Technical problem to be solved in the utility model is to provide a kind of reasonable in design, equipment investment cost is low, Filling Insertion Time can be made sufficient when weaving at a high speed, when opening, tension variation is more even, is suitable for various plain cloth woven air-jet loom crank shedding mechanism.
For solving the problems of the technologies described above, the technical solution of the utility model is: air-jet loom crank shedding mechanism, be arranged in the frame of loom, comprise heald frame and opening crank, described opening crank is connected with drive unit, also comprises opening fork and shedding axle, is connected in the middle part of described opening fork by rotating shaft with described gantry rotation, described shedding axle is rotatably installed in described frame, described shedding axle is fixed with shedding connecting rod and shedding pin; Be connected with the first opening connecting bar between one end of described opening fork and described opening crank, be connected with the second opening connecting bar between the other end of described opening fork and described shedding connecting rod, between described shedding pin and described heald frame, be connected with shedding adjusting lever.
As preferred technical scheme, described opening fork one end is by the first opening connecting bar described in pinned connection, the other end of described opening fork offers chute along body of rod length direction, moving pin is provided with in described chute, described moving pin two ends are set with movable block, be provided with locking device between described movable block and described opening fork, described second opening connecting bar is sleeved on described moving pin.
As the improvement to technique scheme, described opening crank is connected with described first opening connecting bar by bearing pin.
As the further improvement to technique scheme, described second opening connecting bar is connected with described shedding connecting rod by bearing pin.
As the further improvement to technique scheme, described shedding pin is connected with described shedding adjusting lever by bearing pin.
As the further improvement to technique scheme, described opening fork bends S-type.
Owing to have employed technique scheme, air-jet loom crank shedding mechanism, be arranged in the frame of loom, comprise heald frame and opening crank, described opening crank is connected with drive unit, also comprises opening fork and shedding axle, is connected in the middle part of described opening fork by rotating shaft with described gantry rotation, described shedding axle is rotatably installed in described frame, described shedding axle is fixed with shedding connecting rod and shedding pin; Be connected with the first opening connecting bar between one end of described opening fork and described opening crank, be connected with the second opening connecting bar between the other end of described opening fork and described shedding connecting rod, between described shedding pin and described heald frame, be connected with shedding adjusting lever; The utility model has following beneficial effect: opening slow-action when achieving fabric, Filling Insertion Time can be made sufficient when weaving at a high speed, and doubtful angular stop is set below opening, the open curve of special pearl, make upper and lower layer warp thread form Tension Difference when beating up, the tension variation when opening is more even, the surface texturisation of fabric can be significantly improved, make fabric plentiful, even if when running up, also can obtain obvious cracked ends and improving.Simultaneously, owing to eliminating the cam shedding mechanism of transmission complexity, the cost of investment of end equipment can significantly be fallen, opening crank and the opening fork of optimal design make device have high-speed adaptability, improve equipment reliability of operation, the machine thing consumption of weaving process also obviously reduces, and is very suitable for long-term large the various tabby of order volume and weaves.
