Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of entertainment tools, specifically relates to a shuffling mechanism of shuffling even. BACKGROUND

[0002] Paper cards are a kind of game and entertainment tools that people like, and there are many kinds, the most common ones are poker cards and card type mahjong cards, and various paper card games have different game rules. Traditional paper card games usually adopt manual shuffling and manual dealing, and it needs to spend more time and certain skills to shuffle the paper cards thoroughly and evenly and deal the paper cards accurately, and there is also the possibility of cheating, so it is difficult to ensure the fairness of the game, therefore, people have invented paper card automatic shuffling and dealing machines.

[0003] The existing shuffling machine is usually provided with two groups of shuffling mechanisms in opposite directions, the paper cards are staggered and dropped into the card warehouse through the two groups of shuffling mechanisms, so that shuffling is realized. However, the two groups of shuffling mechanisms are driven separately by two groups of power mechanisms, so that the two groups of shuffling mechanisms cannot be accurately synchronized, the shuffling speed of the two sides is inconsistent, and the phenomenon that one side may have continuously shuffled multiple paper cards and the other side may have only shuffled one paper card occurs, resulting in uneven shuffling. SUMMARY

[0004] The utility model aims at the above-mentioned problems and deficiencies, and provides a shuffling mechanism with consistent shuffling speed on both sides, which ensures even shuffling.

[0005] The technical scheme of the utility model is realized as follows:

[0006] The shuffling mechanism for even shuffling has the following characteristics: the shuffling mechanism is provided with two groups in opposite directions, and the two groups of shuffling mechanisms are driven to rotate synchronously by the same power mechanism.

[0007] In order to make the setting of the power mechanism simple and the driving effect good, the power mechanism comprises a motor and two groups of transmission gears connected with the power output gear of the motor, and the two groups of transmission gears are connected with one group of shuffling mechanisms respectively.

[0008] In order to make the paper cards be smoothly conveyed and not appear the problem of sticking and stacking, each group of the shuffling mechanisms has a fan-shaped wheel auxiliary mechanism for pushing the paper cards into the shuffling opening, the fan-shaped wheel auxiliary mechanism is located below the card receiving plate arranged at the shuffling mechanism, and the fan-shaped wheel on the fan-shaped wheel auxiliary mechanism protrudes upward from the upper side of the card receiving plate by a certain height intermittently in the rotating process to realize the pushing of the paper cards.

[0009] To ensure smooth card transfer, each set of 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 of the shuffling mechanism and are coaxially connected to the shuffling conveyor wheel. The remaining fan-shaped wheel is located outside the shuffling conveyor wheel and is linked to it.

[0010] In order to ensure that the playing cards can be smoothly fed into the shuffling port, the two sector wheels that are coaxially connected to the shuffling conveyor wheel are set as small sector wheels, and the sector wheel located outside the shuffling conveyor wheel is set as a large sector wheel.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] This invention employs a structure where two shuffling mechanisms are driven by the same power mechanism, enabling precise synchronous rotation of the two mechanisms. This ensures consistent rotation speeds on both sides, preventing situations where one side may have shuffled multiple cards consecutively while the other has only shuffled one. This effectively improves the uniformity of the shuffling process and results in a better shuffling effect. Furthermore, the synchronous rotation of the two shuffling mechanisms, combined with the auxiliary mechanism of the sector gear, keeps the cards in a loose state throughout the shuffling process, preventing them from sticking together and causing stacking issues during transport. This results in a more even and thorough shuffling.

