[0049] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0050] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0051] like Figure 1-17 As shown, a loop wheel mechanism 20 of a cord embroidery device 100 provided according to the first aspect of the utility model includes a loop wheel assembly 21, and the loop wheel assembly 21 is provided with a cord accommodating portion and a cord locking portion.

[0052] The rope locking portion moves relative to the rope accommodating portion and has a first switching position and a second switching position. When the rope locking portion is in the first switching position, the rope can enter the rope accommodating portion; when the rope locking portion is in the second switching position, the rope locking portion locks the rope in the rope accommodating portion.

[0053] It should be noted that the loop wheel assembly 21 can be an integral body, and the loop wheel assembly 21 is provided with a rope accommodating portion and a rope locking portion. The loop wheel assembly 21 can be divided into two independent parts, one of which is provided with a rope accommodating portion, and the other of which is provided with a rope locking portion. The loop wheel assembly 21 can be divided into three independent parts, one of which is provided with a rope accommodating portion, and the other of which is provided with a rope locking portion. This embodiment is not listed one by one.

[0054] In practical applications, the cord embroidery device 100 further includes a cord clamping mechanism 30 , and the cord clamping mechanism 30 includes a clamping claw assembly 31 .

[0055] When the rope locking part is in the first switching position, the clamping jaw assembly 31 moves relative to the loop wheel mechanism 20. The clamping jaw assembly 31 clamps the rope to the rope accommodating part and releases the rope to the rope accommodating part. When the rope locking part is in the second switching position, the rope locking part locks the rope in the rope accommodating part. In this way, the loop wheel assembly 21 can automatically thread the rope, avoid manual threading, reduce the labor intensity of the operator, and improve the efficiency of embroidery rope.

[0056] Therefore, in this embodiment, a rope accommodating portion and a rope locking portion are provided on the loop wheel mechanism 20. The rope locking portion moves relative to the rope accommodating portion to have a first switching position and a second switching position, which helps the loop wheel assembly to cooperate with the clamping claw assembly 31 of the rope clamping mechanism 30, thereby realizing automatic rope threading of the loop wheel assembly 21.

[0057] Preferably, the loop wheel assembly 21 can be divided into two independent parts. The following embodiment is described by taking the loop wheel assembly 21 including a wheel body 211 and a switching member 212 as an example:

[0058] In some embodiments of the present invention, a rope accommodating portion is provided on the wheel body 211, and a rope locking portion is provided on the switching member 212. The switching member 212 reciprocates along the axis direction of the wheel body 211 and has a first switching position and a second switching position.

[0059] In the first embodiment, if Figure 9-11 As shown, the wheel body 211 can be cylindrical, and the axis of the wheel body 211 is arranged along the vertical direction. The wheel body 211 has a slide groove 203, which is formed by the depression of the end surface of the wheel body 211. A first through hole 201 is provided on the side wall of the wheel body 211, and the first through hole 201 is connected to the slide groove 203. The first through hole 201 allows the clamping jaw assembly 31 to pass through. The combination formed by the first through hole 201 and the slide groove 203 can be understood as the above-mentioned accommodating rope portion.

[0060] The switching member 212 includes a first arc plate 2121, which is matched with the inner surface of the slide groove 203, so that the first arc plate 2121 is disposed in the slide groove 203 and reciprocates in the vertical direction in the slide groove 203. The lower end 21211 of the first arc plate 2121 is configured as the above-mentioned rope locking part. The first arc plate 2121 and the first through hole 201 correspond to the same arc segment in the circumferential direction of the wheel body 211.

[0061] When the first arc plate 2121 of the switching member 212 is in the first switching position, Fig.12 , 14As shown, the lower end 21211 of the first curved plate 2121 is spaced from the bottom 2031 of the slide slot 203, and at this moment, the lower clamping jaw assembly 31 can pass through the first through hole 201 to place the rope on the bottom 2031 of the slide slot 203. When the first curved plate 2121 of the switching member 212 switches from the first switching position to the second switching position, as shown in FIG. Fig.13 , 15 As shown, the lower end 21211 of the first curved plate 2121 abuts against the bottom 2031 of the slide slot 203 to lock the rope between the first curved plate 2121 of the switching member 212 and the bottom 2031 of the slide slot 203 of the wheel body 211 .

