Description

Technical Field

[0001] This utility model relates to the field of mahjong machine technology, specifically to a card-adding mechanism and a mahjong machine. Background Technology

[0002] Current automatic mahjong tables require two sets of magnetic mahjong tiles for players to use. One set is used on the table, while the other set is shuffled and stacked inside the table for later use. After a game, players simply operate the automatic mahjong table's program to push the completed magnetic tiles from the table back into the table. Then, the pre-stashed tiles inside the table are lifted onto the tabletop via a lifting mechanism, allowing players to continue playing. This cycle repeats quickly and effortlessly.

[0003] Because current mahjong machines use two sets of magnetic mahjong tiles and employ the traditional method of stacking all the tiles in front of the player, these automatic mahjong machines require four lifting mechanisms. This not only makes the structure of the automatic mahjong table's core (i.e., the mahjong main unit) more complex, but also prevents the space and weight of the mahjong main unit from being reduced. Furthermore, lifting the entire set of magnetic mahjong tiles onto the tabletop makes it difficult to keep the table tidy and provides dishonest players with the technical possibility to switch tiles or cheat.

[0004] In addition, there are now mahjong machines on the market that use only one set of mahjong tiles. Although they also use two tracks to serve the tiles in the center of the set, the efficiency of serving the tiles is not high because the two tracks share a single lifting platform.

[0053] Compared with the prior art, the beneficial effects of this utility model include the following:

[0054] In this invention, two symmetrically arranged conveying units transport mahjong tiles to corresponding lifting platforms. Specifically, a first conveying structure transports tiles to the first lifting platform, and a second conveying structure transports tiles to the second lifting platform. During the hand-drawing phase, the first and second lifting platforms move synchronously, initially at their highest positions. As they descend one level, each conveying unit pushes one mahjong tile above the first and second lifting platforms. Then, both platforms descend to two levels, and each conveying unit pushes another tile above the tiles that previously entered the lifting platforms, stacking them into a double-layered mahjong set. Both platforms then rise to their highest positions, raising all four tiles above the table for the player to draw. During the playing phase (after the hand is drawn), the first and second lifting platforms can move synchronously or independently. When the first and second lifting platforms move independently... At this time, the first and second lifting platforms move sequentially, one after the other, as follows: the lifting platform initially reaches its highest position, descends one level, and the conveyor belt transports a mahjong tile to the top of the lifting platform. The lifting platform then rises to its highest position for the player to grab, and the mahjong table always maintains a single mahjong tile available for the player to grab. The first and second lifting platforms cooperate to alternately raise the mahjong tile to the mahjong table, improving efficiency in loading a single deck of mahjong tiles while further enhancing the overall tile loading efficiency. The tile loading mechanism retrieves tiles as they are played in each game, rather than loading an entire deck of mahjong tiles at once. This eliminates the need for two decks, reducing weight and costs, and preventing cheating when stacking tiles. Attached Figure Description

[0073] Detailed Implementation

[0074] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0075] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0076] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0077] Current automatic mahjong tables require two sets of magnetic mahjong tiles for players to use. One set is used on the table, while the other set is shuffled and stacked inside the table for later use. After a game, players simply operate the automatic mahjong table's program to push the completed magnetic tiles from the table back into the table. Then, the pre-stashed tiles inside the table are lifted onto the tabletop via a lifting mechanism, allowing players to continue playing. This cycle repeats quickly and effortlessly.

[0078] Because current mahjong machines use two sets of magnetic mahjong tiles and employ the traditional method of stacking all the tiles in front of the player, these automatic mahjong machines require four lifting mechanisms. This not only makes the structure of the automatic mahjong table's core (the main unit) more complex but also prevents the main unit from being reduced in size and weight. Furthermore, lifting the entire magnetic mahjong set onto the table surface makes it difficult to keep the table tidy and provides an opportunity for dishonest players to cheat by switching tiles or using cheating methods.

[0079] In addition, there are mahjong machines on the market that use only one deck of mahjong tiles, but they only have two mahjong tile conveying units. They need to be combined with a shuffling structure to shuffle the tiles before feeding them, which results in low tile feeding efficiency.

[0080] Based on the aforementioned main problems, a revolutionary automatic mahjong machine with a completely new card-playing method and structure is needed to disrupt the industry. Based on this, an original mahjong machine card-lifting mechanism was designed.

[0081] Please see Figure 1-16 As shown, this utility model embodiment provides a mahjong machine 1000, which includes a table body 200, a tabletop 300, and a card-loading mechanism 100. The table body 200 has a receiving groove with its opening facing upward. The tabletop 300 covers the opening of the receiving groove and has a card-in / outlet 310 passing through its middle. The card-loading mechanism 100 is disposed in the receiving groove. The main utility model point of this utility model is the improvement of the card-loading mechanism 100. The card-loading mechanism 100 will be described below with reference to the specific drawings.

