Description

Technical Field

[0001] The utility model relates to the field of entertainment products, in particular to a card dealing machine. Background Art

[0002] A card dealing machine is an entertainment device used to automatically deal playing cards, such as playing cards. It houses a card compartment within its housing for storing the cards. A card entry opening is located at the bottom of the compartment, and a limit mechanism is installed at the entry opening to restrict entry of only one card at a time. Existing limit mechanisms include upper and lower blocks. The spacing between the blocks is greater than the thickness of a single card and less than the thickness of two cards, ensuring that only one card can pass through at a time. However, in actual use, due to the uncertainty of card thickness, this can result in cards not being able to pass through or two cards being allowed to pass through simultaneously, impacting the user experience. Utility Model Content

[0003] The purpose of the utility model is to provide a card dealing machine, which can effectively solve the problem that the limiting mechanism of the existing card dealing machines cannot automatically adapt to playing cards of different thicknesses.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] A card dealing machine comprises a card bin for storing playing cards, a card discharging passage, and a card feeding mechanism for pushing playing cards into the card discharging passage, wherein the card discharging passage has a card inlet connected to the card bin. The card dealing machine also comprises a card adjusting mechanism arranged at the card inlet for limiting the number of playing cards pushed into the card discharging passage, wherein the card adjusting mechanism comprises an upper card rubbing block, a lower card rubbing block, and a card adjusting cavity for accommodating the lower card rubbing block, wherein a slider supporting the lower card rubbing block is provided in the card adjusting cavity, and the slider is pressed by the lower card rubbing block to generate relative displacement and change the support height of the lower card rubbing block, thereby adjusting the distance between the upper card rubbing block and the lower card rubbing block.

[0006] In the above-mentioned card dealing machine, the slider is arranged in the card mixing cavity for sliding in a direction parallel to the direction in which the playing cards enter the card discharging passage.

[0007] In the above-mentioned card dealing machine, an inclined support is formed between the slider and the lower card rubbing block, which is used to convert the compressive force applied to the lower card rubbing block into a force that pushes the slider to move.

[0008] In the above-mentioned card dealing machine, the upper end of the sliding block and the lower end of the lower card rubbing block are both provided with mutually abutting pushing inclined surfaces to form inclined surface supports.

[0009] In the above-mentioned card dealing machine, the card mixing cavity is provided with a guide hole communicated with the card entry port, and the lower card rubbing block is slidably arranged in the guide hole.

[0010] In the above-mentioned card dealing machine, a pre-tightening component is provided in the card adjusting cavity, and the pre-tightening component provides a pre-tightening force to the slider, so that the slider maintains a lifting tendency toward the lower card rubbing block.

[0011] In the above-mentioned card dealing machine, the pre-tightening assembly includes an elastic pre-tightening member, a movable adjusting member and a movable adjusting member. The elastic pre-tightening member is pre-tightened between the slider and the wall of the card mixing cavity. The movable adjusting member abuts against the slider. The movable adjusting member drives the movable adjusting member to move in the opposite direction of the pre-tightening force to push the slider to pre-tighten the elastic pre-tightening member.

[0012] In the above-mentioned card dealing machine, a sliding hole is formed on the sliding block, and the movable adjustment member passes through the sliding hole and is slidably engaged with the sliding hole.

[0013] In the above-mentioned card dealing machine, the movable adjusting member is threadedly connected to the movable adjusting member, and the movable adjusting member is non-rotatably arranged in the card adjusting cavity.

[0014] In the above-mentioned card dealing machine, a limiting hole is further provided on the slider, and the movable adjustment member is at least partially located in the limiting hole. The inner side wall of the limiting hole cooperates with the stopper of the peripheral wall of the movable adjustment member to limit the rotation of the movable adjustment member; or, the peripheral wall of the movable adjustment member contacts the plane of the cavity wall of the card adjusting cavity to limit the rotation of the movable adjustment member.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] The slider is pressed by the lower card block, causing relative displacement and changing the support height of the lower card block to adjust the distance between the upper and lower card blocks, thereby solving the current problem that the distance between the upper and lower card blocks cannot automatically adapt to playing cards of different thicknesses. A card adjustment mechanism is provided at the card entry to control the number of playing cards entering the card exit channel from the card entry. The card adjustment mechanism uses the distance between the upper and lower card blocks to adjust the amount of playing cards entering the card exit channel. A slider is provided in the card adjustment chamber to support the lower card block. When the thickness of the playing cards is too thick for a single card to pass between the upper and lower card blocks, the playing cards will exert downward pressure on the lower card block. The pressure on the lower card block pushes the slider to move, thereby changing the support height of the slider on the lower card block. In other words, the height of the lower card block is reduced, thereby increasing the gap between the lower and upper card blocks, allowing a single playing card to pass through, thereby achieving automatic adaptation to playing cards of different thicknesses.

