The invention relates to a large-needle-pitch jacquard. The large-needle-pitch jacquard comprises a jacquard substrate and a driving board arranged on the jacquard substrate, the large-needle-pitch jacquard further comprises at least one stretching device fixed on the jacquard substrate, at least one shaft perpendicularly arranged on the jacquard substrate and a connecting mechanism, shaft sleevessleeve the shafts, and the shaft sleeves are fixedly provided with yarn guiding needles; the connecting mechanism is connected between the front end of the stretching devices and the shaft sleeves, and when the stretching devices stretch and contract, the connecting mechanism drives the shaft sleeves to rotate and drive the yarn guiding needles to perform reciprocating swinging between a first position and a second position. The large-needle-pitch jacquard can achieve jacquard weave at a large-needle-pitch position, the displacement of a single needle reaches 8mm or above, the side thrust islarger, and the large-needle-pitch jacquard can be applied to E10 and machine types with a larger needle pitch.
Description
technical field [0001] The invention relates to textile technology, in particular to a jacquard, in particular to a large needle-gauge jacquard. The displacement of the large needle pitch jacquard of the present invention can reach more than 8mm, and has a relatively large side thrust. Background technique [0002] The piezoelectric jacquard widely used at present is limited by the performance of piezoelectric ceramics and the bimorph structure, and the output force and swing displacement of the piezoelectric needle selector are limited. At present, the highest piezoelectric jacquard machine number is E12. The conventional piezoelectric jacquard structure of E10 and larger gauge models can no longer meet the requirements. [0003] For jacquard with large needle distance (such as E3), the existing piezoelectric jacquard cannot be realized. There is still a need in the art for a device capable of realizing jacquard at a position with a large needle pitch. Contents of the i...
