Description

Technical Field

[0001] This utility model relates to the technical field of graphene processing equipment, specifically a pressure forming device for graphene production. Background Technology

[0002] Graphene is a two-dimensional honeycomb lattice structure material composed of carbon atoms with sp² hybrid orbitals. Each carbon atom forms covalent bonds with three adjacent carbon atoms, forming a stable hexagonal ring arrangement. Pressure forming equipment is a key piece of equipment in graphene production, used to process graphene raw materials into sheets of specific shapes or densities through mechanical pressure and hot pressing processes to meet the application needs of electronic devices, composite materials, energy storage and other fields.

[0003] Chinese patent (authorization announcement number: CN 217834475 U, authorization announcement date: 2022.11.18) proposes a pressure forming device for graphene production, including a chassis and an extrusion assembly. The extrusion assembly is located at the top of the chassis, and a stabilizing platform is fixedly installed at the bottom of the chassis. The four corners of the top of the chassis are all fixedly connected to the cover by screws. A shaping assembly is located at the bottom of the chassis. Ventilation holes are opened on both sides of the top of the chassis. A mounting frame is fixedly installed inside each of the two ventilation holes, and several heat dissipation fins are fixedly installed inside each of the two mounting frames. By designing the fan blades at the bottom of the lower mold base, heat can be quickly discharged through the several heat dissipation holes and the ventilation holes at the top of the chassis, which facilitates the rapid cooling of graphite.

[0004] However, when the above-mentioned device is pressing graphene, the device must be opened every time the material is loaded and unloaded, the pressed material must be removed, and then the graphene must be loaded into the lower mold base. This operation results in low production efficiency and is not conducive to production needs. In order to improve the pressing and molding efficiency of graphene, we propose a pressure molding device for graphene production. Utility Model Content

This design achieves simultaneous feeding and feeding, greatly accelerating the efficiency of graphene pressing and forming, and solving the problems mentioned earlier.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-6This utility model provides a technical solution: a pressure forming device for graphene production, including a support frame 1, on which a loading assembly 2, a pressing assembly 3, a transmission assembly 4, and two sets of ejector assemblies 5 are mounted. The loading assembly 2 includes a mating frame 17, which is slidably connected to the support frame 1. Two sets of lower mold bases 18 are slidably mounted on the mating frame 17. A connecting block 10 is fixedly mounted below the mating frame 17. Several positioning holes 19 are opened on the mating frame 17. The pressing assembly 3 includes a first hydraulic cylinder 20. A limit frame 14 is fixedly mounted on the support frame 1. The first hydraulic cylinder 20 is fixedly connected to the limit frame 14. The first hydraulic cylinder 20... An installation plate 24 is fixedly installed on the output shaft. An upper mold base 23 and several positioning pins 25 are fixedly installed below the installation plate 24. The positioning pins 25 are engaged with the corresponding positioning holes 19. The transmission assembly 4 includes a transmission motor 9. A fixed frame 16 is fixedly installed below the support frame 1. The transmission motor 9 is fixedly connected to the fixed frame 16. A drive pulley 6 is fitted onto the end of the transmission shaft of the transmission motor 9. A threaded rod 11 is threadedly connected to the connecting block 10. Two sets of mating plates are fixedly installed on the support frame 1. The mating plates are rotatably connected to the threaded rod 11. A transmission pulley 8 is fixedly fitted onto one end of the threaded rod 11. A drive belt 7 is tensioned and sleeved between the transmission pulley 8 and the drive pulley 6.

[0024] In use, the lower mold base 18 with graphene installed is slidably mounted onto the mating frame 17. Then, the drive motor 9 is started, and the drive shaft of the drive motor 9 drives the drive pulley 6 to rotate. Under the action of the drive pulley 8 and the drive belt 7, the drive pulley 6 drives the threaded rod 11 to rotate. Under the constraint of the support frame 1, the connecting block 10 moves the mating frame 17 to move the lower mold base 18 with graphene installed below the pressing assembly 3. Then, the drive motor 9 is turned off, and the first hydraulic cylinder 20 is started. The output shaft of the first hydraulic cylinder 20 drives the upper mold base 2 below the mounting plate 24. 3. Moving downwards, with the cooperation of the positioning post 25 and the positioning hole 19, the upper mold base 23 is pressed into the lower mold base 18, thereby shaping the graphene in the lower mold base 18. At the same time, the other lower mold base 18 with assembled graphene is also slidably installed onto the mating frame 17. After holding the pressure for a period of time, the output shaft of the first hydraulic cylinder 20 drives the upper mold base 23 to move upwards, and then moves the pressed graphene to a suitable position. At this time, the other lower mold base 18 with assembled graphene will also be moved to the bottom of the pressing assembly 3. Then the first hydraulic cylinder 20 is started again to press.

