[0027] The implementation principle of a pallet rotation mechanism for an accumulation roller conveyor line according to an embodiment of this application is as follows: During operation, firstly, the height of the lifting plate 31 is raised or lowered using the lifting cylinder 41 according to the height of the pallet, so that the height of the clamping rod 61 is suitable for pallets of different heights. When the pallet on the first roller conveyor line 1 moves between the two clamping rods 61, the clamping cylinder 71 drives the two clamping rods 61 to move relative to each other to clamp the pallet. Then, the rotating motor 51 drives the drive rod 52 to rotate. The drive rod 52 drives the first slider 54 to reciprocate in the first slide groove through the fixed column 53. When the first slider 54 moves to the middle position of the first slide groove twice during the reciprocating motion, the rotating rod 311 is respectively placed on the first roller conveyor line 1 and the second roller conveyor line 2. In this way, the pallet can be rotated onto the second roller conveyor line 2. Then, the clamping rod 61 can be released. This setting can be applied to pallets of different widths.
