Description

Technical Field

[0001] The utility model relates to the technical field of entertainment equipment, and more specifically, to a card-dealing mechanism capable of preventing card jams. Background Art

[0002] In existing card-dealing mechanisms, especially in entertainment equipment such as automatic poker machines and mahjong machines, the stability and accuracy of the card-dealing process are crucial. When traditional card-dealing mechanisms convey playing cards, problems such as card jams, multiple cards, and missing cards often occur. These problems not only affect the normal operation of the equipment but also the user experience.

[0003] To solve these problems, various improved card-dealing mechanisms have emerged on the market. However, these mechanisms still have certain defects in their structural design and operating principles. For example, when some mechanisms convey playing cards, due to insufficient friction between the card-conveying wheel and the playing cards, the playing cards slide or fall during the conveying process, resulting in card jams. Additionally, when some mechanisms limit the conveying position of playing cards, due to unreasonable design of the limit components, the playing cards are prone to shifting during the conveying process, affecting the accuracy of card dealing. Summary of the Utility Model

[0004] In view of the above problems, the utility model proposes a card-dealing mechanism capable of preventing card jams. By optimizing the surface structure of the card-conveying wheel, setting a double card-conveying wheel to improve the conveying stability, and adopting a unique limit component and card-pressing component, the problems of card jams, multiple cards, and missing cards existing in traditional card-dealing mechanisms are effectively solved.

[0005] To achieve the above purpose, the specific technical solutions adopted by the utility model are as follows:

[0006] The card-dealing mechanism capable of preventing card jams according to the utility model includes a card-feeding component, a limit component, and a card-pressing component;

[0007] The limit component includes a frame body and a lower limit block, and the lower limit block is fixedly installed on the frame body;

[0008] The card-pressing component includes a card-pressing seat, a guide post, a pressing rod, and a card-pressing wheel. The card-pressing wheel is movably connected to the card-pressing seat. One end of the guide post is fixedly connected to the housing, and the other end is fixedly connected to the card-pressing seat. The pressing rod is slidably connected to the card-pressing seat, and the pressing rod is slidably connected to the guide post through an elastic member;

[0009] An upper limit block corresponding to the lower limit block is provided on the card-pressing seat. The upper limit block and the lower limit block can form a card-feeding channel at intervals. This card-feeding channel is used to receive the playing cards conveyed by the card-feeding component. The widths of both the upper limit block and the lower limit block are smaller than the width of the playing cards.

[0010] Preferably, the card feeding assembly includes a second power device, a card transferring wheel, and a card feeding wheel, and the card transferring wheel and the card feeding wheel are respectively drivably connected to the second power device.

[0011] Preferably, the second power device is configured as a second motor.

[0012] Preferably, the card transferring wheel and the card pressing wheel are respectively drivably connected to the second motor through a second gear set and a third gear set.

[0013] Preferably, a first worm of the second motor and a second worm of the second motor are respectively arranged at two ends of the second motor, and the first worm of the second motor and the second worm of the second motor are respectively meshed and connected to the second gear set and the third gear set.

[0014] Preferably, a second installation groove is provided on the frame body, and the lower limit block is fixedly installed on the second installation groove.

[0015] Preferably, the lower limit block is fixedly installed on the second installation groove through a support rod and a nut.

[0016] Preferably, the elastic member is configured as a spring.

[0017] Preferably, the surface of the card transferring wheel is provided with serrated corrugations.

[0018] Preferably, the serrated corrugations include 16 convex points designed on the surface and evenly distributed at different angles of the roller, and a plurality of smaller transverse stripe teeth are arranged at intervals.

[0019] Preferably, two card transferring wheels are provided.

[0020] Preferably, both the first worm of the second motor and the second worm of the second motor are configured as worms.

[0021] Preferably, the lower limit block is configured in a wedge shape.

[0022] Preferably, the end of the upper limit block is configured with an arc transition shape.

[0023] Preferably, a sleeve hole is provided on the card pressing seat, and one end of the guiding column is sleeved with the sleeve hole.

[0024] Preferably, the pressing rod is fixedly connected to the card pressing seat through a connecting column.

[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] After the upper limit block and the lower limit block in the utility model are fixed, according to the design structure, there is a limit gap in the middle that can pass a playing card. This gap can only pass a single playing card, so as to prevent the problems of excessive cards and card jams. This limit does not need to be adjusted and can be achieved by assembling according to the design principle, which is simple and convenient.

[0027] In the utility model, the widths of the upper limit block and the lower limit block are both smaller than the width of the playing card, so that the bent playing card can still pass smoothly even when it is warped on both sides.

