Description

Technical Field

[0001] This utility model relates to the field of entertainment tools technology, specifically to a shuffling restriction mechanism that can improve the smoothness of shuffling. Background Technology

[0002] Playing cards are a popular form of entertainment, with many varieties, the most common being poker cards and mahjong sets. Each type of card game has its own set of rules. Traditional card games typically involve manual shuffling and dealing. Thoroughly shuffling and accurately dealing the cards requires considerable time and skill, and also presents the possibility of cheating, making it difficult to guarantee fairness. Therefore, automatic card shuffling and dealing machines were invented.

[0003] Existing card shuffling machines typically feed cards directly into the shuffling slot via a shuffling conveyor wheel. Because the cards are freely placed on the wheel, sufficient contact between the cards and the conveyor wheel cannot be guaranteed during transport, leading to sticking and slippage. Furthermore, the lack of space restriction for the cards during transport can cause them to stick and overlap, especially when the cards are bent, which can cause them to jam and fail to enter the shuffling slot. Therefore, existing card shuffling machines suffer from poor card transport smoothness and uneven shuffling. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems and deficiencies by providing a shuffling restriction mechanism that can effectively improve the smoothness of shuffling and make the shuffling more uniform and thorough.

[0005] The technical solution of this utility model is implemented as follows:

[0006] The shuffling restriction mechanism described in this utility model, which can improve the smoothness of shuffling, is characterized by: including a rotary shuffling restriction mechanism disposed above the shuffling conveyor wheel of the shuffling mechanism, and the rotary shuffling restriction mechanism and the shuffling conveyor wheel forming a gap that restricts the passage of cards.

[0007] To make the structure of this utility model simple and easy to set up, the rotary shuffling restriction mechanism includes a mounting base, a connecting shaft and a card limiting wheel, wherein the card limiting wheel is rotatably connected to the mounting base through the connecting shaft.

[0008] To facilitate free adjustment of the gap between the card limiting wheel and the shuffling conveyor wheel, the inner diameter of the card limiting wheel is slightly larger than the outer diameter of the connecting shaft.

[0009] To facilitate the installation of the license plate limiting wheel, the license plate limiting wheel is located in a slot opened in the middle of the shuffling port.

[0010] To ensure smooth card transfer and prevent cards from sticking together, a fan-shaped wheel auxiliary mechanism is provided below the rotary shuffling limiting mechanism.

[0011] To ensure smooth card transfer, the fan-shaped wheel auxiliary mechanism is equipped with three fan-shaped wheels arranged in a triangle. Two of the fan-shaped wheels are located near the shuffling port and are positioned on either side of the shuffling conveyor wheel and coaxially connected to it. The remaining fan-shaped wheel is located on the outside of the shuffling conveyor wheel and is linked to it.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] This invention employs a rotary shuffling limiting mechanism positioned above the shuffling conveyor wheel. The limiting gap between this mechanism and the conveyor wheel restricts the space for cards during shuffling, ensuring consistent contact between the cards and the conveyor wheel to prevent slippage and sticking. It also limits the number of cards passed through each time, shuffling one card at a time to avoid overlapping and stacking, thus significantly improving shuffling smoothness and ensuring a more even and thorough shuffling process. Furthermore, the limiting wheel of the rotary shuffling limiting mechanism is positioned above the center of the shuffling opening, with ample space at both ends. This allows even bent cards to be smoothly and accurately conveyed into the shuffling opening, preventing jamming. Additionally, the limiting wheel's vertical movement allows for the conveying of cards of varying thicknesses, greatly expanding its applicability and better meeting the needs of card players.

