[0002] In the garment manufacturing industry, button sewing is a crucial step in production, and the use of automatic button sewing machines has significantly improved efficiency. However, existing automatic button sewing machines have numerous shortcomings in their feeding structure and performance. Traditional automatic button sewing machines have a relatively simple feeding structure, and during the gripping and transfer of clothing, the material is prone to shifting and slipping, resulting in inaccurate button placement and a high rate of defective products.

[0003] At the same time, the clamping jaw assembly of traditional button-stitching machines lacks flexibility, making it difficult to adapt to different sizes and materials.

Specific embodiments

[0036] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0037] The purpose of the present invention is to provide an automatic button sewing machine to solve the problems of the versatility, stability and working efficiency of the button sewing machine equipment.

[0038] As Figure 1As shown, the utility model provides an automatic button-stitching machine, comprising a frame, a machine head 1 arranged on the frame, and a feeding structure located below the frame and on the lower side of the machine head 1. An opening and closing plate 4 is provided on the frame, the machine head 1 is installed on one side of the opening and closing plate 4, and the feeding structure and the machine head 1 are on the same side. The feeding structure is composed of a clamping and feeding device 2 and a pressing device 3, wherein the clamping and feeding device 2 is responsible for conveying the clothes to be buttoned, and the machine head 1 automatically ties the clothes. The machine head 1 and the feeding structure are arranged on the same side, so that the operator does not need to frequently operate around the machine when changing the silk thread, and the operation path is shorter, which greatly improves the convenience of operation; the arrangement of the opening and closing plate 4, when the machine head 1 is installed, can provide a more spacious line changing space by opening the opening and closing plate 4, reducing the difficulty of line changing; in subsequent maintenance, it is also convenient to directly access the various components of the machine head 1 for inspection, saving maintenance time. The feeding structure is composed of the clamping and feeding device 2 and the pressing device 3. The two devices work together. The clamping and feeding device 2 first accurately delivers the clothes to the designated position, and the pressing device 3 then firmly presses the clothes, creating stable conditions for the button sewing work of the machine head 1, thereby realizing stable transportation and precise positioning of the clothes to be sewn with buttons, reducing the button sewing deviation caused by the change of the clothes position, improving the accuracy and stability of the button sewing, reducing the defective rate, and optimizing the overall structure to improve work efficiency.

[0039] like Figure 2 As shown, the material clamping and feeding device 2 includes a reciprocating motion component 21, a connecting component 22, and a first clamping jaw component 23, as well as a second clamping jaw component 24, a third clamping jaw component 25, and a fourth clamping jaw component 26 having the same structure as the first clamping jaw component 23. The first clamping jaw component 23 is movably connected to the connecting component 22, the second clamping jaw component 24 is arranged in parallel with the first clamping jaw component 23, the third clamping jaw component 25 is fixedly connected to the connecting component 22, and the fourth clamping jaw component 26 is arranged in parallel with the third clamping jaw component 25. The first clamping jaw component 23 and the third clamping jaw component 25 are arranged opposite to each other. A channel is provided on the frame, and the first clamping jaw component 23, the second clamping jaw component 24, the third clamping jaw component 25, and the fourth clamping jaw component 26 pass through the channel and move synchronously.

