[0002] Poker is a popular card game enjoyed by many. A poker game involves shuffling, arranging, and dealing the cards. During the dealing process, a card-lifting device pushes the cards onto the card-arranging machine table for the players to play. Before the cards are lifted onto the card-arranging machine table, a push-pull device pushes them onto a designated card-lifting plate. These different actions and driving requirements necessitate the use of separate driving mechanisms. Summary of the Invention

[0055] Preferably,

[0056] The card sorting machine includes a poker machine, a mahjong machine, or a dominoes machine.

[0057] The positive and progressive effects of this invention are as follows:

[0058] 1) This invention designs a single-machine intermittent selective drive mechanism, which is connected to both the sliding card pusher and the lifting rocker arm. At any given moment, this mechanism can either drive the sliding card pusher towards the card-raising compartment to push the cards from the receiving seat onto the card-raising plate, or drive the lifting rocker arm to rotate to push the card-raising plate in the card-raising compartment to a higher position or lower it to a lower position. In other words, this invention, through this single-machine intermittent selective drive mechanism, can sequentially drive the sliding card pusher to pull cards and drive the lifting rocker arm to raise and lower the playing cards on the card-raising plate, improving overall drive efficiency and saving drive costs.

[0059] 2) The present invention also designs a Z-shaped lifting rocker arm with a U-shaped groove. The end of the U-shaped groove is slidably locked below the lifting plate. On the one hand, the locking connection allows the lifting plate to rise and fall in real time following the rotation of the lifting rocker arm. On the other hand, the sliding locking through the U-shaped groove also allows the Z-shaped lifting rocker arm to rotate freely below the lifting plate and drive the lifting rocker arm to rise and fall.

[0072] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0073] It should be noted that in the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features, nor should they be construed as limiting the specific scope of protection of this invention.

[0074] like Figure 1 and Figure 2 As shown, the single-machine card-pulling and lifting mechanism for the card sorting machine of the present invention includes a card receiving base 10, a sliding card-pushing base 20 disposed on one side of the card receiving base 10 and movable back and forth within the card receiving base 10, a card lifting mechanism 30 mounted on the other side of the card receiving base 10, and a single-machine intermittent selective drive mechanism 40. The lifting mechanism 30 includes a card lifting chamber 31, a card lifting plate 32 that can move up and down within the card lifting chamber 31, and a lifting rocker arm 33 that can be supported below the card lifting plate 32. The single-machine intermittent selective drive mechanism 40 can be connected to the sliding card-pushing base 20 and the lifting rocker arm 33 respectively, so that at a certain moment, the single-machine intermittent selective drive mechanism 40 only drives the sliding card-pushing base 33 to move towards the card lifting chamber 31 to push the cards on the card receiving base 10 onto the card lifting plate 31, or only drives the lifting rocker arm 33 to rotate to push the card lifting plate 32 in the card lifting chamber 31 to a high position or lower it to a low position.

[0075] Continue as Figure 2As shown, the card receiving base 10 has a wedge-shaped surface 11 that can mate with the lowered card-lifting plate 32. In this example, the wedge-shaped surface 11 is formed by the hypotenuses of two spaced-apart triangular plates, so the wedge-shaped surface 11 can be considered as a virtual inclined surface; in another example, the wedge-shaped surface 11 can also be formed by a single inclined flat plate (not shown). Playing cards arranged face-down from the shuffling tray can be directly fed onto the wedge-shaped surface 11 of the card receiving base 10 via the tray's outlet. Alternatively, playing cards arranged face-up from the shuffling tray can first be sent to the flipping mechanism via the tray's outlet to be flipped face-down before being sent onto the wedge-shaped surface 11 of the card receiving base 10. Continuing as... Figure 2 As shown, the highest edge of the wedge-shaped surface 11 is close to and slightly higher than the lower card-raising plate 32, making it easier to push the playing cards on the receiving seat 10 along the wedge-shaped surface 11 onto the lower card-raising plate 32. Furthermore, continuing as... Figure 2 As shown, a guide rail 12 is provided on the opposite sidewalls of the two wedge-shaped surfaces 11 for the sliding card pusher 20 to slide. That is, the sliding card pusher 20 slides back and forth along the guide rail 12, and continuously pushes the playing cards on the card receiving seat 10 along the wedge-shaped surface 11 to the card lifting plate 32 during the back and forth sliding process.

