[0004] To achieve the above objectives, the present invention provides an automatic mahjong machine with inclined rail card feeding, comprising a machine base plate, a machine cover, a tabletop, a large tray, a card flipping magnet, a first drive device, a control motherboard, four sets of card feeding components and four sets of card lifting components, wherein the machine cover is fixedly mounted on the machine base plate, and the tabletop is located on the top surface of the machine cover with four card lifting openings constructed between the two. The large plate is set on the machine base plate and includes an edge area and an inner area located inside the edge area. There is at least one flipping magnet and it is correspondingly set below the inner area of ​​the large plate. The flipping magnet is used to flip the mahjong tiles to a face-down state by the reaction force of the magnetic force. The first driving device is used to drive the large plate to rotate. The large plate is constructed to be suitable for the mahjong tiles on it to slide towards the edge area during its rotation. The edge area of ​​the large plate is evenly spaced around the circumference with a number of square holes with shapes adapted to the mahjong tiles and is divided into four arc-shaped areas. Each set of the card-feeding components includes a large disc track, a card-receiving opening, a card-feeding track, and a horizontal push rod. The large disc track and the card-feeding track are respectively located on both sides of the card-receiving opening.

[0010] The design further includes a track magnet on the large track component for drawing mahjong tiles with the face down into the square hole.

[0011] The further configuration includes: the card-feeding component also includes a card-arranging bracket fixedly connected to the machine cover, the card-arranging bracket being positioned above the arc-shaped area of ​​the large plate and partially blocking the square holes, the card-receiving port being located below the card-arranging bracket, and the card-arranging bracket having a baffle on its inner side for guiding the sliding mahjong tiles toward the square holes on the side away from the card-receiving port.

[0012] Further configured as follows: the second end of the lifting plate, corresponding to the end furthest from the plate-raising track, is hinged to the plate-arranging bracket and its second end is connected to the tabletop; the first end of the lifting plate is connected to the plate-arranging bracket via a rotating connecting rod; the rotating connecting rod includes a first connecting member and a second connecting member that are hinged together; the upper end of the first connecting member is hinged to the first end of the lifting plate; and the lower end of the second connecting member is hinged to the plate-arranging bracket. The third driving device includes a small cylinder disposed between the card holder and the card lifting plate. The piston rod at the front end of the small cylinder is connected to the hinge of the rotating connecting rod to drive the rotating connecting rod to rotate around the hinge for engagement or disengagement. The rear end of the small cylinder is hinged to the card holder.

[0013] The further configuration includes a power module for providing power to the small cylinders of the four sets of lifting components. The power module includes a large cylinder and a lifting motor. A rack is provided on the piston rod of the large cylinder, and the lifting motor is connected to the rack of the large cylinder through a gear on its output shaft. The large cylinder is also provided with four outlets, and the four outlets are respectively connected to four small cylinders through transmission pipes.

