Description

Technical Field

[0001] This utility model relates to the field of mahjong machine technology, specifically to an automatic mahjong machine. Background Technology

[0002] Mahjong is a popular intellectual game. After each game, the tiles need to be shuffled, a process that is tedious and time-consuming. Therefore, a new type of mahjong machine capable of automatic shuffling has been developed. Existing automatic mahjong machines include a main unit with a shuffling chamber. A shuffling disc is located in the center of the shuffling chamber. Mahjong tiles pushed in from the tabletop's inlet fall into the shuffling chamber. The rotation of the shuffling disc not only shuffles the tiles but also flips them so that all tiles face up, making them easier for the tile-feeding component to capture and arrange.

[0003] The existing shuffling chamber has only one shuffling plate, on which all the mahjong tiles are stacked, resulting in low shuffling efficiency and relatively high noise. Due to the limitations of motor power and other factors, the diameter of a single shuffling plate cannot be made too large, and the size of the shuffling chamber is determined by the size of the shuffling plate. Therefore, the space under the entire main unit cannot be fully utilized, reducing space utilization. Utility Model Content

[0004] The purpose of this invention is to provide an automatic mahjong machine that can effectively solve the problem of low efficiency of existing shuffling machines.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] An automatic mahjong machine includes a main unit, which includes a shuffling chamber and a tabletop located above the shuffling chamber. The tabletop has an inlet for pushing mahjong tiles into the shuffling chamber. The shuffling chamber has at least two adjacent shuffling trays, which process the mahjong tiles that fall into the shuffling chamber from the inlet.

[0007] In the aforementioned automatic mahjong machine, each shuffling disc is connected to an independent drive motor; alternatively, at least two shuffling discs are driven synchronously by a single drive motor. Two driving methods are provided. Connecting each shuffling disc to an independent drive motor allows for precise control of each disc, enabling flexible adjustment of parameters such as speed and direction according to different shuffling needs. This provides better adaptability to complex shuffling tasks or special mahjong tile combinations. The method of driving at least two shuffling discs synchronously by a single drive motor is relatively simple, reducing equipment costs and the complexity of the control system. In scenarios where shuffling accuracy requirements are not extremely high, it meets basic shuffling function needs and offers high cost-effectiveness, providing manufacturers and users with diverse options.

[0008] In the aforementioned automatic mahjong machine, the shuffling disc has teeth on its outer periphery, and the shuffling disc is connected to the drive motor via gear transmission or chain transmission. The shuffling disc's outer periphery has teeth, and it is connected to the drive motor via gear transmission or chain transmission. Compared to other transmission methods, this structure provides more stable and reliable power transmission. Gear transmission has advantages such as precise transmission ratio, high efficiency, and strong load-bearing capacity, ensuring that the shuffling disc rotates stably at a predetermined speed and torque, guaranteeing the consistency and accuracy of the shuffling process. Chain transmission has a certain buffering and vibration absorption capacity, which can adapt to the impact load during the shuffling process, reducing damage to the transmission system due to instantaneous overload. At the same time, its structure is relatively simple, easy to install and maintain, effectively improving the stability and reliability of the equipment operation.

[0009] In the aforementioned automatic mahjong machine, the bottom of the shuffling chamber is equipped with multiple sets of roller assemblies supporting the rotation of the shuffling disc. Compared to other support methods, the rolling friction coefficient between the rollers and the shuffling disc is lower. This significantly reduces the resistance experienced by the shuffling disc during rotation, allowing for smoother operation, reducing energy loss and component wear caused by excessive friction. This improves the machine's operating efficiency and extends the service life of the roller assemblies and the shuffling disc, ensuring stable performance of the automatic mahjong machine over long-term use. The multiple sets of roller assemblies evenly distribute the weight of the shuffling disc, maintaining good balance during rotation. Compared to structures with single-point support or fewer support points, this design effectively avoids problems such as tilting and wobbling of the shuffling disc due to uneven force distribution, ensuring stable movement of the mahjong tiles on the shuffling disc. It reduces collisions and abnormal stacking of mahjong tiles caused by disc instability, thereby improving the quality and effect of shuffling and providing players with a more reliable gaming experience.

[0010] In the aforementioned automatic mahjong machine, the shuffling tray is provided with an annular track protruding towards the bottom of the shuffling chamber, and the roller assembly rolls along the annular track. The annular track allows the supporting force of the roller assembly on the shuffling tray to be evenly distributed along the track, effectively dispersing the force on the shuffling tray during rotation. Compared to single-point or localized force, this uniform force distribution significantly reduces localized stress concentration, minimizing the risk of deformation, wear, and other damage to the shuffling tray caused by long-term uneven force distribution. This extends the service life of the shuffling tray, reduces equipment maintenance costs and replacement frequency, and improves the overall reliability and economy of the automatic mahjong machine. Furthermore, the annular track also supports the surface of the shuffling tray, increasing its overall strength.

[0011] In the aforementioned automatic mahjong machine, the shuffling disc includes an annular sliding surface and a circular plane surrounding its center. The height of the sliding surface near the center of the shuffling disc is greater than its height away from the center. The circular plane surrounds the outer periphery of the sliding surface. The sliding surface forms a certain slope, allowing the mahjong tiles to slide naturally along it under gravity during the rotation of the shuffling disc. This orderly movement of the tiles from the center to the edge of the disc improves their fluidity and enhances shuffling efficiency and smoothness. The circular plane provides a relatively stable support surface when the mahjong tiles slide from the sliding surface to the circular plane, preventing collisions or jamming caused by direct falls. This buffering and transitioning effect ensures the smoothness of the shuffling process and reduces potential equipment malfunctions and noise caused by disordered tile movement.

[0012] In the aforementioned automatic mahjong machine, a flipping magnet is installed in the shuffling chamber below the annular plane. Under the action of the flipping magnet below the annular plane, the mahjong tiles are attracted and flipped, relying on the annular plane for support. Compared to placing the flipping magnet in other locations, which might cause the mahjong tiles to be unstable during the flipping process, this arrangement provides a more stable flipping fulcrum and movement plane for the mahjong tiles, making the flipping action smoother and more stable. This reduces the risk of the mahjong tiles shaking or shifting during the flipping process, affecting the shuffling process and helping to improve flipping efficiency.

