[0011] The beneficial effects of this utility model are:

[0012] In this invention, the fiber cloth is guided by a first guide roller, a second guide roller, a third guide roller, and a fourth guide roller to complete the resin impregnation operation. The thickness of the fiber cloth after resin impregnation is detected by a microwave thickness sensor, and the detected data is transmitted to the controller in the form of an electrical signal. The controller compares the detected data with a preset value and then sends an electrical signal to the servo motor at the second adjustment mechanism. This causes the servo motor to drive the relative movement mechanism, so that the first and second adjustment rollers move relative to each other, thereby adjusting the gap and removing excess resin from the top and bottom of the fiber cloth. Compared with the prior art, this invention avoids the drawbacks of manual control through intelligent thickness detection and intelligent thickness adjustment control, making operation convenient and improving the resin impregnation efficiency.

[0013] In this invention, by placing the first adjustment mechanism in front of the microwave thickness sensor, the thickness of the resin-impregnated fiber cloth can be pre-controlled. This ensures that after the fiber cloth passes through the first adjustment mechanism, the resin thickness at the top and bottom of the fiber cloth remains consistent. Consequently, after passing through the second adjustment mechanism, the resin thickness at both ends of the fiber cloth remains consistent, thus improving the symmetry of the fiber cloth after impregnation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-5 The intelligent adjustment device for the impregnation thickness of fiber cloth includes an impregnation tank 1 and a fiber cloth 2. A first guide roller 3, a third guide roller 4, and a fourth guide roller 5 are sequentially and parallelly arranged on the top of the impregnation tank 1. A second guide roller 6 is rotatably connected to the inner walls of both sides of the impregnation tank 1, positioned between the first guide roller 3 and the third guide roller 4. The fiber cloth 2 passes through the upper surface of the first guide roller 3, the lower surface of the second guide roller 6, and the upper surfaces of the third guide roller 4 and the fourth guide roller 5. A first frame 7 is provided on the impregnation tank 1, positioned between the third guide roller 4 and the fourth guide roller 5. A first adjustment mechanism 8 and a second adjustment mechanism 9 are provided on the first frame 7, with the first adjustment mechanism 8 positioned close to the third guide roller 4. The second adjustment mechanism 9 is arranged close to the fourth guide roller 5. The first adjustment mechanism 8 and the second adjustment mechanism 9 are both composed of a servo motor 10, a relative movement mechanism 11, a first adjustment roller 12 and a second adjustment roller 13. The fiber cloth 2 located between the third guide roller 4 and the fourth guide roller 5 is arranged below the first adjustment roller 12 and above the second adjustment roller 13. A microwave thickness sensor 14 is provided on the top of the inner wall of the first frame 7. The microwave thickness sensor 14 is arranged between the first adjustment mechanism 8 and the second adjustment mechanism 9. A controller 15 is provided on the first frame 7. The servo motors 10 at the microwave thickness sensor 14 and the second adjustment mechanism 9 are connected to the controller 15 by electrical signals.

[0022] The first guide roller 3 is the unwinding end of the fiber cloth 2. Guided by the first guide roller 3, the second guide roller 6, the third guide roller 4, and the fourth guide roller 5, the fiber cloth 2 completes the operations of entering the impregnation tank 1, impregnating, and removing from the impregnation tank 1 after impregnation. After impregnation, the fiber cloth 2 passes through the first adjustment mechanism 8. The servo motor 10 at this location is activated, and the servo motor 10 drives the relative movement mechanism 11, causing the first adjustment roller 12 and the second adjustment roller 13 at this location to move relative to each other, thereby adjusting the gap. Thus, when the impregnated fiber cloth 2 passes between the first adjustment roller 12 and the second adjustment roller 13 at this location, a portion of the excess resin glue on the top and bottom ends of the fiber cloth 2 is removed, ensuring that the thickness is greater than the required thickness, while ensuring that the thickness of the resin glue at the top and bottom ends of the fiber cloth 2 is consistent. After the fiber cloth 2 completes the thickness pre-adjustment, it passes under the microwave thickness sensor 14. The microwave thickness sensor 14 detects the real-time thickness of the fiber cloth 2 and transmits the detected data to the controller 15 in the form of an electrical signal. 5. After comparing the detection data with the preset value, the total resin thickness at the top and bottom is obtained by subtracting the thickness of the fiber cloth 2 itself. The controller 15 sends the calculated data to the servo motor 10 at the second adjustment mechanism 9 in the form of an electrical signal, so that the servo motor 10 drives the relative movement mechanism 11, so that the first adjustment roller 12 and the second adjustment roller 13 complete relative movement to achieve spacing adjustment. This spacing is the required impregnation thickness of the fiber cloth 2. The excess resin thickness on the top and bottom of the fiber cloth 2 is removed. Compared with the existing technology, the intelligent thickness detection and intelligent thickness adjustment control avoid the drawbacks of manual control. While being easy to operate, it improves the impregnation efficiency. Furthermore, through the pre-control design, the consistency of the resin thickness at the top and bottom of the fiber cloth 2 after impregnation is ensured, thus providing a benchmark for the subsequent thickness detection and control of the fiber cloth 2. This ensures the symmetry and consistency of the resin thickness at the top and bottom of the fiber cloth 2 after secondary thickness control, thereby improving the impregnation quality.