[0013] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0018] The uniform shuffling mechanism described in this utility model can be applied to existing shuffling machines, existing integrated shuffling and card-dispensing machines, and other applications such as... Figures 2-4 On the shampoo and shampoo combo machine shown. At this time, as Figures 1-4As shown, the hair-washing card machine comprises a base 1 and a hair-washing card device 2 rotatably connected to the top of the base 1 through a rotating mechanism 3. The hair-washing card device 2 comprises a shell 20, a card accommodating bin 21 arranged on the shell 20, two sets of card-shuffling mechanisms 22 arranged oppositely on the shell 20 and located at the upper part of the card accommodating bin 21 for pushing the interlaced cards into the card accommodating bin 21, a set of card-dealing mechanisms 23 arranged on the shell 20 and located at the bottom of the card accommodating bin 21 for sending the washed cards in the card accommodating bin 21, and a circuit controller 24 arranged on the shell 20 and electrically connected with the rotating mechanism 3, the card-shuffling mechanisms 22 and the card-dealing mechanisms 23. Since the upper part of the card accommodating bin 21 is communicated with a card-shuffling port 223 and the rear part is communicated with a card-dealing port 231, the card-shuffling mechanisms 22 and the card-dealing mechanisms 23 share one accommodating bin, so that the structure of the utility model is compact and reliable. Moreover, the front part of the card accommodating bin 21 has a card-taking port, so that the cards in the card accommodating bin 21 can be manually taken out through the card-taking port when not in use. In the embodiment, the shell 20 is composed of an upper shell 201, a middle shell 202 and a lower shell 203 fixed by buckles or screws. The panel 241 of the circuit controller 24 is arranged on the top of the upper shell 201, the circuit board of the circuit controller 24 is located at the bottom of the panel 241, and switches corresponding to the positions and number of the buttons on the panel 241 are arranged on the circuit board. The circuit controller 24 further comprises a storage battery 242 fixed on the lower shell 203 and connected with the charging circuit of the circuit controller 24. The charging interface 243 of the charging circuit is arranged on the lower shell 203 and located below the card-taking port of the card accommodating bin 21, and the circuit main switch 244 is arranged beside the charging interface 243. In order to facilitate operation and display, the panel 241 can be a panel with a display screen, so that the number of players and the setting of the card-dealing direction can be displayed, and the operation is more intuitive. In addition, a loudspeaker 9 electrically connected with the circuit controller 24 is arranged in the shell 20 to play a prompting role.

[0019] The card accommodating bin 21 is integrally formed by the middle shell 202, a support seat 14 capable of covering the top opening of the card accommodating bin 21 is installed on the top of the middle shell 202 by screws or buckles, a connecting seat 15 is arranged above the support seat 14, the connecting seat 15 is fixedly installed on the bottom of the upper shell 201 by screws or buckles, and two shuffling openings 223 are formed between the connecting seat 15 and the support seat 14 and are oppositely arranged, specifically, the two shuffling openings 223 are symmetrically arranged on the left and right sides of the card accommodating bin 21. A set of shuffling mechanisms 22 is installed at the positions of the support seat 14 corresponding to the shuffling openings 223, and a card receiving plate 222 is arranged on each set of shuffling mechanisms 22, each card receiving plate 222 is arranged from outside to inside and from top to bottom, that is, the outside is high and the inside is low, so that the cards placed on the card receiving plate 222 can stably slide towards the shuffling openings 223 and will not scatter outward. In the embodiment, each set of shuffling mechanisms 22 is composed of a shuffling conveying wheel 224 and a set of fan-shaped wheel auxiliary mechanisms 221, each set of fan-shaped wheel auxiliary mechanisms 221 is provided with three fan-shaped wheels, and the three fan-shaped wheels are arranged in a triangular shape, and the shuffling conveying wheel 224 and the three fan-shaped wheels on each set of shuffling mechanisms 22 are synchronously rotated by means of linkage gears and rotating shafts. Moreover, two of the fan-shaped wheels are small fan-shaped wheels 2211, and the remaining one is a large fan-shaped wheel 2212, that is, the radius of the small fan-shaped wheel 2211 is smaller than that of the large fan-shaped wheel 2212. The two small fan-shaped wheels 2211 are arranged near the positions of the shuffling openings 223 and are coaxially connected with the shuffling conveying wheel 224 through rotating shafts 225, and the large fan-shaped wheel 2212 is arranged on the outside of the shuffling conveying wheel 224 and is drivingly connected with the shuffling conveying wheel 224 through linkage gears 226. Of course, the two small fan-shaped wheels 2211 can also be drivingly connected with the shuffling conveying wheel 224 through gears, as long as the synchronous rotation of the two small fan-shaped wheels 2211, the shuffling conveying wheel 224 and the large fan-shaped wheel 2212 is ensured. Meanwhile, through holes are formed on each card receiving plate 222 at positions corresponding to the two small fan-shaped wheels 2211 and the large fan-shaped wheel 2212, the two small fan-shaped wheels 2211 and the large fan-shaped wheel 2212 are arranged in the through holes at the corresponding positions, and protrude upward from the upper side of the card receiving plate 222 by a certain height during rotation to push the cards into the shuffling openings 223. Since each set of shuffling mechanisms 22 adopts three fan-shaped wheels, when the fan-shaped wheels rotate, they will intermittently protrude upward from the upper side of the card receiving plate 222, so as to promote the up-and-down shaking of the cards and make the cards more loose, thereby ensuring that the cards will not be adsorbed and adhered to each other, preventing the card stack from being conveyed, and improving the shuffling accuracy.Since two of the three fan-shaped wheels are close to the position of the shuffling opening 223, in order to ensure that the cards can be smoothly sent into the shuffling opening 223 while being shaken, the two fan-shaped wheels close to the shuffling opening 223 are set as small fan-shaped wheels 2211, and the fan-shaped wheel located outside the shuffling opening 223 is set as a large fan-shaped wheel 2212. In this way, the shaking amplitude of the cards on the outside is larger, and the shaking amplitude of the cards on the inside is smaller, thereby avoiding the problem that the cards are not conducive to being sent due to excessive shaking at the shuffling opening 223. Moreover, the three fan-shaped wheels are arranged in a triangular shape, thereby achieving synchronous pushing of the cards from three positions, so that the transmission of the cards is stable. In addition, the large fan-shaped wheel 2212 can be set as a fan-shaped gear, and the friction between the large fan-shaped wheel 2212 and the cards is increased through the teeth thereon, so that the cards will not slip during pushing, and the shuffling effect is further improved.

