Description
Technical Field
The invention belongs to the technical field of mahjong machines, and particularly relates to a mahjong shuffling device of a mahjong machine.
Background
The shuffling device of the mahjong machine generally comprises a shuffling large disc, wherein the center of the shuffling large disc is rotatably connected with a bearing seat, the bottom end of the bearing seat is fixedly connected with a base plate of the mahjong machine, the top end of the bearing seat is provided with a mahjong shifting device, and the mahjong shifting device is provided with a plurality of mahjong shifting strips extending on the top surface of the shuffling large disc.
In the traditional mahjong machine, the shuffling large plate can rotate circumferentially relative to the bearing seat under the driving of the shuffling motor, and the positions of the card shifting device and the card shifting strip are kept constant, so that the card shifting strip can be used for shifting mahjong tiles on the shuffling large plate in the rotation process of the shuffling large plate.
The mahjong machine has the following disadvantages: because the position of the poker shifting strip is kept fixed in the rotation process of the shuffling big plate, the phenomena of 'dead angle for playing mahjong' and mahjong blocked between the poker shifting strip and the shuffling big plate often occur at the position of the poker shifting strip, and the shuffling process is influenced; when the shuffling large disk rotates, the shuffling large disk and the card shifting strips have larger differential speed, and when more mahjong tiles exist, the mahjong tiles can continuously impact the card shifting strips, so that shuffling noise is larger.
In order to solve the problems, the Chinese patent application with the publication number of CN108031108A discloses a batch shuffling device of a mahjong machine and a shuffling method thereof, the batch shuffling device comprises a large disk and a large disk shaft seat arranged in the center of the large disk, the large disk is rotationally connected with the large disk shaft seat, the upper surface of the large disk is provided with a poker shifting strip in a fitting manner, and a clutch device for controlling the large disk and the poker shifting strip to synchronously rotate and relatively rotate is arranged between the poker shifting strip and the large disk shaft seat.
The shuffling device has the following disadvantages: the rotating speed of the shuffling large disk is kept unchanged, the rotating state of the shuffling bars is different relative to the shuffling large disk only by controlling the shuffling bars by using the clutch, the change of the rotating state of the shuffling bars depends on the clutch, and the abrasion to parts is inevitable; when the poker bar and the large shuffling disc rotate synchronously by friction, the large shuffling disc is also abraded greatly.
On the basis, the Chinese patent application with the publication number of CN110237525A discloses a rotary tile-poking strip large disc mechanism and a mute mahjong machine, wherein the rotary tile-poking strip large disc mechanism comprises a lower large disc in a horizontal state and an umbrella-shaped upper large disc, and the lower large disc is arranged on a lower bearing seat through a lower bearing; the card-shifting device is arranged on the upper bearing seat through an upper bearing, the edge of the upper large disk is fixedly arranged on the lower large disk, and the center of the upper large disk is positioned on the periphery of the upper bearing; the planet carrier is fixedly arranged at the position where the upper bearing seat and the lower bearing seat are connected, the planet carrier is rotatably connected with a planetary wheel set, a large central wheel meshed with the planetary wheel set is arranged on the poker card shifting device, and a sun wheel meshed with the planetary wheel set is also arranged on the lower large disc.
When the motor drives the lower big disc to rotate, the sun wheel, the planetary wheel set and the big central wheel are sequentially driven, so that the power of the lower big disc is decelerated and distributed to the card poking device, and the card poking device rotates relative to the lower big disc.
