Description

Technical Field

[0001] The utility model relates to the technical field of card dealing machines, in particular to a differential separation card dealing machine. Background Art

[0002] As living standards improved, people's daily lives became more enriched, and playing poker became a popular pastime. However, after a round, players had to sort, shuffle, and deal the cards themselves. To save time, automatic card dealing machines were invented.

[0003] In existing card dealing machines, the speed of the dealing wheel is usually faster than that of the card feeding wheel. However, when the playing cards touch the dealing wheel and the card feeding wheel at the same time, the playing cards will drag the dealing wheel, which means that the card feeding wheel will be dragged down. This not only increases power loss but also affects the smoothness of card dealing.

[0004] In response to this, some card dealing machines have added a one-way bearing between the dealing wheel and the card feeding wheel. This can cut off the power transmission between the dealing wheel and the card feeding wheel under appropriate circumstances, ensure the working stability of the dealing wheel and the card feeding wheel, reduce power loss, and improve the operating efficiency and smoothness of the equipment.

[0005] However, the high cost of one-way bearings is a considerable burden for the mass production of card-dealing machines and urgently needs to be improved. Utility Model Content

[0053] The present invention will be described in further detail below with reference to the accompanying drawings.

[0054] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0055] For ease of understanding and description, the card-delivering direction of the card-delivering machine is referred to as the front-to-back direction hereinafter, wherein the direction in which the cards are delivered is referred to as the front.

[0056] This embodiment relates to a differential separation card dealing machine, referring to Figure 1-Figure 4 , including: a housing 100, a card feeding mechanism 200 and a card dealing mechanism 300.

[0057] Among them, reference Figures 1-6 The housing 100 includes a card bin 110 for accommodating cards, card access ports 120 located on the top and / or rear and / or left and right sides of the card bin 110, a card delivery port 130 located on the front side of the card bin 110, and a card dealing port 140 located on the front side of the housing 100 and corresponding to the card delivery port 130. A card delivery mechanism 200 is disposed at the bottom or top of the card bin 110 and is used to deliver cards in the card bin 110 to the card delivery port 130. A card dealing mechanism 300 is disposed between the card delivery port 130 and the card dealing port 140 and is used to deliver cards passing through it from the card dealing port 140.

[0058] Specifically in this embodiment, refer to Figures 1-6 The card dealing machine is an upper card dealing machine, the card delivery port 130 is located on the upper front side of the card bin 110, and the card retrieval port 120 is located on the top and rear sides of the card bin 110. The upper card dealing machine also includes: a card holding plate 410 arranged in the card bin 110 for holding cards; and a card holding elastic member 420 arranged between the card holding plate 410 and the bottom of the card bin 110. The card delivery mechanism 200 is located above the card holding plate 410. A stack of cards is placed in the card bin 110 and is supported by the card holding plate 410 to the lower side of the card delivery mechanism 200. When dealing cards, the card delivery mechanism 200 rolls the top card into the subsequent card dealing mechanism 300 for dealing. In some embodiments, the card retrieval port 120 can also be opened on the left or right side.

[0059] In other embodiments (not shown), the card dealer can also be a bottom-loading card dealer, with the card delivery port located at the lower front side of the card bin. The card delivery mechanism is located above the card bin. A stack of cards is placed in the card bin and pressed against the upper side of the card delivery mechanism. When dealing cards, the card delivery mechanism reels the bottommost card into the subsequent card dealing mechanism for further dealing.

[0060] The following embodiments all take the upper card dealing machine as an example, but unless otherwise specified, they are also applicable to the lower card dealing machine.

[0061] In some embodiments, reference Figure 5-Figure 8The card-delivering mechanism 300 includes a card-delivering member 310, a driving member 320 for driving the card-delivering member 310 to rotate, and a card-delivering gear 330 disposed at one end of the card-delivering member 310 and rotating with the card-delivering member 310. The card-delivering mechanism 200 includes a card-delivering member 210 and a card-delivering gear 220 disposed at one end of the card-delivering member 210. The rotational speed of the card-delivering member 210 is lower than that of the card-delivering member 310. The distance between the card-delivering member 210 and the card-delivering member 310 is less than the length of a card, allowing cards to be delivered more smoothly through the card-delivering member 210 and the card-delivering member 310.

