Abstract
The utility model provides a negative shedding mechanism of air jet loom, includes the frame, the heald frame, draw the stay cord, the rope is drawn back to the harness, draw gear, the device is drawn back to the harness, thereby draw the harness to draw or relax downwards, the device that draws back to the harness provides the restoring force for the rope is drawn back to the harness, thereby hoist the harness, still be provided with the baffle of drawing back that is located between the harness and the arm is drawn back to the harness in the frame, consequently can guarantee that the position is accurate that the harness is drawn back to the harness, and in case draw the stay cord fracture, the baffle of drawing back can block it in the top of harness, thereby reach the purpose of protection harness and avoiding warp.
Description
Technical field
The utility model relates to a kind of passive shedding mechanism of air-jet loom, belongs to field of textile machinery.
Background technology
In the prior art, the passive shedding mechanism of air-jet loom comprises frame, heald frame, traction stay cord, returns comprehensive stay cord, and frame is provided with the draw-gear of the described traction stay cord of folding and unfolding, the return device that returns comprehensive arm and restoring force is provided for described time comprehensive arm that makes that described heald frame replys.Because after the long-term work, the traction stay cord is stretched elongated gradually, make back heald frame when comprehensive the position on the upper side, this not only causes draw-gear can't accurately control the position of heald frame, and causes warp thread and breakage of weft easily; In addition, in case the traction stay cord can't bear pulling force and rupture, described heald frame just moves upward rapidly under the pulling force of return device, will cause the heald frame fracture, cause the equipment damage, and the warp thread on the air-jet loom and weft yarn also can be broken, and operating personnel's tap wiring again increases trouble for personnel's operation.
Summary of the invention
The utility model purpose provides a kind of passive shedding mechanism of air-jet loom, even heald frame and warp thread still can guarantee intact under the situation of traction stay cord fracture.
For achieving the above object, the technical solution adopted in the utility model is: a kind of passive shedding mechanism of air-jet loom, comprise frame, liftably be arranged on heald frame on the described frame, the bottom of described heald frame is fixedly connected with the traction stay cord that described heald frame is moved downward, and the bottom of described frame is provided with the draw-gear of the described traction stay cord of folding and unfolding; The top of described heald frame is fixedly connected with go back to an end of comprehensive stay cord, the return device that the top of described frame is provided with back comprehensive arm rotationally and restoring force is provided for described time comprehensive arm, this return device is a spring, the other end of described time comprehensive stay cord is fixedly connected on described time comprehensive arm, also be provided with back comprehensive baffle plate on the described frame, described time comprehensive baffle plate is between described heald frame and described time comprehensive arm, and described time comprehensive stay cord passes comprehensive baffle plate described time, and described time comprehensive baffle plate retaining is above heald frame.
Described time comprehensive baffle plate has two, on described two frames of going back to the left and right sides that comprehensive baffle plates are separately fixed at described heald frame.
Because technique scheme utilization, the utility model compared with prior art has following advantage: the utility model is by setting up back comprehensive baffle plate between described heald frame and time comprehensive arm, make the moving range of heald frame limited, thereby guaranteed under the situation of traction stay cord fracture, heald frame and warp thread are intact, avoid the equipment damage, saved a large amount of work and time of staff.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 6 is the stereogram of baffle plate of the present utility model;
Wherein: 1, motor; 11, belt wheel; 2, plate washer; 31, traction stay cord; 32, return comprehensive stay cord; 4, support wheel; 5, draw-gear; 51, cam; 52, fork; 6, return device; 7, return comprehensive arm; 8, heald frame; 9, frame.
The specific embodiment
Referring to accompanying drawing 1 to accompanying drawing 2, a kind of passive shedding mechanism of air-jet loom, comprise frame 9, liftably be arranged on heald frame 8 on the frame 9, the bottom of heald frame 8 be fixedly connected with traction stay cord 31 that heald frame 8 is moved downward (in this specification " on ", D score position relation is corresponding with the upper and lower position relation shown in the accompanying drawing 1), the bottom of frame 9 is provided with the draw-gear 5 that stay cord 31 is drawn in folding and unfolding.Belt wheel 11 on the rotor portion that draw-gear 5 comprises the motor 1 that is fixedly installed on the frame 9, be fixedly connected on motor 1, the cam 51 that is in transmission connection mutually with this belt wheel 11, draw-gear 5 also comprises the fork 52 that is arranged on rotationally on the frame 9, traction stay cord 31 is connected an end of this fork 52, and the other end of fork 52 then offsets with cam 51.Therefore when motor 1 rotates, but fork 52 reciprocally swingings draw stay cord 31 and heald frame 8 is left behind or loosen heald frame 8 thereby make.
The top of heald frame 8 is fixedly connected with the comprehensive stay cord 32 that returns that heald frame 8 can be sling, the return device 6 that the top of frame 9 is provided with back comprehensive arm 7 rotationally and restoring force is provided for time comprehensive arm 7, return device 7 in the present embodiment is extension spring, and the other end that returns comprehensive stay cord 32 is fixedly connected on back on the comprehensive arm 7.Therefore in the process that heald frame 8 moves downward, return comprehensive stay cord 32 and be subjected to downward pulling force, returning comprehensive stay cord 32 makes the spring of return device 6 be in elongation state by returning comprehensive arm 7, when heald frame 8 is pulled to the minimum point of stroke, traction stay cord 31 is loosened, return device 6 is strained back comprehensive arm 7 immediately, makes it toward back rotation, thereby comprehensive stay cord 32 is sling heald frame 8.Fork 52 reciprocally swingings make heald frame 8 repeat lifting, thereby form opening.
Also being provided with two on the frame 9 returns 2, two on comprehensive baffle plate and returns on the frame 9 of the left and right sides that comprehensive baffle plates 2 are separately fixed at heald frame 8 (" left side " described in the specification, " right side " position relation concerns corresponding with left and right position in the accompanying drawing 1).Two return comprehensive baffle plate 2 all heald frame 8 with return between the comprehensive arm 7, and retaining is above heald frame 8, returns to link to each other with time comprehensive arm 7 after comprehensive stay cord 32 passes back comprehensive baffle plate 2.The comprehensive baffle plate 2 of this time can guarantee that time comprehensive position of heald frame 8 is accurate; And when the fracture of traction stay cord 31, when the pulling force that heald frame 8 is subjected to return device 6 moves upward, return comprehensive baffle plate 2 and will block heald frame 8, limited heald frame 8 and moved up, so just avoided the damage of heald frame 8 and warp thread, just reached the purpose of protecting.
