Description

Technical Field

[0001] This invention relates to the field of bead-attaching machines, and more specifically to a fully automatic bead-attaching machine. Background Technology

[0002] A beading machine is a specialized piece of equipment used to attach decorative beads to clothing, bags, shoes, hats, leather goods, and other products. It is widely used in garment processing, bag manufacturing, shoe production, and leather goods processing. With the rapid development of the garment and bag industry, the market demand for beaded products continues to grow, and users are placing increasingly higher demands on the production efficiency, operational stability, and cost control of beading machines.

[0003] In existing bead-attaching machines, the bead-attaching structure and the nail-attaching structure typically require separate drive mechanisms, with each mechanism controlling the movement of the bead-attaching rod and the nail-attaching rod respectively. However, this dual-drive mechanism approach has the following drawbacks: First, the two drive mechanisms consume a significant amount of electrical energy, leading to higher production costs. This is especially true in a market environment where bead-attaching processing prices are continuously declining, making the impact of electricity costs on profit margins increasingly prominent. Second, since the bead-attaching and nail-attaching structures are driven by different mechanisms, precise timing coordination control is required to ensure proper coordination between the bead-attaching and nail-attaching processes. This increases control complexity and makes synchronization deviations prone to occur. If the bead-attaching rod rises too early, causing the bead to fail to effectively seal the bead hole, the nail-attaching rod pushing the nail upward can cause the nail to bounce off the top of the bead hole, resulting in bead-attaching failure and affecting product quality and production safety. Summary of the Invention

[0004] This invention provides a fully automatic bead-attaching machine, including a drive mechanism, a bead-attaching mechanism, a nail-attaching mechanism, and a bead-attaching seat.

The positioning wheel is set on the turntable and in the limiting groove. The limiting groove is connected to the ball punch rod. The driving link drives the turntable to rotate, and the turntable drives the positioning wheel to rotate. The positioning wheel moves back and forth along the limiting groove, causing the limiting groove to rise and fall, thereby cooperating with the sliding structure to drive the ball punch rod to rise and fall. The limiting groove is provided with a downwardly recessed arc-shaped groove. The positioning wheel moves along the arc-shaped groove. Before it reaches the lowest point of the arc-shaped groove, the ball punch rod descends and reaches the predetermined position of the ball punching process.

[0007] Preferably, the guiding structure includes a cam and a guide groove surrounding the cam. One end of the drive linkage is connected to the cam. The positioning wheel is fixed on the sliding structure. The sliding structure is connected to the ball-punching rod. The positioning wheel is set in the guide groove and close to the cam.

[0009] Preferably, the transmission structure includes a first transmission belt, a first driven pulley, a second transmission belt, and a second driven pulley. The first transmission belt connects the drive motor and the first driven pulley. The first driven pulley is connected to the drive linkage. The second transmission belt connects the drive linkage and the second driven pulley. The second driven pulley is connected to the punch transmission structure.

[0010] Preferably, the operating table includes an X-axis drive component and a Y-axis drive component, which drive the fabric to be beaded to move within the operating table.

[0011] Preferably, multiple ball-ejecting components are also provided, and the ball-punching mechanism is provided with a lateral drive mechanism and a limiting kit. The lateral drive mechanism drives the ball-punching mechanism to move laterally between the multiple ball-ejecting components for switching.

[0012] Preferably, the punch drive structure consists of a drive shaft and an eccentric wheel, with the drive shaft connecting the second driven wheel and the eccentric wheel, and the output end of the eccentric wheel connected to the punch rod.

[0013] Preferably, the punch transmission structure includes a crank connecting rod, a drive swing arm, and a fulcrum.

[0014] Preferably, it also includes a pushing mechanism disposed on the punch rod, the pushing mechanism including a pushing motor and a pushing link, the pushing motor pushing the punch rod upward independently through the pushing link.

