Abstract
The utility model provides a flexible sword rod loom improved from the existing 1511 and 1515 looms with shuttles. The utility model is characterized in that the flexible sword rod loom uses crank and rack bar transmitting and is suitable for various widths of doors. Adopting the crank and rack bar transmitting, the flexible sword rod loom can basically keep the components of the original loom except a guiding weft; the longitudinal dimension is as width as the longitudinal dimension of the original loom. Because crank and rack bars are transmitting rigidly, the movement from the rack bars and a sword belt is large and the ratio is small; during the movement time the over-passing impulse is small; therefore, the transmitting structure is simple, and the weight is light; the connection between sword heads is reliable, and the flexible sword rod loom has low cost and long lifetime.
Description
The utility model relates to and transform existing 1511,1515 fly-shuttle looms as flexible rapier loom, particularly with the flexible rapier loom of suitable multiple the width of cloth of crank, tooth bar transmission.
At present, domestic textile mills also use fly-shuttle loom in a large number, 1511,1515 use more general.Fly-shuttle loom productivity ratio is low, noise is big, machine material consumption is many, varietal adaptation is poor.Based on this, the flourishing country of some industry is all developing shuttleless loom energetically in the world, and fly-shuttle loom stops to produce basically.So not having shuttle is substituted with shuttle and has become a kind of trend.China has fly-shuttle loom now more than 700,000, therefore, and the efficient ways that it then is a small investment that fly-shuttle loom is transformed, income is big.
Wujiang, Jiangsu two frames are at 1515-75 " designed a flexible rapier loom on the basis; the auxiliary connecting rod mechanism of sword head transmission all is a quadric chain drawing the sword side and connecing the sword side; the crank initial position of regulating in these two quadric chains can make sword head handing-over situation make moderate progress; but its weak point is that former machine change part is more; the rotary inertia of slay and considerable part is bigger; add and adopt short leading along by hand, frame is stressed and vibrate all bigger.
The TP500 flexible rapier loom that Italy Nuove Pignone company produces, the motion of sword head is synthetic by the action of the auxiliary six bar mechanism (or quadric chain) of the swing of slay and a cover, by being installed in the members such as set of gears on the slay, at last motion is passed to the sword head.The curve movement shape of the sword head of this machine is more satisfactory.Because this machine adopts and shortly beats up hand in hand, have the original lay sword of 1511,1515 serial looms etc. now with this mechanism changing so and just can not prolong usefulness, and mechanism's complexity, involve great expense, do not meet the principle of improving old machine.
In the exhibition of the international weaving in Shanghai in 1986 mechanism, a kind of CTR flexible rapier loom of transforming by RVEFT-C type fly-shuttle loom that Italian CINCLA company puts on display, figure ［ 1 ］ is this power traction sword schematic diagram.O among the figure ［ 1 ］

3And then swing together drives cog belt (2) and does corresponding displacement.Corner by wheel (6) will move and transmit out, make the sword head reciprocating at last.Wheel (6) cornerite is mainly worked to increase in wheel (3), (4).Transforming reed width with this is 170 centimetres flexible rapier loom, 270 rev/mins of car scooters.But cog belt was to carry out work under high speed, strong Frotteurism when this mechanism swung at slay, and this just proposes higher requirement to the performance of material.This cog belt life-span is about three months, and at present domestic still do not have this cog belt production, if with this mechanism changing fly-shuttle loom then the production of cog belt be a problem.Simultaneously, this design need increase the lateral dimension of loom to the reed width of broad, and turns round the cog belt elongation of a specified duration and will influence the normal handing-over of sword head.
It is the flexible rapier loom of crank, tooth bar transmission with 1511,1515 weaving loom modifications that the purpose of this utility model provides a kind of, and simultaneously, the utility model has designed a kind of flexible rapier loom that the fly-shuttle loom seriation is transformed that adapts to, and its sword head traverse equation is:
S=11.6 * RS+125(millimeter)
In the formula: RS is nominal reed width (inch)
Pinion number of teeth Z is determined by following formula:
Z=1.9 * 10
4/ S (calculated value rounds up)
In the formula: S is a sword head traverse (millimeter)
The eccentric e value of small crank determines according to different reed widths in the utility model:
When nominal reed width RS=56 inch～75 inches,
E=19 millimeter～23 millimeter.
The flexible rapier loom of crank of the present utility model, tooth bar transmission, kept former machine parts, the motion of its sword head is actually the swing of slay and synthesizing of tooth bar motion, like this, make the motion of sword head after it leaves shed open, long approximate dead time is arranged outside selvedge.Because with crank, this positive drive of tooth bar, become consumable accessory and be durable than the profile of tooth belt length its service life, it has overcome also that cog belt causes elongation after running a period of time and the normal handing-over that influences the sword head simultaneously.After off-centre is set, can make time retardation that the sword head begins to enter shed open a bit, and the time that begins to leave shed open ahead of time a bit, can suitably reduce the extruding of warp thread to the sword head like this.Particularly can not increase the lateral dimension of loom after off-centre is set under the condition of knitting the same cloth width of cloth, it is constant to keep former workshop to arrange like this.
Example of the present utility model elaborates in conjunction with figure ［ 2 ］.Figure ［ 2 ］ draws the sword schematic diagram for the utility model.
Transforming 1511,1515 looms with the flexible rapier loom of crank of the present utility model, tooth bar transmission still adopts four connecting rods of former machine to beat up, only rocker center (D) moved 100 millimeters～200 millimeters behind the machine, like this opening, batch, mechanism such as the warp let-off all can be constant substantially.Drive four connecting rod beating-up mechanism ABCD by crank (3) among the figure ［ 2 ］, wherein BC bar (4) is for leading along by hand.Pinion (8) center E is fixed on the lay sword (5), and gear (2), (1) are with the ratio transmissions small crank (6) of 1:2, and small crank (6) drives tooth bar (7) and makes reciprocally swinging.Tooth bar (7) makes pinion (8) do rotating relative to lay sword (5) with the engagement of pinion (8).Driving sword wheel (11) again after amplify gear (9), (10) does reciprocating linear motion sword head (12).The multiplication factor of traverse is about 8.5 times between from the tooth bar to the sword belt.
By sword head traverse formula S and pinion number of teeth formula Z with 1515 looms be example when the nominal reed width is 56 inches～75 inches its to implement seriation parameter list of transforming as follows:
Nominal reed width (inch) 75 " 67 " 63 " 56 "
The pinion number of teeth 19 21 22 25
Eccentric e(millimeter) 22 22 20 20
The actual maximum denting width of cloth (millimeter) 1,750 1,550 1,450 1270
Sword head traverse (millimeter) 998 903 862 758
Advance 60 ° 67 ° 63 ° 65 ° of shed open time-angles (degree)
Go out 293 ° 288 ° 291 ° 290 ° of shed open time-angles (degree)
Select the improved Rapier looms of above-mentioned parameter for use, lateral dimension is equally wide with original fly-shuttle loom altogether, and its speed of a motor vehicle improves nearly 30% than former machine.
