Description

Technical Field

[0001] The present invention relates to the technical field of mahjong machine manufacturing, and particularly relates to a mahjong machine, a card-pushing head thereof, and a lifting mechanism for a card-blocking block. Background Art

[0002] Currently, fully automatic mahjong machines can integrate functions such as shuffling and dice-throwing, providing a lot of convenience for people to play cards. However, currently, most fully automatic mahjong machines are basically only provided with four outlets, and then the mahjong is conveyed to the mahjong table from the four outlets. During card-playing, manual card-pushing, card-cutting, and card-piling are still required, which is not only troublesome to operate, but also may result in incorrect card-cutting, and the cards have to be reshuffled.

[0003] To solve this problem, a Chinese invention patent with the patent number CN200920118048.7 discloses an automatic mahjong machine, which includes a mahjong machine tabletop and a main body disposed below the mahjong machine tabletop. An inner lattice board is provided inside the main body, and outer lattice boards are provided on the outer sides of the inner lattice board. The 4 outer lattice boards are connected by 4 arc transition sections to form an annular track for carrying mahjong tiles. Above the annular track, there is an annular pushing device for pushing mahjong tiles. A slide rail is provided below the card-pushing head, and the card-pushing head is driven by a motor to slide between the inner pushing port and the outer pushing port. On the mahjong machine tabletop directly above the 4 outer lattice boards, there are all provided tilting plate devices for guiding the mahjong tiles on the annular track to the mahjong machine tabletop. An automatic mahjong machine provided by the present invention enables each of the thirteen game participant's cards to be obtained on each of the four outer sides, so that the game participants can obtain a more convenient, fast, and comfortable gaming experience.

[0004] The card-lifting principle of this automatic mahjong machine is as follows: Initially, the card-pushing head of the card-pushing head is at the outer card-pushing port and pushes cards onto the outer lattice board. When 13 cards are pushed, the control system issues an instruction, and the card-pushing head drives the card-pushing head to move to the inner card-pushing port, and then the card-pushing head starts to push cards. After the card-pushing head has pushed a certain number of stacks (varying according to the total number of stacks in card-playing), the motor of the flat-pushing component rotates, driving the guide plate to drop, and then the second layer of cards is pushed. When 13 cards are pushed on all 4 outer lattice boards and all the card-pushing heads have moved to the inner card-pushing port, the control system issues a signal, and the wire rope motor starts to rotate, driving the cards to move on the annular track and reaching the position waiting for card-lifting. When the cards on 1 inner lattice board are stacked up, the conveying motor rotates in reverse to pour the remaining cards in the conveying device back into the large tray and send them to the card-lifting ports of other conveying devices until the cards on all 4 inner lattice boards are stacked up.

[0005] The disadvantages of this automatic mahjong machine are as follows:

[0006] 1) There are an outer pushing card opening and an inner pushing card opening in the conveying channel. The mahjong tiles pass through the inner pushing card opening first and then the outer pushing card opening. Therefore, when the pushing head is at the inner pushing card opening, the mahjong tiles may be left behind and reach the outer pushing card opening, causing the mahjong machine to jam.

[0007] 2) Another driving device such as a motor is required for the pushing head to move from the outer pushing card opening to the inner pushing card opening and from the inner pushing card opening to the outer pushing card opening, resulting in high costs.

[0008] The patent application document with the publication number CN107519637A discloses a mahjong machine and its card-dealing method. The mahjong machine includes four groups of card-picking and transporting systems arranged around the shuffling tray. The card-picking and transporting system includes a card-sending device for picking up mahjong tiles one by one from the shuffling tray and sending them out, a card-stacking device for stacking two mahjong tiles into a stack, a card-pushing device for pushing the mahjong tiles into the card storage slot, and a ramp card-dealing device for sending multiple stacks of arranged mahjong tiles onto the mahjong machine table along a ramp. The ramp card-dealing device includes a card-dealing component and a card-lifting component. The card-dealing component includes a card storage slot, and the card storage slot is bent in a large-angle arc, increasing the storage quantity of mahjong tiles in the card storage slot. The card-dealing component and the card-lifting component in the same group of card-picking and transporting systems are directly adjacent. The above mahjong machine can implement a phased card-dealing method. When storing mahjong tiles, the card-sending device picks up the mahjong tiles and the card-pushing device pushes them into the card storage slot. When the mahjong machine receives the first card-dealing signal, the card-lifting tray of the card-lifting device descends, and the card-dealing pushing head first pushes a part of the mahjong tiles in the card storage slot (usually six and a half stacks or thirteen mahjong tiles) onto the card-lifting tray. The card-lifting tray rises to deal these mahjong tiles onto the table, waiting for the player to take away the mahjong tiles on the table. After the mahjong machine receives the second card-dealing signal, the card-lifting tray descends again, and the card-dealing pushing head pushes the remaining mahjong tiles in the card storage slot onto the card-lifting tray. The card-lifting tray rises to deal the mahjong tiles onto the table. By adopting this phased card-dealing scheme of pushing twice, the function of an eight-port mahjong machine can be achieved with the structure of an existing four-port mahjong machine. However, since the card-dealing pushing head occupies the position of one stack of tiles in the card storage slot during the process of dealing cards to the card-lifting device, the length of the card storage slot required for 17 stacks of tiles is 18 - 19 stacks of tiles. When playing larger hands with this type of mahjong machine, the required track length of the mahjong machine is relatively long, and it cannot be achieved with a mahjong machine of the existing model size. Therefore, it is necessary to minimize the length of the card storage slot of the mahjong machine.

[0009] The invention patent with the publication number CN108635827A discloses a card - feeding structure of a three - layer mahjong machine, which includes an annular single - layer card track and an annular double - layer card track installed overlapping up and down. A motor base is installed on the single - layer card track. The motor base is equipped with a second motor through a gear, and the motor base is equipped with a first motor through a rotating shaft. The passive shaft on the motor base is connected with a single - layer card turntable through a bearing. The teeth of the single - layer card turntable are engaged with the gear. A single - layer card push rod is arranged on the single - layer card turntable. An adjustment card ring and a double - layer card push rod placed inside the adjustment card ring are installed on the double - layer card track. After three cards enter the card track, the second motor drives the gear to drive the single - layer card turntable to rotate, and the single - layer card push rod on the single - layer card turntable pushes the cards on the single - layer card track to the mahjong machine tabletop. After three cards enter the card track, the first motor drives the rotating shaft to drive the double - layer card push rod to rotate, and pushes the cards on the double - layer card track to the mahjong machine tabletop. For the mahjong machine with the above structure, three mahjong cards are stacked into a stack, and a stack of mahjong cards is divided into a single layer (one card) and a double layer (two cards stacked) and are respectively sent into the single - layer card track and the double - layer card track and then sent to the mahjong machine tabletop. This setting can effectively shorten the required length of the mahjong machine track. However, the occupied height of the card - feeding structure of the above - mentioned mahjong machine is relatively large, and the overall height of the mahjong machine using this structure is relatively large. Especially when playing with larger mahjong cards, the existing - sized mahjong machines cannot achieve this. Moreover, when dividing a stack of mahjong cards into a single layer (one card) and a double layer (two cards stacked) and respectively sending them into the single - layer card track and the double - layer card track, the required precision at the track boundary is extremely high, and even a slight deviation will cause the mahjong machine to jam. On the other hand, two motors are respectively used to directly or indirectly drive two card - pushing heads to push the mahjong cards in the single - layer card track and the double - layer card track, which increases the structural complexity and control complexity of the mahjong machine, and increases the production cost of the mahjong machine. Summary of the Invention

[0010] The purpose of the present invention is to provide a mahjong machine, its card - pushing head, and a blocking - card block lifting mechanism according to the deficiencies of the prior art. The blocking - card block lifting mechanism is driven by a card - pushing motor so that the blocking - card block has a staying position at a high level for mahjong cards to pass through, and has a staying position at a low level to block the passage of mahjong cards.

[0011] In order to achieve the above purposes, the present invention adopts the following technical solutions:

[0012] .A card blocking block lifting mechanism is installed on the head box. At least one card pushing motor and a card blocking block are also installed on the head box. The card blocking block is installed on the head box and is driven by the card pushing motor to lift up and down relative to the head box. Among them, a first card pushing position and a second card pushing position are arranged before and after in the mahjong tile conveying direction. The card blocking block is arranged between the first card pushing position and the second card pushing position and can lift up and down to block the mahjong tiles and allow the mahjong tiles to pass through. When the card pushing motor rotates forward, the card blocking block is located between the first card pushing position and the second card pushing position. When the card pushing motor rotates backward, the card blocking block is no longer located between the first card pushing position and the second card pushing position.

[0013] Preferably, it further includes a camshaft in transmission cooperation with the card pushing motor, and a one-way bearing A, a one-way bearing B, a first lifting wheel and a second lifting wheel sleeved on the camshaft. The outer surfaces of the first lifting wheel and the second lifting wheel are respectively in transmission connection with the card blocking block. The inner surface of the first lifting wheel is in transmission cooperation with the outer surface of the one-way bearing A. The inner surface of the second lifting wheel is in transmission cooperation with the outer surface of the one-way bearing B. When the card pushing motor rotates forward, it drives the first lifting wheel to rotate, and then the card blocking block is located between the first card pushing position and the second card pushing position. When the card pushing motor rotates backward, it drives the second lifting wheel to rotate, and then the card blocking block is no longer located between the first card pushing position and the second card pushing position.

[0014] Preferably, it further includes a rotating block and a baffle spring piece. The baffle spring piece is installed in the head box. A lifting block is provided on the lower surface of the card blocking block. One end of the rotating block is movably matched with the baffle spring piece, and the other end is hinged to the lifting block. A second baffle block is provided on the front side of the rotating block, and a first baffle block is provided on the rear side. The first baffle block and the second baffle block are fixedly connected or integrally formed with the rotating block. The first baffle block is movably matched with the first lifting wheel, and the second baffle block is movably matched with the second lifting wheel. The card pushing motor drives the first lifting wheel to rotate forward, thereby driving the rotating block to rotate, driving the lifting block to descend, and making the card blocking block have a staying position at a low position. The card pushing motor drives the second lifting wheel to rotate backward, thereby driving the rotating block to rotate, driving the lifting block to ascend, and making the card blocking block have a staying position at a high position.

[0015] Preferably, the rotating block is provided with a first staying surface and a second staying surface that cooperate with the baffle spring piece. An inclined angle is formed between the first staying surface and the second staying surface. When the driving motor drives the first lifting wheel to rotate forward, it can drive the rotating block to rotate from the second staying surface against the baffle spring piece to the first staying surface against the baffle spring piece, so that the card blocking block has a staying position at a low position. When the driving motor drives the second lifting wheel to rotate backward, it can drive the rotating block to rotate from the first staying surface against the baffle spring piece to the second staying surface against the baffle spring piece, so that the card blocking block has a staying position at a high position.

[0016] Preferably, a second connecting shaft is provided on the lifting block. The second connecting shaft is fixedly connected or integrally formed with the lifting block. A long hole is provided on the rotating block, and the second connecting shaft is movably matched with the long hole.

[0017] Preferably, the first lifting wheel and the second lifting wheel are circumferentially distributed in different regions on the camshaft.

