The four card outlets are arranged in a windmill shape, and each card outlet is inclined at an angle with the bottom edge of the table, namely the windmill shape is inclined, so that the table top can be made smaller, and the inclination of the card strips also accords with the habit of a player; secondly, when the card is played, the whole card pier is not built and then lifted up to the tabletop, but pushed up to the tabletop along the slope, so that the space inside the machine can be reduced, and the size of the whole machine can be reduced. However, in the card discharging device, the whole card storage groove is arranged in a slope shape, the resistance of the card feeding process is large, the load of a steel wire rope motor is large, steel wires are easy to shake and break, the card feeding process is not stable enough, the service life of the steel wire rope is low, the arrangement of the card storage groove, the stacking and pushing machine head and the conveying device (a mechanism for picking up mahjong cards from a large tray and conveying the mahjong cards to the stacking and pushing machine head) is unreasonable, the conventional square independent stacking and pushing machine head is difficult to push mahjong cards to a card inlet of a card storage groove track, and the height of a host machine is high.

The patent document with the publication number of CN102133480A discloses a full-automatic mahjong machine, which comprises a mahjong feeding system, a mahjong lifting system and a mahjong shuffling large tray, wherein the mahjong feeding system comprises four mahjong pushing devices, four mahjong feeding tracks and a chain transmission device. The height of the tile feeding system is basically level with that of the tile lifting system, so that although the height of the host is reduced, the arrangement position of the tile lifting system can cause interference to the shuffling of a large tray and the suction of the mahjong tiles by the tile feeding system, and the tile lifting system is only suitable for small mahjong tiles. In addition, the arrangement of the tile outlet of the tile feeding system and the tile inlet of the tile feeding track is unreasonable, the tile pushing device does not have the tile stacking function, and the mahjong tiles are automatically stacked on the tile bearing table board, so that the mahjong tiles are not stacked neatly and are easy to move and misplaced, and the mahjong tiles cannot enter the tile feeding track, and generate faults such as confusion in the tile feeding track. In addition, after the horizontal card feeding rail is adopted, mahjong tiles close to the card outlet of the card feeding rail are very easy to fall from the card outlet back to the shuffling large tray; the adoption of the chain and the flag wheel structure has high noise.

And, the arrangement positions of the card feeding system and the card sending system are designed in an overlapping mode, so that the height of the host is reduced. However, because the mahjong tile feeding device adopts straight lines to feed and discharge mahjong tiles, the tile outlet of the mahjong tile feeding device and the tile inlet of the tile feeding track still cannot be reasonably arranged, the tile pushing resistance of the stacking and pushing device is large and the tiles are easy to clamp, and the large arc-shaped tile feeding track causes the increase of the table surface size of the mahjong machine.

The patent documents with publication numbers of CN105381604, CN105381604 and the like disclose a mahjong machine, which comprises a central lifting component, a shuffling tray and a shuffling device, wherein the central lifting component is positioned in the center of a bottom plate of a rack, four groups of card picking and carrying systems are arranged around the shuffling tray, each card picking and carrying system comprises a card feeding device for picking up mahjong cards from the shuffling tray and feeding the mahjong cards, a card pushing device for stacking and pushing the mahjong cards into a pier, and a slope card discharging device for feeding the arrayed mahjong cards to a table top of the mahjong machine along a slope, and each slope card discharging device comprises a card feeding component and a card lifting component; the mahjong tile feeding assembly comprises a mahjong tile storage groove for storing mahjong tiles with multiple piers, the mahjong tile storage groove is provided with at least one arc-shaped bend, a mahjong tile feeding guide rail is arranged on the inner side wall of the mahjong tile storage groove, a mahjong tile feeding push head is arranged on the mahjong tile feeding guide rail in a sliding mode, and the mahjong tile feeding push head is driven by a steel wire rope mahjong tile feeding driving mechanism to slide along the mahjong tile feeding guide rail. The following disadvantages still exist in this solution, as practiced by the applicant:

1. The card feeding push head slides along the card feeding guide rail and is driven by the steel wire rope, and the problems of large friction resistance, small card feeding force, large motor load, complex structure, poor reliability, high manufacturing cost, high use and maintenance cost and the like still exist.

