For example, the mahjong machine disclosed in the patent application for invention with the publication number CN107583269A. Since all the mahjong tiles are driven, the collision between the mahjong tiles is more, and the noise during shuffling is relatively large, which is not good for the user experience. In addition, in order to transfer the shuffled mahjong tiles to the tile stacking mechanism, the tile suction motor is generally used to drive the tile suction wheel to achieve the purpose. Since the shuffling motor and the tile suction motor need to be arranged respectively to drive the shuffling cylinder and the tile suction disc, not only the number of motors is large, the production cost is high, but also the space occupied is large, and it is difficult to realize the ultra-thin design of the mahjong machine.

[0008] Further, the outer periphery of the card shuffling disc is provided with four card suction discs and four first driven gears, and the frame is provided with four driving motors, and each driving motor drives one card suction disc and one first driven gear.

[0009] Further, the first driven gear is installed on the first rotating shaft through the one-way bearing, the first rotating shaft is in transmission connection with the card suction disc and is locked by the one-way bearing to drive the first driven gear to rotate, the driving motor stops working when the card suction disc sucks the mahjong tiles, the first rotating shaft stops rotating, and the first driven gear rotates along with the first ring gear due to the free rotation of the one-way bearing.

[0024] like Figures 1 to 7 As shown, the present invention provides a low-noise mahjong machine, including a frame 1, a shuffling cylinder 2, and a tabletop 3. The tabletop 3 is located above the shuffling cylinder 2. The bottom of the shuffling cylinder 2 has a shuffling plate 21, and the outer side of the shuffling cylinder 2 is provided with a suction plate 4. The frame 1 is provided with a drive motor 5 for driving the suction plate 4 to rotate. The shuffling plate 21 is fixed relative to the frame 1. The shuffling cylinder 2 is provided with a through hole 20 for the mahjong tiles to move from the shuffling plate 21 to the suction plate 4. Above the shuffling plate 21 is a card-pushing component 6 for pushing the mahjong tiles 9 to shuffle and push the mahjong tiles to the suction plate 4. The card-pushing component 6 is connected to the drive motor 5 and rotates relative to the shuffling plate 21 under the drive of the drive motor 5 to achieve shuffling. The suction plate 4 is horizontally set and extends into the through hole 20, level with the shuffling plate 21.

[0025] The invention fixes the shuffling disc 21 on the frame 1, since the shuffling disc 21 bearing mahjong tiles is fixed, and mahjong tiles are moved by the tile pushing piece 6, only mahjong tiles subjected to the force of the tile pushing piece 6 are pushed, unlike the prior art in which all mahjong tiles on the shuffling disc 21 move, so that the collision between a small number of mahjong tiles pushed is greatly reduced, the source of noise is controlled, the noise during shuffling is naturally reduced, and the user experience is better. The driving motor 5 driving the tile suction disc 4 simultaneously drives the tile pushing piece 6 to shuffle, which not only saves the number of motors used, reduces production and use costs, but also reduces the space occupied by the motor, which is beneficial to the ultra-thin design of the mahjong machine. Since the tile suction disc 4 is horizontally arranged and extends into the through hole 20 and is flush with the shuffling disc 21, when the tile pushing piece 6 pushes the mahjong tiles to move, the mahjong tiles will move to the edge of the shuffling disc 21 and finally move to the tile suction disc 4 to be taken away from the shuffling disc 21 by the tile suction disc 4. The mahjong tiles basically maintain translation during movement and will not be turned over, so noise is not easily generated, further realizing low-noise shuffling and tile suction.

[0026] In the embodiment, in order to realize shuffling and push mahjong tiles out of the through hole 20, the tile pushing piece 6 can be designed to include a rotating shaft 61, a pushing plate 62, and an outer ring body 63. The rotating shaft 61 is rotationally connected to the center of the frame 1 or the shuffling disc 21. The pushing plate 62 is connected between the rotating shaft 61 and the outer ring body 63. The height difference H1 between the pushing plate 62 and the shuffling disc 21 is less than the thickness B of the mahjong tile, ensuring that all mahjong tiles cannot pass through the gap between the pushing plate 62 and the shuffling disc 21, and mahjong tiles will not be stuck between the pushing plate 62 and the shuffling disc 21 to affect the rotation of the tile pushing piece 6. The height difference H2 between the outer ring body 63 and the shuffling disc 21 is greater than the thickness B of the mahjong tile and less than the width W of the mahjong tile, ensuring that the mahjong tile can pass through the gap between the outer ring body 63 and the shuffling disc 21 lying down (with the characters facing up or down), so as to follow the tile suction disc 4 to pass through the through hole 20 and leave the shuffling disc 21. The outer ring body 63 is in transmission connection with the driving motor 5. Specifically, a first gear ring 631 can be arranged on the outer ring body 63, a first driven gear 11 can be arranged on the frame 1 and engaged with the first gear ring 631, and the first driven gear 11 is driven by the driving motor 5. In addition, the rotating shaft 61 can also be in transmission connection with the driving motor 5. The mahjong tile is generally a cuboid structure and has a built-in magnet. The thickness B, width W, and length L of the mahjong tile 9 can refer to Figure 8 , and in general cases, B < W < L.

