[0031] Please refer to Figures 1 to 6 This embodiment provides a card dealing machine, comprising a housing 100, a card feed wheel assembly 200, a drive device 300, a card dealing device 400, a control chip 500, and a battery 600. The housing 100 is configured with a card chamber 110, a card inlet 120, and a card outlet 130. The card chamber 110 is configured to accommodate at least one set of cards. The card chamber 110 is connected to the card inlet 120, allowing cards to enter the card dealing device 400 through the card inlet 120. The card outlet 130 is located outside the housing 100 relative to the card chamber 110 and is configured to deal cards. The card feed wheel assembly 200, the drive device 300, the control chip 500, and the battery 600 are all connected within the housing 100, and the card dealing device 400 is fixed between the card inlet 120 and the card outlet 130. Among them, the driving device 300, the control chip 500 and the battery 600 are electrically connected, and the driving device 300 is respectively connected to the card feeding wheel group 200, the card feeding wheel group and the card discharging wheel group of the card dealing device 400. The driving device 300 can drive the card feeding wheel group 200, the card feeding wheel group and the card discharging wheel group of the card dealing device 400 to rotate to deliver cards.

[0032] In this embodiment, the card feeding wheel assembly 200 includes a first card feeding wheel 210 and a second card feeding wheel 220 that are spaced apart. The first card feeding wheel 210 and the second card feeding wheel 220 are rotatably exposed at the bottom of the card chamber 110 and are configured to contact the cards in the card chamber 110 to drive the cards forward into the card inlet 120. The driving device 300 includes a motor 310 and a gear set 320. One of the gears in the gear set 320 is fixed to the output shaft of the motor 310. The gear set 320 is also coaxially fixed to the first card feeding wheel 210, the second card feeding wheel 220, and the card infeed wheel assembly and the card outfeed wheel assembly of the card dealing device 400 through a plurality of output gears. When the motor 310 is started, the gear set 320 drives the first card feeding wheel 210, the second card feeding wheel 220, and the card infeed wheel assembly and the card outfeed wheel assembly of the card dealing device 400 to rotate synchronously. It should be noted that both the card feed wheel assembly 200 and the drive device 300 utilize existing structures. Their specific structural configurations and operating principles are well known in the art and will not be described in detail here. In other embodiments of the present invention, the number and distribution of the card feed wheels within the card feed wheel assembly 200 can be adjusted as needed. Similarly, the number of teeth and transmission ratio of the gear assembly 320 can also be adjusted as needed.

[0033] The card dealing device 400 includes a mounting base 410 connected to the housing 100, as well as a card passing plate 420, a card feed wheel assembly 430, and a card discharge wheel assembly 440 connected to the mounting base 410. The mounting base 410 includes a first housing 411 and a second housing 412, each of which is fixedly connected. A gap 413 is formed between the first housing 411 and the second housing 412, connecting the card feed port 120 and the card discharge port 130. Cards can be transported through the gap 413 to the card discharge port 130 for delivery. In this embodiment, the first housing 411 is connected to the inner wall of the card chamber 110 and the two are arranged at an angle, so that the end of the card chamber 110 can extend downwardly to the card discharge port 130. This can facilitate the cards to maintain a tendency to slide obliquely into the gap 413, thereby improving the smoothness of card delivery. In other embodiments of the present invention, the first housing 411 and the inner wall of the card chamber 110 can be adjusted to a horizontal structure.

[0034] It will be appreciated that the first housing 411 is provided with a first connection port 4111, which allows the driving wheels of the card feed wheel assembly 430 and the card output wheel assembly 440 to be exposed within the gap 413. In this embodiment, the first housing 411 is further provided with a first protrusion 4112 and a second protrusion 4113. Both ends of the first protrusion 4112 and the second protrusion 4113 have inclined guide surfaces. The first protrusion 4112 is used to guide cards at the card feed port 120 to the card feed wheel assembly 430, and the second protrusion 4113 is used to guide cards at the card pass plate 420 to the card output port 130. In other embodiments of the present invention, the first housing 411 may not be provided with the first protrusion 4112 and / or the second protrusion 4113.

[0035] The second housing 412 includes an upper housing 4121 and a lower housing 4122, which are fixedly connected. The upper housing 4121 is provided with a second connection port 4123, which allows the driven wheels of the card input wheel assembly 430 and the card output wheel assembly 440 to be exposed in the gap 413. The upper housing 4121 is provided with a plurality of connection posts 4124 protruding from the side facing the lower housing 4122. The upper housing 4121 is fixedly connected to the lower housing 4122 via the connection posts 4124. For example, the lower housing 4122 can be fixed to the connection posts 4124 using screws, a snap-fit ​​structure, etc.

[0036] The card passing plate 420 is clamped and fixed between the first housing 411 and the second housing 412 and is arranged between the card input wheel assembly 430 and the card output wheel assembly 440. Accordingly, the first housing 411 and the second housing 412 are respectively provided with grooves 414 that match the external shape of the card passing plate 420, and the card passing plate 420 can be detachably inserted and fixed into the two grooves 414. In other words, the card passing plate 420 is detachably connected between the first housing 411 and the second housing 412. As a result, the card dealing device 400 can adapt to cards of different thicknesses, such as cards made of non-traditional materials such as carbon fiber and plastic, by replacing the card passing plate 420 with different card passing opening widths in the mounting seat 410. This can expand the scope of application of the card dealing device 400 and improve its applicability and practicality.

