) at first forms from rear roller (12) and back cot (11) enters into the first break draft district, pass through again middle roller (10) and enter into the front draft zone with the middle jaw that middle rubber roll (9) forms, because the front draft zone postmedian has profile bar (4), lower circle (8), the control action in concavo-convex downside pin (6) forms curve drawing district, the speed change point of fiber is close and concentrated to the front jaw that front roller (2) and front rubber roll (1) form, be conducive to satisfy the speed change point " reach of fiber, concentrate, stable " the spinning process requirement, resultant yarn evenness quality level will improve.
