Description

Technical Field

[0001] The present invention relates to the technical field of card dealing machines, and in particular to a card dealing machine. Background Art

[0002] Poker, a common recreational tool, is widely loved by the public for its diverse gameplay and appeal to all ages. However, after a round, players must organize, shuffle, and deal the cards themselves. To reduce this time, various machines have emerged to replace manual dealing, significantly enhancing the poker experience.

[0003] There are three main parts to the implementation of card dealing machines on the market: card-discharging structure, rotation control, and transmission method.

[0004] Among existing card-dispensing mechanisms, some use a card-pressing mechanism to increase friction between the cards and the rollers (e.g., CN115845352A - an automatic card-delivering machine), some utilize a double row of rollers coordinated with upper and lower rollers at the card-dispensing port (e.g., CN220193953U - a card-delivering machine), and some rely on a spring at the bottom to lift the cards and allow friction between the upper rollers to release the cards from above (e.g., CN115364466A - an automatic card-delivering machine). These mechanisms increase friction between the card-dispensing wheel and the cards to facilitate card delivery. However, in actual card-delivering, due to friction between the bottom card and the penultimate card, as well as an excessively large delivery channel, two cards are often delivered at once. Utility Model Content

[0005] Aiming at the above problems, the present utility model provides a card dealing machine.

[0006] The technical solutions adopted by this utility model are as follows:

[0007] A card dealing machine includes a card dealing box having a card bin, a card dealing channel and a card flying wheel. The rear end of the card dealing channel is a card inlet connected to the card bin, and the front end of the card dealing channel is located at the card dealing port exposed at the front end of the card dealing box. The card bin has a bottom bin plate, and the card flying wheel is exposed at the front of the bottom bin plate so as to deliver cards by friction. The machine also includes a downward pressure baffle that can move up and down, the downward pressure baffle is located above the card flying wheel, and a gap is formed between the lower end of the downward pressure baffle and the rim of the card flying wheel. The gap is used for inserting a single card, and the single card enters the card dealing channel through the gap.

[0008] This application uses a downward pressure baffle to squeeze the card inlet of the card dealing channel. The cards will not slide into the card dealing channel due to gravity. The front edge of the bottom card can enter the gap and lift the downward pressure baffle (the card dealing machine can adapt to cards of different thicknesses). The raised downward pressure baffle can block the second to last card and other cards. The first to last card enters the card dealing channel under the drive of the flying wheel, realizing single card flying.

[0009] In actual use, the downward pressure baffle can squeeze the cards through elastic parts or its own gravity.

[0010] In one embodiment of the present invention, the gap is 0.3 mm-0.8 mm.

[0011] In one embodiment of the present invention, a notch is formed at the lower end of the downward pressure baffle, corresponding to the flying card wheel.

[0012] In actual use, the gap can be formed by removing material to avoid interference between the flying wheel and the downward pressure baffle.

[0013] In one embodiment of the present invention, a limit plate is provided on the front side of the card bin, and the limit plate is used to limit the downward pressing limit position of the downward pressing baffle to prevent the downward pressing baffle from being overly pressed downward.

[0014] In one embodiment of the present invention, the rear edge of the lower end of the downward pressure baffle has a bevel or arc-shaped guide angle.

[0015] Setting the guide angle can provide guidance, so that the first card can smoothly enter the gap and lift the downward pressure baffle.

[0016] In one embodiment of the present invention, the guide angle is in an arc shape, and the radius of the arc of the guide angle is between 0.5 mm and 11.2 mm.

[0017] In one embodiment of the present invention, an elastic pressing mechanism is further included for imparting elastic pressing force to the pressing baffle.

[0018] In one embodiment of the present invention, the elastic downward force is between 0.2N and 1.2N.

[0019] In one embodiment of the present invention, the elastic pressing mechanism includes a slider, an adjusting screw and a spring;

[0020] The front end of the card bin has a mounting side plate, and the mounting side plate is provided with a vertical slide groove;

[0021] The slider is fixed on the downward pressure baffle or is integrally formed with the downward pressure baffle, and the downward pressure baffle is slidably arranged in the slide groove through the slider;

[0022] The mounting side plate is provided with an internal thread, the adjusting screw is screwed onto the internal thread, and both ends of the spring are respectively against the slider and the adjusting screw. By rotating the adjusting screw forward or reversely, the elastic force exerted on the downward pressure baffle can be adjusted.