[0027] Generally, in order to make the mahjong tiles face down when stacking, a tile turning magnet is arranged on the outer bottom surface of the shuffling cylinder. When the mahjong tiles are pushed by the tile pushing piece and pass through the tile turning magnet, if the tiles face up, the tiles will instantly complete the tile turning action and become face down due to the repulsive action of the magnetic force. If the mahjong tiles in the shuffling cylinder fail to complete the tile turning and remain face up, the tiles will also be instantly turned to face down by the magnetic force of the tile suction magnet when moving to the tile suction plate.

[0028] Since the driving motor 5 drives the tile suction plate 4 and the tile pushing piece 6 at the same time, it is necessary to select the power transmission mode through the tile suction plate 4 to the tile pushing piece 6 or through the tile pushing piece 6 to the tile suction plate 4. In order to pursue the ultra-thin design of the mahjong machine, the driving motor 5 is arranged on the outer side of the shuffling cylinder 2 and the former transmission mode is selected. Therefore, the second gear ring 41 can be arranged on the tile suction plate 4, the driving motor 5 is in transmission connection with the second gear ring 41 to drive the tile suction plate 4 to rotate, and the second gear ring 41 is in transmission connection with the first driven gear 11 to drive the tile pushing piece 6 to rotate.

[0029] Since mahjong is generally a four-player game, the mahjong machine generally has four tile suction plates 4 and four first driven gears 11 distributed on the outer periphery edge of the tile suction plate 21, and four driving motors 5 distributed on the frame 1, each driving motor 5 driving one tile suction plate 4 and one first driven gear 11. As the tile pushing piece 6 continuously pushes the mahjong tiles to the edge of the tile suction plate 21, the mahjong tiles will be sucked away by the tile suction plate 4 and enter the tile stacking mechanism. As the shuffling time is prolonged, the mahjong tiles on the tile suction plate 21 will become less and less, and the tile suction actions of the four tile suction plates 4 are random and have no sequence. As long as the mahjong tiles are pushed by the tile pushing piece 6 into the tile suction plate 4, they will be sucked away. Therefore, it is possible that one of the tile suction plates 4 completes the tile suction action before the other tile suction plates 4. Therefore, after the tile suction plate 4 sucks enough mahjong tiles, the driving motor 5 will stop working. At this time, the first driven gear 11 will stop transmitting power, but the meshing relationship between the first driven gear 11 and the first gear ring 631 still exists. Therefore, the first driven gear 11 cannot stop rotating, otherwise the tile pushing piece 6 cannot continue to shuffle. Therefore, the first driven gear 11 is installed on the first rotating shaft 12 through a one-way bearing in this embodiment. The first rotating shaft 12 is in transmission connection with the tile suction plate 4 and drives the first driven gear 11 to rotate due to the locking of the one-way bearing. The driving motor 5 stops working because the tile suction plate 4 sucks enough mahjong tiles. The first rotating shaft 12 stops rotating, and the first driven gear 11 rotates with the first gear ring 631 due to the free rotation of the one-way bearing.

[0030] The center area of the table board 3 is provided with a card inlet 301 and a dice disc 31, the dice disc 31 is lifted up and down to open or close the card inlet 301, in order to make the lifting movement of the dice disc 31 more stable, the rotating shaft 61 can be designed as a hollow shaft, the dice disc 31 passes through the rotating shaft 61, and the card pushing piece can also provide a certain degree of stability in the rotating process by cooperating with the dice disc 31.

[0031] In order to make the mahjong tiles more easily move to the edge of the shuffling disc 21 under the pushing of the card pushing piece 6, the upper surface of the shuffling disc 21 can be designed to extend downward from the center to the outer peripheral edge, which can be seen in detail in Figure 5 In the shuffling process, in addition to using centrifugal force to make the mahjong tiles move to the edge of the shuffling disc, the gravity of the mahjong tiles can also be used to move to the edge of the shuffling disc.

[0032] In order to further reduce the noise of shuffling, a shock-absorbing velvet pad 22 can be provided on the shuffling disc 21, the mahjong tiles pushed by the card pushing piece 6 move on the velvet pad 22, and the sound of the mahjong tiles hitting the velvet pad 22 when they are overturned is very small, and basically no noise is generated. Since the velvet pad 22 is provided, the resistance of the mahjong tiles moving will increase to a certain extent, in order to make the mahjong tiles move from the shuffling disc 21 to the suction disc 4 more smoothly, a blocking rib 211 that is beneficial to the mahjong tiles sliding to the suction disc 4 can be provided on the edge of the shuffling disc 21 at the through hole 20, and the top end surface of the blocking rib 211 is connected with the edge of the velvet pad 22 in a flush manner. Due to the action of gravity, the mahjong tiles will sink slightly when moving on the velvet pad 22, after the blocking rib 211 is provided, when the mahjong tiles move above the blocking rib 211, the blocking rib 211 will support the mahjong tiles to reduce the resistance of the mahjong tiles moving. In addition, in order to reduce noise, a velvet pad can also be provided on the suction disc 4.

[0033] In addition to the preferred embodiments described above, the present application has other embodiments, and those skilled in the art can make various changes and modifications according to the present application, as long as they do not deviate from the spirit of the present application, they should belong to the scope defined in the claims of the present application.
