Claim 6:
7. A mixing device adapted for mixing a first material, a second material and a plurality of elastic fillers to form a molding material, said mixing device comprising:
a base including an upper case body, and a lower case body that is coupled to said upper case body and that cooperates with said upper case body to define an accommodating space, said upper case body having a first inlet and a second inlet that communicate with said accommodating space and that are adapted respectively for passage of the first and second materials into said accommodating space therethrough, said lower case body having a third inlet and an outlet that communicate with said accommodating space;
a side tube connected to said third inlet of said lower case body and cooperating with said third inlet for passage of the elastic fillers into said accommodating space therethrough;
a primary extruder screw disposed within said accommodating space and rotatable about a first axis; and
a secondary extruder screw extending through said side tube, rotatable about a second axis that is transverse to the first axis, and adapted for conveying the elastic fillers into said accommodating space;
a transmission seat and a motor connected to said transmission seat, said transmission seat including a transmission shell and a transmission shaft that is disposed within said transmission shell, and that is connected between said motor and said secondary extruder screw, said motor being operable to drive said transmission shaft to rotate to thereby drive said secondary extruder screw to rotate;
a fastening seat connected between said transmission seat and said side tube, and including a fastening shell that defines a feeding space therein and that has a hopper-connecting hole and a tube-connecting hole communicating with said feeding space, said secondary extruder screw extending through said fastening seat, said side tube having opposite ends connected respectively to said third inlet of said lower case body and said tube-connecting hole; and
a feed hopper having a feeding opening that is connected to said hopper-connecting hole of said fastening seat, and adapted for pouring of the elastic fillers into said feeding space of said fastening seat via said feeding opening;
wherein said primary extruder screw is operable for mixing the elastic fillers and a reaction product, which is made by reacting the first material and the second material, in said accommodating space to form the molding material, and extruding the molding material out of said accommodating space via said outlet.
