[0018] The single-head embroidery machine suitable for large-format embroidery proposed in the utility model has the following beneficial effects:

[0019] (1) The active area of the wide-width embroidery frame assembly of the single-head embroidery machine is formed below the frame and on one side of the connecting column, that is, the connecting column only hinders the movement of the wide-width embroidery frame assembly in one direction, thereby increasing the active range of the wide-width embroidery frame assembly in the active area as much as possible, that is, increasing the stroke of the wide-width embroidery frame assembly, thereby increasing the embroidery area of the single-head embroidery machine, making the single-head embroidery machine suitable for large-format embroidery;

[0020] (2) When the wide-width embroidery frame assembly of the single-head embroidery machine moves horizontally in the active area, the support platform supports the wide-width embroidery frame assembly, and the projected area of the wide-width embroidery frame assembly on the support platform always exceeds half of the cross-sectional area of the wide-width embroidery frame assembly. Therefore, no matter where the wide-width embroidery frame assembly moves in the active area, the support platform always provides a large range of support for the wide-width embroidery frame assembly, thereby enhancing the stability of the wide-width embroidery frame assembly during operation and ensuring the quality of the embroidery product;

[0021] (3) The split base of this single-head embroidery machine includes a lower support base and an upper support base. The lower support base abuts against the ground, and the upper support base is arranged on the lower support base.

Detailed implementation manners

[0037] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] Please refer to Figures 1 to 8 , a single-head embroidery machine applicable to large-format embroidery according to an embodiment of the present utility model, includes a split base 1, a support platform 2 provided on the split base 1, a wide-format embroidery frame assembly 3 for fixing a wide-width fabric, a frame 4 provided above the wide-format embroidery frame assembly 3, a needle assembly 5 provided at the head end of the frame 4, and a connecting column 6 connecting the tail end of the frame 4 to the split base 1; an activity area 110 is provided on one side of the connecting column 6, and the wide-format embroidery frame assembly 3 drives the wide-width fabric to move horizontally in the activity area 110, and the needle assembly 5 moves vertically on the frame 4 to pass the surface thread through the wide-width fabric fixed by the wide-format embroidery frame assembly 3; during the process that the wide-format embroidery frame assembly 3 drives the wide-width fabric to move horizontally in the activity area 110, the support platform 2 supports the wide-format embroidery frame assembly 3, and the projected area of the wide-format embroidery frame assembly 3 on the support platform 2 exceeds half of the cross-sectional area of the wide-format embroidery frame assembly 3.

[0039] In this patent, the single-head embroidery machine includes a split base 1, a support platform 2, a wide-format embroidery frame assembly 3, a frame 4, a needle assembly 5 and a connecting column 6. Among them, the support platform 2 is provided on the split base 1, and the wide-format embroidery frame assembly 3 can move horizontally on the support platform 2.

[0040] Specifically, a frame 4 is provided above the wide-format embroidery frame assembly 3. The head end of the frame 4 is used to install the needle assembly 5, and the connecting column 6 connects the tail end of the frame 4 to the split base 1, thereby forming an activity area 110 for the wide-format embroidery frame assembly 3 to move below the frame 4 and on one side of the connecting column 6. The wide-format embroidery frame assembly 3 moves horizontally in the activity area 110.

[0041] When embroidering, the wide-width fabric is fixed on the wide-format embroidery frame assembly 3. By moving the wide-format embroidery frame assembly 3 horizontally back and forth and left and right in the activity area 110, the wide-width fabric is driven to move horizontally back and forth and left and right synchronously. The needle assembly 5 located at the head end of the frame 4 can move up and down vertically on the frame 4, so that the needle assembly 5 embroiders the wide-width fabric fixed on the wide-format embroidery frame assembly 3.

[0042] Specifically, in this embodiment, the single-head embroidery machine further includes a shuttle box assembly 9. The shuttle box assembly 9 is disposed on the support platform 2 and is located below the wide-width embroidery frame assembly 3. When embroidering, first, the needle assembly 5 moves vertically downward on the frame 4 to pass the surface thread through the wide-width fabric fixed on the wide-width embroidery frame assembly 3. The shuttle box assembly 9 is below the wide-width embroidery frame assembly 3 and cooperates with the needle assembly 5 to complete the thread locking action.

[0043] Then, the wide-width embroidery frame assembly 3 drives the wide-width fabric to move horizontally, cooperating with the vertical downward movement of the needle assembly 5 on the frame 4, so that the needle assembly 5 passes the surface thread through another position of the wide-width fabric. The shuttle box assembly 9 cooperates with the needle assembly 5 to complete the next thread locking action; repeating the above steps can embroider a preset pattern on the wide-width fabric, thereby completing the embroidery work of the large-format embroidery.

[0044] The embroidery area of the existing single-head embroidery machine is small. On the one hand, it is limited by the stroke of the embroidery frame during the embroidery process, and on the other hand, it is limited by the size of the embroidery frame, resulting in the single-head embroidery machine being unable to be applied to the embroidery work of large-format embroideries. Therefore, in this patent, the activity area 110 of the wide-width embroidery frame assembly 3 is formed below the frame 4 and on one side of the connecting column 6, that is, the connecting column 6 only hinders the movement of the wide-width embroidery frame assembly 3 in one direction, thereby maximizing the movement range of the wide-width embroidery frame assembly 3 in the activity area 110, that is, increasing the stroke of the wide-width embroidery frame assembly 3, and further increasing the embroidery area of the single-head embroidery machine, making the single-head embroidery machine applicable to large-format embroidery.

[0045] In addition, to further make this single-head embroidery machine applicable to large-format embroidery, the wide-width embroidery frame assembly 3 in this patent can adopt a large-size wide-width embroidery frame assembly 3, so that it can fix the wide-width fabric and form a large-range embroidery area on the wide-width fabric fixed on the wide-width embroidery frame assembly 3, thereby facilitating large-format embroidery of the wide-width fabric.

[0046] It can be foreseen that increasing the stroke of the wide-width embroidery frame assembly 3 and increasing the size of the wide-width embroidery frame assembly 3 will also have an adverse impact on the running stability of the wide-width embroidery frame assembly 3, thereby affecting the quality of the embroidery. Therefore, to ensure the quality of the embroidery, for the wide-width embroidery frame assembly 3 with a large stroke and a large size, the requirement for its running stability is also higher.

[0047] In this patent, during the horizontal movement of the wide-format embroidery frame assembly 3 in the active area 110, the support platform 2 supports the wide-format embroidery frame assembly 3, and the projected area of the wide-format embroidery frame assembly 3 on the support platform 2 always exceeds half of the cross-sectional area of the wide-format embroidery frame assembly 3. Thus, no matter which position the wide-format embroidery frame assembly 3 runs to in the active area 110, the support platform 2 always provides a large range of support for the wide-format embroidery frame assembly 3, thereby enhancing the stability of the wide-format embroidery frame assembly 3 during operation and ensuring the quality of the embroidered product.

[0048] Preferably, in actual implementation, the projected area of the wide-format embroidery frame assembly 3 on the support platform 2 exceeds 90% of the cross-sectional area of the wide-format embroidery frame assembly 3, thereby further enhancing the support effect of the support platform 2 on the wide-format embroidery frame assembly 3, and further enhancing the stability of the wide-format embroidery frame assembly 3 during operation and ensuring the quality of the embroidered product.

[0049] In this embodiment, the split base 1 includes a lower support seat for abutting against the ground and an upper support seat provided on the lower support seat. The support platform 2 is provided on the upper support seat, and the connecting column 6 connects the tail end of the frame 4 to the upper support seat. During the operation of the single-head embroidery machine, the vibration generated and the interference from the external environment are also important factors affecting the quality of the embroidered product.

[0050] Therefore, in this patent, the split base 1 includes a lower support seat and an upper support seat. The lower support seat abuts against the ground, and the upper support seat is provided on the lower support seat. The support platform 2 is provided on the upper support seat, and the connecting column 6 connects the tail end of the frame 4 to the upper support seat. The support platform 2 and the frame 4 are supported by the double-layer support seat, so as to better buffer the vibration generated during the operation of the single-head embroidery machine and better eliminate the interference from the external environment, thereby improving the stability of the operation of the single-head embroidery machine and ensuring the quality of the embroidered product.

[0051] Specifically, in this embodiment, the upper support seat includes a first support frame 11 and buffer feet 12 provided at the bottom of the first support frame 11. The lower support seat includes a second support frame 14 and movable feet 15 provided at the bottom of the second support frame 14. The support platform 2 is provided on the first support frame 11, the connecting column 6 connects the tail end of the frame 4 to the first support frame 11, the buffer feet 12 are fixedly connected to the second support frame 14, and the movable feet 15 can move on the ground.

[0052] In this patent, the upper support base includes a first support frame 11 and buffer feet 12, and the lower support base includes a second support frame 14 and movable feet 15. The movable feet 15 are arranged at the bottom of the second support frame 14, and the buffer feet 12 are arranged at the bottom of the first support frame 11. The movable feet 15 are in contact with the ground to support the second support frame 14, and the buffer feet 12 connect the first support frame 11 and the second support frame 14 to support the first support frame 11.

[0053] The support platform 2 is arranged on the first support frame 11, and the connecting column 6 connects the tail end of the frame 4 with the first support frame 11. Thus, through the first support frame 11 and the second support frame 14, vibrations generated during the operation of the single-head embroidery machine and interference from the external environment can be better absorbed. Through the buffer feet 12 and the movable feet 15, vibrations generated during the operation of the single-head embroidery machine and interference from the external environment can be better buffered, thereby improving the operating stability of the single-head embroidery machine and ensuring the quality of embroidered products.

[0054] In this patent, the movable feet 15 can move on the ground. Thus, in actual use, through the movable feet 15, the movement of this single-head embroidery machine can be made simpler, more convenient, time-saving and labor-saving, and thus this single-head embroidery machine can meet different usage requirements of users and enhance the practicability of this single-head embroidery machine.

[0055] Specifically, during actual implementation, an elastic buffer pad can be arranged at the bottom of the buffer feet 12. After a bolt passes through the through hole on the elastic buffer pad and is screwed into the threaded hole on the second support frame 14, the fixed connection between the buffer feet 12 and the second support frame 14 is realized. The movable feet 15 can adopt universal wheels.

[0056] In this embodiment, the upper support base further includes support wing plates 13 arranged on both sides of the first support frame 11. A plurality of support beams are arranged at the bottom of the support platform 2, and the support wing plates 13 are fixedly connected to the plurality of support beams to support the support platform 2. Since in this patent, during the horizontal movement of the wide-width embroidery frame assembly 3 in the active area 110, no matter which position the wide-width embroidery frame assembly 3 moves to, the support platform 2 always provides a large range of support for the wide-width embroidery frame assembly 3. Therefore, it can be foreseen that during actual implementation, the cross-sectional area of the support platform 2 is much larger than the cross-sectional area of the first support frame 11.

[0057] In this patent, the upper support base further includes support wing plates 13 which extend outward on both sides of the first support frame 11. A plurality of support beams are provided at the bottom of the support platform 2. By fixedly connecting the support wing plates 13 to the plurality of support beams simultaneously, the support wing plates 13 support the area of the support platform 2 that extends beyond the first support frame 11, enhancing the support effect of the upper support base on the support platform 2, thereby improving the stability of the structure of the single-head embroidery machine and ensuring the quality of the embroidered products.

[0058] In this embodiment, the frame 4 includes two cantilevers 41 arranged in parallel at intervals, and a connecting frame 42 connecting the two cantilevers 41. The connecting column 6 connects the tails of the two cantilevers 41 to the split base 1, and the needle assembly 5 is arranged at the head of the connecting frame 42. In this patent, the frame 4 includes two cantilevers 41 and a connecting frame 42. The two cantilevers 41 are arranged opposite to each other at intervals, and the connecting frame 42 is located between the two cantilevers 41. The two ends of the connecting frame 42 are respectively connected to the two cantilevers 41, so that the two cantilevers 41 are connected by the connecting frame 42, and the two cantilevers 41 and the connecting frame 42 form an integral structure, thereby enhancing the stability of the structure of the frame 4.

[0059] The needle assembly 5 is installed at the head of the connecting frame 42, so that the needle assembly 5 is located above the wide-width embroidery frame assembly 3. The connecting column 6 connects the tails of the two cantilevers 41 to the split base 1, so that the needle assembly 5 is more stable in installation on the frame 4, further ensuring the quality of the embroidered products.

[0060] In this embodiment, the single-head embroidery machine further includes an X-axis drive assembly 8 for driving the wide-width embroidery frame assembly 3 to move in the X-axis direction in the activity area 110, and a Y-axis drive assembly 7 for driving the wide-width embroidery frame assembly 3 to move in the Y-axis direction in the activity area 110.

[0061] In this patent, the single-head embroidery machine further includes an X-axis drive assembly 8 and a Y-axis drive assembly 7. The X-axis drive assembly 8 is used to drive the wide-width embroidery frame assembly 3 to move in the X-axis direction in the activity area 110, and the Y-axis drive assembly 7 is used to drive the wide-width embroidery frame assembly 3 to move in the X-axis direction in the activity area 110. Thus, the wide-width embroidery frame assembly 3 drives the wide-width fabric to move horizontally in the activity area 110, so that the needle assembly 5 passes the panel through a predetermined position on the wide-width fabric and cooperates with the shuttle box assembly 9 to lock the thread, completing the embroidery work.

[0062] Embodiment 1:

[0063] In this embodiment, the Y-axis driving assembly 7 includes a first guiding slide rail 71, a first belt driving member 72, and a first sliding seat 73. The first guiding slide rail 71 extends along the Y-axis direction on the frame 4. The first belt driving member 72 is arranged on the first guiding slide rail 71. The first sliding seat 73 is arranged on the transmission belt of the first belt driving member 72 and is slidably connected to the first guiding slide rail 71. Thus, when the transmission belt of the first belt driving member 72 rotates, the first sliding seat 73 is driven to move in the Y-axis direction along the first guiding slide rail 71.

[0064] The X-axis driving assembly 8 includes a second guiding slide rail 81, a second belt driving member 82, and a second sliding seat 83. The second guiding slide rail 81 is fixedly connected to the first sliding seat 73 and extends in the X-axis direction. The second belt driving member 82 is arranged on the second guiding slide rail 81. The second sliding seat 83 is arranged on the transmission belt of the second belt driving member 82 and is slidably connected to the second guiding slide rail 81. The wide-width embroidery frame assembly 3 is fixedly connected to the second sliding seat 83.

[0065] Therefore, when the first sliding seat 73 moves in the Y-axis direction along the first guiding slide rail 71, the second guiding slide rail 81, the second belt driving member 82, the second sliding seat 83, and the wide-width embroidery frame assembly 3 are driven to move synchronously in the Y-axis direction. When the transmission belt of the second belt driving member 82 rotates and drives the second sliding seat 83 to move in the X-axis direction along the second guiding slide rail 81, the wide-width embroidery frame assembly 3 is driven to move synchronously in the X-axis direction, thereby realizing the horizontal movement of the wide-width embroidery frame assembly 3 on the support platform 2 and ensuring the stability of the operation of the wide-width embroidery frame assembly 3.

[0066] In this embodiment, guiding slide seats 84 are arranged at both ends of the second guiding slide rail 81. The two guiding slide seats 84 are respectively slidably connected to the two side edges of the support platform 2. Thus, when the Y-axis driving assembly 7 drives the X-axis driving assembly 8 to move in the Y-axis direction, the movement of the second guiding slide rail 81 in the Y-axis direction is guided by the two guiding slide seats 84, thereby improving the stability of the movement of the X-axis driving assembly 8 in the Y-axis direction and further improving the stability of the operation of the wide-width embroidery frame assembly 3.

[0067] Specifically, in this embodiment, the guiding slide seat 84 can adopt a U-shaped slide seat. The U-shaped groove of the U-shaped slide seat faces the support platform 2 and is slidably matched with the side edge of the support platform 2, thereby reducing the vibration of the second guiding slide rail 81 when moving in the Y-axis direction and improving the stability of the movement of the X-axis driving assembly 8 in the Y-axis direction.

[0068] Further, a flexible pad can be arranged on the inner side of the U-shaped sliding seat, such as a felt pad, a rubber pad, etc. It can not only reduce the wear caused by the sliding fit between the U-shaped sliding seat and the side of the support platform 2, but also further buffer the vibration when the second guiding slide rail 81 moves in the Y-axis direction, thereby improving the running stability of the wide-width embroidery frame assembly 3.

[0069] Embodiment 2:

[0070] In this embodiment, the Y-axis driving assembly 7 includes two first guiding slide rails 71, two first belt driving members 72 and two first sliding seats 73. The two first guiding slide rails 71 extend along the Y-axis direction on the support platform 2. The two first belt driving members 72 are respectively arranged on the two first guiding slide rails 71. The two first sliding seats 73 are respectively arranged on the driving belts of the two first belt driving members 72 and are respectively slidably connected to the two first guiding slide rails 71. Thus, through the rotation of the driving belts of the two first belt driving members 72, the two first sliding seats 73 are driven to move in the Y-axis direction along the two first guiding slide rails 71 respectively.