[0018] Preferably, a first camshaft sleeve and a second camshaft sleeve which are integrally formed or separated are also fixed in the machine head box. The camshaft can rotate in the first camshaft sleeve and the second camshaft sleeve. A one-way bearing C is sleeved at the rear end of the first camshaft sleeve. The outer surface of the one-way bearing C is in transmission connection with the first lifting wheel. The one-way bearing C is used to limit the reverse rotation of the first lifting wheel. A one-way bearing D is sleeved at the front end of the second camshaft sleeve. The outer surface of the one-way bearing D is in transmission connection with the second lifting wheel. The one-way bearing D is used to limit the forward rotation of the second lifting wheel.

[0019] Preferably, the card blocking block includes a first card blocking portion consistent with the forward pushing direction of the first card pushing head and a second card blocking portion perpendicular to the forward pushing direction of the first card pushing head. The first card blocking portion and the second card blocking portion are fixedly connected or integrally formed, and the second card blocking portion is lower than the first card blocking portion.

[0020] A card pushing machine head includes a card blocking block lifting mechanism as described above.

[0021] A mahjong machine includes a card blocking block lifting mechanism as described above.

[0022] The technical effects of the present invention are as follows:

[0023] 1), in the present invention, through the drive of the card pushing motor, the card blocking block has a staying position at a high position for the mahjong tiles to pass through, and has a staying position at a low position to block the mahjong tiles from passing through.

DETAILED DESCRIPTION

[0065] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0066] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0067] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more, unless otherwise clearly specified.

[0068] In the present invention, unless otherwise clearly defined and limited, the terms "installed", "connected", "linked", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0069] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0070] In the present invention, the inside of the mahjong machine is centered around the center of the mahjong machine, and the outside is around the periphery of the mahjong machine.

[0071] In the present invention, the forward rotation and reverse rotation of a single motor only represent the opposite rotation directions of the single motor itself. That is, when one motor rotates forward and the other motor rotates in reverse, the rotation directions of the two motors may be the same or different.

[0072] Embodiment 1:

[0073] As Figures 1 - 3 shown, a mahjong machine includes a bottom plate 1, a mahjong machine tabletop 2, a shuffling tray 3 located in the center and its driving mechanism, and four groups of card-picking and transporting systems around the four sides of the shuffling tray 3. The card-picking and transporting system includes a card-sending device 4 for picking up mahjong tiles 10 one by one from the shuffling tray 3 and sending them out, a flat-pushing card-loading device 5 and a ramp card-loading mechanism 6 for sending the arranged mahjong tiles 10 onto the mahjong machine tabletop 2, and a card-pushing head 7 for pushing the mahjong tiles 10 to the flat-pushing card-loading device 5 and the ramp card-loading mechanism 6 respectively. Among them, the four flat-pushing card-loading devices 5 enclose a rectangular shape parallel to the edge of the tabletop, the four ramp card-loading mechanisms 6 enclose a rectangular shape parallel to the edge of the tabletop, and the ramp card-loading mechanism 6 is located outside the flat-pushing card-loading device 5.

[0074] The card-pushing head 7 can push a single mahjong tile 10 onto the flat-pushing card-loading device 5 until the first layer of mahjong tiles 10 on the flat-pushing card-loading device 5 is full, and then push the second layer of mahjong tiles 10 onto the first layer of mahjong tiles 10 by the card-pushing head 7, and then the flat-pushing card-loading device 5 pushes the cards out and raises them to the mahjong machine tabletop 2.

[0075] The pushing head 7 of the tile pushing mechanism can also move a single mahjong tile 10 on the ramp tile feeding mechanism 6 until the specified number of tiles is reached, and then the ramp tile feeding mechanism 6 pushes the tiles out and raises them onto the mahjong table 2 of the mahjong machine.

[0076] In this way, during the process of transporting the mahjong tiles 10, the entire mahjong machine always transports the mahjong tiles 10 in a single layer. This can significantly shorten the vertical distance for the mahjong tiles 10 to rise onto the mahjong table 2 of the mahjong machine. That is, for the ramp tile feeding mechanism 6, the slope of its ramp is significantly reduced, and thus the tile feeding process becomes smoother and more stable. For the pushing head 7 of the tile pushing mechanism, it no longer needs to perform the tile stacking action on the mahjong tiles 10, making the structure of the tile pushing mechanism simple and avoiding problems such as the mahjong tiles 10 being easily overturned during stacking. For the entire mahjong machine, it can make the four sets of tile picking and transporting systems arranged more compactly, thereby reducing the volume of the entire mahjong machine.

[0077] As Figures 4 - 5 shown, there are four inner tile outlets 25 and four outer tile outlets 26 on the mahjong table 2 of the mahjong machine. The four inner tile outlets 25 are rectangular openings and are parallel to the edge of the mahjong table 2. The four outer tile outlets 26 are located outside the inner tile outlets 25. The four outer tile outlets 26 are respectively located at the four corners or near the four corners of the mahjong table 2. The flat pushing tile feeding device 5 sends two layers of mahjong tiles 10 to the mahjong table 2 through the four inner tile outlets 25, and the ramp tile feeding mechanism 6 sends single-layer tiles to the mahjong table 2 through the four outer tile outlets 26.

[0078] In the embodiment of the present application, the distribution of the four inner tile outlets 25 has the following differences compared with that of the existing similar four-outlet mahjong machines: For the four-outlet mahjong machines, all the mahjong tiles 10 are transported to the mahjong table 2 through the four tile outlets. Therefore, the tile outlets of the four-outlet mahjong machines need to accommodate a complete stack of mahjong tiles 10. Moreover, currently, the tile stacking and pushing components of the four-outlet machine head are integrated, which relatively occupies more space, resulting in the minimum length of the tile supporting plate being not less than 540 mm. However, in the eight-outlet mahjong machine of the embodiment of the present application, the inner tile outlets 25 only need to accommodate at most the remaining stack of mahjong tiles 10 after the player grabs 12 - 13 tiles. In this way, the maximum length of the supporting plate can be no more than 458 mm. Such a setting can make the distance between the inner and outer openings farther and also leave space for the tile pushing component of the machine head. In the eight-outlet mahjong machine of the embodiment of the present application, to ensure that the overall performance of the mahjong machine is in a better state, the interval distance between the two opposite inner tile outlets 25 should be controlled within the range of 400 mm - 540 mm, and the width of the inner tile outlets 25 is controlled within the range of not exceeding 458 mm.

[0079] As Figure 14The shown tile pushing head 7 includes a head box 71, at least one tile pushing motor 72, a first tile pushing head 73, a second tile pushing head 74, a card blocking block 75, a first curve wheel 76 and a second curve wheel 77. The at least one tile pushing motor 72 is installed on the head box 71; the first tile pushing head 73 is installed on the head box 71 and is driven by the tile pushing motor 72 to translate and slide relative to the head box 71; the second tile pushing head 74 is installed on the head box 71 and is driven by the tile pushing motor 72 to translate and slide relative to the head box 71; the card blocking block 75 is installed on the head box 71 and is driven by the tile pushing motor 72 to move up and down relative to the head box 71; and a first tile pushing position 421 and a second tile pushing position 422 are arranged before and after in the conveying direction of the mahjong tiles 10. The card blocking block 75 is arranged between the first tile pushing position 421 and the second tile pushing position 422 and can move up and down to block the mahjong tiles 10 and allow the mahjong tiles 10 to pass through. The first tile pushing head 73 is located on one side of the first tile pushing position 421 and translates in and out of the first tile pushing position 421 to push the tiles. The second tile pushing head 74 is located on one side of the second tile pushing position 422 and translates in and out of the second tile pushing position 422 to push the tiles. Further preferably, the card feeding port of the flat tile feeding device 5 and the first tile pushing head 73 are respectively located on opposite sides of the first tile pushing position 421, and the card feeding port of the ramp tile feeding mechanism 6 and the second tile pushing head 74 are respectively located on opposite sides of the second tile pushing position 422; when the card blocking block 75 moves into the space between the first tile pushing position 421 and the second tile pushing position 422, the card blocking block 75 prevents the mahjong tiles 10 from entering the second tile pushing position 422, and the first tile pushing head 73 pushes the single mahjong tile 10 located at the first tile pushing position 421 into the card feeding port of the flat tile feeding device 5; when the card blocking block 75 moves out of the space between the first tile pushing position 421 and the second tile pushing position 422, the mahjong tiles 10 enter the second tile pushing position 422, and the second tile pushing head 74 pushes the single mahjong tile 10 located at the second tile pushing position 422 into the card feeding port of the ramp tile feeding mechanism 6.

[0080] Wherein, the first tile pushing position 421 refers to the position space outside the card discharging port of the card feeding device 4 for the first tile pushing head 73 to implement tile pushing. The second tile pushing position 422 refers to the position space outside the first tile pushing position 421 for the second tile pushing head 74 to implement tile pushing. The card blocking block 75 moving into the space between the first tile pushing position 421 and the second tile pushing position 422 means that the card blocking block 75 is within the space height of the first tile pushing position 421 and the second tile pushing position 422. The card blocking block 75 moving out of the space between the first tile pushing position 421 and the second tile pushing position 422 means that the card blocking block 75 is not within the space height of the first tile pushing position 421 and the second tile pushing position 422. In this embodiment, the conveyor belt of the card feeding device 4 extends to below the first tile pushing position 421 to form a first card supporting platform for storing the mahjong tiles 10.

[0081] Specifically, a first curve wheel 76, a second curve wheel 77 and a first mounting seat 78 are provided on the machine head box 71. The first mounting seat 78 is slidably connected to the machine head box 71 up and down. The blocking plate 75 is fixed on the first mounting seat 78. The first mounting seat 78 is drivingly connected to the first curve wheel 76. The first pusher head 73 is slidably connected to the first mounting seat 78 in translation. The second pusher head 74 is slidably connected to the machine head box 71 in translation. The first pusher head 73 and the second pusher head 74 are respectively drivingly connected to the second curve wheel 77. The first curve wheel 76 and the second curve wheel 77 are respectively drivingly connected to the pusher motor 72. The pusher motor 72 drives the first pusher head 73 and the blocking plate 75 to lift together through the first curve wheel 76. The pusher motor 72 drives the first pusher head 73 and / or the second pusher head 74 to push the cards through the second curve wheel 77. Further preferably, a seventh connecting block 782 is provided at the bottom of the first mounting seat 78. A fourth rolling bearing 781 is provided at the bottom of the seventh connecting block 782. A plurality of guide posts are further provided on the upper surface of the machine head box 71. The first mounting seat 78 is mounted on the guide posts in a liftable manner. When the first curve wheel 76 rotates, it can lift the fourth rolling bearing 781, so that the first mounting seat 78 rises stably through the guide posts, thereby causing the first pusher head 73 and the blocking plate 75 to rise.

[0082] Specifically, when the blocking plate 75 moves into the space between the first card pushing position 421 and the second card pushing position 422, the blocking plate 75 prevents the mahjong tiles 10 from entering the second card pushing position 422, and the first pusher head 73 pushes the single mahjong tile 10 located at the first card pushing position 421. When the blocking plate 75 moves out of the space between the first card pushing position 421 and the second card pushing position 422, the mahjong tiles 10 enter the second card pushing position 422, and the second pusher head 74 pushes the single mahjong tile 10 located at the second card pushing position 422, and the first pusher head 73 does not push the single mahjong tile 10 passing through the first card pushing position 421.

[0083] Specifically, a first connecting block 70 is provided in the machine head box 71. The lower part of the first connecting block 70 is hinged to the machine head box 71. The upper part of the first connecting block 70 is movably matched with the first pusher head 73 and / or the second pusher head 74. The first connecting block 70 is driven by the second curve wheel 77 to swing, so as to push the first pusher head 73 and / or the second pusher head 74 to push the cards.

