[0002] Embroidery equipment. Background Art

[0003] Computerized embroidery involves a pattern maker creating a computerized pattern based on the desired design. This pattern is then embroidered on a computerized embroidery machine. After appropriate revisions, the final pattern is entered into the machine for batch production, creating the final embroidery pattern. Currently, computerized embroidery machines offer a wide variety of patterns, including towel embroidery, rope embroidery, ribbon embroidery, and sequin embroidery, to meet the diverse needs of individual customers.

[0004] Gold embroidery is a common embroidery technique with unique expressive features. It is often combined with other embroidery methods and embroidery machines. Existing gold embroidery techniques typically involve the embroidery machine needle dropping through the gold flakes, then using embroidery thread to secure the flakes to the embroidery cloth. The flakes are arranged according to the embroidery pattern to form a gold pattern. In other words, existing gold embroidery techniques fix the gold flakes on the cloth, failing to achieve the effect of floating flakes. Summary of the Invention

[0035] The present invention also proposes a gold sheet floating embroidery device, comprising: a flat embroidery machine head, a towel device arranged on the rear side of the flat embroidery machine head, and a gold sheet embroidery device arranged on one side of the flat embroidery machine head, the flat embroidery machine head is provided with an upper thread and a needle bar assembly, the gold sheet embroidery device is used to transport gold sheets, the needle bar assembly is used to drive the upper thread to move, so that the upper thread sequentially passes through the inner ring of the gold sheet transported by the gold sheet embroidery device and the cloth, and the gold sheet is sleeved on the upper thread, the towel device is used to drive the upper thread to form a thread loop, so that the gold sheet sleeved on the upper thread can move along the axial direction of the thread loop.

[0036] Furthermore, the towel device includes a first connecting frame fixedly connected to the rear side of the flat embroidery machine head, a first driving mechanism provided on the first connecting frame, and a swinging mechanism provided on the first driving mechanism, the first driving mechanism is used to drive the swinging mechanism to move on the rear side of the flat embroidery machine head, and the swinging mechanism is used to loop the surface thread.

[0037] Furthermore, the gold sheet embroidery device includes a second connecting frame fixedly connected to one side of the flat embroidery machine head, a second driving mechanism provided on the second connecting frame, a film feeding mechanism provided on the second driving mechanism, and a slicing mechanism provided on the film feeding mechanism. The second driving mechanism is used to drive the film feeding mechanism to move on one side of the flat embroidery machine head, the film feeding mechanism is used to feed the gold sheet, and the slicing mechanism is used to cut the gold sheet fed by the film feeding mechanism.

[0038] The gold sheet floating embroidery method and floating sheet embroidery equipment proposed by the present invention have the following beneficial effects:

[0039] (1) This embroidery method uses a towel device to drive the upper thread to form a thread loop, and then sets the gold piece on the thread loop formed by the upper thread, so that the gold piece can move along the axis of the thread loop, thereby achieving the effect of floating piece embroidery, enriching the embroidery variety and meeting the different needs of customers;

[0040] (2) This embroidery method first completes a row of float embroidery on the fabric, and then repeats the above steps to complete multiple rows of float embroidery on the fabric, thereby performing embroidery on a large area of ​​the fabric and completing the embroidery of the embroidery product. Using this method for float embroidery can, on the one hand, make the float embroidery more regular and improve the quality of the embroidery product; on the other hand, it can reduce the relative movement distance between the embroidery frame and the flat embroidery machine head, thereby improving the embroidery efficiency and further improving the production efficiency;

[0041] (3) When the embroidery device performs floating piece embroidery, the second driving mechanism is operated to drive the feeding mechanism to move, so that the feeding mechanism moves away from the end of the second driving mechanism to between the needle bar assembly and the fabric, thereby delivering the sequins through the film outlet end of the feeding mechanism. When the needle bar assembly lowers the needle, the needle bar assembly drives the upper thread to pass through the inner ring of the sequins;

[0042] (4) When the embroidery equipment performs floating piece embroidery, the feeding mechanism transports the gold piece belt. When the gold piece at the end of the gold piece belt is transported to the output end, the gold piece at the end of the gold piece belt is cut off from the adjacent gold pieces by the slicing mechanism, so that it becomes an independent gold piece. When the needle bar assembly lowers the needle, the upper thread is driven to pass through the gold piece, and then a gold piece is set on a thread loop of the upper thread.

