Description

Technical Field

[0001] The invention belongs to the technical field of mahjong machines, and in particular relates to a mahjong machine. Background Art

[0002] Playing mahjong is a bridge for people to relax, communicate or enhance their feelings, and it is favored by more and more people. In response to usage needs, mahjong tables on the market are constantly being updated, with a wide variety of types and complete functions. As a popular entertainment product, automatic mahjong machines are very practical and operational. They can automatically shuffle and sort cards, which can greatly save people from the tedious steps of manual shuffling, stacking, and sorting cards during the game, saving time and providing convenience to people. For this reason, the market share of automatic mahjong machines is also increasing, and they are gradually entering entertainment venues and homes.

[0003] The structural features of the existing mahjong machine are: an opening and closing plate for inserting mahjong tiles is arranged at the center of the mahjong table. As for the card removal, one method is to arrange four slender rectangular card removal openings around the mahjong table, each of which is provided with a cover plate, and a lifting device is arranged below each card removal opening; the other method is to arrange four inclined card removal openings at a point in the middle of the mahjong table, each of which is provided with a cover plate, and the mahjong tiles are pushed onto the cover plate by a card pulling device, and the game can start after the cover plate is raised.

[0004] A turntable is provided under the opening and closing plate and the cover of the mahjong table to stir the mahjong tiles put in by opening the opening and closing plate. After stirring, the posture control mechanism configures a certain number of tiles into a two-layer structure, and the suction and delivery mechanism transports and supplies the two-layer tiles to each card distribution table, and then the transfer mechanism horizontally transfers the two-layer tiles on each card distribution table to the cover. This arrangement requires a separate motor to be designed for the head box and the card pushing mechanism, which results in at least 8 motors required for a similar structure, increasing the volume of the mahjong machine, and also increasing the weight and cost of the mahjong machine. The large number of components makes the probability of later maintenance higher, and the promotion effect is not good; moreover, the existing mahjong machines start to touch the tiles after the mahjong tiles are raised, and can only start to prepare for playing cards after touching the tiles. It also takes a certain amount of time before playing cards, which virtually prolongs the playing time of each game.

[0005] Furthermore, the operating disk lifting device of the existing mahjong machine adopts a motor-driven rocker arm to drive the lifting rod to complete the lifting of the operating disk. Since the shuffling device and the card lifting device both adopt independent driving devices, and the corresponding driving devices need to occupy a large volume in the mahjong table, the existing mahjong table needs to open a cavity under the table body specifically for accommodating the driving mechanism of the card lifting device, and due to the complex structure, high material consumption and complex installation, the production cost is high.

[0049] Example:

[0050] like Figure 1-10 As shown, this embodiment provides a mahjong machine, including a transmission mechanism for driving an operating disk and a shuffling disk, and a head box mechanism, a card pushing mechanism, a card pulling mechanism and an inclined card lifting mechanism connected in sequence, the head box mechanism includes a head box body 101 and a head box driving motor 102 installed on the head box body 101, and a driving gear 103 is arranged in the head box body 101, and the driving gear 103 is connected to the motor shaft of the head box driving motor 102, as shown in FIG. Figure 3 As shown;

[0051] like Figure 1As shown, the card pushing mechanism includes a card pushing mechanism 201, a card raising bar 202 and a sinking bar 203 which are arranged in sequence from the outside to the inside of the mahjong machine. An adjusting gear 204 is installed on the inner side of the mounting frame below the card raising bar 202 to drive the card pushing mechanism 201 to push the mahjong tiles on the card raising bar 202 onto the sinking bar 203, and drive the mahjong tiles on the sinking bar 203 to rise to the tabletop; the adjusting gear 204 is meshed with the driving gear 103 through the first gear set, so as to drive the adjusting gear 204 to rotate through the head box driving motor 102;

[0052] The card pulling mechanism includes a card pulling belt and a card pulling driving mechanism, and the card pulling driving mechanism drives the card pulling belt to pull the mahjong tiles on the card raising strip 202 that are not in contact with the card raising strip 202 to the oblique card raising mechanism, so that the oblique card raising mechanism can raise the mahjong tiles that are not in contact with the card raising strip 202 to the tabletop;

