that power can be synchronously input from the two ends of the supercharged stirring foaming wheel 4 , thus improving power and reducing the stress on the transmission shaft 5 ; through the rotary stabilizing device 20 , the supercharged stirring foaming wheel 4 rotates more stably ; the supercharged stirring foaming wheel 4 can realize a longer axial length ; the supercharged stirring foaming wheel 4 can also be made into multiple axial flow impellers that are separate in the axial direction ; during installation , the impellers are installed together on the transmission shaft , with one staying close to the other . the foam material generator of this embodiment has all functions of the major structure ; the supercharged stirring foaming wheel 4 can rotate more stably , and realize a longer axial length , thus improving the mixing effect of the melt and the gas , and improving the foaming effect ; the transmission device 2 can be kept away from the housing cavity 3 , thus providing larger space for thermal insulation , and better realizing thermal insulation . working principles , application method and using effects : when the foam material generator of the present invention is in use , the transmission device drives the supercharged stirring foaming wheel 4 to rotate , generally with a common rotational speed ; the to - be - foamed material is melted into a melt through various methods ; before the melt is supplied , a high temperature gas is injected through the housing cavity inlet 7 to heat the foam material generator ; the melt and the high temperature gas are supplied synchronously ; through the rotation of the supercharged stirring foaming wheel 4 , the high temperature gas and the to - be - foamed material melt are automatically sucked into the housing cavity 3 through the housing cavity inlet 7 ; the supercharged stirring foaming wheel 4 beats the gas into tiny bubble particles , and the high - speed rotation of the supercharged stirring foaming wheel 4 stretches and stirs the melt ; the gas and the melt are mixed and stirred in the housing cavity 3 to form foams ; the foams axially moves towards the housing cavity outlet 8 under the supercharging action of the supercharged stirrers 6 , and are extruded from the eddy current grinding foaming cavity 12 ; they are further ground , foamed and filtered in the eddy current grinding foaming cavity 12 to form foams with fine bubbles and uniform size and arrangement ; the foams are eventually discharged through the housing cavity outlet 8 ; an eddy current is formed in the eddy current grinding foaming cavity 12 ; with relative movement , points in the eddy current have an interaction force with each other ; fluid molecules in the eddy current have mutual friction , and a rolling friction force is produced ; through the eddy current , the bonded molecules or atoms are separated ; the particles in the eddy current respectively form a self - moving individual with varying moving speed , and are gradually mixed in the eddy current ; the eddy current stretches the melt , and separates the gas into tiny bubble particles ; the bubble particles are uniformly distributed in the melt , thus forming foams with uniformly distributed bubble particles ; the eddy current grinding foaming disc 11 and the annular grinding disc 9 form a grinding action that uniformly grinds and mixes the melt and the gas . the melt can be stretched into fibres or thin films with multiple singe molecules or atoms connected ; the fibres or thin films are interconnected to form foams with bubbles ; the wall of the bubbles can be a very thin wall or even be made into a thin film with single molecules or atoms connected . the needed foam material is formed after the foams are cooled and solidified ; the foam material can be directly press - rolled , cast and blow - cast , or be made into foam material ingots ; it can be rolled into sections by a rolling mill by double heating ; annealing can be realized , and material strength can be improved . the foam material generator can greatly improve the foaming efficiency , foaming effect and foaming and foam expansion ratio ; various foam expansion ratios can be realized , and the foam expansion ratio can be regulated simply by regulating the supply quantity ratio of the gas and the melt . a high temperature gas is needed to the production of the foam material . a normal temperature gas will largely affect the foaming process ; the high temperature melt may rapidly become viscous in the foam material generator , thus affecting the foaming effect ; even worse , the equipment may fail , and a shutdown accident may happen . after the foam material generator finishes its work , the high temperature gas is continuously input till remaining foams are all discharged out of the foam material generator . the foam material generator will continuously rotate before it is completely cooled . the foam material generator can produce various foam materials , such as glass , ceramic , steel , alloy , plastic and rubber foam materials . these foam materials have a uniform foam structure . the

gas and the material melt are fed into the foam material generator together . the high temperature material melt can be fed into the foam material generator by means of gravity , and the high temperature gas is sucked into the foam material generator . the material melt and the high temperature gas are rapidly mixed and foamed in the foam material generator . when the supply quantity of the high temperature gas and the fluidity and supply quantity of the melt are constant , the bubbles can be more uniform and finer , and the finished foam material can be better if the foam material generator has higher rotational speed and the supercharged stirring foaming wheel 4 has larger diameter . the foam material generator can also be combined with 3d printing technology to directly print various objects . glass foam materials can be used to make all kinds of furniture ; dies can directly be used to make furniture , doors and windows , etc . ; the glass foam materials can also be used
