Linear cutting waste collecting device

The utility model relates to the technical field of linear cutting, and particularly discloses a linear cutting waste collecting device which comprises a base used for linear cutting, a cutting component arranged on the base, an adjusting component arranged on the base and a cutting area used for cutting a target object. The cutting area is matched with the water collecting box on the base, cooling liquid is collected, in the cooling liquid collecting process, the cooling liquid can be scattered and guided through the flow guiding component, and therefore the use requirement is met, meanwhile, in the flow guiding process, the flow guiding plate body arranged at the preset angle is utilized, and the flow guiding effect is improved. The cooling liquid can smoothly flow into the filter frame, waste residues can be collected in cooperation with the filter screen, meanwhile, the cooling liquid continues to be guided downwards, the cooling liquid can be filtered again through the filter cotton, and therefore the us
