Description

TECHNICAL FIELD

[0001] The utility model relates to mahjong machine technical field, concretely relates to automatic mahjong machine. BACKGROUND

[0002] Mahjong is a popular intellectual game, after finishing a round of combat, needs to carry out the shuffling, this step is more complicated time -consuming, for this utility model can automatic mahjong machine. The existing automatic mahjong machine includes host computer, is equipped with the shuffling chamber in the host computer, is equipped with a shuffling disc in the center of shuffling chamber, the mahjong that pushes into the card mouth on the tabletop falls into the shuffling chamber, through the rotation of shuffling disc, not only will mahjong be in disorder, but also can make mahjong turn to the same face up, thereby facilitating the capture of the card feeding assembly and then carding.

[0003] The existing shuffling chamber has only one shuffling disc, all mahjong is stacked on the shuffling disc, and the shuffling efficiency is low, and the noise is also relatively large. Influenced by motor power and other factors, the diameter of a single shuffling disc cannot be too large, and the size of the shuffling chamber is determined according to the size of the shuffling disc, so that the space utilization rate is reduced.

[0004] Therefore, at least two shuffling discs are arranged in the shuffling chamber to solve the above technical problems, but the structure of the card inlet is basically unchanged, and the original shuffling disc is located directly below the card inlet. The mahjong can be directly dropped on the shuffling disc after being pushed into the card inlet. However, there are at least two shuffling discs in the shuffling chamber. If one shuffling disc is directly below the card inlet, the distribution of mahjong on the shuffling disc will be uneven. Therefore, no shuffling disc is located directly below the card inlet, which raises the problem of how to guide the mahjong pushed into the card inlet to the shuffling disc. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing an automatic mahjong machine, which can effectively solve the problem of how to guide the mahjong pushed into the card inlet to the shuffling disc.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical scheme:

[0007] The automatic mahjong machine comprises a host computer, the host computer comprises a shuffling chamber and a tabletop located above the shuffling chamber, the tabletop is provided with a card inlet for pushing mahjong into the shuffling chamber, the shuffling chamber is provided with a card guide and at least two adjacent shuffling discs, the card guide is provided with a card guide surface for guiding the mahjong dropped from the card inlet to the shuffling disc, the card guide surface is located between the card inlet and the shuffling disc, and the horizontal height of the side of the card guide surface close to the card inlet is greater than that of the side of the card guide surface close to the shuffling disc.

[0008] In the automatic mahjong machine, the guide plate surface is located on the outer periphery of the shuffling disc close to the tile inlet, and the blocking surface is located on the outer periphery of the shuffling disc away from the tile inlet. The blocking surface and the guide plate surface form a closed ring to enclose the shuffling disc. During the shuffling process, the mahjong tiles are subjected to centrifugal force generated by the rotation of the shuffling disc and gravity, etc. This structure can prevent the mahjong tiles from sliding off the shuffling disc or moving to other areas due to the force, ensuring that the mahjong tiles always perform shuffling actions within the specified shuffling disc range, improving the stability and accuracy of shuffling.

[0009] In the automatic mahjong machine, the blocking surface and the guide plate form a closed ring to enclose the shuffling disc. The blocking surface and the guide plate form a closed ring to enclose the shuffling disc, allowing each shuffling disc to work in a relatively independent and stable space environment. During the shuffling process, the rotation of each shuffling disc and the movement of the mahjong tiles do not interfere with each other, avoiding problems such as mahjong tile chaos and increased collisions caused by the mutual influence between adjacent shuffling discs, ensuring that each shuffling disc can efficiently shuffle the mahjong tiles in the expected manner, thereby improving the shuffling stability and reliability of the entire automatic mahjong machine. Since it is a closed ring, the mahjong tiles entering the shuffling disc will have more opportunities to be scattered and turned over.

[0010] In the automatic mahjong machine, the guide plate is provided with a connecting member connecting the corresponding blocking surface and guide plate surface. The guide plate, blocking surface and guide plate surface form an organic whole structure, better separating the shuffling discs. During frequent shuffling operations of the automatic mahjong machine, this connection structure can better withstand the impact of mahjong tiles, vibrations and various stresses generated by machine operation, reducing the risk of relative displacement and loosening between components, thereby improving the stability and reliability of the entire structure and ensuring the continuous and effective function of the guide plate and blocking function during long-term use.

[0011] In the automatic mahjong machine, the bottom edge of the guide plate surface and the bottom surface of the separator are lower than the contact surface of the shuffling disc and the mahjong tiles. The mahjong tiles are more likely to smoothly slide along the guide plate surface under the action of gravity, reducing the possibility of mahjong tile jamming and accumulation due to a high bottom surface, making the mahjong tile guiding process more smooth and helping to improve the shuffling efficiency of the entire automatic mahjong machine.

[0012] In the automatic mahjong machine, the blocking surface and the guide surface enclose a ring with a gap, and the gap communicates adjacent shuffle discs. This communication structure can make the mahjong tiles adjust and redistribute between different shuffle discs according to the actual situation. If there are too many mahjong tiles in a shuffle disc, the mahjong tiles can overflow from the gap to the adjacent shuffle disc, which can speed up the shuffling speed and avoid the situation that there are too many or too few mahjong tiles in some shuffle discs, further optimize the distribution balance of mahjong tiles on multiple shuffle discs, and improve the shuffling efficiency.

[0013] In the automatic mahjong machine, the second separation ridge is formed between adjacent blocking surfaces. By setting the second separation ridge, the mahjong tiles are prevented from being stuck between adjacent blocking surfaces, and the mahjong tiles cannot stay after encountering the second separation ridge and directly fall into the shuffle disc.

[0014] In the automatic mahjong machine, the bottom end of the second separation ridge is lower than the horizontal height of the shuffle disc. The mahjong tiles are prevented from being stuck between the second separation ridge and the shuffle disc, and the mahjong tiles can be guided into the shuffle disc.

[0015] In the automatic mahjong machine, the guide member further includes a first separation ridge between adjacent guide surfaces. By setting the first separation ridge, the mahjong tiles are prevented from being stuck between adjacent guide surfaces, and the mahjong tiles cannot stay after encountering the first separation ridge and will be guided to the adjacent guide surface and fall into the shuffle disc.

