[0058] 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.

[0059] 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.

[0060] like Figure 1-22 As shown, a rope embroidery device 100 provided according to the first aspect of the utility model includes a loop wheel mechanism, a rope cutting mechanism 70 and at least two rope clamping mechanisms 30.

[0061] The loop wheel mechanism 20 includes a loop wheel assembly, and a rope accommodating portion is provided on the loop wheel assembly. Each rope clamping mechanism 30 is provided with a rope of one specification, and at least two rope clamping mechanisms 30 correspond to ropes of two specifications.

[0062] Each of the rope clamping mechanisms 30 is arranged along the first direction C1 and reciprocates along the first direction C1 so that each of the rope clamping mechanisms 30 can correspond to the loop wheel mechanism 20. The corresponding rope on the rope clamping mechanism 30 is arranged in the rope accommodating portion of the loop wheel assembly.

[0063] It should be noted that each rope clamping mechanism 30 is provided with a rope of a certain specification, and the specification can be understood as the color of the rope, the material of the rope, or the diameter of the rope, etc., which are not listed one by one in this embodiment.

[0064] The rope embroidery device may be provided with two rope clamping mechanisms 30, three rope clamping mechanisms 30, four rope clamping mechanisms 30, or five rope clamping mechanisms 30, which are not listed one by one in this embodiment.

[0065] Take the example of providing four rope clamping mechanisms 30: Figure 14-15 As shown, the first rope clamping mechanism 30, the second rope clamping mechanism 30, the third rope clamping mechanism 30 and the fourth rope clamping mechanism 30 are arranged along the first direction C1. The first rope clamping mechanism 30 is provided with a rope of the first color; the second rope clamping mechanism 30 is provided with a rope of the second color; the third rope clamping mechanism 30 is provided with a rope of the third color; and the fourth rope clamping mechanism 30 is provided with a rope of the fourth color.

[0066] When the loop wheel assembly corresponds to the first rope clamping mechanism 30, the first rope clamping mechanism 30 places the rope of the first color in the rope accommodating portion of the loop wheel assembly, and then the rope pattern embroidered on the cloth is the first color, and at the same time, the rope cutting mechanism 70 cuts the rope of the first color. The first to fourth rope clamping mechanisms 30 all move along the first direction C1, so that the third rope clamping mechanism 30 corresponds to the loop wheel assembly, and the third rope clamping mechanism 30 places the rope of the third color in the rope accommodating portion of the loop wheel assembly, and then the rope pattern embroidered on the cloth is the third color, and at the same time, the rope cutting mechanism 70 cuts the rope of the third color. In this way, multi-color rope embroidery can be realized, which solves the disadvantage that rope embroidery in the related art can only embroider ropes of one color, enriches the types of embroidery products, and meets the market demand for multi-color rope embroidery.

[0067] In practical applications, 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.

[0068] like Figure 1-Figure 4 As shown, the cord embroidery support assembly 10 includes a first telescopic mechanism 11, a first sliding assembly 12, a second telescopic mechanism 13, and a fourth sliding assembly 14. The first telescopic mechanism 11 is the same as the second telescopic mechanism 13, and the first sliding assembly 12 is the same as the fourth sliding assembly 14.

[0069] The first telescopic mechanism 11 is 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. Figure 3 The second telescopic mechanism 13 and the fourth sliding assembly 14 are connected to the first slide plate 122. Figure 3 As shown, the second telescopic mechanism 13 moves along the direction C22.

[0070] The loop wheel mechanism 20 is connected to the first slide plate 122, that is, the loop wheel mechanism 20 can move along the C21 direction. This arrangement allows the loop wheel mechanism 20 to adjust its position as needed. For example, when rope embroidery is required, the loop wheel mechanism 20 is set away from the embroidery frame of the computer embroidery machine; when rope embroidery is required, the loop wheel mechanism 20 is set close to the embroidery frame of the computer embroidery machine, that is, the loop wheel mechanism 20 is along the C21 direction.

