[0037] Working principle:

[0038] Before use, water is introduced into the vibrating water pipe 302 in the atomizing box 301. The vibrating water pipe 302 is spirally arranged in the atomizing box 301. A central column 303 is set at the bottom of the atomizing box 301. Ultrasonic generators 304 are set on the inner wall of the atomizing box 301 and the surface of the central column 303. Multiple ultrasonic generators 304 are spirally arrayed in the direction of the axis of the vibrating water pipe 302. Water mist enters two atomizing nozzles 3 from the top of the atomizing box 301 through the connecting pipe. The surface of the atomizing nozzles 3 is fixedly connected to the surface of the cutting bracket 201. The surface of the cutting bracket 201 is elastically connected to the surface of the intermittent baffle 305 through the return spring 307. The surface of the intermittent baffle 305 is slidably connected to the surface of the cutting bracket 201 through the guide rod 306. The return spring 307 is located outside the guide rod 306. The surface of the worktable 1 is equipped with the cutting bracket 201. The cutting motor 202 on the cutting bracket 201 drives the cutting roller 2 on the surface of the cutting bracket 201. The cutting roller 2 is rotated, and its surface is respectively provided with connecting blocks 206, circular blades 207 and triangular blades 208. The connecting blocks 206 and triangular blades 208 are arranged in a circumferential array on the surface of the cutting roller 2. Multiple connecting blocks 206 are sequentially slidably connected to the surface of the intermittent baffle 305, causing the surface of the intermittent baffle 305 to slide along the surface of the cutting bracket 201. The surface of the intermittent baffle 305 is slidably connected to the surface of the atomizing nozzle 3, intermittently controlling the spray range of the atomizing nozzle 3 so that the water mist always falls on the surface of the circular blades 207 and triangular blades 208. The surface water mist affects the product quality. Above the worktable 1, there are also guide rollers 203 and winding rollers 204. The product cut off by the cutting roller 2 is conveyed on the surface of the worktable 1. The scraps of the cut product are wound onto the surface of the winding roller 204 through the surface of the guide roller 203. The winding motor 205 on the surface of the worktable 1 drives the winding roller 204 to rotate on the surface of the worktable 1 to collect the cut scraps.