[0014] A further configuration is provided: a first sensing element is provided on the rack of the large cylinder; It also includes at least two first control elements disposed on the movement path of the rack and used to generate signals by interacting with the first sensing element on the rack, wherein at least two first control elements are connected to the control motherboard signal.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. The traditional mahjong machine's card-collecting wheel structure has been eliminated. By using square holes along the edge of the large plate, combined with a beveled design, magnetic card flipping, and adsorption structure, the mahjong tiles are accurately inserted into the holes and arranged. With the card arrangement bracket and track magnet correction structure, the consistency of the tile orientation is ensured. The card arrangement structure is simple and the effect is accurate. 2. The use of motor-coordinated drive instead of traditional multi-motor distributed drive reduces the number of motors and control components to nearly one-third of that of traditional mahjong machines, greatly simplifying the overall structure of the equipment, reducing failure points, improving the stability of equipment operation, and reducing production and manufacturing costs as well as subsequent maintenance costs. 3. The tile-pushing structure adopts a sloping rail for tile feeding. The tile feeding slide of the tile feeding track component and the guide slide formed by the structure limit the movement trajectory of the horizontal push rod. With the help of the telescopic horizontal push rod and wear-resistant bushing, the balance and flexibility of the pushing force are ensured, so as to realize the smooth and accurate pushing of mahjong tiles along the sloping rail and avoid the tiles from tilting or deviating. 4. The tile-lifting assembly, which links a large cylinder with four smaller cylinders, is driven by a tile-lifting motor to achieve synchronous lifting and lowering of the four tile-lifting plates. With the precise positioning of sensing and control elements, the tile-lifting plates are precisely aligned with the tile-raising track, and the tile-lifting action is precisely started and stopped. At the same time, the tile-pushing and tile-lifting actions are linked in a closed loop through the control motherboard, which improves the coordination and automation of the overall mahjong machine. 5. The receiving port is set to receive two mahjong tiles at a time. By using the design that the stacked height of the two tiles is level with the bottom of the large plate, the resistance when the large plate rotates is avoided from the source, ensuring the smooth rotation of the large plate and improving the efficiency of shuffling and arranging the tiles.

[0022] The following detailed description of a specific embodiment of the present invention is provided in conjunction with the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0023] This invention relates to an automatic mahjong machine with a slanted track for loading tiles, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a machine base plate 10, a machine cover 20, a desktop 30, a large tray 40, a flipping magnet 45, a first drive device, a control motherboard 60, an operation panel lifting bracket 50, four sets of card-adding components 70, and four sets of card-lifting components 80.

[0024] In this embodiment, as Figure 3 , Figure 4 and Figure 5As shown, the machine casing 20 is fixedly mounted on the machine base plate 10 to form a mounting cavity between the two; wherein, the operating panel lifting bracket 50 is fixedly mounted on the machine base plate 10 and is a cylindrical structure, the large plate 40 is rotatably mounted on the machine base plate 10 and has a through hole 421 in its middle for the operating panel lifting bracket 50 to pass through, and the operating panel lifting bracket 50 is provided above the large plate 40 with several scraping strips 51 for guiding (pushing) the mahjong tiles 90 on the large plate 40 to the edge during the rotation of the large plate 40; the large plate 40 includes an edge region 41 located at the edge and an inner region 42 located inside the edge region 41, and at least one flipping magnet 45 is provided and is correspondingly located below the inner region 42 of the large plate 40. The flipping magnet 45 is used to flip the tiles by using the reaction force of the magnetic force to... The mahjong tiles 90 (with built-in magnets) on the large plate 40 are flipped to face down. The first driving device is used to drive the large plate 40 to rotate and is connected to the control main board 60. Specifically, the first driving device is preferably a large plate motor 44. The large plate 40 is provided with a large plate gear ring 43 on its lower surface. The large plate motor 44 is located below the large plate 40 and drives the large plate 40 to rotate by meshing the gear on its output shaft with the large plate gear ring 43. At the same time, the large plate 40 is constructed to be suitable for the mahjong tiles 90 on it to slide to the edge area 41 during its rotation. Specifically, the inner area 42 of the large plate 40 is a truncated cone structure that rises upward. In this way, during the rotation of the large plate 40, the mahjong tiles 90 on the inner area 42 can easily slide down the cone surface (sloping surface) to the edge area 41.

[0025] In this embodiment, as Figure 4 and Figure 5 As shown, the edge region 41 of the large plate 40 is evenly spaced with a number of square holes 411 whose shapes are adapted to the mahjong tiles 90. The edge region 41 of the large plate 40 is divided into four arc-shaped regions, and each arc-shaped region has the same number of complete square holes 411. Each set of tile-feeding components 70 includes a large plate track component 71, a tile-receiving port component 72, a tile-feeding track component 73, and a horizontal push rod 74. The tile-receiving port component 72 and the large plate track component 71 of the same set are all located below the same arc-shaped region of the large plate 40. The four sets of tile-receiving port components 72 and large plate track components 71 are evenly arranged below the edge region 41 of the large plate 40 to divide the edge region 41 into four arc-shaped regions. The arc-shaped regions are the edge regions 41 corresponding to the same set of large plate track components 71 and tile-receiving port components 72, and they change in real time during the rotation of the large plate 40. The arc-shaped regions mentioned below are all relative to the large plate 40 when it is stationary. Figure 5 The area between adjacent dotted lines is the arc-shaped area.

