Description

TECHNICAL FIELD

[0001] The present application belongs to the field of mahjong game equipment, and relates to a mahjong machine, in particular to a tile stacking device for stacking and transporting mahjong tiles, a tile feeding mechanism containing the tile stacking device, and a mahjong machine containing the tile feeding mechanism. BACKGROUND

[0002] The mahjong machine is a device that can avoid user's shuffling and dealing operations, and is convenient for multiple users to play simultaneously. It usually has a shuffling mechanism for shuffling mahjong tiles, a tile feeding mechanism for stacking and feeding the shuffled mahjong tiles to the tabletop for use, an operation panel mechanism for user to input operation instructions, and a table frame for overall support.

[0003] Among them, the tile feeding mechanism needs to be set up respectively for each user. For example, a common mahjong machine is used by four users, and accordingly, four sets of tile feeding mechanisms need to be set up. Each set of tile feeding mechanism also needs to realize the functions of tile stacking, tile storage, tile pushing, and tile lifting.

[0004] Among them, the tile stacking device is an important structure for realizing tile stacking. For example, a mahjong machine head assembly disclosed in Chinese Patent No. 202121989822.9 includes a head shell, a tile pushing assembly and a cam assembly arranged on the head shell, and a tile receiving seat arranged on the head shell. The tile pushing assembly includes a pushing head push rod and a first rolling bearing. The first rolling bearing is arranged on the pushing head push rod. The cam assembly is provided with a curved ring groove. The first rolling bearing is embedded in the curved ring groove and is in sliding fit with the curved ring groove. When the cam assembly rotates, the cam assembly drives the pushing head push rod to rotate in the vertical direction.

[0005] In the above-mentioned head assembly, the pushing head push rod is vertically arranged. When the cam assembly rotates, the pushing head push rod and the pushing head swing in the vertical direction. The pushing head has a tile pushing surface for pushing the mahjong tiles on the tile receiving seat into the tile storage groove. The tile pushing surface is inclined upward in the initial position. As the pushing head swings in the tile pushing direction, the tile pushing surface changes position slowly and pushes the side wall of the mahjong tile, realizing tile pushing.

[0006] In actual use, it is found that the above-mentioned head assembly has relatively large noise and slow action due to fast tile pushing. In addition, in the initial position of the tile pushing surface, the mahjong tile may be turned over when it slides along the tile pushing surface into the tile receiving seat during the tile feeding process, resulting in failure of tile stacking. Or, the next mahjong tile may be inclined and stuck between the previous mahjong tile and the pushing head. At this time, the action of the pushing head cannot normally stack the next mahjong tile on the previous mahjong tile, resulting in that the tile storage groove cannot normally feed the tiles, thereby affecting the normal work of the mahjong machine. SUMMARY

[0007] To solve the above problems, the application provides a stacking device capable of making mahjong stacking and transportation more smooth, efficient and low noise, a mahjong feeding mechanism containing the stacking device and a mahjong machine containing the mahjong feeding mechanism.

[0014] The mahjong stacking device provided by the application can also have the following technical features: the card pushing push rod is horizontally arranged and can swing horizontally along with the rotation of the card pushing driving wheel, so that the card pushing block can reciprocate horizontally in a vertical posture, and the card pushing is realized.

[0015] The mahjong stacking device provided by the application can also have the following technical features: the card pushing unit further comprises an auxiliary push rod arranged horizontally on one side of the card pushing push rod, one end of the auxiliary push rod is hinged to the frame, and the other end of the auxiliary push rod is arranged on the card pushing block.

[0040] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the following describes the card-playing mechanism and mahjong machine of the present invention in detail with reference to the embodiments and accompanying drawings.

[0041] <Example>

[0042] Figure 1 This is a structural diagram of the mahjong machine from one angle in this embodiment. Figure 2 This is a structural diagram of the mahjong machine without the table and outer frame in an embodiment of the present invention.

