In order to solve the problem that the friction force between the tile sucking structure of the mahjong machine and the mahjong tiles 70 is large in the prior art, the application provides the tile sucking structure with the protruding tile sucking position and the mahjong machine.

The mahjong machine of the present application has a structure in which the tile suction position protrudes, and the structure is installed inside the mahjong machine and is used to suck and transfer the mahjong tiles 70 on the shuffling tray 60 of the mahjong machine.

As shown in fig. 1 and 2, the tile sucking structure with the protruding tile sucking position in the present application includes a tray body 10 and a tile sucking part 20, the tile sucking part 20 is connected with the circumferential direction of the tray body 10, the tile sucking part 20 has a tile sucking surface 21 protruding outward, the contact area of the tile sucking surface 21 and the mahjong tiles 70 is smaller than the back surface area of the mahjong tiles 70, and the contact surface of the tile sucking surface 21 and the mahjong tiles 70 is a smooth surface.

Under the condition of not considering friction force and dead weight, because the magnetic force is attenuated along with the increase of the distance, after the mahjong tiles 70 and the tile sucking part are adsorbed together and stabilized, the distance between the mahjong tiles 70 and the tile sucking part is fixed and is the minimum distance which can be reached between the mahjong tiles 70 and the tile sucking part, and the included angle between the strip direction of the strip-shaped magnet in the mahjong tiles 70 and the connecting line direction between the two magnets of the tile sucking part is 0 degree; in reality, due to the existence of self weight and friction force, the included angle between the bar direction of the bar magnet in the mahjong tile 70 and the connecting line direction between the two magnets of the tile sucking part is measured for many times, the average value r is taken, the value of r gradually converges to a constant p along with the increase of the measuring times, and the value of the constant p is very close to 0 under the condition that only the influence of the friction force on r is considered. This indicates that: the included angle between the bar direction of the bar magnet in the mahjong tile 70 and the connecting line direction between the two magnets of the tile suction part is in a range, the range is increased along with the increase of the torque for hindering the mahjong rotation generated by the friction force between the mahjong tile 70 and the tile suction part, and is reduced along with the decrease of the torque for hindering the mahjong rotation generated by the friction force between the mahjong tile 70 and the tile suction part, the technicians in the field can face the long side of the mahjong tile 70 to the movement direction by controlling the torque for hindering the mahjong rotation generated by the friction force between the mahjong tile 70 and the tile suction part and the included angle between the bar direction of the bar suction body and the rotating shaft of the tile suction wheel, so that the mahjong tile 70 is directly sent to the tile sending track 50 in the length direction, the direction of the mahjong tile 70 does not need to be adjusted, the time and the structure are saved, and the efficiency is improved. The torque which is generated by the friction force between the mahjong tiles 70 and the tile sucking part and hinders the rotation of the mahjong is reduced by reducing the moment of the friction force of the tile sucking part on the mahjong tiles 70, so that the included angle between the bar direction of the bar-shaped magnet in the mahjong tiles 70 and the connecting line direction between the two magnets of the tile sucking part is controlled in a smaller range, the mahjong tiles 70 are conveniently sent into a track, namely, the value of a constant p is reduced, and the constant p is closer to 0.

When the tile sucking structure with the protruding tile sucking position is used, the tile sucking structure with the protruding tile sucking position is provided with the tray body 10, so that the tile sucking structure with the protruding tile sucking position can be installed in a mahjong machine through the tray body 10 and is in driving connection with the mahjong machine, and the tray body 10 is located above the tile shuffling tray 60 of the mahjong machine. Therefore, when the mahjong machine shuffles, the mahjong machine can drive the tray body 10 to rotate above the shuffling tray 60, and the mahjong tiles 70 on the shuffling tray 60 of the mahjong machine are sucked through the tile sucking part 20, so that the tile sucking structure with the protruding tile sucking position can sequentially convey the mahjong tiles 70 on the shuffling tray 60 to the tile conveying track 50 in the mahjong machine along with the rotation of the tray body 10. When the mahjong tiles 70 on the shuffling tray 60 are sucked by the tile suction unit 20, the action surface of the tile suction unit 20 on the mahjong tiles 70 is the back surface of the mahjong tiles 70. Or the mahjong tiles 70 are adsorbed on the tile sucking part 20, the contact surface of the mahjong tiles 70 and the tile sucking part 20 is the back surface of the mahjong tiles 70. At this time, since the tile suction part 20 has the tile suction surface 21 protruding outward, the contact area of the tile suction surface 21 and the mahjong tiles 70 is smaller than the back surface area of the mahjong tiles 70, and the contact surface of the tile suction surface 21 and the mahjong tiles 70 is a smooth surface, the friction force applied to the mahjong tiles 70 by the tile suction position can be mainly concentrated near the rotation center of the mahjong tiles 70, so that the blocking torque caused by the friction force is small, which is beneficial to the rotation of the mahjong tiles 70 after being absorbed, and the blocking is small. Further, by providing such a configuration, when the mahjong tiles 70 are dropped from the tile suction part 20 and are carried into the tile feeding rail 50, it is possible to ensure that the mahjong tiles 70 can be more easily separated from the tile suction part 20. Therefore, the tile sucking structure with the protruding tile sucking position effectively solves the problem that the friction force between the tile sucking structure of the mahjong machine and the mahjong tiles 70 is large in the prior art.