[0043] (5) The second guide rail of the embroidery equipment is tilted, so when the second driving member drives the second slide to move on the second guide rail, the film feeding mechanism is driven to move synchronously and tilted, so that the film outlet end of the film feeding mechanism moves from one side of the flat embroidery machine head to between the needle bar assembly and the fabric, thereby preventing the frame of the flat embroidery machine head from obstructing the movement of the film feeding mechanism, and allowing the film outlet end of the film feeding mechanism to move smoothly between the needle bar assembly and the fabric, preventing the film outlet end of the film feeding mechanism from colliding with the frame of the flat embroidery machine head, thereby ensuring the service life of the flat embroidery machine head and the gold film embroidery device;

[0044] (6) The first guide rail of the embroidery equipment is tilted, so when the first driving member drives the first slide to move on the first guide rail, it drives the swing mechanism to move synchronously and tilt, so that the film outlet end of the swing mechanism moves tiltedly from the rear side of the flat embroidery machine head to between the needle bar assembly and the fabric, thereby preventing the frame of the flat embroidery machine head from hindering the movement of the swing mechanism, and allowing the swing end of the swing mechanism to move smoothly between the needle bar assembly and the fabric, preventing the swing end of the swing mechanism from colliding with the frame of the flat embroidery machine head, thereby ensuring the service life of the flat embroidery machine head and the gold piece embroidery device;

[0045] (7) The swing mechanism of the embroidery device includes a swing motor, a swing seat, and a swing needle. The swing motor is mounted on the first connecting frame. The swing seat is connected to the rotating shaft of the swing motor. The swing needle is mounted on the swing seat. When performing floating embroidery, the swing motor is operated, causing the rotating shaft of the swing motor to rotate bidirectionally by a certain angle, thereby driving the swing seat to synchronously rotate bidirectionally by a certain angle, and then driving the swing needle to swing by a certain angle. The swing needle acts on the upper thread, causing the upper thread to form a thread loop. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0057] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0058] See also Figures 1 to 9 The present invention discloses a method and apparatus for embroidering gold foil with floating pieces. The apparatus comprises a flat embroidery head 1, an embroidery frame, a towel device 2, and a gold foil embroidery device 3. The flat embroidery head 1 is provided with an upper thread. The embroidery frame is provided below the flat embroidery head 1, the towel device 2 is provided at the rear of the flat embroidery head 1, and the gold foil embroidery device 3 is provided on the left or right side of the flat embroidery head 1. The fabric to be embroidered is placed on the embroidery frame and is kept taut on the frame. By pressing the non-embroidered area of ​​the fabric, the upper and lower sides of the embroidered area of ​​the fabric are suspended, making it easier to embroider the fabric.

[0059] In actual use, the floating piece embroidery method includes the following steps:

[0060] Step S1: Fix the fabric to be embroidered on the embroidery frame;

[0061] Step S2: moving the needle bar assembly 11 of the flat embroidery machine head 1 to the initial needle lowering position of the fabric;

[0062] Step S3: moving the towel device 2 and the sequin embroidery device 3 to designated positions;

[0063] Step S4: the towel device 2 swings, the needle bar assembly 11 lowers the needle, and the upper thread passes through the fabric. After the upper thread is locked, the needle bar assembly 11 returns the needle.

[0064] Step S5: moving the needle bar assembly 11 to the next needle position of the fabric;

[0065] Step S6: The sequin embroidery device 3 feeds the sequins, and the needle bar assembly 11 lowers the needle again, so that the upper thread passes through the inner ring of the sequins and the fabric in sequence. At the same time, the towel device 2 swings, driving the upper thread to form a thread loop. After the upper thread is locked, the needle bar assembly 11 returns the needle;

[0066] Step S7: Repeat steps S5 to S6 until the gold flake embroidery is completed on the fabric.

[0067] In the above process steps, the towel device 2 drives the surface thread to form a thread loop, and the gold piece is placed on the thread loop formed by the surface thread, so that the gold piece can move along the axial direction of the thread loop, thereby achieving the effect of floating piece embroidery, enriching the embroidery variety and meeting the different needs of customers.