[0014] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0020] The shuffling restriction mechanism described in this utility model, which improves the smoothness of shuffling, can be applied to existing shuffling machines, existing integrated shuffling and dealing machines, and other applications such as... Figures 2-5 On the shampoo and shampoo combo machine shown. At this time, as Figure 1-Figure 5 As shown, the integrated card shuffling and dealing machine includes a base 1 and a card shuffling device 2 rotatably connected to the top of the base 1 via a rotating mechanism 3. The card shuffling and dealing device 2 includes a housing 20, a card holding compartment 21 mounted on the housing 20, two sets of shuffling mechanisms 22 facing each other on the housing 20 and located above the card holding compartment 21 for pushing cards into the card holding compartment 21 in an alternating manner, a set of dealing mechanisms 23 mounted on the housing 20 and located at the bottom of the card holding compartment 21 for distributing the shuffled cards from the card holding compartment 21, and a circuit controller 24 mounted on the housing 20 and electrically connected to the rotating mechanism 3, the shuffling mechanisms 22, and the dealing mechanisms 23. Because the upper part of the card holding compartment 21 is connected to the shuffling port 223 and the rear part is connected to the dealing port 231, by setting the shuffling mechanism 22 and the dealing mechanism 23 to share a single holding compartment, the structure of this utility model is compact and reliable. Furthermore, a card retrieval opening is provided at the front of the card storage compartment 21, allowing for convenient manual removal of the cards when not in use. In this embodiment, the housing 20 comprises an upper housing 201, a middle housing 202, and a lower housing 203, which are connected and fixed by snaps or screws. The panel 241 of the circuit controller 24 is mounted on the top of the upper housing 201, and the circuit board of the circuit controller 24 is located at the bottom of the panel 241, with switches corresponding to the positions and number of buttons on the panel 241. The circuit controller 24 also includes a battery 242, which is fixed to the lower housing 203 and connected to the charging circuit of the circuit controller 24. The charging interface 243 of the charging circuit is located on the lower housing 203 below the card retrieval opening of the card storage compartment 21, and a main circuit switch 244 is located next to the charging interface 243. For ease of operation and display, panel 241 can be configured as a panel with a display screen, which can show the player's settings for the number of players and the dealing position, making operation more intuitive. In addition, for the purpose of providing prompts, a speaker 9 electrically connected to the circuit controller 24 is also provided inside the housing 20.

[0021] The card holding compartment 21 is integrally formed by the intermediate shell 202. A support base 14, which covers the top opening of the card holding compartment 21, is installed on the top of the intermediate shell 202 by screws or clips. A connecting base 15 is provided above the support base 14, and this connecting base 15 is fixed to the bottom of the upper shell 201 by screws or clips. Two opposing shuffling ports 223 are formed between the connecting base 15 and the support base 14. Specifically, the two shuffling ports 223 are symmetrically arranged on the left and right sides of the card holding compartment 21. A set of shuffling mechanisms 22 is installed on the support base 14 at the positions corresponding to each shuffling port 223. Each set of shuffling mechanisms 22 is covered with a card receiving plate 222. Each card receiving plate 222 is inclined from the outside in and from top to bottom, i.e., the outer side is higher and the inner side is lower, so that the cards placed on the card receiving plate 222 can slide stably towards the shuffling port 223 without scattering outwards. In this embodiment, each shuffling mechanism 22 consists of a shuffling conveyor wheel 224 and a set of sector wheel auxiliary mechanisms 221. Each sector wheel auxiliary mechanism 221 has three sector wheels arranged in a triangular pattern. The shuffling conveyor wheel 224 and the three sector wheels on each shuffling mechanism 22 are synchronously rotated via a linkage gear and a rotating shaft. Two of the sector wheels are small sector wheels 2211, and the remaining sector wheel is a large sector wheel 2212, meaning the radius of the small sector wheel 2211 is smaller than the radius of the large sector wheel 2212. The two small sector wheels 2211 are located near the shuffling opening 223 and on the left and right sides of the shuffling conveyor wheel 224, coaxially connected to the shuffling conveyor wheel 224 via a rotating shaft 225. The large sector wheel 2212 is located on the outside of the shuffling conveyor wheel 224 and is connected to the shuffling conveyor wheel 224 via a linkage gear 226. Of course, the two small sector wheels 2211 can also be connected to the shuffling conveyor wheel 224 via gear transmission, as long as the two small sector wheels 2211, the shuffling conveyor wheel 224, and the large sector wheel 2212 rotate synchronously. Simultaneously, through holes are provided on each card-bearing plate 222 at positions corresponding to the two small sector wheels 2211 and the large sector wheel 2212. The two small sector wheels 2211 and the large sector wheel 2212 are placed in their respective through holes, and during rotation, they intermittently protrude upwards from the upper side of the card-bearing plate 222 to push the cards into the shuffling opening 223. Since each shuffling mechanism 22 uses three sector wheels, when each sector wheel rotates, it intermittently protrudes upwards from the upper side of the card-bearing plate 222, causing the cards to shake up and down, making the cards looser and ensuring that the cards do not stick together. This prevents cards from stacking during transport and improves the accuracy of shuffling.Since two of the three sector wheels are located near the shuffling opening 223, to ensure the cards are smoothly fed into the opening while vibrating, the two sector wheels near the opening 223 are designated as small sector wheels 2211, while the sector wheel located outside the opening 223 is designated as a large sector wheel 2212. This results in a larger vibration amplitude on the outer side and a smaller vibration amplitude on the inner side, thus avoiding the problem of excessive vibration at the opening 223 hindering card feeding. Furthermore, the three sector wheels are arranged in a triangle, achieving synchronous pushing of the cards from three points, thus ensuring smooth card feeding. Additionally, the large sector wheel 2212 can be configured as a sector gear, with its teeth increasing the friction between the large sector wheel 2212 and the cards, preventing slippage during card pushing and further improving the shuffling effect.

