[0037] Embodiment 1

[0038] Based on the market demand for multi-color cord embroidery, on the basis of the existing single-color cord embroidery device on the market, Figures 1 to 7 As shown, a rope embroidery device capable of realizing a multi-color rope embroidery function is designed, which includes a rope embroidery bracket 100, on which at least two-color (individual) loop heads are provided, a rope swing driving component for driving the at least two-color loop heads to swing, and at least two-color rope embroidery components corresponding to the at least two-color loop heads are arranged.

[0039] Each color rope embroidery component conveys a corresponding color rope to each color loop head and keeps the rope passing through the loop head in a straight state. The swing rope drive component is provided with a swing rope drive motor 8. A swing rope transmission mechanism is provided between the swing rope drive motor 8 and the at least two color loop heads to drive the at least two color loop heads to swing.

[0040] Therefore, the above technical solution can realize multi-color rope embroidery, solve the disadvantage that traditional rope embroidery can only embroider ropes of one color, enrich the types of embroidery products, and meet the market demand for multi-color rope embroidery. In addition, only one swing rope driving motor is required to drive all color loop heads to swing. It is avoided that each color loop head is driven by a swing rope driving motor, and more color loop heads can be driven to swing ropes in a limited space.

[0041] In this embodiment, three-color rope embroidery is taken as an example for explanation, and three-color loop heads are provided accordingly, namely, a first-color loop head 21, a second-color loop head 22, and a third-color loop head 23. The structure of the loop head refers to the prior art, and is an annular body, with a central through hole for the embroidery needle to pass through, and a rope threading hole 201 is provided on the circumferential outer side of the central through hole. Correspondingly, a first-color rope threading hole is provided on the first-color loop head for the first-color rope to pass through, a second-color rope threading hole is provided on the second-color loop head for the second-color rope to pass through, and a third-color rope threading hole is provided on the third-color loop head for the third-color rope to pass through.

[0042] Corresponding to the three-color looping head, a three-color rope embroidery component is set, namely a first-color rope embroidery component, a second-color rope embroidery component, and a third-color rope embroidery component, and the first-color rope embroidery component, the second-color rope embroidery component, and the third-color rope embroidery component have the same structure.

[0043] Referring to the single-color rope embroidery device in the prior art, the first-color rope embroidery component is provided with a first-color rope collection and release mechanism, a first rope passing spring 4, and a first-color swing rope tightening mechanism. The first-color rope collection and release mechanism is usually provided with two rope collection and release wheels to clamp the rope for collection and release, and one of the rope collection and release wheels is driven to rotate by a motor. That is, the first-color rope collection and release mechanism is correspondingly provided with a first rope collection and release motor 1 and a first rope collection and release wheel group 1a. The first-color swing rope tightening mechanism pulls the first-color rope when the first-color looping head rotates, so that the first-color rope is in a straight state at the first-color looping head. The first-color rope is introduced from the entrance of the first rope collection and release wheel group, passes through the first rope passing spring 4, passes through the first-color swing rope tightening mechanism, and finally passes through the rope threading hole of the first-color looping head. The first-color swing rope tightening mechanism includes a first-color rope passing frame 17 movably connected to the rope embroidery bracket and a first swing rope spring 18 connected between the rope embroidery bracket and the first-color rope passing frame 17. The first color rope passing frame is provided with a rope passing swing rod, one end of which is connected with a pin shaft, which is installed on the rope embroidery bracket, and the other end of which is connected with a rope passing ring, through which the rope passes. The first rope swing spring 18 is a torsion spring, which drives the first color rope passing frame to twist and tighten the rope.

