Abstract

The utility model relates to a rapier towel loom, particularly to a fluffing device on the rapier towel loom. The utility model comprises a steel reed which is tightly fixed on a steel sley. The steel sley is installed on a swing arm. The lower end of the swing arm is installed on a pivot base via a rotary shaft, and the middle part of the swing arm penetrates through an eccentric shaft. An eccentric wheel and a pinion are tightly installed on the eccentric shaft, and the pinion is engaged with the swing arm with a tooth-shaped part. The lower end of the swing arm is connected with a connecting rod via a connecting shaft. One end of the connecting rod is connected with a spring, and the other end is hooked on a stop block via a horizontal pin. The utility model has no impact during work, difficult damage of a workpiece, good reliability and stable fluff height. The utility model is an ideal eccentric movable reed device.

Description

The movable reed device of centering type

One, technical field

The utility model relates to a kind of arrow shaft terry cloth loom, relates in particular to the napping machine on a kind of arrow shaft terry cloth loom.

Two, background technology

At present domestic reed formula fluffing mode alive commonly used on the arrow shaft terry cloth loom is the fluffing of bump swing arm, reciprocally swinging along with slay, hit the root of the tongue according to technological requirement on the frame, the swing arm lower end of bump fluff mechanism, by putting behind a series of linkage drive activity reeds, finish the hand-to-hand fight in tights and the long dozen of weft yarn.Have serious bump to produce in the parts work, parts wear and tear easily.And linkage parts chain is longer, and poor rigidity is easy to generate the not first-class problem of terry height during speed car, influence product quality.

Three, summary of the invention

The utility model is at above-mentioned deficiency, and purpose is to provide a kind of component wear little, rational in infrastructure, the movable reed device of the centering type of terry height high conformity.

For achieving the above object, the technical solution of the utility model is: the movable reed device of centering type, comprise reed, the reed seat, lay sword, the slay angle bar, wherein reed is fastened on the reed seat, lay sword and slay angle bar fasten as one, the reed seat is installed in the swing arm, and the swing arm lower end is installed on the axle bed by rotating shaft, and can rotate around axle bed, axle bed then is installed on the lay sword, eccentric shaft is passed at the middle part of swing arm, and eccentric shaft tightens eccentric wheel and pinion are housed, and eccentric wheel is connected with swing arm by eccentric bushing again simultaneously, pinion and drive the rocking arm engagement of tangible tooth on it; is provided with the rocking arm fulcrum in the middle of the rocking arm, the rocking arm lower end has groove, and connecting axle can move up and down in groove and be fixing; connecting axle links to each other with connecting rod; be connected with spring on connecting rod one end, and the other end passes through the lateral pin hook on stops, also is connected with stay cord on the connecting rod.

The utility model structure basic principle be: the revolution of the certain angle by eccentric shaft reaches reed and slay relative swing on the slay angle bar, the fluffing mode that this eccentric shaft drives the slay swing is different from the original bump that passes through makes reed and the slay swing mode with respect to the slay angle bar, the impact shock and the machine members of original impacting type have been avoided fully, and moving parts are few, the good rigidly of mechanism, the reliability height, the noise of loom reduces greatly.

Good effect of the present utility model is: 1, the movable reed napping machine of this centering type does not have impact, and parts are not fragile, good reliability.2, mechanism's good rigidly, terry height is stable, and relevant parameter is regulated easy.

Five, the specific embodiment

As shown in Figure 1, on reed seat 2, the reed seat 2 of aluminum is installed in the swing arm 3 reed 1 by the screw clamping, and swing arm 3 lower ends are installed on the axle bed 7 by rotating shaft 8, and can do a low-angle rotation around axle bed 7.7 of axle beds are installed on the lay sword 9, and lay sword 9 mid portions play strengthens the rigidity effect, and slay angle bar 10 play supporting role, and lay sword 9 fastens as one with slay angle bar 10.Eccentric shaft 4 is passed at the middle part of swing arm 3, eccentric wheel 5 is packed on the eccentric shaft 4 by key pin, eccentric wheel 5 is connected with swing arm 3 by eccentric bushing 6 again simultaneously, pinion 11 is gone up rocking arm 12 engagements that drive tangible tooth 21 with it; be provided with rocking arm fulcrums 13 in the middle of the rocking arm 12; rocking arm 12 lower ends have groove 17, connecting axle 14 can move up and down in groove 17 and fix.Connecting axle 14 links to each other with connecting rod 15, is connected with spring 20 on connecting rod 15 1 ends, and the other end on stops 18, also is connected with stay cord 16 by lateral pin 19 hooks on the connecting rod 15.

Operation principle of the present utility model is: as shown in Figure 2, when reed seat 2 is done two hand-to-hand fights in tights, when lay sword 9 is swung forward, connecting rod 15 is owing to be hooked on the stops 18, pulling rocking arm 12 clockwise rotates around rocking arm fulcrum 13; sector 21 on the rocking arm 12 drives pinion 11 and eccentric shaft 4 rotates 180 °, and at this moment the center of eccentric wheel 5 is forwarded to the right of eccentric shaft 4 by the left side of eccentric shaft 4.Swing arm 3 is 8 swing certain angles around the shaft, and reed 1 is reed fluffing distance in the difference of the variable in distance of fabric on the position line, and this reed fluffing distance is the distance of reed and fell just, and it has determined the size of fabric looped pile.When requiring the long dozen latitude, signal the lifting that dobbies produces by stay cord 16, lateral pin 19 on the connecting rod 15 is separated with stops 18, when lay sword 9 is swung forward, connecting rod 15 is under the effect of spring 20, connecting rod 15 is followed rocking arm 12 swing forward together, and at this moment reed 1 beats weft yarn to fell, finishes the process of once fluffing.

The size (being the size of looped pile) of the angle (being the height of looped pile) of reed seat 2 relative slay angle bar 10 back pendulum can be regulated by the upper-lower position of rocking arm 12 lower end connecting axles 14 in groove 17, on move rocking arm 12 then the amplitude of oscillation increase, transmission by sector 21 and pinion 11, the rotational angle of eccentric wheel 5 is increased, the back amplitude of oscillation degree of reed 1 increases thereupon, terry height increases, and moves down then that the amplitude of oscillation of rocking arm 12 reduces, and terry height reduces.