[0062] In the second embodiment, the wheel body 211 is substantially cylindrical, and the axis of the wheel body 211 is arranged in the vertical direction. The bottom surface of the wheel body 211 extends radially outward to form a first boss, and a first blind hole is provided on the side wall of the wheel body 211 near the first boss, and the first blind hole allows the clamping jaw assembly 31 to pass through. The combination of the first blind hole and the first boss can be understood as the above-mentioned rope accommodating portion.

[0063] The switching member 212 may be an annular member, and the switching member 212 is sleeved on the side wall of the wheel body 211, and the switching member 212 reciprocates along the axis of the wheel body 211. The lower end of the switching member 212 is configured as the above-mentioned rope locking part.

[0064] When the switching member 212 is in the first switching position, the lower end of the switching member 212 is spaced from the first boss of the wheel body 211, and the lower end of the switching member 212 does not block the first blind hole, so that the clamping jaw assembly 31 passes through the first blind hole and places the rope in the first blind hole. When the lower end of the switching member 212 switches from the first switching position to the second switching position, the lower end of the switching member 212 abuts against the first boss of the wheel body 211 to lock the rope between the lower end of the switching member 212 and the first boss of the wheel body 211.

[0065] Of course, it is understandable that the wheel body 211 and the switching member 212 may be other suitable structures besides the structures in the first and second embodiments described above, which are not listed one by one in this embodiment.

[0066] In some embodiments of the present invention, a rope accommodating portion is provided on the wheel body 211, and a rope locking portion is provided on the switching member 212. The switching member 212 reciprocates around the axis of the wheel body 211 and has a first switching position and a second switching position.

[0067] In the third embodiment, the wheel body 211 may be cylindrical, and the axis of the wheel body 211 is arranged in the vertical direction. The wheel body 211 has a groove, which is formed by the depression of the end surface of the wheel body 211. A second through hole is provided on the side wall of the wheel body 211, and the second through hole is connected to the groove. The second through hole allows the clamping jaw assembly 31 to pass through. The second through hole is configured with the above-mentioned accommodating rope portion.

[0068] The switching member 212 may be an annular member, and the switching member 212 is adapted to the groove so that the switching member 212 is disposed in the groove, and the switching member 212 can reciprocate around the axis of the wheel body 211. A third through hole is provided on the side wall of the switching member 212 along its radial direction, and the third through hole penetrates the side wall of the switching member 212. The third through hole allows the clamping jaw assembly 31 to pass through. The third through hole is configured as the above-mentioned rope locking portion.

[0069] When the switching member 212 is in the first switching position, the third through hole of the switching member 212 corresponds to the second through hole of the wheel body 211, so that the clamping claw assembly 31 can pass through the second through hole to the third through hole, and the clamping claw assembly 31 releases the rope to the third through hole and the second through hole. When the switching member 212 switches from the first switching position to the second switching position, the rope is locked between the switching member 212 and the wheel body 211 through the damping cooperation between the switching member 212 and the groove.

[0070] Of course, it is understandable that the wheel body 211 and the switching member 212 may be other suitable structures besides the structures in the third embodiment described above, which are not listed one by one in this embodiment.

[0071] Taking into account the process difficulty and processing cost of the wheel body 211 and the switching member 212, and the stability of the rope locked between the switching member 212 and the wheel body 211, the wheel body 211 and the switching member 212 in the first embodiment are preferred.

[0072] The following embodiments are described by taking the wheel body 211 and the switching member 212 in the first embodiment as examples:

[0073] In some embodiments of the present invention, the bottom 301 of the slide groove 203 is in a step shape, or the bottom portion of the slide groove 203 that contacts the first arc-shaped plate 2121 is in a step shape.

[0074] like Fig. 9 , Fig.11 As shown, a circular hollow area is provided on the bottom 2031 of the slide slot 203, so that the bottom 2031 of the slide slot 203 is in a two-stage step shape, including a first upper step and a first lower step arranged up and down. Correspondingly, the lower end 21211 of the first arc plate 2121 of the switching member 212 is in a two-stage step shape, including a second upper step and a second lower step arranged up and down.