[0016] In the automatic mahjong machine, the bottom end of the first separation ridge is lower than the horizontal height of the shuffle disc. The mahjong tiles are prevented from being stuck between the first separation ridge and the shuffle disc, and the mahjong tiles can be guided into the shuffle disc.

[0017] In the automatic mahjong machine, the height of the guide plate surface gradually decreases and the width gradually increases from the center of the shuffling bin to the edge of the corresponding shuffling disc. The height of the guide plate surface gradually decreases and the width gradually increases from the center of the shuffling bin to the edge of the corresponding shuffling disc, which conforms to the movement law of mahjong tiles under the action of gravity. The gradual decrease in height provides a natural sliding slope for the mahjong tiles, enabling them to move more smoothly from the tile inlet to the shuffling disc; the gradual increase in width provides a wider space for the mahjong tiles, avoiding congestion or poor sliding of the mahjong tiles due to narrow space during the guiding process. Thus, the guiding efficiency of the mahjong tiles from the tile inlet to the shuffling disc is effectively improved, the residence time of the mahjong tiles on the guide plate surface is reduced, and the shuffling process is accelerated. The design enables the mahjong tiles to be more evenly distributed to each shuffling disc. Due to the special shape of the guide plate surface, the mahjong tiles can be guided to slide in an orderly manner, avoiding the accumulation or uneven distribution of the mahjong tiles in a certain area, so that each shuffling disc is in a relatively balanced state when initially receiving the mahjong tiles. This is conducive to the subsequent shuffling process of each shuffling disc operating on approximately the same number and distribution state of mahjong tiles, thereby improving the shuffling uniformity of the entire automatic mahjong machine and enhancing the shuffling effect and quality, providing a more fair game environment for players.

[0018] In the automatic mahjong machine, the bottom edge of the guide plate surface is arc-shaped and matches the curvature of the outer circle of the shuffling disc, and the two are gap-fitted. The arc-shaped design of the bottom edge of the guide plate surface matches the curvature of the outer circle of the shuffling disc and is gap-fitted, which ensures that the guide plate surface does not affect the normal operation of the shuffling disc during the guiding of the mahjong tiles, avoids the mahjong tiles being stuck in the gap between the guide plate surface and the shuffling disc, ensures that the mahjong tiles can smoothly slide from the guide plate surface to the shuffling disc, maintains the smoothness of the shuffling process, avoids equipment failure and shuffling interruption caused by card jamming, and improves the operation stability and reliability of the automatic mahjong machine.

[0019] In the automatic mahjong machine, all the shuffling discs are arranged on a circular track with the center of the shuffling bin as the center, the guide plate piece is located at the center of the shuffling bin, and the tile inlet is located directly above the guide plate piece. This layout enables the mahjong tiles to be guided in a more balanced manner to the surrounding shuffling discs after falling from the tile inlet. Compared with a chaotic layout, this design makes full use of the space of the shuffling bin, reduces the mutual interference and collision of the mahjong tiles during the guiding process, improves the efficiency and uniformity of the card flow guiding, and helps to improve the overall shuffling effect.

[0020] Compared with the prior art, the automatic mahjong machine has the following advantages:

[0021] The problem of how to guide the mahjong tiles pushed into the tile inlet to the tile washing disc is solved through the guide tile surface on the guide tile piece. Since the tile washing disc is no longer directly below the tile inlet, the guide tile surface becomes the key guide path for the mahjong tiles from the tile inlet to the tile washing disc. It ensures that the mahjong tiles falling from the tile inlet can be accurately guided to the corresponding tile washing disc, avoids the disordered accumulation or uneven distribution of the mahjong tiles in the tile washing bin, and makes each tile washing disc orderly receive the mahjong tiles for washing operation, thereby guaranteeing the smoothness and efficiency of the entire automatic mahjong machine tile washing process. In addition, the guide tile surface can also avoid the mahjong tiles pushed into the tile inlet from directly falling into the tile washing bin between adjacent tile washing discs, and ensures that all mahjong tiles can fall onto the tile washing disc and be processed by the tile washing disc. It is an important component for realizing efficient operation of the multi-tile washing disc structure. BRIEF DESCRIPTION OF DRAWINGS

[0038] Embodiment one:

[0039] Reference Figures 1 to 5 For the embodiment one of the utility model automatic mahjong machine, the automatic mahjong machine includes host computer, the host computer includes the top opening of the shuffling warehouse 100 and the table top for closing the shuffling warehouse 100 at the top of shuffling warehouse 100, the center of the table top is opened into the tile mouth for pushing mahjong 300 into shuffling warehouse 100, when people entertain, the tile mouth is closed by the dice disc 1000, when a game of mahjong is finished, the control button on the dice disc 1000 is pressed, the dice disc 1000 moves upward, and the tile mouth is left, so that mahjong 300 can be pushed into shuffling warehouse 100 from the tile mouth.

[0040] The bottom surface of the existing shuffling bin 100 has a larger shuffling disc 200. The shuffling disc 200 is driven to rotate relative to the shuffling bin 100 to generate relative motion with the mahjong tiles 300, or a poking rod is added on the shuffling disc 200 to poke the mahjong tiles 300 falling on the shuffling disc 200. This not only can scatter the mahjong tiles 300 to play the role of shuffling, but also can flatten the stacked mahjong tiles 300. Magnets are arranged on the periphery of the shuffling disc 200, and magnets are also arranged in the mahjong tiles 300. When the magnetic poles of the magnets in the mahjong tiles 300 are the same as the magnetic poles of the magnets on the shuffling disc 200, the mahjong tiles 300 will be flipped due to the repulsion of the magnets, thereby realizing the function of flipping the mahjong tiles 300.

