Description

Technical Field

[0001] The invention relates to the technical field of mahjong machine manufacturing, in particular to a four-mouth mahjong machine. Background Art

[0002] "Mahjong" is also known as mahjong (also known as "Ma Diao"), or "sparrow" for short. It is a gambling game invented by the ancient Chinese. It is a card-like entertainment tool, made of bamboo, bone or plastic, with patterns or words engraved on it. It is a game played by four people, and the rules of the game vary slightly in different regions. A deck of mahjong includes three basic suits: "Wan, Bing, and Tiao", called: Wanzi cards (Wan), Tongzi cards (Bing), and Tiaozi cards (Suo), each with 4 cards from "one" to "nine", totaling 27 kinds of 108 cards; plus 4 cards each for "East, South, West, North, Central, Fa, and White", totaling 7 kinds of 28 cards; a total of 136 cards, which is what we usually call "plain mahjong". Later, flower cards with similar functions to the "JOKER" in poker were added, usually eight cards: "Spring, Summer, Autumn, Winter, Plum, Orchid, Bamboo, Chrysanthemum", a total of 144 cards, which formed what we call "flower mahjong". There are also 8 wild cards. Therefore, a complete mahjong deck has 152 cards (74 in some regions), including character cards, flower cards, sequence cards, and wild cards. The popular version is the simplified version of mahjong, which does not include wild cards and large white cards, with a total of 144 cards. Compared with other forms of dominoes, mahjong is the most complex and interesting to play. Its basic playing method is simple and easy to get started, but there are many changes, and the combination varies from person to person. Therefore, it has become one of the most attractive gambling forms in Chinese history.

[0003] With the continuous improvement of living standards, people pay more and more attention to leisure and entertainment life, and convenient and labor-saving automatic mahjong machines are gradually becoming popular among people.

[0004] Due to the structural limitation of the push-up mechanism, the existing four-port automatic mahjong machine always pushes two cards together when pushing and playing, and there is only one row of cards in front of each person on the table. For example, the patent document with the publication number CN201164721 discloses a push-up mechanism of an automatic mahjong machine, which includes a lattice plate, a card storage plate, and a card holding device and a card pushing device respectively arranged on both sides of the card storage plate, the card holding device includes a support plate, a support plate supporting device and a card holding cam driven by a motor, a connecting rod is arranged on the card holding cam, a support plate bracket with a waist hole is arranged below the support plate, one end of the connecting rod is movably arranged in the waist hole, and a sensor is installed in the middle of the card storage plate. Since the push-up mechanism has only one fixed card storage plate, the push-up mechanism can only push out one row of cards at a time, and when starting to play cards, it is necessary to manually grab the twelve or thirteen cards for the start. In order to make up for the shortcomings of the existing four-mouth mahjong machine, the industry has developed an eight-mouth mahjong machine, which can stack and push out the twelve or thirteen cards required for the start of the game. However, the existing eight-mouth automatic mahjong machine needs to open the inner card slot and the outer card slot on the four sides of the panel, which greatly reduces the strength of the panel. The problems of warping and deformation caused by the reduced strength of the panel itself make the machine difficult to adjust or impossible to adjust. In addition, the outer card slot of the existing eight-mouth automatic mahjong machine is too far outward, overlapping with the position where the user places 13 cards, which easily causes users to feel uncomfortable when using it.

[0005] Therefore, patent documents with publication numbers CN201727950U, CN201578846U, CN101934142U, CN207913191U, CN206577363U and the like disclose a card-raising mechanism capable of enabling a four-mouth automatic mahjong machine to complete the functions of an eight-mouth automatic mahjong machine, and patent documents with publication numbers CN101983745, CN203370275U, CN203436804U, CN202446789U, CN207384806U and the like disclose a stacking device capable of stacking three mahjong tiles in one pile, and such a stacking device is suitable for a mahjong machine with a flat-push card-loading method.

[0006] In addition, the four-mouth mahjong machine has the following advantages over the eight-mouth mahjong machine:

[0007] 1) The tabletop is small, which makes it easier for players to take the cards from the other side when playing cards;

[0008] 2) The shuffling plate has a large space, which allows the mahjong tiles to be shuffled more evenly and quickly.

[0009] Unfortunately, in the existing four-mouth mahjong machines that can realize the functions of an eight-mouth mahjong machine, players are often required to manually push the two-layer mahjong tiles at the card outlet forward and / or take the single-layer mahjong tiles to the edge of the table. Compared with the full automation of the eight-mouth mahjong machine, there is still a certain gap. Summary of the invention

[0058] In the present invention, the A surface and the B surface are "flush" and "matched in height" both mean that the height difference between the A surface and the B surface is within 5 mm.

