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 rotating shuttle driving shaft structure. 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 on the computerized embroidery machine. Therefore, the existing computerized embroidery machine usually sets up both a flat embroidery head and a disc ribbon embroidery head (disc ribbon embroidery is a combination of rope embroidery and ribbon embroidery). The existing computerized embroidery machine drives the flat embroidery head and the disc ribbon embroidery head through an embroidery needle driving shaft.

[0003] Usually, a rotating shuttle assembly is provided below each head, and the rotating shuttle assembly is driven by a rotating shuttle driving shaft. In the prior art, the rotating shuttle driving shaft and the embroidery needle driving shaft are connected through a synchronous belt. The working principle is that the motor drives the embroidery needle driving shaft to rotate, thereby enabling the head to work, and the embroidery needle driving shaft drives the rotating shuttle driving shaft to rotate synchronously through the synchronous belt, thereby enabling the rotating shuttle assembly to work synchronously.

[0004] That is, the existing rotating shuttle driving shaft structure requires the rotating shuttle driving shaft to rotate synchronously with the embroidery needle driving shaft, thereby enabling the rotating shuttle assembly to work synchronously with the head. However, some embroidery schemes (such as hole carving embroidery) only require the embroidery needle driving shaft to drive the head to work, and the rotating shuttle assembly below can actually not work. At this time, if the rotating shuttle assembly works synchronously with the head, it will cause unnecessary wear and tear to the rotating shuttle assembly, thereby reducing the service life of the rotating shuttle assembly. SUMMARY

[0043] Embodiment 1:

[0044] A rotating hook driving shaft structure, comprising a rotating hook driving shaft and a power device.

[0045] The rotating hook driving shaft is connected with all rotating hook assemblies 500.

[0046] As shown in Figure 1 and Figure 2 , the rotating hook assembly 500 in the embodiment is arranged below the disc tape embroidery machine head 100 or the flat embroidery machine head 200. All disc tape embroidery machine heads 100 are driven by a first embroidery needle driving shaft 300, and all flat embroidery machine heads 200 are driven by a second embroidery needle driving shaft 400. Whether the first embroidery needle driving shaft 300 or the second embroidery needle driving shaft 400 is not connected with the rotating hook driving shaft through a synchronous belt.

[0047] As shown in Figure 4 and Figure 5 , the power device of the embodiment comprises a first pulley 610, a pulley driving motor, a second pulley 620, and a power belt 630.

[0048] The inner ring part of the first pulley 610 is connected with the rotating hook driving shaft. According to actual use requirements, one or two or more first pulleys 610 can be arranged on the rotating hook driving shaft.

[0049] The inner ring part of the second pulley 620 is connected with the output shaft of the pulley driving motor. There are several first pulleys 610, and there are corresponding several second pulleys 620. There are several second pulleys 620, and there are corresponding several pulley driving motors. The pulley driving motor is fixedly connected with the embroidery machine rack through the motor mounting frame. The pulley driving motor is electrically connected with the controller, and the running state of the pulley driving motor can be controlled through the controller (for example, the pulley driving motor is controlled to start, or the pulley driving motor is controlled to stop, or the rotating speed of the pulley driving motor is adjusted, etc.).

[0050] The power belt 630 connects the outer ring part of the first pulley 610 and the outer ring part of the second pulley 620. The power belt 630, the first pulley 610, and the second pulley 620 provide power for the rotation of the rotating hook driving shaft in cooperation with the pulley driving motor.

[0051] Working principle: the pulley driving motor drives the second pulley 620 to rotate, the second pulley 620 drives the power belt 630 to rotate, the power belt 630 drives the first pulley 610 to rotate, and the first pulley 610 drives the rotating hook driving shaft to rotate. When there are multiple pulley driving motors, only the working frequencies of the multiple pulley driving motors need to be the same.

[0052] The rotating hook driving shaft structure of the embodiment is driven by the power device instead of rotating synchronously 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 drives the rotating hook driving shaft to rotate; when the rotating hook driving shaft does not need to rotate, the power device stops 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, avoiding unnecessary wear of the rotating hook assembly 500, and thus prolonging the service life of the rotating hook assembly 500. In addition, the power device in the embodiment can provide sufficient driving force to the rotating hook driving shaft, so that the rotating hook driving shaft can stably and smoothly rotate.

