Abstract
The present invention relates to a kind of shedding mechanism of weaving machine, wear 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, drawstring upper, lower end is each passed through upper in frame, lower keevil and bypass successively, it is connected to after lower sheave on pulley disc, drawstring one end is driven to batch in pulley disc, when the other end is unreeled, tension is controlled by spring guarantees that drawstring is tensed all the time, stroke up and down in conjunction with pinhole on multiple position signalling sources respective sensor control drawstring on drawstring meets openings of sizes requirement, position sensor is arranged can effectively guarantee that pinhole displacement is accurate, so as to realize that rigid drawing proposes reply, meet the wide adjusting range of openings of sizes, adapt to high density, the clear opening of thick and heavy yarn tissue, warp thread can be prevented effectively from, friction between weft yarn, improve weave quality.
Description
Technical field
The present invention relates 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 little, it is impossible to meet needs of the 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.
Content of the invention
For above-mentioned the deficiencies in the prior art, the invention provides it is all rigid, openings of sizes adjustable extent that one kind is carried, returned
Greatly, and can achieve big opening stroke, adapt to the shedding mechanism of weaving machine of high density Warp opening.
The technical solution used in the present invention is：A kind of shedding mechanism of weaving machine, including rack-mounted drawing more than two
Carry component, it is characterised in that：The drawing carries component includes that dress tightened up by electronic box, numerical control La Ti mechanisms, position signalling mechanism, drawstring
Put, drawstring and upper and lower assembly pulley, drawstring is each passed through the upper and lower keevil in frame up and down, is provided with pinhole, drawstring in the middle part of drawstring
Upper and lower bypassing respectively connect after upper and lower assembly pulley numerical control La Ti mechanisms, set location signaling gear on drawstring, position signalling
Mechanism and numerical control La Ti mechanisms connection electronic box.
Further, a kind of described shedding mechanism of weaving machine, is characterized in that：On the drawstring tightening device concatenation drawstring,
The drawstring tightening device is elastomer or collapsible spiro rod regulating device.
Further, a kind of described shedding mechanism of weaving machine, is characterized in that：The numerical control La Ti mechanisms are passed through for numerical-control motor
Reducing gear connects pulley disc.
Further, a kind of described shedding mechanism of weaving machine, is characterized in that：The position signalling mechanism include drop-down, on
Carry signal source and drop-down, above carry position sensor；Drop-down, above to put forward signal source can be one or more metal or non-gold
Category；The position signalling mechanism can also be proximity switch or encoder, be alternatively high accuracy meter counter or contact switch.
Further, a kind of described shedding mechanism of weaving machine, 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.
Above-mentioned technical proposal is adopted, the invention has the beneficial effects as follows：Wear in pinhole when connecing warp thread and needing upper and lower opening, by electricity
Case controls numerical-control motor, and numerical-control motor connects pulley disc through reducing gear, the upper and lower end of drawstring be each passed through in frame upper,
Lower keevil and it is connected on pulley disc after bypassing upper and lower pulley successively, drives in pulley disc that drawstring one end is batched, the other end is unreeled
When, controlling tension by spring guarantees that drawstring is tensed all the time, draws in conjunction with respective sensor control in multiple position signalling sources on drawstring
On rope, the stroke up and down of pinhole meets openings of sizes requirement, and position sensor is arranged can effectively guarantee that pinhole displacement is accurate, so as to
Realize that rigid drawing proposes reply, meet the wide adjusting range of openings of sizes, adapt to high density, the clear opening of thick and heavy yarn tissue,
The friction that can be prevented effectively between warp thread, weft yarn, improves weave quality.
