Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of entertainment systems, in particular to a full-automatic card dispensing device for paper cards or mahjong tiles. BACKGROUND

[0002] A full-automatic card dispenser is a machine capable of shuffling and dispensing cards. Currently, full-automatic card dispensers in the industry are mainly divided into several categories. The first category is a boot-type full-automatic card dispenser mainly used in foreign chess entertainment venues. The second category is a table-type card dispenser represented by Xuanhe, such as patent No. CN222150864U, which is similar to the design concept of a full-automatic mahjong machine. The design is complex, and the production and maintenance costs are high. The third category is a small portable card dispenser popular on the market. The disadvantage is that the dispenser needs to be moved away from the middle after each dispensing, and needs to be moved back to the middle position for the next dispensing, which is not good for user experience.

[0003] In the past, some manufacturers in the industry have tried to integrate a card dispenser into a full-automatic mahjong table, but still use a table-type card dispenser similar to Zhejiang Xuanhe, which is a paper card dispensing system based on a full-automatic mahjong machine. The structure is more complex.

[0004] In summary, the current centralized chess entertainment equipment on the market has the following problems. The first type is a portable card dispenser, which needs to be moved away from the middle after each dispensing, resulting in poor user experience. The second type is a full-automatic mahjong machine, which can only play mahjong and cannot play paper cards. The third type is a mahjong and poker integrated machine, but the two sets of mahjong and poker hardware systems operate independently, resulting in a complex structure and high production, maintenance and repair costs. Therefore, there is an urgent need for a new type of card dispenser to solve the many problems in the industry. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to provide a card compartment and a card dispenser to solve the problems mentioned in the background.

[0006] To solve the above technical problems, the present application provides the following technical solutions:

[0007] Compared with the prior art,

[0009] Preferably, three facades of the card compartment except the card dispensing port are provided with grooves.

[0010] Preferably, the groove is in the shape of a circular arc.

[0011] A card dispenser, comprising: an upper housing, a rotating base, and a rotating mechanism;

[0012] The upper housing and the rotating base are connected by a support mechanical rotating body.

[0013] The rotating mechanism comprises a rotating motor and a rotating positioning device;

[0014] The rotating motor is arranged in the upper housing and is in transmission connection with the rotating base;

[0015] The upper housing is provided with the card storage as claimed in any one of the preceding claims, the card storage is provided with the card pressing mechanism, the bottom of the card storage is provided with a card feeding mechanism, one side of the bottom of the card storage is provided with a card inlet, the card inlet is provided with a card separating mechanism, and the card inlet is externally provided with a card outlet mechanism.

[0016] Preferably, the card separating mechanism comprises a card separating block arranged above the card inlet and a limiting piece arranged below the card inlet, and the gap between the card separating block and the limiting piece is the thickness of a card.

[0017] Preferably, the card feeding mechanism comprises a card feeding motor and a card feeding rubber roller in transmission connection with the card feeding motor, and the card feeding rubber roller is arranged at the bottom of the card storage.

[0018] Preferably, the card outlet mechanism comprises a card outlet motor, a card outlet rubber roller in transmission connection with the card outlet motor, and a driven rubber roller matched with the card outlet rubber roller.

[0019] Preferably, the driven rubber roller is arranged above the card outlet rubber roller, and the card outlet motor and the card feeding motor are arranged above the driven rubber roller.

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

[0021] Preferably, the upper housing is internally provided with a circuit board, the circuit board is internally provided with a program for controlling the mahjong machine and / or the card feeding mechanism, and the circuit board is respectively connected with the rotating motor, the rotating positioning device, the card feeding mechanism and the card outlet mechanism.

