[0032] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0033] As Figures 1 to 8 shown, the card-dealing mechanism of the new type of second-time card-dealing mahjong machine in this embodiment includes a bracket 1. A spiral card-sending track groove 2 is arranged on the bracket 1. A card-sending mechanism 3 is arranged on the card-sending track groove 2. The card-playing end of the card-sending track groove 2 is connected to a card-lifting groove 4. A card-lifting mechanism 5 is arranged in the card-lifting groove 4. A card-sorting mechanism 6 is arranged between the card-sending track groove 2 and the card-lifting groove 4. The card-sorting mechanism 6 is used to send the mahjong tiles in the card-sending track groove 2 into the card-lifting groove 4 in two times. The card-sending mechanism 3 includes a first rotating motor 31 arranged at the center of the card-sending track groove 2. The output end of the first rotating motor 31 is connected to a planetary gear assembly 32. A support plate 33 is fixedly installed on the planetary gear assembly 32. A card-pushing arm 34 is fixedly connected to the support plate 33. A first signal magnet 35 is arranged on the card-pushing arm 34. The card-pushing end of the card-pushing arm 34 crosses from the inner side of the card-sending track groove 2 and extends into the card-sending track groove 2. The planetary gear assembly 32 drives the card-pushing arm 34 to rotate inside the card-sending track groove 2. Specifically, the bracket 1 serves as the basic framework of the entire card-lifting mechanism 5 and provides a stable installation platform for other components. On the bracket 1, a spiral card-sending track groove 2 is arranged. The card-sending track groove 2 is to ensure that the mahjong tiles can slide smoothly therein. The card-sending mechanism 3 is located on the card-sending track groove 2 and is used to push the mahjong tiles from the card-sending track groove 2 into the card-lifting groove 4. The first rotating motor 31 is connected to the planetary gear assembly 32 through a gear reduction device. Through the differential rotation of the planetary gears, the rotational motion of the first rotating motor 31 is converted into the complex trajectory motion required by the card-pushing arm 34. The first signal magnet 35 installed on the card-pushing arm 34 is used for the position control of the card-pushing of the card-pushing arm 34. During the card-sending process, the card-sending mechanism 3 will push the preset number of mahjong tiles each time according to the control. The card-playing end of the card-sending track groove 2 is connected to the card-lifting groove 4. The card-lifting groove 4 is the position where the mahjong tiles finally arrive and is used to store the mahjong tiles to be used by the players. Inside the card-lifting groove 4, there are slide rails and baffles to ensure that the mahjong tiles can be neatly arranged in the groove. Inside the card-lifting groove 4, a card-lifting mechanism 5 is arranged. The card-lifting mechanism 5 is responsible for lifting the mahjong tiles sent by the card-sending track groove 2 from the card-lifting groove 4 to the tabletop. The card-lifting mechanism 5 is also driven by a motor.

[0034] In order to implement the function of re - dealing the mahjong tiles, a tile - splitting mechanism 6 is arranged between the tile - delivering track groove 2 and the tile - placing groove 4. The tile - splitting mechanism 6 can adopt a robotic arm or other similar devices. When the mahjong tiles slide to the card - playing end of the tile - delivering track groove 2, they are divided into two groups and pushed into the tile - placing groove 4 in two times, and are respectively lifted to the tabletop through the tile - lifting mechanism 5. That is, the rapid, accurate and orderly re - dealing of mahjong tiles is realized, bringing a better gaming experience to players. That is, an ordinary mahjong machine uses a tile - lifting plate to lift the mahjong tiles onto the tabletop at one time, and players need to draw tiles multiple times before starting to play. The tile - placing mechanism of the mahjong machine in this embodiment deals the tiles in two times. When dealing the tiles for the first time, the 6 stacks of mahjong tiles that players need to draw before playing are lifted onto the tabletop, and players take away the 6 stacks of mahjong tiles from the tile - lifting plate at one time. After players take away the mahjong tiles from the tile - lifting plate, the tile - placing mechanism deals the tiles for the second time, sending the remaining mahjong tiles from the track to the tabletop. The re - dealing mechanism of this mahjong machine saves the tile - drawing time of players.

[0035] The tile - splitting mechanism 6 includes a first Hall sensor 63 arranged between the tile - delivering track groove 2 and the tile - delivering mechanism 3. When the first Hall sensor 63 senses the first signal magnet 35 on the tile - pushing arm 34, the tile - pushing arm 34 will pause the pushing. After the tile - lifting mechanism 5 completes the first tile - dealing and players take away the lifted mahjong tiles, the tile - pushing arm 34 continues to push the remaining mahjong tiles from the tile - delivering track groove 2 to the tile - lifting mechanism 5 for the second tile - dealing.

