Description

Be equipped with the jacquard weave shedding motion carrying tool rest guiding mechanism

[technical field]

The utility model relates to and is a kind ofly equipped with the jacquard weave shedding motion carrying tool rest guiding mechanism, belongs to jacquard opening technical field.

[background technology]

In the prior art, 8 eccentric wheels be independently arranged on camshaft are positioned at left and right wallboard both sides, and wherein, four large eccentricities wheel drives two groups to griffe up-down alternative motion, to form big uncork by vertical connecting rod after four jointly; Four small eccentricities wheel drives two groups to griffe up-down alternative motion by four front vertical connecting rods jointly, thus forms little opening.But this existing jacquard weave shedding motion exists following not enough:

1, complex structure cost is higher, owing to using 8 eccentric wheels, eccentric wheel processing coherence request is high, and 8 eccentric wheels are installed on all separately on a camshaft, complicated difficult is installed to ensure that eccentric group is mounted opposite angle, finally cannot ensure that one group when griffing to rise to top dead center position and another group griffes to drop to bottom dead center position simultaneously, vice versa.Two groups of synchronous up-down alternative motions of griffing are met because large and small eccentric wheel cannot synchronously drive, cause that upper and lower opening in weaving process is asynchronous, opening is unintelligible, and affect the reciprocal precision of needle assembly and dress and make the warp worn and produce and be unfavorable for woven beating, finally there is the problem that end breakage is high, weaving efficiency is low;

2, large eccentricity wheel is different from the specification that small eccentricity is taken turns, not general mutually;

3, griffe for a pair frame and another only do upper and lower elevating movement by forward and backward vertical connecting rod merely to griffing frame, kinematic accuracy is low, and movement locus is undesirable, makes two to there is the large deficiency of laterally offset to griffing frame due to motion credibility difference.

[utility model content]

Technical assignment of the present utility model is that providing a kind of is equipped with the jacquard weave shedding motion carrying tool rest guiding mechanism, this device not only can be griffed frame to two couple of upper and lower alternate reciprocating motion and be carried out effective vertically guiding, it is little to griffe frame laterally offset, and two to griffing frame reverse high, the good stability of the synchronism of alternate reciprocating motion each other.

Technical assignment of the present utility model is achieved like this:

Be equipped with the jacquard weave shedding motion carrying tool rest guiding mechanism, comprise two to griffing frame, be arranged on a camshaft on a framed side wallboard, article one, be set in the center balance staff on a framed side wallboard and opposite side wallboard, article one, be set in the concentric balance staff pipe of on a framed side wallboard and opposite side wallboard and sheathed described center balance staff, stretch out between camshaft one end of a framed side wallboard and the balance staff one end, center of stretching out a described framed side wallboard and be provided with an outer eccentric wheel outside connecting rod outside crank mechanism, stretch out between camshaft one end of a framed side wallboard with the concentric balance staff pipe one end of stretching out a described framed side wallboard and be provided with eccentric wheel inside connecting rod inside crank mechanism in, rocking bar and rear rocking bar before the both sides of center balance staff are provided with respectively, rocking bar and rear rocking bar before the both sides of concentric balance staff pipe are provided with respectively, be loaded on front rocking bar on the balance staff of center and be loaded on rear rocking bar on concentric balance staff pipe all by vertical connecting rod with to griffe frame for a pair and be flexibly connected, be loaded on rear rocking bar on the balance staff of center and be loaded on front rocking bar on concentric balance staff pipe and be all flexibly connected griffing frame with another by vertical connecting rod, its improvement is: also comprise and to griffe the identical two cover guiding mechanisms of the structure of frame alternate reciprocating motion described in can vertically guiding, the a set of guiding mechanism be arranged near each framed side wallboard comprises second mate's leading arm, the spindle seat being installed on bottom framework rear portion and the mandrel be loaded on this spindle seat, each installation end of second mate's leading arm is all hubbed on this mandrel, each vertical pendulum moved end of second mate's leading arm is then articulated with corresponding one respectively griffing on frame, inside and outside eccentric wheel has equal aperture axis and the consistent compound whole body structure of symmetry of concentricity.

The utility model tool has the following advantages and beneficial effect:

1, owing to being loaded on same camshaft, outer eccentric wheel has equal aperture axis and the consistent compound whole body structure of symmetry of concentricity, eccentric wheel can realize directly simple installation, and do not exist in needs adjustment, outer eccentric eccentric established angle potential difference problem, stop the generation of setting angle error, in this structure, in outer eccentric wheel makes, outside connecting rod is in driving, in outside crank swing process, achieve inside crank and the reverse each other high synchronism of outside crank, amplitude of oscillation high consistency swings, and the high synchronism that center balance staff is reverse each other with concentric balance staff pipe, amplitude of oscillation high consistency swings, thus, in the whole gyration process of camshaft, conversion of motion is two to griffing the metastable high synchronism reciprocating motion that frame oppositely replaces each other, two pairs of reverse sync of griffing frame are constantly by this structure, outer eccentric wheel is drived control simultaneously, therefore, the utility model ensure that the jacquard weave harness motion time has accurate synchronism.

Because jacquard weave opening synchronism is high, opening is clear, significantly reduce the unfavorable of warp thread and beat when high speed jacquard is weaved, therefore, cracked ends rate obtains effective control, and weaving efficiency is high.

2, by guider of the present utility model, leading arm can be griffed frame to two couple of upper and lower alternate reciprocating motion and be carried out effective vertically guiding, and contribute to balance and griffe frame in opening process, laterally offset reaches and minimizes; Each installation end due to all leading arms is all hubbed on big uncork side (i.e. orientation, bottom framework rear portion) towards on consistent mandrel, and upper and lower frame of griffing all affects by the balance guiding of leading arm at top dead center position, bottom dead center position respectively, seems advantageously.