[0040] Specifically, such as Figure 3As shown, the first gripper assembly 23 comprises a hook 231, a base plate 232, a first cylinder 233, a radial rail 234, a push plate 235, and a second cylinder 236. The base plate 232 is fixedly connected to the connecting assembly 22. The fixed end of the radial rail 234 is fixedly connected to the base plate 232. The push plate 235 is connected to the sliding end of the radial rail 234. The second cylinder 236 is fixed to the base plate 232, and its output end is connected to the push plate 235. The middle portion of the hook 231 is rotatably connected to the push plate 235. One end of the hook is provided with a toothed hook that passes through a channel in the frame. The other end of the hook is provided with a drive unit that connects to the first cylinder 233. To pick up clothing, the second cylinder 236 drives the push plate 235 to slide along the radial rail 234, bringing the hook 231 closer to the clothing. The first cylinder 233 then controls the hook 231 through the drive unit to rotate around the push plate 235, allowing the toothed hook to accurately pick up the clothing. In addition, the first clamping jaw assembly 23 is also equipped with a return spring 237, one end of which is connected to the push plate 235 and the other end is connected to the base plate 232. After the hook 231 completes its action, the return spring 237 provides it with a return elastic force, helping the hook 231 to quickly and stably return to its original position. The first clamping jaw assembly 23 uses a structure that cooperates with a dual cylinder and a radial slide 234. The second cylinder 236 drives the push plate 235 to slide on the radial slide 234, achieving the horizontal movement of the hook 231 toward or away from the material. This movement can be flexibly adjusted according to the initial position of the material. The first cylinder 233 controls the rotation of the hook 231 around the push plate 235, allowing the tooth hook portion to fit the surface of the material at different angles for precise grasping, whether it is flat fabric or fabric with certain wrinkles. The dual-action coordinated control method greatly improves the adaptability of the clamping jaw assembly to fabrics of different sizes, shapes, and materials. The return spring 237 prevents the hook 231 from shifting in position due to inertia or external force after completing the action, ensuring that it can return to the exact initial position after each action, preparing for the next clamping action, ensuring the continuity and accuracy of the clamping action, thereby improving the reliability and versatility of the clamping and reducing production interruptions caused by clamping errors.

[0041] Furthermore, a first claw member 27 is provided below the first and second jaw assemblies 23 and 24, and a second claw member 28 is provided below the third and fourth jaw assemblies 25 and 26. The first and second claw members 27 and 28 have identical structures. Taking the first claw member 27 as an example, it includes a connecting block 271 and a claw 272 fixedly connected to the connecting block 271. The connecting block 271 is adjustably connected to the base plate 232. The claw 272 has teeth at both ends, which extend through the channel and are located below the toothed hook portion. The adjustable connection between the connecting block 271 and the base plate 232 allows the claw 272 to be flexibly adjusted according to the thickness, width, and other dimensions of the fabric. When clamping thicker fabric, the claw 272 can be adjusted to an appropriate height to ensure an effective clamping space with the toothed hook portion of the claw 231. When clamping fabrics of varying widths, the claw 272 and the toothed hook portion can also be adjusted to ensure that the force is evenly applied to both sides of the fabric. The teeth on both ends of the claw 272 cooperate with the teeth of the hook 231 to increase friction with the surface of the fabric. During the gripping process, even if the fabric surface is relatively smooth, this effectively prevents the fabric from slipping, ensuring the stability of the fabric during transfer. Stable fabric transfer allows the machine head 1 to accurately align the buttons at the desired position during sewing, further improving the quality of the sewing process.

[0042] In actual clothing production, the width and shape of the fabric corresponding to the button position of different styles of clothing are different. By adjusting the slide rail 222, the bottom plate 232 can drive the first clamping claw assembly 23 to slide on the connecting main plate 221, thereby adjusting the distance between the clamping claw assemblies. Figure 4 The connecting component 22 includes a connecting main board 221 and an adjusting slide rail 222 provided on one side of the connecting main board 221. The bottom plate 232 is fixedly connected to the sliding end of the adjusting slide rail 222, and the fixed end of the adjusting slide rail 222 is fixed to the connecting main board 221. By adjusting the fixed position of the bottom plate 232 and the adjusting slide rail 222, adaptation to the size of different fabrics is achieved (the fixing method is the existing technology, such as using a thread to pass through the bottom plate 232 to fix it to the adjusting slide rail 222, etc., which is not limited in this application), so that the material clamping and feeding device 2 can adapt to the clamping and transfer requirements of fabrics of different specifications, enhance the applicability and flexibility of the material clamping and feeding device 2, expand the application range of the automatic button sewing machine in diversified clothing production scenarios, and improve the versatility of the automatic button sewing machine.

