[0039] Reference Figure 1-Figure 8 A double-drive anti-tangling yarn feeding device comprises a transmission box 1, a yarn guide assembly 2 and a driving component 3, wherein the driving component 3 is arranged on one side of the transmission box 1, and the yarn guide assembly 2 is arranged on a side of the transmission box 1 away from the driving component 3, and the yarn guide assembly 2 is used to transmit the yarn;

[0040] The yarn guide assembly 2 includes a yarn passing plate 21 and a yarn roller component 22, and the yarn roller component 22 includes a first yarn guide roller 221 and a second yarn guide roller 222. The first yarn guide roller 221 and the second yarn guide roller 222 are spaced apart and distributed on one side of the transmission box 1. The outer peripheral surfaces of the first yarn guide roller 221 and the second yarn guide roller 222 are each provided with a plurality of anti-knot paths 223 for placing yarns. The plurality of anti-knot paths 223 are equally spaced and distributed to limit the position of the yarns on the first yarn guide roller 221 and the second yarn guide roller 222. , so that the yarns are equally spaced on the first yarn guide roller 221 and the second yarn guide roller 222, and are not easily entangled. The yarn passing plate 21 is provided with two groups, one group is located above the first yarn guide roller 221, and forms a yarn feeding end with the first yarn guide roller 221, and the other group is located below the second yarn guide roller 222, and forms a yarn outlet end with the second yarn guide roller 222. When the yarn enters from the yarn feeding end and exits from the yarn outlet end, it can effectively avoid the phenomenon that the path overlap during the yarn feeding process will easily cause entanglement;

[0041] The driving component 3 includes a first driving motor 31 and a second driving motor 32. The first driving motor 31 is connected to the first yarn guide roller 221 through a coupling, so that the first yarn guide roller 221 can rotate counterclockwise. The second driving motor 32 is connected to the second yarn guide roller 222, so that the second yarn guide roller 222 can rotate clockwise. Through the simultaneous operation of the two groups of motors, a slight pulling force is generated during the yarn feeding process to adjust the yarn tension, so that the yarn can be taut on the anti-knot channel 223 to avoid the yarn from deflecting during the movement. The first driving motor 31 and the second driving motor 32 both adopt servo driving motors in the prior art.

[0042] Based on the above structure, since the outer peripheral surfaces of the first yarn guide roller 221 and the second yarn guide roller 222 are respectively provided with a plurality of anti-knot paths 223 at equal intervals, and the yarn passing plate 21 respectively forms a yarn inlet end and a yarn outlet end with the first yarn guide roller 221 and the second yarn guide roller 222, the yarn is passed through the yarn passing plate 21 at the yarn inlet end, and is respectively hung on the anti-knot paths 223 of the first yarn guide roller 221 and the second yarn guide roller 222, one end of the yarn extends to the position of the yarn outlet end, and thus passes through the yarn passing plate 21 at the yarn outlet end, thereby completing Regarding the placement of the yarn, when the placement is completed, the first drive motor 31 and the second drive motor 32 are started, thereby driving the first yarn guide roller 221 to rotate counterclockwise and driving the second yarn guide roller 222 to rotate clockwise, thereby driving the yarn to flow. Since the yarn is separated on the first yarn guide roller 221 and the second yarn guide roller 222, the phenomenon of entanglement during the yarn feeding process is effectively avoided, and the problem that the entanglement will cause the yarn to form lumps or agglomerates on the yarn feeder, which will hinder the normal flow of the yarn, is solved.

[0043] In one embodiment, referring to Figure 1-Figure 3 , Figure 7 and Figure 8 The yarn guide assembly 2 also includes a yarn transfer plate 23, which is located between the first yarn guide roller 221 and the second yarn guide roller 222, and one end of the yarn transfer plate 23 is fixed on the transmission box 1. When the yarn passes through the yarn transfer plate 23, the yarn can be limited to prevent the yarn from deviating from the anti-knot path 223 and causing entanglement when the first yarn guide roller 221 and the second yarn guide roller 222 rotate too fast.

[0044] In one embodiment, referring to Figure 1-Figure 5 and Figure 7 , and also includes several U-shaped slot blocks 4, the concave side of the U-shaped slot block 4 has a magnetic pole 41 and is provided with several equally spaced notches 42, the middle end of the yarn passing plate 21 is a T-shaped structure, and the yarn passing plate 21 and the yarn transfer plate 23 are provided with several equally spaced open slots 24, and the inner sides of the open slots 24 and the notches 42 are both semicircular structures. By embedding several U-shaped slot blocks 4 into the yarn passing plate 21 and the yarn transfer plate 23, the limiting yarn hole 6 formed between the notches 42 and the open slots 24 is a circular structure. Since there are no edges and corners inside the circular structure and the interior is smooth, the yarn is prevented from breaking during the yarn feeding process. The yarn passing plate 21 and the yarn transfer plate 23 are made of magnetic material, and are magnetically connected to the yarn passing plate 21 and the yarn transfer plate 23 through the magnetic pole 41. Through the magnetic connection, during the yarn feeding process, the yarn is not easy to be displaced in the limiting yarn hole 6, and it is convenient for the use and disassembly of the yarn.

[0045] In one embodiment, referring to Figure 1 , Figure 3 , Figure 7 and Figure 8 , also includes a connecting plate 5 and a fastener 7. The other ends of the first yarn guide roller 221 and the second yarn guide roller 222 are rotatably connected to the connecting plate 5 through the fastener 7. The yarn feeding plate 23 is fixed between the transmission box 1 and the connecting plate 5. The setting of the connecting plate 5 can effectively prevent the first yarn guide roller 221 and the second yarn guide roller 222 from shaking when rotating, thereby further improving the stability during yarn feeding.

[0046] In one embodiment, referring to Figure 3 , Figure 6 and Figure 8 A mounting seat 11 is also provided at the bottom of the transmission box 1. The mounting seat 11 is a U-shaped structure. When the yarn is sent, the transmission box 1 is fixed on the yarn frame, which is not easy to shake, and the stability of the yarn is further improved.

[0047] In one embodiment, referring to Figure 6, and also includes a control switch 8, which is arranged on one side of the transmission box 1 and on the same plane as the driving component 3. The control switch 8 is used to be electrically connected to the first driving motor 31 and the second driving motor 32. When the control switch 8 is started, the operator can change the operating speed of the driving component 3 through the control switch 8, making the operation more convenient.
