Description

Technical Field

[0001] The invention belongs to the technical field of mahjong machines, and in particular relates to a card-raising mechanism for a mahjong machine. Background Art

[0002] Playing mahjong is a bridge for people to relax, communicate or enhance their feelings, and it is favored by more and more people. In response to usage needs, mahjong tables on the market are constantly being updated, with a wide variety of types and complete functions. As a popular entertainment product, automatic mahjong machines are very practical and operational. They can automatically shuffle and sort cards, which can greatly save people from the tedious steps of manual shuffling, stacking, and sorting cards during the game, saving time and providing convenience to people. For this reason, the market share of automatic mahjong machines is also increasing, and they are gradually entering entertainment venues and homes.

[0003] The structural features of the existing mahjong machine are: an opening and closing plate for inserting mahjong tiles is arranged at the center of the mahjong table. As for the card removal, one method is to arrange four slender rectangular card removal openings around the mahjong table, each of which is provided with a cover plate, and a lifting device is arranged below each card removal opening; the other method is to arrange four inclined card removal openings at a point in the middle of the mahjong table, each of which is provided with a cover plate, and the mahjong tiles are pushed onto the cover plate by a card pulling device, and the game can start after the cover plate is raised.

[0004] A turntable is provided under the opening and closing plate and the cover of the mahjong table to stir the mahjong tiles put in by opening the opening and closing plate. After stirring, the posture control mechanism configures a certain number of tiles into a two-layer structure, and the suction and delivery mechanism transports and supplies the two-layer tiles to each card distribution table, and then the transfer mechanism horizontally transfers the two-layer tiles on each card distribution table to the cover. This arrangement requires a separate motor to be designed for the head box and the card pushing mechanism, which results in at least 8 motors required for a similar structure, increasing the volume of the mahjong machine, and also increasing the weight and cost of the mahjong machine. The large number of components makes the probability of later maintenance higher, and the promotion effect is not good; moreover, the existing mahjong machines start to touch the tiles after the mahjong tiles are raised, and can only start to prepare for playing cards after touching the tiles.

The "connection" and "coupling" mentioned in this application, under reasonable circumstances (not constituting a self-contradiction), include direct and indirect connections (couplings).

[0037] Example:

[0038] like Figure 1-8 As shown, this embodiment provides a mahjong machine card lifting mechanism, including a head box mechanism, a card pushing mechanism, a card pulling mechanism and an oblique card lifting mechanism connected in sequence, the head box mechanism includes a head box body 101 and a head box driving motor 102 installed on the head box body 101, and a driving gear 103 is arranged in the head box body 101, and the driving gear 103 is connected to the motor shaft of the head box driving motor 102; it should be noted that the main structure of the head box mechanism remains unchanged, that is, it only adds a driving gear 103 on the basis of the existing technology, and other structures are not increased or decreased, so detailed description is not made; it should be noted that the oblique card lifting mechanism can adopt the existing technology without any adjustment;

[0039] The card pushing mechanism includes a card pushing mechanism 201, a card raising bar 202 and a sinking bar 203 arranged in sequence from the outside to the inside of the mahjong machine. An adjusting gear 204 is installed on the inner side of the mounting frame below the card raising bar 202 to drive the card pushing mechanism 201 to push the mahjong tiles on the card raising bar 202 to the sinking bar 203, and drive the mahjong tiles on the sinking bar 203 to rise to the tabletop; the adjusting gear 204 is meshed with the driving gear 103 through the first gear set 218 to drive the head box drive motor 102 to ... The adjusting gear 204 rotates; it should be noted that the card-raising bar 202, that is, the existing card-raising bar part, has no structural changes, and the adjusting gear 204 arranged inside it has no changes, so the connection structure between the adjusting gear 204 and the card-pushing mechanism 201 is also the same as that of the prior art, and no detailed description is given, and the connection structure between the sinking bar 203 and the adjusting gear 204 also belongs to the prior art, and both are driven to rise and fall by swinging, which is described in detail in the prior art, so no detailed description is given;

[0040] The card pulling mechanism includes a card pulling belt and a card pulling driving mechanism. The card pulling driving mechanism drives the card pulling belt to pull the mahjong cards on the card raising bar 202 that are not in contact with the card raising bar 202 to the oblique card raising mechanism.