[0022] Compared with the prior art, the mahjong machine has the following technical effects:

[0023] 1. On the basis of the original mahjong machine, without changing any existing structure of the mahjong machine, a mahjong and card integrated machine is realized, and a one plus one is greater than two effect is realized in function, so that the entertainment device has the entertainment functions of the mahjong machine and the card machine. The cost is greatly reduced. Compared with the portable type, it does not need to be taken out every time. At present, the portable card feeder is placed in the middle to feed cards, and needs to be manually taken out after each card feeding. The card feeder of the present application will automatically descend to the table after card feeding, without the need to take it out every time like the portable card feeder, greatly improving the user's playing experience and entertainment experience.

[0024] Since the invention of the full-automatic mahjong table in 1964, the design idea of mahjong poker integrated machine has been to separately design a paper card dispensing system inside the original mahjong integrated machine, and the two run independently and are integrated into a mahjong poker integrated machine. The shuffling, card feeding and dispensing of the paper card machine have been running and working on the desktop, and the structure is complex, the cost is high, the maintenance is difficult, and even the existing table poker machine on the market also uses similar shuffling, card feeding and dispensing which run and work on the desktop, and the structure is complex, the cost is high, the maintenance is difficult. Up to now, no one in the industry has modified the dice disc to make the mahjong machine have the function of mahjong poker integrated machine. Because the space of the dice disc is limited, the conventional design cannot realize the independent function of the card dispenser. The present application arranges and combines each mechanism in the limited space of the original dice disc of the full-automatic mahjong table, so that the paper card dispensing function can be realized, and the technical problem that has been unable to solve for many years in the industry is solved.

[0025] 2、The device is simple in result, low in cost, ingenious in structure design, convenient in maintenance, does not set a shuffling structure, and directly uses a program-controlled irregular dispensing to replace the shuffling function, greatly simplifies the structure of the device, and has unexpected technical effects.

[0026] 3、The device has strong compatibility. Because most of the dice discs of the mahjong machines on the market are general product sizes and general operation programs, the device only needs to replace the software program, so that the original full-automatic mahjong machine can be modified into a mahjong poker integrated machine. Moreover, with the recent popularity of the egg crushing, more and more people like paper card games. Based on this, the present application is expected to be the standard configuration of mahjong machines in the future production, and can upgrade and modify the stock mahjong machine market to have the function of mahjong poker integrated machine, so that great success will be obtained in business.

[0027] 4、The card dispenser of the present application has strong extensibility. First, it can be compatible with the dice disc of the mahjong machine, and modify the mahjong machine into a mahjong poker integrated machine. Second, an external table body and lifting mechanism can be configured, which can be used as a separate table poker machine, and the structure is simple, the cost is low, and the installation, maintenance and maintenance are convenient. Third, a base can be matched, which can be used as a separate portable card dispenser. The base and the card dispenser are designed as a detachable structure, which is convenient to carry and can be applied to different scenes.

[0028] 5、Dice disc is also commonly known as mahjong machine operation disc, mahjong machine lifting disc, mahjong machine dice disc, generally oval, also square, hexagonal, etc., the lower part is bowl-shaped, in such limited space, it is necessary to fully consider the space arrangement of the card dispenser mechanism. First, the card dispensing mechanism is replaced by the card dispensing mechanism controlled by the program, which can save one third of the space, second, the vertical card dispensing is changed to horizontal card dispensing, the motor is arranged above the card dispensing rubber roller and the driven rubber roller, the lower cover dispensing port position is a conical surface, and the other three vertical surfaces of the lower cover are within the size range of the original mahjong machine lifting disc; Third, the rotating base is only provided with a rotating motor, so that the overall structure becomes smaller and smaller, and still reduces the size range of the original mahjong machine lifting disc; Fourth, compared with vertical card dispensing, horizontal card dispensing has short card dispensing stroke, fast card dispensing speed under the same time, and reduced card dispensing waiting time. The layout of each mechanism of the card dispenser is fully considered in the application, so that the dice disc can be embedded in a narrow space, and unexpected technical effects are obtained.