[0020] The shuffling transmission wheel 224 is arranged at the middle position of the shuffling opening 223, and a rotating wheel type shuffling limiting mechanism 7 is arranged above the shuffling transmission wheel 224. Specifically, the rotating wheel type shuffling limiting mechanism 7 includes a mounting seat 71, a connecting shaft 72 arranged on the mounting seat 71, and a card limiting wheel 73 sleeved on the connecting shaft 72. The inner hole diameter of the card limiting wheel 73 is slightly larger than the outer diameter of the connecting shaft 72, so that the card limiting wheel 73 can rotate and move up and down on the connecting shaft 72. The mounting seat 71 is fixed on the connecting seat 15 by screws, and at this time, a slot 151 is formed at the position of the connecting seat 15 corresponding to the mounting seat 71, and the card limiting wheel 73 is rotatably arranged in the slot 151. Since the card limiting wheel 73 is arranged above the shuffling transmission wheel 224 and cooperates with the shuffling transmission wheel 224, a limiting gap is formed between the rotatable card limiting wheel 73 and the shuffling transmission wheel 224, thereby achieving the purpose of limiting the space of the cards during shuffling. The cards are always in full contact with the shuffling transmission wheel 224, and the phenomenon of sticking and slipping does not occur. At the same time, the purpose of limiting the number of cards during shuffling is achieved, and the shuffling of one card at a time is realized as much as possible, thereby avoiding the problem that the cards are stuck and added during shuffling, thereby effectively improving the shuffling smoothness, and each shuffling is more uniform and complete. Since the card limiting wheel 73 is arranged at the middle upper position of the shuffling opening 223, and a large enough space is left at both ends of the card limiting wheel 73, even if a curved card is encountered, the card can be smoothly and accurately transmitted into the shuffling opening 223, thereby avoiding the problem of jamming during shuffling. Moreover, since the card limiting wheel 73 can move up and down by a certain distance, the transmission of cards of different thicknesses can be realized through the card limiting wheel 73, thereby greatly improving the application range and better meeting the use requirements of players.

