Description

Technical Field

[0001] The utility model belongs to the technical field of mahjong machine card suction equipment, and in particular relates to a full-automatic mahjong machine card suction and conveying mechanism. Background Art

[0002] The card suction device of the mahjong machine is an important component of the automatic mahjong machine. It is used to pick up the shuffled mahjong tiles from the shuffling plate, and deliver the picked-up mahjong tiles to the entrance of the mahjong tile conveying path, and then send the mahjong tiles to the stacking mechanism through the card feeding belt for stacking. However, the existing card suction device has a complex structure, a long card suction and conveying distance, an unreasonable design, and many parts, which makes the stability poor and is prone to damage after long-term work, which undoubtedly reduces the user experience.

[0003] In order to solve the deficiencies in the prior art, people have conducted long-term explorations and proposed various solutions. For example, a Chinese patent document discloses a mahjong machine conveying transmission structure [202322109907.9], including a conveying bracket, a card suction wheel is provided on one side of the conveying bracket, and a conveying motor is provided on the other side of the conveying bracket. One side of the conveying bracket is connected to a conveying seat, and a conveying channel is formed between the conveying seat and the conveying bracket. At least two conveying rollers located on one side of the card receiving plate and made of flexible material are sequentially arranged in the conveying channel. The conveying rollers are all connected to a linkage assembly that can make the conveying rollers rotate synchronously in the same direction when the conveying motor drives the card suction wheel to rotate circumferentially. The linkage assembly is arranged on one side of the conveying bracket and on one side of the conveying motor. This solution solves the problem of the long conveying distance between the existing card suction wheel and the card output wheel to a certain extent, but the solution still has many shortcomings, such as a large number of internal components, resulting in a high failure rate and other problems.

[0004] For another example, a Chinese patent document discloses a card loading device and a mahjong machine [202021761997.X], wherein the card loading device at least includes a card loading bracket, a card suction wheel, a separation mechanism, and a card delivery wheel, the card suction wheel is provided with a first drive device, the separation mechanism is adjacent to the card suction wheel, and the card delivery wheel is adjacent to the side of the separation mechanism away from the card suction wheel and is provided with a second drive device. Although this solution alleviates the problem of the long conveying distance between the existing card suction wheel and the card delivery wheel to a certain extent, this solution still has many shortcomings, such as the gear sets are all arranged at one end away from the motor shaft, and due to the long connection distance with the motor, the eccentricity of each gear will appear after long-term use.