[0068] Specifically, in this embodiment, the flat embroidery machine head 1 is provided with a thread clamp 12. The upper thread is loaded and delivered through the thread clamp 12. During this process, the thread clamp 12 can adjust the tension of the upper thread. It is foreseeable that the thread clamp 12 includes a thread clamp 12 panel, a barrel disposed on the thread clamp 12 panel, and a tension adjustment assembly disposed on the thread clamp 12 panel. The barrel is used to load the upper thread. The upper thread delivered from the barrel passes through the tension adjustment assembly before being delivered, thereby adjusting the tension of the upper thread through the tension adjustment assembly.

[0069] The upper thread transmitted through the thread clamp 12 is connected to the needle head of the needle bar assembly 11 of the flat embroidery machine head 1, so that when the needle bar assembly 11 performs stitching and backstitching, the upper thread is driven to move synchronously to complete the embroidery work.

[0070] Specifically, in this embodiment, step S2 includes: the embroidery frame moves, while the flat embroidery machine head 1 remains relatively stationary, and the needle bar assembly 11 moves to the initial needle lowering position on the fabric. Similarly, step S5 includes: the embroidery frame moves, while the flat embroidery machine head 1, the towel device 2, and the sequin embroidery device 3 remain relatively stationary, and the needle bar assembly 11 moves to the next needle lowering position on the fabric.

[0071] In this application, the relative movement between the embroidery frame and the flat embroidery machine head 1 is achieved by moving the embroidery frame to drive the movement of the fabric, while the flat embroidery machine head 1, the towel device 2 and the gold piece embroidery device 3 remain relatively fixed, thereby realizing the movement of the needle bar assembly 11 between the lower needle positions of the fabric. At the same time, the relative positions of the towel device 2 and the gold piece embroidery device 3 and the flat embroidery machine head remain unchanged, which is convenient for subsequent embroidery.

[0072] The reason for adopting this movement mode is that the structure of the flat embroidery machine head 1, towel device 2 and gold piece embroidery device 3 is more complicated than the embroidery frame structure. Therefore, the fabric is moved by the embroidery frame, and the flat embroidery machine head 1, towel device 2 and gold piece embroidery device 3 remain relatively fixed, so that the needle bar assembly 11, towel device 2 and gold piece embroidery device 3 can move between the lower needle positions, thereby making the movement between the lower needle positions more stable and accurate, thereby ensuring the quality of the embroidery.

[0073] Specifically, in this embodiment, step S3 includes:

[0074] Step S3.1: Move the swing end of the towel device 2 to below the needle bar assembly 11 so that the swing end is located between the needle bar assembly 11 and the fabric;

[0075] Step S3.2: Move the sheet outlet end of the sequin embroidery device 3 to below the needle bar assembly 11 so that the sheet outlet end is located between the needle bar assembly 11 and the fabric.

[0076] Since in the present application, the towel device 2 is arranged at the rear side of the flat embroidery machine head 1, and the gold piece embroidery device 3 is arranged at the left or right side of the flat embroidery machine head 1, it is necessary to move the towel device 2 and the gold piece embroidery device 3 to designated positions on the flat embroidery machine head 1 during actual embroidery. Specifically, the swing end of the towel device 2 can be first moved to the bottom of the needle bar assembly 11 so that the swing end is located between the needle bar assembly 11 and the fabric. Thus, during floating piece embroidery, the upper thread is driven to form a thread loop by the swing end of the towel device 2.

[0077] Then move the sheet outlet end of the sequin embroidery device 3 to the bottom of the needle bar assembly 11, so that the sheet outlet end is located between the needle bar assembly 11 and the fabric. When embroidering floating pieces, the sequins are delivered through the sheet outlet end of the sequin embroidery device 3, so that the sequins are located between the needle bar assembly 11 and the fabric, making it easier for the needle bar assembly 11 to drive the upper thread through the inner ring of the sequins.