The large plate mechanism for rotationally dialing the poker bars has the following disadvantages: the shuffling large disc is divided into a lower large disc and an upper large disc, and the planet carrier and the planetary wheel set are arranged in a gap between the lower large disc and the upper large disc; the planet carrier is only set to be a thin flat plate shape, and the planet carrier is clamped by the upper bearing seat and the lower bearing seat to realize circumferential positioning of the planet carrier; when the card shifting device rotates relative to the shuffling large disc, the planet carrier clamped between the upper bearing seat and the lower bearing seat bears friction from the upper bearing and the lower bearing in the whole card shuffling process, so that the service life of the planet carrier is influenced, the thickness of the planet carrier is further thinned due to long-term friction, the planet carrier is difficult to maintain circumferential positioning, and finally the transmission of a planet wheel set fails; meanwhile, because the stress area between the planet carrier and the upper bearing seat and the lower bearing seat is small, the support effect of the planet carrier on the planetary wheel set is still insufficient, and the stable operation of the planetary wheel set can be ensured only by arranging the support rollers on the outer periphery of the planet carrier.

in the early stage of shuffling, the variable-speed driving mechanism 5 drives the large shuffling disk 1 to rotate at a low speed, the power input gear 42b distributes the power of the large shuffling disk 1 to the second-stage reduction planetary gear 43a in a speed reduction way through the first-stage reduction transmission pair 42, the power of the second-stage reduction planetary gear is distributed to the card poking device 3 in a speed reduction way through the second-stage reduction transmission pair 43, so that the card poking device 3 rotates in the same direction and at a different speed relative to the large shuffling disk 1, the difference of the rotating speeds of the two is small in the process, and a large number of mahjong tiles on the top surface of the large shuffling disk 1;
in the later shuffling stage, the variable-speed driving mechanism 5 drives the large shuffling disc 1 to rotate quickly, the power input gear 42b reduces the speed of the power of the large shuffling disc 1 through the first-stage reduction transmission pair 42 and distributes the power to the second-stage reduction planetary gear 43a, the power of the second-stage reduction planetary gear is reduced by the second-stage reduction transmission pair 43 and distributes the power to the card poking device 3, so that the card poking device 3 rotates in the same direction and at different speeds relative to the large shuffling disc 1, the difference of the rotating speeds of the two is large in the process, and the situation is adapted to the situation that only a small number of mahjong tiles are left on the large shuffling disc 1 without high-frequency card.
Example 2
The shuffling device of the mahjong machine is basically the same as that of the mahjong machine in the embodiment 1, and the differences are that: the power input gear 42b and the power output gear 43b are both internal gears, and during the operation of the planetary gear reducer 4, the power input gear 42b is located on the outer ring of the first-stage reduction planetary gear 42a, and the power output gear 43b is located on the outer ring of the second-stage reduction planetary gear 43a, so that the planet carrier body 41a of the embodiment does not need to be provided with the third central hole 41e, the annular avoiding groove 41g, the first through opening 41f and the second through opening 41 h. Like embodiment 1, the card-pusher 3 and the shuffling platter 1 are rotated in the same direction in this embodiment.
Example 3
The shuffling device of the mahjong machine is basically the same as that of the mahjong machine in the embodiment 1, and the differences are that: the power input gear 42b of the present embodiment is an external gear, and the power input gear 42b is an internal gear; correspondingly, the planet carrier body 41a is only provided with the third central hole 41e and the first through opening 41f, and the annular avoiding groove 41g and the second through opening 41h are not provided.
Based on this, in the embodiment, the rotation direction of the card-shifting device 3 and the rotation direction of the shuffling large disc 1 are opposite, which remarkably accelerates the shuffling speed and shortens the shuffling time. To further increase the shuffling speed, the number of the poker bars 32 in this embodiment may be increased to four or more.
Example 4
The shuffling device of the mahjong machine is basically the same as that of the mahjong machine in the embodiment 1, and the differences are that: the power input gear 42b of the present embodiment is an internal gear, and the power input gear 42b is an external gear; correspondingly, the planet carrier body 41a is only provided with an annular avoiding groove 41g and a second through opening 41h, and the third central hole 41e and the first through opening 41f are not provided.
In this embodiment, the rotation directions of the card pusher 3 and the shuffling platter 1 are opposite to each other, as in embodiment 3.
