[0042] Embodiment one

[0043] Based on the market demand for multi-color disc belt embroidery, on the basis of multi-color disc belt embroidery in the market, referring to Figures 1 to 15As shown, a multi-color disc belt embroidery device capable of automatic color changing and increasing the number of color changes is designed, which includes a disc belt embroidery head 5, a disc belt embroidery head 5 is provided with a disc belt embroidery head assembly 1, the disc belt embroidery head assembly 1 is provided with a belt disc 12, the color or specification of the disc belt on the belt disc 12 can be set differently, and here the multi-color disc belt embroidery color change is the whole replacement of the disc belt embroidery head assembly 1. Above the disc belt embroidery head 5 is provided with a disc belt embroidery head assembly color changing storage device 4 and a disc belt embroidery automatic replacement head assembly device. Among them, the disc belt embroidery head assembly color changing storage device 4 stores at least two disc belt embroidery head assemblies 1, and the disc belt embroidery automatic replacement head assembly device removes the disc belt embroidery head assembly 1 on the disc belt embroidery head 5 and places it in the disc belt embroidery head assembly color changing storage device 4, and then installs another disc belt embroidery head assembly 1 stored in the disc belt embroidery head assembly color changing storage device 4 on the disc belt embroidery head 5, to complete the automatic color change.

[0044] In this embodiment, the multi-color disc belt embroidery device can store multiple disc belt embroidery head assemblies 1 in the disc belt embroidery head assembly color changing storage device 4. Since the disc belt embroidery head assembly color changing storage device 4 is independent of the M-axis assembly, it is less restricted in space, and therefore theoretically can store more disc belt embroidery head assemblies 1, which is the basis for increasing the number of color changes.

[0045] In addition, the disc belt embroidery automatic replacement head assembly device can automatically act, including removing the disc belt embroidery head assembly 1 from the disc belt embroidery head assembly color changing storage device 4 and the disc belt embroidery head 5 and placing it on the disc belt embroidery head assembly color changing storage device 4 and the disc belt embroidery head 5, thereby realizing automatic color change and improving color change efficiency.

[0046] As shown, Figures 2 to 7 The disc belt embroidery head assembly 1 includes a belt disc support 11, a belt disc 12 detachably mounted on the belt disc support 11, and a belt disc assembly locking structure provided on the belt disc support 11. The belt disc assembly locking structure is used in cooperation with the belt disc assembly positioning structure to fix the disc belt embroidery head assembly 1. Whether the disc belt embroidery head assembly 1 is placed in the disc belt embroidery head assembly color changing storage device 4 or mounted on the disc belt embroidery head 5, it needs to be fixed, so the belt disc assembly locking structure is provided on the belt disc support 11, and the belt disc assembly positioning structure is provided on the disc belt embroidery head assembly color changing storage device 4 and the disc belt embroidery head 5. Since the belt disc support is provided with the belt disc assembly locking structure cooperating with the belt disc assembly positioning structure to fix the disc belt embroidery head assembly, it can ensure that the disc belt embroidery head assembly is locked with the disc belt embroidery head and the disc belt embroidery head assembly color changing storage device.

[0047] In this embodiment, the tape disc assembly locking structure includes locking sliders 13 slidingly arranged on both sides of the tape disc support 11. Taking the tape disc embroidery tape disc assembly color changing storage device 4 as an example, the tape disc assembly positioning structure is provided with a locking slot 4411, and the locking slider 13 cooperates with the locking slot. The locking slider can slide relative to the locking slot, and when cooperating with the locking slot, the entire tape disc embroidery tape disc assembly 1 is fixed to the tape disc embroidery tape disc assembly color changing storage device 4 or the tape disc embroidery machine head 5; when disengaging from the locking slot and being unlocked, the entire tape disc embroidery tape disc assembly 1 can be separated from the tape disc embroidery tape disc assembly color changing storage device 4 or the tape disc embroidery machine head 5. The way of controlling the sliding of the locking slider is mature in technology, and it is convenient to lock and unlock.