[0043] like Figure 1 and Figure 2As shown, this embodiment provides a mahjong machine 100 for automatically shuffling and loading mahjong tiles, including a shuffling mechanism 107, a loading mechanism 101, an operation panel mechanism 102, and a table frame mechanism 103.

[0044] The table frame mechanism 103 includes an outer frame 104, a tabletop 105 mounted on the outer frame 104, and a lower frame 106 that supports the tabletop 105 and other mechanisms. The bottom of the lower frame 106 is provided with table legs for supporting the ground.

[0045] The control panel mechanism 102 is raised and lowered in the middle of the table 105. It contains a control module that controls the operation of various parts of the mahjong machine 100. The top is equipped with operation buttons for users to input operation commands.

[0046] The shuffling mechanism 107 is located in the middle of the table 105 and is used to shuffle the mahjong tiles after use. It includes a shuffling plate for carrying and rotating the mahjong tiles.

[0047] The mahjong machine 100 of this embodiment can be used by four users at the same time, and is provided with four card-adding mechanisms 101, which are located at the four corners of the lower frame 106 respectively.

[0048] Figure 3 This is a structural diagram of the license plate issuing mechanism from one angle in this embodiment; Figure 4 This is a structural diagram of the card stacking device installed on the card storage tray in an embodiment of the present invention.

[0049] like Figure 3 and Figure 4 As shown, the card-issuing mechanism 101 includes a card-supplying device 10, a card-stacking device 20, a card-storing device 30, a card-pushing device 40, and a card-raising device 50.

[0050] The tile feeding device 10 includes a tile-collecting wheel for picking up mahjong tiles and a belt assembly for transporting the tiles. The tile-collecting wheel is located at the shuffling port of the tile feeding device 10, and the belt assembly is located at the tile feeding port of the tile feeding device 10. It is used to pick up mahjong tiles from the shuffling mechanism 107 and feed them to the device. The tile-stacking device 20 is located at the tile feeding port of the tile feeding device 10 and is used to stack the single mahjong tiles fed by the tile feeding device 10, forming stacks of two tiles each. These stacks are then stored sequentially in the tile storage device 30.

[0051] The card storage device includes a card storage tray 31, which is approximately square in shape, with one corner notched and the other three corners rounded. Vertically upward-extending baffles are provided along the edges, and the center protrudes upwards, forming an approximately arc-shaped card storage groove 311 between the baffles and the central protrusion. A support column is also provided at the bottom of the card storage tray 31, which is mounted on the lower frame 106.

[0052] The card storage slot 311 is used to store card stacks and has a card inlet 311A ​​and a card outlet 311B. The card stacking device 20 is installed at the card inlet 311A, and a card lifting device 50 is installed at the card outlet 311B. The card lifting device 50 has a support plate 51, and a card outlet slot 105A corresponding to the position and matching the shape of the support plate 52 is provided on the table 105. The support plate 51 swings in the card outlet slot 105A. When the support plate 52 swings downward until it reaches the lowest position, it connects the card storage slot 311 and the table 105. When the support plate 52 swings upward until it reaches the highest position, it closes the card outlet slot 105A. The entire support plate 52 protrudes from the card outlet slot 105 onto the table, and the user can remove the card stacks on the support plate 52.

[0053] A card-pushing device 40 is provided on the central protrusion of the card storage tray 31. The card-pushing device 40 includes a rotatable card-pushing rotating seat 42, a card-pushing arm 43, and a card-pushing base 41. The card-pushing rotating seat 42 is connected to the card-pushing base 41 through the card-pushing arm 43, so that the card-pushing base 41 can rotate in a circular motion within the card storage slot 311, thereby pushing the mahjong tiles near the card inlet 311A ​​to the vicinity of the card outlet 311B, and finally rising to the tabletop through the support plate 51.