[0017] Furthermore, the slider is arranged in the card mixing chamber to slide parallel to the direction in which the playing cards enter the card outlet. Generally, playing cards enter the card outlet in a horizontal position. Setting the slider to slide parallel to the direction in which the playing cards enter the card outlet makes it easier to control the force applied to push the slider, thereby more accurately controlling the distance between the lower and upper card shuffling blocks.

[0018] Furthermore, an inclined support is formed between the slider and the lower card-steering block, which is used to convert the compressive force applied to the lower card-steering block into a force that pushes the slider to move. The inclined support makes it easy to calculate the amount of pressure required to push the slider, thereby easily controlling the force of the control slider to hinder the descent of the lower card-steering block. Only when the lower card-steering block is under a certain pressure can the slider be pushed to slide and lower its height.

[0019] Furthermore, the upper end of the slider and the lower end of the lower card rubbing block are both provided with mutually abutting inclined surfaces to form an inclined surface support. The upper end of the slider and the lower end of the lower card rubbing block are both provided with inclined surfaces to enable the slider and the lower card rubbing block to form surface contact, so that the movement of the lower card rubbing block is more stable when it sinks, and it is not easy to cause the angle of the playing cards entering the card outlet channel to change due to overturning.

[0020] Furthermore, the card adjustment cavity is provided with a guide hole communicated with the card entry port, and the lower card rubbing block is slidably arranged in the guide hole. The sliding direction of the lower card rubbing block is limited by the guide hole to prevent the lower card rubbing block from getting stuck when sliding.

[0021] Furthermore, a pre-tightening assembly is provided within the card-adjusting chamber, which provides a pre-tightening force to the slider, causing it to maintain a tendency to lift the lower card-steering block. The pre-tightening assembly allows the slider to maintain a tendency to lift the lower card-steering block, returning the lower card-steering block to its initial position after the playing cards have passed through it. Furthermore, the pre-tightening force ensures that the lower card-steering block will not move until it is subjected to sufficient pressure, thereby widening the gap between it and the upper card-steering block.

[0022] Furthermore, the pre-tightening assembly includes an elastic pre-tightening member, a movable adjusting member, and a movable adjusting member. The elastic pre-tightening member is pre-tightened between the slider and the wall of the card-adjusting cavity. The movable adjusting member abuts the slider, and the movable adjusting member drives the movable adjusting member to move in the direction opposite to the pre-tightening force, thereby pushing the slider to pre-tighten the elastic pre-tightening member. The pre-tightening force is provided by the elastic pre-tightening member disposed between the slider and the wall of the card-adjusting cavity, and the movable adjusting member cooperates with the movable adjusting member to push the slider to move, thereby adjusting the space of the elastic pre-tightening member to achieve the adjustment of the pre-tightening force.

[0023] Furthermore, the slider is provided with a sliding hole, and the movable adjustment member passes through the sliding hole and slides with the sliding hole. The sliding direction of the slider can be limited by the cooperation between the sliding hole and the movable adjustment member, and the slider can also provide support for the movable adjustment member.

[0024] Furthermore, the movable adjusting member is threadedly connected to the mobile adjusting member, and the mobile adjusting member is non-rotatably disposed in the card adjustment cavity. With the above structure, rotating the movable adjusting member can achieve the purpose of axially moving the mobile adjusting member, thereby conveniently achieving the purpose of driving the slider to move and adjust the preload force by rotating the movable adjusting member.

