To plain cloth, up warp thread equates with descending warp thread quantity, when warp thread moves to comprehensive mean place (warp thread remain silent or broaching tool contour), the return spring 4 that up broaching tool and descending broaching tool are lifted ' deflection and return comprehensive power and equate that also the load on lifting rocking bar 1 ' both sides is in poised state (not considering beveled).After comprehensive the putting down, along with the rising of up broaching tool, corresponding return spring 4 ' further elongate return spring 4 when maximum open ' distortion and pulling force maximum; Descending broaching tool then is in lowest order, pairing return spring 4 ' distortion and time comprehensive power minimum, the only remaining minimum that can spur Warp opening is returned comprehensive power, at this moment, the ratio of the loading moment on lifting rocking bar 1 ' both sides is about 10: 1-8: 1, and shedding mechanism required driving torque maximum; After exceeding the maximum a little, high-order broaching tool is under the synergy of this unbalanced load and mechanism's driving force, almost undamped decline, combine mean place up to the next one, to produce powerful impact and noise therebetween, become electronic jacquard machine and can not get the hard nut to crack that solves for a long time, therefore industry standard makes strict assessment noise as the mandatory index of measurement electronic jacquard machine quality good or not.
A kind of scheme was once arranged in the industry, promptly on broaching tool frame, respectively settle a spring opposite with the return spring force direction to row, specific practice is below the broaching tool frame stage clip to be set, the method is effective to up broaching tool, but along with reducing of the up and amount of spring compression of broaching tool, its effect can weaken gradually; Effect to descending broaching tool is then just in time opposite with our expection, more near the opening terminal point, resistance is big more, the suffered spring flowing heald power of its action effect and up broaching tool is identical, be to have increased the impact that drives after a load and the high position generally, therefore can not effectively do not solve the boosting and the shock problem of a broaching tool high position.
Summary of the invention
In order to reduce operating load inequality of mechanism for electronic jacquard opening and impact noise, the invention provides a kind of up broaching tool and play a driving role, to crossing the only one-way boosting buffer gear in combining the mechanism for electronic jacquard opening that plays the damping buffering effect before flat of the descending broaching tool in high-order back the jacquard shedding mechanism.
To achieve these goals, the technical solution adopted in the present invention is: the one-way boosting buffer gear in a kind of mechanism for electronic jacquard opening comprises the guider screw, the outer stage clip that are installed between following of the stage clip seat of honour and the stage clip and are outwards arranged by the middle; The stage clip seat of honour is hinged on the lower end of lifting rocking bar symmetry bisector by pressing sprung axle, and following of stage clip is hinged on the wallboard by the stage clip lower shaft, and the gyroaxis axis of lifting rocking bar, the axis of pressure sprung axle, the axis of stage clip lower shaft are parallel to each other.
As the further setting of such scheme, between following of the described stage clip seat of honour and the stage clip interior stage clip is installed also, and should in stage clip between guider screw, outer stage clip.
The upper end of described guider screw is fixed on the stage clip seat of honour, and the lower end of guider screw is positioned at the pilot hole of following of stage clip.
One-way boosting buffer gear in the mechanism for electronic jacquard opening of the present invention, operating load inequality of mechanism for electronic jacquard opening and impact noise have been effectively reduced, improve the operational reliability of whole shedding mechanism, had good energy and labour saving effect, and simple in structure, easy for installation.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of existing mechanism for electronic jacquard opening;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 2, the one-way boosting buffer gear in the mechanism for electronic jacquard opening of the present invention comprises guider screw 4, interior stage clip 7, the outer stage clip 8 that is installed between following 6 of the stage clip seat of honour 3 and the stage clip and is outwards arranged by the middle.The upper end of guider screw 4 is fixed on the stage clip seat of honour 3, and the lower end of guider screw 4 is positioned at the pilot hole 10 of following 6 of stage clip.The relative motion that 4 pairs of stage clip seats of honour 3 of guider screw, stage clip are following 6 play the guiding role.The stage clip seat of honour 3 is in positive lower end when combining mean place by pressing sprung axle 2 to be hinged on lifting rocking bar 1, and following 6 of stage clip is hinged on the wallboard by stage clip lower shaft 5.The axis of the axis of the gyroaxis 9 of lifting rocking bar 1, pressure sprung axle 2, the axis of stage clip lower shaft 5 are parallel to each other.
Operation principle of the present invention is: when lifting rocking bar 1 leaves when combining mean place and swinging, in the process of the stage clip seat of honour 3 along with 1 swing of lifting rocking bar, interior stage clip 7, outer stage clip 8 be along carrying out strain by guider screw 4 determined axis directions, and the deformation force of interior stage clip 7, outer stage clip 8 always acts on the up side of lifting rocking bar 1 and the pendulum of going up of lifting rocking bar 1 is produced boosting moment.Extreme position in 1 swing of lifting rocking bar, interior stage clip 7, outer stage clip 8 decrement minimums, but boosting arm of force AD maximum, result of calculation shows at lifting rocking bar 1 leaves (it is 30 ° that this shedding mechanism is combined flat pivot angle to a high position) when combining 20 ° of mean places, boosting moment reaches maximum, boosting moment when a high position is about peaked 2/3, and in when high-order the residue elastic force of stage clip 7, outer stage clip 8 have only combine at ordinary times 1/4, therefore this mechanism has made full use of moment increase principle, has good assist; After lifting rocking bar 1 is crossed high point, interior stage clip 7, outer stage clip 8 again immediately changing function become the resistance of lifting rocking bar 1 from high-order backswing, (reduce to 5: 1-4: 1), impulsive force is reduced, noise reduces thereby changed the load ratio on lifting rocking bar 1 both sides; Carrying out along with motion, interior stage clip 7, outer stage clip 8 progressively are compressed, the deformation energy that the unnecessary deformation energy of the part of return spring is converted into interior stage clip 7, outer stage clip 8 stores, reach maximum compressibility at ordinary times until combining, the pressure position of stage clip 7, outer stage clip 8 is through the centre of gyration A of lifting rocking bar 1 in this moment, boosting moment also is zero, and the damping buffering process finishes, and enters next boosting buffer cycles.
5 times colored types (plain weave) and 600 latitudes on 5/minute the weaving speed condition under, jacquard and the preceding same model machine of repacking that uses one-way boosting buffer gear of the present invention carried out the noise measuring contrast, before using this one-way boosting buffer gear, noise figure is about 85dB, can reach national noise criteria requirement reluctantly; Use the back noise figure to be about 81.5dB, noise reduction is obvious.
Under the condition that does not change existing shedding mechanism physical dimension, one-way boosting buffer gear of the present invention can make lifting rocking bar 1 obtain 20N
*(equivalence) boosting moment of m, by 400 latitudes/minute the conventional weaving speed mean angular velocity that converses lifting rocking bar 1 be 7 radian per seconds, the boosting power that then whole 4 cover lifting rocking bars 1 produce is 0.56 kilowatt, is about the 15-25% of total driving power, has good energy-conserving action.Because the interior stage clip 7 of boosting, the force direction with external applied load is opposite all the time for the active force of 8 pairs of lifting rocking bars 1 of outer stage clip, so therefore the real load of lifting rocking bar 1 block bearing also descends, the reliability of whole shedding mechanism is improved.
