Description

TECHNICAL FIELD

[0001] One or more embodiments of the present specification relate to the technical field of computerized embroidery machines, and in particular to a hybrid head structure of a computerized embroidery machine. BACKGROUND

[0002] A computerized embroidery machine is an automated device controlled by a computer, used for embroidery on cloth or other materials. It can automatically complete complex embroidery work according to pre-designed patterns and instructions. Compared with traditional hand embroidery, computerized embroidery machines can greatly improve production efficiency and ensure the consistency of patterns and the stability of quality for each product. With the continuous enrichment of embroidery products, consumers have increasingly high requirements for the types of embroidery products, and the market requires the combination of flat embroidery, ribbon embroidery, and rope embroidery processes in embroidery machines. Therefore, existing computerized embroidery machines usually set up both flat embroidery heads and disc ribbon embroidery heads (disc ribbon embroidery is a combination of rope embroidery and ribbon embroidery).

[0003] However, the existing computerized embroidery machine drives the flat embroidery head and the disc ribbon embroidery head through only one embroidery needle drive shaft. When the disc ribbon embroidery head is working, the embroidery needle drive shaft not only drives the embroidery needle of the disc ribbon embroidery head to move, but also drives some parts of the flat embroidery head to move, causing the parts of the flat embroidery head to wear out. Similarly, when the flat embroidery head is working, the embroidery needle drive shaft not only drives the embroidery needle of the flat embroidery head to move, but also drives some parts of the disc ribbon embroidery head to move, causing the parts of the disc ribbon embroidery head to wear out.

[0004] In summary, the existing hybrid head structure of a computerized embroidery machine has a structure of an embroidery needle drive shaft that causes severe wear of the head parts, thereby shortening the service life of the head of the computerized embroidery machine. SUMMARY

[0073] Embodiment 1:

[0074] A hybrid machine head structure of a computerized embroidery machine, comprising: Figure 1 and Figure 2As shown, the mixed machine head structure comprises: at least one disc band embroidery machine head 100, at least one flat embroidery machine head 200, a rotating shuttle assembly 500, a first embroidery needle driving shaft 300, a second embroidery needle driving shaft 400, a rotating shuttle driving shaft, a power device one, a power device two and a power device three.

[0075] The rotating shuttle assembly 500 is arranged below the disc band embroidery machine head 100 or the flat embroidery machine head 200.

[0076] The first embroidery needle driving shaft 300 is connected with all the disc band embroidery machine heads 100.

[0077] The second embroidery needle driving shaft 400 is connected with all the flat embroidery machine heads 200.

[0078] The rotating shuttle driving shaft is connected with all the rotating shuttle assemblies 500.

[0079] The power device one is connected with the first embroidery needle driving shaft 300 and is used to drive the first embroidery needle driving shaft 300 to rotate.

[0080] The power device two is connected with the second embroidery needle driving shaft 400 and is used to drive the second embroidery needle driving shaft 400 to rotate.

[0081] The power device three is connected with the rotating shuttle driving shaft and is used to drive the rotating shuttle driving shaft to rotate.

[0082] In this embodiment, two embroidery needle driving shafts are arranged, one first embroidery needle driving shaft 300 and one second embroidery needle driving shaft 400. When the disc band embroidery machine head 100 works, only the first embroidery needle driving shaft 300 is used to drive the embroidery needle of the disc band embroidery machine head 100 to move, at this time, the flat embroidery machine head 200 does not need to move, that is, the working of the disc band embroidery machine head 100 will not cause any part of the flat embroidery machine head 200 to be abraded. Similarly, when the flat embroidery machine head 200 works, only the second embroidery needle driving shaft 400 is used to drive the embroidery needle of the flat embroidery machine head 200 to move, at this time, the disc band embroidery machine head 100 does not need to move, that is, the working of the flat embroidery machine head 200 will not cause any part of the disc band embroidery machine head 100 to be abraded.

[0083] Since the disc band embroidery machine head 100 in this embodiment is driven by the first embroidery needle driving shaft 300 and the flat embroidery machine head 200 is driven by the second embroidery needle driving shaft 400, the working of the disc band embroidery machine head 100 will not cause any part of the flat embroidery machine head 200 to be abraded and the working of the flat embroidery machine head 200 will not cause any part of the disc band embroidery machine head 100 to be abraded, so that the abrasion degree of the machine head parts can be effectively reduced under the same working time, and the service life of the computer embroidery machine head can be effectively prolonged.