[0082] Please see Figure 1 , Figure 2 , Figure 3 and Figure 14 As shown, the card-loading mechanism 100 includes a card-lifting assembly 1, a card-conveying assembly 2, and a controller. The card-lifting assembly 1 includes two vertically parallel first lifting platforms 11 and second lifting platforms 12. Both the first lifting platforms 11 and the second lifting platforms 12 are located in the receiving slots of the table body 200 of the mahjong machine 1000 and are positioned corresponding to the card inlet / outlet 310 of the tabletop 300 of the mahjong machine 1000. The first lifting platform 11 moves vertically relative to the table body 200 under the driving action of the first driving member 17, and the second lifting platform 12 moves vertically relative to the table body 200 under the driving action of the second driving member 18.

[0083] It should be noted that the card inlet / outlet 310 is divided into one card outlet and two card inlets. In one embodiment of this utility model, the card outlet is located in the middle and is used for loading cards onto the first lifting platform 11 and the second lifting platform 12. The two card inlets are located on both sides of the card outlet and are used for the mahjong tiles 2000 on the table 300 to fall into the table body 200. More specifically, the card outlet is square and the card inlets are semi-circular.

[0084] The conveying plate assembly 2 includes a first conveying unit 21 and a second conveying unit 22. The first conveying unit 21 is located on one side of the first lifting platform 11 in the first direction, and the second conveying unit 22 is located on the other side of the second lifting platform 12 in the first direction. The first conveying unit 21 and the second conveying unit 22 are arranged in opposite directions symmetrically about the central vertical axis of the first lifting platform 11 and the second lifting platform 12 (the vertical central axis of the first lifting platform 11 and the second lifting platform 12 that are closely attached to one side of the plane).

[0085] The first conveying unit 21 is adapted to convey mahjong tiles to the first lifting platform 11, and the second conveying unit 22 is adapted to convey mahjong tiles to the second lifting platform 12, so that the first lifting platform 11 and the second lifting platform 12 can convey a set of mahjong tiles to the table 300 through the tile inlet / outlet 310.

[0086] The controller is electrically connected to the first conveying unit 21, the second conveying unit 22, the first drive unit 17, and the second drive unit 18 to control the simultaneous conveying of at least one mahjong tile by the first conveying unit 21 and the second conveying unit 22 to the first lifting platform 11 and the second lifting platform 12 during the hand-playing phase, and to the alternating conveying of at least one mahjong tile by the first conveying unit and the second conveying unit to the first lifting platform and the second lifting platform during the playing phase. The first direction is perpendicular to the vertical direction, and the central vertical axis lies within the vertical plane formed by the first direction and the vertical direction.

[0087] Further, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the top of the first lifting platform 11 has a first tile-holding section 111, and the top of the second lifting platform 12 has a third tile-holding section 121. The first tile-holding section 111 and the third tile-holding section 121 are respectively suitable for accommodating one mahjong tile. The table body 200 is provided with a tile-dispensing position, an upper tile-holding position and a lower tile-holding position in sequence along the vertical direction of the top of the first lifting platform 11 and the second lifting platform 12. The tile-dispensing position is set flush with the tile-in / out port 310. The upper tile-holding position is set corresponding to the first tile-holding section 111 and the third tile-holding section 121. The height of the lower tile-holding position is at least lower than the thickness of one mahjong tile on the first conveying unit 21 and the second conveying unit 22.

[0088] Since the first conveying unit 21 is configured corresponding to the first tile-loading section 111, and the second conveying unit 22 is configured corresponding to the third tile-loading section 121, both the first lifting platform 11 and the second lifting platform 12 can be moved to the tile-playing position, the upper tile-loading position, and the lower tile-loading position, respectively, so that the first conveying unit 21 and the second conveying unit 22 can respectively convey mahjong tiles to the first lifting platform 11 and the second lifting platform 12. In this way, two mahjong tiles 2000 can be loaded in two stacks.

[0089] Further, please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the first conveying unit 21 includes a first conveying structure 211 corresponding to the first card-loading part 111, and the second conveying unit 22 includes a second conveying structure 221 corresponding to the third card-loading part 121.

[0090] The first conveying structure 211 and the second conveying structure 221 are flush with the upper tile position, and the lower tile position is lower than the first conveying structure 211 and the second conveying structure 221. The first conveying structure 211 is adapted to convey mahjong tiles to the first lifting platform 11, and the second conveying structure 221 is adapted to convey mahjong tiles to the second lifting platform 12.

