Description

Technical Field

[0001] This application relates to the field of entertainment system technology, and more particularly to a fully automatic card dealing device for playing cards or mahjong tiles. Background Technology

[0002] A fully automatic card dealing machine is a machine that can shuffle and deal cards. Currently, fully automatic card dealing machines in the industry are mainly divided into several categories. The first category is the boot-shaped fully automatic card dealing machine, which is mainly used in overseas card and board game entertainment venues. The second category is the table-type card dealing machine represented by Xuanhe, such as patent number CN222150864U, which is similar to the design concept of a fully automatic mahjong machine. It has a complex design and high production and maintenance costs. The third category is the small portable card dealing machine that is currently popular on the market. The disadvantage is that after each dealing, it needs to be moved from the middle position, and then moved back to the middle position for the next dealing, resulting in a poor user experience.

[0003] In the past, some manufacturers in the industry have tried to integrate card dealing machines into fully automatic mahjong tables, but they still use tabletop card dealing machines similar to those in Xuanhe, Zhejiang, which are based on fully automatic mahjong machines and involve creating a separate card dealing system, making the structure more complex.

[0004] In summary, the current centralized card and board game entertainment equipment on the market falls into three categories: First, portable card dealers, which need to be removed from the middle after each deal, resulting in a poor user experience; second, fully automatic mahjong machines, which can only play mahjong and not cards; and third, integrated mahjong and poker machines, but these have two independent hardware systems for mahjong and poker, leading to complex structures and high production, maintenance, and repair costs. Therefore, there is an urgent need in the market for a new type of card dealer to solve the numerous problems existing in the industry. Utility Model Content

[0005] The purpose of this application is to provide a card dealing machine to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0007] Compared with existing technologies,

[0008] A card dealing machine includes a card pressing mechanism, which includes a card pressing connecting rod and a card pressing plate. One end of the card pressing connecting rod is rotatably connected to the card pressing mechanism, and the other end is connected to the card pressing plate.

[0009] Preferably, the connection method between the pressure plate connecting rod and the pressure plate is either a fixed connection or a rotatable connection.

[0010] Preferably, it includes: an upper housing, a rotating base, and a rotating mechanism;

[0011] The upper shell and the rotating base are connected by a supporting mechanical rotating body;

[0012] The rotating mechanism includes a rotary motor and a rotary positioning device;

[0013] The rotary motor is located inside the upper housing and is connected to the rotating base in a transmission manner.

[0014] The upper shell contains a card compartment, which is equipped with the card pressing mechanism. The bottom of the card compartment is equipped with a card feeding mechanism. One side of the bottom of the card compartment has a card inlet, which is equipped with a card separating mechanism. Outside the card inlet is a card dispensing mechanism.

[0015] Preferably, the card storage compartment is provided with a card storage compartment cover on the upper part, and a card pressing rod hook is provided on the bottom surface of the card storage compartment cover.

[0016] Preferably, the card-splitting mechanism includes a card-splitting block disposed above the card inlet and a limiting piece disposed below the card inlet, wherein the gap between the card-splitting block and the limiting piece is the thickness of a card.

[0017] Preferably, the card feeding mechanism includes a card feeding motor and a card feeding roller that is drivenly connected to the card feeding motor, and the card feeding roller is installed at the bottom of the card compartment.

[0018] Preferably, the card-dispensing mechanism includes a card-dispensing motor, a card-dispensing rubber roller that is drivenly connected to the card-dispensing motor, and a driven rubber roller that is adapted to the card-dispensing rubber roller.

[0019] Preferably, the driven rubber roller is located above the card-dispensing rubber roller, and the card-dispensing motor and the card-feeding motor are located in front of and above the driven rubber roller.

[0020] Preferably, the limiting piece extends through the card inlet and between the card dispensing roller and the driven roller.

[0021] Preferably, the upper housing is provided with a circuit board, which contains a program for controlling the mahjong machine and / or the card dispensing mechanism. The circuit board is connected to the rotary motor, the rotary positioning device, the card feeding mechanism, and the card dispensing mechanism, respectively.

