DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figures 1 to 9 The present invention discloses a gold sheet floating embroidery method and a gold sheet floating embroidery device. The gold sheet floating embroidery device comprises a flat embroidery head 1, an embroidery frame, a towel device 2 and a gold sheet embroidery device 3. The flat embroidery head 1 is provided with an upper thread, wherein the embroidery frame is provided below the flat embroidery head 1, the towel device 2 is provided at the rear side of the flat embroidery head 1, and the gold sheet embroidery device 3 is provided at the left or right side of the flat embroidery head 1. The cloth required for embroidery is laid on the embroidery frame. The cloth is in a taut state on the embroidery frame, and the cloth can be pressed at the non-embroidery part so that the upper and lower sides of the embroidery part of the cloth are in an overhead state, which is convenient for embroidering the cloth.

[0021] In actual use, the floating piece embroidery method includes the following steps: Step S1: Fix the fabric to be embroidered on the embroidery frame; Step S2: moving the needle bar assembly 11 of the flat embroidery machine head 1 to the initial lower needle position of the fabric; Step S3: moving the towel device 2 and the sequin embroidery device 3 to a designated position; Step S4: the towel device 2 swings, the needle bar assembly 11 moves down, and the upper thread passes through the fabric. After the upper thread is locked, the needle bar assembly 11 moves back. Step S5: moving the needle bar assembly 11 to the next needle position of the fabric; Step S6: the sequin embroidery device 3 feeds the sequins, and the needle bar assembly 11 inserts the needle again, so that the upper thread passes through the inner ring of the sequins and the fabric in sequence, and at the same time the towel device 2 swings to drive the upper thread to form a thread loop. After the upper thread is locked, the needle bar assembly 11 returns the needle; Step S7: Repeat steps S5 to S6 until the gold flake embroidery is completed on the fabric.

[0022] In the above process steps, the towel device 2 is used to drive the surface thread to form a thread loop, and the gold sheet is placed on the thread loop formed by the surface thread, so that the gold sheet can move along the axial direction of the thread loop, thereby achieving the effect of floating sheet embroidery, enriching the embroidery varieties and meeting the different needs of customers.

[0023] Specifically, in this embodiment, a thread clamp 12 is provided on the flat embroidery machine head 1, and the upper thread is loaded and transmitted 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 component disposed on the thread clamp 12 panel. The barrel is used to load the upper thread, and the upper thread transmitted from the barrel passes through the tension adjustment component and then is transmitted, so that the tension of the upper thread is adjusted by the tension adjustment component.

[0024] 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 needle insertion and needle return, the upper thread is driven to move synchronously to complete the embroidery work.

[0025] Specifically, in this embodiment, step S2 includes: the embroidery frame moves, the flat embroidery machine head 1 remains relatively fixed, and the needle bar assembly 11 moves to the initial lower needle position of the fabric. Similarly, step S5 includes: the embroidery frame moves, the flat embroidery machine head 1, the towel device 2 and the sequin embroidery device 3 remain relatively fixed, and the needle bar assembly 11 moves to the next lower needle position of the fabric.

[0026] In the present 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 plate embroidery device 3 remain relatively fixed, thereby realizing the movement of the needle bar assembly 11 between the needle positions on the fabric. At the same time, the relative positions of the towel device 2 and the gold plate embroidery device 3 and the flat embroidery machine head remain unchanged, which is convenient for subsequent embroidery.

[0027] The reason for adopting this movement mode is that the structures of the flat embroidery machine head 1, the towel device 2 and the gold-patch embroidery device 3 are relatively complicated compared with the embroidery frame structure. Therefore, the fabric is moved by the embroidery frame, and the flat embroidery machine head 1, the towel device 2 and the gold-patch embroidery device 3 remain relatively fixed, so that the needle bar assembly 11, the towel device 2 and the gold-patch 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.

[0028] Specifically, in this embodiment, step S3 includes: 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; 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.

[0029] 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 the designated positions on the flat embroidery machine head 1 during actual embroidery. Specifically, the swing end of the towel device 2 can be 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, so that during floating piece embroidery, the swing end of the towel device 2 swings to drive the upper thread to form a thread loop.