[0022] A shuffling conveyor wheel 224 is positioned at the center of the shuffling opening 223, and a rotary shuffling restriction mechanism 7 is positioned above the shuffling conveyor wheel 224. Specifically, the rotary shuffling restriction mechanism 7 includes a mounting base 71, a connecting shaft 72 mounted on the mounting base 71, and a limiting wheel 73 sleeved on the connecting shaft 72. The inner diameter of the limiting wheel 73 is slightly larger than the outer diameter of the connecting shaft 72, allowing the limiting wheel 73 to rotate and move up and down on the connecting shaft 72. The mounting base 71 is fixed to the connecting base 15 with screws. A slot 151 is provided on the connecting base 15 at the position corresponding to the mounting base 71, and the limiting wheel 73 is rotatably placed in the slot 151. Because a card-limiting wheel 73 is installed above the shuffling conveyor wheel 224 and works in conjunction with it, the limiting gap formed between the rotatable card-limiting wheel 73 and the shuffling conveyor wheel 224 achieves the purpose of limiting the space for cards to pass through during shuffling. This ensures that the cards are always in full contact with the shuffling conveyor wheel 224, preventing sticking and slippage. At the same time, it also limits the number of cards that pass through during shuffling, allowing for shuffling one card at a time as much as possible. This avoids the problem of cards sticking together and overlapping before entering the shuffling slot 223, thus effectively improving the smoothness of shuffling and making each shuffle more even and thorough. Furthermore, since the card-limiting wheel 73 is positioned above the center of the shuffling slot 223, with sufficient space at both ends, even bent cards can be smoothly and accurately conveyed into the shuffling slot 223, avoiding any jamming during the shuffling process. Furthermore, since the card-limiting wheel 73 can move up and down a certain distance, it can transmit cards of different thicknesses, greatly increasing its applicability and better meeting the needs of card players.

[0023] In this embodiment, the two sets of shuffling mechanisms 22 are driven by the same motor 227. Specifically, the two sets of shuffling mechanisms 22 are each connected to the power output gear of the motor 227 via a set of transmission gears 228. The motor 227 is mounted and fixed on the connecting seat 15, and each transmission gear 228 is rotatably connected to a housing, which is then mounted on the support seat 14. Furthermore, the two sets of shuffling mechanisms 22 are assembled at two opposite angles in the direction of rotation, so that when the motor 227 drives them to rotate synchronously, the cards placed on the two card-holding plates 222 can fall alternately into the card-holding compartment 21 to complete the shuffling. Because the shuffling is driven by the same motor 227, the shuffling speed on both sides is consistent, resulting in more uniform shuffling and a better shuffling effect.

[0024] In this embodiment, a card-shuffling device 2 may be equipped with a card-adjusting and limiting mechanism 5, which is horizontally positioned on the outer side of the two sets of card-shuffling mechanisms 22. The card-adjusting and limiting mechanism 5 can both position the cards on the card-receiving plate 222 to prevent them from scattering laterally, and adjust the working distance formed by the card-receiving plate 222 along the length of the cards, thus adapting to card-shuffling operations of different lengths, such as standard cards and internationally used cards. Alternatively, an electrically adjustable limiting mechanism can be provided to accommodate adjustments based on the length of the cards.

