[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] Please see Figures 1 to 7 The present invention discloses a thread-fastening fork assembly for a double-needle computerized embroidery machine, comprising a thread-fastening mounting plate 1, a thread-fastening driving mechanism 2, a thread-fastening guiding mechanism 3, and a thread-fastening mechanism 4. The thread-fastening mounting plate 1 is fixedly connected to the shuttle box body 5. Specifically, the thread-fastening mounting plate 1 is fixedly connected to the crossbeam 51 of the shuttle box body 5.

[0036] The wire-fastening drive mechanism 2 and the wire-fastening guide mechanism 3 are fixedly connected to the wire-fastening mounting plate 1. The wire-fastening mechanism 4 is also connected to the wire-fastening drive mechanism 2 and the wire-fastening guide mechanism 3, so that the wire-fastening fork assembly is installed on the crossbeam 51 of the shuttle box 5 through the wire-fastening mounting plate 1.

[0037] Specifically, in this application, the upper fulcrum at the bottom of the thread-fastening mechanism 4 is connected to the thread-fastening drive mechanism 2, and the lower fulcrum at the bottom of the thread-fastening mechanism 4 is connected to the thread-fastening guide mechanism 3. Thus, the thread-fastening mechanism 4 is driven by the thread-fastening drive mechanism 2 to swing back and forth around the lower fulcrum, so that the thread-fastening mechanism 4 completes the thread-fastening and thread-loosening actions, thereby enabling the thread-fastening fork assembly to cooperate with the thread-cutting mechanism set in the shuttle box 5 to complete the thread cutting.

[0038] Since the thread-fastening mechanism 4 in this application is provided with two symmetrically arranged thread-fastening forks 41, when the thread-fastening drive mechanism 2 drives the thread-fastening mechanism 4 to swing around the lower fulcrum, the thread-fastening mechanism 4 can simultaneously fasten and loosen the double-needle thread through the two symmetrically arranged thread-fastening forks 41, thereby reducing the space occupied by this thread-fastening fork assembly and making the structure of the double-needle computer embroidery machine more compact.

[0039] Furthermore, in this application, during the process of the thread-fastening drive mechanism 2 driving the thread-fastening mechanism 4 to swing around the lower fulcrum, the thread-fastening guide mechanism 3 can guide and limit the swing of the thread-fastening mechanism 4 around the lower fulcrum, making the swing of the thread-fastening mechanism 4 around the lower fulcrum more stable. That is, the thread-fastening and thread-releasing actions of the thread-fastening mechanism 4 are more stable, thereby improving the accuracy of the thread-fastening fork assembly in fastening the surface thread, ensuring the thread-cutting effect, and thus improving the embroidery quality of the double-needle computer embroidery machine.

[0040] In this embodiment, the fastening drive mechanism 2 includes a fastening driver 21 and a drive mounting base 22. The fastening driver 21 is disposed on the drive mounting base 22, and the drive mounting base 22 is fixedly connected to the fastening mounting plate 1, thereby realizing the fixed connection between the fastening drive mechanism 2 and the fastening mounting plate 1.

[0041] The upper fulcrum at the bottom of the fastening mechanism 4 is connected to the fastening driver 21, thereby driving the fastening mechanism 4 to swing around the lower fulcrum through the fastening driver 21, so that the fastening mechanism 4 can complete the actions of fastening and loosening the wire. Specifically, in actual implementation, the fastening driver 21 can be a drive motor, a drive cylinder, a drive electromagnet, etc.

[0042] In this embodiment, the wire fastening guide mechanism 3 includes a wire fastening guide seat 31 and a first wire fastening guide plate 32. The wire fastening guide seat 31 and the first wire fastening guide plate 32 are respectively disposed on both sides of the wire fastening mechanism 4, and the lower support point at the bottom of the wire fastening mechanism 4 is connected to the wire fastening guide seat 31.

[0043] When the thread-fastening driver 21 drives the thread-fastening mechanism 4 to swing around the lower fulcrum, the thread-fastening guide seat 31 and the first thread-fastening guide plate 32 are located on both sides of the thread-fastening mechanism 4 to guide and limit the swing of the thread-fastening mechanism 4 around the lower fulcrum, making the swing of the thread-fastening mechanism 4 around the lower fulcrum more stable. That is, the thread-fastening and thread-loosening actions of the thread-fastening mechanism 4 are more stable, thereby improving the accuracy of the thread-fastening fork assembly in fastening the thread, ensuring the thread-cutting effect, and thus improving the embroidery quality of the double-needle computer embroidery machine.

[0044] In this embodiment, the wire-fastening guide mechanism 3 further includes a guide pad 33, which is disposed between the wire-fastening guide seat 31 and the first wire-fastening guide plate 32. The guide pad 33 separates the wire-fastening guide seat 31 from the first wire-fastening guide plate 32, that is, the wire-fastening guide seat 31 and the first wire-fastening guide plate 32 are spaced apart, so that the wire-fastening guide seat 31 and the first wire-fastening guide plate 32 are respectively located on both sides of the wire-fastening mechanism 4.

