Description
Technical field
The utility model is related to loom field, specifically a kind of shedding mechanism of weaving machine.
Background technology
The shedding mechanism of control single thread is made and spring-return mechanism group using electronic jacquard machine, dress mostly in the market
Into its major defect is：Opening stroke is small, it is impossible to the need for meeting specialities to warp thread big opening, while because of spring-return
Clear opening can not be effectively formed to thick and heavy yarn and highdensity yarn tissue, the development of weaving technology is restricted.
The content of the invention
For above-mentioned the deficiencies in the prior art, it is all hardness that the utility model, which is carried there is provided one kind, returned, and openings of sizes is adjustable
Scope is big, and can realize big opening stroke, adapt to the shedding mechanism of weaving machine of high density Warp opening.
The technical solution adopted in the utility model is：A kind of shedding mechanism of weaving machine, including rack-mounted two groups with
Pull-up carries component, it is characterised in that：The drawing carries component and tightened up including electronic box, numerical control La Ti mechanisms, position signalling mechanism, drawstring
It is each passed through above and below device, drawstring and upper and lower assembly pulley, drawstring in the middle part of the upper and lower keevil in frame, drawstring and is provided with pinhole, is drawn
Upper and lower bypass respectively of rope connects set location signaling gear on numerical control La Ti mechanisms, drawstring after upper and lower assembly pulley, position letter
Number mechanism and numerical control La Ti mechanisms connection electronic box.
Further, described a kind of shedding mechanism of weaving machine, it is characterized in that：On the drawstring tightening device concatenation drawstring,
The drawstring tightening device is elastomer or collapsible spiro rod regulating device.
Further, described a kind of shedding mechanism of weaving machine, it is characterized in that：The numerical control La Ti mechanisms pass through for numerical-control motor
Reducing gear connects pulley disc.
Further, described a kind of shedding mechanism of weaving machine, it is characterized in that：The position signalling mechanism include drop-down, on
Propose signal source and drop-down, above carry position sensor；It can be one or more metal or non-gold to pull down, above put forward signal source
Category；The position signalling mechanism can also be proximity switch or encoder or high-precision meter counter or contact switch.
Further, described a kind of shedding mechanism of weaving machine, it is characterized in that：The upper and lower pulley block structure is similar, can root
According to be actually needed increase or decrease assembly pulley realize drawstring commutate.
Using above-mentioned technical proposal, the beneficial effects of the utility model are：Worn in pinhole when connecing warp thread and needing upper and lower opening,
Numerical-control motor is controlled by electronic box, numerical-control motor connects pulley disc through reducing gear, and the upper and lower end of drawstring is each passed through in frame
Upper and lower keevil and it is connected on pulley disc after bypassing upper and lower pulley successively, drives drawstring one end to batch in pulley disc, the other end
When unreeling, tension is controlled to ensure that drawstring is tensed all the time by spring, with reference to multiple position signalling source respective sensor controls on drawstring
The stroke up and down of pinhole meets openings of sizes requirement on drawstring processed, and position sensor, which is set, can effectively ensure that pinhole displacement is accurate,
Reply is proposed so as to realize that hardness is drawn, the wide adjusting range of openings of sizes is met, high density, the clear of thick and heavy yarn tissue is adapted to and opens
Mouthful, the friction between warp thread, weft yarn can be prevented effectively from, weave quality is improved.
