Description

Technical Field

[0001] The utility model relates to the technical field of mahjong machines, in particular to a universal mahjong machine shuffling tray system. Background Art

[0002] Mahjong machines are used to automatically sort, stack, and advance tiles, and are commonly used in mahjong games. They save time, reduce manual sorting, stacking, and placement, and ensure fairness during the game.

[0003] The size of mahjong tiles in various parts of the Chinese market has been increasing year by year, and the weight of the tiles has also increased, which has put higher requirements on the operation of the shuffling plate system. Existing mahjong machines generally use single-sided motors, which have high torque requirements for the motors and shorten the motor life. The increase in the size of mahjong tiles will affect the stability of the shuffling plate and make more noise during use.

[0004] Therefore, a universal mahjong machine shuffling system is provided to solve the above problems. Utility Model Content

[0005] The utility model proposes a universal mahjong machine shuffling plate system, which aims to solve the problems in the prior art of high torque requirements for the motor, resulting in a short motor life, increased mahjong affecting the stability of the shuffling plate, and high noise during use.

[0006] In order to achieve the above-mentioned object, the utility model adopts the following technical scheme: a universal mahjong machine shuffling plate system, comprising a shuffling plate, a central shaft seat and a driving device; the shuffling plate comprises a shuffling plate window cover, a shuffling plate tooth plate, a cover-scraping strip and a card-digging tendon block, and the driving device comprises a driving motor and a driving gear; the shuffling plate window cover is located on the upper surface of the shuffling plate, the shuffling plate tooth plate is located on the lower surface of the shuffling plate, the cover-scraping strip is installed above the shuffling plate, the card-digging tendon block is located around the upper surface of the shuffling plate, the central shaft seat is located at the center of the shuffling plate, the driving motor is installed on the lower surface of the shuffling plate, and the driving gear is installed at the output end of the driving motor;

[0007] Two driving motors are provided on the lower surface of the shuffling disk, and the driving gears provided on the two driving motors are both engaged with the toothed disk of the shuffling disk.

[0008] Preferably, the shuffling plate is divided into eight equal parts and provided with reinforcing ribs, and the tail end of the outer ring of the reinforcing ribs is provided with a rectangular hollow groove for installing the card-digging tendon block, and the outer ring of the shuffling plate is provided with a surrounding edge.

[0009] Preferably, the shuffling tray window cover is provided with a socket, a shuffling tray screw hole, and a cover lifting hole.

[0010] Preferably, the middle of the scratching strip with cover is a hollow cone, and the root of the cone is evenly divided outward into four arc-shaped scratching strips. There are protruding vertical ribs on the inner side of the flip side of the hollow cone of the scratching strip with cover.

[0011] Preferably, the central shaft seat is sequentially divided into the first step, the second step, the third step and the fourth step from top to bottom.

[0012] Preferably, a shuffling plate is mounted on the third step of the central shaft seat and the shuffling plate is supported by the fourth step of the central shaft seat.

[0013] Preferably, a vertical groove is provided on the second step of the central shaft seat, the vertical groove corresponds to the vertical rib on the scratch-off strip, and the top of the vertebral body of the scratch-off strip corresponds to the first step of the central shaft seat.

[0014] The present invention comprises a shuffling tray, a central shaft seat, and a drive mechanism. The shuffling tray includes a shuffling tray window cover, a shuffling tray toothed disc, a cover and card scraping strip, and a card shifting block. The drive mechanism includes a drive motor and a drive gear. The shuffling tray window cover is located on the upper surface of the shuffling tray, the shuffling tray toothed disc is located on the lower surface of the shuffling tray, the cover and card scraping strip is mounted above the shuffling tray, and the card shifting block is located around the upper surface of the shuffling tray. The central shaft seat is located at the center of the shuffling tray, the drive motor is mounted on the lower surface of the shuffling tray, and the drive gear is mounted on the output end of the drive motor. The central shaft seat and drive motor of the present invention are both mounted and fixed on the iron base of the mahjong machine. The drive gear and drive motor are connected via a flat square shaft provided by the motor and secured with locking screws. The drive motor and drive gear are divided into two groups, equidistantly spaced outward from the concentric position of the central shaft seat. The inner circle of the tray is largely conical, with the central inner circle inserted into the third step of the central shaft seat and supported by the fourth step of the central shaft seat. The outer circle of the shuffle tray is a flat, concentric circle connected to the inner circle. The inner circle of the outer plane houses 10 tracks supporting the roller assembly. Supports at both the center and the outside ensure smooth rotation and withstand the weight of the mahjong tiles (144 tiles weigh from 10 to 40 kilograms, depending on the tile pattern). The shuffle tray is divided into eight equal sectors with reinforcing ribs. One of the eight sectors features a removable shuffle tray window. This window allows for easy installation, inspection, and maintenance of the drive motor and lifting mechanism underneath the shuffle tray. The shuffle tray also optimizes the positioning of the motor and shuffle tray sprockets. Unlike conventional mahjong machine shuffle trays, which use a single drive motor with the motor-driven gear driving the shuffle tray inward, the optimized design features dual equally spaced motors, with the motor-driven gears driving the shuffle tray outward. The first feature of the optimized system is that because the motor drive gear drives the shuffle plate sprockets outward, the significantly increased diameter of the shuffle plate sprockets significantly reduces the torque requirement for the drive motor, significantly extending the motor's life. The second feature of the optimized system is that the dual-sided motor drive makes the shuffle plate stable and balanced, greatly reducing and balancing the reaction torque on the central shaft seat, shuffle plate roller assembly, and drive motor. This provides greater stability and a longer service life for the entire shuffle plate system. The third feature of the optimized system is that the dual-sided motor drive power and torque are significantly superior to those of an oversized single-drive shuffle plate motor, and operating noise is significantly reduced. The dual-drive motor uses a conventional size and power drive motor to meet the operating requirements of all card sizes, eliminating the need for more expensive custom oversized drive motors.