[0062] Reference Figure 7-10 A gear set 500 for transmitting and cutting off power is provided between the card dealing gear 330 and the card feeding gear 220. In the gear set 500, at least one gear can float to disengage the gear set 500, thereby cutting off the power transmission between the card dealing gear 330 and the card feeding gear 220.

[0063] The driving member 320 drives the card dealing member 310 to rotate, and the card dealing gear 330 drives the card feeding gear 220 through the gear set 500, thereby driving the card feeding member 210 to rotate, and the cards located in the card bin 110 are transported. When a card contacts the card feeding member 210 and the card dealing member 310 at the same time, the card moves faster under the drive of the card dealing member 310, and the trailing edge of the card applies force to the card feeding member 210, causing the rotation speed of the card feeding member 210 and the card feeding gear 220 to increase. At this time, at least one gear in the gear set 500 floats and disengages from the gear set 500, thereby cutting off the power transmission between the card dealing gear 330 and the card feeding gear 220. The clever use of the gear floating scheme ensures the working stability of the card dealing member 310 and the card feeding member 210, and enables the card feeding member 210 to have a considerable rotation speed even without power input, thereby reducing power loss, improving the operating efficiency and smoothness of the card dealing machine, and significantly reducing costs compared to the use of one-way bearings.

[0064] Specifically, refer to Figure 7-10 The gear assembly 500 includes: a first gear 510 located between the dealing gear 330 and the card delivery gear 220, with its axis located below the axis of the dealing gear 330; and a second gear 520 located between the first gear 510 and the card delivery gear 220, with its axis located above the axis of the first gear 510 and capable of floating. When a card simultaneously contacts the card delivery member 210 and the dealing member 310, the second gear 520 floats upward and disengages from the first gear 510, thereby cutting off power transmission. When the card passes the card delivery member 210, the second gear 520 returns to its original position under the action of gravity. In other embodiments, the gear assembly 500 may also be provided with other multiple gears, such as three or more gears, such as two gears, but the gear assembly 500 adopts a downward floating mechanism to disengage power transmission, as long as the gears can float to achieve power cutoff.

[0065] In order to prevent the second gear 520 from deviating from the set position when floating and resetting, refer to Figure 7-10 The second gear 520 is mounted on the housing 100 via a rotating shaft 521. The housing 100 is provided with a travel hole 150 for the rotating shaft 521 to float. Due to the limitation of the travel hole 150, the motion trajectory of the second gear 520 will not change, thereby improving the stability of the gear set 500.

[0066] In some embodiments, reference Figure 6 and Figure 11 To prevent multiple cards from passing through the card delivery mechanism 300 simultaneously, potentially causing a card dealing error, a forward-tilted card separation slope 160 is provided on the bottom surface of the card delivery port 130. As a card enters the card delivery port 130, its front end strikes the separation slope 160, causing it to be separated and then slide along the separation slope 160 into the card delivery mechanism 300. Using the separation slope 160 for card separation is simpler, more practical, and less expensive than other card separation mechanisms.

[0067] The angle between the card-splitting slope 160 and the bottom surface of the card bin 110 is between 115° and 166°. Specifically, in this embodiment, the angle between the card-splitting slope 160 and the bottom surface of the card bin 110 is 146.8°. In other embodiments, the angle between the card-splitting slope 160 and the bottom surface of the card bin 110 can also be 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 166°, etc. Specifically, when using a card-splitting machine, the angle between the card-splitting slope 160 and the bottom surface of the card bin 110 is converted into the angle between the card-splitting slope 160 and the card-supporting plate 410.