[0022] Compared with the prior art, this application has the following technical effects:

[0023] 1. Based on the existing mahjong machine, without altering any of its existing structure, a mahjong and card game integrated machine has been created. Functionally, this achieves a synergistic effect, combining the entertainment functions of both a mahjong machine and a card game machine. This significantly reduces costs. Compared to portable machines that require manual removal after each deal, this new machine automatically lowers itself under the table after dealing, greatly improving the user's gaming experience and entertainment value.

[0024] Since the invention of the fully automatic mahjong table in 1964, the design concept of the mahjong and poker integrated machine has always been to design a separate card dealing system inside the original mahjong integrated machine. The two operate independently, integrated into a single mahjong and poker machine. The shuffling, card delivery, and card dealing of the card machine have always been carried out on the table, resulting in an extremely complex structure, high cost, and high maintenance difficulty. Even the existing tabletop poker machines on the market currently use a similar approach, with shuffling, card delivery, and card dealing all operating on the table, resulting in an extremely complex structure, high cost, and high maintenance difficulty. To date, no one in the industry has modified the dice plate to enable the mahjong machine to also function as a mahjong and poker integrated machine, because the space on the dice plate is extremely limited, and conventional designs simply cannot realize the independent function of the card dealing machine. This application, within the original dice plate and its limited space of the fully automatic mahjong table, refines and combines each mechanism to enable it to realize the card dealing function, solving a technical problem that the industry has been trying to solve for many years without success.

[0025] 2. This equipment is simple in design, low in cost, ingenious in structure, and easy to maintain. It eliminates the need for a shuffling structure and directly uses program-controlled random card dealing to replace the shuffling function, which greatly simplifies the structure of the equipment and has unexpected technical effects.

[0026] 3. This equipment has strong compatibility. Since most mahjong machines on the market use universal product sizes and operating programs for their dice, this equipment only requires a software change to transform existing fully automatic mahjong machines into integrated mahjong and poker machines. Moreover, with the recent popularity of Guandan (a card game), more and more people are enjoying card games. Based on this, this application is expected to become a standard feature in future mahjong machine production and can upgrade existing mahjong machines to have integrated mahjong and poker functions, which will lead to great commercial success.

[0027] 4. The card dealing machine of this application has strong versatility. First, it can be compatible with the dice plate of a mahjong machine, transforming the mahjong machine into a mahjong and poker all-in-one machine. Second, with an external table and lifting mechanism, it can be used as a standalone tabletop poker machine. Moreover, it has a simple structure, low cost, and is easy to install, repair, and maintain. Third, with a base, it can be used as a standalone portable card dealing machine. The base and card dealing machine are designed to be detachable, making it easy to carry and suitable for different scenarios.

[0028] 5. The dice tray, also commonly known as the mahjong machine operating tray, mahjong machine lifting tray, or mahjong machine dice tray, is generally oval, but square or hexagonal shapes are also possible. The lower part is bowl-shaped. Converting it into a card-dealing machine within such a limited space requires careful consideration of the spatial arrangement of the card-dealing mechanism. First, program-controlled random card dealing replaces the shuffling structure, saving one-third of the space. Second, changing from vertical to horizontal card dealing, the motor is positioned diagonally above the card-dispensing roller and the driven roller, making the card-dispensing opening of the lower cover a conical surface, while the other three sides of the lower cover are vertical, all within the original dimensions of the mahjong machine lifting tray. Third, the rotating base only houses the rotating motor, making its overall structure smaller towards the bottom, still within the original dimensions of the mahjong machine lifting tray. Fourth, horizontal card dealing has a shorter card-dispensing stroke than vertical dealing, resulting in faster card dealing speed in the same amount of time, reducing waiting time. This application has fully considered the layout of each mechanism of the card-dealing machine, allowing it to be embedded in a dice tray with limited space, achieving unexpected technical benefits.

[0029] Through the above design, some structures in this entertainment system, such as the lifting mechanism of the dice plate, the existing buttons on the dice plate, and the electronic screen control system, are shared by the mahjong machine and the card dealing machine. This greatly reduces the number of structural components, makes full use of the equipment space, reduces production costs, facilitates installation and maintenance, improves the user experience, and has unexpected technical effects.

