[0002] As people's living standards improve, they are paying more attention to their clothing, and all kinds of clothing have emerged. Before making clothing, a whole piece of cloth needs to be laid out and cut, so a highly stable automatic cutting machine for clothing processing is needed to process the cloth.
[0003] Traditionally, fabric tension adjustment is achieved using multiple fabric-pulling rollers. However, because the tension on different rollers is uneven during fabric pulling, the rollers are prone to shifting and tearing the fabric, thus affecting cutting efficiency and quality. To address this, we propose a fabric-pulling device for cutting machines. Utility Model Content

An inclined plate 15 is connected to the upper end of the side of the bracket 17 near the first transport rollers 32. A hopper 19 for placing fabric rollers is connected to the top of the inclined plate 15, and an opening 20 is provided at the bottom of the hopper 19. When placing fabric, the free end of the fabric passes through the opening 20 and moves into the bracket 17. The opening 20 can guide the movement of the fabric.
[0023] like Figure 2 , 3As shown, a second guide roller 26 is provided at the lower end of one side of the first transport roller 32. A first through groove 22 is opened on the bracket 17. Both ends of the first through groove 22 are fastened with second supports 13. A first connecting seat 2 is provided between the two second supports 13. A first electric push rod 4 is connected between the first connecting seat 2 and one of the second supports 13. A rotating shaft passing through the first through groove 22 is fastened to the end of the second guide roller 26. The rotating shaft is rotatably connected to the first connecting seat 2. Under the push of the first electric push rod 4, the second guide roller 26 can be driven to move up and down and slide, which can adjust the tension of the fabric and avoid damage to the fabric due to excessive tension. In actual use, a pressure sensor is set on the surface of the second guide roller 26, which is conducive to real-time pressure monitoring. At the same time, in order to improve the stability of the second guide roller 26's lifting and lowering, multiple first vertical rods 3 are fastened between the two second supports 13. The first vertical rods 3 are set through the first connecting seat 2.
[0024] like Figure 2 , 3 As shown, a first guide roller 23 is symmetrically arranged above the second guide roller 26 and slidably connected to the bracket 17. A second through groove 24 is provided on the bracket 17. Both ends of the second through groove 24 are connected to a third support 21. A second vertical rod 12 is vertically connected between the two third supports 21. A second connecting seat 10 is provided through the second vertical rod 12. A return spring 11 coaxial with the second vertical rod 12 is tightly fastened between the second connecting seat 10 and the third support 21. The ends of the first guide roller 23 are connected to a rotating shaft that passes through the second through groove 24 and rotatably connects the rotating shaft to the second connecting seat 10. When the fabric passes through the first guide roller 23, under the action of tension, the first guide roller 23 can be driven to slide downward and push the second connecting seat 10 to slide on the second vertical rod 12. Under the elastic force of the return spring 11, the tension can be effectively buffered and the tension on the two first guide rollers 23 can be made uniform, which further protects the fabric.
[0025] In summary, when using the fabric pulling device of this cutting machine, if... Figure 2 , 3 As shown, a cutting mechanism connected to a bracket 17 is provided below the side of the second guide roller 26 away from the first transport roller 32. The cutting mechanism includes side plates 33 symmetrically arranged in the bracket 17. The lower ends of the two side plates 33 are connected to a guide plate 28, and a linear module 27 connected to the side plates 33 is provided above the guide plate 28. A motor housing 25 is slidably connected to the bottom of the linear module 27. A third motor 31 is tightly fitted inside the motor housing 25. A cutting blade 30 is tightly fitted on the output end of the third motor 31. The bottom of the cutting blade 30 is clearance-fitted with the top of the guide plate 28. Driven by the third motor 31 and the linear module 27, the cutting blade 30, which moves linearly and rotates synchronously, cuts the fabric located on the top of the guide plate 28.
[0026] Meanwhile, two second transport rollers 34 are connected to the side plate 33 via a connecting shaft 18 on one side of the guide plate 28. A third through groove 29 is provided on the bracket 17. The mounting frame 9 is slidably connected to the outside of the third through groove 29. The end of the connecting shaft 18 passes through the third through groove 29 and is connected to the mounting frame 9. Gears 8 are coaxially connected to one end of the connecting shaft 18. The two gears 8 are meshed and connected. A second motor 16 is fastened to the end of one of the connecting shafts 18. A first support 6 is fastened to the outer wall of the bracket 17. A second electric push rod 7 is fastened between the first support 6 and the mounting frame 9. By pushing the second electric push rod 7, the guide plate 28, the second transport rollers 34 and the cutting blade 30 can be driven to move up and down and slide. During the fabric pulling process, as the thickness of the fabric increases, the distance between the guide plate 28 and the top of the processing table 1 can be adjusted, which improves the practicality of the device. In order to ensure the stability of the sliding, multiple guide rods 5 that pass through the first support 6 are fastened to the mounting frame 9.
