[0070] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation manners.

[0071] Embodiment 1: As Figure 2 and Figure 3As shown in the figure, an embroidery frame driving mechanism includes an X-direction driving component 2, a Y-direction rail body 3, an X-direction connecting member 4, an X-direction rail body 5, a limit connecting frame 6, and a Y-direction driving component 7. In the embodiment of the present application, the X direction is the short side direction of the embroidery frame 1, and the Y direction is the long side direction of the embroidery frame 1.

[0072] As Figure 4 and Figures 6 to 8 shown in the figure, the X-direction driving component 2 includes an X limit guiding member 2-1, an X driving motor, an X main pulley 2-2, an X driven pulley 2-3, an X synchronous belt, an X guide rail 2-4, an X mounting bracket 2-5, an X sliding seat 2-6, and an X pressing plate 2-7. The X main pulley 2-2 is connected to the output shaft of the X driving motor. Multiple X-direction driving components 2 can share one X driving motor, that is, the output shaft of one X driving motor can drive all the X main pulleys 2-2 to rotate synchronously. The X synchronous belt connects the X main pulley 2-2 and the X driven pulley 2-3. When the X main pulley 2-2 rotates, it can drive the annular X synchronous belt to rotate synchronously.

[0073] The first end of the X guide rail 2-4 is connected to the wheel frame of the X main pulley 2-2, and the second end is connected to the wheel frame of the X driven pulley 2-3. The X guide rail 2-4 includes a guide rail housing frame connected to the wheel frames of the X main pulley 2-2 and the X driven pulley 2-3, a guide rail body connected to the bottom of the guide rail housing frame, and a guide rail cavity opened between the guide rail housing frame and the guide rail body. The guide rail cavity allows the upper belt body part of the X synchronous belt to pass through. The X mounting bracket 2-5 is connected to the guide rail housing frame of the X guide rail 2-4 and is used to connect to the frame of the embroidery machine, so that the X-direction driving component 2 can be fixed on the frame.

[0074] The X sliding seat 2-6 is slidably connected to the guide rail body of the X guide rail 2-4 and can move back and forth in the X direction relative to the X guide rail 2-4. The X pressing plate 2-7 is connected to the bottom of the X sliding seat 2-6, and an X belt body groove 2-7a allowing the lower belt body part of the X synchronous belt to pass through and cooperating with the X sliding seat 2-6 to clamp the X synchronous belt is opened at the top of the X pressing plate 2-7. The X sliding seat 2-6 and the X pressing plate 2-7 cooperate to clamp and fix the X synchronous belt. When the X synchronous belt rotates back and forth, it can drive the X sliding seat 2-6 and the X pressing plate 2-7 to move back and forth synchronously in the X direction. The bottom of the X sliding seat 2-6 is provided with anti-slip stripes to improve the clamping effect with the X synchronous belt. In addition, the X pressing plate 2-7, the X synchronous belt, and the X sliding seat 2-6 can also be connected by screws to improve the connection stability of the three.

[0075] The bottom of the X pressing plate 2-7 is connected to the X limit guiding member 2-1. As Figure 23As shown, the X-positioning guide member 2-1 includes four X-guide wheels 2-1a assembled and connected to the positioning guide groove 3-3, an X-wheel plate 2-1b connected to the axles of the X-guide wheels 2-1a, and an X-wheel plate support frame 2-1c connected to the X-wheel plate 2-1b and used to connect to the X-pressure plate 2-7. The X-wheel plate support frame 2-1c can be a support plate similar to a T shape. The top of the T-shaped support plate is connected to the X-pressure plate 2-7, and the bottom of the T-shaped support plate is connected to the X-wheel plate 2-1b. Among them, the specific dimensions of the X-wheel plate support frame 2-1c can be selected according to actual usage requirements to adapt to the actual distance between the X-pressure plate 2-7 and the X-wheel plate 2-1b.