[0041] In the present embodiment, at least two adjacent shuffling discs 200 are arranged in the shuffling bin 100, and each shuffling disc 200 can rotate to process the mahjong tiles 300 to scatter the mahjong tiles 300. The shuffling discs 200 are independently arranged and do not interfere with each other. In the present embodiment, the shuffling discs are distributed on the bottom surface of the shuffling bin 100, and all the shuffling discs 200 are located at the same horizontal height to ensure that each shuffling disc 200 can start processing the mahjong tiles 300 at the same time. The main processing process is to ensure that all the mahjong tiles 300 are face up or back up, and to flatten and scatter the stacked mahjong tiles 300 to achieve the purpose of shuffling and making all the mahjong tiles 300 face the same direction. Since the center of the shuffling bin 100 needs to be connected to the dice disc 1000 by a telescopic rod, if the shuffling discs 200 are two, they are symmetrically distributed on both sides of the center of the shuffling bin 100, so that the mahjong tiles 300 can be evenly distributed on the two shuffling discs 200 as much as possible. If the shuffling discs 200 are three, the centers of the three shuffling discs 200 form an equilateral triangle, and the center of the triangle coincides with the center of the shuffling bin 100. Similarly, the mahjong tiles 300 can be evenly distributed on the three shuffling discs 200 as much as possible. The best solution is to arrange four shuffling discs 200 of the same size in the shuffling bin 100, and the centers of the four shuffling discs 200 are located at the four vertices of a square, and the center of the square coincides with the center of the shuffling bin 100. In this way, the distance from the four shuffling discs 200 to the center of the shuffling bin 100 is equal. In addition to making the mahjong tiles 300 evenly distributed on the four shuffling discs 200 as much as possible, it also makes the shuffling bin 100 surrounding the periphery of the four shuffling discs 200 form a square-like shape, which is close to the shape of the main machine. That is, it can make more full use of the space below the main machine, and also make the area of the entire shuffling bin 100 maximum, thereby increasing the area of the mahjong tiles 300, and effectively improving the efficiency of processing the mahjong tiles 300, which can reduce the time for processing the mahjong tiles 300 by 20% compared with the existing single shuffling disc 200.

[0042] Specific shuffling disc 200 includes annular slide surface 210 and circular ring plane 220 arranged around the center of shuffling disc 200, annular slide surface 210 is mainly used to guide mahjong tiles 300 falling on shuffling disc 200 to move to circular ring plane 220 at the outer periphery, annular slide surface 210 can be an inclined arc surface or a plurality of inclined planes arranged around the center of shuffling disc 200, the height of annular slide surface 210 near the center of shuffling disc 200 is greater than the height of annular slide surface 210 away from the center of shuffling disc 200, that is, the height of annular slide surface 210 decreases from the center to the outer periphery, in the process of rotating shuffling disc 200, mahjong tiles 300 can naturally slide along annular slide surface 210 by gravity, so that mahjong tiles 300 move orderly from the center to the edge of shuffling disc 200, improve the flowability of mahjong tiles 300 on the disc surface, and help to improve the efficiency and fluency of shuffling.

[0043] Circular ring plane 220 is connected with the bottom edge of annular slide surface 210, and gaps between annular slide surface 210 and circular ring plane 220 are avoided as much as possible to prevent mahjong tiles 300 from being stuck, preferably, circular ring plane 220 and annular slide surface 210 are smoothly connected, so that mahjong tiles 300 can smoothly enter circular ring plane 220 from annular slide surface 210, circular ring plane 220 provides a relatively stable support plane for mahjong tiles 300, avoids collision or jam of mahjong tiles 300 due to direct falling, plays a buffering and transition role, ensures the stability of the shuffling process, and reduces the possibility of equipment failure and noise generation caused by disordered movement of mahjong tiles 300.

[0044] Further, the shuffling bin 100 is provided with a tile turning magnet 120, and at least one tile turning magnet 120 is arranged on the bottom surface of the shuffling bin 100 below each shuffling disc 200. The tile turning magnet 120 is below the annular plane 220 of the shuffling disc 200, and is as close as possible to the annular plane 220 to maximize the magnetic attraction of the mahjong tiles 300 that have not been turned over correctly. However, the tile turning magnet 120 does not contact the shuffling disc 200 to avoid hindering the normal rotation of the shuffling disc 200. According to the magnetic pole of the tile turning magnet 120 close to the shuffling disc 200, the built-in magnet of the mahjong tile 300 can be controlled to be face up or face down, that is, if the magnet inside the mahjong tile 300 is opposite to the magnetic pole of the tile turning magnet 120, the mahjong tile 300 will be attracted by the tile turning magnet 120, so that the mahjong tile 300 moves relative to the shuffling disc 200, until the mahjong tile 300 is turned over due to collision with other mahjong tiles 300 or the action of the shuffling disc 200, achieving the purpose of all mahjong tiles 300 facing the same direction. When the mahjong tile 300 is being turned over, it relies on the annular plane 220. Compared with setting the tile turning magnet 120 at other positions, which may cause the mahjong tile 300 to be in an unstable state during the turning process, this setting provides a more stable turning fulcrum and movement plane for the mahjong tile 300, making the turning motion more stable and smooth, reducing the risk of affecting the shuffling process due to shaking and deviation of the mahjong tile 300 during the turning process, and helping to improve the tile turning efficiency.

[0045] In order to improve the tile turning efficiency of the mahjong tile 300, a tile turning tab 230 is arranged on the annular plane 220. The tile turning tab 230 rotates with the shuffling disc 200 and abuts against the mahjong tile 300 attracted by the tile turning magnet 120, and pushes the mahjong tile 300 to turn over with the tile turning tab 230 as the fulcrum. The shape of the tile turning tab 230 is not limited, which can be a semicircular arc, a rectangle or a polygon. The height of the tile turning tab 230 is about 1 / 5 to 1 / 4 of the height of the mahjong tile 300, which is more conducive to turning over the mahjong tile 300 when the tile turning tab 230 abuts against and pushes the mahjong tile 300. The tile turning tab 230 provides a clear fulcrum and pushing direction for the turning over of the mahjong tile 300, making the turning over process of the mahjong tile 300 more stable and controllable, ensuring that the mahjong tile 300 can be accurately turned over in the expected way, improving the success rate and consistency of the turning operation, and further improving the shuffling quality and reliability of the automatic mahjong machine. This collaborative design makes full use of the rotating power and magnetic field of the shuffling disc 200, realizes efficient and stable turning function without adding too much complex structure, simplifies the overall structure of the equipment, reduces the manufacturing cost and maintenance difficulty, improves the space utilization and running stability of the equipment, optimizes the performance of the automatic mahjong machine, and provides a better user experience.