[0028] In the utility model, the surface of the card transfer wheel is provided with serrated corrugations. By increasing the friction with the playing card, the playing card is more stable during the transfer process. At the same time, the serrated corrugations adopt a design of 4 evenly distributed larger horizontal stripe teeth and several smaller horizontal stripe teeth arranged between the larger horizontal stripe teeth, so that the card transfer wheel can better grasp the playing card when rotating, preventing it from sliding or falling. In addition, the present invention adopts a design of double card transfer wheels, and through the coordinated work of the two card transfer wheels, the stability of transferring playing cards is further improved.

[0029] In the design of the limit component and the card pressing component of the utility model, the utility model adopts a unique structure. Among them, the limit component includes a frame body and a lower limit block, and the lower limit block is fixedly installed on the installation groove through a support rod and a nut, making the installation convenient. The card pressing component includes a card pressing seat, a guide post, a pressing rod and a card pressing wheel. Through the action of the guide post and the spring, the card pressing seat can be adjusted up and down according to the thickness of the playing card, so as to ensure that the playing card is always in the correct position during the transfer process. At the same time, the setting of the card pressing wheel can further increase the friction with the playing card and prevent it from moving.

[0030] In summary, the card-dealing mechanism capable of preventing card jams proposed by the utility model has been optimized and improved in both structural design and operation principle, effectively solving the problems of card jams, excessive cards, and missing cards in the traditional card-dealing mechanism, and improving the stability and accuracy of the card-dealing mechanism.

[0048] The following further illustrates the present utility model through specific examples.

[0049] Embodiment

[0050] This embodiment provides a convenient-to-use card dealing machine, as Figure 1 shown, including a base body 10 and a housing 20, and the housing 20 is rotatably connected to the base body 10 to adjust the card dealing direction.

[0051] Specifically, as Figure 3 、 6 、7 shows, a card dealing bin 21 is formed on the housing 20, a first installation groove 211 is provided on the card dealing bin 21, and a card pressing rod 212 is rotatably connected to the first installation groove 211. The card pressing rod 212 is used to press the stack of cards placed in the card dealing bin 21 to prevent the cards from getting out of order during the transmission of playing cards, thereby improving the stability of card dealing.

[0052] More specifically, a rotating shaft 2121 is provided at the tail of the card pressing rod 212, and the card pressing rod 212 is rotatably connected to the first installation groove 211 through the rotating shaft 2121.

[0053] More specifically, a placing wheel 213 is provided on the card placing bin to pad up the stack of cards.

[0054] Specifically, a card storage bin 22 is connected to one side of the housing 20.

[0055] More specifically, the card storage bin 22 and the housing can be fixedly connected by adhesive; alternatively, a receiving groove 221 is provided on the card storage bin 22, and a plug-in member 23 is provided on the side wall of one side of the housing 20. The receiving groove 221 and the plug-in member 23 can be plugged together to achieve the detachable connection between the card storage bin 22 and the housing 20.

[0056] Specifically, as Figure 8 shown, a card outlet 24 is provided on the housing 20, and the card outlet 24 is communicated with the card sending bin.

[0057] Specifically, a control panel 25 is provided on the other side of the housing 20 for controlling whether to start card dealing and for controlling the card dealing direction.

[0058] This embodiment also provides a card dealing mechanism that can prevent card jams. A card dealing mechanism is provided inside the housing 20, and the card dealing mechanism includes a card sending component 30, a limiting component 40, and a card pressing component 50.

[0059] More specifically, the card sending component 30 includes a second motor 31, a card transmitting wheel 32, and a card sending wheel 33. The card transmitting wheel 32 is drivably connected to the second motor 31 through a second gear set 34, and the card sending wheel 33 is drivably connected to the second motor 31 through a third gear set 35.

[0060] More specifically, the surface of the card transfer wheel 32 is provided with serrated corrugations 321 for increasing the friction with the playing cards.

[0061] More specifically, the serrated corrugations 321 include 16 convex points designed on the surface and evenly distributed at different angles of the roller, and several smaller transverse stripe teeth are arranged at intervals.

[0062] More specifically, two card transfer wheels 32 are provided to improve the stability of conveying the playing cards.

[0063] More specifically, a first worm 311 of the second motor and a second worm 312 of the second motor are respectively arranged at both ends of the second motor 31. The first worm 311 of the second motor is meshed and connected with the second gear set 34, and the second worm 312 of the second motor is meshed and connected with the third gear set 35. In addition, the first worm 311 of the second motor and the second worm 312 of the second motor can be at both ends of a coaxial shaft.

[0064] More specifically, both the first worm 311 of the second motor and the second worm 312 of the second motor are arranged as worms.

[0065] More specifically, the card transfer wheel 32 passes through the housing 20 and protrudes in the card dealing bin 21.