[0048] Further, the tape disc assembly locking structure further includes a locking pin hole 1111 arranged on the tape disc support 11 and corresponding to the locking slider 13. The axial direction of the locking pin hole 1111 is perpendicular to the sliding direction of the locking slider 13. Figures 13 to 15 As shown, taking the tape disc embroidery tape disc assembly color changing storage device 4 as an example, the tape disc assembly positioning structure includes a locking pin 441, the locking pin hole 1111 is used for cooperating with the locking pin 441, and the locking slot 4411 is arranged on the locking pin 441, perpendicular to the locking pin and penetrating through the locking pin radially. That is, after the locking pin 441 is inserted into the locking pin hole 1111, the locking slider 13 slides and cooperates with the locking slot, so as to realize the locking cooperation between the tape disc assembly locking structure and the tape disc assembly positioning structure. Therefore, after the tape disc embroidery tape disc assembly is placed in place, the locking pin is inserted into the locking pin hole, the tape disc embroidery tape disc assembly is locked with the tape disc embroidery tape disc assembly color changing storage device 4 or the tape disc embroidery machine head 5, without the need for other operations, which is convenient for color changing and improves the color changing efficiency.

[0049] Further, the locking slider 13 is connected with a slider reset spring, the locking slider 13 is provided with a spring mounting shaft 133, one end of the slider reset spring is mounted on the spring mounting shaft 133, the other end is connected with a spring positioning portion on the tape disc support 11, and the spring positioning portion can be a circular groove. That is, under the action of the slider reset spring, the locking slider 13 slides and cooperates with the locking slot, so as to realize the locking cooperation between the tape disc assembly locking structure and the tape disc assembly positioning structure. Therefore, when the tape disc embroidery tape disc assembly is placed on the tape disc embroidery tape disc assembly color changing storage device or the tape disc embroidery machine head, the slider reset spring can maintain the locking state of the tape disc assembly locking structure and the tape disc assembly positioning structure.

[0050] In order to ensure that the locking slider is aligned with the locking slot when it needs to be locked, a slider guide rail is arranged between the locking slider 13 and the tape disc support 11. Specifically, the slider guide rail includes a slider guide groove 131 arranged on the locking slider 13 and a guide pin 1121 arranged on the tape disc support 11, and the slider guide groove 131 cooperates with the guide pin 1121.

[0051] Further, the locking slider 13 is provided with a locking protrusion 132, and the locking protrusion 132 is provided with a limiting inclined surface 1321. Specifically, the locking slider 13 is in a rectangular structure as a whole, and the locking protrusion 132 protrudes upward from the rectangular main body, and the whole is in a right trapezoidal or isosceles trapezoidal shape, which can form one limiting inclined surface through the inclined waist, or can form two limiting inclined surfaces. Since the locking slot 4411 is arranged on the locking pin 441 in a substantially rectangular shape, the length of the lower base of the trapezoid is greater than the width of the locking slot 4411, and can cooperate with the locking slot port to form a limit. In this way, under the action of the slider return spring, the locking slider 13 slides and cooperates with the locking slot, but will not be separated from the locking slot, and only the reverse movement can be separated from the locking slot.

[0052] The disc belt embroidery automatic replacement disc assembly device adopts a grabbing manipulator 2 to grab the disc belt embroidery disc assembly 1. Only when the disc assembly locking structure is unlocked, the disc belt embroidery disc assembly 1 can be transferred away. In order to realize the unlocking of the disc assembly locking structure, the locking slider 13 needs to overcome the resistance of the slider return spring to realize the separation of the locking protrusion 132 on the locking slider from the locking slot 4411. Therefore, the pawl of the grabbing manipulator can be used to unlock the disc assembly locking structure, without the need for manual unlocking or additional unlocking mechanism on the grabbing manipulator. That is, the pawl of the grabbing manipulator drives the locking slider 13 to move while grabbing the disc belt embroidery disc assembly 1, so as to unlock the disc assembly locking structure, and the disc belt embroidery disc assembly 1 is also grabbed after being unlocked.

