Description

Powder supply unit of additive manufacturing equipment and additive manufacturing equipment Technical Field The utility model relates to the field of additive manufacturing, in particular to a powder supply unit of additive manufacturing equipment and the additive manufacturing equipment comprising the powder supply unit. Background The additive manufacturing technology, namely the 3D printing technology, is widely applied by virtue of the advantages of free forming, high material utilization rate and the like. Powder raw material is one of the main raw materials for additive manufacturing, which is laid down on a printing plane during printing. The agglomeration phenomenon of the powder raw materials is easy to occur, which can lead to uneven powder spreading and seriously affect the molding precision and quality. Disclosure of utility model The object of the present utility model is to provide a powder supply unit of an additive manufacturing apparatus which facilitates reducing agglomeration of powder raw materials. It is a further object of the present utility model to provide an additive manufacturing apparatus that facilitates reducing agglomeration of powder raw materials. The utility model provides a powder supply unit of additive manufacturing equipment, which comprises a hopper and a turnover module. The hopper is provided with a discharge chute for containing powder raw materials and a discharge hole is formed in one side of the discharge chute. The turnover module is rotatably arranged on the discharging chute around the first axis. The overturning module is provided with a powder stirring piece and a depolymerizing piece. The powder stirring piece can stir the powder raw materials in the discharge chute out of the discharge chute through the discharge hole by rotating. The deagglomeration is a plate-like member having holes or slits and is capable of breaking up agglomerates of powder raw material passing therethrough. The powder supply unit of the additive manufacturing equipment is beneficial to the depolymerization of the aggregate of the powder raw materials by arranging the depolymerization piece, thereby being beneficial to improving the additive manufacturing quality. In another exemplary embodiment of the powder supply unit of the additive manufacturing apparatus, the discharge chute is cylindrical with a circular segment in cross section, and a chord of the circular segment is provided as the discharge opening of the discharge chute. The first axis coincides with the axis of the spout. The depolymerization member penetrates the spout along the first axis and extends radially outward from the first axis to be able to separate portions of the spout located in the spout, located on both sides of the depolymerization member in the circumferential direction. In this way, the deagglomeration member is able to break up agglomerates of powder raw material more fully during rotation. In a further exemplary embodiment of the powder supply unit of the additive manufacturing apparatus, the powder stirring member penetrates the discharge chute along the first axis and extends radially outward from the first axis to be able to divide the portions of the discharge chute located in the discharge chute located on both sides of the powder stirring member in the circumferential direction. Thus, the powder stirring efficiency is improved. In a further exemplary embodiment of the powder supply unit of the additive manufacturing apparatus, the deaggregation piece and the powder stirring piece can enclose a post-treatment space with the wall of the discharge chute on the rear side of the deaggregation piece in the first direction of rotation of the tilting module. Therefore, the powder raw material pushed back to the discharge chute from the discharge hole is prevented from being pulled out again by the powder pulling piece for powder paving without depolymerizing treatment of the depolymerization piece. In a further exemplary embodiment of the powder supply unit of the additive manufacturing apparatus, the deagglomeration member comprises a plurality of bars arranged at intervals. The front edge of the strip body along the first rotating direction is gradually thinned to be wedge-shaped. This facilitates more efficient breaking up of agglomerates of powder material. In a further exemplary embodiment of the powder supply unit of the additive manufacturing apparatus, the hopper further has a preparation chamber. The discharge chute is communicated with the material preparing cavity. The powder supply unit also comprises a powder feeding roller. The powder feeding roller is rotatably arranged at the communication part of the discharge chute and the material preparation cavity. The surface of the powder feeding roller is concavely provided with a powder feeding groove. The powder feeding roller can enable the powder feeding groove to enter and exit the material preparation cavity and the discharging groove thro
