[0038] Embodiment one

[0039] Based on the market demand for multi-color rope embroidery, on the basis of the single-color rope embroidery device in the market, referring to the structure of the single-color rope embroidery device in the market, a rope embroidery device capable of realizing multi-color rope embroidery is designed, as shown in the drawings, which comprises a rope embroidery support 100, at least two color (one) ring head is arranged on the rope embroidery support 100, a rope swinging driving assembly for driving the swing of the at least two color ring head, and at least two color rope embroidery assemblies corresponding to the at least two color ring head. Figures 1 to 7

[0040] Each color rope embroidery assembly corresponds to each color ring head to deliver corresponding color rope and make the rope passing through the ring head in a straight state, the rope swinging driving assembly is provided with a rope swinging driving motor 8, and a rope swinging transmission mechanism is arranged between the rope swinging driving motor 8 and the at least two color ring head to drive the swing of the at least two color ring head.

[0041] Therefore, the above technical scheme can realize multi-color rope embroidery, solve the problem that the traditional rope embroidery can only embroider one color rope, enrich the types of embroidery products, and meet the market demand for multi-color rope embroidery. Moreover, only one rope swinging driving motor is needed to drive all color ring heads to swing. Avoiding setting a rope swinging driving motor for each color ring head to drive, more color ring heads can be driven in limited space.

[0042] In this embodiment, three-color rope embroidery is taken as an example for description, and three-color ring heads are correspondingly arranged, i.e. a first color ring head 21, a second color ring head 22 and a third color ring head 23. The structure of the ring head refers to the prior art, which is a ring body with a central through hole for the embroidery needle to pass through, and a rope passing hole 201 is arranged on the outer side of the central through hole in the circumferential direction. A first color rope passing hole is arranged on the first color ring head for the first color rope to pass through, a second color rope passing hole is arranged on the second color ring head for the second color rope to pass through, and a third color rope passing hole is arranged on the third color ring head for the third color rope to pass through.

[0043] Three-color rope embroidery assemblies are arranged corresponding to the three-color ring heads, i.e. a first color rope embroidery assembly, a second color rope embroidery assembly and a third color rope embroidery assembly, and the structures of the first color rope embroidery assembly, the second color rope embroidery assembly and the third color rope embroidery assembly are the same.

[0044] ​Referring to the single color rope embroidery device in the prior art, the first color rope embroidery assembly is provided with a first color take-up and pay-off mechanism, a first rope passing spring 4 and a first color rope tensioning mechanism. The first color take-up and pay-off mechanism usually provides two take-up and pay-off wheels to hold and take up and pay off the rope, one of which is driven to rotate by a motor. That is, the first color take-up and pay-off mechanism is provided with a first take-up and pay-off motor 1 and a first take-up and pay-off wheel set 1a. The first color rope tensioning mechanism pulls the first color rope when the first color ring beating head rotates, so that the first color rope is in a straightened state at the first color ring beating head. The first color rope is introduced into the first take-up and pay-off wheel set, passes through the first rope passing spring 4, then passes through the first color rope tensioning mechanism, and finally passes into the rope passing hole of the first color ring beating head. The first color rope tensioning mechanism includes a first color rope passing frame 17 movably connected to the rope embroidery support and a first rope tensioning spring 18 connected between the rope embroidery support 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 the rope passing swing rod is connected with a pin shaft, the pin shaft is installed on the rope embroidery support, the other end of the rope passing swing rod is connected with a rope passing ring, and the rope passes through the rope passing ring. The first rope tensioning spring 18 is a torsion spring, which drives the first color rope passing frame to twist and tighten the rope.

[0045] The structure of the first color rope embroidery assembly is the same, wherein the second color rope embroidery assembly is provided with a second color take-up and pay-off mechanism, a second rope passing spring 5 and a second color rope tensioning mechanism. The second color take-up and pay-off mechanism is provided with a second take-up and pay-off motor 2 and a second take-up and pay-off wheel set 2b. The second rope passing spring 5 is arranged below the second color take-up and pay-off mechanism, and the second color rope tensioning mechanism includes a second color rope passing frame 15 movably connected to the rope embroidery support and a second rope tensioning spring 16 connected between the rope embroidery support and the second color rope passing frame. The third color rope embroidery assembly is provided with a third color take-up and pay-off mechanism, a third rope passing spring 6 and a third color rope tensioning mechanism. The third color take-up and pay-off mechanism is provided with a third take-up and pay-off motor 3 and a third take-up and pay-off wheel set 3c. The third rope passing spring 6 is arranged below the third color take-up and pay-off mechanism, and the third color rope tensioning mechanism includes a third color rope passing frame 10 movably connected to the rope embroidery support and a third rope tensioning spring 11 connected between the rope embroidery support and the third color rope passing frame.

[0046] Of course, according to the need for 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 can also be provided.

[0047] The first color rope is sent out from the first rope winding and unwinding wheel set 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 threading hole on the first color ring beating head 21 in sequence. The second color rope is sent out from the second rope winding and unwinding wheel set 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 threading hole on the second color ring beating head 22 in sequence. The third color rope is sent out from the third rope winding and unwinding wheel set 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 guide rope hole 19 and the threading hole on the third color ring beating head 23 in sequence.

