The conductive plate 45 is electrified, the conveying plate 4 continues to drive the metal bar to move right, at this time, the conductive block 43 enters the conductive groove of the electrified conductive plate 45, at this time, the conveying plate 4 is electrified and magnetic, and then the conveying plate 4 adsorbs the metal bar in the placing groove 41, so that dislocation of the aligned metal bar in the conveying process is avoided, and the alignment precision of the metal bar and the hydraulic machine when moving to the hydraulic machine is improved.
Referring to fig. 6, 8 and 10, in order to avoid blocking the metal bar inside the blanking box 52 caused by the metal bar falling faster in the blanking box 52, the arc plate 523 provided by the invention can lock the blanking roller 542 in real time through the mutual matching of the second locking tooth 525 and the first locking tooth 524, so as to avoid the possibility that the metal bar still falls continuously when the inside of the blanking box 52 is blocked, specifically, the left side wall of the blanking box 52 is fixedly provided with a locking rack 521 above the abdicating groove 541, the lower end surface of the locking rack 521 is provided with the arc plate 523 through the connecting spring rod 522, the arc surface of the arc plate 523 is provided with two groups of first locking teeth 524 which are symmetrical front and back, and the circumference surface of the blanking roller 542 is provided with the second locking tooth 525 matched with the first locking teeth 524.
The left end face of the arc plate 523 is provided with a linkage frame 526, a bearing plate 527 sliding up and down is limited below the left side wall of the discharging box 52, a traction rope II 528 is jointly installed between the bearing plate 527 and the linkage frame 526, and a guide block 529 which is matched with the discharging opening 53 and is convenient for releasing the metal bar is arranged on the lower bottom surface inside the discharging box 52.
When the metal bars drop on the supporting plate 527 one by one, the supporting plate 527 can play a role in damping the metal bars through the mutual cooperation of the second traction rope 528, the linkage frame 526 and the arc plate 523 and the connecting spring rod 522, so that the metal bars are prevented from directly falling on the bottom of the blanking box 52 to damage the metal bars, the protection effect is achieved on the metal bars, and meanwhile, the noise of collision between the metal bars and the bottom of the blanking box 52 can be reduced.
Because the toggle plate 32 drives the metal bar to reciprocate left and right on the conveying belt 3, the metal bar is blocked at the blanking opening 53, at this time, the metal bar continuously falls in the blanking box 52 and is piled up on the support plate 527, when the support plate 527 reaches the maximum weight born by the support plate 527, the support plate 527 drives the arc plate 523 to move downwards through the mutual cooperation of the second traction rope 528 and the linkage plate 545, and then the first locking tooth 524 and the second locking tooth 525 on the arc plate 523 mutually cooperate, so that the blanking roller 542 does not rotate any more, the blanking roller 542 does not drive the toggle rod 543 to rotate any more, and at this time, the metal bar is no longer blanked.
When the metal bars on the conveyor belt 3 are placed on the conveying plate 4 one by one, the metal bars at the blanking opening 53 are not blocked any more, the metal bars at the blanking opening 53 roll out from the blanking box 52 after passing through the guide blocks 529 in order, the connecting spring rods 522 reset to drive the arc plates 523 to move upwards, the first locking teeth 524 and the second locking teeth 525 are separated from each other, the blanking rollers 542 are released from limit, if the metal bars are arranged on the linkage plate 545, the next metal bar falling step is repeated, the rest metal bars can be processed one by one, and if the metal bars are not arranged on the linkage plate 545, the rest metal bars can be processed one by repeating the first metal bar falling step.
The working principle of the invention is as follows: the first step: the metal bars are thrown into the blanking box 52 one by one from the upper part of the blanking box 52 through the existing small-sized hoisting machine, at the moment, the lowest metal bar is positioned between two poking rods 543 in the blanking box 52, at the moment, the manual poking-down linkage plate 545 gives a driving force for downwards moving the locking rods 548 through the first hauling ropes 540, the locking rods 548 downwards move away from the corresponding locking grooves 546, and the blanking rollers 542 are released from limit.
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.