[0046] On the basis of the above-mentioned embodiments, the following schemes can be adopted for how to drive the rotating of the shuffling disc 200:

[0047] I. Each shuffling disc 200 is connected with an independent driving motor, that is, each shuffling disc 200 is independently driven to rotate, realizing the accurate control of each shuffling disc 200, and being able to flexibly adjust the rotating speed, rotating direction and other parameters of each shuffling disc 200 according to different shuffling requirements, and having better adaptability when facing complex shuffling tasks or special mahjong tile 300 combination conditions; the driving connection mode of the driving motor and the shuffling disc 200 can adopt that the driving shaft of the driving motor directly drives the rotating shaft at the center of the shuffling disc 200 to rotate, or can adopt that the gear teeth 240 are arranged on the outer periphery of the shuffling disc 200, and the driving motor drives the shuffling disc 200 to rotate through gear transmission or chain transmission.

[0048] II. Two or more shuffling discs 200 share one driving motor to realize the synchronous rotation of the shuffling discs 200, for example, there are four shuffling discs 200 in the present embodiment, and two shuffling discs 200 can be driven to rotate by one driving motor. Specifically, the gear teeth 240 can also be arranged on the outer periphery of the shuffling disc 200, and the driving motor drives the shuffling disc 200 to rotate through gear transmission or chain transmission, for example, the transmission gear 500 is arranged between two adjacent shuffling discs 200 in the present embodiment, and the transmission gear 500 and the gear teeth 240 on the outer periphery of the two shuffling discs 200 are simultaneously engaged, and the driving motor drives the transmission gear 500 to rotate, thereby realizing the simultaneous driving of the two shuffling discs 200 to rotate. Figure 2

[0049] On the basis of the above-mentioned embodiments, for example, Figure 4 , Figure 5 ​As shown, the shuffling disc 200 needs to withstand the impact of the falling mahjong tiles 300 and support the smooth rotation of the shuffling disc 200, therefore, a plurality of roller assembly groups 130 supporting the rotation of the shuffling disc 200 are arranged at the bottom of the shuffling bin 100, in this embodiment, eight roller assembly groups 130 are arranged below each shuffling disc 200, and all the roller assembly groups 130 are distributed on the same circular ring. The roller assembly 130 can adopt the existing disclosed technical solutions, for example, the roller assembly 130 in this embodiment includes a wheel seat and a roller rotatingly arranged on the wheel seat, the wheel seat is fixed at the bottom of the shuffling bin 100, the roller is rotatingly arranged on the wheel seat through a rotating shaft, the roller is in contact with the bottom of the shuffling bin 100 to support the shuffling bin 100 and ensure the smooth rotation of the shuffling bin 100. Compared with other supporting methods, the rolling friction coefficient between the roller and the shuffling disc 200 is smaller. This makes the resistance of the shuffling disc 200 during rotation significantly reduced, and the shuffling disc 200 can run more smoothly, reducing energy loss and component wear caused by excessive friction, which is beneficial to improve the operation efficiency of the equipment and prolong the service life of the roller assembly 130 and the shuffling disc 200, and ensure the stable performance of the automatic mahjong machine during long-term use. The plurality of roller assembly groups 130 can evenly share the weight of the shuffling disc 200, so that the shuffling disc 200 maintains a good balance state during rotation. Compared with single-point support or structures with fewer support points, this design effectively avoids problems such as tilting and shaking of the shuffling disc 200 caused by uneven stress, ensures the smooth movement of the mahjong tiles 300 on the shuffling disc 200, reduces collisions and abnormal stacking of the mahjong tiles 300 caused by instability of the shuffling disc 200, thereby improving the quality and effect of shuffling and providing players with a more reliable gaming experience.

[0050] Further, the shuffling disc 200 is provided with an annular track 250 protruding towards the bottom of the shuffling bin 100, and the roller assembly 130 rolls along the annular track 250. The annular track 250 enables the support force of the roller assembly 130 on the shuffling disc 200 to be evenly distributed along the track, effectively dispersing the stress of the shuffling disc 200 during rotation. This uniform stress distribution significantly reduces local stress concentration compared to single-point or local stress distribution, reducing the risk of deformation, wear and other damage to the shuffling disc 200 caused by long-term uneven stress, thereby prolonging the service life of the shuffling disc 200, reducing the maintenance cost and replacement frequency of the equipment, and improving the overall reliability and economy of the automatic mahjong machine. Moreover, the annular track can be regarded as a reinforcing rib 270 of the shuffling disc 200, supporting the surface of the shuffling disc 200 and improving the overall strength of the shuffling disc 200.

[0051] In addition, the shuffling disc 200 in the embodiment is also provided with a plurality of weight-reducing holes 260. The weight-reducing holes 260 can be arranged on the annular lower sliding surface 210 or the annular flat surface 220, or can cover both the annular lower sliding surface 210 and the annular flat surface 220. The size, shape and distribution of the weight-reducing holes 260 can be selected according to the size of the shuffling disc 200 and the strength of the shuffling disc 200. The weight-reducing holes 260 are arranged to reduce the weight of the shuffling disc 200. When the automatic mahjong machine is running, the lighter shuffling disc 200 means that the energy required for motor driving is reduced, thereby achieving the effect of energy saving and reducing the operation cost of the equipment. At the same time, the reduced weight is also conducive to the stability and dynamic performance of the overall structure of the equipment, reduces unnecessary inertial load, and improves the response speed and operation efficiency of the equipment. On the other hand, the weight-reducing holes 260 also play an important role in reducing noise. In the shuffling process, the collision between the mahjong tiles 300 and the shuffling disc 200 and the rotation and vibration of the shuffling disc 200 are the main noise sources. The presence of the weight-reducing holes 260 changes the vibration mode and energy transmission path of the shuffling disc 200, which can effectively absorb and disperse the energy generated by the collision and vibration, reduce the generation and propagation of noise. Compared with the design without weight-reducing holes 260, the noise level of the automatic mahjong machine during operation can be significantly reduced, creating a relatively quiet and comfortable game environment for players, improving the user experience and satisfaction, and enhancing the competitiveness of the product in the market.