[0015] The beneficial effects of this invention are as follows: Using only a single drive motor, the ball-punching mechanism and the nail-punching mechanism are simultaneously driven through a transmission structure. Compared to the traditional dual-motor solution, this significantly reduces energy consumption and effectively lowers production electricity costs. In a market environment where the unit price of nail-punching processing continues to decline, this improvement directly increases product profit margins and enhances market competitiveness. The ball-operated rod descends to its position before the punch rod actuates, pressing the ball firmly and sealing the ball-operated hole. The punch rod then rises to push the nail through the blocked ball-operated hole, completing the nailing process. Because the ball-operated rod remains in the pressed position until the nailing action is complete, the nail is blocked by the ball and will not pop out from above the ball-operated hole. This fundamentally solves the nailing failure problem caused by the simultaneous movement of the ball-operated rod and the punch rod in the single-motor solution, significantly improving product yield. The beading process is fully automated by moving the fabric to be beaded within the control panel, eliminating the need for manual adjustment of the fabric position, thus improving production efficiency and reducing labor costs.

If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0023] In some embodiments of this application, a fully automatic bead-attaching machine includes a drive mechanism 21, a bead-punching mechanism 22, a nail-punching mechanism 23, a bead-punching seat 10, and an operating table 24. The bead-punching mechanism 22 pushes the beads downwards, and the nail-punching mechanism 23 pushes the nails upwards, completing the bead-attaching process on the bead-punching seat 10. The operating table 24 drags the fabric to be beaded on the operating table 24. The drive mechanism 21 includes a drive motor 1 and a transmission structure. The transmission structure includes a first transmission belt 2, a first driven pulley 3, a second transmission belt 25, and a second driven pulley 26. The bead-punching mechanism 22 includes a drive linkage 4, a positioning wheel 7, a bead-punching rod 8, a guide structure, and a sliding structure. The drive motor 1 drives the drive linkage 4 through the transmission structure. The positioning wheel 7 is configured to cooperate with the guide structure. The guide structure is connected to the sliding structure, and the sliding structure is connected to the bead-punching rod 8. When the drive linkage 4 rotates, it drives the positioning wheel 7 to move. The positioning wheel 7 drives the bead-punching rod 8 to rise and fall through the guide structure and the sliding structure. The punching mechanism 23 includes a punching transmission structure and a punching rod 16. The punching transmission structure is connected to the transmission structure, and the punching transmission structure is also connected to the punching rod 16. The drive motor 1 drives the punching transmission structure to work through the transmission structure, and the punching transmission structure drives the punching rod 16 to rise and fall. The operating table 24 can drag the fabric to be nailed to move on the operating table 24.

[0024] In practical implementation, the drive motor 1 provides the power source for the entire fully automatic bead-attaching machine. The transmission structure employs a two-stage transmission method: a first transmission belt 2 connects the drive motor 1 and the first driven pulley 3; when the drive motor 1 operates, the friction of the first transmission belt 2 drives the first driven pulley 3 to rotate. A second transmission belt 25 connects the drive linkage 4 and the second driven pulley 26; when the drive linkage 4 rotates, the second transmission belt 25 drives the second driven pulley 26 to rotate. Through the two-stage transmission belt setup, the power of the drive motor 1 is transmitted to the bead-attaching mechanism 22 and the nail-attaching mechanism 23 respectively, achieving independent drive and coordinated operation of the two actuators, with a clear and reliable motion relationship. The bead-attaching mechanism 22 pushes the beads into the bead-attaching hole 11 of the bead-attaching seat 10 to complete the bead-attaching process; the nail-attaching mechanism 23 pushes the nails from below the bead-attaching seat 10 into the bead-attaching hole 11, allowing the nails to pass through the beads to complete the bead-attaching process. The bead-attaching and nail-attaching processes are completed sequentially on the bead-attaching seat 10, jointly realizing the bead-attaching function. In the ball-punching mechanism 22, the drive link 4 rotates under the drive of the first driven wheel 3, and the positioning wheel 7 on the drive link 4 rotates accordingly. The positioning wheel 7 cooperates with the guide structure to convert the rotation of the positioning wheel 7 into the linear motion of the sliding structure. The sliding structure drives the ball-punching rod 8 to rise and fall, realizing the ball-punching action. In the punching mechanism 23, the second driven wheel 26 transmits power to the eccentric wheel through the transmission shaft 30. The eccentric wheel rotates with the transmission shaft 30, and the eccentric output end of the eccentric wheel pushes the punching rod 16 to move up and down, realizing the punching action. The operating table 24 is located below the ball-punching seat 10 and is mounted on the guide rail 13. The operating table 24 can move horizontally along the guide rail 13. The guide rail 13 is provided with a sliding groove 14, which guides the movement direction of the operating table 24 and ensures movement accuracy. The operating table 24 holds the fabric to be beaded and moves it horizontally along the X and Y directions via X-axis and Y-axis drive components, achieving fully automated beading operation. Figure 1 As shown, the entire fully automatic beading machine is driven by a single drive motor 1, which simultaneously drives the bead punching mechanism 22 and the bead punching mechanism 23. The operating table 24 carries the fabric to be beaded under the bead punching seat 10 and can move automatically without the need for manual adjustment of the fabric position.