[0053] like Fig. 9 As shown, the transmission mechanism includes a transmission motor 501, a transmission gear set, a lifting member 502 and a limiting roller 503. The transmission motor 501 is connected to the lifting member 502 and the shuffling plate 504 through the transmission gear set to respectively drive the lifting member 502 and the shuffling plate 504 to rotate. The shuffling plate 504 rotates to shuffle the mahjong cards on the shuffling plate. The limiting roller 503 is fixed on the central axis 506 at the lower end of the operating plate 505, and the limiting roller 503 is arranged at the upper end of the lifting member 502 to rise and fall with the rotation of the lifting member 502. It should be noted that, as Figure 1 As stated, Figure 1 A schematic diagram of the conveying mechanism 7 is drawn in the figure, which is used for the mahjong to enter the head box mechanism through the conveying mechanism 7 after the mahjong is shuffled on the shuffling plate 504 as a large plate, and then enter the overall structure of the present invention. It should be noted that the conveying mechanism 7 is an existing structure. Since it is not described in detail, its combination relationship with the present invention is simply described here to facilitate understanding of the present technology.

[0054] The working principles of the machine head box mechanism, the card pushing and lifting mechanism, the card pulling mechanism and the oblique card lifting mechanism are as follows: the machine head box mechanism first uses the machine head box driving motor 102 to drive the upper and lower cards, and pushes all the mahjong tiles onto the card lifting bar 202 of the card pushing and lifting mechanism, and then starts the card pulling belt to pull away the multi-layer mahjong tiles on the card lifting bar 202 that are not in direct contact with it, and bring them to the oblique card lifting mechanism and then lift them to the tabletop; after the card pulling belt pulls away the multi-layer mahjong tiles on the card lifting bar 202 that are not in direct contact with it, the machine head box driving motor 102 drives the adjusting gear 204 to move through the active gear 103, and the adjusting gear 204 drives the card pushing mechanism 201 to push the remaining layer of mahjong tiles on the card lifting bar 202 onto the sinking bar 203, and then the adjusting gear 204 drives the sinking bar 203 to rise to the tabletop, and then the card game can begin.

[0055] During the use of the present invention, the head box mechanism and the card pushing mechanism can be driven by a head box driving motor 102, and the two motors that were originally needed to be used are combined into one motor to realize the head box mechanism and the card pushing mechanism, saving one motor. When applied to the whole machine, four motors can be saved. Only four motors are needed to realize the head box mechanism and the card pushing mechanism in four directions. This change only requires the addition of the driving gear 103 and the first gear set 218. The structure is simpler and more practical, saving the overall volume, weight, and number of motors of the mahjong machine, reducing the cost, and being suitable for promotion; the card pulling belt can pull the mahjong tiles on the card lifting bar 202 that are not in contact with the card lifting bar 202 to the oblique card lifting mechanism, and then use the oblique card lifting mechanism to lift them to the table top, and a layer of mahjong tiles can be left on the card lifting bar 202, such as the thirteen cards that everyone is used to. When the sinking card bar rises to the table top, the cards can be played directly, saving the time of touching the cards, that is, saving the time of playing cards, and improving the efficiency.

[0056] The present invention utilizes a driving motor to drive the gear set to rotate, which can drive the lifting member and the shuffling plate to rotate. The lifting member rotates to drive the operating plate to rise and fall. In simple terms, one motor can drive the shuffling plate and the operating plate to work at the same time, saving the number of driving devices. Combined with the head box part, five motors are saved as a whole. At the same time, the volume of the accommodating cavity below the mahjong machine can be reduced, thereby reducing the overall volume and weight, reducing material costs, and making the structure simpler than the prior art, and the installation is also simpler, which is suitable for promotion.