[0052] The shuffling disc 200 is provided with a plurality of reinforcing ribs 270 distributed radially from the center, which provides a strong support structure for the shuffling disc 200. While reducing the weight, the rigidity and anti-deformation ability of the shuffling disc 200 are greatly enhanced, so that it can better cope with the frequent impact and friction of the mahjong tiles 300 during the shuffling process. This structural design ensures that the shuffling disc 200 maintains good geometric shape and mechanical performance during long-term use, improves the reliability and durability of the equipment, reduces the downtime for maintenance due to component damage, and thus ensures the continuous and stable operation of the automatic mahjong machine.

[0053] Further, in order to enhance the strength of the whole shuffling disc 200, reinforcing ribs 270 extend from the center of the shuffling disc 200 to the outer periphery, and a plurality of reinforcing ribs 270 are arranged according to the size, material, thickness and other parameters of the shuffling disc 200, so that the shuffling disc 200 will not deform when impacted by the falling mahjong tiles 300, and will not deform when bearing a large number of mahjong tiles 300 stacked on the shuffling disc 200, ensuring that the shuffling disc 200 can operate stably for a long time. In order to simplify the structure of the shuffling disc 200, the reinforcing ribs 270 in this embodiment are designed to protrude from the upper surface of the shuffling disc 200, and the reinforcing ribs 270 located on the circular ring plane 220 form tile flipping tabs that flip the mahjong tiles 300 attracted by the tile flipping magnet 120 when they are encountered, thereby reducing the number of components on the shuffling disc, and the reinforcing ribs 270 can be integrally formed with the shuffling disc 200, ensuring the strength of the reinforcing ribs 270.

[0054] By changing the previous arrangement of one shuffling disc 200 in the shuffling bin 100 to at least two shuffling discs 200, not only can the area of the shuffling bin 100 be expanded, making full use of the space below the main machine, but also because the shuffling area is expanded, the shuffling efficiency is improved, the number of mahjong tiles 300 in the unit area is reduced, the probability of mahjong tile 300 collision is reduced, and the shuffling noise is also reduced; the number of mahjong tiles 300 in the unit area is also reduced, which reduces the probability of mahjong tile 300 stacking, and each shuffling disc 200 handles a relatively small number of tiles, so the mahjong tiles 300 have more space to tumble and mix in their respective shuffling discs 200, reducing the card jamming caused by excessive stacking of tiles, making the shuffling process smoother.

[0055] Embodiment Two:

[0056] As Figure 1 , Figure 6 , Figure 7As shown, on the basis of the first embodiment, in order to solve the problem of how to guide the mahjong tiles falling into the tile inlet to the tile washing disc. Specifically, since at least two tile washing discs 200 are adopted, there will be gaps between adjacent tile washing discs 200, and if the mahjong tiles 300 fall into these gaps, they will not be processed by the tile washing disc 200. In order to fill these gaps and guide the mahjong tiles 300 that would have fallen into these gaps to the tile washing disc 200, a tile guide 400 is arranged in the tile washing bin 100, and the tile guide 400 is arranged below the tile inlet, so as to better play the role of the tile guide 400. The tile guide 400 is provided with a tile guide surface 410 corresponding to each tile washing disc 200, that is, the tile washing disc 200 has several tile guide surfaces 410 arranged on the tile guide 400, which guide the mahjong tiles 300 falling from the tile inlet to the corresponding tile washing disc 200. The tile guide surface 410 is located between the tile inlet and the tile washing disc 200, and the horizontal height of the side of the tile guide surface 410 close to the tile inlet is greater than the horizontal height of the side of the tile guide surface 410 close to the tile washing disc 200, so that the mahjong tiles 300 can slide along the tile guide surface 410 to the tile washing disc 200 by using the gravity of the mahjong tiles 300. The tile guide surface 410 can be a slope or an arc surface.

[0057] The mahjong tiles 300 not only need to rotate with the tile washing disc 200, but also need to use the gravity of the mahjong tiles 300 to generate relative motion with the tile washing disc 200 when the mahjong tiles 300 hit the side wall around the tile washing disc 200, which can also promote the mahjong tiles 300 to be washed and turned over by the tile turning magnet 120 in the tile washing bin 100. In order to form a side wall around the tile washing disc 200, a blocking surface 110 is arranged in the tile washing bin 100, which is located at the outer periphery of the side of the tile washing disc 200 away from the tile inlet, and the tile guide surface 410 is located at the outer periphery of the side of the tile washing disc 200 close to the tile inlet. The blocking surface 110 and the tile guide surface 410 jointly form the side wall of the tile washing disc 200 or form part of the side wall. When the mahjong tiles 300 are subjected to various forces such as centrifugal force of the tile washing disc 200 and gravity of the mahjong tiles 300, the blocking surface 110 and the tile guide surface 410 can prevent the mahjong tiles 300 from sliding or moving to other areas due to the force, and ensure that the mahjong tiles 300 always perform the tile washing action within the specified tile washing disc 200. The second separation ridge 111 is formed between adjacent blocking surfaces 110, which can avoid the mahjong tiles 300 from staying, guide the mahjong tiles 300 to the blocking surface 110, and enter the tile washing disc 200 under the influence of the blocking surface 110. The horizontal height of the second separation ridge 111 is generally lower than the horizontal height of the tile washing disc 200, which ensures that the mahjong tiles 300 can be completely guided, and avoids the mahjong tiles 300 from being stuck between the second separation ridge 111 and the tile washing disc 200.

[0058] The blocking surface 110 and the guide piece 400 can form a complete closed ring to separate each shuffling disc 200 into an independent area, or the blocking surface 110 and the guide piece 400 can form an open ring to allow each shuffling disc 200 to communicate with each other, and the mahjong tiles 300 can enter another adjacent shuffling disc 200 from one shuffling disc 200. Specifically:

[0059] The blocking surface 110 and the guide piece 400 form a closed ring to separate the shuffling disc 200, so that each shuffling disc 200 is in a relatively independent and stable space environment during operation. During the shuffling process, the rotation of each shuffling disc 200 and the movement of the mahjong tiles 300 do not interfere with each other, avoiding problems such as mahjong tiles 300 disorder and increased collision caused by mutual influence between adjacent shuffling discs 200, ensuring that each shuffling disc 200 can efficiently shuffle the mahjong tiles 300 in the expected manner, thereby improving the shuffling stability and reliability of the entire automatic mahjong machine. Since it is a closed ring, the mahjong tiles 300 entering the shuffling disc 200 will have more opportunities to be scattered and turned over.