[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] It should be understood that the terms "upper", "lower", "left", "right", "front", "back", "middle", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0029] Reference Figure 1-11, an embodiment of the present invention provides a universal mahjong machine shuffling plate system, including a shuffling plate 1, a central shaft seat 3 and a driving device; the shuffling plate 1 includes a shuffling plate window cover 2, a shuffling plate tooth plate 7, a cover-scraping strip 4 and a card-digging tendon block 5, and the driving device includes a driving motor 8 and a driving gear 6; the shuffling plate window cover 2 is located on the upper surface of the shuffling plate 1, the shuffling plate tooth plate 7 is located on the lower surface of the shuffling plate 1, the cover-scraping strip 4 is installed above the shuffling plate 1, the card-digging tendon block 5 is located around the upper surface of the shuffling plate 1, and the central shaft seat 3 is located at the bottom surface of the shuffling plate 1. The driving motor 8 is installed on the lower surface of the shuffling tray 1 at the center of the shuffling tray 1, and the driving gear 6 is installed at the output end of the driving motor 8. The shuffling tray 1 is divided into eight equal parts and provided with reinforcing ribs. The tail end of the outer ring of the reinforcing rib is provided with a rectangular hollow groove for installing the card-dipping tendon block 5. The outer ring of the shuffling tray 1 is provided with a surrounding edge 14. The shuffling tray window cover 2 is provided with a socket, a shuffling tray screw hole 12, and a cover-lifting hole 9. Two driving motors 8 are provided on the lower surface of the shuffling tray 1, and the driving gears 6 provided on the two driving motors 8 are engaged with the shuffling tray gear plate 7.

[0030] As can be understood, the central shaft seat 3 and the drive motor 8 are both installed and fixed on the iron bottom plate of the mahjong machine. The drive gear 6 and the drive motor 8 are connected by a flat square shaft provided by the motor and fixed with a locking screw. The drive motor 8 and the drive gear 6 are divided into two groups, which are evenly distributed outward from the concentric position of the central shaft seat 3. The shuffling plate 1 is divided into eight equal parts with reinforcing ribs, which are divided into eight sectors with equal areas. There is a rectangular hollow at the tail end of each reinforcing rib to the outer circle for the installation of the trapezoidal card-dividing tendon block 5. The card-dividing tendon block 5 can push the mahjong tiles against the outer circle of the large plate forward when the large plate rotates, and can also push down the mahjong tiles on one side of the mahjong machine when the excess tiles are shuffled and transported out and sucked on the card suction wheel to continue shuffling. The eight sectors and raised reinforcing ribs of the shuffling plate not only play the role of strengthening the strength of the large plate to prevent deformation, but also are used for the block pasting of the shuffling plate patch, which can also play a good role in reducing the noise of shuffling. The tapered surface of the shuffling tray 1 features magnet mounting slots 11 positioned at different locations in blind spots (in certain specific positions and states, tiles can spin and stagnate in blind spots due to the combined effects of the tray, scraper, and magnetic field, preventing shuffling) based on the size of the tiles. This effectively solves the problem of difficulty in shuffling the last tile. One of the eight sectors of the shuffling tray 1 features a removable shuffling tray window cover 2. The shuffling tray window cover 2 is equipped with a socket, shuffling tray screw holes 12, and a cover-lifting hole 9. The socket is inserted into two screw holes in the shuffling tray slots for alignment, and then secured with screws. The screws are loosened, and the cover 2 can be removed by grasping the cover-lifting hole 9 with your fingers. The proposed shuffling tray window cover 2 can facilitate the installation, inspection or maintenance of the drive motor 8, lifting mechanism, etc. under the shuffling tray 1, without the need to remove the conveying and lifting dice trays, scraper bars, shuffling tray 1, etc. to install, inspect or repair the bottom of the shuffling tray as in conventional mahjong machines. This opening cover design greatly facilitates the disassembly, inspection and maintenance of the bottom of the shuffling tray. The shuffling tray 1 is also provided with a position for adding φ4 / 5mm beef tendon bars, which are symmetrically arranged at the lower middle position of the conical surfaces on both sides of the shuffling tray. The φ4 / 5mm tendon strip can be folded in half and pressed into the tendon groove 13 on the back of the shuffle tray. The folded portion can be screwed into the screw hole with a washer to press and secure it. The two tendon heads can be installed on the left and right sides according to the different bending directions of the cover-scraping strip 4, achieving versatility between general mahjong machines and track-rotating mahjong machines. This shuffle tray 1 is similar to general mahjong machines and is also equipped with an upturned edge 14 to prevent mahjong tiles from being pushed out of the shuffle tray 1 at the edge of the shuffle tray. The shuffle tray 1 also optimizes the position of the motor and shuffle tray gear plate 7. The general mahjong machine shuffle tray 1 uses a single drive motor 8 for unilateral drive and a motor drive gear 6 to drive the shuffle tray gear plate 7 inward. After optimization, it is driven by two equally spaced motors, and the motor drive gear 6 drives the shuffle tray gear plate 7 outward. The optimized feature is that the motor drives the gear 6 outward to drive the shuffle plate gear 7, and the diameter of the shuffle plate gear 7 is significantly increased, which significantly reduces the torque requirement of the driving motor and greatly extends the life of the motor.The second optimized feature is that the dual-motor drive ensures a smooth and balanced shuffle tray. This significantly reduces and balances the reaction torque on the central shaft 3, the shuffle tray roller assembly, and the drive motor 8, resulting in greater stability and a longer service life for the entire shuffle tray system. The third optimized feature is that the dual-motor drive power and torque are significantly superior to an oversized single-drive shuffle tray motor, significantly reducing operating noise. The dual-drive motor utilizes a conventionally sized and powerful drive motor 8 to handle the full range of card sizes, eliminating the need for a more costly, custom-made, oversized drive motor 8.