[0057] Further preferably, the transmission gear set includes a first transmission gear 507, a second transmission gear 508 and a third transmission gear 509. The first transmission gear 507 and the second transmission gear 508 are both connected to the motor shaft of the transmission motor 501 and used as driving wheels. The first transmission gear 507 is meshed with the tooth groove 510 at the lower end of the shuffle plate 504. The rotation of the first transmission gear 507 drives the tooth groove at the lower end of the shuffle plate to rotate, thereby controlling the rotation of the shuffle plate; the second transmission gear 508 is meshed with the third transmission gear 509, and the third transmission gear 509 is coaxially connected to the lifting member 502. The rotation of the second transmission gear 508 drives the third transmission gear 509 to rotate. The movable gear 509 rotates, and the third transmission gear 509 drives the lifting member to rotate, and the lifting member drives the operating panel to rise and fall; the diameter of the third transmission gear 509 is greater than the diameter of the second transmission gear 508, which can achieve a deceleration effect, thereby indirectly reducing the lifting speed of the operating panel; it should be noted that in this embodiment, the transmission gear set uses gears, and the gears are not easy to rot when rotating, which is in sharp contrast to the belts used in the prior art that are easy to fall off and rot, and the prior art takes a long time to maintain, and it is necessary to frequently dismantle the operating panel, the operating panel column, the barrel, the square card pulling belt, the square card walking groove and the card walking panel and other structures, which takes a lot of maintenance time and cost;

[0058] The second transmission gear 508 is connected to the motor shaft of the transmission motor 501 through a third one-way bearing. For example, when the transmission motor 501 rotates forward, the second transmission gear 508 rotates, thereby controlling the lifting and lowering of the operating disk. However, when the transmission motor 501 rotates reversely, the shuffling disk can shuffle cards, but the operating disk will not rise or fall, and will not affect playing cards. The first transmission gear 507 is connected to the motor shaft of the transmission motor 501 through a fourth one-way bearing, and the third one-way bearing and the fourth one-way bearing have opposite rotation directions. For example, when the transmission motor 501 rotates forward, the second transmission gear 508 rotates, thereby controlling the lifting and lowering of the operating disk, but the first transmission gear 507 will not rotate, thereby ensuring that the shuffling disk will not rotate. When the operating disk is lowered, the transmission motor 501 becomes reversed, the shuffling disk can shuffle cards, but the operating disk will not rise or fall, and will not affect playing cards.

[0059] It should be noted that in actual application, the above structure can use the computer motherboard to control the shuffling alarm, and control the operation panel and the shuffling panel to alarm each other:

[0060] First, if all 108 mahjong tiles are not shuffled, taking the 108 mahjong tiles played in some places as an example, the computer motherboard will alarm as soon as the plate motor rotates forward, reminding the control panel to further operate.

[0061] Second, the large disk motor rotates forward and the middle operating disk rotates upward. You can use an up light control to control the up and a down light control to control the down. If the up light control does not reach the right position, an alarm will be triggered. This can prevent the motor from being used for too long and the capacitance from being too small, which will cause forward rotation and disrupt work.

[0062] It should be further explained in this embodiment that the third transmission gear 509 and the second transmission gear 508 are meshed with each other through the fourth transmission gear 514, the diameter of the fourth transmission gear 514 is larger than the diameter of the second transmission gear 508, and the diameter of the fourth transmission gear 514 is smaller than the diameter of the third transmission gear 509, so that the effect of step-by-step deceleration can be ensured. At the same time, it should be explained that the number of the fourth transmission gear 514 can be unlimited and can be selected according to actual conditions, and the fourth transmission gear 514 is rotatably connected to the table body 6 of the mahjong machine.

