Abstract
Description
Technical Field
[0001] This utility model relates to the field of card dealing machine technology, and in particular to an automatic card dealing machine. Background Technology
[0002] A series of patent documents, including CN218923750U, CN115845352A, CN116212357A, and CN116236765A, disclose an automatic card dealing machine. The machine includes a housing with a card holder, a card inlet located at the bottom front of the card holder, a card feeding mechanism for delivering the cards from the card holder to the card inlet, and a card dispensing mechanism located on the outside of the housing corresponding to the card inlet, dispensing the cards from the card inlet through the card dispensing mechanism. The card feeding mechanism includes a first card feeding roller assembly located at the bottom inner side of the card holder and near the front end of the cards, a second card feeding roller assembly located at the bottom inner side of the card holder and near the rear end of the cards, a first motor, and a first transmission assembly for transmitting power from the motor to the first and second card feeding roller assemblies. The machine also includes a rotating base that can rotate relative to the housing, allowing the card dealing machine to deal cards in different directions.
[0003] Existing card dealing machines typically set the height of the card inlet to between the thickness of one and two playing cards, enabling the machine to deal cards one by one. However, such machines may fail to deal cards or deal too many cards when dealing with playing cards of varying thicknesses, impacting the user experience. Currently, some card dealing machines exist that can adjust the inlet height to accommodate playing cards of different thicknesses. For example, patent document CN212757180U discloses a solution that adjusts the inlet height by setting an adjustable limit plate. However, when dealing with used playing cards, which may have bent or deformed due to use, the machine may experience uneven card dealing or card jamming, affecting its stability.
[0004] To address this, patent document CN116236765A discloses another limiting mechanism to accommodate playing cards of different thicknesses and those slightly bent due to use. This limiting mechanism includes a lower scoring card block located at the lower center of the card inlet, an adjusting device for adjusting the height of the lower scoring card block, and an upper scoring card block located above the card inlet corresponding to the lower scoring card block. The adjusting device includes an adjusting cavity, an adjusting spring disposed within the adjusting cavity with one end abutting the bottom of the adjusting cavity and the other end abutting the lower scoring card block, an adjusting hole vertically disposed within the adjusting cavity, and an adjusting screw with one end connected to the lower scoring card block and the other end inserted into the adjusting hole. The height of the lower scoring card block is adjusted by adjusting the depth of the adjusting screw inserted into the adjusting hole, thereby achieving height adjustment of the card inlet. However, the upper scoring block is fixed and the scoring is done only by the inclined plane, which is not ideal. The lower scoring block is upper limited by the adjusting screw and the lower scoring block is lifted up by the spring. When multiple playing cards are firmly attached to each other and enter the card inlet, the spring may be compressed, which will change the card inlet gap and cause two playing cards or cards to enter the card outlet channel and block it. Summary of the Invention
[0005] To address the aforementioned problems, the present invention aims to provide an automatic card dealing machine that uses a card feeding wheel and a card feeding pressure wheel to limit the number of playing cards entering the card inlet of the card dealing machine. Combined with a card gap structure with upper and lower card blocks set inside the card inlet, this prevents two or more playing cards from entering the card dispensing channel at the same time, thus avoiding card blockage.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An automatic card dealing machine includes a fixed base, a rotating base, and a housing. The housing has a card compartment for holding playing cards, a card inlet located at the bottom front of the card compartment, and a card outlet located on the outside of the housing corresponding to the card inlet, forming a card dispensing channel between the card inlet and the card outlet. The rotating base is rotatably mounted on the fixed base. The machine further includes: a card dispensing wheel assembly located below the card outlet, the card dispensing wheel assembly including at least one card dispensing wheel; a card dispensing pressure wheel assembly located above the card outlet, the card dispensing pressure wheel assembly including at least one card dispensing pressure wheel vertically corresponding to the card dispensing wheel in the card dispensing wheel assembly; and a first card feeding wheel assembly located at the bottom of the card compartment, the first card feeding wheel assembly including at least one card feeding wheel. A card-feeding wheel; a second card-feeding wheel assembly located below the card-feeding inlet, the second card-feeding wheel assembly including at least one card-feeding wheel; a card-feeding pressure wheel assembly located above the card-feeding inlet, the card-feeding pressure wheel assembly including at least one card-feeding pressure wheel vertically corresponding to the card-feeding wheel in the second card-feeding wheel assembly; an upper scoring baffle and a lower scoring block located in the card-dispensing channel between the card-feeding inlet and the card-dispensing inlet and near the card-feeding inlet, the upper scoring baffle and the lower scoring block vertically corresponding to each other and forming a card-feeding gap between them for the passage of playing cards; a card-dealing motor and a transmission assembly for transmitting the power of the card-dealing motor to the first card-feeding wheel assembly, the second card-feeding wheel assembly and the card-dispensing wheel assembly.