[0025] Furthermore, the slider is provided with a limit hole, and the movable adjustment member is at least partially located within the limit hole. The inner side wall of the limit hole cooperates with the peripheral wall stop of the movable adjustment member to limit the rotation of the movable adjustment member; or the peripheral wall of the movable adjustment member contacts the plane of the cavity wall of the card-adjusting cavity to limit the rotation of the movable adjustment member. There are two different structural forms for limiting the rotation of the movable adjustment member. One is to use the limit hole on the slider to cooperate with the peripheral wall stop of the movable limit member to maximize the contact area between the movable adjustment member and the slider. The other is to use the peripheral wall of the movable adjustment member to contact the plane of the cavity wall of the card-adjusting cavity to minimize affecting the structure of the slider. Both can achieve the purpose of limiting the rotation of the movable adjustment member. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] A card dealing machine includes a card bin 100 for storing playing cards, a card discharging passage 200, and a card feeding mechanism 300 for pushing playing cards into the card discharging passage 200. The card discharging passage 200 has a card inlet 210 connected to the card bin 100. The card dealing machine also includes a card adjusting mechanism 400 arranged at the card inlet 210 for limiting the number of playing cards pushed into the card discharging passage 200. The card adjusting mechanism 400 includes an upper card rubbing block 410, a lower card rubbing block 420, and a card adjusting cavity 430 for accommodating the lower card rubbing block 420. A slider 440 supporting the lower card rubbing block 420 is provided in the card adjusting cavity 430. The slider 440 is pressed by the lower card rubbing block 420 to generate relative displacement and change the support height of the lower card rubbing block 420 to adjust the distance between the upper card rubbing block 410 and the lower card rubbing block 420.

[0035] The slider 440 is pressed by the lower shuffling block 420 to produce relative displacement and change the support height of the lower shuffling block 420 to adjust the distance between the upper shuffling block 410 and the lower shuffling block 420, thereby solving the problem that the distance between the upper and lower shuffling blocks 420 cannot automatically adapt to playing cards of different thicknesses. The card adjusting mechanism 400 is provided at the card inlet 210 to control the number of playing cards entering the card outlet passage 200 from the card inlet 210. The card adjusting mechanism 400 uses the distance between the upper card rubbing block 410 and the lower card rubbing block 420 to adjust the number of playing cards entering the card outlet passage 200. A slider 440 is provided in the card adjusting cavity 430 to support the lower card rubbing block 420. When the thickness of the playing cards is too thick for a single card to pass between the upper card rubbing block 410 and the lower card rubbing block 420, the playing cards will generate downward pressure on the lower card rubbing block 420. After being pressed, the lower card rubbing block 420 will push the slider 440 to move, thereby changing the support height of the slider 440 on the lower card rubbing block 420, that is, lowering the height of the lower card rubbing block 420, thereby increasing the gap between the lower card rubbing block 420 and the upper card rubbing block 410, so that a single playing card can pass through, thereby achieving the purpose of automatically adapting to playing cards of different thicknesses.

[0036] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings.

[0039] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0040] See Figures 1 to 6 This is an embodiment of a card dealing machine of the present invention, which includes a shell, in which a card bin 100 for storing playing cards is formed, a card outlet channel 200 is provided on the front side of the shell corresponding to the bottom of the card bin 100, and the card outlet channel 200 has a card inlet 210 connected to the card bin 100, a card feeding mechanism 300 for pushing playing cards into the card outlet channel 200 is provided in the card bin 100, a card adjusting mechanism 400 for limiting the number of playing cards entering the card outlet channel 200 is provided at the card inlet 210, and a card ejecting mechanism 700 is provided in the card outlet channel 200 downstream of the card adjusting mechanism 400. Its working principle is that the playing cards are stacked and placed in the card bin 100, and the card feeding mechanism 300 pushes the playing cards on the bottom layer from the card entry 210 into the card exit passage 200. The card adjusting mechanism 400 located at the card entry 210 controls that only one playing card enters the card exit passage 200 at a time, and the playing cards entering the card exit passage 200 will be ejected out of the card exit passage 200 by the card ejecting mechanism 700.

[0041] The card adjustment mechanism 400 comprises an upper card rubbing block 410, a lower card rubbing block 420 and a card adjustment cavity 430 for accommodating the lower card rubbing block 420, the upper card rubbing block 410 is positioned over the lower card rubbing block 420, the spacing between the upper card rubbing block 410 and the lower card rubbing block 420 is controlled to be greater than a playing card thickness and less than two playing card thicknesses, thereby realizing that only one playing card can pass through at each time.But because the thickness of different playing cards is different, the spacing between the upper card rubbing block 410 and the lower card rubbing block 420 need to be dynamically adjusted.The position of the upper card rubbing block 410 is fixed in the present embodiment, and is introduced with the relative position of regulating the lower card rubbing block 420.

