Description

Technical Field

[0001] The utility model relates to a poker dealing tool, in particular to a simple card dealer capable of achieving accurate card dealing. Background Art

[0002] Playing cards are a favorite form of entertainment for people. After playing a game of cards, players need to sort, shuffle, and deal the cards themselves. To save time in dealing the cards, people have invented automatic card dealers to deal the cards. By placing a set of playing cards into the automatic card dealer, the automatic card dealer can use a conveying device inside to send the playing cards out from the card outlet while rotating, thus automatically sending the playing cards in front of different players.

[0003] A patent document with the publication number CN201164714Y discloses a four - outlet poker card dealer, which has a shuffling chamber. A shuffling differential is installed in the center of the shuffling chamber and is driven by a shuffling motor. Four conveyor belts connected to the card - dealing mechanism are evenly distributed around it. The conveyor belts are driven by a conveying motor. A card - sorting wheel is installed on one side of each conveyor belt, and a stopper cooperating with the card - sorting wheel is installed on the other side. A spiral dial is installed on the card - sorting wheel, and a counting light eye is installed at the output end of the card - dealing mechanism. When using this card dealer, the disordered cards are placed face - down into the shuffling chamber and are sent out from four card outlets after passing through the shuffling differential, the card - sorting wheel, and the card - dealing mechanism. The utility model patent with the publication number CN219941748U discloses a card dealer capable of switching the number of players. The bottom of this card dealer is provided with a motor, an incomplete gear set, and a fork mechanism. Inside the rotating frame above it, there are an incomplete gear set, a fork mechanism, a first pulley, and a second pulley. When the number of players changes, the first pulley and the belt need to be replaced to ensure that the ratio of the diameter of the first pulley to the diameter of the second pulley is equal to the number of players.

[0004] Both of the above - mentioned card dealers can achieve automatic card dealing, but the structures of the above - mentioned two card dealers are relatively complex, and the accuracy of card dealing still needs to be improved. Summary of the Invention

[0005] In order to solve the problems of the complex structure and low card - dealing accuracy of the existing card dealers, the utility model provides a simple card dealer capable of achieving accurate card dealing.

[0006] The utility model is realized by adopting the following technical scheme: A simple card dealer capable of accurately dealing cards, comprising a housing. A first motor is arranged on the inner bottom plate of the housing. A first incomplete gear is connected to the output shaft of the first motor. A first complete gear is also arranged on the inner bottom plate of the housing through a vertical first rotating shaft. The first incomplete gear meshes with the first complete gear. The first rotating shaft is connected to a first sprocket. The first sprocket meshes with a first annular bearing. The middle shaft of the first annular bearing is fixed in a bearing arranged in the housing. The middle shaft of a second annular bearing is slidably connected to the middle shaft of the first annular bearing. The second annular bearing meshes with a second sprocket. The second sprocket is connected to a second rotating shaft in the housing. The top of the second rotating shaft extends out of the housing and is connected to a rotating frame. The second sprocket is a multi-layer sprocket. A second motor is arranged in the rotating frame. A second incomplete gear is connected to the output shaft of the second motor. The second incomplete gear meshes with a second complete gear. A card pushing roller is connected to the shaft of the second complete gear. A card box is fixed at the bottom inside the rotating frame. The card box is below the card pushing roller.

[0007] For this card dealer, the first motor drives the first incomplete gear to rotate. The first incomplete gear drives the first complete gear to rotate. The first complete gear drives the first sprocket to rotate. The first sprocket drives the first annular bearing and the second annular bearing to rotate. The second annular bearing then drives the second sprocket to rotate. When the second sprocket rotates, the rotating frame above rotates. The second motor in the rotating frame drives the second incomplete gear to rotate. The second incomplete gear drives the second complete gear in the rotating frame to rotate. The second complete gear drives the card pushing roller to pick out the cards in the card box below. Each layer of the second sprocket corresponds to the number of players for a certain type of poker game. When the number of players changes, the second annular bearing is toggled to make the second annular bearing mesh with a certain layer of the second sprocket.

[0008] For the above-mentioned simple card dealer capable of accurately dealing cards, the end of the middle shaft of the second annular bearing is of an external spline structure, and the end of the middle shaft of the first annular bearing is of an internal spline structure. The middle shaft of the second annular bearing is slidably connected to the middle shaft of the first annular bearing through splines.

