Technical field

The utility model relates to a kind of textile machine, refers in particular to a kind of solid compact spinning apparatus that is applied to fine spining machine.

Background technology

In traditional fine spining machine spinning operation, through the sliver of drawing-off with certain width and after leaving front roller under the free state, just be processed to yarn immediately, can form a spinning triangular zone in the formation zone of yarn this moment, because the spinning triangular zone loose fibres can not be by better controlled, thereby the many fibers that make the sliver periphery must head can scatter and can not boundling in advance, the fiber that scatters is stretched out yarn and forms " filoplume " that occurs in the spinning outward owing to not closing lightly in the yarn, have a strong impact on yarn quality, reduced the fiber utilization rate.Therefore, must improve the conveying form of sliver before the twisting, though sliver parallel, stretch, closely arrange.At present, method commonly used is to install aggregate device in drafting unit additional, by at negative-pressure air-flow passage of the front roller output area of fine spining machine design, thereby make sliver by the time because the drive of negative-pressure air-flow makes fiber must hair incorporate sliver into twists together.It as the patent No. a kind of compact spinning apparatus of 03228410.1, be fixed on the air intake duct of being with inlet scoop and exhaust outlet on adjacent two roller stands by being provided with two ends, be enclosed within the cohesion cover that has collection surface on outer and the circumferencial direction of air intake duct corresponding to the position, inlet scoop, be stuck in the tensioning apparatus in the cohesion cover, be enclosed within ventilative conveying circle and transmission pressue device that cohesion puts, this compact spinning apparatus can make the fibre bundle of front roller output under the suction function that exhausting system produces, be adsorbed on ventilative the conveying on the circle, and pressurization transmission device and ventilative the conveying under the effect of enclosing, fibre bundle is tightened up, the state that stretches is realized the twisting resultant yarn, this compact spinning apparatus can solve the problem of original " filoplume " preferably, improve yarn quality, but also come with some shortcomings, as complex structure, production cost is higher; And compact spinning apparatus and roller belong to the different dynamic device respectively and drive, and easily cause compact spinning apparatus speed and roller speed asynchronous, thereby form stifled yarn and broken yarn phenomenon.

Summary of the invention

For addressing the above problem, it is a kind of simple in structure, compact that the purpose of this utility model is to provide, can thoroughly eliminate the triangle spinning district of bottom roll, effectively prevent " filoplume " phenomenon that fine spining machine spinning process occurs, improve the solid compact spinning apparatus of the fine spining machine of yarn quality.

The purpose of this utility model is achieved in that a kind of solid compact spinning apparatus of fine spining machine, it is characterized in that: below the bottom roll of fine spining machine, be installed with yarn guiding rod, have some circle spiral grooves on the yarn guiding rod, the spiral groove cross section is the horn mouth shape, the groove top is wealthy, trench bottom is narrow, and bottom land is semicircular.The bottom land size is different and different according to yam count.During work, after sliver that bottom roll below is spued and the yarn of having twisted link, with connect and yarn that twisting is good on yarn guiding rod around some circles, coiling along with bottom roll action and spinning spindle spurs like this, connect good sliver with twist yarn and turn over some circles around yarn guiding rod, be wound onto on the quill of spinning spindle after leaving yarn guiding rod, finish the Yarn twisting process.In normal operation, the spiral grooves that the sliver that comes out from bottom roll enters yarn guiding rod, the spiral groove cross section is the horn mouth shape, the groove top is wealthy, and trench bottom is narrow, and sliver is by the narrow bottom boundling of groove, thereby the fiber that will stretch out the sliver outside is closed lightly in the sliver, and after moving some circles around narrow channel bottom, when fast disengaging yarn guiding rod, at this moment sliver is twisted under the effect that spinning spindle rotates.So sliver comes out from bottom roll, to this stage of yarn guiding rod be the free zone; From entering the yarn guiding rod spiral grooves, up to leaving the helicla flute end, this stage is a cluster area; In a single day sliver leaves the spiral grooves bottom land, because the sliver that loses tension is to spiral fluted pressure, sliver is twisted because of rotation by spinning spindle, and this stage is a twisting area.

Like this, sliver through the free zone after, in cluster area, under the pressure effect at the bottom of the spiral grooves and between the sliver compacted after, can be with parallel, stretch, state passes through cluster area closely, enter twisting area, under the effect of spindle, twist into yarn, thereby improved the conveying form of fiber before the twisting effectively, effectively eliminated the trigonum in original bottom roll exit, and, improved yarn quality through preventing the generation of " filoplume " in the yarn forming process behind the cluster area, and the action of package unit is carried out synchronously with the action of bottom roll and the coiling effect of spindle, has avoided the generation of stifled yarn and broken yarn phenomenon.

Below in conjunction with drawings and Examples the utility model is further described:
