DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the present invention, so as to fully understand the purpose, scheme and effect of the present invention. It should be noted that the embodiments and features in the embodiments of this application can be combined with each other without conflict.

[0026] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature, or it may be indirectly fixed or connected to the other feature. In addition, the descriptions of up, down, left, right, front, back, etc. used in the present invention are only relative to the relative positional relationship of the components of the present invention in the drawings.

[0027] In addition, unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art. The terms used in this specification are only for describing specific embodiments, not for limiting the present invention. The term "and / or" used herein includes any combination of one or more related listed items.

[0028] Reference Figure 1One embodiment of the present invention is a sewing device capable of processing curved sewing threads. In this embodiment, the device comprises a frame 1, a machine head 2, a traveling device 3, a rotating device 4, a pressing device 5 and a rotary shuttle device. The machine head 2, the traveling device 3 and the rotating device 4 are all arranged on the frame 1. The rotating device 4 includes a rotating member 40. A through hole 400 is provided on the side of the rotating member 40 adjacent to the machine head 1. The through hole 400 is the placement position of the material 7. The rotating member 40 can rotate relative to the machine head 2 and cooperate with the rotary shuttle device to complete the processing of the curved sewing thread. The pressing device 5 is used to press the material 7 to prevent the material 7 from shifting in position. The traveling device 3 can drive the rotating member 40 to move forward and backward, thereby adjusting the position of the machine head 1 relative to the material 7 to complete the processing of sewing threads in different positions.

[0029] like Figure 2 As shown, it also includes a support tube 10, which is located inside the rotating member 40, and a through hole 400 is located outside the support tube 10. The side of the support tube 10 adjacent to the through hole 400 is used to place the material 7 so that the material 7 can be supported during the processing.

[0030] Reference Figure 2 The walking device in this embodiment includes a second driving device 34, a driving belt 32, a driving shaft 30 and a pushing slide bar 31. The output end of the second driving device 34 is connected to the driving shaft 30, driving the driving shaft 30 to rotate, thereby driving the driving belt 32 connected to the driving shaft 30 to rotate. A first track is provided on the frame 1, and the pushing slide bar 31 is slidably connected to the first track. The driving belt 32 is connected to the pushing slide bar 31, driving the pushing slide bar 31 to move on the first track. Since one end of the pushing slide bar 31 is connected to the rotating member 40, the rotating member slidably connected to the second track on the frame 1 moves along the direction of movement of the driving belt 32.

[0031] Combination Figure 2 , Figure 3 and Figure 4 A transfer block 60 is provided on one side of the connecting member 6 adjacent to the push slide rod 31, and the other side of the connecting member 6 is abutted against a block 461 on the transmission block 46. The push slide rod 31 pushes the transmission block 46, so that the connecting member 6 moves on the frame 1, thereby pushing the transmission block 46 to move, so that the rotating member 40 connected to the inner wall of the transmission block 46 moves along the moving direction of the push slide rod 31.

[0032] In order to better control the movement of the rotating member 40 in the front-to-back direction, in this embodiment, the number of the push slide rod 31 and the drive belt 32 is two, which are respectively arranged at the left and right ends of the rotating member 40, and are driven by a second drive device 34 to ensure that the driving force at both ends is consistent and no additional torque is generated on the rotating member 40.

[0033] like Figure 2 and Figure 3 As shown, the rotating device includes a rotating member 40, a first driving device 42, a belt 44 and a transmission group 45. The first driving device 42 is connected to the frame 1 through a connecting plate 41. The first driving device 42 is connected to the transmission shaft 43 through the transmission group 45, so that the transmission shaft 43 rotates under the drive of the first driving device 42. The other end of the transmission shaft 43 drives the belt 44 to rotate through a roller. The other end of the belt is connected to the outer wall of the transmission block 46, so that the transmission block 46 rotates under the drive of the belt, thereby driving the rotating member 40 connected to the inner wall of the rotating block 46 to rotate.

[0034] As an embodiment, it also includes a clamping wheel, such as Figure 3 As shown, the pressure wheel 9 is located on the outer side of the belt 44 connected to the transmission shaft 43 and contacts the belt 44 . The pressure wheel 9 applies pressure to the belt 44 , so that the connection between the belt 44 and the transmission shaft 43 is tighter.

[0035] Since the first driving device 42 is connected to the frame 1 through the connecting plate 41, the first driving device 42 can drive the rotating member 40 to rotate without increasing the weight of the rotating member 40. Compared with the sewing equipment in which the first driving device 42 is installed on the rotating member 40, the beneficial effect of this structure is that the weight of the rotating member 40 is reduced, the inertia of the rotating member 40 during the movement of the rotating member 40 is reduced, the rotation of the rotating member 40 is more stable, and the sewing thread processed by the rotary shuttle structure is more beautiful.