[0071] The X-axis driving assembly 8 includes a second guiding slide rail 81, a second belt driving member 82 and a second sliding seat 83. The second guiding slide rail 81 extends along the X-axis direction on the support platform 2, and the two ends of the second guiding slide rail 81 are respectively fixedly connected to the two first sliding seats 73. The second belt driving member 82 is arranged on the second guiding slide rail 81. The second sliding seat 83 is arranged on the driving belt of the second belt driving member 82. The wide-width embroidery frame assembly 3 is fixedly connected to the second sliding seat 83.

[0072] When the two first sliding seats 73 move in the Y-axis direction along the two first guiding slide rails 71 respectively, the second guiding slide rail 81, the second belt driving member 82, the second sliding seat 83 and the wide-width embroidery frame assembly 3 are driven to move in the Y-axis direction synchronously; when the driving belt of the second belt driving member 82 rotates to drive the second sliding seat 83 to move in the X-axis direction along the second guiding slide rail 81, the wide-width embroidery frame assembly 3 is driven to move in the X-axis direction synchronously, thereby realizing the movement of the wide-width embroidery frame assembly 3 in the horizontal direction on the support platform 2 and ensuring the running stability of the wide-width embroidery frame assembly 3.

[0073] Since this single-head embroidery machine is applicable to large-format embroidery and the moving stroke of the wide-width embroidery frame assembly 3 is large, the lengths of the first guiding slide rail 71, the second guiding slide rail 81, the first guiding slide rail 71 and the second guiding slide rail 81 are large. In Embodiment 1, the first guiding slide rail 71 is arranged along the Y-axis direction on the frame 4, and the second guiding slide rail 81 is arranged along the X-axis direction on the first sliding seat 73. In order to ensure the movement stability of the wide-width embroidery frame assembly 3, the dimensions of the frame 4 in the Y-axis direction and the X-axis direction need to be increased accordingly, thereby increasing the production cost of this single-head embroidery machine.

[0074] In the second implementation, the first guiding slide rail 71 is arranged on the support platform 2 along the Y-axis direction, and the second guiding slide rail 81 is arranged on the support platform 2 along the X-axis direction, so as to not only ensure the stability of the operation of the wide-format embroidery frame assembly 3, but also increase the size of the frame 4, thereby reducing the production cost. Specifically, during implementation, according to the actual production situation, two implementation methods of the Y-axis driving assembly 7 and the X-axis driving assembly 8 can be selected.

[0075] It can be foreseen that: in this patent, both the first belt driving member 72 and the second belt driving member 82 include a driving wheel and a driven wheel arranged at a relative interval, a transmission belt sleeved on the driving wheel and the driven wheel, and a driving motor connected to the driving wheel. The driving motor drives the driving wheel to rotate, and through the cooperation of the transmission belt with the driving wheel and the transmission belt with the driven wheel, the driven wheel and the transmission belt are driven to rotate synchronously.

[0076] In this embodiment, the wide-format embroidery frame assembly 3 includes a frame body 31 and a connecting plate 32. The connecting plate 32 connects the frame body 31 to the second sliding seat 83 or the second sliding seat 83. A hollow area is provided in the middle of the frame body 31, and this area is the wide-format fabric embroidery area 311. A material laying groove 312 is provided on the outer periphery of the wide-format fabric embroidery area 311, and a convex portion 313 is provided on the material laying groove 312.

[0077] When fixing the wide-format fabric on the wide-format embroidery frame assembly 3, the wide-format fabric is laid in the material laying groove 312. The convex portion 313 on the material laying groove 312 jacks up the wide-format fabric, and then through the cooperation of a plurality of cloth clips with the convex portion 313, the wide-format fabric is clamped on the convex portion 313, thereby realizing the fixation of the wide-format fabric on the frame body 31.

[0078] During embroidery, the needle assembly 5 drives the surface thread to pass through the wide-format fabric located in the wide-format fabric embroidery area 311, thereby forming a pattern on the wide-format fabric. Specifically, during actual implementation, serrated protrusions are provided on the outer periphery of the convex portion 313. When fixing the wide-format fabric on the wide-format embroidery frame assembly 3, through the cooperation of a plurality of cloth clips with the serrated protrusions on the outer periphery of the convex portion 313, the fixation of the wide-format fabric on the wide-format embroidery frame assembly 3 is made more stable, ensuring the quality of the embroidered product.