[0013] In the aforementioned automatic mahjong machine, a flipping lever is provided on the circular plane. As the shuffling disc rotates, the flipping lever contacts the mahjong tiles attracted by the flipping magnet, pushing the tiles to flip around the lever as a fulcrum. The flipping lever provides a clear fulcrum and direction of movement for the mahjong tiles, making the flipping process more stable and controllable. This ensures the tiles are flipped accurately as expected, improving the success rate and consistency of the flipping operation, thereby enhancing the shuffling quality and reliability of the automatic mahjong machine. This collaborative design fully utilizes the rotational power and magnetic field of the shuffling disc, achieving a highly efficient and stable flipping function without adding excessive complexity. Compared to some independently designed and complex flipping devices, this not only simplifies the overall structure of the equipment, reducing manufacturing costs and maintenance difficulty, but also improves the space utilization and operational stability of the equipment, resulting in optimized performance and a better user experience for the automatic mahjong machine.

[0014] In the aforementioned automatic mahjong machine, the shuffling disc has several weight-reducing holes, and multiple reinforcing ribs are radially distributed from the center. These weight-reducing holes effectively reduce the disc's weight. During operation, a lighter shuffling disc means less energy is required for motor drive, resulting in energy savings and reduced operating costs. Simultaneously, the reduced weight also contributes to the overall structural stability and dynamic performance of the equipment, reducing unnecessary inertial loads and improving response speed and operating efficiency. The radially distributed reinforcing ribs provide a strong support structure for the shuffling disc. While reducing weight, this significantly enhances the rigidity and deformation resistance of the shuffling disc, enabling it to better withstand the frequent impacts and friction of the mahjong tiles during shuffling. This structural design ensures that the shuffling disc maintains good geometry and mechanical properties during long-term use, improving the reliability and durability of the equipment, reducing downtime due to component damage, and thus guaranteeing the continuous and stable operation of the automatic mahjong machine. In addition to reducing the weight of the shuffling disc, the weight-reducing holes also play a crucial role in reducing noise. During the shuffling process, the collision between the mahjong tiles and the shuffling disc, as well as the rotational vibration of the shuffling disc, are the main sources of noise. The presence of weight-reducing holes alters the vibration modes and energy transfer paths of the shuffling disc, effectively absorbing and dispersing the energy generated by collisions and vibrations, thus reducing noise generation and propagation. Compared to a design without weight-reducing holes, this significantly reduces the noise level of the automatic mahjong machine during operation, creating a relatively quiet and comfortable gaming environment for players, improving user experience and satisfaction, and enhancing the product's competitiveness in the market.

[0015] In the aforementioned automatic mahjong machine, the reinforcing rib extends from the center of the shuffling disc to its outer periphery. The reinforcing rib protrudes from the upper surface of the shuffling disc, and the reinforcing rib located on the annular plane forms the flipping lever. The reinforcing rib extending from the center to the outer periphery of the shuffling disc strengthens the entire shuffling disc, preventing deformation when impacted by falling mahjong tiles. Furthermore, the reinforcing rib protruding from the annular plane also functions as a flipping lever, turning over the mahjong tiles held by the flipping magnet.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] The shuffling chamber features at least two adjacent shuffling trays, addressing the inefficiency of existing shuffling trays. Multiple shuffling trays within the chamber fully utilize the space at the bottom of the main unit, maximizing the chamber's area and distributing the mahjong tiles as evenly as possible, reducing the probability of tile stacking. Each tray handles a relatively smaller number of tiles, allowing for more space for tumbling and mixing, minimizing clogging caused by excessive tile accumulation. This makes the shuffling process smoother and ensures more even and thorough distribution and movement of the tiles within the chamber, avoiding the incomplete or uneven shuffling that can occur with single-pan shuffling. This results in more random tile combinations, enhancing the game's fairness and enjoyment. Furthermore, at least two adjacent shuffling trays allow stacked tiles to be laid flat on the trays quickly, reducing the probability of tile collisions, minimizing shuffling noise, and making better use of the space at the bottom of the main unit. Furthermore, employing at least two shuffling discs, with each disc having a smaller diameter than those in existing technologies, allows the mahjong tiles to move more quickly to the edge of the disc for flipping or being captured by the feeding assembly. The simultaneous processing of tiles by multiple discs further accelerates the shuffling process. This multi-disc layout also helps to distribute mechanical stress and load during the shuffling process, reducing excessive wear and fatigue of individual components compared to a single-disc structure. This contributes to extending the equipment's lifespan and enhancing the stability and reliability of the automatic mahjong machine during long-term use. Attached Figure Description

Detailed Implementation

[0028] An automatic mahjong machine includes a main unit, which includes a shuffling chamber 100 and a tabletop located above the shuffling chamber 100. The tabletop has an inlet for pushing mahjong tiles 300 into the shuffling chamber 100. The shuffling chamber 100 is provided with at least two adjacent shuffling trays 200, which process the mahjong tiles 300 that fall into the shuffling chamber 100 from the inlet.

[0029] At least two adjacent shuffling discs 200 are installed within the shuffling chamber 100 to address the low efficiency of existing shuffling discs 200. By placing multiple shuffling discs 200 within the shuffling chamber 100, the space at the bottom of the main unit can be fully utilized to arrange a reasonable number of discs 200, maximizing the area of ​​the shuffling chamber 100. This allows the mahjong tiles 300 to be dispersed as much as possible, reducing the probability of tile stacking. Each shuffling disc 200 handles a relatively small number of tiles, giving the mahjong tiles 300 more ample space to tumble and mix within their respective discs, reducing the risk of clogging due to excessive tile stacking. This makes the shuffling process smoother and ensures a more even and thorough distribution and movement of the mahjong tiles 300 within the shuffling chamber 100. It avoids the problem of incomplete or uneven shuffling that may occur with single-disc shuffling, resulting in more random combinations of the mahjong tiles 300 and enhancing the fairness and fun of the game. Furthermore, the presence of at least two adjacent shuffling discs 200 allows stacked mahjong tiles 300 to be laid flat on the discs 200 as quickly as possible, reducing the probability of collisions and lowering the shuffling noise. It also makes better use of the space at the bottom of the main unit. Additionally, with at least two shuffling discs 200, the diameter of each disc is smaller than that of existing single-disc shuffling discs. This allows the mahjong tiles 300 to move to the edge of the disc 200 more quickly for flipping or being captured by the feeding component. The simultaneous processing of mahjong tiles 300 by multiple discs further accelerates the shuffling speed. The layout of multiple shuffling discs 200 can also distribute the mechanical stress and load during the shuffling process to a certain extent. Compared to a single-disc structure, this reduces excessive wear and fatigue of individual components, helping to extend the service life of the equipment and enhance the stability and reliability of the automatic mahjong machine during long-term use.