[0008] Preferably, the transmission assembly includes a first synchronous belt, a second synchronous belt, and a third transmission belt. The first card feeding wheel assembly and the second card feeding wheel assembly are connected by the first synchronous belt, the second card feeding wheel assembly and the card dispensing wheel assembly are connected by the second synchronous belt, and the card dispensing wheel assembly is connected to the card dealing motor by the third transmission belt. The rotational speed of the card dispensing wheel assembly is greater than the rotational speed of the first card feeding wheel assembly and the second card feeding wheel assembly.
[0009] Preferably, the card-feeding pressure roller assembly includes a card-feeding pressure roller that can float up and down on the card-dealing bracket. The card-feeding pressure roller is mounted on a card-feeding pressure roller shaft. Both ends of the card-feeding pressure roller shaft are mounted on the card-dealing bracket via card-feeding pressure roller springs and pressure plates. The card-dealing bracket is fixed on a rotating seat, and the card-dealing motor is fixed on the card-dealing bracket. One end of the card-feeding pressure roller spring abuts against the card-feeding pressure roller shaft, and the other end of the card-feeding pressure roller spring abuts against the pressure plate, thereby pressing the card-feeding pressure roller mounted on the card-feeding pressure roller shaft toward the card-feeding roller.
[0010] Preferably, the second card feeding wheel assembly includes two card feeding wheels, the card feeding pressure wheel assembly includes two card feeding pressure wheels, the upper card baffle is disposed between the two card feeding pressure wheels, and the lower card block is disposed between the two card feeding wheels in the second card feeding wheel assembly.
[0011] Preferably, the first card feeding wheel assembly is a non-circular card feeding wheel; the card feeding wheel assembly has multiple first protruding ridges protruding on its circumference; the card feeding wheel assembly is made of elastic material and has multiple holes and grooves hollowed out inside; the first protruding ridges and holes and grooves are arranged correspondingly inside and outside.
[0012] Preferably, the first card feeding wheel assembly has multiple second protruding ridges protruding from the circumference of the card feeding wheel, and multiple second protruding ridges are provided between two first protruding ridges, with the protrusion height of the first protruding ridges being higher than the protrusion height of the second protruding ridges.
[0013] Preferably, an auxiliary wheel assembly is provided between the first card-feeding wheel assembly and the second card-feeding wheel assembly.
[0014] Preferably, the card-dispensing pressure roller assembly includes a card-dispensing pressure roller that is mounted on a card-dispensing bracket and can float up and down. The card-dispensing pressure roller is mounted on a spring shaft and can rotate.
[0015] As a preferred option, several sensors for detecting playing cards are installed in the card-dispensing channel.
[0016] Preferably, a battery is installed on a fixed base, a rotating base, or a housing, and the battery is connected to a control circuit board or a charging port via a wire; the charging port is located on the rotating base.
[0017] This invention, by employing the above technical solution, sets up a second card-feeding wheel assembly and a card-feeding pressure wheel assembly at the card-feeding channel's inlet, which are driven and rotate in the same direction as the card-feeding wheel assembly. This not only enables rapid card ejection and distribution when needed but also limits the number of playing cards entering the card-feeding channel, preventing multiple playing cards from simultaneously entering the gap between the upper and lower scoring blocks and causing card jamming. Furthermore, by adjusting the size of the card-feeding gap, the number of playing cards entering the inlet at a time is limited to one, ensuring that playing cards are distributed one by one.