[0048] As shown in the prior art, Figure 1 The rope embroidery device is installed on the embroidery machine head 4 to form a rope embroidery embroidery machine head. Correspondingly, the rope embroidery embroidery machine comprises one or more embroidery machine heads 4, and the embroidery machine head is a common flat embroidery machine head. The embroidery machine head comprises a head shell 41 and a needle bar frame 42 slidably installed on the head shell. A row of needle bars is arranged on the needle bar frame, and embroidery needles are arranged correspondingly. In this embodiment, No. 1 needle 401, No. 2 needle 402 and No. 3 needle 403 are arranged.

[0049] Since the rope embroidery support 100 is fixedly installed on the side surface of the needle bar frame, the ring beating head needs to be arranged below the embroidery needle. Therefore, the bottom of the rope embroidery support is provided with a ring beating seat 20 extending to the side surface. The ring beating seat needs to extend to the front of the needle bar frame to correspond to the position below the embroidery needle. All color ring beating heads are rotationally connected to the ring beating seat 20 and arranged side by side on the ring beating seat. The distance between adjacent two color ring beating heads is fixed, and in this embodiment, the distance between adjacent two color ring beating heads is equal to the distance between two needle bars on the corresponding embroidery machine head. Taking three-color rope embroidery as an example, the first color ring beating head 21, the second color ring beating head 22 and the third color ring beating head 23 are arranged in sequence from front to back along the extension direction of the ring beating seat.

[0050] In this embodiment, the rope swinging transmission mechanism is provided with a rope swinging color changing structure. The rope swinging driving motor 8 drives the first color ring beating head 21, the second color ring beating head 22 and the third color ring beating head 23 through color changing.

[0051] The rope swinging 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 rotationally connected to the color changing gear shaft, and a color changing motor 7 driving the color changing gear to move axially relative to the at least two color changing gears to change color. The color changing gear shaft is driven by the rope swinging driving motor 8. The color changing gear shaft and the color changing gear shaft are both arranged vertically.

[0052] Taking the three-color rope embroidery as an example, there are three 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, respectively, which drive the third color ring head 23, the first color ring head 21, and the second color ring head 22.

[0053] To guide the overall axial movement of the color-changing gear shaft and the color-changing gear 26, the swing rope color-changing structure also includes a color-changing guide rail assembly 24. The color-changing guide rail assembly 24 includes a color-changing guide rail and a color-changing slider that slides linearly along the guide rail. The color-changing gear 26 is fixed to the color-changing gear shaft, which is rotatably supported on the color-changing slider via bearings. The color-changing motor is connected to a lead screw and nut assembly 23. This assembly includes a lead screw and a nut threadedly connected to it. The nut is connected to the color-changing slider and cannot rotate. Therefore, when the lead screw rotates, it drives the nut to move linearly along the lead screw, which in turn drives the color-changing slider and its color-changing gear to move linearly.

[0054] The color-changing gear shaft is driven by the oscillating rope drive motor 8, which in turn drives the color-changing gear 26 to rotate. Since the color-changing gear and its shaft need to move axially relative to the output shaft of the oscillating rope drive motor 8 during color changing, a movable connection structure is provided between the output shaft of the oscillating rope drive motor and the color-changing gear shaft. This movable connection structure allows the color-changing gear shaft to move axially and maintains the transmission relationship between the output shaft of the oscillating rope drive motor and the color-changing gear shaft even after the axial movement of the color-changing gear shaft.

[0055] In one embodiment, the movable connection structure is a spline connection structure 25, including a spline groove connected to the output shaft and a spline gear disposed on the color-changing gear shaft. The spline gear meshes with the spline groove for transmission, and the spline gear and spline groove can move axially relative to each other, maintaining the transmission relationship after color change. Of course, it is understood that the spline connection structure 25 can also be replaced by a flat key connection structure or other structures with similar functions.

[0056] The advantage of belt drive lies in its stability and reliability. It can also transmit power from the side of the embroidery machine head to the loop-forming head at the front of the machine through the bending of the belt. To achieve the transmission connection between the color-changing gear and the loop-forming head, the color-changing gear is connected side-by-side with a color-changing synchronous pulley, which is then connected to the loop-forming head via a synchronous belt. The loop-forming head can have a pulley integrated into its design, and the color-changing gear and the color-changing synchronous pulley can also be integrated into one unit.

[0057] The side of the first color beating ring head is provided with a first color beating ring head driving pulley 211, a first color driving synchronous belt is arranged between the first color beating ring head driving pulley and the first color beating ring head, and a first color transmission synchronous belt is connected between the first color beating ring head driving pulley 211 and the first color variable-color synchronous pulley. The side of the second color beating ring head is provided with a second color beating ring head driving pulley 221, a second color driving synchronous belt is arranged between the second color beating ring head driving pulley and the second color beating ring head, and a second color transmission synchronous belt is connected between the second color beating ring head driving pulley and the second color variable-color synchronous pulley. The side of the third color beating ring head is provided with a third color beating ring head driving pulley 231, a third color driving synchronous belt is arranged between the third color beating ring head driving pulley and the third color beating ring head, and a third color transmission synchronous belt is connected between the third color beating ring head driving pulley and the third color variable-color synchronous pulley.

