Technical field
The present invention relates to a kind of conjugate cam type rapier transmission mechanism of sword pavilion loom, belongs to sword pavilion loom textile technology field.
Background technology
Rapier loom is the shuttleless loom being most widely used at present, it is in addition to the characteristics of shuttleless loom high speed, high automaticity, high-effect production, its positive filling insertion way has very strong varietal adaptation, adapt to the wefting insertion of all kinds of yarns, in addition rapier loom also has obvious advantage in terms of more barry dyeing weavings, can produce the Yarn-dyed fabric of up to 16 barry dyeing yarns.As shuttleless loom substitutes fly-shuttle loom, rapier loom is by as the main production machine of woven fabric.In the extensive use of microelectric technique, the speed and wefting insertion rate for making rapier loom greatly improve.In various filling insertion way, in projectile shuttle wefting insertion, rapier weft inserting, pneumatic picking and water jet weft insertion system, rapier weft inserting speed is in addition to pneumatic picking and very high.Rapier loom mainly designs to solve Weft insertion method, including rigidity, flexible and extension type filling insertion way, its major product is clothes fabric, compared with other filling insertion way, the filling insertion way of rapier loom is adapted to multicolor weft insertion, the product of the multimodal pattern design of 12 color wefting insertion can be produced, including various types of yarns, the various types of fabrics of production, yarn that can be relatively difficult to many wefting insertion completed wefting insertion in the past.
Important mechanism is rapier transmission mechanism in sword pavilion loom, and rapier transmission mechanism mainly has the forms such as conjugate cam driving, the driving of space crank connecting link, eccentric ratio driving and space screw drive.The traverse of conjugate cam driving rapier transmission mechanism is smaller, and the speedup of transmission system is larger, and the accuracy of manufacture requires high；But it is in the work(course of work is transported, because existing conjugate cam driving mechanism designs not reasonable, wears larger between cam, easily cause the accident of sluff-offs, in order to ensure being smoothed out for bringer, further to design and plan conjugate cam rapier transmission mechanism.
The content of the invention
It is an object of the invention to：The defects of for prior art; propose a kind of conjugate cam type rapier transmission mechanism of sword pavilion loom; the mechanism structure is simple, reasonable in design; on the one hand the abrasion between conjugate cam can effectively be avoided; the trouble-free operation of rapier transmission mechanism is ensure that, improves the efficiency of bringer and the degree of accuracy of bringer coordinate, while stable movement and driving-chain are short; parts are easy to process, and cost is relatively low.
The technical solution adopted in the present invention is：A kind of conjugate cam type rapier transmission mechanism of sword pavilion loom; including conjugate cam group, connecting rod, power transmission shaft, sliding block, sector gear, little gear and balance staff; one end of the connecting rod is provided with sector gear; the other end of connecting rod is provided with sliding block; conjugate cam group is provided between sliding block and sector gear; balance staff is provided between conjugate cam group and sliding block; the top of balance staff is provided with upper roller; lower section is provided with lower roller; the fan-shaped wheel hub surface of wherein described sector gear connects with little gear; little gear is located at one end of power transmission shaft, and the other end of power transmission shaft is provided with spiral bevel gear.
In the present invention：The lower section of described spiral bevel gear is provided with conical gear, and conical gear is located at one end of sword belt, and conical gear is connected by sword belt with the biography sword gear of the sword belt other end.
In the present invention：Described conjugate cam group includes conjugate cam one and conjugate cam two, and loom main shaft is provided between conjugate cam one and conjugate cam two, and conjugate cam one is connected with conjugate cam two by loom main shaft.
After adopting the above technical scheme, beneficial effects of the present invention are：The present invention is simple in construction, reasonable in design, on the one hand can effectively avoid the abrasion between conjugate cam, ensure that the trouble-free operation of rapier transmission mechanism; improve the efficiency of bringer and the degree of accuracy of bringer coordinate; stable movement and driving-chain are short simultaneously, and parts are easy to process, and cost is relatively low.