[0054] Figure 5 This is a structural diagram of the card stacking device in an embodiment of the present invention; Figure 6 This is a structural diagram of the card-drawing unit in an embodiment of the present invention; Figure 7 This is an exploded view of the card stacking device in an embodiment of the present invention.

[0055] like Figure 5 , 6 As shown in Figure 7, the stacking device 20 is located at the card supply port of the card supply device 10. It has a stacking unit and a card-dispensing unit. The stacking unit is used to stack the mahjong tiles supplied by the card supply device 10 to form a stack of tiles. The card-dispensing unit is used to dispense the stack of tiles or a mahjong tile into the card inlet 311A ​​of the storage slot 311.

[0056] The stacking unit includes a stacking block 21 for stacking mahjong tiles, which is raised and lowered at the tile supply port. The card-dispensing unit includes a frame, a card-dispensing motor 24 mounted on the frame, a card-dispensing drive wheel 23, a card-dispensing push rod 26, an auxiliary push rod 27, and a card-dispensing block 25.

[0057] In this embodiment, the frame is a card storage tray 31, and the entire card stacking device 20 is fixed at the card inlet 311A ​​of the card storage tray 31. The card-dispensing motor 24 is fixed to the bottom of the card storage tray 31. The card-dispensing drive wheel 23 is mounted on the main shaft of the card-dispensing motor 24 via a bushing; the two are coaxial and horizontally arranged, and are driven to rotate by the card-dispensing motor 24.

[0058] A curved annular groove 232 is formed on the outer circumferential wall of the card-dispensing drive wheel 23. Card-dispensing push rods 26 and auxiliary push rods 27 are arranged horizontally above the card-dispensing drive wheel 23 and distributed along the axial direction of the card-dispensing drive wheel 23. An movable gap is formed between the card-dispensing push rods 26 and auxiliary push rods 27.

[0059] One end of the card-dispensing push rod 26 is hinged to the frame (card storage tray 31) directly in front of the card supply port via a first pivot 262. Its middle section is bent and equipped with a card-dispensing slider 263 that slides within a curved annular groove 232. The card-dispensing slider 263 can be a slider or a roller. The other end of the card-dispensing push rod 26 is connected to the card-dispensing block 25. The auxiliary push rod 27 has a structure basically the same as the card-dispensing push rod 26, except that it lacks the card-dispensing slider 263. Specifically, one end of the auxiliary push rod 27 is hinged to the frame (card storage tray 31) directly in front of the card supply port via a second pivot 272, and its other end is mounted on the card-dispensing block 25.

[0060] Specifically, the other end of the card-pulling push rod 26 is vertically provided with a connecting post 261, and the card-pulling block 25 has a mounting hole 251 that matches the connecting post 261. The connecting post 261 rotates within the mounting hole 251. The other end of the auxiliary push rod 27 is vertically provided with a connecting post 271, and the card-pulling block 25 has a mounting hole 252 that matches the connecting post 271. The connecting post 271 rotates within the mounting hole 252. The axes of the connecting post 261, the first rotating shaft 262, the connecting post 271, and the second rotating shaft 272 are all vertically arranged and are separately installed from the corresponding card-pulling push rod 26 or auxiliary push rod 27.

[0061] In another embodiment, both connecting post 1 261 and connecting post 271 are hollow and have open upper ends with elastic buckles, so that connecting post 1 3b and connecting post 2 7b can be more smoothly engaged in the corresponding mounting holes 1 251 and 2 252.

[0062] In another embodiment, the push rod 26, the connecting post 261, and the first rotating shaft 262 are integral structures, and preferably all three are injection molded as one piece; the auxiliary push rod 27, the connecting post 271, and the second rotating shaft 272 are integral structures, and preferably all three are injection molded as one piece.