[0063] It is further preferred that the lifting member 502 is a hollow sleeve structure, and a limit support shaft 511 runs through the middle through hole of the lifting member 502, and the two can rotate relative to each other, that is, the lifting member can rotate relative to the limit support shaft, and the lower end of the limit support shaft 511 is connected to the mahjong machine to ensure the stability of the limit support shaft; the third transmission gear 509 is rotatably connected to the limit support shaft 511, thereby ensuring that the third transmission gear 509 can rotate relative to the limit support shaft, that is, ensuring that the lifting member can rotate relative to the limit support shaft;

[0064] The center shaft 506 is slidably connected to the limit support shaft 511 in the vertical direction, that is to say, the limit support shaft does not hinder the cooperation between the center shaft and the lifting member, and can also ensure that the operating disk connected to the center shaft will not rotate; a limit slide groove is arranged at the upper end of the limit support shaft 511, and the limit slide groove runs through both ends of the limit support shaft 511; a limit groove 512 is arranged at the lower end of the center shaft 506, and the upper end of the limit support shaft 511 is slidably connected to the limit groove 512, and the cooperation between the limit groove 512 and the limit support shaft is used to ensure the stability of the operating disk; a limit rod is fixed in the limit groove 512, and the limit rod is matched and slidably connected to the limit slide groove, and the cooperation between the limit rod and the limit slide groove is used to ensure that the center shaft can only be lifted vertically but not rotated, thereby ensuring that the operating disk falls to the bottom trough to stabilize it;

[0065] Both ends of the limit rod penetrate the central axis 506, and both ends of the limit rod are fixed with limit rollers 503. The limit rod can be used to enhance the stability of the limit roller. It should be noted that in practice, the limit roller will also be connected to the central axis to further enhance stability.

[0066] The upper end of the lifting member 502 is a wave-shaped structure with crests and troughs, and the upper end of the lifting member 502 is symmetrically arranged with the central axis of the lifting member 502 as the center, which can ensure that during the rotation of the lifting member, the two limit rollers are located at the crests or at the troughs at the same time, thereby driving the operating panel to rise and fall;

[0067] The third transmission gear 509 is externally mounted with a sleeve cover plate 513, the lower end of the sleeve cover plate 513 is connected to the mahjong machine, and the lifting member 502 is rotationally connected to the upper portion of the sleeve cover plate 513, which plays a protective role and prevents the third transmission gear 509 from colliding with other components; a notch is provided at one end of the sleeve cover plate 513 to facilitate the meshing of the third transmission gear 509 with the second transmission gear 508, without affecting the rotation of the third transmission gear 509. It should be noted that when the fourth transmission gear 514 is installed, this is to facilitate the meshing of the third transmission gear 509 with the fourth transmission gear 514, and then the third transmission gear 509 is meshed with the second transmission gear 508 through the fourth transmission gear 514, depending on the actual situation; the upper portion of the sleeve cover plate 513 is rotationally connected to the shuffle plate 504, and a rotating groove can be actually provided between each other for limiting to ensure a stable rotation connection, or a bearing can be installed between the two to ensure a stable rotation effect between the two. The existing intermediate lifting operation plate and shuffling plate only use one bearing, which is not very stable. However, the present application provides that the operation plate and the shuffling plate each have a bearing as support, which is less laborious to rotate and has better stability. It should be noted that in practice, a cover plate will be installed inside the mahjong machine, and the fourth transmission gear 514 will be snapped into the cover plate to avoid accidental contact with the fourth transmission gear 514, which will cause its structure to be unstable and even affect its operation.

[0068] It should be further explained in this embodiment that the driving gear 103 is located between the head box driving motor 102 and the card pushing slot wheel 104 of the head box mechanism, and the card pushing slot wheel 104 is connected to the internal structure of the head box, so it is not described in detail, and the driving gear 103 is located between the head box driving motor 102 and the card pushing slot wheel 104 of the head box mechanism, which will not affect the action of the card pushing slot wheel 104, and a notch is provided on one side of the head box body 101 for the first gear set 218 to pass through the notch. The driving gear 103 is meshed with the head box driving motor 102 through a first one-way bearing, and the card pushing slot wheel 104 is connected to the head box driving motor 102 through a second one-way bearing, and the first one-way bearing and the second one-way bearing rotate in opposite directions, wherein the first one-way bearing and the second one-way bearing rotate in opposite directions, as long as the head box driving motor 102 rotates forward and reverse, different controls can be realized respectively, and there will be no mutual interference between the two; it should be noted that, if Figure 2 As shown, in practice, a mounting groove is provided on the mounting frame 211, and the first gear set 218 and the adjusting gear are installed in the mounting groove for convenience and stability.

