Automatic energy-saving control pipeline for dust removal of press

The automatic energy-saving control pipeline comprises a dust collection hose and a gate valve on the dust collection hose, the dust collection hose is connected to the top of a skip car hopper, the skip car hopper is connected with a micro-powder crusher through a discharging pipe, and a weight sensor is installed at the bottom of the skip car hopper. The weight sensor is electrically connected with the input end of the controller, the output end of the controller is electrically connected with the micro-powder crusher and the gate valve, when the weight sensor detects that the skip hopper is full of materials, the controller controls the micro-powder crusher to stop working, at the moment, the skip hopper does not need to raise dust or collect dust, and therefore the gate valve is controlled to be closed; when the skip car hopper lacks materials, the controller controls the micro-powder crusher to start, the powder is discharged through the discharging pipe, the controller controls the gate valve to open an
