[0002] Mahjong is not only a recreational activity, but also a competitive sport. It not only helps to improve people's comprehensive thinking ability and strategic planning ability, but also improves people's willpower. With people's love for mahjong competition and in order to save participants' time, fully automatic mahjong machines that can automatically shuffle and code cards have emerged.

[0003] In the existing mahjong machine, the conveyor belt of the card feeding device is wrapped around the card suction wheel. During the card sorting process, the mahjong cards are attracted by the magnets on the card suction wheel, and the mahjong cards hit the conveyor belt wrapped around the card suction wheel. As the use time increases, the conveyor belt will not only become loose due to the long-term impact of mahjong cards, but also may break, affecting normal use. In addition, when replacing the conveyor belt, many parts need to be disassembled, which affects the later maintenance. Utility Model Content

[0032] (Example 1)

[0033] See Figure 1-4 The mahjong machine card feeding device of this embodiment includes a frame 1, a power device 2, a card suction wheel 3, a card feeding wheel 4 and a conveyor belt 5. The power device 2 is fixed on the outside of the frame 1, and the card suction wheel 3 and the card feeding wheel 4 are rotatably arranged on the inside of the frame 1. The power device 2 is transmission-connected with the card suction wheel 3 and the card feeding wheel 4; a conveyor frame 6 is arranged on the inside of the frame 1, and the conveyor frame 6 is detachably fixed on the frame 1, and the conveyor belt 5 is arranged around the card feeding wheel 4 and the conveyor frame 6.

[0034] Specifically, in the present embodiment, the power device 2 adopts a motor, which is fixedly mounted on one side of the frame 1, and a driving gear is fixed on the output shaft of the motor. The card suction wheel 3 and the card feeding wheel 4 are arranged on the other side of the frame 1, and a driven gear is fixed on one side of the card suction wheel 3 and the card feeding wheel 4. The driving gear meshes with the driven gear. When the motor is running, the card suction wheel 3 and the card feeding wheel 4 can be driven to rotate at the same time. A conveyor frame 6 is arranged on the frame 1 toward the card feeding wheel 4 side, and the conveyor frame 6 is detachably connected to the frame 1. The conveyor belt 5 is arranged around the card feeding wheel 4 and the conveyor frame 6. When the card feeding wheel 4 rotates, the conveyor belt 5 is driven to rotate synchronously. Three magnets (not shown in the figure) are evenly arranged on the outer peripheral surface of the card suction wheel 3 for adsorbing mahjong tiles. When the motor is running, the mahjong tiles in the shuffling area pass under the card suction wheel 3, are adsorbed by the card suction wheel, and then transmitted to the conveyor belt, and the conveyor belt 5 transmits the mahjong tiles to the stacking area. The conveyor belt 5 in this embodiment is wrapped around the card feeding wheel 4 and the conveyor frame 6. After the mahjong tiles are adsorbed by the magnet on the card suction wheel 4, they are conveyed to the conveyor belt 5, which prevents the mahjong tiles from hitting the conveyor belt 5 when being adsorbed, thereby extending the service life of the conveyor belt; and the conveyor frame 6 is detachable from the frame body 1. When the conveyor belt 5 needs to be replaced, it can be replaced by simply removing the conveyor frame 6, which is convenient for later maintenance.

[0035] See Figure 2The conveyor frame 6 includes a conveyor platform 6-1 and a guide wheel assembly, and the conveyor belt 5 is arranged around the card feeding wheel 4 and the guide wheel assembly. The conveyor platform 6-1 is arranged below the conveyor belt 5 on one side of the card feeding channel. The conveyor platform 6-1 can support the mahjong tiles on the conveyor belt 5 and enhance the stability of the card feeding. As a preferred solution of this embodiment, the height of the conveyor belt 5 on one side of the card feeding channel matches the height of the top of the card suction wheel 3, thereby enhancing the stability of the card feeding.

[0036] A cover 8 is provided on the side of the frame 1 facing the card-feeding wheel 4. The cover 8 is fixedly connected to the frame 1 and covers parts such as the card-feeding wheel 4, the card-absorbing wheel 3, the conveyor belt 5, the conveyor frame 6 and the tensioning mechanism 7.

[0037] Since the conveyor belt 5 does not wrap around the card-feeding wheel 4, a small gap area is formed between the card-feeding wheel 4 and the conveyor belt 5. The mahjong tiles may be stuck in the gap area during the process of being transported from the card-feeding wheel 4 to the conveyor belt 5. Therefore, a transition rod 8-1 is provided on the cover body 8. Figure 1 The transition rod 8 - 1 is arranged in the gap area between the card suction wheel 3 and the conveyor belt 5 to ensure that the mahjong tiles are smoothly conveyed to the conveyor belt 5 .

[0038] In order to ensure that the conveyor belt 5 remains in a taut state for a long time during use, a tensioning mechanism 7 is also provided in this embodiment. The tensioning mechanism 7 includes a tensioning wheel 7-1, a pull rod 7-2 and a tension spring 7-3. The middle part of the pull rod 7-2 is rotatably arranged on the frame 1. One end of the tension spring 7-3 is fixed to the frame 1, and the other end is fixed to one end of the pull rod 7-2. The tensioning wheel 7-1 is rotatably arranged on the other end of the pull rod 7-2. The tensioning wheel 7-1 is located on the same side of the frame 1 as the conveyor belt 5 and is close to the conveyor belt 5. The pull rod 7-2 is located on the other side of the frame 1.

[0039] The conveyor belt 5 of the utility model is wrapped around the card feeding wheel 4 and the conveyor frame 6. After the mahjong tiles are adsorbed by the magnet on the card suction wheel 3, they are conveyed to the conveyor belt 5, which prevents the mahjong tiles from hitting the conveyor belt 5 when being adsorbed, thereby extending the service life of the conveyor belt 5; and the conveyor frame 6 is detachable from the frame body 1. When the conveyor belt 5 needs to be replaced, it can be replaced by simply removing the conveyor frame 6, which is convenient for later maintenance.

[0040] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