[0069] The first gear set 218 is a reduction gear set, and the diameter of each gear in the reduction gear set is larger than the diameter of the driving gear 103 and smaller than the diameter of the adjusting gear 204, so as to reduce the speed of the driving gear 103 transmitted to the adjusting gear 204. It should be noted that in order to achieve the purpose of deceleration, in practice, the driving gear 103 will be designed to be relatively small, the speed of the head box driving motor is unchanged, and the speed of the driving gear 103 is also fixed, and then the size of the driving gear 103 and the first gear set 218 is designed according to the gap, and the gear in the first gear set 218 meshing with the driving gear 103 is designed to be larger as much as possible to achieve the deceleration effect of the speed of the head box driving motor, and directly mesh with the adjusting gear as needed, or design a larger gear, decelerate again, and then mesh with the adjusting gear, so as to achieve the deceleration effect in sequence. It should be further noted that no matter how many gears are designed in the first gear set 218, the diameters of all the gears in the first gear set 218 are larger than the diameter of the driving gear 103, but smaller than the diameter of the adjusting gear, so that stable deceleration can be ensured.

[0070] It is further preferred that a pendulum rod 105 is provided on the side of the card pushing slot wheel 104 close to the head box driving motor 102, one end of the pendulum rod 105 is rotatably connected to the inner wall of the head box body 101, and a first bearing slidably connected to the annular track groove 1041 on one side of the card pushing slot wheel 104 is installed in the middle of the pendulum rod 105, and the swing of the pendulum rod 105 can be controlled by the rotation of the card pushing slot wheel 104, which is the same as the prior art; the other end of the pendulum rod 105 is provided with a second bearing 107 connected to the card receiving seat 106 of the head box mechanism, which is used to drive the card receiving seat 106 to rise and fall, which is the same as the prior art and will not be described in detail. It should be noted that the pendulum rod 105 in this embodiment is preferably an S-shaped structure, which can appropriately increase the swing amplitude of the second bearing at the other end of the pendulum rod 105, so as to adjust the spacing of the card receiving seat 106 when it swings as needed;

[0071] The annular track groove 1041 is provided with a plurality of descending sections that cooperate with the swing rod 105 to drive the card holder 106 to descend in sequence, and an ascending section 1042 that drives the card holder 106 to ascend; the descending section includes a first descending section 1043 and a second descending section 1044. The magnetic control provided on the existing annular track groove is provided at different sections to facilitate control and change of the movement direction of the card pushing slot wheel.

[0072] What needs to be further explained in this embodiment is that a first swing 205 is installed on the adjusting gear 204, a first card support plate bracket 212 is fixed to the lower end of the sedimentation bar 203, and a first shaft rail groove 219 is arranged at the lower end of the first card support plate bracket 212. The end of the first swing 205 away from the adjusting gear 204 is arranged in the first shaft rail groove 219, and the cooperation between the swing and the shaft rail groove and the gear belongs to a mature technology, which will not be described in detail here, but simply explained that the sedimentation bar 203 uses this principle structure to achieve lifting; a first vertical limiting column 210 is arranged at the lower end of the sedimentation bar 203, and a first protrusion 217 is arranged on the inner side surface (the side facing the large plate) of the mounting frame 211 below the card lifting bar 202, and a first vertical limiting hole is arranged on the first protrusion 217, and the first vertical limiting column 210 slides correspondingly in the first vertical limiting hole to ensure the stability of the sedimentation bar 203 when it is lifted;