[0063] In addition, such as Figure 3 As shown, in order to prevent impurities from entering the card-dispensing drive wheel 23, a cover plate 28 is also provided above the card-dispensing drive wheel 23. The cover plate 28 is fixed on the frame (card storage tray 31). The cover plate 28 can also facilitate the installation, debugging and maintenance of the card-dispensing drive wheel 23, the card-dispensing push rod 26 and the auxiliary push rod 27.

[0064] The card-dispensing block 25 has a vertical card-dispensing surface 253. The side of the card-dispensing surface 253 near the card-feeding opening is provided with an inclined surface to facilitate the entry of mahjong tiles into the stacking block 21. When the card-dispensing motor 24 rotates, the card-dispensing push rod 26 can swing horizontally with the rotation of the card-dispensing drive wheel 23, thereby causing the card-dispensing surface 253 of the card-dispensing block 25 to swing back and forth in a vertical posture, and dispensing the mahjong tiles on the stacking block 21 into the card-feeding opening 311A ​​of the card storage slot 311.

[0065] During the swinging process, the card-pushing surface 253 of the card-pushing block 25 will not tilt upward or downward, which can prevent the mahjong tiles from flipping over or failing to stack due to the upward tilt of the card-pushing surface 253 when supplying tiles.

[0066] In another embodiment, the card-pulling block 25 can be directly fixed to the movable end of the card-pulling push rod 26, eliminating the need for the auxiliary push rod 27. This also prevents the mahjong tiles from flipping over or failing to stack.

[0067] In this embodiment, the auxiliary push rod 27 can increase the stability of the card-pulling push rod 26 driving the card-pulling block 25 to swing; on the other hand, it can also control the left and right offset angle of the card-pulling surface 253 when swinging, so that the vertical card-pulling surface 253 can send the mahjong tiles into the card storage device as far as possible along the arc direction of the card storage slot.

[0068] In addition, sound insulation layers are provided on the top surface of the card-dispensing surface 253, the stacking block 21, and the side wall of the frame (card storage tray 31) directly opposite the card-supplying port to reduce the sound of mahjong tiles colliding.

[0069] Figure 8 This is a structural diagram of the curved annular groove on the card-dispensing drive wheel in an embodiment of the present invention.

[0070] like Figure 8 As shown, the curved annular groove 232 has a starting groove 232A, a card-pulling groove 232B, and a reset groove 232C.

[0071] When the sliding member 263 of the card-dispensing push rod 26 moves to the starting groove 232A, the movable end of the card-dispensing push rod 26 and the card-dispensing block 25 are both kept in the initial position on the side of the stacked card block 21 away from the card inlet 311A. When the sliding member 263 of the card-dispensing push rod 26 moves to the card-dispensing groove 232B, the movable end of the card-dispensing push rod 26 and the card-dispensing block 25 move towards the card inlet 311A ​​of the storage groove (i.e., the card-dispensing direction) to dispense the mahjong tiles of the stacked card block 21 into the card inlet 311A. When the sliding member 263 of the card-dispensing push rod 26 moves to the reset groove 232C, the movable end of the card-dispensing push rod 26 and the card-dispensing block 25 reset to the initial position.

[0072] Figure 9 This is an exploded view of the card-dispensing drive wheel in an embodiment of the present invention.

[0073] like Figure 9 As shown, the card-pulling drive wheel includes a first drive wheel 233, a second drive wheel 234, and a fixing component.

[0074] The first drive wheel 233 has a first groove wall 2331 formed on the outer periphery of its end face; the second drive wheel 234 has a second groove wall 2341 formed on the outer periphery of its end face that matches the first groove wall 2331; the fastener is preferably a screw, used to fix the first drive wheel 233 and the second drive wheel 234, and to form a curved annular groove 232 between the first groove wall 2331 and the second groove wall 2341, which facilitates the processing and forming of the drive wheel and reduces production costs. The material can be plastic or metal.

