step S1015: referring to fig. 5 in conjunction with fig. 1, the push plate 42 of the pushing mechanism 40 moves from one side of the channel formed by the two clamping jaws 30 to the other side of the channel, and the push plate 42 moves to push the uppermost material plate 50 out of the accommodating space;

step S1016: the push plate 42 is retracted to the initial position to prepare for the next push; the connecting rods 302 of the two clamping jaws 30 move to the bottom area of the support frame 10 along the vertical section of the guide hole 3031 under the driving of the air cylinder, and then are separated from each other along the horizontal section of the guide hole 3031, and the two connecting rods 302 carry the jaw plates 301 to return to the initial position to prepare for next separation of the material plates 50;

step S1017: the loading frame 22 moves from the current position to the top area of the supporting frame 10, and after the plurality of material plates 50 are lifted to the preset height, the loading frame 22 stops moving; at this point, the uppermost material sheet 50 of the plurality of material sheets 50 enters the channel formed by the two jaws 30;

and repeating the steps S1013 to S1017, until all the material plates 50 are pushed out of the accommodating space by the push plate 42, the loading frame 22 retracts to the bottom area of the supporting frame 10, the push plate 42 retracts to the initial position, and the two clamping jaws 30 of the clamping jaw mechanism retract to the initial position.

To sum up, the embodiment of the utility model provides a technical scheme can promote the polylith material board of waiting to transport to a take the altitude through hoist mechanism, can separate two adjacent material boards and material board through clamping jaw mechanism, and rethread push mechanism is with material board propelling movement. Two adjacent material boards are separated through the clamping jaw mechanism, so that friction can be effectively prevented from occurring between the material board on the upper layer and the material board on the adjacent lower layer when the material boards on the upper layer are transmitted, and one-to-one transmission of the multiple material boards can be completed through the matching operation of the lifting mechanism, the clamping jaw mechanism and the pushing mechanism, so that the energy loss during transmission is reduced, the friction loss of the material boards is reduced, and the generation of dust is reduced simultaneously. The problem of the lifting machine when the promotion and the transmission of the softer raw and other materials of material, the frictional force between raw and other materials is great, can lead to the loss of raw and other materials to and because the dust that raw and other materials friction produced is in the consumption of the energy and to the pollution of environment two aspects, all very unfavorable to enterprise and staff is solved.