[0068] On the basis of using the card splitting slope 160 to split the card once, refer to Figure 6 and Figure 11A roller 600 is also provided between the card-splitting ramp 160 and the card-dealing mechanism 300. The roller 600 is mounted within the housing 100. The upper end surface of the roller 600 is 0.05-0.4 cm higher than the bottom surface between the card-splitting ramp 160 and the card-dealing mechanism 300. As a card passes through the roller 600, the front end of the card contacts the roller 600, causing a secondary card splitting. The card then slides along the roller 600 and enters the card-dealing mechanism 300. The placement of the roller 600 between the card-splitting ramp 160 and the card-dealing mechanism 300 not only enables secondary card splitting and improves the card-splitting effect, but also effectively reduces wear on the bottom surface between the card-delivery port 130 and the card-dealing mechanism 300. While the housing 100 of the card-dealing machine is typically made of plastic, the roller 600 is typically made of a more wear-resistant material, such as carbon structural steel. As the cards pass through the roller 600, they are lifted by the roller 600, significantly reducing friction between the cards and the housing 100. In other embodiments, the upper end surface of the roller 600 is 0.2 cm higher than the bottom surface between the card-scoring slope 160 and the card-delivering mechanism 300. In other embodiments, the upper end surface of the roller 600 can be 0.05 cm, 0.08 cm, 0.1 cm, 0.15 cm, 0.23 cm, 0.25 cm, 0.3 cm, 0.35 cm, 0.4 cm, etc. higher than the bottom surface between the card-scoring slope 160 and the card-delivering mechanism 300.

[0069] In order to make the roller 600 not too protruding and to better install the roller 600, refer to Figure 6 An arc-shaped groove 170 is further provided between the card-splitting slope 160 and the card-delivering mechanism 300 , and the roller 600 is placed in the arc-shaped groove 170 , and the upper end surface of the roller 600 protrudes from the arc-shaped groove 170 .

[0070] It is also feasible to not provide the card-splitting slope 160 and only provide the roller 600 between the card-delivering port 130 and the card-delivering mechanism 300, which can also achieve the card-splitting effect and reduce wear on the housing 100. The upper end surface of the roller 600 is 0.05-0.4 cm higher than the bottom surface between the card-delivering port 130 and the card-delivering mechanism 300.

[0071] In some embodiments, reference Figure 8 and Figure 11 When the upper card delivery machine solution is adopted, the card delivery component 210 includes: a first card delivery shaft 211, a first card delivery roller 212, a second card delivery shaft 213, a second card delivery roller 214, and a card delivery transmission assembly 215. The first card delivery shaft 211 is fixedly connected to the card delivery gear 220; the first card delivery roller 212 is fixed to the first card delivery shaft 211; the second card delivery shaft 213 is parallel to the first card delivery shaft 211; the second card delivery roller 214 is fixed to the second card delivery shaft 213; and the card delivery transmission assembly 215 is disposed between the first card delivery shaft 211 and the second card delivery shaft 213, and is used to drive the second card delivery shaft 213 to rotate via the first card delivery shaft 211.

[0072] The first card feeding shaft 211 and the second card feeding shaft 213 are parallel to each other, and the plane where the first card feeding shaft 211 and the second card feeding shaft 213 are located is parallel to the plane where the card holding plate 410 is located, so that when the cards on the card holding plate 410 are pressed upward by the card holding elastic member 420, the cards can stably contact the first card feeding roller 212 and the second card feeding roller 214 at the same time, thereby achieving a good card dealing effect.

[0073] In one embodiment, the first card delivery roller 212 and the second card delivery roller 214 are staggered in left and right directions, so that the first card delivery roller 212 and the second card delivery roller 214 act on a portion of the left and right width directions of the cards respectively. When facing some curved cards, the cards can also be driven by the contact card to deal the cards, achieving a good deal effect, avoiding the cards affecting the smoothness of dealing the cards, and improving the user experience of the card dealing machine. In the present embodiment, the second card delivery roller 214 is arranged in the middle of the card delivery port 130 rear side. When facing curved cards, it can also better contact the middle part of the cards to achieve a good deal effect. The first card delivery roller 212 is provided with two, respectively located on the left and right sides of the second card delivery roller 214, to rub the left and right sides of the contact card to deal the cards, so that the force balance of the card dealing in the left and right directions is achieved, avoiding the force imbalance that causes the dealing of the cards to be stuck or damage the cards, and improving the user experience of the card dealing machine.