[0078] When the swing end of the towel device 2 and the sheet outlet end of the sequin embroidery device 3 move to the bottom of the needle bar assembly 11, the swing end of the towel device 2 and the sheet outlet end of the sequin embroidery device 3 are displaced in the height direction. Specifically, the sheet outlet end of the sequin embroidery device 3 can be located above the swing end of the towel device 2, that is, the swing end of the towel device 2 is located above the fabric, the sheet outlet end of the sequin embroidery device 3 is located above the swing end of the towel device 2, and the needle bar assembly 11 is located above the sheet outlet end of the sequin embroidery device 3, thereby preventing the swing end of the towel device 2 and the sheet outlet end of the sequin embroidery device 3 from interfering with each other.

[0079] Specifically, in this embodiment, step S4 includes:

[0080] Step S4.1: The swing end of the towel device 2 swings to one side of the needle bar assembly 11 to avoid the needle insertion path of the needle bar assembly 11;

[0081] Step S4.2: The sequin embroidery device 3 delivers the sequins to between the needle bar assembly 11 and the fabric;

[0082] Step S4.3: The needle bar assembly 11 moves the needle downward, driving the upper thread to move synchronously, so that the upper thread passes through the inner ring of the sequin and the fabric in sequence;

[0083] Step S4.4: The bottom of the fabric is locked by the bottom thread and the top thread, and the needle bar assembly 11 is rewound;

[0084] Step S4.5: The swing end of the towel device 2 swings from one side of the needle bar assembly 11 to the other side of the needle bar assembly 11, and abuts against the upper thread.

[0085] Since at the initial needle-dropping position of the fabric, initially, the swinging end of the towel device 2 and the sheet-discharging end of the sequin embroidery device 3 are both located between the needle bar assembly 11 and the fabric, and are dislocated in the height direction, before the needle bar assembly 11 drops the needle, the swinging end of the towel device 2 must be swung to one side of the needle bar assembly 11, so that the swinging end of the towel device 2 avoids the needle-dropping route of the needle bar assembly 11; then the sheet-discharging end of the sequin embroidery device 3 sends the sequins to between the needle bar assembly 11 and the fabric; then the needle bar assembly 11 drops the needle, and the needle bar assembly 11 drives the upper thread to move synchronously, so that the upper thread passes through the inner ring of the sequins and the fabric in turn, and the sequins are placed on the upper thread.

[0086] After the end of the upper thread passes through the fabric, the end of the upper thread is locked by the bottom thread at the bottom of the fabric, thereby fixing the end of the upper thread on the fabric; after the end of the upper thread is fixed, the needle bar assembly 11 is back-stitched; then the swinging end of the towel device 2 is swung from one side of the needle bar assembly 11 to the other side of the needle bar assembly 11, abutting against the upper thread, preparing for the subsequent swinging end of the towel device 2 to swing and drive the upper thread to form a loop.

[0087] Specifically, in this embodiment, step S6 includes:

[0088] Step S6.1: The output end of the sequin embroidery device 3 delivers the next sequin to between the needle bar assembly 11 and the fabric;

[0089] Step S6.2: The needle bar assembly 11 moves the needle downward, driving the upper thread to move synchronously, so that the upper thread passes through the inner ring of the next sequin and the fabric in turn;

[0090] Step S6.3: The swing end of the towel device 2 swings from one side of the needle bar assembly 11 to the other side of the needle bar assembly 11, driving the upper thread to form a thread loop, so that the two gold pieces are placed on the thread loop;

[0091] Step S6.4: The bottom of the fabric is locked by the bottom thread and the top thread, and the needle bar assembly 11 is re-threaded.

[0092] After the needle bar assembly 11 moves to the next needle insertion position on the fabric, the next sequin is first fed between the needle bar assembly 11 and the fabric via the exit end of the sequin embroidery device 3. Then, the needle bar assembly 11 inserts the needle, driving the upper thread to move synchronously, allowing it to pass through the inner loop of the next sequin and the fabric in sequence. When the end of the upper thread passes through the fabric, the swing end of the towel device 2 swings from one side of the needle bar assembly 11 to the other side, driving the portion of the upper thread above the fabric to form a first loop, thereby enclosing both sequins on the first loop.