[0076] The working principle of the X-direction driving assembly 2 is as follows: When the X driving motor rotates forward, it drives the X main pulley 2-2 to rotate forward. The forward rotation of the X main pulley 2-2 drives the X synchronous belt to rotate forward. During the forward rotation of the X synchronous belt, it drives the X sliding seat 2-6, the X-pressure plate 2-7, and the X-positioning guide member 2-1 to move forward in the X direction. During the movement, the X sliding seat 2-6 is guided by the X guide rail 2-4. When the X driving motor rotates in reverse, it drives the X main pulley 2-2 to rotate in reverse. The reverse rotation of the X main pulley 2-2 drives the X synchronous belt to rotate in reverse. During the reverse rotation of the X synchronous belt, it drives the X sliding seat 2-6, the X-pressure plate 2-7, and the X-positioning guide member 2-1 to move backward in the X direction.

[0077] As Figure 16 shown, the Y-direction rail body 3 is provided with a positioning guide groove 3-3 that is connected in the X direction and slidably connected in the Y direction to the X-positioning guide member 2-1. When the X-positioning guide member 2-1 drives the X-guide wheels 2-1a to move back and forth in the X direction, the X-guide wheels 2-1a can drive the Y-direction rail body 3 to move back and forth synchronously in the X direction.

[0078] The X-direction connecting member 4 connects the long side of the Y-direction rail body 3 and the embroidery frame 1. As Figure 21 and Figure 22 shown, a first connecting plate 3-1 is provided on the Y-direction side of the Y-direction rail body 3, and a first limiting protrusion strip 3-2 is provided at the bottom of the first connecting plate 3-1. The X-direction connecting member 4 includes a connecting block, and the connecting block is provided with a connecting block card slot that is assembled and connected to the first limiting protrusion strip 3-2. The connecting block card slot divides the connecting block into a first connecting portion and a second connecting portion. The first connecting portion is placed at the bottom of the first connecting plate 3-1 and is fixedly connected to the first connecting plate 3-1 by screws. The second connecting portion is placed at the bottom of the embroidery frame 1 and is fixedly connected to the embroidery frame 1 by screws. The setting of the connecting block card slot and the first limiting protrusion strip 3-2 makes the connection structure between the Y-direction rail body 3 and the X-direction connecting member 4 stable and reliable, so that the connection structure between the Y-direction rail body 3 and the embroidery frame 1 is stable and reliable enough. Furthermore, when the Y-direction rail body 3 moves back and forth in the X direction, it can effectively drive the embroidery frame 1 to move back and forth.

[0079] As shown Figure 5 in the figure, the X-direction rail body 5 is vertically arranged with the Y-direction rail body 3, and the end of the Y-direction rail body 3 is only in contact connection with the X-direction rail body 5.

[0080] As shown Figure 10 in the figure, a second connecting plate 5-1 is provided on the X-direction side of the X-direction rail body 5, and a second limiting convex strip 5-2 is provided on the top of the second connecting plate 5-1.

[0081] The first end of the limiting connection frame 6 is connected to the short side of the embroidery frame 1, the second end is slidably connected to the X-direction rail body 5 in the X direction and is in limiting connection in the Y direction. The limiting connection frame 6 includes a rectangular frame body, which is arranged between the short side of the embroidery frame 1 and the X-direction rail body 5 for realizing the connection between the embroidery frame 1 and the X-direction rail body 5. As shown Figure 11 and Figure 12 in the figure, a slider 6-1 is provided at the second end of the limiting connection frame 6. The slider 6-1 includes a slider main body and a slider connecting part. The slider connecting part is used for connecting and fixing with the rectangular frame body. The slider main body is provided with a slider groove for assembling and connecting with the second limiting convex strip 5-2. The slider groove enables the limiting connection frame 6 to slide back and forth in the X direction relative to the X-direction rail body 5 and enables the two to maintain relative limitation in the Y direction. A connecting piece 6-2 for connecting with the short side of the embroidery frame 1 is provided at the first end of the limiting connection frame 6. The connecting piece 6-2 includes a connecting piece main body and a connecting piece connecting part. The connecting piece main body is used for connecting and fixing with the embroidery frame 1, and the connecting piece connecting part is used for connecting and fixing with the rectangular frame body.

