Description

Technical Field

[0001] The invention relates to the technical field of mahjong machine manufacturing, in particular to a mahjong machine and a card pushing machine head and a card pushing head driving mechanism thereof. Background Art

[0002] The current fully automatic mahjong machine can integrate functions such as shuffling and dice rolling, which provides a lot of convenience for people to play mahjong. However, the current fully automatic mahjong machine basically only has four outlets, and then the mahjong is transported from the four outlets to the mahjong table. When playing mahjong, it is still necessary to push the cards, cut the cards, and arrange the cards manually, which is not only troublesome to operate, but also may cause the wrong cutting of the cards, and can only be reshuffled.

[0003] In order to solve this problem, the Chinese invention patent with patent number CN200920118048.7 discloses an automatic mahjong machine, including a mahjong machine table and a host arranged below the mahjong machine table, the host is provided with an inner lattice plate, the outer side of the inner lattice plate is provided with an outer lattice plate, the four outer lattice plates are connected by four arc-shaped transition sections to form a circular track for carrying mahjong tiles, a circular pushing device for pushing mahjong tiles is provided above the circular track, a slide rail is provided below the pusher head, the pusher head is driven by a motor to slide between the inner push port and the outer push port, and a seesaw device for guiding the mahjong tiles on the circular track to the mahjong machine table is provided on the mahjong machine table just above the four outer lattice plates. The automatic mahjong machine provided by the present invention has thirteen tiles to be grabbed by the game participants on each of the four outer side tiles, so that the game participants can obtain a more convenient, fast and comfortable game experience.

[0004] The principle of the card raising of the automatic mahjong machine is as follows: the card pusher of the card pusher is at the outer card pusher mouth at the beginning, pushing cards to the outer layer of the lattice board. When 13 cards are pushed, the control system sends a command, and the card pusher drives the card pusher to move to the inner card pusher mouth, and the card pusher starts to push cards. When the card pusher pushes a certain number of piles (depending on the total number of piles in the game), the motor of the flat push assembly rotates, drives the guide plate to fall, and then pushes the second layer of cards. When the four outer lattice boards are full of 13 cards, and the card pusher heads are all moved to the inner card pusher mouth, the control system sends a signal, the wire rope motor starts to rotate, drives the cards to move on the circular track, and then walks to the position waiting for the cards to be loaded. When one inner lattice board is stacked with cards, the conveying motor reverses, and the remaining cards in the conveying device are returned to the large plate, and sent to the card loading ports of other conveying devices, until the last four inner lattice boards are stacked with cards.

[0005] The shortcomings of this automatic mahjong machine are:

[0006] 1) There are an outer push-card port and an inner push-card port in the conveying channel. The mahjong first passes through the inner push-card port and then the outer push-card port. Therefore, when the push-card head is at the inner push-card port, the mahjong may be missed and reach the outer push-card port, causing the mahjong machine to jam;

[0007] 2) Another driving device such as a motor is required to move the card pusher from the outer card push port to the inner card push port and from the inner card push port to the outer card push port, which is costly.

[0008] The patent application document with publication number CN107519637A discloses a mahjong machine and a card loading method thereof. The mahjong machine includes four groups of card picking and transporting systems arranged around a shuffling plate. The card picking and transporting systems include a card feeding device for picking up mahjong tiles one by one from the shuffling plate and delivering them, a card stacking device for stacking two mahjong tiles into one pile, a card pushing device for pushing mahjong tiles into a card storage slot, and a ramp card discharging device for delivering the arranged mahjong tiles in multiple piles onto the mahjong machine table along a slope. The ramp card discharging device includes a card loading component and a card raising component. The card loading component includes a card storage slot, and the card storage slot is curved in a large-angle arc shape, thereby increasing the storage quantity of mahjong tiles in the card storage slot. The card loading component and the card raising component in the same group of card picking and transporting systems are directly adjacent to each other. The above-mentioned mahjong machine can implement a method of loading mahjong tiles in stages. When storing mahjong tiles, the card feeding device picks up the mahjong tiles and pushes them into the card storage slot by the card pushing device; when the mahjong machine receives the first loading signal, the card lifting plate of the card lifting device descends, and the card loading and pushing head first pushes a part of the mahjong tiles in the card storage slot (generally six and a half tricks or thirteen mahjong tiles) onto the card lifting plate, and the card lifting plate rises to load these mahjong tiles onto the tabletop, waiting for the player to take the mahjong tiles on the tabletop; after the mahjong machine receives the second loading signal, the card lifting plate descends here, and the card loading and pushing head pushes the remaining mahjong tiles in the card storage slot onto the card lifting plate, and the card lifting plate rises to load the mahjong tiles onto the tabletop. By adopting this scheme of loading cards and pushing them twice in stages, the function of an eight-mouth mahjong machine can be realized using the existing four-mouth mahjong machine structure. However, since the card loading and pushing head occupies the position of one pile of cards in the card storage slot during the process of loading cards to the card raising device, a card storage slot length of 18-19 piles of cards is required for 17 piles of cards. When using a mahjong machine in this way to play larger cards, the required track length of the mahjong machine is longer, which cannot be achieved by mahjong machines of existing machine sizes. Therefore, it is necessary to minimize the length of the mahjong machine card storage slot.