[0059] like Figure 1 , Figure 2 and Fig.17A mahjong machine shown in the figure comprises a bottom plate 1, a mahjong machine table top 2, a shuffling tray 3 located in the center and its driving mechanism, and four sets of card picking and transporting systems surrounding the shuffling tray 3. The card picking and transporting systems comprise a card feeding device 4 for picking up mahjong tiles 10 from the shuffling tray 3 one by one and delivering them, a horizontal push card loading device 5 for delivering the arranged mahjong tiles 10 onto the mahjong machine table top 2, and a card pushing machine head 6 for pushing the mahjong tiles 10 to the horizontal push card loading device 5, wherein the four horizontal push card loading devices 5 form a rectangular shape.

[0060] Specifically, the card feeding device 4 comprises a card feeding box 41, a guide plate is arranged in front of the card feeding port of the card feeding box 41, a card feeding wheel with a magnet is arranged at the card feeding port of the card feeding box 41, a tensioning wheel and a driving wheel are arranged inside the card feeding box 41, a card discharging wheel is arranged at the card discharging port of the card feeding box 41, and a conveyor belt is wrapped around the card feeding wheel, the card discharging wheel and the driving wheel and is tensioned by the tensioning wheel. The card feeding port is provided with a straight card guide groove, the width of the card feeding port is slightly larger than the width of the selected mahjong tiles 10 and shorter than the length of the mahjong tiles 10, and the height of the card feeding port is larger than the thickness of the mahjong tiles 10 and smaller than the width of the mahjong tiles 10. One, two, three or four magnets are embedded in the card feeding wheel, and the part on the outer circumference of the card feeding wheel opposite to the magnet is designed as a plane corresponding to the size of the mahjong tiles 10. After the rotation of the card feeding wheel, the mahjong tiles 10 are uniformly literal downward, and after passing through the straight card guide groove, the mahjong tiles 10 are uniformly fed in the length direction.

[0061] The running path of the mahjong tiles 10 in the card feeding device 4 is a 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 horizontal push card loading device 5. When the mahjong tiles 10 are transported to the card outlet of the card feeding channel 42, the mahjong tiles 10 are pushed into the horizontal push card loading device 5 by the card pushing machine head 6.

[0062] like Figure 1 The mahjong tabletop 2 shown in the figure is provided with four first card outlets 21, and the four first card outlets 21 are surrounded by a quadrilateral, and four horizontal push card loading devices 5 are respectively installed below the four first card outlets 21; the horizontal push card loading device 5 includes a card receiving strip 53 for arranging three layers of mahjong tiles 10 and a card pushing plate 542 for pushing the mahjong tiles 10 from the card receiving strip 53 to the mahjong tabletop 2 of the mahjong machine, the card receiving strip 53 is slidably connected with respect to the bottom plate 1 and driven to rise and fall by the card lifting driving mechanism 56, and the card pushing plate 542 is slidably connected with respect to the card receiving strip 53 and driven to push the tiles by the card pushing driving mechanism 55; when loading the tiles, the card receiving strip 53 raises the three layers of mahjong tiles 10 to the mahjong tabletop 2 via the first card outlets 21 in two times, the card pushing plate 542 pushes the two layers of mahjong tiles 10 inwardly onto the mahjong tabletop 2 of the mahjong machine, and the card pushing plate 542 pushes the single layer of mahjong tiles 10 outwardly onto the mahjong tabletop 2 of the mahjong machine.

[0063] With such arrangement, the four-mouth mahjong machine fully realizes the functions of the existing eight-mouth mahjong machine, and compared with the general eight-mouth mahjong machine, it has the advantages of a smaller mahjong tabletop 2 and a larger space for the shuffling tray 3, which makes it convenient for players to take cards during the game and makes the mahjong tiles 10 shuffled more evenly and faster; and the space occupied by the mahjong tiles 10 pushed out is transferred to the mahjong tabletop 2 of the mahjong machine, so that the internal space of the mahjong machine is more abundant, thereby reducing the size of the mahjong machine.

[0064] The pusher head 6 pushes the mahjong tiles 10 to the horizontal push loading device 5 and stacks three layers of mahjong tiles 10 on the horizontal push loading device 5 in the following manner:

[0065] One is to use a card pushing machine head 6 that can stack and push three layers of cards as disclosed in patent documents such as CN101983745, CN203370275U, CN203436804U, CN202446789U, CN207384806U or other documents. The specific structure of the card pushing machine head 6 can refer to the above patent documents. The card pushing machine head 6 generally includes a card receiving platform 61 and a card pushing head 62. When the card receiving platform 61 stacks three cards, the card pushing head 62 pushes the three overlapping mahjong tiles 10 onto the flat pushing card loading device 5; further preferably, the card receiving platform 61 has three staying positions with different heights. When the card receiving platform 61 stays at a first height, the first height is lower than the card outlet height of the card feeding device 4, and the card receiving platform 61 receives the first mahjong tile sent from the card feeding device 4. 10; then the card receiving platform 61 descends and stays at the second height, at this time, the top surface of the first mahjong tile 10 is lower than the card outlet of the card feeding device 4, and the card receiving platform 61 receives the second mahjong tile 10 sent from the card feeding channel 42, and the second mahjong tile 10 is stacked on the first mahjong tile 10; then the card receiving platform 61 descends again and stays at the third height, at this time, the top surface of the second mahjong tile 10 is lower than the card outlet of the card feeding device 4, and the card receiving platform 61 receives the third mahjong tile 10 sent from the card feeding channel 42, and the third mahjong tile 10 is stacked on the second mahjong tile 10; then the card pushing head 62 pushes the stacked three mahjong tiles 10 onto the card receiving strip 53; when there are enough three-layer mahjong tiles 10 on the card receiving strip 53, the flat-pushing card loading device 5 transports the arranged three-layer mahjong tiles 10 to the mahjong machine desktop 2.

[0066] The second is to adopt a card pushing and stacking method disclosed in a Chinese patent document with publication number CN101983745A. The specific structure of the card pushing machine head 6 can refer to the above patent document. The card pushing machine head 6 generally includes a card receiving platform 61 and a card pushing head 62. The mahjong tiles 10 are transported to the card receiving platform 61 through the card outlet of the card feeding device 4. The card pushing head 62 pushes a single mahjong tile 10 onto the card receiving bar 53. The card receiving bar 53 has three card receiving positions with different heights: a first card receiving position, a second card receiving position and a third card receiving position. When the card receiving bar 53 is at the first card receiving position, the card receiving bar 53 is not higher than the card receiving platform 61; when there are cards on the card receiving bar 53, the card receiving bar 53 is not higher than the card receiving platform 61; when there are cards on the card receiving bar 53, the card receiving bar 53 is not higher than the card receiving platform 61. After there are enough first-layer mahjong tiles 10, the card-receiving bar 53 descends to the second card-receiving position. At this time, the first-layer mahjong tiles 10 are not higher than the card-receiving platform 61, and the card-pushing head 62 pushes a single mahjong tile 10 onto the first-layer mahjong tiles 10; when there are enough second-layer mahjong tiles 10 on the first-layer mahjong tiles 10, the card-receiving bar 53 descends to the third card-receiving position again. At this time, the second-layer mahjong tiles 10 are not higher than the card-receiving platform 61, and the card-pushing head 62 pushes a single mahjong tile 10 onto the second-layer mahjong tiles 10; when there are enough third-layer mahjong tiles 10 on the second-layer mahjong tiles 10, the flat-pushing card-loading device 5 conveys the stacked three-layer mahjong tiles 10 to the mahjong machine desktop 2. Example

[0067] When the push card machine head 6 pushes the three stacked mahjong tiles 10 onto the flat push card loading device 5, as shown in FIG. Figure 3 and Figure 4 The flat push card loading device 5 shown is the first embodiment of the present application. In this embodiment, the flat push card loading device 5 includes a card receiving strip 53 for arranging three layers of mahjong tiles 10 and a card pushing plate 542 for pushing the mahjong tiles 10 from the card receiving strip 53 to the mahjong machine table top 2. The card pushing plate 542 is installed above the card receiving strip 53 through two first connecting members 543. The two first connecting members 543 are movably installed at both ends of the card receiving strip 53, and can be lifted up and down and translated inward and outward relative to the card receiving strip 53. The two first connecting members 543 are respectively movably installed at both ends of the card receiving strip 53. The first connecting members 543 are respectively fixedly connected to or integrally formed with the two ends of the card pushing plate 542; the card holding bar 53 is driven up and down by the card lifting driving mechanism 56, and the card pushing plate 542 is slidably connected inside and outside relative to the card holding bar 53 and is driven by the card pushing driving mechanism 55 to push the cards. When putting the cards on the table, the card holding bar 53 raises the three-layer mahjong tiles 10 to the mahjong machine table 2 in two times, and the card pushing plate 542 pushes the two-layer mahjong tiles 10 inward onto the mahjong machine table 2, and the card pushing plate 542 pushes the single-layer mahjong tiles 10 outward onto the mahjong machine table 2.

[0068] Specifically, the card-lifting driving mechanism 56 drives the card-holding bar 53 to rise and fall and has a first card-pushing position not higher than the mahjong machine table top 2 and a second card-pushing position not lower than the mahjong machine table top 2. When the card-holding bar 53 is located at the first card-pushing position, the card-pushing plate 542 pushes two layers of mahjong tiles 10 inward, and the distance between the bottom of the card-pushing plate 542 and the card-holding bar 53 is not less than the thickness of a mahjong tile 10. When the card-holding bar 53 is located at the second card-pushing position, the card-pushing plate 542 pushes a single layer of mahjong tiles 10 outward, and the gap between the bottom of the card-pushing plate 542 and the card-holding bar 53 is not greater than the thickness of a mahjong tile 10.