[0036] Combination Figure 3 and Figure 4 The transmission group 45 is a gear group, one end of the gear group is sleeved on the output end of the first driving device 42, and the other end is sleeved on the transmission shaft 43, so that the rotation of the transmission shaft 43 is driven by the first driving device 42.

[0037] Reference Figure 3, this embodiment also includes a material pressing device 5, which includes an intermediate support plate 50, an intermediate pressure plate 51 and a third driving device 52. One end of the intermediate support plate 50 is fixed on the rotating member 40, and the other end is suspended on the rotating member 40 at a position corresponding to the through hole 400 of the rotating member. The side of the intermediate support plate 50 adjacent to the machine head 1 is used to support the material. The intermediate pressure plate 51 is arranged on the intermediate support plate 50, which can press the intermediate support plate 50 to press the material, or move away from the intermediate support plate 50 to loosen the pressing of the material. The third driving device 52 is fixed on the rotating member 40, and its output end is fixedly connected to the intermediate pressure plate 51 to drive the intermediate pressure plate 51 to press or loosen the material. In this embodiment, the third driving device 52 is a cylinder. Since all the parts on the material pressing device 5 in this mechanism are all installed on the connecting member, the material pressing device 5 will not generate pressure on the rotating member 40, thereby causing the problem of large inertia in the rotation of the rotating member 40.

[0038] In order to better compact the material, the present embodiment also includes an auxiliary pressing device 8, such as Figure 3 As shown, the auxiliary pressing device 8 is used to press the material 7 at both ends, so as to ensure that the entire material 7 is in a pressed state and prevent the material 7 from being offset during the processing. The auxiliary pressing device 8 includes an auxiliary support plate 80, an auxiliary pressing plate 81 and a fourth driving device 82. The output end of the fourth driving device 82 is fixedly connected to the auxiliary pressing plate 81 to drive the auxiliary pressing plate 81 to press or loosen the material. One end of the auxiliary supporting plate 80 is connected to the rotating member 40, and the other end is located at the through hole 400. The auxiliary supporting plate 80 is used to support the side end of the material. The auxiliary pressing plate 81 can apply pressure to the material by pressing the auxiliary supporting plate 80 to press the material, or make the auxiliary supporting plate 80 loosen the pressure on the material. The fourth driving device 82 is fixed on the rotating member 40 so that it can rotate with the rotation of the rotating member 40, so as to ensure that the material 7 is always in a pressed state.

[0039] like Figure 3 As shown, the present embodiment includes two sets of auxiliary material pressing devices 8 , which are respectively arranged at the two ends of the material 7 to achieve compression of the two ends of the material 7 .

[0040] In order to adapt to materials of different types, the auxiliary pressing device of this embodiment also includes an adjustment plate 83, which is slidably set on the rotating member 40, and the adjustment plate 83 is fixedly connected to the auxiliary support plate 80. By adjusting the position of the adjustment plate 83 on the rotating member 40, the position of the auxiliary support plate 80 on the rotating member 40 can be adjusted, thereby realizing the adjustment of the position of the auxiliary pressing device 8, so that the auxiliary pressing device 8 can match materials of different sizes.

[0041] The method of using this embodiment is:

[0042] First, place the material 7 at the through hole 400 of the rotating member 40, and press the material 7 onto the rotating member 40 by the pressing device 5 and / or the auxiliary pressing device 8, and then drive the sliding rod 31 through the second driving device 34 to adjust the position of the rotating member 40 relative to the machine head 2, so that the material 7 located at the through hole 400 of the rotating member 40 is exactly located at the processing position of the machine head 1, and then the material 7 is processed by the cooperation of the machine head 1 and the rotary shuttle device.

[0043] As an embodiment, the transmission shaft 43 may be a spline, and this structure can reduce the overall weight of the sewing device.

[0044] Then, the transmission shaft 43 is driven to rotate by the first driving device 42 , thereby driving the rotating member 40 to rotate, thereby forming a sewing line on the material 7 .

[0045] The beneficial effects of this embodiment are:

[0046] 1. Through the cooperation of the rotating member 40, the machine head 1 can process a larger range on the material 7, or process a circular arc sewing line.

[0047] 2. Since the first driving device 42 is arranged on the frame 1, the weight on the rotating part 40 is relatively small, which alleviates the problems of uneven sewing lines and short service life of the equipment caused by the large inertia of the rotating part 40 during the processing.

[0048] 3. The above structure reduces the weight of the rotating parts, so that the structure can be better integrated with the electronic control system and better controlled by other structures.

[0049] The above is a specific description of the preferred implementation of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
