The invention belongs to the technical field of photovoltaic manufacturing industry, and particularly relates to a disc-type
silicon carbide shaping
machine based on a planetary
gear train. The disc-type
silicon carbide shaping
machine comprises a support frame, a top beam, a first rotating shaft, a second rotating shaft, a connecting part, a first gear, a second gear, a gear ring, a rolling disc, a shaping disc, a material collecting frame, a support plate, a
hollow cylinder, a feeding frame, a third rotating shaft, a spiral plate, a first motor, a second motor and a third motor. According to the disc-type
silicon carbide shaping device, the spiral plate can bring
silicon carbide in the feeding frame to the shaping disc by starting the third motor; the first motor is started to enable the
grinding disc to rotationally rub and shape the
silicon carbide on the shaping disc, so that edges and corners of the
silicon carbide are polished to be smooth, the silicon carbide is shaped into spherical particles, and the shaping effect of the shaping
machine is improved; and then the second motor is started to drive the shaping disc to rotate, the silicon carbide on the shaping disc can move outwards along a vortex-shaped groove and is automatically discharged into the material collecting frame, so that
automation of the shaping machine is achieved.
