Efficient building block stacking and bundling device

The utility model discloses an efficient building block stacking and bundling device which comprises a unit stack circulating hanging frame and a packing device. The unit stack circulating hanging frame is hung at the lower portion of an annular rail. The packing device comprises a push mechanism and a stacking and packing platform. The push mechanism is arranged inside the annular rail. The stacking and packing platform is arranged outside the annular rail. Building blocks are transferred, stacked and bundled through the unit stack circulating hanging frame and the packing device, the unit stack circulating hanging frame is hung at the lower portion of the annular rail, the single stack of building blocks are annularly transferred to the stacking and packing platform, a position switch sends out a signal, the unit stack circulating hanging frame stops transferring, an oil cylinder drives the push mechanism to push out the building blocks, the actions are repeated, after three to four stacks of building blocks are pushed out, a bundling machine automatically bundles the building blocks, and the bundled block stacks are conveyed out through a conveying roller. The efficient building block stacking and bundling device is high in bundling speed and stacking efficiency, easy and convenient to operate and capable of lowering the labor intensity of workers.