[0037] like Figure 1 and Figure 2 An automatic card dealing machine is shown, comprising a fixed base 1, a rotating base 2, and a housing 3. The housing 3 is provided with a card compartment 302 for holding playing cards, a card inlet 303 located at the bottom front of the card compartment 302, and a card outlet 301 located on the outside of the housing corresponding to the card inlet. Playing cards in the card compartment 302 are dispensed from the card outlet 301 through the card inlet 303. The rotating base 2 is equipped with a card feeding mechanism for feeding the playing cards in the card compartment into the card inlet and a card dispensing mechanism for dispensing the playing cards that have entered the card inlet from the card outlet. The rotating base 2 is rotatably mounted on the fixed base 1, thereby allowing the card dealing machine to deal cards in different directions.
[0038] In this embodiment, the upper part of the housing 3 is recessed to form a card holder 302. The top and rear of the card holder 302 are open structures, so that the length of the playing cards placed in the card holder 302 can exceed the length of the card holder 302, which can be adapted to more types of playing cards.
[0039] In this embodiment, as Figures 3 to 7 As shown, the card dealing mechanism mounted on the rotating base 2 includes: a card dealing wheel assembly 216 located below the card dispensing port 301, the card dispensing wheel assembly 216 including at least one card dispensing wheel; a card dispensing pressure wheel assembly 215 located above the card dispensing port 301 and pressing against the card dispensing wheel assembly 216, the card dispensing pressure wheel assembly 215 including at least one card dispensing pressure wheel arranged vertically corresponding to the card dispensing wheel in the card dispensing wheel assembly 216; and a card dealing motor 209 that provides power to the card dispensing wheel assembly 216.
[0040] In this embodiment, the card feeding mechanism is mounted on the rotating base 2 and is used to feed the playing cards in the card compartment into the card inlet. It includes: a first card feeding wheel assembly 201 located at the bottom of the card compartment, the first card feeding wheel assembly 201 including at least one card feeding wheel; a second card feeding wheel assembly 204 located below the card inlet 303, the second card feeding wheel assembly 204 including at least one card feeding wheel; a card feeding pressure wheel assembly 205 located above the card inlet 303 and pressing on the second card feeding wheel assembly 204, the card feeding pressure wheel assembly 205 including at least one card feeding pressure wheel corresponding to the card feeding wheel in the second card feeding wheel assembly 204; and a transmission assembly that transmits the power of the card dealing motor 209 to the first card feeding wheel assembly 201 and the second card feeding wheel assembly 204.
[0041] In this embodiment, an upper scoring baffle 217 and a lower scoring block 218 are provided between the second card feeding wheel assembly 204 and the card dispensing wheel assembly 216 (in the card dispensing channel between the card inlet 303 and the card outlet 301 and close to the card inlet). The upper scoring baffle 217 and the lower scoring block 218 are arranged vertically and vertically, forming a card inlet gap between them. By adjusting the size of the card inlet gap, the number of playing cards entering the card inlet at one time can be limited to ensure that the playing cards are dispensed one by one.
[0042] In this way, by setting a second card feeding wheel assembly 204 and a card feeding pressure wheel assembly 205 at the card inlet of the card dispensing channel, which are connected to the card dispensing wheel assembly 216 and rotate in the same direction, not only can the card be quickly ejected when needed, but the number of playing cards entering the card dispensing channel can also be limited, further avoiding the jamming and blockage caused by multiple playing cards entering the card inlet gap between the upper scoring card baffle 217 and the lower scoring card block 218 at the same time.
[0043] In this embodiment, the card-feeding wheel assembly is disposed on the bottom surface of the card compartment 302, and includes: a card-feeding shaft parallel to the card inlet 303, and a card-feeding wheel that contacts the bottom surface of the playing cards to perform the card-feeding function. The card-feeding wheel is fixed on the card-feeding shaft, which is mounted and fixed on the rotating seat 2 by bearings at both ends, so that the card-feeding wheel can rotate with the card-feeding shaft to complete the card-feeding. In this embodiment, the first card-feeding wheel assembly 201 has two card-feeding wheels, and the second card-feeding wheel assembly 204 has two card-feeding wheels, respectively disposed on the left and right sides of the playing cards. In other embodiments, the card-feeding wheel assembly may have one or more card-feeding wheels.