[0043] In addition, in actual work, the gripper assembly needs to transfer the fabric between different workstations such as the waiting area, button sewing area, and discharge area. The stable and precise linear reciprocating motion enables the gripper assembly to accurately reach each workstation every time, ensuring the accuracy and consistency of fabric transfer. Figure 2-Figure 4The reciprocating assembly 21 includes a lower support plate 211, a drive motor 212, a drive rack 213, and a movable guide rail 214. The lower support plate 211 is arranged below the frame. The drive motor 212 passes through the lower support plate 211. Its output end is provided with a gear 215 corresponding to the drive rack 213. The gear 215 is meshed and connected with the drive rack 213. The drive rack 213 is fixedly connected to the connecting main board 221. The fixed end of the movable guide rail 214 is fixed to the lower support plate 211, and the sliding end is fixed to the connecting main board 221. The drive motor 212 serves as a power source. Through the meshing transmission of the gear 215 and the drive rack 213, the rotational motion of the motor is converted into linear motion, which can effectively transmit the power of the motor to the connecting assembly 22. The movable guide rail 214 provides a precise guide for the movement of the connecting main board 221, limits the deviation of the connecting main board 221 during the movement, and ensures that it can only move along a predetermined straight line trajectory. It ensures that the button sewing process can be carried out efficiently according to the predetermined process, improves the working efficiency and automation level of the automatic button sewing machine, and reduces the time for manual intervention and adjustment.

[0044] During the actual binding process, the first clamping assembly 23 and the second clamping assembly 24, the third clamping assembly 25 and the fourth clamping assembly 26 work together, pass through the channel on the frame and move synchronously, and efficiently complete the grabbing and transfer of the clothes.

[0045] like Figure 5 As shown, the pressing device 3 includes a mounting seat 31, a pressing drive device 32, a pressing arm 33 and a pressing component 34. The mounting seat 31 is set on the frame and can reciprocate along the direction of the machine head 1. The middle part of the pressing arm 33 is rotatably connected to the mounting seat 31. One end of the pressing drive device 32 is fixedly connected to the mounting seat 31, and the other end is connected to the pressing arm 33. The other end of the pressing arm 33 is connected to the pressing component 4. The pressing component 34 is at the end of the channel and is arranged adjacent to the channel.

[0046] Specifically, the press arm 33 includes a pivoting arm 331 and a pry bar 332. The middle portion of the pivoting arm 331 is rotatably connected to the mounting base 31. One end of the pivoting arm 331 is connected to the press drive 32, and the other end is provided with an adjustment slot 3311. The pry bar 332 is movably connected to the adjustment slot 3311, and the end of the pry bar 332, away from the pivoting arm 331, is connected to the press member 34. The press drive 32 rotates the pivoting arm 331, which, through the principle of leverage, causes the pry bar 332 to swing. The press drive 32 outputs a relatively small driving force, which acts on the pivoting arm 331. Because the pivoting arm 331 and the mounting base 31 form a lever structure, the lever principle generates a relatively large force at one end of the pry bar 332 (one end of the pry bar 332 is inserted into the sliding block 342), thereby achieving a relatively large clamping force with a relatively small driving force. The presence of the adjustment slot 3311 allows the connection position of the pry bar 332 on the pivoting arm 331 to be adjusted according to actual conditions. When dealing with fabrics of varying thicknesses, the position of the lever arm is adjusted by adjusting the position of the pry bar 332 in the adjustment slot 3311, thereby changing the position of the lever arm and, in turn, adjusting the clamping force of the pressing member 34. For fabrics of varying materials, such as soft silk and harder cloth, the angle of the pressing member 34 can be adjusted to press the fabric at the appropriate angle and force, ensuring effective compression and fixation of the fabric under various working conditions, thereby enhancing the applicability of the pressing device 3. After the pressing device 3 has exchanged and clamped the fabric, the movable structure on the machine head 1 (which utilizes existing machine head binding technology and is not described in detail herein) drives the mounting base 31 to move, thereby performing the sewing and binding.