[0021] In the embodiment, the two sets of shuffling mechanisms 22 are driven by the same motor 227. Specifically, the two sets of shuffling mechanisms 22 are respectively connected with the power output gear of the motor 227 through a set of transmission gears 228. The motor 227 is fixedly installed on the connecting seat 15, each transmission gear 228 is rotatably connected in a box, and the box is installed on the supporting seat 14. Moreover, the two sets of shuffling mechanisms 22 are assembled in opposite angles in the rotation direction, so that the cards placed on the two card receiving plates 222 can be staggered and dropped into the card accommodating bin 21 when the motor 227 drives the two sets of shuffling mechanisms 22 to rotate synchronously, so as to complete the shuffling. Since the same motor 227 is used to drive the shuffling, the speed consistency of the two sides of the shuffling can be achieved, so that the shuffling is more uniform, and the shuffling effect is better.

[0022] In the embodiment, a card plate adjusting and limiting mechanism 5 can be arranged on the hair card shuffling device 2 and horizontally arranged at the outer side of the two sets of shuffling mechanisms 22. The card plate adjusting and limiting mechanism 5 can not only position the cards on the card receiving plate 222 to prevent the cards from falling from the side, but also adjust the use distance of the card receiving plate 222 in the length direction of the card, so as to be suitable for shuffling operation of cards of different lengths, such as regular cards and cards used internationally. In addition, an electric adjusting and limiting mechanism can also be arranged to adjust the space of the card length.

[0023] Specifically, the card plate adjusting and limiting mechanism 5 includes a positioning baffle 51, a fixed connecting rod 52 fixedly connected to the positioning baffle 51, and a limiting card plate 53 detachably connected to the fixed connecting rod 52. The fixed connecting rod 52 is provided in multiple, and the multiple fixed connecting rods 52 are evenly divided into two groups and arranged in left-right symmetry. In the embodiment, the fixed connecting rod 52 is provided in four, and each fixed connecting rod 52 is a square rod. The two fixed connecting rods 52 on the same side are arranged in up-down. The connecting holes for the fixed connecting rod 52 to pass and fix are arranged between the upper shell 201 and the connecting seat 15 and on the supporting seat 14. The limiting card plate 53 is provided with a card slot 531 opening downward. The number of the card slot 531 is the same as that of the fixed connecting rod 52, and the positions correspond, that is, one card slot 531 can be connected to one fixed connecting rod 52. When the limiting card plate 53 is connected to the fixed connecting rod 52 on the inner side of the positioning baffle 51, the cards with shorter length can be placed on the card receiving plate 222. When the limiting card plate 53 is removed, the cards with longer length can be placed on the card receiving plate 222. Meanwhile, limiting stoppers can also be arranged on the outer sides of the card receiving plates 222 away from the shuffling opening 223. The limiting card plate 53 can more quickly and conveniently and accurately adjust the length of the cards placed on the card receiving plate 222.

[0024] In addition, the card plate adjusting limiting mechanism 5 can also be replaced by a screw adjusting limiting mechanism. At this time, the screw adjusting limiting mechanism comprises a limiting baffle, an adjusting screw arranged on the limiting baffle and a plurality of sliding connecting rods. Connecting holes for the sliding connecting rods and the adjusting screw to pass through are arranged between the upper shell 201 and the connecting seat 15 and on the supporting seat 14. One end of each sliding connecting rod is fixed on the limiting baffle, and the other end is movably connected with the connecting hole. The adjusting screw is in threaded connection with the connecting hole. When the adjusting screw is twisted by the knob at the outer end of the adjusting screw, the limiting baffle can be moved inward or outward, so as to adjust the use distance of the card plate 222 in the length direction of the card. At this time, there are two control modes. One is that the adjusting screw is in threaded connection with the supporting seat arranged at the shuffling mechanism 22, so that the adjusting screw can move along the axial direction when it is twisted to drive the limiting baffle to move. The other is that the adjusting screw is in threaded connection with the limiting baffle, so that the limiting baffle moves along the axial direction of the adjusting screw by twisting the adjusting screw. Among them, the supporting seat is formed by the supporting seat 14 and the connecting seat 15. In addition, the plurality of sliding connecting rods are divided into two groups and symmetrically arranged on both sides of the adjusting screw. In this embodiment, a total of four sliding connecting rods are arranged, and each sliding connecting rod is a square rod. The two sliding connecting rods on the same side are arranged in an upper and lower manner. Of course, the sliding connecting rods can also be arranged in other numbers, and can be triangular, rhombic, etc. Since the movement of the limiting baffle is realized by the adjusting screw, not only the reliability of the connection is improved, but also even if the card shuffling device tilts to the side where the limiting baffle is located, the limiting baffle will not fall off, and the space for position adjustment is larger.