[0084] However, the rotating hook driving shaft and the embroidery needle driving shaft in the prior art are connected through a synchronous belt. The working principle is that the driving motor drives the embroidery needle driving shaft to rotate, thereby enabling the machine head to work, and the embroidery needle driving shaft drives the rotating hook driving shaft to rotate synchronously through the synchronous belt, thereby enabling the rotating hook assembly to work synchronously.

[0085] If two embroidery needle driving shafts are provided, the first embroidery needle driving shaft 300 is connected to the rotating hook driving shaft through a first synchronous belt, and the second embroidery needle driving shaft 400 is connected to the rotating hook driving shaft through a second synchronous belt. In this way, when the first embroidery needle driving shaft 300 rotates, it drives the rotating hook driving shaft to rotate synchronously through the first synchronous belt, and the rotating hook driving shaft drives the second embroidery needle driving shaft 400 to rotate synchronously through the second synchronous belt. The rotation of the second embroidery needle driving shaft 400 still causes the parts of the flat embroidery machine head 200 to rotate and wear. Therefore, in the mixed machine head structure of the computer embroidery machine, merely providing two embroidery needle driving shafts cannot reduce the wear of the machine head parts.

[0086] Therefore, the mixed machine head structure of the computer embroidery machine can prevent the parts of the flat embroidery machine head from being worn when the disc embroidery machine head works, and prevent the parts of the disc embroidery machine head from being worn when the flat embroidery machine head works, thereby effectively reducing the wear of the machine head parts under the same working time, and finally effectively prolonging the service life of the machine head of the computer embroidery machine.

[0087] In addition, in the mixed machine head structure of the computer embroidery machine, the rotating hook driving shaft is driven by the power device three instead of being synchronously rotated with the embroidery needle driving shaft, so that the rotating hook driving shaft can be selectively operated or not operated according to different embroidery schemes. When the rotating hook driving shaft needs to rotate, the power device three is used to drive the rotating hook driving shaft to rotate; when the rotating hook driving shaft does not need to rotate, the power device three is used to stop the rotating hook driving shaft from rotating. This setting enables the rotating hook assembly 500 to stop rotating when it does not need to work, thereby avoiding unnecessary wear of the rotating hook assembly 500 and improving the service life of the rotating hook assembly 500.

[0088] Further, as shown in Figure 3 and Figure 4 the power device one of the embodiment comprises a bearing one 310, a pulley one A 320, a driving motor one, a pulley one B 330 and a driving belt one.

[0089] The movable part of bearing one 310 is connected with the first embroidery needle driving shaft 300. The fixed part of bearing one 310 is connected with the embroidery machine frame 900 through bearing mounting frame one 340. According to actual use requirements, a plurality of bearing ones 310 can be arranged on the first embroidery needle driving shaft 300. The bearing one 310 supports the first embroidery needle driving shaft 300 and allows the first embroidery needle driving shaft 300 to rotate.

[0090] The inner ring part of pulley one A 320 is connected with the first embroidery needle driving shaft 300. According to actual use requirements, one or two or more pulley one A 320 can be arranged on the first embroidery needle driving shaft 300.

[0091] The inner ring part of pulley one B 330 is connected with the output shaft of the driving motor one. If there are several pulley one A 320, there are corresponding several pulley one B 330. If there are several pulley one B 330, there are corresponding several driving motor one. The driving motor one is connected with the embroidery machine frame 900 through the motor mounting frame one 350. The driving motor one is electrically connected with the controller, and the running state of the driving motor one can be controlled through the controller (for example, the driving motor one is controlled to start, or the driving motor one is controlled to stop, or the rotating speed of the driving motor one is adjusted, etc.).

[0092] The driving belt one connects the outer ring part of pulley one A 320 and the outer ring part of pulley one B 330. The embroidery machine frame 900 is also provided with a cavity one 910 allowing the driving belt one to pass through. The driving belt one, pulley one A 320, pulley one B 330 and driving motor one cooperate to provide power for the rotation of the first embroidery needle driving shaft 300.

