[0020] Please refer to Figures 1-2The fixed frame 2 has a sliding groove 8 in the middle of the front and rear ends. The lower end of the lifting rod 6 passes through the interior of the sliding groove 8. The lower ends of the lifting rod 6 are fixedly connected to a connecting rod 9, which is slidably connected inside the sliding groove 8. The upper end of the adjusting rod 10 is fixedly connected to the middle of the lower end of the connecting rod 9 to ensure the rationality of the structural design. The upper end of the base 1 has guide rails 14 fixedly installed on both the front and rear sides of the limiting member 12. The front and rear ends of the limiting member 12 are fixedly connected to sliders 15, which are slidably connected inside the guide rails 14. The sliders 15 slide inside the guide rails 14 to limit and support the limiting member 12. The right end of the threaded rod 16 is rotatably connected to the limiting member 12. The left end of the threaded rod 16 is fixedly installed with a rotating wheel 17, which can drive the threaded rod 16 to rotate normally by rotating the rotating wheel 17.

[0021] Please see Figures 2-3 A U-shaped component 18 is fixedly connected to the right end of the front-end I-shaped bearing seat 5. A fastener 19 is threaded through and connected to the middle of the right end of the U-shaped component 18. A stop plate 20 is rotatably connected to the left end of the fastener 19 inside the U-shaped component 18. The stop plate 20 is pressed against the fixed frame 2. When the chemical fiber is adjusted to the optimal tension, the fastener 19 can be rotated to make it press the stop plate 20 against the fixed frame 2. With the support of the lifting rod 6 and the spring 7, the pressure roller 3 is fixed, thereby avoiding the instability of the spring 7 during the conveying process from affecting the stability of the pressure roller 3, and ensuring the rationality and integrity of this technical solution.

[0022] Working principle: In use, the chemical fiber filaments wound on the conveyor roller are passed around the lower end of the pressure roller 3. By rotating the rotating wheel 17, the threaded rod 16 is rotated, which in turn drives the limiting member 12 to move left and right. When the limiting member 12 moves to the left, the roller 11 rolls downward in the inclined groove 13, causing the adjusting rod 10 and other structures to move downward under the action of gravity, ultimately driving the pressure roller 3 to descend. Conversely, the same principle applies. When the pressure roller 3 descends, it drives the chemical fiber filaments that have passed around its lower end to descend. Compared to directly controlling the raising and lowering of the pressure roller 3 to adjust the tension, this device transforms it into rolling the roller 11 on the inclined surface of the inclined groove 13. Compared to vertically descending roller 11, this method achieves the same result. The relatively large movement distance of roller 11 allows the operator to make small adjustments to roller 11 more easily during adjustment, thereby achieving precise control over the lifting and lowering of roller 3. Furthermore, when adjusting the tension between roller 3 and the chemical fiber, the design of spring 7 allows roller 3 to gently press against the chemical fiber by utilizing the support of the chemical fiber and the rebound force of spring 7. Finally, when the chemical fiber is in the optimal tension state, rotating fastener 19 can cause it to press against the abutment plate 20 and the fixing frame 2. Combined with the support of lifting rod 6 and spring 7, the roller 3 is fixed.