[0044] In this preferred embodiment, the first card feeding wheel assembly 201 and the second card feeding wheel assembly 204 are both mounted on the rotating base 2, and the housing 3 is fixed above the rotating base 2. The housing 3 has openings at the bottom of the card compartment that correspond one-to-one with each card feeding wheel. The top of each card feeding wheel extends into the card compartment through the opening and rubs against the playing cards at the bottom of the card compartment.
[0045] In this embodiment, the card-dispensing wheel assembly 216 includes a card-dispensing shaft parallel to the card-dispensing opening and a card-dispensing wheel that rubs against the bottom surface of the playing cards to achieve the card-dispensing function. The card-dispensing wheel is fixed on the card-dispensing shaft, and the card-dispensing shaft is assembled to the frame on the rotating seat 2 through bearings at both ends. One end of the card-dispensing shaft is connected to the card-dispensing motor 209 through a third synchronous belt 213, so that the card-dispensing wheel can rotate relative to the rotating seat 2 to complete the card-dispensing.
[0046] In this preferred embodiment, such as Figure 7 As shown, the card-dispensing pressure roller assembly 215 includes a card-dispensing pressure roller that can float up and down on the card-dealing bracket 208. The card-dispensing pressure roller is mounted on a spring shaft and can rotate. In other embodiments, the card-dispensing pressure roller can also be sleeved on the card-dispensing pressure roller shaft. The card-dispensing pressure roller spring, which is located in the spring cavity on the card-dealing bracket, elastically abuts against the card-dispensing pressure roller shaft. That is, one end of the card-dispensing pressure roller spring abuts against the top of the spring cavity, and the other end abuts against the card-dispensing pressure roller shaft, pressing the card-dispensing pressure roller sleeved on the card-dispensing pressure roller shaft against the card-dispensing wheel. The card-dispensing pressure roller and the card-dispensing pressure roller shaft can rotate relative to each other, increasing the friction between the playing cards and the card-dispensing wheel without increasing the resistance to card dispensing. In this way, the up-and-down floating card-dispensing pressure roller can compensate for the uncertainty of the thickness and surface condition of the playing cards, achieving smooth and uniform card dispensing.
[0047] In this embodiment, the upper card deflector 217 is fixed to the card dealing bracket 208 with screws and can be adjusted up and down. The lower card block 218 can be pushed upwards by a spring and limited to its upper limit, or it can be limited downwards by a lever structure. For details, please refer to the adjustable card inlet height structure disclosed in patent documents such as CN116212357A, CN116236765A, and CN117732034A. In other embodiments, the lower card block 218 can also be fixed to the rotating base with screws and can be adjusted up and down.
[0048] In this embodiment, the width of the lower scoring card block is 1 / 6 of the width of a playing card. In other embodiments, the width of the lower scoring card block can also be 1 / 8, 1 / 7, 1 / 5, 1 / 4, 1 / 3, or 1 / 2 of the width of a playing card. The width of the upper scoring card block is similar to or slightly smaller than that of the lower scoring card block.
[0049] In this embodiment, as Figure 7 As shown, the card-dispensing channel of the rotating seat 2 is equipped with several sensors 219 for detecting playing cards. These sensors 219 are preferably photosensitive sensors such as infrared tubes.
[0050] In this embodiment, as Figure 6 As shown, a shaft portion protrudes downward from the center of the bottom of the rotating base 2, and a bearing is fitted onto the shaft portion. The bearing is mounted at the center of the fixed disk 203, which is mounted on the fixed base 1. A rotary motor 207 is mounted on the rotating base 2, and the rotary motor 207 is connected to the fixed disk 203 for transmission. In this way, the rotary motor 207 drives the rotating base 2 and its housing 3 to rotate around the fixed disk 203. For specific structures, please refer to patent documents disclosed in CN116212357A, CN116236765A, and CN117732034A.
