In this embodiment, the inside of the control panel 5 is marked with the words East, South, West, and North, and multiple operation buttons are provided on the control panel 5, including a button to start the power module 6 and a button to control the jumping of the dice. The structure of the shuffling mechanism, the card return hole 3, the table 2, and the control panel 5 inside the mahjong machine box 1 is also a common structure in existing mahjong machines, and its functions and principles will not be described in detail.
[0017] Please see Figure 4 , Figure 5 and Figure 6 The mahjong machine housing 1 has a fixed support 7 located below the return hole 3 inside. The fixed support 7 includes a support arm 72 fixed to the inner wall of one side of the mahjong machine housing 1, and a vertical plate 71 is fixedly connected to one end of the support arm 72. An installation ring 73 is provided on the upper side of the vertical plate 71. A liner 74 is fixedly sleeved on the lower part of the outside of the installation ring 73. Several annularly distributed gear grooves 75 are provided inside the installation ring 73, and a shaft hole 76 penetrating the gear grooves 75 is provided on the top of the installation ring 73.
[0018] In this embodiment, the mounting ring 73 is fixed to the end of the support arm 72 by the vertical plate 71, and the far end of the support arm 72 is fixed to the inner wall of one side of the mahjong machine box 1. The liner 74 is used to support the rotating ring 82. The transition gear 81 is installed inside the gear groove 75, and the rotating shaft 85 is inserted into the shaft hole 76. The bottom end is fixedly connected to the transition gear 81.
[0019] Please see Figure 4 , Figure 5 and Figure 6 A power module 6 is provided on one side of the fixed support member 7. The power module 6 includes a forward and reverse motor 61 fixed on one side of the fixed support member 7, and a drive gear 62 is connected to the upper output shaft of the forward and reverse motor 61.
[0020] In this embodiment, starting the forward and reverse motor 61 can drive the drive gear 62 to rotate, and the drive gear 62 and the external gear 83 can drive the rotating ring 82 to rotate.
[0021] Please see Figure 4 , Figure 5 and Figure 6 The fixed support 7 is equipped with a transmission mechanism 8. The transmission mechanism 8 includes a rotating ring 82 sleeved on the outside of the mounting ring 73. The rotating ring 82 is located on the upper surface of the liner 74. The liner 74 supports the rotating ring 82, ensuring its rotational stability. At the same time, there is a gap between the rotating ring 82 and the outer surface of the mounting ring 73. The inner side wall of the rotating ring 82 is provided with internal teeth 84, and the outer side wall of the rotating ring 82 is provided with external teeth 83. The gear groove 75 is equipped with a transition gear 81. The transition gear 81 protrudes from the outside of the mounting ring 73 for installation, avoiding friction between the internal teeth 84 and the mounting ring 73. The top of the transition gear 81 is fixedly equipped with a synchronously rotating shaft 85, and the blade 4 is installed on the rotating shaft 85.
[0022] In this embodiment, after the power module 6 is started, the drive gear 62 rotates, thereby using the external gear 83 to drive the rotating ring 82 to rotate. The rotating ring 82 drives the transition gear 81 to rotate through the internal gear 84, and the transition gear 81 drives the rotating shaft 85 to rotate synchronously.
[0023] Please see Figure 4 , Figure 5 and Figure 6Above the fixed support 7, there is a blade plate 4 located on the lower side of the table 2. The power module 6 drives several blade plates 4 to open and close through the transmission mechanism 8. There are several blade plates 4, which are distributed in a ring around the card return hole 3. One end of the blade plate 4 is provided with a rotating head 41, which is fixedly connected to the top of the rotating shaft 85, so that the rotating head 41 rotates synchronously with the rotating shaft 85. The side of the blade plate 4 away from the rotating head 41 is provided with a surrounding hole edge 42, the side of the blade plate 4 close to the rotating head 41 is provided with a concave edge 43, and the far end of the blade plate 4 is provided with a convex edge 44.
[0024] In this embodiment, the number of blades 4 is preferably five. The five blades 4 can open or close synchronously under the action of the transmission mechanism 8. When the blade 4 is closed, the concave edge 43 of an adjacent blade 4 is attached to the surface of the convex edge 44 of another blade 4, thereby ensuring a better sealing effect on the return hole 3 after multiple blades 4 are closed. After multiple blades 4 are closed, the perimeter edge 42 on each blade 4 contacts the outer surface of the operating disc 5.
[0025] Please see Figure 4 , Figure 5 and Figure 6 A cover 9 is provided above the fixed support 7, and the blade 4 rotates on the upper surface of the cover 9.
[0026] In this embodiment, the protective cover 9 protects the transmission mechanism 8, preventing the mahjong tile from colliding with the gear and rotating ring 82, and also preventing damage to the mahjong tile. One side of the protective cover 9 is a small ring structure, and the other side is a large ring structure. The small ring is fitted outside the drive gear 62, and the large ring is fitted outside the fixed support 7, thereby covering the transmission mechanism 8.
[0027] The working principle and usage process of this utility model: When in use, the player plays mahjong on the upper surface of the table 2. After a game ends, the player can press the button on the control panel 5 to make the power module 6 move. Next, the power module 6 can drive the transmission mechanism 8 to rotate. The transmission mechanism 8 rotates outside the fixed support 7. Specifically, the forward and reverse motor 61 is started, which can drive the drive gear 62 to rotate. The drive gear 62 and the external gear 83 cooperate to drive the rotating ring 82 to rotate. The internal gear 84 on the inner side of the rotating ring 82 and the transition gear 81 rotate, so that the transition gear 81 drives the blade 4 to rotate through the rotating shaft 85, realizing the simultaneous opening and closing of several blades 4. Finally, after all the leaf plates 4 are opened, the card return hole 3 is exposed. The player pushes the mahjong tiles on the table 2 into the card return hole 3. After they are fully pushed in, the player presses the button on the control panel 5 to close it, thus using the mahjong machine box 1 to perform the mahjong tile shuffling operation.