[0009] A simple card dealer that can achieve precise card dealing, comprising a housing. A first motor is arranged on the inner bottom plate of the housing. A fourth complete gear is connected to the output shaft of the first motor. An incomplete gear set is also vertically arranged on the inner bottom plate of the housing. The incomplete gear set includes n incomplete gears and one complete gear. The n incomplete gears and the complete gear are sequentially arranged on the shaft on the bottom plate from top to bottom. The complete gear meshes with the fourth complete gear. A third rotating shaft is also arranged on the inner bottom plate of the housing.

The top end of the third rotating shaft extends out of the housing and is connected to a rotating frame located outside the housing. A second motor is arranged in the rotating frame. A speed governor is located in the rotating frame. The speed regulating knob of the speed governor is arranged outside the rotating frame. The control end of the speed governor is connected to the power supply end of the second motor. A second incomplete gear is connected to the output shaft of the second motor.

[0010] In this card dealer, the first motor drives the fourth complete gear to rotate. The fourth complete gear drives the incomplete gear set to rotate. The incomplete gear set drives the third complete gear to rotate. After the third complete gear rotates, the upper rotating frame rotates. The second motor in the rotating frame drives the second incomplete gear to rotate. The second incomplete gear drives the second complete gear in the rotating frame to rotate. The second complete gear drives the card pushing roller to pick out the cards in the lower card box. Each incomplete gear in the incomplete gear set corresponds to the number of players for a certain poker game. When the number of players changes, the third complete gear is toggled to make the third complete gear mesh with one of the incomplete gears in the incomplete gear set.

[0011] For the above-mentioned simple card dealer that can achieve precise card dealing, a calibration line is arranged on the surface of the uppermost incomplete gear of the incomplete gear set. The calibration line points from the center of the gear to the edge of the gear. When assembling the incomplete gear set, a tooth and non-tooth dividing line of all the incomplete gears in the incomplete gear set is located on the same vertical plumb line, which is convenient for unified calibration of all the incomplete gears. Since the third complete gear is located directly to the left of the incomplete gear set, during calibration, no matter which incomplete gear the third complete gear meshes with, as long as the calibration line of the uppermost incomplete gear is horizontally pointed to the 9 o'clock position, the calibration is completed, and precise card dealing can be further achieved after calibration.

[0012] For the above-mentioned simple card dealer that can achieve precise card dealing, a calibration handwheel is arranged at the top of the shaft of the incomplete gear set. During calibration, it can be inserted into the housing from above the housing through the calibration handwheel for calibration. In this solution, the top of the housing is an open structure.

Specific embodiments

[0030] Embodiment 1: A simple card dealer capable of accurately dealing cards comprises a housing 1, a first motor 2 is arranged on the inner bottom plate of the housing 1, a first incomplete gear 3 is connected to the output shaft of the first motor 2, a first complete gear 4 is also arranged on the inner bottom plate of the housing 1 through a vertical first rotating shaft, the first incomplete gear 3 is meshed with the first complete gear 4, the first rotating shaft is connected with a horizontally upward first toothed disc 5, the first toothed disc 5 is meshed with a first annular bearing 6, the intermediate shaft of the first annular bearing 6 is fixed in the inner ring of a bearing 7 arranged in the housing, the free end of the intermediate shaft of the first annular bearing 6 is an inner spline structure, the free end of the intermediate shaft of the second annular bearing 8 is an outer spline structure, the intermediate shaft of the second annular bearing 8 is slidably connected to the intermediate shaft of the first annular bearing 6, the second annular bearing 8 can slide left and right when toggled, and the second annular bearing 8 and the The second horizontally downward toothed disc 9 is meshed, and the second toothed disc 9 is connected to the second rotating shaft in the housing. The top of the second rotating shaft extends out of the housing and is connected to the rotating frame 10. The second toothed disc 9 is a three-layer toothed disc, and each layer of the toothed disc corresponds to a number of people playing cards. When the number of people playing cards changes, the second annular bearing 8 is manually toggled to allow the second annular bearing 8 to mesh with a certain layer of the toothed disc in the second toothed disc. A bearing toggle groove is provided on the front side of the housing 1 to facilitate the left and right toggle of the second annular bearing 8. A second motor 11 is provided in the rotating frame, and a second incomplete gear 13 is connected to the output shaft of the second motor 11. The second incomplete gear 13 is meshed with a second complete gear 14 provided on the horizontal axis. A card-pushing roller 15 is connected to the shaft of the second complete gear 14. A card box 16 is fixed to the bottom of the rotating frame, and the card box 16 is below the card-pushing roller 15.