[0071] Specifically: Figure 5 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 .

[0072] The loop wheel assembly 21 includes a wheel body 211 and a switching member 212. 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 slide groove 203, which is formed by the depression of the end surface of the wheel body 211. A first through hole 201 and a second through hole 202 are provided on the side wall of the wheel body 211, and the first through hole 201 and the second through hole 202 are connected to the slide groove 203. The first through hole 201 and the second through hole 202 allow the clamping jaw assembly 31 to pass through. The combination formed by the first through hole 201, the second through hole 202 and the slide groove 203 can be understood as the above-mentioned accommodating rope portion.

[0073] like Figure 7 and Fig. 9 As shown, the wheel body 211 includes an upper circular plate 2112, a body 2111 and a lower circular plate 2113 which are 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. Among them, the diameter of the lower circular plate 2113 is greater than the diameter of the body 2111. The bottom 2031 of the chute 203 formed on the lower circular plate 2113. The above-mentioned first through hole 201 and the second through hole 202 are formed on the body 2111. Meshing teeth are formed on the upper circular plate 2112. 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.

[0074] like Figure 7 and Figure 8 As shown, the switching member 212 includes an annular ring 2123, a first arc plate 2121 and a second arc plate 2122, the first and second arc plates are arranged in the vertical direction, and the first arc plate 2121 and the second arc plate 2122 are 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.

[0075] The first arc plate 2121 and the second arc plate 2122 of the switching member 212 are arranged in the slide groove 203 of the wheel body 211, and the length of the first arc plate 2121 is greater than the length of the second arc plate 2122. 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. Among them, 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. The lower end 21211 of the first arc plate 2121 is configured as the above-mentioned rope locking portion.

[0076] When the switching member 212 is in the first switching position, the lower end 21211 of the first arc plate 2121 is spaced from the bottom 2031 of the slide slot 203, and at this moment, the clamping jaw assembly 31 can pass through the first through hole 201 and the second through hole 202. When the switching member 212 is switched from the first switching position to the second switching position, the lower end 21211 of the first arc plate 2121 abuts against the bottom 2031 of the slide slot 203, and at this moment, the clamping jaw assembly 31 can pass through the second through hole 202.

[0077] It should be noted that the first arc plate 2121 and the second arc plate 2122 cooperate with the slide groove 203 to prevent rotation.

[0078] The wheel body support frame 22 and the switching drive member 23 are connected to the first slide plate 122. The wheel body support member 25 is connected to the wheel body support frame 22, and the wheel body 211 is sleeved on the wheel body 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 to rotate. Since the slide groove 203 of the wheel body 211 and the first arc plate 2121 and the second arc plate 2122 of the switching member 212 are anti-rotationally matched, the wheel body 211 and the switching member 212 form a whole that rotates together. That is, the loop wheel assembly 21 rotates to perform rope embroidery.

[0079] Furthermore, if Figure 6 As shown, the looping wheel mechanism 20 further includes a blowing assembly 28, which 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 angle between the airflow direction of the air nozzle and the direction from the second through hole 202 to the first through hole 201 is α, α = 90°.

[0080] In some embodiments of the present invention, the cord embroidery device 100 further includes a linear reciprocating motion mechanism 50, and the linear reciprocating motion mechanism 50 enables each cord clamping mechanism 30 to move along the first direction C1.

[0081] In detail, Figure 10-13 As shown, the linear reciprocating motion mechanism 50 includes a first support frame 51, a second support frame 52, a transmission assembly 55, a connecting member 56, and a sliding track 53 and a slider 54. The first support frame 51 is connected to the fourth sliding assembly 14, and the first support frame 51 can move along the C22 direction.