[0036] A first magnetic control plate 7 is arranged on the tile - delivering track groove 2. A second Hall sensor 71 and a third Hall sensor 72 are arranged on the first magnetic control plate 7. The first signal magnet 35 is cooperatively and inductively connected with the first Hall sensor 63, the second Hall sensor 71 and the third Hall sensor 72.

[0037] The second Hall sensor 71 is located at a specific position in the card delivery track groove 2. When the first signal magnet 35 on the card pushing arm 34 passes through this position as the card pushing arm rotates and moves, it will trigger the second Hall sensor 71 to generate an electrical signal, thereby achieving this. This signal may be used to confirm the position of the card pushing arm 34, the pushing speed, or as an intermediate detection point during the card splitting process. The third Hall sensor 72 is similar to the second Hall sensor 71 but is located at another position in the card delivery track groove 2, closer to the card outlet. When the first signal magnet 35 moves to this position, the trigger signal of the third Hall sensor 72 will serve as the key signal for the completion of the card splitting action. The control system determines whether enough mahjong tiles have been pushed for the first card placement based on this signal and decides whether to pause the pushing action of the card pushing arm 34 accordingly. The first Hall sensor 63 is installed between the card delivery track groove 2 and the card delivery mechanism 3. During the process of the card pushing arm 34 pushing mahjong tiles, when the first signal magnet 35 fixed on the card pushing arm 34 moves to a position corresponding to the first Hall sensor 63 during the rotation of the card pushing arm 34, the first Hall sensor 63 is triggered to generate an electrical signal. This electrical signal is then transmitted to the control system as feedback on the position or pushing progress of the card pushing arm 34. In this embodiment, when the control system receives the signal sent by the first Hall sensor 63, the first rotation motor 31 stops rotating, the card pushing arm 34 stops moving, and the mahjong tiles stop advancing. At this time, exactly 6 stacks of mahjong tiles reach the track outlet.

[0038] The card lifting mechanism 5 includes a fixed frame 51 installed on the bracket 1. A second rotation motor 52 is provided on the fixed frame 51. The output end of the second rotation motor 52 penetrates the fixed frame 51 and is connected to a card lifting rocker arm 53. A roller 54 is provided at the top of the card lifting rocker arm 53. A card lifting support plate 55 is rollingly connected to the roller 54. A card lifting plate 56 is provided at the top of the card lifting support plate 55. A sixth Hall sensor 57 is provided at the bottom of the card lifting plate 56. One side of the bottom of the card lifting plate 56 is hinged to a card lifting plate support 58. Specifically, the card lifting mechanism 5 is responsible for smoothly lifting the mahjong tiles from the card delivery track groove 2 to a position accessible to the player for the player to pick up the tiles. When the card lifting rocker arm 53 rotates, the roller 54 drives the card lifting support plate 55 to rise or fall along a preset track, ensuring that the mahjong tiles will not be subjected to excessive impact or vibration during the lifting and lowering process. At the same time, a sixth Hall sensor 57 is provided at the bottom of the card lifting plate 56. The sixth Hall sensor 57 can continuously monitor the mahjong tiles on the card lifting plate 56. When the player picks up the mahjong tiles, the sixth Hall sensor 57 cannot sense the mahjong tiles on the card lifting plate, and the card lifting plate 56 descends waiting for the second card placement.

[0039] A third signal magnet 531 is provided at the bottom of the card-lifting swing arm 53, and a fourth signal magnet 532 is provided at the position of the rotation axis of the card-lifting swing arm 53. Specifically, the fourth signal magnet 532 and the third signal magnet 531 are symmetrically arranged based on the rotation axis of the card-lifting swing arm 53. By respectively arranging the third signal magnet 531 and the fourth signal magnet 532 on both sides of the rotation axis, the control system can receive signals from two different positions, thereby more accurately judging the rotation state of the card-lifting swing arm 53.

[0040] A second magnetic control plate 511 is installed on the fixed frame 51, and a fourth Hall sensor 512 and a fifth Hall sensor 513 are provided on the second magnetic control plate 511. The third signal magnet 531 cooperates with the fourth Hall sensor 512 correspondingly, and the fourth signal magnet 532 cooperates with the fifth Hall sensor 513 correspondingly.

