[0011] Optionally, the card-splitting mechanism further includes: an upper card component disposed on the side of the first card-splitting guide near the card-feeding opening and above the card-feeding opening, and a lower card component disposed below the card-feeding opening and corresponding to the upper card component.

[0012] Optionally, the scoring component includes: a frame and a scoring roller disposed on the front side of the frame and capable of rolling along the dealing direction; the front end of the frame is rotatably connected to the housing, and an elastic element is disposed between the upper surface of the frame and the housing near the rear end, the elastic element pressing the rear end of the frame toward the lower scoring component, thereby driving the scoring roller to press down onto the upper side of the lower scoring component.

[0013] Optionally, the card-distributing component includes a second card-distributing roller disposed below the card-distributing opening and capable of rolling along the card-distributing direction.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. In this utility model, the card-splitting mechanism includes: a first card-splitting guide disposed on the upper side of the card-feeding port, and a second card-splitting guide disposed on the lower side of the card-feeding port. The first card-splitting guide has a card-splitting protrusion corresponding to the second card-splitting guide on the side facing the second card-splitting guide. The second card-splitting guide cooperates with the card-splitting protrusion and the first card-splitting guide to separate multiple cards entering the card-feeding port, so that the cards pass through the card-splitting mechanism one by one. Furthermore, the second card-splitting guide first cooperates with the card-splitting protrusion to squeeze and deform the cards, thereby creating gaps between the multiple cards that are stuck together and separating them. Subsequently, the first card-splitting guide and the second card-splitting guide cooperate to further enhance the degree of separation of the multiple cards, thereby achieving a good card-splitting effect.

[0015] 2. In this utility model, the card-splitting mechanism further includes: an upper card-splitting component disposed on the rear side of the card-splitting guide (the side closest to the card compartment) above the card-feeding port, and a lower card-splitting component disposed below the card-feeding port, corresponding to the upper card-splitting component. The upper and lower card-splitting components cooperate with each other to perform a card-splitting operation before the cards reach the card-splitting guide. Then, a second card-splitting operation is achieved through the first card-splitting guide, the second card-splitting guide, and the card-splitting protrusion. The two card-splitting operations significantly reduce the possibility of cards sticking together during distribution, ensuring good card-distribution effect and accurate card quantity. The two-stage card-splitting operation also avoids the problem of excessive card-splitting that is stuck together at once, which would make the cards difficult to deform and unable to be separated. Splitting the card-splitting operation into two stages also improves the smoothness of card-splitting and enhances the user experience of the card-distributing machine. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0021] This embodiment relates to a highly efficient card dealing machine, such as... Figure 1-11 As shown, it includes: a housing 100, a card feeding mechanism 200, a card separating mechanism 300, and a card dealing mechanism 400. For ease of description and understanding, the direction in which the cards are dealt is referred to as the front side, and the opposite direction as the rear side.

[0022] The housing 100 has a card holder 110 for accommodating playing cards, a card delivery port 120 located at the bottom front of the card holder 110, and a card dispensing port 130 located at the front of the housing 100 and corresponding to the card delivery port 120. Inside the housing 100, between the card delivery port 120 and the card dispensing port 130, a card dispensing channel 140 is formed connecting the card holder 110 and the outside of the housing 100. Playing cards are placed into the card holder 110 through the card delivery port 120 and then dispensed from the card dispensing port 130.

[0023] A card feeding mechanism 200 is located at the bottom of the card storage 110 and is used to deliver the cards from the card storage 110 to the card feeding port 120. A card splitting mechanism 300 includes: a first card splitting guide 310 located on the upper side of the card feeding port 120; a second card splitting guide 320 located on the lower side of the card feeding port 120; the first card splitting guide 310 having a card splitting protrusion corresponding to the second card splitting guide 320 on its side facing the second card splitting guide 320; the second card splitting guide 320 cooperating with the card splitting protrusion and the first card splitting guide 310 to separate the multiple cards entering the card feeding port 120, so that... The cards pass through the card-splitting mechanism 300 one by one. Further, the second card-splitting guide 320 first cooperates with the card-splitting protrusion to squeeze and deform the cards, thereby creating gaps and separating the cards that are stuck together. Then, the first card-splitting guide 310 and the second card-splitting guide 320 cooperate to further enhance the separation of the cards, thus achieving a good card-splitting effect. The card-dispensing mechanism 400 is located between the card-splitting mechanism 300 and the card-feeding port 120, and is used to dispense the cards that have passed through the card-splitting mechanism 300 from the card-dispensing port 130. In this embodiment, only one card-splitting mechanism 300 is provided, positioned between the card delivery port 120 and the card dealing port 130. Located in the middle of the card delivery port 120, the card-splitting mechanism 300 performs card-splitting and card-rubbing operations. The second card-splitting guide 320, in conjunction with the first card-splitting guide 310 and the card-splitting protrusion, can compress the cards, making it easier for the cards to deform and creating gaps between multiple cards, thus achieving a good card-splitting effect. Simultaneously, the card-splitting mechanism 300 can also split narrower cards, improving the compatibility and smoothness of the card dealing machine. Of course, in other embodiments, the card-splitting mechanism 300 can be located at other positions within the card delivery port 120, or multiple sets can be provided.

