Abstract
The utility model discloses a shedding mechanism used for an electronic jacquard. The shedding mechanism comprises a single crank main shaft, an eccentric slide block, a synchronous connecting rod, small and big shedding rocking rods, a knife lifting frame, a connecting rod, a lifting knife and a movable hinge, wherein, the single crank main shaft is rotationally connected with the eccentric slide block in the sliding channel of the synchronous connecting rod, the synchronous connecting rod is connected with the small and big shedding rocking rods through hinges, the knife lifting frame is connected with the rocking rods through the connecting rod in a suspending way, and the lifting knife is connected with the knife lifting frame through the movable hinge in a suspending way and is spliced with a nylon sliding chute.
Description
Technical field
The utility model belongs to the electronic jacquard machine technical field, relates to a kind of mechanism for electronic jacquard opening.
Background technology
Electronic jacquard machine is in the existing application very widely of textile industry, and mechanism for electronic jacquard opening is the important component part of electronic jacquard machine.
At present, reasonable double-lift mechanism for electronic jacquard opening is that the crank double-lift is griffed shedding mechanism on the market, and this mechanism is the center rotation with the main shaft by eccentric wheel, is driven by connecting rod and griffes frame and do and pump, griffe to be installed in and griffe on the frame, thereby realized the upper and lower opening motion.Because adopted double eccentric wheel to griffe shelf structure, main shaft rotates 180 °, drives simultaneously and griffes from top to bottom, has finished harness motion one time, has guaranteed that the loom running finishes harness motion one time for 360 °.And main shaft rotates 180 °, griffes to finish again from the bottom to top one time harness motion.This mechanism cooperates running with loom, its speed of mainshaft is half of loom rotating speed.
But the structure more complicated of this mechanism, robust motion is bad.
The utility model content
At problems of the prior art, the utility model purpose is to design the technical scheme that a kind of more simple mechanism for electronic jacquard opening is provided.
For achieving the above object, the technical scheme that the utility model is taked is: mechanism for electronic jacquard opening, comprise single crank main shaft, eccentric shoe, size openings rocking bar, synchronising (connecting) rod, griffe frame, connecting rod, hinges, griffe etc.The single crank main shaft is rotationally connected with the interior eccentric shoe of synchronising (connecting) rod slideway, synchronising (connecting) rod is connected with hinge with two pairs of size openings rocking bars, griffe frame and hang by connecting rod and size openings rocking bar and be connected, griffe by hinges with griffe frame and hang and to be connected, griffe to peg graft with the nylon chute.
Because the utility model utilization with the double-lift mechanism for electronic jacquard opening of slider-crank mechanism transmission, drives the size openings rocking bar by synchronising (connecting) rod, so realized reciprocally swinging, simple in structure, processing cost is low, and motion is steady, good reliability.Owing to griffing frame and the form that adopts hinges that is connected of griffing, so that griffe all the time in the fixing slideway of two ends, to do straight line up and down and move and changed the conditional electronic jacquard lifting knives and make the mode that swings up and down along camber line, make moving up and down of griffing more steady, also can not wipe mutually with the needle selection device on two limits.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is movement velocity, the acceleration change tracing analysis figure of the utility model rocking bar.
Among the figure, 1. single crank main shaft, 2. synchronising (connecting) rod, 3. rocker shaft is 4. griffed frame, 5. griffes frame, 6. connecting rod, 7. rocking bar is 8. griffed, 9. hinges, 10. eccentric shoe.
The specific embodiment
Below in conjunction with Figure of description the utility model is elaborated, and provides the specific embodiment.
As shown in Figure 1, mechanism for electronic jacquard opening, comprise single crank main shaft 1, synchronising (connecting) rod 2, griffe frame 4, griffe frame 5, connecting rod 6, size openings rocking bar 7, griffe 8, hinges 9, eccentric shoe 10, single crank main shaft 1 is rotationally connected with the interior eccentric shoe 10 of synchronising (connecting) rod 2 slideways, synchronising (connecting) rod 2 is fixedlyed connected with two pairs of size openings rocking bars 7, griffe frame 4 with griffe frame 5 and hang with large and small opening rocking bar 7 by connecting rod 6 and be connected, griffe 8 by hinges 9 with griffe frame 4, griffe frame 5 and hang and is connected, griffe 8 with the grafting of nylon chute.
Drive when single crank main shaft 1 rotates be installed in synchronising (connecting) rod 2 slideways eccentric shoe 10 along slideway slide up and down (two sine mechanism) promote synchronously moving connecting rod and do side-to-side movement, promote size openings rocking bar 7 and rocker shaft 3 and make left and right sides reciprocally swinging, thereby drive by connecting rod 6 hang on the rocking bar 7 griffe frame 4 with griffe frame 5 and do staggered up and down reciprocating motion, griffe 8 to hang on by hinges 9 and to griffe on the frame, and do translation up and down along with griffing swinging up and down of frame.Heavy curtain is moving in order to prevent to griffe when moving up and down, and inserts and is installed in before and after the electronic jacquard machine in the nylon chute on the wallboard griffing 8 two ends, makes and griffes to do translation up and down along chute.The two pairs of size openings rocking bars 7 couple together with synchronising (connecting) rod 2 usefulness hinges, make griffe frame 4 with griffe frame 5 and do synchronous upper and lower swing, make the torsion of balance staff reduce half, and both sides are stressed evenly.
As shown in Figure 2, be movement velocity, the acceleration change tracing analysis figure of the utility model rocking bar.Illustrate that the mechanism for electronic jacquard opening that the utility model provides is stressed evenly, its speed and acceleration evenly change continuously, and dynamic loading is less, is applicable to the reciprocating machinery of high speed.
The every content that can associate or derive from the disclosed content of the utility model is all thought protection domain of the present utility model.