[0075] The second upper step is in clearance with the first upper step, and the gap between the second upper step and the first upper step is slightly larger than the diameter of the rope, so as to prevent the rope from being stuck between the second upper step and the first upper step, thereby affecting the switching member 212 from being separated from the bottom 2031 of the sliding groove 203. The second lower step is in clearance with the first lower step, and similarly, it will not be described in detail.

[0076] In addition, the bottom 2031 of the slide groove 203 is in a two-step shape, which increases the length of the rope in contact with the bottom 2031 of the slide groove 203, so that a longer rope is pressed between the bottom 2031 of the slide groove 203 and the lower end 21211 of the first arc plate 2121, thereby helping to improve the stability of the wheel body 211 and the switching member 212 in locking the rope.

[0077] Of course, it can be understood that in some embodiments, a circular hollow area is provided on the bottom 2031 of the slide groove 203, so that the cross section of the bottom 2031 of the slide groove 203 is gradually changed along the axis direction of the wheel body 211. For example, the bottom 2031 of the slide groove 203 is tapered, and the cross section of the bottom 2031 of the slide groove 203 gradually decreases from top to bottom; correspondingly, the lower end 21211 of the first curved plate 2121 of the switching member 212 is roughly conical, and the cross section of the lower end 21211 of the first curved plate 2121 gradually decreases from top to bottom. This embodiment is not listed one by one.

[0078] In practical applications, such as Figure 1 , Figure 2 As shown, the cord embroidery device 100 further includes a cord embroidery support assembly 10, and the cord embroidery support assembly 10 is connected to the head shell 200 of the computer embroidery machine.

[0079] like Figure 3-Figure 5 As shown, the cord embroidery support assembly 10 includes a first telescopic mechanism 11 and a first sliding assembly 12. The first telescopic mechanism 11 can be an electric push rod or a pneumatic push rod. The first sliding assembly 12 includes a first slide rail 121 and a first slide plate 122 that are slidably matched. The first slide rail 121 is arranged in the vertical direction. The first telescopic mechanism 11 drives the first slide plate 122 to slide along the first slide rail 121, and then the first slide plate 122 slides up and down in the vertical direction.

[0080] The loop wheel mechanism 20 is connected to the first slide plate 122. Specifically:

[0081] like Figure 6 As shown, the loop wheel mechanism 20 includes a loop wheel assembly 21, a wheel body support frame 22, a switching drive member 23, a shift fork 24, a wheel body support member 25, a driving pulley 271, and a belt 272. Fig. 9As shown, the loop wheel assembly 21 includes a wheel body 211 and a switching member 212, the switching member 212 includes an annular ring 2123 and a first arc plate 2121, the first arc plate 2121 is arranged in the vertical direction, and the first arc plate 2121 is connected to the annular ring 2123. The annular ring 2123 is provided with an annular groove, and the annular groove is inserted and matched with the shift fork 24.

[0082] like Fig. 9 As shown, the wheel body 211 includes an upper circular plate 2112, a body 2111 and a lower circular plate 2113 arranged in sequence from top to bottom, the upper circular plate 2112 and the body 2111 are integrally formed, and the combination of the upper circular plate 2112 and the body 2111 is detachably connected to the lower circular plate 2113, for example, the two are connected by fasteners. This can reduce the difficulty of processing and reduce production costs. Of course, it is understandable that in some embodiments, the upper circular plate 2112, the body 2111 and the lower circular plate 2113 are integrally formed.

[0083] The diameter of the lower circular plate 2113 is greater than the diameter of the body 2111. The bottom 2031 of the slide groove 203 is formed on the lower circular plate 2113. The first through hole 201 is formed on the body 2111. The upper circular plate 2112 is formed with meshing teeth.

[0084] like Figure 6 As shown, the wheel support frame 22 and the switching drive member 23 are connected to the first slide plate 122. The wheel support member 25 is connected to the wheel support frame 22, and the wheel body 211 is sleeved on the wheel support member 25, and a bearing 26 is provided between the two. The fork 24 is connected to the switching drive member 23, and the fork 24 drives the switching member 212 to reciprocate along the axis of the wheel body 211. The belt 272 is wound around the meshing teeth and the active pulley 271, thereby driving the wheel body 211 and the switching member 212 in the second switching position to rotate as a whole. That is, the loop wheel assembly 21 rotates to perform rope embroidery.