[0084] Specifically, the card blocking block 75 includes a first card blocking portion 751 that is consistent with the forward pushing direction of the first card pushing head 73 and a second card blocking portion 752 that is perpendicular to the forward pushing direction of the first card pushing head 73. The first card blocking portion 751 and the second card blocking portion 752 are fixedly connected or integrally formed, and the second card blocking portion 752 is lower than the first card blocking portion 751. Further preferably, the distance between the highest point of the second card blocking portion 752 and the lowest point of the first card blocking portion 751 is less than the thickness of a mahjong tile 10. More preferably, the second card blocking portion 752 moves in and out between the first card pushing position 421 of the card feeding device 4 and the card feeding port of the horizontal card placing device 5 to achieve blocking or passing through, and the first card blocking portion 751 moves in and out between the first card pushing position 421 and the second card pushing position 422 to achieve blocking or passing through. The conveyor belt of the card feeding device 4 extends to the first card blocking portion 751 of the card blocking block 75 between the first card pushing position 421 and the second card pushing position 422. When the first card blocking portion 751 blocks between the first card pushing position 421 and the second card pushing position 422, the second card blocking portion 752 moves out between the first card pushing position 421 of the card feeding device 4 and the card feeding port of the horizontal card placing device 5, so that the first card pushing head 73 can push a single mahjong tile 10 located at the first card pushing position 421 into the card feeding port of the horizontal card placing device 5. When the first card blocking portion 751 moves out between the first card pushing position 421 and the second card pushing position 422, the second card blocking portion 752 enters between the first card pushing position 421 of the card feeding device 4 and the card feeding port of the horizontal card placing device 5 to prevent the mahjong tile 10 from entering the card feeding port of the horizontal card placing device 5.

[0085] Specifically, the second card pushing head 74 includes a sliding portion for sliding on the head box 71 and a card pushing portion for pushing the cards. The card pushing portion extends outward from the head box 71.

[0086] When there is one card pushing motor 72 in the card pushing head 7, a first connecting shaft 711 is provided at the bottom inside the head box 71. A first connecting block 70 that can rotate around the first connecting shaft 711 is sleeved on the first connecting shaft 711. A fifth rolling bearing 701 is provided at the lower part of the first connecting block 70, and at least one sixth rolling bearing 702 is provided at the upper part of the first connecting block 70. The fifth rolling bearing 701 can rotate relative to its axis and contact the second curve wheel 77, and the sixth rolling bearing 702 can rotate around its axis and at least contact the second card pushing head 74. Further preferably, a first sliding groove is provided on the first mounting seat 78, and the first card pushing head 73 can slide on the first sliding groove. A second sliding groove is provided on the upper surface of the head box 71, and the second card pushing head 74 can slide on the second sliding groove.

[0087] In order to simultaneously push the first card-pushing head 73 and the second card-pushing head 74 by rotating the first connecting block 70, the first implementation method is as follows: The first connecting block 70 is a Y-shaped block. Two sixth rolling bearings 702 are provided on the upper part of the first connecting block 70. The two sixth rolling bearings 702 are respectively in contact with the first card-pushing head 73 and the second card-pushing head 74. In this way, when the card-pushing motor 72 rotates forward to drive the second curve wheel 77 to rotate forward, the first connecting block 70 rotates to drive the second card-pushing head 74 to push forward, and the first card-pushing head 73 remains stationary or pushes forward. Further preferably, a third connecting block 731 is provided at the bottom of the first card-pushing head 73, and a fourth connecting block 741 is provided at the bottom of the second card-pushing head 74. The third connecting block 731 is fixedly connected to the first card-pushing head 73 or integrally formed therewith, and the fourth connecting block 741 is fixedly connected to the second card-pushing head 74 or integrally formed therewith. The two sixth rolling bearings 702 are respectively in contact with the vertical surfaces of the third connecting block 731 and the fourth connecting block 741.

[0088] In order to simultaneously push the first card-pushing head 73 and the second card-pushing head 74 by rotating the first connecting block 70, the second implementation method is as follows: A sixth rolling bearing 702 is provided on the upper part of the first connecting block 70. The sixth rolling bearing 702 is in contact with the second card-pushing head 74. A third sliding groove in the vertical direction is provided on the second card-pushing head 74. The first card-pushing head 73 can slide up and down on the third sliding groove. In this way, when the card-pushing motor 72 rotates forward to drive the second curve wheel 77 to rotate forward, the first connecting block 70 rotates to drive the second card-pushing head 74 to push forward, and the first card-pushing head 73 remains stationary or pushes forward. Further preferably, a fifth connecting block is provided at the bottom of the first card-pushing head 73, and a sixth connecting block is provided at the bottom of the second card-pushing head 74. The fifth connecting block is fixedly connected to the first card-pushing head 73 or integrally formed therewith, and the sixth connecting block is fixedly connected to the second card-pushing head 74 or integrally formed therewith. The sixth connecting block is an L-shaped block. A third sliding groove in the vertical direction is provided at the end of the sixth connecting block. The fifth sliding groove can slide up and down on the third sliding groove.

[0089] In order to make the first card-pushing head 73 and the second card-pushing head 74 push forward and then return to their original positions, the first implementation method is as follows: A first tension spring and a second tension spring are further provided. One end of the first tension spring is connected to the first card-pushing head 73, and the other end is connected to the first mounting seat 78 or the machine head box 71. One end of the second tension spring is connected to the second card-pushing head 74, and the other end is connected to the machine head box 71. When the first card-pushing head 73 and the second card-pushing head 74 push forward and then return, the first tension spring and the second tension spring respectively pull the first card-pushing head 73 and the second card-pushing head 74 back to their original positions; Further preferably, a first positioning post is provided on the first card-pushing head 73, and a second positioning post is provided on the upper surface of the first mounting seat 78 or the machine head box 71. The connection line between the first positioning post and the second positioning post is consistent with the forward-pushing direction of the first card-pushing head 73. One end of the first tension spring is sleeved on the first positioning post, and the other end is sleeved on the second positioning post. In this way, when the first card-pushing head 73 pushes forward and then returns, the first tension spring can pull it back to its original position. The second tension spring also connects the second card-pushing head 74 and the machine head box 71 through the positioning post, so that when the second card-pushing head 74 pushes forward and then returns, the second tension spring can pull it back to its original position.

[0090] In order to make the first card-pushing head 73 and the second card-pushing head 74 push forward and then return to their original positions, the second implementation method is as follows: The surfaces of the first card-pushing head 73 and / or the second card-pushing head 74 in contact with the sixth rolling bearing 702 are respectively a first contact surface and a second contact surface. The first contact surface and the second contact surface are perpendicular to the forward-pushing direction of the first card-pushing head 73 and the second card-pushing head 74. When the second cam wheel 77 rotates to make the sixth rolling bearing 702 or the seventh rolling bearing exert a force on the first contact surface, the second card-pushing head 74 pushes forward, and the first card-pushing head 73 is stationary or pushes forward. When the second cam wheel 77 rotates to make the sixth rolling bearing 702 or the seventh rolling bearing exert a force on the second contact surface, the first card-pushing head 73 and the second card-pushing head 74 return to their original positions. In this way, there is no need to set a tension spring for resetting, which saves costs. Further preferably, an eighth connecting block is provided at the bottom of the first card-pushing head 73, and a ninth connecting block is provided at the bottom of the second card-pushing head 74. The eighth connecting block is fixedly connected to the first card-pushing head 73 or integrally formed therewith. The ninth connecting block is fixedly connected to the second card-pushing head 74 or integrally formed therewith. The eighth connecting block is parallel to the third connecting block 731 or the fifth connecting block. The ninth connecting block is parallel to the fourth connecting block 741 or the sixth connecting block;

[0091] When the first card pushing head 73 and the second card pushing head 74 are pushed forward by adopting the first implementation manner, one of the sixth rolling bearings 702 is clamped between the eighth connecting block and the third connecting block 731 or the fifth connecting block, and the other sixth rolling bearing 702 is clamped between the ninth connecting block and the fourth connecting block 741 or the sixth connecting block. The surfaces of the third connecting block 731 and the fourth connecting block 741 in contact with the sixth rolling bearing 702 are the first contact surfaces, or the surfaces of the fifth connecting block and the sixth connecting block in contact with the sixth rolling bearing 702 are the first contact surfaces. The surfaces of the eighth connecting block and the ninth connecting block in contact with the sixth rolling bearing 702 are the second contact surfaces;

[0092] When the first card pushing head 73 and the second card pushing head 74 are pushed forward by adopting the second implementation manner, the sixth rolling bearing 702 is clamped between the ninth connecting block and the fourth connecting block 741 or the sixth connecting block. The surface of the sixth connecting block or the fourth connecting block 741 in contact with the sixth rolling bearing 702 is the first contact surface, and the surface of the ninth connecting block in contact with the sixth rolling bearing 702 is the second contact surface.

[0093] Specifically, the first cam wheel 76 and the second cam wheel 77 are fixedly connected or integrally formed.

[0094] When there are two card pushing motors 72 in the card pushing head 7, that is, including the first card pushing motor 72 and the second card pushing motor 72, the first card pushing motor 72 and the second card pushing motor 72 are respectively located on both sides of the head box 71. The first card pushing motor 72 is used to drive the first mounting seat 78 to move up and down, so as to control the up and down movement of the card blocking block 75 and the first card pushing head 73. The second card pushing motor 72 drives the second connecting block to rotate. The upper part of the second connecting block is movably matched with the first card pushing head 73 and / or the second card pushing head 74, so that the second card pushing head 74 is pushed forward, and the first card pushing head 73 is stationary or pushed forward.

[0095] Among them, there are two ways for the first card pushing head 73 and the second card pushing head 74 to return to their original positions after being pushed forward, which are the same as the ways for the first card pushing head 73 and the second card pushing head 74 to return to their original positions after being pushed forward in one card pushing motor 72.

[0096] Such as Figure 3The shown card delivery device 4 includes a card delivery box 41. A guide plate is provided in front of the card inlet of the card delivery box 41. A card inlet wheel with a magnet is provided at the card inlet of the card delivery box 41. A tension wheel and a driving wheel are provided in the card delivery box 41. A card outlet wheel is provided at the card outlet of the card delivery box 41. A conveyor belt is wound around the card inlet wheel, the card outlet wheel and the driving wheel and is tensioned by the tension wheel. A card aligning guide groove is provided at the card inlet. The width of the card inlet is slightly larger than the width of the selected mahjong tile 10 and shorter than the length of the mahjong tile 10. The height of the card inlet is larger than the thickness of the mahjong tile 10 and smaller than the width of the mahjong tile 10. One, two, three or four magnets are embedded in the card inlet wheel. The part of the outer circumferential surface of the card inlet wheel opposite to the magnet is designed as a plane corresponding to the size of the mahjong tile 10. After the rotation of the card inlet wheel, the mahjong tiles 10 are uniformly face-down, and after passing through the card aligning guide groove, they enter the card delivery device 4 in the length direction of the mahjong tile 10.