[0091] The first lifting platform 11 is adapted to descend from the playing position to the upper playing position to receive the first layer of single mahjong tiles conveyed by the first conveying structure 211 to the first playing section 111, and continue to descend to the lower playing position to receive the second layer of single mahjong tiles that fall from the first playing section 111 conveyed by the first conveying structure 211, with the second layer of single mahjong tiles stacked on the upper surface of the first layer of single mahjong tiles.

[0092] The second lifting platform 12 is adapted to descend from the playing position to the upper playing position to receive another single mahjong tile from the first layer, which is conveyed by the second conveying structure 221 to the third playing section 121, and to continue descending to the lower playing position to receive another single mahjong tile from the second layer, which is conveyed by the second conveying structure 221 to the third playing section 121.

[0093] In an optimized embodiment of this utility model, the first conveying unit 21 includes a first conveying structure 211, and the second conveying unit 22 includes a second conveying structure 221. The first conveying structure 211 conveys mahjong tiles 2000 to the first lifting platform 11, and the second conveying structure 221 conveys mahjong tiles 2000 to the second lifting platform 12, so that the first lifting platform 11 can convey at least one mahjong tile 2000 to the table 300 through the tile inlet / outlet 310, and the second lifting platform 12 can convey at least one mahjong tile 2000 to the table 300 through the tile inlet / outlet 310.

[0094] Thus, mahjong tiles 2000 are conveyed to the first lifting platform 11 via the first conveying structure 211 and to the second lifting platform 12 via the second conveying structure 221, so that the first lifting platform 11 can convey at least one mahjong tile 2000 to the table 300 via the tile inlet / outlet 310 and the second lifting platform 12 can convey at least one mahjong tile 2000 to the table 300 via the tile inlet / outlet 310, thereby enabling the single mahjong tile 2000 to be played.

[0095] Taking the delivery of two sets of mahjong tiles 2000 as an example, the delivery modes of the first lifting platform 11 and the second lifting platform 12 specifically include:

[0096] The first card-playing mode: The first lifting platform 11 and the second lifting platform 12 first move to the card-playing position. At this time, the first conveying structure 211 conveys a mahjong tile 2000 to the first lifting platform 11, and the second conveying structure 221 conveys a mahjong tile 2000 to the second lifting platform 12. Then the first lifting platform 11 and the second lifting platform 12 rise to the card-playing position respectively to complete the card-playing.

[0097] Furthermore, the table body 200 also includes a lower upper tile position, located below the upper upper tile position, and the distance between the lower upper tile position and the conveying structures (first conveying structure 211 and second conveying structure 221) is greater than or equal to the sum of the heights of one mahjong tile 2000. Thus, the first conveying structure 211 can continuously convey two mahjong tiles 2000 to the first lifting platform 11, and the second conveying structure 221 can continuously convey two mahjong tiles 2000 to the second lifting platform 12.

[0098] In another optimized embodiment of this utility model, a set of mahjong tiles 2000 is simultaneously conveyed to the first lifting platform 11 and the second lifting platform 12 via the first conveying structure 211 and the second conveying structure 221, respectively. This allows for shuffling of the tiles while they are being played, thereby reducing or even eliminating the shuffling time of the mahjong tiles 2000 within the mahjong machine 1000 and improving the efficiency of playing the tiles.

[0099] In addition, it is important to emphasize that the card-dealing mechanism 100 can only deal a portion of the mahjong tiles 2000 at a time. This means that the tiles are dealt as needed in each game, rather than dealing the entire set of mahjong tiles at once. This reduces the need for two sets of mahjong tiles, thus reducing weight and costs, and also prevents players from cheating when arranging the tiles.

[0100] It should be noted that in this utility model, when controlling either the first conveying structure 211 or the second conveying structure 221 to convey mahjong tiles 2000 to the lifting platform, the order of tile feeding of the first conveying structure 211 and the second conveying structure 221 can be alternated, or one of them can be selected to feed tiles individually.

[0101] When the first conveying structure 211 and the second conveying structure 221 simultaneously convey mahjong tiles 2000 to the first lifting platform 11 and the second lifting platform 12 in different / same order, the different order means that the first conveying structure 211 and the second conveying structure 221 convey the tiles in different sequences, and the same order means that the first conveying structure 211 and the second conveying structure 221 convey the tiles in a preset sequence.