[0009] The utility model patent with publication number CN108635827A discloses a card loading structure of a three-layer mahjong machine, comprising an annular single-layer card track and an annular double-layer card track which are overlapped and installed up and down, the single-layer card track is installed with a motor seat, the motor seat is installed with a second motor through a gear, the motor seat is installed with a first motor through a rotating shaft, the passive shaft on the motor seat 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 lever is arranged on the single-layer card turntable, and a card adjustment circle and a double-layer card lever placed in the card adjustment circle are installed on the double-layer card track; after three-layer cards enter the card track, the second motor drives the gear to drive the single-layer card turntable to rotate, and the cards of the single-layer card track are pushed to the mahjong machine table through the single-layer card lever of the single-layer card turntable; after three-layer cards enter the card track, the first motor drives the rotating shaft to drive the double-layer card lever to rotate, and the cards of the double-layer card track are pushed to the mahjong machine table. The mahjong machine of the above structure stacks three mahjong tiles into one pile, divides one pile of mahjong tiles into a single layer (one tile) and a double layer (two tiles stacked), respectively feeds them into the single-layer tile track and the double-layer tile track, and then feeds them to the mahjong machine table. This arrangement can effectively shorten the required mahjong machine track length, but the card loading structure of the above mahjong machine occupies a large height, and the overall height of the mahjong machine using this structure is large, especially when playing larger mahjong tiles, which cannot be achieved by mahjong machines of existing machine sizes. In addition, when one pile of mahjong tiles is divided into a single layer (one tile) and a double layer (two tiles stacked), respectively feeds them into the single-layer tile track and the double-layer tile track, the precision required for the track boundary is extremely high, and a slight deviation will cause the mahjong machine to jam. On the other hand, two motors are used to directly or indirectly drive two card pushers to push the mahjong tiles in the single-layer tile track and the double-layer tile track, which increases the structural complexity and control complexity of the mahjong machine and increases the production cost of the mahjong machine.

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.

[0067] 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.

[0068] 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.

[0069] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0070] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

[0071] In the present invention, the center of the mahjong machine is regarded as the inside, and the periphery of the mahjong machine is regarded as the outside.

[0072] In the present invention, the forward rotation and reverse rotation of a single motor only represent that the rotation direction of the single motor itself is opposite, that is, when one motor rotates forward and the other motor rotates reversely, the rotation directions of the two motors may be the same or different.

[0073] Embodiment 1:

[0074] like Figure 1-3 A mahjong machine shown in the figure comprises a bottom plate 1, a mahjong machine table top 2, a shuffling tray 3 and its driving mechanism located in the center, and four sets of card picking and transporting systems surrounding the shuffling tray 3. The card picking and transporting system comprises a card feeding device 4 for picking up mahjong tiles 10 from the shuffling tray 3 one by one and delivering them, a flat-push card loading device 5 and a slope card loading mechanism 6 for delivering the arranged mahjong tiles 10 onto the mahjong machine table top 2, and a card pushing machine head 7 for pushing the mahjong tiles 10 to the flat-push card loading device 5 and the slope card loading mechanism 6 respectively, wherein the four flat-push card loading devices 5 are surrounded by a rectangular shape parallel to the edge of the table top, and the four slope card loading mechanisms 6 are surrounded by a rectangular shape parallel to the edge of the table top, and the slope card loading mechanism 6 is located outside the flat-push card loading device 5.

[0075] The card pushing machine head 7 can push a single mahjong tile 10 onto the flat-push card loading device 5 until the first layer of mahjong tiles 10 of the flat-push card loading device 5 is full, and then the card pushing machine head 7 pushes the second layer of mahjong tiles 10 onto the first layer of mahjong tiles 10, and then the flat-push card loading device 5 pushes the tiles out and raises them to the mahjong machine tabletop 2.

[0076] The pusher head 7 can also push a single mahjong tile 10 to move on the sloped card loading mechanism 6 until a specified number of tiles is reached, and then the sloped card loading mechanism 6 pushes the tile out and raises it to the mahjong machine tabletop 2.

[0077] In this way, the entire mahjong machine always transports a single layer of mahjong tiles 10 during the process of transporting the mahjong tiles 10, which can significantly shorten the vertical distance from the mahjong tiles 10 to the table top 2 of the mahjong machine, that is, for the sloped card loading mechanism 6, the slope gradient is significantly reduced, thereby making the card loading process smoother and more stable, and for the card pushing machine head 7, it is no longer necessary to stack the mahjong tiles 10, so that the card pushing mechanism structure is simple, and the problem of mahjong tiles 10 being easy to flip over when stacking is avoided. For the entire mahjong machine, the four sets of card picking and transporting systems can be arranged more compactly, thereby reducing the volume of the entire mahjong machine.

[0078] like Figure 4-5 The mahjong table top 2 shown in the figure is provided with four inner card outlets 25 and four outer card outlets 26, the four inner card outlets 25 are rectangular and parallel to the edge of the mahjong table top 2, the four outer card outlets 26 are located outside the inner card outlets 25, and the four outer card outlets 26 are respectively located at the four corners of the mahjong table top 2 or near the four corners, the flat push card loading device 5 delivers two layers of mahjong tiles 10 to the mahjong table top 2 through the four inner card outlets 25, and the slope card loading mechanism 6 delivers single-layer tiles to the mahjong table top 2 through the four outer card outlets 26.

[0079] In the embodiment of the present application, the distribution of the four inner card outlets 25 is different from that of the existing similar four-mouth mahjong machine in the following ways: the card loading of the four-mouth mahjong machine is to transport all the mahjong tiles 10 to the mahjong machine table 2 through the four card outlets. Therefore, the card outlets of the four-mouth mahjong machine need to accommodate the complete number of mahjong tiles 10. Moreover, the stacking and pushing components of the head of the four-mouth machine are now integrated with the flat pushing components, which relatively takes up more space, resulting in the minimum length of the card support plate being not less than 540mm. In the eight-mouth mahjong machine in the embodiment of the present application, the inner card outlets 25 only need to accommodate the remaining number of mahjong tiles 10 after the player grabs 12-13 cards.

The mahjong tiles 10 are uniformly literal-side down after the rotation of the card feeding wheel, and uniformly fed in the length direction of the mahjong tiles 10 after passing through the straight card guide groove.

[0098] The running path of the mahjong tiles 10 in the card feeding device 4 is the card feeding channel 42, which starts from the card inlet of the card feeding box 41 and ends at the card outlet of the card feeding box 41. The card feeding channel 42 is a linear channel, and the card outlet of the card feeding channel 42 is connected to the slope card loading mechanism 6. When the mahjong tiles 10 are transported to the card outlet of the card feeding channel 42, they are transported to the slope card loading mechanism 6 through the card outlet wheel; the first card pushing position 421 and the second card pushing position 422 are sequentially arranged outside the card outlet of the card feeding channel 42 along the direction in which the mahjong tiles 10 are sent out, and the card inlet of the horizontal push card loading 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 sloped card loading mechanism 6 and the second card pushing head 74 are respectively located on opposite sides of the second card pushing position 422; when the card blocking block 75 moves between the first card pushing position 421 and the second card pushing position 422, the card 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-push card loading device 5; when the card blocking block 75 moves out from 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 sloped card loading mechanism 6.

