Description

The napping machine of towel rapier loom

The utility model relates to a kind of movable reed napping machine that the weaving towel cloth is used on Rapier looms in the textile industry.

The weaving towel cloth has two kinds of methods on Rapier looms at present, the one, adopt cloth beam to move forward and backward the method fluffing, temple device, temple bar, the back rest etc. all will be made same moved further, it is very complicated and huge that whole like this napping machine just seems, and part is many, cost is high, poor practicability, efficient are also lower; Another kind method adopts by sprocket wheel through the secondary strap moving cam of bevel gear, and the shadoof cover that is packed under action of cam on the fork drives the shadoof fluffing that moves up and down respectively by transmission, and this method structure is complexity, the processing request height, and cost is also just higher.

The purpose of this utility model designs for the deficiency that solves above-mentioned napping machine.

The napping machine (seeing accompanying drawing) of the utility model design by cam, mouth hit, hit sub-arm collision block, hit sub-arm push rod, DC electromagnet, spring, reed etc. and form, its characteristics are that it comprises control section and operating part two large divisions.The architectural feature of control section is: fluffing is hit son and is fixed on and hits on the stroma, and DC electromagnet is packed on the frame, and stage clip is equipped with in the electromagnet upper end, and the other end of stage clip is connected with the control arm of electromagnet, and the other end of control arm contacts mouth hit; The loop-pile controlling cam that is contained on the shedding cam axle contacts with driven rotor in the swing arm, and the other end of swing arm is connected with axle, also is fixed with on the axle to be with trochantinian control arm, and lesser trochanter also contacts with mouth hit.The architectural feature of operating part is: hit sub-arm and be packed on the lay sword by the axle center, the one end is equipped with collision block, the other end links to each other with push rod, the other end of push rod links to each other with pivoted arm, and pivoted arm is contained on the reed folder axle, and extension spring one end links to each other with the extension spring arm, the other end is contained on the lay sword, several reed jig arm of reed also are packed on the reed folder axle, and mouth hit one end is contained on the reed folder axle, and the other end contacts with compressing tablet on being contained in brest beams.In the course of action, sub-arm collision block is hit in the fluffing mouth hit, makes to hit sub-arm rotation and make push rod do upwards to promote to drive pivoted arm to swing, and makes reed do swing.Moving up and down by the camming movement commander who is packed on the opening shedding cam of fluffing mouth hit finished the action that three latitudes one bump or four latitudes one bump, and generates looped pile.The length of towel part and plain weave part is implemented by the DC electromagnet that is subjected to computer control.

The utlity model has following advantage:

1. it is highly stable to fluff, and can not produce the ladder looped pile;

2. the power of beating up is big, can not produce weft crackiness;

3. simple and reliable for structure, do not change traditional method of operating and weaving process;

4. the length of the total length of towel and fluffing part is all controlled by computer;

5. can change fluffing or phozy mode at any time;

6. can reduce power consumption.

Accompanying drawing 1 is the side view of the reed swing mechanism (being operating part) of the napping machine that the utility model proposes,

Accompanying drawing 2 is the side view of control section of the present utility model.

The numbering of each parts of contrast accompanying drawing is as follows:

1. lay sword 2. rockers 3. fluffing mouth hits

4. sub-arm 6. collision blocks are hit in axle center 5.

7. push rod 8. pivoted arms 9. reeds press from both sides axle

10. reed jig arm 11. reed 12. extension spring arms

13. extension spring 14. mouth hits 15. springs

16. cam 17. driven rotors 18. swing arms

19. axle 20. control arms 21. rotors

22. electromagnet stand-off 23. DC electromagnets 24. magnet control arms

25. stage clip 26. slays

Below in conjunction with accompanying drawing the utility model is further described.

When lay sword 1 during around rocker 2 swing, fluffing mouth hit 3 bump kinks are at the collision block 6 on the sub-arm 5 of hitting on the axle center 4, make and hit sub-arm 5 rotating certain angle, push rod 7 is upwards promoted, and the pivoted arm 8 that is packed on the reed folder axle 9 is swung, thereby make 10 swings of reed jig arm, drive reed 11 and do swing as required.Extension spring arm 12 also is packed on the reed folder axle 9, is hauled by two extension springs 13, reed 11 is abutted against on the slay 26, and keep certain power of beating up with this.In order to increase the power of beating up, the mouth hit 14 that is contained on the reed folder axle 9 is compacted when preceding giving up the idea the position, does not make reed 11 loosening.The afterbody of fluffing mouth hit 3 has been equipped with the spring 15 of absorbing effect, to guarantee the reliability and stability of fluffing mouth hit 3 motions.

Be packed in 1/2 or 1/3 cam 16 on the opening shedding cam, rotate with the rotation of opening shedding cam, under the effect of driven rotor 17, swing arm 18 swings.Control arm 20 also just rotates around axle 19, moves up and down thereby the rotor 21 that is contained on the control arm 20 is close to, and commander's fluffing mouth hit 3 moves up and down, and finishes the action that three latitudes one bump or four latitudes one bump.

Be contained in the adhesive and the release of the DC electromagnet 23 on the electromagnet stand-off 22, magnet control arm 24 is moved up and down, and by 25 return actions of stage clip.

When the weaving looped pile, fluffing mouth hit 3 is not controlled in electromagnet 23 adhesives and make magnet control arm 24 downward, finishes the fluffing action and control fluffing mouth hit 3 by control arm 20.

When electromagnet discharges, fluffing mouth hit 3 is raised, no longer bump against i.e. weaving plain weave with collision block 6.

The adhesive of inhaling iron with discharge by the computer control of sync signal being arranged with loom, play long, the fluffing of meter, meter is long to be knitted plain weave and closely effect such as knits.
