Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, specifically to a fabric clamping device for a computerized embroidery machine. Background Technology

[0002] In the textile, apparel, and home decoration industries, computerized embroidery machines are the core equipment for mass embroidery production. As a key component, the fabric clamping device must reliably fix the fabric during embroidery to prevent displacement, wrinkles, or loosening, which directly determines the embroidery precision, product quality, and overall production efficiency of the equipment. Most mainstream computerized embroidery machines currently use manual clamping devices, and the entire operation relies on manual labor: first, the fabric to be embroidered is laid flat on the worktable and its position is manually adjusted to ensure that the embroidery area is aligned with the needle position and the needle path; then, the fabric is mechanically pressed and fixed by manually rotating bolts, buckles, or pressure bars; after a single embroidery is completed, the structure must be manually loosened to remove the material, and the operation is repeated to clamp the next piece of fabric. However, manual clamping methods suffer from low production efficiency, time-consuming manual clamping and disassembly, a high proportion of auxiliary time in batch production, and a significant reduction in the effective operating time of the equipment. They are also labor-intensive, as operators need to continuously repeat actions such as flattening, adjusting, pressing, and picking up materials. Prolonged operation can easily lead to occupational health problems, and fatigue can further exacerbate accuracy and efficiency issues.

[0003] In view of the above, this application is hereby submitted. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: a fabric clamping device for a computer embroidery machine, including a rectangular plate 1. Clamping plates 2 are rotatably installed on the left and right sides of the top surface of the plate 1. A driving assembly is provided on the plate 1 to drive the clamping plates 2 to rotate and fix the fabric on the top surface of the plate 1. The driving assembly includes slide seats 3 slidably disposed on the left and right side walls of the plate 1. A connecting rod 4 is rotatably connected to the slide seat 3. The end of the connecting rod 4 away from the slide seat 3 is rotatably connected to the clamping plate 2. A movable rod 6 is connected between the two slide seats 3. A threaded rod 5 is rotatably installed inside the plate 1. The movable rod 6 is threadedly connected to the threaded rod 5. A drive motor 7 is installed on the rear side wall of the plate 1. The driving end of the drive motor 7 is connected to one end of the threaded rod 5.

[0017] Specifically, in the initial state, the clamping plate 2 is open, and the operator lays the fabric flat on the top surface of the platform 1; the drive motor 7 on the rear side wall of the platform 1 is started, and its drive end drives the threaded rod 5, which is rotatably installed inside the platform 1, to rotate; since the movable rod 6 is threadedly connected to the threaded rod 5, the rotation of the threaded rod 5 is converted into the linear motion of the movable rod 6, which in turn drives the two slide blocks 3 connected to the movable rod 6 to slide along the left and right side walls of the platform 1; the connecting rod 4 rotatably connected to the slide block 3 is linked to push the clamping plate 2, which is rotatably connected to its other end, to rotate around the top surface of the platform 1, and finally presses and fixes the fabric to the top surface of the platform 1.

[0018] As a technical optimization of this utility model, the length of the clamping plate 2 is the same as the narrow side of the table plate 1, and the material of the clamping plate 2 is stainless steel.

[0019] Specifically, during clamping, the clamping plate 2, which is the same length as the narrow side of the platform 1, can cover the fabric edges on the left and right sides of the platform 1. The stainless steel material ensures that the clamping plate 2 is not easily deformed or rusted during long-term rotation and pressing, and maintains a stable pressing force.

[0020] As a technical optimization of this utility model, a sliding plate 14 is slidably installed on the clamping plate 2. The sliding plate 14 is perpendicular to the clamping plate 2, and the bottom surface of the sliding plate 14 is flush with the bottom surface of the clamping plate 2. The fabric can be flattened by sliding the sliding plate 14. A transmission component for driving the sliding plate 14 to slide is provided on the clamping plate 2.

[0021] Specifically, when the fabric has wrinkles, the sliding plate 14 is driven to slide in a direction perpendicular to the clamping plate 2 by the transmission component on the clamping plate 2, and the sliding plate 14 smooths out the wrinkles of the fabric during the sliding process.

[0022] As a technical optimization of this utility model, the transmission assembly includes a bracket 9 installed on the top surface of the clamping plate 2. An electric push rod 10 is installed on the top surface of the bracket 9. A sliding block 11 is connected to the telescopic end of the electric push rod 10. The sliding block 11 is slidably connected to the bracket 9. A connecting rod 12 is hinged to the side wall of the sliding block 11. A wedge block 13 is provided on the clamping plate 2 and slides along its length direction. The end of the connecting rod 12 away from the sliding block 11 is rotatably connected to the wedge block 13. A support 15 is connected to the sliding plate 14. A guide post 16 is connected to the support 15. The end of the guide post 16 away from the support 15 abuts against the inclined surface of the wedge block 13.

