[0016] Through the technical scheme, the cooperation of the insertion block and the insertion groove realizes quick disassembly and assembly of the poker placement box, the position layout of the card dispensing roller and the placement box ensures that the cards can be guided out one by one, avoids stagnation, and provides stable card supply for subsequent card counting and transmission.

[0017] Preferably, a side groove corresponding to the playing cards is provided at the bottom side of the playing card storage box, a first conveyor belt is provided at the front side of the card dispensing roller, a pressure roller is provided above the first conveyor belt, and adjustment grooves are provided on the left and right sides of the pressure roller.

[0018] Through the above technical solution, the bottom side groove of the placement box is precisely adapted to the card size, ensuring that the card is exported one by one. The first conveyor belt realizes the transfer of the card to the counting area. The pressure roller can be flexibly adjusted in height through the adjustment groove to adapt to cards of different thicknesses and improve the versatility of the equipment.

[0019] Preferably, a middle cavity is provided at the front side of the first conveyor belt, a second conveyor belt is provided at the bottom of the middle cavity, a third conveyor belt is provided at the upper diagonal position of the second conveyor belt, and the bottom of the third conveyor belt is a card-separating conveyor belt.

[0020] Through the above technical solutions, the conveyor belt forms a continuous turning and transmission path, the intermediate cavity provides reasonable space for the layout of the conveyor belt, and the connection design between the third conveyor belt and the card-distributing conveyor belt ensures that the cards are smoothly introduced from the card-distributing mechanism into the card-shuffling mechanism.

[0021] Preferably, the playing cards are evenly fed into the two shuffling chambers via a card-distributing conveyor belt, and a transparent protective cover is provided on the outer side of the middle chamber.

The control buttons centrally control the start and stop of the equipment and the switching of functions. The electrical connection between the motor and the buttons ensures timely response to commands. The operation is simple and intuitive, reducing the threshold for use.

[0025] Compared with the prior art, the present invention provides a card shuffling integrated machine, which has the following beneficial effects: The design incorporates a shuffling chamber, a shuffling conveyor belt, a card outlet, a shuffling cavity, a card-splitting conveyor belt, a secondary card-splitting conveyor belt, a card-splitting outlet, a placement plate, a chute, a slide rail, a slider, a transmission belt, a transmission motor, and a rotating shaft. This configuration enhances the uniformity and flexibility of the shuffling process. The card-splitting conveyor belt receives cards from the third conveyor belt and distributes them evenly to both sides of the shuffling chamber, preventing accumulation on one side. After the shuffling conveyor belt efficiently agitates and shuffles the cards, they are sent through the card outlet to the placement plate in the shuffling chamber. The secondary card-splitting conveyor belt is located below the card-splitting conveyor belt, forming an upper and lower transmission structure. When it is necessary to improve the uniformity of the shuffling, the cards on the placement plate can be returned to the shuffling cavity for reshuffling to meet the high uniformity requirements. The transmission motor drives the transmission belt to move the slider along the slide rail, enabling the height adjustment of the placement plate. This allows for docking with the secondary card-splitting conveyor belt during secondary shuffling and also adjusts the card-retrieving height according to the card stacking amount. The chute provides auxiliary guidance to ensure smooth lifting and lowering.