[0042] A slider 440 supporting the lower card rubbing block 420 is provided in the card adjustment cavity 430. The slider 440 is pressed by the lower card rubbing block 420 to produce relative displacement and change the support height of the lower card rubbing block 420 to adjust the distance between the upper card rubbing block 410 and the lower card rubbing block 420. That is, when the playing cards cannot pass between the upper and lower card rubbing blocks 410 and 420, as the card feeding mechanism 300 pushes the playing cards, the playing cards will generate a downward squeezing force on the lower card rubbing block 420. After the force reaches a certain strength, it will push the lower card rubbing block 420 to move downward and then push the slider 440 to be displaced. After the slider 440 is displaced, the support height of the lower card rubbing block 420 is reduced, thereby increasing the distance between the upper and lower card rubbing blocks 410 and 420. After reaching the height for a single playing card to pass through, since a single playing card can pass through, the downward pressure on the lower card rubbing block 420 will continue but will not increase. Therefore, the lower card rubbing block 420 will remain at this height, so that subsequent playing cards can pass through the card adjusting mechanism 400 one by one and enter the card output channel 200.

[0043] Further, after the lower card rubbing block 420 is oppressed, it will move downward. At this moment, the slider 440 is translated or tilted in the direction in which the playing cards enter the card-discharging passage 200 and is slidably arranged in the card-adjusting cavity 430. The motion direction of the slider 440 is perpendicular to the motion direction of the lower card rubbing block 420, so that the slider 440 has a certain obstruction to the motion of the lower card rubbing block 420. It is possible to control the displacement of the lower card rubbing block 420 after being oppressed by a large amount of force. Generally, the direction in which the playing cards enter the card-discharging passage 200 is horizontal, and the bottom surface of the card-adjusting cavity 430 is also horizontal. The bottom surface of the card-adjusting cavity 430 can be utilized to limit the sliding of the slider 440, thereby eliminating the need for an additional limiting mechanism, which is conducive to reducing overall cost.

[0044] Since the slider 440 needs to have a certain obstructive effect on the movement of the lower card rubbing block 420 after it is pressed, the slider 440 and the lower card rubbing block 420 can be supported by an inclined surface or other supporting methods such as an arc surface, as long as the lower card rubbing block 420 can generate a component force that pushes the slider 440 to slide after being subjected to downward pressure. However, since the direction and magnitude of the component force generated by the inclined surface support are always consistent, it is relatively easy to control the downward pressure required for the slider 440 to move and adjust the distance between the lower card rubbing block 420 and the upper card rubbing block 410. This embodiment will be described by taking the inclined surface support formed between the slider 440 and the lower card rubbing block 420 as an example.

[0045] To form an inclined plane support, it is only necessary to set the upper end of the slider 440 or the lower end of the lower card rubbing block 420 to a push inclined plane 450. By the inclination of the push inclined plane 450, the direction of the contact force between the two and the direction of movement of the slider 440 and the lower card rubbing block 420 are all at a certain angle, generating a component force that pushes the slider 440 to slide. Of course, it is best that the upper end of the slider 440 and the lower end of the lower card rubbing block 420 are both provided with a push inclined plane 450, and the inclination of the two push inclined planes 450 is equal, so that the lower card rubbing block 420 and the slider 440 form an inclined plane support, that is, the two are always in surface contact. Like this, when the lower card rubbing block 420 moves, the slider 440 will always maintain a relatively stable support, avoiding the situation where the lower card rubbing block 420 turns over during movement and gets stuck with the card adjustment cavity 430. The angle of the pushing inclined surface 450 is generally between 10° and 70°. If the angle is too small, the playing cards cannot generate enough downward pressure on the lower card rubbing block 420, and therefore cannot generate enough component force to push the slider 440 to slide. If the angle is too large, the contact area between the lower card rubbing block 420 and the slider 440 will be too small, and the slider 440 will not be able to stably support the lower card rubbing block 420, resulting in the lower card rubbing block 420 being unable to move stably, and the lower card rubbing block 420 is prone to flipping and getting stuck.

[0046] On the basis of the above embodiment, in order to allow the lower card rubbing block 420 to maintain a stable operating state after being pressurized, a guide hole 431 communicating with the card inlet 210 is provided in the card adjusting cavity 430, and the lower card rubbing block 420 is slidably arranged in the guide hole 431, and the guide hole 431 is used to limit the movement trajectory of the lower card rubbing block 420. Moreover, the lower card rubbing block 420 is slidably arranged, so that the entire top surface of the lower card rubbing block 420 is synchronously displaced by a similar distance, which will not change the angle at which the playing cards enter the card outlet channel 200, thereby avoiding the playing cards from getting stuck in the card outlet channel 200.