[0030] Then move the sheet outlet end of the gold sheet 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 gold sheet is delivered through the sheet outlet end of the gold sheet embroidery device 3, so that the gold sheet is located between the needle bar assembly 11 and the fabric, making it convenient for the needle bar assembly 11 to drive the surface thread to pass through the inner ring of the gold sheet.

[0031] 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 dislocated 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.

[0032] Specifically, in this embodiment, step S4 includes: 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 route of the needle bar assembly 11; Step S4.2: The gold sheet embroidery device 3 delivers the gold sheet to between the needle bar assembly 11 and the fabric; Step S4.3: the needle bar assembly 11 moves the needle, 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; Step S4.4: The bottom of the fabric is locked by the bottom thread to the top thread, and the needle bar assembly 11 is re-stitched; 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 needle thread.

[0033] Because at the initial needle insertion position of the fabric, initially, the swinging end of the towel device 2 and the sheet outlet end of the gold leaf embroidery device 3 are both located between the needle bar assembly 11 and the fabric, and are misaligned in the height direction, before the needle bar assembly 11 inserts 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 insertion route of the needle bar assembly 11; then the sheet outlet end of the gold leaf embroidery device 3 delivers the gold leaf to between the needle bar assembly 11 and the fabric; then the needle bar assembly 11 inserts the needle, and the needle bar assembly 11 drives the surface thread to move synchronously, so that the surface thread passes through the inner ring of the gold leaf and the fabric in turn, and the gold leaf is placed on the surface thread.

[0034] 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 drive the upper thread to form a loop.

[0035] Specifically, in this embodiment, step S6 includes: 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; Step S6.2: the needle bar assembly 11 moves the needle, 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; 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 sheets are sleeved on the thread loop; 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.

[0036] After the needle bar assembly 11 moves to the next needle position of the fabric, the next sequin is first sent between the needle bar assembly 11 and the fabric through the film outlet end of the sequin embroidery device 3; then the needle bar assembly 11 is inserted, 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 next sequin and the fabric in turn. 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 of the needle bar assembly 11, driving the part of the upper thread located above the fabric to form a first thread loop, so that both sequins are sleeved on the first thread loop.

[0037] After the portion of the upper thread located above the fabric forms the first thread loop, 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, and then the needle bar assembly 11 is back-stitched. Repeat steps S5 to S6, and the sequins through which the upper thread passes are named the first sequin, the second sequin, the third sequin..., and the ends of the upper thread fixed on the fabric are named the first end, the second end, the third end..., and the thread loops formed by the portion of the upper thread located above the fabric driven by the swing end of the towel device 2 are named the first thread loop, the second thread loop, the third thread loop..., and so on, until the floating piece embroidery of the sequins is completed on the fabric.

[0038] In the present application, the first and second ends of the surface thread are located above the fabric to form a first thread loop, the second and third ends are located above the fabric to form a second thread loop, and the third and fourth ends are located above the fabric to form a third thread loop. The first gold piece is sleeved on the first thread loop near the first end, and the first gold piece can move around the axis of the first thread loop; the second gold piece is sleeved on the first thread loop near the second end and the second thread loop near the first end at the same time, and the second gold piece can move around the axis of the first thread loop and the second thread loop within a certain range; the third gold piece is sleeved on the second thread loop near the second end and the third thread loop near the first end at the same time, and the third gold piece can move around the axis of the second thread loop and the third thread loop within a certain range, and so on, so that the gold piece embroidered on the fabric can achieve the effect of floating piece embroidery, enriching the embroidery varieties and meeting the different needs of customers.

[0039] When embroidering an embroidery product, it is usually necessary to embroider a large area on the fabric. Therefore, in this embodiment, when performing floating piece embroidery, step S7 includes: Step S7.1: repeating steps S5 to S6 to complete a row of gold flakes embroidery on the fabric; Step S7.2: Repeat step S7.1 to complete the floating piece embroidery of multiple columns of gold pieces on the fabric.

[0040] By repeating steps S5 to S6, a row of floating pieces is first embroidered on the fabric, and then the above steps are repeated to complete multiple rows of floating pieces embroidered on the fabric, thereby performing large-area embroidery on the fabric and completing the embroidery of the embroidery product. The use of this method for floating piece embroidery can, on the one hand, make the floating piece embroidery more regular and improve the quality of the embroidery product; on the other hand, it can reduce the relative moving distance between the embroidery frame and the flat embroidery machine head 1, thereby improving the embroidery efficiency and further improving the production efficiency.

