Description

A graphene film drying device Technical Field

[0001] This utility model relates to the field of graphene film production technology, and in particular to a graphene film drying device. Background Technology

[0002] Graphene films, made from multilayer graphene, possess advantages such as high conductivity, high transparency, high strength, high thermal conductivity, and high flexibility. They are widely used in fields such as electronic devices, composite materials, energy storage devices, biomedicine, and nanotechnology. However, during the preparation and processing of graphene films, after cleaning to remove contaminants or residual chemicals from the surface, the graphene films need to be dried to avoid residual moisture. Currently, the surface drying process for graphene films mainly involves passing the film through a drying zone, where drying gases evaporate the moisture on the film. This method results in a consistent heat distribution across the surface, leading to low drying efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a graphene film drying device to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A graphene film drying device includes a support mechanism, which includes a drying chamber. The drying chamber has inlets and outlets on its two side walls. A fan is installed at the top of the drying chamber. A guide mechanism is installed inside the drying chamber to redirect and support the graphene film as it passes through. The guide mechanism causes the graphene film to sequentially form a wavy, vertical, and horizontal shape within the drying chamber. A drying mechanism is also installed inside the drying chamber to treat surface moisture of the graphene film. The drying mechanism includes a cleaning component located in the upward region of the wavy section of the graphene film and a processing component located in the vertical section of the graphene film. The processing component includes rotating tubes positioned opposite each other on both sides of the vertical section of the graphene film. The rotating tubes are rotatably mounted on the drying chamber, with their rear ends passing through the drying chamber and connected to a drying air source. An arc-shaped plate is installed on the rotating tube within the drying chamber. Spray nozzles are evenly distributed on the opposite surface of the arc-shaped plate. A cavity communicating with the rotating tube is located inside the arc-shaped plate. A power component is installed at the front end of the rotating tube to cause it to rotate intermittently.

[0006] Further configuration: The power assembly includes a transmission gear fixed to the front end of the rotating tube, the transmission gears meshing with each other, a support shaft fixed to the front wall of the drying chamber, a sector gear on the support shaft meshing with one of the transmission gears, a swing plate fixed to the front end of the sector gear, a sliding groove on the swing plate, a mounting base fixed on the side of the drying chamber away from the transmission gear of the sector gear, a motor mounted on the side wall of the mounting base, a rotating disk fixed on the output shaft of the motor, a transmission boss on the rear end face of the rotating disk, the transmission boss engaging with the sliding groove on the swing plate.

[0007] Further configuration: The swing plate and the rotating tube are on the same horizontal plane, and the transmission boss is slidably connected to the groove of the swing plate.

[0008] Further configuration: The swing plate and the sector gear are fixed together, and the sector gear and the swing plate are rotatably connected to the support shaft.

[0009] Further configuration: The guiding mechanism includes a first support roller, a second support roller, a third support roller, and a fourth support roller that are sequentially rotated inside the drying chamber. The first support roller is close to the feed inlet. The first support roller, the second support roller, and the third support roller form a wave-like support for the graphene film, while the third support roller and the fourth support roller form a vertical support for the graphene film.

[0010] Further setup: The cleaning component includes connecting pipes on the upper and lower sides of the wavy graphene film. The rear end of the connecting pipe passes through the drying chamber and is connected to a drying air source. The lower end of the connecting pipe is connected to a flat nozzle, which is tilted towards the center and blows out gas that crosses the surface of the graphene film it passes over.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

The cleaning component performs preliminary treatment on the moisture in the wavy sections of the graphene film. The power component drives the arc plate and nozzle on the rotating tube to rotate intermittently, drying the vertical sections of the graphene film in different airflow directions, thereby improving the efficiency of drying the graphene film.

[0025] The present invention will be further described below with reference to the accompanying drawings:

[0026] As shown in Figures 1-7, a graphene film drying device includes a support mechanism, which includes a drying chamber 11. The drying chamber 11 has an inlet 101 and an outlet 102 on its two side walls. A fan 12 is installed at the top of the drying chamber 11. The drying chamber 11 is equipped with a guide mechanism that reverses the direction of the graphene film passing through it. The guide mechanism causes the graphene film to be wavy, vertical, and horizontal in sequence in the drying chamber 11. The drying chamber 11 is also equipped with a drying mechanism that treats the surface moisture of the graphene film.