In the present application, the surface of the tile suction surface 21 that contacts the mahjong tile 70 is a smooth surface, and generally means that the roughness of the tile suction surface 21 is smaller than the roughness of the tile suction portion 20 at other positions. In addition, the roughness of the tile suction surface 21 can be changed according to specific use requirements or mahjong materials.

It should also be noted that the center of the disk 10 in this application has a connecting shaft hole for driving connection with the mahjong machine, and the thickness of the connecting shaft hole is larger than the thickness of the disk 10 at other positions.

Specifically, the card suction portion 20 has a card suction projection 22 in the thickness direction of the tray body 10, and the card suction projection 22 has a card suction surface 21. Through the arrangement, when the mahjong machine drives the plate body 10 to rotate relative to the shuffling plate 60 and the mahjong tiles 70 on the shuffling plate 60 are sucked by the tile sucking part 20, the mahjong tiles 70 on the shuffling plate 60 can be adsorbed on the tile sucking bulges 22 and cannot contact with the plate body 10 after the mahjong tiles 70 are sucked by the tile sucking part 20 in the thickness direction of the plate body 10, so that the contact area between the mahjong tiles 70 and the tile sucking structure with the protruding tile sucking position can be effectively reduced, and the friction force between the mahjong tiles 70 and the tile sucking structure with the protruding tile sucking position is effectively reduced. That is, in the present application, there is a height difference between the card suction surface 21 and the surface of the tray 10 where the card suction part 20 is located, that is, the height difference is formed by arranging the card suction protrusion 22, so as to ensure that the mahjong tiles 70 only contact with the card suction surface 21 and do not contact with other parts.

Also, in one embodiment of the present application, the card suction projection 22 is gradually narrowed in a direction from a side contacting the tray body 10 to a side of the card suction surface 21, that is, a sectional area of the card suction projection 22 in this direction is smaller closer to the card suction surface 21.

In one embodiment of the present application, the card suction surface 21 is parallel to a plane on one side in the thickness direction of the tray body 10. After the mahjong tiles 70 are adsorbed on the tile sucking surface 21, the mahjong tiles 70 can rotate for a period of time along with the disk body 10, so that the stability between the mahjong tiles 70 and the tile sucking structure with the protruding tile sucking position can be ensured through the arrangement, and the mahjong tiles 70 can not fall off in the rotating process.

Specifically, at least one abutting convex point is arranged on the card sucking surface 21. The friction between the mahjong tiles 70 and the tile suction surface 21 can be further effectively reduced by arranging the contact salient points. That is, by providing the abutment projection on the tile suction surface 21 and then allowing the back surface of the mahjong tile 70 to abut on the abutment projection after the mahjong tile 70 is sucked on the tile suction surface 21, the contact area between the mahjong tile 70 and the tile suction surface 21 can be reduced.

Preferably, the plurality of abutment protrusions are provided at intervals. Further preferably, the plurality of abutment protruding points are arranged around the circumferential direction of the card suction surface 21. Since the mahjong tiles 70 rotate with the tray body 10 for a while after the mahjong tiles 70 are adsorbed on the tile suction surface 21, the friction between the mahjong tiles 70 and the tile suction surface 21 is reduced, and the stability between the mahjong tiles 70 and the tile suction surface 21 is also considered to prevent the mahjong tiles 70 from falling off the tile suction surface 21 before entering the tile delivery track 50.