[0023] In one embodiment of the present invention, the card compartment further includes a cover plate rotatably mounted at the front end thereof, and the downward pressure baffle is slidably mounted on the cover plate.

[0024] The beneficial effects of the present invention are as follows: the present application uses a downward pressure baffle to squeeze the card inlet of the card dealing channel, and the cards will not slide into the card dealing channel due to gravity. The front edge of the bottom card can enter the gap and lift the downward pressure baffle. The lifted downward pressure baffle can block the second to last card and other cards, and the first to last card enters the card dealing channel under the drive of the flying wheel, thereby realizing single card flying.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0041] In the description of this application, it should be noted that the terms "inner" and "outer" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended solely to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0042] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0043] The present invention will be described in detail below with reference to the accompanying drawings.

[0044] Example 1

[0045] like Figure 1-11 As shown, this embodiment provides a silent card dealing machine based on joystick interaction and idle gear drive, including a card dealing box 1, an idle gear card dealing mechanism 2, a rotating mechanism 3, a downward pressure baffle 4, an elastic downward pressure mechanism 5 and a joystick interaction control system 6.

[0046] The card delivery box 1 includes a card compartment 11 and a card delivery channel 12. The rear end of the card delivery channel 12 is a card inlet 121 connected to the card compartment 11, and the front end of the card delivery channel 12 is a card delivery port 122 exposed at the front end of the card delivery box 1. In this embodiment, the left and right side walls of the card delivery box 1 corresponding to the card compartment 11 are transparent panels, allowing users to see the card delivery process from both sides, satisfying the user's psychological need for fairness in card games. The bottom panel of the card bin 11 is arranged in a shape that is low in the front and high in the back. Since the card rolling wheel 26 needs to protrude from the middle of the bottom panel, it is bound to cause the cards to tilt backward or forward. In the case of the cards tilting backward (referring to the situation where the middle of the cards is lifted by the card rolling wheel, and when the cards are unbalanced, the rear end of the cards is pressed downward and the front end is lifted upward, which often occurs in the prior art), the front end of the cards is lifted to a certain height, which may cause the front end of the cards to abut against the downward pressure baffle 4. Therefore, the middle part of the bottom panel in this embodiment is designed to be concave (concave), dividing the bottom panel into a bottom front and a bottom front. The bottom front panel 111 and the bottom rear panel 112 have a smaller inclination angle with respect to the horizontal plane than the bottom rear panel 112. The card roller 26 protrudes upward at the junction of the bottom front panel and the bottom rear panel (or the rear end of the bottom front panel or the front end of the bottom rear panel). Alternatively, the rear portion of the upper surface of the bottom panel is provided with multiple wedge-shaped blocks, each of which is lower in front and higher in back. The upper surfaces of the multiple wedge-shaped blocks lie on a common inclined plane, which is considered the bottom rear panel 112. The card roller 26 protrudes upward at the front end of this inclined plane. It should be noted that the concave design can be variously employed and is not limited to the two specific forms described above. In this embodiment, the orientation is defined as "front" with respect to the card dealing port 122. Generally, the inclination angle of the bottom front panel 111 is 4-7 degrees, and the inclination angle of the bottom rear panel 112 is 8-12 degrees. In this way, when the playing card slides from the back to the front, the playing card is lower at the front and higher at the back, and the horizontal inclination angle of the playing card changes from large to small (for example, gradually changes from 8 degrees to 5 degrees). During the change of the inclination angle of the playing card, the front end of the playing card has an upward tilting force, thereby pushing up the downward pressure baffle 4.