[0031] When in use, the first motor 2 drives the first incomplete gear 3, and the first incomplete gear 3 drives the first complete gear 4 and the coaxial first tooth plate 5 to rotate. Due to the action of the first incomplete gear 3, the first tooth plate 5 pauses every time it rotates 180 degrees. The first tooth plate 5 and the second tooth plate 9 are driven by an annular bearing. The second tooth plate 9 pauses every time it rotates 120 degrees when there are 3 players (corresponding to the first layer of the tooth plate); pauses every time it rotates 90 degrees when there are 4 players (corresponding to the second layer of the tooth plate); and pauses every time it rotates 72 degrees when there are 5 players (corresponding to the third layer of the tooth plate). The transmission ratio of the first tooth plate 5 to the second tooth plate 9 is as follows: when there are 3 players, the transmission ratio of the first layer of the tooth plate in the first tooth plate 5 and the second tooth plate is 1.5, when there are 4 players, the transmission ratio of the second layer of the tooth plate in the first tooth plate 5 and the second tooth plate is 2; when there are 5 players, the transmission ratio of the third layer of the tooth plate in the first tooth plate 5 and the second tooth plate is 2.5. According to the change of the transmission ratio, the number of notches of the tooth plate can be set. By determining the number of notches of the first tooth plate 5, the number of notches of the second tooth plate 9 can be set. Assume that the number of notches in the first toothed disc 5 is 12, and the number of notches in the three layers of the second toothed disc 9 is 18, 24, and 30 respectively.

[0032] When three people play, the first sprocket 5 rotates 180 degrees and the second sprocket 9 rotates 120 degrees. If the second sprocket 9 rotates 360 degrees, the second complete gear 14 and the card-pushing roller rotate 3 circles to draw 3 cards. Therefore, the rotational speed of the card-pushing roller should be adjusted to 3 times that of the second sprocket 9. Since the transmission ratio of the second incomplete gear 13 and the second complete gear 14 is 1, the rotational speed of the second incomplete gear 13 is adjusted to 3 times that of the second sprocket 9. Assuming the rated rotational speed of the first motor is 240 revolutions per minute and the first motor operates at the rated speed, and the diameters of the first incomplete gear 3 and the first complete gear 4 are equal with a transmission ratio of 2, the rotational speed of the second sprocket 9 is calculated as follows: When three people play, the rotational speed of the second sprocket 9 is 80 revolutions per minute (240 revolutions per minute ÷ the transmission ratio 2 of the first incomplete gear 3 and the first complete gear ÷ the transmission ratio 1.5 of the innermost layers of the first sprocket 5 and the second sprocket 9 = 80); when four people play, the rotational speed of the second sprocket 9 is 60 revolutions per minute; when five people play, the rotational speed of the second sprocket 9 is 48 revolutions per minute. For the corresponding rotational speeds of the card-pushing roller and the second motor 11, when there are three players, the rotational speed of the second motor 11 is 3 times that of the second sprocket 9, which is 80 revolutions per minute × 3 = 240 revolutions per minute. When four people play, the rotational speed of the second motor 11 should be 4 times that of the second sprocket 9, that is, 60 revolutions per minute × 4 = 240 revolutions per minute. When there are five people, the rotational speed of the second motor 11 should be 5 times that of the second sprocket 9, 48 revolutions per minute × 5 = 240 revolutions per minute. Thus, it can be seen that as long as the rated rotational speeds of the first motor and the second motor 11 are the same, the card-dealing task for different numbers of players can be completed.

[0033] Sprockets and annular bearings are existing power transmission structures, commonly seen in the transmission structure of chainless variable-speed bicycles.