[0026] By integrating a card-dispensing mechanism, card-dispensing rollers, a playing card storage box, plug-in blocks, slots, a first conveyor belt, pressure rollers, an adjustment groove, an intermediate cavity, a second conveyor belt, a third conveyor belt, a transparent protective cover, and card slots, the system achieves stable card transmission and card-dispensing functionality. The playing card storage box can be quickly assembled and disassembled via plug-in blocks and slots, facilitating card replenishment. The pressure rollers can be adjusted in height along the adjustment grooves to accommodate cards of different thicknesses, preventing transmission jams. The second and third conveyor belts form a turning channel to ensure smooth card entry into the shuffling mechanism. The transparent protective cover, installed via card slots, facilitates observation of the transmission status and protects internal components from dust, enhancing the equipment's practicality.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In this embodiment, the specific implementation steps of a card counting and shuffling integrated machine are as follows: The main body 1 of the integrated machine is placed on a flat table via the base 7. It is confirmed that the main body 1 of the integrated machine is placed stably and the base 7 is in contact with the table without shaking. The surfaces of each conveyor belt (first conveyor belt 14, shuffling conveyor belt 17, etc.) are checked to ensure that there are no debris or card residues and that the counting wheel 13 rotates flexibly without jamming. The transparent protective cover 28 is checked to ensure that it is undamaged and that the control button 4 and the counting display screen 5 respond normally after being powered on. It is ensured that the motor wiring is secure and not loose. The plug block 29 of the playing card placement box 6 is aligned with the slot 9 of the card counting mechanism 2 and inserted and fixed. The transparent protective cover 28 is opened, the playing cards to be processed are placed into the placement box 6, and the protective cover 28 is closed. Press the "Power On" button on control button 4. The counting display screen 5 lights up and displays "0", completing the device initialization. Align the plug block 29 at the bottom of the playing card placement box 6 with the slot 9 at the top of the card counting mechanism 2, and insert it vertically downwards until the buckle locks in place, achieving quick fixation of the placement box. Open the transparent protective cover 28 (simply pull it outwards along the card slot 8), place the arranged playing cards face down into the placement box 6, ensuring that the bottom of the cards fits against the bottom side groove of the placement box 6. Close the transparent protective cover 28 and confirm that it is fully engaged with the card slot 8. The motor drives the card dispensing roller 10 to rotate, dispensing the cards in the placement box 6 one by one through the bottom side groove to the first conveyor belt 14. The first conveyor belt 14 moves the cards forward, the pressure roller 11 presses the guide, and the counting roller 13 counts the number of cards in real time and displays it on the counting display screen 5 for easy verification of the number of cards. The transparent protective cover on the outside of the middle cavity 22... The protective cover 28 can be opened at any time to facilitate observation of the card transmission status. If card jamming occurs, the machine can be stopped immediately and the cards can be cleaned through the intermediate cavity 22 without disassembling the equipment casing. The cards enter the intermediate cavity 22 via the first conveyor belt 14, are then transferred to the third conveyor belt 23 via the second conveyor belt 15, and after being turned by the third conveyor belt 23, are sent to the card distribution conveyor belt 21 at the top of the card shuffling cavity 30. The card distribution conveyor belt 21 evenly distributes the cards to the two side shuffling cavities 16. The card shuffling conveyor belt 17 rotates to agitate and shuffle the cards. After shuffling, the cards fall through the card outlet 33 onto the placement plate 18 of the card shuffling cavity 30. To improve the uniformity of shuffling, start the drive motor 26 via control button 4. This will cause the drive belt 24 and slider 19 to slide along the slide rail 25, moving the placement plate 18 upwards to the bottom of the secondary card-splitting conveyor belt 31. Start the secondary card-splitting conveyor belt 31 to transfer the cards on the placement plate 18 to the card-splitting port 32, and then return them to the two side shuffling chambers 16 for a second shuffling. After shuffling is complete, adjust the drive motor 26 via control button 4 to cause the drive belt 24 and slider 19 to slide along the slide rail 25, raising the placement plate 18 to a suitable height. Hold the hand-held block 38 of the card-picking plate 37 and move it along... The guide strip 36 and the groove 39 take out the card taking plate 37 and cards. If the entertainment scene requires a high degree of uniformity in shuffling (such as competitive card games), the secondary shuffling function can be activated: by pressing the "secondary shuffling" button on the control button 4, the drive motor 26 starts and drives the drive belt 24 to rotate clockwise. The slider 19, which is fixedly connected to the drive belt 24, slides upward along the slide rail 25. At the same time, the placement plate 18 rises synchronously along the slide groove 20 under the drive of the slider 19 until the top of the placement plate 18 is in contact with the bottom of the secondary card dispensing conveyor belt 31 (the counting display screen 5 will display "secondary shuffling ready").

[0038] The secondary card-sorting conveyor belt 31 is activated, and its surface card-dispensing plates dispense the cards on the placement plate 18 one by one to the card-sorting slots 32 on the left and right sides. The cards then fall back into the shuffling chambers 16 on both sides through the card-sorting slots 32, and the above shuffling process is repeated. After the secondary shuffling is completed, the drive motor 26 rotates in the opposite direction, driving the placement plate 18 to the initial position, waiting to retrieve the cards.