[0069] like Fig.14 and Fig.15 As shown, the card lifting drive mechanism 56 includes a first swing arm 561, a second swing arm 562 and a head box 563, and a card loading motor 52, a first card lifting cam 564 and a second card lifting cam 565 are arranged in the head box 563, the first card lifting cam 564 and the second card lifting cam 565 are drivingly connected to the card loading motor 52, the top ends of the first swing arm 561 and the second swing arm 562 are movably connected to the card bearing strip 53, and the bottom ends of the first swing arm 561 and the second swing arm 562 are respectively hinged to the head box 563. The first card-raising cam 564 is provided with a first curved groove 5641, and the second card-raising cam 565 is provided with a second curved groove 5651. The first swing arm 561 is in transmission cooperation with the first curved groove 5641, and the second swing arm 562 is in transmission cooperation with the second curved groove 5651. The card-loading motor 52 drives the first card-raising cam 564 and the second card-raising cam 565 to rotate, so that the first swing arm 561 and the second swing arm 562 swing to drive the card-receiving bar 53 to rise and fall, and has a first card-pushing position and a second card-pushing position.

[0070] It is worth noting that the first card-raising cam 564 and the second card-raising cam 565 are integrally formed or fixedly connected.

[0071] like Fig.16 and Fig.12 As shown, the card pushing drive mechanism 55 includes a card loading motor 52, two third swing arms 551 and two first sliders 545, the two first sliders 545 are respectively installed at both ends of the card receiving strip 53 and can slide inward and outward relative to the card receiving strip 53, the first connecting member 543 is installed on the first slider 545 and can slide up and down relative to the first slider 545, the lower end of the third swing arm 551 is transmission-coordinated with the card loading motor 52 and the upper end of the third swing arm 551 is movably connected with the first slider 545, the card loading motor 52 drives the third swing arm 551 to swing inward and outward, thereby driving the first slider 545 and the card pushing plate 542 to slide inward and outward on the card receiving strip 53.

[0072] Specifically, the card pushing drive mechanism 55 also includes a card pushing wheel 552, a second connecting member 553 and a transmission shaft 554. The upper end of the second connecting member 553 is transmitted and cooperated with the third curved groove 5521 through a roller. The lower end of the second connecting member 553 is fixedly sleeved on the middle section of the transmission shaft 554. The bottom ends of the two third swing arms 551 are respectively fixedly sleeved on the two ends of the transmission shaft 554. The card loading motor 52 drives the card pushing wheel 552 to rotate, which can make the second connecting member 553 swing inwards and outwards, and then make the third swing arm 551 swing inwards and outwards.

[0073] It is worth noting that the second connecting member 553 and the transmission shaft 554 can be fixedly connected or integrally formed, and the third swing arm 551 and the transmission shaft 554 can be fixedly connected or integrally formed. In the embodiment of the present application, in order to ensure a good transmission effect, the second connecting member 553, the transmission shaft 554 and the third swing arm 551 are integrally formed.

[0074] like Fig.12 As shown, the first slider 545 is provided with a first sliding groove 547 extending up and down, and the upper end of the third swing arm 551 is movably matched with the first sliding groove 547 through a roller; when the first slider 545 is lifted up and down relative to the third swing arm 551, the first slider 545 and the third swing arm 551 achieve up and down guided sliding cooperation through the first sliding groove 547; when the first slider 545 rises into place relative to the third swing arm 551, the third swing arm 551 drives the first slider 545 to slide inward and outward through the first sliding groove 547.

[0075] Specifically, at least the sixth rolling bearing, the seventh rolling bearing and the eighth rolling bearing are distributed from bottom to top on the third swing arm 551, and the first slide groove 547 is also provided on the second slider, and the sixth rolling bearing, the seventh rolling bearing and the eighth rolling bearing are in transmission cooperation with the first slide groove 547, and the second slider can slide up and down on the third swing arm 551, and during the sliding process, at least one of the sixth rolling bearing, the seventh rolling bearing and the eighth rolling bearing is in transmission cooperation with the first slide groove 547, and the third swing arm 551 swings inward and outward to drive the second slider to slide inward and outward. Further preferably, the two ends of the bottom of the card bearing bar 53 are respectively provided with support blocks 533, and the support blocks 533 are connected to the card bearing bar 53 through at least one horizontal middle guide column 534, and the second slider can translate inward and outward on the middle guide column 534.