[0034] Embodiment 2: A simple card dealer capable of accurately dealing cards, comprising a housing 1, a first motor 2 is arranged on the inner bottom plate of the housing 1, a fourth complete gear 25 is connected to the output shaft of the first motor 2, an incomplete gear set is also vertically arranged on the inner bottom plate of the housing 1, the incomplete gear set comprises three incomplete gears 17 and one complete gear 18, the three incomplete gears 17 and the complete gear 18 are arranged on the shaft on the bottom plate from top to bottom, the complete gear 18 is meshed with the fourth complete gear 25, a third rotating shaft is also arranged on the inner bottom plate of the housing, a key hole is arranged on the third complete gear 19, a keyway shaft is arranged on the third rotating shaft, the third complete gear 19 is slidably arranged on the third rotating shaft, the third complete gear 19 is meshed with one of the incomplete gears 17, the top end of the third rotating shaft extends out of the housing 1 and is connected to the rotating frame 10 located outside the housing, and a third rotating shaft 25 is arranged on the housing 1. A gear toggle slot is provided to facilitate the up and down toggle of the third complete gear 19. Each incomplete gear 17 in the incomplete gear set corresponds to a number of people playing poker cards. When the number of people playing cards changes, the third complete gear 19 is manually toggled to allow the third complete gear 19 to mesh with a certain incomplete gear 17 in the incomplete gear set. A second motor 11 is provided in the rotating frame 10, and a speed regulator 12 is located in the rotating frame. The speed knob of the speed regulator 12 is arranged outside the rotating frame. The control end of the speed regulator 12 is connected to the power supply end of the second motor 11. A second incomplete gear 13 is connected to the output shaft of the second motor 11. The second incomplete gear 13 is meshed with a second complete gear 14 arranged on a horizontal axis. A card-pushing roller 15 is connected to the shaft of the second complete gear 14. A card box 16 is fixed to the bottom of the rotating frame. The card box 16 is below the card-pushing roller 15.

[0035] When the diameter of the third complete gear 19 is half of the diameter of the incomplete gear 17, assuming that the transmission ratio of the fourth complete gear 25 and the complete gear 18 is 10, due to the structure of the incomplete gear 17 with teeth on one half and no teeth on the other half, the actual transmission ratio with the third complete gear 19 is 1. Thus, the actual transmission ratio from the fourth complete gear 25 to the third complete gear 19 is calculated to be 10. If the rotational speeds of the first motor 2 and the second motor 11 are the same, during the meshing transmission between the second incomplete gear 13 on the second motor 11 (with teeth on one half and no teeth on the other half) and the second complete gear 14 coaxial with the card-pushing roller, the second complete gear 14 will pause for half of the time. Therefore, the actual transmission ratio between the second incomplete gear 13 and the second complete gear 14 is 1. When three people play, the fourth complete gear 25 rotates 10 circles, the complete gear 18 rotates 1 circle, and the incomplete gear 17 and the middle third complete gear 19 also rotate 1 circle to deal 3 cards. The rotation frame rotates according to the following rules: when three people play, the rotation frame rotates 120 degrees to deal each card and pauses for the same time as it takes to rotate through this angle; when four people play, the rotation frame rotates 90 degrees and pauses to deal each card; when five people play, the rotation frame rotates 72 degrees and pauses to deal each card. When three people play, the third complete gear 19 rotates 1 circle to deal 3 cards, the first motor rotates 10 circles, and the card-pushing roller deals 1 card for every 360-degree rotation. Then, to deal 3 cards, the card-pushing roller and the second motor need to rotate 1080 degrees. Therefore, the rotational speed of the second motor should be 3 times the rotational speed of the second complete gear. Since the initial rotational speed of the second motor is 10 times that of the second complete gear, adjusting the speed regulator knob to the 30% position can complete the corresponding card-dealing task. When four people play, the rotation frame rotates 1 circle to deal 4 cards, and the corresponding second motor rotates 1440 degrees. So, adjust the speed regulator to the 40% position. When five people play, the rotation frame rotates 1 circle to deal 5 cards, and the corresponding second motor rotates 1800 degrees. So, adjust the speed regulator to the 50% position.