[0100] At least two in-place detection devices are also provided, one of which is located on the first card pushing head 73 , and the other is located in the slope card loading mechanism 6 .

[0101] The specific process of a card pushing motor 72 coaxially driving the first curve wheel 76 and the second curve wheel 77 and making the mahjong tiles 10 enter the flat push card loading device 5 and the slope card loading mechanism 6 respectively is as follows:

[0102] like Fig.15 As shown, when the card-pushing device 5 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 4 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 in-position detection device located on the first card-pushing head 73 senses the mahjong tile 10. Fig.16The card pushing motor 72 shown in the figure drives the first curve wheel 76 and the second curve wheel 77 to rotate forward, wherein the first curve wheel 76 follows a concentric circle curve and the second curve wheel 77 follows an ascending curve, driving the first connecting block 70 to rotate around the first connecting shaft 711 and causing the first card pushing head 73 and the second card pushing head 74 to push forward. At this time, the first card blocking portion 751 is still located between the first card pushing position 421 and the second card pushing position 422, that is, the gap between the first card blocking portion 751 and the card feeding track is smaller than the height of the mahjong tile 10, and the second card blocking portion 752 is located below the card inlet of the horizontal push card loading device 5, and the first card pushing head 73 pushes a single mahjong tile 10 from the first card pushing position 421 into the horizontal push card loading device 5, and the second card pushing head 74 pushes empty, and then the card pushing motor 72 is reversed, and the first card pushing head 73 and the second card pushing head 74 return to their original positions, waiting for pushing cards, and repeating this action until the number of mahjong tiles 10 in the horizontal push card loading device 5 reaches the specified number;

[0103] After the flat push card loading device 5 is fully loaded, Fig.17 As shown, the card pushing motor 72 reverses and drives the first curve wheel 76 and the second curve wheel 77 to rotate, wherein the first curve wheel 76 follows an ascending curve, and the second curve wheel 77 follows a concentric circle curve, driving the card blocking block 75, the first mounting seat 78 and the first card pushing head 73 to rise, that is, the gap between the first card blocking portion 751 and the card feeding track is greater than the height of the mahjong tile 10, 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 to prevent the mahjong tile 10 from entering the card inlet of the horizontal push card loading device 5, and the mahjong tile 10 enters the second card pushing position 422. In addition, at this time, due to the rise of the first card pushing head 73, the third connecting block 731 at its bottom is no longer in contact with the sixth rolling bearing 702, or the third connecting block 731 and the eighth connecting block are no longer in contact with the sixth rolling bearing 702.

[0104] like Fig.18 As shown, the card pushing motor 72 continues to reverse and drive the first curve wheel 76 and the second curve wheel 77 to rotate, wherein the first curve wheel 76 follows a concentric circle curve and the second curve wheel 77 follows an ascending curve, driving the first connecting block 70 to rotate around the first connecting shaft 711 and pushing the second card pushing head 74 forward. At this time, the card blocking block 75 has moved out from between the first card pushing position 421 and the second card pushing position 422, that is, a single mahjong tile 10 has entered the second card pushing position 422 and is then pushed by the second card pushing head 74, the first card pushing head 73 is stationary, and then the card pushing motor 72 rotates forward, the first card pushing head 73 and the second card pushing head 74 return to their original positions, and this action is repeated until the number of mahjong tiles 10 in the ramp loading mechanism 6 reaches the specified number.

[0105] When there are two card pushing motors 72 in the card pushing machine head 7, the card pushing process is as follows:

[0106] 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;

[0107] 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;

[0108] 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;

[0109] 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.

[0110] like Figure 6-13 The flat push card loading device 5 shown is the first embodiment of the present application, which adopts the method of first lifting the card and then pushing the card to complete the card loading. In this embodiment, the flat push card loading device 5 includes a grid plate 51, and a first card loading motor 52 installed on the grid plate 51, a card holding plate 553, a card pushing mechanism and a lifting mechanism. The card holding plate 553 is connected to the grid 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 The card supporting plate 553 is driven to rise and fall by the lifting mechanism. 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; a seesaw 56 is also provided on the lattice plate 51. The seesaw 56 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 to rise or fall by the first card loading motor 52.

[0111] 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.

[0112] Specifically, the first card-loading motor 52 is 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 push-pull gear 533 and a right lifting gear 534 which are installed on the lattice plate 51 and mesh with each other in sequence, and the driving gear 532 is connected to the output shaft of the first card-loading motor 52; the lifting mechanism includes two lifting cranks 554, and 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 supported by the bottom cam curve of the support frame 555, and 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 device The main shaft 542, two card pushing rockers 543, a card pushing plate 544 and a first connecting member 545, a card pushing cam 541 is fixedly connected to the push-pull gear 533, one end of the first connecting member 545 is in transmission 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 mounted 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, and 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 horizontal pushing slider, the horizontal pushing slider is slidably connected to the card pushing bracket 546, the horizontal pushing slider is driven to translate by the card pushing rocker 543, and the card pushing bracket 546 is fixedly connected to the card supporting plate 553 and rises and falls synchronously.

[0113] It is worth noting that, in order to ensure a 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.

[0114] Specifically, a seesaw cam 57 and a seesaw gear 56 coaxially fixed to the seesaw cam 57 are installed on the lattice plate 51 , and the seesaw gear 56 cooperates with the left lifting gear 531 or the right lifting gear 534 for transmission.

[0115] It is worth mentioning that the rocker cam 57 can also be installed on the lifting crank 554 and be integrally formed with the lifting crank 554. The lower surface of the rocker 56 is provided with a first protrusion 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 protrusion, the rocker 56 can still have two staying positions: tilted upward and laid flat.

[0116] Specifically, the left lifting gear 531 or the right lifting gear 534 has double-layer teeth, one layer of teeth is complete teeth and meshes with the driving gear 532 or the push-pull gear 533 for transmission, and the other layer of gears is incomplete teeth and meshes with the seesaw 56 gear for transmission.