[0060] The guide tile surface 410 can be extended to the blocking surface 110 and connected to the blocking surface 110, or a partition 430 can be provided to connect the blocking surface 110 and the guide tile surface 410. Since the partition 430 only has a blocking function, the partition 430 can be provided in a detachable form to facilitate replacement after damage or deformation. When the partition 430 is provided in a split structure, it can be inserted into the blocking surface 110 through a clamping groove, and a convex rib can also be provided on the guide piece 400 to cooperate with the clamping groove for insertion, or other detachable connection methods can be used to connect the partition 430 with the blocking surface 110 and the guide piece main body. The partition 430 can also be integrally provided with the guide piece main body to facilitate manufacturing and installation. The guide piece 400 is provided with a partition 430 connecting the blocking surface 110 and the guide tile surface 410, so that the guide piece 400, the blocking surface 110 and the guide tile surface 410 form an organic whole structure, which better separates the shuffling disc 200. During the frequent shuffling operation of the automatic mahjong machine, this connection structure can better withstand the impact and vibration of the mahjong tiles 300 and various stresses generated by the operation of the machine, reducing the risk of relative displacement and loosening between parts, thereby improving the stability and reliability of the entire structure and ensuring the continuous and effective function of the guide and blocking functions during long-term use.

[0061] Further, the bottom edge of the guide plate surface 410 and the bottom surface of the partition 430 are both lower than the contact surface between the shuffler disc 200 and the mahjong tiles 300. The mahjong tiles 300 are more likely to slide along the guide plate surface 410 to the corresponding shuffler disc 200 under the action of gravity, avoiding the mahjong tiles 300 being stuck between the bottom edge of the guide plate surface 410 and the shuffler disc 200, or the mahjong tiles 300 being stuck or accumulated due to the bottom surface being too high, so that the guiding process of the mahjong tiles 300 is more smooth, and the shuffling efficiency of the entire automatic mahjong machine is improved.

[0062] The shuffler discs 200 are connected, and the shuffler disc 200 has at least three, the blocking surface 110 and the guide plate surface 410 form an annular with a gap, and the gap connects adjacent shuffler discs 200. This connection structure can make the mahjong tiles 300 adjust and redistribute between different shuffler discs 200 according to actual conditions. If there are too many mahjong tiles 300 in a shuffler disc 200, the mahjong tiles 300 can overflow from the gap to the adjacent shuffler disc 200, so as to speed up the shuffling speed, avoid the situation that there are too many or too few mahjong tiles 300 on some shuffler discs 200, further optimize the distribution balance of the mahjong tiles 300 on multiple shuffler discs 200, and improve the shuffling efficiency.

[0063] On the basis of the above embodiment, the first partition ridge 420 is arranged between the adjacent guide plate surfaces 410 on the guide plate 400. When the mahjong tiles 300 encounter the first partition ridge 420, the mahjong tiles 300 can quickly incline to one side of the guide plate surface 410, so as to speed up the guiding speed of the mahjong tiles 300 and avoid the mahjong tiles 300 being stuck between the two guide plate surfaces 410. The first partition ridge 420 can also extend in the direction of the blocking surface 110 to form the partition 430. Further, the bottom end of the first partition ridge 420 is lower than the horizontal height of the shuffler disc 200, so as to prevent the mahjong tiles 300 from being stuck in the gap between the first partition ridge 420 and the shuffler disc 200.

[0064] For the guide card surface 410, the height gradually decreases and the width gradually increases from the center of the shuffling bin 100 to the edge of the corresponding shuffling disc 200. The height gradually decreases and the width gradually increases from the center of the shuffling bin 100 to the edge of the corresponding shuffling disc 200 of the guide card surface 410, which conforms to the movement law of mahjong tiles 300 under the action of gravity. The gradual decrease in height provides a natural sliding slope for mahjong tiles 300, enabling them to move more smoothly from the vicinity of the tile inlet to the shuffling disc 200; the gradual increase in width provides a wider accommodation space for mahjong tiles 300, avoiding congestion or poor sliding of mahjong tiles 300 due to narrow space during the guiding process. Thus, the guiding efficiency of mahjong tiles 300 from the tile inlet to the shuffling disc 200 is effectively improved, the residence time of mahjong tiles 300 on the guide card surface 410 is reduced, and the shuffling process is accelerated. This design enables mahjong tiles 300 to be more evenly distributed to each shuffling disc 200. Because of the special shape of the guide card surface 410, mahjong tiles 300 can be guided to slide in an orderly manner, avoiding the accumulation or uneven distribution of mahjong tiles 300 in a certain area, so that each shuffling disc 200 is in a relatively balanced state when initially receiving mahjong tiles 300. This is conducive to subsequent shuffling process, enabling each shuffling disc 200 to operate on approximately the same number and distribution state of mahjong tiles 300, thereby improving the shuffling uniformity of the entire automatic mahjong machine and enhancing the shuffling effect and quality, providing a more fair game environment for players.

[0065] Further, the bottom edge of the guide card surface 410 is arc-shaped and matches the curvature of the outer circle of the shuffling disc 200, trying to keep the distance between the guide card surface 410 and the shuffling disc 200 equal and the gap between the guide card surface 410 and the shuffling disc 200 matched, thereby preventing the guide card surface 410 from hindering the rotation of the shuffling disc 200. However, the gap should not be too large to avoid mahjong tiles 300 being stuck in the gap, ensuring that mahjong tiles 300 can smoothly slide from the guide card surface 410 to the shuffling disc 200, maintaining the smoothness of the shuffling process, avoiding equipment failure and shuffling interruption caused by card jamming, and improving the running stability and reliability of the automatic mahjong machine.

[0066] On the basis of the above embodiments, the shuffling discs 200 are evenly distributed on a circular track with the center of the shuffling bin 100 as the center, the guide card piece 400 is located at the center of the shuffling bin 100, and the tile inlet is located directly above the guide card piece 400. This layout enables mahjong tiles 300 to be dispersed and guided to the surrounding shuffling discs 200 in a more balanced manner after falling from the tile inlet. Compared with a chaotic layout, this design makes full use of the space of the shuffling bin 100, reduces the mutual interference and collision of mahjong tiles 300 during the guiding process, improves the efficiency and uniformity of the card flow guiding, and helps to improve the overall shuffling effect.