[0047] Although the above structure can automatically adjust the spacing between the lower card rubbing block 420 and the upper card rubbing block 410 to adapt to the changed playing cards when the playing cards are thicker, if the playing cards are replaced with relatively thinner playing cards, the wider spacing between the lower card rubbing block 420 and the upper card rubbing block 410 will not ensure that only one playing card passes through the card adjustment mechanism 400. To solve the above problem, a pre-tightening component is provided in the card adjustment chamber 430. The pre-tightening component provides a pre-tightening force to the slider, so that the slider 440 maintains a tendency to lift the lower card rubbing block 420. In other words, the pre-tightening force generated by the pre-tightening component acts on the slider 440, which will cause the lower card rubbing block 420 to have an upward movement tendency. When the pressure exerted by the playing cards on the lower card rubbing block 420 is removed, the slider 440 will push the lower card rubbing block 420 upward under the action of the pre-tightening component, narrowing the spacing between the lower card rubbing block 420 and the upper card rubbing block 410, allowing the lower card rubbing block 420 to return to its initial position. During the dealing process of the same stack of playing cards, the pre-tightening component can also dynamically adjust the distance between the lower shuffling block 420 and the upper shuffling block 410 according to the different pressures applied by the playing cards to the lower shuffling block 420, thereby ensuring that when the thickness of the same stack of playing cards changes, the playing cards can still only pass through the card adjusting mechanism 400 one by one.

[0048] The preload assembly includes an elastic preload member 500, typically a spring or spring. This embodiment uses a spring as an example. The elastic preload member 500 can be positioned between the slider 440 and the wall of the card mixing cavity 430 along the direction of motion of the slider 440. However, the preload force of the elastic preload member 500 is fixed and cannot be adjusted based on the pressure exerted on the lower card shuffling block 420 by different playing cards. Therefore, the preload assembly also includes an active adjusting member 600 and a movable adjusting member 610. The movable adjusting member 610 abuts against the slider 440. The active adjusting member 600 drives the movable adjusting member 610 to move in the opposite direction of the preload force, so as to push the slider 440 to preload the elastic preload member 500. That is, the active adjusting member 600 will drive the movable adjusting member 610 to move and then push the slider 440 to squeeze the space of the elastic preload member 500, thereby achieving the purpose of increasing the elastic preload force. If the elastic preload force needs to be reduced, the active adjusting member 600 is adjusted in the opposite direction. Under the action of the elastic preload member 500, the slider 440 is pushed to move, so that the space of the elastic preload member 500 becomes larger, and the elastic preload force becomes smaller.

[0049] There are many types of adjustment structures for the movable adjusting member 600. For example, the movable adjusting member 600 can be a pull rod. Pulling the movable adjusting member 610 drives the slider 440 to squeeze the elastic preload member 500, thereby increasing the preload force. Alternatively, loosening the pull rod allows the elastic preload member 500 to push the slider 440 to drive the movable adjusting member 610 to a suitable position, and then fixing the relative position of the pull rod to maintain the preload force of the elastic preload member 500, thereby reducing the preload force. The movable adjusting member 600 can also be a bolt. As long as it can drive the slider 440 to different initial positions, the distance between the elastic preload member 500 and the wall of the card-adjusting cavity 430 can be adjusted to allow the elastic preload member 500 to generate different preload forces. Since the movable adjusting member 600 is at least partially located within the card-adjusting cavity 430, the movable adjusting member 600 can be spaced apart from the slider 440 to avoid interfering with the movement of the slider 440. However, since the movable adjusting member 600 drives the movable adjusting member 610 to push the slider 440 to move, a sliding hole 443 can be provided in the slider 440, allowing the movable adjusting member 600 to pass through the sliding hole 443, thereby achieving a sliding connection between the movable adjusting member 600 and the slider 440. In this way, the movable adjusting member 600 will not interfere with the sliding of the slider 440. At the same time, the movable adjusting member 610 connected to the movable adjusting member 600 can obtain a larger contact area with the slider 440 as much as possible, and the force between the movable adjusting member 610 and the slider 440 will be relatively uniform. The sliding engagement with the movable adjusting member 600 through the sliding hole 443 also allows the slider 440 to support the movable adjusting member 600.