[0082] The transmission assembly 55, the first support frame 51, and the second support frame 52 are sequentially arranged from top to bottom, the length of the transmission assembly 55 is arranged along the first direction C1, and the transmission assembly 55 is installed on the surface of the first support frame 51 facing away from the second support frame 52. The track 53 and the slider 54 are located between the first support frame 51 and the second support frame 52, the length direction of the track 53 is arranged along the first direction C1, one of the track 53 and the slider 54 is connected to the surface of the first support frame 51 facing the second support frame 52, and the other is connected to the surface of the second support frame 52 facing the first support frame 51.

[0083] Each rope clamping mechanism 30 is connected to the surface of the second support frame 52 facing away from the first support frame 51 . The transmission assembly 55 is a belt transmission assembly or a chain transmission assembly. The belt or chain of the transmission assembly 55 is connected to the second support frame 52 via a connector 56 .

[0084] When the linear reciprocating mechanism 50 is working, the belt or chain of the transmission assembly 55 drives the second support frame 52 to reciprocate along the first direction C1, and the track 53 and the slider 54 between the first support frame 51 and the second support frame 52 enable the second support frame 52 to move freely, thereby preventing the second support frame 52 from getting stuck. Each rope clamping mechanism 30 is connected to the surface of the second support frame 52 facing away from the first support frame 51, and then each rope clamping mechanism 30 reciprocates along the first direction C1.

[0085] In this configuration, the transmission component 55 is understood to play a driving role, and the slidingly matched track 53 and slider 54 can be understood to play a guiding role, thereby ensuring that each rope clamping mechanism 30 can stably reciprocate along the first direction C1. In addition to the above-mentioned structure, the transmission component 55 can also be other structures, which are not listed one by one in this embodiment.

[0086] In some embodiments of the present invention, the rope clamping mechanism 30 includes a clamping jaw assembly 31, which includes a first clamping jaw 311 and a second clamping jaw 312 that move relative to each other and a clamping jaw mounting plate 313 connecting the first clamping jaw 311 and the second clamping jaw 312, and the clamping jaw mounting plate 313 performs linear reciprocating sliding.

[0087] It should be noted that, in one embodiment, the first clamping jaw 311 and the second clamping jaw 312 can move toward or away from each other at the same time. In one embodiment, one of the first clamping jaw 311 and the second clamping jaw 312 is fixed, and the other moves toward or away from the other.

[0088] Specifically, Figure 14-16 As shown, the rope clamping mechanism 30 includes a clamping claw assembly 31 and a third support frame 32. The third support frame 32 is provided with a guide groove 321, and the clamping claw mounting plate 313 is arranged in the guide groove 321, and the clamping claw mounting plate 313 reciprocates along the length direction of the guide groove 321.

[0089] The first clamping jaw 311 is hinged with the clamping jaw mounting plate 313, and the second clamping jaw 312 is fixedly connected with the clamping jaw mounting plate 313. The first clamping jaw 311 and the second clamping jaw 312 are connected by a tension spring. The clamping jaw mounting plate 313 is provided with an avoidance notch 3131, and the first stopper 33 is connected in the guide groove 321 and is located in the extension direction of the guide groove 321, so that the moving clamping jaw mounting plate 313 can avoid and cooperate with the first stopper 33 through the avoidance notch 3131. The first clamping jaw 311 is provided with a first abutting portion 3111, and the first abutting portion 3111 is matched with the first stopper 33 to make the first clamping jaw 311 be able to be set away from the second clamping jaw 312. At this moment, the clamping jaw assembly 31 releases the rope; the first abutting portion 3111 is matched with the first stopper 33 without stopping, and the first clamping jaw 311 and the second clamping jaw 312 are in contact. At this moment, the clamping jaw assembly 31 clamps the rope.

[0090] Furthermore, if Fig.15 As shown, the rope clamping mechanism 30 further includes a connecting rod assembly 34, and the connecting rod assembly 34 is connected to the clamping jaw mounting plate 313 so that the clamping jaw mounting plate 313 performs linear reciprocating motion.