[0102] More specifically, in a preferred embodiment of this utility model, when controlling the first conveying structure 211 and the second conveying structure 221 to deliver the mahjong tiles 2000, the first conveying structure 211 delivers mahjong tiles 2000 to the first lifting platform 11, and the second conveying structure 221 simultaneously delivers mahjong tiles 2000 to the second lifting platform 12. When the first lifting platform 11 rises to its highest position (the tile-delivering position), the upper surface of the first lifting platform 11 is basically flush with the surface 300 of the mahjong table. When the first lifting platform 11 descends one level, its upper surface is parallel to or slightly lower than the conveyor rail. The first lifting platform 11 descends to a height of two layers, its upper surface being more than the thickness of one mahjong tile below the conveyor track; similarly, when the second lifting platform 12 rises to its highest point, its upper surface is basically flush with the mahjong tabletop 300; the second lifting platform 12 descends to a height of one layer, its upper surface being parallel to or slightly below the conveyor track; the second lifting platform 12 descends to a height of two layers, its upper surface being more than the thickness of one mahjong tile below the conveyor track, thus enabling the first lifting platform 11 and the second lifting platform 12 to move synchronously or independently to load tiles.

[0103] For example, at the start of a mahjong game, the player pushes the mahjong tiles on the table into the mahjong shuffling chamber. The shuffling wheel rotates, which in turn drives the mahjong tiles 2000 to approach the suction wheel 2d and suck them into the conveyor track 2a. Finally, the mahjong tiles are simultaneously pushed to the tabletop 300 of the mahjong table by the first lifting platform 11 and the second lifting platform 12. The player then picks up the mahjong tiles in turn to start the game.

[0104] During the hand phase (each player typically draws 13 mahjong tiles as their hand), the first and second lifting platforms 11 and 12 move synchronously, initially at their highest position (the discarding position). By descending one level (i.e., to the upper discarding position), each of the two conveyor tracks 2a pushes one mahjong tile above the first and second lifting platforms 11 and 12. The first and second lifting platforms 11 and 12 simultaneously descend to two levels (i.e., to the lower discarding position), and each of the two conveyor tracks 2a pushes another mahjong tile above the first layer of mahjong tiles that previously entered the first and second lifting platforms 11 and 12, causing the two mahjong tiles to stack up to form two layers. Then, the first and second lifting platforms 11 and 12 rise to their highest position (the discarding position), raising the four mahjong tiles from the two layers to above 300 degrees on the table for the players to draw.

[0105] During the card-playing phase (after the cards are drawn), the first lifting platform 11 and the second lifting platform 12 can move synchronously or independently.

[0106] In a more preferred embodiment, the first lifting platform 11 and the second lifting platform 12 move independently. In this case, the first lifting platform 11 and the second lifting platform 12 move sequentially, one after the other, as follows: when the initial position of the first lifting platform 11 and the second lifting platform 12 is at its highest point, the first lifting platform 11 or the second lifting platform 12 descends one level to the upper position, and the first transmission belt 2c5 conveys a mahjong tile to the first lifting platform 11 or the second lifting platform 12. of Above, either the first lifting platform 11 or the second lifting platform 12 raises the mahjong tile to the highest point (the playing position) for the player to draw. The mahjong table surface 300 always maintains one mahjong tile for the player to draw. This coordinated movement of the first lifting platform 11 and the second lifting platform 12, alternately raising the mahjong tile to the table surface 300, results in higher efficiency in drawing tiles.

[0107] In this way, the first conveying structure 211 and the second conveying structure 221 work together to complete the task of placing a set of mahjong tiles. The advantage of this is that during the game, the mahjong tiles are raised one or more from the tile entry and exit points 310 of the mahjong table, and the players take turns to draw them. This not only enables a fast game with one set of tiles, but also effectively prevents players from cheating when drawing tiles.

[0108] In one embodiment of this utility model, when the first conveying unit 21 includes a first conveying structure 211 corresponding to the first card-loading section 111, and the second conveying unit 22 includes a second conveying structure 221 corresponding to the third card-loading section 121, during the hand-playing stage, the controller controls the first conveying structure 211 and the second conveying structure 221 to simultaneously convey mahjong tiles 2000 to the first lifting platform 11 and the second lifting platform 12, respectively; the order of the four mahjong tiles in the two layers raised above the tabletop 300 for the player to grab is random. During the playing stage, the controller controls the first conveying structure 211 and the second conveying structure 221 to convey mahjong tiles 2000 to the first lifting platform 11 and the second lifting platform 12 in an alternating order, which can be a preset order or a random alternating order.

