[0002] Composite fibers are fibers composed of two or more immiscible polymers, possessing properties such as three-dimensional crimp, high bulkiness, and coverage, and are typically used for bonding or traction.

[0003] Chinese patent document CN219637441U discloses a composite fiber multi-thread end stretching and traction device. Addressing existing problems, the following solution is proposed: It includes a base plate, with upright plates fixedly installed on both sides of the top of the base plate. A common shaft is rotatably mounted between the two upright plates. A motor is fixedly installed at one end of the shaft and is also fixedly mounted on either upright plate. A moving plate is slidably mounted on either upright plate, and a short column is rotatably mounted on one side of the moving plate. Traction rollers are fixedly sleeved on both the short column and the shaft. A curved rod is fixedly installed on the top side of the moving plate, and a handle is fixedly sleeved at the top of the curved rod. This invention overcomes the shortcomings of existing technologies, allowing for the stretching and traction of composite fiber threads of different thicknesses through adjustment, while also preventing tangling between the threads, thus meeting people's needs.

[0004] After investigation and analysis, the patent has the following drawbacks in actual use:

[0005] The device can accommodate composite fiber ends of different diameters, but its adjustment range and applicable scenarios may still be limited, and it cannot fully meet all production needs. In addition, the device uses multiple components to clamp composite fiber ends of different diameters, and this complex structure increases the manufacturing cost and maintenance difficulty of the equipment.

[0006] In summary, this application proposes a composite fiber multi-thread tensioning and traction device to solve the aforementioned problems. Utility Model Content

At the same time, the device uses multiple components to clamp composite fiber threads of different diameters, and this complex structure increases the manufacturing cost and maintenance difficulty of the equipment.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a composite fiber multi-thread head stretching and traction device, comprising:

[0013] Preferably, the front side of the fixed frame is fixedly installed to the rear side of the U-shaped plate, which facilitates the support and fixation of the fixed frame and makes the sliding of the movable plate more stable.

[0014] Preferably, a pull rod is fixedly installed on the top of the movable plate, which facilitates the pulling of the movable plate.

[0015] Preferably, the lower traction roller and the upper traction roller are on the same center line, which facilitates the clamping and fixing of the composite fiber thread ends.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This composite fiber multi-thread stretching and traction device utilizes a combination of a movable plate, upper traction roller, fixed frame, column, sliding block, and springs. The elastic design of the springs allows the upper traction roller to automatically adjust the clamping force according to the thickness of the composite fiber threads, thus accommodating threads of different sizes and ensuring stable clamping. The springs' cushioning effect reduces vibration and impact during traction, ensuring a smooth process and improving product quality. The automatic adjustment function of the springs reduces the need for manual intervention, simplifies the operation process, and lowers labor intensity. Simultaneously, the cooperation of the upper and lower traction rollers effectively prevents tangling of multiple threads during stretching, improving production efficiency. This design makes the device suitable for the production of various composite fibers, improving the equipment's versatility and applicability. Attached Figure Description

[0024] Please see Figure 1-3This utility model provides a technical solution: a composite fiber multi-thread stretching and traction device, including a fixed frame 1 and an adjusting component. U-shaped plates 2 are fixedly installed on the inner walls of both sides of the fixed frame 1. The adjusting component is set on the U-shaped plates 2. The adjusting component includes a movable plate 6, an upper traction roller 7, a fixed frame 8, a column 9 and a sliding block 10. Fixed frames 8 are provided on both sides of the movable plate 6. Columns 9 are fixedly installed on the top and bottom of the inner side of the fixed frame 8. Sliding blocks 10 are slidably installed on the columns 9. One side of the sliding block 10 is fixedly installed on one side of the movable plate 6. The upper traction roller 7 is rotatably installed on the inner walls of both sides of the movable plate 6.

[0025] Furthermore, a rotating column 3 is rotatably installed on the inner wall of one side of the fixed frame 1, and multiple sets of lower traction rollers 4 are fixedly installed on the outer wall of the rotating column 3. A motor 5 is fixedly installed on one side of the fixed frame 1, and the other end of the rotating column 3 passes through the fixed frame 1 and is fixedly installed with the output shaft of the motor 5, which plays a role in stretching and pulling the composite fiber thread end.

[0026] Furthermore, two sets of springs 11 are fitted onto the column 9, located at the top and bottom of the sliding block 10. One end of one set of springs 11 is fixedly installed to the top of the sliding block 10, and the other end of the other set of springs 11 is fixedly installed to the top inner side of the fixed frame 8. One end of the other set of springs 11 is fixedly installed to the bottom of the sliding block 10, and the other end of the other set of springs 11 is fixedly installed to the bottom inner side of the fixed frame 8.

The upper traction roller 7 on plate 6 clamps and fixes the composite fiber thread end on the lower traction roller 4. The elastic design of spring 11 allows the upper traction roller 7 to automatically adjust the clamping force according to the thickness of the composite fiber thread end, thereby adapting to thread ends of different sizes, ensuring a stable clamping, and the buffering effect of spring 11 can reduce vibration and impact during the traction process, ensuring a smooth traction process and improving product quality. The automatic adjustment function of spring 11 reduces the need for manual intervention, simplifies the operation process, and reduces labor intensity. At the same time, through the cooperation of the upper and lower traction rollers, it can effectively prevent multiple thread ends from tangling during the stretching process, improving production efficiency. This design makes the device applicable to the production of various composite fibers, improving the versatility and applicability of the equipment.

[0027] Furthermore, the front side of the fixed frame 8 is fixedly installed on the rear side of the U-shaped plate 2, which facilitates the support and fixation of the fixed frame 8, making the sliding of the movable plate 6 more stable.

[0028] Furthermore, a pull rod 12 is fixedly installed on the top of the movable plate 6, which facilitates the pulling of the movable plate 6.

[0029] Secondly, the lower traction roller 4 and the upper traction roller 7 are on the same center line, which makes it easy to clamp and fix the composite fiber thread ends.

[0030] Working principle: When in use, first hold the pull rod 12 and pull it upward, so that the movable plate 6 drives the sliding block 10 to move upward and compress the spring 11. Place the composite fiber thread to be pulled on the lower traction roller 4. Release the pull rod 12. The reaction force of the spring 11 drives the sliding block 10 to slide on the column 9, so that the sliding block 10 drives the upper traction roller 7 on the movable plate 6 to clamp and fix the composite fiber thread on the lower traction roller 4. Start the motor 5, and drive the lower traction roller 4 on the rotating column 3 to rotate, thereby driving the composite fiber thread on the upper and lower traction rollers to perform stretching and pulling work.