[0117] Specifically, the card pushing bracket 546 is installed under the card supporting plate 553, and two sliding rods 547 are fixed on the card pushing bracket 546. The horizontal pushing slider slides on the sliding rods 547 and is reset by a spring. The horizontal pushing slider has two extension parts 5481 extending upward, and the card pushing plate 544 is installed on the two extension parts 5481. The tops of the two card pushing rockers 543 are both provided with third rolling bearings 5431. When the card pushing bracket 546 and the card supporting plate 553 are raised, the two third rolling bearings 5431 are respectively in contact with the two sides of the horizontal pushing slider.

[0118] like Figure 7 and Figure 8 As shown, the stacking process of the present embodiment 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, so that the first card pushing head 73 can push the mahjong tiles 10 onto the card supporting plate 553. When the first layer of mahjong tiles 10 is pushed full, the seesaw 56 is laid flat. At this time, the seesaw 56 is flush with the upper surface of the card supporting plate 553, and the upper surface of the single-layer mahjong tiles 10 is flush with the first card pushing position 421 or slightly lower than the first card pushing position 421. The first card pushing head 73 can continue to push the tiles until the mahjong tiles 10 reach the specified number of piles, and the stacking is completed.

[0119] like Fig. 9 FIG. 5 is a schematic diagram showing the process of the card loading device 5 being pushed upward and the card supporting plate 553 being lifted upward. Fig.10 The figure shows a schematic diagram of the case where the card support plate 553 rises to the highest position during the card raising process of the horizontal push card loading device 5, that is, it is flush with or slightly higher than the mahjong machine table top 2. Fig.11 The figure shows a schematic diagram of the horizontal push card loading device 5 during the card loading process in which the card holding plate 553 rises to the highest position and the card pushing plate 544 has been pushed to the farthest position. Fig.12 FIG. 5 is a schematic diagram showing that the card supporting plate 553 rises to the highest position and the card pushing plate 544 has returned to its original position during the card lifting process of the horizontal push card loading device 5. Fig.13 It is a schematic diagram showing that after the card pushing device 5 completes the card pushing, the card supporting plate 553 descends and the rocker plate 56 is still in a flat state.

[0120] Specifically, the first way in which the horizontal push card loading device 5 first raises the cards and then pushes the cards is: the mahjong machine table top 2 is provided with four first inner card outlets 25 and a first cover plate distributed in a rectangular shape, the upper surface of the first cover plate is flush with the mahjong machine table top 2 and seals the first inner card outlet 25, and a plurality of first push rods are also distributed on the card supporting plate 553, the first cover plate is connected to the first push rod, the first card loading motor 52 drives the two lifting cranks 554 to rotate and make the card supporting plate 553 rise, thereby making the plurality of first push rods lift the first cover plate, and when the card supporting plate 553 rises to be flush with or higher than the table top, the card pushing rocker 543 pushes the card pushing plate 544 to push the mahjong tiles 10 out; further preferably, the first cover plate is fixedly connected or integrally formed with the first push rod; it is worth noting that the first cover plate can also be lifted by the mahjong tiles 10.

[0121] Specifically, the second way in which the horizontal push card loading device 5 first raises the cards and then pushes the cards is: the mahjong machine table top 2 is provided with four second inner card outlets 25 and a second cover plate in a rectangular distribution, the upper surface of the second cover plate is flush with the mahjong machine table top 2 and seals the second inner card outlet 25, and at least two second push rods are distributed on the card supporting plate 553, one side of the second cover plate is hinged to the mahjong machine table top 2 and the other side can be lifted up by at least two second push rods, the first card loading motor 52 drives the two lifting cranks 554 to rotate and make the card supporting plate 553 rise, thereby making at least two second push rods lift the second cover plate, and when the card supporting plate 553 rises to be flush with or higher than the table top, the card pushing rocker 543 pushes the card pushing plate 544 to push the mahjong tiles 10 out; it is worth noting that the second cover plate can also be lifted up by the mahjong tiles 10.

[0122] The push-on card loading device 5 in the embodiment of the application is a second implementation, which still adopts the card loading method of first raising the card and then pushing the card. The difference between this implementation and the first implementation is that there is no seesaw 56 and the structure related to the seesaw 56.

[0123] In this embodiment, 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, and the first card pushing head 73 can push the mahjong tiles onto the card supporting plate 553 through the first card pushing position 421. When the first layer of mahjong tiles 10 is full, the first card loading motor 52 drives the lifting crank 554 to rotate, so that the card supporting plate 553 descends, and the descending height is the thickness of a mahjong tile 10. Then the first card pushing head 73 can continue to push the tiles until the mahjong tiles 10 reach the specified number of piles, and the card stacking is completed.

[0124] The card raising method can adopt the card raising method of the horizontal push card loading device 5 in the first embodiment, but because the card supporting plate 553 has a descending process during the card stacking process, if the first cover plate and the first push rod are fixedly connected or integrally formed, then when the card supporting plate 553 descends, the first cover plate will also be brought down with it, which is obviously not desirable. Therefore, in order to avoid this situation, the first cover plate and the first push rod are movably connected, so that when the card supporting plate 553 is lifted or lowered within a certain height range, it will not drive the first cover plate to rise or fall, and when the card supporting plate 553 exceeds this height range, the lifting of the card supporting plate 553 can drive the first cover plate to rise or fall.

[0125] The flat-push card loading device 5 in the embodiment of this application is a third implementation mode. The difference between this implementation mode and the first implementation mode is that it adopts a card loading method of pushing the cards first and then lifting the cards, that is, the lifting mechanism is not used to control the lifting and lowering of the card supporting plate 553, but is used to control the lifting and lowering of the cover plate on the mahjong machine table top 2. The specific structure can be referred to the Chinese patent document with publication number CN104436635A.

[0126] The card stacking process is the same as that of the first embodiment.

[0127] The card raising process is as follows: after the stacking of the cards is completed, the lifting mechanism controls the cover plate to descend to a height matching the card supporting plate 553, and 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 machine tabletop 2 to complete the card raising.

