[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: A card feeding mechanism that prevents card rebound.

[0023] As attached Figure 1-4 The card feeding mechanism shown in the figure can prevent the card from rebounding, and comprises a first supporting plate part 1, a second supporting plate part 2, a card feeding roller 3 and a driving motor 4. The first supporting plate part 1 is arranged at the bottom of the card slot 5 of the card dealing machine, and the second supporting plate part 2 is connected to the side of the first supporting plate part 1 in the card discharging direction. The first supporting plate part 1 is tilted downward in the direction of the second supporting plate part 2 so that the first supporting plate part 1 and the second supporting plate part 2 form an obtuse-angle bending structure. Two card feeding rollers 6 are rotatably installed under the first supporting plate part 1, and each card feeding roller 6 is fixed with a Two card feeding rollers 3 are installed, and a total of four card feeding rollers 3 are installed. Four through holes that are compatible with the card feeding rollers 3 are provided on the first supporting plate part 1. The card feeding rollers 3 protrude from the through holes to the upper surface of the first supporting plate part 1. A card pressing roller 7 is elastically swung up and down above the first supporting plate part 1. The card pressing roller 7 is at the bottom in the natural state. The card feeding roller 6 is connected to the drive motor 4 through the synchronous transmission of the toothed belt and the pulley, and the drive motor 4 drives the four card feeding rollers 3 to rotate synchronously.

[0024] As a preferred embodiment, the card feeding roller 3 is a regular polygonal prism whose outer surface is composed of multiple identical pushing planes 31 arranged evenly in a circle; six strip-shaped protrusions 8 are provided on the side of the second support plate part 2 away from the first support plate part 1, and the extension direction of the strip-shaped protrusions 8 is parallel to the direction of card movement.

[0025] The first support plate portion 1 and the second support plate portion 2 form a broken line for the card transport path. The path of the first support plate portion 1 is tilted forward, which facilitates the cards in the card pile to move toward the card outlet channel.

[0026] When an obstruction appears at the exit of the card discharging channel, one end of the card to be discharged is blocked and cannot be discharged, and the other end will retract into the card discharging channel. At this time, since the connection between the first supporting plate part 1 and the second supporting plate part 2 is bent, the connection will also stop the other end of the card, preventing it from retracting into the card discharging channel on the first supporting plate part 1. The card is maintained in the card discharging channel on the second supporting plate part 2, and the card at the rear remains in an idling state on the first supporting plate part 1, thereby avoiding the problem of card stacking and preventing the card discharging channel from being blocked, thereby improving the smoothness of card discharging. In addition, the photoelectric switch 12 is used to detect the transmission status of the cards in the card discharging channel, and the photoelectric switch 12 can be used to calculate the card discharging amount to achieve the effect of quantitative card discharging.

[0027] Embodiment 2: An automatic card dealing machine.

When the torsion spring is in a natural state, the lower end of the swing arm 13 is inclined toward the card outlet 11, and the card pressing roller 7 can be used to apply pressure and position the card stack so that the card stack can be stably placed in the card slot 5, and the card pressing roller 7 is set to a state of tilting downward in the card discharging direction, which can facilitate the user to place the card stack. A card issuing mechanism for ejecting cards from the card outlet 11 and a control mechanism for controlling the operation of the card issuing machine are also provided in the casing 9.

[0029] When in use, the card stack is pushed into the card slot 5 from one side. During the pushing process, the card stack will support the card pressing roller 7 and make the card pressing roller 7 swing upward. After the card stack is pushed into place, the card pressing roller 7 will press against the top of the card stack under the action of the torsion spring, so that the card stack is fixed in the card slot 5.

[0030] After the device is started, the drive motor 4 will start according to the preset program and drive the card feeding roller 3 to rotate, and the card feeding roller 3 will then push the cards to move towards the card issuing outlet 11, and then the cards will be issued through the card issuing mechanism.
