Description

Technical Field

[0001] The utility model belongs to the technical field of card issuing equipment, in particular to a card issuing mechanism which can avoid the obstruction of card differential discharging, and also to an automatic card issuing machine using the card issuing mechanism. Background Art

[0002] Playing cards, a common recreational item in people's lives, are widely loved by the public due to their diverse gameplay and appeal to people of all ages. With the advancement of technology, various machines have emerged to replace manual card dealing. For example, patent CN202410297529.8 provides a rotary card dealing machine, which greatly enhances the poker game experience.

[0003] Due to their different functions, the dealing wheel requires high speed to deliver cards, while the card delivery wheel requires strong force to deliver cards to the dealing wheel. This results in different power requirements for the two wheels. Current card dealing machines either use two power systems to keep the dealing and delivery wheels at the same speed, with the delivery wheel having greater power. However, this is more expensive and has a higher failure rate. Alternatively, a single power system and a reduction gear system are used, allowing the dealing wheel to rotate at high speed while the card delivery wheel rotates at a lower speed and with greater force, achieving differential card delivery.

[0004] However, due to the different speeds of the dealing wheel and the card feeding wheel, when the cards come into contact with both the dealing wheel and the card feeding wheel at the same time, part of the kinetic energy is transferred through the cards, causing the dealing wheel and the card feeding wheel to affect each other, resulting in obstruction of card playing and affecting the user experience. Utility Model Content

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

[0020] As attached Figure 1-3The illustrated card dealing mechanism avoids obstruction of differential card discharging, comprising two sets of card feeding wheels 1, a card dealing wheel 2, a drive motor 3, a reduction structure and a support plate 4. The support plate 4 is fixedly installed in the card dealing machine and serves as a card discharging channel and the bottom of a card placement slot 5. The two sets of card feeding wheels 1 are located below the support plate 4 corresponding to the card placement slot 5. The card dealing wheel 2 is located below the side of the support plate 4 corresponding to the card dealing outlet 6. The support plate 4 is provided with through holes for the card feeding wheel 1 and the card dealing wheel 2 to pass through. The card feeding wheel 1 and the card dealing wheel 2 protrude onto the upper surface of the support plate 4 through the through holes. The support plate 4 is provided with eight strip-shaped protrusions 7 at the corresponding positions of the card dealing outlet 6. The extension direction of the strip protrusions 7 is parallel to the direction of card movement. The card dealing wheel 2 is installed to the lower side of the card dealing outlet 6 through the card dealing shaft 8, and a pressure wheel shaft 10 is installed above the card dealing wheel 2 so that it can slide elastically up and down through a spring 9. A pressure wheel 11 is installed on the pressure wheel shaft 10 at the corresponding position of the card dealing wheel 2, and the pressure wheel 11 is in contact with the card dealing wheel 2. Under the action of the spring 9, the pressure wheel 11 can move adaptively up and down according to the thickness of the cards, thereby improving the stability of the cards during transmission. The driving motor 3 is fixedly installed above the pressure wheel 11, and a toothed pulley is respectively installed at the power output end of the driving motor 3 and one end of the card dealing shaft 8. The two toothed pulleys are connected by a toothed belt transmission, and a small transmission wheel 12 is fixedly installed on the other end of the card dealing shaft 8; each group of card feeding wheels 1 includes two card feeding wheels 1 and the two card feeding wheels 1 are installed on the same card feeding shaft 13 for coaxial rotation. On the top, the card feeding wheel 1 is rotatably installed to the bottom of the card placing slot 5 through the card feeding shaft 13, one end of the card feeding shaft 13 of one group of card feeding wheels 1 is installed with a large transmission wheel 15 through a one-way bearing 14, and a synchronous wheel 16 is fixedly installed on one side of the large transmission wheel 15, and one end of the card feeding shaft 13 of the other group of card feeding wheels 1 is installed with another synchronous wheel 16 through a one-way bearing 14, and the two synchronous wheels 16 are connected by a toothed belt transmission, and the large transmission wheel 15 and the small transmission wheel 12 are connected by a toothed belt transmission, and the diameter of the large transmission wheel 15 is larger than that of the small transmission wheel 12, and the large transmission wheel 15 and the small transmission wheel 12 form a reduction structure, and the two groups of card feeding wheels 1 are synchronously driven by the driving motor 3 to rotate at a low speed and the card dealing wheel 2 rotate at a high speed, and the card feeding wheel 1 and the card dealing wheel 2 form a speed difference so that the card discharging is divided into two states: low-speed feeding and high-speed discharging.

[0021] The two sets of card feeding wheels 1 are used to realize one-way transmission through the one-way bearing 14. When the card reaches the two sets of card feeding wheels 1, the card is only pushed by the four synchronous low-speed card feeding wheels 1 and is sent to the card dealing wheel 2 under high friction. When the card enters the upper part of the card dealing wheel 2, both ends of the card are driven by the high-speed card dealing wheel 2 and the low-speed card feeding wheel 1 at the same time. The high-speed card dealing wheel 2 drives the card to move rapidly, and the card will also feedback the high-speed running force to the low-speed card feeding wheel 1. However, since the card feeding shaft 13 is fixed, the card feeding wheel 1 will give the card a reverse force, forming a resistance that blocks the card dealing wheel 2 from moving forward, resulting in obstruction in card drawing. Therefore, in order to solve this problem, a one-way bearing 14 is added to the card feeding shaft 13 of the card feeding wheel 1. When the card reaches the top of the card dealing wheel 2, the card dealing wheel 2 drives the card to move quickly, and the card will transmit the high-speed running power to the card feeding wheel 1. However, under the positive transmission action of the one-way bearing 14, a relative reverse sliding is formed between the card feeding wheel 1 and the card feeding shaft 13. Even if the card feeding wheel 1 is in an idling state, the card feeding wheel 1 slides forward with the card, avoiding the two low-speed wheel shafts from forming a forward resistance to the high-speed wheel shaft, eliminating the influence of the speed difference on the card discharge, and avoiding the problem of card discharge being blocked.

[0022] Embodiment 2: An automatic card dealing machine.

[0023] As attached Figure 1-6 An automatic card dealing machine is shown, which includes a card dealing mechanism for avoiding card differential discharging obstruction as described in Example 1, and specifically also includes a casing 17. A rotating base 18 for driving the casing 17 to rotate is provided at the bottom of the casing 17, a card placing slot 5 is provided on one side of the casing 17, and a card dealing outlet 6 is provided on the other side of the casing 17. A card discharging channel is provided between the card dealing outlet 6 and the card discharging slot 5, and the card discharging channel connects the card dealing outlet 6 and the card discharging slot 5. The support plate 4 is fixedly installed in the card dealing machine and serves as the bottom of the card discharging channel and the card discharging slot 5. The drive motor 3 is fixedly installed in the casing 17, and the card feeding shaft 13 and the card dealing shaft 8 are rotatably installed in the casing 17; the pressure wheel shaft 10 is slidably installed in the casing 17, and the spring 9 is fixedly connected to the casing 17.

[0024] 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 19 and make the card pressing roller 19 swing upward. After the card stack is pushed into place, the card pressing roller 19 will press on the top of the card stack under the action of the torsion spring 9, so that the card stack is fixed in the card slot 5.

[0025] After the device is started, the drive motor 3 will start according to the preset program and drive the card feeding wheel 1 to rotate. The card feeding wheel 1 then pushes the cards to move towards the card issuing outlet 6, and then the cards are dealt through the cooperation of the card issuing wheel 2 and the card pressing wheel 11.
