Technical Field
The invention belongs to the technical field of knitting machinery, and particularly relates to a double-knitting-needle combination mechanism of a flat knitting machine.
Background
At present, full-forming knitting is generally realized by the traditional needle bed needle-separating knitting or the composite needle bed by means of the needle sending. When the traditional needle bed is used for knitting at a distance from needles, the needle pitch formed by the spaced needles cannot reach the standard needle pitch of a common flat knitting machine, the needle pitch is greatly increased, so that the arc lines between the coils are long, the density of the knitted fabric is low, the requirements on the elasticity and the strength of the knitted fabric are high, and meanwhile, the whole effect of the knitted sweater is poor due to the fact that the normal needle pitch cannot be reached. The composite needle bed knitting refers to multi-needle bed knitting, the knitting needles are arranged up and down, in the knitting process, due to structural reasons, the head of the upper knitting needle cannot be close to a cylinder mouth formed by the front end of a needle plate and a tooth mouth piece like the head of the lower knitting needle, the looping is difficult when the upper knitting needle is knitted, the requirements on the strength and the elasticity of wool yarns are high, the knitting process is complex, the structure is also complex, the manufacturing difficulty of the special knitting needle is high, and the production cost is high.
Patent application 202010316107 discloses a faller knitting needle combination for flat knitting machine, both sides around locating the frame of flat knitting machine, including the faller that is equipped with a plurality of needle grooves, locate the knockover piece of a plurality of parallels of faller front end, locate knitting needle and the stitch of needle inslot, and knockover piece and faller front end constitute the nozzle that the knitting formed, and the needle inslot between the two adjacent knockover pieces is equipped with about arranging and can accomplish two pieces of knitting needles including knit, tuck knit and loop transfer knit separately. The device solves the problem of full-forming knitting of the composite needle bed through a scheme of one groove and two needles, but two knitting needles are arranged in parallel, as shown in fig. 9, spring pieces of the two knitting needles are positioned on the same side, namely one knitting needle is positioned at one side of the spring piece close to a tooth mouth piece, and the other knitting needle is positioned at one side of a non-spring piece close to the tooth mouth piece, so that the distance between the two knitting needles and the tooth mouth pieces at the two sides is inconsistent, and the gap between one side of the non-spring piece and the tooth mouth piece is extremely small, the yarn containing amount at the position is influenced, and the yarn is broken in the extrusion process. The application also needs to greatly change the corresponding needle selection mechanism, the cost is increased, and the universality is not strong.
