Carbon fiber cloth, as a unidirectional carbon fiber reinforcement product, is usually used for tensile, shear and seismic reinforcement of structural components. Before using carbon fiber cloth, a layer of powdered adhesive is generally sprinkled on the surface of the carbon fiber cloth to reduce the probability of deformation of the carbon fiber cloth in subsequent use. The carbon fiber powdering device, as a device that sprinkles the adhesive on the surface of the carbon fiber cloth, plays an important role in the production and processing of carbon fiber cloth.

[0003] In the prior art, there is a carbon fiber powdering device, which includes a frame, a conveyor belt is arranged on the frame, and the conveyor belt is used to convey the carbon fiber cloth, and the conveying direction of the conveyor belt is the length direction of the frame. A heightening frame is also arranged on the top of the frame, and a powdering mechanism is arranged on the heightening frame, and the powdering mechanism is used to sprinkle the adhesive onto the carbon fiber cloth on the conveyor belt. When in use, the powdering mechanism sprinkles the adhesive onto the conveyor belt, and at the same time, the conveyor belt drives the carbon fiber cloth to move, thereby completing the powdering operation on the carbon fiber cloth.