[0025] In the embodiment, the infrared indexing detection mechanism 4 is arranged between the base 1 and the card washing device 2. In this way, according to the number of players set by the players and the required card dispensing orientation, the card washing device 2 is detected at different orientations by the infrared indexing detection mechanism 4 during the rotation driven by the rotating mechanism 3, and when the detected orientation is the required card dispensing orientation, the card dispensing mechanism 23 is started to dispense cards. Specifically, the infrared indexing detection mechanism 4 comprises an infrared detection head 41 fixed at the bottom of the card washing device 2 and an indexing disc 42 fixed in the base 1, wherein the indexing disc 42 is ringed with a plurality of detection positions 422 at equal intervals, thereby dividing the indexing disc 42 into disc bodies with a plurality of detection positions at different angles. The infrared detection head 41 rotates around the indexing disc 42 driven by the card washing device 2 and cooperates with each detection position 422 on the indexing disc 42 to realize detection at different orientations, so as to identify the required card dispensing orientation. Since the infrared detection head 41 is slightly paused in the rotation direction when it rotates to the position of each detection position 422 according to the detection requirement, the angular rotation of the card washing device 2 can be realized through the cooperation of the infrared detection head 41 and each detection position 422. Since the card dispensing mechanism 23 determines whether to dispense cards according to the feedback of the detection signal of the infrared detection head 41, the infrared detection head 41 is connected with the circuit controller 24 through signals. In order to facilitate the setting of the indexing disc 42, the indexing disc 42 is composed of a disc 421 and a plurality of arc-shaped partitions coaxially and ringed on the disc 421 at equal intervals, each arc-shaped partition forms a detection position 422, and an empty position is formed between adjacent arc-shaped partitions, thereby achieving the purpose of angular detection through the empty position. Since the infrared detection head 41 is blocked by the arc-shaped partition at the detection position 422, the infrared rays emitted by the infrared detection head 41 are reflected to the receiving head, thereby identifying the angular orientation of the detection position 422. The disc 421 is installed and fixed in the base 1, each arc-shaped partition is integrally connected with the disc 421, and the infrared detection head 41 is fixed at the bottom of the lower shell 203 and straddles the arc-shaped partition. In the embodiment, eight arc-shaped partitions are ringed, that is, eight detection positions 422 are formed on the disc 421 through the eight arc-shaped partitions, thereby enabling the utility model to dispense cards to a maximum of eight players at the same time. Since eight detection positions 422 are ringed at equal intervals on the disc 421 at 360 degrees, the included angles of the center lines of the same positions of adjacent two detection positions 422 are 45 degrees, thereby completing the angular setting of the disc 421, that is, the card washing device 2 is rotated by 45 degrees when it rotates to the position of each detection position 422. In addition, the infrared indexing detection mechanism 4 can also be arranged in other structures, for example, a plurality of arc-shaped partitions can be directly fixed on the inner side of the base 1, and the infrared detection head 41 can be other detectors, as long as the required card dispensing orientation can be identified.Due to the infrared indexing detection mechanism 4 arranged in cooperation with the rotation of the card dispensing device 2, the infrared detection head 41 of the infrared indexing detection mechanism 4 can automatically detect a plurality of different angle detection positions 422, so as to determine whether the detected position is the position required for dispensing cards according to the setting requirement of the player, and the card dispensing device 2 will be slightly paused when detecting each position, and when it is determined that the detected position is the dispensing position required by the player, the card dispensing mechanism 23 is started to dispense cards to the position, and when the detected position is not the dispensing position required by the player, the card dispensing mechanism 23 will not be started, and the card dispensing device 2 is driven by the rotating mechanism 3 to rotate to the next detection position 422. In this way, the detection of each different position is realized, and whether the card dispensing is required is determined according to the recognition result, so that the cards can be accurately dispensed to the position of the player, and the problems of random dispensing and disorderly dispensing are avoided. Moreover, the dispensing position corresponds to the player one by one, and the card taking is convenient and fast, which greatly improves the convenience of use. The infrared detection head 41 can be the existing infrared detection head on the market, and the use of the circuit and the principle of infrared detection are easy to understand for those skilled in the art, so the specific description is not given here.

