Problems solved by technology

[0004] However, if the existing loop transfer device is applied to high-density fabrics, the loop transfer reed will be trapped and pressed by the loop because the loop is small and when the loop is placed outside the loop transfer reed of the loop transfer needle. Flat, which makes it difficult for the corresponding knitting needle (regular needle) to insert into the transfer reed, so there are often situations where needles miss or collide with the transfer reed, resulting in the failure of the transfer action, which in turn causes fabric defects

[0027] see Figure 1 to Figure 3 , the present invention provides a high-density fabric transfer device, the transfer device is applied to high-density fabrics, the transfer device includes a regular needle 1, a transfer needle 2, a machine dial 3 and a needle cylinder 4, usually circular The mechanism of the main knitting part of the loom includes a plurality of regular needles 1 and a plurality of transfer needles 2, and only one regular needle 1 and a transfer needle 2 are disclosed in the figure. The machine dial 3 and the needle cylinder 4 are vertically arranged. The regular needle 1 is arranged on the machine dial 3, that is, the machine dial 3 is provided with a plurality of dial needle grooves (figure omitted), and the regular needle 1 is arranged in the corresponding dial needle groove, and Can move horizontally. The transfer needle 2 is arranged on the needle cylinder 4, that is to say, the needle cylinder 4 is provided with a plurality of needle cylinder needle g...

[0036] The present invention also provides a high-density fabric transfer method, comprising the following steps;

[0037] First of all, provide a transfer device (such as Figure 1 to Figure 3 As shown), the loop transfer device includes a regular needle 1, a loop transfer needle 2, a machine dial 3, a needle cylinder 4, a dial mountain angle 5 and a needle cylinder angle 6, etc.; since the circle transfer device is the same as the above-mentioned embodiment , so it will not be repeated;

[0038] Place the regular needle 1 and transfer needle 2 in a predetermined position (such as Figure 4 Shown), ready to move circle action;

[0039] Then promote this regular needle 1 to move forward, make the first yarn ring (old yarn ring) A push aside the first needle latch 13 (as Figure 5 shown), prepare to remove the second yarn ring (new yarn ring) B;

[0040] Then make this first yarn ring A stay in the first needle hook 12, and regular needle 1 is moved forward (as Image 6 Sh...

Abstract

The invention discloses a loop transfer device and method for high-density fabric. The loop transfer device for the high-density fabric comprises regular needles and loop transfer needles. The regular needles are arranged on a machine table needle dial in a horizontally moving mode; the loop transfer needles are arranged on a needle cylinder in a vertically moving mode; stitches of the regular needles are arranged in corresponding first rails in a matched mode; stitches of the loop transfer needles are arranged in corresponding second rails in a matched mode; two-section type loop transfer sections are arranged in the second rails, and the loop transfer needles can be guided to ascend by a small section in advance; one ends of the regular needles are slightly inserted into loop transfer reeds of the corresponding loop transfer needles, and then the loop transfer needles are pushed to the upper part for loop transfer. Therefore, missed stitch or collision of the loop transfer reeds can be avoided.

Description

technical field [0001] The invention relates to a loop transfer device and method for high-density fabrics, in particular to a loop transfer device and method for high-density fabrics that use loop transfer needles to move yarn loops. Background technique [0002] The mechanism of the main knitting part of the existing circular loom includes a plurality of upper knitting needles and a plurality of lower knitting needles. The upper knitting needles can move horizontally and are set on the dial of the machine table, and the lower knitting needles can move vertically and are set on the needle cylinder. On top, the upper knitting needle and the lower knitting needle are used to produce inner, outer, up and down displacements respectively, so as to carry out the action of needle exit and retraction, and knitting yarn after hooking yarn, repeating this action to achieve the function of knitting. [0003] High-density fabrics have been used to move yarn loops with transfer devices ...
