Description

Technical Field

[0001] The present invention relates to the technical field of circular knitting machine needles, and particularly relates to a knitting needle with a needle turning wing. Background Art

[0002] A circular knitting machine is a relatively common knitting device. Its most important functional part is the loop-forming system, which includes a needle cylinder. Needle grooves are provided on the needle cylinder, and knitting needles are placed in the needle grooves. The knitting needles are driven by cams to move along the needle grooves in the needle grooves to perform hole picking and loop gathering, so as to complete the process of needle turning and loop forming. At present, however, the circular knitting machine needles can only weave ordinary flat fabric and cannot produce a three-dimensional knitting effect of hole picking and loop gathering. Summary of the Invention

[0003] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0004] A knitting needle with a needle turning wing, comprising a needle hook, a needle neck, a needle body, a needle tongue, and a needle turning wing connected between the needle neck and the needle body. The needle turning wing is located on the left side of the needle neck and the needle body. The needle turning wing has a curved surface structure. The needle turning wing includes a horizontal base, a wing body, and a hooked wing tip. The horizontal base is trapezoidal and long strip-shaped with a groove on the right side. The wing body extends along the lower left side of the horizontal base and is S-shaped in the depth direction. The hooked wing tip extends along the left side of the wing body and bends inward downward.

[0005] Further, the longitudinal section of the hooked wing tip is a circular arc with an opening to the right.

[0006] Further, the acute front end of the horizontal base is connected to the top end of the end of the needle neck, and the other end of the horizontal base is connected to the top end of the front end of the needle body.

[0007] Further, one end of the needle tongue is rotatably connected to the needle neck, and the other end of the needle tongue overlaps with the needle hook.

[0008] Further, the wing body includes a convex arc section close to the horizontal base side and a concave arc section close to the wing tip side.

[0009] Further, the length of the needle turning wing gradually becomes smaller from the acute front end of the horizontal base to the direction of the hooked wing tip.

[0010] Further, the thickness of the needle turning wing gradually becomes smaller from the direction of the horizontal base to the end of the hooked wing tip.

[0011] Further, it further includes a needle shank, and the needle shank is formed at the rear end of the needle body.

[0012] Further, the needle hook, the needle neck, the needle body, the needle turning wing, and the needle shank are of an integrally formed structure.

[0013] The beneficial effects of the present invention are:

[0014] The present invention is stable and reliable, with a long service life, completely solving the problem of parallel needle turning in circular weft knitting machines. It can automatically turn the needles into loops, enabling circular weft knitting machines to be no longer limited to the weaving of ordinary flat knitted fabrics, and can automatically knit various patterns, improving production efficiency and the three-dimensional knitting effect of products.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] A knitting needle with a needle turning wing includes a needle hook 1, a needle neck 3, a needle body 4, a needle shank 6, a needle tongue 2, and a needle turning wing 5 connected between the needle neck 3 and the needle body 4. The needle shank 6 is formed at the rear end of the needle body 4. The needle turning wing 5 is located on the left side of the needle neck 3 and the needle body 4. The needle turning wing 5 has a curved surface structure. The needle turning wing 5 includes a horizontal base 51, a wing body 52, and a hook-shaped wing tip 53. The horizontal base 51 is trapezoidal and elongated with a groove on the right side. The acute front end of the horizontal base 51 is connected to the top end of the end of the needle neck 3, and the other end of the horizontal base 51 is connected to the top end of the front end of the needle body 4. The wing body 52 extends along the lower left side of the horizontal base 51 and is S-shaped in the depth direction. The hook-shaped wing tip 53 extends along the left side of the wing body 52 and bends downward and inward. The longitudinal section of the hook-shaped wing tip 53 is a circular arc with an opening to the right.

[0020] One end of the needle tongue 2 is rotatably connected to the needle neck 3, and the other end of the needle tongue 2 overlaps with the needle hook 1.

[0021] The wing body 52 includes a convex arc section 521 close to the horizontal base 51 and a concave arc section 522 close to the wing tip.

[0022] The length of the needle turning wing 5 gradually decreases from the acute front end of the horizontal base 51 towards the direction of the hook-shaped wing tip 53, and the thickness of the needle turning wing 5 gradually decreases from the direction of the horizontal base 51 towards the end of the hook-shaped wing tip 53. The horizontal base 51 is connected to the wing body 52, the needle neck 3, and the needle body 4 by arc transitions.

[0023] The needle hook 1, the needle neck 3, the needle body 4, the needle turning wing 5, and the needle shank 6 are of an integrally formed structure.

[0024] During the actual working process, after the coil 9 slides past the latch 2, it is put on the transfer needle wing 5 of the transfer knitting needle 7; then, as the receiving knitting needle 8 moves upward, the front part of its hook 1 gradually moves into the inner side of the curved surface of the transfer needle wing 5 on the transfer knitting needle 7 and enters the expanded coil 9; the hook 1 of the receiving knitting needle 8 passes through the coil 9 on the transfer needle wing 5, and at the same time, due to the curved surface structure of the transfer needle wing 5, the latch 2 of the receiving knitting needle 8 is automatically opened; finally, the coil 9 moves along the back of the latch 2 of the transfer knitting needle 7, the latch 2 of the transfer knitting needle 7 is closed, the coil 9 slides out of the head of the transfer knitting needle 7, and then the coil 9 on the transfer knitting needle 7 is located in the hook 1 of the receiving knitting needle 8, and the transfer is successful.
