[0019] Example 1, as Figure 1-3As shown, the present invention proposes a coating device for a proton exchange membrane in a fuel cell, comprising a coating machine body 1, a material roller 3, bearings 7, a tension spring 9, and a pressing assembly. The material roller 3 is disposed at one end of the coating machine body 1, and a fixing seat 2 for supporting the material roller 3 in use is provided below the end of the material roller 3. There are two bearings 7, which are respectively sleeved on one end of the material roller 3 and connected to the fixing seat 2. A pressure block 6 for pressing and fixing the bearing 7 in use is provided at the top of the bearing 7. The tension spring 9 is installed on the bottom side of the pressure block 6 and connected to the bottom side of the fixing seat 2. The pressing assembly is disposed above the material roller 3 and connected to the pressure block 6.

[0020] In an optional embodiment, a step 10 is provided at the upper end face of the fixed seat 2. The height of the step 10 is greater than the width of the pressure block 6. This is used to place the pressure block 6 and the pressing assembly in the step 10 during use, so that the material roller 3 drives the bearing 7 to be installed on the fixed seat 2, thus avoiding any obstruction to the installation of the material roller 3.

[0021] In this embodiment, by installing the bearing 7 at the end of the material roller 3 and placing the bearing 7 on the fixed seat 2, and by moving the pressing assembly, the pressing assembly moves the pressing block 6 above the bearing 7. Through the tension of the tension spring 9, the pressing block 6 is connected to the bearing 7 and the fixed seat 2 and pressure is applied to the bearing 7, thus fixing the bearing 7 on the fixed seat 2. By moving the pressing assembly upward, the pressing assembly moves the pressing block 6 upward and stretches the tension spring 9. At the same time, the pressing assembly and the pressing block 6 are moved into the step 10 and placed in the step 10, thereby disassembling the material roller 3 and the bearing 7, making the disassembly and assembly of the material roller 3 more convenient.

[0022] Example 2, as Figure 1-2 As shown, this utility model proposes a proton exchange membrane coating device for fuel cells. Compared with Embodiment 1, the difference in this embodiment is that the pressing assembly includes a pressure roller 4, a slide rail 5, a spring 13, and a slider 14. The slide rail 5 is installed on the top of the pressing block 6, the slider 14 is slidably installed on the inner side of the slide rail 5, and the size of the slider 14 is arranged to match the slide rail 5. The spring 13 is located on the inner side of the slide rail 5 and above the slider 14. The pressure roller 4 is located above the material roller 3 and is rotatably connected to the slider 14.

[0023] In this embodiment, the spring 13 drives the slider 14 to move down on the inner side of the slide rail 5, and the slider 14 drives the pressure roller 4 to contact the material wound on the material roller 3. The pressure roller 4 is rotatably connected to the slider 14, so that the pressure roller 4 rolls along with the material conveying when applying pressure to the material, ensuring that the pressure roller 4 always applies pressure to the material, so that the material on the material roller 3 is conveyed stably.

[0024] Example 3, as Figure 1-2As shown, the present invention proposes a proton exchange membrane coating device for fuel cells. Compared with the first embodiment, the difference in this embodiment is that a mounting groove 8 is provided at the top of one end of the fixed base 2, and the bearing 7 is installed at the bottom inner side of the mounting groove 8. The depth of the mounting groove 8 is greater than the diameter of the bearing 7.

[0025] In an optional embodiment, the bottom end of the pressure block 6 is inserted into the inner side of the mounting groove 8. The bottom end of the pressure block 6 is provided with a connecting groove 15, which wraps around the top end of the bearing 7. It is used to limit the pressure block 6 through the mounting groove 8 during use and to connect the pressure block 6 to the bearing 7 through the connecting groove 15, thereby increasing the connection area between the pressure block 6 and the bearing 7 and ensuring the stability of the bearing 7 during the pressing process.

[0026] In an optional embodiment, a limiting groove 11 is provided on the inner side of both the mounting groove 8 and the connecting groove 15. When the bearing 7 is installed in the mounting groove 8 and the connecting groove 15, the bearing 7 is accommodated in the limiting groove 11. The limiting groove 11 is used to limit the position of the bearing 7 during use, so as to prevent the material roller 3 and the bearing 7 from moving along the length direction of the material roller 3.

[0027] In an optional embodiment, a locking block 12 is provided on both sides of the pressure block 6. When the pressure block 6 is installed in conjunction with the mounting groove 8, the locking block 12 is accommodated in the limiting groove 11 to further limit the position of the pressure block 6 during use and improve the stability of the pressure block 6 placed in the mounting groove 8.

[0028] In this invention, the bearing 7 is installed at the end of the roller 3, and the roller 3 drives the bearing 7 to be placed in the mounting groove 8 at one end of the fixed seat 2, with the outer ring of the bearing 7 located in the limiting groove 11. Simultaneously, the pressure roller 4 drives the slide rail 5 to move, causing the slide rail 5 to move the pressure block 6 towards the inside of the mounting groove 8, so that the bottom end of the pressure block 6 is inserted into the inside of the mounting groove 8. At the same time, the tension of the tension spring 9 causes the connecting groove 15 at the bottom of the pressure block 6 to be tightly connected to the bearing 7, and the limiting groove 11 inside the connecting groove 15 wraps around the outer ring of the bearing 7, ensuring the stable installation of the bearing 7. Meanwhile, the spring 13 drives the slider 14 downwards from the inside of the slide rail 5. The slider 14 moves the pressure roller 4 to contact the material wound on the material roller 3. The pressure roller 4 is rotatably connected to the slider 14, so that the pressure roller 4 rolls along with the material conveying when applying pressure to the material, ensuring that the pressure roller 4 always applies pressure to the material, so that the material on the material roller 3 is conveyed stably. By moving the pressure roller 4 upward, the pressure roller 4 drives the spring 13 to compress through the slider 14, which in turn drives the slide rail 5 to move upward. The upward movement of the slide rail 5 causes the pressure block 6 to separate from the mounting groove 8, and the pressure block 6 and the slide rail 5 to move into the step 10, so that they are placed in the step 10, and the material roller 3 is disassembled from the bearing 7, making the disassembly and assembly of the material roller 3 more convenient.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