[0067] Embodiment Three

[0068] The embodiment can be implemented on the basis of Embodiment One or Two, or on other types of automatic mahjong machines.

[0069] As Figure 2 , Figure 8 Embodiment Three of the automatic mahjong machine is shown in the figure. The main machine of the automatic mahjong machine of the embodiment is further provided with a ring-shaped main track 600 and at least one set of tile feeding assembly 700 that picks up mahjong tiles 300 from the shuffling disc 200. Each set of tile feeding assembly 700 is in communication with the main track 600 through a sub-track 800, and the mahjong tiles 300 picked up by the tile feeding assembly 700 are transported from the sub-track 800 to the main track 600. The main track 600 is provided with a conveying mechanism 610 that drives the mahjong tiles 300 to move along the main track 600. When a set of tile arranging mechanism is full of mahjong tiles 300, the excess mahjong tiles 300 will also be driven to the next tile arranging mechanism, and the mahjong tiles 300 will not be returned to the shuffling disc 200. Therefore, as long as the mahjong tiles 300 washed by the shuffling disc 200 are picked up by the tile feeding assembly 700, the shuffling disc 200 will complete the shuffling work, and the shuffling time is shortened. In addition, the ring-shaped main track 600 not only can transport the mahjong tiles 300 to each set of tile arranging mechanism, but also can serve as a mahjong tile storage component. When the speed of the mahjong tiles 300 fed into the main track 600 is greater than the tile arranging speed of the tile arranging mechanism, the main track 600 can also serve as a storage component, ensuring that the tile feeding assembly 700 and the shuffling disc 200 can operate continuously and complete the shuffling work as soon as possible, and the shuffling noise generation time is shortened. Specifically, the main track 600 can be circular or circular quadrilateral, so as to avoid forming a right angle or an angle that is too small, and to prevent the mahjong tiles 300 from being stuck in the main track 600. In the embodiment, the main track 600 is located above the shuffling bin 100, so as to avoid affecting the arrangement of the shuffling bin 100, and the main track 600 can be arranged along the edge of the shuffling bin 100, so as to maximize the circumference of the main track 600 and enable the main track 600 to carry more mahjong tiles 300.

[0070] Further, the width of the main track 600 and the sub-track 800 is adapted to the width of a single mahjong tile 300, that is, the width of the main track 600 and the sub-track 800 is consistent with the width of a single mahjong tile 300, and can be slightly larger than the width of the mahjong tile 300, so as to ensure that the mahjong tiles 300 will not be stuck in the main track 600 and the sub-track 800, and the mahjong tiles 300 can move smoothly along the main track 600 and the sub-track 800. The mahjong tiles 300 will move in a column in the main track 600, so as to avoid disordered arrangement of the mahjong tiles 300 in the main track 600 and the sub-track 800, and the tile arranging assembly can orderly grasp the mahjong tiles 300 in the main track 600.

[0071] In addition, in order to facilitate the mahjong 300 in the sub-track 800 to smoothly enter the main track 600, the angle between the conveying direction of the mahjong 300 in the sub-track 800 and the conveying direction of the mahjong 300 in the main track 600 is an acute angle, that is, the mahjong 300 in the sub-track 800 has a component speed in the movement direction of the mahjong 300 in the main track 600. After part of the mahjong 300 in the sub-track 800 is located in the main track 600, the mahjong 300 in the main track 600 can be pushed by the conveying mechanism 610 in the main track 600 to completely enter the main track 600.

[0072] The intersection of the main track 600 and the sub-track 800 is provided with a single mahjong passing assembly 900. The single mahjong passing assembly 900 controls the passing of the mahjong 300 at the intersection of the main track 600 and the sub-track 800, so that only the mahjong 300 in the main track 600 or the sub-track 800 can pass the intersection of the two tracks at the same time, avoiding the situation that the mahjong 300 in the main track 600 and the sub-track 800 is located at the intersection of the two tracks at the same time, causing two mahjong 300 coming from different directions to be stuck in the track.

[0073] The single mahjong passing assembly 900 includes but is not limited to the following structure:

[0074] The first one is a pure mechanical form. The single mahjong passing assembly 900 includes a control member 910 swingingly arranged at the intersection of the main track 600 and the sub-track 800. When the mahjong 300 in the main track 600 passes the control member 910, the control member 910 is pushed to swing towards the sub-track 800, that is, at least part of the control member 910 is located in the sub-track 800. Since the width of the sub-track 800 is equal to the width of the mahjong 300, the control member 910 located in the sub-track 800 will block the movement of the mahjong 300 in the sub-track 800. After the mahjong 300 in the main track 600 passes, the mahjong 300 in the sub-track 800 can push the control member 910 to enter the main track 600. Similarly, if the mahjong 300 in the sub-track 800 reaches the intersection of the main track 600 and the sub-track 800 first, the mahjong 300 in the sub-track 800 will push the control member 910 to swing towards the main track 600, and at least part of the control member 910 will be located in the main track 600. Since the width of the main track 600 is equal to the width of the mahjong 300, the control member 910 partially invading the main track 600 will block the movement of the mahjong 300 in the main track 600. After the mahjong 300 in the sub-track 800 enters the main track 600, the mahjong 300 in the main track 600 can push the control member 910 to continue to move.

[0075] In the embodiment, the control member 910 comprises a transition part 911 and first and second blocking surfaces 912 and 913 respectively located on both sides of the transition part 911. The entire transition part 911 can be shaped as a triangular prism, one corner of which forms the transition part 911, which is connected to the intersection of the main track 600 and the sub-track 800 through a rotating shaft, and the rotating member is close to the upstream side of the intersection of the main track 600 and the sub-track 800, so as to timely block the mahjong 300 in the other track. The first blocking surface 912 blocks the mahjong 300 in the main track 600 when the mahjong 300 passes through the sub-track 800, and the second blocking surface 913 blocks the mahjong 300 in the sub-track 800 when the mahjong 300 passes through the main track 600. Since the entire transition part 911 is shaped as a triangular prism, the first and second blocking surfaces 912 and 913 are both a side of the transition part 911. After the mahjong 300 in the main track 600 passes through, the mahjong 300 in the sub-track 800 can smoothly slide along the second blocking surface 913, smoothly pushing the control member 910 away, avoiding the control member 910 from being stuck with the mahjong 300 in the sub-track 800. Similarly, the first blocking surface 912 also has a similar effect. Since the swinging control member 910 controls the opening and closing of the main track 600 and the sub-track 800 through a purely mechanical way, and the control member 910 has a simple structure and high reliability, it can meet the requirements of the high-speed and smooth passing of the mahjong 300.