[0093] Working principle: the driving motor one drives the pulley one B 330 to rotate, the pulley one B 330 drives the driving belt one to rotate, the driving belt one drives the pulley one A 320 to rotate, and the pulley one A 320 drives the first embroidery needle driving shaft 300 to rotate. When there are a plurality of driving motor ones, only the working frequency of the plurality of driving motor ones needs to be the same.

[0094] The power device one of the embodiment can provide sufficient driving force for the first embroidery needle driving shaft 300, so that the first embroidery needle driving shaft 300 can stably and smoothly rotate.

[0095] Further, as shown in Figure 5 and Figure 6 , the power device two of the embodiment includes: bearing two 410, pulley two A 420, driving motor two, pulley two B 430 and driving belt two.

[0096] The movable part of bearing two 410 is connected with the second embroidery needle driving shaft 400. The fixed part of bearing two 410 is connected with the embroidery machine rack 900 through bearing mounting rack two 440. According to actual use requirements, a plurality of bearing two 410 can be arranged on the second embroidery needle driving shaft 400. Bearing two 410 supports the second embroidery needle driving shaft 400 and allows the second embroidery needle driving shaft 400 to rotate.

[0097] The inner ring part of pulley two A 420 is connected with the second embroidery needle driving shaft 400. According to actual use requirements, one or two or more pulley two A 420 can be arranged on the second embroidery needle driving shaft 400.

[0098] The inner ring part of pulley two B 430 is connected with the output shaft of the driving motor two. If there are several pulley two A 420, there are corresponding several pulley two B 430. If there are several pulley two B 430, there are corresponding several driving motor two. The driving motor two is connected with the embroidery machine rack 900 through the motor mounting rack two 450. The driving motor two is electrically connected with the controller, and the running state of the driving motor two can be controlled through the controller (such as controlling the driving motor two to start, or controlling the driving motor two to stop, or adjusting the rotating speed of the driving motor two, etc.).

[0099] The driving belt two connects the outer ring part of pulley two A 420 and the outer ring part of pulley two B 430. The embroidery machine rack 900 is also provided with a cavity two 920 allowing the driving belt two to pass through. The driving belt two, pulley two A 420, pulley two B 430 and driving motor two cooperate to provide power for the rotation of the second embroidery needle driving shaft 400.

[0100] Working principle: the driving motor two drives the pulley two B 430 to rotate, the pulley two B 430 drives the driving belt two to rotate, the driving belt two drives the pulley two A 420 to rotate, and the pulley two A 420 drives the second embroidery needle driving shaft 400 to rotate. When there are multiple driving motor two, only the working frequency of multiple driving motor two needs to be the same.

[0101] The power device two of the embodiment can provide sufficient driving force for the second embroidery needle driving shaft 400, so that the second embroidery needle driving shaft 400 can rotate stably and smoothly.

[0102] Further, as shown in Figure 7 The flat embroidery machine head 200 in the embodiment is provided with a avoiding space allowing the first embroidery needle driving shaft 300 to pass through along the length direction of the driving shaft, and the avoiding space is surrounded by a supporting cover 360. The supporting cover 360 is connected and fixed with the embroidery machine rack 900, and plays a role of shielding and protecting the first embroidery needle driving shaft 300.

[0103] The first embroidery needle driving shaft 300 is not in contact with the flat embroidery machine head 200, and the flat embroidery machine head 200 is not affected when the first embroidery needle driving shaft 300 drives the disc tape embroidery machine head 100 to work, so that the parts of the flat embroidery machine head 200 are not abraded.

[0104] Further, the shell of the disc tape embroidery machine head 100 in the embodiment is provided with a through hole allowing the second embroidery needle driving shaft 400 to pass through. The diameter of the through hole is greater than the diameter of the second embroidery needle driving shaft 400.

[0105] The second embroidery needle driving shaft 400 is not in contact with the disc tape embroidery machine head 100, and the disc tape embroidery machine head 100 is not affected when the second embroidery needle driving shaft 400 drives the flat embroidery machine head 200 to work, so that the parts of the disc tape embroidery machine head 100 are not abraded.