[0041] The overall working process is as follows: During the card shuffling process of the mahjong machine, after the card feeding mechanism 3 feeds a preset number of mahjong tiles (6 stacks in this embodiment) into the card feeding track groove 2, the card feeding mechanism 3 stops working, and the card feeding mechanism 3 adopts the conventional setting of an existing mahjong machine. The first rotating motor 31 rotates to drive the planetary gear assembly 32 to rotate, and the planetary gear assembly 32 drives the pushing arm 34 to move. The pushing arm 34 pushes the preset number of mahjong tiles in the card feeding track groove 2 to move forward along the track. When the first signal magnet 35 on the pushing arm 34 senses the first Hall sensor 63, the first rotating motor 31 stops rotating, the pushing arm 34 stops moving, and the mahjong tiles stop advancing. The card feeding mechanism 3 starts to act and continues to feed the mahjong tiles into the card feeding track groove 2. These mahjong tiles are located behind the pushing arm 34. When the required number of stacks of mahjong tiles is reached in the card feeding track groove 2, the card feeding mechanism 3 stops, and the mahjong machine enters the waiting state for card lifting. At this time, after the control system issues a card lifting instruction, the second rotating motor 52 rotates forward, the card-lifting swing arm 53 rotates forward, the card-lifting plate 56 rotates forward around the card-lifting plate axis, the free end of the card-lifting plate 56 descends. When the third signal magnet 531 on the card-lifting swing arm 53 senses the fourth Hall sensor 512, the second rotating motor 52 stops, and the free end of the card-lifting plate 56 descends in place. The first rotating motor 31 starts again, and the pushing arm 34 pushes the preset number of mahjong tiles in front of the pushing arm 34 to move forward along the card feeding track groove 2, that is, 6 stacks of mahjong tiles are like Figure 1As shown at position A, the mahjong tiles rise onto the lifting plate 56 along the track surface and the top surface of the lifting plate 56. When the first signal magnet 35 on the pushing arm 34 senses the third Hall sensor 72, the first rotating motor 31 stops, and the pushing arm 34 stops. The preset number of mahjong tiles have all reached the lifting plate 56. Then, the second rotating motor 52 rotates in reverse, the lifting rocker arm 53 rotates in reverse, the lifting plate 56 rotates in reverse around the lifting plate axis, and the free end of the lifting plate 56 rises. When the fourth signal magnet 532 on the lifting rocker arm 53 senses the fifth Hall sensor 513, the second rotating motor 52 stops, and the free end of the lifting plate 56 rises to the proper position. The preset number of mahjong tiles rise to the tabletop plane, completing the first tile placement.

[0042] Then, the first rotating motor 31 rotates, and the pushing arm 34 rotates. When the first signal magnet 35 on the pushing arm 34 senses the second Hall sensor 71, the first rotating motor 31 stops, and the pushing arm 34 stops. That is, the pushing arm 34 enters the preparatory position for the second tile placement, avoiding interference from the lifting plate 56 during the second tile placement. After the first tile placement is completed, the sixth Hall sensor 57 on the lifting plate 56 can sense the mahjong tiles on the lifting plate 56. When the player takes away the lifted mahjong tiles, the sixth Hall sensor 57 cannot sense the mahjong tiles on the lifting plate 56. The second rotating motor 52 rotates forward, the lifting rocker arm 53 rotates forward, the lifting plate 56 rotates forward around the lifting plate axis, the free end of the lifting plate 56 descends. When the third signal magnet 531 on the lifting rocker arm 53 senses the fourth Hall sensor 512, the second rotating motor 52 stops, and the free end of the lifting plate 56 descends to the predetermined position. Then, the first rotating motor 31 rotates, driving the pushing arm 34 to rotate and push the remaining mahjong tiles in the track along the card delivery track groove 2 forward. The remaining mahjong tiles are as Figure 1 shown at position B. The mahjong tiles rise onto the tabletop along the track surface and the top surface of the lifting plate 56. When the first signal magnet 35 on the pushing arm 34 senses the third Hall sensor 72, the first rotating motor 31 stops, and the pushing arm 34 stops. A part of the mahjong tiles have reached the tabletop, and the other mahjong tiles have all reached the top surface of the lifting plate 56. Then, the second rotating motor 52 rotates in reverse, the lifting rocker arm 53 rotates in reverse, the lifting plate 56 rotates in reverse around the lifting plate axis, and the free end of the lifting plate 56 rises. When the fourth signal magnet 532 on the lifting rocker arm 53 senses the fifth Hall sensor 513, the second rotating motor 52 stops, and the free end of the lifting plate 56 rises to the proper position. The remaining mahjong tiles all rise to the tabletop plane. The second tile placement is completed. At this time, the first rotating motor 31 continues to rotate, and the pushing arm 34 rotates. When the first signal magnet 35 on the pushing arm 34 senses the second Hall sensor 71, the first rotating motor 31 stops, and the pushing arm 34 stops. The mahjong machine enters the next round of shuffling cycle.

[0043] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