[0050] like Figure 4 As shown, due to the self-locking capability of the bolt, it can relatively easily fix its relative position. Therefore, this embodiment will use a bolt as an example for the movable adjusting member 600. The tail of the bolt passes through the wall of the card-adjusting cavity 430 and is rotatably connected thereto. The portion of the bolt's tail located outside the card-adjusting cavity 430 facilitates the adjustment bolt's rotation. The head of the bolt passes through the sliding hole 443 of the slider 440 and is threadedly connected to the wall of the card-adjusting cavity 430, allowing the slider 440 to slide axially along the bolt's axis, thereby securing the bolt. A nut can be mounted on the bolt to form a movable adjusting member 610. The movable adjusting member 610 and the elastic preload member 500 abut opposite ends of the slider 440. The elastic preload member 500 generates a preload force that pushes the slider 440 to the right. Rotating the bolt can drive the slider 440 to the left via the movable adjusting member 610, squeezing the elastic preload member 500 and increasing its preload force.

[0051] On the basis of the above embodiment, the movable adjusting member 610 can be fixedly connected to the active adjusting member 600, that is, the nut will rotate together with the bolt, and the end face of the nut will abut against the end face of the slider 440. Since the bolt is threadedly connected to the cavity wall of the card adjustment cavity 430, as the bolt rotates, the bolt will push the slider 440 together with the nut to move the space of the compressed elastic preload member 500. Alternatively, the movable adjusting member 610 is threadedly connected to the movable adjusting member 600. To prevent the nut from rotating with the bolt when the bolt is rotated, the nut's circumferential rotation needs to be limited. This can be achieved by providing a limiting hole 444 on the slider 440, allowing the nut to be at least partially located within the limiting hole 444. The inner sidewall of the limiting hole 444 cooperates with the nut's peripheral wall stop. For example, if the nut has a hexagonal cross-section, the limiting hole's cross-section can also be hexagonal, thereby limiting the nut's rotation. Alternatively, the nut's peripheral wall can be brought into contact with the plane of the cavity wall of the card-adjusting cavity 430, that is, one of the planes of the nut's peripheral wall contacts the bottom wall of the card-adjusting cavity 430, thereby also achieving the purpose of limiting the nut's rotation. In this way, when the bolt is rotated, the nut will move relative to the bolt along the bolt's axis, pushing the slider 440 to move.

[0052] like Figure 5 、 Figure 6 As shown, a guide groove 441 can also be provided on one of the top of the slider 440 and the bottom surface of the lower rubbing block 420, and the other can be provided with a guide block 421 that slides in the guide groove 441. In the present embodiment, the guide groove 441 is provided on the top surface of the slider 440, and the guide block 421 is provided on the bottom surface of the lower rubbing block 420, and the guide groove 441 is tilted along the top pushing inclined surface 450 direction of the slider 440 top surface, so that the interaction of the guide groove 441 and the guide block 421 can be utilized to limit the sliding direction of the lower rubbing block 420. Of course, the cooperation of the guide groove 441 and the guide block 421 adopted can also no longer use the structure of the inclined surface support, or can make the lifting of the lower rubbing block 420 more stable by using the inclined surface support together.

[0053] Furthermore, a blocking portion 442 is provided on the guide groove 441 for stopping the guide block 421 along the moving direction of the lower shuffling block 420. The blocking portion 442 will prevent the lower shuffling block 420 from separating from the slider 440. In this embodiment, the guide groove 441 will adopt a dovetail groove to form a guide groove 441 with a blocking portion 442, ensuring that the lower shuffling block 420 can always be close to the slider 440 when the lower shuffling block 420 rises or sinks.

[0054] Through the above structure, the slider 440 is used to support the lower card rubbing block 420, so that the lower card rubbing block 420 can dynamically adjust the gap between it and the upper card rubbing block 410 according to the thickness of the playing cards, so as to better adapt to a variety of playing cards of different specifications, and the lower card rubbing block 420 can be set to slide up and down to avoid the lower card rubbing block 420 from swinging, so that the lower card rubbing block 420 will not change the angle of the playing cards after passing through the card inlet 210, so that the playing cards can smoothly enter the card ejection mechanism 700, reducing the jamming of the playing cards.

[0055] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in this field within the scope of the present invention are included in the patent scope of the present invention.
