The utility model provides a magazine of hacking machine snatchs theory of operation of mechanism as follows:

firstly, a lifting frame 3 in the device is connected with a lifting device, when objects are lifted and stacked, a bearing frame 1 descends from the upper part of the objects, in the descending process of the bearing frame 1, four lifting plates 5 are in contact with the objects, the objects can push the four lifting plates 5 to deflect to a certain degree, when the four lifting plates 5 move to through holes on a tray and partially extend into the through holes, the bearing frame 1 is lifted upwards, at the moment, the bearing frame 1 drives corresponding rotating blocks 4 to move upwards through four bearing rods 2, the rotating blocks 4 drive the lifting plates 5 to have a trend of moving upwards, as the lifting plates 5 extend into the through holes of the tray, the lifting plates 5 rotate to push square sliding rods 15 to move upwards, the square sliding rods 15 move upwards to drive square sliding blocks 16 to move upwards, the square sliding blocks 16 move upwards to compress second springs 17, the square sliding rod 15 moves upwards, the square sliding rod 15 enters the square groove 18, the square groove 18 plays a role in fixing and limiting the square sliding rod 15, the square sliding rod 15 is prevented from rotating until the lifting plate 5 is contacted with the bottom of the rotating block 4, at the moment, the rotating block 4 moves upwards to drive the lifting plate 5 to move upwards, so that the article is lifted, and then the article is moved to a proper position;

when an object is lifted to a proper position, the bearing frame 1 is moved downwards to move the object downwards until the object is contacted with other objects, at the moment, the other objects play a role of supporting the object, so that the bearing frame 1 does not play a role of lifting the object, but the four lifting plates 5 are still positioned in a tray of the object, at the moment, the bearing frame 1 is continuously moved downwards, the lifting plates 5 are rotated, the lifting plates 5 are separated from the rotating blocks 4, at the moment, the second springs 17 release elasticity to push the square sliding blocks 16 to move downwards until the square sliding blocks 16 are contacted with the bottom of the second mounting cavity 14, the square sliding rods 15 are completely moved out of the square grooves 18, then the bearing frame 1 is moved laterally, the lateral movement of the bearing frame 1 can drive the lifting plates 5 to move laterally, until the lifting plates 5 are contacted with one side of the through holes of the tray, at the moment, the lifting plates 5 are not moved, the rotating block 4 rotates, the rotating block 4 rotates to drive the rotating rod 6 to rotate, the rotating rod 6 rotates to drive the rotating disc 8 to rotate, the rotating disc 8 rotates to drive the two fixing rods 9 to rotate, the fixing rods 9 rotate to pull the corresponding first springs 10, the rotating disc 8 rotates to drive the two fixing blocks 11 to rotate at the same time, until the two fixing blocks 11 are contacted with the corresponding second limiting blocks 13, at this time, the lifting plate 5 rotates 90 degrees, the lifting plate 5 is completely moved out of the through hole of the article tray, the bearing frame 1 is continuously moved until the lifting plate 5 is moved to a proper position, when the lifting plate 5 is not in contact with the article tray, the first spring 10 pulls the corresponding fixing rod 9 back far, even if the lifting plate 5 returns to the initial state again, the lifting movement of the whole object is completed, and the palletizing is completed, at this time, the next object can be lifted and moved.

this device is through lifting the cooperation of claw mechanism and elastic mechanism for need not to realize lifting by crane and pile up neatly to snatching of article under the effect of external force, simultaneously through slewing mechanism, can make to lift the separation of board and article tray, thereby realize the function of snatching once more, device mechanical linkage nature is stronger, greatly reduced required energy when snatching article, thereby reduced the loss of the energy.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