[0058] The design of the above-mentioned rope transmission mechanism solves the problem that the distance between the needle bars is small and the multi-color rope embroidery device cannot be broken through without increasing the space occupation by increasing the transmission pulley and the like on the basis of the original single-color function, and a rope embroidery device capable of realizing multi-color rope embroidery function is designed to better meet the market demand.

[0059] With reference to the color changing of ordinary flat embroidery, the needle bar frame slides transversely along the machine head shell to change color. The rope embroidery device is installed on the embroidery machine head shell, and in the embodiment, the first color beating ring head 21, the second color beating ring head 22 and the third color beating ring head 23 are located below the No. 1 needle 401, the No. 2 needle 402 and the No. 3 needle 403 respectively and are fixed in position.

[0060] As shown in the drawings, Figure 5 When the embroidery machine starts to embroider, the No. 3 needle works, and when the embroidery machine frame moves in the Y negative direction, the third color beating ring head 23 starts to work, the rope hole carries the rope in the positive direction of the Y axis and swings left and right to swing the rope under the embroidery needle, and the embroidery thread fixes the rope on the embroidery fabric. With the movement of the frame, more rope is sent out by the third rope winding and unwinding wheel set 3c, and the third color rope passes through the rope holder 10 under the tension of the third rope swinging spring 11 to ensure that the rope in the rope hole of the third color beating ring head 23 is always straight to ensure that the embroidery on the fabric is flat and beautiful.

[0061] When the pattern design needs to work in other directions, the same principle applies.

[0062] When the third color work is completed and the second color rope embroidery is needed, the embroidery machine needle bar frame changes to the next rope embroidery color, i.e. the No. 2 needle works, and at this time the rope color changing structure changes color, the color changing gear 26 drives the third variable-color gear 29 to start the No. 2 color rope embroidery work, and the working principle is the same as that of the third color.

[0063] Similarly, if the 1st color rope embroidery is needed, the needle bar frame of the embroidery machine continues to move, and the next rope embroidery color is changed, i.e., the 1st needle works, and then the rope changing structure changes the color, the second color changing gear 28 is driven by the color changing gear 26, and the 1st color rope embroidery can be performed.

[0064] Therefore, the three-color rope embroidery function can be realized.

[0065] Embodiment Two

[0066] As shown in Figure 8 , the difference between the embodiment and the embodiment one is that the color changing structure is not provided in the embodiment, and the original color changing gear set is replaced by a total transmission synchronous pulley 34. That is, the rope swinging driving assembly is provided with the total transmission synchronous pulley 34, and the total transmission synchronous pulley 34 drives all the color ring beating heads to rotate through the synchronous belts. In this way, when the three-color rope embroidery device works, the rope swinging driving motor 8 drives the total transmission synchronous pulley 34, and the total transmission synchronous pulley 34 drives the first color ring beating head 21, the second color ring beating head 22, and the third color ring beating head 23 to swing under the embroidery needle at the same time through the corresponding synchronous belts.

[0067] Because the embroidery machine can only work one needle position at a time, although the three ring beating heads swing together under the needle, only one ring beating head works with the corresponding embroidery needle, and the other ring beating heads are only idling (swing). As shown in Figure 1 , when the 3rd needle 403 works, the rope on the corresponding third color ring beating head is embroidered on the fabric, although the other two ring beating heads also swing, because the embroidery needle of the corresponding needle position does not work, only idles, and does not embroider the rope on the fabric which is not needed in the embroidery design, and does not affect the embroidery, when another color rope needs to be embroidered, the needle bar frame only needs to change the color to another working needle position.

[0068] Specifically, the output shaft of the swing rope driving motor is connected with a transmission synchronous pulley one 31, the total transmission synchronous pulley 34 is fixed on a total synchronous pulley shaft, the total synchronous pulley shaft is provided with a transmission synchronous pulley two 32, the transmission synchronous pulley one 31 and the transmission synchronous pulley two 32 are connected with a transmission synchronous belt 33. The side of the first color ring head is provided with a first color ring head driving pulley 211, the first color ring head driving pulley and the first color ring head are provided with a first color driving synchronous belt, the first color ring head driving pulley and the total transmission synchronous pulley 34 are connected with a first color transmission synchronous belt. The side of the second color ring head is provided with a second color ring head driving pulley 221, the second color ring head driving pulley and the second color ring head are provided with a second color driving synchronous belt, the second color ring head driving pulley and the total transmission synchronous pulley 34 are connected with a second color transmission synchronous belt; the side of the total transmission synchronous pulley is provided with a third color ring head driving pulley 231, the third color ring head driving pulley and the third color ring head are provided with a third color driving synchronous belt, the third color ring head driving pulley and the total transmission synchronous pulley 34 are connected with a third color transmission synchronous belt.