[0029] Through the above design, part of the structure in the entertainment system, such as the lifting mechanism of the dice disc, the existing keys of the dice disc, the control system of the electronic screen, is shared by the mahjong machine and the card dispenser, which greatly reduces the structure parts, fully utilizes the space of the equipment, reduces the production cost, and improves the user's experience. The installation, maintenance and use experience are improved, and unexpected technical effects are obtained. BRIEF DESCRIPTION OF DRAWINGS

[0059] As shown in Figures 1 to 24

[0060] Embodiment 1

[0061] The card dispenser is integrated in the existing mahjong machine dice tray, and the existing dice tray cover is used. Various control buttons required by the mahjong machine and the card dispenser are provided on the cover.

[0062] A card compartment cover connected by a spring rotating shaft is provided at the center position of the cover. When the card compartment cover is closed, it is connected with the cover through a buckle and a spring button. The main body of the card dispenser is arranged in the cavity formed by the lower cover of the card dispenser and the cover.

[0063] The card pressing mechanism of the card dispenser adopts the simplest spring card pressing structure (not shown in the figure). When the card compartment cover is closed, the spring provided on the card compartment cover gives the cards in the card compartment a certain downward pressure, so that the card feeding rubber roller and the contacted cards generate sufficient friction force, thereby feeding the cards out and ensuring the smoothness of the card feeding.

[0064] The main body of the card dispenser is composed of an upper shell, a card feeding mechanism, a card dispensing mechanism, a card distributing mechanism and a rotating mechanism.

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

[0066] The card feeding mechanism is composed of a card feeding motor and a card feeding rubber roller, which is used to feed the cards in the card compartment to the card inlet. The card feeding rubber roller is arranged at the bottom of the card compartment and supported on the shell through bearings on both sides.

[0067] ​The flexible convex teeth arranged in the circumferential direction of the card feeding rubber roller ensure the smoothness of card feeding. The card feeding opening is separated into a single card by the cooperation of the card separating metal block and the card feeding limiting spring sheet, and the card is sent out from the card feeding opening.

[0068] The card separating mechanism is composed of the card feeding limiting steel sheet and the card separating metal block. The position of the card separating metal block can be adjusted, and the gap between the card feeding limiting steel sheet and the card separating metal block is adjusted to allow only one card to pass at a time, so as to avoid sending multiple cards at a time.

[0069] The card feeding mechanism is composed of a card feeding motor, a card feeding rubber roller, and a driven rubber roller. The card feeding rubber roller and the driven rubber roller are arranged at the bottom of the motor compartment and supported on the shell through bearings on both sides.

[0070] The card feeding rubber roller and the driven rubber roller cooperate to ensure the stability of the angle and force of the card feeding.

[0071] The card feeding motor and the card feeding motor are arranged in the motor compartment.

[0072] The card feeding motor and the card feeding rubber roller, and the card feeding motor and the card feeding rubber roller are driven by synchronous belt transmission. The two sets of synchronous belt transmission mechanisms and the corresponding synchronous wheels are arranged on both sides of the shell.

[0073] In this embodiment, the upper vertex of the card feeding limiting steel sheet and the card feeding rubber roller is kept horizontal, so that the card face is horizontally fed by the card feeding rubber roller to the card separating mechanism and then to the card feeding mechanism.

[0074] An installation groove matched with the card feeding limiting steel sheet is arranged at the bottom of the card compartment. If it is necessary to adapt to different card thicknesses, only a few card feeding limiting steel sheets with different thicknesses need to be produced, and the card feeding limiting steel sheet with the corresponding thickness is installed according to the thickness of the different cards, so that the equipment can adapt to different card thicknesses. No other parts of other equipment need to be changed, and the installation groove is pre-drilled with screw holes, so that the card feeding limiting steel sheet can be easily disassembled and replaced.