[0097] The running path of the mahjong tile 10 in the card delivery device 4 is a card delivery channel 42. The card delivery channel 42 starts from the card inlet of the card delivery box 41 and ends at the card outlet of the card delivery box 41. The card delivery channel 42 is a straight channel. The card outlet of the card delivery channel 42 is connected to the ramp card placement mechanism 6. When the mahjong tile 10 is conveyed to the card outlet of the card delivery channel 42, it is transported to the ramp card placement mechanism 6 through the card outlet wheel. Along the direction of sending out the mahjong tile 10, a first card pushing position 421 and a second card pushing position 422 are sequentially provided outside the card outlet of the card delivery channel 42. The card inlet of the flat card placement device 5 and the first card pushing head 73 are respectively located on the opposite sides of the first card pushing position 421. The card inlet of the ramp card placement mechanism 6 and the second card pushing head 74 are respectively located on the opposite sides of the second card pushing position 422. When the blocking block 75 moves into the space between the first card pushing position 421 and the second card pushing position 422, the blocking block 75 prevents the mahjong tile 10 from entering the second card pushing position 422, and the first card pushing head 73 pushes the single mahjong tile 10 located at the first card pushing position 421 into the card inlet of the flat card placement device 5. When the blocking block 75 moves out of the space between the first card pushing position 421 and the second card pushing position 422, the mahjong tile 10 enters the second card pushing position 422, and the second card pushing head 74 pushes the single mahjong tile 10 located at the second card pushing position 422 into the card inlet of the ramp card placement mechanism 6.

[0098] Specifically, the second card blocking part 752 moves in and out between the first card pushing position 421 of the card feeding device 4 and the card feeding port of the horizontal card pushing and placing device 5 to achieve blocking or passing through. The first card blocking part 751 moves in and out between the first card pushing position 421 and the second card pushing position 422 to achieve blocking or passing through. The conveyor belt of the card feeding device 4 extends to the first card blocking part 751 of the card blocking block 75 between the first card pushing position 421 and the second card pushing position 422. When the first card blocking part 751 blocks between the first card pushing position 421 and the second card pushing position 422, the second card blocking part 752 moves out between the first card pushing position 421 of the card feeding device 4 and the card feeding port of the horizontal card pushing and placing device 5, so that the first card pushing head 73 can push a single mahjong tile 10 located at the first card pushing position 421 into the card feeding port of the horizontal card pushing and placing device 5. When the first card blocking part 751 moves out between the first card pushing position 421 and the second card pushing position 422, the second card blocking part 752 enters between the first card pushing position 421 of the card feeding device 4 and the card feeding port of the horizontal card pushing and placing device 5 to prevent the mahjong tile 10 from entering the card feeding port of the horizontal card pushing and placing device 5.

[0099] There are also at least two in-place detection devices. One in-place detection device is located on the first card pushing head 73, and the other in-place detection device is located in the ramp card placing mechanism 6.

[0100] The specific process of a card pushing motor 72 coaxially driving the first curve wheel 76 and the second curve wheel 77 to enable the mahjong tiles 10 to enter the horizontal card pushing and placing device 5 and the ramp card placing mechanism 6 respectively is as follows:

[0101] As Figure 15 shown, when the horizontal card pushing and placing device 5 feeds cards, the initial position of the card blocking block 75 is at a low position, that is, when the first card blocking part 751 is between the first card pushing position 421 and the second card pushing position 422, when the card feeding device 4 conveys the mahjong tile 10 to the first card pushing position 421, the mahjong tile 10 is blocked by the first card blocking part 751, and after the in-place detection device located on the first card pushing head 73 senses the mahjong tile 10, as Figure 16As shown, the pushing motor 72 rotates forward to drive the first cam wheel 76 and the second cam wheel 77 to rotate forward. Among them, the first cam wheel 76 moves along a concentric circle curve, and the second cam wheel 77 moves along an ascending curve, driving the first connecting block 70 to rotate around the first connecting shaft 711 and causing the first pushing head 73 and the second pushing head 74 to push forward. At this time, the first blocking portion 751 is still located between the first pushing position 421 and the second pushing position 422, that is, the gap between the first blocking portion 751 and the card feeding track is smaller than the height of the mahjong tile 10. The second blocking portion 752 is located below the card feeding port of the flat pushing card loading device 5. The first pushing head 73 pushes a single mahjong tile 10 from the first pushing position 421 into the flat pushing card loading device 5, and the second pushing head 74 makes an empty push. Then the pushing motor 72 rotates reversely, and the first pushing head 73 and the second pushing head 74 return to their original positions and wait for pushing. This action is repeated until the specified number of mahjong tiles 10 is reached in the flat pushing card loading device 5;

[0102] After the flat pushing card loading device 5 is fully loaded with cards, as Figure 17 shown, the pushing motor 72 rotates reversely to drive the first cam wheel 76 and the second cam wheel 77 to rotate. Among them, the first cam wheel 76 moves along an ascending curve, and the second cam wheel 77 moves along a concentric circle curve, driving the blocking block 75, the first mounting seat 78 and the first pushing head 73 to rise. That is, the gap between the first blocking portion 751 and the card feeding track is larger than the height of the mahjong tile 10. The second blocking portion 752 enters the space between the first pushing position 421 of the card feeding device 4 and the card feeding port of the flat pushing card loading device 5 to prevent the mahjong tile 10 from entering the card feeding port of the flat pushing card loading device 5. The mahjong tile 10 enters the second pushing position 422. In addition, at this time, since the first pushing head 73 rises, the third connecting block 731 at its bottom no longer contacts the sixth rolling bearing 702 or the third connecting block 731 and the eighth connecting block no longer contact the sixth rolling bearing 702.

[0103] As Figure 18 shown, the pushing motor 72 continues to rotate reversely to drive the first cam wheel 76 and the second cam wheel 77 to rotate. Among them, the first cam wheel 76 moves along a concentric circle curve, and the second cam wheel 77 moves along an ascending curve, driving the first connecting block 70 to rotate around the first connecting shaft 711 and causing the second pushing head 74 to push forward. At this time, the blocking block 75 has moved out of the space between the first pushing position 421 and the second pushing position 422, that is, a single mahjong tile 10 has entered the second pushing position 422 and is then pushed by the second pushing head 74. The first pushing head 73 remains stationary. Then the pushing motor 72 rotates forward, and the first pushing head 73 and the second pushing head 74 return to their original positions. This action is repeated until the specified number of mahjong tiles 10 is reached in the ramp card loading mechanism 6.

[0104] When there are two pushing motors 72 in the pushing head 7, the pushing process is as follows:

[0105] When the first card blocking portion 751 is located between the first card pushing position 421 and the second card pushing position 422, the second card pushing motor 72 rotates forward to drive the second connecting block to rotate, so that the second card pushing head 74 pushes forward and the first card pushing head 73 pushes forward; then the second card pushing motor 72 reverses and returns to its original position, and the first card pushing head 73 and the second card pushing head 74 return to their original positions; this action is repeated until the number of mahjong tiles 10 in the horizontal pushing device 5 reaches the specified number;

[0106] After the horizontal push card loading device 5 is fully loaded, the first card pushing motor 72 rotates forward to make the first card pushing head 73 and the card blocking block 75 rise; that is, the first card blocking portion 751 moves out from between the first card pushing position 421 and the second card pushing position 422, and the second card blocking portion 752 enters between the first card pushing position 421 of the card feeding device 4 and the card inlet of the horizontal push card loading device 5, and the mahjong tile 10 enters the second card pushing position 422;

[0107] The second card pushing motor 72 rotates forward to drive the second connecting block to rotate, so that the second card pushing head 74 is pushed forward and the first card pushing head 73 is stationary; then the second card pushing motor 72 is reversed and returns to its original position, and the second card pushing head 74 returns to its original position; this action is repeated until the number of mahjong tiles 10 in the ramp card loading mechanism 6 reaches the specified number;

[0108] The first card pushing motor 72 reverses and returns to its original position, causing the first card pushing head 73 and the card blocking block 75 to descend and return to their original positions.

[0109] like Figures 6 - 13 The flat-push card loading device 5 shown is the first implementation mode of the embodiment of the present application, which completes the card loading by first lifting the card and then pushing the card. In this implementation mode, the flat-push card loading device 5 includes a lattice plate 51, and a first card loading motor 52, a card supporting plate 553, a card pushing mechanism and a lifting mechanism installed on the lattice plate 51. The card supporting plate 553 is connected to the lattice plate 51 for sliding up and down, and the card pushing mechanism and the lifting mechanism are respectively connected to the first card loading motor 52 for transmission; it is characterized in that: the first card loading motor 52 drives the card supporting plate 553 to rise and fall through the lifting mechanism, and when the card supporting plate 553 rises to be flush with the mahjong machine table top 2, the first card loading motor 52 pushes the mahjong tiles 10 on the card supporting plate 553 onto the mahjong machine table top 2 through the card pushing mechanism; the lattice plate 51 A seesaw 56 is also provided on the top, which is located on the card-feeding side of the card-supporting plate 553 and is offset from the card-supporting plate 553. One end of the seesaw 56 is hinged to the lattice plate 51, and the other end of the seesaw 56 is driven by the first card-loading motor 52 to be lifted or lowered.

[0110] Specifically, the movable end of the seesaw 56 has two resting positions, namely, tilted upward and laid flat. When the seesaw 56 is tilted upward, the height of the highest point of the seesaw 56 from the upper surface of the card support plate 553 is not less than the thickness of a single mahjong tile 10. When the seesaw 56 is laid flat, the seesaw 56 is flush with the upper surface of the card support plate 553.

[0111] Specifically, the first card - placing motor 52 is drivingly connected to the card - pushing mechanism and the lifting mechanism through a gear transmission device. The gear transmission device includes a left lifting gear 531, a driving gear 532, a pushing - pulling gear 533, and a right lifting gear 534 that are sequentially meshed with each other and installed on the lattice plate 51. The driving gear 532 is connected to the output shaft of the first card - placing motor 52. The lifting mechanism includes two lifting cranks 554. A support frame 555 with a bottom cam curve is provided under the card - supporting plate 553. The movable ends of the two lifting cranks 554 are respectively cooperated and supported with the bottom cam curve of the support frame 555. The two lifting cranks 554 are respectively installed on the left lifting gear 531 and the right lifting gear 534. The card - pushing mechanism includes a card - pushing cam 541, a transmission main shaft 542, two card - pushing rockers 543, a card - pushing plate 544, and a first connecting member 545. The card - pushing cam 541 is fixedly connected to the pushing - pulling gear 533. One end of the first connecting member 545 is in driving cooperation with the card - pushing cam 541. The other end of the first connecting member 545 is fixed on the transmission main shaft 542. The transmission main shaft 542 is installed on the lattice plate 51 and can rotate. The lower ends of the two card - pushing rockers 543 are respectively fixed on the transmission main shaft 542. The upper ends of the two card - pushing rockers 543 jointly push the card - pushing plate 544 to move. The card - pushing plate 544 is fixed on a flat - pushing slider. The flat - pushing slider is slidably connected to the card - pushing support 546. The flat - pushing slider is driven by the card - pushing rocker 543 to translate. The card - pushing support 546 is fixedly connected to the card - supporting plate 553 and synchronously lifted and lowered.

[0112] It should be noted that, to ensure good transmission effect, the transmission main shaft 542, the two card - pushing rockers 543, and the first connecting member 545 are integrally formed by injection molding during the processing.

[0113] Specifically, a rocker cam 57 and a rocker 56 gear coaxially fixed with the rocker cam 57 are installed on the lattice plate 51. The rocker 56 gear is in transmission cooperation with the left lifting gear 531 or the right lifting gear 534.

