Paint spraying and drying device for graphene sheet

Abstract

The invention relates to a paint spraying and drying device for a graphene sheet. The device comprises a drying pipe, a branch pipe, a connecting rod mechanism and a scraping frame mechanism, wherein a V-shaped frame is arranged at the top of the drying pipe; two drying frames are arranged at two sides of the top of the V-shaped frame through rotating shafts; spraying holes communicating with the drying pipe are formed in the bottom of the V-shaped frame; and the connecting rod mechanism comprises a crankshaft fixed to the drying pipe through a bearing, and a motor fixed to the outer wall of the drying pipe and used for driving the crankshaft to act. Each of the two drying frames is provided with a row of rotary nozzles, and in the actual use process of the device, the motor where the crankshaft is located is used for driving the two drying frames to move up and down through connecting rods, and the crankshaft is also used for driving racks to drive the spray heads to rotate and swing (not to rotate in the circumferential direction but only to rotate in a reciprocating manner), so that the sprayed gas acts on the graphene sheet more reasonably in a larger range, the purpose of rapid baking is achieved, and the linkage structure is reasonable and ingenious in design.

Description

technical field [0001] The invention relates to the technical field of drying devices, in particular to a graphene plate material spraying and drying device. Background technique [0002] Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery. It is considered to be a revolutionary material in the future. , in order to improve its service life, and according to the needs of the occasion, it is often necessary to spray paint on the surface of the graphene board. [0003] However, when the graphene board is painted, it is difficult to ensure that there is paint residue on the surface. At the same time, the graphene board needs to be dried after painting. The existing drying method is hot air baking method, and the graphene board is laid flat On the tooling rack, use the drying blowing pipe to dry the surface. This drying method has low wo...

[0003] However, when the graphene board is painted, it is difficult to ensure that there is paint residue on the surface. At the same time, the graphene board needs to be dried after painting. The existing drying method is hot air baking method, and the graphene board is laid flat On the tooling rack, use the drying blowing pipe to dry the surface. This drying method has low work efficiency and high labor intensity, and when the graphene board is in an absolutely static state, it will be heated due to concentrated heat. Partial scorching and bluish phenomenon of graphene board affects product quality
