For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] like Figures 1 to 6 As shown: A carbon fiber precursor winding and unwinding device, comprising:

[0039] An unwinding component 1 is arranged on a working plane to unwind the carbon fiber precursor;

[0040] The winding assembly 2 is arranged on the working plane to wind up the carbon fiber precursor, and the winding assembly 2 and the unwinding assembly 1 are 180° centrally symmetrical structures with each other;

[0041] The tension component 3 is arranged between the unwinding component 1 and the winding component 2 , and the unwinding carbon fiber precursor passes through the tension component 3 and enters the winding component 2 .

[0042] The tension control of the tension component 3 avoids the twisting of the raw silk during the unwinding and winding process. The tension component 3 ensures that the tension is consistent throughout the unwinding and winding process to ensure the accuracy of the test results. The 180° central symmetrical structural design of the unwinding component 1 and the winding component 2 helps to balance and stabilize the raw silk path and prevent it from twisting.

[0043] In this embodiment, the unwinding assembly 1 comprises:

[0044] An unwinding shaft 11, the unwinding shaft 11 is horizontally arranged, and carbon fiber precursor is wound on the unwinding shaft 11;

[0045] A first pressing assembly 12, which is disposed at one end of the unwinding shaft 11 in the horizontal direction and can move in a direction close to or away from the unwinding shaft 11 to press the carbon fiber precursor on the unwinding shaft 11;

[0046] The lead-out assembly 13 leads the carbon fiber precursor from the unwinding shaft 11 .

[0047] The first clamping assembly 12 moves in a direction close to or away from the unwinding shaft 11 as needed, exerting appropriate pressure on the carbon fiber precursor to ensure the tightness of the precursor during the unwinding process. This can prevent the precursor from loosening during the unwinding process, thereby maintaining the stability of the tension. The carbon fiber precursor is smoothly led out through the lead-out assembly 13 to ensure the straightness and smoothness of the precursor path. The lead-out assembly 13 reduces the friction between the precursor and the equipment through its design (such as the guide wheel), reducing the risk of wear and damage. Combined with the tension assembly 3, the tension of the precursor is more uniform and controllable during the entire unwinding process, improving the overall performance of the unwinding device and the accuracy of the test results.

[0048] Wherein, the first pressing assembly 12 comprises:

[0049] A clamping shaft 121, wherein the clamping shaft 121 is arranged parallel to the unwinding shaft 11;

[0050] The first linear module 122 drives the clamping shaft 121 to move in a direction close to or away from the unwinding shaft 11 .

[0051] The first linear module 122 can drive the clamping shaft 121 to move precisely in the direction of approaching or moving away from the unwinding shaft 11 to adjust the clamping force on the carbon fiber precursor. During the unwinding process, the linear module adjusts the position of the clamping shaft 121 according to real-time needs, so that the carbon fiber precursor always maintains an appropriate degree of tightness to prevent loosening or sliding. The combination of the clamping shaft 121 and the linear module further enhances the stability of the precursor during the unwinding process and reduces the influence of twisting and other unstable factors.

[0052] In this embodiment, the first pressing assembly 12 further includes:

[0053] The precursor guide structure 123 is arranged at the clamping shaft 121, moves with the clamping shaft 121, and the carbon fiber precursor unwound from the unwinding shaft 11 is led out through the precursor guide structure 123. The precursor guide structure 123 includes:

[0054] A guide yarn buckle 1231, which is disposed at the top of the pressing shaft 121 and moves longitudinally along the length direction of the pressing shaft 121;

[0055] The second linear module 1232 is used to drive the guide yarn buckle 1231 to move longitudinally.

[0056] The use of the raw wire guide structure 123 effectively avoids the twisting and entanglement of the raw wire during the unwinding process. The precise guidance of the raw wire guide structure 123 and the stable compression of the compression assembly further enhance the stability of the raw wire during the unwinding process.

[0057] As a preferred embodiment of the above embodiment, the axes of the clamping shaft 121 and the unwinding shaft 11 are located at the same height.

[0058] The axes of the clamping shaft 121 and the unwinding shaft 11 are located at the same height, ensuring that the original wire is evenly stressed during the unwinding process, further reducing the influence of unstable factors.

[0059] A plurality of guide rollers 131 are arranged at the top of the unwinding assembly 1 for guiding the path of the carbon fiber precursor.

[0060] The setting of the guide roller 131 ensures that the path of the carbon fiber precursor is stable and straight during the unwinding process, reducing the possibility of twisting and winding.

[0061] The structure of the winding assembly 2 is the same as that of the unwinding assembly 1 and is used for winding the carbon fiber precursor.

[0062] As a preferred embodiment of the above, the tension assembly 3 includes:

[0063] A plurality of tension rollers 31, through which the carbon fiber precursor passes, the tension rollers 31 are arranged horizontally, and the number of the tension rollers 31 is greater than 1 and is an odd number;

[0064] The driving mechanism 32 includes a motor 321 and a belt 322 . The motor 321 drives one of the tension rollers 31 to rotate, and the belt 322 drives the other tension rollers 31 to rotate together.

[0065] Several tension rollers 31 are arranged horizontally, and the carbon fiber precursor passes through these tension rollers 31 in turn. The contact and friction between the rollers control the tension of the precursor. The motor 321 drives one of the tension rollers 31 to rotate, and the belt 322 connects all the tension rollers 31 to ensure that the remaining tension rollers 31 rotate synchronously. After the motor 321 is started, the belt 322 drives all the tension rollers 31 to rotate synchronously, so that each tension roller 31 applies a uniform force to the precursor, ensuring the stability and uniformity of the tension. Ensure that the tension of the carbon fiber precursor remains consistent during the unwinding and winding process, thereby improving the overall performance of the unwinding and winding device and the accuracy of the test results.

The above embodiments and the description are only for explaining the principle of the present invention.