Therefore, they should not be construed as limitations on this application.

[0058] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0059] like Figures 1 to 24 As shown:

[0060] Example 1:

[0061] The card dealing machine is integrated into the existing mahjong machine's dice tray, using the existing dice tray cover, which has various control buttons required by both mahjong machines and card dealing machines.

[0062] A card compartment cover is located at the center of the face cover and is connected to the face cover by a spring-loaded rotating shaft. When the card compartment cover is closed, it is connected to the face cover by a buckle and a spring button. The main body of the card dealing machine is located in the cavity formed by the lower cover and the face cover of the card dealing machine.

[0063] The card pressing mechanism of the card dealing machine adopts the simplest spring pressing structure (not shown in the figure). When the card compartment cover is closed, the spring set on the card compartment cover applies a certain downward pressure to the card in the card compartment, so that the card feeding roller generates sufficient friction with the card in contact, thereby feeding the card out and ensuring smooth card feeding.

[0064] The main body of the card dealing machine consists of an upper shell, a card feeding mechanism, a card dispensing mechanism, a card separating mechanism, and a rotating mechanism.

[0065] The upper shell is mainly divided into three parts: one part is used as a playing card compartment, and the other two parts are used as a motor compartment and a PCB board compartment.

[0066] The card feeding mechanism consists of a card feeding motor and a card feeding roller, which is used to feed the cards in the card compartment to the card inlet. The card feeding roller is located at the bottom of the card compartment and is supported on the housing on both sides by bearings.

[0067] The card-feeding roller has flexible serrations arranged around its circumference to ensure smooth card feeding. At the card inlet, the cards are separated into individual cards by the combined action of the card-separating metal block and the card-dispensing limiting spring, and then dispensed from the card outlet.

[0068] The card-splitting mechanism consists of a card-dispensing limit steel plate and a card-splitting metal block. The vertical position of the card-splitting metal block can be adjusted appropriately. By adjusting the gap between the card-dispensing limit steel plate and the card-splitting metal block, only one card can pass through at a time, thus avoiding the dispensing of multiple cards at once.

[0069] The card-dispensing mechanism consists of a card-dispensing motor, a card-dispensing rubber roller, and a driven rubber roller. The card-dispensing rubber roller and its driven rubber roller, which drive the cards to be dispensed, are located at the bottom of the motor compartment and are supported on the housing on both sides by bearings.

[0070] The card-dispensing roller and the driven roller work together to ensure that the angle and force of the card dispensing are stable.

[0071] Both the card feeding motor and the card dispensing motor are located inside the motor compartment.

[0072] The card feeding motor and card feeding roller, as well as the card dispensing motor and card dispensing roller, are all driven by synchronous belt transmission. The two sets of synchronous belt transmission mechanisms and the corresponding synchronous pulleys are respectively set on both sides of the housing.

[0073] In this embodiment, the card-dispensing limiting steel sheet and the upper vertex of the card-feeding rubber roller are kept at the same level, so that when the card is dispensed, the card is horizontally delivered by the card-feeding rubber roller to the card-separating mechanism, and then to the card-dispensing mechanism.

[0074] The bottom of the card compartment has an installation slot that matches the card dispensing limit steel plate. If it needs to accommodate different card thicknesses, only a few different thicknesses of card dispensing limit steel plates need to be produced. By installing the corresponding thickness of the card dispensing limit steel plate according to the different card thicknesses, the equipment can be adapted to different card thicknesses. No other parts of the equipment need to be modified, and the installation slot has pre-drilled screw holes, making it very convenient to disassemble and replace the card dispensing limit steel plate.

[0075] Alternatively, the thickness of the card-dispensing limiting steel sheet can be fixed, while the card-separating metal blocks can be designed in different sizes, so that the gap between the card-separating metal block and the card-dispensing limiting steel sheet is the thickness of a card, to accommodate cards of different thicknesses. In this case, only different models of card-separating metal blocks need to be replaced to adapt to cards of different thicknesses for dealing. It is easy to install, low in cost, and convenient to maintain, making the card dealing machine more adaptable and able to accommodate cards of different thicknesses on the market.