[0025] like Figure 5-7 As shown, in some preferred embodiments of this application, the guiding structure is a limiting groove 5. A coaxially rotating turntable 6 is provided at one end of the drive linkage 4, and a positioning wheel 7 is mounted on the turntable 6 and positioned within the limiting groove 5. The limiting groove 5 is connected to the ball-punching rod 8. The drive linkage 4 drives the turntable 6 to rotate, which in turn drives the positioning wheel 7 to rotate. The positioning wheel 7 moves back and forth along the limiting groove 5, causing the limiting groove 5 to rise and fall, thereby cooperating with the sliding structure to drive the ball-punching rod 8 to rise and fall. The limiting groove 5 is provided with a downwardly recessed arc-shaped groove 9. The positioning wheel 7 moves along the arc-shaped groove 9, and before reaching the lowest point of the arc-shaped groove 9, the ball-punching rod 8 descends to the predetermined position for the ball-punching process.

[0026] In the specific implementation process, the turntable 6 and the drive linkage 4 are coaxially arranged. A positioning wheel 7 is eccentrically mounted on the turntable 6, and the positioning wheel 7 makes eccentric circular motion as the turntable 6 rotates. The limiting groove 5 is a component with a groove-shaped structure. The center of the limiting groove 5 is provided with a downwardly recessed arc-shaped groove 9, and the positioning wheel 7 is rotatably set in the limiting groove 5. When the drive linkage 4 drives the turntable 6 to rotate, the positioning wheel 7 makes circular motion in the limiting groove 5 and slides back and forth along the groove wall. When the positioning wheel 7 moves to the area of ​​the arc-shaped groove 9 of the limiting groove 5, the positioning wheel 7 slides down along the arc surface of the arc-shaped groove 9, causing the limiting groove 5 to gradually descend. The limiting groove 5 drives the ball punching rod 8 to descend through the sliding structure. Because the arc-shaped groove 9 has a smooth arc transition, the limiting groove 5 has descended a certain distance before the positioning wheel 7 reaches the lowest point of the arc-shaped groove 9, and the ball punching rod 8 has reached the predetermined position of the ball punching process, that is, the ball punching rod 8 has pushed the ball to seal the ball punching hole 11. Subsequently, the positioning wheel 7 continues to slide along the arc-shaped groove 9 towards the lowest point, while the limiting groove 5 continues to descend slightly or remains at a lower position, and the punch rod 8 does not immediately rise and retract. The curvature of the arc-shaped groove 9 can be designed and adjusted according to the timing requirements of the punching and nailing processes. The smaller the radius of curvature of the arc-shaped groove 9, the slower the movement of the positioning wheel 7 near the lowest point, and the longer the punch rod 8 remains in the downward position. Using the above technical solution, through the cooperation of the limiting groove 5 and the turntable 6, the rotational motion of the drive linkage 4 is converted into the up-and-down reciprocating motion of the punch rod 8. The structure is simple and compact, and the motion is reliable. By setting the arc-shaped groove 9 in the limiting groove 5, the punch rod 8 reaches the predetermined position of the punching process before the positioning wheel 7 reaches the lowest point of the arc-shaped groove 9, and the punch rod 8 remains in the downward position without rising during the process of the positioning wheel 7 continuing to slide towards the lowest point, providing a reliable mechanical guarantee for the timing coordination of the punching and nailing processes.

[0027] like Figure 8-10 As shown, in some preferred embodiments of this application, the guide structure includes a cam 18 and a guide groove 19 surrounding the cam 18. One end of the drive linkage 4 is connected to the cam 18. The positioning wheel 7 is fixed to the sliding structure, which is connected to the ball-punching rod 8. The positioning wheel 7 is disposed within the guide groove 19 and close to the cam 18. When the cam 18 rotates, the positioning wheel 7 follows the rotation of the cam 18, rising and falling along the sliding structure. The guide groove 19 has a downwardly recessed arc-shaped groove 9. The positioning wheel 7 moves along the arc-shaped groove 9. Before reaching the lowest point of the arc-shaped groove 9, the ball-punching rod 8 descends, reaching the predetermined position for the ball-punching process.

