Description

Technical Field

[0001] This utility model relates to the field of thermal traction setting machine technology, and in particular to a high-strength synthetic fiber multi-stage stretching and setting device. Background Technology

[0002] Stretch setting of synthetic fibers is a common fiber post-processing technique. By treating fibers under specific temperature and tension conditions, the appearance of the fibers can be improved, making them straighter and more regular, reducing wrinkling and deformation. At the same time, it can improve the dimensional stability of the fibers, making the fabrics less prone to shrinkage during subsequent use and washing. It can also optimize the mechanical properties of the fibers, making the strength and elasticity of the fibers more in line with application requirements. This process is widely used in the production of various synthetic fiber products such as clothing and home textiles, providing important support for the practical application and quality improvement of synthetic fiber materials.

[0003] In the production process of synthetic fiber stretching and setting, the precise control of stretching tension directly affects the final quality and performance of the product. As the market demands for synthetic fiber materials in terms of strength, elasticity, and uniformity continue to increase, the requirements for adapting stretching tension to synthetic fibers with different properties are becoming more diverse. Traditional stretching devices often have fixed tension adjustment modes or limited adjustment ranges, making it difficult to flexibly adjust the tension according to fiber characteristics and production processes. This results in the inability to achieve precise control of stretching tension, which can easily lead to uneven fiber stretching and poor quality consistency during the production process. Therefore, a high-strength synthetic fiber multi-stage stretching and setting device is needed. Utility Model Content

[0016] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a high-strength synthetic fiber multi-stage stretching and shaping device, wherein: The stretching worktable 1 serves as the installation foundation and load-bearing body of the entire device. It is made of high-strength alloy material and has good structural stability and load-bearing performance. Its bottom is tightly fitted with the shock-absorbing base 2.

[0021] The shock-absorbing base 2 is made of elastic damping material. It absorbs the vibration generated during the operation of the device through its own buffering and shock-absorbing characteristics, reduces the impact of vibration on the fitting accuracy of each component and the fiber stretching and shaping effect, and ensures the overall stable operation of the device.

[0022] The top of the stretching worktable 1 is fixedly connected to the first bracket A3. The first bracket A3 provides stable installation support for the guide roller 4. The guide roller 4 is rotatably connected to the surface of the first bracket A3 through a rotating shaft. The guide groove 5 opened on its surface is adapted to the synthetic fiber.

[0023] The guide groove 5 can accurately guide and limit the synthetic fiber, preventing the fiber from deviating or tangling during transmission, and ensuring that the fiber is stably transmitted along the preset path to the subsequent stretching and shaping structure.

[0024] The top of the stretching worktable 1 is also fixedly connected to the third bracket C7, which provides sliding support for the lifting bracket 9. The lifting bracket 9 has a concave cross-section, and its bottom is fixedly connected to the output end of the electric push rod 8. The electric push rod 8 is fixed to the top of the stretching worktable 1.

[0025] The electric push rod 8 can drive the lifting bracket 9 to slide up and down along the guide direction of the third bracket C7, so as to realize the flexible adjustment of the height of the lifting bracket 9, thereby adapting to the stretching and shaping requirements of synthetic fibers of different specifications and improving the versatility of the device.

[0026] The top of the lifting bracket 9 is connected to the detachable top frame 13 by a locking block 15 and a locking slot 14. The locking block 15 is fixed to the bottom of the detachable top frame 13, and the locking slot 14 is opened on the top of the lifting bracket 9 and is precisely matched with the locking block 15, so as to realize the quick installation and removal of the detachable top frame 13.

[0027] This snap-fit ​​connection method facilitates the subsequent maintenance and replacement of components such as the heating element 10 and the auxiliary fastening structure 16, reducing equipment maintenance costs and improving maintenance efficiency.

[0028] A heating component 10 is fixedly installed on the top of the lifting bracket 9. The heating component 10 is made of a material with high temperature resistance and excellent thermal conductivity. Its top is fixedly connected to multiple heating supports 11 at equal distances. The heating supports 11 provide a mounting carrier for the heating traction wheel 12.

[0029] The heating traction wheel 12 is rotatably connected to the surface of the heating support 11 via a rotating shaft. The heat generated by the heating component 10 is transferred to the heating traction wheel 12 through the heating support 11, so that the heating traction wheel 12 maintains a stable working temperature and provides heat support for fiber heating and shaping.

[0030] The top of the detachable top frame 13 is fixedly connected to the bracket 17, the bottom of the bracket 17 is fixedly connected to the spring 18, the other end of the spring 18 is fixedly connected to the auxiliary fastening structure 16, the auxiliary fastening structure 16 is slidably connected to the surface of the detachable top frame 13, and its bottom is in contact with the heating traction wheel 12.