[0051] In this embodiment, as Figure 2 As shown, a battery is installed on the fixed base 1, the rotating base 2, or the housing 3, and the battery is connected to the control circuit board or the charging port via a wire. The charging port 101 is located on the rotating base 2.
[0052] In this preferred embodiment, the transmission assembly includes a first synchronous belt 211, a second synchronous belt 212, and a third transmission belt 213. The first card feeding wheel assembly 201 and the second card feeding wheel assembly 204 are connected by the first synchronous belt 211. The second card feeding wheel assembly 204 and the card dispensing wheel assembly 216 are connected by the second synchronous belt 212. The card dispensing wheel assembly 216 is connected by the third transmission belt 213 to the card dispensing motor 209. The rotational speed of the card dispensing wheel assembly 216 is greater than the rotational speed of the first card feeding wheel assembly 201 and the second card feeding wheel assembly 204 to facilitate fast and accurate card dispensing.
[0053] In this preferred embodiment, the first card-feeding wheel assembly 201 is a non-circular card-feeding wheel. This allows the playing cards to move up and down intermittently, resulting in better card distribution. Further preferred, such as... Figure 8 and Figure 9 As shown, the first card-feeding wheel assembly 201 has multiple protruding first ridges 2011 on its circumference. The card-feeding wheel itself is made of elastic material and has multiple hollowed-out slots 2013. The first ridges 2011 and slots 2013 are correspondingly arranged inside and out. Thus, when the first card-feeding wheel assembly feeds a large stack of playing cards, the slots can buffer the impact between the first cam and the playing cards, thereby reducing noise.
[0054] In this embodiment, the elastic material can be rubber, nylon, etc. The elastic material is fixedly connected to the card delivery wheel axle by injection molding or bonding.
[0055] In this preferred embodiment, the first card feeding wheel assembly 201 has a plurality of second protruding ridges 2012 protruding on the circumference of the card feeding wheel, and a plurality of second protruding ridges 2012 are provided between two first protruding ridges 2011, wherein the protrusion height of the first protruding ridge 2011 is higher than the protrusion height of the second protruding ridge 2012.
[0056] In this preferred embodiment, an auxiliary wheel assembly 202 is provided between the first card delivery wheel assembly 201 and the second card delivery wheel assembly 204. The auxiliary wheel has no power, which facilitates the transfer of playing cards.
[0057] In this preferred embodiment, such as Figure 7 As shown, the card-feeding pressure roller assembly 205 includes a card-feeding pressure roller that can float up and down on the card-dealing bracket 208. The card-feeding pressure roller is mounted on a card-feeding pressure roller shaft. Both ends of the card-feeding pressure roller shaft are mounted on the card-dealing bracket 208 via card-feeding pressure roller springs 2052 and pressure plates 2051. The card-dealing bracket 208 is fixed on the rotating seat 2, and the card-dealing motor 209 is fixed on the card-dealing bracket 208. One end of the card-feeding pressure roller spring 2052 abuts against the card-feeding pressure roller shaft, and the other end abuts against the pressure plate 2051, thereby pressing the card-feeding pressure roller mounted on the card-feeding pressure roller shaft against the card-feeding wheel. The card-feeding pressure roller and the card-feeding pressure roller shaft can rotate relative to each other, increasing the friction between the playing cards and the card-feeding wheel without increasing the resistance to card feeding.
[0058] In this preferred embodiment, such as Figure 5 As shown, the second card-feeding wheel assembly 204 has two card-feeding wheels, and the card-feeding pressure wheel assembly 205 has two corresponding card-feeding pressure wheels. The upper scoring baffle 217 is positioned between the two card-feeding pressure wheels, and the lower scoring block 218 is positioned between the two card-feeding wheels in the second card-feeding wheel assembly 204. In this way, the card-feeding wheels, the card-feeding pressure wheels, the upper scoring baffle, and the lower scoring block are staggered, allowing multiple playing cards that are pressed together at different heights to be effectively separated, thus improving card distribution and preventing card jamming.