[0028] In the specific implementation process, cam 18 is fixedly installed at one end of drive link 4 and rotates synchronously with drive link 4. The outer contour of cam 18 is non-circular, with curved surfaces of different radii. When cam 18 rotates, different parts of its outer contour contact the positioning wheel 7 in sequence. The positioning wheel 7 is fixed on the sliding structure, which is connected to the ball bearing rod 8. The positioning wheel 7 is set in the guide groove 19 surrounding cam 18 and always closely follows the outer contour of cam 18. When cam 18 rotates to a part with a larger radius and contacts the positioning wheel 7, the positioning wheel 7 is pushed away from the center of rotation by cam 18, causing the sliding structure to move upward and the ball bearing rod 8 to rise; when cam 18 rotates to a part with a smaller radius, the positioning wheel 7 moves towards the center of rotation under the action of gravity or an elastic reset member, causing the sliding structure to move downward and the ball bearing rod 8 to descend. The guide groove 19 is provided with a downwardly recessed arc-shaped groove 9. When the positioning wheel 7 moves to the area of ​​the arc-shaped groove 9 in the guide groove 19, the positioning wheel 7 slides down along the arc-shaped groove 9, driving the ball-punching rod 8 to descend rapidly to the predetermined position of the ball-punching process. Moreover, the ball-punching rod 8 is already in place before the positioning wheel 7 reaches the lowest point of the arc-shaped groove 9. This cam 18 type guide structure can also realize the up-and-down reciprocating motion of the ball-punching rod 8, and the design of the cam 18 profile can precisely control the stroke and speed of the ball-punching rod 8.

[0029] like Figure 11-13 As shown, in some preferred embodiments of this application, the guide structure is a cam 18, and a spring 20 with an upward restoring force is provided on the positioning wheel 7. One end of the drive linkage 4 is connected to the cam 18, the positioning wheel 7 is fixed on the sliding structure, the sliding structure is connected to the ball bearing rod 8, the positioning wheel 7 is located below the cam 18, the spring 20 pulls the positioning wheel 7 to be close to the cam 18, and when the cam 18 rotates, the positioning wheel 7 follows the rotation of the cam 18 and rises and falls along the sliding structure.

[0030] In this implementation, unlike the aforementioned cam 18 scheme, the positioning wheel 7 is positioned below the cam 18 rather than surrounding it. The cam 18 is fixedly mounted on one end of the drive linkage 4 and rotates synchronously with the drive linkage 4. The outer contour of the cam 18 is non-circular, and its lowest point contacts the positioning wheel 7. The positioning wheel 7 is fixed to the sliding structure, which is connected to the ball-punching rod 8. One end of the spring 20 is fixed to the positioning wheel 7 or the sliding structure, and the other end is fixed to the frame of the ball-pinning machine. The spring 20 always applies an upward pulling force to the positioning wheel 7, ensuring that the positioning wheel 7 is always in close contact with the outer contour of the cam 18. When the cam 18 rotates to the point where its contour protrudes downward and contacts the positioning wheel 7, the positioning wheel 7 is pushed downward by the cam 18, causing the sliding structure to move downward and the ball-punching rod 8 to descend. When the cam 18 rotates to the point where its contour is concave upward, the positioning wheel 7 moves upward under the pulling force of the spring 20, causing the sliding structure to move upward and the ball-punching rod 8 to rise. The design of the outer contour of cam 18 allows for precise control of the stroke and speed of the ball-operated rod 8, ensuring it completes the ball-operated action according to the set timing. Compared to gravity-based reset, the reset force provided by spring 20 is more reliable and stable, ensuring that the positioning wheel 7 remains in contact with cam 18, thus improving motion accuracy and response speed.

[0031] In some preferred embodiments of this application, the transmission structure includes a first transmission belt 2, a first driven pulley 3, a second transmission belt 25, and a second driven pulley 26. The first transmission belt 2 connects the drive motor 1 and the first driven pulley 3, the first driven pulley 3 is connected to the drive linkage 4, the second transmission belt 25 connects the drive linkage 4 and the second driven pulley 26, and the second driven pulley 26 is connected to the punch transmission structure.