[0079] In this embodiment, the single-head embroidery machine further includes a driving mechanism 10. The driving mechanism 10 drives the needle assembly 5 to move vertically on the frame 4, and at the same time drives the rotary shuttle in the shuttle box assembly 9 to lock the surface thread. It can be foreseen that: in this patent, the single-head embroidery machine further includes a thread stand and a thread clamp. The thread stand is arranged on the top of the frame 4 for carrying the thread bobbin, and the thread clamp is arranged on the frame 4 and is located between the thread stand and the needle assembly 5, so as to guide the surface thread of the thread bobbin to the needle assembly 5 and provide tension for the surface thread.

[0080] In this patent, the needle assembly 5 includes a thread take-up lever, a needle bar, and a presser foot. The upper thread, guided by the thread clamp, passes through the thread hole near the needle tip and is secured. When embroidering, the drive mechanism 10 drives the thread take-up lever, needle bar, and presser foot to synchronously move up and down vertically on the frame 4. As the needle bar moves downward, the needle tip pierces the wide fabric, driving the upper thread, which has a certain degree of tension, through the wide fabric. Simultaneously, the drive mechanism 10 drives the rotary hook in the shuttle box assembly 9 to rotate, causing the rotary hook to wrap around the bottom thread on the panel to form a knot, thereby completing the thread locking action.

[0081] Since the completion of the thread locking action requires the cooperation of the needle bar and the rotary hook, in this patent, the driving mechanism 10 drives the needle assembly 5 to move in the vertical direction on the frame 4 while driving the rotary hook in the shuttle box assembly 9 to rotate, thereby improving the synchronization of the operation of the needle assembly 5 and the shuttle box assembly 9, and thus ensuring the stability of the single-head embroidery machine.

[0082] In this embodiment, the driving mechanism 10 includes a lower shaft 101 arranged in the connecting column 6, an upper shaft 102 arranged in the frame 4, a power member 103 arranged between the upper shaft 102 and the lower shaft 101, a third belt driving member 104 connecting the lower shaft 101 and the power member 103, a fourth belt driving member 105 connecting the upper shaft 102 and the power member 103, and a fifth belt driving member 106 connecting the lower shaft 101 and the shuttle box body assembly 9, and the upper shaft 102 is connected to the needle assembly 5.

[0083] In this patent, the connecting column 6 and the frame 4 are both hollow structures, and the driving mechanism 10 includes a lower shaft 101, an upper shaft 102, a power member 103, a third belt driving member 104, a fourth belt driving member 105, and a fifth belt driving member 106. The lower shaft 101 is arranged in the connecting column 6, the upper shaft 102 is arranged in the frame 4, the power member 103 is arranged between the lower shaft 101 and the upper shaft 102, the third belt driving member 104 connects the lower shaft 101 with the power member 103, the fourth belt driving member 105 connects the upper shaft 102 with the power member 103, the fifth belt driving member 106 connects the lower shaft 101 to the shuttle box assembly 9, and the upper shaft 102 is connected to the needle assembly 5.

[0084] Specifically, the power component 103 includes a driving motor and a driving shaft connected to the rotating shaft of the driving motor; the third belt driving component 104 includes a driving wheel mounted on the driving shaft, a driven wheel mounted on the lower shaft 101, and a transmission belt mounted on the driving wheel and the driven wheel; the fourth belt driving component 105 includes a driving wheel mounted on the driving shaft, a driven wheel mounted on the lower shaft 101, and a transmission belt mounted on the driving wheel and the driven wheel.

[0085] The fifth belt driving member 106 includes a driving wheel sleeved on the lower shaft 101, a connecting shaft rotatably connected to the shuttle box assembly 9, a driven wheel sleeved on the connecting shaft, and a transmission belt sleeved on the driving wheel and the driven wheel. Thus, when the driving motor is started, the rotation of the rotating shaft of the driving motor drives the upper shaft 102, the lower shaft 101 and the connecting shaft to rotate synchronously.

[0086] It can be foreseen that: a transmission mechanism for converting rotational motion into linear motion is provided in the needle assembly 5, such as a transmission mechanism in which a gear cooperates with a rack. Thus, the rotation of the upper shaft 102 drives the needle assembly 5 to reciprocate vertically on the frame 4 synchronously; a commutation mechanism is provided in the shuttle box assembly 9. Thus, the rotation of the connecting shaft drives the rotary shuttle to rotate in a direction perpendicular to the connecting shaft.
