Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, and in particular to a feeding mechanism for automated sewing equipment. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on a fabric, allowing one or more layers of fabric to interweave or sew together. Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as products made of leather, plastic, and paper. The stitches produced are neat, beautiful, flat, and strong. Sewing machines are fast and easy to use.

[0003] In existing automated sewing equipment, fabric feeding typically relies on complex mechanical structures. Current technologies often lack an effective mechanism to automatically clamp the fabric to prevent slippage or displacement during transport. In traditional feeding mechanisms of automated sewing equipment, the fabric can slip or shift due to various reasons, such as the smoothness of the fabric surface, the coefficient of friction of different materials, and vibrations during transport. This slippage or displacement leads to inaccurate positioning of the fabric at the bottom of the sewing machine, affecting sewing quality, increasing scrap rates, and reducing production efficiency. Traditional feeding mechanisms often rely on the operator's pre-fixation of the fabric, which not only increases the number of steps but also depends on the operator's skill and attention, easily introducing human error. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a feeding mechanism for automated sewing equipment, aiming to improve the problem that the feeding mechanism for automated sewing equipment in the prior art cannot automatically clamp the fabric and transport it to the lower part of the sewing machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for automated sewing equipment, comprising a worktable, mounting seats fixedly connected to both outer sides of the worktable, limiting rods fixedly connected inside the two mounting seats, and limiting blocks slidably connected to the outer sides of the two limiting rods, a fixed seat fixedly connected to the front of the front mounting seat, a movable seat slidably connected inside the fixed seat, a motor fixedly connected to the bottom of the movable seat, a drive gear fixedly connected to the output end of the motor, a driven gear meshing with the upper part of the drive gear, one end of a movable support rod fixedly connected inside the driven gear, one end of a movable support rod rotatably connected to the other end of the movable support rod rotatably connected to one end of a movable support rod 2, the other end of the movable support rod rotatably connected to the front of the fixed seat, and the limiting blocks fixedly connected to the rear of the movable seat, with pressing components fixedly connected to opposite sides of the two limiting blocks, the pressing components being used to fix the fabric.

[0006] Furthermore, support rods are fixedly connected to both sides of the right side of the workbench, and a fixed frame is fixedly connected to the left side of each of the two support rods. A cylinder is fixedly connected to the front of the fixed frame, and a mounting plate is fixedly connected to the output end of the cylinder. A hydraulic cylinder is fixedly connected to the upper part of the mounting plate, and a pressure roller is fixedly connected to the output end of the hydraulic cylinder.

Electric push rods are fixedly connected to the upper parts of the two movable frames, and pressure plates are fixedly connected to the output ends of the two electric push rods.

[0008] Furthermore, guide rods are fixedly connected to both sides of the upper part of the two pressure plates, and circular plates are fixedly connected to the upper parts of the multiple guide rods.

[0009] Furthermore, all of the guide rods are slidably connected inside the movable frame, and all of the guide rods are fitted with compression springs.

[0010] Furthermore, one end of each of the multiple compression springs is fixedly connected to the upper part of the movable frame, and the other end of each of the multiple compression springs is fixedly connected to the bottom of the circular plate.

[0011] Furthermore, a sewing machine is fixedly connected to the upper part of the workbench, and support frames are fixedly connected to both sides of the bottom of the workbench. The two movable frames are slidably connected to the upper sides of the workbench.

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.

[0024] Reference Figure 1 , Figure 4 and Figure 5This utility model provides an embodiment of a feeding mechanism for an automated sewing equipment, comprising a workbench 1, with mounting seats 4 fixedly connected to both outer sides of the workbench 1. Limiting rods 13 are fixedly connected inside each of the two mounting seats 4, and limiting blocks 12 are slidably connected to the outer sides of each of the two limiting rods 13. A fixed seat 5 is fixedly connected to the front of the front mounting seat 4, and a movable seat 11 is slidably connected inside the fixed seat 5. A motor 6 is fixedly connected to the bottom of the movable seat 11, and a driving gear 7 is fixedly connected to the output end of the motor 6. A driven gear 8 is meshed with the upper part of the driving gear 7. One end of a movable support rod 9 is fixedly connected inside the driven gear 8, and one end of a movable support rod 10 is rotatably connected to the other end of the movable support rod 9. The other end of the movable support rod 10 is rotatably connected to the front of the fixed seat 5. A front limiting block 12 is fixedly connected to the rear of the movable seat 11, and a pressing assembly is fixedly connected to the opposite side of each of the two limiting blocks 12. The clamping assembly is used to fix the fabric. The clamping assembly includes a movable frame 14, an electric push rod 15, and a pressure plate 19. The two movable frames 14 are fixedly connected to the opposite side of the two limit blocks 12. The upper part of the two movable frames 14 is fixedly connected to the electric push rod 15. The output end of the two electric push rods 15 is fixedly connected to the pressure plate 19. The upper sides of the two pressure plates 19 are fixedly connected to the guide rods 16. The upper part of the multiple guide rods 16 is fixedly connected to the circular plate 17. The multiple guide rods 16 are slidably connected inside the movable frame 14. The outer side of the multiple guide rods 16 is fitted with compression springs 18. One end of the multiple compression springs 18 is fixedly connected to the upper part of the movable frame 14, and the other end of the multiple compression springs 18 is fixedly connected to the bottom of the circular plate 17. The upper part of the worktable 1 is fixedly connected to the sewing machine 3. The bottom sides of the worktable 1 are fixedly connected to the support frame 2. The two movable frames 14 are slidably connected to the upper sides of the worktable 1.