[0066] More specifically, the limiting component 40 includes a frame body 41 and a lower limiting block 42. A second installation groove 43 is provided on the frame body 41, and the lower limiting block 42 is fixedly installed on the second installation groove 43.

[0067] More specifically, the lower limiting block 42 is fixedly installed on the second installation groove 43 through a support rod 44 and a nut 45.

[0068] More specifically, as Figure 2 、 5 shown, the card pressing component 50 includes a card pressing seat 51, a guide post 52, a pressing rod 53, and a card pressing wheel 54. An upper limiting block 511 corresponding to the lower limiting block 42 is provided on the card pressing seat 51. A card feeding channel is formed by the interval between the upper limiting block 511 and the lower limiting block 42. The widths of both the upper limiting block 511 and the lower limiting block 42 are smaller than the width of the playing card, so that the bent playing card can still pass smoothly through the card feeding channel formed by the interval between the upper limiting block 511 and the lower limiting block 42 when the two sides are warped and deformed.

[0069] The pressing card wheel 54 is movably connected to the card pressing seat 51. One end of the guiding column 52 is fixedly connected to the housing 20, and the other end of the guiding column 52 is fixedly connected to the card pressing seat 51. The pressing rod 53 is slidably connected to the card pressing seat 51, and the pressing rod 53 is slidably connected to the guiding column 52 through a spring 55. When the playing card enters the card feeding channel, the upper limit block 511 is pushed open, driving the card pressing seat 51 to move slightly upward. At this time, the pressing rod 53 follows the card pressing seat 51 to move slightly upward, compressing the spring 55 and sliding on the guiding column 52.

[0070] The operation process of the card dealing mechanism is as follows: Stack the playing cards on the placing wheel 213 in the card dealing bin 21. Start the second motor 31, and both the card transferring wheel 32 and the card feeding wheel 33 rotate. The single playing card in contact with the card transferring wheel 32 is transferred by the card transferring wheel 32 to the card feeding channel, which is formed by the lower limit block 42 and the upper limit block 511 at intervals. This interval is just larger than the thickness of a single playing card but smaller than the thickness of two playing cards to ensure that the number of cards dealt each time is a single playing card.

[0071] At this time, the pressing card wheel 54 moves slightly upward and can press the playing card tightly.

[0072] It should be noted that pressing the playing card tightly improves the stability of the card dealing system by preventing the playing card from moving around.

[0073] After that, the playing card contacts the card feeding wheel 33 and is transferred by the card feeding wheel 33 to the card dealing opening to deal the playing card.

[0074] More specifically, the lower limit block 42 is set in the shape of a wedge.

[0075] More specifically, the end of the upper limit block 511 is set in an arc transition shape.

[0076] More specifically, a socket hole 512 is provided on the card pressing seat 51, and one end of the guiding column 52 is sleeved in the socket hole 512 to achieve the fixed connection between the guiding column 52 and the card pressing seat 51.

[0077] More specifically, the pressing rod 53 is slidably connected to the card pressing seat 51 through a connecting column 56.

[0078] Specifically, as Figure 4As shown, a rotating mechanism 60 is provided inside the housing 20. The rotating mechanism 60 includes a first motor 61, an upper mounting housing 62, a lower mounting housing 63, and a first gear set 64. The first motor 61 is mounted on the upper mounting housing 62. The first motor shaft of the first motor 61 passes through the upper mounting housing 62 and is drivably connected to the first gear set 64. The first gear set 64 is mounted in a chamber formed by the upper mounting housing 62 and the lower mounting housing 63. The first gear set 64 is key-connected to the lower mounting housing 63. A mounting plate 26 is provided at the bottom of the housing 20. A sleeve 27 is provided on the mounting plate 26. The sleeve 27 is rotatably connected to the mounting plate 26. A driving hole 271 corresponding to the lower mounting housing 63 is provided on the sleeve 27. The sleeve 27 is connected to the turntable 11. The turntable 11 is rotatably connected to the seat body 10.

[0079] The working mode is as follows: When the first motor 61 is started, the first motor shaft drives the first gear set 64 to rotate. The first gear set 64 drives the lower mounting housing 63 to rotate. The lower mounting housing 63 drives the sleeve 27 and the turntable 11 to rotate relative to the seat body 10 by being inserted into the driving hole 271, thereby enabling the housing 20 to rotate and finally changing the direction of the card-dealing opening.

[0080] More specifically, the lower mounting housing 63 is snap-connected to the upper mounting housing 62.

[0081] More specifically, a clamping groove 631 is provided on the lower mounting housing 63, and a clamping buckle 621 corresponding to the clamping groove 631 is provided on the upper mounting housing 62. The clamping groove 631 and the clamping buckle 621 can be snap-connected.
