[0003] A search revealed a Chinese utility model patent with publication number CN214988741U, titled "PC fully automatic palletizer." The patent comprises two left and right crawler conveyors capable of forward and reverse motion. The crawler conveyors are topped with fixed columns, with two front and rear crossbeams and an intermediate beam positioned between the fixed columns. The intermediate beam is positioned between the two crossbeams, with a left fixed rod and a right movable rod positioned between the two crossbeams. A first motor is positioned at the top of each of the fixed and movable rods. The first motor is coupled to a first gear through the outer wall of a first rotating shaft, the first gear meshing with a vertical gear rod. A latching mechanism is positioned at the bottom of the vertical gear rod. A second motor is positioned at the top of the intermediate beam, coupled to a second gear through the outer wall of a second rotating shaft. A horizontal rack is meshed at the bottom of the second gear, the right end of which is affixed to the movable rod. The present utility model is capable of mechanically operating PC concrete slabs of varying widths within an adjustable range, enabling the clamping and displacement of PC concrete slabs with high efficiency and safety.

[0004] However, during use, when it is necessary to palletize the products produced by the PC production line, some PC products need to be stacked to complete the palletizing. The device is difficult to extract after clamping and stacking. During the extraction process, the device often has difficulty in releasing the product smoothly, causing the PC product to be easily damaged, which not only increases the scrap rate of the product, but also affects the overall efficiency of the production line. Secondly, the palletized PC products often cannot achieve the expected neatness after stacking, which can easily lead to tilting or offset during the stacking process. This unstable stacking state may also cause the PC products to collapse in the subsequent process, which is not conducive to the palletizing use of the PC production line. Utility Model Content
