Description

Sirospun fiber strip sliver-splitting device

The utility model belongs to field of textiles, is particularly useful for fine spining machine.

In traditional ring spinning is produced, enter rove behind the draw zone through back area draft and proparea drawing-off, before arriving, each the root fiber in the rove has been free state during jaw.Because bigger with the resultant yarn width differences of twisting back spun yarn, at this moment form to distinguish and to form so-called spinning triangular zone at the yarn of front roller nip through the yarn width of drawing-off.At this moment in the formed yarn formation structure, sth. made by twisting widely different (the extexine sth. made by twisting width of cloth maximum that the fiber of ectonexine is suffered, it is zero that heart layer is twisted with the fingers the width of cloth), the fiber of different layers is also very big to the difference of the contribution margin of yarn strength when making resultant yarn, the asynchronism of the inhomogeneous and fibrous fracture of fiber load causes the reduction of yarn strength when causing tension test.

The purpose of this utility model is to provide a kind of sirospun fiber strip sliver-splitting device, to overcome the low shortcoming of yarn strength.

The technical solution of the utility model is achieved in that sirospun fiber strip sliver-splitting device, it comprises by M shape spring steel wire 1, band groove cuts apart the M shape spring carrier that roll shaft deck 2, band triangle pressure block 3 are formed, it is characterized in that also comprising by a pair cut apart roller 4, cut apart roll shaft 5, abutment sleeve 6 is formed cuts apart roller.A pair of cutting apart roller cut apart have on the roller 4 cut apart groove 7 and plush copper 7 ', this pair cut apart roller 4 respectively close-fitting cutting apart roll shaft 5 two ends, and be supported on respectively on front roller 8 surfaces, cut apart the band groove that roll shaft 5 tightly is stuck in M shape spring carrier and cut apart on the roll shaft deck 2, abutment sleeve 6 is fastened on to be cut apart on the roll shaft 5.

Compared with prior art, the utility model has the advantages that: 1, cut apart roller the fiber strip that enters before the twisting area is cut apart, realized by employing

The sirospun technology can improve the uniformity that fiber is twisted with the fingers the width of cloth in the yarn, makes the fiber in the yarn

Contribution to yarn strength improves greatly.The wear resistance of resultant yarn can be equal to mutually with doublet cord

Beautiful.2, this apparatus structure is simple, easy for installation, cost is low, is suitable for existing cotton spinning, hair

Spin, the transformation of bast fibre spinning, silk spinning fine spining machine.

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

Fig. 3 is cut apart the groove enlarged diagram of roller for the utility model

Among Fig. 3,7-is cut apart groove;

Fig. 4 is cut apart the roller lateral sectional view for the utility model

Among Fig. 4,7 '-cut apart the plush copper on the groove;

Fig. 5 is cut apart the trench cross section figure of roller for the utility model

Among Fig. 5, a-is cut apart the land width of groove, and b-is cut apart the concave surface width of groove,

C-is cut apart the concave surface degree of depth of groove.

As shown in figures 1 and 3, sirospun fiber strip segmenting device is installed at front draft zone front roller 8 jaw exits.The diameter that a pair of cutting apart roller is cut apart roller 4 is littler than front roller 8 diameters, is convenient to can hold simultaneously on the front roller 8 front leather roller 9 and cuts apart roller 4.The effect of cutting apart roller is not to affect or the drawn fiber yarn, but fiber strip was cut apart the horizontal equally distributed fiber strip of drawing-off with the acting in conjunction of front roller 8 through the groove of cutting apart on the roller 47 of cutting apart before entering twisting area, make front draft roller 8 and cut apart the fiber strip of exporting at the roller nip place and be the little yarn of multiply, the turn that is sent to the jaw zone by the twisting zone is carried turn (weak twist) respectively to multiply palpulus bar earlier, and (combination of palpulus bar) twists (heavy twist) resultant yarn to whole yarn again.The new design of these two kinds of twisteds makes in the yarn formation structure ectonexine fiber twist with the fingers width of cloth difference obviously to reduce, and fiber is twisted with the fingers the uniformity of the width of cloth when having improved resultant yarn, so the yarn strength of same number can be greatly improved.

As Fig. 3, Fig. 4, shown in Figure 5, it is vertical with the groove direction of front roller 8 to cut apart the direction of cutting apart groove 7 that a pair of roller cuts apart on the roller 4, parallel with the yarn channeling direction.The land width a of cutting apart groove 7 is 0.3～0.5mm, and convex shape can be rectangular, arc or pointed shape, and the concave surface width b of cutting apart groove 7 is 0.3～0.5mm, and concave surface degree of depth c is 0.3～0.5mm, and concave can be rectangular, arc or U-shaped.Convex surface and concave surface are parallel to each other, and its direction is parallel to the direction of motion of yarn.The groove 7 of cutting apart that one pair is cut apart roller 4 can be continuous along cutting apart the circumferential distribution in roller 4 surfaces, also can be interrupted by plush copper, cuts apart groove and is at least one group, and the plush copper that a pair is cut apart on the roller 2 is at least 2.

A pair of cutting apart roller is cut apart roller 4 and is adopted flexible material such as polytetrafluoroethylene (PTFE) to make, and helps the gripping to fiber strip, cuts apart roll shaft 5 and abutment sleeve 6 to adopt steel materials to make, and both form tight fit.

As Fig. 1, shown in Figure 2, lower right side that M shape spring steel wire 1 front and back are two and lower-left side tightly are through the band groove respectively and cut apart roll shaft deck 2 and be with on the triangle pressure block 3, the band groove of M shape spring carrier is cut apart 2 clampings of roll shaft deck and is cut apart roll shaft 5, the front bevel of band triangle pressure block 3 leans against the inner surface of front roller 8, play backer's effect, the upper end pincers of M shape spring carrier are stuck on the front leather roller axle 9 ', M shape spring carrier is last fulcrum with roller axle 9 ', band triangle pressure block 3 is that the roll shaft deck 2 of cutting apart of an end and band groove forms two lower fulcrums for the other end, two lower fulcrums distortion on 8 of front rollers when 10 springs that pressurize by rocking arm press down, make and cut apart roller 4 and be pressed on front roller 8 surfaces, and by abutment sleeve 6 location.During duty, carry out transmission by friction to cutting apart roller 4, to realize to functions such as the cutting apart of fiber strip, guiding by front roller 8.