[0109] Further, please refer to Figure 1 , 7As shown in Figure 8, in another embodiment of this utility model, the top of the first lifting platform 11 also has a second upper tile section 112 stacked and distributed directly below the first upper tile section 111, and the top of the second lifting platform 12 also has a fourth upper tile section 122 stacked and distributed directly below the third upper tile section 121. The first upper tile section 111, the second upper tile section 112, the third upper tile section 121 and the fourth upper tile section 122 are each suitable for accommodating a mahjong tile; the lower tile positions are correspondingly arranged with the second upper tile section 112 and the fourth upper tile section 122.

[0110] The first conveying unit 21 is provided corresponding to the first card-loading section 111 or the second card-loading section 112, and the second conveying unit 22 is provided corresponding to the third card-loading section 121 or the fourth card-loading section 122.

[0111] Both the first lifting platform 11 and the second lifting platform 12 can be moved to the card-playing position, the upper card-playing position, and the lower card-playing position, so that the first conveying unit 21 and the second conveying unit 22 can respectively convey mahjong tiles to the first lifting platform 11 and the second lifting platform 12.

[0112] At this time, please refer to Figure 7 , 8 As shown, preferably, the first conveying unit 21 includes a first upper conveying structure 212 and a first lower conveying structure 213, and the second conveying unit 22 includes a second upper conveying structure 222 and a second lower conveying structure 223; the first upper conveying structure 212 is disposed above the first lower conveying structure 213, and the second upper conveying structure 222 is disposed above the second lower conveying structure 223.

[0113] The first upper conveying structure 212 and the second upper conveying structure 222 are flush with the upper tablet position, and the first lower conveying structure 213 and the second lower conveying structure 223 are flush with the lower tablet position.

[0114] The first upper conveying structure 212 is set to correspond to the first card-loading section 111, and the first lower conveying structure 213 is set to correspond to the fourth card-loading section 122 or the second card-loading section 112.

[0115] The second upper conveying structure 222 is set to correspond to the third card-loading section 121, and the second lower conveying structure 223 is set to correspond to the second card-loading section 112 or the fourth card-loading section 122.

[0116] The controller is adapted to control the first lifting platform 11 to receive two layers of mahjong tiles from the first upper conveying structure 212 and the first lower conveying structure 213 in different / same tile-playing order;

[0117] The controller is adapted to control the second lifting platform 12 to receive the other two layers of mahjong tiles conveyed from the second upper conveying structure 222 and the second lower conveying structure 223 in different / same tile-playing order.

[0118] Specifically, the first conveying unit 21 includes a first upper conveying structure 212 corresponding to the first card-loading part 111 and a first lower conveying structure 213 corresponding to the fourth card-loading part 122 or the second card-loading part 112. The second conveying unit 22 includes a second upper conveying structure 222 corresponding to the third card-loading part 121 and a second lower conveying structure 223 corresponding to the fourth card-loading part 122 or the second card-loading part 112. The first upper conveying structure 212 is located above the first lower conveying structure 213, and the second upper conveying structure 222 is located above the second lower conveying structure 223.

[0119] In one connection method, the first lifting platform 11 corresponds to the first upper conveying structure 212 and the first lower conveying structure 213, with the first upper conveying structure 212 positioned above the first lower conveying structure 213. The second lifting platform 12 corresponds to the second upper conveying structure 222 and the second lower conveying structure 223, with the second upper conveying structure 222 positioned above the second lower conveying structure 223. The first upper conveying structure 212 and the second upper conveying structure 222 are flush with the upper level positions, and the first lower conveying structure 213 and the second... The lower conveyor structure 223 is flush with the lower upper tile position; the controller is adapted to control the first lifting platform 11 to receive two layers of mahjong tiles from the first tile-laying section 111 of the first upper conveyor structure 212 and the second tile-laying section 112 of the first lower conveyor structure 213 in different / same tile-laying order; the controller is also adapted to control the second lifting platform 12 to receive two more layers of mahjong tiles from the third tile-laying section 121 of the second upper conveyor structure 222 and the fourth tile-laying section 122 of the second lower conveyor structure 223 in different / same tile-laying order.

[0120] The different card-issuing orders refer to multiple conveying structures issuing cards in different sequences, while the same card-issuing order refers to multiple conveying structures issuing cards in a preset sequence.