[0034] Example 1:

[0035] See Figures 1 to 5 This is one embodiment of the automatic mahjong machine of the present invention. The automatic mahjong machine includes a main unit, which includes a shuffling chamber 100 with an opening at the top and a tabletop located on top of the shuffling chamber 100 to close it. At the center of the tabletop is an inlet for pushing mahjong tiles 300 into the shuffling chamber 100. When people are playing, the inlet is closed by a dice plate 1000. After a game of mahjong ends, by pressing the control button on the dice plate 1000, the dice plate 1000 moves upward, opening up the inlet, so that the mahjong tiles 300 can be pushed into the shuffling chamber 100 from the inlet. The shuffling chamber 100 is equipped with a shuffling plate 200, which is mainly used to process mahjong tiles 300. The processing includes randomly scattering the mahjong tiles 300 and flipping them over so that all the mahjong tiles 300 are face up or face down, so that they can be picked up and stacked by the tile delivery component 700 located in the shuffling chamber 100.

[0036] The existing shuffling chamber 100 has a large shuffling plate 200 on its bottom surface. The shuffling plate 200 is driven by a motor to rotate relative to the shuffling chamber 100, creating relative movement with the mahjong tiles 300. Alternatively, a lever can be added to the shuffling plate 200 to move the mahjong tiles 300 that have fallen onto it. This not only disperses the mahjong tiles 300, thus shuffling them, but also flattens stacked mahjong tiles 300. Magnets are located around the periphery of the shuffling plate 200, and magnets are also located inside the mahjong tiles 300. When the magnetic poles of the magnets inside the mahjong tiles 300 are the same as the magnetic poles of the magnets on the shuffling plate 200, the mahjong tiles 300 will flip due to the repulsive force of the magnets, thus achieving the effect of flipping the mahjong tiles 300.

[0037] In this embodiment, the shuffling chamber 100 is provided with at least two adjacent shuffling discs 200. Each shuffling disc 200 can rotate to process the mahjong tiles 300, scattering them. The term "adjacent shuffling discs 200" means that each shuffling disc 200 is set independently and does not interfere with each other. In this embodiment, the shuffling discs are distributed on the bottom surface of the shuffling chamber 100, and all 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 steps are to ensure that all mahjong tiles 300 are face up or face down, to lay the stacked mahjong tiles 300 flat, and to scatter the mahjong tiles 300, thereby achieving the purpose of shuffling and aligning all mahjong tiles 300. Since the center of the shuffling chamber 100 needs to be connected to the dice disk 1000 via a telescopic rod, if there are two shuffling disks 200, they would be symmetrically distributed on both sides of the center of the shuffling chamber 100, allowing the mahjong tiles 300 to fall as evenly as possible on the two shuffling disks 200. If there are three shuffling disks 200, the centers of the three shuffling disks 200 would form an equilateral triangle with the center of the triangle coinciding with the center of the shuffling chamber 100, again to ensure the mahjong tiles 300 fall as evenly as possible on the three shuffling disks 200. The optimal solution is to set four shuffling disks 200 of the same size within the shuffling chamber 100, with the centers of the four shuffling disks 200 located at the four vertices of a square, and the center of the square coinciding with the center of the shuffling chamber 100. With the four shuffling discs 200 equidistant from the center of the shuffling chamber 100, the mahjong tiles 300 can be distributed as evenly as possible across the four shuffling discs 200. This also allows the shuffling chamber 100 surrounding the four shuffling discs 200 to form a near-square shape, which is similar to the shape of the main unit. This means that the space at the bottom of the main unit can be utilized more fully, and the area of ​​the entire shuffling chamber 100 can be maximized, thereby increasing the area where the mahjong tiles 300 can be laid flat. As a result, the efficiency of processing mahjong tiles 300 will be effectively improved, reducing the processing time by 20% compared to the existing single shuffling disc 200.

[0038] The specific shuffling disk 200 includes an annular sliding surface 210 and an annular plane 220 arranged around the center of the shuffling disk 200. The annular sliding surface 210 is mainly used to guide the mahjong tiles 300 falling on the shuffling disk 200 to move towards the annular plane 220 on the outer periphery. The annular sliding surface 210 can be an inclined arc surface or multiple inclined planes surrounding the center of the shuffling disk 200. The height of the annular sliding surface 210 near the center of the shuffling disk 200 is greater than the height of the annular sliding surface 210 away from the center of the shuffling disk 200. That is, the height of the annular sliding surface 210 decreases from the center to the outer periphery. During the rotation of the shuffling disk 200, the mahjong tiles 300 can slide naturally along the annular sliding surface 210 with the help of gravity, so that the mahjong tiles 300 move orderly from the center of the shuffling disk 200 to the edge, which improves the fluidity of the mahjong tiles 300 on the disk surface and helps to improve the efficiency and smoothness of shuffling.

[0039] The bottom edge of the circular plane 220 is connected to the circular sliding surface 210 to avoid gaps between the circular sliding surface 210 and the circular plane 220 that could cause the tiles to get stuck. Ideally, the circular plane 220 and the circular sliding surface 210 should have a smooth transition so that the mahjong tiles 300 can smoothly enter the circular plane 220 from the circular sliding surface 210. The circular plane 220 provides a relatively stable support surface for the mahjong tiles 300, preventing collisions or jamming caused by the tiles falling directly. It plays a role in buffering and transitioning, ensuring the smoothness of the shuffling process and reducing equipment failures and noise that may be caused by the disorderly movement of the mahjong tiles 300.