[0032] In some preferred embodiments of this application, the operating table 24 includes an X-axis drive component and a Y-axis drive component. The X-axis drive component and the Y-axis drive component drive the fabric to be beaded on the operating table 24 to move in the horizontal plane, thereby realizing fully automatic beading operation without the need for manual adjustment of the fabric position.

[0033] In some preferred embodiments of this application, a plurality of bead-ejecting parts 27 are provided, and a lateral drive mechanism and a limiting kit 31 are provided on the bead-punching mechanism 22. The lateral drive mechanism drives the bead-punching mechanism 22 to move laterally between the plurality of bead-ejecting parts 27 to switch, so that the bead-pinning requirements of different specifications of beads can be met on the same device.

[0034] In practice, multiple bead ejectors 27 are arranged laterally on the frame of the bead-attaching machine, with a predetermined spacing between adjacent ejectors 27. Each ejector 27 has punch holes 11 of different specifications or types, allowing for the placement of beads of different sizes or materials. A lateral drive mechanism is positioned above the punching mechanism 22, which moves the punching mechanism 22 along the lateral guide rail between the multiple ejectors 27. A limiting device 31 is used to limit the swing amplitude of the ejectors 27 in the front-to-back direction, ensuring stability during the punching process. When it is necessary to switch to beads of different specifications, the lateral drive mechanism is activated, driving the punching mechanism 22 to move along the lateral guide rail to the position aligned with the target ejector 27, thus enabling the bead-attaching operation of beads of different specifications.

[0035] In some preferred embodiments of this application, the punch transmission structure consists of a drive shaft 30 and an eccentric wheel. The drive shaft 30 connects the second driven wheel 26 and the eccentric wheel. The output end of the eccentric wheel is connected to the punch rod 16. The structural design of the eccentric wheel can achieve stable punching action.

[0036] In some preferred embodiments of this application, the punch transmission structure includes a crank connecting rod 17, a drive swing arm 15, and a fulcrum. The crank connecting rod 17 is connected to the transmission structure, and the drive swing arm 15 is rotatably mounted on the fulcrum. One end of the drive swing arm 15 is connected to the crank connecting rod 17, and the other end of the drive swing arm 15 is connected to the punch rod 16.

[0037] In the specific implementation, one end of the crank connecting rod 17 is connected to the output end of the transmission structure, and the other end of the crank connecting rod 17 is hinged to one end of the drive swing arm 15. The drive swing arm 15 is rotatably mounted on a fulcrum, which is fixedly mounted on the frame of the bead-pinning machine. The other end of the drive swing arm 15 is fixedly connected to the punch rod 16. When the crank connecting rod 17 reciprocates, the drive swing arm 15 swings around the fulcrum, and the other end of the drive swing arm 15 drives the punch rod 16 to move up and down, realizing the punching action.

[0038] In some preferred embodiments of this application, a rotational position sensor 12 is provided on the drive linkage 4, which is used to identify whether the ball bearing rod 8 has been reset.

[0039] In practical implementation, the rotary position sensor 12 is installed near the drive linkage 4 to detect the rotation angle or position of the drive linkage 4, thereby indirectly determining whether the ball-punching rod 8 has returned to the rising reset position, avoiding misoperation or equipment damage caused by the ball-punching rod 8 not resetting. The rotary position sensor 12 can also be used for counting functions to count the number of times the ball-punching rod 8 punches, facilitating production management and quality traceability.

[0040] In some preferred embodiments of this application, a pushing mechanism is also provided on the punch rod 16. The pushing mechanism includes a pushing motor 28 and a pushing link 29. The pushing motor 28 pushes the punch rod 16 upward through the pushing link 29.

[0041] In the specific implementation process, the pushing mechanism is set independently of the drive motor 1, and the control circuit of the pushing mechanism is independent of the control circuit of the drive motor 1. One end of the pushing rod 29 is connected to the output shaft of the pushing motor 28, and the other end of the pushing rod 29 is connected to the punch rod 16. When a ball becomes blocked in the ball hole 11, and the blockage cannot be cleared by controlling the punch rod alone because the ball rod 8 and the punch rod 16 have a synchronous linkage relationship, the pushing motor 28 is started independently, driving the pushing rod 29 to push the punch rod 16 upward. The punch rod 16 enters the ball hole 11, pushing the blocked ball upward in the ball hole 11, thus clearing the blockage.

[0042] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