[0093] After the upper thread forms the first loop at the portion above the fabric, the lower thread is used to lock the end of the upper thread at the bottom of the fabric, thereby fixing the end of the upper thread to the fabric, and then the needle bar assembly 11 is backstitched. Steps S5 to S6 are repeated, and the sequins through which the upper thread passes are named first sequins, second sequins, third sequins, etc., and the end of the upper thread fixed to the fabric is named first end, second end, third end, etc. The loops formed by the upper thread above the fabric driven by the swinging end of the towel device 2 are named first loop, second loop, third loop, etc., and so on, until the floating embroidery of sequins on the fabric is completed.

[0094] In the present application, the first and second ends of the surface thread are located above the fabric to form a first loop, the second and third ends are located above the fabric to form a second loop, and the third and fourth ends are located above the fabric to form a third loop. The first gold piece is placed on the first loop near the first end, and the first gold piece can move around the axis of the first loop; the second gold piece is placed on the first loop near the second end and the second loop near the first end at the same time, and the second gold piece can move around the axis of the first and second loops within a certain range; the third gold piece is placed on the second loop near the second end and the third loop near the first end at the same time, and the third gold piece can move around the axis of the second and third loops within a certain range, and so on. This allows the gold pieces embroidered on the fabric to achieve the effect of floating embroidery, enriching the embroidery variety and meeting the different needs of customers.

[0095] When embroidering, it is usually necessary to embroider a large area on the fabric. Therefore, in this embodiment, when performing floating piece embroidery, step S7 includes:

[0096] Step S7.1: Repeat steps S5 to S6 to complete the floating embroidery of a row of gold flakes on the fabric;

[0097] Step S7.2: Repeat step S7.1 to complete the floating piece embroidery of multiple columns of gold pieces on the fabric.

[0098] By repeating steps S5 to S6, one row of float embroidery is first completed on the fabric, and then the above steps are repeated to complete multiple rows of float embroidery on the fabric, thereby embroidering a large area of ​​the fabric and completing the embroidery work. Using this method for float embroidery can, on the one hand, make the float embroidery more regular and improve the quality of the embroidery work; on the other hand, it can reduce the relative movement distance between the embroidery frame and the flat embroidery machine head 1, thereby improving embroidery efficiency and thus improving production efficiency.

[0099] In this embodiment, the towel device 2 includes a first connecting frame 21, a first driving mechanism and a swinging mechanism. The first connecting frame 21 is fixedly connected to the rear side of the flat embroidery machine head 1. The first driving mechanism is arranged on the first connecting frame 21. The swinging mechanism is arranged on the first driving mechanism. The swinging end is the end of the swinging mechanism away from the first driving mechanism.

[0100] When performing floating embroidery, the first driving mechanism is operated to drive the swinging mechanism to move, so that the swinging mechanism moves away from one end of the first driving mechanism to between the fabric and the needle bar assembly 11, so that when the needle bar assembly 11 drives the upper thread to cross the swinging end of the swinging mechanism, the upper thread forms a loop through the swinging end.

[0101] Specifically, in this embodiment, the first driving mechanism includes a first guide rail 211, a first slide 22, and a first driving member 23. The first guide rail 211 is disposed on the first connecting frame 21, the first slide 22 is slidably connected to the first guide rail 211, and the first driving member 23 is also disposed on the first connecting frame 21. The first driving member 23 is connected to the first slide 22, so that the first driving member 23 drives the first slide 22 to move back and forth on the first guide rail 211.

[0102] Since the swing mechanism is disposed on the first slide 22, when the first slide 22 moves back and forth on the first guide rail 211, it drives the swing mechanism to move back and forth synchronously. Since the first guide rail 211 is tilted, when the first driving member 23 drives the first slide 22 to move on the first guide rail 211, it drives the swing mechanism to move synchronously at an angle, so that the film outlet end of the swing mechanism moves obliquely from the rear side of the flat embroidery machine head 1 to between the needle bar assembly 11 and the fabric, thereby preventing the frame of the flat embroidery machine head 1 from obstructing the movement of the swing mechanism, allowing the swing end of the swing mechanism to move smoothly between the needle bar assembly 11 and the fabric, preventing the swing end of the swing mechanism from colliding with the frame of the flat embroidery machine head 1, and thus ensuring the service life of the flat embroidery machine head 1 and the sequin embroidery device 3.

