Description

Technical Field

[0001] The present invention specifically relates to the technical field of dust collection for carbon fiber processing, and in particular to a dust collection device for carbon fiber processing. Background Art

[0002] Carbon fiber is a new type of fiber material with high strength and high modulus, with a carbon content of more than 95%. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite crystals along the axial direction of the fiber and undergoing carbonization and graphitization treatment.

[0003] A large amount of carbon fiber dust will be generated during the carbon fiber processing process. The carbon fiber dust is easy to float in the air, affecting the air quality around the working environment. The carbon fiber dust is easy to be inhaled into the lungs of people, affecting people's health. Therefore, dust removal is required in the carbon fiber processing project. The existing dust collection device solution, for example, a carbon fiber sanding machine dust removal device disclosed in CN210596655U, includes a sanding machine body and a feed inlet on the top of the sanding machine body and a cleaning brush inside the sanding machine body. A discharge port is arranged on one side of the feed inlet, a sanding wheel is arranged inside the sanding machine body, and a sanding wheel is arranged inside the sanding machine body. A first motor is arranged on one side, a second motor is arranged below the first motor, a dust box is arranged on the other side of the sanding machine body, a dust collecting box is fixedly installed above the dust box, a limiting roller is arranged inside the sanding machine body, and a dust suction pipe is arranged inside the sanding machine body. With this design, the cleaning brush can avoid the staff from performing secondary processing on the fluff on the surface of the cloth, thereby improving the production efficiency of the cloth. The dust suction pipe can quickly collect the fluff generated by sanding the cloth. However, this design requires both a motor for driving the cleaning brush and a power pump for dust collection, so multiple driving devices are required, which is large in size and has low overall efficiency.

[0004] Therefore, we provide a dust collection device for carbon fiber processing to improve the system design integration and reduce cost and weight. Summary of the invention