[0041] Working principle: the head box mechanism first uses the head box driving motor 102 to drive the upper and lower cards, pushes all the mahjong tiles onto the card raising bar 202 of the card pushing and raising mechanism, and then starts the card pulling belt to pull away the multi-layer mahjong tiles on the card raising bar 202 that are not in direct contact with it, and brings them to the inclined card raising mechanism to be raised to the tabletop; after the card pulling belt pulls away the multi-layer mahjong tiles on the card raising bar 202 that are not in direct contact with it, the head box driving motor 102 drives the adjusting gear 204 to move through the active gear 103, and the adjusting gear 204 drives the card pushing mechanism 201 to push the remaining layer of mahjong tiles on the card raising bar 202 onto the sinking bar 203, and then the adjusting gear 204 drives the sinking bar 203 to be raised to the tabletop, and then the card game can begin.

[0042] During the use of the present invention, the head box mechanism and the card pushing mechanism can be driven by a head box driving motor 102, and the two motors that were originally needed to be used are combined into one motor to realize the head box mechanism and the card pushing mechanism, saving one motor. When applied to the whole machine, four motors can be saved, and only four motors are needed to realize the head box mechanism and the card pushing mechanism in four directions. This change only requires the addition of the driving gear 103 and the first gear set 218, and the structure is simpler and more practical, saving the overall volume, weight, and number of motors of the mahjong machine, reducing the cost, and being suitable for promotion; the card pulling belt can pull the mahjong tiles on the card lifting bar 202 that are not in contact with the card lifting bar 202 to the oblique card lifting mechanism, and then use the oblique card lifting mechanism to lift them to the table top, and a layer of mahjong tiles can be left on the card lifting bar 202, such as the thirteen cards that everyone is used to. When the sinking card bar rises to the table top, the cards can be played directly, saving the time of touching the cards, that is, saving the time of playing cards, and improving the efficiency.

[0043] The driving gear 103 is located between the head box driving motor 102 and the card pushing slot wheel 104 of the head box mechanism. The card pushing slot wheel 104 is connected to the internal structure of the head box and is not described in detail. The driving gear 103 is located between the head box driving motor 102 and the card pushing slot wheel 104 of the head box mechanism, which will not affect the action of the card pushing slot wheel 104. A notch is provided on one side of the head box body 101 for the first gear set 218 to mesh with the driving gear 103 after passing through the notch. The driving gear 103 is connected to the head box driving motor 102 through a first one-way bearing, and the card pushing slot wheel 104 is connected to the head box driving motor 102 through a second one-way bearing, and the first one-way bearing and the second one-way bearing have opposite directions of rotation, wherein the first one-way bearing and the second one-way bearing have opposite directions of rotation, as long as the head box driving motor 102 rotates forward and reverse, different controls can be achieved respectively, and there will be no mutual interference between the two.

[0044] What needs to be further explained in this embodiment is that a swing rod 105 is provided on the side of the card pushing groove wheel 104 close to the head box driving motor 102, one end of the swing rod 105 is rotatably connected to the inner wall of the head box body 101, and a first bearing slidably connected to the annular track groove 1041 on one side of the card pushing groove wheel 104 is installed in the middle of the swing rod 105, and the swing of the swing rod 105 can be controlled by the rotation of the card pushing groove wheel 104, which is the same as the prior art; the other end of the swing rod 105 is provided with a second bearing 107 connected to the card receiving seat 106 of the head box mechanism, which is used to drive the card receiving seat 106 to rise and fall, which is the same as the prior art and will not be explained in detail. It should be noted that the swing rod 105 in this embodiment is preferably an S-shaped structure, which can appropriately increase the swing amplitude of the swing rod 105, so as to adjust the spacing of the card receiving seat 106 when swinging as needed.

[0045] It should be further explained in this embodiment that the annular track groove 1041 is provided with a plurality of descending sections that cooperate with the swing rod 105 to drive the card holder 106 to descend in sequence, and an ascending section 1042 that drives the card holder 106 to ascend; the descending section includes a first descending section 1043 and a second descending section 1044. The magnetic control provided on the existing annular track groove is provided at different sections to facilitate the control of changing the movement direction of the card pushing slot wheel.