[0040] Furthermore, a flipping magnet 120 is provided on the shuffling chamber 100, and at least one flipping magnet 120 is provided on the bottom surface of the shuffling chamber 100 below each shuffling plate 200. The flipping magnet 120 is located below the annular plane 220 of the shuffling plate 200. The flipping magnet 120 is as close as possible to the annular plane 220 to maximize the magnetic attraction of mahjong tiles 300 that have not been flipped correctly. However, the flipping magnet 120 does not come into contact with the shuffling plate 200 to avoid obstructing the normal rotation of the shuffling plate 200. The magnetic poles of the flipping magnet 120 near the shuffling plate 200 control whether the mahjong tile 300 with its built-in magnet is face up or face down. In other words, if the magnetic poles of the magnet inside the mahjong tile 300 are opposite to those of the flipping magnet 120, the mahjong tile 300 will be attracted by the flipping magnet 120, causing it to move relative to the shuffling plate 200 until it flips due to collision with other mahjong tiles 300 or the action of the shuffling plate 200, achieving the goal of all mahjong tiles 300 facing the same direction. When the mahjong tile 300 is attracted and flipped, it is supported by the annular plane 220. Compared to placing the flipping magnet 120 in other positions, which might cause the mahjong tile 300 to be in an unstable state during the flipping process, this arrangement provides a more stable flipping fulcrum and movement plane for the mahjong tile 300, making the flipping action smoother and more stable. This reduces the risk of the mahjong tile 300 affecting the shuffling process due to shaking or displacement during the flipping process, thus helping to improve flipping efficiency.

[0041] To improve the flipping efficiency of the mahjong tiles 300, a flipping paddle 230 is provided on the circular plane 220. The flipping paddle 230 rotates with the shuffling plate 200 and comes into contact with the mahjong tiles 300 attracted by the flipping magnet 120, pushing the mahjong tiles 300 to flip with the flipping paddle 230 as the fulcrum. The shape of the flipping paddle 230 is not limited; it can be a semi-circular arc, a rectangle, or a polygon. The height of the flipping paddle 230 is approximately 1 / 5 to 1 / 4 of the height of the mahjong tiles 300, which is more conducive to flipping the mahjong tiles 300 when the flipping paddle 230 abuts and pushes them. The flipper 230 provides a clear fulcrum and driving direction for the flipping of the mahjong tiles 300, making the flipping process more stable and controllable. This ensures that the mahjong tiles 300 can be flipped accurately in the expected manner, improving the success rate and consistency of the flipping operation. Consequently, it enhances the shuffling quality and reliability of the automatic mahjong machine. This collaborative design fully utilizes the rotational power and magnetic field of the shuffling disc 200, achieving a highly efficient and stable flipping function without adding too many complex structures. Compared to some independently set and structurally complex flipping devices, it not only simplifies the overall structure of the equipment, reduces manufacturing costs and maintenance difficulty, but also improves the space utilization and operational stability of the equipment, resulting in optimized performance of the automatic mahjong machine and a better user experience.

[0042] Based on the above embodiments, the following solution can be adopted for driving the shuffling disk 200 to rotate:

[0043] 1. Each shuffling disc 200 is connected to an independent drive motor, meaning each shuffling disc 200 is driven to rotate independently, achieving precise control over each shuffling disc 200. The speed, direction, and other parameters of each shuffling disc 200 can be flexibly adjusted according to different shuffling needs, providing better adaptability when facing complex shuffling tasks or special combinations of mahjong tiles 300. The drive connection between the drive motor and the shuffling disc 200 can be achieved by the drive shaft of the drive motor directly driving the central shaft of the shuffling disc 200 to rotate, or by setting gear teeth 240 on the outer circumference of the shuffling disc 200, with the drive motor driving the shuffling disc 200 to rotate via gear transmission or chain transmission.

[0044] 2. Two or more shuffling disks 200 can share a single drive motor to achieve synchronous rotation. For example, in this embodiment, there are four shuffling disks 200, which can be grouped into pairs and driven by a single drive motor. Specifically, gear teeth 240 can be provided on the outer circumference of the shuffling disk 200, and the drive motor can drive the shuffling disk 200 to rotate via gear transmission or chain transmission. Figure 2 In this configuration, a transmission gear 500 is installed between two adjacent shuffling discs 200, which meshes with the outer teeth 240 of the two shuffling discs 200 simultaneously. The drive motor drives the transmission gear 500 to rotate, thereby simultaneously driving the two shuffling discs 200 to rotate.

[0045] Based on the above embodiments, such as Figure 4 , Figure 5As shown, the shuffling disc 200 needs to withstand the impact of the falling mahjong tiles 300 and ensure its smooth rotation. Therefore, multiple sets of roller assemblies 130 supporting the rotation of the shuffling disc 200 are provided at the bottom of the shuffling chamber 100. In this embodiment, a total of eight sets of roller assemblies 130 are provided below each shuffling disc 200, and all roller assemblies 130 are evenly distributed in the same ring. The roller assembly 130 can adopt existing publicly available technical solutions. For example, in this embodiment, the roller assembly 130 includes a wheel seat and a roller rotatably mounted on the wheel seat. The wheel seat is fixed to the bottom of the shuffling chamber 100, and the roller is rotatably mounted on the wheel seat via a rotating shaft. The roller contacts the bottom of the shuffling chamber 100, supporting the shuffling chamber 100 and ensuring its smooth rotation. Compared with other support methods, the rolling friction coefficient between the roller and the shuffling disc 200 is relatively small. This significantly reduces the resistance experienced by the shuffling disc 200 during rotation, allowing for smoother operation. It also reduces energy loss and component wear caused by excessive friction, improving equipment efficiency and extending the service life of the roller assembly 130 and the shuffling disc 200, ensuring stable performance of the automatic mahjong machine over long-term use. Multiple roller assemblies 130 evenly distribute the weight of the shuffling disc 200, maintaining good balance during rotation. Compared to structures with single-point support or fewer support points, this design effectively avoids tilting and wobbling of the shuffling disc 200 due to uneven force distribution, ensuring stable movement of the mahjong tiles 300 on the shuffling disc 200. It 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.