[0076] Alternatively, the metal card slot can be designed with only one universal size. By adjusting the installation height of the metal card slot, the gap between the metal card slot and the card dispensing limit steel plate can be adjusted. The outer side of the upper wall of the card inlet of the card compartment can be provided with a card slot mounting groove. The card slot and the card slot mounting groove are detachably connected. For example, washers of different thicknesses can be set at the bottom of the metal card slot and the card slot mounting groove. By adjusting the washers of different thicknesses, the installation height of the metal card slot can be adjusted, thereby achieving adaptive adjustment.

[0077] Spatial layout of the card-dealing and card-playing mechanisms

[0078] The card-dispensing limit steel plate and the card-separating metal block are centrally located at the card inlet, which does not take up space but achieves a good card-separating effect. Moreover, they are easy to disassemble and assemble, facilitating production, assembly, installation and maintenance.

[0079] The card-splitting metal block is installed on the outer center of the facade where the card inlet is located. This makes full use of the space between the card inlet and the card dispensing roller and driven roller, which can shorten the distance between the card inlet and the card dispensing roller and driven roller. In other words, the card-splitting metal block does not increase the distance between the card inlet and the card dispensing mechanism, resulting in a smaller and shorter size compared to conventional card dealing machines.

[0080] The card-dispensing roller and the driven roller are designed with two sets of card-dispensing rollers and driven rollers running through a single steel shaft. The two sets of card-dispensing rollers and driven rollers are symmetrically arranged on the left and right sides. This provides space for the extension of the card-dispensing limiting steel plate. The card-dispensing limiting steel plate passes through the card inlet from the card compartment and extends beyond the vertical cross-section of the card-dispensing roller, improving the smoothness and stability of card delivery. Moreover, the same principle makes full use of the space between the card inlet and the card-dispensing roller and driven roller.

[0081] Of course, when both the card-dispensing roller and the driven roller are a single piece, there is still some space between the tangents and the intersection of the two circles of the card-dispensing roller and the driven roller. The card-dispensing limit steel plate can extend through the tangent to the position close to the intersection of the card-dispensing roller and the driven roller, which improves the stability of the card conveying.

[0082] The rotating mechanism is located at the bottom of the housing and includes a rotary motor, a synchronous belt and pulley, and ball bearings.

[0083] The outer steel ring of the ball bearing is fixedly connected to the main body of the card dealer, which is also the upper shell of the main body of the card dealer. It is also fixedly connected to a set of synchronous pulleys in the synchronous belt and synchronous pulley of the rotating mechanism. The inner steel ring of the ball bearing is fixedly connected to the rotating base. A rotary motor is installed in the rotating base located below the main body of the card dealer (below the lower cover). The rotary motor drives the main body of the card dealer to rotate circumferentially through a set of synchronous belts.

[0084] A light sensor is installed below the motor compartment at the card dispensing port to detect whether a card has been successfully dispensed, thereby controlling the number of cards dispensed or monitoring whether all cards have been dispensed.

[0085] A Hall sensor is installed in the circumferential direction at the rotating mechanism position at the bottom of the card dealer to sense the rotation angle of the rotating mechanism, thereby controlling the card dealing direction of the card dealer.

[0086] The control PCB board of the card dealing machine is integrated with the original control PCB board of the mahjong machine.

[0087] The PCB board is connected to the Hall sensor, light sensor, rotary motor, card feeding motor, card dispensing motor, touch screen or display screen on the card compartment cover, control buttons on the cover, all circuit control systems of the original mahjong machine, such as the lifting motor of the dice plate lifting mechanism, and the actuators of the entire set of shuffling, stacking, and card feeding mechanisms of the mahjong machine. Since fully automatic mahjong tables or mahjong machines are existing technology, they will not be elaborated on here.