[0025] The fabric is laid flat between the two movable frames 14. The two electric push rods 15 are activated, their outputs pushing the pressure plate 19 to move. As the pressure plate 19 moves, the guide rod 16 slides accordingly within the movable frame 14. The downward movement of the guide rod 16 further pulls the circular plate 17 to move, simultaneously applying pressure to the compression spring 18. The guide rod 16 is connected to the pressure plate 19. When the pressure plate 19 moves, the guide rod 16 slides within the movable frame 14, providing guidance. The compression spring 18 is compressed when the circular plate 17 moves, providing cushioning and stabilization. Under the push of the guide rod 16, the pressure plate 19 fixes the fabric in place. Next, the motor 6 is started, its output driving the drive gear 7 to rotate. The drive gear 7 meshes with the driven gear 8. The driven gear 8 rotates, causing the driven gear 8 to rotate. The rotation of the driven gear 8 causes the movable support rod 9 to rotate, and the chain reaction of its rotation causes the movable support rod 10 to rotate as well. The rotation of one end of the movable support rod 10 causes the other end to rotate at the front of the fixed seat 5. Together with the force of the movable support rod 9, the movable seat 11 moves smoothly inside the fixed seat 5. The forward movement of the movable seat 11 causes the limiting block 12 to slide along the outside of the limiting rod 13. The limiting rod 13 is fixed to the equipment and provides a sliding track for the limiting block 12 to ensure the precise movement of the fabric. This, in turn, guides the movable frame 14 to move. The two movable frames 14 work together to guide the fabric to move smoothly on the worktable 1, and finally deliver the fabric precisely to the bottom of the sewing machine 3 for sewing.

[0026] Reference Figures 1-3 Support rods 20 are fixedly connected to both sides of the right side of the workbench 1. Fixing frames 21 are fixedly connected to the left side of the two support rods 20. Cylinders 22 are fixedly connected to the front of the fixing frames 21. Mounting plates 23 are fixedly connected to the output end of cylinders 22. Hydraulic cylinders 25 are fixedly connected to the upper part of mounting plates 23. Pressure rollers 26 are fixedly connected to the output end of hydraulic cylinders 25. Slide rods 24 are fixedly connected to both sides of the inside of the fixing frames 21. Mounting plates 23 are slidably connected to the outside of slide rods 24.

[0027] After the fabric is securely fixed, cylinder 22 is activated, and its output drives mounting plate 23 to reciprocate along slide bar 24. Slide bar 24 provides a stable track for mounting plate 23, enabling it to perform precise reciprocating motion under the action of cylinder 22. At the same time, hydraulic cylinder 25 is also activated, and its output pushes pressure roller 26 downward to press it. Pressure roller 26 rolls back and forth above the fabric, effectively reducing fabric wrinkles and thus optimizing the sewing process.

[0028] Working principle: First, the fabric is placed between two movable frames 14. Two electric push rods 15 are activated. The output ends of the electric push rods 15 push the pressure plate 19 to move. When the pressure plate 19 moves, it causes the guide rod 16 to slide inside the movable frame 14. The guide rod 16 moves downwards, causing the circular plate 17 to move. When the circular plate 17 moves, it squeezes the compression spring 18. Under the action of the guide rod 16, the pressure plate 19 moves downwards to fix the fabric. Next, the motor 6 is activated. The output end of the motor 6 drives the drive gear 7 to rotate. The drive gear 7 drives the meshing driven gear 8 to rotate. The rotation of the driven gear 8 drives the movable support rod 1 9 to rotate. When one end of the movable support rod 1 9 rotates, the other end drives the movable support rod 2 10 to rotate. When one end of the movable support rod 2 10 rotates, the other end rotates at the front of the fixed base 5. Under the combined action of the movable support rod 1 9 and the movable support rod 2 10... The moving seat 11 moves inside the fixed seat 5. When the moving seat 11 moves, it causes the limiting block 12 to slide outside the limiting rod 13. The movement of the limiting block 12 causes the movable frame 14 to move. The two movable frames 14 cause the fabric to move on the upper part of the worktable 1, and transport the fabric to the lower part of the sewing machine 3 for sewing. This prevents the fabric from sliding or shifting during the sewing process, enables more precise control of the fabric transport, and improves the automation of the entire sewing process. After the fabric is fixed, the cylinder 22 is started. The output end of the cylinder 22 drives the mounting plate 23 to move back and forth along the slide rod 24. At the same time, the hydraulic cylinder 25 is started. The output end of the hydraulic cylinder 25 pushes the pressure roller 26 downward. The pressure roller 26 rolls back and forth on the upper part of the fabric, which effectively rolls the fabric, reduces fabric wrinkles, helps optimize the sewing process, and ensures that the fabric remains flat during the feeding process.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
