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.

[0026] Example 1:

[0028] A fan 35 is fixedly connected to the top surface of the inner wall of the movable frame 3. The fan 35 is located between the flattening roller 34 and the cooling roller 33. The fan 35 further cools the pre-cooled impregnated paper to ensure that the impregnated paper is further cooled. At the same time, the airflow blown out by the fan 35 can sweep away the micro-dust that was not completely removed by the cleaning roller 32 and remove the residual cleaning agent volatiles during the cleaning process.

[0029] Example 2:

[0030] Please see Figure 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. A connecting frame 31 is fixedly connected to the top surface of the movable frame 3, and an electric cylinder 21 is fixedly connected to the top surface of the portal frame 2. The piston rod end of the electric cylinder 21 passes through the portal frame 2 and is fixedly connected to the top surface of the connecting frame 31. When adjusting the position of the cleaning roller 32, the cooling roller 33 and the flattening roller 34, the electric cylinder 21 is opened. The cleaning roller 32 drives the connecting frame 31 to move through the piston rod, and the connecting frame 31 drives the movable frame 3 to move.

[0031] The movable frame 3 is rotatably equipped with a first rotating shaft 41, a bushing 42, and a second rotating shaft 43 on both sides. The second rotating shaft 43 is fixedly connected to the end of the flattening roller 34, the bushing 42 is fixedly connected to the end of the cooling roller 33, and the first rotating shaft 41 is fixedly connected to the end of the cleaning roller 32. The rotation of the first rotating shaft 41 drives the cleaning roller 32 to rotate, the rotation of the bushing 42 drives the cooling roller 33 to rotate, and the rotation of the second rotating shaft 43 drives the flattening roller 34 to rotate.

[0032] A motor 4 is fixedly connected to one side of the outer wall of the movable frame 3. The end of a first rotating shaft 41 passes through the movable frame 3 and is fixedly connected to the rotating shaft of the motor 4. Four transmission wheels 44 and two transmission belts 45 are provided on the outer wall of the movable frame 3 away from the motor 4. The first rotating shaft 41 and the second rotating shaft 43 on the outer wall of the movable frame 3 away from the motor 4 are both fixedly connected to the transmission wheels 44. Two transmission wheels 44 are fixedly connected to the bushing 42 on the outer wall of the movable frame 3 away from the motor 4. Two adjacent transmission wheels 44 located on the same vertical plane are connected to the corresponding transmission belts 45. When the motor 4 is turned on, the motor 4 rotates and drives the first rotating shaft 41 to rotate. The rotation of the first rotating shaft 41 drives the cleaning roller 32 to rotate. During the rotation of the cleaning roller 32, impurities and fibers on the impregnated paper are removed. At the same time, the rotation of the first rotating shaft 41 drives the transmission wheels 44 on it to rotate. The transmission wheels 44 drive the other transmission wheels 44 to rotate through the transmission belts 45, thereby completing the synchronous rotation of the cleaning roller 32, the cooling roller 33 and the flattening roller 34.

[0033] A coolant storage box 5 and a water pump 51 are fixedly connected to the top surface of the outer wall of the portal frame 2. The water pump 51 is connected to the coolant storage box 5. A second hose 53 is connected to one side of the water pump 51, and a first hose 52 is connected to one side of the coolant storage box 5. High-speed rotary joints 54 are installed in the middle of the two bushings 42. The high-speed rotary joints 54 are connected to the cooling roller 33. The two high-speed rotary joints 54 are respectively connected to one end of the first hose 52 and the second hose 53. When the water pump 51 is turned on, the water pump 51 draws out the coolant from the coolant storage box 5. The coolant moves through the second hose 53 to the high-speed rotary joint 54 and then to the inside of the cooling roller 33, thereby completing the subsequent cooling. The cooled coolant returns to the coolant storage box 5 through the first hose 52 for subsequent reuse.

[0034] The top of the mobile frame 3 has a through hole 36, and the fan 35 is located directly below the through hole 36. The two sides of the gantry frame 2 have through holes 22, through which the first flexible hose 52 and the second flexible hose 53 pass. The through hole 36 helps the fan 35 to deliver air, and the through hole 22 helps the first flexible hose 52 and the second flexible hose 53 to be used normally.

[0035] Example 3:

[0036] Please see Figure 1-4This is the third embodiment of the present invention, based on the above two embodiments. In use, the impregnated paper is placed on the top surface of the workbench 1. The electric cylinder 21 is turned on, and the electric cylinder 21 drives the connecting frame 31 to move via the piston rod. The moving frame 31 drives the moving frame 3 to move, and the moving frame 3 causes the cleaning roller 32, cooling roller 33, and flattening roller 34 at the bottom to contact the impregnated paper. The motor 4 is turned on, and the rotation of the motor 4 drives the first rotating shaft 41 to rotate. The rotation of the first rotating shaft 41 drives the cleaning roller 32 to rotate. During the rotation of the cleaning roller 32, impurities and fibers on the impregnated paper are removed. Simultaneously, the rotation of the first rotating shaft 41 drives the transmission wheel 44 on it to rotate. The transmission wheel 44 drives another transmission wheel 44 to rotate via the transmission belt 45, thus completing the synchronous rotation of the cleaning roller 32, cooling roller 33, and flattening roller 34. The water pump 51 is turned on, and the water pump 51 draws out the coolant from the coolant storage box 5. The coolant moves at high speed through the second hose 53. The rotary joint 54 moves to the inside of the cooling roller 33. When the cleaned impregnated paper moves to the position of the cooling roller 33, the cooling roller 33 initially cools the impregnated paper. After the coolant is used up, it returns to the coolant storage box 5 for easy reuse. The initially cooled impregnated paper continues to move forward. When it reaches the position of the fan 35, the fan 35 further cools the paper by blowing air. After cooling, the impregnated paper is flattened by the flattening roller 34 and removed from the device. In this utility model, the cleaning roller 32 removes impurities and fibers from the surface of the impregnated paper before cooling, which improves the overall quality of the impregnated paper. Then, the two-stage cooling by the cooling roller 33 and the fan 35 reduces the temperature difference between the inside and outside of the paper, avoiding internal wrinkling or breakage of the paper due to heat stress concentration. The airflow blown out by the fan 35 can sweep away the dust that the cleaning roller 32 has not completely removed and remove the residual cleaning agent volatiles during the cleaning process, avoiding local softening or delamination of the adhesive layer caused by solvent backflow.