[0076] Specifically, the third swing arm 551 includes a fourth connection part 5511 and a fifth connection part 5512 which are fixedly connected or integrally formed, the fourth connection part 5511 is connected to the transmission shaft 554, the sixth rolling bearing, the seventh rolling bearing and the eighth rolling bearing are arranged on the fifth connection part 5512, there is an angle between the fourth connection part 5511 and the fifth connection part 5512, and when the third swing arm 551 is located above the transmission shaft 554, the fourth connection part 5511 is closer to the edge of the mahjong machine relative to the fifth connection part 5512. With such arrangement, firstly, the third swing arm 551 can exert a greater force on the second slider during the rotation process to prevent the push card plate 542 component 54 from being unable to move inward and outward, and secondly, the maximum force point is transferred from the original connection between the third swing arm 551 and the transmission shaft 554 to the connection between the fourth connection part 5511 and the fifth connection part 5512, thereby improving the stability of the transmission.

[0077] like Fig.12 and Fig.13 As shown, two support blocks 533 and a first slide rail 544 are also provided. The two support blocks 533 are respectively located at both ends of the card bearing strip 53. The support blocks 533 are connected to the card bearing strip 53 through at least one middle guide column 534. The first slide rail 544 is fixedly connected to the bottom of the first connecting member 543 or is integrally formed. The second slider can translate inwards and outwards on the middle guide column 534 and slide up and down on the first slide rail 544.

[0078] It is worth noting that the first slide rail 544 can be at least one small guide post, and a blocking block 546 is fixed to the lower end of the small guide post to prevent the first slider 545 from sliding out. The upper end of the small guide post is fixedly connected to or integrally formed with the lower part of the first connecting member 543, and the first slider 545 can slide up and down on the small guide post;

[0079] The first slide rail 544 may also be a fixed block, on which a vertical slide groove is provided. The upper end of the fixed block is fixedly connected to or integrally formed with the lower portion of the first connecting member 543 , and the first sliding block 545 may slide up and down in the slide groove of the fixed block.

[0080] like Figure 3 As shown, a plurality of large guide pillars 535 are distributed between the table top 2 and the bottom plate 1 of the mahjong machine. The large guide pillars 535 pass through the support blocks 533. The support blocks 533 can slide up and down on the large guide pillars 535. Such an arrangement can ensure that the card bearing strip 53 can be lifted and lowered vertically, and during the lifting process, the second slider can be driven to slide up and down on the third swing arm 551.

[0081] like Fig.12As shown, a panel strip 541 is provided above the card pushing plate 542, and the panel strip 541 and the card pushing plate 542 are integrally formed or fixedly connected, and the panel strip 541 matches the first card outlet 21 on the mahjong machine table 2. When the mahjong tiles 10 are loaded, before the card receiving strip 53 reaches the first card pushing position, the panel strip 541 is lifted by the mahjong tiles 10 to drive the card pushing plate 542 to rise together with the card receiving strip 53. When the card receiving strip 53 is at the first card pushing position, the top of the first slider 545 is connected to the first connecting The bottom of the first connecting member 543 is not in contact. When the card-receiving bar 53 is located at the second card-pushing position, the top of the first sliding block 545 is in contact with the bottom of the first connecting member 543. Only in this way can the distance between the bottom of the card-pushing plate 542 and the card-receiving bar 53 be no less than the thickness of a mahjong tile 10 when the card-receiving bar 53 is located at the first card-pushing position, and the gap between the bottom of the card-pushing plate 542 and the card-receiving bar 53 is no greater than the thickness of a mahjong tile 10 when the card-receiving bar 53 is located at the second card-pushing position.

[0082] It is worth mentioning that when the card-holding bar 53 is located at the first card-pushing position, the top of the first sliding block 545 is not in contact with the bottom of the first connecting member 543. At this time, the panel bar 541 and the card-pushing plate 542 are supported by the mahjong tiles 10 to prevent them from falling. When the card-holding bar 53 is located at the second card-pushing position, the first sliding block 545 is against the first connecting member 543. At this time, the card-pushing plate 542 assembly 54 is supported by the first sliding block 545 to prevent it from falling.

[0083] It is worth mentioning that before the card-receiving bar 53 reaches the second card-pushing position, the first sliding block 545 contacts the first connecting member 543, and then the panel bar 541 rises together with the card-receiving bar 53. This arrangement is because if when the card-receiving bar 53 reaches the second card-pushing position, the first sliding block 545 just contacts the first connecting member 543 or the two are still not in contact, then the panel bar 541 is still supported by the mahjong tiles 10. Then, when the card-pushing plate 542 pushes the single-layer mahjong tiles 10 outward, the panel bar 541 may tip over with the two layers of mahjong tiles 10 that have been pushed inward onto the mahjong machine table 2, causing card jams.