2. The tile feeding device and the tile lifting device are overlapped to a certain extent, so that the height of the whole mahjong machine is increased, and the mahjong machine cannot be used for a light and thin mahjong machine.

3. The setting position of the tile lifting opening of the adjacent tile picking and carrying system is greatly limited, and the use comfort of the mahjong machine is affected. Taking a mahjong machine with a square of 85cm as an example, the mahjong machine uses mahjong pieces with the size of 48mm, four rows of mahjong pieces on the table top are directly arranged into a windmill shape from the square mahjong piece lifting opening, the distance between two opposite rows of mahjong pieces is more than 35cm (the distance between two opposite mahjong piece lifting openings is 35 cm), so that the area where the mahjong pieces are placed in the habit of left hand of a player is very small (namely, the distance between the mahjong pieces and the edge of the table top frame is too small), the mahjong pieces cannot be placed, and the player is required to move the mahjong pieces to vacate the mahjong pieces area, thereby influencing the use comfort.

In this embodiment, the mahjong tile outlet direction of the tile feeding device 3 forms an included angle of 180±5° with the tile feeding direction of the tile lifting supporting plate 601 in the other group of tile picking and carrying systems which are adjacently arranged. Further preferably, the mahjong tile discharging direction of the mahjong tile feeding device 3 is parallel to the tile feeding direction of the adjacent tile lifting supporting plate 601. Therefore, the space is more compact, the length of the card storage groove is longer and more reasonable, and the card feeding device and the card lifting assembly do not overlap and deform and do not interfere with each other.

In this embodiment, the card feeding driving mechanism adopts a single push rod structure, as shown in fig. 1,2, 3 and 4, and includes a card feeding push rod 503 rotating around a fixed rotation center, a card feeding push head 505 is fixed on a rotation end of the card feeding push rod 503, and the card feeding push rod 503 is in transmission connection with a card feeding motor 5044. Specifically, the card feeding motor 5044 is fixedly installed at the lower part of the card feeding bracket 501, the output shaft of the card feeding motor 5044 extends out above the card feeding bracket 501, the output shaft of the card feeding motor 5044 is provided with a driving gear 5042, the rotating shaft of the card feeding push rod 503 is provided with a push rod gear 5043, and the driving gear 5042 is in transmission connection with the push rod gear 5043 through a transmission gear 5041. In other embodiments, the card feeding motor 5044 and the card feeding pushrod 503 may also be connected by a timing belt drive.

In the same group of card picking and carrying systems: the card feeding motor 5044 is installed between the card feeding device 3 and the card storage groove 502, and the rotation center of the card feeding pushrod 503 is located above the card feeding device 3. Therefore, the tile feeding motor and the tile feeding device are installed in a staggered mode, the structure is simple and reasonable, the space utilization rate is high, the height of a main machine of the mahjong machine is reduced, and the light and thin mahjong machine is realized.

In this embodiment, the curved angle of the card slot from the card inlet to the card outlet is 170 ° to 215 °, and the length of the card pushing rod 503 including the card pushing head 505 is 170mm to 195mm. Therefore, the moving path of the swing end of the card feeding push rod, namely the card feeding push head, is always in the card storage groove, the positions of the card feeding push head, which are close to the card inlet and the card outlet of the card storage groove, are moderate, and the large card pushing force can not cause the deflection and the large resistance of mahjong tiles. Further preferably, the arc bending angle of the card storage groove from the card inlet to the card outlet is 180+/-5 degrees. Therefore, the card feeding driving mechanism with the single push rod structure is convenient to set, the structure is simple, and the card pushing force is maximum.

The mahjong tile feeding support is provided with a sensor for detecting the position state of the mahjong tile feeding push rod or the mahjong tile feeding push head and/or the mahjong tile: for example, two sensors are respectively used for detecting and obtaining the position information when the card feeding pushing head stays outside the card inlet of the card storage groove and waits for pushing a card, and the position information when the card feeding pushing head stays outside the card outlet of the card storage groove and waits for the card lifting support plate to lift the mahjong to the tabletop. The accurate position of the card feeding push head is determined through the sensor, and the card feeding push head is fed back in time, is convenient to control, acts accurately and reduces faults. Preferably, a sensor for detecting mahjong pieces or a pushing head can be arranged at the card inlet and/or the card outlet of the card storage groove. The sensor for detecting the card pushing head can be in a direct detection mode or an indirect detection mode, for example, the driving mechanism of the card pushing head is subjected to position detection to obtain corresponding position information of the card pushing head, for example, the position information of the card pushing rod is detected to obtain the position information of the card pushing head, for example, a stepping motor or a motor with a position sensor is adopted, and the position information of the card pushing head is converted by recording the rotation travel information of the motor. The sensor may be a hall sensor, a photoelectric sensor, an ultrasonic sensor, or a contact sensor such as a limit switch.