[0046] It should be further explained in this embodiment that the first gear set 218 is a reduction gear set, and the diameter of each gear in the reduction gear set is larger than the diameter of the driving gear 103 and smaller than the diameter of the adjusting gear 204, so as to reduce the rotation speed transmitted from the driving gear 103 to the adjusting gear 204. It should be noted that in order to achieve the purpose of deceleration, in practice, the driving gear 103 will be designed to be relatively small, the speed of the head box driving motor remains unchanged, and the speed of the driving gear 103 is also fixed. Then, the size of the driving gear 103 and the first gear set 218 is designed according to the gap, and the gear in the first gear set 218 that meshes with the driving gear 103 is designed to be larger as much as possible to achieve the deceleration effect on the speed of the head box driving motor. It can be directly meshed with the adjusting gear as needed, or a larger gear can be designed to decelerate again, and then meshed with the adjusting gear to achieve the deceleration effect in turn. It should be further noted that no matter how many gears are designed in the first gear set 218, the diameter of all the gears in the first gear set 218 is larger than the diameter of the driving gear 103, but smaller than the diameter of the adjusting gear, so that stable deceleration can be guaranteed.

[0047] What needs to be further explained in this embodiment is that a first swing 205 is installed on the adjusting gear 204, a first card support plate bracket 212 is fixed to the lower end of the sedimentation bar 203, a first shaft rail groove 219 is provided at the lower end of the first card support plate bracket 212, and the end of the first swing 205 away from the adjusting gear 204 is arranged in the first shaft rail groove 219, and the cooperation between the swing and the shaft rail groove and the gear belongs to a mature technology, which is not described in detail here, but simply explained that the sedimentation bar 203 uses this principle structure to achieve lifting; a first vertical limit column 210 is provided at the lower end of the sedimentation bar 203, and a first protrusion 217 is provided on the inner side of the mounting frame 211 below the card lifting bar 202, and a first vertical limit hole is provided on the first protrusion 217, and the first vertical limit column 210 slides correspondingly in the first vertical limit hole to ensure the stability of the sedimentation bar 203 when it is lifted;

[0048] The upper end of the mounting frame 211 is provided with a mounting groove, in which a second protrusion 213 and a second swing 216 are provided, and a second vertical limit hole is provided on the second protrusion 213. The lower end of the lifting strip 202 is provided with a second vertical limit column 214, and the second vertical limit column 214 is correspondingly connected to the second vertical limit hole by sliding, and the second vertical limit column 214 is a telescopic rod. The telescopic rod structure can appropriately shorten the length of the second vertical limit column 214 while achieving stable limit, so that there is no need to increase the position of the second vertical limit column 214. The thickness can also ensure the stability of the card-raising bar 202 during lifting; a second card-holding plate bracket 215 is also provided at the lower end of the card-raising bar 202, and a second shaft rail groove is provided at the lower end of the second card-holding plate bracket 215, one end of the second swing 216 is arranged in the second shaft rail groove, and the other end of the second swing 216 is connected to the adjusting gear 204. This structure is similar to the lifting structure of the sedimentation bar 203, and the implementation principle is also the same, that is, the position of the shaft rail groove is controlled by the rotation of the swing, and then the sedimentation bar 203 and the card-raising plate are driven to lift and lower through the card-holding plate bracket;