[0076] like Figure 3 and Figure 4 As shown, the sliding card pusher 20 has a sliding base 21, a sliding base reset member 22, and a pull rope 23. The sliding base 21 is located below the wedge-shaped surface 11 of the card receiving base 10, and the sliding base 21 has a card pusher 211 facing the card lifting plate 32 and a pulley 212 that can slide along the guide rail 12 of the card receiving base 10. The sliding base reset member 22, which is also a spring, has a fixed end and a moving end. The fixed end of the sliding base reset member 22 is fixedly connected to the card receiving base 10, and the moving end is fixedly connected to the sliding base 21, so as to reset the sliding base 21 that has moved to the card lifting plate 32 back to the initial position for the next card push. One end of the pull rope 23 is fixedly connected to the sliding base 21, and the other end can be driven by the single-machine intermittent selectable drive mechanism 40 to retract towards the card-raising mechanism 30. This allows the retracted pull rope 23 to move the sliding base 21 towards the card-raising mechanism 30, and further causes the entire sliding card pusher 20 to push the playing cards towards the card-raising plate 32 of the card-raising mechanism 30. This realizes the single-machine intermittent selectable drive mechanism 40 driving the push and pull of the playing cards. In addition, the single-machine intermittent selectable drive mechanism 40 can also be used to drive the raising and lowering of the playing cards.

[0077] Continue as Figures 3 to 6CAs shown, the lifting rocker arm 33 is a Z-shaped lifting rocker arm, comprising an arm body 331, an arm shaft 332, and a wide plate support head 333. The arm shaft 332 is rotatably mounted on one wall of the card-lifting chamber 31 and is vertically fixed to one end of the arm body 331, allowing the arm body 331 to rotate. The wide plate support head 333 is fixedly mounted on the other end of the arm body 331 to support the card-lifting plate 32 within the card-lifting chamber 31. The arm body 331 can rotate, driving the wide plate support head 333 to rotate, further supporting the card-lifting plate 32 as it rises and falls within the card-lifting chamber 31. Furthermore, the wide plate support head 333 has a wide support surface 333a supporting the card-lifting plate 32 when it is in a high position and a narrow support surface 333b supporting the card-lifting plate 32 when it is in a low position. The wide support surface 333a and the narrow support surface 333b are smoothly transitioned and adjacent to each other. Furthermore, a U-shaped groove 3331 is provided on the wide plate support head 333, and a limiting groove 321 along the rotation direction of the lifting rocker arm 33 is provided below the lifting plate 32. The U-shaped groove 3331 on the wide plate support head 333 can slide and be engaged in the limiting groove 321 below the lifting plate 32 along the length direction of the limiting groove 321 below the lifting plate 32. That is, during the process of the lifting rocker arm 33 rotating and driving the lifting plate 32 to descend from a high position to a low position, the wide plate support head 333 is first supported below the lifting plate 32 by the wide support surface 333a. As the arm body 331 rotates, the wide plate support head 333 also rotates, gradually rotating until the narrow support surface 333b replaces the wide support surface 333a to support the lifting plate 32. At the same time, during the rotation, the U-shaped groove 3331 on the wide plate support head 333 slides in the limiting groove 321. Continuing as shown in Figures 1 and 2, to ensure more stable rising and falling of the lifting plate 32 within the lifting chamber 31, several vertical guide protrusions and concave structures 311 are installed on the wall of the lifting chamber 31, while corresponding inlay protrusions and concave structures 322 are present around the periphery of the lifting plate 32. The inlay protrusions and concave structures 322 of the lifting plate 32 are slidably embedded into the vertical guide protrusions and concave structures 311 of the lifting chamber 31, allowing it to rise and fall within the lifting chamber 31. When the vertical guide protrusions and concave structures 311 are guide grooves, the inlay protrusions and concave structures 322 are inlay protrusions corresponding to the guide grooves; and when the vertical guide protrusions and concave structures 311 are guide ridges, the inlay protrusions and concave structures 322 are inlay grooves corresponding to the guide ridges. In addition, several reinforcing ribs are installed on the lower surface of the lifting plate 32 to enhance its strength.

