[0029] In the specific implementation process, after adding the material to be foamed and the additives conducive to foaming into the foaming box 8, the carbon dioxide bottle assembly 2 is adjusted to pressurize the carbon dioxide in the carbon dioxide bottle assembly 2. When the pressure is increased to a suitable pressure, the carbon dioxide bottle assembly 2 and the heating assembly 3 are turned on to rotate the assembly 5. The rotating assembly 5 rotates and under the action of the transmission assembly 4, some structures in the heating assembly 3 and the stirring assembly 6 are in working state. The pressurized carbon dioxide in the carbon dioxide bottle assembly 2 enters the heating assembly 3. The heating assembly 3 heats the carbon dioxide to a certain temperature.