[0053] Corresponding to the pawl of the grabbing manipulator, the end of the locking slider 13 and the side surface of the disc support are provided with a grabbing recess, and the grabbing recess cooperates with the pawl of the manipulator. That is, the lower grabbing recess 1114 is arranged on the locking slider, and the upper grabbing recess 1114 is arranged on the side surface of the disc support. Due to the action of the slider return spring, the lower grabbing recess 1114 protrudes outward from the upper grabbing recess 134 in the free state. Therefore, when the grabbing manipulator 2 grabs the disc belt embroidery disc assembly 1, the pawl of the grabbing manipulator first acts on the lower grabbing recess, drives the locking slider 13 to move inward, and when the lower grabbing recess 134 and the upper grabbing recess 1114 are flush, the disc assembly locking structure has been unlocked, and the pawl of the grabbing manipulator is just grabbed on the upper grabbing recess. In this way, the grabbing manipulator grabs the disc belt embroidery disc assembly while unlocking the disc assembly locking structure, and the grabbing manipulator directly transfers the disc belt embroidery disc assembly after being grabbed, thereby improving the color changing efficiency.

[0054] It can be understood that the positions of the disc assembly locking structure and the disc assembly positioning structure can be interchanged.

[0055] When the grabbing manipulator 2 grabs the disc belt embroidery disc assembly 1, the relative position of the two must be ensured first, so that the grabbing recesses can be matched in place with the manipulator claws. Therefore, the grabbing manipulator 2 is provided with a positioning pin 22, and a corresponding positioning pin hole 1112 is arranged on the disc belt embroidery disc assembly 1 to cooperate with the positioning pin 22. Of course, in order to ensure the accuracy of positioning, two positioning pin holes 1112 and two positioning pins 22 are arranged to limit the degrees of freedom of the disc belt embroidery disc assembly 1 and the grabbing manipulator. After the positioning pin 22 is inserted into the positioning pin hole 1112, the manipulator claws can act on the lower grabbing recess and the upper grabbing recess at the same time.

[0056] It can be understood that the positions of the positioning pin hole 1112 and the positioning pin 22 can also be interchanged.

[0057] With reference to the prior art, the disc belt support 11 is provided with a presser foot structure, which includes a presser foot slider 15 that can slide linearly up and down on the disc belt support, a presser foot 16 mounted on the presser foot slider, and a presser foot guide rail arranged between the disc belt support 11 and the presser foot slider 15. The presser foot slider 15 is inserted with a presser foot driving member on the M-axis assembly, and the presser foot slider is driven by the presser foot driving member to move up and down.

[0058] In addition, the disc belt support 11 is provided with a guide shaft 18, and a linear bearing 153 is arranged between the presser foot slider 15 and the guide shaft 18. The linear bearing 153 is fixed on the presser foot slider 15, and the guide shaft 18 is fixed on the disc belt support 11. The presser foot slider 15 is further provided with a belt embroidery pressing piece 17, and a disc belt passage is arranged between the belt embroidery pressing piece 17 and the presser foot slider 15 for the disc belt to pass through. The back surface of the presser foot slider 15 is provided with a middle recess 151 in the middle, and the presser foot slider 15 is provided with a disc belt passing groove 154 below the middle recess 151, and the belt embroidery pressing piece 17 passes through the disc belt passing groove 154.

[0059] In this embodiment, the presser foot driving member includes a driving block and a driving pin. The two ends of the driving pin extend outward to the two sides of the driving block and protrude from the side surface of the driving block. The left and right sides of the middle recess 151 are provided with insertion slots 152 that penetrate through the back surface of the presser foot slider. In this way, when the disc belt embroidery automatic disc replacement assembly device installs the disc belt embroidery disc assembly 1 on the disc belt embroidery machine head 5, the driving pin is inserted into the insertion slot. When the disc belt embroidery automatic disc replacement assembly device separates the disc belt embroidery disc assembly 1 from the disc belt embroidery machine head 5, the driving pin is pulled out of the insertion slot. Therefore, the combination and separation of the presser foot driving member and the presser foot slider are facilitated.

[0060] Further, a trumpet mouth structure can be arranged at the height position of the middle recess 151 corresponding to the insertion slot, and the opening end of the insertion slot is provided with a rounded corner to facilitate the insertion of the driving pin into the insertion slot.