[0044] The structure is the same as that of the first color rope embroidery component, wherein the second color rope embroidery component is provided with a second color rope collection and release mechanism, a second rope passing spring 5, and a second color swing rope tensioning mechanism. The second color rope collection and release mechanism is correspondingly provided with a second rope collection and release motor 2 and a second rope collection and release pulley group 2b. A second rope passing spring 5 is correspondingly provided below the second color rope collection and release mechanism, and the second color swing rope tensioning mechanism includes a second color rope passing rope frame 15 movably connected to the rope embroidery bracket and a second swing rope spring 16 connected between the rope embroidery bracket and the second color rope passing rope frame. The third color rope embroidery component is provided with a third color rope collection and release mechanism, a third rope passing spring 6, and a third color swing rope tensioning mechanism. The third color rope collection and release mechanism is correspondingly provided with a third rope collection and release motor 3 and a third rope collection and release pulley group 3c. A third rope passing spring 6 is correspondingly provided below the third color rope collection and release mechanism, and the third color swing rope tensioning mechanism includes a third color rope passing rope frame 10 movably connected to the rope embroidery bracket and a third swing rope spring 11 connected between the rope embroidery bracket and the third color rope passing rope frame.

[0045] Of course, according to the needs of rope passing, a fourth rope passing spring 9, a fifth rope passing spring 12, a sixth rope passing spring 13, a seventh rope passing spring 14 and a rope guide hole 19 may also be provided.

[0046] The first color rope is sent out from the first rope retracting and releasing pulley group 1a, and passes through the first rope passing spring 4, the sixth rope passing spring 13, the first color rope passing frame 17 and the rope threading hole on the first color looping head 21 in sequence. The second color rope is sent out from the second rope retracting and releasing pulley group 2b, and passes through the second rope passing spring 5, the fifth rope passing spring 12, the second color rope passing frame 15 and the rope threading hole on the second color looping head 22 in sequence. The third color rope is sent out from the third rope retracting and releasing pulley group 3c, and passes through the third rope passing spring 6, the fourth rope passing spring 9, the third color rope passing frame 10, the seventh rope passing spring 14, the rope guide hole 19 and the rope threading hole on the third color looping head 23 in sequence.

[0047] Referring to the prior art, such as Figure 1 As shown, the above-mentioned cord embroidery device is installed on the embroidery machine head 4, that is, a cord embroidery machine head is formed. Correspondingly, the cord embroidery machine includes one or more embroidery machine heads 4, and the embroidery machine head is a common flat embroidery machine head, and the embroidery machine head includes a head housing 41 and a needle bar frame 42 slidably mounted on the head housing, and a row of needle bars is provided on the needle bar frame 42, and embroidery needles are correspondingly provided. In this embodiment, No. 1 needle 401, No. 2 needle 402, and No. 3 needle 403 are provided. The above-mentioned cord embroidery device is installed on the side of the needle bar frame.

[0048] Since the cord embroidery bracket 100 is fixedly mounted on the side of the needle bar rack, the loop head needs to be correspondingly arranged below the embroidery needle. Therefore, a loop seat 20 extending to the side is provided at the bottom of the cord embroidery bracket, and the loop seat needs to extend directly in front of the needle bar rack to correspond to being located below the embroidery needle. All color loop heads are rotatably connected to the loop seat 20 and are arranged side by side on the loop seat. The spacing between two adjacent color loop heads is fixed, and in this embodiment, the spacing between two adjacent color loop heads is equal to the spacing between two needle bars on the corresponding embroidery machine head. Still taking the three-color cord embroidery as an example, a first color loop head 21, a second color loop head 22, and a third color loop head 23 are arranged in sequence from front to back along the extension direction of the loop seat.

[0049] In this embodiment, the swing rope transmission mechanism is provided with a swing rope color changing structure, and the swing rope driving motor 8 drives the first color looping head 21, the second color looping head 22, and the third color looping head 23 correspondingly through color changing.

[0050] The swing rope color-changing structure is provided with a color-changing gear shaft, a color-changing gear 26 arranged on the color-changing gear shaft, a color-changing gear shaft, at least two color-changing gears rotatably connected to the color-changing gear shaft, and a color-changing motor 7 that drives the color-changing gear to move axially relative to the at least two color-changing gears to change colors, and the color-changing gear shaft is driven by a swing rope driving motor 8. The color-changing gear shaft and the color-changing gear shaft are both arranged vertically.

[0051] Still taking the three-color rope embroidery as an example, there are three corresponding color-changing gears, which are the first color-changing gear 27, the second color-changing gear 28, and the third color-changing gear 29 from top to bottom, which correspondingly drive the third color loop head 23, the first color loop head 21, and the second color loop head 22.