[0075] The card feeding limiting steel sheet can also have a fixed thickness, and the card separating metal block can be designed in different sizes so that the gap between the card separating metal block and the card feeding limiting steel sheet is the thickness of a single card, corresponding to different thicknesses of cards. At this time, only the card separating metal block of different models needs to be replaced, which can adapt to different thicknesses of cards for card feeding, is easy to install, has low cost, is convenient to maintain and repair, and makes the card dispenser more adaptable to different thicknesses of cards on the market.

[0076] The metal card separating plate can also be designed in a general size, and the gap between the metal card separating plate and the card outlet limiting steel sheet can be adjusted by adjusting the installation height of the metal card separating plate. An installation groove for the card separating block can be arranged on the upper wall outside the card inlet. The card separating block and the installation groove are detachably connected. For example, different thickness of washers are arranged at the bottom of the metal card separating plate and the installation groove. The installation height of the metal card separating plate can be adjusted by adjusting the thickness of the washers, thereby achieving adaptive adjustment.

[0077] Spatial cooperation layout of card separating mechanism and card outlet mechanism

[0078] The card outlet limiting steel sheet and the card separating metal block are centrally arranged in the card inlet, do not occupy space, and have good card separating effect. Moreover, the card separating metal block is convenient to disassemble and assemble, and is convenient for production, assembly, installation and maintenance.

[0079] The card separating metal block is installed at the central outside of the vertical surface of the card inlet. In this way, the space between the card inlet and the card outlet rubber roller and the driven rubber roller is fully utilized, and the distance between the card inlet and the card outlet rubber roller and the driven rubber roller can be shortened. That is, the card separating metal block does not increase the distance between the card inlet and the card outlet mechanism, and the volume of the card dealer is smaller and shorter than that of the conventional card dealer.

[0080] The card outlet rubber roller and the driven rubber roller are designed to be penetrated by a steel shaft. The two sets of card outlet rubber rollers and driven rubber rollers are symmetrically arranged on the left and right sides, which reserves an extension space for the card outlet limiting steel sheet. The card outlet limiting steel sheet penetrates the card inlet from the card box and extends beyond the vertical section of the card outlet rubber roller, thereby improving the smoothness and stability of the card feeding. Moreover, according to the same principle, the space between the card inlet and the card outlet rubber roller and the driven rubber roller is fully utilized.

[0081] Of course, in the case that the card outlet rubber roller and the driven rubber roller are a whole, the tangent and intersection of the two circles of the card outlet rubber roller and the driven rubber roller still leave a certain space. The card outlet limiting steel sheet can extend to the position close to the intersection of the card outlet rubber roller and the driven rubber roller after penetrating the section formed by the tangent, thereby improving the stability of the card feeding.

[0082] The rotating mechanism is arranged at the bottom of the shell and includes a rotating motor, a synchronous belt and a synchronous wheel of the rotating mechanism, and a ball bearing,

[0083] The outer steel ring of the ball bearing is fixedly connected with the upper shell of the card dealer main body and a synchronous wheel of the synchronous belt and the synchronous wheel of the rotating mechanism. The inner steel ring of the ball bearing is fixedly connected with the rotating base. In this way, the rotating motor is arranged in the rotating base below the card dealer main body (below the lower cover). The rotating motor drives the card dealer main body to rotate in the circumferential direction through the synchronous belt.

[0084] A light sensor is arranged at the position of the card outlet below the motor compartment, for sensing whether the cards are smoothly sent out, so as to control the number of cards sent out, or monitor whether the cards are sent out completely, etc.

[0085] A Hall sensor is arranged at the position of the rotating mechanism at the bottom of the card dealer, in the circumferential direction, for sensing the rotating angle of the rotating mechanism, so as to control the card sending direction of the card dealer, etc.

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

[0087] The PCB is connected with the Hall sensor, the light sensor, the rotating motor, the card sending motor, the card sending motor, the touch screen or display screen on the card compartment cover, the control buttons on the face cover, the control system of all circuits of the original mahjong machine, the lifting motor of the lifting mechanism of the dice disc, the complete set of card shuffling, stacking and sending mechanism of the mahjong machine, etc.