[0073] The upper end of the mounting frame 211 is provided with a mounting groove, in which a second protrusion 213 and a second swing 216 are provided, and a second vertical limit hole is provided on the second protrusion 213. The lower end of the card-raising strip 202 is provided with a second vertical limit column 214, and the second vertical limit column 214 is correspondingly connected to the second vertical limit hole by sliding, and the second vertical limit column 214 is a telescopic rod. The telescopic rod structure can appropriately shorten the length of the second vertical limit column 214 while achieving stable limit, so that there is no need to increase the second vertical limit column 214 where the table body 6 is located. The thickness of the device can also ensure the stability of the card-raising bar 202 when it is lifted or lowered; a second card-holding plate bracket 215 is also provided at the lower end of the card-raising bar 202, and a second shaft rail groove is provided at the lower end of the second card-holding plate bracket 215, one end of the second swing 216 is provided in the second shaft rail groove, and the other end of the second swing 216 is connected to the adjusting gear 204. This structure is similar to the lifting structure of the sedimentation bar 203, and the implementation principle is also the same, that is, the position of the shaft rail groove is controlled by the rotation of the swing, and then the sedimentation bar 203 and the card-raising bar are driven to lift or lower through the card-holding plate bracket;

[0074] A card pulling box 301 is arranged between the card raising bar 202 and the sinking bar 203, and the card pulling belt is slidably connected in the card pulling box 301. An opening is arranged on the side of the card pulling box 301 close to the mahjong tiles, and the end of the card pulling belt close to the head box body 101 extends from the opening and is connected to a card pulling block 304. The card pulling block 304 is located on the card receiving seat side of the head box mechanism before use, so that the mahjong tiles on the card raising bar 202 that are not in contact with the card raising bar 202 are pulled to the inclined card raising mechanism through the card pulling belt to drive the card pulling block 304; a card suction bar 206 is arranged on the side of the sinking bar 203 away from the card raising bar 202, which is used to magnetically suck the mahjong tiles pushed onto the sinking bar 203 to a stable state. It should be noted that the adjusting gear 204 drives the lifting of the card raising bar through the second swing, so that after the card raising bar is raised to a certain height, the card pushing mechanism 201 is used to push the mahjong tiles onto the sinking bar 203, so as to avoid conflict with the card pulling box, and the second swing and the first swing 205 are respectively located on both sides of the adjusting gear 204, and there is a certain installation angle between the two. For example, when the first swing 205 is on the top, the second swing is on the bottom, so that there is a height difference between the two, so that when the synchronous action is performed, it can be level in the middle position, and then the card pushing operation is performed. It should be further noted that the principle structure of the lifting of the card raising bar is the same as the lifting principle structure of the sinking bar 203, and the difference is only the angle difference between the first swing 205 and the second swing on the adjusting gear. It should be further noted that a certain arc chamfer can be set on the side of the card pulling box close to the sinking bar 203, so that in the process of pushing the cards, the mahjong tiles on the card raising bar are more naturally vertically set on the sinking bar 203.

[0075] It is further preferred that the lower end of the card pushing bar 207 of the card pushing mechanism 201 is connected to a U-shaped slider 208, and the U-shaped slider 208 is connected to the pushing block 209 of the card pushing mechanism 201; the U-shaped slider 208 is provided with an opening (the depth can be but is not limited to about 2 cm) on the side facing the card raising bar 202, which is used for sliding connection to the outer side of the card raising bar 202 (the side away from the operating panel) when the card pushing bar 207 pushes cards. In this way, the width of the card pushing mechanism can be appropriately shortened, and then the opening on the card raising bar can be reduced, so that the card raising bar can be lifted and lowered more firmly and the width of the entire mahjong machine can be reduced. If the size of the original mahjong machine is retained, on the basis of reducing the width of the card pushing mechanism, more space can be reserved for the shuffling plate, and then a larger mahjong can be replaced, satisfying people's satisfaction of touching big cards, thereby improving the experience.