[0091] It should be noted that the driving mechanism 60 is installed on the first support frame 51. The driving mechanism 60 can make linear motion to drive the connecting rod assembly 34 to move, and then the connecting rod assembly 34 drives the clamping jaw mounting plate 313 to make linear reciprocating motion. The connecting rod assembly 34 is equivalent to a motion mode switch to convert the vertical linear motion output by the driving mechanism 60 into a horizontal linear motion. This embodiment does not limit the structure of the connecting rod assembly 34 and the driving mechanism 60.

[0092] For example, the connecting rod assembly 34 includes a bending rod, and the bending rod includes a first rod body 341 and a second rod body 342. The second rod body 342 is connected to the clamping jaw mounting plate 313. A U-shaped notch 3411 is provided at the end of the first rod body 341.

[0093] like Fig.13 As shown, the driving mechanism 60 includes a rack 62, a gear 61, and a pulley 63 connected to the rack 62. The rack 62 and the gear 61 are meshed and matched, so that the pulley 63 reciprocates in the vertical direction.

[0094] Each of the rope clamping mechanisms 30 reciprocates along the first direction C1, and the pulley 63 of the driving mechanism 60 can pass through the U-shaped notch 3411 on the first rod body 341 of the connecting rod assembly 34 of each of the rope clamping mechanisms 30. When the pulley 63 of the driving mechanism 60 corresponds to the U-shaped notch 3411 on the first rod body 341 of the connecting rod assembly 34 of a rope clamping mechanism 30, the driving mechanism 60 drives the clamping claw mounting plate 313 of the corresponding clamping claw assembly 31 of the rope clamping mechanism 30 to slide back and forth in a straight line. The pulley 63 can be adapted to the U-shaped notch 3411, and the two are rotated to match, so as to reduce the friction between the two and avoid wear on the pulley 63 and the U-shaped notch 3411.

[0095] In addition, if Fig.15 As shown, the guide groove 321 still has a first limiting member 322. When the first abutting portion 3111 of the first clamping jaw 311 cooperates with the first stop member 33,

[0096] The first limiting member 322 limits the position of the clamping jaw mounting plate 313 at the current moment to limit the opening degree of the first clamping jaw 311 relative to the second clamping jaw 312 to prevent the first clamping jaw 311 from opening too much relative to the second clamping jaw 312 .

[0097] like Fig.16 As shown, a first rope guide 36, a second rope guide 35 and a third rope guide 37 are provided on one surface of the third support frame 32, and the surface is arranged opposite to the surface provided with the guide groove 321. The first rope guide 36 is hingedly connected to the third support frame 32, and the first rope guide 36 corresponds to two limiters to limit the swing angle of the first rope guide 36. The rope passes through the second rope guide 35, the first rope guide 36 and the third rope guide 37 in sequence and enters between the first clamping jaw 311 and the second clamping jaw 312.

[0098] In some embodiments of the present invention, the cord embroidery device 100 further includes a cord feeding mechanism 40. The cord feeding mechanism 40 includes an active cord feeding member 41 and at least two driven cord feeding members 42. The driven cord feeding members 42 correspond to the cord clamping mechanism 30 one by one, and each driven cord feeding member 42 can reciprocate along the first direction C1, so that each driven cord feeding member 42 can cooperate with the active cord feeding member 41, and the cord corresponding to the driven cord feeding member 42 is delivered to a preset length.

[0099] In practical applications, each rope clamping mechanism is provided with a rope of a certain specification. For example, the first rope clamping mechanism, the second rope clamping mechanism, the third rope clamping mechanism and the fourth rope clamping mechanism are arranged along the first direction C1. The first rope clamping mechanism is provided with a rope of a first color; the second rope clamping mechanism is provided with a rope of a second color; the third rope clamping mechanism is provided with a rope of a third color; and the fourth rope clamping mechanism is provided with a rope of a fourth color.

[0100] The first, second, third, and fourth color ropes require independent power to output them. Or, when the second color rope is working, the first color rope and the third color rope are in a relaxed state, and the second color rope is tangled with the first and third color ropes.

