The deck plate 72 may be configured as disclosed in patent documents CN109381855, and the deck plate 72 may be fixed to the upper portion of the upper deck 70 or may be integrally formed with the upper deck 70. The structure disclosed in patent documents such as CN112023390A and the like can be adopted, and the card supporting plate 72 can be used to lift up and down, so as to reduce the lifting span of the card supporting block 61 in the card pushing device 6 and improve the card stacking and pushing efficiency and stability. Thus, the tile feeding transmission mechanism further comprises a lifting driving mechanism of the tile bearing plate 72, as shown in fig. 47 to 48, the lifting driving mechanism of the tile bearing plate 72 comprises a tile lifting crank and a tile lifting support frame, the bottom of the tile bearing plate 72 is connected with the tile feeding seat 70 in a vertical sliding manner through a tile lifting guide shaft and a tile lifting guide shaft seat, two tile lifting support frames are arranged on two sides of the bottom of the tile bearing plate 72, a tile lifting cam curve is arranged at the bottom of each tile lifting support frame, and the flat pushing tile feeding motor 76 pushes the tile lifting support frames through the tile lifting crank so as to drive the tile bearing plate 72 to lift. In this embodiment, the card support plate 72 has at least two stop positions: when the first stop position is low, the mahjong support plate 72 supports two mahjong pieces which are stacked into a pier and are pushed by the mahjong pushing device 6; when the second stop position is high, the mahjong pushing plate 73 pushes the piles of mahjong arranged on the mahjong supporting plate 72 to the mahjong supporting plate 71. Therefore, the mahjong supporting plate 72 descends to a low position to support the mahjong pieces pushed by the mahjong pushing device 6, when the mahjong pieces are pushed horizontally, the mahjong supporting plate 72 ascends to a high position to push the mahjong pieces to the mahjong supporting plate 71, the lifting span (the thickness of one mahjong piece) of the mahjong supporting block 61 in the mahjong pushing device 6 is greatly reduced, and the mahjong stacking efficiency and stability are improved. Preferably, the inner side of the mahjong support plate 72 is provided with an inner side blocking wall, the outer side of the mahjong support plate 72 is provided with an outer side blocking wall, the inner side blocking wall and the outer side blocking wall are integrally formed or fixedly connected with the mahjong upper seat 70, and when the mahjong support plate 72 rises upwards, the height of the mahjong support plate is higher than that of the inner side blocking wall, so that mahjong tiles on the mahjong support plate 72 can be prevented from falling out in a mess. In this embodiment, the card-feeding transmission mechanism adopts a horizontal pushing card-feeding motor 76 to drive the card-supporting plate 71, the card-supporting plate 72 and the card-pushing plate 73, so as to realize card-lifting, card-pushing and card-feeding.

In other embodiments, the flat push-up device 7 with the liftable support plate 72 can also be combined with a push device 6 for pushing a single mahjong tile, so that the support plate 72 has at least three stop positions: when the mahjong tiles are in the first stop position, the tile bearing plate 72 bears the single mahjong tiles pushed by the tile pushing device 6 and arranges the single mahjong tiles to form a first layer of mahjong tiles; when the mahjong tiles are in the second stop position, the tile bearing plate 72 bears the single mahjong tiles pushed by the tile pushing device 6 and arranges the single mahjong tiles to form a second layer of mahjong tiles; in the third position, the pushing plate 73 pushes the piles of mahjong arranged on the supporting plate 72 to the supporting plate 71.

In other embodiments, the horizontal pushing and card-putting device 7 having the lifting and lowering card-supporting plate 72 may also be used for putting cards in stages, for example, three layers of mahjong cards are stored on the card-supporting plate 72, when putting cards, the card-supporting plate 71 descends to the bottom, the card-pushing plate 73 pushes the top layer of mahjong cards onto the card-supporting plate 71, the card-supporting plate 71 ascends to lift the mahjong cards to the table top, after the player takes the mahjong cards away, the card-supporting plate 71 descends again, the card-pushing plate 73 pushes the remaining two layers of mahjong cards onto the card-supporting plate 71, and the card-supporting plate 71 ascends to push the mahjong cards to the table top.

In the prior art, in the horizontal push type windmill-shaped mahjong machine disclosed in patent documents CN209645828U, CN109381855A, CN112023390A and the like, the square tile wall inclined in the windmill shape is located further outside than the square tile wall of the slope type windmill-shaped mahjong machine, and generally, a player needs to push the mahjong tile wall into a little to be suitable for playing cards by the player, which still causes inconvenience to the player. It is therefore preferable that the wall of tiles be pushed inward, as much as the wall of tiles in a ramp-up windmill-shaped mahjong machine, so that the player does not need to push the tiles any more.