[0076] The height of the upper end surface of the sinking bar 203 in the horizontal direction is not higher than the upper end surface of the card raising bar 202, and a card suction bar 206 is provided on the side of the sinking bar 203 away from the card raising bar 202 to improve the stability of the mahjong tiles pushed onto the sinking bar 203. When the height of the upper end surface of the sinking bar 203 in the horizontal direction is equal to or similar to the height of the upper end surface of the card raising bar 202 in the horizontal direction, the mahjong tiles on the upper end surface of the card raising bar 202 can be directly pushed horizontally to the upper end surface of the sinking bar 203, and then the sinking bar 203 rises to the tabletop, so that thirteen mahjong tiles can be placed horizontally; when the height of the upper end surface of the sinking bar 203 in the horizontal direction is lower than the height of the upper end surface of the card raising bar 202 in the horizontal direction to a distance not less than the thickness of a mahjong tile, the sinking bar 203 can be lifted to the tabletop. When the mahjong tiles on the upper end of the card bar 202 are pushed to the upper end of the sinking bar 203, the mahjong tiles will be turned upside down at an angle of 90 degrees and stand on the sinking bar, so that the mahjong tiles are set upright on the sinking bar. At this time, the card suction bar 206 is also used to maintain the stability of the mahjong tiles. In this way, when the sinking bar 203 rises to the table, thirteen mahjong tiles can be directly stood up. At this time, you can grab a card by pressing the dice and play the cards directly. Both methods change the way of playing the mahjong machine and save the time of touching the cards.

[0077] It is further preferred that the card pulling mechanism also includes a base 302, on which is provided a card transport slot 303, and the card pulling box 301 is a J-shaped structure adapted to the card pulling belt, one end of the card pulling box 301 extends from between the card lifting bar 202 and the sinking bar 203 and is arranged on the side of the card transport slot 303 facing the middle of the mahjong machine, so as to facilitate the card pulling belt inside it to drive the mahjong from the card lifting bar to the card transport slot, and finally to the oblique card lifting mechanism; a card pulling belt motor 306 and a driving gear 305 for driving the card pulling belt to slide are arranged outside the card pulling box 301, and the card pulling belt motor 306 is connected with the driving gear 305 for driving the operation of the driving gear 305. It should be noted that a notch is provided on the side of the card pulling box facing the driving gear 305, so as to facilitate the driving gear 305 to mesh with the card pulling belt through the notch, thereby driving the card pulling belt to move. It needs to be further explained that, in practice, two drive gears 305 will be set, and the two drive gears are meshed with the card pulling belt. The drive gear 305 is a double-layer structure. The upper layer is the drive gear meshed with the card pulling belt, and the lower layer is the transmission gear. The transmission gear is driven to rotate by the card pulling belt motor 306, and the transmission gear drives the driving gear to rotate. The diameter of the transmission gear is smaller than the diameter of the driving gear. In the process of the card pulling belt motor 306 meshing with the transmission gear below the driving gear, it can also rotate through multiple gears meshing in sequence. The structure is a simple transmission structure, and a reference can be given in the figure.

[0078] It is necessary to further explain in this embodiment that the oblique card-raising mechanism comprises a card track 401 and a card-raising member 402, one end of the card-raising member 402 is rotatably connected to the card track 401, and the other end of the card-raising member 402 is used to receive the mahjong tiles pulled to the oblique card-raising mechanism by the card-pulling belt. It is further preferred that a card-raising motor 403 is provided on the card track 401, the card-raising motor 403 is connected to a third swing 404 located in the card track 401, and a swing limiter 405 is provided on the inner side of the card-raising member 402, and a roller is provided at one end of the third swing 404 away from the card-raising motor 403, and a card-raising limiter chute is provided on one side of the swing limiter 405, and the roller is slidably connected to the card-raising limiter chute to realize the lifting and lowering of the card-raising plate, and its principle is the same as the lifting and lowering principle of the sinking bar. It should be noted that the above-mentioned oblique card-raising mechanism also belongs to the prior art, so only a simple structural description is made to facilitate understanding of the principle, and no specific restrictions are made.

[0079] The mahjong machine of the present invention can be referred to as a 13-card mahjong machine. When it is actually used, the large iron plate of the large plate is embedded with 6 cm, the large plate rotates counterclockwise to support the cards, and the conveying track conveys and rotates the cards on the left side of the large barrel. Taking the 108 mahjong tiles used in playing mahjong in Chengdu as an example, the machine head pushes the mahjong tiles to the right on the left side of the desktop, first one by one, and when six cards are pushed, the seventh card is three cards stacked together and pushed to the right, until all the mahjong tiles in the mahjong machine are pushed out, and then the machine head is closed.