[0025] Specifically, the locking plate adjustment and limiting mechanism 5 includes a positioning baffle 51, a fixed connecting rod 52 fixedly connected to the positioning baffle 51, and a limiting locking plate 53 detachably connected to the fixed connecting rod 52. Multiple fixed connecting rods 52 are provided, and these rods are evenly divided into two groups and arranged symmetrically from left to right. In this embodiment, a total of four fixed connecting rods 52 are provided, each of which is a square rod. Two fixed connecting rods 52 located on the same side are arranged vertically. Connecting holes for the fixed connecting rods 52 to pass through and be fixed are provided between the upper housing 201 and the connecting seat 15, and on the support seat 14. The limiting locking plate 53 has downward-opening slots 531. The number of slots 531 is the same as the number of fixed connecting rods 52, and their positions correspond, meaning that one slot 531 can be engaged with one fixed connecting rod 52. When the limiting plate 53 is engaged with the fixed connecting rod 52 inside the positioning baffle 51, shorter playing cards can be placed on the card holder 222; when the limiting plate 53 is removed, longer playing cards can be placed on the card holder 222. Additionally, limiting blocks can be installed on the outer edges of each card holder 222 away from the shuffling opening 223. The limiting plate 53 allows for quicker and more accurate adjustment of the length of the playing cards placed on the card holder 222.

[0026] In addition, the card plate adjustment limiting mechanism 5 can also be replaced by a screw adjustment limiting mechanism. In this case, the screw adjustment limiting mechanism includes a limiting baffle, an adjusting screw and several sliding connecting rods set on the limiting baffle. Connecting holes for the sliding connecting rods and adjusting screws are respectively provided between the upper housing 201 and the connecting seat 15 and on the support seat 14. One end of each sliding connecting rod is fixed to the limiting baffle, and the other end is movably connected to the connecting hole. The adjusting screw is threadedly connected to the connecting hole. When the adjusting screw is turned by the knob at the outer end of the adjusting screw, the limiting baffle can be moved inward or outward, thereby achieving the purpose of adjusting the working distance of the card holder 222 in the length direction of the card. At this time, there are two control methods. One is that the adjusting screw is threadedly connected to the support seat set at the shuffling mechanism 22, so that the adjusting screw can move along its axial direction when rotated, thereby driving the limiting baffle to move. The other is that the adjusting screw is threadedly connected to the limiting baffle, so that the limiting baffle can move along the axial direction of the adjusting screw by rotating the adjusting screw. The support base is formed by the support base 14 and the connecting base 15. Furthermore, several sliding connecting rods are arranged symmetrically in two groups on both sides of the adjusting screw. In this embodiment, a total of four sliding connecting rods are provided, and each sliding connecting rod is a square rod, with two sliding connecting rods on the same side arranged vertically. Of course, the number of sliding connecting rods can also be other, and they can be triangular, rhomboid, etc. Since the movement of the limiting baffle is achieved by adjusting the screw, not only is the reliability of the connection improved, but even if the shampoo device tilts towards the side where the limiting baffle is located, the limiting baffle will not fall off, and the range of position adjustment is greater.