[0082] As shown Figure 9 and Figures 16 to 20 in the figure, an angle plate part in contact connection with the X-direction rail body 5 is provided at the end of the Y-direction rail body 3. The angle plate part includes a first angle plate body 8-1 and a second angle plate body 8-2.

[0083] The first angle plate body 8-1 is provided with a strip-shaped opening 8-1a. The strip-shaped opening 8-1a makes the first angle plate body 8-1 form an angle plate installation part for assembling and connecting with the limiting guide groove 3-3, and the first angle plate body 8-1 is also provided with a first angle plate supporting part 8-1b in contact connection with the second limiting convex strip 5-2. The first angle plate supporting part 8-1b includes two mutually perpendicular supporting surfaces, and the first angle plate supporting part 8-1b has a certain length in the X direction. When the first angle plate body 8-1 is installed, only need to put the angle plate installation part into the limiting guide groove 3-3, and then connect and fix the first angle plate body 8-1 with the Y-direction rail body 3 by screws. After the first angle plate body 8-1 is installed, its first angle plate supporting part 8-1b just supports on the X-direction rail body 5. On the one hand, it makes the Y-direction rail body move more smoothly along the X direction relative to the X-direction rail body 5, and on the other hand, it enables the Y-direction rail body to better follow the X-direction rail body 5 to move in the Y direction.

[0084] The second gusset body 8-2 is provided with a gusset mounting groove 8-2a for assembling and connecting with the first limiting convex strip 3-2, and the second gusset body 8-2 is provided with a second gusset supporting part 8-2b in contact connection with the second limiting convex strip 5-2. The second gusset supporting part 8-2b includes two mutually perpendicular supporting surfaces, and the second gusset supporting part 8-2b has a certain length in the X direction. When installing the second gusset body 8-2, only need to sleeved the gusset mounting groove 8-2a onto the second limiting convex strip 5-2, and then fix the second gusset body 8-2 to the Y-direction rail body 3 with screws. After the second gusset body 8-2 is installed, its second gusset supporting part 8-2b just supports on the X-direction rail body 5. On the one hand, it makes the Y-direction rail body move more smoothly along the X direction relative to the X-direction rail body 5. On the other hand, it enables the Y-direction rail body to better follow the X-direction rail body 5 to move in the Y direction.

The Y main pulley 7-2 is connected to the output shaft of the Y driving motor, and the Y driving motor drives the Y main pulley 7-2 to rotate. The Y synchronous belt connects the Y main pulley 7-2 and the Y driven pulley 7-3, and when the Y main pulley 7-2 rotates, it can drive the annular Y synchronous belt to rotate synchronously.

[0086] The first end of the Y guide rail 7-4 is connected to the wheel frame of the Y main pulley 7-2, and the second end is connected to the wheel frame of the Y driven pulley 7-3. The Y guide rail 7-4 includes a guide rail housing frame connected to the wheel frames of the Y main pulley 7-2 and the Y driven pulley 7-3, a guide rail body connected to the top of the guide rail housing frame, and a guide rail cavity formed between the guide rail housing frame and the guide rail body. The guide rail cavity allows the lower belt body part of the Y synchronous belt to pass through. The Y mounting bracket 7-5 is connected to the guide rail housing frame of the Y guide rail 7-4 and is used to connect to the frame of the embroidery machine, so that the Y-direction driving assembly 7 can be fixed on the frame.