[0078] Continue as Figures 3-5As shown, the single-machine intermittent selective drive mechanism 40 includes a first drive rod 41, a second drive rod 42, a first annular arc-shaped through groove 43 on the drive head at one end of the first drive rod 41, a second annular arc-shaped through groove 44 on the drive head at one end of the second drive rod 42, and a card-pulling and lifting drive mechanism 45. The first drive rod 41 and the second drive rod 42 are mounted side-by-side, with the second drive rod 42 mounted opposite to the outside of the first drive rod 41. One end of the first drive rod 41 has a flat drive head with the first annular arc-shaped through groove 43 extending throughout the entire thickness direction, and one end of the second drive rod 42 has a flat drive head with the second annular arc-shaped through groove 44 extending throughout the entire thickness direction. The first annular arc-shaped through groove 43 and the second annular arc-shaped through groove 44 are mounted with opposite protrusions. The card-pulling and lifting drive mechanism 45, also known as the motor, has a bearing 451 on its shaft that passes through both the first and second annular arc-shaped through grooves 43 and 44, respectively. This allows the bearing 451 to drive either the first or second annular arc-shaped through groove 43 to move when the shaft of the drive mechanism 45 rotates, thereby sequentially driving either the first or second drive rod 42. Specifically, when the bearing 451 drives the first annular arc-shaped through groove 43 and the first drive rod 41, the bearing 451 rotates along the second annular arc-shaped through groove 44 without driving the second drive rod 42; conversely, when the bearing 451 drives the second annular arc-shaped through groove 44 and the second drive rod 42, the bearing 451 rotates along the first annular arc-shaped through groove 43 without driving the first drive rod 41. Continuing as shown in the figure, a first gear set 411 is fixed to the rod body of the first drive rod 41, and a second gear set 421 is fixed to the rod body of the second drive rod 42. The first gear set 411 is driven to the lifting rocker arm 33, and the second gear set 421 is driven to the sliding push plate holder 20. Specifically, continuing as shown in the figure, the first gear set 411 has a first rack 4111 fixed to the rod body of the first drive rod 41 and an arm shaft gear 4112 meshing with the first rack 4111. The arm shaft gear 4112 is installed on the side end of the arm shaft 332 of the lifting rocker arm 33, so that the lifting rocker arm 33 can be driven to rotate by the first rack 4111 through the arm shaft gear 4112. The second gear set 421 has a second rack 4211 fixed to the rod body of the second drive rod 42 and a compound gear set 4212 meshing with the second rack 4211.The compound gear set 4212 includes a first pull rope gear 42121, a second pull rope gear 42122, a third pull rope gear 42123, and a winding wheel 42124. The first pull rope gear 42121 meshes with the second rack 4211, the second pull rope gear 42122 is coaxially connected with the first pull rope gear 42121, the third pull rope gear 42123 meshes with the second pull rope gear 42122, and the winding wheel 42124 is coaxially connected with the third pull rope gear 42123. The other end of the pull rope 23 is wound around the winding wheel 42124. That is, through the meshing and linkage of the above gears, the winding wheel 42124 can be rotated to tighten the pull rope 23, thereby using the pull rope 23 to drive the sliding push plate holder 20 at the other end to move. When the winding wheel 42124 is driven to rotate in the opposite direction, the other end of the pull rope 23 is unscrewed and pulled out from the winding wheel 42124 due to the action of the sliding plate reset piece 22 of the sliding push plate seat 20, i.e., the spring.

[0079] Continuing as shown in the figure, the single-machine intermittent selective drive mechanism 40 also includes a limiting rod 46, a first limiting block 47, and a second limiting block 48. The limiting rod 46 is fixedly mounted on two opposing wall panels extending outward from the card-lifting compartment 31, and is arranged parallel to the first drive rod 41 and the second drive rod 42. The first limiting block 47 and the second limiting block 48 are both slidably mounted on the limiting rod 46. Continuing as shown in the figure, the first rack 4111 is fixedly mounted on the middle section of the first drive rod 41, and the first limiting block 47 is fixed on the side of the first drive rod 41 or the first rack 4111. In this example, the first limiting block 47 is fixed on the side of the first rack 4111, and the first drive rod 41 is fixedly mounted inside the first limiting block 47, thus restricting the first drive rod 41 to move horizontally only along the limiting rod 46, and during horizontal movement, it can drive the fixed first rack 4111 and the first limiting block 47 to move accordingly. Simultaneously, the second drive rod 42, installed parallel to and adjacent to the first drive rod 41, also passes through the first rack 4111 or the first limiting block 47, and the middle section of the second drive rod 42 can slide freely within the first rack 4111 or the first limiting block 47. Furthermore, as shown in the figure, the second rack 4211 is fixedly installed at the lower part of the rear section of the second drive rod 42, and the second limiting block 48 is fixed to the side of the second drive rod 42 or the second rack 4211. In this example, the second limiting block 48 is fixed to the side of the second rack 4211. Similarly, the second drive rod 42 is also fixedly passed through the second limiting block 48, allowing the second drive rod 42 to move horizontally along the limiting rod 46 due to the second limiting block 48.