[0061] When the disc-belt embroidery automatic replacement of the belt disc assembly device separates the disc-belt embroidery belt disc assembly 1 from the disc-belt embroidery machine head 5, the slot on the presser foot slider is separated from the driving pin, at this time the presser foot slider is not affected by external force, and will automatically fall under the action of gravity. When the disc-belt embroidery belt disc assembly 1 and the disc-belt embroidery machine head 5 are recombined, the position of the slot and the driving pin cannot be matched. In order to solve this problem, the high position of the belt disc support 11 corresponding to the presser foot slider 15 is provided with a magnet 19 for adsorbing and fixing the presser foot slider 15, and the magnet 19 is fixed on the magnet fixing plate 191. In this way, when the presser foot slider is in the high position, the slot on the presser foot slider is separated from the driving pin, and under the action of the magnet, the presser foot slider can be kept in the high position. When the disc-belt embroidery belt disc assembly 1 and the disc-belt embroidery machine head 5 are recombined, the position of the slot and the driving pin is still matched, so that the driving pin can be normally inserted into the slot.

[0062] The disc-belt embroidery automatic replacement of the belt disc assembly device needs to ensure that the disc belt on the belt disc is not loose during the transfer of the disc-belt embroidery belt disc assembly 1 between the disc-belt embroidery belt disc assembly color changing storage device 4 and the disc-belt embroidery machine head 5, and when the disc-belt embroidery belt disc assembly 1 is stored in the disc-belt embroidery belt disc assembly color changing storage device 4. Therefore, the disc-belt embroidery belt disc assembly 1 is also provided with a disc belt locking structure 14, which includes a transversely extending needle shaft 141, a spring pin 143 perpendicular to the needle shaft, a needle spring 144 mounted on the spring pin, and a lock spring 142 connected to the needle shaft. The belt disc support 11 is provided with a spring pin mounting hole 1118, and the spring pin 143 passes through the spring pin mounting hole 1118, wherein the head end of the spring pin 143 is provided with a limiting cap, and the tail end is also provided with a limiting cap. The needle spring 144 is sleeved on the spring pin 143, and the two ends abut against the limiting cap. The lock spring 142 is a U-shaped structure, and the bent parts 1421 at both ends are movably connected to the radial through hole on the needle shaft, and a disc belt passing gap is formed between the lock spring 142 and the needle shaft. The spring pin mounting hole 1118 and the radial through hole on the needle shaft are perpendicular and intersected and communicated, and a slope matching structure is provided between the bent part of the lock spring 142 and the spring pin 143, so that in the free state, the disc belt passing gap is narrowed, the disc belt is clamped, and the disc belt is prevented from being loose and disorderly.

[0063] In this embodiment, the reel support 11 comprises a support upper fixing block 111, a lock block lower cover plate 112 and a support arm 113. The support upper fixing block 111 is provided with a slide groove 1113 on the bottom of the left and right sides, and the lock sliding block 13 is arranged in the slide groove and can slide along the slide groove.

[0066] Further, the clamping jaw driver 25 comprises a clamping jaw driving cylinder 251, a cylinder connecting block one 252 and a cylinder connecting block two 253, the clamping jaw driving cylinder body is fixed with the cylinder connecting block one 252 and connected with one of the clamping jaw sliders, the top rod of the clamping jaw driving cylinder is fixed with the cylinder connecting block two 253 and connected with the other clamping jaw slider. The top rod is connected with a top rod connecting block 254, and the top rod connecting block is connected with the cylinder connecting block two 253. Through the structure of the above-mentioned clamping jaw driver 25, when the clamping jaw driving cylinder 251 drives the top rod to pop out, the two clamping jaw sliders 242 are opened, and when the clamping jaw driving cylinder 251 drives the top rod to retract, the two clamping jaw sliders 242 are closed.

