Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, unless otherwise specified, "a plurality" means two or more unless explicitly defined otherwise.

In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

In the invention, the center of the main machine of the mahjong machine is taken as the inside, and the periphery of the main machine of the mahjong machine is taken as the outside.

An automatic mahjong machine as shown in figures 1-4 comprises a central lifting component 1, a shuffling large disk 2 and a mahjong scraping device 9 which are positioned in the center of a bottom plate 8 of a machine frame, four groups of mahjong picking and carrying systems are arranged around the periphery of the shuffling large disk 2, the mahjong picking and carrying systems comprise a mahjong conveying device 3 for picking and conveying mahjong tiles on the shuffling large disk one by one, a mahjong pushing device 4 for stacking the mahjong tiles into a pier and pushing out the pile, and a slope mahjong discharging device for conveying the arranged mahjong tiles onto a table surface of the mahjong machine along a slope, and the slope mahjong discharging device comprises a mahjong loading component 5 and a mahjong lifting component 6.

The card feeding device 3 shown in fig. 5 comprises a card feeding box 301, a card feeding channel 305 for transferring mahjong cards is arranged in the card feeding box 301, a card sucking wheel 302 is arranged at a card inlet of the card feeding channel 305, and a conveying belt 304 driven by a card feeding motor 303 is arranged in the card feeding channel 305.

In order to solve the technical problem of the prior art, namely that the arrangement of the card outlet of the card sending device and the card inlet of the card storage groove in the card loading assembly is unreasonable, so that mahjong cards pushed by the card pushing device are easy to be scattered and blocked, the inner side wall 3011 and the outer side wall 3012 of the card sending channel 305 are arc-shaped, so that the card sending channel 305 is arc-shaped and bent, an included angle is formed between the card inlet direction and the card outlet direction of the card sending channel 305, and the included angle ranges from 1 degree to 15 degrees. The mahjong tile inlet and the mahjong tile outlet of the tile feeding device shown in fig. 4 are not on the same straight line, but are staggered by a certain angle, so that the tile outlet and the tile outlet of the tile feeding device can be arranged at an included angle of 80-100 degrees with the tile pushing direction of the tile pushing device, and mahjong tiles stacked on the tile bearing block of the tile pushing device and mahjong tiles pushed by the tile pushing device are tidy and have smaller resistance. Furthermore, the card inlet of the card feeding channel 305 can be arranged at the edge of the shuffling large plate 2 which does not need to be reduced in size, thereby avoiding the reduction of the shuffling large plate 2 from influencing the shuffling-causing the limitation of the shuffling quantity and the size of the mahjong cards to be used. The included angle range of 1-15 degrees can realize the purpose, the mahjong tile conveying channel cannot influence the conveying of mahjong tiles by one conveying belt due to overlarge radian, and the included angle range can be further enlarged by arranging a plurality of conveying belts under the condition of not counting cost.

An extension part 3013 used for being connected with the other adjacent card sending device is arranged at one end of the card inlet of the card sending box 301, a card guiding block is formed at one side of the extension part 3013 close to the card inlet, so that the width of the card inlet of the card sending device is slightly larger than the width of the selected mahjong and shorter than the length of the mahjong, and the height of the card inlet is larger than the thickness of the mahjong and smaller than the width of the mahjong. The extension 3013 may be a separate component, but is preferably integrally formed with the card shoe outer sidewall. The height of the extending part 3013 is lower than that of the tile sending box, so that the tile storage groove in the tile feeding assembly can be overlapped above the tile sending box, as shown in fig. 2 and 3, the height of the main machine of the mahjong machine is reduced, the main machine of the mahjong machine is thinner, and the tile sending device of one party is arranged on the inner side of the tile storage groove in the tile feeding assembly of the same party, so that the length of the tile storage groove is prolonged, the number of the tiles is increased, and the universality of the mahjong machine for using various mahjong tiles of different sizes is improved. The invention is to superpose the card storage groove in the card feeding assembly on the extending part 3013 which can properly reduce the height, but not on the conveying part of the card feeding device (namely the conveying belt), thereby overcoming the technical problems of high host height and short card storage groove in the prior art.