[0088] In actual use, the user can arrange the cards face down, shuffle and stack them, and then place them in the card holder. After setting the dealing mode, the card dealing machine executes the operation according to control commands. The rotating mechanism adjusts the dealing position, the card feeding mechanism feeds the cards, the card separating mechanism separates the cards, and the card dispensing mechanism deals the cards. After cards are dealt to one position, the rotating mechanism adjusts the dealing position to the next position and continues the operation until cards are dealt to all positions.

[0089] In the above process, it is also possible for the user to simply arrange the cards face down, stack them, and put them into the card holder without shuffling them. In this case, the pre-set software program will control the cards to be dealt in a random manner, thereby achieving a certain degree of shuffling function.

[0090] The irregular card dealing rules of this application can be preset in the circuit board program with some irregular card dealing methods. For example, the rules for dealing cards in all four positions are as follows: the first set of card dealing position rules is 0°, 180°, 360°, 270°, 90°; the second set of card dealing position rules is 0°, 90°, 180°, 360°, 270°; and the third set of card dealing position rules is 360°, 270°, 0°, 90°, 180°. The three sets of rules are run alternately until the number of cards dealt in each position meets the preset requirements. The number of cards dealt in each position is a random number from 0 to 4, thus achieving irregular card dealing. Taking 0 cards means rotating to the corresponding card dealing position, but not dealing any cards, which means the number of cards dealt is 0. Then, it rotates to the next card dealing position and performs the card dealing action. The above are just examples. In actual operation, various irregular methods can be built into the program of the circuit board to realize irregular card dealing for different numbers of cards, such as two positions, six positions, and eight positions.

[0091] The preset number of cards to be dealt refers to the total number of cards to be dealt as preset through the display screen and buttons, or the number calculated by the system by setting the total number of cards and the number of players. For example, if there are 54 cards and 2 people are playing, each person needs to be dealt 27 cards, and 27 cards is the preset number of cards to be dealt.

[0092] In this embodiment, the card dealer is powered by an external direct-plug power supply, such as the existing power supply system of an automatic mahjong machine that uses an external direct-plug power supply, without the need for a separate power supply.

[0093] When the card dealer in this embodiment is powered by an external direct-plug power supply, such as the original power supply system of an automatic mahjong machine that is powered directly by an external direct-plug power supply, the power supply to the PCB board, Hall sensor, light sensor, and motor requires corresponding wires to be routed to the corresponding power supply devices through the hollow pipes reserved in the rotating base and the main body of the card dealer. Therefore, it is necessary to control the PCB board of the card dealer to rotate 360° and then rotate 360° in the opposite direction to reset each time the card is dealt, and repeat this process. This way, the wires will not twist into a rope due to continuous rotation and break. In addition, a lower cover baffle is set at one corner of the rotating base. When the card is dealt 360°, a rotating base baffle matching the lower cover baffle is set at the corresponding position of the upper shell of the main body of the card dealer, so that it cannot rotate in the same direction again.

[0094] During the research and development debugging phase, the applicant discovered that sometimes when rotating and throwing cards, the travel distance of the thrown cards would be shorter. After repeated debugging, it was found that the program settings were performing both the throwing and rotation actions. The applicant then optimized the program so that the throwing action would only be performed when the rotation action reached a certain direction and stopped. At this time, one card might be thrown, or the instruction might require throwing N cards one by one. The rotation action would only be performed after the throwing action in a certain stopping direction was completely completed. This prevents the rotation from starting before the cards are completely thrown or the throwing action from starting before the rotation has completely stopped, so that the thrown cards do not have a short travel distance and fall into the mahjong machine's card pusher inlet below the card dealer.

[0095] By optimizing the program steps, the card dealing process is smoother and the dealing process is more consistent, thus improving the stability of the card dealing.

[0096] Currently, the mainstream dice disk size on the market is as follows: the outer diameter of the top disc is 238mm, and the bottom disc gradually tapers to a total thickness of 50mm. A deck of 54 cards is 57mm-60mm wide and 87-98mm long, with a total thickness of about 20mm. Under such extreme dimensions, the structural layout of the card dealing machine needs to fully consider the layout of different structures. The card compartment deals cards horizontally, and a card dispensing roller and a driven roller are set outside the card dispensing port. The card dispensing motor and the card feeding motor are located above the card dispensing roller and the driven roller. The card separating mechanism does not increase the space and also acts as a bridge between the card feeding mechanism and the card dispensing mechanism. The card dispensing motor and the card feeding motor are located above the card dispensing roller and the driven roller.