[0106] Further, as shown in Figure 9 , the power device three in the embodiment further comprises a first bearing 640.

[0107] The movable part of the first bearing 640 is connected with the rotating hook driving shaft, and the fixed part of the first bearing 640 is connected with the first shell wall of the rotating hook assembly 500. The first bearing 640 supports the rotating hook driving shaft and allows the first bearing 640 to rotate. The first bearing 640 is installed on the rotating hook assembly 500, so that the installation position of the rotating hook driving shaft relative to the rotating hook assembly 500 is more accurate, and the connection stability of the rotating hook driving shaft and the rotating hook assembly 500 is better.

[0108] In addition, as shown in Figure 8 , the rotating hook assembly 500 is provided with a through hole 510 allowing the rotating hook driving shaft to pass through on the second shell wall, and the second shell wall is arranged opposite to the first shell wall. The diameter of the through hole 510 is greater than the diameter of the rotating hook driving shaft.

[0109] The through hole 510 allows the rotating hook driving shaft to penetrate the shell of the rotating hook assembly 500, and the relative installation position of the rotating hook driving shaft and the rotating hook assembly 500 is more suitable without affecting the normal work of the rotating hook assembly 500.

[0110] Further, as shown in Figure 9 , the power device three in the embodiment further comprises a second bearing 650.

[0111] The movable part of the second bearing 650 is connected with the rotating hook driving shaft, and the fixed part of the second bearing 650 is connected with the bearing support frame 660. One or two or more second bearings 650 can be arranged according to actual use requirements in the embodiment, and the second bearing 650 can be arranged between two adjacent rotating hook assemblies 500. The second bearing 650 is mainly used to support the rotating hook driving shaft, so that the second bearing 650 can rotate more stably and smoothly.

[0112] Further, as shown in Figure 10 The power device three of the embodiment further comprises a pulley mounting frame 670, a pulley mounting bearing one, a pulley mounting bearing two and a rotating shaft.

[0113] The pulley mounting frame 670 is provided with a first vertical support plate and a second vertical support plate arranged oppositely. The pulley mounting frame 670 further comprises a support top plate connected with the top of the first vertical support plate and the second vertical support plate, and the support top plate is connected and fixed with the embroidery machine rack.

[0114] The fixed part of the pulley mounting bearing one is connected with the first vertical support plate.

[0115] The fixed part of the pulley mounting bearing two is connected with the second vertical support plate.

[0116] The movable part of the pulley mounting bearing one is connected with the axial first end of the rotating shaft, the movable part of the pulley mounting bearing two is connected with the axial second end of the rotating shaft, the middle part of the rotating shaft is connected and fixed with the inner ring part of the second pulley 620, and the axial first end or the axial second end of the rotating shaft is connected with the output shaft of the pulley driving motor.

[0117] The pulley mounting frame 670 is used to support the second pulley 620, so as to avoid that the whole weight of the second pulley 620 directly acts on the output shaft of the pulley driving motor, thereby making the overall structure of the power device three more stable and reliable.

[0118] Further, the hybrid machine head structure of the embodiment further comprises a first encoder, a second encoder, a rotating hook encoder and a controller.

[0119] The first encoder is connected with the first embroidery needle driving shaft 300, and the first encoder is used to obtain a first rotation angle value corresponding to the rotation position of the first embroidery needle driving shaft 300.

[0120] The first encoder is a prior art, and is fixedly connected with the first embroidery needle driving shaft 300. No matter the first embroidery needle driving shaft 300 rotates to which position clockwise or counterclockwise, a corresponding first rotation angle value can be obtained through the first encoder. For example, when the first embroidery needle driving shaft 300 rotates to position D1 clockwise (assuming that a base point is arranged on the first embroidery needle driving shaft 300, and the base point is located directly above), a corresponding first rotation angle value d1 (assuming 0 degrees) can be obtained through the first encoder; when the first embroidery needle driving shaft 300 rotates to position D2 clockwise (assuming that the base point is located on the right side), a corresponding first rotation angle value d2 (assuming 90 degrees) can be obtained through the first encoder; when the first embroidery needle driving shaft 300 rotates to position D3 clockwise (assuming that the base point is located directly below), a corresponding first rotation angle value d3 (assuming 180 degrees) can be obtained through the first encoder.

