Description

Technical Field

[0001] This utility model belongs to the field of twisting technology, specifically relating to a twisting device for special fibers. Background Technology

[0002] Specialty fibers are a class of chemical fibers with special physical and chemical structures and functions, encompassing categories such as corrosion resistance, high temperature resistance, flame resistance, high strength, and high modulus (e.g., polytetrafluoroethylene fiber, carbon fiber, etc.). Twisting, by imparting a twist angle to the fiber, can significantly improve its mechanical properties and structural stability, and is a key step in the processing of specialty fibers.

[0003] Traditional twisting devices typically employ a single rotating mechanism to simultaneously twist multiple fibers. However, due to differences in material properties (such as surface friction coefficient and stiffness), specialty fibers are prone to uneven twist distribution during synchronous twisting. Specifically, this manifests as twist differences between different fibers: the material characteristics cause uneven stress on the fibers during twisting, affecting product quality. Therefore, a twisting device specifically designed for specialty fibers is needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a twisting device for special fibers to solve the problems mentioned in the background art.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figures 1 to 3This utility model provides a technical solution: a twisting device for special fibers, including a base 1, a twisting frame 2 and a rotating frame 3 mounted on the upper side of the base 1, a twisting cylinder 7 rotatably mounted on the upper end of the twisting frame 2, the twisting cylinder 7 having a twisting thread 18 inside, a rotating disk 5 rotatably mounted on the upper end of the rotating frame 3, a rotating motor 4 fixedly mounted on one side of the rotating frame 3, the output shaft of the rotating motor 4 being fixedly connected to the rotating disk 5, the rotating disk 5 being driven to rotate by the rotating motor 4, causing the feeding column 6 and the fiber to rotate and intertwine together, a transmission gear 12 fixedly mounted on the outer side of the rotating disk 5, and the twisting frame 2 and The lower end of the rotating frame 3 is rotatably held by a drive shaft 9. One end of the drive shaft 9 is connected to the rotating disk 5 through a drive gear 13 and a transmission gear 12. The other end of the drive shaft 9 is connected to the twisting cylinder 7 through a belt groove 11 and a transmission belt 10. When the rotating disk 5 rotates, the drive shaft 9 is driven to rotate through the meshing of the transmission gear 12 and the drive gear 13, and the drive shaft 9 drives the twisting cylinder 7 to rotate through the transmission belt 10 and the belt groove 11. A feeding column 6 is fixedly installed on one side of the rotating disk 5, and the feeding column 6 is centrally symmetrically installed on the rotating disk 5, which facilitates the installation of special fibers for feeding, interlacing and twisting during use.

[0020] Further reading is available. Figures 1 to 3 The lower end of the rotating frame 3 is fixedly installed with a mounting base 14. One end of the drive shaft 9 and the drive gear 13 are rotatably installed in the mounting base 14, which facilitates the installation and use of one end of the drive shaft 9 and the drive gear 13, and ensures stable meshing between the drive gear 13 and the drive gear 12. One end of the drive shaft 9 and the surface of the twisting cylinder 7 are both provided with belt grooves 11. The drive belt 10 is installed in the belt grooves 11, which facilitates the drive shaft 9 to drive the twisting cylinder 7 to rotate and twist during use.

[0021] As can be seen from the above description, this utility model has the following beneficial effects: When in use, the rotating motor 4 drives the rotating disk 5 to rotate, and the rotating disk 5 drives the feeding column 6 to rotate, so that multiple fibers are intertwined together. At the same time, the transmission shaft 9 drives the twisting cylinder 7 to rotate to comb the intertwined fibers, thereby ensuring that the intertwined and twisted fibers are more uniform.

[0022] Example 2: Please refer to Figures 1 to 3 As shown, based on Embodiment 1, this utility model provides a technical solution: a guide frame 8 is provided at one end of the twisting cylinder 7, the position of the guide frame 8 corresponds to the position of the rotating disk 5, and the fiber is guided by the guide frame 8 during use, thereby facilitating interlacing and twisting; the guide frame 8 includes a fixing ring 15 fixed to the outside of one end of the twisting cylinder 7, a support rod 16 is fixedly installed on one side of the fixing ring 15, and a guide ring 17 is fixedly connected to one end of the support rod 16. The smooth surface of the guide ring 17 can reduce wear during guidance.

[0023] Using the above technical solution, the fiber is guided by the guide ring 17 of the guide frame 8 during use, and the smooth surface of the guide ring 17 can reduce wear and ensure greater stability during the interlacing and twisting process.

[0024] The working principle and usage process of this utility model are as follows: In use, special fibers are installed on the feeding column 6, and then guided through the twisting thread 18 by the guide frame 8. The winding is pulled by the traction device. During winding, the rotating disk 5 is driven to rotate by the rotary motor 4, which drives the feeding column 6 and the fibers to rotate and intertwine together. When the rotating disk 5 rotates, the drive shaft 9 is driven to rotate by the meshing of the transmission gear 12 and the drive gear 13. The transmission shaft 9 drives the twisting cylinder 7 to rotate by the transmission belt 10 and the belt groove 11. The twisting is combed by the thread guidance of the internal twisting thread 18 to ensure that the twisting is more uniform and smooth. At the same time, the smooth guidance of the guide ring 17 reduces the phenomenon of wear.
