[0032] Embodiment, refer to Figures 1 to 9A production equipment for high load-bearing capacity battery separators includes a drive motor 1 and three conveying boxes 2. The output end of the drive motor 1 is connected to two spiral conveying structures 7 via a gear assembly. The upper sidewalls of the front ends of the two conveying boxes 2 located in the middle and rear are provided with mixing troughs. The inner sidewalls of the mixing troughs are fixedly connected to synchronous heating chambers 12. The synchronous heating chambers 12 are provided with mixing and heating chambers 11. The top of the mixing and heating chambers 11 is connected to two storage chambers 9 via two preheating chambers 10. The side walls and bottom ends of the two conveying boxes 2 located in the middle and rear are provided with dispersion troughs. The inner sidewalls of the dispersion troughs are connected to mixing components for mixing additives. The mixing components are connected to storage boxes 19 via pipes.

[0033] Furthermore, the gear assembly consists of a drive gear 5 and two driven gears 6. The output end of the drive motor 1 is fixedly connected to the drive gear 5 via a drive shaft. The drive gear 5 meshes with one driven gear 6, and the two driven gears 6 mesh with each other. The two driven gears 6 are respectively fixedly connected to two screw conveyor structures 7. The drive motor 1 is fixedly connected to the front conveying box 2. The top of the front conveying box 2 is connected to a feed hopper 8. Multiple supports 4 are connected to the outer walls of the three conveying boxes 2. The rear conveying box 2 is fixedly connected to a thermoplastic mold 3. The bottom end of the storage chamber 9 is connected to the preheating chamber 10 via a control valve. The bottom end of 10 is connected to the mixing chamber 11 via a control valve. The mixing chamber 11 is connected to the synchronous heating chamber 12 via a control valve. The two storage chambers 9 at the front are respectively filled with carbon fiber and oxidizing agent. The two storage chambers 9 at the rear are respectively filled with graphene and oxidizing agent. The bottom end of the mixing chamber 11 is connected to the temporary storage chamber 13 via a control valve. The bottom end of the temporary storage chamber 13 is fixedly connected to the mixing chamber 14. The mixing component consists of the mixing chamber 15 and the sealing baffle 17. The inner wall of the mixing chamber 15 is fixedly connected to the sealing baffle 17 via a hydraulic push rod 16. The mixing chamber 15 is connected to the storage box 19 via two guide pipes 18.

[0034] It should be noted that: Starting the drive motor 1 drives the drive gear 5 to rotate via the drive shaft. The rotation of drive gear 5 sequentially drives two meshing driven gears 6 to rotate, which in turn drives the two screw conveyor structures 7 to rotate in the opposite direction. Subsequently, the polyimide, heated to a molten state, is added from the feed hopper 8 along with the additives to the front conveying box 2. The screws of the two screw conveyor structures 7 shear the additives, ensuring they are evenly dispersed in the molten polyimide matrix. The molten polyimide matrix is ​​continuously conveyed to the middle conveying box 2. Before this, the carbon fibers and oxidant in the two front storage chambers 9 are controlled and added to the preheating chamber 10, with the location of the carbon fibers and oxidant controlled. The temperature of the two preheating chambers 10 is maintained at 60℃–120℃. Then, the carbon fiber is added to the synchronous heating chamber 12 under control. After the carbon fiber oxidation is completed, it is controlled to enter the temporary storage chamber 13 and the oxidized carbon fiber is heated to 300℃–400℃ to facilitate the subsequent synchronous mixing temperature with the polyimide molten matrix. Then, the mixing chamber V 14 is controlled to move down to allow the oxidized carbon fiber to be mixed in synchronously. During this process, the hydraulic push rod 16 retracts and drives the sealing baffle 17 to move outward, so that the mixing chamber 15 is connected to the dispersion tank in the conveying box 2. Then, the additive in the storage box 19 is guided and transported to the conveying box 2 through the guide pipe 18 for mixing, so as to avoid the agglomeration of the mixed materials.

