The card outlet is prone to jamming. The tensioning structure has many accessories and is difficult to install, requiring a lot of manpower and material resources, and the volume of the large plate is small.

[0004] Therefore, a mahjong machine conveying structure is provided to solve the above problems. Utility Model Content

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] It should be understood that the terms "upper", "lower", "left", "right", "front", "back", "middle", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0028] Reference Figure 1-11, an embodiment of the present invention provides a mahjong machine conveying structure, including a transmission frame 1, a conveying trough 2, a card-absorbing wheel 4 and a double-pressure tensioning assembly 5; the transmission frame 1 is equipped with a card-discharging wheel 6, the conveying trough 2 is equipped with a connecting angle 3, the card-absorbing wheel 4 is equipped with a conveyor belt 7, the double-pressure tensioning assembly 5 includes a bracket 51, a tensioning wheel 52, a double-pressure torsion spring 53 and a tensioning wheel shaft 54; the card-discharging wheel 6 is located between the transmission frame 1 and the conveying trough 2, the connecting angle 3 is installed in the The conveying trough 2 is on one side away from the transmission frame 1, the card suction wheel 4 is located between the transmission frame 1 and the conveying trough 2, the conveyor belt 7 is sleeved on the card suction wheel 4, the double-pressure tensioning assembly 5 is located on the transmission frame 1, the bracket 51 is located on both sides of the double-pressure tensioning assembly 5, the tensioning wheel 52 is located between the brackets 51, the double-pressure torsion spring 53 is located on the adjacent inner side wall of the bracket 51, and the tensioning wheel shaft 54 is installed on the bracket 51 and passes through the tensioning wheel 52.

[0029] As can be understood, the travel distance from the shuffling tray to the card outlet is shorter, and a reasonable waiting area of 2-3 mahjong tiles is retained, maximizing the space on the shuffling tray while ensuring efficient and stable card loading. The entire device has been simplified from the traditional structure of a conveying motor 8 driving a rubber wheel (or motor-driven gear), a tensioner 52, a card outlet wheel, a card-supply wheel guide wheel, and a card-supply wheel to a card-supply wheel 4, a tensioner 52, and a card-discharging wheel 6. By changing the single-sided tensioner wheel structure to a double-pressure tensioner assembly 5, the conveyor belt 7 always runs in the center, reversing the traditional structure's tendency to deviate, significantly improving operational stability and the service life of the conveyor belt 7. The card-discharging wheel 6 employs grooves and rubber rings at both ends to enhance the inertia of card removal and the friction of pushing the mahjong tiles. This reduces the drop and noise when the mahjong tiles are pushed out of the conveyor outlet, and also allows the tiles to be pushed farther out of the conveyor outlet, preventing them from getting stuck at the card outlet.

[0030] In one embodiment, a through hole is provided at the central axis position of the card-absorbing wheel 4, a small shaft sleeve 9 is provided on one side of the through hole, a magnet bin 10 is provided on the card-absorbing wheel 4, a coupling sleeve 11 is clamped in the through hole, a card-absorbing wheel shaft 12 is clamped in the coupling sleeve 11, one end of the coupling sleeve 11 is hexagonal and the other end is cylindrical, a motor 8 is provided on the side of the transmission frame 1 away from the conveying trough 2, the motor 8 is connected to the card-absorbing wheel shaft 12 through the coupling sleeve 11, two mounting buckles 21 are provided on the side of the conveying trough 2 close to the transmission frame 1, and corresponding buckle notches are provided on the transmission frame 1, grooves are provided at both ends of the card-discharging wheel 6, rubber rings are installed in the grooves, and the conveyor belt 7 abuts against the tensioning wheel 52 on the double-pressure tensioning assembly 5.

[0031] As can be appreciated, the installation of mounting clips 21 on the conveyor trough 2 and the corresponding clip notches on the transmission frame 1 make assembly of the card feeding and loading mechanism much easier and simpler, requiring as few as two fastening screws. The coupling sleeve 11 allows the motor 8 to directly drive the card suction wheel 4, eliminating the need for an intermediate drive. This not only simplifies the transmission structure but also shortens the travel distance between the card suction wheel 4 and the card outlet, freeing up more space within the shuffling tray. As mahjong tiles become larger and larger, the need for a larger shuffling tray to hold more cards is becoming increasingly important. The coupling sleeve 11 that directly drives the card-absorbing wheel 4 adopts a hexagonal shape to match the card-absorbing wheel 4, and is connected to the motor shaft with a single-sided flat square structure of a round shaft in the middle. The motor 8 can be connected to the screw mounting column on the transmission frame 1 with screws. The hexagonal and flat square round holes of the coupling sleeve 11 have a demolding and whitening design for easy disassembly and assembly. A small sleeve 9 is embedded in the middle of one end of the cylinder at the other end of the coupling sleeve 11, and a double flat square round shaft is used to insert the small sleeve 9 from one end of the conveying trough 2. The card-absorbing wheel shaft 12 has a double flat square head, is hollow and threaded, and is connected to the conveying trough 2 with countersunk screws. Except that the motor 8 is connected to the transmission frame 1, the card-absorbing wheel shaft 12 and the conveying trough 2 with screws, the coupling sleeve 11, the card-absorbing wheel 4, and the small sleeve 9 are all directly disassembled and assembled manually. Compared with the traditional conveying structure, this conveying structure has greater inertia in delivering cards from the card outlet, can deliver cards farther and is less likely to get stuck; the double-pressure tensioning structure is simple with fewer accessories, is safe and reliable, saves labor, and can basically prevent the belt from deviation; the design of the coupling sleeve 11 directly drives the card suction wheel 4 with the motor 8, making the plate content larger, the conveying structure simpler, and more convenient to disassemble and assemble, saving more labor. These optimization innovations also make the conveying structure more stable and reliable.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
