A device for pushing and receiving cards of a mahjong machine

Abstract

The invention relates to a pushing and receiving device of a mahjong machine. The pushing and receiving device comprises a driving roller, a pushing head, a receiving board a small rocker, a carrying board, a storing board, a pushing board, two driving rods and two driving cams. The storing board is arranged on a frame, the carrying board is disposed on one side of the storing board in the width direction and can slide upwards and downwards, the pushing board is connected with the upper end face of the storing board and can slide along the width direction of the storing board, the two driving cams are rotatingly connected with the frame under two ends in the length direction of the storing board, each driving cam is pressed on a cam surface of each driving cam by an input end of each driving rod, and output ends are connected with and used for driving the pushing board. The pushing head is disposed at one side of the storing board in the length direction, the driving rod is rotatingly supported on the frame, one end of the small rocker is hinged to the frame, the other end is movably connected with the pushing head, and the rocker is provided with a guide pin. The pushing and receiving device of the mahjong machine is simple in the whole structure, less in driving components, convenient to produce and assemble, so the profit of a manufacturer can be raised.

Description

technical field [0001] The invention relates to a mahjong machine, in particular to a device for pushing and receiving tiles of the mahjong machine. Background technique [0002] The mahjong that has been washed in the shuffling barrel is sent to the card accumulation seat through the conveyor belt. After the two mahjong are superimposed on the card accumulation seat to form an upset, they are pushed to the card pushing board and transported to the card storage slot through the card pushing board. The bearing board, the bearing board transports the washed mahjong to the desktop of the automatic mahjong machine. The vast majority of existing card pushing boards are provided with a drive mechanism at the center of the card pushing board. Due to the long length of the card pushing board, during the process of pushing cards by the pushing board, the stacked mahjong tiles will be damaged.

AI Technical Summary

Problems solved by technology

The vast majority of existing card pushing boards are provided with a drive mechanism at the center of the card pushing board. Due to the long length of the card pushing board, during the process of pushing cards by the pushing board, the stacked mahjong tiles will be damaged. Misalignment, and the existing plate drive mechanism has a complex structure, many transmission parts, and mechanical failures are prone to occur. Once a failure occurs, it is difficult to diagnose and the maintenance cost is high.
