Abstract

The utility model discloses an inverted tube weft unwinding device which is characterized in that: a hook is arranged on a conical rod; the hook is hung on a weft frame; the conical rod with the taper being 0.2 degree to 1 degree smaller than that of the inner hole of a weft tube and the length being 0.5cm to 1cm shorter than that of the weft tube is inserted into an inverted tube weft paper conical pipe; a bolt is mounted in a screw hole on the lower end of the conical rod; tube wefts are fixed on the conical rod; a weft folding porcelain seat is arranged on a weft support plate and is 10cm to 15cm away from the centerline of the tube wefts; the weft folding porcelain seat is 160cm high and 2cm to 5cm wide; a weft folding hole on the weft folding porcelain seat is 15cm high from the support plate; the wefts which pass through the weft folding hole and a weft leading hole form angles being 45 degrees to 60 degrees with the centerline of the tube wefts; and the wefts which pass through the weft folding hole and the weft leading hole are sent into a weft storage device.

Description

Inversion type tube weft yarn take-off device

Technical field

The utility model relates to a kind of spinning take-off device, specifically a kind of rapier loom inversion type tube weft yarn take-off device.

Background technology

In existing rapier loom weft yarn unwinding technology, the mode that the unwinding of rapier loom weft yarn is adopted is: up vertical unwinding formula, and its scheme of installation is seen Fig. 2; Technological process is: the tube weft yarn is placed on the tube yarn supporting plate of storage latitude frame, along with the rotation of weft accumulator, weft yarn is via drawing the yarn hole on the weft yarn creel; Get on the weft accumulator, when the unwinding yarn linear velocity reached 250-270M/mi, friction came off when the short fiber latitude process on the yarn was drawn the yarn porcelain eye; The short fiber latitude falls and is accumulated in a top layer, yarn top, along with increasing of short fiber heaped on the top layer, under certain damp condition; Be very easy to twine with the yarn of high-speed unwinding; The yarn defect is brought in the weft yarn, formed the cloth cover zonal fault, have a strong impact on the quality and the economic benefit of enterprises of finished fabric.

Summary of the invention

The purpose of the utility model is in order to overcome in the existing rapier loom weft yarn unwinding technology; Be prone to during the up unwinding of tube weft yarn twine, the yarn defect is brought in the weft yarn, formation cloth cover zonal fault with the chopped fiber that falls; Seriously influence the quality of cloth cover, a kind of inversion type tube weft yarn take-off device is provided; This device can overcome the existing rapier loom weft yarn unwinding and the problem that the chopped fiber generation is twined and the yarn defect is brought weft yarn into of falling, and has effectively promoted fabric quality, has improved economic benefit of enterprises.

The technical scheme of the utility model is: a kind of inversion type tube weft yarn take-off device comprises the weft yarn frame, links up with, draws yarn porcelain piece, tapered rod, tube weft yarn, taper pipe, bolt, holder yarn plate, draws yarn hole, the yarn porcelain seat of turning back; It is characterized in that: hook is housed on the tapered rod, is mounted on the weft yarn frame, less than spool hole taper 0.2-1 degree; The tapered rod that is shorter in length than spool 0.5-1 centimetre is inserted in the inverted tube weft yarn papery taper pipe; In the screw of tapered rod lower end, the tube weft yarn is fixed on the tapered rod on the bolt, the yarn porcelain seat of turning back is contained on the holder yarn plate; Apart from tube line of centers 10-15 centimetre of weft yarn; The yarn porcelain seat of turning back highly is 160 centimetres, and width 2-5 centimetre, the folding yarn pitch-row supporting plate that yarn is turned back on the porcelain seat is high 15 centimetres; Penetrate in the broken line hole and draw that yarn is a 45-60 degree angle with a tube weft yarn line of centers in yarn the hole in, and then penetrate drawing drawing in the yarn hole on the yarn porcelain piece of adorning on the weft yarn frame, the yarn that penetrates the broken line hole and draw in the yarn hole is sent into weft accumulator.