[0025] The ejector assembly 5 includes a third hydraulic cylinder 26. Two sets of auxiliary frames 15 are fixedly installed below the support frame 1. The third hydraulic cylinder 26 is fixedly connected to the corresponding auxiliary frame 15. The output shaft of the third hydraulic cylinder 26 is fixedly mounted with a top plate 27. When in use, the third hydraulic cylinder 26 is started, and the top plate 27 on the output shaft of the third hydraulic cylinder 26 pushes the lower mold base 18 containing the pressed graphene out from the mating frame 17 for heat dissipation.

[0026] Two sets of second hydraulic cylinders 21 are fixedly installed on the mounting plate 24. A push plate 22 is fixedly installed on the output shaft of the second hydraulic cylinder 21. After a period of cooling, the corresponding second hydraulic cylinder 21 is started. The push plate 22 on the output shaft of the second hydraulic cylinder 21 pushes the lower mold base 18 out of the device. After the pressed finished product is taken out, the graphene is installed and reinstalled on the mating frame 17.

[0027] Two sets of mounting brackets 13 are fixedly installed on the front and rear sides of the support frame 1. Three sets of cooling fans 12 are fixedly embedded on the mounting brackets 13. When heat dissipation is required, the corresponding cooling fan 12 is turned on to dissipate heat from the pressed graphene, making it easy for staff to handle.

[0028] Several heat sinks are fixedly connected to the outer surface of the drive motor 9 to improve the heat dissipation performance of the drive motor 9.

[0029] Working principle: In use, the lower mold base 18 with graphene installed is slidably installed onto the mating frame 17. Then, the drive motor 9 is started. The drive shaft of the drive motor 9 drives the drive pulley 6 to rotate. Under the action of the drive pulley 8 and the drive belt 7, the drive pulley 6 drives the threaded rod 11 to rotate. Under the constraint of the support frame 1, the connecting block 10 moves the mating frame 17 to move the lower mold base 18 with graphene installed below the pressing assembly 3. Then, the drive motor 9 is turned off, and the first hydraulic cylinder 20 is started. The output shaft of the first hydraulic cylinder 20 drives the upper mold below the mounting plate 24. The upper mold base 23 moves downward, and with the cooperation of the positioning post 25 and the positioning hole 19, the upper mold base 23 is pressed into the lower mold base 18, thereby shaping the graphene in the lower mold base 18. At the same time, the other lower mold base 18 with assembled graphene is also slidably installed onto the mating frame 17. After holding the pressure for a period of time, the output shaft of the first hydraulic cylinder 20 drives the upper mold base 23 to move upward, and then moves the pressed graphene to a suitable position. At this time, the other lower mold base 18 with assembled graphene will also be moved to the bottom of the pressing assembly 3. Then the first hydraulic cylinder 20 is started again to press.

[0030] Then, the third hydraulic cylinder 26 is activated, and the top plate 27 on the output shaft of the third hydraulic cylinder 26 pushes the lower mold base 18 containing the pressed graphene out of the mating frame 17 for heat dissipation. After a period of heat dissipation, the corresponding second hydraulic cylinder 21 is activated, and the push plate 22 on the output shaft of the second hydraulic cylinder 21 pushes the lower mold base 18 out of the device. After the pressed finished product is taken out, the graphene is installed and reinstalled on the mating frame 17. When heat dissipation is required, the corresponding cooling fan 12 is turned on to dissipate heat from the pressed graphene, making it easier for workers to handle.

[0031] This design enables simultaneous feeding and unloading, greatly improving the efficiency of graphene compression molding.