[0087] The Y sliding seat 7-6 is slidably connected to the guide rail body of the Y guide rail 7-4 and can move back and forth in the Y direction along the Y guide rail 7-4. The Y pressing plate 7-7 is connected to the bottom of the Y sliding seat 7-6, and a Y belt body groove 7-7a allowing the upper belt body part of the Y synchronous belt to pass through and cooperating with the Y sliding seat 7-6 to clamp the Y synchronous belt is formed at the bottom of the Y pressing plate 7-7. The Y sliding seat 7-6 and the Y pressing plate 7-7 cooperate to clamp and fix the Y synchronous belt. When the Y synchronous belt rotates back and forth, it can drive the Y sliding seat 7-6 and the Y pressing plate 7-7 to move back and forth synchronously in the Y direction. Anti-slip stripes are provided on the top of the Y sliding seat 7-6 to improve the clamping effect with the Y synchronous belt. In addition, the Y pressing plate 7-7, the Y synchronous belt, and the Y sliding seat 7-6 can also be connected by screws to improve the connection stability of the three.

[0088] The top of the Y pressing plate 7-7 is connected to the Y limit guiding member 7-1. As Figure 15 shown, the Y limit guiding member 7-1 includes four Y guide wheels 7-1a assembled and connected to the limit groove 5-3, a Y wheel plate 7-1b connected to the axle of the Y guide wheel 7-1a, and a Y wheel plate support frame 7-1c connected to the Y wheel plate 7-1b and used for connecting to the Y pressing plate 7-7. The Y wheel plate support frame 7-1c can be a support bar, the bottom of the support bar is connected to the Y pressing plate 7-7, and the top is connected to the Y wheel plate 7-1b.

[0089] The working principle of the Y-direction driving assembly 7 is as follows: When the Y driving motor rotates forward, it drives the Y main pulley 7-2 to rotate forward. The forward rotation of the Y main pulley 7-2 drives the Y synchronous belt to rotate forward. During the forward rotation of the Y synchronous belt, it drives the Y sliding seat 7-6, the Y pressing plate 7-7, and the Y limit guiding member 7-1 to move leftward in the Y direction, and the Y sliding seat 7-6 is guided by the Y guide rail 7-4 during the movement. When the Y driving motor rotates in reverse, it drives the Y main pulley 7-2 to rotate in reverse. The reverse rotation of the Y main pulley 7-2 drives the Y synchronous belt to rotate in reverse. During the reverse rotation of the Y synchronous belt, it drives the Y sliding seat 7-6, the Y pressing plate 7-7, and the Y limit guiding member 7-1 to move rightward in the Y direction.

[0090] The X-direction rail body 5 is provided with a limiting groove 5-3 that is connected to the Y-direction guide wheel 7-1a in the Y-direction for limiting. When the Y-direction driving component 7 drives the Y-direction limiting guide member 7-1 to move leftward, the Y-direction guide wheel 7-1a can drive the X-direction rail body 5 to move leftward. During the movement of the X-direction rail body 5, it can push the Y-direction rail body 3 and the limiting connection frame 6 to move leftward. During the leftward movement of the Y-direction rail body 3, the overall position of the X-direction guide wheel 2-1a assembled and connected to it remains unchanged. During the leftward movement of the limiting connection frame 6, it can push the embroidery frame 1 to move leftward. When the Y-direction driving component 7 drives the Y-direction limiting guide member 7-1 to move rightward, the Y-direction guide wheel 7-1a can drive the X-direction rail body 5 to move rightward. During the movement of the X-direction rail body 5, it can pull the limiting connection frame 6 to move rightward. During the rightward movement of the limiting connection frame 6, it can pull the embroidery frame 1 to move rightward. During the rightward movement of the embroidery frame 1, it can drive the Y-direction rail body 3 to move rightward, and during the rightward movement of the Y-direction rail body 3, the overall position of the X-direction guide wheel 2-1a assembled and connected to it remains unchanged.

[0091] In this application, the embroidery frame is driven to move back and forth in the X direction through the X-direction driving component, Y-direction rail body, X-direction connecting piece, limiting connection frame, and X-direction rail body, and the embroidery frame is driven to move back and forth in the Y direction through the Y-direction driving component, X-direction rail body, limiting connection frame, and Y-direction rail body. Compared with the embroidery frame driving mechanism in the form of a threaded rod, the embroidery frame driving mechanism with the structure of this embodiment of the application has a higher transmission efficiency, so that the embroidery frame can move quickly.