[0088] In actual use, the user can arrange the back of the cards to face up, and after shuffling and stacking the cards, put them into the card compartment; set the card sending mode, and the card dealer executes the operation according to the control instruction, adjusts the card sending direction by the rotating mechanism, sends the cards by the card sending mechanism, separates the cards by the card separating mechanism, and sends the cards by the card sending mechanism. After the cards in one direction are sent out, the rotating mechanism adjusts the card sending direction to the next direction, and continues the related operation and card sending. Until all the cards in all directions are sent out.

[0089] In the above process, if the user only arranges the back of the cards to face up, and stacks the cards after putting them into the card compartment, but does not shuffle the cards, it is also acceptable. In this case, the software program is controlled according to the preset software program, and the cards are sent out in a random manner, so as to realize a certain degree of shuffling function.

[0090] The random dispensing rule of the application can preset some random dispensing modes in the program of the circuit board, for example, the rule that four positions need to be dispensed is that the first group dispensing position rule is 0°, 180°, 360°, 270°, 90° operation, the second group dispensing position rule is 0°, 90°, 180°, 360°, 270°, and the third group dispensing position rule is 360°, 270°, 0°, 90°, 180°, and the three groups are alternately operated until the dispensing number of each position meets the preset requirement. The dispensing number of each position each time is a random number from 0 to 4, and the dispensing is performed, so as to realize random dispensing. Taking 0 as an example, the corresponding dispensing position is rotated, but the dispensing is not performed, that is, the dispensing number is 0, and then the next dispensing position is rotated and the dispensing action is performed. The above is only an example, and in actual operation, various random modes can be built into the program of the circuit board to realize random dispensing of two positions, six positions, eight positions and other different dispensing numbers.

[0091] Each preset dispensing number refers to the total number of dispensing preset through the display screen and the key, or the number obtained by the system calculation through setting the total number of cards and the number of players, for example, 54 cards, 2 players, and 27 cards for each player, that is, the preset dispensing number.

[0092] The power supply of the embodiment, the dispensing machine is powered by an external direct insertion power supply, for example, directly using the original power supply system of the automatic mahjong machine of the external direct insertion power supply, without providing a power supply.

[0093] When the dispensing machine of the embodiment is powered by an external direct insertion power supply, for example, directly using the original power supply system of the automatic mahjong machine of the external direct insertion power supply, the power supply of the PCB, the hall sensor, the light sensor and the motor needs corresponding wires to be laid on the corresponding electrical devices through the hollow pipeline reserved in the rotating base and the dispensing machine body, so the program of the dispensing machine PCB is needed to control the reverse rotation of 360° after the completion of 360° of each dispensing rotation, and the dispensing is repeatedly performed, so that the wires cannot be twisted into a rope due to continuous rotation, thereby being disconnected, and the lower cover baffle is arranged at a corner position of the rotating base, when the dispensing rotation of 360° is completed each time, the rotating base baffle matched with the lower cover baffle is arranged at the corresponding position of the upper shell of the dispensing machine body, so that it cannot rotate in the same direction again.

[0094] The applicant found that sometimes the rotating and throwing cards, the throwing card travel will be shorter, after repeated debugging found that, because the program settings, the program executes the throwing card action, and the rotating action, the applicant then optimized the program, when the rotating action rotates to a certain direction and stops, the throwing card action is executed, at this time, it may throw a card, or the instruction requires a card to throw N cards, when the throwing card action is completed in a certain stop direction, the rotating action is executed, so as to prevent the card from being thrown out when the rotating action is not completed, and the throwing card action is executed when the rotating action is not completely stopped, so as to prevent the card from being thrown out when the rotating action is not completed, and the throwing card action is executed when the rotating action is not completely stopped, so as to prevent the card from being thrown out when the rotating action is not completed.