[0026] In the above scheme, the receiving slot 72 is located below the outermost square hole 411 of the arc-shaped area to receive the mahjong tiles 90 falling from the square hole 411. The large plate track 71 is located below the remaining square holes 411 in the arc-shaped area to cooperate with the upper square hole 411 to form a receiving groove for accommodating the mahjong tiles 90. At the same time, the gap between the large plate track 71 and the receiving slot 72 is constructed so that the mahjong tiles 90 falling into the square hole 411 can pass over it as the large plate 40 rotates. Thus, the mahjong tiles falling into the square hole 411... The tile 90 can rotate with the large plate 40 until it falls into the receiving slot 72. Preferably, the receiving slot 72 is configured to receive two mahjong tiles 90 at a time, with the height of the two mahjong tiles 90 stacked being level with the bottom surface of the large plate 40. In this way, the mahjong tiles 90 falling into the receiving slot 72 will not create resistance to the rotation of the large plate 40, ensuring the smooth rotation of the large plate 40. At the same time, it ensures that the mahjong tiles 90 falling into the square hole 411 can rotate normally synchronously with the large plate 40 without falling into the receiving slot 72.

[0027] In the above scheme, in order to facilitate the mahjong tiles 90 on the large plate 40 falling into the square hole 411, the square hole 411 is preferably a conical hole structure with a larger top and a smaller bottom; at the same time, in order to ensure that the mahjong tiles 90 fall into the square hole 411 better and more accurately and ensure that the mahjong tiles 90 are facing the correct direction, the large plate track component 71 is preferably provided with a track magnet for sucking the mahjong tiles 90 with the face down into the square hole 411. In this way, the attraction force of the track magnet can easily suck the mahjong tiles 90 with the correct direction in the edge area 41 into the square hole 411.

[0028] In this embodiment, as Figure 4 and Figure 5As shown, the receiving slot 72 has openings through both sides. The card-laying track 73 and the large-plate track 71, belonging to the same group, are respectively positioned on either side of the opening of the receiving slot 72. The card-laying track 73 has an upwardly extending card-laying slide, the lower end of which connects to the opening of the receiving slot 72. A horizontal push rod 74 is positioned between the large-plate track 71 and the receiving slot 72 to push the mahjong tiles 90 inside the receiving slot 72 into the card-laying slide of the card-laying track 73 via a second driving device. This second driving device is signal-connected to the control motherboard 60. In this embodiment, the card-laying track 73 is positioned outside the adjacent group of card-laying track 73. Specifically, the second driving device includes a pusher tooth ring. The pusher ring 75 and the pusher motor 77 are rotatably mounted on the machine base plate 10 outside the plate mounting track 73. The pusher motor 77 is connected to the pusher ring 75 through a gear on its output shaft. Four vertical push rods 76 are fixedly connected to the pusher ring 75, and each vertical push rod 76 is provided with a vertical sliding opening 761. The ends of four horizontal push rods 74 are movably mounted in the vertical sliding openings 761 of the four vertical push rods 76. Thus, the pusher ring 75 can rotate when the pusher motor 77 works, thereby linking the vertical push rods 76 and the horizontal push rods 74 to move. At the same time, the horizontal push rods 74 can slide along the vertical sliding openings 761 at their ends to adjust their constantly changing positions.