[0053] Further, as shown in Figure 4 The power device in the embodiment further includes a first bearing 640.

[0054] 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.

[0055] In addition, as shown in Figure 3As shown, the shuttle assembly 500 has a through hole 510 on the second housing wall to allow the shuttle drive shaft to pass through, and the second housing wall is disposed opposite to the first housing wall. The diameter of the through hole 510 is larger than the diameter of the shuttle drive shaft.

[0056] The through hole 510 allows the shuttle drive shaft to pass through the housing of the shuttle assembly 500, making the relative installation position of the shuttle drive shaft and the shuttle assembly 500 more suitable without affecting the normal operation of the shuttle assembly 500.

[0057] Furthermore, such as Figure 4 As shown, the power unit in this embodiment also includes a second bearing 650.

[0058] The movable part of the second bearing 650 is connected to the shuttle drive shaft, and the fixed part of the second bearing 650 is connected to the bearing support frame 660. In this embodiment, one, two, or more second bearings 650 can be provided according to actual usage requirements, and the second bearings 650 can be positioned between two adjacent shuttle assemblies 500. The second bearing 650 mainly serves to support the shuttle drive shaft, enabling it to rotate more stably and smoothly.

[0059] Furthermore, such as Figure 5 As shown, the power unit in this embodiment also includes: a pulley mounting bracket 670, a pulley mounting bearing one, a pulley mounting bearing two, and a rotating shaft.

[0060] The pulley mounting bracket 670 is provided with a first vertical support plate and a second vertical support plate arranged opposite to each other. The pulley mounting bracket 670 also includes a support top plate connected and fixed to the top of the first vertical support plate and the second vertical support plate.

[0061] The fixing part of the pulley mounting bearing is connected to the first vertical support plate.

[0062] The fixing part of the pulley mounting bearing is connected to the second vertical support plate.

[0063] The first axial end of the rotating shaft is connected to the movable part of the first belt pulley mounting bearing, the second axial end of the rotating shaft is connected to the movable part of the second belt pulley mounting bearing, the middle part of the rotating shaft is connected and fixed to the inner ring of the second belt pulley 620, and the first axial end or the second axial end of the rotating shaft is connected to the output shaft of the belt pulley drive motor.

[0064] The pulley mounting bracket 670 is used to support the second pulley 620, so as to prevent the entire weight of the second pulley 620 from acting directly on the output shaft of the pulley drive motor, thereby making the overall structure of the power unit more stable and reliable.

[0065] Furthermore, the rotary shuttle drive shaft structure also includes a rotary shuttle encoder.

[0066] The rotating hook encoder is connected with the rotating hook driving shaft, and is used to obtain a rotation angle value corresponding to a rotating position of the rotating hook driving shaft.

[0067] The rotating hook encoder is a prior art, and is fixedly connected with the rotating hook driving shaft. No matter the rotating hook driving shaft rotates clockwise or counterclockwise to which position, 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.

[0068] 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.

[0069] 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 belt driving motor is electrically connected with the controller, and the running state of the belt driving motor can be controlled through the controller (for example, the belt driving motor is controlled to start, or the belt driving motor is controlled to stop, or the rotating speed of the belt driving motor is adjusted, etc.).

[0070] Further, as shown in Figure 3 the rotating hook assembly 500 in the embodiment includes a first driving wheel 520, a second driving wheel 530, and a rotating hook body 540.

[0071] 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 arranged perpendicularly to the central axis direction of the first driving wheel 520, and the second driving wheel 530 is meshingly connected with the first driving wheel 520. The rotating hook body 540 is connected with the second driving wheel 530.

[0072] 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. When the first driving wheel 520 rotates, the second driving wheel 530 is driven to rotate. When the second driving wheel 530 rotates, the rotating hook body 540 is driven to rotate.

[0073] The above is only an exemplary embodiment of the present application, which cannot limit the scope of the present application.