[0084] Specifically, the first connecting member 543 includes a first connecting portion 5431, a second connecting portion 5432 and a third connecting portion 5433 that are fixedly connected or integrally formed, the first connecting portion 5431 is fixedly connected to the panel strip 541, the second connecting portion 5432 is used to connect the first connecting portion 5431 and the third connecting portion 5433, the third connecting portion 5433 can be lifted up and down relative to the first slider 545, the card pushing plate 542 is fixed on the second connecting portion 5432; the card pushing portion is provided on the inner side and the outer side of the card pushing plate 542. Further preferably, the third connecting portion 5433 is connected to a small guide column, the second connecting portion 5432 is used to connect the first connecting portion 5431 and the third connecting portion 5433, the third connecting portion 5433 is located on the outer side of the first connecting portion 5431, the card pushing portion of the card pushing plate 542 refers to the portion on the card pushing plate 542 that contacts the mahjong tile 10, and the portion protrudes relative to the second connecting portion 5432. Further preferably, the outer surface of the outer side of the pushing plate 542 includes a first vertical surface in the upper half and a first inclined surface in the lower half, the first vertical surface is located on the outer side of the outer surface of the second connecting part 5432, the bottom end of the first inclined surface is located on the inner side of the outer surface of the second connecting part 5432, and the inner surface of the pushing plate 542 at least includes a second vertical surface located in the upper half, and the second vertical surface is located on the inner side of the inner surface of the second connecting part 5432. This arrangement is because if the mahjong tile 10 is just pushed out of the first card outlet 21, then when the panel strip 541 descends, it may contact the mahjong tile 10 and bring the mahjong tile 10 into the first card outlet 21 to cause a card jam. Therefore, the mahjong tile 10 needs to be pushed to a position at a certain distance from the first card outlet 21 of the mahjong machine. Therefore, the first vertical surface is located on the outside of the outer surface of the second connecting part 5432, and the second vertical surface is located on the inside of the inner surface of the second connecting part 5432. The first inclined surface is provided so that after pushing a single card outward, the card push plate 542 and the panel strip 541 can smoothly descend into the first card outlet 21.

[0085] like Fig.13The bottom ends of the card bearing bar 53 shown are respectively provided with a first track groove 531 and a second track groove 532, the top of the first swing arm 561 is provided with a third rolling bearing, and the top of the second swing arm 562 is provided with a fourth rolling bearing, the third rolling bearing is in transmission cooperation with the first track groove 531, and the fourth rolling bearing is in transmission cooperation with the second track, during the swinging process of the first swing arm 561 and the second swing arm 562, the third rolling bearing reciprocates in the first track groove 531, and the fourth rolling bearing reciprocates in the second track groove 532, so that when the top of the first swing arm 561 and the top of the second swing arm 562 swing toward each other, the card bearing bar 53 rises, and when the top of the first swing arm 561 and the top of the second swing arm 562 swing away from each other, the card bearing bar 53 falls. With such arrangement, when the first swing arm 561 and the second swing arm 562 are swinging toward each other, the card receiving bar 53 is always in an ascending state or has an ascending trend, and the ascending distance and ascending rate of the card receiving bar 53 are increased; and when the first swing arm 561 and the second swing arm 562 are swinging away from each other, the card receiving bar 53 descends.

[0086] Specifically, the height of the pusher plate 542 is less than the thickness of two mahjong tiles 10. This is because in the embodiment of the present application, the panel strip 541 is lifted by the mahjong tiles 10 and needs to push two layers of mahjong tiles 10 inward, so the height of the pusher plate 542 needs to be less than the thickness of two mahjong tiles 10.

[0087] Specifically, the card-loading motor 52 for raising the card and the card-loading motor 52 for pushing the card can be two motors or the same motor. In the embodiment of the present application, the card-loading motor 52 for raising the card and the card-loading motor 52 for pushing the card are the same motor, and the card-loading motor 52 is directly connected to a transmission main shaft or connected through a gear transmission, and the first card-raising cam 564, the second card-raising cam 565 and the card-pushing wheel 552 are fixedly mounted on the transmission main shaft.

[0088] Specifically, a large baffle 57 is provided, and the large baffle 57 is installed on the bottom plate. When the push plate 542 pushes the two-layer mahjong tiles 10 inward, the inner side of the single-layer mahjong tiles 10 abuts against the large baffle 57. This is arranged because when the push plate 542 pushes the two-layer mahjong tiles 10 inward, the bottom layer mahjong tiles 10 will be driven to move inward together, so the large baffle 57 is needed to prevent the bottom layer mahjong tiles 10 from moving inward.