[0037] In this embodiment, the card-passing plate 420 is a metal piece manufactured by integral molding. Compared to the plastic card-passing plate 420, the metal card-passing plate 420 has the advantages of being easy to mold, being easily formed, and having a low manufacturing cost. Moreover, the integrally molded metal piece has the advantages of being highly rigid and not easily deformed, which can increase the structural stability of the card-dealing device to a certain extent. The card-passing plate 420 has a card-passing opening 421 corresponding to the gap 413. The inner wall of the card-passing opening 421 extends toward each other at the position of the card-feeding wheel assembly 430 and the card-discharging wheel assembly 440. A gap 424 is constructed between the first card-passing block 422 and the second card-passing block 423, allowing only one card to pass through. It is understood that the card-passing opening 421 can limit the number of cards that can be issued during a single card-dealing session, and the card-passing plate 420 can also ensure that each card can be fed into the card-discharging wheel assembly 440, thereby ensuring the stability and reliability of the card-discharging device 400. In other embodiments of the present invention, the card passing plate 420 may also be made of other materials in one piece or by splicing, such as plastic.

[0038] It should be noted that the first card passing block 422 and the second card passing block 423 are provided with a guiding slope 425 inclined from the outside to the inside relative to one side of the card feed wheel group 430, wherein the guiding slope of the first card passing block 422 and its end face are chamfered, so that the cards can enter the gap 424 stably and smoothly along the guiding slope 425.

[0039] The card-input wheel assembly 430 is used to clamp and deliver the cards entering the card-input port 120 to the card-passing port 421, and the card-discharging wheel assembly 440 is used to clamp and deliver the cards entering the card-passing port 421 to the card-discharging port 130. It is understood that the card-input wheel assembly 430 includes a first driving wheel 431 rotatably connected to the first housing 411 and a first driven wheel 432 rotatably connected to the second housing 412, and the first driving wheel 431 and the first driven wheel 432 are arranged relative to each other to clamp and transport the cards. The card-discharging wheel assembly 440 includes a second driving wheel 441 rotatably connected to the first housing 411 and a second driven wheel 442 rotatably connected to the second housing 412, and the second driving wheel 441 and the second driven wheel 442 are arranged relative to each other to clamp and transport the cards. It should be noted that the first driving wheel 431 and the second driving wheel 441 are partially exposed within the gap 413 through the first connecting port 4111, and the first driven wheel 432 and the second driven wheel 442 are partially exposed within the gap 413 through the second connecting port 4123. The first driving wheel 431 and the second driving wheel 441 are each coaxially fixed to one of the drive gears of the gear set 320, and are configured to rotate simultaneously by the drive of the gear set 320. The first driven wheel 432 and the second driven wheel 442 are each floatingly mounted on the second housing 412 via a limit plate 450. Each limit plate 450 is movably connected to the connecting column 4124 via an elastic member 460, and the limit plates 450 are correspondingly connected to the connecting shafts of the first driven wheel 432 and the second driven wheel 442. The elastic member 460 is used to push the first driven wheel 432 and the second driven wheel 442 to move toward the first driving wheel 431 and the second driving wheel 441 through the limiting plate 450 so as to clamp and transport the cards.

[0040] In this embodiment, the first driving wheel 431 is a D-shaped wheel comprising a flat surface and a curved surface connected end to end. It will be appreciated that the first driving wheel 431 is controlled by the drive device 300 to rotate continuously. During this process, a large gap is formed between its flat surface and the first driven wheel 432. Even cards with bent or deformed leading edges can easily enter between the first driving wheel 431 and the first driven wheel 432. Subsequently, the curved surface and the first driven wheel 432 compress the cards, allowing them to pass smoothly and evenly through the gap 424. This improves the success rate of the card feed wheel assembly 430 in conveying bent or deformed cards, reduces the probability of the card dealing device 400 becoming stuck or failing to deal cards, and further enhances the stability and reliability of the card dealing device 400. In other embodiments of the present invention, the first driving wheel 431 can also be configured as a cylindrical roller.

[0041] In this embodiment, the card dealing device 400 is further provided with a card-discharging sensing device 470. The card-discharging sensing device 470 includes a light emitter 471 and a light receiver 472 fixed relative to the first housing 411 and the second housing 412, and a light sensor 473 clamped between the first housing 411 and the second housing 412. The light emitter 471 and the light receiver 472 are disposed at the card-discharging port 130. The light sensor 473 is C-shaped and has a slot 4731 corresponding to the gap 413 for cards to pass through. The light sensors 473 are sequentially arranged along the line connecting the card inlet 120 to the card outlet 130. It is understood that the light emitter 471, light receiver 472, and light sensor 473 are used to detect when a card passes through the card outlet 130 and send information to the control chip 500. The control chip 500 controls the motor 310 to stop working or slow down its speed, increasing the interval between the delivery of two adjacent cards, thereby ensuring that the card delivery sensing device 470 can perform accurate detection, reducing the probability of counting errors, and improving the accuracy of card delivery. When a card is detected to have moved away from the card outlet 130, information is sent to the control chip 500, and the control chip 500 controls the motor 310 to operate normally. In other embodiments of the present invention, the card delivery device 400 may not be provided with the card delivery sensing device 470, and the card delivery sensing device 470 may also include only the light emitter 471 and light receiver 472 or the light sensor 473.

[0042] For clarity, certain features of the present invention described in the context of separate embodiments may be combined in a single embodiment. Furthermore, various features of the present invention described in the context of a single embodiment may also be used individually or in any suitable subcombination.