[0024] Specifically, in this embodiment, the first card-splitting guide includes: a first guide slope 312 facing the dealing direction and inclined downwards; the card-splitting protrusion is disposed on the first guide slope 312; and the card-splitting protrusion 311 is provided with a second guide slope 313 facing the dealing direction and inclined downwards. Cards entering the card delivery port 120 from the card holder 110 will first impact the second guide slope 313 at their front end. The second guide slope 313 will guide the card to the bottom of the card-splitting protrusion and, in conjunction with the second card-splitting guide 320, compress the card, creating gaps between multiple cards. Subsequently, the front end of the card collides with the first guide slope 312, which guides the card to the bottom of the first card-splitting guide 310. At this point, the top of the front end of the card contacts the bottom of the first card-splitting guide 310, and the bottom of the middle of the card is compressed by the card-splitting protrusion 311 and the second card-splitting guide 320, thus forming a multi-part simultaneous compression of the card, achieving a good card-splitting effect.

[0025] As a preferred embodiment, the angle between the first guide slope 312 and the second guide slope 313 and the bottom surface of the card storage 110 is 30 degrees, so that the first guide slope 312 and the second guide slope 313 can effectively guide and distribute the cards. Of course, in other embodiments, the angle between the first guide slope 312 and the second guide slope 313 and the bottom surface of the card storage 110 can also be set to 20 degrees, 25 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees, etc.

[0026] As a preferred embodiment, the first card-splitting guide 310 further includes a guide roller 314 rotatably mounted on the front side of the first guide slope 312, with its lower surface lower than the lowest end of the first guide slope. The guide roller 314 guides the cards separated by the first card-splitting guide 310, allowing the cards to pass smoothly through the card-splitting mechanism 300, reducing friction between the cards and the mechanism, effectively improving card-splitting efficiency and smoothness, while also reducing wear on the cards and lowering the noise of the card-dealing machine. In this embodiment, two sets of guide rollers 314 are provided, respectively located on the left and right sides of the first guide slope, enabling better contact with the cards and improving the smoothness of card-splitting.

[0027] In this embodiment, the second card-separating guide 320 includes a plurality of coaxially arranged first lower card-separating rollers 321. The first card-separating guide 310 includes card-separating protrusions in a number corresponding to the number of the first lower card-separating rollers 321. The top of the first lower card-separating rollers 321 is higher than the bottom of the first guide slope. The plurality of coaxially arranged first lower card-separating rollers 321 and the corresponding number of card-separating protrusions form a stable multi-point engagement, so that the card body can be evenly supported and effectively separated when passing through the card-separating area. The top of the first lower card-separating rollers 321 is higher than the bottom of the second guide slope 313, which allows the card body to bend when squeezed by the first card-separating guide 310, the second card-separating guide 320, and the card-separating protrusions, thereby improving the card-separating effect.

[0028] In this embodiment, three first lower card-separating rollers 321 are provided, and two card-separating protrusions 311 are provided and are staggered with the first lower card-separating rollers 321. This allows the cards to be subjected to alternating action from the first lower card-separating rollers 321 and the card-separating protrusions 311 at different positions when passing through the card-separating mechanism 300. This breaks the adsorption force and static friction between adjacent cards multiple times, achieving a more thorough separation effect. The staggered arrangement avoids all separation forces being concentrated on the same contact line, reducing compression and wear on a single position. At the same time, it forms an interlaced separation path, making the cards more evenly stressed and running more smoothly.

[0029] In this embodiment, the card-splitting mechanism 300 further includes: an upper card-splitting component 330 disposed on the rear side of the card-splitting guide (the side near the card compartment 110) above the card-feeding port 120, and a lower card-splitting component 340 disposed below the card-feeding port 120 and corresponding to the upper card-splitting component 330. The upper card-splitting component 330 and the lower card-splitting component 340 cooperate with each other to perform a card-splitting operation before the cards reach the card-splitting guide. Then, a second card-splitting operation is completed through the first card-splitting guide 310, the second card-splitting guide 320, and the card-splitting protrusion. The two card-splitting operations significantly reduce the possibility of cards sticking together and ensure good card-splitting effect and accurate card-splitting quantity. Splitting the card-splitting operation into two operations also improves the smoothness of card-splitting and enhances the user experience of the card-splitting machine.