[0080] When playing cards, when pressing the lifting switch on the operating panel, first the middle lifting operating panel and the card pulling belt are started at the same time (the light control at the head box is started. If the operating panel has finished rising, the person playing mahjong does not press the lifting switch on the operating panel again, the card pulling belt can only move to the seventh card, and the computer motherboard will naturally power off. If the lifting switch is pressed again, the middle operating panel will drop downward, and the card pulling belt will be started again to continue moving to the right). When the card pulling belt pusher carries the second layer of mahjong tiles to the seventh card (the third layer has 13 mahjong tiles), the card pulling lifting plate starts to move downward, and the inclined lifting mechanism is used to lift the mahjong tiles brought by the card pulling belt.

[0081] When the card pulling belt pusher pulls over thirteen cards, all the first swings are started to rotate downward at the same time, driving the sinking bar and all the second swings to rotate upward, driving the card raising bar to raise the cards (thirteen mahjong tiles on the card raising bar), and then using the card pushing bar of the card pushing mechanism to flip the thirteen mahjong tiles on the card raising bar at an angle of 90° to the sinking bar (the sinking bar should be lowered to a thickness lower than one mahjong tile on the card raising bar), and at the same time, the card suction bar sucks the thirteen mahjong tiles, allowing the sinking bar to rise to the table, and the inclined card raising mechanism drives the remaining mahjong tiles to rise to the table. At this time, the first swings under the four sinking bars stand upright, and the second swings under the card raising bar stand upside down. After all the card raising bars are raised and lowered, the card pulling belt pusher returns to the head box and waits for the operating panel lifting switch to send a signal again.

[0082] The large plate motor part is used to complete the rotation of the large plate and the lifting and lowering of the middle operating plate.

[0083] On the large plate motor, two layers of gears rotate. The upper layer rotates counterclockwise to drag the large plate, and the lower layer rotates clockwise to connect to the clockwise operating plate lifting gear combination, rotate the middle large plate column, and complete the lifting of the middle operating plate on the bearing that supports the middle lifting column (the large plate motor uses a one-way bearing for clockwise rotation).

[0084] The present mahjong machine reduces the middle operating panel motor, reduces the lifting motor and card pushing motor in four directions, increases the difficulty of turning over cards by 90 degrees without the need for a motor, increases the difficulty of raising and lowering cards in four directions without the need for an additional motor, increases the second vertical limit posts 214 in four directions without the need for an additional motor, increases the four-sided upright cards and stability, and is very neat when raised to the desktop.

[0085] The present mahjong machine can save people's playing time, reduce the time that people who play mahjong need to push cards on the table, and reduce the time that each person wastes on grabbing cards three to four times each time they play; the present invention reduces the need to frequently adjust the card push bar, because the present mahjong machine only needs to push 3-3.5cm, plus the width of the card pull box is about 5cm (of which 3cm is half the length of the mahjong tiles, The width of the card box is about 1.5cm, and there is an extra 0.5cm to push, in order to ensure that the mahjong is pushed onto the sinking bar). On the basis of 5cm, the opening depth of the U-shaped slider provided in the present invention is added, which is actually about 2cm. After offsetting the 5cm, only about 3cm is left, and then the chamfer on the card box is about 0.5-1cm, which offsets the remaining 3cm by about 0.5-1cm. That is, the card pushing mechanism in the mahjong machine only needs to push a distance of about 2-2.5cm compared with the prior art to push the mahjong tiles onto the sinking bar; but the original technology has 6cm of space to push (according to the 56# mahjong machine model, when pushing mahjong, at least 6cm needs to be pushed out and at least 6cm needs to be pushed to push the tiles into place. If it is less than 6cm, it will hang on the desktop panel. It can be seen that the structure of the present invention saves more space than the original technology.

[0086] This mahjong machine solves the problem that mahjong machines across the country have been trying to solve for many years. You can add multiple ways of playing mahjong without changing the machine. You can directly add mahjong tiles with multiple ways of playing across the country and continue playing (especially the large mahjong tiles used across the country have no space for adding tiles).

[0087] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