[0047] The idler gear card dealing mechanism 2 is located within the card dealing box 1 and comprises a card-flying motor 21, a fixed card-flying shaft 22, a card-flying wheel 23, a card-rolling motor 24, a fixed card-rolling shaft 25, and a card-rolling wheel 26. The card-flying motor 21 is located within the card dealing box 1, with a card-flying gear mounted on its motor shaft. The card-flying shaft 22 is fixed to each of the two brackets 27 on the left and right sides of the card dealing box 1. The fixed card-flying shaft 22 is a metal, non-rotatable shaft. A large through-hole is provided at the axis of the card wheel 23, and bearings (generally two, one at each end) are spaced apart in the through-hole (generally at both ends of the through-hole). The bearing sleeve is mounted on the card fixing shaft 22, thereby ensuring that the card wheel 23 makes almost no sound when rotating. A circle of teeth is provided in the middle of the card wheel 23, and the card wheel 23 directly meshes with the card gear through the teeth, thereby reducing the number of transmission stages and providing conditions for reducing the overall volume of the card dealing machine. Both sides of the teeth of the card wheel 23 are prismatic structures, and a rubber sleeve is provided on the outer surface of the prismatic structure. The rubber sleeve is elastically mounted on the prismatic structure, so that no adhesive or the like is required. By providing the rubber sleeve, the friction with the cards can be effectively increased. The card wheel 23 is directly meshed with the card gear, so that the card motor 21 can directly drive the card wheel 23 to rotate. There is no need to set a special multi-stage transmission system like the card dealing machine in the prior art (noise is generated at multiple positions), which effectively reduces noise; and the sliding friction (between the finger wheel and the shaft sleeve) in the prior art is changed to rolling friction, which further reduces noise (when the bearing is very good, the noise generated during rotation is almost inaudible); due to the use of a "one-to-one" transmission method (not one motor drives multiple wheels), the rated power of the motor becomes smaller, and the use of a low-power motor further reduces noise. The card wheel 23 is exposed at the front of the bottom front panel (correspondingly, a window is provided at the front of the bottom front panel) so that the cards are discharged by friction. The card rolling motor 24, the card rolling fixed shaft 25, and the card rolling wheel The structure of the card-rolling wheel 26 is identical to that of the card-rolling motor 21, the card-rolling fixed shaft 22, and the card-rolling wheel 23. The inner sides of each end of the card-rolling wheel 26 are rotatably mounted on the card-rolling fixed shaft 25 via at least one bearing. The card-rolling fixed shaft 25 is fixed to a bracket within the card-dealing box. The motor shaft of the card-rolling motor 24 is equipped with a card-rolling gear. A circle of teeth is located in the middle of the card-rolling wheel, which directly meshes with the card-rolling gear. The teeth of the card-rolling wheel are formed on either side of a prismatic structure with a rubber sleeve overlying the prismatic structure. However, the card-rolling wheel 26 protrudes from the junction of the bottom front panel 111 and the bottom rear panel 112. In this embodiment, the teeth of the card-rolling wheel 23 and the card-rolling wheel 26 are located in the middle, and the rubber sleeves on both sides are of equal length. This ensures symmetrical balance during operation, preventing shaking and vibration caused by unbalanced force on the left and right sides, which can cause noise.

[0048] During operation, the card-flying fixed shaft 22 and the card-rolling fixed shaft 25 do not rotate, and it is the card-flying wheel 23 and the card-rolling wheel 26 that rotate. Since the card-flying wheel 23 and the card-rolling wheel 26 are rotatably mounted on the card-flying fixed shaft 22 and the card-rolling fixed shaft 25 via bearings, the noise generated when the card-flying wheel 23 and the card-rolling wheel 26 rotate is extremely small. At the same time, the card-flying motor 21 and the card-rolling motor 24 directly engage with the card-flying wheel 23 and the card-rolling wheel 26, eliminating the need for a multi-stage transmission system. This can further reduce noise and also reduce the overall size and weight of the card-dealing machine.

[0049] The rotating mechanism 3 includes a rotating base 31, a rotating motor 32, and a gyroscope 33. The rotating base is rotatably mounted on the bottom of the card dealing box 1. Both the rotating motor 32 and the gyroscope 33 are located within the card dealing box 1. The rotating motor 32 and the rotating base 31 are connected via a gear transmission. The gyroscope 33 is electrically connected to a processing unit 61. The processing unit 61 controls the operation of the rotating motor 32 based on the number of cards dealt and the rotation angle feedback from the gyroscope 33. Compared to the prior art method of using multiple baffles or optical signals to convert angles, the angle measured by the gyroscope 33 is more accurate, thus enabling more precise angle control in the card dealing machine of this embodiment. Furthermore, by eliminating the complex design of multiple baffles and replacing them with a single gyroscope 33 located within the card dealing box 1, the size of the card dealing machine is reduced.

