Abstract
The roller drafting mechanism includes front roller, front pressure roller, back rollers and s. The back rollers include one first back roller and one second back roller, the back pressure rollers include one first back pressure roller and one second back pressure roller dislocated mutually horizontally in the cotton silver motion direction. There may be two cotton silvers, one passing through between the first back pressure roller and the first back roller, the other passing through between the second back pressure roller and the second back roller, it is possible to control the two back rollers in different rotation speeds to draft cotton silvers in different multiple and to spin two homogeneous or inhomogeneous pieces of yarn.
Description
Technical field
The present invention relates to a kind of sliver drafter of spinning machine.
Background technology
Prior art as shown in Figure 1, before it comprises, in, three rollers in back and three pressure rollers are formed, in process of production, three groups of rollers, pressure roller moves in the same way, and the linear velocity of front roller is greater than the linear velocity of middle roller, the linear velocity of middle roller is greater than the linear velocity of rear roller, the rove bar enters between rear roller and back pressure roller, between middle roller and middle pressure roller, between front roller and the preceding pressure roller, between rear roller and back pressure roller, in the zone between middle roller and the middle pressure roller sliver is carried out preliminary draft, between middle roller and middle pressure roller, carry out the traction of multiple between front roller and the preceding pressure roller and by exporting between front roller and the preceding pressure roller, the purpose of drafter is exactly that thicker rove bar is spun into thinner yarn, but its shortcoming is can only feed one or one group of sliver in the section at one time, if one group of sliver, the drawing-off ratio of this group sliver is identical.
Summary of the invention
The object of the present invention is to provide a kind of rove bar that can feed more than two or two, the drafting multiple of this rove bar more than two or two can be provided with respectively as required.
Technical scheme of the present invention is: a kind of roller drafting mechanism comprises front roller [3], preceding pressure roller [3 '] and rear roller, back pressure roller; It is characterized in that: described rear roller comprises first rear roller that the postero-anterior position installs, second rear roller, the real roller of the first back pressure roller that is provided with before and after described back pressure roller comprises, the real roller of the second back pressure roller, the described first back pressure roller is real, and roller is relative with first rear roller presses, the second back pressure roller is real, and roller is relative with second rear roller presses, the real roller of the described second back pressure roller and the described first back pressure roller reality roller fail to agree the dextroposition setting on the direction of motion of sliver, make the sliver of winning through between the real roller of the first back pressure roller and first rear roller of pressing relatively, second sliver is through between the real roller of the second back pressure roller and second rear roller of pressing relatively.
The present invention compared with prior art has following advantage:
Owing to two slivers can be arranged respectively through between the real roller of the first back pressure roller and first rear roller, between the second back pressure roller reality roller and second rear roller, so the difference that can pass through the rotating speed of control first rear roller, second rear roller realizes the traction to the different multiples of the sliver more than two or two, the rotating speed of two rollers can alternately change, and can be spun into a kind of even or uneven two groups of yarns of thickness.