[0067] Further, the left and right sides of the clamping jaw guide rail 241 are provided with guide rail limiting plates 243 for limiting the maximum opening position of the two clamping jaw sliders 242. The clamping jaw 23 comprises a clamping jaw body and a grabbing pin 231 installed on the clamping jaw body. The grabbing pin 231 is perpendicular to the positioning pin 22, after the positioning pin is inserted into the positioning pin hole 1112, the grabbing pins 231 on the two clamping jaws 231 correspond to the positions of the lower and upper grabbing recesses, at this time, the clamping jaw driving cylinder 251 drives the top rod to retract, the two clamping jaw sliders 242 are closed, the locking slider 13 is first driven to move inward to realize the unlocking of the disc belt embroidery disc assembly locking structure and the disc belt embroidery disc assembly positioning structure, and then the disc belt embroidery disc assembly 1 is clamped.

[0068] Further, the two positioning pins 22 are arranged side by side, the tail end of the positioning pin is arranged on the positioning pin fixing block. The head end of the positioning pin is provided with a tapered head 221 to facilitate the insertion of the positioning pin into the positioning pin hole. The tail end of the positioning pin is provided with a tapered limiting portion 222 to limit the positioning pin after being inserted into the positioning pin hole to a certain position.

[0069] Further, the manipulator body 21 is connected with a manipulator rotating shaft 26, the manipulator rotating shaft 26 is used to drive the grabbing manipulator 2 to rotate. The swing arm mechanism 3 cannot completely align the grabbing manipulator 2 with the disc belt embroidery disc assembly 1 only by swinging, therefore the swing arm mechanism 3 can also drive the manipulator rotating shaft 26 to rotate and drive the grabbing manipulator 2 to rotate.

[0070] According to the above discloses the disc belt embroidery disc assembly, the disc belt embroidery disc assembly is provided with the belt disc assembly locking structure. Therefore, the calipers clamp the belt disc assembly at the same time, the disc belt embroidery disc assembly locking structure is unlocked, so that the disc belt embroidery disc assembly can be transferred away.

[0071] The disc belt embroidery disc assembly must be positioned by the grabbing manipulator, and the disc belt embroidery disc assembly is basically not displaced, so that the disc belt assembly positioning structure and the disc belt assembly locking structure are aligned, but the conventional manipulator is difficult to achieve. Since the disc belt embroidery disc assembly is provided with a positioning pin hole, the disc belt embroidery disc assembly grabbing manipulator is provided with a positioning pin matched with the positioning pin hole, so that the disc belt embroidery disc assembly and the grabbing manipulator are positioned before the calipers clamp the disc belt embroidery disc assembly. On the one hand, the calipers and the disc belt embroidery disc assembly are aligned, and on the other hand, the disc belt embroidery disc assembly is basically not displaced after the calipers clamp the disc belt embroidery disc assembly. The disc belt embroidery disc assembly is transferred to the disc belt embroidery disc assembly color changing storage device and the disc belt embroidery machine head corresponding position by the grabbing manipulator, so that the disc belt assembly positioning structure and the disc belt assembly locking structure are aligned.

[0072] As shown in Figure 10 and Figure 11 , the swing arm mechanism 3 includes a swing arm bracket 31 and a swing arm body 32, the tail end of the swing arm body is fixed with a swing arm rotating shaft, the swing arm rotating shaft is rotationally supported on the swing arm bracket 31, and the swing arm bracket 31 is provided with a swing arm driving assembly 33 for driving the swing arm body 32 to swing and driving the grabbing manipulator 2 to rotate.

[0073] In this embodiment, the swing arm driving assembly 33 includes a swing arm driving motor 331, a worm gear 333 fixed to the swing arm rotating shaft, and a worm 332 connected to the output shaft of the swing arm driving motor. The worm 332 is engaged with the worm gear 333, the head end of the swing arm body is provided with a manipulator joint driving shaft 36, and the output shaft of the swing arm driving motor 331 and the manipulator joint driving shaft 36 are provided with a swing arm transmission part. Moreover, the manipulator joint driving shaft 36 is fixed with the manipulator rotating shaft 26, and the two can be fixed by a clamp structure and rotate synchronously.

[0074] Specifically, the swing arm transmission part includes a first driving pulley 361 mounted on the swing arm rotating shaft and a first driven pulley 362 mounted on the manipulator joint driving shaft. The first driving pulley 361 and the first driven pulley 362 are connected by a first synchronous belt. It can be understood that the first synchronous belt can also be connected with a first tension pulley 363. In this way, when the swing arm body drives the grabbing manipulator to swing, the manipulator joint driving shaft 36 is driven to rotate through the swing arm transmission part, and then the grabbing manipulator 2 is driven to rotate.