[0121] More specifically, for example, the four conveying structures include a first upper conveying structure 212, a second upper conveying structure 222, a first lower conveying structure 213, and a second lower conveying structure 223. When controlling the four conveying structures to deliver tiles simultaneously, the mahjong tiles 2000 can be delivered in different sequences. For example, during the first delivery, the first upper conveying structure 212, the second upper conveying structure 222, the first lower conveying structure 213, and the second lower conveying structure 223 can be selected sequentially; and during the second delivery, the second upper conveying structure 222 and the first lower conveying structure 213 can be selected sequentially. The game proceeds by sequentially placing tiles on the second lower conveyor structure 223 and the first upper conveyor structure 212, and then sequentially placing tiles on the second upper conveyor structure 222, the first upper conveyor structure 212, the second lower conveyor structure 223, and the first lower conveyor structure 213 during the third tile placement. In the fourth tile placement, two of the following structures are selected to place tiles twice consecutively: the first upper conveyor structure 212, the second upper conveyor structure 222, the first lower conveyor structure 213, and the second lower conveyor structure 223. This process continues until all 2000 tiles of a mahjong set have been placed, ending one game.

[0122] The mahjong tiles 2000 can be delivered in the same order. This can be done by selecting the order of delivery from the first upper delivery structure 212, the second upper delivery structure 222, the first lower delivery structure 213, and the second lower delivery structure 223 until all 2000 tiles are delivered, thus ending a game. Alternatively, the tiles can be delivered in the order of delivery from the second upper delivery structure 222, the first upper delivery structure 212, the second lower delivery structure 223, and the first lower delivery structure 213. Another option is to deliver the tiles in the order of delivery from two of the first upper delivery structure 212, the second upper delivery structure 222, the first lower delivery structure 213, and the second lower delivery structure 223, each delivering tiles twice consecutively. Alternatively, the tiles can be delivered in any other preset order.

[0123] Thus, when a set of mahjong tiles 2000 falls into the machine body after a game, the mahjong tiles 2000 can be shuffled. When the conveying structure adds tiles, it randomly selects one mahjong tile 2000. Therefore, whether the tiles are added in different or the same order, the addition of tiles is random, thus achieving the effect of shuffling the tiles.

[0124] For details, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, in one embodiment of this utility model, the tile-lifting assembly 1 further includes an upper stop frame 13, which is disposed between the first conveying unit 21 and the second conveying unit 22, and is disposed corresponding to the first lifting platform 11 and the second lifting platform 12. The upper stop frame 13 is disposed through the vertical direction, so that the first lifting platform 11 can move in and out of the first lifting platform 11 in the vertical direction and the second lifting platform 12 can move in and out of the first lifting platform 11 in the vertical direction. The upper stop frame 13 has a first tile inlet 131 on its side wall near the first conveying unit 21, so that the first conveying unit 21 can convey mahjong tiles 2000 to the first lifting platform 11. The upper stop frame 13 has a second tile inlet 132 on its side wall near the second conveying unit 22, so that the second conveying unit 22 can convey mahjong tiles 2000 to the second lifting platform 12.

[0125] In this way, the mahjong tiles 2000 can be limited by the side wall of the upper stop frame 13, which can prevent the mahjong tiles 2000 from being over-transported and causing at least a large part of the mahjong tiles 2000 to move outside the first lifting platform 11 and the second lifting platform 12, which would cause them to be flipped over or affect the loading of other mahjong tiles 2000 during the loading process.

[0126] Further, please refer to Figure 5 and Figure 6 As shown, the upper stop frame 13 has an upper partition plate 14 extending vertically in the middle, which divides the upper stop frame 13 into a first stop portion 133 corresponding to the first tile-laying portion 111 and a second stop portion 134 corresponding to the second tile-laying portion 112. The first stop portion 133 and the second stop portion 134 respectively have a first tile-entry port 131 and a second tile-entry port 132 arranged parallel to each other in the first direction. In this way, the upper partition plate 14 further limits the mahjong tiles 2000, so that multiple mahjong tiles 2000 can be neatly laid out.

[0127] Further, please refer to Figure 11 and Figure 12 As shown, the plate-raising assembly 1 also includes a lower stop 15 and a lower partition plate 16, wherein:

[0128] The lower stop frame 15 is symmetrically arranged in the opposite direction directly below the upper stop frame 13. The lower stop frame 15 is located between the first conveying unit 21 and the second conveying unit 22, and is respectively arranged corresponding to the first lifting platform 11 and the second lifting platform 12. The lower stop frame 15 is arranged through the vertical direction so that the first lifting platform 11 and the second lifting platform 12 can move in and out of the first lifting platform 11 and the second lifting platform 12 respectively in the vertical direction. The lower stop frame 15 has a third card inlet 151 on the side wall near the first conveying unit 21 so that the first conveying unit 21 can convey mahjong tiles to the first lifting platform 11. The lower stop frame 15 has a fourth card inlet 152 on the side wall near the second conveying unit 22 so that the second conveying unit 22 can convey mahjong tiles to the second lifting platform 12.

