Abstract

The invention provides an unloading powder laying mechanism on 3D printing equipment, and belongs to the technical field of 3D printing systems. The unloading powder laying mechanism comprises a mounting base, wherein a base table is fixedly connected to the left side of the mounting base, a rotating shaft is rotationally connected to the inner side of the base table, a core shaft is inserted into the left side of the rotating shaft, a powder spreading arm is fixedly connected to the outer side of the core shaft, and the outer side of the bottom of the powder laying arm is fixedly connected with a clamping cutter. The problems that a core transmission module is damaged due to the occurrence of conditions during the powder laying action of equipment, laser still has the sintering risk when a powder laying mechanism is damaged, and maintenance and replacement are troublesome due to the fact that the core shaft and the rotating shaft are connected through screws are solved. According to the invention, the load borne by a powder laying knife exceeds a preset value, when an unloading protection action occurs, the rotating shaft shields a proximity probe, and the proximity probe outputs an alarm signal to a host, so that the transmission module can be effectively prevented from being damaged, troubleshooting work is facilitated, and an effective prevention and protection effect is achieved in allusion to sudden and abnormal conditions.

Description

Technical field: [0001] The invention belongs to the technical field of 3D printing systems, and in particular relates to an unloading powder spreading mechanism on 3D printing equipment. Background technique: [0002] The powder spreading mechanism is the core part of metal 3D printing for the supply of powder raw materials. During the movement of the equipment, the horizontal movement of the powder spreading knife drives the powder raw materials into the molding cylinder, which is the basic and final input link in the printing process. [0003] However, during the daily operation of equipment, when the equipment is spreading powder, with the piston protruding from the working plane or the parts are cheap, or the support is sintered and separated from the substrate, the powder spreading knife will have hard collision or high load friction or impact of the lifting cylinder. and other problems, the series of phenomena described above will cause damage to the core transmission...