[0121] And since the mounting position of the first encoder and the first embroidery needle driving shaft 300 is fixed, even if another first encoder is replaced, as long as the first embroidery needle driving shaft 300 rotates to position D1 clockwise (i.e. the base point is located directly above), the first rotation angle value d1 obtained is still 0 degrees; the first embroidery needle driving shaft 300 rotates to position D2 clockwise (i.e. the base point is located on the right side), the first rotation angle value d2 obtained is still 90 degrees; the first embroidery needle driving shaft 300 rotates to position D3 clockwise (i.e. the base point is located directly below), the first rotation angle value d3 obtained is still 180 degrees.

[0122] In summary, the first embroidery needle driving shaft 300 rotates to any position, a corresponding first rotation angle value of the position can be obtained through the first encoder, and as long as the first embroidery needle driving shaft 300 rotates to the same position, the first rotation angle value obtained by the first encoder is the same. The first encoder is electrically connected with the controller, and the first rotation angle value obtained by the controller through the first encoder can determine what position the first embroidery needle driving shaft 300 rotates to.

[0123] The second encoder is connected with the second embroidery needle driving shaft 400, and is used for obtaining a second rotation angle value corresponding to the rotation position of the second embroidery needle driving shaft 400.

[0124] Similarly, the second encoder itself is also prior art, and the second encoder is fixedly connected with the second embroidery needle driving shaft 400. No matter where the second embroidery needle driving shaft 400 rotates clockwise or counterclockwise, a corresponding second rotation angle value can be obtained through the second encoder. For example, when the second embroidery needle driving shaft 400 rotates clockwise to position F1 (assuming that a base point is arranged on the second embroidery needle driving shaft 400, and the base point is located on the left side), a corresponding second rotation angle value f1 (assuming 0 degrees) can be obtained through the second encoder; when the second embroidery needle driving shaft 400 rotates clockwise to position F2 (assuming that the base point is located directly above), a corresponding second rotation angle value f2 (assuming 90 degrees) can be obtained through the second encoder; when the second embroidery needle driving shaft 400 rotates clockwise to position F3 (assuming that the base point is located on the right side), a corresponding second rotation angle value f3 (assuming 180 degrees) can be obtained through the second encoder.

[0125] And since the mounting position of the second encoder and the second embroidery needle driving shaft 400 is fixed, even if another second encoder is replaced, as long as the second embroidery needle driving shaft 400 rotates clockwise to position F1 (i.e., the base point is located on the left side), the obtained second rotation angle value f1 is still 0 degrees; the second embroidery needle driving shaft 400 rotates clockwise to position F2 (i.e., the base point is located directly above), the obtained second rotation angle value f2 is still 90 degrees; the second embroidery needle driving shaft 400 rotates clockwise to position F3 (i.e., the base point is located on the right side), the obtained second rotation angle value f3 is still 180 degrees.

[0126] In summary, the second embroidery needle driving shaft 400 rotates to any position, and a second rotation angle value corresponding to the position can be obtained through the second encoder, and as long as the second embroidery needle driving shaft 400 rotates to the same position, the second rotation angle value obtained by the second encoder is the same. The second encoder is electrically connected with the controller, and the second rotation angle value obtained by the controller through the second encoder can determine what position the second embroidery needle driving shaft 400 rotates to.

[0127] The rotating hook encoder is connected with the rotating hook driving shaft, and the rotating hook encoder is used to obtain a rotation angle value corresponding to a rotating position of the rotating hook driving shaft.

[0128] Similarly, the rotating hook encoder itself is also prior art, and the rotating hook encoder is fixedly connected with the rotating hook driving shaft. No matter where the rotating hook driving shaft rotates clockwise or counterclockwise, a corresponding rotation angle value can be obtained through the rotating hook encoder. For example, when the rotating hook driving shaft rotates clockwise to position S1 (assuming that a base point is arranged on the rotating hook driving shaft, and the base point is located directly above), a corresponding rotation angle value s1 (assuming 10 degrees) can be obtained through the rotating hook encoder; when the rotating hook driving shaft rotates clockwise to position S2 (assuming that the base point is located on the right side), a corresponding rotation angle value s2 (assuming 100 degrees) can be obtained through the rotating hook encoder; when the rotating hook driving shaft rotates clockwise to position S3 (assuming that the base point is located directly below), a corresponding rotation angle value s3 (assuming 190 degrees) can be obtained through the rotating hook encoder.