In order to reduce the friction resistance between the mahjong pieces and the bottom of the mahjong storage groove and not to increase the cost greatly, the bottom of the mahjong storage groove is provided with a mahjong storage groove bottom patch, and the mahjong storage groove bottom patch is preferably made of a material with smooth and wear-resistant surface, such as polyoxymethylene, polytetrafluoroethylene and the like. The card storage groove bottom patch is used as an independent component to be arranged in the card storage groove of the card loading support, and the card loading support is made of materials with poor performance and low price, so that the card storage groove bottom patch can meet the use requirement, and the manufacturing cost of a machine can be reduced. The patch at the bottom of the card storage tank is preferably matched and positioned with the card feeding bracket through a plurality of buckles and locked and fixed through fasteners so as to be convenient to install. Similarly, in order to reduce frictional resistance between the mahjong pieces and the inner side wall and the outer side wall (particularly the side wall of the arc-shaped bending section) of the mahjong storage tank, and at the same time, the cost is not greatly increased, part or all of the inner side wall and/or the outer side wall of the mahjong storage tank is provided with side wall patches, and the side wall patches are preferably made of materials with smooth and wear-resistant surfaces, such as polyoxymethylene, polytetrafluoroethylene and the like. In this embodiment, the patches on the bottom, inner side wall and outer side wall of the card slot are integrally formed from a smooth wear-resistant material.

The card slot may be formed in a ramp having a gentle slope from the card entry to the card exit, but this increases the card pushing resistance of the card pusher. Therefore, preferably, most of the mahjong tiles are horizontally arranged, and the mahjong tiles in the mahjong tiles storage groove, which are close to the mahjong tiles outlet, are provided with the mahjong tiles outlet slope for lifting the mahjong tiles, so that the mahjong tiles in the mahjong tiles storage groove, which are close to the mahjong tiles outlet, are effectively prevented from falling back to the shuffling tray in the tile pushing process of the tile pushing device, and the tile feeding resistance of the tile pushing head is not excessively increased. In addition, the card storage groove is provided with a slope, so that the card lifting assembly can further prolong the length of the card lifting supporting plate in the card lifting assembly and slow down the inclined slope of the card lifting supporting plate, and the card feeding resistance is reduced. The tile discharging slope can be formed at the bottom of the tile storing tank, but is preferably arranged on a tile storing tank bottom patch, namely, most of the tile storing tank bottom patch is horizontally arranged, and the tile discharging slope capable of lifting the mahjong tiles is formed at the tile discharging opening close to the tile storing tank bottom patch. The tile feeding slope surface which is convenient for the mahjong tile to enter is formed at the tile feeding opening of the tile storage tank bottom patch. In order to avoid the occurrence of the faults of arching, jumping and the like in the mahjong tiles in the tile storage groove during the tile pushing process of the tile pushing device, a tile pressing plate for limiting the tile storage height of the tile storage groove is arranged above the tile storage groove on the tile feeding support 501, and covers part or all of the top of the tile storage groove.

In order to avoid the upward and downward displacement of the mahjong tiles on the table top of the mahjong machine, the horizontally moving tile pushing head is provided with a plurality of tile pushing parts which are respectively contacted with two mahjong tiles which are overlapped up and down in the same pier, wherein the tile pushing parts contacted with the lower layer mahjong tiles are protruded from the tile pushing parts contacted with the upper layer mahjong tiles, thus, when the upper mahjong tile pushing head pushes the multi-pier mahjong tile to move horizontally, the mahjong tile on the upper layer is behind the mahjong tile on the lower layer, and when the upper mahjong tile pushing head pushes the last pier mahjong tile to the inclined lifting support plate, the mahjong tile on the upper layer is flush with the mahjong tile on the lower layer.