[0075] To facilitate positioning and fixing, at least one positioning post and at least one positioning groove matching the positioning post are respectively provided on the corresponding end faces of the first drive wheel 233 and the second drive wheel 234. The positioning post includes an axial positioning post and a circumferential positioning post, and the positioning groove includes a corresponding axial positioning groove and a circumferential positioning groove.

[0076] In this embodiment, an axial positioning post 2332 is provided at the center of the end face of the first drive wheel 233, and two circumferential positioning posts 2333 are provided around the axial positioning post 2332. An axial positioning groove 2342 adapted to the axial positioning post 2332 and a circumferential positioning groove 2343 corresponding to the circumferential positioning post 2333 are provided at the center of the corresponding end face of the second drive wheel 234. A threaded hole is provided in the circumferential positioning groove 2343, and a through hole is provided in the circumferential positioning post 2333. The fixing member passes through the through hole and is fixed in the threaded hole, thereby realizing the fixed installation of the first drive wheel 233 and the second drive wheel 234.

[0077] Figure 10 This is a structural diagram of the axial end face of the second drive wheel in an embodiment of the present invention.

[0078] like Figure 10 As shown, on the axial projection plane of the card-pulling drive wheel, i.e., through the side view of the second drive wheel 234, it can be seen that the arc angle α corresponding to the card-pulling groove 232B is greater than the arc angle β corresponding to the reset groove. The arc angle α is 1.5-3 times the arc angle β, preferably 2 times. For example, the arc angle α = 160 degrees and the arc angle β = 80 degrees. This allows the card-pulling block 25 to have a card-pulling time much longer than the reset time, achieving the effect of slow card-pulling and fast reset, thereby reducing the noise of card-pulling, saving the reset time when not pulling cards, and improving the efficiency of the entire card-pulling action.

[0079] Figure 11 This is another structural view of the stacking device in an embodiment of the present invention.

[0080] like Figure 11As shown, in this embodiment, the card stacking unit and the card dispensing unit share the card dispensing motor 24 and the card dispensing drive wheel 23. The end face of the card dispensing drive wheel (i.e., the outer end face of the second drive wheel 234) is provided with a card stacking trajectory groove 231. The card stacking unit also includes a card stacking drive rod 22, a card stacking guide seat 212, and a card stacking rotating seat 222.

[0081] One end of the card stacking drive rod 22 is provided with a card stacking rotation shaft 221. A card stacking rotation seat 222 adapted to the card stacking rotation shaft 221 is provided on the frame (card storage tray 31). The card stacking drive rod 22 is rotatably mounted on the card stacking rotation seat 222. A slider 223 is also provided in the middle of the card stacking drive rod 22, which is slidably fitted into the card stacking trajectory groove 231. The other end of the card stacking drive rod 22 is provided with a sliding post 224. A card stacking block groove 211 with one end open and adapted to the sliding post 224 is opened on the back of the card stacking block 211. The card stacking block groove 211 is horizontally arranged. When the card pushing drive wheel 23 rotates, the card stacking drive rod 22 swings up and down, thereby driving the card stacking block 21 to move up and down.

[0082] To increase the stability of the stacking block 21 moving up and down, a stacking guide seat 212 is fixedly installed at the corresponding position of the frame (storage tray 31). The stacking guide seat 212 has a vertically arranged guide groove or guide rod 213 for guiding the stacking block 21 up and down. The stacking block 2 has a guide part, which is movably set on the guide groove or guide rod 213 to achieve lifting and lowering.

[0083] Figure 12 This is a structural diagram of the card stacking trajectory groove on the card-dispensing drive wheel in an embodiment of the present invention.