[0031] The spring 18 continuously provides downward pressure to the auxiliary bonding structure 16 through its own elastic force, so that the auxiliary bonding structure 16 and the heating traction wheel 12 are closely matched, pressing the synthetic fiber onto the surface of the heating traction wheel 12 to ensure the heating and stretching effect.

[0032] The auxiliary bonding structure 16 can be a limiting block with an arc-shaped bottom or a limiting block with a roller at the bottom. The arc-shaped bottom design can increase the contact area with the fiber, and the roller design can reduce friction damage with the fiber, adapting to different working conditions.

[0033] The top of the stretching worktable 1 is also fixedly connected to the second bracket B6. The second bracket B6 provides mounting support for components such as the motor 19 and the eccentric wheel 20. The motor 19 is fixed to the surface of the second bracket B6, and its output end is fixedly connected to the eccentric wheel 20. The eccentric wheel 20 is rotatably connected to the second bracket B6.

[0034] The opposing surfaces of the two eccentric wheels 20 are rotatably connected to the rotating rod 21. The rotating rod 21 is fixedly sleeved with multiple tension traction wheels 22. When the motor 19 runs, it drives the eccentric wheels 20 to rotate. The rotational motion of the eccentric wheels 20 is converted into the reciprocating motion of the tension traction wheels 22 through the rotating rod 21.

[0035] Working principle: The shock-absorbing base 2 provides stable support for the stretching worktable 1. The guide roller 4 on the first bracket A3 guides and limits the synthetic fiber through the guide groove 5. The electric push rod 8 on the third bracket C7 drives the lifting bracket 9 to adjust the height. The lifting bracket 9 cooperates with the card slot 14 and the card block 15 to realize the installation and fixation of the detachable top frame 13. The heating component 10 provides heat to the heating traction wheel 12 through the heating support 11. The spring 18 on the bracket 17 pushes the auxiliary pressing structure 16 to cooperate with the heating traction wheel 12 to press the fiber. The motor 19 on the second bracket B6 drives the eccentric wheel 20 to rotate. The eccentric wheel 20 drives the stretching traction wheel 22 to move through the rotating rod 21. Adjusting the rotation angle of the eccentric wheel 20 can flexibly change the fiber stretching tension. Through the cooperation of the stretching traction wheel 22 and the heating traction wheel 12, the multi-stage stretching and heating shaping of the synthetic fiber is realized.

[0036] Example 1: (Reference) Figure 3 ) The auxiliary clamping structure 16 adopts a limiting block with an arc-shaped bottom surface. When used in conjunction with the heating traction wheel 12, the arc-shaped bottom surface can form a good fit with the outer surface of the heating traction wheel 12, increasing the contact area with the synthetic fiber. This makes the clamping force on the fiber more uniform during the heating and traction process, avoiding excessive local pressure that could damage the fiber. At the same time, the stable clamping effect ensures that the fiber and the heating traction wheel 12 are in full contact, improving the uniformity of heating and setting, reducing the problem of poor setting effect due to poor contact. It is suitable for stretching and setting operations of synthetic fibers with high requirements for surface flatness, ensuring the consistency of product quality.

[0037] Example 2: (Reference) Figure 4 ) The auxiliary bonding structure 16 adopts a limiting block with a roller at the bottom. When this structure is used in conjunction with the heated traction wheel 12 to press the synthetic fiber, the roller can roll synchronously with the rotation of the heated traction wheel 12, which greatly reduces the frictional resistance with the fiber surface and reduces the probability of scratches, fuzzing and other damage to the fiber surface. It is especially suitable for synthetic fibers with high requirements for surface smoothness or fragile materials. At the same time, the rolling cooperation can reduce the resistance in the fiber transmission process, ensure smooth fiber transmission, avoid uneven fiber stretching due to excessive friction, and further improve the stability of the stretching and shaping process and the product qualification rate.

[0038] Example 3: (Reference) Figure 1-4 ) When the auxiliary bonding structure 16 is a bottom arc-shaped limiting block, it is suitable for scenarios that require large-area uniform heating and shaping, and have strict requirements for the flatness of the product surface and the consistency of shaping, such as the production of high-strength synthetic fiber fabrics and industrial synthetic fiber tapes. When the auxiliary bonding structure 16 is a bottom roller limiting block, it is suitable for scenarios with softer materials, easily damaged surfaces, or high requirements for smooth transmission, such as the stretching and shaping of ultrafine synthetic fibers and functional synthetic fiber filaments. The two structures can be flexibly selected according to production needs to meet the processing requirements of synthetic fibers with different characteristics.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
