However, in the drafting process of high-shrinkage polyester wool-like yarn, the yarn needs to be drafted multiple times, requiring multiple sets of drafting rollers to be used in coordination. The yarn needs to pass through multiple sets of drafting rollers in an S-shape at once, and multiple sets of yarn need to be drafted simultaneously each time, resulting in a slow feeding speed and low feeding convenience. Therefore, it is necessary to invent a high-shrinkage polyester wool-like yarn drafting device to solve the above problems. Utility Model Content

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 6The high-shrinkage polyester wool-like yarn drawing device shown includes a mounting plate 1. Multiple sets of first flexible rollers 11 are rotatably connected to the surface of the mounting plate 1. Positioning grooves 12 are provided on the surface of the mounting plate 1 between two sets of first flexible rollers 11. A lifting assembly is installed on the rear side of the positioning grooves 12. The lifting assembly includes a lifting frame 2, a linear guide rail 21, a lifting screw 22, a lifting plate 23, a mounting base 24, a linear slide plate 25, a housing 3, an electric motor 31, a transmission gear 32, a first toothed belt 33, a bidirectional hydraulic cylinder 34, a locking block 35, and a second toothed belt 36. A second flexible roller 4 is fixedly connected to the front side of the mounting base 24. Both the first flexible rollers 11 and the second flexible roller 4 are metal rollers with a silicone pad layer covering the surface. Multiple sets of grooves are provided on the surface of the silicone pad layer.

[0027] In this process, the yarn is passed through multiple sets of first flexible rollers 11 and second flexible rollers 4 in an S-shape, and the first flexible rollers 11 and second flexible rollers 4 work together to stretch the yarn.

[0028] During the feeding process, the electric motor 31, transmission gear 32, first toothed belt 33, second toothed belt 36 and lifting screw 22 work together to drive the lifting plate 23 to rise and fall, thereby adjusting the height of the second flexible roller 4 to the lower side of the first flexible roller 11. At this time, the yarn only needs to pass through the multiple sets of first flexible rollers 11 and second flexible rollers 4 in a straight line, which makes it easy to get multiple sets of yarn into different grooves inside the second flexible roller 4. When the second flexible roller 4 rises, it cooperates with the first flexible roller 11 to automatically adjust the yarn into an S-shape and get the yarn into the groove on the surface of the first flexible roller 11, effectively improving the convenience of feeding.

[0029] As a preferred embodiment, a drive component 5 is installed on the rear side of both the mounting plate 1 and the lifting plate 23. The drive component 5 includes a reducer 51 and a motor 52. The output end of the reducer 51 is fixedly connected to the rear end of the mounting base 24 and the first flexible roller 11, and the output end of the motor 52 is fixedly connected to the input end of the reducer 51.

[0030] In addition, during the yarn drafting process, the motor 52 and the reducer 51 work together to drive multiple sets of first flexible rollers 11 and second flexible rollers 4 to rotate, thereby driving the yarn to move and drafting the yarn. The speed of the multiple sets of first flexible rollers 11 and second flexible rollers 4 can be adjusted individually through the drive unit 5.

[0031] See Figures 3 to 6The lifting frame 2 is fixedly connected to the rear surface of the mounting plate 1. Linear guide rails 21 are fixedly connected to the inner walls of both sides of the lifting frame 2. Linear sliding plates 25 are fixedly connected to both ends of the lifting plate 23. The linear sliding plates 25 are slidably connected to the linear guide rails 21. The mounting base 24 is rotatably connected to the surface of the lifting plate 23. The front end of the mounting base 24 is slidably connected to the positioning groove 12. The lifting screw 22 is rotatably connected to the inner side of the linear guide rail 21. The linear guide rail 21 is internally threadedly connected to the linear sliding plate 25. Transmission gears 32 are provided on both the left and right sides of the upper end of the lifting frame 2. The upper end of rod 22 passes through the top wall of lifting frame 2 and is fixedly connected to the transmission gear 32 on the same side. The first toothed belt 33 is meshed with the two sets of transmission gears 32 at the upper end of lifting frame 2. The second toothed belt 36 is meshed with the two sets of transmission gears 32 that are close to each other between the two sets of lifting frames 2. The equipment housing 3 is located outside the transmission gear 32, the first toothed belt 33 and the second toothed belt 36. The lower end of the equipment housing 3 is fixedly connected to the upper end of lifting frame 2. The electric motor 31 is fixedly installed at the upper end of the rightmost equipment housing 3. The electric motor 31 is fixedly connected to the upper end of the rightmost transmission gear 32.

[0032] Specifically, during the height adjustment of the second flexible roller 4, the electric motor 31 is started. The output end of the electric motor 31 drives the rightmost transmission gear 32 to rotate. With the cooperation of the first toothed belt 33, it drives the two sets of transmission gears 32 in the same lifting frame 2 to rotate synchronously. At the same time, with the cooperation of the second toothed belt 36, it drives the transmission gears 32 in multiple sets of lifting frames 2 to rotate synchronously, thereby driving multiple sets of lifting screws 22 to rotate synchronously. The two sets of lifting screws 22 on the inner side of the same lifting frame 2 cooperate with the linear slide plate 25 to drive the lifting plate 23 on the inner side of the lifting frame 2 to rise and fall, thereby adjusting the height of the lifting plate 23. The lifting plate 23 adjusts the height of the second flexible roller 4 through the mounting base 24.

[0033] As a preferred embodiment, the bidirectional hydraulic cylinder 34 is fixedly installed at the middle position of the upper end of the lifting frame 2, and locking blocks 35 are fixedly connected to the outer ends of the piston rods on both sides of the bidirectional hydraulic cylinder 34.

[0034] In addition, when the lifting plate 23 is adjusted to the upper end of the assembly, the bidirectional hydraulic cylinder 34 is activated. The bidirectional hydraulic cylinder 34 pushes out the piston rods on both sides simultaneously, thereby abutting the locking block 35 against the sides of the transmission gears 32 on both sides, locking and fixing the transmission gears 32, and improving the stability of the second flexible roller 4 during the stretching process.

[0035] The working principle of this utility model is as follows: The height of the second flexible roller 4 is adjusted by the lifting component. During the feeding process, the second flexible roller 4 is adjusted to the lower side of the first flexible roller 11. At this time, multiple sets of yarns can be directly passed between the first flexible roller 11 and the second flexible roller 4 to complete the feeding. Then, the lifting component is used to lift the second flexible roller 4 upward, so that the yarn forms an S-shape between the first flexible roller 11 and the second flexible roller 4. The driving component 5 drives the first flexible roller 11 and the second flexible roller 4 to rotate, which can pull the yarn, effectively improving the convenience and speed of feeding, and thus improving the processing efficiency of the yarn. At the same time, since both the first flexible roller 11 and the second flexible roller 4 are metal rollers with silicone pads on their surfaces, the silicone pads on the surface of the flexible rollers have a certain elasticity, which can provide a more uniform pressure distribution when in contact with the yarn, reducing damage to the yarn. At the same time, it increases the friction of the surface of the flexible rollers, which can better hold the yarn and prevent slippage.

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 preferred examples and are not intended to limit the utility model.