[0027] In this embodiment, the guiding mechanism includes a first support roller 21, a second support roller 22, a third support roller 23, and a fourth support roller 24 that are sequentially rotated inside the drying chamber 11. The first support roller 21 is close to the feed inlet 101. The first support roller 21, the second support roller 22, and the third support roller 23 provide wavy support to the graphene film, while the third support roller 23 and the fourth support roller 24 provide vertical support to the graphene film.

[0028] In this embodiment, the drying mechanism includes a cleaning component disposed in the upward region of the wavy section of the graphene film, and a processing component disposed in the vertical section of the graphene film.

[0029] The cleaning component includes connecting pipes 312 disposed on the upper and lower sides of the graphene film in the wavy section. The rear end of the connecting pipes 312 passes through the drying chamber 11 and is connected to a drying air source. The lower end of the connecting pipes 312 is connected to a flat nozzle 313, which is inclined towards the middle. The gas blown out crosses the surface of the graphene film it passes over. When the graphene film moves from the first support roller 21 to the second support roller 22, the gas in the connecting pipes 312 is sprayed out through the flat nozzles 313, blowing off the moisture on the upper and lower surfaces of the graphene film, thus performing preliminary treatment on the moisture of the graphene film.

[0030] The processing component includes rotating tubes 31 arranged on both sides of the vertical section of the graphene film. The rotating tubes 31 are rotatably mounted on the drying chamber 11, and their rear ends pass through the drying chamber 11 and are connected to a drying air source. An arc-shaped plate 32 is provided on the rotating tubes 31 in the drying chamber 11. Nozzles 33 are evenly distributed on the opposite surface of the arc-shaped plate 32. A cavity communicating with the rotating tubes 31 is provided inside the arc-shaped plate 32. A power component is provided at the front end of the rotating tubes 31 to make the rotating tubes 31 reciprocate intermittently.

[0031] The power assembly includes a transmission gear 34 fixed to the front end of the rotating tube 31, the transmission gears 34 meshing with each other. A support shaft 37 is fixed to the front wall of the drying chamber 11, and a sector gear 35 is provided on the support shaft 37, meshing with one of the transmission gears 34. A swing plate 36 is fixed to the front end of the sector gear 35, and a sliding groove is provided on the swing plate 36. A mounting base 38 is fixed on the side of the drying chamber 11 away from the transmission gear 34 of the sector gear 35. A motor 39 is mounted on the side wall of the mounting base 38, and a rotating disk 310 is fixed on the output shaft of the motor 39. A transmission boss 311 is provided on the rear end face of the rotating disk 310, and the transmission boss 311 cooperates with the sliding groove on the swing plate 36. The swing plate 36 and the rotating tube 31 are in the same water. On the plane, the transmission boss 311 is slidably connected to the groove of the swing plate 36; the swing plate 36 is fixed as a whole with the sector gear 35, and the sector gear 35 and the swing plate 36 are rotatably connected to the support shaft 37; the motor 39 drives the rotating disk 310 and the transmission boss 311 to rotate. During the rotation of the transmission boss 311, it cooperates with the groove of the swing plate 36, so that the swing plate 36 and the sector gear 35 swing and rotate intermittently. The sector gear 35 meshes and rotates with one of the transmission gears 34, and through the meshing rotation between the transmission gears 34, it drives the arc plate 32 and the nozzle 33 on the rotating tube 31 to rotate intermittently, so that the nozzle 33 dries the graphene film passing through in different directions.

[0032] The working principle and usage process of this utility model are as follows: The graphene film is routed around the first support roller 21, the second support roller 22, the third support roller 23, and the fourth support roller 24 inside the drying chamber 11. The first support roller 21, the second support roller 22, and the third support roller 23 provide wavy support for the graphene film, while the third support roller 23 and the fourth support roller 24 provide vertical support. The drying gas source in the rotating tube 31 and the connecting tube 312 is connected. As the graphene film moves from the first support roller 21 to the second support roller 22, the gas in the connecting tube 312 is sprayed out through the flat nozzle 313, removing moisture from the upper and lower surfaces of the graphene film. As the graphene film moves from the third support roller 23 to the fourth support roller 24, the motor 39 drives the rotating disk 310 and the transmission boss 311 to rotate. During the rotation of the transmission boss 311, it cooperates with the sliding groove of the swing plate 36, causing the swing plate 36 and the sector gear 35 to swing and rotate intermittently. The sector gear 35 meshes with one of the transmission gears 34 and rotates. Through the meshing rotation between the transmission gears 34, the arc plate 32 and the nozzle 33 on the rotating tube 31 are driven to rotate intermittently, so that the nozzle 33 dries the graphene film in different directions, thereby improving the drying efficiency of the graphene film.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