[0075] Specifically, the swing arm support 31 comprises a left support 311, a right support 312, and a volute 313 arranged between the left support and the right support, both ends of the swing arm rotation shaft are correspondingly rotationally supported on the left support and the right support, and the worm gear is arranged in the volute. The swing arm body 32 comprises a left swing arm shell 321 and a right swing arm shell 322, and the swing arm transmission component is arranged between the left swing arm shell 321 and the right swing arm shell 322.

[0076] Further, the worm 332 is installed on a worm shaft, and the hand wheel 334 is connected to the worm shaft. In this way, the worm can also be driven to rotate by the hand wheel.

[0077] Due to the arrangement of the swing arm transmission component, the rotation of the swing arm body 32 and the swing arm transmission component can be coordinated, so that when the swing arm body 32 is swung downward to the position, the positioning pin 22 on the grabbing manipulator 2 is aligned with the positioning pin hole 1112 of the disc embroidery band disc assembly 1 on the disc embroidery machine head 5, or when the swing arm body is swung upward to the position, the positioning pin 22 is aligned with the positioning pin hole 1112 of the disc embroidery band disc assembly 1 on the disc embroidery band disc assembly color changing storage device 4. At this time, the grabbing manipulator 2 still needs to perform a front and back movement to enable the positioning pin 22 on the grabbing manipulator 2 to be inserted into the positioning pin hole 1112 of the disc embroidery band disc assembly 1. Therefore, the disc embroidery automatic band disc assembly changing device further comprises a beam support 34, a front and back linear guide rail 35 is arranged between the beam support 34 and the swing arm support 31, and the swing arm front and back driver drives the swing arm support and the swing arm body to move forward and backward along the front and back linear guide rail 35. The swing arm front and back driver is a front and back driving cylinder, and of course, a linear motor or the like can also be used.

[0078] A conventional mechanical arm needs to be provided with an X-direction driving mechanism, a Y-direction driving mechanism, a Z-direction driving mechanism, and an R-direction driving mechanism to ensure that the disc embroidery band disc assembly is accurately conveyed to the position after being grabbed by the grabbing manipulator, so as to ensure that the band disc assembly positioning structure is aligned with the band disc assembly locking structure. Due to the need for cooperation of multiple mechanisms and the large number of mechanisms, the structure is relatively complex, and the action is relatively large, which causes the color changing efficiency to be relatively low. The swing arm mechanism adopted in the embodiment only needs to drive the swing arm body to swing and the grabbing manipulator to rotate, and the swing arm body is driven to move forward and backward when necessary, which is less than the action of the conventional mechanical arm, and the swing of the swing arm body is relatively short in stroke. Moreover, since the swing of the swing arm body and the rotation of the grabbing manipulator share a swing driving assembly, the structure is simpler. Therefore, the combination of less action, short stroke, and simple structure can significantly improve the color changing efficiency.

[0079] Since the number of disc embroidery band disc assemblies stored in the disc embroidery band disc assembly color changing storage device determines the number of colors that can be changed, the number of disc embroidery band disc assemblies stored in the disc embroidery band disc assembly color changing storage device should be as large as possible.

[0080] As Figures 13 to 15 shown, in order to increase the number of color changing, the disc tape embroidery disc assembly color changing storage device 4 includes a rack 41, a rotating disc 42 provided on the rack, a rotating disc driving assembly 43 for driving the rotating disc to rotate, a rack guide rail 45 extending along the axis of the rotating disc, and a rack translation driving assembly for driving the rack 41 to move horizontally along the rack guide rail 45.

