[0002] Nylon is a type of polyamide fiber, which can be made into long or short fibers. Nylon is the commercial name for polyamide fiber, also known as Nylon. Nylon fiber is the raw material for many kinds of man-made fibers. The emergence of nylon has given textiles a brand-new look. Its synthesis is a major breakthrough in the synthetic fiber industry and also a very important milestone in polymer chemistry.

[0003] Nylon fabric is widely used in textiles, industry, and many other fields. During the production process, it needs to be precisely cut to meet the requirements of different lengths and specifications. Traditional nylon fabric cutting methods usually rely on manual operation or the use of simple mechanical equipment. These methods often rely on manual visual inspection or simple mechanical control, which makes it difficult to guarantee cutting accuracy and often leads to inconsistent cutting lengths, affecting product quality. To address these issues, a cutting device for nylon fabric production is proposed. Utility Model Content

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figure 1-7 As shown, a cutting device for nylon fabric production includes a frame 1. Two mounting plates 2 are fixedly connected to the right side of the frame 1. A nylon fabric roll 3 is disposed between the two mounting plates 2. Mounting plates 4 are fixedly connected to the front and rear sides of the frame 1. A conveying roller 5 is rotatably connected between the two mounting plates 4 at the middle. A driven roller 6 is rotatably connected between the two mounting plates 4 below the conveying roller 5. A first gear 7 is fixedly connected to the front side of the conveying roller 5 through the front mounting plate 4. A second gear 8 is fixedly connected to the front side of the driven roller 6 through the front mounting plate 4. The first gear 7 and the second gear 8 mesh. A first motor 9 for driving the conveying roller 5 to rotate is fixedly installed on the side of the rear mounting plate 4.

[0024] Specifically, a fixing plate 10 is fixedly connected to the lower inner side of each of the two mounting plates 4. A first guide rod 11 is fixedly connected between each of the two fixing plates 10 and the top of the mounting plate 4. A moving block 12 is slidably connected to the surface of the first guide rod 11 on both the front and rear sides. A pressure roller 16 is rotatably connected between the two moving blocks 12. The pressure roller 16 cooperates with the follower roller 15 to appropriately press the fabric, ensuring that the tension of the fabric is uniform during the conveying process and avoiding wrinkles or loosening.

[0025] Specifically, a follower roller 15 is rotatably connected between the two mounting plates 4 below the fixed plate 10. The upper right side of both mounting plates 4 is threaded with a first threaded rod 13. The lower ends of the two first threaded rods 13 are rotatably connected to the top surfaces of the two moving blocks 12 respectively. The top of the two first threaded rods 13 is fixedly connected with a handwheel 14. The follower roller 15 assists in the fabric conveying, reduces frictional resistance, and lowers the risk of fabric damage. The two handwheels 14 can be kept in synchronous rotation by a linkage device (such as a synchronous belt and a synchronous pulley) to ensure that the two ends of the pressing roller 16 are raised and lowered synchronously. This is not shown in the figure, but it is common knowledge that those skilled in the art can understand, and will not be elaborated on here.

[0026] Specifically, a cutting platform 17 is fixedly connected between the two mounting plates 4 on the left side. A groove is provided on the left side of the upper surface of the cutting platform 17. The cutting platform 17 is provided with a groove to facilitate the cutting blade 26 to cut in and to prevent the fabric from slipping.

[0027] Specifically, a connecting plate 18 is fixedly connected above the two mounting plates 4. A cylinder 19 is fixedly installed in the middle of the upper surface of the connecting plate 18. The output end of the cylinder 19 passes through the connecting plate 18 and is fixedly connected to a pressing plate 20. Guide posts 21 are fixedly connected to both the front and rear sides of the upper surface of the pressing plate 20. The guide posts 21 are slidably connected to the connecting plate 18 through guide sleeves. The cooperation between the pressing plate 20 and the guide posts 21 ensures the stability and accuracy of the pressing plate 20's descent.

[0028] Specifically, a second threaded rod 22 is rotatably connected between the two mounting plates 4 on the left side of the clamping plate 20, and a second guide rod 23 is fixedly connected between the two mounting plates 4 on the right side of the second threaded rod 22. A threaded block 24 is threadedly connected to the surface of the second threaded rod 22, and the right side of the threaded block 24 is slidably connected to the second guide rod 23. A second motor for driving the rotation of the second threaded rod 22 is fixedly installed on the side of the rear mounting plate 4. The cooperation of the second threaded rod 22 and the second guide rod 23 enables the threaded block 24 to move laterally, thereby driving the cutting blade 26 to perform lateral cutting.

[0029] Specifically, an electric push rod 25 is fixedly connected to the bottom of the threaded block 24, and a cutting blade 26 is fixedly installed at the output end of the electric push rod 25. The design of the electric push rod 25 enables the cutting blade 26 to descend quickly and accurately and cut into the fabric, achieving fast and efficient cutting.

[0030] Working principle: The nylon fabric roll 3 is installed between the mounting plates 2 on the right side of the frame 1. The fabric end is pulled out and passed between the pressure roller 16 and the follower roller 15, and between the conveying rubber roller 5 and the driven rubber roller 6, and placed above the cutting platform 17. According to the thickness of the nylon fabric, the handwheel 14 is rotated to drive the first threaded rod 13 to rotate. The moving block 12 slides up and down along the first guide rod 11 to adjust the distance between the pressure roller 16 and the conveying rubber roller 5, ensuring that the fabric is appropriately compressed and can be conveyed smoothly. The follower roller 15 supports the bottom of the fabric and works with the pressure roller 16 to maintain uniform fabric tension and avoid wrinkles or looseness during the conveying process. The first motor 9 is started, and its output shaft drives the conveying rubber roller 5. The first motor 9 rotates, and through the meshing of the first gear 7 and the second gear 8, the driven rubber roller 6 rotates synchronously in the opposite direction, clamping and conveying the nylon fabric at a uniform speed. When the fabric is conveyed to a suitable length, the first motor 9 stops running, and the cylinder 19 is started. Its output end pushes the pressure plate 20 down along the guide post 21 to press the fabric onto the cutting platform 17 to prevent displacement during cutting. The electric push rod 25 drives the cutting blade 26 to cut downward into the fabric, and a clean cut is achieved by using the groove of the cutting platform 17. The second motor drives the second threaded rod 22 to rotate, and the threaded block 24 moves laterally along the second guide rod 23, thereby causing the cutting blade 26 to move laterally and cut the nylon fabric.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