[0114] It should be noted that the rocker cam 57 can also be installed on the lifting crank 554 and integrally formed with the lifting crank 554. The lower surface of the rocker 56 is provided with a first convex portion that cooperates with the rocker cam 57. Through the rotation of the lifting crank 554 and the cooperation between the rocker cam 57 and the first convex portion, the rocker 56 can still have two staying positions of tilting upward and lying flat.

[0115] Specifically, the left lifting gear 531 or the right lifting gear 534 is a double - layer gear. One layer of teeth is a complete tooth and is in meshing transmission with the driving gear 532 or the pushing - pulling gear 533, and the other layer of teeth is an incomplete tooth and is in meshing transmission with the rocker 56 gear.

[0116] Specifically, the card-pushing support 546 is installed below the card-holding plate 553. Two sliding rods 547 are fixed on the card-pushing support 546. The flat-pushing slider slides on the sliding rods 547 and is reset by a spring. Two extending parts 5481 extend upward from the flat-pushing slider. The card-pushing plate 544 is installed on the two extending parts 5481. Third rolling bearings 5431 are provided at the tops of the two card-pushing rockers 543. When the card-pushing support 546 and the card-holding plate 553 rise, the two third rolling bearings 5431 are respectively in contact with both sides of the flat-pushing slider.

[0117] As Figure 7 and Figure 8 shown, in this embodiment, the card-stacking process is as follows: When the seesaw 56 tilts upward, the height difference between the highest point and the lowest point of the seesaw 56 is at least the thickness of a single mahjong tile 10, and the tilted end of the seesaw 56 is connected to the first card-pushing position 421. In this way, the first card-pushing head 73 can push the mahjong tile 10 onto the card-holding plate 553. When the first layer of mahjong tiles 10 is full, the seesaw 56 is flattened. At this time, the seesaw 56 is flush with the upper surface of the card-holding plate 553, and the upper surface of the single-layer mahjong tiles 10 is flush with or slightly lower than the first card-pushing position 421. The first card-pushing head 73 can continue to push the cards until the mahjong tiles 10 reach the specified number of stacks, completing the card stacking.

[0118] As Figure 9 shown is a schematic diagram of the card-holding plate 553 starting to rise during the card-lifting process of the flat-pushing card-loading device 5. As Figure 10 shown is a schematic diagram of the card-holding plate 553 rising to the highest position, that is, flush with or slightly higher than the mahjong tabletop 2 during the card-lifting process of the flat-pushing card-loading device 5. As Figure 11 shown is a schematic diagram of the card-holding plate 553 rising to the highest position and the card-pushing plate 544 having been pushed to the farthest position during the card-lifting process of the flat-pushing card-loading device 5. As Figure 12 shown is a schematic diagram of the card-holding plate 553 rising to the highest position and the card-pushing plate 544 having returned to its original position during the card-lifting process of the flat-pushing card-loading device 5. As Figure 13 shown is a schematic diagram of the card-holding plate 553 descending and the seesaw 56 still being in the flattened state after the card-pushing of the flat-pushing card-loading device 5 is completed.

[0119] Specifically, the first way for the flat-pushing card-dealing device 5 to lift the cards first and then push the cards is as follows: There are four first inner card outlets 25 and first covers arranged in a rectangular distribution on the mahjong table 2 of the mahjong machine. The upper surface of the first cover is flush with the mahjong table 2 and seals the first inner card outlet 25. A plurality of first ejector rods are also distributed on the card-supporting plate 553. The first cover is connected to the first ejector rods. The first card-dealing motor 52 drives two lifting cranks 554 to rotate, causing the card-supporting plate 553 to rise, and further causing a plurality of first ejector rods to lift the first cover. When the card-supporting plate 553 rises to be flush with or higher than the tabletop, the card-pushing rocker 543 pushes the card-pushing plate 544 to push out the mahjong tiles 10; further preferably, the first cover is fixedly connected or integrally formed with the first ejector rods; it should be noted that the first cover can also be lifted by the mahjong tiles 10.

[0120] Specifically, the second way for the flat-pushing card-dealing device 5 to lift the cards first and then push the cards is as follows: There are four second inner card outlets 25 and second covers arranged in a rectangular distribution on the mahjong table 2 of the mahjong machine. The upper surface of the second cover is flush with the mahjong table 2 and seals the second inner card outlet 25. At least two second ejector rods are distributed on the card-supporting plate 553. One side of the second cover is hinged to the mahjong table 2 and the other side can be lifted by at least two second ejector rods. The first card-dealing motor 52 drives two lifting cranks 554 to rotate, causing the card-supporting plate 553 to rise, and further causing at least two second ejector rods to lift the second cover. When the card-supporting plate 553 rises to be flush with or higher than the tabletop, the card-pushing rocker 543 pushes the card-pushing plate 544 to push out the mahjong tiles 10; it should be noted that the second cover can also be lifted by the mahjong tiles 10.

[0121] In the embodiment of this application, the flat-pushing card-dealing device 5 is the second implementation manner, which still adopts the card-dealing method of lifting the cards first and then pushing the cards. The difference between this implementation manner and the first implementation manner is that there is no seesaw 56 and the structures related to the seesaw 56.

[0122] In this implementation manner, the card-stacking process is as follows: In the initial state, the card-supporting plate 553 has a height matching the first card-pushing position 421. The first card-pushing head 73 can push the mahjong blocks through the first card-pushing position 421 onto the card-supporting plate 553. When the first layer of mahjong tiles 10 is fully covered, the first card-dealing motor 52 drives the lifting crank 554 to rotate, causing the card-supporting plate 553 to descend by the thickness of one mahjong tile 10. Then the first card-pushing head 73 can continue to push the cards until the mahjong tiles 10 reach the specified number of stacks, completing the card-stacking.

[0123] The card-lifting method can adopt the card-lifting method of the flat-pushing card-loading device 5 in the first embodiment. However, during the card-stacking process, the card-supporting plate 553 has a downward movement. If the first cover plate and the first ejector rod are fixedly connected or integrally formed, then when the card-supporting plate 553 descends, it will also drive the first cover plate to descend, which is obviously not advisable. Therefore, to avoid this situation, the first cover plate and the first ejector rod are movably connected, so that when the card-supporting plate 553 rises and falls within a certain height range, it will not drive the first cover plate to rise and fall, and when the card-supporting plate 553 exceeds this height range, the rising and falling of the card-supporting plate 553 can drive the first cover plate to rise and fall.

[0124] The flat-pushing card-loading device 5 in the embodiment of this application is the third embodiment. The difference between this embodiment and the first embodiment is that it adopts a card-loading method of first pushing the cards and then lifting the cards, that is, the lifting mechanism is not used to control the lifting of the card-supporting plate 553, but is used to control the lifting of the cover plate on the mahjong table 2. The specific structure can refer to the Chinese patent document with the publication number CN104436635A.

[0125] Its card-stacking process is the same as that of the first embodiment.

[0126] Its card-lifting process is as follows: After card-stacking is completed, the lifting mechanism controls the cover plate to descend to a height matching the card-supporting plate 553, then the card-pushing mechanism pushes the mahjong tiles 10 onto the cover plate, and then the lifting mechanism controls the cover plate to rise to a height flush with the mahjong table 2 to complete card-lifting.

[0127] The flat-pushing card-loading device 5 in the embodiment of this application is the fourth embodiment. The difference between this embodiment and the third embodiment is that there is no tipping plate 56 and the structures related to the tipping plate 56. The specific structure can refer to the Chinese patent document with the publication number CN201271493Y.

[0128] Its card-stacking method is the same as that of the second embodiment.

[0129] Its card-lifting method is the same as that of the third embodiment.

[0130] It should be noted that the biggest difference between the flat-pushing card-loading device 5 in the first embodiment and the second embodiment and the flat-pushing card-loading device 5 in the third embodiment and the fourth embodiment is that:

[0131] In the first and second embodiments, the mahjong tiles 10 in the flat push tile placing device 5 are first lifted onto the mahjong machine table 2 and then the push tile rocker 543 pushes the push tile plate 544 to push out the mahjong tiles 10. While in the third and fourth embodiments, the mahjong tiles 10 in the flat push tile placing device 5 are first pushed out by the push tile rocker 543 pushing the push tile plate 544 and then lifted onto the mahjong machine table 2. That is, the space occupied by pushing out the mahjong tiles 10 in the flat push tile placing device 5 in the first and second embodiments is transferred to the mahjong machine table 2 of the mahjong machine, thereby making the internal space of the mahjong machine more abundant, and further reducing the volume of the mahjong machine.

[0132] As Figure 19 and Figure 22 shown, the ramp tile placing mechanism 6 is the first embodiment of the embodiments of the present application. In this embodiment, the ramp tile placing mechanism 6 includes a tile placing drive mechanism and a tile placing support. The tile placing support is provided with a first tile placing guide rail 63 for storing mahjong tiles 10 and a tile placing push head 612 that moves along the first tile placing guide rail 63 to implement tile placing. The first tile placing guide rail 63 stores a single layer of mahjong tiles 10 arranged along the width direction of the mahjong tiles 10, and a section of the first tile placing guide rail 63 close to the tile outlet on the mahjong machine table 2 is a ramp section that extends obliquely upward to connect with the mahjong machine table 2. The tile placing drive mechanism includes a tile placing chain 611. The tile placing push head 612 is installed on the tile placing chain 611. The tile placing chain 611 moves along the bottom groove of the first tile placing guide rail 63 and matches the tile placing trajectory of the mahjong tiles 10. A first flap 23 is provided at the tile outlet on the mahjong machine table 2. One side of the first flap 23 is hinged to the mahjong machine table 2 or the tile placing support. The tile placing chain 611 moves to drive the tile placing push head 612 to move, thereby pushing the mahjong tiles 10 to advance along the first tile placing guide rail 63 and lifting the other side of the first flap 23, and then pushing the mahjong tiles 10 along the ramp section onto the mahjong machine table 2.

[0133] Specifically, the tile placing push head 612 is slidably connected to the tile placing chain 611 up and down through two lifting rods 6122. The tile placing push head 612 is fixed or integrally formed at the upper ends of the two lifting rods 6122. A base 6121 is fixed or integrally formed at the lower ends of the two lifting rods 6122. The two lifting rods 6122 pass through the links of the tile placing chain 611 and are respectively sleeved with spring members 6124. The lower ends of the spring members 6124 abut against the base 6121, and the upper ends abut against the tile placing chain 611. A roller 6125 is further provided on the base 6121, and a first guide rail 64 that cooperates with the roller 6125 is further provided on the tile placing support. The first guide rail 64 is located below the ramp section of the first tile placing guide rail 63.

[0134] Specifically, the first card-loading guide rail 63 includes an inner guide rail 631 and an outer guide rail 632 distributed on the inner and outer sides of the bottom groove. The inner guide rail 631 includes a horizontal first linear guide rail 6311 and an upwardly inclined first arc guide rail 6312. The outer guide rail 632 includes a horizontal second linear guide rail 6321 and an upwardly inclined second arc guide rail 6322. Further preferably, the inner guide rail 631 and the outer guide rail 632 are integrally formed by injection molding. Specifically, a groove for accommodating the card-loading chain 611 and the card-loading pusher head 612 is provided between the first linear guide rail 6311 and the second linear guide rail 6321 to connect them into one body, which is convenient for installation and can improve the fitting accuracy of the inner guide rail 631 and the outer guide rail 632.

