[0024] As shown in Figures 1-5The flip door 4 is installed at the feeding port of the feeding box 3, and is used for sealing the feeding box 3. When the carbon fibers are cut, the feeding box 3 can be closed by the flip door 4 to prevent dust from overflowing from the feeding port to the surrounding environment. The collecting cover 205 is installed at the upper end of the inner cavity of the feeding box 3, and the filter screen 209 is fixed in the inner cavity of the collecting cover 205. The aperture of the filter screen 209 is smaller than the particle size of the carbon fiber particles. When the dust is generated during the operation of the crusher 1, the dust can rise to the upper part of the feeding box 3, and the collecting cover 205 can collect the dust. The filter screen 209 can intercept the larger carbon fiber particles to prevent the larger carbon fiber particles from entering the subsequent components of the dust collection assembly 2 to cause blockage, and ensure the stable operation of the dust collection assembly 2. The communication pipe 204 communicates the collecting cover 205 with the collecting tank 201, so that the dust collected by the collecting cover 205 can enter the collecting tank 201 through the communication pipe 204. The conical baffle 207 and the filter core 208 are installed in the collecting tank 201. The conical baffle 207 is fixedly connected with the inner wall of the collecting tank 201, and the filter core 208 is fixed at the upper end of the inner cavity of the collecting tank 201. When the dust enters the collecting tank 201, the conical baffle 207 can change the movement direction of the dust, so that part of the larger dust particles falls under the action of gravity. The filter core 208 further filters the fine dust particles to improve the dust removal effect. The vortex fan 202 communicates with the inner cavity of the collecting tank 201 through the suction pipe 203. The vortex fan 202 generates suction force when working, and sucks the dust in the feeding box 3 into the collecting tank 201 through the collecting cover 205 and the communication pipe 204 to provide power for the collection of the dust. After being filtered by the conical baffle 207 and the filter core 208, the settled dust particles fall into the collecting hopper 206. The collected dust can be cleaned regularly by opening the discharge valve, and is convenient for recycling and processing. Through the sealing of the flip door 4 and the effective collection of the dust collection assembly 2, the dust generated in the cutting process of the carbon fibers can be significantly reduced, and the problems that the dust threatens the health of the operators and pollutes the surrounding environment are solved.

[0025] Embodiment 2

[0026] Refer to Figures 1-5 For the second embodiment of the utility model, the embodiment is based on the previous embodiment.