[0035] Simultaneously, the graphene and oxidant in the two rear storage chambers 9 are subjected to the above-mentioned synchronous operation, wherein the temperature before graphene oxidation is precisely controlled.

[0036] The advantages mentioned above are: this allows for the oxidation of carbon fibers and graphene during the mixing process, which facilitates the improvement of the surface activity of carbon fibers and graphene, enables them to be better dispersed in the polyimide matrix, and enhances the interfacial bonding force, thereby improving the performance of the composite material.

[0037] The upper sidewalls of the rear ends of the two material boxes 2 located in the middle and rear are provided with detection slots. The inner sidewall of the detection slot located in the front is connected to a strength detection cover 20. The inner sidewall of the strength detection cover 20 is connected to an equal pressure detection plate 24. The top of the equal pressure detection plate 24 is connected to a magnetic control component.

[0038] Furthermore, the magnetic control assembly consists of two electromagnetic plates 21 and two permanent magnet plates 23. The top of the strength detection cover 20 is fixedly connected to the two electromagnetic plates 21 through a fixing plate. The electromagnetic plates 21 are fixedly connected to the permanent magnet plates 23 through an energy storage telescopic rod 22. The bottom of the permanent magnet plates 23 is fixedly connected to the isobaric detection plate 24 through a fixing rod. A distance sensor 25 is fixedly connected to the bottom of the fixing plate.

[0039] It should be noted that after carbon fiber is added to the polyimide molten matrix, current is passed through the electromagnetic plate 21, causing the electromagnetic plate 21 to generate a magnetic repulsion force on the permanent magnet plate 23, causing the permanent magnet plate 23 to gradually press down and perform a compression test on the polyimide molten matrix. The displacement change of the isobaric detection plate 24 is measured by the distance sensor 25. Then, current in the opposite direction is passed through the electromagnetic plate 21, causing the electromagnetic plate 21 to generate a magnetic attraction force on the permanent magnet plate 23, compressing the energy storage telescopic rod 22 and storing elastic force. Then, the power to the electromagnetic plate 21 is turned off, and the isobaric detection plate 24 impacts the polyimide molten matrix under the action of the energy storage telescopic rod 22. At this time, the displacement change of the isobaric detection plate 24 is measured by the distance sensor 25.

[0040] The advantages mentioned above are as follows: by changing the direction of the current flowing through the electromagnetic plate 21, the direction of the magnetic force can be changed to adjust the movement direction of the permanent magnet plate 23, thereby enabling the testing of the extrusion and impact of the polyimide molten matrix, and making it easier to measure the overall strength performance of the polyimide molten matrix with added carbon fibers.

[0041] The inner wall of the detection tank located at the rear is connected to a measuring cover 26, the inner wall of the measuring cover 26 is connected to a sampling cone plate 32, the top of the sampling cone plate 32 is connected to an electrolytic cell 30, and a measuring component is installed inside the electrolytic cell 30.

[0042] Furthermore, the electrical measurement assembly consists of a pusher plate 28 and a simulated cavity 29. The top of the electrical measurement cover 26 is fixedly connected to the pusher plate 28 via a control push rod 27. The simulated cavity 29 is connected to the sampling cone plate 32. The simulated cavity 29 is set inside the electrolytic cell 30. An external power supply 31 is set outside the electrolytic cell 30.

[0043] It should be noted that after graphene is added to the polyimide molten matrix, the control push rod 27 is activated and the push plate 28 is moved upward, so that the polyimide molten matrix is ​​pressed into the simulated diaphragm 29 through the sampling cone plate 32, simulating the state of the diaphragm. The simulated diaphragm 29 can be freely passed through by ions. Then, the ion displacement change in the electrolytic cell 30 is controlled by the external power supply 31, thereby detecting the overall ionic conductivity of the polyimide molten matrix after the addition of graphene.

[0044] The advantages mentioned above are as follows: the simulated membrane state in the simulated cavity 29 can be used to detect whether the overall ionic conductivity of the polyimide molten matrix is ​​qualified and uniform, ensuring that the membrane structure performance and ionic conductivity of the polyimide molten matrix produced subsequently meet the standards.