[0027] In this embodiment, an infrared division detection mechanism 4 is provided between the base 1 and the card-shuffling device 2. Thus, based on the number of players set by the player and the desired card-dealing direction, the card-shuffling device 2, while rotating driven by the rotating mechanism 3, detects cards at multiple different positions via the infrared division detection mechanism 4. When the detected position matches the desired card-dealing position, the card-dealing mechanism 23 is activated to deal the cards. Specifically, the infrared division detection mechanism 4 includes an infrared detection head 41 fixed to the bottom of the card-shuffling device 2 and a division plate 42 fixed within the base 1. The division plate 42 has several equally spaced detection positions 422, thus dividing it into a plate with multiple detection positions at different angles. The infrared detection head 41 rotates around the division plate 42 under the drive of the card-shuffling device 2 and works in conjunction with the detection positions 422 on the division plate 42 to detect different positions and identify the desired card-dealing direction. When the infrared detection head 41 rotates to the position of each detection position 422, the card-shuffling device 2 will pause slightly in the direction of rotation according to the detection needs. Therefore, the angular rotation of the card-shuffling device 2 can be achieved through the cooperation of the infrared detection head 41 and each detection position 422. Since the card-distributing mechanism 23 determines whether to perform the card-distributing operation based on the detection signal feedback from the infrared detection head 41, the infrared detection head 41 is connected to the circuit controller 24 via a signal. To facilitate the setting of the indexing plate 42, the indexing plate 42 consists of a disc 421 and several arc-shaped partitions coaxially and equally spaced around the disc 421. Each arc-shaped partition forms a detection position 422, and a gap is formed between two adjacent arc-shaped partitions, thereby achieving the purpose of angular detection through the gap. At the detection position 422, the infrared light emitted by the infrared detection head 41 is reflected to the receiving head due to the obstruction of the arc-shaped partitions, thus enabling the identification of the angular orientation of the detection position 422. The disc 421 is fixedly installed inside the base 1. Each arc-shaped partition is integrally connected to the disc 421. The infrared detection head 41 is fixed to the bottom of the lower housing 203 and spans across the arc-shaped partitions. In this embodiment, eight arc-shaped partitions are arranged in a ring, meaning that eight detection positions 422 are formed on the disc 421 through the eight arc-shaped partitions, thus allowing the present invention to deal cards to up to eight players simultaneously. Since the eight detection positions 422 are arranged in a ring at 360-degree intervals on the disc 421, the angle between the center lines of two adjacent detection positions 422 at the same position is 45 degrees, thus completing the angle division setting of the disc 421. That is, the card shuffling device 2 rotates 45 degrees each time it rotates to the position of a detection position 422. In addition, the infrared division detection mechanism 4 can also be configured with other structures. For example, several arc-shaped partitions can be directly fixed on the inner side of the base 1, and other detectors can be used for the infrared detection head 41, as long as they can identify the direction of the card to be dealt.Because an infrared indexing detection mechanism 4 is set up to cooperate with the rotation of the card shuffling device 2, the infrared detection head 41 of the infrared indexing detection mechanism 4 can automatically detect multiple detection positions 422 at different angles. This allows the device to identify whether the detected position is the position where cards need to be dealt according to the player's settings. When detecting each position, the card shuffling device 2 will pause slightly. When it is determined that the detected position is the position where cards need to be dealt, the card dealing mechanism 23 is activated to deal cards to that position. When the detected position is not the position where cards need to be dealt, the card dealing mechanism 23 will not be activated, and the card shuffling device 2 will be driven to the next detection position 422 by the rotation mechanism 3. This rotation detection not only realizes the detection of each different position, but also determines whether cards need to be dealt based on the recognition results. This ensures that the cards are accurately dealt to the player's position, preventing random or haphazard dealing. Moreover, the card dealing position corresponds one-to-one with the player, making card retrieval convenient and quick, greatly improving the ease of use. The infrared detection head 41 can be any existing infrared detection head on the market, and its combination with the circuit and the principle of infrared detection are easy for those skilled in the art to know and understand, so it will not be described in detail here.

[0028] In this embodiment, the rotating mechanism 3 includes a fixed gear 31 fixed on the central shaft 11 of the base 1 and a motor gear drive mechanism 32 disposed on the shampoo holder 2. The power output gear 321 of the motor gear drive mechanism 32 meshes with the fixed gear 31, and the motor gear drive mechanism 32 drives the shampoo holder 2 to rotate by the rotation of the power output gear 321 around the fixed gear 31. Specifically, the motor gear drive mechanism 32 is formed by a drive motor and a gear set that is driven by the power output shaft of the drive motor. In order to facilitate the setting of the central shaft 11, a through hole is provided on the disc 421 for the central shaft 11 to pass through, and the upper end of the central shaft 11 passes through the lower housing 203. A bearing 33 for connecting with the lower housing 203 is fixed at the upper end of the central shaft 11, and the lower housing 203 is rotatably connected to the central shaft 11 through the bearing 33. The motor gear drive mechanism 32 is mounted on the lower housing 203, and the power output gear 321 is located at the bottom of the lower housing 203, thereby achieving meshing connection with the fixed gear 31 inside the base 1. Alternatively, the rotating mechanism 3 can adopt other structural forms, such as a drive motor vertically fixed inside the base 1, with the drive motor's power output shaft directly connected to the lower housing 203, thereby driving the card-shuffling device 2 to rotate. By cooperating with the rotating mechanism 3 and the infrared indexing detection mechanism 4, the cards can be accurately distributed to the player's location. To ensure the stability and reliability of the card-shuffling device 2 during rotation, several evenly distributed counterweights can also be installed inside the base 1.

