And a second step of: at this time, the lowermost metal bar drives the blanking roller 542 to rotate by gravity through the poking rod 543 which is abutted against the lowermost metal bar, the blanking roller 542 drives the metal bar to move downwards through the poking rod 543 in the synchronous rotation process, the reset spring 549 stretches, and when the lowermost metal bar is separated from the poking rod 543, the reset spring 549 is matched with the first traction rope 540 through the circular plate so that the linkage plate 545 resets, and the locking rod 548 is inserted into the corresponding locking groove 546.

And a third step of: the falling metal bar is contacted with the linkage plate 545 and drives the linkage plate 545 to rotate by a certain angle in the falling process, when the linkage plate 545 rotates by a certain angle, the linkage plate 545 gives a driving force for the downward movement of the locking rod 548 through the first traction rope 540, the locking plate moves away from the corresponding locking groove 546 downwards, the blanking roller 542 is released from limit, the next metal bar drives the blanking roller 542 to rotate through the poking rod 543 which is abutted against the next metal bar due to gravity, at the moment, the blanking roller 542 synchronously rotates to drive the metal bar to move downwards through the poking rod 543, at the moment, the reset spring 549 stretches, when the metal bar is separated from the poking rod 543, the linkage plate 545 rotates to the maximum rotation angle, the metal bar on the linkage plate 545 rolls onto the conveying belt 3 after falling to the blanking opening 53, and the locking rod 548 is reset due to the fact that the reset spring 549 and the first traction rope 540 are mutually matched, and the locking rod 548 is inserted into the corresponding locking groove 546.

Fourth step: when the metal bar falls on the conveyer belt 3, the conveyer roller 2 is driven to rotate by an external motor, the conveyer roller 2 conveys the metal bar rightwards for a certain distance through the conveyer belt 3 in the rotation process of the conveyer roller 2 and moves to the vicinity of the stirring plate 32, the driving shaft 314 drives the moving plate 311 to reciprocate leftwards and rightwards through the mutual cooperation of the incomplete gear 315, the telescopic spring rod and the driving teeth 313 in the rotation process of the driving shaft 314, the moving plate 311 drives the reciprocating plate 31 to reciprocate leftwards and rightwards through the supporting rod 312 in the left and right reciprocating process of the reciprocating plate 31, the stirring plate 32 is driven to reciprocate leftwards and rightwards, and the metal bar can be stirred to reciprocate leftwards and rightwards in the left and right reciprocating process of the stirring plate 32, so that the metal bar enters the placing groove 41.

Fifth step: the alignment plate 33 can perform front-to-back alignment treatment on the metal bar during the conveying process in the process of reciprocating back and forth.

Sixth step: the conductive plate 45 is electrified, the conveying plate 4 continues to drive the metal bar to move right, at the moment, the conductive block 43 enters the conductive groove of the electrified conductive plate 45, at the moment, the conveying plate 4 is electrified to have magnetism, and then the conveying plate 4 adsorbs the metal bar in the placing groove 41.