Specifically, the tile sucking structure with the protruding tile sucking position further comprises at least one magnet 30, at least one part of the magnet 30 is arranged inside the tile sucking part 20, and when the mahjong tiles 70 are adsorbed on the magnet 30, the abutting convex points abut against the mahjong tiles 70. That is, in the present application, when the tile suction structure with the protruding tile suction position sucks the mahjong tiles 70 from the shuffling board 60 of the mahjong machine, the mahjong tiles 70 are attracted to the tile suction surface 21 by the magnetic force between the magnet 30 and the magnetic attraction structure embedded in the mahjong tiles 70.

In one embodiment of the present application, the magnet 30 is embedded inside the tile suction protrusion 22. The overall structure of the tile suction part 20 can be effectively ensured to be more compact by the arrangement, and the magnet 30 can be effectively prevented from falling off the tile suction protrusion 22 by the arrangement. Therefore, the arrangement effectively ensures the use performance of the mahjong tile sucking structure with the protruding mahjong tile sucking position.

In another embodiment of the present application, a portion of the magnet 30 is embedded inside the tile suction protrusion 22, and another portion of the magnet 30 is exposed outside the tile suction surface 21. With this arrangement, the magnetic attraction effect between the magnets 30 and the magnetic attraction structure in the mahjong tiles 70 can be effectively ensured, and the mahjong tiles 70 on the shuffling tray 60 can be more easily attracted to the tile attracting surface 21 by the tile attracting portion 20. Preferably, the plane of one end of the magnet 30 exposed outside the tile absorbing surface 21 and the tile absorbing surface 21 are positioned on the same plane. Of course, in the present application, the flat surface of the magnet 30 exposed to the outside of the medal sucking surface 21 may be the same plane as the abutment convex point.

Alternatively, the card suction portion 20 may be plural, and the plural card suction portions 20 may be provided at intervals around the periphery of the tray 10. With the arrangement, after the disk body 10 rotates for a circle relative to the mahjong tile shuffling disk 60, a plurality of mahjong tiles 70 can be sucked by the tile sucking parts 20, so that the mahjong tile shuffling time of the mahjong machine can be effectively shortened, and the tile sucking efficiency of the tile sucking structure with the protruding tile sucking position is improved. Moreover, when the tray body 10 rotates relative to the card shuffling tray 60, the rotation stability of the tray body 10 can be effectively ensured, the stress of the tray body 10 is more uniform, and the service life of the tray body 10 is prolonged.

Optionally, the card-sucking structure with the protruding card-sucking position further comprises a card-shifting part 40, and the card-shifting part 40 is connected with the tray body 10. With this arrangement, after the mahjong tiles 70 on the tile suction part 20 fall off from the tile suction part 20 and enter the tile delivery track 50, the mahjong tiles 70 on the tile delivery track 50 can be shifted from the partitioned tile suction tray by the tile shifting part 40, so that the mahjong tiles 70 on the subsequent tile suction part 20 can be ensured to easily fall on the tile delivery track 50.

Optionally, the direction in which the card-setting portion 40 protrudes from the tray body 10 is the same as the protruding direction of the card-sucking surface 21.

Specifically, the distance from one end of the card-shifting portion 40 far away from the tray 10 to the tray 10 is less than or equal to the distance from one end of the card-sucking portion 20 far away from the tray 10 to the tray 10. Preferably, in the radial direction of the disk 10, the sum of the distance from one end of the card-shifting portion 40 away from the center of the disk 10 to the center of the disk 10 and 0.5 times of the length of the mahjong tiles 70 is greater than or equal to the distance from the center of the mahjong tiles 70 adsorbed by the tile adsorbing portion 20 to the center of the disk 10. With such an arrangement, after the mahjong tiles 70 on the tile sucking part 20 fall off from the tile sucking part 20 and enter the tile conveying track 50, along with the rotation of the tray body 10, the tile shifting part 40 behind the tile sucking part 20 in the rotation direction of the tray body 10 can be ensured to be in contact with the mahjong tiles 70 on the tile conveying track 50 and can push the mahjong tiles 70 to move on the tile conveying track 50 in the direction far away from the tray body 10.
