Guide blade angle adjusting system for powder concentrator

The utility model relates to the technical field of material screening, in particular to a guide blade angle adjusting system for a powder concentrator. A flange is arranged at the lower portion of a stepping motor with a brake disc, and a powder concentrator shell is installed on the flange. A reducer of a transmission gear is arranged at an output end of the stepping motor. A large gear ring supported by a support on the powder concentrator shell is used in cooperation with the transmission gear, the other end of the large gear ring is connected with transmission arms on guide blades, and limiting switches are installed on the powder concentrator shell and distributed on the two sides of the corresponding transmission arm. Displacement sensors are installed on the powder concentrator shell and distributed on one side of the corresponding transmission arm. The guide blade angle adjusting system has the advantages that because an electric actuator is used, the automation degree of angle adjustment of the guide blades of the powder concentrator is greatly increased, and real-time adjustment of the angle of the guide blades is achieved; in this way, the powder screening performance of the powder concentrator is brought into full play, the yield of the powder concentrator is improved, the debugging time of the powder concentrator is greatly shortened, a lot of unnecessary labor costs can be reduced, and therefore the economic benefits of a manufacturing enterprise are increased.