[0080] In general, the bearing 451 on the shaft of the card-pulling and lifting drive mechanism 45 is rotatably mounted in the first annular arc-shaped through groove 43 of the first drive rod 41 and the second annular arc-shaped through groove 44 of the second drive rod 42. During the rotation of the shaft, the first and second annular arc-shaped through grooves with opposite protrusions can intermittently and sequentially drive the first drive rod 41 and the second drive rod 42 to move. When the first drive rod 41 is driven to move, it can indirectly drive the lifting rocker arm 33 to move up and down, thereby driving the card-lifting plate 32 to move up and down to lift the cards. When the second drive rod 42 is driven to move, it can indirectly drive the sliding card pusher 20 to move back and forth to push the playing cards onto the card-lifting plate 32.

[0081] Taking the rotation of the bearing 451 by the drive shaft of the card-pulling and lifting drive mechanism 45 as an example, which is divided into four processes. Initially, the bearing 451 of the card-pulling and lifting drive mechanism 45 is positioned within the first annular arc-shaped through groove 43 of the first drive rod 41 and the second annular arc-shaped through groove 44 of the second drive rod 42. For example... Figure 7A As shown, this is the overlapping point of the opposing protrusions of the first annular arc-shaped through groove 43 and the second annular arc-shaped through groove 44. At this time, the bearing 451 is exactly in the middle of the first and second annular arc-shaped through grooves, and relative to the bearing 451 itself on the machine shaft, it is at the right end of one rotation. At this time, the card-lifting plate 32 is in a high position within the card-lifting chamber 31, and the sliding card-pushing seat 20 is also in a position far from the card-lifting plate 32. Continuing as... Figure 7B As shown, in the first process: the card-pulling and lifting drive mechanism 45 is activated, causing the bearing 451 to rotate 90° counterclockwise from the right end of the circumference to the top of the circumference. During this rotation, the rotation path of the bearing 451 coincides with the upper half of the arc-shaped through groove 44 of the second ring, and does not cause the second drive rod 42 to move, that is, the sliding card-pushing seat 20 remains stationary. However, since the first arc-shaped through groove 43 and the second arc-shaped through groove 44 are installed with opposite protrusions, the rotating bearing 451 will cause the first drive rod 41 to move horizontally to the left. The first rack 4111 fixed on the body of the first drive rod 41 also moves accordingly, and drives the arm shaft gear 4112 meshing with the first rack 4111, thereby driving the lifting rocker arm 33 to rotate downward, and finally causing the card-lifting plate 32 to descend to the low position in the card-lifting chamber 31, ready to load the cards. Continuing as follows... Figure 7CAs shown, in the second process: the bearing 451 continues to rotate 90° counterclockwise from the top point of the circumference to the left end point of the circumference. At this time, the bearing 451 rotates along the first annular arc-shaped groove 43 from the top of the first annular arc-shaped groove 43 without moving the first drive rod 41, that is, the card lifting plate 32 remains stationary at a high position. However, the bearing 451 will drive the second annular arc-shaped groove 44 and the second drive rod 42 to move horizontally to the left. At this time, the second rack 4211 fixed on the body of the second drive rod 42 also moves accordingly, and drives the compound gear set 4212 meshing with the second rack 4211, which in turn drives the pull rope 23 to wind around the winding wheel 42124, and drives the sliding card pusher 20 to move towards the card lifting plate 23 in the card receiving seat 10, thus pushing the playing cards on the wedge-shaped surface of the card receiving seat 10 onto the card lifting plate 32. Continuing as follows... Figure 7D As shown, in the third process: the bearing 451 continues to rotate counterclockwise 90° from the left end of the circumference to the bottom end. During this process, the rotating bearing 451 continues to rotate along the first annular arc-shaped groove 43, from the middle of the groove to the bottom, without driving the first drive rod 41, but only driving the second drive rod 42 to move horizontally to the right. Therefore, it also drives the second rack 4211 and the compound gear set 4212 in the opposite direction, causing the pull rope 23 to relax and lose tension. At this time, the sliding push plate seat 20 will move away from the lifting plate 32 and back to its initial position under the action of the slide seat reset member 22. Continuing as... Figure 7A As shown, in the fourth process: bearing 451 continues to rotate counterclockwise 90° from the bottom end of the circumference to the right end of the circumference. During this process, bearing 451 rotates along the second annular arc-shaped groove 44 from the bottom end of the second annular arc-shaped groove 44 towards the middle without driving the second drive rod 42. Similarly, it only drives the first drive rod 41 to move horizontally to the left, while driving the first rack 4111 and the arm shaft gear 4112 in the opposite direction, causing the lifting rocker arm 33 to rotate upward in the opposite direction, thereby driving the card lifting plate 32 to rise to the high position, i.e., the poker machine table position. In these four processes, bearing 451 rotates 360° back to the initial position.
