[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Please refer to the appendix. Figures 1-4 The present invention provides a multi-needle synchronous drive device for a computer embroidery machine, comprising a mounting back plate 1 and a mounting bracket 2. A plurality of machine heads 3 are evenly fixed at the front end of the mounting bracket 2. A plurality of thread spools 4 are rotatably mounted on the surface of each machine head 3. A housing 5 is fixed at the bottom end of each machine head 3. A needle 6 is installed inside the housing 5 through an elastic component. A first drive component for synchronously driving the plurality of needles 6 is also fixed at the bottom of the mounting bracket 2. The mounting bracket 2 is mounted on the front side of the mounting back plate 1 through a second drive component.

[0023] The elastic component includes several vertically arranged limiting holes 7, which are respectively opened at the bottom of several housings 5. The needles 6 all pass vertically through the limiting holes 7, and the surface of the needles 6 is in contact with the wall of the limiting holes 7. A driving block 8 is fixed to the top of each needle 6. The top of the driving block 8 is arc-shaped. A return spring 9 is vertically fixed to the bottom of each driving block 8. The return spring 9 is sleeved on the surface of the needle 6, and the bottom of the return spring 9 is fixed to the bottom of the inner wall of the housing 5. Specifically, under the limiting action of the limiting holes 7, when the driving block 8 is subjected to the squeezing driving force, it can press down the needle 6 to move down stably. When the needle 6 moves down under the force, it will compress the return spring 9, causing the return spring 9 to undergo elastic deformation and generate elastic force. Under the action of this elastic force, when the squeezing driving force on the driving block 8 disappears, it can drive the driving block 8 to move up to its original position, thereby driving the needle 6 to move up to return to its original position.

[0024] The first drive assembly includes a first end plate 10 and a second end plate 11. The top ends of the first end plate 10 and the second end plate 11 are symmetrically fixed to the bottom two sides of the mounting bracket 2. A servo motor 12 is fixed to the side end of the second end plate 11. A drive rod 13 is fixed to the output shaft of the servo motor 12. The drive rod 13 passes horizontally through the two sides of several housings 5. The surface of the drive rod 13 is rotatably connected to the side end of the housing 5 through a bearing 14. The end of the drive rod 13 is rotatably mounted on the side end of the first end plate 10. Several drive cams 15 are fixed to the surface of the drive rod 13. The several drive cams 15 correspond one-to-one with several drive blocks 8. The surface of the drive cam 15 is aligned with the corresponding drive block. The tops of the 8 parts abut against each other. Specifically, when the servo motor 12 is running, it can drive several drive cams 15 to rotate synchronously through the drive rod 13. When the protruding ends of several drive cams 15 rotate onto the drive block 8, a squeezing driving force is applied synchronously to several drive blocks 8, thereby causing several needles 6 to move down synchronously. When the protruding ends of several drive cams 15 rotate past the drive block 8, several needles 6 move up and return to their original positions under the action of the return spring 9, thus realizing the up-and-down reciprocating motion of several needles 6. That is, this device can effectively realize the function of synchronously driving multiple needles to perform multiple embroidery processing in a single operation, thereby effectively improving the single-operation embroidery efficiency of the computer embroidery machine.

[0025] The second drive assembly includes a vertically arranged electric push rod 16. The top of the electric push rod 16 is symmetrically fixed to the top of the mounting back plate 1. The bottom of the output shaft of the electric push rod 16 is fixed with a first connecting plate 17. The two sides of the mounting bracket 2 are symmetrically fixed with second connecting plates 18. The tops of the two second connecting plates 18 are respectively fixed to the bottoms of the two first connecting plates 17. Specifically, when the electric push rod 16 is running, it can drive the mounting bracket 2 to move up and down through the first connecting plates 17 and the second connecting plates 18, thereby achieving synchronous driving of the multi-needle head to move up and down, and conveniently adjusting the required working height of the multi-needle head.

[0026] It should be noted that the device is electrically connected to an external main controller and 220V AC mains power, and the main controller can be an existing technology device such as a computer for control.

[0027] The usage process of this utility model is as follows: The operator can first control the electric push rod 16 to run. When the electric push rod 16 runs, it can drive the mounting bracket 2 to move up and down through the first connecting plate 17 and the second connecting plate 18, thereby achieving synchronous driving of the multi-needle head to move up and down, and conveniently adjusting the required working height of the multi-needle head. When the multi-needle head 6 is raised to the required height, the operator can control the servo motor 12 to run. When the servo motor 12 runs, it can drive several drive cams 15 to rotate synchronously through the drive rod 13. When the protruding ends of several drive cams 15 rotate onto the drive block 8, a squeezing driving force is applied synchronously to several drive blocks 8. When the drive block 8 is squeezed... When the driving force is applied, the needle 6 can be pressed down to move stably downward. When the needle 6 moves downward under force, it will compress the return spring 9, causing the return spring 9 to undergo elastic deformation and generate elastic force. Under the action of this elastic force, when the squeezing driving force on the drive block 8 disappears, the drive block 8 can be driven to move upward to its original position, thereby driving the needle 6 to move upward to return to its original position. That is, when the protruding ends of several drive cams 15 rotate over the drive block 8, several needles 6 move upward to return to their original position under the action of the return spring 9, thus realizing the up-and-down reciprocating movement of several needles 6. In other words, this device can effectively realize the function of synchronously driving multiple needles to perform multiple embroidery processing in a single operation, thereby effectively improving the single-operation embroidery efficiency of the computer embroidery machine.

[0028] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