[0076] The second is to use electronic control. The single mahjong passing assembly 900 comprises a sensor and a blocking member controlled by the sensor. At the intersection of the main track 600 and the sub-track 800, both the main track 600 and the sub-track 800 are provided with a sensor and a blocking member. The blocking member can be in a linear motion form, that is, after being triggered, the blocking member will extend into the corresponding track, and when not triggered, it will be located outside the track without affecting the movement of the mahjong 300 in the track. The blocking member can also be in a swinging form, that is, after being triggered, the blocking member will rotate along the axis into the corresponding track, and after the mahjong 300 in the other track passes through, it will swing out of the current track to allow the mahjong 300 to pass through. The sensor can be a Hall sensor that discriminates whether the mahjong 300 is to pass through the intersection of the two tracks by sensing the magnetic field of the mahjong 300, or an infrared sensor, etc., which is triggered when the mahjong 300 passes through. The electronic sensor has high sensitivity, can conveniently control the opening and closing of the main track 600 and the sub-track 800, and can also be linked with a counter and other sensors to control the action of the blocking member while counting.

[0077] When there is only one shuffling disc 200 in the shuffling compartment 100, the more the number of the tile feeding assemblies 700, the faster the mahjong tiles 300 are picked up from the shuffling disc 200 into the main track 600. Of course, the shuffling efficiency of the shuffling disc 200 should be considered, and the number of the tile feeding assemblies 700 should be reasonably controlled. All the tile feeding assemblies 700 can be evenly distributed in the main machine to avoid the accumulation of mahjong tiles 300 in a certain section of the main track 600. When there are multiple shuffling discs 200 in the shuffling compartment 100, the number of the tile feeding assemblies 700 is equal to the number of the shuffling discs 200. For example, in the first embodiment, there are four shuffling discs 200, and each shuffling disc 200 corresponds to a group of tile feeding assemblies 700, which can ensure that the well-shuffled mahjong tiles 300 on each shuffling disc 200 can be picked up into the main track 600. Even if there are too many mahjong tiles 300 on a certain shuffling disc 200, it can also ensure that all the tile feeding assemblies 700 can pick up enough mahjong tiles 300 to complete the tile feeding work. The tile feeding assembly 700 and the tile feeding assembly in the present embodiment can refer to the structure in the prior art. The tile feeding assembly 700 includes a roller with a magnet, a motor for driving the roller to rotate, and a support for supporting the roller to roll. The roller attracts the well-shuffled mahjong tiles 300 on the shuffling disc 200 through the magnet and carries them to the sub-track 800 to be transported to the main track 600.

[0078] On the basis of the above-mentioned embodiments, the conveying mechanism 610 includes but is not limited to the following structures:

[0079] The first is that when there are at least two groups of tile feeding assemblies 700, such as four groups of tile feeding assemblies 700, which are respectively the first, second, third, and fourth groups of tile feeding assemblies in the clockwise direction. The number of the conveying mechanisms 610 is equal to the number of the tile feeding assemblies 700, that is, there are four conveying mechanisms 610 and they have the same number as the tile feeding assemblies 700. The conveying mechanism 610 extends from the tile inlet of the sub-track 800 to the tile outlet of the adjacent sub-track 800 in the conveying direction of the mahjong tiles 300 on the main track 600, that is, the conveying mechanism 610 carries the mahjong tiles 300 from the tile inlet of the first sub-track 800 into the main track 600 and continuously conveys them to the position of the main track 600 at the tile outlet of the second sub-track 800. The four conveying mechanisms 610 arranged in this way will cover the entire main track 600 and sub-track 800, which can ensure that the mahjong tiles 300 in the sub-track 800 can smoothly enter the main track 600. The conveying mechanism 610 can adopt a first conveying belt or a conveying roller to ensure the smooth movement of the mahjong tiles 300. In the present embodiment, the conveying mechanism 610 adopts a first conveying belt. In Figure 1 、 Figure 2 and Figure 4 do not show the conveying belt, but only show the conveying wheel for driving the conveying belt to rotate.

[0080] Second, the conveying mechanism 610 is arranged along the main track 600, that is, the conveying mechanism 610 is only responsible for the movement of the mahjong 300 on the main track 600, and the pushing wheel 810 is arranged on each sub-track, and the pushing wheel 810 is responsible for pushing the mahjong 300 on the sub-track into the main track. The structure and number of the conveying mechanism 610 are not affected by the number of the sub-track 800. When the sub-track 800 is increased, the pushing wheel 810 needs to be arranged on the corresponding sub-track 800, so that the arrangement mode is more flexible. The conveying mechanism 610 can also adopt the structure of the second conveying belt or the conveying roller.

[0081] Through the structure of the automatic mahjong machine, the shuffling disc 200 can only shuffle the mahjong 300 once, and will not accept the mahjong 300 returned from the tile arranging assembly, so that the running time of the shuffling disc 200 can be shortened, the time for generating noise during shuffling can be reduced, and the experience of a user can be improved. In the embodiment, the main track 600 is annular, and the mahjong 300 will move in the annular main track 600 until being picked up by the tile arranging assembly. The main track 600 can not only convey the mahjong 300 to each tile arranging mechanism, but also can be used as a mahjong 300 storage component. The shuffling disc 200, the tile feeding assembly 700 and the tile arranging assembly can run at the respective optimal speeds without being restricted by each other, and the respective work can be completed as soon as possible.

[0082] The above only describes specific embodiments of the utility model, but the technical features of the utility model are not limited to this. Any person skilled in the art can make changes or modifications in the field of the utility model, and the changes or modifications are covered in the patent range of the utility model.