[0128] The push-on license plate device 5 in this application example is a fourth implementation mode, which is different from the third implementation mode in that there is no seesaw 56 and structures related to the seesaw 56. For the specific structure, reference may be made to the Chinese patent document with publication number CN201271493Y.

[0129] The stacking method is the same as the second embodiment.

[0130] The upgrade method is the same as the third implementation method.

[0131] It is worth noting that the biggest difference between the flat push card loading device 5 in the first embodiment and the second embodiment and the flat push card loading device 5 in the third embodiment and the fourth embodiment is that:

[0132] The mahjong tiles 10 in the horizontal push card loading device 5 in the first embodiment and the second embodiment are firstly lifted onto the mahjong machine table top 2 and then the card pushing rocker 543 pushes the card pushing plate 544 to push the mahjong tiles 10 out. The mahjong tiles 10 in the horizontal push card loading device 5 in the third embodiment and the fourth embodiment are firstly pushed onto the mahjong machine table top 2 by the card pushing rocker 543 to push the card pushing plate 544 and then lifted onto the mahjong machine table top 2. That is, the space occupied by pushing the mahjong tiles 10 in the horizontal push card loading device 5 in the first and second embodiments is transferred to the mahjong machine table top 2 of the mahjong machine, thereby making the internal space of the mahjong machine more abundant and thus reducing the volume of the mahjong machine.

[0133] like Fig.19 and Fig. 22 The sloped card loading mechanism 6 shown is a first implementation mode of the embodiment of the present application. In this implementation mode, the sloped card loading mechanism 6 includes a card loading drive mechanism and a card loading bracket. The card loading bracket is provided with a first card loading guide rail 63 for storing mahjong tiles 10 and a card loading pusher 612 that moves along the first card loading guide rail 63 to implement card loading. The first card loading guide rail 63 is arranged along the width direction of the mahjong tiles 10 to store a single layer of mahjong tiles 10, and a section of the first card loading guide rail 63 close to the card outlet on the mahjong machine table top 2 is a slope section that extends obliquely upward to connect the mahjong machine table top 2. The card loading drive mechanism includes an upper card loading guide rail 63. The card chain 611, the card loading pusher 612 is installed on the card loading chain 611, the card loading chain 611 moves along the bottom groove of the first card loading guide rail 63 and matches the card loading trajectory of the mahjong tile 10; a first flap 23 is provided on the card outlet on the mahjong machine table top 2, one side of the first flap 23 is hinged to the mahjong machine table top 2 or the card loading bracket, the card loading chain 611 moves to drive the card loading pusher 612 to move, thereby pushing the mahjong tile 10 forward along the first card loading guide rail 63 and lifting the other side of the first flap 23, and then pushing the mahjong tile 10 along the slope section to the mahjong machine table top 2.

[0134] Specifically, the card loading and pushing head 612 is connected to the card loading chain 611 by sliding up and down via two lifting rods 6122. The card loading and pushing head 612 is fixed or integrally formed on the upper ends of the two lifting rods 6122. A base 6121 is fixed or integrally formed on the lower ends of the two lifting rods 6122. The two lifting rods 6122 pass through the links of the card loading chain 611 and are respectively provided with spring members 6124. The lower ends of the spring members 6124 abut against the base 6121, and the upper ends abut against the card loading chain 611. A roller 6125 is also provided on the base 6121, and a first guide rail 64 cooperating with the roller 6125 is also provided on the card loading bracket. The first guide rail 64 is located below the slope section of the first card loading guide rail 63.

[0135] 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, the first linear guide rail 6311 and the second linear guide rail 6321 are connected into one by a groove that can accommodate the card loading chain 611 and the card loading push head 612, which is convenient for installation and can improve the matching accuracy of the inner guide rail 631 and the outer guide rail 632.

[0136] Specifically, the card pushing surface on the card loading and pushing head 612 includes a vertical surface and an inclined surface 61232. It is further preferred that the vertical surface and the inclined surface 61232 have a smooth transition; when the card loading and pushing head 612 pushes cards in the first card loading guide rail 63, the card pushing surface is a vertical surface in the horizontal first linear guide rail 6311 and the second linear guide rail 6321, and the card pushing surface is an inclined surface 61232 in the first arc guide rail 6312 and the second arc guide rail 6322 that are inclined upward.

[0137] 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 needs, but also reduce the machine manufacturing cost. The first card loading guide rail 63 is preferably positioned by cooperating with the card loading bracket through a plurality of T-shaped protrusions and locked and fixed by fasteners to facilitate installation.

[0138] Specifically, one side of the first flap 23 is hinged to the mahjong tabletop 2 through a hinge, the fixed part of the hinge is fixedly connected to the bottom of the mahjong tabletop 2, the movable part of the hinge is fixedly connected to the bottom of the first flap 23, the rotating shaft of the hinge is sleeved with a torsion spring that gives the movable part a downward rotation tendency, and the fixed part of the hinge is extended to form a limiter 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 the placement of tiles and the disorder of the mahjong tiles 10. The hinge form and torsion spring reset are adopted, and the structure is simple and reliable, the volume is compact, and the cost is low.

[0139] As for the four rectangularly distributed four slope card loading mechanisms 6 in the mahjong machine:

[0140] like Fig. 20The four first card loading guide rails 63 in the four slope card loading mechanisms 6 shown are connected at the ends to form a quadrilateral, and the head and tail connections of two adjacent first card loading guide rails 63 are staggered up and down to maximize the use of space and make room for the second card pushing head 74 to facilitate the second card pushing head 74 to push cards.

[0141] like Fig.21 The four card loading chains 611 in the four slope card loading mechanisms 6 shown are connected end to end to form a closed loop and are guided by at least two diagonally arranged chain guide blocks 613, which are in smooth contact with the card loading chains 611 and are fixed on the card loading bracket or the base plate 1.

