Mahjong machine card issuing mechanism

Abstract

This invention provides a mahjong tile-feeding mechanism, including a mounting base inside a tile-feeding housing, a circular tile-feeding track on the outer side of the mounting base, a tile-pushing mechanism on the mounting base, and a tile-lifting groove on one side of the tile-feeding housing that communicates with the tile-feeding track. The tile-lifting groove extends outward along the circumferential tangent of the tile-feeding track, and a tile-lifting mechanism is movably mounted within the tile-lifting groove. A drive mechanism is located at the lower end of the tile-feeding housing, and the drive mechanism is connected to a gear transmission mechanism mounted on the tile-feeding housing. The gear transmission mechanism drives the tile-pushing mechanism and the tile-lifting mechanism to move and achieve tile feeding. In practical use, the tile-pushing and tile-lifting mechanisms can achieve automatic tile feeding, solving the problems of excessive motors in existing tile-feeding mechanisms, which lead to cumbersome assembly, complex structure, low production efficiency, high cost, and negatively impact the normal operation of the mahjong machine.

Claims

1. A mahjong machine card-feeding mechanism, comprising a mounting base inside a card-feeding housing, a card-feeding track on the outer side of the mounting base, the card-feeding track being annular, a card-pushing mechanism on the mounting base, a card-lifting groove on one side of the card-feeding housing communicating with the card-feeding track, the card-lifting groove extending outward along the circumferential tangent of the card-feeding track, a card-lifting mechanism movably disposed within the card-lifting groove, a driving mechanism at the lower end of the card-feeding housing, the driving mechanism being connected to a gear transmission mechanism disposed on the card-feeding housing, the gear transmission mechanism driving the card-pushing mechanism and the card-lifting mechanism to move and achieve card-feeding.

2. The mahjong machine card-issuing mechanism as described in claim 1, wherein, The card-pushing mechanism includes a card-pushing rod and a card-pushing head mounted on the card-pushing rod. The rotation of the card-pushing rod drives the card-pushing head to move along the card-feeding track.

3. The mahjong machine card-issuing mechanism as described in claim 1, wherein, The card-lifting mechanism includes a card-lifting plate hinged to a card-lifting slot and a card-lifting frame for connecting a gear transmission mechanism and the card-lifting plate.

4. The mahjong machine card-issuing mechanism as described in claim 1, wherein, The upper end of the license plate housing has a track boss located on the inner side of the license plate track, and the mounting seat is located at the center of the track boss.

5. The mahjong machine card-issuing mechanism as described in claim 4, wherein, The card-loading track has a card-in end and a card-out end, with one end of the card-lifting slot connected to the card-out end.

6. The mahjong machine card-issuing mechanism as described in claim 1, wherein, The gear transmission mechanism includes a pusher gear transmission assembly connected to the pusher rod and capable of driving the pusher rod to rotate intermittently along the circumference of the card-raising track, and a lifting gear transmission assembly linked to the lifting plate and capable of driving the lifting plate to move up and down when the pusher rod stops.

7. The mahjong machine card-issuing mechanism as described in claim 6, wherein, The card-pushing gear transmission assembly includes a card-pushing driving wheel and a card-pushing driven wheel. The card-pushing driving wheel meshes with the card-pushing driven wheel. The rotation of the card-pushing driving wheel drives the card-pushing driven wheel to rotate. The card-pushing driven wheel is provided with push posts arranged in a circumferential interval. The mounting base is provided with grooves that match the push posts. The card-pushing driven wheel is embedded in the mounting base, thereby driving the card-pushing rod to rotate intermittently along the card-feeding track.

8. The mahjong machine card-issuing mechanism as described in claim 7, wherein, The card-lifting gear transmission assembly includes a card-lifting drive wheel and a card-lifting driven wheel. The card-lifting drive wheel meshes with the card-lifting driven wheel. The rotation of the card-lifting drive wheel drives the rotation of the card-lifting driven wheel. The card-lifting driven wheel is connected to the card-lifting plate and is fixedly connected to the card-lifting plate, so that when the card-pushing rod stops, it can drive the card-lifting plate to move up and down.

9. The mahjong machine card-issuing mechanism as described in claim 1, wherein, The drive mechanism includes a drive motor and a transmission shaft located at the lower end of the card holder housing. The transmission shaft is connected to the output shaft of the drive motor. Both the push-card drive wheel and the lift-card drive wheel are located on the transmission shaft.
