The scrapers 711 clean the metal powder adhering to the inner wall of the mixing tank 2 and continuously mix it with the metal powder inside the mixing tank 2, thereby improving the mixing effect of the device on the metal powder. Since the diameters of the third cone pulley 706 and the fourth cone pulley 708 are smaller than the diameters of the second cone pulley 704 and the first cone pulley, the rotation speed of the fourth cone pulley 708 is greater than the rotation speed of the first cone pulley, which helps to increase the rotation speed of the second rotating shaft 709 and the mixing blades 712, preventing the metal powder from accumulating at the bottom side inside the mixing tank 2 due to gravity, and thus improving the mixing effect of the metal powder at the bottom side inside the mixing tank 2.

[0033] Working principle: When in use, the external metal powder is conveyed into the interior of the mixing tank 2 through the feed port. At the same time, the first motor 5 and the second motor 703 are started. The second motor 703 drives the first rotating shaft 702 and the first cone pulley to rotate. By utilizing the linkage effect between the first cone pulley and the second cone pulley 704, the power is transmitted to the second cone pulley 704, causing the second cone pulley 704 to drive the third cone pulley 706, the fourth cone pulley 708 and the second rotating shaft 709 to rotate. As a result, the second rotating shaft 709 and the first rotating shaft 702 drive the mixing blades 712, the connecting sleeve, the connecting rod 710 and the scraping plate 711 to rotate. The metal powder inside the mixing tank 2 is mixed by the mixing blades 712, and the scraping plate 711 cleans the metal powder adhering to the inner wall of the mixing tank 2 and continuously mixes with the metal powder inside the mixing tank 2. Since the diameters of the third cone pulley 706 and the fourth cone pulley 708 are smaller than those of the second cone pulley 704 and the first cone pulley, the rotation speed of the fourth cone pulley 708 is greater than that of the first cone pulley, which helps to increase the rotation speed of the second rotating shaft 709 and the mixing blades 712, so as to improve the mixing effect of the metal powder at the bottom side inside the mixing tank 2. At the same time, the first motor 5 drives the connecting shaft 3 and the mixing tank 2 to swing within a certain angle range, which helps to improve the mixing effect of the metal powder inside the mixing tank 2. During the rotation of the connecting shaft 3, the convex block 401 is driven to rotate. During the rotation of the convex block 401, the sliding plate 402, the airbag 403 and the spring 405 are squeezed, and the gas inside the airbag 403 is conveyed into the interior of the first cavity 408 through the air outlet pipe 406, and then sprayed into the inner cavity 6 through the connecting cavity 409, the air outlet frame 410 and the air outlet 411, which helps to increase the air flow inside the mixing tank 2, so as to improve the cooling effect of the device during the mixing process.