[0045] Meanwhile, the thread guide seat 31, the guide pad 33 and the first thread guide plate 32 form a thread guide hole 34. The thread-fastening mechanism 4 passes through the thread guide hole 34, which restricts the swing stroke of the thread-fastening mechanism 4. During the swing of the thread-fastening mechanism 4, it prevents the thread-fastening mechanism 4 from shifting to both sides, thereby making the swing of the thread-fastening mechanism 4 around the lower fulcrum more stable, improving the accuracy of the thread-fastening fork assembly in fastening the thread, thus ensuring the thread-cutting effect and improving the embroidery quality of the double-needle computer embroidery machine.

[0046] In this application, the wire-fastening guide mechanism 3 also includes a guide connector, which connects the wire-fastening guide seat 31, the first wire-fastening guide plate 32 and the guide pad 33 to the wire-fastening mounting plate 1, thereby realizing the connection between the wire-fastening guide mechanism 3 and the wire-fastening mounting plate 1.

[0047] Specifically, in this embodiment, the wire-fastening guide seat 31 includes a guide seat body 311, a second wire-fastening guide plate 312, and a connecting plate 313. The second wire-fastening guide plate 312 is disposed on the top of the guide seat body 311 and extends in a direction away from the guide seat body 311. The connecting plate 313 is disposed on the bottom of the guide seat body 311 and extends in a direction away from the guide seat body 311. The extension directions of the second wire-fastening guide plate 312 and the connecting plate 313 are consistent.

[0048] As mentioned in the previous embodiment: the wire fastening guide seat 31 and the first wire fastening guide plate 32 are located on both sides of the wire fastening mechanism 4, the guide pad 33 is located between the wire fastening guide seat 31 and the first wire fastening guide plate 32, and the lower support point at the bottom of the wire fastening mechanism 4 is connected to the wire fastening guide seat 31.

[0049] Specifically, the second wire-fastening guide plate 312 and the first wire-fastening guide plate 32 are located on both sides of the wire-fastening mechanism 4, and the guide pad 33 is located between the second wire-fastening guide plate 312 and the first wire-fastening guide plate 32, so that the second wire-fastening guide plate 312, the guide pad 33 and the first wire-fastening guide plate 32 surround to form a wire-fastening guide hole 34. The lower fulcrum at the bottom of the wire-fastening mechanism 4 is connected to the connecting plate 313, so that the wire-fastening mechanism 4 passes through the wire-fastening guide hole 34, thereby realizing the guidance and limiting of the wire-fastening mechanism 4.

[0050] In this embodiment, the wire-fastening guide seat 31, the first wire-fastening guide plate 32 and the guide pad block 33 are all provided with through connection holes 3111. Specifically, the connection hole 3111 of the wire-fastening guide seat 31 is provided on the guide seat body 311.

[0051] The guide connector includes a connecting rod 35. One end of the connecting rod 35 passes through the connecting holes 3111 on the first wire-fastening guide plate 32, the guide pad 33, and the guide seat body 311 in sequence, and is then fixedly connected to the wire-fastening mounting plate 1. This connects the first wire-fastening guide plate 32, the guide pad 33, and the wire-fastening guide seat 31 to the wire-fastening mounting plate 1, thereby realizing the connection between the wire-fastening guide mechanism 3 and the wire-fastening mounting plate 1.

[0052] Furthermore, in this embodiment, the wire-fastening guide seat 31, the first wire-fastening guide plate 32, and the guide pad block 33 are all provided with through adjustment holes 3112. Specifically, the adjustment hole 3112 of the wire-fastening guide seat 31 is provided on the guide seat body 311.

[0053] The guide connector also includes an adjusting rod 36. One end of the adjusting rod 36 passes through the adjusting hole 3112 on the first wire-fastening guide plate 32, the guide pad 33 and the guide seat body 311 in sequence, and is then fixedly connected to the wire-fastening mounting plate 1.

[0054] In this application, the connecting hole 3111 is provided at the end of the guide seat body 311, the first wire-fastening guide plate 32, and the guide pad 33, and the adjusting hole 3112 is provided in the middle of the guide seat body 311, the first wire-fastening guide plate 32, and the guide pad 33. When one end of the connecting rod 35 passes through the connecting hole 3111 on the first wire-fastening guide plate 32, the guide pad 33, and the guide seat body 311 in sequence, and is fixedly connected to the wire-fastening mounting plate 1, the guide seat body 311, the first wire-fastening guide plate 32, and the guide pad 33 are rotatably connected to the connecting rod 35.