[0084] like Figure 12 As shown, the stacking track groove 231 is approximately annular, with a concave section 231A and a convex section 231B. When the slider in the middle of the stacking drive rod 22 moves to the convex section 231B, the stacking block 21 is at its highest position, with its top plane slightly lower than the upper end plane of the belt assembly. The height difference is slightly less than the thickness of a mahjong tile, allowing the first mahjong tile conveyed by the belt assembly to slide smoothly onto the top plane of the stacking block 21. When the slider 223 in the middle of the stacking drive rod 22 is in the concave section 231A, the stacking block 21 is at its lowest position, with its top plane lower than the upper end plane of the belt assembly. The height difference is slightly greater than the thickness of a mahjong tile, allowing the second mahjong tile conveyed by the supply belt 15 to be stacked on top of the stacking block 21 and placed on top of the first mahjong tile, thus forming a tile pile.

[0085] like Figure 3As shown, a counting sensor 29 is installed on the frame (storage tray 31) on one side of the stacking block 21. The counting sensor 29 is a magnetic induction sensor, which can generate an induction signal when a mahjong tile with an embedded magnet passes through, thereby counting the mahjong tiles that enter the stacking block 21 and the storage tray.

[0086] like Figure 7 As shown, a card-dispensing sensing point 291, a high-position card-stacking sensing point 293, and a low-position card-stacking sensing point 294 are provided on the other end face of the card-dispensing drive wheel 23 (i.e., the outer end face of the first drive wheel 233). All three are magnets. The high-position card-stacking sensing points 293 and 294 are distributed on the same radius, while the card-dispensing sensing point 291 is distributed on a more outer radius. Corresponding positions on the frame (card storage tray 31) are provided with a card-dispensing sensor 292 corresponding to the card-dispensing sensing point 291 and a card-stacking sensor 295 corresponding to the high-position card-stacking sensing point 293 and the low-position card-stacking sensing point 294, respectively, to generate working signals to control the card-dispensing motor to stop.

[0087] Figure 13 This is a schematic diagram of the trajectories of the stacked and drawn card blocks in an embodiment of the present invention.

[0088] like Figure 13 As shown, the horizontal axis represents the rotation angle of the card-pulling motor 24 or the card-pulling drive wheel 23, and the vertical axis represents the moving distance of the stacking and card-pulling blocks. The solid line represents the trajectory of the card-pulling block, and the dashed line represents the trajectory of the stacking block 21. This embodiment uses a 360° rotation of the card-pulling drive wheel 23 as an example. Figure 13 A / B / C / D in the diagram represent the corresponding angular positions.

[0089] When the card-dispensing drive wheel 23 is at 0°, the card-stacking block 21 is at its highest position, and the card-dispensing block 25 is at its starting position. At this time, the high-position card-stacking sensing point 293 is opposite the card-stacking sensor 295, and the card-stacking sensor 295 controls the card-dispensing motor 24 to stop (i.e., it is in a stopped state). Figure 5 Location.

[0090] When the first mahjong tile enters the stacking block 21, the counting sensor 29 counts and controls the tile-pulling motor 24 and the tile-pulling drive wheel 23 to rotate until the stacking low position sensing point 294 rotates to the opposite side of the stacking sensor 295. The stacking sensor 295 controls the tile-pulling motor 24 to stop (i.e., rotate to position A). At this time, the stacking block 21 is at its lowest position, and the tile-pulling block 25 is still at its starting position.

[0091] When the second mahjong tile enters the stacking block 21, the counting sensor 29 counts and controls the tile-pulling motor 24 and the tile-pulling drive wheel 23 to rotate. First, it drives the stacking block 21 to move to the highest position and rotates to angle B. Then, it drives the tile-pulling block 25 to move in the tile-pulling direction and pushes the tile stack formed by the two mahjong tiles into the tile storage slot (i.e., rotates to angle D). Finally, it resets until the stacking high position sensing point 293 moves to the opposite side of the stacking sensor 295. The stacking sensor 295 controls the tile-pulling motor 24 to stop, thus completing the stacking and tile-pulling of a set of tile stacks. The next set of tile stacks is then cycled in sequence.

