[0003] For example, a knurling machine for nut production disclosed in the utility model with authorization announcement number CN219212149U has a vertical plate, a hydraulic cylinder and a slide rod. The output end of the hydraulic cylinder drives the second support frame to slide through the slide rod to adjust the distance between the second knurling wheel and the first knurling wheel, thereby facilitating the knurling of nuts of different sizes. However, the existing knurling machine for nut production will generate a large amount of waste chips when knurling the nuts. Since the existing knurling machine itself does not have a structure for waste chip treatment, the waste chips generated during knurling will remain on the surface of the machine body, thereby affecting the subsequent normal knurling of the nuts, and the practicality is not good.