[0029] In the above scheme, such as Figure 5 As shown, to ensure the reliability and stability of the horizontal push rod 74 pushing the mahjong tile 90, it is preferable that the tile-loading track component 73 is provided with a guide slot 731 on the outer wall of the tile-loading slide, or the outer wall of the tile-loading track component 73 and the component above (which can be an independent component fixedly connected to the machine cover 20 or a part of the machine cover 20) cooperate to form a guide slot 731. The guide slot 731 is used for the horizontal push rod 74 to pass through and extend into the tile-loading slide, and at the same time, it is used to constrain and guide the horizontal push rod 74 to slide. The guide trajectory of the guide slot 731 is consistent with the guide trajectory of the tile-loading slide. More preferably, the horizontal push rod 74 is a telescopic rod structure and is fitted with a wear-resistant bushing 741 that cooperates with the guide slot 731. In this way, the horizontal push rod 74 can better adapt to the movement and adjust, and at the same time, the wear-resistant bushing 741 can control the balance and flexibility of the tile-pushing force to ensure the smoothness of the tile-pushing action.

[0030] In the above scheme, in order to ensure the reliability of the rotation of the pusher tooth ring 75, it is preferable that the teeth of the pusher tooth ring 75 are set along its outer edge, and at least three positioning gears 79 are rotatably set on the machine base plate 10, which mesh with the teeth of the pusher tooth ring 75. The position and rotation trajectory of the pusher tooth ring 75 are limited by the cooperation of at least three positioning gears 79, thus ensuring the reliability and stability of the rotation of the pusher tooth ring 75.

[0031] In this embodiment, the receiving slot 72 is equipped with a counting control element for counting the number of tiles that fall into it. This counting control element is connected to the control main board 60. Preferably, the counting control element is positioned at a height greater than the thickness of a single mahjong tile 90 but less than the thickness of two mahjong tiles 90. Thus, when all four receiving slots 72 have received two mahjong tiles 90, the counting control element sends a signal to the control main board 60 to control the pusher motor 77 to operate, causing the horizontal pusher 74 to push the two stacked (attracted) mahjong tiles 90 in the receiving slots 72 to the top. The mahjong tiles 90 pushed into the tile track 73 are positioned at a predetermined location. Then, the control board 60 controls the tile pusher motor 77 to reverse so that the horizontal pusher 74 is reset in preparation for the next tile pusher operation. Since the pushing distance is short, the control board 60 can control the tile pusher by controlling the working time or the number of rotations of the tile pusher motor 77, or it can be controlled by a sensor. To prevent the mahjong tiles 90 pushed into the tile track 73 from sliding down the tile slide, the slope of the tile slide of the tile track 73 is 5°-10°. By controlling the slope of the tile slide, the stacked mahjong tiles 90 are prevented from sliding down.

[0032] In this embodiment, each set of tile-loading components 70 also includes a tile-arranging bracket 78 fixedly connected to the machine housing 20. The tile-arranging bracket 78 is positioned above the arc-shaped area of ​​the large tray 40 and partially blocks the square holes 411. The tile-receiving port 72 is located below the tile-arranging bracket 78, meaning that some of the square holes 411 in the arc-shaped area that mate with the large tray track component 71 are located outside the tile-arranging bracket 78. At the same time, the tile-arranging bracket 78 has a baffle 781 on its inner side to guide the sliding mahjong tiles 90 toward the square holes 411 on the side away from the tile-receiving port 72. Thus, the baffle 781 helps the mahjong tiles 90 fall into the square holes 411 more effectively. Preferably, the distance between the lower end face of the tile-arranging bracket 78 and the upper surface of the large tray 40 is less than that of a single mahjong tile. The thickness of the mahjong tile 90 is such that the distance between the lower end of the tile-arranging bracket 78 and the upper end of the large plate track 71 is greater than the thickness of a single mahjong tile 90. This structure allows only the mahjong tiles 90 that are placed in the square holes 411 to pass through the tile-arranging bracket 78 as the large plate 40 rotates. The mahjong tiles 90 that do not enter the square holes 411 will be pushed away by the tile-arranging bracket 78, making it easier for the mahjong tiles 90 to enter the square holes 411 of the large plate 40. Furthermore, the large plate track 71 is provided with track magnets at least on the part corresponding to the part outside the tile-arranging bracket 78. In this way, the track magnets will throw out the mahjong tiles 90 that have not been flipped to the face-down position through repulsive force, and push them away with the tile-arranging bracket 78, further ensuring that the mahjong tiles 90 that fall into the tile receiving slot 72 are in the face-down position.

