Description

Electric mahjong table opening and closing device

The invention relates to the technical field of electric mahjong tables, and in particular, to a special tile collecting and opening and closing device for the electric mahjong table.

Press, the electric mahjong table is equipped with four tile raising areas at intervals on the tabletop, and a control panel and a tile collecting port are provided in the center of the tabletop, and a lifting device and a tile sorting device are provided inside the table body. When the lifting device drives the control panel to rise , when opening the card collection port, let the player push the mahjong tiles on the table to fall into the card collection port, and then the lifting device drives the control panel to lower and close the card collection port, and then cooperates with the card sorting device to shuffle, stack, push and push the cards. Raising tiles allows the mahjong tiles to be arranged on the rising tiles area, and while a mahjong game is in progress, the mahjong tiles to be used in the next game have been arranged and ready to be played, and there is no need to wait for the tile sorting process.

In the current mahjong game, when the lifting device drives the control panel upward to allow the player to push the mahjong tiles on the table to fall into the tile collection port, most of the mahjong tiles directly hit the lifting device and the tile sorting device downwards, resulting in loud noise and mahjong.
