[0059] Blow the melted or vaporized metal through the high-pressure gas coaxial with the light beam, so that the melted or vaporized metal falls on the material guiding baffle 4. Start the first motor 17 to drive the ball screw 18 to rotate. The ball screw 18 drives the two nuts 19 to move horizontally towards each other. The nut 19 drives the traction rod 20 to deflect. The traction rod 20 drives the moving scraper 11 to move vertically downward on the guiding slide rail 10, so as to scrape the melted or vaporized metal on the material guiding baffle 4, so that the melted or vaporized metal enters the discharge cavity 5 through the discharge groove 3;

[0060] Start the second motor 21 to drive the rotating shaft 22 to rotate. The rotating shaft 22 drives the contact cam 24 to rotate. The rotating contact cam 24 squeezes the discharge plate 23 to move horizontally. Under the elastic force of the second spring 27, the discharge plate 23 is always in movable contact with the contact cam 24, so that the discharge plate 23 pushes the melted or vaporized metal, and the melted or vaporized metal enters the collection box 9, thereby completing the collection operation of the melted or vaporized metal.