[0033] In this embodiment, as Figure 2 , Figure 4 and Figure 6As shown, the desktop 30 is fixedly installed above the machine casing 20, and four tile-lifting openings 31 are formed between the two. The four sets of tile-lifting components 80 are respectively matched with the four sets of tile-feeding components 70 to receive the mahjong tiles 90 pushed by the tile-feeding components 70 and transfer the mahjong tiles 90 from the tile-lifting openings 31 to the desktop 30. Each set of tile-lifting components 80 includes a tile-lifting plate 81 and a third drive device connected to the control main board 60. The third drive device is connected to the tile-lifting plate 81 to drive the tile-lifting plate 81 to switch between a first state and a second state. In the first state, the tile-lifting plate 81 blocks the tile-lifting openings 31 and is flush with the desktop 30. In the second state, the first end of the tile-lifting plate 81, which is close to the tile-feeding track component 73, is connected to the upper port of the tile-feeding slide so that the horizontal push rod 74 can push the mahjong tiles 90 onto the tile-lifting plate 81.

[0034] In this embodiment, as Figure 2 , Figure 4 and Figure 6 As shown, four tile-arranging supports 78 extend from the four tile-raising openings 31 on the tabletop 30, respectively. A tile-raising plate 81, with its second end hinged to the tile-arranging support 78 and connected to the tabletop 30, allows the mahjong tiles 90 to slide onto the tabletop 30 along the tile-raising plate 81 in its second state, pushed by a horizontal push rod 74. The first end of the tile-raising plate 81 is connected to the tile-arranging support 78 via a rotating connecting rod 83, which includes a first connecting member 831 and a second connecting member 832 hinged together. The upper end of the first connecting member 831 is hinged to the first end of the tile-raising plate 81, and the lower end of the second connecting member 832 is hinged to the tile-arranging support 78. A third driving device is provided between the tile-arranging support 78 and the tile-raising plate 81. A small cylinder 82 is located between 1 and 2. The piston rod at the front end of the small cylinder 82 is connected to the hinge of the rotating connecting rod 83 to drive the rotating connecting rod 83 to rotate around the hinge for engagement or disengagement. The rear end of the small cylinder 82 is hinged to the card holder 78. Preferably, the hole for engaging the hinge shaft at the lower end of the card holder 78 and the second connecting member 832 is a strip-shaped hole to accommodate the positional changes of the rotating connecting rod 83 during its operation. Specifically, when the piston rod of the small cylinder 82 extends and pushes the rotating connecting rod 83 to open, the first end of the card lifting plate 81 gradually rises until it is in the first state and flush with the tabletop 30. When the piston rod of the small cylinder 82 retracts and pulls the rotating connecting rod 83 to engage, the first end of the card lifting plate gradually lowers until it is in the second state and connected to the upper port of the card mounting track 73.

