DETAILED DESCRIPTION

[0031] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings. It should be understood that the specific implementation methods described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] Figures 1 to 7 A card storage device of an automatic mahjong machine according to the present invention is schematically shown.

[0033] like Figures 1 to 7 As shown, the card storage device of the automatic mahjong machine of the present invention comprises a card shuffling base plate 1, on which a card storage mechanism 2 and a plurality of supporting mechanisms 3 are arranged. In this embodiment, the number of the supporting mechanisms 3 is four, which are evenly distributed on the periphery of the card storage mechanism 2. The supporting mechanisms 3 are used to support the card storage mechanism 2 so that the card storage mechanism 2 is suspended above the card shuffling base plate 1.

[0034] Wherein, the card storage mechanism 2 comprises at least two annular card storage brackets 21. For example, the number of the card storage brackets 21 can be two or three. In the present embodiment, the number of the card storage brackets 21 is two, separated in the upper and lower parts. The upper and lower card storage brackets 21 are coaxial and arranged parallel to each other, so that the card storage mechanism 2 is annular as a whole. A plurality of card grids 211 are arranged equidistantly along the circumferential direction between the top and the bottom of the card storage bracket 21, and the card grids 211 are square and have openings at both ends, so as to facilitate the entry and exit of mahjong cards. The card grids 211 on the two card storage brackets 21 can be used to place all the cards to be touched. A V-shaped protrusion 212 is arranged circumferentially on the outer side wall of the card storage bracket 21, and the V-shaped protrusion 212 protrudes outward along the outer side wall of the card storage bracket 21.

[0035] The support mechanism 3 includes a support seat 31, on which a support shaft 32 extending upward is arranged. At least two V-shaped support rollers 33 are sleeved on the support shaft 32. The number of the V-shaped support rollers 33 on each support mechanism 3 is the same as the number of the card storage brackets 21. In this embodiment, since the number of the card storage brackets 21 is two, the number of the V-shaped support rollers 33 on each support mechanism 3 is also two. The V-shaped support roller 33 is mounted on the support shaft 32 through a bearing 34, so that the V-shaped support roller 33 rotates around the support shaft 32. A V-shaped groove 331 is provided on the outer side wall of the V-shaped support roller 33, and the V-shaped groove 331 cooperates with the V-shaped protrusion 212, so that the support mechanism 3 supports the card storage bracket 21 and forms a rotation connection with the card storage bracket 21.

[0036] A motor gear assembly is arranged on the shuffling base plate 1, and the motor gear assembly is located on the inner side of the card storage mechanism 2. The motor gear assembly is used to cooperate with the card storage mechanism 2 and drive the card storage mechanism 2. The motor gear assembly includes a driving motor 4 and a gear assembly. A first gear 5 is installed on the output shaft of the driving motor. The gear assembly includes a connecting shaft 6 and a second gear 7, a third gear 8 and a fourth gear 9 sleeved on the connecting shaft 6. Among them, the second gear 7 is located between the third gear 8 and the fourth gear 9 and meshes with the first gear 5. The inner walls of the upper and lower card storage brackets 21 are respectively provided with inner tooth patterns 213 meshing with the third gear 8 and the fourth gear 9. When the driving motor 4 rotates, the first gear 5 is driven, and the first gear 5 then drives the second gear 7, and the third gear 8 and the fourth gear 9 rotate simultaneously and drive the upper and lower card storage brackets 21 to rotate.

[0037] A support frame 10 and a shuffling plate 11 are also provided on the shuffling plate 11. A shuffling motor (not shown) and a scraping strip 13 are provided on the shuffling plate 11. The shuffling motor drives the scraping strip 13 to rotate. The support frame 10 is located on the inner side of the card storage mechanism 2. The support frame 10 includes a first support portion 101, a second support portion 102, a third support portion 103, a left side plate 104 and a right side plate 105. Among them, the first support portion 101, the second support portion 102, and the third support portion 103 are all located on one side of the left side plate 104 and are all connected to the left side plate 104. A total transmission mechanism is provided on the support frame 10, and the total transmission mechanism is used to transmit the mahjong tiles on the shuffling plate 11 to the card grid 211. The total transmission mechanism includes a first transmission mechanism, a second transmission mechanism, a third transmission mechanism, and a reversing mechanism for transmitting the mahjong tiles from the first transmission mechanism to the second transmission mechanism or the third transmission mechanism.

