[0002] 3D printing is a manufacturing technology that creates three-dimensional objects by stacking materials layer by layer. Specifically, 3D printing is to design the shape and structure of an object in a computer based on a digital model, then break it down into many thin layers, and build the object layer by layer by stacking or solidifying materials. Polishing equipment is required when processing 3D printed parts.

[0003] After searching, a 3D printing parts polishing equipment with announcement number CN206287012U includes a fixed seat, a connecting plate is connected to the top of the support column, an electric telescopic rod is connected to one side of the support column, a semicircular suction cup is connected to one side of the electric telescopic rod, the top and bottom of the outer side of the semicircular suction cup are provided with interfaces, one side of the interface is connected to a dust suction pipe, the top of the dust suction pipe is connected to a dust collection hose, one side of the dust collection hose is connected to a suction fan, the outlet of the suction fan is connected to a dust collection box, a driven wheel is provided on the top of the sanding belt, a driving wheel is provided on the bottom of the sanding belt, a rotating shaft is connected to the left side of the driving wheel, a motor is connected to the left side of the reducer, a rotating shaft is connected through the middle of the driven wheel, and a dust cover is provided on the top of the driven wheel. This 3D printing parts polishing equipment solves the problem that the dust cleaning is not thorough enough, which will reduce the practicality of the polishing equipment;

[0004] Based on the above patent, by using a driving wheel and a driven wheel, the driving wheel can drive the driven wheel to rotate through the sanding belt when it rotates, so that the sanding belt is used to polish the parts. By using a semicircular suction cup, when the parts are polished by the sanding belt, the semicircular suction cup can absorb the dust generated when the parts are polished, thereby preventing the dust from affecting the polishing effect of the parts. By using an electric telescopic rod and a semicircular suction cup, when the parts are polished, the electric telescopic rod can drive the semicircular suction cup to move, so that the two semicircular suction cups are close to each other, so that the semicircular suction cup can completely absorb the dust. By using a dust cover, the dust generated when the parts are polished will impact upward, so that the dust cover can prevent the dust from being discharged from the driven wheel, thereby improving the dust cleaning effect. However, during processing, only one side can be polished at a time. When the other side needs to be polished, it needs to be removed and re-fixed and then polished, thereby reducing work efficiency.