In one embodiment, the tile supporting plate 71 and the driving mechanism thereof adopt the prior art structure, the tile supporting plate 71 extends and widens inwards, the width of the tile supporting plate 71 is larger than that of the mahjong tile wall, namely, a supporting area for placing the mahjong tile wall and a transition area which is positioned outside the supporting area and is not used for placing the mahjong tile wall are formed on the tile supporting plate 71, and the transition area is only connected with the tile supporting plate 72 when the tile pushing plate 73 pushes tiles and is used for pushing the mahjong tile wall to pass through. However, such a structure has several problems: firstly, the mahjong machine is influenced by arranging the wide mahjong-feeding ports and the mahjong-supporting plates on the table top plate, secondly, the four wide mahjong-feeding ports can cause the hollow area of the table top plate to be large, the strength is low, the mahjong-playing machine is easy to deform, then, in order to avoid that the lifting assembly (comprising the guide rod, the mahjong-feeding crank, the mahjong-feeding cam and the like) at the bottom of the mahjong-supporting plate 71 excessively occupies a shuffling space, the supporting position of the lifting assembly on the mahjong-supporting plate 71 is generally outside the mahjong wall, so that the mahjong-supporting plate is unbalanced in supporting and not stable enough, the mahjong-supporting plate is easy to loosen, and the service life of the mahjong machine is influenced. Of course, the latter two problems can be solved by improving materials, adding reinforcements or reinforcing structures, and therefore, the embodiment can be used in occasions with low requirements on the appearance of the mahjong machine.

In another embodiment, the width of the card supporting plate 71 is unchanged, the position of the card supporting plate 71 is moved inwards, when the card supporting plate 71 is lowered to the bottom, a transition plate 74 is arranged between the card supporting plate 71 and the card supporting plate 72, so that the card supporting plate 72 and the card supporting plate 71 are connected and a mahjong wall can be pushed to pass through when the card pushing plate 73 pushes cards. Wherein, the transition plate 74 is arranged on the card supporting plate 71, the card supporting plate 72 or the card feeding seat 70. The transition plate 74 may be fixed to or integrally formed with the card support plate 72 or the card shoe 70.

Preferably, in this embodiment, as shown in figures 24, 25, 34, 37, 40, 43, 47 and 48, the transition plate 74 is hinged to the inside of the card support plate 72 or the card shoe 70 so that the transition plate 74 can be erected or laid flat. Thus, when the card is stored by pushing the card-loading device 7 horizontally, as shown in fig. 25, the transition plate 74 is in a standing state so as to serve as an inner side blocking wall of the card-supporting plate 72 to prevent the mahjong from falling off the card-supporting plate 72; when the tile pushing device 7 pushes tiles horizontally, as shown in fig. 26 and 27, the tile supporting plate 71 descends, the transition plate 74 is laid horizontally, and the tile pushing plate 73 pushes the mahjong tile wall inwards; as shown in fig. 28 and 29, the transition plate 74 is laid flat to form a transition area through which the mahjong wall can be pushed; as shown in fig. 30 and 31, the mahjong tile pushing plate 73 pushes the mahjong tile wall to the tile supporting plate 71 to be reset, and the transition plate 74 is erected to be reset; as shown in fig. 32 and 33, the support plate 71 raises the wall of the tiles up the mahjong table. Simple structure, simple to operate, the function is reliable.

It is further preferred that the transition plate 74 impart a tendency for the transition plate 74 to rise upwardly through the elastic member. Therefore, the transition plate is in a standing state under the state of no external force, and the mahjong tile pushing plate is pressed and laid flat, so that the interference between the transition plate 74 and the mahjong tile supporting plate 71 can be avoided, and an additional supporting piece is not required to be arranged for supporting the transition plate. The elastic member may be a tension spring, a torsion spring, or an elastic push rod, but is preferably a torsion spring sleeved on the hinge shaft of the transition plate 74.

Preferably, in this embodiment, the transition plate 74 is provided with a spring to give the transition plate 74 a tendency to lay flat. The transition plate is in a flat state without external force, so that the load of the motor for pushing the mahjong tiles is reduced, the collision noise of the mahjong tiles is reduced, and the transition plate is supported by an additional supporting structure or a supporting piece. The elastic member may be a tension spring, a torsion spring, or an elastic push rod, but is preferably a torsion spring sleeved on the hinge shaft of the transition plate 74.

Thus, the first transition support 711 can not only support the transition plate 74, but also form a support with the bottom of the table top plate 4, thereby improving the stability of the card support plate, avoiding the influence of looseness on the service life, and having simple and reliable structure and low cost. The first transition supporting member 711 may be a whole plate, or may be formed by a plurality of small supporting plates, or may be an independent component fixedly connected to the card supporting plate 71, or may be integrally formed with the card supporting plate 71. In the present embodiment, the first transition supporting member 711 is preferably a unitary plate integrally formed with the card supporting plate 71, so that the support is more secure and reliable. More preferably, the lifting guide member (guide rod or guide sleeve) of the tile supporting plate 71 is arranged on the first transition support member 711, and the tile feeding cam 713 of the tile supporting plate 71 is arranged at the bottom of the tile supporting plate 71, so that the tile supporting plate 71 and a mahjong tile wall thereon can be supported more uniformly and stably, further the tile supporting plate 71 is prevented from loosening, and the service life is prolonged.

Further preferably, a second transition support part 712 is arranged at the outer side of the first transition support part 711, and the second transition support part 712 is vertically arranged and fixedly connected with the first transition support part 711 or integrally formed; the second transition support 712 forms an inboard stop for the transition plate 74 when the transition plate 74 is raised up with the card support plate 71. Therefore, not only can the transition plate 74 be reliably limited and blocked, but also the transition plate 74 can be prevented from being turned inwards to interfere the lifting of the card supporting plate 71. The first transition support 711 may be a full plate, but is preferably constructed of at least two small support plates.

In other embodiments, the transition plate 74 may be movably disposed at the bottom of the card support plate 71.