[0050] Pressing baffle plate 4 is arranged at the front end of card storehouse 11, and pressing baffle plate 4 is in the top of flying card wheel 23, and there is a gap of 0.3-0.8mm between the lower end of pressing baffle plate 4 and the wheel rim of flying card wheel 23, and the cards promptly enter the card-discharging passage through the gap. Pressing baffle plate 4 has elastic downward force, and elastic downward force is between 0.2-1.2N. After playing cards enter this gap, pressing baffle plate 4 can be lifted up, so the card-delivering machine with this structure can be suitable for cards of different thicknesses. In the present embodiment, the lower end face of pressing baffle plate 4 is provided with notch 41, and this notch 41 adopts the mode of material removal processing to form, avoids flying card wheel 23 and pressing baffle plate 4 from interfering. In the present embodiment, the lower end trailing edge of pressing baffle plate 4 has arc-shaped guide angle 42, and the arc radius is between 0.5-11.2mm. A limit plate 14 is provided on the front side of the card bin 11. The limit plate 14 is used to limit the downward limit position of the downward pressure baffle 4 to prevent the downward pressure baffle 4 from being over-pressed. The downward pressure baffle 4 is used to squeeze the card inlet 121 of the card distribution channel 12, and the cards will not slide into the card distribution channel due to gravity. When the card rolling wheel 26 drives the bottom card to slide forward, the front edge of the bottom card hits the guide angle 42 of the downward pressure baffle 4; under the action of the gravity of the card stack, the angle structure of the bottom plate makes the middle of the bottom card slightly contact with the card rolling wheel 26; as the card rolling wheel 26 pushes the card forward a short distance, the bottom card follows the guide angle 42 of the downward pressure baffle 4 2 drills into the bottom of the downward baffle 4, and the pressure of the spring 53 increases, preventing other cards except the bottom card from sliding into the card distribution channel and causing card discharging problems; the downward baffle 4 presses the cards, causing the middle of the bottom card to bend slightly downward, and the penultimate card (and the cards above it because their edges are supported by the part above the guide angle of the downward baffle 4) does not touch the card rolling wheel, has no driving force, and will not enter the card distribution channel, so that only the bottom card enters the card distribution channel 12, and a single card will be ejected.

[0051] The elastic pressing mechanism 5 is disposed between the side of the pressing baffle 4 and the side wall of the card compartment 11. The elastic pressing mechanism 5 is used to provide the pressing baffle 4 with an elastic pressing force adjustable between 0.2-1.2N. Two elastic pressing mechanisms 5 are provided, and the two elastic pressing mechanisms 5 are symmetrically arranged on the left and right sides of the card inlet 121. The elastic pressing mechanism 5 can be of various forms, as long as it meets the above-mentioned functions. Optionally, the elastic downward pressure mechanism 5 includes a slider 51, an adjustment screw 52, ​​and a spring 53. The side wall of the card compartment 11 (which is a physical part of the card box 1 and can be referred to as a mounting side panel in this embodiment) is provided with a vertical slot 13, which is connected to the card compartment 11, and the two slots 13 are symmetrically arranged on the left and right sides of the card inlet 121. The slider 51 is fixed (can be integrally formed) to the side of the downward pressure baffle 4 and slides in the slot 13. The upper section of the slot 13 is provided with an internal thread (the cross section of the slot 13 is not necessarily circular, so the internal thread can be a circumferentially discontinuous thread). The adjustment screw 52 is screwed into the upper section of the slot 13. The spring 53 is arranged in the slot 13, with its two ends respectively abutting the slider 51 and the adjustment screw 52. By rotating the adjustment screw 52 forward or backward, the elastic force acting on the downward pressure baffle 4 can be adjusted, thereby adjusting the downward pressure on the downward pressure baffle 4.

[0052] In actual use, the elastic downward pressing mechanism 5 may not have an elastic force adjustment function. The elastic downward pressing mechanism 5 may be a spring, a torsion spring, etc., which cooperates with the downward pressing baffle to cause the downward pressing baffle to move downward. In specific embodiment 1, one end of the spring, torsion spring, etc. cooperates with the mounting side plate, and the other end cooperates with the downward pressing baffle.

[0053] The joystick interactive control system 6 is provided on the card dealing box 1 and includes a processing unit 61 and a joystick control unit 62 electrically connected to the processing unit 61, a display unit 63 and a confirmation unit 64. The processing unit 61 is pre-stored with mini-programs (such as mini-programs for card games such as Pai Gow, Dou Di Zhu, Shuang Kou, Bao Huang, etc., which can be selected in the card dealing mode); the card dealing mode, the number of dealers, the number of cards dealt, the number of bottom cards, the card dealing direction, and the increase or decrease of the number of dealers, the number of cards dealt and the number of bottom cards are selected through the joystick control unit 62. When selecting the card dealing direction, a long push (such as 1-2 seconds; in this embodiment, after the long push, the processing unit 61 will use the display unit 63 to display a progress bar, and the direction setting is completed after the progress bar is completed) is required. The joystick (when the joystick is set vertically, the direction in which it is pushed is the card dealing direction, so there is no need to repeat it) For example, when the joystick is tilted or close to the horizontal setting, when setting the card dealing direction, push the joystick down for "forward"), and the rest of the time, short pushes (such as 0.1-0.5s) of the joystick are sufficient; the processing unit 61 displays the relevant content selected or set by the joystick control unit 62 through the display unit 63 (referring to the selection of the card dealing mode, the number of dealers, the number of cards dealt, and the number of bottom cards), and the confirmation unit 64 is used to confirm the relevant operation of the joystick control unit or return to the previous menu; the processing unit 61 controls the operation of the idle gear card dealing mechanism 2 and the rotating mechanism 3 based on the card dealing mode, the number of dealers, the number of cards dealt, the number of bottom cards, and the card dealing direction, so as to deal cards to the user.