[0046] Furthermore, the shuffling disc 200 is provided with an annular track 250 protruding towards the bottom of the shuffling chamber 100. The roller assembly 130 rolls along the annular track 250. The annular track 250 allows the supporting force of the roller assembly 130 on the shuffling disc 200 to be evenly distributed along the track, effectively dispersing the force on the shuffling disc 200 during rotation. Compared with single-point or localized force, this uniform force distribution significantly reduces localized stress concentration, reduces the risk of deformation, wear, and other damage to the shuffling disc 200 caused by long-term uneven force distribution, thereby extending the service life of the shuffling disc 200, reducing equipment maintenance costs and replacement frequency, 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 disc surface and improving the overall strength of the shuffling disc 200.

[0047] In addition, the shuffling disc 200 in this embodiment also has several weight-reducing holes 260. These holes 260 can be provided only on the annular sliding surface 210 or the circular plane 220, or they can cover both the annular sliding surface 210 and the circular plane 220. The size, shape, and distribution of the weight-reducing holes 260 can be selected according to the size and strength of the shuffling disc 200. Providing weight-reducing holes 260 reduces the weight of the shuffling disc 200. During automatic mahjong machine operation, a lighter shuffling disc 200 means less energy required for motor drive, thus achieving energy saving and reducing equipment operating costs. Simultaneously, the reduced weight also contributes to the stability and dynamic performance of the overall equipment structure, reducing unnecessary inertial loads and improving the equipment's response speed and operating efficiency. Furthermore, the weight-reducing holes 260 play an important role in reducing noise. During the shuffling process, the collision between the mahjong tiles 300 and the shuffling disc 200, as well as the rotational vibration of the shuffling disc 200, are the main sources of noise. The presence of the weight-reducing hole 260 alters the vibration mode and energy transfer path of the shuffling disc 200, effectively absorbing and dispersing the energy generated by collisions and vibrations, thus reducing noise generation and propagation. Compared to a design without the weight-reducing hole 260, this significantly reduces the noise level of the automatic mahjong machine during operation, creating a relatively quiet and comfortable gaming environment for players, improving user experience and satisfaction, and enhancing the product's competitiveness in the market.

[0048] Multiple reinforcing ribs 270 are radially distributed from the center of the shuffling disc 200, providing a strong support structure. While reducing weight, this significantly enhances the rigidity and deformation resistance of the shuffling disc 200, enabling it to better withstand the frequent impacts and friction of the mahjong tiles 300 during the shuffling process. This structural design ensures that the shuffling disc 200 maintains good geometry and mechanical properties during long-term use, improving the reliability and durability of the equipment, reducing downtime for maintenance due to component damage, and thus guaranteeing the continuous and stable operation of the automatic mahjong machine.

[0049] Furthermore, to enhance the overall strength of the shuffling disc 200, reinforcing ribs 270 extend from the center of the shuffling disc 200 to its outer periphery. Multiple reinforcing ribs 270 are incorporated based on the size, material, and thickness of the shuffling disc 200. This ensures that the shuffling disc 200 will not deform when impacted by falling mahjong tiles 300, nor will it deform when subjected to a large number of mahjong tiles 300 piled on it, ensuring long-term stable operation. To simplify the structure of the shuffling disc 200, in this embodiment, the reinforcing ribs 270 are designed to protrude from the upper surface of the shuffling disc 200. The reinforcing ribs 270 located on the annular plane 220 form flipping paddles. When they encounter mahjong tiles 300 attracted by the flipping magnet 120, they flip the mahjong tiles, thus reducing the number of components on the shuffling disc. Moreover, the reinforcing ribs 270 and the shuffling disc 200 can be integrally formed, ensuring the strength of the reinforcing ribs 270.

[0050] By changing the previous method of setting one shuffling plate 200 in the shuffling chamber 100 to setting at least two shuffling plates 200, not only can the area of ​​the shuffling chamber 100 be expanded, allowing for a larger shuffling area and full utilization of the space under the main unit, but also the shuffling efficiency is improved due to the increased shuffling area. The number of mahjong tiles 300 per unit area is reduced, the probability of mahjong tiles 300 colliding is reduced, and the shuffling noise is also reduced. The reduced number of mahjong tiles 300 per unit area also reduces the probability of mahjong tiles 300 stacking. Each shuffling plate 200 processes a relatively smaller number of tiles, and the mahjong tiles 300 have more space in their respective shuffling plates 200 to tumble and mix, reducing the chance of tiles getting stuck due to excessive stacking and making the shuffling process smoother.

[0051] Example 2:

[0052] like Figure 1 , Figure 6 , Figure 7 As shown in Embodiment 1, to address the issue of guiding mahjong tiles pushed into the shuffling chamber from the entry port onto the shuffling trays, specifically, since at least two shuffling trays 200 are used, gaps will exist between adjacent shuffling trays 200. If mahjong tiles 300 fall into these gaps, they cannot be processed by the shuffling trays 200. To fill these gaps and guide the mahjong tiles 300 that would otherwise fall into these gaps onto the shuffling trays 200, a guide component 400 is provided inside the shuffling chamber 100, and the guide component 400 is positioned below the entry port to better utilize its function. The guide component 400 has a guide surface 410 corresponding to each shuffling tray 200; that is, the number of guide surfaces 410 on the guide component 400 corresponds to the number of shuffling trays 200, guiding the mahjong tiles 300 falling from the entry port to the corresponding shuffling tray 200.

[0053] The mahjong tiles 300 not only need to rotate with the shuffling plate 200, but also need to take advantage of the fact that when the mahjong tiles 300 hit the side wall around the shuffling plate 200, the mahjong tiles 300 will generate relative movement with the shuffling plate 200 due to friction with the side wall. This relative movement can also cause the mahjong tiles 300 to be scattered and flipped over by the flipping magnet 120 in the shuffling chamber 100. In order to form a sidewall around the shuffling plate 200, a blocking part 110 is provided in the shuffling chamber 100. The blocking part 110 is located on the outer periphery of the shuffling plate 200 away from the card entry port, and the card guide surface 410 is located on the outer periphery of the shuffling plate 200 near the card entry port. The blocking part 110 and the card guide surface 410 together form the sidewall of the shuffling plate 200 or form part of the sidewall. When the mahjong tiles 300 are subjected to various forces such as centrifugal force of the shuffling plate 200 and their own gravity, the blocking part 110 and the card guide surface 410 can prevent the mahjong tiles 300 from sliding off the shuffling plate 200 or moving to other areas due to the force, ensuring that the mahjong tiles 300 are always shuffled within the designated shuffling plate 200 area.