[0129] Since the installation position of the rotating hook encoder and the rotating hook driving shaft is fixed, even if another rotating hook encoder is replaced, as long as the rotating hook driving shaft rotates clockwise to position S1 (i.e., the base point is located directly above), the obtained rotation angle value s1 is still 10 degrees; as long as the rotating hook driving shaft rotates clockwise to position S2 (i.e., the base point is located on the right side), the obtained rotation angle value s2 is still 100 degrees; as long as the rotating hook driving shaft rotates clockwise to position S3 (i.e., the base point is located directly below), the obtained rotation angle value s3 is still 190 degrees.

[0130] In summary, the rotating hook driving shaft rotates to any position, and a rotation angle value corresponding to the position can be obtained through the rotating hook encoder, and as long as the rotating hook driving shaft rotates to the same position, the rotation angle value obtained by the rotating hook encoder is the same. The pulley driving motor is electrically connected with the controller, and the running state of the pulley driving motor (such as starting the pulley driving motor, stopping the pulley driving motor, or adjusting the rotating speed of the pulley driving motor) can be controlled through the controller.

[0131] The controller is electrically connected with the first encoder, the second encoder, the rotating hook encoder, the first driving motor, the second driving motor, and the pulley driving motor.

[0132] The first embroidery needle driving shaft 300 in the embodiment is connected with the needle bar driving assembly of the disc band embroidery machine head 100, and the second embroidery needle driving shaft 400 is connected with the needle bar driving assembly of the flat embroidery machine head 200. The needle bar driving assembly of the embodiment can directly adopt prior art. The rotation of the first embroidery needle driving shaft 300 or the second embroidery needle driving shaft 400 can drive the needle bar driving assembly to act, and the action of the needle bar driving assembly can drive the needle bar of the disc band embroidery machine head 100 or the flat embroidery machine head 200 to move up and down. The needle bar moves up and down once for each rotation of the first embroidery needle driving shaft 300 or the second embroidery needle driving shaft 400.

[0133] As shown in Figure 8 The rotating hook assembly 500 in this embodiment includes a first driving wheel 520, a second driving wheel 530 and a rotating hook body 540. The first driving wheel 520 is connected with the rotating hook driving shaft, and the central axis direction of the first driving wheel 520 is the same as the length direction of the rotating hook driving shaft. The central axis direction of the second driving wheel 530 is perpendicular to the central axis direction of the first driving wheel 520, and the second driving wheel 530 is engagedly connected with the first driving wheel 520. The rotating hook body 540 is connected with the second driving wheel 530. When the power device drives the rotating hook driving shaft to rotate, the rotating hook driving shaft drives the first driving wheel 520 to rotate synchronously, the first driving wheel 520 drives the second driving wheel 530 to rotate when rotating, and the second driving wheel 530 drives the rotating hook body 540 to rotate when rotating.

[0134] Taking the first embroidery needle driving shaft 300 as an example, it is assumed that when the first rotation angle value of the first embroidery needle driving shaft 300 is in the range of 231 degrees to 109 degrees, the embroidery needle is above the workbench, and in the process that the first rotation angle value changes from 231 degrees to 360 degrees (i.e. 0 degrees) and then to 109 degrees, the needle rod first drives the embroidery needle to move upward and then drives the embroidery needle to move downward. It is assumed that when the first rotation angle value of the first embroidery needle driving shaft 300 is in the range of 110 degrees to 230 degrees, the embroidery needle is below the workbench, and in the process that the first rotation angle value changes from 110 degrees to 230 degrees, the needle rod first drives the embroidery needle to move downward and then drives the embroidery needle to move upward.