[0135] Specifically, the pushing surface on the card-loading pusher head 612 includes a vertical surface and an inclined surface 61232. Further preferably, the vertical surface and the inclined surface 61232 are smoothly transitioned. When the card-loading pusher head 612 pushes the cards in the first card-loading guide rail 63, the pushing surface is the vertical surface in the horizontal first linear guide rail 6311 and the second linear guide rail 6321, while the pushing surface is the inclined surface 61232 in the upwardly inclined first arc guide rail 6312 and the second arc guide rail 6322.

[0136] Specifically, the first card-loading guide rail 63 is made of a material with a smooth and wear-resistant surface, such as polyoxymethylene, polytetrafluoroethylene, etc., or a smooth and wear-resistant patch is installed on the first card-loading guide rail 63. The first card-loading guide rail 63 is installed on the card-loading bracket as an independent component, and the card-loading bracket is made of a material with poor performance and low price, which can not only meet the use requirements but also reduce the manufacturing cost of the machine. The first card-loading guide rail 63 is preferably positioned in cooperation with the card-loading bracket through a plurality of T-shaped convexes and locked and fixed by fasteners for convenient installation.

[0137] Specifically, one side of the first flap 23 is hinged to the mahjong tabletop 2 of the mahjong machine through a hinge. The fixed part of the hinge is fixedly connected to the bottom of the mahjong tabletop 2 of the mahjong machine, the movable part of the hinge is fixedly connected to the bottom of the first flap 23, and a torsion spring that gives the movable part a downward rotation tendency is sleeved on the rotating shaft of the hinge. The fixed part of the hinge extends to form a limiting part that limits the downward rotation range of the movable part. In this way, the first flap 23 has less resistance to the mahjong tiles 10 and will not affect card loading and disrupt the mahjong tiles 10. Using the hinge form and torsion spring reset, the structure is simple and reliable, small in size, and low in cost.

[0138] For the four ramp card-loading mechanisms 6 distributed in a rectangle in the mahjong machine:

[0139] Such as Figure 20The four first card-on-ramps guides 63 in the four ramp card-on-ramps mechanisms 6 shown are joined end to end to form a quadrilateral, and the connection points of the head and tail of two adjacent first card-on-ramps guides 63 are arranged in a vertically offset manner; to maximize the use of space and create space for the second card-pushing head 74, facilitating the card pushing by the second card-pushing head 74.

[0140] As Figure 21 The four card-on-ramps chains 611 in the four ramp card-on-ramps mechanisms 6 shown are connected end to end to form a closed loop and are guided by at least two chain guide blocks 613 arranged diagonally. The chain guide blocks 613 are in smooth contact with the card-on-ramps chains 611, and the chain guide blocks 613 are fixed on the card-on-ramps support or the base plate 1.

[0141] As Figure 20 Among the two first guides 64 in two adjacent ramp card-on-ramps mechanisms 6 shown, one first guide 64 is located below the first arc guide 6312 of one first card-on-ramps guide 63, and the other first guide 64 is located below the second arc guide 6322 of the other first card-on-ramps guide 63. Such an arrangement is because the four first card-on-ramps guides 63 enclose a rounded rectangle and are arranged in a vertically offset manner, which results in an overlapping card-pushing trajectory of the four card-pushing heads during the ramp card-on-ramps process, that is, the movement trajectory of the initial section of one card-on-ramps card-pushing head 612 overlaps with the movement trajectory of the end section of the subsequent card-on-ramps card-pushing head 612 in the horizontal direction. However, one card-on-ramps card-pushing head 612 needs to push horizontally in the initial section and rise in the end section. Therefore, the adjacent first guides 64 should be located below the first arc guide 6312 and the second arc guide 6322 respectively to avoid overlapping card-pushing trajectories.

[0142] Specifically, a second card-on-ramps motor 68 is also provided. The second card-on-ramps motor 68 is located outside any one of the ramp card-on-ramps mechanisms 6 and is in transmission cooperation with the card-on-ramps chain 611.

[0143] The card-on-ramps process of the ramp card-on-ramps mechanism 6 is as follows: The second card-on-ramps motor 68 rotates forward to drive the card-on-ramps chain 611 to move, thereby driving the four card-on-ramps card-pushing heads 612 to move simultaneously. The card-on-ramps card-pushing heads 612 push the single-layer mahjong tiles 10 to advance along the width direction in the first card-on-ramps guide 63, and the first flap 23 is lifted by the mahjong tiles 10 during the rising process until the card-on-ramps card-pushing heads 612 push all the mahjong tiles 10 onto the mahjong machine table 2. Then, the second card-on-ramps motor 68 rotates in reverse to make the card-on-ramps card-pushing heads 612 return to their original positions, and the first flap 23 also returns to its original position under the action of the torsion spring, thus completing the card-on-ramps.

[0144] By using the ramp card-on-ramps mechanism 6 in this embodiment, the entire card-on-ramps process can be made smoother, so that the mahjong tiles 10 will not get stuck or jam due to too large a ramp slope.

[0145] It is worth noting that in this embodiment, the first card loading guide rail 63 in the slope card loading mechanism 6 extends to the second card pushing position 422 to form a second card receiving platform for storing mahjong tiles 10. Since the four card loading chains 611 are connected end to end and form a closed loop in the groove formed by the inner guide rail and the outer guide rail, and drive the card loading and pushing head 612 to move back and forth, the card loading and pushing head 612 and the second card pushing head 74 overlap in position and there is a wider groove in the middle of the second card receiving platform for allowing the mahjong tiles 10 to fall and jam the mahjong tiles 10. Therefore, the second card pushing head 74 is provided with a first avoidance groove. A fixed plate is provided at the second card receiving platform, and a movable plate is hinged at the lower end of the fixed plate by a hinge. A card receiving block 1 is provided at the upper end of the fixed plate, and a card receiving block 2 is provided at the upper end of the movable plate. The card receiving block 1 and the card receiving block 2 are combined to form a second card receiving platform that can be opened and closed. A chamfer is provided on one side of the card receiving block 1 and the card receiving block 2 close to the card pushing head 612. In this way, when the card pushing head 612 pushes the cards, it can avoid the second card pushing head 74 and open the movable plate along the chamfer to push the mahjong tiles 10. Its specific structure can refer to the Chinese patent document with publication number CN201949628U.

[0146] like Figure 23 The ramp card-entry mechanism 6 shown is a second implementation of the embodiment of the present application. The difference between this implementation and the ramp card-entry mechanism 6 in the first implementation is that:

[0147] The sloped card loading mechanism 6 includes a second card loading rail and a second flap 24, wherein the second flap 24 is located on the card exit of the mahjong machine table top 2, the second flap 24 is hinged to the mahjong machine table top 2, and the second flap 24 has two stop positions, flush with the mahjong machine table top 2 and docking with the second card loading rail. During the sloped card loading process, the second flap 24 falls and docks with the second card loading rail, and the card loading pusher 612 pushes the single-layer mahjong tile 10 along its length direction to the end of the second card loading rail, so that the last mahjong tile 10 is also pushed onto the second flap 24, and then the second flap 24 rises to be flush with the table top, and then the card loading pusher 612 returns to its original position to complete the card loading.

[0148] Specifically, the ramp card loading mechanism 6 also includes a card loading chain, the second card loading guide rail includes an inner guide rail and an outer guide rail distributed on both sides of the inner and outer sides of the bottom groove, the inner guide rail includes a third linear guide rail and a third arc guide rail arranged horizontally, and the outer guide rail includes a fourth linear guide rail and a fourth arc guide rail arranged horizontally; the card loading chain is located in the bottom groove between the inner guide rail and the outer guide rail and matches the card loading track of the mahjong tiles. Further preferably, the inner guide rail and the outer guide rail are integrally formed, which is convenient for installation and can improve the matching accuracy of the inner guide rail and the outer guide rail.

[0149] Specifically, a flap cam 66 and a flap ejector rod 67 are further provided. The flap cam 66 is in transmission connection with the first card-loading motor 52 in the flat-pushing card-loading device 5. One end of the flap ejector rod 67 is hinged to the lattice plate 51, and the other end of the flap ejector rod 67 is driven by the flap cam 66 to swing up and down and is connected to the second flap 24, so that the second flap 24 has two stopping positions, being flush with the mahjong table 2 and docking with the second card-loading guide rail. Such a setting not only has a reasonable spatial layout but also saves a card-lifting motor compared with the prior art.

[0150] For the ramp card-loading mechanism 6 that completes card loading through this implementation method, its card-loading driving mechanism can be diverse. For example, the card loading can be completed in the form of chain drive. The specific structure can refer to the Chinese patent document with the publication number CN208877886U or other similar chain drive structures. The card loading can also be completed in the form of wire rope drive. The specific structure can refer to the Chinese patent document with the publication number CN105413166A or other similar chain drive structures. The card loading can also be completed in the form of synchronous belt. The specific structure can refer to the Chinese patent document with the publication number CN208694237U or other similar synchronous belt drive structures.

[0151] It is worth noting that the second implementation method of the ramp card-loading mechanism 6 can adopt a variety of card-loading driving mechanisms because its card-loading driving mechanism only acts on the horizontal section during the card-loading process and the pushing trajectories of adjacent card-loading pushing heads 612 do not overlap.

[0152] The card-loading method of the above mahjong machine is as follows:

[0153] The mahjong tiles 10 on the shuffling tray 3 are sent to below the card-loading ports of the four card-sending devices 4 and are sucked up by the card-sucking wheels in the card-sending devices 4 and enter the card-sending channel 42 and are sorted out to be conveyed along its length direction. The card-sending devices 4 are sequentially provided with a first pushing position 421 and a second pushing position 422 along the direction of sending out the mahjong tiles 10. The pushing head 7 pushes the single mahjong tile 10 at the first pushing position 421 to the flat-pushing card-loading device 5, and the pushing head 7 pushes the single mahjong tile 10 at the second pushing position 422 to the ramp card-loading mechanism 6. When the flat-pushing card-loading device 5 and the ramp card-loading mechanism 6 store a sufficient number of mahjong tiles 10, the arranged mahjong tiles 10 are then conveyed to the mahjong table 2 through the flat-pushing card-loading device 5 and the ramp card-loading mechanism 6.

[0154] Specifically, four inner card - discharging ports 25 and four outer card - discharging ports 26 are provided on the mahjong machine table 2. The four inner card - discharging ports 25 are respectively located at the four sides of a rectangle, and the four outer card - discharging ports 26 are located outside the inner card - discharging ports 25 and are respectively close to the four corners of the rectangle. The flat - pushing card - loading device 5 sends two layers of mahjong tiles 10 to the mahjong machine table 2 through the four inner card - discharging ports 25, and the ramp card - loading mechanism 6 sends a single layer of tiles to the mahjong machine table 2 through the four outer card - discharging ports 26.

[0155] In the flat - pushing card - loading device 5, the first way of stacking tiles is as follows: It includes a tile - supporting plate 553 for storing two layers of mahjong tiles 10. A seesaw 56 is provided on the card - feeding port side of the tile - supporting plate 553. The seesaw 56 is flush with the tile - supporting plate 553 and is arranged with dislocation and avoidance. One end of the seesaw 56 close to the first tile - pushing position 421 can tilt upward. When the tile - supporting plate 553 receives the first layer of mahjong tiles 10, the movable end of the seesaw 56 tilts up and matches the height of the first tile - pushing position 421. The mahjong tiles 10 are pushed from the first tile - pushing position 421 along the seesaw 56 onto the tile - supporting plate 553. When the first layer of mahjong tiles 10 on the tile - supporting plate 553 is full, the movable end of the seesaw 56 drops, and then receives the second layer of mahjong tiles 10. At this time, the upper surface of the first layer of mahjong tiles 10 matches the height of the first tile - pushing position 421, and the tile - pushing head 7 continues to push the tiles until the second layer of mahjong tiles 10 is full.