[0089] The card loading process of the flat push card loading device 5 in the embodiment of the present application is as follows:

[0090] like Figure 5As shown, when there are enough three-layer mahjong tiles 10 on the card receiving strip 53, the card receiving signal is waited, and the card receiving signal is generally sent by the player through a button. When the mahjong machine receives the card receiving signal sent by the player, the card receiving motor 52 drives the first card raising cam 564, the second card raising cam 565 and the card pushing wheel 552 to rotate, so that the first swing arm 561 and the second swing arm 562 swing towards each other, and then the card receiving strip 53 rises. In the process of rising, the panel strip 541 is lifted by the mahjong tiles 10 and the card pushing plate 542 is driven to rise. In this process, the third swing arms 551 at the left and right ends of the transmission shaft 554 are stationary, and the card receiving strip 53 drives the second slider and the first slider 545 to rise vertically until the card receiving strip 53 reaches the first card pushing position. At this time, the top of the first slider 545 is still a certain distance from the first connecting member 543.

[0091] like Figure 6 As shown, when the card bearing bar 53 reaches the first card pushing position, the card loading motor 52 continues to drive the first card raising cam 564, the second card raising cam 565 and the card pushing wheel 552 to rotate. At this time, the first swing arm 561 and the second swing arm 562 are stationary, and the third swing arms 551 at the left and right ends of the transmission shaft 554 swing inward to drive the second slider and the card pushing plate 542 assembly 54 to slide inward, thereby causing the card pushing plate 542 to push two layers of cards inward. In this process, the card pushing plate 542 assembly 54 is supported by the mahjong tiles 10 to prevent the card pushing plate 542 assembly 54 from falling.

[0092] like Figure 7 As shown, when the card pushing plate 542 has completed pushing two layers of cards inward, the card loading motor 52 continues to drive the first card raising cam 564, the second card raising cam 565 and the card pushing wheel 552 to rotate, so that the first swing arm 561 and the second swing arm 562 swing toward each other and then the card receiving bar 53 rises, and in the rising process, the third swing arms 551 at the left and right ends of the transmission shaft 554 are stationary, the panel bar 541 and the card pushing plate 542 are stationary, and the card receiving bar 53 drives the second slider and the first slider 545 to rise vertically until the first slider 545 rises to contact with the first connecting member 543, and then the rising of the card receiving bar 53 can drive the panel bar 541 and the card pushing plate 542 to rise until the card receiving bar 53 reaches the second card pushing position;

[0093] like Figure 8 and Fig. 9As shown, when the card bearing bar 53 reaches the second card pushing position, the card loading motor 52 continues to drive the first card raising cam 564, the second card raising cam 565 and the card pushing wheel 552 to rotate. At this time, the first swing arm 561 and the second swing arm 562 are stationary, and the third swing arms 551 at the left and right ends of the transmission shaft 554 swing outward to drive the second slider and the card pushing plate 542 assembly 54 to slide outward, thereby causing the card pushing plate 542 to push the single layer of cards outward. In this process, the card pushing plate 542 assembly 54 is supported by the first slider 545 to prevent the card pushing plate 542 assembly 54 from falling.

[0094] like Fig.10 and Fig.11 As shown, after the card pushing plate 542 completes pushing a single layer of cards outward, the card loading motor 52 continues to drive the first card lifting cam 564, the second card lifting cam 565 and the card pushing wheel 552 to rotate. At this time, the first swing arm 561 and the second swing arm 562 swing away from each other and then the card receiving bar 53 descends. During this process, the third swing arms 551 at the left and right ends of the transmission shaft 554 remain stationary until the card receiving bar 53 descends to the initial position and the card loading is completed. Example

[0095] This implementation manner is different from the embodiment in that the transmission structures of the card loading motor driving the card pushing drive mechanism and the card lifting drive mechanism are different.

[0096] Specifically, the card loading motor is connected to the card pushing drive mechanism and the card lifting drive mechanism through a gear transmission device; the gear transmission device includes a left lifting gear, a driving gear, a push-pull gear and a right lifting gear installed on the lattice plate and meshing with each other in sequence, and the driving gear is connected to the output shaft of the card loading motor; the first swing arm and the second swing arm are respectively installed on the left lifting gear and the right lifting gear, and the card pushing wheel is fixedly connected to the push-pull gear, so that when the card loading motor drives the driving gear to rotate to drive the left lifting gear, the push-pull gear and the right lifting gear to rotate, the card bearing bar is lifted and lowered and has a first card pushing position below the mahjong machine table top and a second card pushing position above the mahjong machine table top during the rising process, and the card pushing plate pushes two layers of cards inward and then pushes a single layer of mahjong cards outward.

[0097] Specifically, a lifting curve portion movably cooperates with the top end of the first swing arm and the top end of the second swing arm, and a spring portion for preventing the card holding bar from falling rapidly are provided below the card holding bar. The card loading motor drives the driving gear to make the first swing arm and the second swing arm rotate towards each other, and then through the cooperation between the top end of the first swing arm and the second swing arm and the lifting curve portion, the card holding bar has a first card pushing position lower than the mahjong machine table top and a second card pushing position higher than the mahjong machine table top during the rising process. When the card holding bar descends from the second card pushing position, the spring portion can make the card holding bar slowly descend.