[0052] In order to guide the overall axial movement of the color-changing gear shaft and the color-changing gear 26, the swing rope color-changing structure is also provided with a color-changing guide rail assembly 24, which includes a color-changing guide rail and a color-changing slider that slides linearly along the color-changing guide rail. The color-changing gear 26 is fixed to the color-changing gear shaft, and the color-changing gear shaft is rotatably supported on the color-changing slider through a bearing. The color-changing motor is connected to a lead screw nut assembly 23, which includes a lead screw and a nut threadedly connected to the lead screw. The nut is connected to the color-changing slider, and the nut cannot rotate. Therefore, when the lead screw rotates, the nut is driven to move linearly along the lead screw, and the nut drives the color-changing slider and the color-changing gear thereon to move linearly.

[0053] The color-changing gear shaft is driven by the swing rope driving motor 8, and the color-changing gear 26 is driven to rotate. Since the color-changing gear and the color-changing gear shaft need to move axially relative to the output shaft of the swing rope driving motor 8 when changing colors, a movable connection structure is provided between the output shaft of the swing rope driving motor and the color-changing gear shaft. The movable connection structure allows the color-changing gear shaft to move axially and maintains the transmission relationship between the output shaft of the swing rope driving motor and the color-changing gear shaft after the color-changing gear shaft moves axially.

[0054] As an embodiment, the movable connection structure is a spline connection structure 25, including a spline groove connected to the output shaft and a spline gear provided on the color-changing gear shaft, the spline gear and the spline groove are meshed for transmission, the spline gear and the spline groove can move axially relative to each other, and the transmission relationship is still maintained after the color is changed. Of course, it can be understood that the spline connection structure 25 can also be replaced by a flat key connection structure or other structures with similar functions.

[0055] The advantage of belt transmission is that it is stable and reliable, and can also transmit power from the side of the embroidery machine head to the looping head in front of the embroidery machine through the bending of the transmission belt. In order to realize the transmission connection between the color-changing gear and the looping head, the color-changing gear is connected in parallel with a color-changing synchronous pulley, and the color-changing synchronous pulley is connected to the looping head through a synchronous belt. The looping head can be integrally provided with a pulley, and the color-changing gear and the color-changing synchronous pulley can be integrally provided.

[0056] Wherein, the first color looping head is provided with a first color looping head driving pulley 211 on the side, a first color driving synchronous belt is provided between the first color looping head driving pulley and the first color looping head, and a first color transmission synchronous belt is connected between the first color looping head driving pulley 211 and the first color change color synchronous belt pulley. The second color looping head is provided with a second color looping head driving pulley 221 on the side, a second color driving synchronous belt is provided between the second color looping head driving pulley and the second color looping head, and a second color transmission synchronous belt is connected between the second color looping head driving pulley and the second color change color synchronous belt pulley. The third color looping head is provided with a third color looping head driving pulley 231 on the side, a third color driving synchronous belt is provided between the third color looping head driving pulley and the third color looping head, and a third color transmission synchronous belt is connected between the third color looping head driving pulley and the third color change color synchronous belt pulley.

[0057] The design of the above-mentioned swing rope transmission mechanism, without increasing the space occupied, by adding a transmission pulley, etc., on the basis of the original single-color function, through ingenious design, solves the problem of being unable to break through the multi-color rope embroidery device due to the small needle bar spacing. A rope embroidery device that can realize the multi-color rope embroidery function is designed to better meet market demand.

[0058] Referring to the color change of ordinary flat embroidery, the needle bar frame slides horizontally along the machine head housing to change colors. The rope embroidery device is installed on the machine head housing of the embroidery machine. In this embodiment, the first color loop head 21, the second color loop head 22, and the third color loop head 23 are correspondingly located below the No. 1 needle 401, the No. 2 needle 402, and the No. 3 needle 403, and their positions are relatively fixed.

[0059] like Figure 5 As shown, when the rope embroidery function is started, needle No. 3 works. When the embroidery machine starts to embroider, the embroidery machine frame moves to the negative direction of Y, and the third color looping head 23 starts to work. The rope threading hole will carry the rope in the positive direction of the Y axis and swing to the left and right sides of the Y axis. The rope will be swung under the embroidery needle and fixed to the embroidery fabric by the embroidery thread. As the frame moves, more rope will be sent out by the third retractable rope wheel group 3c. The third color rope passes through the rope frame 10 under the tension of the third swing rope spring 11 to ensure that the rope in the rope threading hole of the third color looping head 23 is always in a straight state when it swings left and right, so as to ensure that the rope embroidered on the fabric has beautiful flat stitches.

