Abstract
The utility model is to carried out via the utility model, the coiling length of the safety yarn can be raised, the weft thread waste is reduced, the work efficiency is raised, and the workmen's worform the shuttle loom into the loom with flexible rapiers. The utility model is characterized in that a suit of compensation mechanism formed by an eccentric shaft, a link, a circular arc shape sliding slot and tooth blocks is arranged in the weft insertion system. The utility model has advantages of simple structure, easy regulation and stable and stable reliable working of the weft insertion system. The mechanisms, such as the wallboard, the opening, the weft beating device, the warp sending device, the coiling device, etc. of the old machine are fundamentally not changed. The rotary speed of the reformed loom with flexible rapiers can be raised by 25% than the corresponding old machine, and the noise of the complete machine can be lowered by 15-20 decibels.
Description
The utility model relates to and transform existing fly-shuttle loom as flexible rapier loom, it is characterized in that weft insertion system has adopted four connecting rods of old machine to beat up, the structure of the synthetic transmission wefting insertion sword belt of forming with eccentric shaft, connecting rod, circular arc type chute, tooth piece of compensation mechanism.
At present domesticly weave production and mainly still use fly-shuttle loom, large in number and widely distributed, but its productivity ratio is low, noise is big, machine material consumption is big, and fabric quality is difficult to improve, and the leeway of continuing development is seldom arranged, and the trend that is replaced by shuttleless loom is arranged.According to domestic concrete condition, preferably fly-shuttle loom is transformed.In shuttleless loom, Rapier looms relatively is suitable for improving old machine.
1986, on the ITMA of Guangzhou, Czech put on display a kind of similar domestic 1515 type looms through improved KOVO-200 type flexible rapier loom.The rapier transmission mechanism schematic diagram of weft insertion system as shown in Figure 1.O wherein
1Be crankshaft center, gear Z is arranged on it
1, O
2Be the axis center, gear Z is arranged on it
2, Z
1With Z
2The number of teeth is identical.O
3Be the rocker center, 1 is the crank that beats up, and 2 for leading along by hand, and 3 is lay sword, and 4 for passing the sword crank, and 5 is connecting rod, and 6 is sector gear (Z
3).The center of sector gear 6 is O
4Therefore, beat up the swing of the swing of lay sword and sector gear through gear 7(Z
4) spread out of the reciprocating motion of transmission wefting insertion sword belt after synthetic.The subject matter of this kind of drive is:
(1) the gear Z on the bent axle
1With the gear Z on the axis
2Gear ratio be 1, be not suitable for the transformation of domestic old machine;
(2) because the swing of lay sword is identical with the hunting period of sector gear, the biography sword motion that is synthesized into by them makes the sword head big from the idle running of fell, so the floor space of machine is big;
(3) dynamics of sector gear is poor, causes rocker stressed excessive, causes the fracture of wallboard or rocker stand-off easily.
Domestic 1511,1515 fly-shuttle looms are transform as the existing patent application of flexible rapier loom, its rapier transmission mechanism adopts crank, tooth bar to form.The 1515K fly-shuttle loom transform flexible rapier loom as, and its rapier transmission mechanism is to adopt crank, connecting rod, dihedral bar and tooth bar to form, and is all different with the utility model.
The purpose of this utility model provides and a kind ofly transform fly-shuttle loom as by the sword belt wefting insertion flexible rapier loom, to improve the overall efficiency and the fabric quality of loom, reduces noise.
Accompanying drawing of the present utility model has:
Fig. 1 is the rapier transmission mechanism schematic diagram of KOVO-200 type;
Fig. 2 is a rapier transmission mechanism schematic diagram of the present utility model.
Fig. 3 is that the A of Fig. 2 is to view.
O among Fig. 21Be the bent axle center, gear Z is housed on the bent axle1 Eccentric shaft 4, connecting rod 5, arc chute 11 and tooth piece 6(Z3) forming the compensation mechanism of weft insertion system, tooth piece 6 is in arc chute. Be fixedly mounted with gear Z ' on the eccentric shaft 4, Z ' is by Z on the bent axle on the eccentric shaft1Transmission. O2Be the axis center, gear Z is housed on the axis2, it is by Z1Transmission. 2 for leading along by hand, and 3 is slay, O3Be the rocker center, arc chute center and rocker center superposition. The motion of the swing of lay sword and tooth piece 6 is by gear 7(Z4) synthetic by gear 8(Z5）、9（Z
6) transmission wefting insertion sword belt wheel 10(sees Fig. 3), drive sword belt and move back and forth.
Technical characterstic of the present utility model is a kind of fly-shuttle loom to be transformed into flexible rapier loom, it comprises wefting insertion, beat up, opening, the warp let-off, mechanism such as batch, and it is characterized in that the compensation mechanism of being made up of eccentric shaft, connecting rod, circular arc type chute, tooth piece a cover in the weft insertion system.Its rocker center of improved flexible rapier loom is identical with old machine.Its feature also is circular arc type chute and frame concrete mutually, and its center of arc overlaps with the rocker center.The tooth piece is engaged in the circular arc type chute.Eccentric shaft is by the gear Z on the bent axle
1Transmission, Z
1' be consolidated Z with eccentric shaft
1With Z
1' gearratio be 1:2.The number of teeth of circular arc type chute internal tooth piece is according to old machine reed width, sword head traverse and locations of structures decision.The eccentric distance e of eccentric shaft is selected rational sword head idle running according to the space size that is allowed, and takes all factors into consideration and pass sword system dynamics characteristic and decide.
Bent axle 1 is to the transmission of eccentric shaft 4 employing 1:2 in the utility model, and the big I of regulating eccentric e is regulated the size of sword head idle running effectively, makes the complete machine floor space meet the requirement of improving old machine; Circular arc type chute and frame are directly fixed, and the structure of tooth piece is relatively lighter and handier again, has improved the stressed of rocker, makes the weft insertion system working stability reliable.Transform the comparable corresponding old machine of back loom rotating speed and improve about 25%, total noise of centrifuge can reduce the 15-20 decibel.The utility model is simple in structure, installs, easy to adjust, has at utmost kept the parts of former loom, wallboard, opening, beat up, the warp let-off, mechanism such as to batch constant substantially, is particularly conducive to the work that fly-shuttle loom is transform as flexible rapier loom.