[0054] A joystick interactive control system 6 is used to set the dealing mode, number of dealers, number of cards dealt, number of bottom cards, and dealing direction. Compared with common information input methods such as buttons and knobs, this reduces the number of operation steps and time, makes the operation more intuitive, and reduces the complexity of the operation. In addition, as a module of the game console, the design of the joystick is similar to the entertainment of the cards.

[0055] A photoelectric signal sensor 65 is provided in the card dealing channel 12 and is electrically connected to the processing unit 61. The processing unit 61 controls the operation of the idle gear card dealing mechanism 2 and the rotating mechanism 3 based on the electrical signal of the photoelectric signal sensor 65, thereby forming a real-time closed-loop control mechanism.

[0056] like Figure 12 As shown, the licensing process is as follows:

[0057] Step S1, the flying card motor 21 rotates. The flying card motor 21 starts rotating 100ms in advance to ensure that the speed corresponding to the required card dealing distance is reached before the first card is dealt and to maintain a constant speed to ensure the flying card distance. In fact, the flying card motor 21 can reach a constant speed in a very short time after starting.

[0058] Step S2: Dealing the cards. The card rolling motor 24 begins rotating. Driven by the card flying motor 21 and the card rolling motor 24, the card passes through the card dealing channel 12, blocking the photoelectric signal sensor 65. As the card flies out of the card dealing port 122, the photoelectric signal sensor 65 turns on, and the card rolling motor 24 stops rotating. The time from when the card rolling motor 24 starts rotating to when it stops typically is about 30 milliseconds.

[0059] Step S3: Rotation. The rotation motor 32 begins rotating. The gyroscope 33 provides real-time feedback on the rotation angle. When the rotation angle reaches a set angle, the rotation motor 32 stops. To allow sufficient time for the rotation to flow out, the card rolling motor 24 typically stops for about 500ms.

[0060] Step S4, continuously repeating the above steps S2 and S3.

[0061] Step S5: Stop dealing cards. After the last card is dealt (the cards have been dealt), the card-flying motor 21 stops rotating, and the card-rolling motor 24 and the rotary motor 32 are no longer activated. If the photoelectric signal sensor 65 does not emit an electrical signal within three card-dealing cycles, it indicates that the cards have been dealt.

[0062] In the repeated step S2, if the photoelectric signal sensor 65 is still on after the card rolling motor 24 rotates for 1 second, it proves that there is no card in the card ejection chamber 11 or there is a card problem, prompting you to check the card compartment, eliminate the fault, and put in the cards.

[0063] If there are cards in the card dealing channel when dealing (after the previous card is dealt, a portion of the next card may be brought out, resulting in blocking of the photoelectric signal sensor 65; this embodiment uses a downward pressure baffle with elastic downward pressure, so this kind of phenomenon is very rare), the card flying motor 21 and the card rolling motor 24 are reversed until the photoelectric signal sensor 65 is turned on (that is, the brought out portion returns to the card bin 11), and then the card flying motor 21 and the card rolling motor 24 stop rotating; then steps S1, S2, S3, S4, and S5 are executed.

[0064] Example 2

[0065] like Figure 13 and 14 As shown, the difference between this embodiment and embodiment 1 is that it further includes a cover plate 7 rotatably arranged at the front end of the card bin 11. The cover plate 7 replaces the installation side plate of embodiment 1. The downward pressure baffle 7 and other related structures (elastic downward pressure mechanism) are also arranged on the cover plate 7.

[0066] The above description is only a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformation made by using the contents of the description and drawings of the present invention, directly or indirectly applied in other related technical fields, is also included in the scope of protection of the present invention.