[0039] After use, press the "Power Off" button to turn off the equipment power and unplug the power cord. Open the transparent protective cover 28 and the playing card storage box 6. Wipe the surface of each conveyor belt, the counting wheel 13, and the inside of the storage box with a dry, soft cloth to remove any remaining paper scraps and stains from the cards. Check areas prone to jamming, such as the card dispensing port 33 and the card separating port 32, to ensure there are no obstructions. Align the card picking plate 37 with the insert strip 36 and reset it. Close the transparent protective cover 28 and store the equipment in a dry, ventilated place.

[0040] The seamless connection of the first to third conveyor belts enables fully automated card flow from counting to shuffling, eliminating the need for manual card transfer and improving entertainment efficiency. The real-time linkage between the counting wheel 13 and the counting display screen 5 ensures accurate card counts and avoids errors caused by manual counting.

[0041] like Figures 1-8 As shown, a shuffling conveyor belt 17 is provided at the bottom of the shuffling chamber 16, a card outlet 33 is provided at the bottom inner side of the shuffling chamber 16, a shuffling chamber 30 is provided in the middle of the two shuffling chambers 16, a placement plate 18 is provided in the middle of the inside of the shuffling chamber 30, a chute 20 is provided at the rear of the shuffling chamber 30, a slide rail 25 is provided at the rear of the chute 20, a slider 19 is slidably connected inside the slide rail 25, the slider 19 is fixedly connected to the placement plate 18, a transmission belt 24 is fixedly connected at the rear of the slider 19, a transmission motor 26 is provided at the top of the transmission belt 24, a rotating shaft 27 is provided at the bottom of the transmission belt 24, the rotating shaft 27 is rotatably connected to the main body 1 of the integrated machine, a secondary card-splitting conveyor belt 31 is provided at the top of the shuffling chamber 30, and card-splitting outlets 32 are provided on the left and right sides of the secondary card-splitting conveyor belt 31, so that playing cards can re-enter the two shuffling chambers 16 through the secondary card-splitting conveyor belt 31.

[0042] The lifting mechanism, consisting of the drive motor 26, the drive belt 24, and the slide rail 25, works in conjunction with the secondary card-sorting conveyor belt 31 to form a closed-loop process of "shuffling-lifting-returning". The number of shuffling times can be flexibly selected according to needs, solving the problem of uneven shuffling in traditional equipment.

[0043] Preferably, the card-splitting conveyor belt 21 is positioned at the top of the shuffling chamber 30 and precisely connects with the third conveyor belt 23, ensuring smooth card input from the card-counting mechanism. It evenly distributes the cards to both sides of the shuffling chambers 16, and, in conjunction with the bidirectional stirring of the shuffling conveyor belt 17, efficiently disperses the cards, preventing uneven shuffling caused by one-sided accumulation. The inclined design of the card outlet 33 ensures that the shuffled cards fall smoothly onto the placement plate 18 of the shuffling chamber 30. The secondary card-splitting conveyor belt 31 is located directly below the card-splitting conveyor belt 21, forming a reasonable vertical layout that saves internal space while shortening the card return path. When improving the uniformity of shuffling, the drive motor 26 can drive the placement plate 18 to move upward along the slide rail 25 and the slide groove 20 to the bottom of the secondary card sorting conveyor belt 31, so that the cards are accurately connected to the transmission components. Through the cooperation of the secondary card sorting conveyor belt 31 and the card sorting port 32, the cards are sent back to the shuffling chamber 16 for reshuffling, forming a closed-loop process of "shuffling-lifting-returning", which significantly improves the uniformity of shuffling. The height adjustment function of the placement plate 18 can not only meet the needs of secondary shuffling, but also be flexibly adjusted according to the amount of cards stacked. The slide groove 20 plays a guiding and limiting role in the lifting and lowering of the placement plate 18, preventing deviation and ensuring stable operation.

