With the above understanding of the components and the assembly of the present invention, please refer to fig. 4, fig. 5, fig. 6 and fig. 7, wherein fig. 5 is a schematic structural view of a first embodiment of a yarn feeding operation according to the present invention; FIG. 6 is a schematic view of the structure of FIG. 5 from another perspective; fig. 7 is a structural view showing the operation of the knitting needle of the first embodiment. As shown in fig. 4, the yarn feeding device 1 of the present invention is applied to a circular knitting machine 32, and the yarn feeding device 1 is provided on the side of a needle cylinder 322 of the circular knitting machine 32, and can feed a first yarn 34 and a second yarn 36 having different colors into the yarn feeding device 1. The first yarn 34 is guided into the first yarn feeding hole 162 of the yarn guide 16, and the first yarn 34 passes through the first yarn feeding hole 162 to the first yarn threading hole 242 of the first movable member 24, which is a yarn guide path; the second yarn 36 is guided into the second yarn feeding hole 164 of the creel 16, and the second yarn 36 is guided out of the second yarn threading hole 262 of the second movable member 26, which is a yarn guide path. Because the yarn position adjusting machine 12 and the yarn feeding body 10 are vertically arranged with an inclination angle, the knitting needle 38 of the circular knitting machine 32 is vertically arranged with the first movable member 24 and the second movable member 26, when the knitting needle 38 hooks the first yarn 34 and the second yarn 36, the relative angle position between the knitting needle 38 and the first movable member 24 and the second movable member 26 can be effectively shortened. In detail, the knitting needle 38 is operated by an up-and-down hook line to hook and draw the first yarn 34 and the second yarn 36, and the driving module 20 is used to drive the first movable member 24 and the second movable member 26 to perform a staggered operation, so that the path of the first yarn 34 and the second yarn 36 can be shortest by the knitting needle 38 via the yarn guiding path between the yarn position adjusting machine 12 and the yarn feeding body 10, and the included angle θ formed by the knitting needle 38 and the first yarn 34 and the second yarn 36 is relatively small, preferably designed to be smaller than 30 °. If only one of the first driving element 222 and the second driving element 224 controls the first movable member 24 or the second movable member 26 to move, the first movable member 24 and the second movable member 26 can also be displaced up and down. In the first embodiment, the first movable member 24 and the second movable member 26 perform reciprocating movement with vertical displacement at the same time; in detail, when the first driving element 222 controls the first movable member 24 to move downward, the second driving element 224 controls the second movable member 26 to move upward, so that the first movable member 24 and the second movable member 26 perform reciprocating movement in a vertically staggered manner, and when the first yarn 34 and the second yarn 36 are hooked by the knitting needle 38, the problems of yarn entanglement between the first yarn 34 and the second yarn 36 or yarn breakage due to hooking tension can be effectively avoided because the path is short and the included angle θ is small.
Besides the first yarn feeding hole 162 and the second yarn feeding hole 162, the yarn guiding frame 16 can add a new number of yarn feeding holes according to the manufacturing requirement, so as to allow different yarns, such as elastic yarns or functional yarns, to pass through the yarn guiding frame. Each feed hole provides a yarn to be fed into it, but the aperture of the first and second feed holes 242 and 262 is sufficient to provide at least one yarn penetration, which is simultaneously hooked by the knitting needle 38 for subsequent knitting operations, in response to the performance requirements of the fabric.
Referring to fig. 4, fig. 8, fig. 9 and fig. 10, fig. 8 is a schematic structural view of a yarn feeding operation according to a second embodiment of the present invention; FIG. 9 is a schematic view of the structure of FIG. 8 from another perspective; fig. 10 is a structural view showing the operation of the knitting needle of the first embodiment. In the second embodiment, the operation of the circular knitting machine 32 is controlled by using an electronic technology, the circular knitting machine 32 is coupled to the yarn position adjusting machine 12, and when the yarn position adjusting machine 12 receives the switching line control signal of the circular knitting machine 32, the driving module 22 switches and drives the first movable member and the second movable member to perform the staggered operation, so as to perform the yarn switching operation of the first yarn 34 and the second yarn 36, that is, to switch the first yarn 34 and the second yarn 36 with different colors to the positions in the knitting needle 38. The knitting needles 38 draw the first yarn 34 and the second yarn 36, and perform the upper and lower knitting operations to perform the subsequent fabric processing, as can be seen from the knitting needle operations of the first and second embodiments, in the second embodiment, the positions of the first yarn 34 and the second yarn 36 in the knitting needles 38 are reversed. In detail, when the first driving element 222 controls the first movable element 24 to move upward, the second driving element 224 controls the second movable element 26 to move downward, so that the first movable element 24 and the second movable element 26 perform reciprocating movement in a vertically staggered manner, so that when the first yarn 34 and the second yarn 36 are hooked by the knitting needle 38, the exchanged first yarn 34 and second yarn 36 can be simultaneously located on the same surface of the fabric, and different colors are presented. Therefore, the color expressive force that the same surface of the fabric has different colors can be achieved only by a thread exchanging way without changing yarns, so that the manufacturing cost can be reduced, and the design difficulty of the fabric in the prior art can be solved.
In summary, the present invention is provided to solve the problems and disadvantages of the prior art, and the key technology is that yarns with different colors can be simultaneously located on the same surface of the fabric by using the exchange thread manner without changing the yarns, so as to present different colors, thereby increasing the color expression of the fabric. Moreover, the two moving parts of the yarn position adjusting machine are used for dislocation operation, so that the relative angle position between the knitting needle and the two moving parts when the knitting needle hooks and pulls the two yarns can be effectively shortened, the fabric time course and the yarn feeding actuation stability are further shortened, the problems of yarn winding or yarn breaking and the like are solved, the time is saved, the manufacturing smoothness is improved, and the production efficiency can be effectively improved.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
