[0029] In order to facilitate the understanding of the above technical scheme of the utility model, the working principle or operation mode of the utility model in the actual process will be described in detail as follows:

[0030] When it is needed to use the stacker to convey the stack plate to the next process and complete the feeding operation:

[0031] Firstly, the stacked stack plate is transferred to the position between the two groups of moving platforms 1 and bases 8 by using the conveyor belt or the roller mechanism, and then the initial position of the lifting claw 2 is in the retracted state.

[0032] When it is needed to transfer and convey away the bottommost stack plate (i.e. the tray):

[0033] At the same time, the double-acting cylinder 7 is started, and the double-acting cylinder 7 outputs the first section, and the double-acting cylinder 7 and the first cam 9 drive the second shaft 6 to rotate. At this time, the first shaft 4 and the second shaft 6 are connected by the linkage rod 11, so that the first shaft 4 and the second shaft 6 can rotate synchronously. Since the first shaft 4 and the second shaft 6 are both fixedly connected with the swing arm 5, the swing arm 5 can be deflected upward, so as to cooperate with the roller 501 to lift the moving platform 1 located above. At this time, the moving platform 1 located on both sides of the stack of pallets is just flush with the second pallet (counted from the second from the bottom) in the stack of pallets, and the lifting clamping jaw 2 on the moving platform 1 is just aligned with the hole on the second pallet. At this time, the lifting clamping jaw 2 is driven by the telescopic cylinder 201 to move towards the pallet, so that the sinking platform on the lifting clamping jaw 2 is inserted into the second pallet.

[0034] Then, the double-acting cylinder 7 is started again, and the double-acting cylinder 7 outputs the second section. At this time, since the lifting clamping jaw 2 is inserted into the second pallet, the second pallet and all the pallets above it can be moved upward at the same time under the action of the double-acting cylinder 7 and the swing arm 5, so as to be separated from the bottommost pallet.

[0035] At this time, since the bottommost pallet is not pressed, it can be transported away again by using a conveyor belt or a rotating roller structure until it reaches the next station, thereby completing the feeding operation.

[0036] After that, the double-acting cylinder is completely retracted, the moving platform 1 is completely lowered, and all the pallets are again placed on the conveying mechanism such as a conveyor belt or a rotating roller. Then, the lifting clamping jaw 2 is retracted to the initial state, and the feeding work of the next bottommost pallet can be performed.

[0037] In summary, through the cooperation of the double-acting cylinder 7, the swing arm 5 and the lifting clamping jaw 2, the bottommost pallet of the stack of pallets can be quickly taken out without using manpower. This not only improves the feeding speed of the pallets and reduces the labor intensity of the operators, but also avoids a large number of safety hazards in the operation process.

[0038] Wherein, through the cooperation of the second gear 304, the first gear 303 and the chain, the circumferential rotating force of the second shaft rod 6 can be transmitted to the rotating shaft 301 to drive the rotating shaft 301 to rotate synchronously, and then through the cooperation of the rotating shaft 301 and the connecting shaft 302, the second shaft rod 6 and the first shaft rod 4 located on both sides of the stack board pile can be connected and driven, when the double-stroke cylinder 7 is installed on one side of the base 8, the second shaft rod 6 and the first shaft rod 4 on the other side can be driven to rotate synchronously, so as to realize the feeding work of the stack board, which has the advantages of simple cooperation of components, low cost, but the weight of the stack board is required to be higher, and the carrying capacity is smaller; when the double-stroke cylinder 7 is installed on both sides of the base 8, the double-stroke cylinder 7 on both sides can exert force at the same time, so as to exert force on the two groups of first shaft rod 4 and second shaft rod 6, which has the advantage of high carrying capacity, and is suitable for heavy work and large batch work conditions, but the cost is higher, so the operation can be selected according to the working condition, which has the characteristics of flexibility, high practicality.