[0023] Specifically, in this embodiment, the relative movement mechanism 11 consists of a bidirectional lead screw 16, a first moving block 17, and a second moving block 18. The bidirectional lead screw 16 is connected to the output shaft of the servo motor 10. The first moving block 17 and the second moving block 18 are respectively driven to the positive and negative lead screw sections of the bidirectional lead screw 16. The first adjusting roller 12 is rotatably connected to the first moving block 17, and the second adjusting roller 13 is rotatably connected to the second moving block 18. This allows the servo motor 10 to drive the bidirectional lead screw 16 to rotate in one direction, achieving a synchronous relative movement effect where the first moving block 17 drives the first adjusting roller 12, and the second moving block 18 drives the second adjusting roller 13. This ensures the consistency of the resin thickness at the top and bottom of the fiber cloth 2 during the pre-adjustment and secondary adjustment processes.

[0024] Specifically, in this embodiment, the relative movement mechanism 11 further includes a guide rod 19, a first guide block 20, and a second guide block 21. The guide rod 19 is disposed on the side of the first frame 7 away from the servo motor 10. The first guide block 20 and the second guide block 21 are both slidably connected to the guide rod 19. The end of the first adjusting roller 12 away from the first moving block 17 is rotatably connected to the first guide block 20, and the end of the second adjusting roller 13 away from the second moving block 18 is rotatably connected to the second guide block 21, thereby improving the overall stability of the first adjusting roller 12 and the second adjusting roller 13 and ensuring the horizontal effect during the movement.

[0025] Specifically, in this embodiment, the distance between the microwave thickness sensor 14 and the first adjustment mechanism 8 is less than the distance between the microwave thickness sensor 14 and the second adjustment mechanism 9. The microwave thickness sensor 14 is close to the first adjustment mechanism 8, providing sufficient time for the second adjustment mechanism 9 to receive the electrical signal from the controller 15 and make a substantial response.

[0026] Specifically, in this embodiment, a second support 22 is provided at the top of the impregnation tank 1. The second support 22 is arranged between the first guide roller 3 and the second guide roller 6. An electric telescopic rod 23 is provided on the second support 22. A connecting frame 24 is provided at the bottom end of the telescopic shaft of the electric telescopic rod 23. A first dust removal roller 25 is rotatably connected to the bottom end of the connecting frame 24. A second dust removal roller 26 is rotatably connected between the inner walls of the two sides of the second support 22. The fiber cloth 2 located between the first guide roller 3 and the second guide roller 6 is arranged below the first dust removal roller 25 and above the second dust removal roller 26 to provide a dust removal effect for the fiber cloth 2 before entering the impregnation tank 1, preventing dust and debris from adhering to the fiber cloth 2 and causing deviations in thickness after impregnation.

[0027] Specifically, in this embodiment, a first spray pipe 27 and a second spray pipe 28 are arranged between the inner walls of both sides of the first frame 7. The first spray pipe 27 and the second spray pipe 28 are arranged between the third guide roller 4 and the first adjustment mechanism 8. Several nozzles 29 are provided at the bottom end of the first spray pipe 27 and the top end of the second spray pipe 28. The fiber cloth 2 located between the third guide roller 4 and the first adjustment mechanism 8 is arranged between the first spray pipe 27 and the second spray pipe 28. An extraction pump 30 is provided in the impregnation tank 1. The first spray pipe 27 and the second spray pipe 28 are both connected to the extraction pump 30 through pipelines. The extraction pump 30 extracts the resin in the impregnation tank 1 and delivers it to the first spray pipe 27 and the second spray pipe 28 through pipelines. The resin is then sprayed onto the top and bottom ends of the fiber cloth 2, which is about to enter the first adjustment mechanism 8 for pre-adjustment, through the nozzles 29, so as to reduce the amount of resin lost from the fiber cloth 2 under the pressure of the third guide roller 4.

[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