[0031] In one embodiment, the middle of the scratch-off strip 4 is a hollow cone, and the root of the cone is evenly divided into four arc-shaped scratch-off strips. The inner side of the hollow cone of the scratch-off strip 4 is provided with protruding vertical ribs. The central shaft seat 3 is composed of the first step, the second step, the third step and the fourth step from top to bottom. The shuffling plate 1 is mounted on the third step of the central shaft seat 3 and the shuffling plate 1 is supported by the fourth step of the central shaft seat 3. A vertical groove is provided on the second step of the central shaft seat 3, and the vertical groove corresponds to the vertical rib on the scratch-off strip 4. The top of the cone of the scratch-off strip 4 corresponds to the first step of the central shaft seat 3.

[0032] As you can understand, the inner circle of the shuffling tray 1 is largely conical, with the center inner circle nestled within the third step of the central shaft seat 3 and supported by the fourth step of the central shaft seat 3. The outer circle of the shuffling tray 1 is a flat, concentric circle connected to the inner circle, with the inner circle of the outer circle serving as the track for the supporting roller assembly. Both the center and outer surfaces support the shuffling tray 1, ensuring smooth rotation and withstanding the heavy weight of the mahjong tiles (144 tiles weighing from 10 to nearly 40 kilograms, depending on the tile type). Similar to conventional mahjong machines, this structure also features a scratching bar. The difference is that the scraping bar, gland nut, and center gland of conventional mahjong machines are combined into a single component, improving assembly efficiency and simplifying maintenance and disassembly. The scratching bar 4, which is connected to the lid, is a hollow cone in the center. The base of the cone evenly divides the scraping bar into four arc-shaped strips. A counterclockwise curvature of the scraping bar tip is typical for conventional mahjong machines, while a clockwise curvature of the scraping bar tip is typical for mahjong machines. The inner side of the hollow cone of the scratching strip 4 with cover has protruding vertical ribs corresponding to the vertical grooves of the second stage of the center axis seat 3. The center circle of the top plane of the cone of the scratching strip 4 with cover corresponds to the first stage of the center axis seat 3. The gaps on both sides of the center circle are for the screw posts on both sides of the first stage of the center axis seat 3. There are two screw holes on the top plane of the scratching strip 4 with cover corresponding to the four screw holes on the upper plane of the second stage of the center axis seat 3. Different insertion positions can be used to achieve the position of the tip of the scratching strip for different sizes of cards corresponding to the large flip magnet under the shuffling plate 1 (large and small cards have different flip positions on the large flip magnet, and the tip of the scratching strip requires two optimal flip positions). The screw posts on both sides of the first stage of the center axis seat 3 are used to screw in screws to adjust the flushness of the dice plate and the table top of the mahjong machine.

[0033] The size of mahjong tiles in various parts of the Chinese market has been increasing year by year, and the weight of mahjong tiles has also increased, which has put higher requirements on the operation of the shuffling system. The overall optimization and innovation of the above-mentioned shuffling system has the advantages of better versatility, simplicity, low cost and high efficiency. The low-noise operation provides players with a better user experience, and the convenient disassembly and maintenance and greatly increased service life will make it more popular with sellers.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