[0097] This application fully considers the original dice board's saucer-shaped structure, which gradually tapers from top to bottom. Figure 18 As can be seen, the card-dispensing motor and the card-feeding motor of this application are positioned diagonally above the driven rubber roller. The driven rubber roller is located precisely to the left of the shortest distance plane between the card-dispensing motor and the card-feeding motor and the card-dispensing rubber roller. This design shortens the distance between the card-dispensing rubber roller and the card-dispensing motor and the card-feeding motor, making the overall card-dispensing machine more compact and smaller in size. The card-dispensing port is located to the right of the shortest distance plane between the card-dispensing motor and the card-feeding motor and the card-dispensing rubber roller. The space of this motor compartment includes the card-dispensing motor and the card-feeding motor, the card-dispensing rubber roller and the driven rubber roller, and the card-dispensing port. This arrangement maximizes the use of space, allowing it to fit the original dice disk's saucer-shaped structure, which gradually tapers from top to bottom. Figure 2 As can be seen, the card-playing opening is located on an inclined surface of the same size as the original dice plate.

[0098] The usage process of this device is as follows: First, arrange the playing cards face down so that they are facing the same direction. Open the card compartment cover, place the cards face down into the card compartment, close the card compartment cover, and switch the device to card mode using the control buttons. At this time, the lifting plate rises, and the device deals cards according to the preset number of cards and the number of players. At this time, it operates on a random card dealing system, where the rotation to each player's position is random, and the number of cards dealt each time is random, until all the preset number of cards have been dealt to all players. Once the card dealing is complete, the lifting plate lowers into the table, and the players begin to play cards. When a player wants to play mahjong, they only need to press the button to switch to mahjong mode, which will then enter mahjong machine mode. Since the operation of the mahjong machine is existing technology, it will not be described in detail here.

[0099] The specific method of dealing cards includes the following steps:

[0100] S1. Deal the mahjong tiles;

[0101] S2. Deal the cards;

[0102] S3, switch between executing S1 or S2.

[0103] In S2, the card dealing is random.

[0104] The aforementioned irregular card dealing means that the cards arrive at the predetermined position randomly and / or the number of cards dealt each time is random;

[0105] The number of cards dealt at the predetermined position is greater than or equal to one card and less than or equal to the total number of cards pre-dealt at the predetermined position.

[0106] The rotation rule of the entertainment system is that after rotating 360°, it needs to rotate 360° in the opposite direction to return to the starting point, and so on in a repeated cycle.

[0107] The card dealing action is performed only after each time the card reaches the predetermined position.

[0108] The predetermined position is an N-divided position of 360°.

[0109] Example 2:

[0110] This card dealing machine uses a card-pressing lever instead of a spring. The card-pressing lever consists of a card-pressing connecting rod and a card-pressing plate, which can be integrated or separate. When they are separate, a rotating mechanism can be installed at the connection point between the card-pressing connecting rod and the card-pressing plate. When the card-pressing plate presses on the card, it always remains horizontal. The length of the card-pressing plate can be close to the length of the card, and the width is half the width of the card. Moreover, it presses the card in the center, which ensures that the pressure on the card is even and facilitates the smooth dispensing of the card.

[0111] A card pressing rod hook is provided at the corresponding position of the card storage cover. When the card storage cover is opened to place cards, the card pressing rod can be stuck on the card storage cover. When the card placement is completed, the card pressing rod is disengaged from the card pressing rod hook and pressed onto the cards.

[0112] Embodiment 3:

[0113] The card dealing machine is powered by a storage battery, and it can be powered without using the original power supply system of the automatic mahjong machine that uses an external direct plug-in power supply. Instead, only when the card dealing machine is not working, its storage battery needs to be powered.