[0038] The first transmission mechanism includes a first motor 14, a first transmission belt 15 and a roller group 16. The first motor 14 is arranged on a first motor mounting seat 1041 on one side of the end of the left side plate 104, and the first motor output shaft passes through the left side plate 104 and extends toward the right side plate 105. The roller group 16 is arranged between the left side plate 104 and the right side plate 105. The first transmission belt 15 is sleeved on the first motor output shaft and the roller group 16 and is driven by the first motor 14. The roller group 16 includes a first roller 161, and the first roller 161 is movably connected to the support frame 10. Specifically, a rotating shaft 162 is arranged at both ends of the first roller 161, and a waist-shaped groove 100 is arranged at the corresponding position of the rotating shaft 162 on the left side plate 104 and the right side plate 105, and the rotating shaft 162 is mounted in the waist-shaped groove 100 and can move up and down along the waist-shaped groove 100. The first transmission mechanism sucks the mahjong cards from the shuffle tray 11 onto the first transmission belt 15 by magnetic attraction. When the first motor 14 drives the first transmission belt 15 , the mahjong tiles move forward along with the first transmission belt 15 .

[0039] The second transmission mechanism includes a first channel 17, a second motor 18, and a second transmission belt 19 driven by the second motor 18. The first channel 17 is arranged above the third support portion 103 of the support frame 10, and one end of the first channel 17 is close to the card grid 211 of the lower card storage bracket 21. Preferably, the bottom surface of the first channel 17 is flush with the bottom surface of the card grid 211 of the lower card storage bracket 21. The other end of the first channel 17 extends in the direction of the first transmission belt 15. The second transmission belt 19 is arranged on one side of the first channel 17 and along the length direction of the first channel 17, and the second transmission belt 19 is located above the first transmission belt 15. When the mahjong tiles move with the first transmission belt 15, they are blocked by the second transmission belt 19 and change the direction of movement to enter the first channel 17, and continue to move forward along the first channel 17 to enter the card grid 211 of the lower card storage bracket 21 under the action of the second transmission belt 19.

[0040] The third transmission mechanism is arranged between the first transmission mechanism and the second transmission mechanism. The third transmission mechanism includes a second channel 20, a third motor 22, and a third transmission belt 24 driven by the third motor 22. The second channel 20 is located above the second support portion 102 and the second channel 20 is higher than the first channel 17. One end of the second channel 20 is close to the card grid 211 of the upper card storage bracket 21. Preferably, the bottom surface of the second channel 20 is flush with the bottom surface of the card grid 211 of the upper card storage bracket 21. The other end of the second channel 20 extends toward the first transmission belt 15 so that the mahjong tiles can reach the card grid 211 of the upper card storage bracket 21 through the second channel 20. The third transmission belt 24 is arranged along the length direction of the second channel 20 and is located above the first transmission belt 15. The size of the gap between the third transmission belt 24 and the first transmission belt 15 can be adjusted by a reversing mechanism. When the gap between the third transmission belt 24 and the first transmission belt 15 is smaller than the size of the mahjong tiles, the mahjong tiles are blocked by the third transmission belt 24 during movement and change the direction of movement, that is, the mahjong tiles are transferred from the first transmission belt 15 to the second channel 20 and continue to move forward along the second channel 20 under the action of the third transmission belt 24 into the card grid 211 of the upper card storage bracket 21.

[0041] The reversing mechanism includes a fourth motor 25 and two rocker arms 26. The fourth motor 25 is arranged on the left side plate 104 and is arranged on the same side as the first motor 14. The two rocker arms 26 are respectively located at both ends of the output shaft of the fourth motor 25. One end of the rocker arm 26 is connected to the output shaft of the fourth motor, and the other end of the rocker arm 26 is connected to the rotating shaft 162 of the first roller 161. After the rotating shaft 162 of the first roller 161 passes through the rocker arm 26, it moves up and down along the waist-shaped groove 100 under the drive of the fourth motor 25, thereby driving the first roller 161 to move up and down. When the fourth motor 25 rotates forward, the output shaft of the fourth motor 25 drives the rocker arm 26 to rotate counterclockwise, and the rotating shaft 162 moves upward along the waist-shaped groove 100, thereby driving the first roller 161 to move upward, and the gap between the first transmission belt 15 and the third transmission belt 24 becomes narrower, and the mahjong tiles cannot pass through. At this time, the mahjong tiles are transmitted from the first transmission mechanism to the third transmission mechanism and enter the card grid 211 of the upper card storage bracket 21. When the fourth motor 25 reverses, the fourth motor output shaft drives the rocker arm 26 to rotate clockwise, and the rotating shaft 162 moves downward along the waist-shaped groove 100, thereby driving the first roller 161 to move downward, and the gap between the first transmission belt 15 and the third transmission belt 24 becomes wider. After passing through the gap between the first transmission belt 15 and the third transmission belt 24, the mahjong tiles enter the second transmission mechanism and enter the card grid 211 of the lower card storage bracket 21.

[0042] In addition, it should be noted that, unless otherwise specified, the terms "first", "second", "third", "fourth", etc. in the specification are only used to distinguish the various components, elements, steps, etc. in the specification, and are not used to indicate the logical relationship or sequential relationship between the various components, elements, steps, etc. In the description of the present invention, the terms "upper", "lower", "vertical", "horizontal", "vertical", "top", "bottom", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