[0036] When the diameter of the third complete gear 19 is equal to the diameter of the incomplete gear 17, then for every two rotations of the incomplete gear set, the third complete gear 19 rotates 1 circle, and the transmission ratio is 2. For every two rotations of the incomplete gear, the rotation frame rotates 1 circle. In this case, the number of pauses of the rotation frame is twice the original, and it can accommodate twice the original number of players. The number of players (i.e., the ratio of the number of rotations of the card-pushing roller to the number of rotations of the rotation frame) ÷ the product of the two transmission ratios (the transmission ratio of the fourth complete gear 25 and the complete gear 18 is 10, and the transmission ratio of the incomplete gear set 17 and the third complete gear 19 is 2) = the speed regulation ratio of the second motor. The following conclusions can be drawn: when there are 6 players, adjust the speed regulator to 30%; when there are 8 players, adjust the speed regulator to 40%; when there are 10 players, adjust the speed regulator to 50%... If the transmission ratio of the fourth complete gear 25 and the complete gear 18 is 5 and the transmission ratios of other gears remain unchanged, adjust the speed regulator to 60%, 80%, and 100% to accommodate 3 or 6, 4 or 8, and 5 or 10 players respectively.

[0037] Embodiment 3: A simple card dealer that can achieve precise card dealing, including a housing 1. Inside the housing 1, there is a single-chip microcomputer 23 with a timer and a servo 24. Both the single-chip microcomputer 23 and the servo 24 are located inside the housing 1. The timer is set outside the housing. The single-chip microcomputer 23 is connected to the servo 24. The output shaft of the servo 24 is connected to a rotating frame 10 located outside the housing. Inside the rotating frame, there is a second motor 11. A speed governor 12 is located inside the rotating frame. The speed regulation knob of the speed governor 12 is set outside the rotating frame. The control end of the speed governor 12 is connected to the power supply end of the second motor 11. A semi-circular card pushing roller 15 is connected to the output shaft of the second motor 11. A card box 16 is fixed to the bottom inside the rotating frame. The card box 16 is below the card pushing roller 15.

[0038] For different numbers of players, the time taken for the servo to rotate by a corresponding angle each time (the timer sets the pause time each time to be the same as the time taken to rotate a certain angle) is different. According to this corresponding time, when the rotational speed of the second motor × 2 times the corresponding time × the speed regulation value of the speed governor 12 = 1 circle (the card pushing roller rotates 360 degrees), it is okay.

[0039] Embodiment 4: A simple card dealer that can achieve precise card dealing, including a housing 1. Inside the housing 1, there is a single-chip microcomputer 23 with a timer and a servo 24. Both the single-chip microcomputer 23 and the servo 24 are located inside the housing 1. The timer is set outside the housing. The single-chip microcomputer 23 is connected to the servo 24. The output shaft of the servo 24 is connected to a rotating frame 10 located outside the housing. Inside the rotating frame 10, there is a second motor 11. A speed governor 12 is located inside the rotating frame. The speed regulation knob of the speed governor 12 is set outside the rotating frame. The control end of the speed governor 12 is connected to the power supply end of the second motor 11. A second incomplete gear 13 is connected to the output shaft of the second motor 11. The second incomplete gear 13 meshes with a second complete gear 14 arranged on a horizontal shaft. A card pushing roller 15 is connected to the shaft of the second complete gear 14. A card box 16 is fixed to the bottom inside the rotating frame. The card box 16 is below the card pushing roller 15.

[0040] For different numbers of players, the time taken for the servo to rotate by a corresponding angle each time (the timer sets the pause time each time to be the same as the time taken to rotate a certain angle) is different. When the rotational speed of the second motor × 2 times the corresponding time × the speed regulation value of the speed governor 12 = 1 circle (the incomplete gear 13 rotates 360 degrees, driving the complete gear 14 and the card pushing roller to rotate 360 degrees), it is okay.