[0114] The storage battery can be charged by reserving a charging port or by wireless charging. That is, the storage battery used is a storage battery adapted to wireless charging, and a wireless charger is set inside the fully automatic mahjong table integrated with the card dealing machine or a separate card dealing table formed by a separate support for the card dealing machine. In this way, as long as there is external power supply, the storage battery can be continuously charged. If the lifting mechanism connecting the card dealing machine inside the fully automatic mahjong table or a separate card dealing table formed by a separate support for the card dealing machine is also equipped with an independent storage battery, even if there is no external power supply temporarily, the self - contained storage battery can provide power, enabling it to carry out card entertainment activities.

[0115] When powered by a storage battery, the part above the rotating base of the card dealing machine is powered by the storage battery. At this time, the control of the rotating motor and the lifting motor自带的升降电机的控制可以通过无线通信的方式,由PCB板的程序进行无线控制。此时,可以不用拘泥于实施例1的每次发牌旋转完成360°后,需要反向旋转360°复位,也无需设置实施例1的下盖挡板配套的转动底座挡板,发牌机可以随意旋转,娱乐性更强,体验感更佳,此时需要对发牌机的控制PCB板的程序做适应性调整即可。

[0116] Embodiment 4: A layer of dust - proof pad is provided at the bottom of the card storage of the card dealing machine. Except for exposing the flexible convex teeth of the card feeding rubber roller, the support skeleton and the card - discharging limit steel sheet, all other parts at the bottom are covered. This design is both beautiful and prevents dust from falling in, thereby increasing the service life of the card dealing machine and reducing the usage failure rate of the card dealing machine.

[0117] Several support skeletons and card - discharging limit steel sheet installation parts are provided at the bottom of the card storage. Their heights are slightly lower than that of the card feeding rubber roller. First, after the card - discharging limit steel sheet is installed, it is exactly horizontal with the card feeding rubber roller, making each card sent out in a horizontal state. Second, because the height of the support skeleton is slightly lower than that of the card feeding rubber roller, the support skeleton not only plays a role in supporting the cards to keep them horizontal but also does not affect the card feeding rubber roller from providing friction to send out the cards, thus ensuring the smoothness and fluency of card dealing.

[0118] Such as Figure 5 It should be noted that there seems to be an error in the description "麻将机自带的升降电机的控制可以通过无线通信的方式,由PCB板的程序进行无线控制." in the original text, where "自带的升降电机的控制可以通过无线通信的方式" is an incomplete expression. I have translated it as accurately as possible based on the existing text. If you can provide more accurate and complete information, it will be helpful for more accurate translation.As shown, the support frame of this application includes four supports, two of which are evenly distributed behind the card feeding roller, and the other two are distributed on both sides in front of the card feeding roller. The mounting bosses of the card dispensing limit steel sheet are arranged in the center. This mounting boss not only facilitates the installation of the card dispensing limit steel sheet, but also ensures that the card dispensing limit steel sheet and the support frames on both sides can ensure that the cards pass smoothly through the card separating mechanism and enter the corresponding card dispensing roller and driven roller. The support frame saves raw materials, eliminates the need for a solid bottom for support in the card storage, provides support, and reduces friction, thus allowing the cards to pass smoothly from the card feeding mechanism to the card separating mechanism and then to the card dispensing mechanism.

[0119] Example 5: Because a rotating mechanism with a synchronous belt and synchronous pulley is provided between the rotating base and the upper shell of the card dealing machine body, a certain space is formed outside the synchronous belt and synchronous pulley without any structure, causing the card dealing machine to shake violently when the button is pressed. Therefore, in this example, three sets of support rollers are arranged outside the rotating wheel of the rotating base. The support rollers consist of a support base fixed to the rotating base and rollers that can roll around the support base. In this way, when the button is pressed, because three sets of support rollers are evenly distributed in the space outside the synchronous belt and synchronous pulley, there is no gap difference between the rotating base and the card dealing machine body. When the control button is pressed, the card dealing machine body will no longer shake. In addition, when the card dealing machine body rotates, it can rotate freely based on the rotation of the rollers.