[0103] In this embodiment, the swing mechanism includes a swing motor 24, a swing base 25, and a swing needle 26. The swing motor 24 is mounted on the first slide 22, the swing base 25 is connected to the rotating shaft of the swing motor 24, and the swing needle 26 is mounted on the swing base 25. During floating embroidery, the swing motor 24 operates, causing the rotating shaft of the swing motor 24 to rotate bidirectionally by a certain angle, thereby driving the swing base 25 to synchronously rotate bidirectionally by a certain angle, which in turn drives the swing needle 26 to swing by a certain angle. The swing needle 26 acts on the upper thread, causing it to form a loop.

[0104] Specifically, in this embodiment, the gold sheet embroidery device 3 includes a second connecting frame 31, a second driving mechanism and a film feeding mechanism 34. The second connecting frame 31 is fixedly connected to one side of the flat embroidery machine head 1. The second driving mechanism is arranged on the second connecting frame 31. The film feeding mechanism 34 is arranged on the second driving mechanism. The film output end is the end of the film feeding mechanism 34 away from the second driving mechanism.

[0105] Therefore, when performing floating piece embroidery, the second driving mechanism is operated to drive the film feeding mechanism 34 to move, so that the film feeding mechanism 34 moves away from the end of the second driving mechanism to between the needle bar assembly 11 and the fabric, thereby delivering the gold piece through the film outlet end of the film feeding mechanism 34. When the needle bar assembly 11 lowers the needle, the needle bar assembly 11 drives the upper thread to pass through the inner ring of the gold piece.

[0106] Specifically, in actual implementation, the film feeding mechanism 34 includes a base plate 341, a first motor 342, a second motor 343, a first fork assembly 344, a second fork assembly 345 and a feeding base plate assembly 346. The first motor 342 and the second motor 343 are respectively fixedly mounted on the base plate 341, and the feeding base plate assembly 346 is arranged at the bottom of the base plate 341.

[0107] The first motor 342 is connected to the first fork assembly 344, and the second motor 343 is connected to the second fork assembly 345. The first motor 342 drives the first fork assembly 344 to operate, so that the first fork assembly 344 shifts the first group of gold sheet tapes on the feeding base plate assembly 346 and conveys the first group of gold sheet tapes toward the sheet outlet end; the second motor 343 drives the second fork assembly 345 to operate, so that the second fork assembly 345 shifts the second group of gold sheet tapes on the feeding base plate assembly 346 and conveys the second group of gold sheet tapes toward the sheet outlet end, thereby realizing double gold sheet feeding of the gold sheet embroidery device 3.

[0108] Furthermore, in the present application, a first swing arm 3421 is provided at the output end of the first motor 342 , and the first fork assembly 344 includes a first fork 3441 and a first pin 3442 , and the first pin 3442 rotatably connects one end of the first fork 3441 to the first swing arm 3421 .

[0109] The feed base assembly 346 includes a base plate 3461 and a first guide plate 3462. The base plate 3461 is mounted on the base plate 341, and the first guide plate 3462 is mounted on the base plate 3461. A first guide trough is provided on the first guide plate 3462, into which the other end of the first fork 3441 is inserted. The first set of gold foil strips passes through the bottom of the first guide trough, and the other end of the first fork 3441 is inserted into the inner hole of the gold foil located in the first guide trough.

[0110] When feeding is required, the first motor 342 drives the first swing arm 3421 to rotate clockwise, and the first swing arm 3421 drives the first fork 3441 to move forward. At the same time, the first fork 3441 rotates counterclockwise around the first pin shaft 3442 to ensure that the first fork 3441 is plugged into the inner hole of the gold sheet, thereby causing the first fork 3441 to push the first group of gold sheet belts forward by one gold sheet position, completing a picking operation.

[0111] In this application, "clockwise" and "counterclockwise" are both based on the front view ( Figure 2 ) The rotation direction of the viewing angle is used as the reference direction, and the "clockwise" and "counterclockwise" appearing below are based on this direction.