[0129] The lower partition plate 16 extends along the vertical direction and is disposed in the middle of the lower stop frame 15 and below the upper partition plate 14, so as to divide the lower stop frame 15 along the first direction into a third stop portion 153 corresponding to the second upper plate portion 112 and a fourth stop portion 154 corresponding to the fourth upper plate portion 122. The third stop portion 153 and the fourth stop portion 154 are respectively provided with a third plate inlet 151 and a fourth plate inlet 152 that are offset along the first direction.

[0130] For details, please refer to Figure 1 , Figure 2 , Figures 3 to 4 As shown, the first conveying structure 211 and the second conveying structure 221 have the same structure. The first conveying structure 211 includes a conveying track 2a, at least one transfer plate 2b, and a drive module 2c. The conveying track 2a is bent, and its output end is located corresponding to the first lifting platform 11. The transfer plate 2b is located at the bend of the conveying track 2a, and part of the transfer plate 2b is pressed onto the conveying track 2a. The drive module 2c is used to drive the mahjong tiles 2000 on the conveying track 2a to move towards the output end. The controller is electrically connected to the drive module 2c. In this way, the corner space of the main body of the mahjong machine 1000 can be effectively utilized, and the bending problem of the conveying path can be cleverly solved by the transfer plate 2b, avoiding the mahjong tiles 2000 from getting stuck at the corner.

[0131] It should be noted that in this utility model, the number of transfer plates 2b in the first conveying structure 211 can be set to one or two, depending on the specific requirements.

[0132] Further, please refer to Figures 1 to 4As shown, the drive module 2c includes a drive wheel 2c1, a first driven wheel 2c2, a second driven wheel 2c3, a third driven wheel 2c4, a first transmission belt 2c5, and a third drive component 2c6. The drive wheel 2c1 is located at the input end of the conveying track 2a; the first driven wheel 2c2 is located on the conveying track near the drive wheel directly below it; the second driven wheel 2c3 is located at the bend of the conveying track 2a; and the third driven wheel 2c4 is located at the output end of the conveying track 2a.

[0133] The first transmission belt 2c5 includes a first transmission section and a second transmission section connected together. The first transmission section is located on the lower side of the conveying track 2a and is sequentially sleeved on the outside of the driving wheel 2c1, the first driven wheel 2c2, the first driven wheel 2c3, and the third driven wheel 2c4. The second transmission section is located on the upper side of the conveying track 2a and is sequentially sleeved on the outside of the third driven wheel 2c4, the transfer plate 2b, and the driving wheel 2c1. The third driving member 2c6 is drivenly connected to the driving wheel 2c1 to drive the driving wheel 2c1 to rotate, so that the driving wheel 2c1 drives the first driven wheel 2c2, the second driven wheel 2c3, the second driven wheel 2c4, and the transfer plate 2b to rotate through the first transmission belt 2c5. The controller is electrically connected to the third driving member 2c6.

[0134] It should be noted that in this utility model, the number of second driven wheels 2c3 is not limited; it can be set according to the turning angle requirements, and can include one, two, three, etc. For details, please refer to [link / reference needed]. Figures 1 to 4 In one embodiment of this utility model, two second driven wheels 2c3 are provided.

[0135] Further, please refer to Figures 1 to 4 As shown, the mahjong tiles 2000 are magnetic mahjong tiles. The first conveying structure 211 and the second conveying structure 221 each include a tile-collecting wheel 2d and a second transmission belt 2e. The tile-collecting wheel 2d is located at the input end of the conveying track 2a and is positioned away from the conveying track 2a relative to the drive wheel 2c1, used to collect the mahjong tiles 2000 within the table body 200. The second transmission belt 2e is sleeved around the outer periphery of the tile-collecting wheel 2d and the drive wheel 2c1, so that the drive wheel 2c1 drives the tile-collecting wheel 2d to rotate. Thus, the tile-collecting wheel 2d rotates through the transmission of the drive wheel 2c1, allowing the collected mahjong tiles 2000 to be conveyed onto the conveying track 2a.

[0136] The conveying process of the mahjong tiles 2000 is as follows: the third driving component drives the driving wheel 2c1 to rotate, thereby driving the first driven wheel 2c2, the second driven wheel 2c3, the third driven wheel 2c4, the first transmission belt 2c5, the transfer plate 2b, the second transmission belt 2e, and the tile-collecting wheel 2d to rotate. Each tile-collecting wheel 2d first picks up the mahjong tiles 2000 that have fallen into the table body 200 of the mahjong machine 1000 one by one, and then conveys the picked-up mahjong tiles 2000 one by one to the input end of the conveying track 2a through the rotation. The mahjong tile 2000 at one end moves toward the bend of the conveyor track 2a under the transmission action of the first transmission belt 2c5 and the pushing action of the next mahjong tile 2000. When the mahjong tile 2000 moves to the bend of the conveyor track 2a, part of the mahjong plate is located on the periphery of the transfer plate 2b, and turns under the action of the transfer plate 2b, and then moves toward the output end of the conveyor track 2a until the mahjong tile 2000 moves to the output end, and then moves to the lifting platform under the action of the first transmission belt 2c5.

