And the feeding tension adjusting assembly 7 includes a box body 9, a rectangular frame 10, guide rods 11, guide rings 12, hydraulic rods 13, a first support frame 14 and a limiting roller 15. And the tension monitoring assembly 8 includes a mounting plate 16, a second support frame 17, a tension sensor 18, a monitoring roller 19 and a support 20. The lower outer surface of the box body 9 is fixedly connected to the right side of the middle of the outer surface of the upper end of the frame 1.

[0027] The number of the hydraulic rods 13 and the limiting rollers 15 is two groups each. The number of the guide rods 11, the guide rings 12 and the guide rods 11 is four groups each. The two hydraulic rods 13 are fixedly installed in the middle of the left and right ends of the upper outer surface of the box body 9, and the cylinder body in the hydraulic rod 13 is located inside the box body 9. The four guide rings 12 are fixedly installed at the four corners of the upper outer surface of the box body 9. The four guide rods 11 are fixedly installed at the four corners of the lower outer surface of the rectangular frame 10, and the guide rods 11 penetrate through the guide rings 12 and extend into the box body 9. The outer wall of the guide rod 11 is slidably connected with the guide ring 12. The upper outer surface of the piston rod in the two hydraulic rods 13 is fixedly connected to the middle of the left and right ends of the lower outer surface of the rectangular frame 10. The four first support frames 14 are fixedly installed at the four corners of the upper outer surface of the rectangular frame 10. The two limiting rollers 15 are rotatably connected between the four first support frames 14. The number of the second support frames 17, the tension sensors 18 and the supports 20 is two groups each.

[0028] It should be noted that the present utility model is a wire drawing device for the production of polytetrafluoroethylene fibers. The cutting structure 2, heating structure 3, tensioning structure 5 and cooling structure 6 described in the text are all prior arts and have been recorded in the cited documents, and can be effectively known to those skilled in the art, so no further details will be given here. The provided tension monitoring and adjusting assembly 4 is such that the polytetrafluoroethylene fiber passes through the outer surfaces of the upper ends of the two groups of limiting rollers 15 and the outer surface of the lower end of the monitoring roller 19 and then enters the tensioning structure 5 for tensioning. Through the provided tension sensor 18, the polytetrafluoroethylene fiber exerts an upward force on the monitoring roller 19. The magnitude of the tension of the polytetrafluoroethylene fiber can be monitored through the tension sensor 18. Through the provided feeding tension adjusting assembly 7, it is convenient to adjust the magnitude of the tension of the polytetrafluoroethylene fiber as needed. By the operation of the hydraulic rod 13, the limiting roller 15 is driven to move up and down, adjusting the angle between the polytetrafluoroethylene fiber and the monitoring roller 19. When the rectangular frame 10 moves up and down, it drives the guide rod 11 to move up and down along the guide ring 12. Through the guiding of the guide ring 12, the stability of the up and down movement of the limiting roller 15 can be improved. Therefore, through the feeding tension adjusting assembly 7, it is convenient to adjust the magnitude of the tension. Appropriate tension can ensure the uniformity and stability of the fiber, thus guaranteeing the quality of the final product and ensuring the stable tension of the traction wire. When the tension of the traction wire is unstable, it will cause the diameter of the drawn fiber to be uneven, thereby affecting the quality of the drawn wire. By real-time monitoring and adjusting the tension through the tension sensor 18, this problem can be solved and the wire drawing quality can be improved.