The beneficial effect of the utility model is: inversion type tube weft yarn take-off device; The inversion of conical tube weft yarn is sleeved on the tapered rod; Make on tin weft yarn suspension weft yarn frame, yarn draws the yarn hole to deliver to weft accumulator for use through drawing behind folding yarn hole on the porcelain seat of turning back in the production run on the yarn porcelain piece.Stop the unwinding of rapier loom weft yarn and the problem that the chopped fiber generation is twined and the yarn defect is brought weft yarn into of falling, effectively promoted fabric quality, improved economic benefit of enterprises.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Fig. 1 is the scheme of installation of the utility model

Fig. 2 is the up vertical unwinding scheme drawing of rapier loom weft yarn of the prior art

1. weft yarn framves in the drawings, 2. hook, 3. tapered rod, 4 screws, 5. bolt 6. draws the yarn hole, folding yarn hole, 7. holder yarn plate, a 8. weft yarn, 9. taper pipe, 10, the porcelain piece, the 11. yarns porcelain seat of turning back, 12, yarn, 13.

The specific embodiment

In the embodiment of the up vertical unwinding device of Fig. 2 rapier loom weft yarn of the prior art, tapered drum yarn 4 is contained on the storage latitude frame supporting plate 6, because the microcephaly of tapered drum yarn is last; Weft yarn is via drawing yarn hole 3 to weft accumulator on the creel 2, and when the unwinding yarn linear velocity reached 250-270M/mi, the friction when drawing the yarn porcelain eye of thread segment chopped fiber came off; Fall and accumulate in a yarn top; Along with assembling increasing of short fiber, under certain damp condition, be very easy to twine with the yarn of high-speed unwinding; Form the yarn defect and bring in the weft yarn, form the cloth cover zonal fault.

In the embodiment of Fig. 1 the utility model; Hook 2 is housed on the tapered rod 3; Metal hanger 2 is mounted on the weft yarn frame 1; Tapered rod 3 is inserted in the papery conic bobbin 9 at inverted tube weft yarn 8 centers, in the screw 4 of tapered rod 3 lower ends, tube weft yarn 8 is fixed on the tapered rod 3 on the bolt 5 to become one.The yarn porcelain seat 11 of turning back is housed on the holder yarn plate 7; The yarn 12 of tube on the weft yarn 8 penetrates yarn and turns back in the folding yarn hole 6 on the porcelain seat 11; Penetrate the yarn 12 in the folding yarn hole 6, penetrate drawing drawing in the yarn hole 10 on the yarn porcelain piece of adorning on the weft yarn frame 1 again, it is for use to deliver to weft accumulator then; Arrow is that yarn is sent into (direction) storage weft yarn device among the figure.Assemble in folding yarn hole for stopping chopped fiber, twine with the unwinding yarn, the folding yarn hole that yarn is turned back on the porcelain seat is located at apart from high 15 centimeters of supporting plate, and the bottom surface of tube weft yarn 8 is 50-70 centimetre apart from holding in the palm yarn plate 7, has thoroughly solved the yarn defect that forms because of winding.

Papery conic bobbin 9 is the used spool of rapier loom in the prior art; The tapering of tapered rod 3 is less than spool hole taper 0.2-1 degree; Tapered rod 3 be shorter in length than spool 5-10 millimeter so that the spool of a weft yarn is tightened together; The yarn porcelain seat of turning back is contained on the holder yarn plate 7 apart from line of centers 10-15 centimetre of tube weft yarn 8; The yarn porcelain seat of turning back highly is made as 160 centimetres; Width 2-5 centimetre; The folding yarn hole 6 that yarn is turned back on the porcelain seat is high 15 centimetres apart from supporting plate, in the broken line hole, is 45-60 degree angle with the yarn that draws the yarn hole with a tube weft yarn line of centers.