[0081] Among them, the rotating disc 42 is circumferentially distributed with at least two positioning plates 44, the positioning plates 44 extend along the axis of the rotating disc and are provided with at least two disc assembly positioning structures along the extension direction. The disc assembly positioning structure and the disc assembly locking structure fix the disc tape embroidery disc assembly 1 on the positioning plate 44, and when the rotating disc rotates and the rack translates, the disc tape embroidery disc assembly 1 is fixed reliably. Only when the disc tape embroidery automatic disc assembly replacement device takes the disc tape embroidery disc assembly 1, the disc assembly locking structure and the disc assembly positioning structure are unlocked, the disc tape embroidery disc assembly 1 can be taken off from the disc tape embroidery disc assembly color changing storage device 4.

[0082] Because the position of the disc tape embroidery automatic disc assembly replacement device taking the disc tape embroidery disc assembly color changing storage device 4 is fixed, it can be called color changing position here. When color changing is needed, the rotating disc driving assembly 43 drives the rotating disc 42 to rotate, or the rack translation driving assembly drives the rack 41 to move horizontally along the rack guide rail 45, which can make a corresponding disc tape embroidery disc assembly 1 sent to the color changing position of the disc tape embroidery disc assembly color changing storage device 4.

[0083] The above technical solution can store disc tape embroidery disc assemblies 1 in the axial direction and circumferential direction of the rotating disc 42, and the number of disc tape embroidery disc assemblies 1 stored in the disc tape embroidery disc assembly color changing storage device 4 is greatly increased. Of course, due to space limitations, two disc tape embroidery disc assemblies 1 are usually arranged on the positioning plate in the axial direction, and three disc tape embroidery disc assemblies 1 are arranged along the circumference of the rotating disc, that is, the disc tape embroidery disc assembly color changing storage device 4 stores six disc tape embroidery disc assemblies 1.

[0084] In the embodiment, the disc assembly positioning structure includes a locking pin 441 matched with the locking pin hole, and the locking pin is provided with a locking groove 4411 matched with the locking part. And the locking pin 441 is also provided with the same structure as the taper head 221 and the taper face limiting part 222 of the positioning pin, so as to facilitate the cooperation with the locking pin hole.

[0085] Specifically, the rotating disc 42 comprises a central rotating shaft 421, a spoke fixed to the central rotating shaft, the spoke comprises a shaft sleeve 422 and at least two spoke claws 423 evenly distributed along the circumference of the shaft sleeve, and the positioning plate 44 is fixed to the spoke claw 423. The spoke claw 423 comprises an arc-shaped part 4231 connected with the shaft sleeve and a fixed part 4232 connected with the arc-shaped part, and the fixed part is provided with a positioning fixed surface, and the fixed plate is rectangular and is fixed with the positioning fixed surface by screws. This is to ensure that the positioning plate does not affect the grabbing manipulator to grab the disc belt embroidery disc assembly 1 after the rotating disc is rotated to the position.

[0086] Among them, one spoke is arranged on each of the left side, the right side and the middle of the central rotating shaft. In this way, the positioning plate is fixed on the left side, the right side and the middle, so as to ensure that the positioning plate is fixed stably and reliably.

[0087] Specifically, the rotating disc driving assembly 43 comprises a rotating disc driving motor 431 and a rotating transmission part connecting the output shaft of the rotating disc driving motor and the central rotating shaft. The rotating transmission part comprises a second driving pulley 432 installed on the output shaft of the rotating disc driving motor, a second driven pulley 433 fixed to the central rotating shaft, and a second synchronous belt connecting the second driving pulley and the second driven pulley.

[0088] As an embodiment, the rack translation driving assembly comprises a rack driving motor and a linear transmission part, which converts the rotary motion of the rack driving motor into the linear motion of the rack. Among them, the linear transmission part is a screw nut part.

[0089] Specifically, the rack 41 comprises side support plates arranged side by side, the rotating disc 42 is arranged between the two side support plates, and the rack guide rail 45 is connected with the side support plates. In addition, bearings are arranged on the side support plates to rotatably support the central rotating shaft. The rotating disc driving assembly is arranged on the inner side of the side support plates, wherein the rotating disc driving motor 431 is fixed to the inner side of the side support plates by a motor fixing stud 435, one end of the driving pulley shaft is connected with the motor output shaft, and the other end is rotatably supported on the bearing installed on the side support plates. A second tension pulley 434 is also installed on the side support plates for tensioning the second synchronous belt.