[0047] Further, such as Figure 6 As shown, the press member 34 includes a press connecting plate 341, a sliding block 342, an upper press group 343, and a lower press group 344. The press connecting plate 341 is fixedly connected to the mounting base 31. One end of the sliding block 342 is slidably connected to the press connecting plate 341 and the other end is fixedly connected to the upper press group 343. The lower press group 344 is fixed below the upper press group 343. The pry bar 332 passes through the press connecting plate 341 and is connected to the sliding block 342. When the pry bar 332 swings, it drives the sliding block 342 to slide up and down, causing the upper press group 343 to open and close relative to the lower press group 344. When the pry bar 332 swings, the swinging action is converted into the up and down sliding of the sliding block 342 through the connection with the sliding block 342, thereby realizing the opening and closing movement of the upper pressing group 343 and the lower pressing group 344. This structural design makes the pressing action more flexible and precise, and can accurately control the size of the clamping force according to the thickness of the fabric and the requirements of the button sewing.

[0048] like Figure 7As shown in the figure, the upper material pressing group 343 includes a U-shaped outer upper frame 3431 and a vertical L-shaped inner upper frame 3432, and the lower material pressing group 344 includes a horizontal L-shaped outer lower frame 3441 and an inner lower frame 3442. One end of the notch of the U-shaped outer upper frame 3431 is fixedly connected to the slider, and the other end is located between the first jaw assembly 23 and the second jaw assembly 24. The horizontal L-shaped outer lower frame 3441 is directly below the U-shaped outer upper frame 3431 and the notch faces the material clamping and feeding device 2. One end of the vertical L-shaped inner upper frame 3432 is fixedly connected to the slider, and the other end is located between the channel and the mounting seat 31. The inner lower frame 3442 is directly below the vertical L-shaped inner upper frame 3432. Moreover, the width of the U-shaped outer upper frame 3431 is greater than the maximum distance between the first jaw assembly 23 and the second jaw assembly 24, and the width of the vertical L-shaped inner upper frame 3432 is less than the minimum distance between the first jaw assembly 23 and the second jaw assembly 24. When the material clamping and feeding device 2 transfers the clothing material, the space formed by the U-shaped outer upper frame 3431 and the horizontal L-shaped outer lower frame 3441 provides sufficient accommodation and guiding space for the clothing material, avoiding interference between the clothing material and the material pressing member 34 during the transfer process, and ensuring that the clothing material can be smoothly delivered to the buttoning position. When the material pressing operation is performed, the vertical L-shaped inner upper frame 3432 and the inner lower frame 3442 stably clamp the clothing material from different directions, ensuring that the clothing material will not be displaced or deformed during the buttoning process. By reasonably setting the dimensional relationships of each component, such as the width of the U-shaped outer upper frame 3431 being greater than the maximum distance of the jaw assembly and the width of the vertical L-shaped inner upper frame 3432 being less than the minimum distance of the jaw assembly, it not only ensures that the jaw assembly can smoothly transfer the clothing material, but also enables the material pressing member 34 to effectively press and fix the clothing material during the handover, further improving the working efficiency and buttoning quality of the buttoning machine. The U-shaped outer upper frame 3431 of the present utility model can be an integral structure or a split connection, which is prior art and is not limited herein in this application.

[0049] Furthermore, in order to enable the clothing material to quickly leave the working area after buttoning is completed, avoiding the accumulation of the clothing material at the buttoning station and affecting the subsequent transportation and buttoning operations of the clothing material. As Figure 1 、 Figure 8 shown in the figure, the present utility model further provides a pushing device 5. The pushing device 5 includes a cross driving member 51 and a pushing pull plate 52. The cross driving member 51 is fixedly connected to the machine head 1, and the cross driving member 51 is fixedly connected to the pushing pull plate 52, and is used to pull out the clothing material after binding is completed. When the machine head 1 completes the buttoning process of the clothing material, the cross driving member 51 is started to drive the pushing pull plate 52 to act. The pushing pull plate 52 contacts the clothing material and applies a pulling force to pull out the buttoned clothing material from the buttoning station. The cross driving member 51 (such as a cross slide table) is prior art and is not limited herein in this application.

[0050] The above disclosure is merely one or more preferred embodiments of the present application and is not intended to limit the scope of the present application. A person skilled in the art will understand that all or part of the processes of the above embodiments and equivalent changes made in accordance with the claims of the present application are still within the scope of the present application.
