Description
Technical field
The utility model belongs to air-jet loom field, is specifically related to a kind of tabular connecting rod being applied in jacquard heald mechanism.
Background technology
Jacquard is made up of shedding mechanism, shedding mechanism and decorative pattern controlling organization.The jacquard of adapted on air-jet loom generally uses double action open type mechanism, and air-jet loom rotating speed is more and more higher, reaches 750-1000 rev/min, and the angular speed of the main shaft of jacquard transmission system equals the half of loom main shaft angular speed.Loom main shaft rotates secondary, and the motion of jacquard weave shedding mechanism once circulates, and the jacquard of joining air-jet loom must adapt to 375-500 rev/min.
Shedding mechanism carries warp thread through heald and forms shed open, and heald is significantly upper and lower with warp thread, and warp thread not only follows opening arm and connecting rod moves up and down, and front and back are rocked in harness eye.This is because the shedding mechanism of jacquard is the mechanical part of working condition extreme difference, the parts that also fault rate is the highest, connecting rod is workpiece and the stressed member of jacquard.The structure of the connecting rod of present use is round steel, length of connecting rod can reach 0.5 meter, and two connecting rods drive with one page shedding plate from the left and right sides, and eight connecting rods subject all weight of griffing and warp tension, two connection rod set contracts drive about 2000 warp thread, bear the warp thread load of 1000N.
Between the connecting rod of jacquard is arranged on opening arm and griffes, opening arm drives warp thread to move up and down by connecting rod.The structure of low speed jacquard connecting rod mentions for the purpose of heald to meet in the past, and component is bound up and realizes motion, do not consider distortion and the vibration of parts.Carry on jacquard at height, elongated connecting rod is because of stressed bending and distortion, and shedding plate will produce vibration in the another both direction perpendicular to its direction of motion, and therefore rocking of shedding plate causes warp thread front and back in harness eye to rock.
Warp on loom broken end mainly occurs in heald adjacent domain, and connecting rod gives warp thread the bending transmission of self, exacerbates the friction of warp thread in harness eye, and the too small meeting in connecting rod cross section causes the not cleer and peaceful stop over of opening many.For the design of connecting rod, in its rigidity of increase with while alleviating its quality, the dynamic property of connecting rod must be improved, improve vibration resistance.