[0041] 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, and 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.

[0042] When performing floating piece embroidery, the first driving mechanism is operated to drive the swinging mechanism to move, so that the end of the swinging mechanism away from the first driving mechanism moves to between the cloth and the needle bar assembly 11, so that when the needle bar assembly 11 drives the surface thread to cross the swinging end of the swinging mechanism, the surface thread forms a loop through the swinging end.

[0043] 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. 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.

[0044] Since the swing mechanism is arranged on the first slide 22, when the first slide 22 moves back and forth on the first guide rail 211, the swing mechanism is driven to move back and forth synchronously. Since the first guide rail 211 is arranged at an angle, when the first driving member 23 drives the first slide 22 to move on the first guide rail 211, the swing mechanism is driven to move at an angle synchronously, 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 hindering the movement of the swing mechanism, so that the swing end of the swing mechanism moves smoothly to 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, thereby ensuring the service life of the flat embroidery machine head 1 and the gold film embroidery device 3.

[0045] In this embodiment, the swing mechanism includes a swing motor 24, a swing seat 25 and a swing needle 26. The swing motor 24 is arranged on the first slide 22, the swing seat 25 is connected to the rotating shaft of the swing motor 24, and the swing needle 26 is arranged on the swing seat 25. When performing floating piece embroidery, the swing motor 24 is operated to make the rotating shaft of the swing motor 24 rotate bidirectionally by a certain angle, thereby driving the swing seat 25 to synchronously rotate bidirectionally by a certain angle, and then driving the swing needle 26 to swing by a certain angle, and the swing needle 26 acts on the upper thread to form a thread loop.

[0046] 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, and 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.

[0047] Therefore, when performing floating piece embroidery, the second driving mechanism is operated to drive the film feeding mechanism 34 to move, so that the end of the film feeding mechanism 34 away from the second driving mechanism moves to between the needle bar assembly 11 and the fabric, thereby delivering the gold film 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 surface thread to pass through the inner ring of the gold film.

[0048] Specifically, in actual implementation, the film feeding mechanism 34 includes a substrate 341, a first motor 342, a second motor 343, a first fork assembly 344, a second fork assembly 345 and a feeding bottom plate assembly 346. The first motor 342 and the second motor 343 are respectively fixedly mounted on the substrate 341, and the feeding bottom plate assembly 346 is arranged at the bottom of the substrate 341.

[0049] 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 move 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 move 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.

[0050] 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 .

[0051] The feeding bottom plate assembly 346 includes a bottom plate 3461 and a first guide slot plate 3462. The bottom plate 3461 is mounted on the base plate 341, and the first guide slot plate 3462 is mounted on the bottom plate 3461. A first guide slot is provided on the first guide slot plate 3462, and the other end of the first fork 3441 is inserted into the first guide slot. The first group of gold sheet strips passes through the bottom of the first guide slot, and the other end of the first fork 3441 is inserted into the inner hole of the gold sheet located in the first guide slot.

[0052] 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, so that the first fork 3441 pushes the first group of gold sheet belts forward by one gold sheet position, completing a picking operation.

[0053] In this application, "clockwise" and "counterclockwise" are both based on the front view ( Figure 2 ) The rotation direction of the viewing angle is taken as the reference direction, and the “clockwise” and “counterclockwise” that appear below are based on this direction.

[0054] In actual implementation, the first shift fork assembly 344 also includes a first reset torsion spring, which is sleeved on the first pin shaft 3442, and one end of the first reset 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 reset torsion spring is compressed; after completing a shifting operation, the first motor 342 rotates counterclockwise to return to its original position, and under the elastic force of the first reset torsion spring to restore its own deformation, the first shift fork 3441 retreats to its original position and waits for the next shifting operation.

[0055] Further, 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 provided on the back 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 provided on both sides of the base plate 341, and the second pin 3453 penetrates the base plate 341 and is rotatably connected to the base plate 341.