[0041] Embodiment 5: A simple card dealer capable of achieving precise card dealing, comprising a housing 1. A first motor 2 is provided on the inner bottom plate of the housing 1. A fourth complete gear 25 is connected to the output shaft of the first motor 2. An incomplete gear set is also vertically provided on the inner bottom plate of the housing 1. The incomplete gear set includes three incomplete gears 17 and a complete gear 18. The three incomplete gears 17 and the complete gear 18 are sequentially arranged on the shaft on the bottom plate from top to bottom. The complete gear 18 meshes with the fourth complete gear 25. A third rotating shaft is also provided on the inner bottom plate of the housing 1. A third complete gear 19 capable of sliding thereon is provided on the third rotating shaft. The third complete gear 19 meshes with one of the incomplete gears 17. The top end of the third rotating shaft extends out of the housing and is connected to a rotating frame 10 located outside the housing. A second motor 11 is provided in the rotating frame 10. A speed regulator 12 is located in the rotating frame. The speed regulating knob of the speed regulator 12 is provided outside the rotating frame. The control end of the speed regulator 12 is connected to the power supply end of the second motor 11. A semi-circular card pushing roller 15 is connected to the output shaft of the second motor 11. A card box 16 is fixed to the inner bottom of the rotating frame 10. The card box 16 is below the card pushing roller 15. A proofreading handwheel 26 is provided at the top of the shaft of the incomplete gear set.

[0042] When the diameter of the third complete gear 19 is half of the diameter of the incomplete gear 17, assuming that the transmission ratio of the fourth complete gear 25 and the complete gear 18 is 10, due to the structure of the incomplete gear 17 with teeth on one half and no teeth on the other half, the transmission ratio with the third complete gear 19 is 1. Thus, the actual transmission ratio from the fourth complete gear 25 to the third complete gear 19 is calculated to be 10. The semi-circular card-pushing roller rotates half a turn to deal one card, then rotates half a turn without dealing a card and returns to the initial position, repeating this process. If the initial rotational speeds of the first motor 2 and the second motor 11 are the same, when three people play, the fourth complete gear 25 rotates 10 circles, the complete gear 18 rotates 1 circle, and the incomplete gear 17 and the middle third complete gear 19 also rotate one circle to deal 3 cards. The rotating frame rotates according to the following rules: when three people play, the rotating frame rotates 120 degrees to deal each card and pauses for the same amount of time as it takes to rotate through this angle; when four people play, the rotating frame rotates 90 degrees and pauses to deal each card; when five people play, the rotating frame rotates 72 degrees and pauses to deal each card. When three people play, the third complete gear 19 rotates one circle to deal 3 cards, the first motor rotates 10 circles, and the card-pushing roller deals one card for every 360-degree rotation. For dealing 3 cards, the card-pushing roller and the second motor need to rotate 1080 degrees. Then the rotational speed of the second motor should be 3 times the rotational speed of the second complete gear. Since the initial rotational speed of the second motor is 10 times that of the second complete gear, adjusting the speed regulator knob to the 30% position can complete the corresponding card-dealing task. When four people play, the rotating frame rotates one circle to deal 4 cards, and the corresponding second motor rotates 1440 degrees. So, adjust the speed regulator to the 40% position. When five people play, the rotating frame rotates one circle to deal 5 cards, and the corresponding second motor rotates 1800 degrees. So, adjust the speed regulator to the 50% position.

[0043] When the diameter of the third complete gear 19 is equal to the diameter of the incomplete gear 17, then for every two rotations of the incomplete gear set, the third complete gear 19 rotates one circle, and the transmission ratio is 2. For every two rotations of the incomplete gear, the rotating frame rotates one circle. In this case, the number of pauses of the rotating frame is twice the original, and it can accommodate twice the original number of players. The number of players (i.e., the ratio of the number of rotations of the card-pushing roller to the number of rotations of the rotating frame) ÷ the product of the two transmission ratios (the transmission ratio of the fourth complete gear 25 and the complete gear 18 is 10, and the transmission ratio of the incomplete gear set 17 and the third complete gear 19 is 2) = the speed regulation ratio of the second motor. The following conclusions can be drawn: when there are 6 players, adjust the speed regulator to 30%; when there are 8 players, adjust the speed regulator to 40%; when there are 10 players, adjust the speed regulator to 50%...; if the transmission ratio of the fourth complete gear 25 and the complete gear 18 is 5 and the transmission ratios of other gears remain unchanged, adjust the speed regulator to 60%, 80%, and 100% respectively to accommodate 3 or 6, 4 or 8, and 5 or 10 players.