[0137] Specifically, in some other embodiments of this utility model, the mahjong tiles 2000 are non-magnetic and can be made of materials commonly used in conventional mahjong tiles 2000, such as wood, bamboo, jade, stone, or plastic.

[0138] Specifically, in this utility model, the arrangement of the third driving component is not limited. More specifically, in one embodiment of this utility model, the third driving component is a drive motor.

[0139] Specifically, in this utility model, the arrangement of the first driving member 17 and the second driving member 18 is not limited.

[0140] For example, in one embodiment of this utility model, please refer to Figure 14 , 15 As shown in Figure 16, the first driving component 17 includes a first gear 171, a second gear 172, a third gear 173, and a lifting frame 174. The first gear 171 is mounted on the output shaft of the third driving component 2c6 via a transmission shaft. The second gear 172 meshes directly above the first gear 171. The third gear 173 is mounted on the side of the second gear 172 facing away from the first gear 171 via a first crank 1721. One side of the first crank 1721 is coaxially driven with the center of the second gear 172, and the other side is coaxially driven with the center of the third gear 173. A second crank 1731 is mounted on the side of the third gear 173 facing away from the second gear 172, and its bottom end is coaxially driven with the center of the third gear 173. The top end of the second crank 1731 is connected to the lifting frame 174, and a first lifting platform 11 is mounted on the top of the lifting frame 174. Thus, the first lifting platform 11 moves up and down via the drive of the third driving component 2c6.

[0141] In another embodiment of this utility model, the first driving member 17 and the second driving member 18 have completely identical structures, and the installation arrangement of the first driving member 17 and the second driving member 18 is as follows: Figure 14 , Figure 15 and Figure 16 As shown.

[0142] More specifically, in one embodiment of this utility model, the first driving component 17 and the second driving component 18 are stepper motors. Compared with DC motors that require Hall sensors, stepper motors can control the movement of the first lifting platform 11 and the second lifting platform 12 by combining the motion algorithm in the controller. Furthermore, through PWM signal control, the stepper motor can directly run the specified stroke without relying on Hall sensors as a reference for the movement stroke. At the same time, it can also realize the motion control of the first lifting platform 11 and the second lifting platform 12 during the license plate issuance process, such as slow lifting and slow lowering, damped motion and other high-order requirements.

[0143] The specific process of the vehicle registration method of the registration agency in this embodiment is as follows:

[0144] First, the first conveying unit 21 and the second conveying unit 22 in the mahjong machine pick up the mahjong tiles 2000 inside the table body 200 of the mahjong machine.

[0145] Specifically, the mahjong tiles 2000 are first picked up by the suction wheel 2d and transported to the conveyor track 2a. Then, the mahjong tiles are transported to the output end of the conveyor track 2a by the first transmission belt 2c5 and the transfer plate 2b.

[0146] Next, the first conveying unit 21 is driven to convey mahjong tiles to the first lifting platform 11, and the second conveying unit 22 is driven to convey mahjong tiles to the second lifting platform 12. In this step, the controller can control the first conveying unit 21 and the second conveying unit 22 to randomly add tiles, so that the tiles can be shuffled at the same time as being added, thereby reducing or even eliminating the shuffling time.

[0147] It should be noted that in this step, the random card-dispensing by the first conveying unit 21 and the second conveying unit 22 also requires the movement of the first lifting platform 11 and the second lifting platform 12 between the card-dispensing position, the card-dispensing position, and the bottom card-dispensing position. The specific card-dispensing mode has been explained above and will not be repeated here.

[0148] Finally, the controller drives the first lifting platform 11 to move upward to the tile inlet / outlet 310 via the first driving component 17 in the mahjong machine 1000, and drives the second lifting platform 12 to move upward to the tile inlet / outlet 310 via the second driving component 18 in the mahjong machine 1000, so as to control the first conveying unit 21 and the second conveying unit 22 to simultaneously convey at least one mahjong tile to the first lifting platform 11 and the second lifting platform 12 respectively during the hand stage, and to the first conveying unit 21 and the second conveying unit 22 to alternately convey at least one mahjong tile to the first lifting platform 11 and the second lifting platform 12 during the playing stage.

[0149] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