[0120] Example 6: The card compartment has grooves on three sides to make it easy to put your fingers in and take out the cards. This design is in line with the ergonomic design concept. When the cards are put in and need to be taken out, it is more convenient to take out the cards, for example, with your thumb, index finger and middle finger.

[0121] Example 7: The synchronous belts and synchronous pulleys of the card feeding mechanism, card dispensing mechanism, and rotating mechanism in Example 1 can be replaced by gear meshing transmission or chain transmission, etc., to achieve the same technical effect as described in this application.

[0122] Example 8: Adding a layer of sound insulation cotton to the outside of the existing motor reduces the noise of the card dealing machine, achieving a good noise reduction effect and improving the user's entertainment experience.

[0123] Example 9: The card dealer can be equipped with a through-hole slip ring to transmit power from the fixed position to the rotating position. For example, the MT series through-hole slip ring of Moflon can be used. This eliminates the need to rotate 360° in the opposite direction to reset after each 360° rotation as required in Example 1. It also eliminates the need for the rotating base baffle that matches the lower cover baffle in Example 1. The card dealer can rotate freely, making it more entertaining and providing a better user experience. At the same time, the program of the control PCB board of the card dealer can be adjusted accordingly.

[0124] Example 10: This application is not limited to the structures provided in the above embodiments. For example, the card dealing machine corresponding to the patent with authorization announcement number CN220193952U can be integrated into the dice tray of a mahjong machine. The structure of the dice tray can be adaptively expanded, and the two programs can be connected and interconnected. It is also possible to modify the dice tray of the mahjong machine. Compared with the aforementioned embodiments, the compatibility and scalability are slightly worse. The table hole for embedding the dice tray in the mahjong machine needs to be adaptively expanded to accommodate the integration of the modified card dealing machine and the dice tray. However, it is still possible to achieve that some structures in this entertainment system, such as the lifting mechanism of the dice tray, the existing buttons of the dice tray, the electronic screen and other control systems, can be shared by the mahjong machine and the card dealing machine. This greatly reduces the number of structural components, makes full use of the space of the equipment, reduces production costs, facilitates installation and maintenance, improves the user experience, and has unexpected technical effects.

[0125] Example 11: In this example, the rotating mechanism is located at the bottom of the housing and includes a rotary motor, a synchronous belt and synchronous pulley of the rotating mechanism, and ball bearings.

[0126] The inner steel ring of the ball bearing is fixedly connected to the main body of the card dealing machine, which is also the upper housing of the main body. The outer steel ring of the ball bearing is fixedly connected to the rotating base, and also fixedly connected to a set of synchronous pulleys in the synchronous belt and synchronous pulleys of the rotating mechanism. A rotary motor is installed in the upper housing of the main body of the card dealing machine. This rotary motor drives the main body of the card dealing machine to rotate circumferentially via a set of synchronous belts. This axial movement occurs because the outer steel ring of the ball bearing is fixedly connected to the rotating base. When the motor rotates, it rotates around a set of synchronous pulleys corresponding to the stationary outer steel ring. At this time, the main body of the card dealing machine rotates circumferentially, and the rotary motor inside the upper housing also rotates along with it.

[0127] The biggest difference from Embodiment 1 is that the rotary motor is located inside the upper housing. If the rotary motor and gearbox of Embodiment 1 are used directly, they can be located on the other side of the card compartment, symmetrical to the card feeding motor and the card dispensing motor. If only the rotary motor is used, the gearbox is removed, and the rotary motor can be set vertically downwards, allowing it to be located on any three sides other than the card dispensing port. This design allows the rotating base to be designed very thin, with the overall card dealing machine only slightly thicker than a deck of cards. With other structural changes similar to Embodiment 1, the overall performance is better than that of Embodiment 1, and the device is thinner and lighter, providing more possibilities for further compatibility and scalability. This embodiment can also be modified into a tabletop card dealing machine or used directly as a portable card dealing machine. Compared to existing tabletop card dealing machines, this application has a simpler structure, lower production costs, and is easier to maintain and install. When used directly as a portable card dealing machine, the thinner rotating base results in a thinner overall size, providing a better user experience.