[0142] like Fig. 20 Of the two first guide rails 64 in the two adjacent ramp card loading mechanisms 6 shown, one first guide rail 64 is located below the first arc guide rail 6312 of one first card loading guide rail 63, and the other first guide rail 64 is located below the second arc guide rail 6322 of the other first card loading guide rail 63. This arrangement is because the four first card loading guide rails 63 form a rounded rectangle and are arranged in an upper and lower staggered manner, which results in the overlapping of the card pushing trajectories of the four card pushing heads during the ramp card loading process, that is, the motion trajectory of the initial segment of a card loading push head 612 and the motion trajectory of the subsequent card loading push head 612 in the final segment overlap in the horizontal direction, but a card loading push head 612 needs to be pushed horizontally in the initial segment and needs to rise in the final segment, therefore, the adjacent first guide rails 64 should be located below the first arc guide rail 6312 and the second arc guide rail 6322, respectively, to avoid overlapping of the card pushing trajectories.

[0143] Specifically, a second card loading motor 68 is also provided, and the second card loading motor 68 is located outside any slope card loading mechanism 6 and cooperates with the card loading chain 611 in transmission.

[0144] The card loading process of the slope card loading mechanism 6 is as follows: the second card loading motor 68 drives the card loading chain 611 to move in the forward direction, thereby driving the four card loading push heads 612 to move at the same time, and the card loading push heads 612 push the single-layer mahjong tiles 10 to move forward in the first card loading guide rail 63 along its width direction, and in the process of rising, the mahjong tiles 10 push up the first flap 23 until the card loading push heads 612 push all the mahjong tiles 10 onto the mahjong machine table 2, and then the second card loading motor 68 reverses to make the card loading push heads 612 return to their original position, and the first flap 23 also returns to its original position under the action of the torsion spring, thereby completing the card loading.

[0145] The sloped card loading mechanism 6 in this embodiment can make the entire card loading process smoother, so that the mahjong tiles 10 will not stagnate or get stuck due to the slope being too steep.

[0146] 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.

[0147] like Fig.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:

[0148] 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.

[0149] 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.

[0150] Specifically, a flap cam 66 and a flap push rod 67 are also provided. The flap cam 66 is transmission-connected to the first card-loading motor 52 in the horizontal push card-loading device 5. One end of the flap push rod 67 is hinged to the lattice plate 51, and the other end of the flap push 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 stop positions: flush with the mahjong machine table top 2 and docking with the second card-loading guide rail. Such an arrangement not only has a reasonable spatial layout, but also saves a card-lifting motor compared to the prior art.

[0151] The ramp card loading mechanism 6 for completing the card loading through this implementation mode can have various card loading drive mechanisms, such as using chain drive to complete the card loading, and the specific structure can refer to the Chinese patent document with publication number CN208877886U or other similar chain drive structures. The card loading can also be completed in the form of wire rope drive, and the specific structure can refer to the Chinese patent document with publication number CN105413166A or other similar chain drive structures. The card loading can also be completed in the form of synchronous belt, and the specific structure can refer to the Chinese patent document with publication number CN208694237U or other similar synchronous belt drive structures.

[0152] It is worth noting that the second embodiment of the slope card loading mechanism 6 can adopt a variety of card loading drive mechanisms because its card loading drive mechanism only acts on the horizontal section of the card loading process and the card pushing trajectories of adjacent card loading pushing heads 612 do not overlap.

[0153] The method of loading cards on the above-mentioned mahjong machine is as follows:

[0154] The mahjong tiles 10 on the shuffling tray 3 are sent to the bottom of the card inlets of the four card feeding devices 4, and are sucked up by the card suction wheels in the card feeding devices 4 to enter the card feeding channel 42 and are straightened for transportation along its length direction; the card feeding device 4 is sequentially provided with a first card pushing position 421 and a second card pushing position 422 along the direction in which the mahjong tiles 10 are sent out, and the card pushing machine head 7 pushes the single mahjong tile 10 on the first card pushing position 421 to the flat push card loading device 5, and the card pushing machine head 7 pushes the single mahjong tile 10 on the second card pushing position 422 to the slope card loading mechanism 6; when a sufficient number of mahjong tiles 10 are stored in the flat push card loading device 5 and the slope card loading mechanism 6, the arranged mahjong tiles 10 are transported to the mahjong machine tabletop 2 by the flat push card loading device 5 and the slope card loading mechanism 6.

[0155] Specifically, four inner card outlets 25 and four outer card outlets 26 are provided on the mahjong machine table top 2, the four inner card outlets 25 are rectangular in shape, and the four outer card outlets 26 are located outside the inner card outlets 25 and close to the four corners of the rectangle respectively. The flat-push card loading device 5 delivers two layers of mahjong tiles 10 to the mahjong machine table top 2 through the four inner card outlets 25, and the slope card loading mechanism 6 delivers single-layer tiles to the mahjong machine table top 2 through the four outer card outlets 26.

[0156] In the flat-push card loading device 5, a first card stacking method is: it includes a card supporting plate 553 for storing double-layer mahjong tiles 10, a seesaw 56 is provided on the card inlet side of the card supporting plate 553, the seesaw 56 is flush with the card supporting plate 553 and is staggered to avoid the arrangement, and the end of the seesaw 56 close to the first card pushing position 421 can be tilted upward; when the card 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 card pushing position 421, and the mahjong tiles 10 are pushed onto the card supporting plate 553 from the first card pushing position 421 along the seesaw 56. When the first layer of mahjong tiles 10 on the card supporting plate 553 is full, the movable end of the seesaw 56 falls down and 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 card pushing position 421, and the card pushing machine head 7 continues to push cards until the second layer of mahjong tiles 10 is full.

[0157] The second card stacking method is: it includes a card supporting plate 553 for storing double-layer mahjong tiles 10, and the card supporting plate 553 has two stop positions that match the height of the first card pushing position 421 and are at least lower than the thickness of one mahjong tile 10 at the first card pushing position 421. When the card supporting plate 553 receives the first layer of mahjong tiles 10, the card supporting plate 553 matches the height of the first card pushing position 421, and the mahjong tiles 10 are transported to the card supporting plate 553 through the first card pushing position 421. When the first layer of mahjong tiles 10 on the card supporting plate 553 is full, the card supporting plate 553 descends, and the descending height is at least the thickness of one mahjong tile 10, and the card pushing machine head 7 continues to push cards until the second layer of mahjong tiles 10 is full.

