The direction and speed of the drive motor 3 can be flexibly adjusted by an external control device. Flexible cleaning sleeves are provided on the circumferential side walls of the cleaning rollers 4. The flexible cleaning sleeves on the two cleaning rollers 4 are tangentially arranged. In the specific working process, the two flexible cleaning sleeves clean the two surfaces of the graphene film respectively and apply a certain pressure, which can effectively improve the cleaning quality.

[0033] The cleaning device adopts a box-type structure, with spray components, cleaning roller groups, and air jet components arranged sequentially according to the material movement direction. Its compact structure and small footprint make it easy to integrate into existing production lines. The spray components can evenly spray the cleaning solution onto the graphene film surface, ensuring full contact between the cleaning solution and the graphene film, thereby improving cleaning efficiency. The cleaning roller group uses two vertically arranged cleaning rollers 4 for surface cleaning, and the flexible cleaning sleeve design removes stubborn stains from the graphene film, ensuring comprehensive and thorough cleaning. The air jet component effectively blows away residual cleaning solution from the graphene film surface, preventing residual cleaning solution from being carried out of the cleaning device and polluting the surrounding environment.

[0034] like Figure 3-4 As shown, the spray assembly includes: a pair of mounting plates 15 vertically arranged on the left and right side walls of the inner cavity of the housing 1; a plurality of diversion pipes 16 are arranged on the opposite side walls of the mounting plates 15; a nozzle 17 is arranged at the end of the diversion pipe 16; and the mounting plates 15 have internal flow channels that cooperate with the diversion pipes 16.

This arrangement ensures that the cleaning fluid can be evenly sprayed onto the graphene film from both sides, improving the uniformity and coverage of the cleaning. Each diversion pipe 16 has a nozzle 17 at its end. Preferably, the nozzle 17 can be an atomizing nozzle, which disperses the cleaning fluid into fine droplets, increasing the contact area with the graphene film surface. A storage tank 7 is located at the bottom of the housing 1 to store the cleaning fluid. A delivery pump 14 is installed on one side of the storage tank 7 and connected to the mounting plates 15 via a delivery pipe 8, delivering the cleaning fluid from the storage tank 7 to the spray assembly.