[0056] The driving torsion spring is sleeved on the second pin shaft 3453, and one end of the driving torsion spring is fixed on the base plate 341, and the other end is fixed on the first swing rod 3451. In the initial state, one end of the first swing rod 3451 abuts against the second swing arm 3431, and the driving torsion spring is compressed. One end of the second fork 3454 is rotatably connected to one end of the second swing rod 3452 through the third pin shaft 3455, and the second pin shaft 3453 connects the other end of the first swing rod 3451 with the other end of the second swing rod 3452. The driving torsion spring is sleeved on the second pin shaft 3453, and one end of the driving torsion spring is fixed on the base plate 341, and the other end is fixed on the first swing rod 3451.

[0057] The feeding bottom plate assembly 346 also includes a second guide slot plate 3463, which is mounted on the inclined surface of the first guide slot plate 3462, so that the second guide slot plate 3463 and the first guide slot plate 3462 are arranged in a stepwise distribution in height. A second guide slot is provided on the second guide slot plate 3463, and the other end of the second fork 3454 is inserted into the second guide slot. The second group of gold sheet strips passes through the bottom of the second guide slot, and the other end of the second fork 3454 is inserted into the inner hole of the gold sheet located in the second guide slot.

[0058] When feeding is required, the second motor 343 drives the second swing arm 3431 to rotate counterclockwise, so that the second swing arm 3431 is no longer in contact with 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 fork 3454 moves forward and rotates counterclockwise around the third pin shaft 3455, ensuring the plug-in state of the second fork and the inner hole of the gold sheet, thereby enabling the second fork 3454 to push the second group of gold sheet belts forward by one gold sheet position, completing a picking operation.

[0059] In actual implementation, the second fork assembly 345 also includes a second reset torsion spring, which is sleeved on the third pin 3455, and one end of the third reset torsion spring is fixed on the second swing rod 3452, and the other end is fixed on the second fork 3454. When the second fork assembly 345 performs a shifting operation, the second reset torsion spring is compressed.

[0060] After completing a paddle 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 paddle operation.

[0061] Furthermore, in this embodiment, the gold sheet embroidery device 3 further includes a slicing mechanism 35, which is arranged on the sheet feeding mechanism 34 and located at the sheet outlet end of the sheet feeding mechanism 34. When performing floating sheet embroidery, the sheet feeding mechanism 34 conveys the gold sheet belt, and when the gold sheet at the end of the gold sheet belt is conveyed to the sheet outlet end, the gold sheet at the end of the gold sheet belt is cut off from the adjacent gold sheet by the slicing mechanism 35, so that it becomes an independent gold sheet, so that when the needle bar assembly 11 is inserted, the upper thread is driven to pass through the gold sheet, and then a gold sheet is set on a thread loop of the upper thread.

[0062] In actual implementation, the output end of the second motor 343 is further provided with a third swing arm 3432, and the third swing arm 3432 is provided on the front 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. The first ball head 3531 and the second ball head 3532 are respectively mounted at both ends of the connecting rod 353. One end of the driving arm 352 abuts against the third swing arm 3432, and the other end is movably connected with the first ball head 3531 through a pin.

[0063] 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, and 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 further includes a fourth reset torsion spring, the fourth reset torsion spring is mounted on the fifth pin 355, one end of the fourth reset torsion spring is fixed to the torsion spring mounting block, and the other end is fixed to the base plate 341, and the cutter 356 is mounted on the end of the fifth pin 355.

[0064] When it is necessary to cut the gold sheet, the second motor 343 drives the third swing arm 3432 to rotate counterclockwise, and the third swing arm 3432 lifts one end of the driving arm 352 to rotate around the fourth pin 351, so that the other end of the driving arm 352 drives the connecting rod 353 to press down. Due to the first ball head 3531 and the second ball head 3532 provided at both ends of the connecting rod 353, the connecting rod 353 presses down, driving the torsion arm 354 to rotate around the fifth pin 355, thereby driving the cutter 356 to press down synchronously to cut 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 reset torsion spring, and the cutter 356 is lifted, waiting for the next slicing operation.

[0065] 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. 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.

[0066] 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, the film feeding mechanism 34 is driven 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, the film feeding mechanism 34 is driven 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 hindering the movement of the film feeding mechanism 34, so that the film outlet end of the film feeding mechanism 34 moves smoothly to 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 gold film embroidery device 3.

[0067] In actual implementation, the first driving member 23 and the second driving member 33 in the present application can both adopt telescopic cylinders. The cylinder seat of the second driving 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 driving 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 separately or in combination in various ways, and these variations are all within the protection scope of the present invention.
