[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0047] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0048] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. 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.

[0049] This embodiment presents an integrated module that combines card raising, card stacking, and card conveying into one unit, such as... Figures 1-2 , Figures 5-7 As shown, it includes a housing 60, a stacking drive mechanism, a card lifting mechanism 20, a card pushing mechanism 30, and a card conveying mechanism 50. The housing 60 has an internal mounting cavity 62.

[0050] In this embodiment, as Figures 5-7 As shown, the stacking drive mechanism includes a stacking motor 10, a main drive gear 11, a card-lifting drive gear 21 for driving the card-lifting mechanism 20, and a card-pushing drive gear 31 for driving the card-pushing mechanism 30. The main drive gear 11 is mounted on the output shaft of the stacking motor 10. The card-pushing drive gear 31 and the card-lifting drive gear 21 are located on opposite sides of the main drive gear 11 and mesh with it.

[0051] 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.

[0052] The unique feature of this embodiment lies in the structural design and layout where the card-pushing drive gear 31 and the card-lifting drive gear 21 are located on both sides of the main drive gear 11. This arrangement places the card-lifting mechanism 20 and the card-pushing mechanism 30 on both sides of the card-lifting motor 10, extending the installation space to both sides of the card-lifting motor 10. Compared to existing technologies, this reduces the axial installation dimensions of the card-lifting motor 10. This structural form optimizes the internal space layout of the mahjong machine, resulting in higher space utilization. Furthermore, this layout provides a better structural foundation for integrating the card-lifting and card-pushing mechanisms into a single unit.

[0053] 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.

[0054] 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 6 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.

[0055] In this embodiment, as Figure 1 As shown, the first transmission gear 22, the second transmission gear 23, the rocker arm gear 24, the lifting rocker arm 26, and the rocker arm connecting rod 25 are disposed on one side of the outer side of the housing, as shown. Figure 3 , Figure 4 As shown, this side is the side closest to the center of the mahjong machine.

[0056] In this embodiment, as Figure 8 As shown, the rocker arm gear 24 is provided with a first eccentric column 241.

[0057] In this embodiment, as Figure 7 , Figure 10As 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.

[0058] In this embodiment, as Figure 9 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.

[0059] The card-stacking mechanism in this embodiment, such as Figures 5-7 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 11-12 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.

[0060] like Figure 1 As shown, in this embodiment, the card holder 36 and the card pusher 38 are located on one side of the outer casing near the end of the casing, and the card holder and the card pusher are located on the same side of the outer casing as the rocker arm gear.

[0061] In this embodiment, as Figures 11-12 As shown, the cam 33 is disposed in the mounting cavity, 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.

[0062] In this embodiment, as Figure 14 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.

[0063] In this embodiment, as Figure 15As 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.

[0064] In this embodiment, the transmission route of the transmission mechanism is as follows: 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.

[0065] In this embodiment, as Figures 5-7 As shown, the slide rail 34 is horizontally fixed in the mounting cavity of the housing, and the slider 35 is slidably connected to the slide rail 34, as shown. Figure 13 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.

[0066] In this embodiment, as Figure 7 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.

[0067] 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.

[0068] like Figure 5 , Figure 6 As shown, the card-carrying mechanism 50 of this embodiment includes a card-suction wheel 52, a conveying mechanism 53, and a drive assembly for driving the card-suction wheel. Figure 2As shown, in this embodiment, the card suction wheel and the conveying mechanism are disposed in the mounting cavity. The end of the mounting cavity away from the card holder is provided with a card conveying outlet 61. The driving component is disposed on the outside of the housing away from the rocker arm gear.

[0069] In this embodiment, the driving component includes a drive motor 40, a drive gear 41 mounted on the output shaft of the drive motor, and a driven gear 51 meshing with the drive gear. The driven gear 51 is coaxially and fixedly connected to the card-collecting wheel 52. The drive motor 40 drives the card-collecting wheel 52 to rotate, thereby conveying the mahjong tiles to the conveying mechanism 53 and sending them out of the conveying mechanism 50 through the card-collecting outlet 61.

[0070] In this embodiment, preferably, the conveying mechanism includes multiple rollers 531 arranged side by side. Each roller 531 has a transmission gear 532 at its end. The suction wheel 52, on its side away from the driven gear, also has a transmission gear 54 coaxially and fixedly connected to it. The mechanism also includes transition gears 533 located between the transmission gear 532 and the transmission gear 532, and between adjacent transmission gears 532. Thus, during the rotation of the suction wheel, the interaction between the transmission gear 54, the transition gear 533, and the transmission gear 532 provides conveying power for the mahjong tiles, ensuring efficient delivery of the tiles.

[0071] like Figure 3 , Figure 4 As shown, a mahjong machine using an integrated module that combines card raising, card stacking, and card conveying according to this embodiment includes a frame 200 and four sets of integrated modules 100 that combine card raising, card stacking, and card conveying. Each of the four sets of integrated modules 100 is installed as a whole module in one of the four positions on the frame 200. The card raising plate 300 is located on the side of the machine casing near the center and is driven to rise and fall by the card raising mechanism.

[0072] The special feature of this embodiment is that, through the modular design of multiple mechanisms, the lifting, stacking, and conveying of the cards are integrated into one module, making the function of the module more concentrated. The modular design improves assembly efficiency and the ease of disassembly and assembly during maintenance.

[0073] 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.