[0112] In practice, the first shift fork assembly 344 also includes a first return torsion spring, which is sleeved around the first pin 3442. One end of the first return torsion spring is fixed to the first swing arm 3421, and the other end is fixed to the first shift fork 3441. When the first shift fork assembly 344 performs a shifting operation, the first return torsion spring is compressed. After a shifting operation is completed, the first motor 342 rotates counterclockwise back to its original position. Under the elastic force of the first return torsion spring, which restores its deformation, the first shift fork 3441 retracts to its original position, awaiting the next shifting operation.

[0113] Furthermore, in the present application, a second swing arm 3431 is provided at the output end of the second motor 343, and the second swing arm 3431 is disposed on the back side of the base plate 341. The second fork assembly 345 includes a first swing rod 3451, a second swing rod 3452, a second pin 3453, a second fork 3454, a third pin 3455, and a driving torsion spring. The first swing rod 3451 and the second swing rod 3452 are respectively disposed on either side of the base plate 341, and the second pin 3453 passes through the base plate 341 and is rotationally connected to the base plate 341.

[0114] A driving torsion spring is mounted on the second pin 3453, with one end fixed to the base plate 341 and the other end fixed to the first rocker 3451. In the initial state, one end of the first rocker 3451 abuts the second rocker arm 3431, compressing the driving torsion spring. One end of the second shift fork 3454 is rotationally connected to one end of the second rocker 3452 via the third pin 3455. The second pin 3453 connects the other end of the first rocker 3451 to the other end of the second rocker 3452. The driving torsion spring is mounted on the second pin 3453, with one end fixed to the base plate 341 and the other end fixed to the first rocker 3451.

[0115] The feed base assembly 346 also includes a second guide plate 3463, which is mounted on the inclined surface of the first guide plate 3462, so that the second guide plate 3463 and the first guide plate 3462 are arranged in a stepped height. A second guide trough is provided on the second guide plate 3463, into which the other end of the second fork 3454 is inserted. The second set of gold foil strips emerges from the bottom of the second guide trough, and the other end of the second fork 3454 is inserted into the inner hole of the gold foil located in the second guide trough.

[0116] When feeding is required, the second motor 343 drives the second swing arm 3431 to rotate counterclockwise, so that the second swing arm 3431 no longer abuts against the first swing rod 3451. At this time, under the elastic force of the driving torsion spring, the first swing rod 3451 is driven to rotate clockwise around the second pin shaft 3453, driving the second swing rod 3452 to rotate clockwise around the second pin shaft 3453 synchronously. As a result, under the drive of the second swing rod 3452, the second shift fork 3454 moves forward and rotates counterclockwise around the third pin shaft 3455, ensuring the plug-in state of the second shift fork and the inner hole of the gold sheet, thereby causing the second shift fork 3454 to push the second group of gold sheet belts forward by one gold sheet position, completing a shifting operation.

[0117] In actual implementation, the second shift fork assembly 345 further includes a second return torsion spring, which is sleeved on the third pin 3455. One end of the third return torsion spring is fixed to the second rocker 3452, and the other end is fixed to the second shift fork 3454. When the second shift fork assembly 345 performs a shifting operation, the second return torsion spring is compressed.

[0118] After completing a plucking operation, the second motor 343 rotates back to its original position clockwise, driving the second swing arm 3431 to rotate clockwise, and the second swing arm 3431 abuts against one end of the first swing rod 3451, thereby driving the first swing rod 3451 to rotate counterclockwise around the second pin shaft 3453, and the driving torsion spring is compressed, so that the first swing rod 3451 returns to its initial state; at the same time, under the elastic force of the second reset torsion spring to restore its own deformation, the second shift fork 3454 retreats back to its original position and waits for the next plucking operation.

[0119] Furthermore, in this embodiment, the sequin embroidery device 3 further includes a slicing mechanism 35, which is provided on the sheet feeding mechanism 34 and is located at the sheet outlet end of the sheet feeding mechanism 34. When performing floating sheet embroidery, the sheet feeding mechanism 34 feeds the sequin belt. When the sequin at the end of the sequin belt is conveyed to the sheet outlet end, the sequin at the end of the sequin belt is cut off from the adjacent sequins by the slicing mechanism 35, so that the sequin becomes an independent sequin. When the needle bar assembly 11 lowers the needle, the upper thread is driven to pass through the sequin, and then a sequin is sheathed on a thread loop of the upper thread.