[0045] In use, the drive motor 1 is started, which drives the drive gear 5 to rotate via the drive shaft. The rotation of the drive gear 5 sequentially drives the two meshing driven gears 6 to rotate, which in turn drives the two spiral conveying structures 7 to rotate in the opposite direction. Subsequently, the polyimide is heated to a molten state and added together with the additive from the feed hopper 8 into the front conveying box 2. The screws of the two spiral conveying structures 7 shear the additive to ensure that it is evenly dispersed in the polyimide molten matrix, and continuously convey the polyimide molten matrix to the middle conveying box 2. Before this, the carbon fiber and oxidant in the two front storage chambers 9 are controlled to be added into the preheating chamber 10, and the location of the carbon fiber and oxidant is controlled. The two preheating chambers 10 are kept at 60℃–120℃. Then, the carbon fiber is added to the synchronous heating chamber 12 under control. After the carbon fiber oxidation is completed, it is controlled to enter the temporary storage chamber 13 and the oxidized carbon fiber is heated to 300℃–400℃ to facilitate the subsequent synchronous mixing temperature with the polyimide molten matrix. Then, the mixing chamber V 14 is controlled to move down to allow the oxidized carbon fiber to be mixed in synchronously. During this process, the hydraulic push rod 16 retracts and drives the sealing baffle 17 to move outward, so that the mixing chamber 15 is connected to the dispersion tank in the conveying box 2. Then, the additive in the storage box 19 is guided and transported to the conveying box 2 through the guide pipe 18 for mixing, so as to avoid the agglomeration of the mixed materials.

[0046] Simultaneously, the graphene and oxidant in the two rear storage chambers 9 are subjected to the above-mentioned synchronous operation. The temperature before graphene oxidation is precisely controlled so that the carbon fiber and graphene can be oxidized during the mixing process, which facilitates the improvement of the surface activity of carbon fiber and graphene, allows them to be better dispersed in the polyimide matrix, and enhances the interfacial bonding force, thereby improving the performance of the composite material.

[0047] After adding carbon fiber to the polyimide molten matrix, an electric current is passed through the electromagnetic plate 21, causing it to generate a magnetic repulsion force on the permanent magnet plate 23. This causes the permanent magnet plate 23 to gradually press down, performing a compression test on the polyimide molten matrix. The displacement change of the isobaric detection plate 24 is measured by the distance sensor 25. Subsequently, an electric current in the opposite direction is passed through the electromagnetic plate 21, causing it to generate a magnetic attraction force on the permanent magnet plate 23. This compresses the energy storage telescopic rod 22 and stores elastic force. Then, the electromagnetic plate... When power is cut off at 21, the isobaric testing plate 24 impacts the polyimide molten matrix under the action of the energy storage telescopic rod 22. At this time, the displacement change of the isobaric testing plate 24 is measured by the distance sensor 25. In this way, the change in the direction of the current supplied by the electromagnetic plate 21 can be used to adjust the movement direction of the permanent magnet plate 23, realize the test changes of the extrusion and impact on the polyimide molten matrix, and facilitate the measurement of the overall strength performance of the polyimide molten matrix with added carbon fiber.

[0048] After graphene is added to the polyimide molten matrix, the control push rod 27 is activated and the pusher plate 28 is moved upward, so that the polyimide molten matrix is ​​pressed into the simulated diaphragm 29 through the sampling cone plate 32, simulating the state of the diaphragm. The simulated diaphragm 29 can be freely passed through by ions. Then, the ion displacement change in the electrolytic cell 30 is controlled by the external power supply 31, thereby detecting the overall ionic conductivity of the polyimide molten matrix after the addition of graphene. In this way, the simulated diaphragm state in the simulated diaphragm 29 can be used to detect whether the overall ionic conductivity of the polyimide molten matrix is ​​qualified and uniform, ensuring that the diaphragm structure performance and ionic conductivity of the polyimide molten matrix produced later are balanced and meet the standards.