[0135] Similarly, when the second rotation angle value of the second embroidery needle driving shaft 400 is in the range of 231 degrees to 109 degrees, the embroidery needle is above the workbench, and in the process that the second rotation angle value changes from 231 degrees to 360 degrees (i.e. 0 degrees) and then to 109 degrees, the needle rod first drives the embroidery needle to move upward and then drives the embroidery needle to move downward. It is assumed that when the second rotation angle value of the second embroidery needle driving shaft 400 is in the range of 110 degrees to 230 degrees, the embroidery needle is below the workbench, and in the process that the second rotation angle value changes from 110 degrees to 230 degrees, the needle rod first drives the embroidery needle to move downward and then drives the embroidery needle to move upward.

[0136] Assuming that when the rotation angle value of the embroidery needle driving shaft is 200 degrees and the rotation angle value of the rotating hook driving shaft is also 200 degrees (the rotation angle value of the rotating hook driving shaft can be 190 degrees or other angle values), the embroidery needle and the rotating hook body 540 complete the needle lowering and thread taking, which is equivalent to the needle lowering angle of the embroidery needle driving shaft being 200 degrees and the thread taking angle of the rotating hook driving shaft being 200 degrees (if the rotation angle value of the rotating hook driving shaft is 190 degrees, then the thread taking angle of the rotating hook driving shaft is 190 degrees). In this case, the needle lowering angle of the embroidery needle driving shaft is always 200 degrees, because in the prior art, the rotating hook driving shaft rotates synchronously with the embroidery needle driving shaft through the synchronous belt (the embroidery needle driving shaft rotates by how many degrees, and the rotating hook driving shaft also needs to rotate by how many degrees), so when the thread taking angle of the rotating hook driving shaft is initially 200 degrees, it will always be 200 degrees subsequently; if it is initially 190 degrees, it will always be 190 degrees subsequently. That is, in the existing computer embroidery machine hybrid head structure, once the thread taking angle of the rotating hook driving shaft is determined, it cannot be adjusted subsequently.

[0137] If the thread taking angle of the rotating hook driving shaft cannot be adjusted, then if the size of the thread changes subsequently, for example, the size of the thread becomes larger, it is easy to cause thread breakage.

[0138] And in this embodiment, the rotating hook driving shaft is driven by the power device three, rather than synchronously rotating with the embroidery needle driving shaft through the synchronous belt. Therefore, when the size of the thread changes, the thread taking angle of the rotating hook driving shaft can be adjusted.

[0139] For example, when the size of the thread is in the first size range, the needle lowering angle of the embroidery needle driving shaft (the first embroidery needle driving shaft 300 or the second embroidery needle driving shaft 400) is 200 degrees, the thread taking angle of the rotating hook driving shaft is 200 degrees, and the rotating hook driving shaft rotates synchronously with the embroidery needle driving shaft (that is, the embroidery needle driving shaft rotates by 1 degree to become 201 degrees, and the rotating hook driving shaft also rotates by 1 degree to become 201 degrees). When the embroidery needle driving shaft rotates to a rotation angle value of 200 degrees each time, the rotating hook driving shaft also rotates to a rotation angle value of 200 degrees synchronously, at which time the embroidery needle and the rotating hook body 540 complete the needle lowering and thread taking.

[0140] Subsequently, when the size of the thread becomes larger and enters the second size range, the needle lowering angle of the embroidery needle driving shaft is still 200 degrees, the thread taking angle of the rotating hook driving shaft can be adjusted to 195 degrees, and the rotating hook driving shaft rotates synchronously with the embroidery needle driving shaft (that is, the embroidery needle driving shaft rotates by 1 degree to become 201 degrees, and the rotating hook driving shaft also rotates by 1 degree to become 196 degrees). When the embroidery needle driving shaft rotates to a rotation angle value of 200 degrees each time, the rotating hook driving shaft also rotates to a rotation angle value of 195 degrees synchronously, at which time the embroidery needle and the rotating hook body 540 complete the needle lowering and thread taking.

[0141] In summary, the mixed machine head structure of the computerized embroidery machine of the embodiment can adaptively adjust the thread taking angle of the rotating shuttle driving shaft according to the size of the thread, thereby avoiding thread breakage caused by the change of the thread size.

[0142] The above merely illustrates the exemplary embodiments of the present application, and cannot limit the scope of the present application.