[0095] Through the step optimization of the program, the card distribution is more smooth, and the card distribution is consistent, which improves the stability of the card distribution.

[0096] At present, the mainstream size of the dice disc on the market is that the upper disc has an outer diameter of 238mm, and the disc gradually shrinks to the bottom with a thickness of 50mm. A deck of 54 cards has a width of 57mm-60mm and a length of 87-98mm, and the thickness of 54 cards together is about 20mm. Under such extreme size, the structure layout of the card dispenser needs to fully consider the layout of different structures. The card warehouse is horizontally distributed, the card outlet is provided with a card outlet rubber roller and a driven rubber roller, the card outlet motor and the card feeding motor are arranged above the card outlet rubber roller and the driven rubber roller, the card distribution mechanism plays a bridge role between the card feeding mechanism and the card distribution mechanism without increasing the space, and the card outlet motor and the card feeding motor are arranged above the card outlet rubber roller and the driven rubber roller.

[0097] The present application fully considers that the original dice disc is a flying saucer type structure gradually shrinking from top to bottom, Figure 18 As can be seen, the card outlet motor and the card feeding motor are arranged obliquely above the driven rubber roller, and the driven rubber roller is arranged on the left side of the shortest distance surface of the card outlet rubber roller and the card outlet motor and the card feeding motor. Such design shortens the distance between the card outlet rubber roller and the card outlet motor and the card feeding motor, so that the whole card dispenser becomes more compact and smaller in size. The card outlet is located on the right side of the shortest distance surface of the card outlet motor and the card feeding motor and the card outlet rubber roller. The space of the motor warehouse includes the card outlet motor and the card feeding motor, the card outlet rubber roller and the driven rubber roller, and the card outlet. Such arrangement maximizes the use of space, so that it can be adapted to the flying saucer type structure gradually shrinking from top to bottom of the original dice disc, Figure 2 As can be seen, the card outlet is located on the same size inclined surface of the original dice disc.

[0098] The use process of the device is as follows: first, arrange the playing cards in one direction with the front and back sides in order, open the card bin cover, place the cards into the card bin with the front side facing down, close the card bin cover, switch the device to the card mode through the control button, at this time the lifting disc is raised, the device distributes cards according to the preset number of cards and the number of people, at this time the cards are distributed in a random manner, the randomness is that the rotation to each person's position is random, the number of cards distributed each time is random, until the preset number of cards of all people is distributed, the distribution is completed, the lifting disc is lowered into the tabletop, and the players start playing cards, when the players want to play mahjong, only need to switch the mahjong mode through the button, at this time the mahjong machine mode is entered, because the mahjong machine distributes mahjong in a manner known in the art, which will not be described here.

[0099] The specific card distribution method comprises the following steps,

[0100] S1, distributing mahjong;

[0101] S2, distributing cards;

[0102] S3, switching to execute S1 or S2.

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

[0104] The random distribution is that the arrival at the predetermined position is random or / and the number of cards distributed each time is random.

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

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

[0107] Each time the predetermined position is reached, the card distribution action is performed.

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

[0109] Embodiment 2:

[0110] The card distribution machine is provided with a card pressing rod instead of a spring pressing card. The card pressing rod comprises a card pressing connecting rod and a card pressing piece, which can be integrated or in a split structure. When they are in a split structure, a rotating mechanism can be arranged at the connecting position of the card pressing connecting rod and the card pressing piece. When the card pressing piece is pressed on the card, it always maintains a horizontal state. The size and length of the card pressing piece can be close to the length of the card, and the width is half the width of the card, and the card is pressed in the middle. In this way, the card pressing force is uniform, which is more beneficial to the smooth distribution of the card.

