[0002] In the manufacturing sectors of textiles, apparel, and home furnishings, overlock machines are crucial equipment for treating fabric edges and preventing fraying. The performance of their material transmission mechanisms directly impacts production efficiency and processing quality. Traditional overlock machines often employ fixed material transmission systems, which, when faced with fabrics of varying thicknesses and materials or diverse overlocking process requirements, exhibit problems such as inconvenient adjustment and poor adaptability, making it difficult to meet the demands of modern manufacturing for flexible production and efficient switching.

[0031] Example 1
[0032] Please see Figures 1-4This utility model provides a technical solution: a material transmission mechanism for an easily adjustable overlock machine, comprising a support frame 1, a worktable 2, an overlock machine body 3, a smooth plate 4, a guide strip 5, a through hole 6, a threaded groove 7, a positioning bolt 8, an adjusting threaded rod 9, a slider 10, a guide rod 11, a connecting block 12, a connecting piece 13, a vertical block 14, a reinforcing rod 15, a mounting frame 16, an electric conveyor belt 17, an anti-slip rack 18, a connecting assembly 19, a first hinge assembly 20, a cylinder 21, a telescopic rod 22, a mounting plate 23, and a second hinge assembly 24. The worktable 2 is mounted above the support frame 1, and the overlock machine is mounted above the worktable 2. The machine consists of a main body 3 and a smooth plate 4. A guide strip 5 is installed on the front side of the main body 3, passing through the smooth plate 4. Through holes 6 are evenly spaced on the guide strip 5. Threaded grooves 7 are evenly spaced on the upper surface of the worktable 2, corresponding to the through holes 6. Positioning bolts 8 pass through the through holes 6 and are threadedly connected to the threaded grooves 7. To adjust the position of the smooth plate 4 and the electric conveyor belt 17, loosen the positioning bolts 8, move the smooth plate 4 along the guide strip 5 to the desired position, aligning the threaded grooves 7 with the through holes 6. Then, connect the positioning bolts 8 through the through holes 6 to the threaded grooves 7. The structure is simple and easy to operate. A shaft passes above the smooth plate 4. The support is equipped with an adjusting threaded rod 9, and a slider 10 is mounted on the adjusting threaded rod 9. A guide rod 11 passes through the slider 10 and is connected to the smooth plate 4. The guide rod 11 and the slider 10 are slidably connected. By rotating the adjusting threaded rod 9 according to the material thickness, the slider 10 is driven to slide up and down along the guide rod 11. This drives the mounting frame 16 to move up and down through the connecting block 12, connecting piece 13, and vertical block 14, thereby adjusting the height of the electric conveyor belt 17 between the mounting frames 16. This allows the electric conveyor belt 17 to convey materials of different thicknesses. A connecting block 12 is installed below the slider 10, and a guide rod 11 is mounted on the front side of the connecting block 12. There is a connecting piece 13, and a vertical block 14 is installed on the front side of the connecting piece 13. A mounting frame 16 is installed on the front side of the vertical block 14 via a reinforcing rod 15. The mounting frame 16 and the reinforcing rod 15 are connected by a bearing assembly. The mounting frame 16 and the reinforcing rod 15 are rotatably connected. There are two mounting frames 16. An electric roller is installed between the mounting frames 16. The electric roller is located inside the electric conveyor belt 17. When the electric roller is driven, it drives the electric conveyor belt 17 to rotate. The electric conveyor belt 17 is used to transport the material below. An electric conveyor belt 17 is installed between the mounting frames 16. The surface of the electric conveyor belt 17 is provided with anti-slip toothed strips 18.
[0033] A connecting assembly 19 is installed on the right side of the slider 10. Two connecting assemblies 19 are provided, and a first hinge assembly 20 is installed between them. The first hinge assembly 20 is connected to a cylinder 21. Activating the cylinder 21 causes the telescopic rod 22 to retract. The telescopic rod 22, through the second hinge assembly 24, causes the mounting frame 16 to rotate around the reinforcing rod 15, causing the right end of the electric conveyor belt 17 to tilt upwards. After material is placed in, the telescopic rod 22 extends, causing the electric conveyor belt 17 to return to its original position and transport the material. 7. The anti-slip toothed strip 18 on the surface prevents the material from slipping during conveying. A cylinder 21 is installed on the connecting assembly 19. A telescopic rod 22 is installed below the cylinder 21. Mounting plates 23 are installed above the mounting frame 16. A second hinge assembly 24 is installed between the mounting plates 23. The second hinge assembly 24 is connected to the telescopic rod 22. A rotating sleeve is installed at the lower end of the telescopic rod 22. The rotating sleeve is rotatably connected to the second hinge assembly 24, so that the telescopic rod 22 can rotate along the second hinge assembly 24 when subjected to force.
[0034] Example 2
[0035] Please see Figure 5 This utility model provides a technical solution: a material transmission mechanism for an easily adjustable overlock machine, including a threaded frame 25 and a limiting bolt 26. The difference between this embodiment and Embodiment 1 is that:
[0036] Threaded brackets 25 are threaded through both the left and right sides of the smooth plate 4. The threaded brackets 25 are connected to the worktable 2. Limiting bolts 26 are installed on both the left and right sides of the threaded brackets 25. When it is necessary to adjust the position of the smooth plate 4 and the electric conveyor belt 17, rotate the limiting bolts 26 to move them away from the smooth plate 4. Then move the smooth plate 4 to the required position and rotate the limiting bolts 26 to clamp the smooth plate 4, thereby achieving stable limiting of the smooth plate 4.
[0037] Working principle: When using the easily adjustable material transmission mechanism of the overlock machine, firstly, start the cylinder 21 to drive the telescopic rod 22 to retract. The telescopic rod 22 drives the mounting frame 16 to rotate around the reinforcing rod 15 through the second hinge assembly 24, causing the right end of the electric conveyor belt 17 to tilt up. After the material is placed in, the telescopic rod 22 extends to reset the electric conveyor belt 17 and abut against the material to realize the conveying of the material. The anti-slip toothed strip 18 on the surface of the electric conveyor belt 17 prevents the material from slipping during conveying. The right side of the material that needs to be edged is located below the overlock machine body 3. The overlock machine body 3 edge-locks the material.
[0038] The adjusting threaded rod 9 is rotated according to the material thickness, driving the slider 10 to slide up and down along the guide rod 11. This, in turn, causes the mounting frame 16 to move up and down via the connecting block 12, connecting piece 13, and vertical block 14, thereby adjusting the height of the electric conveyor belt 17 between the mounting frames 16. This allows the electric conveyor belt 17 to convey materials of different thicknesses, thus completing a series of tasks. Content not described in detail in this specification constitutes prior art known to those skilled in the art.