[0156] The second way of stacking tiles is as follows: It includes a tile - supporting plate 553 for storing two layers of mahjong tiles 10. The tile - supporting plate 553 has two stopping positions that match the height of the first tile - pushing position 421 and are at least one mahjong - tile 10 thickness lower than the first tile - pushing position 421. When the tile - supporting plate 553 receives the first layer of mahjong tiles 10, the tile - supporting plate 553 matches the height of the first tile - pushing position 421, and the mahjong tiles 10 are conveyed to the tile - supporting plate 553 through the first tile - pushing position 421. When the first layer of mahjong tiles 10 on the tile - supporting plate 553 is full, the tile - supporting plate 553 descends, and the descending height is at least the thickness of one mahjong tile 10. The tile - pushing head 7 continues to push the tiles until the second layer of mahjong tiles 10 is full.

[0157] The first way of lifting tiles is as follows: When receiving a card - loading signal, which is often sent by a player, the tile - supporting plate 553 rises to a position flush with or higher than the mahjong machine table 2, and then the mahjong tiles 10 on the tile - supporting plate 553 are pushed out onto the mahjong machine table 2, and then the tile - supporting plate 553 descends to its original position to wait for the next round of tile stacking.

[0158] The second way of lifting tiles is as follows: When receiving a card - loading signal, which is often sent by a player, the cover plate on the inner card - discharging port 25 descends to a height matching the tile - supporting plate 553, and then the mahjong tiles 10 on the tile - supporting plate 553 are pushed out onto the cover plate, and then the cover plate rises to be flush with the mahjong machine table 2.

[0159] In the card-dealing mechanism 6 on the slope, the first card-dealing method is as follows: When receiving a card-dealing signal, which is usually sent by a player, the card-dealing pusher head 612 pushes the mahjong tiles 10 forward along the first card-dealing guide rail 63 and can lift the first flap 23 hinged to the mahjong table 2 at the out-card port 26 until all the mahjong tiles 10 are pushed onto the table. Then, the card-dealing pusher head 612 returns to its original position. After the card dealing is completed, the distribution of the mahjong tiles 10 is as shown in Figure 25 shown.

[0160] The second card-dealing method is as follows: When receiving a card-dealing signal, which is usually sent by a player, the second flap 24 hinged to the mahjong table 2 at the out-card port 26 drops and connects to the second card-dealing guide rail. The card-dealing head pushes the mahjong tiles 10 on the second card-dealing guide rail onto the second flap 24, and the second flap 24 flips up to be flush with the mahjong table 2. After the card dealing is completed, the distribution of the mahjong tiles 10 is as shown in Figure 26 shown.

[0161] It should be noted that in the description of this specification, "flush" and "height matching" between surface A and surface B both mean that the height difference between surface A and surface B is within 5 mm.

[0162] Embodiment 2:

[0163] The difference between this embodiment of the present application and Embodiment 1 lies in the structure of the card-pushing head, the card-pushing method, and the lifting method of the card-blocking block.

[0164] As shown in Figure 27 the card-pushing head includes a head box 71, a card-pushing motor 72, a first card-pushing head 73, a second card-pushing head 74, and a card-blocking block 75. The card-pushing motor 72 is installed on the head box 71; the first card-pushing head 73 is installed on the head box 71 and is driven by the card-pushing motor 72 to translate and slide relative to the head box 71; the second card-pushing head 74 is installed on the head box 71 and is driven by the card-pushing motor 72 to translate and slide relative to the head box 71; the card-blocking block 75 is installed on the head box 71 and is driven by the card-pushing motor 72 to move up and down relative to the head box 71; and a first card-pushing position 421 and a second card-pushing position 422 are arranged in the front-back direction along the conveying direction of the mahjong tiles 10. The card-blocking block 75 is arranged between the first card-pushing position 421 and the second card-pushing position 422 and can move up and down to block the mahjong tiles 10 and allow the mahjong tiles 10 to pass through. The first card-pushing head 73 is located on one side of the first card-pushing position 421 and translates and slides in and out of the first card-pushing position 421 to push the cards, and the second card-pushing head 74 is located on one side of the second card-pushing position 422 and translates and slides in and out of the second card-pushing position 422 to push the cards.

[0165] It should be noted that in this embodiment, the pushing card motor 72 is located on the side of the second pushing head 74. It is also possible to place the pushing card motor 72 on the side of the first pushing head 73 as in Embodiment 1. The specific structures of the first pushing head 73, the second pushing head 74, and the blocking card block 75 can refer to Embodiment 1.

[0166] As Figures 28 - 32 shown, a pushing head driving mechanism is further installed in the head box 71. The pushing head driving mechanism is used to control the first pushing head 73 and the second pushing head 74 to perform card pushing. Among them, the pushing card motor 72 rotates forward to drive the first pushing head 73 to perform card pushing, and the pushing card motor 72 rotates forward to drive the second pushing head 74 to perform card pushing. The pushing head driving mechanism includes a first pushing wheel 761 and a second pushing wheel 771 that are in transmission cooperation with the pushing card motor 72. The first pushing wheel 761 is in transmission connection with the first pushing head 73, and the second pushing wheel 771 is in transmission connection with the second pushing head 74. The pushing card motor 72 drives the first pushing wheel 761 to rotate, thereby enabling the first pushing head 73 to perform card pushing; the pushing card motor 72 drives the second pushing wheel 771 to rotate, thereby enabling the second pushing head 74 to perform card pushing; further preferably, it further includes a camshaft 792 that is in transmission cooperation with the pushing card motor 72, and a one-way bearing A791 sleeved on the camshaft 792. The first pushing wheel 761 is in transmission cooperation with the outer surface of the one-way bearing A791. The second lifting wheel 772 is fixedly or movably installed on the camshaft 792. The pushing card motor 72 rotates forward to drive the first pushing wheel 761 to rotate, thereby enabling the first pushing head 73 to perform card pushing, that is, the first pushing head 73 translates and slides in and out of the first card pushing position 421 to achieve card pushing. At this time, the second pushing head 74 can either push the card empty or remain stationary; the pushing card motor 72 rotates in reverse to drive the second pushing wheel 771 to rotate, thereby enabling the second pushing head 74 to perform card pushing, that is, the second pushing head 74 translates and slides in and out of the second card pushing position 422 to achieve card pushing. At this time, the first pushing head 73 remains stationary.

[0167] When the second pushing wheel 771 is fixedly installed on the camshaft 792, the pushing card motor 72 drives the camshaft 792 to rotate forward, the first pushing head 73 performs card pushing, the second pushing wheel 771 rotates forward, and the second pushing head 74 pushes the card empty. When the pushing card motor 72 drives the camshaft 792 to rotate in reverse, the first pushing head 73 remains stationary, the second pushing wheel 771 rotates in reverse, and the second pushing head 74 performs card pushing.

[0168] When the second card pushing wheel 771 is movably installed on the camshaft 792, a one-way bearing B793 is also sleeved on the camshaft 792. The outer surface of the one-way bearing B793 is in transmission cooperation with the second card pushing wheel 771. When the card pushing motor 72 drives the camshaft 792 to rotate forward, the first card pushing head 73 performs card pushing, and the second card pushing wheel 771 and the second card pushing head 74 are stationary. When the card pushing motor 72 drives the camshaft 792 to rotate reversely, the first card pushing head 73 is stationary, the second card pushing wheel 771 rotates reversely and the second card pushing head 74 performs card pushing.

[0169] Specifically, a first swing arm 794 and a second swing arm 795 are further arranged in the machine head box 71. The lower ends of the first swing arm 794 and the second swing arm 795 are hinged to the machine head box 71. The lower part of the first swing arm 794 is movably matched with the first card pushing wheel 761, the lower part of the second swing arm 795 is movably matched with the second card pushing wheel 771, the upper part of the first swing arm 794 is movably matched with the first card pushing head 73, and the upper part of the second swing arm 795 is movably matched with the second card pushing head 74. When the card pushing motor 72 drives the first card pushing wheel 761 to rotate forward, the first swing arm 794 is driven to swing, thereby pushing the first card pushing head 73 to perform card pushing. At this time, the second card pushing wheel 771 can rotate forward or remain stationary. When the card pushing motor 72 drives the second card pushing wheel 771 to rotate reversely, the second swing arm 795 is driven to swing, thereby pushing the second card pushing head 74 to perform card pushing. At this time, the first card pushing wheel 761 is stationary; further preferably, the specific structure of the lower part of the first swing arm 794 movably matched with the first card pushing wheel 761 can refer to the specific structure of the first connecting block 70 movably matched with the first curve wheel 76 in Embodiment 1. The specific structure of the upper part of the first swing arm 794 movably matched with the first card pushing head 73 can refer to the specific structure of the first connecting block 70 movably matched with the first card pushing head 73 in Embodiment 1, that is, the rotation of the first card pushing wheel 761 is converted into the swinging action of the first swing arm 794 through a rolling bearing, and then the swinging of the first swing arm 794 is converted into the card pushing action of the first card pushing head 73. By setting a tension spring or arranging a first contact surface and a second contact surface matched with the rolling bearing before and after the card pushing direction, when the first card pushing wheel 761 no longer applies a forward pushing force to the first swing arm 794, the first swing arm 794 returns to its original position; and the specific structure of the upper part of the second swing arm 795 movably matched with the second card pushing head 74 can refer to the specific structure of the first connecting block 70 movably matched with the second card pushing head 74 in Embodiment 1, that is, the swinging of the second swing arm 795 is converted into the card pushing action of the second card pushing head 74 through a rolling bearing, and by setting a tension spring or arranging a first contact surface and a second contact surface matched with the rolling bearing before and after the card pushing direction, when the second card pushing wheel 771 no longer applies a forward pushing force to the second swing arm 795, the second swing arm 795 returns to its original position.

[0170] With such a setting, the pushing motor 72 rotates forward to complete the pushing action of the first pushing head 73, and rotates reversely to complete the pushing action of the second pushing head 74. During a complete card loading process, the pushing motor 72 has only one forward and reverse switching. Compared with the forward and reverse switching of the pushing motor 72 for each pushed mahjong tile 10 in Embodiment 1, the pushing head in this embodiment is more in line with the working characteristics of the pushing motor 72 and can significantly improve the working life of the pushing motor 72.

[0171] As Figures 28 - 32 In the head box 71 shown, a lifting mechanism for the blocking block 75 is also installed. The lifting mechanism for the blocking block 75 is used to control whether the blocking block 75 is located between the first pushing position 421 and the second pushing position 422. The forward rotation of the pushing motor causes the blocking block to be located between the first pushing position (421) and the second pushing position (422), and the reverse rotation of the pushing motor causes the blocking block not to be located between the first pushing position (421) and the second pushing position (422).