[0085] Furthermore, at least one of the first arc plate 2121 and the second arc plate 2122 is engaged with the slide groove 203 to prevent rotation.

[0086] like Fig. 9As shown, the slide 203 includes a first part and a second part, the first part matches the first arc plate 2121, and the second part matches the second arc plate 2122. When the first arc plate 2121 is in the second switching position, the first arc plate 2121 and the second arc plate 2122 are both anti-rotationally matched with the slide 203. The driving pulley 271 rotates, and the belt 272 cooperates with the meshing teeth on the wheel body 211, and then the wheel body 211 rotates. Since the first arc plate 2121 and the second arc plate 2122 are both anti-rotationally matched with the slide 203, the wheel body 211 and the switching member 212 rotate together, and no relative motion is generated between the two. That is, the loop wheel assembly 21 rotates to perform rope embroidery.

[0087] In some embodiments of the utility model, a second through hole 202 connected to the slide groove 203 is also provided on the side wall of the wheel body 211. The second through hole 202 is arranged opposite to the first through hole 201. The second through hole 202 is used to allow the clamping claw assembly 31 of the rope clamping mechanism 30 of the rope embroidery device 100 to pass through.

[0088] like Fig.10 As shown, the switching member 212 includes an annular ring 2123, a first arc plate 2121 and a second arc plate 2122, and the length of the second arc plate 2122 is less than the length of the first arc plate 2121. The first arc plate 2121 and the second arc plate 2122 are arranged opposite to each other and are both connected to the annular ring 2123.

[0089] The side wall of the wheel body 211 is provided with a second through hole 202 and a first through hole 201 which are connected to the slide groove 203, and the second through hole 202 is arranged opposite to the first through hole 201. The second through hole 202 and the second arc plate 2122 correspond to the same arc segment in the circumferential direction of the wheel body 211, and the first through hole 201 and the first arc plate 2121 correspond to the same arc segment in the circumferential direction of the wheel body 211. With such arrangement, the combination of the two arc plates can suppress the shaking of the switching member 212 in the circumferential direction of the wheel body 211, so that the first arc plate 2121 only moves in the vertical direction.

[0090] In addition, it should be noted that Figure 12-Figure 15 As shown, when the first arc plate 2121 is in the first switching position or in the second switching position, the second arc plate 2122 does not affect the clamping jaw assembly 31 passing through the second through hole 202 .

[0091] like Fig.16a-d shows a process of the clamping jaw assembly 31 cooperating with the wheel body 211 of the loop wheel assembly 21. When the clamping jaw assembly 31 is at the C33 position, the rope is in a U-shape in the wheel body 211. Then, when the switching member 212 is at the second switching position, the switching member 212 may not be able to hold down the rope, or the switching member 212 may not hold down the rope well, and the rope cannot be stably locked between the wheel body 211 and the switching member 212.

[0092] Based on this, a notch 21131 is provided on the lower circular plate 2113, and the notch 21131 and the first through hole 201 correspond to the same arc segment in the circumferential direction of the wheel body 211. When the clamping jaw assembly 31 moves from the position C33 to the position C34, the end of the rope can rebound from the notch 21131, and the rope can be located in the wheel body 211 in a straight line. Fig.17 As shown, the probability that the switching member 212 presses the rope is greatly improved.

[0093] Furthermore, if Figure 7 and Figure 8 As shown, the looping wheel mechanism 20 also includes a blowing assembly 28, and the blowing assembly 28 is connected to the wheel body support frame 22. The air nozzle of the blowing assembly 28 faces the first through hole 201, and the air flow direction of the air nozzle ( Figure 8 The dashed arrow in the middle) and the direction from the second through hole 202 to the first through hole 201 ( Figure 8 The angle between them (solid arrow in the middle) is α=90°.

[0094] For example, Fig.16c As shown in FIG. 1 , when the clamp assembly 31 is at position C33, the rope is in a U-shape in the wheel body 211. The airflow through the air nozzle causes the end of the rope to rebound, and the rope can be in a straight line in the wheel body 211, as shown in FIG. Fig.17 As shown, the switch 212 helps to press the rope.

[0095] Of course, it is understandable that the air nozzle of the blowing assembly 28 faces the second through hole 202 , and the air flow direction of the air nozzle is the same as the direction from the second through hole 202 to the first through hole 201 .
