Injection raw material mixing device

The utility model discloses an injection raw material mixing device and relates to the technical field of mixing devices. Comprising a sealing tank, a plurality of feeding openings are fixedly formed in the upper surface of the sealing tank at equal intervals, and an auxiliary rotating shaft is rotationally mounted in the center of the upper surface of the sealing tank. A second motor drives a single gear to rotate, the single gear drives a main gear to rotate intermittently, a feeding cover at the bottom of a raw material inlet pipe abuts against the bottom wall of a limiting groove, when a sealing cover on the bottom wall of the limiting groove moves to the bottom of the raw material inlet pipe, injection raw materials extrude the sealing cover through the feeding cover, and the sealing cover moves downwards; injection raw materials enter the sealing tank, when the main gear rotates again, the feeding cover abuts against the bottom wall of the limiting groove, the feeding cover is closed, the spring on the