In order to avoid collision of the card feeding pushing head outside the card inlet of the card storage groove and the card pushing head 401 in the card pushing device and avoid blocking mahjong tiles sent by the card sending device, the card feeding pushing head 505 and the card pushing head 401 in the card pushing device adopt a dislocation avoiding design, and are arranged on one side of the card bearing platform 402 together with the card pushing head 401 before feeding the cards.

The card blocking frame can be fixedly connected or integrally formed with the card feeding bracket, and further or integrally formed or fixedly connected with the outer side wall of the card storage groove. The card sending box, the card feeding bracket and the card lifting bracket in the square card picking and carrying system can be fixedly connected or a plurality of combined integrated forming manufacturing. In the embodiment, the card sending box and the card lifting bracket in the square card picking and carrying system are annular shells manufactured by integral forming, so that the card picking and carrying system is convenient to assemble and simple and reliable in structure.

In this embodiment, the tile pushing device with the stacking and pushing function (stacking two mahjong tiles into one pier and pushing out) is adopted, and in other embodiments, the tile stacking device for stacking two mahjong tiles into one pier and the tile pushing device for pushing the mahjong tiles stacked into one pier into the tile storage groove may also be two relatively independent devices. For example, a stacked card structure disclosed in a series of patent documents such as CN108339265A, CN106823363a is briefly described as follows:

the tile stacking device for stacking two mahjong tiles into a pier comprises a tile supporting conveyer belt arranged on a tile supporting frame, wherein the conveying direction of the tile supporting conveyer belt is basically consistent with that of a tile conveying conveyer belt, the tile supporting conveyer belt is arranged below a tile outlet of the tile conveying device, the tile supporting surface of the tile supporting conveyer belt is lower than the tile outlet of the tile conveying device by about one mahjong tile thickness, a tile blocking piece and a side blocking piece are arranged near the tile supporting conveyer belt, the tile outlet and the tile blocking piece of the tile conveying device are respectively positioned on two opposite sides of the tile supporting conveyer belt, and the tile pushing-out openings of the side blocking pieces and the tile pushing-out openings of the tile conveying device are respectively positioned on two opposite sides of the tile supporting conveyer belt. The card feed detecting device for detecting whether or not the card feed outlet of the card feed device feeds out mahjong tiles onto the card bearing conveyer belt can be arranged on the card blocking piece, but is preferably arranged on the side blocking piece so as to improve the detection precision and reliability.

The card stacking principle of the card stacking device is as follows: the first mahjong tile is sent out from the tile outlet of the tile sending channel, because the tile carrying conveying belt is lower than the tile sending conveying belt, when the first mahjong tile is sent out from the tile outlet and exceeds half of the tile sending conveying belt, the front end of the first mahjong tile falls onto the tile carrying conveying belt under the action of self gravity, the rear end of the first mahjong tile also falls onto the tile carrying conveying belt along with the conveying of the tile carrying conveying belt, and after the first mahjong tile falls onto the tile carrying conveying belt and is blocked by the blocking piece and cannot move, the second mahjong tile continues to move towards the tile carrying conveying belt, and because the height difference between the tile carrying conveying belt and the tile sending conveying belt is larger than the tile thickness, the second mahjong tile is directly stacked on the first mahjong tile, so that the stacking of one pier of mahjong tile is realized.

The tile pushing device for pushing the mahjong tiles stacked on the tile bearing conveying belt into the tile storage groove can be the movable side blocking piece, namely a relatively independent pushing head for pushing the mahjong tiles out of the tile bearing conveying belt or a tile pushing head in the tile feeding assembly, so that the tile pushing head is stopped at the opposite side of the mahjong tile pushing outlet of the tile bearing conveying belt, and the tile pushing head has two action functions: firstly, when the mahjong tiles are stored in the tile storage groove, the tile feeding pushing head pushes the mahjong tiles stacked into one pier on the tile bearing conveying belt into the tile inlet of the tile storage groove, and then returns to continue pushing the mahjong tiles of the next pier until the mahjong tiles are fully stored in the tile storage groove; secondly, after the mahjong tiles are fully stored in the tile storage groove and the tile feeding signals are received, the tile feeding pushing head sends the mahjong tiles with multiple piers in the tile storage groove to the table top of the mahjong machine along the inclined tile lifting supporting plate. Therefore, the mahjong tile rotating device is omitted, the mahjong tiles of the pier are rotationally translated and fed into the mahjong tile storage groove, the mahjong tile rotating piece and the driving motor thereof are omitted, the original stacking and pushing device and the driving motor thereof are omitted, the manufacturing cost is greatly reduced, the structure is simpler, the assembly is more convenient, the operation reliability of the mechanism is greatly improved, and the maintenance cost is greatly reduced.