[0023] Specifically, the electric push rod 10 on the top support 9 of the clamping plate 2 is activated, and its telescopic end pushes the sliding block 11 to slide along the support 9; the connecting rod 12 hinged to the side wall of the sliding block 11 rotates accordingly, causing the wedge block 13, which is rotatably connected to the other end of the connecting rod 12, to slide along the length direction of the clamping plate 2; the inclined surface of the wedge block 13 abuts against the guide post 16 connected to the support 15 on the sliding plate 14, and the thrust of the inclined surface pushes the guide post 16 to drive the sliding plate 14 to slide, thereby achieving fabric leveling.

[0024] As a technical optimization of this utility model, the top surface of the platform 1 is provided with a guide groove recessed along its length direction, and the bottom surface of the wedge block 13 is integrally formed with a guide block, which is slidably connected inside the guide groove.

[0025] Specifically, when the transmission assembly drives the wedge block 13 to slide, the guide block moves along the guide groove, restricting the sliding direction of the wedge block 13 and preventing it from deviating.

[0026] As a technical optimization of this utility model, a connecting seat 17 is also installed on the top surface of the sliding plate 14, and a return spring 18 is connected to the connecting seat 17. The end of the return spring 18 away from the connecting seat 17 is connected to the outer side wall of the clamping plate 2.

[0027] Specifically, after leveling is completed, the electric push rod 10 retracts, driving the transmission assembly to reset. At the same time, the reset spring 18 releases its elastic force, pulling the sliding plate 14 back to its initial position, preparing for the next leveling.

[0028] This computerized embroidery machine's fabric clamping device achieves automated fabric clamping and leveling through a collaborative working mode of "drive components driving clamping plates to fix the fabric + transmission components driving sliding plates to level the fabric." The specific working principle is as follows: Initial state: When the device is not started, the clamping plate 2 is in an open state with a certain angle to the top surface of the table 1, which makes it easy for the operator to lay the fabric to be embroidered flat on the top surface of the table 1. At this time, the slide 3 is in the initial position on the side wall of the table 1, and the movable rod 6 and the threaded rod 5 remain relatively stationary. Drive motor 7 starts transmission: After the fabric is laid flat, drive motor 7 on the rear side wall of the platform 1 is started. The drive end of drive motor 7 drives the threaded rod 5 connected to it to rotate inside the platform 1. Since the movable rod 6 is threadedly connected to the threaded rod 5, the rotation of the threaded rod 5 is converted into linear motion of the movable rod 6 along the length of the threaded rod 5. The slide block 3 and the connecting rod 4 work together to drive the clamping plate 2 to rotate: The two ends of the movable rod 6 are connected to the slide blocks 3 on the left and right side walls of the platform 1. When the movable rod 6 moves, it will simultaneously drive the two slide blocks 3 to slide along the side walls of the platform 1. The connecting rod 4, which is rotatably connected to the slide block 3, moves accordingly. Its end away from the slide block 3 is rotatably connected to the clamping plate 2, thereby pushing the clamping plate 2 to rotate downward around the rotation connection point on the top surface of the platform 1. Fabric clamping and fixing: When the clamping plate 2 rotates until the bottom surface of the fabric is completely in contact with the top surface of the table plate 1, the drive motor 7 is stopped. At this time, the clamping plate 2, which is made of stainless steel and has a length equal to the narrow side of the table plate 1, reliably fixes the fabric to the top surface of the table plate 1 through its own pressure, preventing the fabric from shifting during the embroidery process. Initial transmission of the transmission assembly: After the clamping plate 2 presses the fabric, if there are local wrinkles in the fabric, the electric push rod 10 on the top support 9 of the clamping plate 2 is activated. The telescopic end of the electric push rod 10 pushes the sliding block 11 connected to it, causing the sliding block 11 to slide along the length direction of the support 9. Link 12 and wedge block 13 are linked: Link 12, which is hinged to the side wall of sliding block 11, rotates as sliding block 11 moves. The end of link 12 away from sliding block 11 drives wedge block 13 to slide along the length of clamp plate 2. The guide block on the bottom surface of wedge block 13 slides in the guide groove on the top surface of platform 1 to ensure stable sliding direction. Sliding plate 14 moves to flatten the fabric: When wedge block 13 slides, its inclined surface abuts against guide post 16 connected to support 15 on sliding plate 14. The thrust of the inclined surface pushes guide post 16, causing sliding plate 14 to slide in a direction perpendicular to clamping plate 2. Since the bottom surface of sliding plate 14 is flush with the bottom surface of clamping plate 2, sliding plate 14 can smooth out wrinkles on the fabric surface and improve fabric flatness during movement. Reset stage: After flattening is completed, the telescopic end of electric push rod 10 retracts, causing sliding block 11, connecting rod 12, and wedge block 13 to reset. At the same time, the reset spring 18 on the top surface connecting seat 17 of sliding plate 14 releases its elasticity, pulling sliding plate 14 back to its initial position, preparing for the next fabric flattening. Once a single embroidery is completed, the drive motor 7 is started in reverse, the threaded rod 5 rotates in reverse, driving the movable rod 6 and the slide 3 to move in reverse. The connecting rod 4 pulls the clamping plate 2 to rotate upward and open, allowing the operator to remove the embroidered fabric and complete one clamping-embroidery-disassembly cycle.