[0054] The blocking part 110 and the card guide 400 can form a completely closed ring, separating each shuffling tray 200 into an independent area. Alternatively, the blocking part 110 and the card guide 400 can form an open ring, allowing the shuffling trays 200 to communicate with each other, so that mahjong tiles 300 can move from one shuffling tray 200 to another adjacent shuffling tray 200. Specifically:

[0055] The blocking part 110 and the guide 400 form a closed ring, independently separating the shuffling trays 200, ensuring that each shuffling tray 200 operates in a relatively independent and stable spatial environment. During the shuffling process, the rotation of each shuffling tray 200 and the movement of the mahjong tiles 300 do not interfere with each other, avoiding problems such as tile confusion and increased collisions that may occur due to mutual influence between adjacent shuffling trays 200. This ensures that each shuffling tray 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. Because it is a closed ring, the mahjong tiles 300 entering the shuffling tray 200 will also have more opportunities to be scattered and flipped.

[0056] The guide plate surface 410 can be extended to and connected to the blocking part 110, or a separator 430 can be provided to connect the blocking part 110 and the guide plate surface 410. Since the separator 430 only serves a blocking function, it can be detachable for easy replacement after damage or deformation. When the separator 430 adopts a split structure, it can be inserted into the blocking part 110 through a slot, or a rib can be provided on the guide plate 400 to cooperate with the slot, or other detachable connection methods can be used to connect the separator 430 to the blocking part 110 and the guide plate body. Alternatively, the separator 430 can be integrally set with the guide plate body for easy manufacturing and installation. The guide plate 400 is provided with the separator 430 connecting the corresponding blocking part 110 and the guide plate surface 410, so that the guide plate 400, the blocking part 110 and the guide plate surface 410 form an organic whole structure, which better separates the shuffling plate 200 independently. 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 the various stresses generated by the machine operation, reducing the relative displacement and loosening risk between components, thereby improving the stability and reliability of the entire structure and ensuring the continued effectiveness of the guiding and blocking functions during long-term use.

[0057] Furthermore, the bottom edge of the guide surface 410 and the bottom surface of the separator 430 are both lower than the contact surface between the shuffling tray 200 and the mahjong tiles 300. Under the action of gravity, the mahjong tiles 300 can more easily slide smoothly along the guide surface 410 to the corresponding shuffling tray 200, avoiding the mahjong tiles 300 getting stuck between the bottom edge of the guide surface 410 and the shuffling tray 200, or the mahjong tiles 300 getting stuck. This reduces the possibility of the mahjong tiles 300 getting stuck or piling up due to the bottom surface being too high, making the guiding process of the mahjong tiles 300 smoother and helping to improve the shuffling efficiency of the entire automatic mahjong machine.

[0058] The shuffling discs 200 are interconnected, and there are at least three shuffling discs 200. The blocking part 110 and the guide surface 410 form a ring with a gap, which connects the adjacent shuffling discs 200. This interconnected structure allows the mahjong tiles 300 to be appropriately adjusted and redistributed among the different shuffling discs 200 according to the actual situation. If there are too many mahjong tiles 300 in a shuffling disc 200, they can overflow from the gap to the adjacent shuffling discs 200, speeding up the shuffling speed and avoiding situations where there are too many or too few mahjong tiles 300 on some shuffling discs 200. This further optimizes the distribution balance of mahjong tiles 300 on multiple shuffling discs 200 and improves the shuffling efficiency.

[0059] Based on the above embodiment, a separating ridge 420 is provided between adjacent guide surfaces 410 on the guide component 400. After the mahjong tile 300 encounters the separating ridge 420, it can quickly tilt towards one side of the guide surface 410 of the separating ridge 420, thereby accelerating the guiding speed of the mahjong tile 300 and preventing the mahjong tile 300 from getting stuck between the two guide surfaces 410. The separating ridge 420 can also extend in the direction of the blocking part 110 to form a separating member 430.

[0060] For the guide surface 410, its height gradually decreases and its width gradually increases from the center of the shuffling chamber 100 to the edge of the corresponding shuffling tray 200. This design conforms to the movement law of the mahjong tiles 300 under the action of gravity. The gradual decrease in height provides a natural slope for the mahjong tiles 300 to slide smoothly from near the entry point to the shuffling tray 200; the gradual increase in width provides more space for the mahjong tiles 300, avoiding congestion or obstructed sliding during the guiding process. This effectively improves the guiding efficiency of the mahjong tiles 300 from the entry point to the shuffling tray 200, reduces the time the mahjong tiles 300 spend on the guide surface 410, and speeds up the shuffling process. This design allows the mahjong tiles 300 to be more evenly distributed across the shuffling trays 200. Because of the special shape of the guide surface 410, the mahjong tiles 300 can be guided to slide down in an orderly manner, avoiding concentrated accumulation or uneven distribution of the mahjong tiles 300 in a certain area. This ensures that each shuffling plate 200 is in a relatively balanced state when initially receiving the mahjong tiles 300. This is beneficial for each shuffling plate 200 to operate on approximately the same number and distribution of mahjong tiles 300 during subsequent shuffling processes, thereby improving the shuffling uniformity of the entire automatic mahjong machine, enhancing the shuffling effect and quality, and providing players with a fairer playing environment.

[0061] Furthermore, the bottom edge of the guide surface 410 is rounded and matches the curvature of the outer ring of the shuffling plate 200. This rounded design effectively reduces the gaps between the guide surface 410 and the shuffling plate 200. During the guiding of the mahjong tiles 300, this significantly reduces the risk of the tiles getting stuck in these gaps, ensuring that the tiles can smoothly slide from the guide surface 410 onto the shuffling plate 200. This maintains the smoothness of the shuffling process, avoids equipment malfunctions and shuffling interruptions due to tile jamming, and improves the operational stability and reliability of the automatic mahjong machine.