[0044] like Figures 1-5 As shown, a card-dispensing roller 10 is located at the rear center of the top of the card-dispensing mechanism 2. A playing card storage box 6 is located above the card-dispensing roller 10. A plug-in block 29 is located at the bottom of the playing card storage box 6. A slot 9 corresponding to the plug-in block 29 is located at the top of the card-dispensing mechanism 2. A side groove corresponding to the playing card is opened on the bottom side of the playing card storage box 6. A first conveyor belt 14 is located in front of the card-dispensing roller 10. A pressure roller 11 is located above the first conveyor belt 14. Adjustment grooves 12 are opened on the left and right sides of the pressure roller 11. A middle cavity 22 is located in front of the first conveyor belt 14. A second conveyor belt 15 is located at the bottom of the middle cavity 22. A third conveyor belt 23 is located diagonally above the second conveyor belt 15. A transparent protective cover 28 is located on the outside of the middle cavity 22. A slot 8 corresponding to the transparent protective cover 28 is opened inside the card-dispensing mechanism 2.

[0045] The plug-in design of the playing card holder 6 facilitates quick card replenishment, the interlocking structure of the card retrieval plate 37 ensures smooth card retrieval, the transparent protective cover 28 is easy to observe and dustproof, and the partitioned design of the control buttons 4 (card counting, shuffling, card retrieval) reduces the difficulty of operation and is suitable for users of different ages.

[0046] Preferably, the cooperation between the plug-in block 29 and the slot 9 enables quick assembly and disassembly of the playing card placement box 6, facilitating card replenishment and cleaning. The bottom side groove of the placement box 6 precisely adapts to the card size, ensuring that the cards are exported one by one and avoiding jamming. The pressure roller 11 can be flexibly adjusted in height through the adjustment groove 12 to adapt to different specifications of playing cards, such as ordinary playing cards and thickened playing cards, improving the versatility of the equipment. The linkage design of the first, second and third conveyor belts forms a smooth transmission path, reducing card wear. The transparent protective cover 28 is conveniently installed through the card slot 8, which can not only observe the card transmission status in real time, but also prevent dust from entering the intermediate cavity 22, protecting the internal transmission components and extending the service life of the equipment.

[0047] like Figures 1-7 As shown, a control button 4 is located on the top left side of the card counting mechanism 2, a counting display screen 5 is located on the top right side of the card counting mechanism 2, a counting wheel 13 is located above the middle of the first conveyor belt 14, the counting display screen 5 is connected to the counting wheel 13, a motor is located on the left side of the roller and the conveyor belt, and the motor is electrically connected to the control button 4 through a wire.

[0048] The core separating component of the card-dispensing mechanism is a pair of symmetrically distributed card-dispensing rollers 10, which employ a "friction separation + gap limiting" design to achieve the separation of cards one by one. The distance between the two sets of rollers can be precisely adjusted within the range of 0.8-1.5cm via an adjusting screw. For standard playing cards (thickness approximately 0.3cm) or mini playing cards (thickness approximately 0.2cm), a suitable gap can be set—allowing only a single card to pass through, avoiding the stacking of multiple cards for dispensing.

[0049] The surface of the card-dispensing roller is covered with a nitrile rubber anti-slip layer, with a friction coefficient ≥0.6, which is much higher than the friction coefficient of the card surface (approximately 0.2). When the bottom of the card in the placement box 6 contacts the roller, the friction generated by the rotation of the roller drives the bottom single card outward. At the same time, the adjustable baffles on both sides inside the placement box are fixed by spring buckles, forming a lateral limit on the card stacking, preventing the cards from tilting and causing multiple cards to be dispensed simultaneously, ensuring that the separated cards enter the transmission stage in an "orderly single" state.

[0050] After separation, the cards need to reach the counting area via a stable transmission path. This is achieved through the coordinated action of the first conveyor belt 14 and the double pressure rollers 11. The width of the first conveyor belt is set to 6cm, slightly wider than the standard playing card width (5.7cm), ensuring no deviation during card transmission. The surface of the conveyor belt is provided with 0.3cm deep anti-slip texture to enhance friction with the bottom of the cards. The transmission speed can be adjusted from 1 to 3 cards / second via a control button, forming a synchronized linkage with the separation speed of the card-dispensing rollers (error ≤0.1m / s) to prevent cards from piling up or having excessively large gaps during transmission.