[0158] The first way of raising the cards is: when a card-raising signal is received, which is often sent by a player, the card-raising plate 553 rises to a position flush with or higher than the mahjong machine table top 2, and then the mahjong tiles 10 on the card-raising plate 553 are pushed onto the mahjong machine table top 2, and then the card-raising plate 553 descends to its original position to wait for the next round of stacking cards.

[0159] The second way of raising the cards is: when a card-up signal is received, which is often sent by a player, the cover plate on the inner card outlet 25 drops to a height matching the card-supporting plate 553, and then the mahjong tiles 10 on the card-supporting plate 553 are pushed onto the cover plate, and then the cover plate rises to be flush with the mahjong machine tabletop 2.

[0160] In the ramp loading mechanism 6, the first loading method is: when a loading signal is received, which is often sent by a player, the loading pusher 612 pushes the mahjong tiles 10 along the first loading guide rail 63 and can lift up the first flap 23 on the outgoing card opening 26 that is hinged to the mahjong machine tabletop 2 until all mahjong tiles 10 are pushed onto the tabletop, and then the loading pusher 612 returns to its original position. After the loading is completed, the mahjong tiles 10 are distributed as shown in the figure. Fig.25 shown.

[0161] The second card loading method is as follows: when a card loading signal is received, which is often sent by a player, the second flap 24 hinged to the mahjong machine table 2 on the outgoing card opening 26 falls and is connected to the second card loading guide rail, and the card loading head pushes the mahjong tiles 10 on the second card loading guide rail onto the second flap 24, and the second flap 24 is flipped up to be flush with the mahjong machine table 2. After the card loading is completed, the mahjong tiles 10 are distributed as follows Fig.26 shown.

[0162] It is worth noting that, in the description of this specification, the "flush" and "height matching" of surface A and surface B both mean that the height difference between surface A and surface B is within 5 mm.

[0163] Embodiment 2:

[0164] The similarities between the embodiment of the present application and embodiment 1 are that the structure of the card pushing machine head, the card pushing method and the lifting method of the card blocking block are different.

[0166] It is worth noting that, in this embodiment, the card pushing motor 72 is located on the side of the second card pushing head 74, and the card pushing motor 72 can also be placed on the side of the first card pushing head 73 as in Example 1, and the specific structures of the first card pushing head 73, the second card pushing head 74 and the card blocking block 75 can refer to Example 1.

[0167] like Figure 28-32 The head box 71 shown is also equipped with a card pushing head driving mechanism, which is used to control the first card pushing head 73 and the second card pushing head 74 to push cards, wherein the card pushing motor 72 drives the first card pushing head 73 to push cards in the forward direction, and the card pushing motor 72 drives the second card pushing head 74 to push cards in the forward direction, and the card pushing head driving mechanism includes a first card pushing wheel 761 and a second card pushing wheel 771 that are transmission-coordinated with the card pushing motor 72, the first card pushing wheel 761 is transmission-connected to the first card pushing head 73, the second card pushing wheel 771 is transmission-connected to the second card pushing head 74, the card pushing motor 72 drives the first card pushing wheel 761 to rotate, thereby causing the first card pushing head 73 to push cards; the card pushing motor 72 drives the second card pushing wheel 771 to rotate, thereby causing the second card pushing head 74 to push cards; and A further preferred step further includes a camshaft 792 that is in transmission cooperation with the card pushing motor 72, and a one-way bearing A791 sleeved on the camshaft 792, the first card 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 mounted on the camshaft 792, the card pushing motor 72 rotates forward to drive the first card pushing wheel 761 to rotate, thereby enabling the first card pushing head 73 to push cards, that is, the first card pushing head 73 translates and slides in and out of the first card pushing position 421 to push cards, at this time the second card pushing head 74 can push cards empty or remain stationary; the card pushing motor 72 reverses to drive the second card pushing wheel 771 to rotate, thereby enabling the second card pushing head 74 to push cards, that is, the second card pushing head 74 translates and slides in and out of the second card pushing position 422 to push cards, at this time the first card pushing head 73 remains stationary.

[0168] When the second card pushing wheel 771 is fixedly mounted on the camshaft 792, the card pushing motor 72 drives the camshaft 792 to rotate forward, the first card pushing head 73 pushes cards, the second card pushing wheel 771 rotates forward and the second card pushing head 74 pushes cards in vain; when the card pushing motor 72 drives the camshaft 792 to reverse, the first card pushing head 73 is stationary, the second card pushing wheel 771 reverses and the second card pushing head 74 pushes cards.

[0169] When the second card pushing wheel 771 is movably mounted on the camshaft 792, the camshaft 792 is also provided with a one-way bearing B793, and 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 pushes cards, 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 is reversed, and the second card pushing head 74 pushes cards.

[0170] Specifically, the head box 71 is further provided with a first swing arm 794 and a second swing arm 795, the lower end of the first swing arm 794 and the lower end of the second swing arm 795 are hinged to the 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, the upper part of the second swing arm 795 is movably matched with the second card pushing head 74, and the card pushing motor 72 drives the first card pushing wheel 761 to rotate forward, thereby driving the first The swing arm 794 swings, thereby pushing the first card pushing head 73 to push the cards. At this time, the second card pushing wheel 771 can rotate forward or stop. The card pushing motor 72 drives the second card pushing wheel 771 to rotate reversely, thereby driving the second swing arm 795 to swing, thereby pushing the second card pushing head 74 to push the cards. 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 and the first card pushing wheel 761 can refer to the specific structure of the first connecting block 70 and the first curved wheel 76 in Example 1. The specific structure of the active cooperation between the first card pushing wheel 761 and the first card pushing head 73 can refer to the specific structure of the active cooperation between the first connecting block 70 and the first card pushing head 73 in Example 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 the rolling bearing, and then the swinging of the first swing arm 794 is converted into the pushing action of the first card pushing head 73, and by arranging a tension spring or arranging a first contact surface and a second contact surface cooperating with the rolling bearing in the front and back of 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 The arm 794 returns to its original position; and the specific structure of the active cooperation between the upper part of the second swing arm 795 and the second card pushing head 74 can refer to the specific structure of the active cooperation between the first connecting block 70 and the second card pushing head 74 in Example 1, that is, the swing of the second swing arm 795 is converted into a card pushing action of the second card pushing head 74 through a rolling bearing, and by setting a tension spring or setting a first contact surface and a second contact surface that cooperate 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.