[0029] In this embodiment, the card dealing mechanism 23 is installed between the intermediate housing 202 and the lower housing 203, and includes two sets of card-passing wheels 232 arranged in a front-to-back pattern, a set of card-dealing wheels 233, and a motor gear mechanism 234 for driving the card-passing wheels 232 and card-dealing wheels 233 to rotate synchronously. The motor gear mechanism 234 includes a motor and a set of gears that are connected to the power output shaft of the motor. This gear set is connected to each set of card-passing wheels 232 and card-dealing wheels 233. The card-dealing opening 231 is located on the intermediate housing 202. The card-dealing wheel 233 is located near the card-dealing opening 231. A card-passing opening 235, communicating with the card-dealing opening 231, is provided inside the card-passing opening 231. A roller 236 is provided above the card-dealing wheel 233 within the card-passing opening 235. This roller 236 works in conjunction with the card-dealing wheel 233 to dispense the cards from the card-dealing opening 231. Two sets of card-passing wheels 232 are set parallel to each other on the same horizontal plane and are located at the card holding compartment 21. At this time, the bottom surface of the card holding compartment 21 is provided with slots for the card-passing wheels 232 to be placed. The card-passing wheels 232 protrude from the card holding compartment 21, so that the shuffled cards in the card holding compartment 21 can be conveyed to the dealing port 231. The cards are dealt through the cooperation of the synchronously rotating dealing wheel 233 and the roller 236.

[0030] This invention achieves card shuffling through two sets of shuffling mechanisms 22. When dealing cards after shuffling, the player first sets the number of players and the required dealing position on the circuit controller 24. Then, the rotating mechanism 3 is activated to drive the card shuffling and dealing device 2 to rotate. During the rotation, the card shuffling and dealing device 2 detects the detection positions 422 at different positions through the infrared detection head 41. When the detected position is the dealing instruction position set by the player, the card dealing mechanism 23 is activated to deal cards at that position. When the detected position is not the dealing instruction position set by the player, the card dealing mechanism 23 will not activate the dealing mechanism. At this time, the card shuffling and dealing device 2 will rotate to the next detection position 422 until all the required dealing positions are detected. For example: In this game, there are four players. Adjacent players are seated at 90-degree angles to each other, forming four different dealing positions. First, the number of players is set to four on the circuit controller 24. Since the angle between the center lines of two adjacent detection positions 422 is 45 degrees, it is necessary to set a dealing position every other detection position 422. In this way, the angle between the center lines of the two detection positions 422 separated by this detection position is 90 degrees, which is the same as the angle at which the players are seated. Thus, when the card shuffling and dealing device 2 is rotating, the infrared detection head 41 will only detect the dealing command set by the player in the four set positions. Therefore, the card dealing mechanism 23 will only deal cards in these four positions. Although this utility model has a total of eight detection positions, since the dealing command set by the player is not detected in other positions, no cards will be dealt in other positions. Of course, it can also be set to four consecutive card dealing positions. In this case, two adjacent players sit at a 45-degree angle to each other in different positions. In this way, when the card dealing device 2 is rotating, the infrared detection head 41 will only detect the card dealing command set by the player in the four consecutive detection positions 422, thereby starting the card dealing mechanism 23 to deal cards. Since the card dealing command set by the player is not detected in other positions, no cards will be dealt.

Other variations of the disclosed embodiments, which are readily apparent to those skilled in the art, should fall within the scope of the claims of this utility model, with reference to the description of this utility model.