[0111] In the corresponding position of the card bin cover, a card pressing rod hook is arranged, so that when the card bin cover is opened to put cards, the card pressing rod can be clamped on the card bin cover, and when the card putting is completed, the card pressing rod is unhooked from the card pressing rod hook and pressed on the cards.

[0112] Embodiment 3:

[0113] The mahjong machine is provided with a battery for power supply, and can not be powered by the original power supply system of the automatic mahjong machine using external direct power supply, but only needs to power the battery when the mahjong machine is not working.

[0114] The battery charging can be performed in the reserved charging port mode, or in the wireless charging mode, that is, the battery used is adapted to wireless charging, and a wireless charger is arranged in the mahjong table integrated with the mahjong machine or the separate mahjong table supporting the mahjong machine, so that the battery can be continuously charged as long as the external power supply is supplied. If the lifting mechanism connected to the mahjong machine in the automatic mahjong table or the separate mahjong table supporting the mahjong machine is also provided with an independent battery, even if there is no external power supply temporarily, the self-provided battery can also provide power, so that the user can have a card game.

[0115] When the battery is used for power supply, the power supply of the part above the rotating base of the mahjong machine is provided by the battery, at this time, the rotation of the motor and the control of the lifting motor of the mahjong machine can be wirelessly controlled by the program of the PCB board. At this time, it is not necessary to reverse the rotation of 360° after each card dispensing rotation of 360° in embodiment 1, and it is also not necessary to set the rotating base baffle matched with the lower cover baffle in embodiment 1. The mahjong machine can be rotated at will, which is more entertaining and has better experience. At this time, the program of the control PCB board of the mahjong machine needs to be adjusted adaptively.

[0116] Embodiment 4: A dustproof pad is arranged at the bottom of the card bin of the mahjong machine, and all parts of the bottom except the flexible teeth of the card feeding rubber roller, the support frame and the card dispensing limiting steel sheet are covered, so that the design is not only beautiful but also prevents dust from falling into the card bin, thereby prolonging the service life of the mahjong machine and reducing the failure rate of the mahjong machine.

[0117] A plurality of support frames and card dispensing limiting steel sheet mounting portions are arranged at the bottom of the card bin, and the heights of the support frames and the card dispensing limiting steel sheet mounting portions are slightly lower than that of the card feeding rubber roller. On the one hand, the card dispensing limiting steel sheet mounting portion is arranged to be horizontal with the card feeding rubber roller after installation, so that each card is in a horizontal state when being fed out. On the other hand, the height of the support frame is slightly lower than that of the card feeding rubber roller, so that the support frame supports the card to keep it horizontal and does not affect the friction provided by the card feeding rubber roller to feed out the card, thereby ensuring the smoothness and fluency of the card dispensing.

[0118] As Figure 5As shown, the support framework of the present application includes 4, two of which are evenly distributed behind the card feeding rubber roller, and the other two are distributed on both sides in front of the card feeding rubber roller. The installation boss of the card limiting steel sheet is arranged in the middle. In this way, the installation boss facilitates the installation of the card limiting steel sheet, and the card limiting steel sheet and the support framework on both sides can ensure that the cards pass through the card distribution mechanism smoothly and enter the corresponding card feeding rubber roller and driven rubber roller. The support framework not only saves raw materials and makes the bottom of the card compartment not need a real bottom for support, but also reduces friction, so that the cards can pass smoothly from the card feeding mechanism to the card distribution mechanism to the card feeding mechanism.

[0119] In the embodiment 5, three groups of support rollers are arranged outside the rotating wheel of the rotating base. The support rollers are composed of a support base fixed to the rotating base and a roller that can roll around the support base. In this way, when the pressing key is operated, the rotating base and the main body of the card dealer have no gap difference, and the main body of the card dealer will not shake when the control key is pressed. In addition, the main body of the card dealer can rotate freely based on the rotation of the roller when it rotates.

