Description

The quick warp let-off and creel formula constant tension device

Affiliated technical field

The utility model relates to the quick let-off motion of loom, relates in particular to a kind of quick warp let-off and creel formula constant tension device.

Background technology

At present, popular flexible rapier loom, the filling density scope of its let-off motion is 10～45/CM, warp thread is commonly the looming weaving by warping, and the characteristics of a lot of industrial cloths are requirement pick count rarer (generally between 1～5/CM), package length is longer, this is for the let-off motion through shaft type, the length of its fabric must be subjected to the restriction of its warped length, and original let-off motion, also can't produce for the industrial cloth that filling density is rarer, make some industrial cloths such as checked cloth, grid cloth, it is produced and runs into a lot of difficulties always.

Summary of the invention

Not enough in order to overcome existing loom warp run-in when producing checked cloth, grid cloth, the fabric length package capacity is less, and from the creel directly the warp let-off can't guarantee problems such as its warp tension is even, the utility model provides a kind of quick warp let-off and creel formula constant tension device, this mechanism can not only send warp thread as required with relatively large, and can make warp thread directly pull out and keep the even perseverance of tension force from the creel, make the package length of fabric not be subjected to warped length and limit.

The technical solution adopted in the utility model is in order to achieve the above object: comprise warp-feeding mechanism, constant tension mechanism, the back rest mechanism of loom, wherein:

1) warp-feeding mechanism of loom: comprise the multistart worm that is in transmission connection with let-off motion, the engagement of multistart worm and worm gear drives the warp let-off gear that is contained on the same worm-wheel shaft and rotates, warp let-off gear with through the shaft gear engagement, drive and be contained in rotating on the same axle through beaming roller;

2) constant tension mechanism: an end that is included in the cord roller supporting plate is equipped with fulcrum, fulcrum is connected with loom, the other end and the lifting regulating rod of cord roller supporting plate are hinged, first cord roller that is installed on the supporting plate is housed on the cord roller supporting plate from right to left successively, second cord roller of the cord roller supporting plate that is installed in, the 3rd cord roller, on the cord roller supporting plate between second cord roller and the 3rd cord roller, the dihedral frid is housed, the 4th cord roller two axial ends is installed in the groove of dihedral frid, cam is hinged on the dihedral frid with fulcrum, one end of strut is hinged on the cam, the other end of strut withstands on beaming roller, and the downside of cam is equipped with handle.

The useful effect that the utlity model has is: the quick warp let-off of mechanism can make the filling density of fabric reach between 0.8～10/CM, and the length of fabric take-off is not subjected to the restriction of warped length, and the even perseverance of warp tension has guaranteed that again the fabrics cloth cover that weaves is more solid, straight.This mechanism structure is simple, entrys conveniently.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, it comprises warp-feeding mechanism, constant tension mechanism, the back rest mechanism of loom the utility model, wherein:

1) warp-feeding mechanism of loom: comprise that let-off motion drives to multistart worm 3, through worm gear 2 warp let-off gear that is contained on the same worm-wheel shaft 1 is rotated, warp let-off gear 1 drives through shaft gear 4, and making turns clockwise through beaming roller 6 sends warp thread 15;

2) constant tension mechanism: an end that is included in cord roller supporting plate 13 is connected with loom by fulcrum 12, its other end and lifting regulating rod 21 are hinged, first cord roller 19 that is installed on the supporting plate 23 is housed on the cord roller supporting plate 13 from right to left successively, second cord roller 10 of the cord roller supporting plate 13 that is installed in, the 3rd cord roller 7, on the cord roller supporting plate 13 between second cord roller 10 and the 3rd cord roller 7, dihedral frid 22 is housed, the 4th cord roller 18 two axial ends are installed in the groove of dihedral frid 22, cam 9 is hinged on the dihedral frid 22 through fulcrum 16, one end of strut 8 is hinged on the cam 9, the other end of strut 8 withstands on beaming roller 6, and the downside of cam 9 is equipped with handle 20.

As shown in Figure 1, the let-off motion of former loom drives to four-head worm screw 3, drives worm gear 2, and the warp let-off gear 1 that is contained on the same worm-wheel shaft is rotated, and drives through shaft gear 4, sends warp thread 15 thereby make to turn clockwise through beaming roller 6.Warp thread is drawn from creel 14, enters through beaming roller 6 behind reed 11, the first cord rollers 19, second cord roller 10, the 4th cord roller 18, the 3rd cord roller 7.

When needs are entried by hand, as shown in Figure 3, depress handle 20, around fulcrum 16 turn clockwise for the cam 9 of one with handle 20 welderings this moment, raise the 4th cord roller 18, simultaneously, because of strut 8 one end fulcrums are fixed on the cam 9, when cam clockwise rotates, roller 5 on strut 8 other ends is run into through beaming roller 6 cylindricals becomes fulcrum, and handle 20 continues to press down, because of the effect of roller on the strut 5, whole cord roller supporting plate 13 is rotated counterclockwise around fulcrum 12, when the 4th cord roller 18 fell into cam 9 breach, the 3rd cord roller 7 separated with through beaming roller 6, at this moment, the 4th cord roller 18 also with second cord roller 10, the 3rd cord roller 7 has strengthened the gap, has made things convenient for the cross-under operation of warp thread.After finishing when entrying, handle 20 is upwards cocked, and the 4th cord roller 18 is reset to the origin-location, and mechanism can do the quick warp let-off, and makes the warp thread of sending keep the even perseverance of tension force.

The utility model increases a number and the warp let-off shaft gear number of teeth of former warp let-off worm screw 3, reduce the gearratio of each warp let-off gear, the rotation amplitude that the let-off motion of loom is reflected to through axle has tangible increase, then send with relatively large as required thereby make, to reach the effect of the quick warp let-off around the warp thread on axle.When warp thread is drawn from creel 14, the continuity of yarn tube on the creel has guaranteed that the package length of texture is not subjected to limit because of warped length.And the warp thread that comes out on the creel 14 leads through the S type through 4 cord rollers, introducing is through beaming roller, by sending through beaming roller and enter brown frame opening through the eccentric back rest 17 of eccentric back rest mechanism, owing to be surrounded by the plane rubber through the beaming roller surface, make the warp thread on surface be unlikely to slide, and, the warp thread degree of tightness that enters through beaming roller is regulated evenly in advance automatically through the effect of 4 cord rollers, like this, just can reach even permanent purpose by warp thread through the eccentric back rest 17 its tension force through beaming roller output.When need were entried by hand, as long as handle 20 is pressed down, just amplified naturally in the gap between each roller, and it is very convenient to entry.