More specific details of the construction of the mahjong machine using the relatively independent stacking and pushing devices and more various embodiments of the construction of the devices can be found in the series of patent documents, such as publication number CN108339265A, CN106823363 a.

In another embodiment of the tile feeding driving mechanism, as shown in fig. 7, a chain driving structure is adopted, and the tile feeding driving mechanism comprises a tile feeding chain 5046, wherein a tile feeding push head 505 is fixed on at least one chain link of the tile feeding chain 5046, the chain length of the tile feeding chain 5046 is larger than the total length of mahjong tiles stored in a tile storage groove, the running track of the tile feeding chain 5046 is matched with the running track of mahjong tiles in the tile storage groove, and the tile feeding chain 5046 is in transmission connection with a tile feeding motor 5044. The tile feeding chain 5046 runs along a fixed chain track on the tile feeding bracket 501, and the chain track can be formed by a plurality of tensioning chain wheels or transition chain wheels or can be formed by combining a plurality of transition chain wheels and a track plate, but preferably the chain track is formed by adopting a fixed chain track groove 5047, so that the running track of the tile feeding chain 5046 can be more matched with the running track of the mahjong tiles in the tile storage groove.

To reduce the running friction of the chain with the track grooves, the inner wall of the chain track groove 5047 may be made of a material with a smooth and wear-resistant surface, such as polyoxymethylene, polytetrafluoroethylene, etc., for example, in the form of a chain track seat with a smooth and wear-resistant surface, which is fixed to the upper plate support. Further preferably, the card feeding chain 5046 is in rolling contact with the chain track groove 5047 to reduce running resistance, for example, the card feeding chain is in rolling contact with the chain track groove through the rollers on the chain links, the cross section of the chain track groove is in a T shape, the two inner side walls of the chain track groove extend out to form convex strips to be in rolling contact with the rollers of the card feeding chain 5046, and in other embodiments, the rollers can also be used as the chains with the outer diameters larger than the width of the chain plates. Further preferred embodiment, the roller of the card feeding chain 5046 is of a structure with an annular groove on the circumferential surface, the annular groove is matched with the convex strips extending from the two inner side walls of the chain track groove, and the upper limit and the lower limit are realized while rolling contact, so that the moving direction and the upper position of the card feeding chain can be limited to avoid distortion blocking, and the friction contact between the bottom of the chain and the bottom of the chain track groove can be avoided to increase running resistance.

In this embodiment, the chain track groove 5047 is disposed along the inside wall of the card storage slot and the outside wall of the card lifting slot and is closed to form a loop. The chain 5046 is an open loop chain, the card feeding push head 505 is fixed at the middle section of the card feeding chain 5046, and the card feeding motor 5044 drives the card feeding chain 5046 to reciprocate through the card feeding chain wheel 5045. In other embodiments, the card feed chain 5046 may also be a closed loop chain.

For the upper card chain 5046 to be an open loop chain, the upper and lower limit structure is preferably adopted to reduce the chain movement resistance and avoid operation faults. For the chain track groove with the T-shaped cross section, the chain track seat can be manufactured and assembled into a whole by adopting the inner side wall or the outer side wall. A plurality of notches are arranged on the chain track groove for arranging the chain wheels. The chain track groove and the chain track seat are integrally annular, so that the card feeding chain can be conveniently and circularly operated.

In this embodiment, the card feeding chain 5046 is mounted above the inner side of the card storage groove 502, and the upper portion of the card feeding pusher 505 extends toward the inner side of the card storage groove 502 and is fixed to a link of the card feeding chain 5046. The structure is simple and reasonable, and the transformation is convenient relative to the existing equipment.