[0060] When the pattern design requires working in other directions, the same principle applies.

[0061] When the third color work is completed and the second color rope embroidery is needed, the embroidery machine needle bar frame is switched to the next rope embroidery color, that is, needle No. 2 is working. At this time, the rope swing color changing structure changes the color, and the color changing gear 26 drives the third color changing gear 29 to start the No. 2 color rope embroidery work. Its working principle is the same as that of the third color.

[0062] Similarly, if the first color rope embroidery is needed, the embroidery machine needle bar frame continues to move and switches to the next rope embroidery color, that is, needle No. 1 works, and then the rope color changing structure is swung to change the color, and the color changing gear 26 drives the second color changing gear 28, and the embroidery work of the first color rope embroidery can be carried out.

[0063] Therefore, the function of embroidering three-color rope embroidery is realized.

[0064] Embodiment 2

[0065] like Figure 8 As shown, the difference from the first embodiment is that the color-changing structure is not provided in this embodiment, and the original color-changing gear set is replaced by a total transmission synchronous belt wheel 34. That is, the swing rope drive assembly is provided with a total transmission synchronous belt wheel 34, and the total transmission synchronous belt wheel 34 drives all color loop heads to rotate simultaneously through the synchronous belt. In this way, when the three-color rope embroidery device is working, the swing rope drive motor 8 drives the total transmission synchronous belt wheel 34, and the total transmission synchronous belt wheel 34 drives the first color loop head 21, the second color loop head 22, and the third color loop head 23 to swing and work under the embroidery needle through the corresponding synchronous belts.

[0066] Because when the embroidery machine is embroidering, each head (embroidery machine head) can only work at one needle position at a time. In this way, although the three loop heads swing together under the needle, only one of the loop heads works with the embroidery needle at the corresponding working needle position, and the other loop heads just idle (swing). Figure 1 As shown, when needle No. 3 403 is working, the rope on the corresponding third color loop head is embroidered on the fabric. Although the other two loop heads are also swinging, because the embroidery needles at the corresponding needle positions are not embroidered, they are just swinging in vain. Ropes not needed for the embroidery plate design will not be embroidered on the fabric, and the embroidery will not be affected. When it is necessary to embroider a rope of another color, the needle bar rack only needs to change color to another working needle position.

[0067] Specifically, the output shaft of the swing rope driving motor is connected to a transmission synchronous pulley 1 31, the total transmission synchronous pulley 34 is fixed to the total transmission synchronous pulley shaft, the total transmission synchronous pulley shaft is provided with a transmission synchronous pulley 2 32, and a transmission synchronous belt 33 is connected between the transmission synchronous pulley 1 31 and the transmission synchronous pulley 2 32. A first color looping head driving pulley 211 is provided on the side of the first color looping head, a first color driving synchronous belt is provided between the first color looping head driving pulley and the first color looping head, and a first color transmission synchronous belt is connected between the first color looping head driving pulley and the total transmission synchronous pulley 34. A second color looping head driving pulley 221 is provided on the side of the second color looping head, a second color driving synchronous belt is provided between the second color looping head driving pulley and the second color looping head, and a second color transmission synchronous belt is connected between the second color looping head driving pulley and the total transmission synchronous pulley 34; a third color looping head driving pulley 231 is provided on the side of the total transmission synchronous pulley, a third color driving synchronous belt is provided between the third color looping head driving pulley and the third color looping head, and a third color transmission synchronous belt is connected between the third color looping head driving pulley and the total transmission synchronous pulley 34.

[0068] It is understandable that in order to achieve more colorful rope embroidery, a fourth color rope embroidery component, or more, can also be set, and its structure and working principle refer to the three-color rope embroidery device in the above embodiment.

[0069] The above is only a specific embodiment of the invention, but the protection scope of the invention is not limited thereto. Those skilled in the art should understand that the invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
