Abstract
The utility model relates to a drafting device of a roving machine capable of enhancing control of floating fibers, which solves the problem of control of floating fibers. In the technical scheme, the drafting device comprises four pairs of rollers arranged in sequence. In the improved structure, a pressure rod component is arranged between a third roller and a fourth roller and comprises two brackets, two adjusting slide blocks and a pressure rod, the two brackets are arranged to be opposite to each other, the two adjusting slide blocks are respectively arranged on the two brackets, and the pressure rod is fixedly arranged on the two adjusting slide blocks. Since the pressure rod component with the bunching function is arranged between the third roller and the fourth roller, the novel friction field can be added for moving fibers, thereby enhancing the control of the moving fibers, and the bunching structure on the pressure rod has a certain narrowing function for fibers drafted within a small scale, so that all the fibers can be fed into the third roller, thereby making full preparation for intense high-power drafting in next step.
Description
Technical field
The utility model relates to a kind of textile machine, strengthens the bobbiner drafting assembly to floating fiber control specifically, belongs to technical field of textile machine.
Background technology
Bobbiner drafting assembly comprises four pairs of rollers that set gradually, sell on the elastic nip of bobbiner drafting assembly technology comparative maturity at present mainly in order to control main drawing area yarn, i.e. motor fiber between second roller and the 3rd roller, because pin and the formed elastic nip of last cushion rubber can be relatively near second roller nips on the elasticity, no control zone is very short, be approximately between the 5-15mm, so can strengthen control floating fiber.Comparatively speaking, the noncontrolled area, drawing-off back zone of drafting system is longer, be approximately 10-30mm, like this by the sliver of the 4th roller feeding when the drawing-off through too small multiple arrives the 3rd roller, the fiber of length distance motion is owing to the effect that only is subjected to roller two ends drawing-off gravitation has increased the uncertainty that floating fiber moves, and then the bar of initiation product is done inhomogeneous.So be necessary that reinforcement, is laid a good foundation thereby do value for the bar that improves rove and spun yarn for next step main drawing-off is got ready to the control of motor fiber in long zone, Speed frames drawing-off back zone.
Summary of the invention
The utility model is used to overcome the defective of prior art and a kind of bobbiner drafting assembly to floating fiber control strengthened that increases a friction field in the drawing-off back zone and fiber is had collecting action is provided.
It is as follows to address the above problem the technical scheme that is adopted:
A kind of bobbiner drafting assembly of strengthening floating fiber control, it comprises four pairs of rollers that set gradually, its special feature is: be provided with the pressure bar assembly between described the 3rd roller, the 4th roller, described pressure bar assembly comprises two stands, two adjustment slide block and pressure bars, described two stands is provided with in opposite directions, two adjust slide block lays respectively on the two stands, and described pressure bar is fixed on two and adjusts on the slide block.
The above-mentioned bobbiner drafting assembly of strengthening floating fiber control, described pressure bar bottom is provided with bundle structure, described bundle structure is a dovetail groove, the slot of groove and wide mouthful of respectively corresponding the 3rd, the 4th roller, wherein, slot size b is the 12-18 millimeter, and wide mouthful of size b is the 20-30 millimeter, and groove depth size h is between the 1/4-1/2 of pressure bar diameter.
The above-mentioned bobbiner drafting assembly of strengthening floating fiber control, described support top is provided with chute, and described adjustment slider bottom is embedded in the chute, adjusts slide block and support and is fixed by trip bolt.
The above-mentioned bobbiner drafting assembly of strengthening floating fiber control, described adjustment slide block top is provided with the round short slot with pressure bar end size coupling.
The utility model is longer at noncontrolled area, existing bobbiner drafting assembly drawing-off back zone, floating fiber controlled degree problem of smaller is improved, in drawing-off back zone the 3rd, pressure bar assembly with boundling effect is set between the 4th roller, described pressure bar assembly increases a new friction field not only can for the fiber of motion, reinforcement is to the control of motor fiber, and the bundle structure that is arranged on the pressure bar can have certain effect that narrows to the fiber after the small size drawing-off, make them concentrate feeding the 3rd roller, for next step more violent high drafting is carried out adequate preparation.The utility model is used for Speed frames, not only can reduce rove and spun yarn bar and do value, spun yarn details, slubbing and cotton knot is had significantly descend, and yarn quality is improved a lot.

The specific embodiment
Referring to Fig. 1, the utility model comprises front roller 1, second roller 2, the 3rd roller 3, the 4th roller 4 that sets gradually in constituting, the longer problem in noncontrolled area, drawing-off back zone in view of the 3rd roller 3, the 4th roller 4, between the 3rd roller, the 4th roller, the pressure bar assembly is set, wherein, pressure bar 5 is pressed in sliver 10 tops, gives additional new friction field of motor fiber of drawing-off back zone, so that the floating fiber in the better controlled motion.
Referring to Fig. 2-4, described pressure bar assembly comprises two supports 7, two adjustment slide block 8 and pressure bars 5, described two stands is provided with in opposite directions, be separately fixed on the 3rd roller shaft bearing 6, support top is provided with chute 7-1, the chute place is provided with the flute profile screw hole, adjusts slider bottom and is embedded in the chute, and it is fixing by trip bolt 9 to adjust slide block and support.This design can realize the fine setting of pressure bar position by regulating the position of adjusting the relative chute of slide block.For adapting to the spinning action need, pressure bar should be able to be dismantled fast, easily, be provided with the round short slot 8-1 that mates with the pressure bar end size on adjustment slide block top, the pressure bar end is installed in this groove, the circular arc that the circle short slot is contained is greater than semi arch, like this, rely on the notch strain to be pressed into easily or to take out in the time of can making the pressure bar dismounting, can bear certain pressure in the time of can guaranteeing pressure bar work again.