[0172] The lifting mechanism for the blocking block 75 includes a first lifting wheel 762 and a second lifting wheel 772 that are in transmission cooperation with the pushing motor 72. The first lifting wheel 762 and the second lifting wheel 772 are respectively in transmission connection with the blocking block 75. The pushing motor 72 drives the first lifting wheel 762 to rotate, so that the blocking block 75 has a low-position staying position; the pushing motor 72 drives the second lifting wheel 772 to rotate, so that the blocking block 75 has a high-position staying position; further preferably, it also includes a camshaft 792 in transmission cooperation with the pushing motor 72, and a one-way bearing A791 and a one-way bearing B793 sleeved on the camshaft 792. The first lifting wheel 762 is in transmission cooperation with the outer surface of the one-way bearing A791, and the second lifting wheel 772 is in transmission cooperation with the outer surface of the one-way bearing B793. The forward rotation of the pushing motor 72 drives the first lifting wheel 762 to rotate, so that the blocking block 75 has a low-position staying position, that is, the blocking block 75 is located between the first pushing position 421 and the second pushing position 422; the reverse rotation of the pushing motor 72 drives the second lifting wheel 772 to rotate, so that the blocking block 75 has a high-position staying position, that is, the blocking block 75 is not located between the first pushing position 421 and the second pushing position 422.

[0173] Specifically, a rotating block 796 and a baffle spring piece 797 are also provided in the head box 71, and the baffle spring piece 797 is installed in the head box 71. A lifting block 753 is provided on the lower surface of the baffle block 75, and the baffle spring piece 797 at one end of the rotating block 796 is movably cooperated, and the other end is hinged to the lifting block 753; a second baffle shift block 7962 is provided on the front side of the rotating block 796 and a first baffle shift block 7961 is provided on the rear side, the first baffle shift block 7961 and the second baffle shift block 7962 are fixedly connected or integrally formed with the rotating block 796, the first baffle shift block 7961 is movably cooperated with the first lifting wheel 762, and the second baffle shift block 7962 is movably cooperated with the second lifting wheel 772, and the card pushing motor 72 drives the first lifting wheel 762 to rotate forward, thereby driving the rotating block 796 to rotate, and bringing The movable lifting block 753 descends and makes the card blocking block 75 have a low stop position, that is, it is located between the first card pushing position 421 and the second card pushing position 422; the card pushing motor 72 drives the second lifting wheel 772 to reverse, thereby driving the rotating block 796 to rotate, and drives the lifting block 753 to descend and makes the card blocking block 75 have a high stop position, that is, it is no longer located between the first card pushing position 421 and the second card pushing position 422; further preferably, the rotating block 796 is provided with a first stop surface 7963 and a second stop surface 7964 that cooperate with the baffle spring sheet 797, and there is a certain inclined angle between the first stop surface 7963 and the second stop surface 7964, and the driving motor drives the first lifting wheel 762 to rotate forward to drive the rotating block 796 from the second stop surface 7964 to abut against the baffle spring sheet 797 The driving motor drives the second lifting wheel 772 to reverse and drive the rotating block 796 to rotate from the first stop surface 7963 against the baffle spring sheet 797 to the second stop surface 7964 against the baffle spring sheet 797, so that the baffle block 75 has a low stop position.

[0174] More preferably, the lifting block 753 is provided with a second connecting shaft 7531, the second connecting shaft 7531 is fixedly connected to or integrally formed with the lifting block 753, and the rotating block 796 is provided with a long hole, which can be a complete hole or a hole with a notch. In the present embodiment, the long hole has a notch, and the second connecting shaft 7531 is movably matched with the long hole. Such an arrangement allows the lifting block 753 to be lifted and lowered in situ driven by the rotating block 796.

[0175] Specifically, the first lifting wheel 762 and the second lifting wheel 772 are circumferentially distributed in different regions on the camshaft 792. This is set because the first baffle block 7961 and the second baffle block 7962 are respectively located on the front and rear sides of the rotating block 796 and rotate together. When the first lifting wheel 762 rotates forward to drive the first card-blocking piece to rotate forward to drive the lifting block 753 to descend, if the circumferentially distributed regions of the first lifting wheel 762 and the second lifting wheel 772 on the camshaft 792 overlap, it will hinder the rotation of the second card-blocking piece; and when the second lifting wheel 772 rotates reversely to drive the second card-blocking piece to rotate reversely to drive the lifting block 753 to ascend, if the circumferentially distributed regions of the first lifting wheel 762 and the second lifting wheel 772 on the camshaft 792 overlap, it will hinder the rotation of the first card-blocking piece.

[0176] As Figure 33 and 34 A first camshaft sleeve 712 is also fixed in the machine head box 71 as shown. The camshaft 792 can rotate in the first camshaft sleeve 712. A one-way bearing C798 is sleeved at the rear end of the first camshaft sleeve 712. The outer surface of the one-way bearing C798 is in transmission connection with the first card-pushing wheel 761 and the first lifting wheel 762. The one-way bearing C798 is used to limit the reverse rotation of the first card-pushing wheel 761 and the first lifting wheel 762.

[0177] Specifically, a second camshaft sleeve 713 is also fixed in the head box 71, and the camshaft 792 can rotate in the second camshaft sleeve 713. A one-way bearing D799 is sleeved on the front end of the second camshaft sleeve 713. The outer surface of the one-way bearing D799 is transmission-connected with at least the second lifting wheel 772 of the second card-pushing wheel 771 and the second lifting wheel 772. The one-way bearing D799 is used to limit the forward rotation of at least the second lifting wheel 772 of the second card-pushing wheel 771 and the second lifting wheel 772. This is set up because the card-pushing motor 72 drives the camshaft 792 to rotate forward for one circle, and the first card-pushing head 73 completes a reciprocating linear motion of pushing cards. The first card pushing wheel 761 and the first lifting wheel 762 are only matched with the camshaft 792 through a single one-way bearing A791. Then, when the camshaft 792 stops rotating, the first card pushing wheel 761 and the first lifting wheel 762 will swing back due to inertia, which may affect the first card pushing head 73 from completely returning to its original position, thereby causing a card failure and the blocking block 75 to stay in the wrong position. After the one-way bearing C798 is matched, the one-way bearing C798 does not affect the forward rotation of the first card pushing wheel 761 and the first lifting wheel 762, but can prevent the first card pushing wheel 761 and the first lifting wheel 762 from swinging back; similarly, the one-way bearing D799 is also used to at least prevent the second lifting wheel 772 of the second card pushing wheel 771 and the second lifting wheel 772 from swinging back.

[0178] More preferably, the first camshaft sleeve 712 and the second camshaft sleeve 713 may be integrally formed or may be two separate parts.

[0179] Specifically, the head box 71 is also provided with a first card-viewing light control 714 and a second card-viewing light control 715, and the first card-viewing light control 714 and the second card-viewing light control 715 are respectively located at the rear side and the front side of the first card blocking part 751; further preferably, the first card-viewing light control 714 is located below the first card pushing head 73, and the second card-viewing light control 715 is located below the second card pushing head 74.

[0180] Specifically, the head box 71 is further provided with a baffle sensor 716 , and the baffle sensor 716 is used to detect the movement of the baffle block 75 into and out of the first card pushing position 421 and the second card pushing position 422 .

[0181] It is worth noting that the baffle sensor 716, the first card viewing light control 714 and the second card viewing light control 715 can also be applied to the card pushing machine head in Example 1.

[0182] A first curve wheel 76 includes the first card pushing wheel 761 and the first lifting wheel 762 as described above. The first lifting wheel 762 and the first card pushing wheel 761 can be fixedly connected, integrally formed, or two separate parts.

[0183] A second curve wheel 77 includes the second card pushing wheel 771 and the second lifting wheel 772 as described above. The second lifting wheel 772 and the second card pushing wheel 771 can be fixedly connected, integrally formed, or two separate parts.

[0184] In this embodiment, the card pushing process of the card pushing machine head is as follows:

[0185] like Figure 28 As shown, when the card-pushing device is feeding cards, the initial position of the card-blocking block 75 is at a low position, that is, the first card-blocking portion 751 is located between the first card-pushing position 421 and the second card-pushing position 422. When the card-feeding device delivers the mahjong tile 10 to the first card-pushing position 421, the mahjong tile 10 is blocked by the first card-blocking portion 751, and the first card-viewing light control 714 located on the head box 71 senses the mahjong tile 10. Figure 29 As shown, the card pushing motor 72 rotates forward to drive the first curved wheel 76 to rotate forward, driving the first swing arm 794 to swing and causing the first card pushing head 73 to push the cards. The first card pushing head 73 pushes the single mahjong tile 10 from the first card pushing position 421 into the horizontal pushing card loading device. After the card pushing motor 72 rotates forward for one circle, the first card pushing head 73 returns to its original position, waiting for the next card pushing, and repeats this action until the horizontal pushing card loading device is full of mahjong tiles 10. During the card pushing process, since the baffle block 75 is in a low position, the first curved wheel 76 does not generate thrust on the first baffle plate block 7961 during rotation, and when the second card pushing wheel 771 in the second curved wheel 77 is fixed on the camshaft 792, the second card pushing head 74 pushes empty, and when the second card pushing wheel 771 is movably connected to the camshaft 792 through the one-way bearing B793, the second card pushing head 74 is stationary.

[0186] After the push card loading device is fully loaded, Figures 30 - 32 As shown, the card pushing motor 72 reverses to drive the second curve wheel 77 to rotate and then drives the second baffle block 7962 to rotate, so that the first stop surface 7963 on the rotating block 796 is converted from abutting against the baffle spring sheet 797 to a second stop surface 7964 abutting against the baffle spring sheet 797 and drives the lifting block 753 to rise, thereby making the card blocking block 75 move out between the first card pushing position 421 and the second card pushing position 422. During this process, the first card pushing head 73 is stationary and the second card pushing head 74 is pushed in vain.

[0187] After the card delivery device delivers the mahjong tile 10 to the second card pushing position 422, the second card viewing light control 715 senses that the mahjong tile 10 is in place. Figures 30 - 32As shown, the card pushing motor 72 reverses to drive the second curved wheel 77 to rotate, thereby driving the second swing arm 795 to swing and causing the second card pushing head 74 to push the cards. The second card pushing head 74 pushes the single mahjong tile 10 from the second card pushing position 422 into the slope card loading mechanism. After the card pushing motor 72 reverses one circle, the second card pushing head 74 returns to its original position, waiting for the next card pushing, and repeats this action until the slope card loading mechanism is full of mahjong tiles 10; in the card pushing process, since the baffle block 75 is in a high position, the second curved wheel 77 does not generate thrust on the second baffle block 7962 during rotation, and the first card pushing head 73 is stationary.

[0188] After the ramp loading mechanism is fully loaded, Figure 29 and Figure 30 As shown, the card pushing motor 72 drives the first curve wheel 76 to rotate in the forward direction and then drives the first baffle block 7961 to rotate, so that the second stop surface 7964 on the rotating block 796 is converted from abutting against the baffle spring sheet 797 to abutting against the baffle spring sheet 797 with the first stop surface 7963 and driving the lifting block 753 to descend, thereby making the card blocking block 75 move between the first card pushing position 421 and the second card pushing position 422 to wait for the next card loading.

[0189] It is worth mentioning that the card pushing head described in Example 2 can also include two card pushing motors 72 like the card pushing head in Example 1, wherein one card pushing motor 72 is used to drive the first curve wheel 76 to rotate so that the first card pushing head 73 can push the cards and the card blocking block 75 has a low stop position, and the other card pushing motor 72 is used to drive the second curve wheel 77 to rotate so that the second card pushing head 74 can push the cards and the card blocking block 75 has a high stop position.

[0190] A card picking and transporting system comprises the card pushing machine head described in Example 2.

[0191] A mahjong machine comprises the card pushing machine head described in embodiment 2.