[0062] Based on the above embodiment, the shuffling discs 200 are evenly distributed on a circular trajectory centered on the center of the shuffling chamber 100. The guide component 400 is located at the center of the shuffling chamber 100, and the inlet is located directly above the guide component 400. This layout allows the mahjong tiles 300 to be evenly distributed and guided to the surrounding shuffling discs 200 after falling from the inlet. Compared to a cluttered layout, this design makes full use of the space in the shuffling chamber 100, reduces mutual interference and collisions of the mahjong tiles 300 during the guidance process, improves the efficiency and uniformity of the tile flow guidance, and helps to improve the overall shuffling effect.

[0063] Example 3

[0064] This embodiment can be implemented based on Embodiment 1 or 2, or it can be implemented on other types of automatic mahjong machines.

[0065] like Figure 2 , Figure 8 The following is a third embodiment of the automatic mahjong machine of this utility model. The main body of the automatic mahjong machine in this embodiment is also provided with a circular main track 600 and at least one set of card feeding components 700 for picking up mahjong tiles 300 from the shuffling plate 200. Each set of card feeding components 700 is connected to the main track 600 through a secondary track 800, and the mahjong tiles 300 picked up by the card feeding components 700 are transported from the secondary 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. The conveying mechanism 610 drives the mahjong tiles 300 to move in the same direction within the main track 600. Once a set of stacking mechanisms is full of mahjong tiles 300, any excess mahjong tiles 300 will be carried to the next stacking mechanism instead of being returned to the shuffling tray 200. Therefore, as long as the mahjong tiles 300 shuffled by the shuffling tray 200 are picked up by the delivery component 700, the shuffling tray 200 completes the shuffling work, shortening the shuffling time and avoiding prolonged operation. Furthermore, the circular main track 600 not only transports the mahjong tiles 300 to each stacking mechanism but also serves as a storage component for the mahjong tiles 300. When the speed at which the mahjong tiles 300 are fed into the main track 600 exceeds the stacking speed of the stacking mechanism, the main track 600 can also serve as a storage component, ensuring that both the delivery component 700 and the shuffling tray 200 can operate continuously, completing the shuffling work as quickly as possible and reducing the time for shuffling noise to occur. Specifically, the main track 600 can be set as a circle or a rounded quadrilateral to avoid forming right angles or corners with too small an angle, thus preventing the mahjong tiles 300 from getting stuck in the main track 600. In this embodiment, the main track 600 is located above the shuffling chamber 100, thereby avoiding the main track 600 from affecting the arrangement of the shuffling chamber 100. Moreover, the main track 600 can be set along the edge of the shuffling chamber 100, which can maximize the perimeter of the main track 600 and allow it to hold more mahjong tiles 300.

[0066] Furthermore, the widths of the main track 600 and the secondary track 800 are adapted to the width of a single mahjong tile 300. That is, the widths of the main track 600 and the secondary track 800 are the same as the width of a single mahjong tile 300, or slightly larger, to ensure that the mahjong tiles 300 do not get stuck within the main track 600 and the secondary track 800, allowing them to move smoothly along these tracks. The mahjong tiles 300 will move in a single line within the main track 600, avoiding a disorderly horizontal or vertical arrangement within the main track 600 and the secondary track 800. This allows the tile-grabbing component to systematically pick up the mahjong tiles 300 within the main track 600.

[0067] In addition, to facilitate the smooth entry of the mahjong tiles 300 on the secondary track 800 into the main track 600, the angle between the conveying direction of the mahjong tiles 300 on the secondary track 800 and the conveying direction of the mahjong tiles 300 on the main track 600 is an acute angle. That is, the mahjong tiles 300 on the secondary track 800 have a component velocity that moves in the same direction as the mahjong tiles 300 on the main track 600. After the mahjong tiles 300 on the secondary track 800 are partially inside the main track 600, they can also be pushed completely into the main track 600 by the conveying mechanism 610 inside the main track 600.

[0068] A single-tile passing component 900 is installed at the intersection of the main track 600 and the secondary track 800. The single-tile passing component 900 controls the passage of mahjong tiles 300 at the intersection of the main track 600 and the secondary track 800, ensuring that only mahjong tiles 300 from the main track 600 or the secondary track 800 can pass through the intersection of the two tracks at the same time. This prevents mahjong tiles 300 from being stuck in the tracks if they are located at the intersection of the main track 600 and the secondary track 800 at the same time.

[0069] Single-card components 900 include, but are not limited to, the following structural forms:

[0070] The first type is a purely mechanical form. The single-tile passing component 900 includes a control element 910 that is oscillating at the intersection of the main track 600 and the secondary track 800. When a mahjong tile 300 passes through the control element 910 on the main track 600, it pushes the control element 910 to swing towards the secondary track 800. That is, at least part of the control element 910 is located within the secondary track 800. Since the width of the secondary track 800 is equal to the width of the mahjong tile 300, the fact that part of the control element 910 is located within the secondary track 800 will block the mahjong tile 300 within the secondary track 800 from continuing to move. The mahjong tile 300 within the secondary track 800 can only push the control element 910 aside and enter the main track 600 after the mahjong tile 300 on the main track 600 has passed through. Similarly, if the mahjong tile 300 in the secondary track 800 reaches the junction of the main track 600 and the secondary track 800 first, the mahjong tile 300 in the secondary track 800 will push the control component 910 to swing towards the main track 600. The control component 910 will be at least partially located in the main track 600. Similarly, the width of the main track 600 is equal to the width of the mahjong tile 300. The partial intrusion of the control component 910 into the main track 600 will prevent the mahjong tile 300 in the main track 600 from continuing to move. Only after the mahjong tile 300 in the secondary track 800 enters the main track 600 can the mahjong tile 300 in the main track 600 push away the control component 910 to continue moving.