[0051] The dual pressure rollers 11 above the first conveyor belt adopt a "spring return + height adjustable" structure. The left and right sides of the pressure rollers are embedded in adjustment grooves 12 marked with scales (0.8-1.5cm). The springs provide continuous downward pressure (the pressure can be adjusted within the range of 0.5-1N), ensuring that the pressure rollers always keep in contact with the card surface. When encountering cards with slightly different thicknesses (such as a mixture of new and old playing cards), the pressure rollers can automatically rise and fall along the adjustment grooves to adapt to changes in card thickness. This ensures that the cards are pressed tightly and transported without slipping, while also preventing excessive pressure from causing the cards to bend or wear, providing a stable posture guarantee for subsequent accurate counting.

[0052] The counting process utilizes a high-precision photoelectric counting wheel 13, whose core components are an infrared beam sensor and an encoding wheel. This wheel is mounted above the center of the first conveyor belt, at a distance of 0.1-0.2 cm from the belt surface to ensure accurate triggering of the sensor signal when a card passes through. The encoding wheel has 360 evenly distributed light-transmitting holes on its surface. When a card passes beneath the counting wheel, it blocks the infrared beam, causing the encoding wheel to rotate synchronously with the card. Each rotation of a light-transmitting hole corresponds to the output of a pulse signal.

[0053] The infrared beam sensor has a recognition accuracy of ≤0.1mm, effectively distinguishing between cards (thickness ≥0.2cm) and foreign objects (such as paper scraps or dust, thickness <0.1cm). When a foreign object passes through, the light blocking time received by the sensor is shorter than the threshold (0.05 seconds), and the system determines it as an invalid signal and filters it. When a card passes through, the blocking time is stable at 0.1-0.3 seconds (matching the transmission speed), and the system determines it as a valid signal and counts it. This dual judgment mechanism of "thickness recognition + time threshold" keeps the counting error below 0.1%.

[0054] The pulse signal output by the counting wheel is transmitted to the central control module (STM32F103 chip). The counting detection unit in the module processes the pulse signal in real time: for each valid pulse signal received, the count value is incremented by 1 and synchronized to the 4.3-inch LCD touch screen through the data transmission link, realizing a millisecond-level response (delay ≤10ms) of "card passing - count accumulation - screen display", and the user can observe the card counting progress in real time.

[0055] Meanwhile, the data processing unit has a built-in anomaly detection algorithm. When the time interval between three consecutive cards passing through exceeds the threshold (e.g., when the transmission speed is 2 cards / second, the interval is >0.8 seconds) or there is no pulse signal input for a continuous period of time (>2 seconds), the system determines that the counting is abnormal and immediately triggers the fault diagnosis mechanism. The LCD screen displays the fault code "E02", the buzzer sounds an alarm, and the card counting process is paused to avoid counting deviations caused by card jamming or sensor failure, thereby improving the reliability of the card counting technology.

[0056] Optionally, control button 4 centrally controls the start / stop and function switching of the equipment, making operation simple and intuitive, requiring no complicated training. Counting wheel 13 counts the number of playing cards during transmission in real time, and the data is synchronously displayed on the counting display screen 5, ensuring accurate counting and avoiding errors from manual counting. This meets the needs of card count verification during entertainment. The electrical connection between the motor and control button 4 ensures timely command response and stable transmission, improving the ease of operation and user experience. The counting display screen 5 uses a clear and visible display method, making it easy for users to view from a distance and enhancing the practicality of the equipment.

[0057] like Figures 1-8 As shown, a base plate 34 is provided at the bottom of the placement plate 18, a slot 35 is provided at the front of the base plate 34, an array of insert strips 36 is provided at the top of the base plate 34, a card-retrieving plate 37 is provided above the placement plate 18, a hand-held block 38 corresponding to the slot 35 is provided at the bottom front of the card-retrieving plate 37, and a groove 39 corresponding to the insert strips 36 is provided at the bottom of the card-retrieving plate 37.

[0058] Optionally, the cooperation between the insert strip 36 and the groove 39 enables precise positioning of the card-retrieving plate 37 and the base plate 34, preventing the card-retrieving plate 37 from shifting and causing the cards to scatter. The hand-held block 38 makes it easy to hold and retrieve cards, and its locking design with the slot 35 makes the card-retrieving plate 37 more stable when placed, preventing the equipment from shifting due to vibration during operation and improving the convenience of retrieving cards.
