3) the extrusion plates move oppositely by means of the extrusion cylinders to extrude the ton bag, so that a large amount of materials in the ton bag begin to be unloaded from the laser cutting position; after the unloading is basically finished, the extrusion plates start to do the separation movement to loosen the ton bag, the materials in the ton bag fall into the discharge hopper through the vibrating screen, and the ton bag is left on the vibrating screen;
4) after the ton bag is unloaded, the vibration motor is started to drive the vibration screen and the ton bag on the vibration screen to vibrate, so that the residual materials in the ton bag can be shaken down into the discharge hopper;
5) after unloading, stopping the vibrating motor, and stopping vibrating the vibrating screen; the first electric valve is opened, the material in the lower hopper enters the first discharge chute through the discharge port and the first electric valve, falls onto the belt device and is conveyed to the next process, and then the first electric valve is closed;
6) after the vibrating screen stops vibrating, the screen lifting device starts to extend out of the push rod to enable the vibrating screen to incline towards one side of the bag outlet until the vibrating screen contacts the limiting baffle, the waste bag stops sliding into the waste bag bin through the bag outlet under the action of gravity, the waste bag retracts after sliding out of the push rod, and the vibrating screen recovers to the horizontal position under the action of gravity;
7) and (4) regularly opening the electric valve II, and enabling the recovered powder to fall onto a belt device through the discharge chute II by back blowing of the draught fan, and conveying the powder to the next process.
