SLM equipment feeding device of functional gradient structure and operation method of SLM equipment feeding device

According to the SLM equipment feeding device of the functional gradient structure and the operation method of the SLM equipment feeding device of the functional gradient structure, an electric control technology and a control system are used for controlling a motor, an electromagnetic valve and a telescopic connector assembly to complete corresponding operation, and replacement and filling of powder of a next gradient layer are rapidly and automatically completed; the electrically-controlled telescopic connector assembly is adopted for butt joint of the powder recycling opening and the filler connecting opening, the phenomenon that in the rotating process of replacing a filler pipe, adhesive powder on a pipe opening overflows to pollute a fixed disc can be avoided, and the problems that when a single filler connecting pipe of existing SLM equipment is used for preparing a functional gradient structure, gradient layer powder feeding is difficult, and the production efficiency is high are solved. The device so