[0101] Based on this, Fig.11 As shown, the active rope feeding member 41 is connected to the first support frame 51, each driven rope feeding member 42 is connected to the rope frame 43, and the rope frame 43 is connected to the second support frame 52. Therefore, each driven rope feeding member can reciprocate along the first direction C1.

[0102] Among them, Figure 18-Figure 20 As shown, the active rope feeding member 41 is connected to the first support frame 51 through a track and a slider, and the active rope feeding member 41 can be close to or away from the driven rope feeding member 42 to have a matching switching position and a disengaging switching position. The active rope feeding member 41 is in the disengaging switching position, and the active rope feeding member 41 and the driven rope feeding member 42 are arranged to allow the driven rope feeding member 42 to reciprocate along the first direction C1. Such an arrangement prevents the active rope feeding member 41 from interfering with the reciprocating movement of each rope clamping mechanism 30 along the first direction C1.

[0103] The active rope feeding member 41 is in the matching switching position, the active rope feeding member 41 is an active damping wheel, and the driven rope feeding member 42 is a driven damping wheel, and the driven damping wheel and the active damping wheel are frictionally matched. The active rope feeding member 41 is in contact with the driven rope feeding member 42, and the rope corresponding to the driven rope feeding member 42 is conveyed to a preset length. In this way, the friction between the active rope feeding member 41 and the driven rope feeding member 42 is used as the power for rope conveying, so that the rope is continuously conveyed to the first clamping jaw 311 and the second clamping jaw 312.

[0104] The rope rack 43 is provided with a first rope hole 431, a second rope hole 432, a third rope hole 433, and a fourth rope hole 434 from top to bottom. A driven rope feeding member 42 is provided between the first rope hole 432 and the third rope hole 433. The rope passing through the fourth rope hole 434 enters the second rope guide member 35 of the rope clamping mechanism 30.

[0105] In some embodiments of the present invention, the rope cutting mechanism 70 includes a scissor assembly 71 and a first telescopic mechanism 73. The first telescopic mechanism 73 enables the scissor assembly 71 to move closer to or farther away from the table of the computer embroidery machine.

[0106] It should be noted that if Fig.21As shown, the scissor assembly 71 is arranged in the horizontal direction, and the scissor assembly 71 is moved close to or away from the table of the computer embroidery machine through the first telescopic mechanism 73. After the scissor assembly 71 cuts the rope, the length of the rope end remaining on the fabric can be set according to the needs. When the length of the rope end remaining on the fabric is short, the scissor assembly 71 is close to the table of the computer embroidery machine; when the length of the rope end remaining on the fabric is long, the scissor assembly 71 is away from the table of the computer embroidery machine.

[0107] Furthermore, the rope clamping mechanism 30 includes a clamping claw assembly 31, and the scissors assembly 71, the loop wheel assembly 21, and the clamping claw assembly 31 are arranged in sequence.

[0108] like Fig. 22 As shown, the first rope clamping mechanism 30a is provided with a first clamping jaw assembly 31a, the second rope clamping mechanism 30b is provided with a second clamping jaw assembly 31b, the third rope clamping mechanism 30c is provided with a third clamping jaw assembly 31c, and the fourth rope clamping mechanism 30d is provided with a fourth clamping jaw assembly 31d. The first clamping jaw assembly 31a to the fourth clamping jaw assembly 31d are arranged along the first direction C1.

[0109] The first to fourth jaw assemblies 31a to 31d can reciprocate along the first direction C1, so that each jaw assembly 31 can correspond to the loop wheel assembly 21. The jaw assembly 31, the loop wheel assembly 21, and the scissor assembly 71 are sequentially arranged along the C3 direction, and the C3 direction is perpendicular to the C1 direction.

[0110] In this way, each clamping jaw assembly 31 can correspond to the scissors assembly 71 , and then the scissors assembly 71 can cut the rope on each clamping jaw assembly 31 .