[0055] When the adjusting rod 36 passes through the adjusting hole 3112 on the first wire-fastening guide plate 32, the guide pad 33, and the guide seat body 311 in sequence, and is fixedly connected to the wire-fastening mounting plate 1, the angle of rotation of the guide seat body 311, the first wire-fastening guide plate 32, and the guide pad 33 on the connecting rod 35 can be adjusted, thereby adjusting the angle of the wire-fastening guide hole 34. The initial position of the wire-fastening mechanism 4 is limited by the wire-fastening guide hole 34, which quickly meets the installation accuracy requirements of the wire-fastening mechanism 4, thereby improving the accuracy of the wire-fastening fork assembly in fastening the surface line and ensuring the wire-cutting effect.

[0056] Specifically, in this embodiment, the adjustment hole 3112 is set as an arc-shaped strip hole, and the adjustment rod 36 is set as a screw. One end of the adjustment rod 36 passes through the adjustment hole 3112 on the first wire-fastening guide plate 32, the guide pad 33 and the guide seat body 311 in sequence, and is screwed to the wire-fastening mounting plate 1.

[0057] Since one end of the connecting rod 35 passes through the connecting hole 3111 on the first wire-fastening guide plate 32, the guide pad 33, and the guide seat body 311 in sequence, the first wire-fastening guide plate 32, the guide pad 33, and the guide seat body 311 can rotate on the connecting rod 35. Therefore, when the adjusting rod 36 is loosened from the wire-fastening mounting plate 1, and the nut at the end of the adjusting rod 36 is far away from the outer side of the first wire-fastening guide plate 32, the first wire-fastening guide plate 32, the guide pad 33, and the guide seat body 311 can rotate around the connecting rod 35, thereby adjusting the angle of the wire-fastening guide hole 34.

[0058] After the angle of the wire guide hole 34 is adjusted, the adjusting rod 36 is screwed onto the wire mounting plate 1, so that the nut at the end of the adjusting rod 36 abuts against the outer side of the first wire guide plate 32. This allows the adjusting rod 36 to fix the first wire guide plate 32, the guide pad 33, and the guide seat body 311 to the wire mounting plate 1, thereby maintaining the wire guide hole 34 at the adjusted angle.

[0059] In this embodiment, the fastening mechanism 4 further includes two fastening bodies 42, which are symmetrically arranged. Two fastening forks 41 are respectively arranged on the top of the two fastening bodies 42, and the bottom of the two fastening bodies 42 are rotatably connected to the fastening guide mechanism 3.

[0060] Specifically, the bottom of the two buckle bodies 42 is rotatably connected to the connecting plate 313, which is the lower fulcrum mentioned in the above embodiment, and is the connection point where the two buckle bodies 42 and the connecting plate 313 are rotatably connected.

[0061] The fastening mechanism 4 also includes a connecting rod 43, one end of which is rotatably connected to the middle of the two fastening bodies 42, and the other end is rotatably connected to the fastening drive mechanism 2. Specifically, the other end of the connecting rod 43 is rotatably connected to the drive shaft of the fastening driver 21, which is the upper fulcrum mentioned in the above embodiment, and is the connection point where the connecting rod 43 and the drive shaft of the fastening driver 21 are rotatably connected.

[0062] Therefore, the drive shaft of the thread fastener 21 pushes the two thread fastener bodies 42 to rotate around the lower fulcrum through the connecting rod 43, which drives the two thread fastener forks 41 at the top of the two thread fastener bodies 42 to rotate synchronously, so that the two thread fastener forks 41 respectively fasten and loosen the double-needle surface thread, and then the thread fastening is completed by the thread fastener fork assembly and the thread cutting mechanism set on the shuttle box 5.

[0063] Furthermore, in this embodiment, the fastening body 42 includes a connecting portion 421 and a fastening portion 422. The connecting portion 421 extends vertically, and the fastening portion 422 is disposed at the top of the connecting portion 421 and extends horizontally. One end of the connecting rod 43 is rotatably connected to the middle of the connecting portion 421, and the other end is rotatably connected to the drive shaft of the fastening driver 21. The connection point where the connecting rod 43 is rotatably connected to the drive shaft of the fastening driver 21 forms the aforementioned upper fulcrum.

[0064] The bottom of the connecting part 421 is rotatably connected to the thread guide mechanism 3. Specifically, the bottom of the connecting part 421 is rotatably connected to the connecting plate 313 of the thread guide mechanism 3, so that the connection point where the connecting part 421 and the connecting plate 313 are rotatably connected forms the aforementioned lower fulcrum. This allows the drive shaft of the thread driver 21 to push the connecting part 421 and the thread-fastening part 422 to rotate around the lower fulcrum via the connecting rod 43, thereby driving the two thread-fastening forks 41 to rotate synchronously, so that the two thread-fastening forks 41 respectively fasten and loosen the double-needle surface thread.