In this embodiment, the mounting manner of the card feeding chain may also have the following several ways:

1. The card feeding chain is a closed loop chain, is integrally connected end to end, and can be provided with a tensioning chain wheel for tensioning the card feeding chain by adopting only one actively driven card feeding chain wheel; thus, the card feeding chain can drive the card feeding push head to reciprocate along the card storage groove.

2. The card feeding chain is an open loop chain, the head and the tail are not connected, but the double card feeding chain wheels are connected with the card feeding motor in a transmission way through gears, so that the card feeding chain can drive the card feeding push head to reciprocate along the card storage groove.

3. The card feeding chain is an open loop chain, the head and the tail are not connected, only one card feeding chain wheel driven actively and the tensioning chain wheel for tensioning the card feeding chain are adopted, so that the card feeding chain can only drive the card feeding push head to reciprocate along the card storage groove.

In the open loop chain, the card pushing head is preferably arranged at the middle position of the card feeding chain, so that the front pushing and back pulling operation resistance is small.

In another embodiment, the card feeding chain can also be arranged below the card storage groove, and the lower part of the card feeding push head downwards passes through a groove at the bottom of the card storage groove and is fixed on a chain link of the card feeding chain. The mounting manner of the card feeding chain of this embodiment may be the same as that of the previous embodiment. A chain track seat with a chain track groove is arranged at the bottom of the card storage groove. Therefore, the installation of the card feeding chain is abundant, and the pushing force of the card feeding pushing head is larger and the operation is stable. However, this embodiment requires a deck or a deck conveyor belt driven by a chain, and for example, a deck pusher device of a flap structure deck disclosed in patent document CN202446788U is used. That is, the support board for receiving the mahjong pieces outside the outlet of the feeding device is in the form of a support board which can be turned over along one side, and is used as a part or an extension part of the support board or the support conveyer belt, when the feeding device feeds the mahjong pieces onto the support board or the support conveyer belt, the support board shields the chain track groove to avoid the mahjong pieces from being broken down, and when the mahjong pieces are required to be pushed by the upper push head, the support board is turned over to one side to pass by the upper push head.

In a third embodiment, the card feeding chain is mounted below or in the middle of the inner side of the card storage groove, and an opening is formed in the inner side wall of the card storage groove for extending the card feeding pushing head in the card storage groove to the inner side of the card storage groove and fixing the card feeding pushing head on the chain link of the card feeding chain. Therefore, the installation of the card feeding chain is abundant, and the pushing force of the card feeding pushing head is larger and the operation is stable. However, in this embodiment, the inner side wall of the card storage slot needs to be grooved, or all or part of the inner side wall of the card storage slot needs to be manufactured separately and then assembled on the card feeding bracket, or the inner side wall of the card storage slot may be fixed or integrally formed on the cover of the card storage slot, and then the cover is fixed on the card feeding bracket. The mounting manner of the card feeding chain of this embodiment may be the same as that of the previous embodiment. A chain track mount 5033 having a chain track slot 5047 is mounted inside the card holding slot 502 or integrally formed with the card feeding bracket.

In other embodiments, the card feeding chain and the driving mechanism thereof can be arranged outside the card storage groove. The mounting mode of the card feeding chain can be the same as the embodiment.

