For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0045] This embodiment describes a stacking mechanism for mahjong tiles, applied in a mahjong machine. Wherein, as... Figures 1-3 As shown, the card stacking mechanism includes a stacking motor 10, a main drive gear 11, a card lifting mechanism 20, and a card pushing mechanism 30. The main drive gear 11 is mounted on the output shaft of the stacking motor 10.

[0046] As a special feature of this embodiment, it also includes a card-lifting drive gear 21 for driving the card-lifting mechanism 20 and a card-stacking drive gear 31 for driving the card-stacking mechanism 30. The card-stacking drive gear 31 and the card-lifting drive gear 21 are located on both sides of the main drive gear 11 and mesh with the main drive gear 11 respectively.

[0047] In this embodiment, the card-lifting drive gear 21 is mounted on the card-lifting drive shaft 211 via a first one-way mechanism 212, and the card-stacking drive gear 31 is mounted on the card-stacking drive shaft 311 via a second one-way mechanism 312. Furthermore, the transmission directions of the first one-way mechanism 212 and the second one-way mechanism 312 are opposite. Thus, the forward and reverse rotation of the stacking motor 10 drives the card-lifting mechanism 20 and the card-stacking mechanism 30 to operate, respectively.

[0048] The special feature of this embodiment is that, through the structural design and layout of the stacking and pushing drive gear 31 and the lifting drive gear 21 located on both sides of the main drive gear 11, the lifting mechanism 20 and the stacking and pushing mechanism 30 are arranged on both sides of the stacking motor 10, and the installation space is extended to both sides of the stacking motor 10. Compared with the prior art, the axial installation size of the stacking motor 10 is reduced. This structural form optimizes the internal space layout of the mahjong machine, making the internal space utilization rate of the mahjong machine higher.

[0049] It should be noted that the first one-way mechanism 212 and the second one-way mechanism 312 in this embodiment can be any one of the one-way bearings, one-way clutches or one-way ratchet mechanisms in the prior art. There is no restriction in this embodiment, but one-way bearings are preferred.

[0050] In this embodiment, the card-lifting mechanism includes a first transmission gear 22, a second transmission gear 23, a rocker arm gear 24, a card-lifting rocker arm 26, and a rocker arm connecting rod 25. Wherein, as... Figure 2 As shown, the first transmission gear 22 is coaxially arranged with the lifting drive gear 21, and the first transmission gear 22 is fixedly connected to the lifting drive shaft 211. The second transmission gear 23 is located between the first transmission gear 22 and the rocker arm gear 24, and the second transmission gear 23 meshes with the first transmission gear 22 and the rocker arm gear 24 respectively. The power output by the stacking motor 10 is transmitted to the rocker arm gear 24 in sequence through the main drive gear 11, the first transmission gear 22 and the second transmission gear 23.

[0051] In this embodiment, as Figure 4 As shown, the rocker arm gear 24 is provided with a first eccentric column 241.

[0052] In this embodiment, as Figure 3 , Figure 6As shown, the lower end of the lifting rocker arm 26 is provided with a first hinge shaft 261 for hinged engagement with a fixedly mounted hinge seat 27. The upper end of the lifting rocker arm 26 is provided with a lifting drive roller 262 for engaging with the lifting plate to drive the lifting plate to rise and fall. The lifting rocker arm 26 is provided with a second hinge shaft 263 for hinged engagement with the rocker arm connecting rod 25, and the second hinge shaft 263 is located between the first hinge shaft 261 and the lifting drive roller 262.

[0053] In this embodiment, as Figure 5 As shown, one end of the rocker arm connecting rod 25 is hinged to the first eccentric column 241 through the first hinge hole 251, and the other end of the rocker arm connecting rod 25 is hinged to the second hinge shaft 263 on the lifting rocker arm 26 through the second hinge hole 252. Thus, the rotational motion of the rocker arm gear 24 can be converted by the rocker arm connecting rod 25 into the oscillation of the lifting rocker arm 26 around the first hinge shaft 261, thereby driving the lifting plate to rise and fall.

[0054] The card-stacking mechanism in this embodiment, such as Figures 1-3 As shown, the assembly includes a third transmission gear 32, a cam 33, a card holder 36, a card holder rocker arm 37, a slide rail 34, a slider 35, and a card pusher head 38. The third transmission gear 32 is coaxial with the card-pushing drive gear 31, and is fixedly mounted on the card-pushing drive shaft 311. Figures 7-8 As shown, the cam 33 is provided with an external gear 333 that meshes with the third transmission gear 32, and the third transmission gear 32 and the stacking pusher drive gear 31 are respectively located on both sides of the slider 35.

[0055] In this embodiment, as Figures 7-8 As shown, a cam track groove 331 is provided on one side end face of the cam 33, and a second eccentric column 332 is provided on the other side end face of the cam 33.

[0056] In this embodiment, as Figure 10 As shown, the plate holder 36 is provided with a vertical guide portion 361, and a horizontally extending waist-shaped transmission groove 362 is provided on one side of the plate holder 36.

[0057] In this embodiment, as Figure 11 As shown, one end of the tile-bearing rocker arm 37 is provided with a first stacking tile transmission roller 371 adapted to the cam track groove 331, and the other end of the tile-bearing rocker arm 37 is provided with a second stacking tile transmission roller 372 adapted to the waist-shaped transmission groove 362. Furthermore, the tile-bearing rocker arm 37 is also provided with a hinge portion 373 located between the first stacking tile transmission roller and the second stacking tile transmission roller. The tile-bearing rocker arm 37 is hinged to the frame inside the mahjong machine through the hinge portion 373.

[0058] In this embodiment, the power of the stacking motor 10 is transmitted to the cam 33 in sequence via the main drive gear 11 and the third transmission gear 32. Based on the cooperation between the cam track groove 331 and the first stacking card transmission roller 371, the card holder rocker arm 37 is driven to swing around the hinge part 373. Then, through the cooperation between the second stacking card transmission roller 372 and the waist-shaped transmission groove 362, the card holder 36 is driven to rise and fall.

[0059] In this embodiment, as Figures 1-3 As shown, the slide rail 34 is fixedly arranged laterally, and the slider 35 is slidably connected to the slide rail 34, as follows. Figure 9 As shown, the slider 35 has a slider track groove 351 on the side facing the cam 33 for accommodating the second eccentric column 332. Based on the cooperation between the second eccentric column 332 and the slider track groove 351, the rotational motion of the cam 33 is converted into the reciprocating movement of the slider 35 on the slide rail 34.

[0060] In this embodiment, as Figure 3 As shown, it also includes a connecting arm 39 fixedly connected to the slider 35. The free end of the connecting arm 39 is provided with a reference shaft 391. The pusher head 38 is provided with a pusher link 381, and the free end of the pusher link 381 is connected to the reference shaft 391.

[0061] In this embodiment, the connection between the pusher rod 381 and the reference shaft 391 can include two methods: one is that the reference shaft is a fixed shaft, and the pusher rod is rotatably connected to the reference shaft; the other is that the reference shaft is a rotating shaft, and the pusher rod is fixedly connected to the reference shaft. Regardless of the connection method, the pusher head 38 can swing around the reference shaft 391. Accordingly, to allow the pusher head 38 to return to its original position after swinging around the reference shaft 391, a return elastic element 310 should be provided. The return elastic element 310 can be a compression spring or a torsion spring located at the reference shaft.

[0062] In summary, the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