[0074] In this embodiment, the driving member 320 of the card dealing mechanism 300 drives the rotation of the card dealing member 310 and the two card feeding rollers, without the need for an additional motor, effectively reducing costs and saving space.

[0075] In some embodiments, reference Figure 2 A card pressing ridge 411 is provided on the card holding plate 410 extending along the front-to-back direction. There are two card pressing ridges 411, which are symmetrically arranged on the left and right sides of the card holding plate 410, so that the playing cards on the card holding plate 410 can better contact the card feeding mechanism 200, thereby achieving a good card dealing effect.

[0076] In some embodiments, reference Figure 4 、 Figure 7 、 Figure 11 and Figure 12 Two sliding slots 180 extend vertically along the left and right side walls of the card compartment 110, each housing a sliding rod 430. A sliding member 412 extends toward the card holding plate 410, which fits over the sliding rods 430, enabling the card holding plate 410 to slide smoothly up and down within the card compartment 110. A card holding elastic member 420, configured as a spring, fits over the sliding rods 430 and is located between the sliding member 412 and the bottom of the sliding slots 180. The arrangement of four sliding slots 180 and four sliding rods 430 ensures stable vertical movement of the card holding plate 410.

[0077] In some embodiments, reference Figure 5 、 Figure 7 and Figure 8 The driving element 320 of the card dealing mechanism 300 is a motor. The card dealing component 310 comprises a card dealing shaft 311, a card dealing wheel 312, a card dealing transmission assembly 313, and an elastic card pressing assembly 314. The card dealing shaft 311 is fixedly connected to the card dealing gear 330; the card dealing wheel 312 is fixedly mounted on the card dealing shaft 311; the card dealing transmission assembly 313 transmits motor power to the card dealing shaft 311; and the elastic card pressing assembly 314 is located above the card dealing wheel 312. The elastic card pressing assembly 314 presses the cards against the card dealing wheel 312, ensuring good contact between the cards and accelerating their delivery, achieving optimal card dealing results.

[0078] In some embodiments, reference Figure 1 , further comprising a rotating base 700, which is disposed at the bottom of the housing 100. The rotating base 700 can rotate relative to the housing 100, thereby enabling the card dealing machine to deal cards in different directions.

[0079] Specifically, refer to Figure 13 The housing 100 is provided with a rotating motor 710 whose output shaft extends out of the bottom surface of the housing 100. The rotating base 700 is provided with a first rotating disk 720 that is power-connected to the output shaft of the rotating motor 710. A second rotating disk 730 is also provided, which is fixed to the center of the rotating base 700 and meshes with the first rotating disk 720. A bearing is provided between the axis of the second rotating disk 730 and the underside of the rotating base 700. When placed on a desktop for use, the second rotating disk 730 and the rotating base 700 remain stationary. Driven by the rotating motor 710, the first rotating disk 720 rotates on its own and rotates around the second rotating disk 730, thereby driving the housing 100 to rotate relative to the rotating base 700, achieving rotating card dealing.

[0080] In addition, a plurality of spaced-apart shielding sheets 721 are provided on the circumferential side of the first rotating disk 720, and a sensor 740 for sensing the shielding sheets 721 or sensing the gaps between the shielding sheets 721 is fixedly provided on the bottom surface of the shell 100. The position of the shielding sheets 721 is staggered with the second rotating disk 730 so as not to interfere. The sensor 740 cooperates with the shielding sheets 721 to locate the card dealing direction of the shell 100. Specifically in this embodiment, six shielding sheets 721 are provided, and are equidistantly distributed on the circumferential side of the first rotating disk 720. In other embodiments, other numbers of shielding sheets 721 may also be provided. Specifically in this embodiment, the sensor 740 is a photoelectric sensor.