[0098] The licensing process of the embodiment of the present application is consistent with the licensing process described in Example 1.

[0099] The method of loading cards on the above-mentioned mahjong machine is as follows:

[0100] 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 along their length direction to be transported to the card receiving platform 61 of the card pushing machine head 6, and the card pushing head 62 of the card pushing machine head 6 pushes the mahjong tiles 10 on the card receiving platform 61 to the card receiving strip 53 of the horizontal pushing card loading device 5, until there are enough three-layer mahjong tiles 10 on the card receiving strip 53, the card receiving strip 53 rises, and then the card pushing plate 542 pushes the two-layer mahjong tiles 10 inward onto the mahjong machine table top 2, and pushes the single-layer mahjong tiles 10 outward onto the mahjong machine table top 2.

[0101] Specifically, four rectangular first card outlets 21 are provided on the mahjong machine table 2, and the card receiving bar 53 carries three layers of mahjong tiles 10 to the mahjong machine table 2 via the first card outlets 21. When the card receiving bar 53 rises to the first card pushing position, at this time, the bottom surface of the second layer of mahjong tiles 10 is higher than the mahjong machine table 2, and the mahjong tiles 10 of the upper two layers are pushed inward onto the mahjong machine table 2, and then the card receiving bar 53 continues to rise to the second card pushing position. At this time, the bottom surface of the bottom layer of mahjong tiles 10 is lower than the mahjong machine table 2, and the bottom layer of mahjong tiles 10 is pushed outward onto the mahjong machine table 2.

[0102] Specifically, a card loading motor 52, a panel strip 541 fixedly connected to or integrally formed with the card pushing plate 542, and two first connecting members 543 are also provided. The card loading motor 52 is respectively matched with the card receiving strip 53 and the card pushing plate 542 in transmission. The panel strip 541 is located at the first card outlet 21 and is flush with the mahjong machine tabletop 2. The two first connecting members 543 are respectively movably mounted at both ends of the card receiving strip 53 through first sliders 545. The first slider 545 is movably mounted on the card receiving strip 53 and can be translated inward and outward relative to the card receiving strip 53. A connecting member 543 can be raised and lowered relative to the first slider 545, and the card loading motor 52 drives the card receiving bar 53 with enough rows of three layers of mahjong tiles 10 to rise, and the panel bar 541 is lifted by the mahjong tiles 10 before reaching the first card pushing position. When the card receiving bar 53 reaches the first card pushing position, the card loading motor 52 drives the card pushing plate 542 to push the upper two layers of mahjong tiles 10 onto the mahjong machine table top 2, and then drives the card receiving bar 53 to continue to rise to the second card pushing position, and then drives the card pushing plate 542 to push the bottom layer of mahjong tiles 10 outward onto the mahjong machine table top 2.

[0103] Specifically, a first swing arm 561 and a second swing arm 562 are provided for transmission cooperation with the card loading motor 52. The top ends of the first swing arm 561 and the second swing arm 562 are movably cooperated with the card receiving bar 53. The card loading motor 52 can drive the first swing arm 561 and the second swing arm 562 to rotate to realize the up and down movement of the card receiving bar 53, and make the card receiving bar 53 have a first card pushing position lower than the mahjong machine table top 2 and a second card pushing position higher than the mahjong machine table top 2.

[0104] Specifically, two third swing arms 551 are provided for transmission cooperation with the card-loading motor 52, and a first slide groove 547 extending up and down is provided on the first sliding block 545. The two third swing arms 551 are distributed at both ends of the card-loading motor 52 and movably cooperate with the first slide groove 547 through rollers. The card-loading motor 52 can drive the two third swing arms 551 to swing inwards and outwards to realize the inward and outward pushing of the card pushing plate 542.

[0105] Specifically, the mahjong tile 10 is transported to the card receiving platform 61 through the card outlet of the card feeding device 4. The card receiving platform 61 has three stopping positions with different heights. When the card receiving platform 61 stops at a first height, the first height is lower than the card outlet height of the card feeding device 4, and the card receiving platform 61 receives the first mahjong tile 10 sent from the card feeding device 4; then the card receiving platform 61 descends and stops at a second height. At this time, the top surface of the first mahjong tile 10 is lower than the card outlet of the card feeding device 4, and the card receiving platform 61 receives the second mahjong tile 10 sent from the card feeding channel 42. The second mahjong tile 10 is stacked on the first mahjong tile 10; then the card receiving platform 61 descends again and stays at the third height.