In the prior art, the square tile lifting assemblies are mutually independent, the tile lifting assemblies are generally fixed on the bottom plate of the rack respectively, and the tile lifting supporting plates in the tile lifting assemblies are matched with tile lifting openings on the table top of the mahjong machine, so that the square tile lifting assemblies are matched with the panel in the process of adjusting the mahjong machine, and the adjustment difficulty is high and the adjustment efficiency is low. In order to solve the problem, one embodiment of the card lifting assembly is that four card lifting brackets in four directions are integrally formed to form a card lifting integral seat, as shown in fig. 6, the card lifting assembly comprises a card lifting integral seat 602, the center of the card lifting integral seat 602 is a center hole through which a center lifting assembly can pass, four card lifting parts are arranged on the periphery of the center hole of the card lifting integral seat 602, each card lifting part comprises a first side plate and a second side plate which are arranged at intervals in parallel, a card lifting supporting plate 601 is arranged between the first side plate and the second side plate, a card lifting groove is formed between the first side plate and the second side plate, the card lifting supporting plate 601 is positioned at the upper part of the card lifting groove, one end of the card lifting supporting plate is arranged on the card lifting groove, and the other end of the card lifting supporting plate can move and is driven by a card lifting motor to lift up and down. Thus, the square rising board supporting plates are all installed on the rising board integral seat and are made into a whole, the square and the position of the square rising board supporting plates are guaranteed, and the square rising board supporting plates have the greatest advantage that the square rising board supporting plates are convenient to install and adjust the panel, and the panel can be put on. The first side plate is connected with the card lifting motor, the second side plate is positioned on the opposite side of the first side plate, and for convenient assembly and debugging, the first side plate and the second side plate are preferably manufactured by integrally forming the card lifting integral seat. However, in view of the difficulty of mold molding and the manufacturing cost, only the second side plate and the card lifting integral seat can be integrally formed, and the first side plate is a separate component and then mounted on the card lifting integral seat. In order to ensure the strength and flatness of the card lifting integral seat, a plurality of reinforcing pieces can be arranged on the card lifting integral seat, the reinforcing pieces can be a plurality of metal rods or metal pipes, and can also be integrally formed sheet metal frames or welded metal frames. The whole card lifting seat is directly fixed on the card sending boxes of the four card sending devices in the square, or the whole card lifting seat is fixed on the card sending boxes of the four card sending devices in the square through the reinforcing piece, so that the installation is convenient, the positioning and assembling precision is higher, and the integral strength, the integrity and the running stability of the main machine of the mahjong machine are also increased.

For easy assembly and debugging, the first side plate and the second side plate are preferably integrally formed with the integral bracket. However, in view of the difficulty of mold molding and the manufacturing cost, it is also possible that only the second side plate is integrally formed with the integral bracket, and the first side plate is a separate member and then mounted on the integral bracket. Other structures are the same as those of the above embodiment.

In the card picking and carrying system, the matching relationship among the card storage groove in the card loading assembly, the card bearing table in the card pushing device and the conveying channel in the card conveying device is particularly important, and the stacking and pushing process of the card pushing device is determined.

In one embodiment of the invention, the card slot has a card inlet height that is lower than the card outlet height of the card delivery device and a difference M between the two heights that is greater than the height of one mahjong tile and less than the height of two mahjong tiles, preferably 21 to 33 cm.

In another embodiment of the invention, the card slot has a card inlet height that is less than the card outlet height of the card delivery device and a height difference M between them that is less than the height of a mahjong tile, preferably 1 to 13 cm. The card pushing process is as follows: the tile-holding table 402 first holds a first mahjong tile at an initial position slightly lower than the tile outlet of the tile-delivering device; then descending one height to receive the second mahjong tile; then the card bearing table 402 is lifted to an initial position, and the height of the card bearing table is close to the height of the card inlet of the card storage groove; the piled mahjong pieces are pushed into the mahjong inlet of the mahjong storage groove 502 by the mahjong pushing head 401, and after the mahjong pushing head 401 retreats, the next mahjong piece is waited.

The two embodiments can lead the actions of the card bearing table and the card pushing head in the card pushing device to be simple and reasonable and lead the reliability to be better.

The mahjong tile arranging method of the mahjong machine comprises the following steps:

When storing mahjong pieces, the large shuffling tray rotates anticlockwise, the mahjong pieces on the large shuffling tray are picked up by the mahjong sending devices in the four groups of mahjong picking and carrying systems and are sent out to a mahjong carrying table in the mahjong pushing device after being straightened to be in the same direction, and then the mahjong pieces are pushed into a mahjong storage groove by the mahjong pushing device; waiting for a tile feeding signal when sufficient mahjong tiles are stored in a tile storage groove in the tile feeding assembly; when the mahjong pieces are loaded, the tile lifting supporting plate in the tile lifting assembly descends, the tile loading pushing head in the tile lifting assembly pushes out the mahjong pieces in the tile storage groove clockwise to the tile lifting supporting plate in the tile lifting assembly under the drive of the tile loading driving mechanism to load the tile, and after the tile loading is completed, the tile lifting supporting plate is lifted upwards to the table top of the mahjong machine.
