Background technology
The modern computer straight-bar machines is the application examples of Knitting Machinery electromechanical integration on Knitting Machinery, the Computerized flat knitting machine that simply is divided into dual system and single system, the Computerized flat knitting machine of single system is briefly just the same with the straight-bar machines that stops of hand knitting machine, simple in structure, needle plate is the simple needle plate the same with hand knitting machine, can realize braiding, turns over pin, do not knit function, but can not be in delegation loop construction be woven braiding and tuck effect.The Computerized flat knitting machine of dual system is two heads and together, and it once is 4 row (2 change) that head walks up and down, and pin is turned in braiding that can be random, and the tuck velocity ratio is very fast, but price, operating cost are higher.How make on the basis of the computer flat-knitting machine head that does not increase single system and loop construction is woven braiding in the Computerized flat knitting machine of single system has with delegation and the tuck effect is the object that those skilled in the art study always.
The Computerized flat knitting machine of single system is a kind of crosspointer plate latch needles weft knitting loom.Its triangle device is just as one group of plane cam, and the stitch of knitting needle can enter in the conduit of cam, and mobile triangle forces knitting needle to do regular elevating movement in the needle tray of needle plate, and colludes action with needle latch by pin, just yarn can be woven into knitted fabric.Knitting needle is in uphill process, and coil progressively withdraws from pin and colludes, and opens needle latch, and withdraws from needle latch and hang on the shank; Knitting needle is in the decline process, and pin catches on the yarn that new pad is put, and its tractive is bent to coil, original coil of while is then deviate from pin and is colluded, new coil passes from old coil, is together in series with old coil, and the coil string that numerous knitting needles is made into connects mutually and formed knitted fabric.
Knitting needle is called knitting cycle with the process that the braiding track of yarn by triangle device is made into fabric, and knitting cycle can be divided into and moves back circle, the pad yarn, and the band yarn is remained silent lasso, knocking over, 8 stages such as lopping and tractive.
A. move back circle
Move back circle and will be in the old coil of pin in colluding exactly and move on the shank, put new yarn for pad and get ready. in moving back the circle process, knitting needle rises to peak from minimum point, and knitting needle is in and moves back the circle stage, moves back circle back needle latch and is scraped off by coil.
B. fill up yarn
The pad yarn is put into yarn on the needle latch exactly, finish move back circle after, knitting needle begins to descend, owing to give the interoperation of yarn mechanism, yarn just under the guiding of thread-carrier, by the yarn mouth by pad be put into that pin colludes below, above the needle latch, so that knitting needle is when continue descending, pin colludes and can catch on yarn reliably.
C. be with yarn
The band yarn is exactly pad to be put into pin collude following yarn and guide to the process of pin in colluding. and this process is to rely on fabric to descend to finish.
D. remain silent
Remaining silent is the anesthesia needle mouth, the old coil of the yarn that new pad is put is separated by needle latch. after not being with the yarn process to finish, yarn is correctly caught on by pin, knitting needle continue to descend, and the old coil of falling on the shank slides to syringe needle along shank, move on to needle latch below, needle latch is because the effect of old coil, the rotation of beginning cast-over tongue axle, when knitting needle descended again, the needle latch rotation covered pin and colludes the anesthesia needle mouth.
E. lasso
The lasso process is to be set on the needle latch of having closed from old coil, then moves on to the pin place of colluding and finishes along having closed needle latch.
F. knocking over
Knocking over is exactly the process that coil splits away off from syringe needle. and after finishing lasso, knitting needle descends along the triangle working face, catch on the yarn that new pad puts and pass old coil, and old coil is simultaneously because the effect of traction force, and deviate from the place by syringe needle.
G. lopping
The work in lopping stage is after old coil is deviate from syringe needle, and pin colludes is with the yarn that new pad is put to pass old coil, and knitting needle descends the coil of general who has surrendered's yarn stretch bending Cheng Xin again.
H. tractive
Tractive is exactly in order to make the new coil after the lopping be able to tensioning, must not deviate from pin colludes, to carry out the lopping work of next line braiding. tractive is to utilize draw-off mechanism that old coil is pulled to needle back, reaches nervous purpose, and the fabric that will be shaped is drawn knitting point simultaneously.
Tuck is one of fundamental line circular structure of knitted fabric tissue, and it is that old coil will not be moved back circle or knocking over, and knitting needle continues lopping, and new and old coil gathers together and a kind of tissue of forming.