[0049] A card pulling box 301 is arranged between the card raising bar 202 and the sinking bar 203, and the card pulling belt is slidably connected in the card pulling box 301. An opening is arranged on the side of the card pulling box 301 close to the mahjong tiles, and the end of the card pulling belt close to the head box body 101 extends from the opening and is connected to a card pulling block 304, so that the mahjong tiles on the card raising bar 202 that are not in contact with the card raising bar 202 are conveniently pulled to the inclined card raising mechanism by driving the card pulling block 304 through the card pulling belt; a card suction bar 206 is arranged on the side of the sinking bar 203 away from the card raising bar 202, which is used to magnetically suck the mahjong tiles pushed onto the sinking bar 203 to a stable state. It should be noted that the adjusting gear 204 drives the lifting of the card raising bar through the second swing, so that after the card raising bar is raised to a certain height, the card pushing mechanism 201 is used to push the mahjong tiles onto the sinking bar 203, so as to avoid conflict with the card pulling box, and the second swing and the first swing 205 are respectively located on both sides of the adjusting gear 204, and there is a certain installation angle between the two. For example, when the first swing 205 is on the top, the second swing is on the bottom, so that there is a height difference between the two, so that when the synchronous action is performed, it can be level in the middle position, and then the card pushing operation is performed. It should be further noted that the principle structure of the lifting of the card raising bar is the same as the lifting principle structure of the sinking bar 203, and the difference is only the angle difference between the first swing 205 and the second swing on the adjusting gear. It should be further noted that a certain arc chamfer can be set on the side of the card pulling box close to the sinking bar 203, so that in the process of pushing the cards, the mahjong tiles on the card raising bar are more naturally vertically set on the sinking bar 203.

[0050] What needs to be further explained in the present embodiment is that the lower end of the card pushing bar 207 of the card pushing mechanism 201 is connected to a U-shaped slider 208, and the U-shaped slider 208 is connected to the pushing block 209 of the card pushing mechanism 201; the U-shaped slider 208 is provided with an opening on the side facing the card raising bar 202, which is used for slidingly connecting to the outer side of the card raising bar 202 when the card pushing bar 207 pushes cards. In this way, the width of the card pushing mechanism can be appropriately shortened, and then the opening on the card raising bar can be reduced, so that the card raising bar can be lifted and lowered more firmly and the width of the entire mahjong machine can be reduced. If the size of the original mahjong machine is retained, on the basis of reducing the width of the card pushing mechanism, more space can be reserved for the shuffling plate, and then a larger mahjong can be replaced to meet people's satisfaction of touching big cards, thereby improving the experience.

[0051] The height of the upper end surface of the sinking bar 203 in the horizontal direction is not higher than the upper end surface of the card raising bar 202, and a card suction bar 206 is provided on the side of the sinking bar 203 away from the card raising bar 202 to improve the stability of the mahjong tiles pushed onto the sinking bar 203. When the height of the upper end surface of the sinking bar 203 in the horizontal direction is equal to or similar to the height of the upper end surface of the card raising bar 202 in the horizontal direction, the mahjong tiles on the upper end surface of the card raising bar 202 can be directly pushed horizontally to the upper end surface of the sinking bar 203, and then the sinking bar 203 rises to the tabletop, so that thirteen mahjong tiles can be placed horizontally; when the height of the upper end surface of the sinking bar 203 in the horizontal direction is lower than the height of the upper end surface of the card raising bar 202 in the horizontal direction to a distance not less than the thickness of a mahjong tile, the sinking bar 203 can be lifted to the tabletop. When the mahjong tiles on the upper end of the card bar 202 are pushed to the upper end of the sinking bar 203, the mahjong tiles will be turned upside down at an angle of 90 degrees and stand on the sinking bar, so that the mahjong tiles are set upright on the sinking bar. At this time, the card suction bar 206 is also used to maintain the stability of the mahjong tiles. In this way, when the sinking bar 203 rises to the table, thirteen mahjong tiles can be directly stood up. At this time, you can grab a card by pressing the dice and play the cards directly. Both methods change the way of playing the mahjong machine and save the time of touching the cards.

[0052] What needs to be further explained in this embodiment is that the card pulling mechanism also includes a base 302, on which is provided a card transport slot 303, and the card pulling box 301 is a J-shaped structure adapted to the card pulling belt, and one end of the card pulling box 301 extends from between the card lifting bar 202 and the sinking bar 203 and is arranged on the side of the card transport slot 303 facing the middle of the mahjong machine, so as to facilitate the card pulling belt inside it to drive the mahjong from the card lifting bar to the card transport slot, and finally to the oblique card lifting mechanism; a card pulling belt motor 306 and a driving gear 305 for driving the card pulling belt to slide are arranged outside the card pulling box 301, and the card pulling belt motor 306 is connected with the driving gear 305 in transmission to drive the operation of the driving gear 305.