[0071] In this embodiment, the control component 910 includes a transition portion 911 and a first blocking surface 912 and a second blocking surface 913 located on both sides of the transition portion 911. The entire transition portion 911 can be made into a triangular prism shape, with one corner forming the transition portion 911. It is connected to the junction of the main track 600 and the secondary track 800 via a rotating shaft. The rotating component is located near the upstream side of the junction of the main track 600 and the secondary track 800 to promptly block the mahjong tile 300 in the other track. The first blocking surface 912 blocks the mahjong tile 300 from passing through the secondary track 800 on the main track 600. Within the main track 600, the second blocking surface 913 blocks the mahjong tile 300 within the secondary track 800. Since the entire transition part 911 is a triangular prism shape, and both the first blocking surface 912 and the second blocking surface 913 are sides of the transition part 911, after the mahjong tile 300 passes through the main track 600, the mahjong tile 300 on the secondary track 800 can smoothly slide along the second blocking surface 913, successfully pushing the control component 910 away and preventing it from jamming with the mahjong tile 300 on the secondary track 800. Similarly, the first blocking surface 912 has a similar effect. Because the swing-set control component 910 controls the opening and closing of the main track 600 and the secondary track 800 through a purely mechanical means, and because the control component 910 has a simple structure and high reliability, it can meet the high-speed, frequent passage of the mahjong tile 300.

[0072] The second method employs electronic control. The single-tile passage component 900 includes a sensor and a sensor-controlled blocking element. At the intersection of the main track 600 and the secondary track 800, both the main track 600 and the secondary track 800 are equipped with sensors and blocking elements. The blocking element can be linear, meaning that when triggered, it extends into the corresponding track; otherwise, it remains outside the track and does not affect the movement of the mahjong tile 300 within the track. Alternatively, the blocking element can be oscillating, meaning that when triggered, it rotates along its axis into the corresponding track, and after the mahjong tile 300 in the other track passes, it swings out of the current track, allowing the mahjong tile 300 to pass. The sensor can be a Hall effect sensor, which detects the magnetic field of the mahjong tile 300 to determine whether it needs to pass through the intersection of the two tracks; or it can be an infrared sensor, triggered when the mahjong tile 300 passes. Electronic sensors have high sensitivity, allowing for convenient control of the opening and closing of the main track 600 and the secondary track 800, and can also be linked with sensors such as counters to control the blocking element's movement while counting.

[0073] When there is only one shuffling plate 200 in the shuffling chamber 100, the more sets of card feeding components 700 there are, the faster the mahjong tiles 300 can be picked up from the shuffling plate 200 and put into the main track 600. Of course, the shuffling efficiency of the shuffling plate 200 also needs to be considered, and the number of card feeding components 700 should be reasonably controlled. All card feeding components 700 can be evenly distributed in the main unit to avoid a large accumulation of mahjong tiles 300 in a certain section of the main track 600. When there are multiple shuffling plates 200 in the shuffling chamber 100, the number of card feeding components 700 is equal to the number of shuffling plates 200. For example, in embodiment one, four shuffling plates 200 are arranged, and each shuffling plate 200 corresponds to a set of card feeding components 700. This can ensure that the shuffled mahjong tiles 300 on each shuffling plate 200 can be picked up and put into the main track 600. Even if there are too many mahjong tiles 300 on a certain shuffling plate 200, it can be ensured that all card stacking components can pick up a sufficient number of mahjong tiles 300 to complete the card stacking work. In this embodiment, the card feeding component 700 and the card grading component can both refer to the structure in the prior art. The card feeding component 700 includes a roller with a magnet, a motor that drives the roller to rotate, and a bracket that supports the roller to rotate. The roller attracts the mahjong tiles 300 that have been shuffled on the shuffling plate 200 through the magnet and carries them to the secondary track 800 to be transported to the main track 600.

[0074] Based on the above embodiments, the conveying mechanism 610 includes, but is not limited to, the following structures:

[0075] The first method involves having at least two sets of card-feeding components 700, for example, four sets of card-feeding components 700, which are designated as the first, second, third, and fourth sets in a clockwise direction. The number of conveying mechanisms 610 is equal to the number of card-feeding components 700, meaning there are four sets of conveying mechanisms 610, each with the same number as the card-feeding components 700. The conveying mechanism 610 extends from the card-in port of the secondary track 800 along the conveying direction of the mahjong tiles 300 on the main track 600 to the card-out port of the adjacent secondary track 800. In other words, the conveying mechanism 610 carries the mahjong tiles 300 from the card-in port of the first secondary track 800 into the main track 600 and continues to convey them to the card-out port of the second secondary track 800 on the main track 600. This arrangement of four conveying mechanisms 610 will cover the entire main track 600 and secondary track 800, ensuring that the mahjong tiles 300 in the secondary track 800 can smoothly enter the main track 600. The conveying mechanism 610 can use a first conveyor belt or conveyor rollers to ensure that the mahjong tiles 300 can move smoothly. In this embodiment, the conveying mechanism 610 uses a first conveyor belt. Figure 1 , Figure 2 and Figure 4 The conveyor belt is not shown; only the conveyor wheel that drives the conveyor belt is indicated.

[0076] The second configuration involves the conveyor mechanism 610 being positioned along the main track 600. In this configuration, the conveyor mechanism 610 is solely responsible for moving the mahjong tiles 300 on the main track 600. A push wheel 810 is installed on each secondary guide rail, pushing the mahjong tiles 300 onto the main track. The structure and number of conveyor mechanisms 610 in this configuration are not affected by the number of secondary tracks 800. Adding secondary tracks 800 simply requires installing push wheels 810 on the corresponding tracks, offering greater flexibility in arrangement. The conveyor mechanism 610 can also utilize a second conveyor belt or conveyor rollers.

[0077] Through the structure of the automatic mahjong machine described above, the shuffling disc 200 only needs to shuffle the mahjong tiles 300 once, and will not accept mahjong tiles 300 returned from the tile stacking component. This shortens the running time of the shuffling disc 200, thereby reducing the time of noise generated during shuffling and improving the user experience. Furthermore, this embodiment uses a circular main track 600, within which the mahjong tiles 300 move continuously until they are picked up by the tile stacking component. This not only transports the mahjong tiles 300 to each tile stacking mechanism, but also serves as a storage component for the mahjong tiles 300. This allows the shuffling disc 200, the tile delivery component 700, and the tile stacking component to operate independently at their respective optimal speeds, completing their tasks as quickly as possible.

[0078] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
