The present invention the course of work be：Automatically increase or decrease yarn take yarn device purpose can be achieved on automatically increase or decrease yarn work will
Ask.
In Zai Sha mechanisms 7, yarn is drawn from tube 22, and pulley B 31 and pulley A are sequentially successively bypassed respectively
26, most passed afterwards after pulley A 26 behind the top for taking yarn device main body 38, by increasing and decreasing yarn mechanism, final thread, which is fed to, to be taken
Woven extent above yarn device participates in knitting.Equivalent to one fixed pulley of pulley B31 herein, pulley A26 is equivalent to one
Movable pulley.By common effect, the control acted charitably is entered to yarn tension come the yarn device of taking that enables, because whether can be to yarn
The stable control of power is to evaluate an important indicator for taking yarn device, is also a final favourable conditions for ensureing weave quality.
When yarn tension is excessive, because there are two springs between crossbeam 29 and crossbeam lower axle 24 on support frame 33
28, then now tension force pulls the pulley A 26 to have the trend moved upwards, spring 28 can compress realize by pulley A 26 to
Upper regulation, so as to realize the reduction of yarn tension.
When yarn tension is too small, similarly, existing because of between the crossbeam 29 and crossbeam lower axle 24 on support frame 33
Two springs 28, now two springs 28 are due to the effect of the restoring force of itself, it is possible to achieve the work for adjusting pulley A26 downwards
With so as to realize the increase of the tension force of yarn.
During braiding, it is controlled by 6 pairs of number of yarns for participating in braiding of increase and decrease yarn mechanism, when yarn is from load
When yarn mechanism 7 is conveyed upwards into increase and decrease yarn mechanism 6, yarn is stopped in solid yarn device, is joined through solid yarn ring 12 and solid yarn device support 9
With braiding process.
The course of work of yarn device is taken to when subtracting yarn and increasing yarn, this automatically increases or decreases yarn individually below to illustrate,
(1) when needing to reduce yarn, automatically increase or decrease yarn and take the motor 34 of yarn device and obtain the signal of a main story, just
It can be rotated and rotated clockwise with motor gear 35, so as to control turning clockwise for mainshaft gear 37 by the transmission of cingulum 36
It is dynamic, because selector is fixed on main shaft, it can also rotate clockwise therewith, so as to realize that cutoff tool 18 is transported for the cutting of yarn
It is dynamic, reduce the yarn for participating in braiding successively by way of rotation.Yarn device of the present invention of taking carries 4 tubes, therefore, can
To realize that each braiding yarn for taking yarn device main body, from 4, is reduced to 3,2, the situation of 1.
(2) when needing increase yarn, automatically increase or decrease yarn and take the motor 34 of yarn device and obtain the signal of an anti-pass, just
It can be rotated and rotated counterclockwise with motor gear 35, so as to control turning counterclockwise for mainshaft gear 37 by the transmission of cingulum 36
It is dynamic, because selector is fixed on main shaft, it can also rotate counterclockwise therewith, now because the back side of cutoff tool 18 is the circle of setting
Sliding contact surface, so cutoff tool 18 can push to be arranged on solid yarn device support 9 under rotation counterclockwise pushes movable block
11, the wedge structure of compact heap 10 can be promoted by pushing movable block 11 so that compact heap 10 promotes jacking block 10-1 to promote pressure yarn end 12-
Moved in 1 towards the institute yarn ring 12-2 in solid yarn ring 12, realize that solid yarn ring 12 completes the requirement of yarn locking, consolidate 2 one threads
It is scheduled on together.After solid yarn ring 12 completes to compress self-locking, the position that compact heap 10 is returned in the presence of spring 13,
Working cycles next time are waited, the braiding process that 1 one thread becomes 2 one threads is just realized.It is of the present invention to take yarn device 4
Yarn device main body 38 is taken including some, each taking yarn device main body 38 includes 4 tubes and 4 solid yarn devices, it is thereby achieved that often
The individual braiding yarn for taking yarn device main body increases as 2,3, the situation of 4 from 1 one thread.