[0120] In the embodiment 6, the card compartment is provided with a groove for conveniently putting the cards in and taking them out with fingers. This design conforms to the ergonomic design concept. When the cards need to be taken out, for example, the cards can be taken out more conveniently with the thumb, index finger and middle finger.

[0121] In the embodiment 7, the synchronous belt and synchronous wheel of the card feeding mechanism, card feeding mechanism and rotating mechanism in the embodiment 1 can be replaced by gear meshing transmission or chain transmission, which can also achieve the technical effects of the present application.

[0122] In the embodiment 8, a layer of sound insulation cotton is added outside the existing motor to reduce the noise of the rotating card dealer, which can achieve good mute effect and improve the entertainment experience of the user.

[0123] In the embodiment 9, the card dealer can be provided with a via hole slip ring to transmit power from a fixed position to a rotating position. For example, the MT series via hole slip ring of Moflon can be used. In this way, the card dealer can be rotated randomly without the need to reverse rotation by 360° after each card dealing rotation by 360° in the embodiment 1, and the rotating base baffle matched with the lower cover baffle in the embodiment 1 is also not needed. The card dealer can be rotated randomly, which is more entertaining and has better experience. At the same time, the program of the control PCB board of the card dealer can be adjusted adaptively.

[0124] Embodiment 10: The present application is not limited to the structure provided in the above embodiments, for example, the card dealer corresponding to the patent with the publication number CN220193952U is integrated into the dice tray of the mahjong machine, the structure of the dice tray is adaptively enlarged, the programs of the two are connected and communicated, and the modification of the dice tray of the mahjong machine can also be implemented. Compared with the foregoing embodiments, only the compatibility and expansion are slightly changed, the table hole of the mahjong machine embedded with the dice tray needs to be adaptively enlarged to adapt to the integration of the modified card dealer and the dice tray, but the control system of part of the structure in the present entertainment system, such as the lifting mechanism of the dice tray, the existing keys of the dice tray, and the electronic screen, can still be shared by the mahjong machine and the card dealer, which greatly reduces the structural components, fully utilizes the space of the equipment, reduces the production cost, and is convenient for installation and maintenance, improves the user experience, and has unexpected technical effects.

[0125] Embodiment 11: The rotating mechanism of the present embodiment is arranged at the bottom of the shell, including a rotating motor, a synchronous belt and a synchronous wheel of the rotating mechanism, and a ball bearing,

[0126] The inner steel ring of the ball bearing is fixedly connected with the upper shell of the card dealer main body, and the outer steel ring of the ball bearing is fixedly connected with the rotating base and a group of synchronous wheels of the rotating mechanism. In this way, the rotating motor is installed in the upper shell of the card dealer main body, and drives the card dealer main body to rotate circumferentially through a group of synchronous belts. The axial movement is that the outer steel ring of the ball bearing is fixedly connected with the rotating base, and the motor rotates around the corresponding group of synchronous wheels of the fixed outer steel ring. At this time, the card dealer main body rotates circumferentially, and the rotating motor arranged in the upper shell also rotates together.

[0127] The biggest difference from embodiment 1 is that the rotating motor is arranged in the upper shell. If the rotating motor and the gearbox of embodiment 1 are directly used, they can be arranged on the other side of the card warehouse opposite to the card feeding motor and the card output motor. If only the rotating motor is used and the gearbox is removed, the rotating motor can be arranged vertically downward, and then it can be arranged on any other three sides except one side of the card output port. Such a design makes the rotating base very thin, and the whole card dealer is only a little thicker than a deck of cards. Compared with the overall use effect of embodiment 1, the device becomes lighter and thinner, which provides more possibilities for the further compatibility and expansibility of the device. The present embodiment can also be modified into a table type card dealer and directly used as a portable card dealer. Compared with the existing table type card dealer, the structure of the present application is simpler, the production cost is lower, and the installation and maintenance are more convenient. When the rotating base is designed to be very thin, the size of the present application is thinner, which brings better operation experience to the user.
