Description
Technical field
The invention belongs to the technical field of auxiliary facilities of computer plain flat knitter, and in particular to a kind of computer plain flat knitter
Thread nipper assembly.
Background technology
As is known in the industry, when the knitting mechanism of computer plain flat knitter weaves coloury fancy cloth, need to make
With the yarn of corresponding color, the color of fancy cloth is abundanter, and the kind of the yarn of different color and lusters is also corresponding more, and what is enabled feeds
The same example of yarn shuttle, because each shuttle can only feed a kind of yarn of color to knitting mechanism.Then when yarn will be changed, then first
The front shuttle for participating in work just temporarily exits yarn feeding state, while the yarn on the shuttle of state of this being deactivated by scissors apparatus
Line is cut off and is clamped by thread nipper assembly, in case entering yarn feeding work next time, i.e., is temporarily in holding state, and changes
The shuttle of the yarn of color enters yarn feeding state.It follows that whenever shuttle changing once, scissors apparatus are just cut off once to yarn,
Yarn is just clamped once by thread nipper assembly simultaneously.In addition when view picture fabric（Industry custom claims a slice, thin piece）After braiding is finished,
Need to be cut off by the yarn on the shuttle that scissors apparatus will participate in weaving and yarn is clamped by thread nipper assembly.Therefore thread nipper assembly is
The end of the needle-bar of computer plain flat knitter is arranged on scissors apparatus（The two ends of needle-bar are respectively mounted）, by yarn clipping with cut
The collaborative work of yarn is realized cutting the automation of yarn clipping.
Can be seen in disclosed Chinese patent literature with regard to the technical information of thread nipper assembly, typically such as
" the flat machine clamp dress that " the computer plain flat knitter wire-clamping device " and CN202323305U that CN202175810U recommends is provided
Put ", although two patent formulas technique effect respectively described in the technique effect hurdle with specification, exist following logical
Disadvantage：As yarn clipping refers to that the structure of mechanism is lost rationally, thus easily occur following two being not intended to during actual use
Occur but unavoidable two kinds of situations, one is that, when very thin yarn is run into easily by pinch off, two is when textured yarn is run into
Easily shake off and cause yarn clipping to fail.Therefore the adaptability to thickness of yarn how is improved into the functional reliability for considering thread nipper assembly
Key factor.
For above-mentioned prior art, very there is improved necessity, be that this applicant has made positive and beneficial design repeatedly
With test, technical scheme described below is defined finally.
