[0002] The fully automatic mahjong machine in the prior art usually has a shuffling structure, a card loading structure, a card stacking structure, a card pushing structure and a card raising structure. Its working principle is that the mahjong cards are shuffled in the shuffling chassis by the shuffling structure, the card loading structure transports the mahjong cards in the shuffling chassis to the card stacking structure, the card stacking structure arranges the mahjong cards transported by the card loading structure in a regular pattern (usually two or three mahjong cards are stacked together) and transports them to the card loading track, and the card pushing structure pushes the mahjong cards arranged on the card loading track from the card raising plate to the tabletop of the mahjong table. Since the card raising plate is usually hinged to the tabletop at one end, during the card pushing process, its other end swings around the hinge shaft to connect with the card output end of the card loading track, and the connection is lower than the tabletop. The function of the card raising structure is to drive the card raising plate to swing around the hinge shaft, so that the card loading plate swings to connect with the card loading track when loading cards, and the card loading plate swings to be flush with the tabletop after loading cards are completed.

[0035] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, an integral connection, or a detachable connection; it can be the internal connection of two components; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] A mahjong machine of this embodiment is equipped with a vertical stacking structure. Figure 1-4 As shown, the card stacking structure of this embodiment is provided with a card receiving seat 200, a card pushing portion 210 and a vertical cam 240.

[0039] The axis of the vertical cam 240 of this embodiment is arranged vertically, and the upper end surface of the vertical cam 240 is provided with an annular outer edge 241, and the outer edge 241 is provided with a notch 242. Correspondingly, the bottom of the card holder 200 is provided with a first roller 202 extending to contact and cooperate with the outer edge 241.

[0040] In this embodiment, a vertical guide mechanism is provided at the bottom of the card holder. Figure 3 As shown, a vertical guide column 201 is provided at the bottom of the card holder, and a vertical guide hole adapted to the vertical guide column 201 is provided on the corresponding frame. The two cooperate to form a vertical guide mechanism, so that the card holder can only move vertically.

[0041] In this embodiment, during the rotation of the vertical cam, Figure 5 In the state shown, when the first roller is in contact with the outer edge 241, the card holder is in a high position; Figure 6 In the state shown, when the first roller enters the bottom of the recess, the card holder is in a low position.

[0042] In this embodiment, in order to enable the card holder to move smoothly from a high position to a low position, a spring 230 is provided at the bottom of the card holder. When the card holder is in a high position, the spring is in a stretched state. When the first roller enters the recess, the card holder moves down to a low position under the restoring force of the spring.

[0043] Of course, the implementation method of using a spring to ensure that the card holder can stably move from a high position to a low position is the preferred method of this embodiment. It should be understood that those skilled in the art can also adopt other structural forms, for example, the flange and the recess form a track groove adapted to the first roller, and the process of the first roller moving along the track groove can also ensure the downward movement of the card holder.

[0044] In this embodiment, Figure 2-4 As shown, the card stacking structure is further provided with a card pushing portion 210, and the card pushing portion 210 is provided with a card pushing driving mechanism, and the card pushing driving mechanism is configured to drive the card pushing portion to pass above the card receiving seat.

[0045] In this embodiment, the card pushing driving mechanism includes a slider 250, which is arranged below the vertical cam, and the slider 250 is provided with a transverse guide mechanism with the same moving direction as the card pushing part. Figure 4 As shown, the transverse guide mechanism includes a transversely arranged guide rail 251 and a guide groove 252 arranged at the bottom of the slider and adapted to the guide rail 251.

[0046] In this embodiment, the sliding block is connected to the card pushing portion 210 via a connecting bracket 211 .

[0047] In this embodiment, a cam groove is provided on the side of the slider facing the vertical cam. Fig. 9 As shown, the cam groove includes a straight line segment 253 and an arc segment 254 connected to the straight line segment. Preferably, in this embodiment, the arc segment is also connected to a second straight line segment 255.

[0048] Correspondingly, such as Figure 8 As shown, in this embodiment, a second roller 245 is provided on the side of the vertical cam facing the slider, and the second roller 245 is adapted to be connected with the cam groove. In addition, the second roller is arranged away from the axis of the vertical cam, and the rotation radius of the second roller is adapted to the arc segment of the cam groove.

[0049] Figure 7 The state shown is that the card pushing unit pushes the mahjong tiles to the card loading track. The lifting and lowering of the card receiving seat and the card pushing action are realized through the rotation of the vertical cam. The structure has a higher degree of integration, a more optimized structure, and a more reasonable layout.

[0050] In this embodiment, a gear transmission mechanism is provided between the driving motor 100 for driving the vertical cam to rotate and the vertical cam, and the driving force is transmitted through the gear transmission mechanism.

[0051] In this embodiment, the gear transmission mechanism includes a first gear 110 connected to the output shaft of the driving motor 100, a second gear 120 meshing with the first gear 110, a third gear 244 coaxially connected to the second gear 120, and a fourth gear 243 meshing with the third gear 244. The fourth gear 243 is coaxially connected to the vertical cam. Preferably, in this embodiment, the fourth gear and the vertical cam are an integrated structure.

[0052] As a preference, Figure 1 As shown, in this embodiment, a box structure 220 is provided to arrange the vertical card stacking structure in the box structure 220, so that the installation is more convenient and the structure is more compact.

[0053] In short, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
