Description

The compact spinning apparatus of fine spining machine

Technical field

The present invention relates to a kind of textile machine, especially relate to a kind of compact spinning apparatus of 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, block up yarn and broken yarn phenomenon thereby form, and can not eliminate twist triangle zone and influence yarn qualities.

Above-mentioned existing in prior technology defective, the applicant has proposed solution in application number is 200610052980.5 patent application, do not repeat them here.

Summary of the invention

The compact spinning apparatus that the purpose of this invention is to provide " filoplume " problem that occurs in a kind of effective solution fine spining machine spinning process.

The technical solution used in the present invention is as follows; A kind of compact spinning apparatus of spinning frame; Reel cage at spinning frame is equipped with front leather roller; Press on front leather roller the below that front roller is installed in reel cage; The contact area a that forms between front roller and the front leather roller; It is characterized in that: the boundling roller is installed in the front leather roller below; The boundling roller presses on front roller and is synchronized with the movement with front roller; Form contact area c between boundling roller and the bottom roll; The circumferential surface of boundling roller offer some towards the yarn direction of arrival be funnel-form by wide to the narrow boundling tank circuit

The further setting of the present invention is as follows:

The boundling roller can be pressed on the front roller by the seamless unoccupied place of gravity, mechanical prestress or polarity.

The boundling roller is installed on the axle, the boundling roller can pivot, and axle is installed on the front leather roller by a support, and one group of magnet is installed on corresponding front roller on the support, another group magnet is installed on the support corresponding front leather roller, at stent cover the reverse end of front roller and front leather roller is extended to form handle.

Below the present invention is described further by the drawings and specific embodiments.

Description of drawings:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is installed on schematic diagram on the fine spining machine reel cage for the present invention;

Fig. 3 is a kind of embodiment of the present invention;

Fig. 4 is the structural representation of bundling piece of the present invention.

The specific embodiment

As shown in Figure 1 and Figure 2, on the reel cage 1 of fine spining machine, front leather roller 2 is installed, front roller 4 is installed in and is being pressed on below the reel cage 1 on the front leather roller 2, by the contact area a that forms between front roller 4 and the front leather roller 2, between the output a of the drawing-off pressure roller of front roller 4 and front leather roller 2 compositions, constituted draw zone m at the preliminary draft device; Boundling roller 5 is installed in front leather roller 2 belows and presses on front roller 4, forms contact area c between boundling roller 5 and the bottom roll 4.

In conjunction with shown in Figure 4, offer on the circumferential surface of boundling roller 5 some towards yarn 3 direction of arrival be funnel-form by wide to the narrow boundling tank circuit 51, be beneficial to yarn 3 boundlings, boundling roller 5 can pass through gravity, the seamless unoccupied place of mechanical prestress or polarity is pressed on the front roller 4, in the embodiment shown in fig. 3, boundling roller 5 is pressed on the front roller 4 by one group of magnet 9, on the other hand, boundling roller 5 is installed on the axle 7, and can be around axle 7 rotations, the purpose of She Zhiing is like this, when front roller 4 rotations, because the effect of magnet 9, boundling roller 5 is pressed on the front roller 5, under the frictional force effect, boundling roller 5 rotates synchronously with bottom roll 5, in Fig. 3, axle 7 is installed on the front leather roller 2 by a support 6, one group of magnet 9 is installed on the support 6 corresponding 4, one groups of magnet of front roller and is installed on corresponding front leather roller 2 on the support 6, extends to form handle 61 at support 6 in the face of the reverse end of front roller 4 and front leather roller 2.

Operation principle of the present invention is as follows:

During work, pull handle 61, swinging mounting 6 rotates clockwise along front leather roller 2, when rotating certain distance, because the effect of magnet 9, magnet 9 can suck boundling roller 5 on front roller 4, like this, because front roller 4 rotations of fine spining machine, can drive the boundling roller 5 be pressed on the front roller 4 and rotate synchronously, yarn 3 is first drafted in draw zone m, and to enter into contact area c by the output a of draw zone m be in the cluster area, under groove 51 effect of boundling roller 5 by boundling, lead to the gripping point of cluster area c at last, twisted, become spun yarn by the fine spining machine spindle, through holding on the cop of silk point back in going into spindle, finish the technical process of stereo tight spinning again.

When not needing 5 work of boundling roller or maintenance, only need pull handle 61, swinging mounting 6 upwards rotates counterclockwise along front leather roller 2, and when rotating certain distance, because the effect of magnet 8, magnet 8 can be inhaled on reel cage 1.

The present invention compares with original compact spinning, and its advantage is: after adopting the present invention, yarn 3 is after draw zone m drawing-off, directly enter into cluster area c by boundling, twisted by the spinning frame spindle at last, like this, the boundling that is conducive on the one hand yarn 3, the on the other hand easier transmission of the twist. Simultaneously, because the present invention adopts boundling roller 5 and front roller 4 synchronous rotary boundlings, like this, compare with bundle structure in the past, yarn can owing to cause revolution because run into bundling piece, bar not occur and do deterioration, the present invention is simple in structure, and boundling is respond well, and the yarn evenness after the twisting is even.
