Abstract
The invention discloses a double roller drafting device. After passing through a rear nip from a bell mouth, a roving yarn (8) is absorbed onto a grid ring by negative pressure air current. When the roving yarn (8) attached on the grid ring (9) moves forward, the outwardly-expanded long fibers are concentrated around the roving yarn (8) by the negative pressure air current. With the forward movement of the grid ring(9), the roving yarn (8) passes through an elastic nip formed by a rear pressure bar (4) and the grid ring (9) to a front nip and is drafted by the front nip. Since the front pressure bar (2) presses the floating area of fiber strands, the quality of obtained yarns is good in evenness and less in hairiness.
Description
Technical field
The present invention relates to a kind of ring throstle, particularly the drafting system on the fine spining machine.
Background technology
Present existing drafting assembly of spinning frame all is three rollers, apron drafting arrangement up and down.Their shortcoming is: the reel cage pressure that needs is big, power consumption is high.That the arrangement drawing-off of and back zone wide by the trigonum and the bar that causes are done is uneven, Yarn filoplume is many, flyings are many, the spinning cost height.
Summary of the invention
Because the deficiency of above-mentioned technology, the present invention takes measures to be: two-roller drafting device before and after adopting.Be provided with a negative pressure pipe (11) between front and back two rollers (13), (7), negative pressure pipe (11) communicates with negative-pressure air fan by pipeline.Be provided with 4-8 and gather groove (14) on negative pressure pipe (11), the first half that gathers groove (14) is made up of many apertures, and the latter half that gathers groove (14) is a wide preceding narrow slotted opening after; On negative pressure pipe (11), also be provided with a chase (12).It is all perpendicular with chase (12) that each gathers groove (14).Grid ring (9) is enclosed within on negative pressure pipe (11), rear roller (7) and the tension bracket (10), grid ring (9) by tension bracket (10) tensioning after and cover and gather groove (14).On two rollers (13), (7), front leather roller (1) was formed preceding jaw with front roller (13) before and after front and back two rollers (1), (6) were pressed in respectively, and back roller (6) and rear roller (7) are formed the back jaw.Last pin (5) is contained on the back roller (6), and the spacing block (3) of two pressure bars (2), (4) is stuck on the pin (5) before and after having.Because Pneuamtic cradle is different with the structure of Spring cradle, so having designed two kinds, the present invention goes up pin, a kind of pin of going up with spring is used on the Spring cradle; A kind of the pin with going up of spring is used on the Pneuamtic cradle.Back pressure bar (4) on the spacing block (3) is pressed in rove in the chase (12) on the negative pressure pipe (11), and forms elastic nip with grid ring (9); Preceding pressure bar (2) on the spacing block (3) is pushed down from negative pressure pipe (11) to the yarn the preceding jaw.In order to prevent that grid ring (9) from skidding on rear roller (7), the fine plastic substance of one deck carbon is arranged on the rear roller (7) of the present invention's design and anti-skid design is arranged.
The invention has the beneficial effects as follows: on existing drafting system basis, deduct a roller, roller, apron etc. up and down, reduced electricity consumption, reduced cost, improved the yarn evenness quality, reduced filoplume.

Among the figure, front leather roller (1), preceding pressure bar (2), spacing block (3), back pressure bar (4), go up pin (5), back roller (6), rear roller (7), rove (8), grid ring (9), tension bracket (10), negative pressure pipe (11), chase (12), front roller (13), gather groove (14).
The specific embodiment
Rove (8) pass horn mouth by the back jaw after, just inhaled on grid ring (9) by negative-pressure air-flow, rove (8) is attached to that flared long fiber just is collected at rove (8) on every side by negative-pressure air-flow when travelling forward on the grid ring (9).Along with passing back pressure bar (4), the rove that travels forward (8) of grid ring (9) forms elastic nip, jaw and by preceding jaw drawing-off before arriving with grid ring (9).Again since preceding pressure bar (2) so pushed down that the quality bar of the district's resultant yarn that swims of yarn makes a good job of, filoplume is few.