[0120] In actual implementation, the output end of the second motor 343 is further provided with a third swing arm 3432, which is disposed on the front surface of the base plate 341. The slicing mechanism 35 includes a fourth pin 351, a driving arm 352, a connecting rod 353, a torsion arm 354, a fifth pin 355, and a cutter 356. The fourth pin 351 is fixedly mounted on the base plate 341, and the driving arm 352 is rotatably mounted on the fourth pin 351. A first ball head 3531 and a second ball head 3532 are mounted at each end of the connecting rod 353, respectively. One end of the driving arm 352 abuts against the third swing arm 3432, while the other end is movably connected to the first ball head 3531 via a pin.

[0121] The second ball head 3532 is movably connected to one end of the torsion arm 354. The torsion arm 354 is fixedly connected to the fifth pin 355. The fifth pin 355 is rotatably connected to the base plate 341. A torsion spring mounting block is provided on the fifth pin 355. The slicing mechanism 35 also includes a fourth return torsion spring mounted on the fifth pin 355. One end of the fourth return torsion spring is fixed to the torsion spring mounting block and the other end is fixed to the base plate 341. The cutter 356 is mounted on the end of the fifth pin 355.

[0122] When the gold sheet needs to be cut, the second motor 343 drives the third swing arm 3432 to rotate counterclockwise. This third swing arm 3432 lifts one end of the driving arm 352, causing it to rotate about the fourth pin 351. This causes the other end of the driving arm 352 to push down the connecting rod 353. Due to the first and second ball joints 3531 and 3532 at each end of the connecting rod 353, the connecting rod 353 pushes down, driving the torsion arm 354 to rotate about the fifth pin 355, thereby driving the cutter 356 to press down synchronously, thus cutting the gold sheet. When the second motor 343 rotates clockwise and returns to its original position, the slicing mechanism 35 returns to its original position under the action of the fourth return torsion spring, and the cutter 356 is raised, ready for the next slicing operation.

[0123] Specifically, in this embodiment, the second driving mechanism includes a second guide rail 311, a second slide 32, and a second driving member 33. The second guide rail 311 is disposed on the second connecting frame 31, the second slide 32 is slidably connected to the second guide rail 311, and the second driving member 33 is also disposed on the second connecting frame 31. The second driving member 33 is connected to the second slide 32, so that the second driving member 33 drives the second slide 32 to move back and forth on the second guide rail 311.

[0124] Since the film feeding mechanism 34 is arranged on the second slide 32, when the second slide 32 moves back and forth on the second guide rail 311, it drives the film feeding mechanism 34 to move back and forth synchronously. Since the second guide rail 311 is arranged at an angle, when the second driving member 33 drives the second slide 32 to move on the second guide rail 311, it drives the film feeding mechanism 34 to move at an angle synchronously, so that the film outlet end of the film feeding mechanism 34 moves obliquely from one side of the flat embroidery machine head 1 to between the needle bar assembly 11 and the fabric, thereby preventing the frame of the flat embroidery machine head 1 from obstructing the movement of the film feeding mechanism 34, allowing the film outlet end of the film feeding mechanism 34 to move smoothly between the needle bar assembly 11 and the fabric, preventing the film outlet end of the film feeding mechanism 34 from colliding with the frame of the flat embroidery machine head 1, thereby ensuring the service life of the flat embroidery machine head 1 and the sequin embroidery device 3.

[0125] In actual implementation, both the first drive member 23 and the second drive member 33 in this application can be telescopic cylinders. The cylinder seat of the second drive member 33 is fixedly mounted on the second connecting frame 31, and the cylinder rod is connected to the second slide 32, so that when the cylinder rod is extended and retracted on the cylinder seat, the second slide 32 is driven to move back and forth on the second guide rail 311; the cylinder seat of the first drive member 23 is fixedly mounted on the first connecting frame 21, and the cylinder rod is connected to the first slide 22, so that when the cylinder rod is extended and retracted on the cylinder seat, the first slide 22 is driven to move back and forth on the first guide rail 211. The above-described contents can be implemented individually or in combination in various ways, and these variations are all within the scope of protection of the present invention.