[0026] In the embodiment, the rotating mechanism 3 includes a fixed gear 31 fixed on the central shaft 11 of the base 1 and a motor gear driving mechanism 32 arranged on the card dispensing device 2. The power output gear 321 of the motor gear driving mechanism 32 is in meshing connection with the fixed gear 31, and the motor gear driving mechanism 32 drives the card dispensing device 2 to rotate through the power output gear 321 around the fixed gear 31. Specifically, the motor gear driving mechanism 32 is formed by a driving motor and a gear set in transmission connection with the power output shaft of the driving motor. In order to facilitate the arrangement of the central shaft 11, a through hole is formed in the disc 421 for the central shaft 11 to pass through, and the upper end of the central shaft 11 is arranged in the lower shell 203, and a bearing 33 for connecting with the lower shell 203 is fixed on the upper end of the central shaft 11, so that the lower shell 203 is rotatably connected to the central shaft 11 through the bearing 33. The motor gear driving mechanism 32 is installed on the lower shell 203, and the power output gear 321 is located at the bottom of the lower shell 203, so as to realize the meshing connection with the fixed gear 31 in the base 1. In addition, the rotating mechanism 3 can also adopt other structural forms, for example, a driving motor is vertically fixed in the base 1, and the power output shaft of the driving motor is directly connected with the lower shell 203, so as to drive the card dispensing device 2 to rotate through the driving motor. Through the cooperation of the rotating mechanism 3 and the infrared indexing detection mechanism 4, the cards can be accurately dispensed to the position of the player. In order to ensure the stability and reliability of the card dispensing device 2 during rotation, a plurality of counterweights can be arranged in the base 1.

[0027] In the embodiment, the card dispensing mechanism 23 is installed between the middle casing 202 and the lower casing 203, and comprises two sets of front and rear arranged card conveying wheels 232, a set of card dispensing wheels 233, and a motor gear mechanism 234 for driving the card conveying wheels 232 and the card dispensing wheels 233 to rotate synchronously. The motor gear mechanism 234 comprises a motor and a set of gear groups connected with the power output shaft of the motor, and the gear groups are connected with the card conveying wheels 232 and the card dispensing wheels 233. The card dispensing port 231 is formed on the middle casing 202, the card dispensing wheels 233 are close to the side where the card dispensing port 231 is located, and a card conveying port 235 is arranged on the inner side of the card dispensing port 231 and connected with the card dispensing port 231. A roller 236 is arranged above the card conveying port 235 corresponding to the position of the card dispensing wheels 233, and the roller 236 cooperates with the card dispensing wheels 233 to send the cards from the card dispensing port 231. The two sets of card conveying wheels 232 are arranged in parallel on the same horizontal plane and located at the position of the card accommodating compartment 21. At this time, a groove is formed on the bottom surface of the card accommodating compartment 21 for placing the card conveying wheels 232, and the card conveying wheels 232 protrude into the card accommodating compartment 21, so that the cards in the card accommodating compartment 21 can be conveyed to the card dispensing port 231, and the card dispensing is realized through the cooperation of the synchronously rotating card dispensing wheels 233 and the roller 236.
