Description

Technical Field

[0001] The utility model belongs to the technical field of mahjong machine equipment, and particularly relates to a novel mahjong machine card loading device. Background Art

[0002] An automatic mahjong machine typically consists of a tile-lifting device, a tile-pushing device, a tile-feeding device, and a tile-sucking device. The tile-sucking device feeds the tiles onto the tile-feeding device, which stacks the tiles and feeds them into the tile-pushing device. The tile-pushing device then pushes the tiles to the tile-lifting device, where they are then transported to the tabletop. However, the existing tile-pushing device uses a tile-pushing rod to push the tiles toward the tile-lifting device. Because each tile pile rubs against its track on three sides during pushing, considerable frictional resistance inevitably occurs. This causes the tile-pushing rod to shake during pushing, leading to the tiles becoming stuck. Furthermore, the tile-lifting device is connected to the motor via multiple connecting rods, resulting in a long transmission distance and poor stability. Summary of the Invention
