WIPO Patent Application WO/2021/204008

A1

Provided is a grinding machine, comprising: a base (10), a machine body, and a grinding mechanism (30); a grinding cavity (21) is provided in the machine body; the machine body has a material feed inlet (24) and a powder outlet which are respectively connected to the grinding cavity (21); the powder outlet is connected to a powder outlet pipe (25) suspended above the base (10); the grinding machine also comprises a powder ejection mechanism (40); the powder ejection mechanism (40) comprises a powder ejection member and an elastic member (44); the powder ejection member is rotatably connected to the machine body and the elastic member (44) acts on the powder ejection member such that when the external force that keeps the powder ejection member away from the powder outlet pipe (25) is withdrawn, the powder ejection member returns to its position and hits the powder outlet pipe (25). After the grinding is completed, the grinding machine can, if necessary, use the powder ejection mechanism (40) to hit the powder outlet pipe (25), causing the powder adhered to the wall of the powder outlet pipe (25) to be knocked off, achieving the purpose of cleaning the powder outlet pipe (25), and reducing the probability of the powder outlet pipe (25) becoming clogged.