[0035] In this embodiment, as Figure 6As shown, the extension and retraction of the small cylinders 82 of the four sets of lifting components 80 are all driven by the same power module. This power module includes a large cylinder 84 fixedly mounted on the machine base plate 10 and a lifting motor 85. A rack 841 is provided on the piston rod of the large cylinder 84. The lifting motor 85 drives the piston rod of the large cylinder 84 to extend or retract through a gear meshing with the rack 841 at its output end. The large cylinder 84 has four outlets, each connected to one of the four small cylinders 82 via a transmission pipe. This transmits the power from the lifting motor 85 driving the piston rod of the large cylinder 84 to the piston rods of the four small cylinders 82. This achieves the effect of driving four sets of lifting components 80 with a single lifting motor 85, thereby reducing the number of motors and control components. Preferably, a first sensing element is provided on the rack 841 of the large cylinder 84, and at least two sensing elements are provided along the movement path of the rack 841 to interact with the first sensing element. The first control element 862 generates a signal according to the action of the component. At least two first control elements 862 are connected to the control main board 60. Preferably, there are two first control elements 862, and the positions of the two first control elements 862 correspond to the lifting plate 81 when it is in the first state and the second state, respectively. In this embodiment, specifically, the power module also includes a balance bracket 86 fixedly installed on the machine base plate 10. The rack 841 on the large cylinder 84 has a structure with teeth on both the upper and lower ends. The gear of the lifting motor 85 meshes with the teeth on one end face of the rack 841. The balance bracket 86 is also rotatably provided with a limiting gear 861 that meshes with the teeth on the other end face of the rack 841. In this way, the cooperation between the gear of the lifting motor 85 and the limiting gear 861 can ensure the reliability and stability of the extension or retraction movement of the rack 841. At the same time, the balance bracket 86 can also be adapted to the corresponding installation of at least two first control elements 862.

[0036] In this embodiment, as the large disk 40 (large disk motor 44) and the card pusher motor 77 continuously operate, when the number of cards pushed reaches the set requirement (based on the counting data fed back by the counting control element or the count received from the counting control element), the control motherboard 60 controls the large disk motor 44 and the card pusher motor 77 to stop operating. Simultaneously, it controls the card lifting motor 85 to operate, lowering the first end of the card lifting plate 81 from the first state to the second state, where it just connects with the upper port of the card loading track 73. At this time, the first control element 862 on the balance bracket 86 sends a signal to the control motherboard 60, which receives the signal and... Immediately control the tile-lifting motor 85 to stop working and control the tile-pushing motor 77 to work, so that the tile-pushing gear ring 75 rotates to drive the horizontal push rod 74 to push a predetermined number of mahjong tiles 90 to the predetermined positions of the tile-lifting plate 81 and the table 30. Then, the main board controls the tile-pushing motor 77 to stop working and simultaneously controls the tile-lifting motor 85 to rotate in the opposite direction, so that the tile-lifting plate 81 resets to the first state. At this time, another first control element 862 sends a signal to the control main board 60, and the control main board 60 controls the tile-lifting motor 85 to stop working and simultaneously controls the tile-pushing motor 77 to reverse so that the tile-pushing gear ring 75 resets to the initial position and then stops working.

[0037] In the above scheme, a second sensing element is preferably provided on the lower surface of the pusher tooth ring 75, and at least two second control elements are correspondingly provided on the machine base plate 10 for interacting with the second sensing element and generating signals. At least two second control elements are connected to the control main board 60 by signals. Preferably, the distance from one second control element to the adjacent second control element on the pusher tooth ring is the distance from which the horizontal push rod 74 pushes the mahjong tile 90 to the predetermined position of the tile lifting plate 81 and the table 30. That is, the two adjacent second control elements represent the initial position and the end position of the pusher tooth ring 75, respectively.

[0038] Compared with existing technologies, this invention eliminates the traditional card-collecting wheel structure. By using a motor-driven magnetic card arrangement, inclined rail card loading, and cylinder-linked card lifting structure, the number of motors and control components is greatly reduced, making the overall structure of the mahjong machine simpler and significantly improving operational stability. At the same time, it effectively reduces production and manufacturing costs as well as subsequent maintenance costs. Furthermore, each action is precisely linked through sensing and control components, ensuring the accuracy of card arrangement, pushing, and lifting, thus enhancing the user experience.

[0039] The above-disclosed embodiments are merely examples of the present invention. However, the present invention is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