[0092] When the counting sensor 29 detects that the mahjong tiles in the storage slot have reached the specified number, the tile-pulling block 25 will reset to the starting position and continue to move until the tile-pulling sensing point 291 moves to the opposite side of the tile-pulling sensor 292. The tile-pulling sensor 292 controls the tile-pulling motor 24 to stop. At this time, the tile-pulling motor 24 rotates to position C, and the tile-pulling block 25 moves to the center position of the stacking block 21, which can block the tile supply port and prevent the mahjong tiles in the tile supply device 10 from continuing to come out.

[0093] The role and effect of the embodiments

[0094] According to the card pushing device, card feeding mechanism, and mahjong machine provided in this embodiment, since the arc angle α corresponding to the card pushing groove 232B on the axial projection surface of the card pushing drive wheel is greater than the arc angle β corresponding to the reset groove, and the arc angle α is 1.5-3 times the arc angle β, the card pushing block 25 can achieve a card pushing time that is much longer than the reset time, thus achieving the effect of slow card pushing and fast reset. This reduces the noise of card pushing and saves the reset time when not pushing cards, thereby improving the efficiency of the entire card pushing action.

[0095] Based on this, in this embodiment, the card-dispensing drive wheel includes a first drive wheel 233, a second drive wheel 234, and a fixing member. The outer periphery of the end face of the first drive wheel 233 is formed with a first groove wall 2331; the outer periphery of the end face of the second drive wheel 234 is formed with a second groove wall 2341 that matches the first groove wall 2331; the fixing member fixes the first drive wheel 233 and the second drive wheel 234, and forms a curved annular groove 232 between the first groove wall 2331 and the second groove wall 2341, facilitating the processing and forming of the card-dispensing drive wheel and reducing production costs.

[0096] In this embodiment, the card-dispensing block 25 has a vertical card-dispensing surface 253. When the card-dispensing motor 24 rotates, the card-dispensing push rod 26 can swing horizontally along with the card-dispensing drive wheel 23, thereby causing the card-dispensing surface 253 of the card-dispensing block 25 to reciprocate and swing vertically, dispensing the mahjong tiles on the stacking block 21 into the inlet 311A ​​of the storage slot 311. In this way, during the swinging process, the card-dispensing surface 253 of the card-dispensing block 25 will not tilt upward or downward, which can prevent the mahjong tiles from tipping over or failing to stack due to the upward tilt of the card-dispensing surface 253, making the stacking smoother.

[0097] Meanwhile, above the card-dispensing drive wheel 23, card-dispensing push rods 26 and auxiliary push rods 27 are arranged horizontally in sequence and distributed along the axial direction of the card-dispensing drive wheel 23. In this embodiment, the auxiliary push rod 27 can increase the stability of the card-dispensing push rod 26 driving the card-dispensing block 25 to swing; on the other hand, it can also control the left and right offset angle of the card-dispensing surface 253 when swinging, so that the vertical card-dispensing surface 253 can feed the mahjong tiles into the card storage device as much as possible along the arc direction of the card storage slot.

[0098] Furthermore, a stacking guide seat 212 is fixedly installed on the frame (card storage tray 31). The stacking guide seat 212 has a vertically arranged guide groove or guide rod 213 for guiding the stacking blocks 21 up and down. The stacking blocks 2 have a guide part, which is movably arranged on the guide groove or guide rod 213 to achieve lifting and lowering, thereby increasing the stability of the stacking blocks 21 moving up and down.

[0099] In addition, when the counting sensor 29 detects that the mahjong tiles in the storage slot have reached the specified number, the tile-pulling block 25 will continue to move after resetting to the starting position until the tile-pulling sensing point 291 moves to the opposite side of the tile-pulling sensor 292. The tile-pulling sensor 292 controls the tile-pulling motor 24 to stop. At this time, the tile-pulling motor 24 rotates to position C, and the tile-pulling block 25 moves to the center position of the stacking block 21, which can block the tile supply port and prevent the mahjong tiles in the tile supply device 10 from continuing to come out.