[0171] Such arrangement enables the card pushing motor 72 to rotate forward to complete the card pushing action of the first card pushing head 73, and to rotate reversely to complete the card pushing action of the second card pushing head 74. In a complete card loading process, the card pushing motor 72 has only one forward and reverse switching. Compared with Example 1, the card pushing motor 72 has one forward and reverse switching for each pushed mahjong tile 10. The card pushing head in this embodiment is more in line with the working characteristics of the card pushing motor 72, and can significantly improve the working life of the card pushing motor 72.

[0172] like Figure 28-32 The head box 71 shown is also equipped with a lifting mechanism for a card block 75, and the lifting mechanism for the card block 75 is used to control whether the card block 75 is located between the first card pushing position 421 and the second card pushing position 422. The card pushing motor rotates forward so that the card block is located between the first card pushing position (421) and the second card pushing position (422), and the card pushing motor rotates reversely so that the card block is no longer located between the first card pushing position (421) and the second card pushing position (422).

[0173] The lifting mechanism of the card blocking block 75 includes a first lifting wheel 762 and a second lifting wheel 772 that are in transmission with the card pushing motor 72. The first lifting wheel 762 and the second lifting wheel 772 are respectively connected to the card blocking block 75 in transmission. The card pushing motor 72 drives the first lifting wheel 762 to rotate so that the card blocking block 75 has a low stop position; the card pushing motor 72 drives the second lifting wheel 772 to rotate so that the card blocking block 75 has a high stop position; further preferably, it also includes a camshaft 792 that is in transmission with the card pushing motor 72, and a one-way bearing A791 and a one-way bearing A792 that are sleeved on the camshaft 792. Bearing B793, the first lifting wheel 762 is in transmission cooperation with the outer surface of the one-way bearing A791, the second lifting wheel 772 is in transmission cooperation with the outer surface of the one-way bearing B793, the card pushing motor 72 rotates forward to drive the first lifting wheel 762 to rotate so that the card blocking block 75 has a low stop position, that is, the card blocking block 75 is located between the first card pushing position 421 and the second card pushing position 422; the card pushing motor 72 rotates reversely to drive the second lifting wheel 772 to rotate so that the card blocking block 75 has a high stop position, that is, the card blocking block 75 is no longer located between the first card pushing position 421 and the second card pushing position 422.

[0174] Specifically, a rotating block 796 and a baffle spring sheet 797 are further provided in the head box 71. The baffle spring sheet 797 is installed in the head box 71. A lifting block 753 is provided on the lower surface of the baffle block 75. The baffle spring sheet 797 at one end of the rotating block 796 is movably matched, 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 connected to the rotating block 796. The moving block 796 is fixedly connected or integrally formed, the first baffle block 7961 is movably matched with the first lifting wheel 762, the second baffle block 7962 is movably matched with the second lifting wheel 772, the card pushing motor 72 drives the first lifting wheel 762 to rotate forwardly, thereby driving the rotating block 796 to rotate, and drives the lifting block 753 to descend and make the card blocking block 75 have a low stop position, that 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 reversely drive the rotating block 796 to rotate, and drives the lifting block 753 to descend and make the card blocking block 75 have a high stop position, that 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 The forward rotation of 762 can drive the rotating block 796 to rotate from the second stop surface 7964 against the baffle spring sheet 797 to the first stop surface 7963 against the baffle spring sheet 797, so that the baffle block 75 has a low stop position. 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 high stop position.

[0175] 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.

[0176] Specifically, the first lifting wheel 762 and the second lifting wheel 772 are circumferentially distributed in different areas on the camshaft 792. Such arrangement is because the first baffle plate shift block 7961 and the second baffle plate shift block 7962 are respectively located at the front and rear sides of the rotating block 796 and the two rotate together. When the first lifting wheel 762 rotates forward to drive the first block plate shift block to rotate forward to drive the lifting block 753 to descend, if the first lifting wheel 762 and the second lifting wheel 772 overlap in the circumferentially distributed area on the camshaft 792, the rotation of the second block plate shift block will be hindered; and when the second lifting wheel 772 reverses to drive the second block plate shift block to reverse to drive the lifting block 753 to ascend, if the first lifting wheel 762 and the second lifting wheel 772 overlap in the circumferentially distributed area on the camshaft 792, the rotation of the first block plate shift block will be hindered.

[0177] like Fig.33 and 34 A first camshaft sleeve 712 is also fixed in the head box 71 shown, and the camshaft 792 can rotate in the first camshaft sleeve 712. The rear end of the first camshaft sleeve 712 is sleeved with a one-way bearing C798, and the outer surface of the one-way bearing C798 is transmission-connected to the first card pushing wheel 761 and the first lifting wheel 762. The one-way bearing C798 is used to limit the reversal of the first card pushing wheel 761 and the first lifting wheel 762.

[0178] 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 one circle, and the first card-pushing head 73 completes a reciprocating linear motion of pushing a card. Then, when the next mahjong tile 10 is in place, the card-pushing motor 72 is started again to complete the next card-pushing, that is, the camshaft 792 will stop after rotating one circle to wait for the next time. Pushing cards. At this time, if 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 and fail to return to its original position completely, thereby causing a card jam and the card blocking block 75 to stay in the wrong position. After the one-way bearing C798 matched with the first camshaft sleeve 712 is set, 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.

[0179] More preferably, the first camshaft sleeve 712 and the second camshaft sleeve 713 may be integrally formed or may be two separate parts.

[0180] 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.

[0181] 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 .

[0182] 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.

[0183] 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.

[0184] 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.

[0185] In this embodiment, the card pushing process of the card pushing machine head is as follows:

[0186] like Fig.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. Fig.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.

[0187] After the push card loading device is fully loaded, Figure 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.

[0188] 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. Figure 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.

[0189] After the ramp loading mechanism is fully loaded, Fig.29 and Fig.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.

[0190] 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.