[0030] In this embodiment, the card-distributing component 340 includes a second card-distributing roller 334 disposed below the card-feeding port 120 and capable of rolling along the card-distributing direction. During the operation of the card-distributing machine, the second card-distributing roller 334 can rotate along the card-distributing direction, effectively reducing the friction between the card body and the card-distributing component 340, making the card body pass through the card-distributing component 340 more smoothly, and ensuring good card-distribution and card-distribution effects. As a preferred embodiment, the card-distributing component 340 further includes a card-distributing drive device 700, which includes a gear set 701 and a drive motor 702. The card-distributing drive device 700 is poweredly connected to the second card-distributing roller 334 to drive the second card-distributing roller 334 to rotate, so that the second card-distributing roller 334 can drive the card body to move, allowing the card body to enter the card-feeding port 120 more smoothly and pass through the card-distributing mechanism 300, improving the card-distributing efficiency of the card-distributing mechanism 300, and ensuring the smooth operation of the card-distributing machine.

[0031] As a preferred embodiment, the card-adding component 330 includes: a frame 331 and a card-adding roller 332 disposed on the front side of the frame 331 and capable of rolling along the card-dealing direction. The front end of the frame 331 is rotatably connected to the housing 100. An elastic element 333 is disposed between the upper surface of the frame 331 and the housing 100 near the rear end. The elastic element 333 presses the rear end of the frame 331 towards the card-adding component 340, thereby driving the card-adding roller 332 to press down onto the upper side of the card-adding component 340. The card-adding component 330 can accommodate cards of different thicknesses. During the card-dealing process, the card-adding roller 332 can move up and down according to the thickness of the card to allow cards of different thicknesses to pass through, eliminating the need for adjustment based on the card thickness, making it more convenient and worry-free. The frame 331 is rotatably connected to the housing 100 via a rotating shaft 340.

[0032] The card-spreading component 330 and the first card-spreading guide component 310 are not designed as a single unit. When the frame 331 moves up and down, it will not move the first card-spreading guide component 310, ensuring the stability of the position and direction of the first card-spreading guide component 310 and achieving a good card-spreading effect. Preferably, the first card-spreading guide component 310 is fixed to the housing 100 on the upper side of the card-feeding port 120. A groove is provided between the first card-spreading guide component 310 and the housing 100 for the frame 331 to rotate and connect, which reduces the distance between the first card-spreading guide components 310, makes the inside of the card-distributing channel 140 more compact, and optimizes the size of the card-distributing machine.

[0033] When the second scoring roller 334 is powered, the upper scoring roller 332 can press the cards towards the second scoring roller 334, increasing the friction between the cards and the second scoring roller 334. This allows the cards to be better driven by the second scoring roller 334 and smoothly enter the card delivery slot 120, achieving a good card distribution and dealing effect. Furthermore, two sets of upper scoring rollers 332 and second scoring rollers 334 are provided correspondingly.

[0034] In this embodiment, a card-dealing sensor 500 is installed at the card-dealing port 130 to detect the playing cards passing through the card-splitting mechanism 300, such as the number of cards and the speed, to achieve accurate card dealing. By detecting the speed of the cards, the power of the card-dealing mechanism 400 can be adjusted to change the distance at which the cards are dealt, achieving a good card dealing effect. As a preferred embodiment, the card dealing machine also includes a rotating base 600, which is located at the bottom of the housing 100. The rotating base 600 can rotate relative to the housing 100, allowing the card dealing machine to deal cards in different directions, achieving good usage results.

[0035] In this embodiment, the card dealing mechanism 400 includes a card dealing roller 410 disposed on the upper side of the card dealing channel 140. The rotation of the card dealing roller 410 drives the cards to be issued from the card dealing opening 130. As a preferred embodiment, both the second lower card-splitting roller 334 and the card dealing roller 410 provide power for issuing the cards by rubbing against the cards. The surfaces need to rub against the cards, increasing the contact area to achieve better card splitting and dealing effects. The second lower card-splitting roller and the card dealing roller 410 are respectively disposed on the upper and lower sides of the card dealing channel 140, staggered to avoid mutual interference between the two rollers and to optimize the internal space of the card dealing channel 140.

[0036] As a preferred embodiment, a card-pressing component 420 corresponding to the card-dealing roller 410 is provided on the lower side of the card-dealing channel 140. The card-pressing component 420 presses the cards in the card-dealing channel 140 against the card-dealing roller 410, allowing the cards to make better contact with the card-dealing roller 410, thereby increasing the friction between the cards and the card-dealing roller 410, ensuring smooth card dealing and achieving a good card-dealing effect. The volume of the card-dealing roller 410 is larger than the volume of the card-pressing component 420, resulting in a larger contact area between the card-dealing roller 410 and the card, increasing the friction between the cards and the card-dealing roller 410, and achieving a good card-dealing effect. The cards can be selected as playing cards.

[0037] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
