Description

Technical Field

[0001] The utility model belongs to the technical field of mahjong machines and relates to a suction card wheel transmission mechanism of a mahjong machine. Background Art

[0002] The suction card wheel of a mahjong machine is an important component of the automatic mahjong machine's card suction and delivery mechanism, which is used to pick up the shuffled cards from the shuffling tray, deliver the picked-up cards to the entrance of the mahjong card conveying channel, and then send the cards to the stacking card mechanism through the delivery belt for stacking card operations. Between the suction card wheel of the mahjong machine and the stacking card mechanism, it is necessary to cooperate with a transmission structure through a delivery conveying mechanism to convey the cards. Most of the existing conveying structures use two card delivery rollers to cooperate with the suction card wheel to deliver the cards. Generally, there is a difference in the rotation speeds between the two card delivery rollers. When the speed difference is large, the cards are prone to slipping. At the same time, during the card delivery process, the cards are prone to getting stuck at the gap between the card delivery roller and the suction card wheel, making it difficult to smoothly and safely send out the cards, and the smoothness of the conveying is relatively average. Therefore, there is an urgent need to design a suction card wheel transmission mechanism for a mahjong machine that can overcome the above defects.

[0003] In order to overcome the deficiencies of the prior art, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a mahjong machine and its suction card wheel and card picking and conveying mechanism [Application No.: 202321713504.9], which includes a conveying bracket, and a suction card wheel is provided on the conveying bracket above the shuffling large tray; the shuffling large tray is driven by a shuffling motor to rotate, and a first transmission component is provided between the suction card wheel and the shuffling large tray for obtaining power from the shuffling large tray and transmitting it to the suction card wheel; several rollers arranged side by side with the suction card wheel and having the same rotation direction are also provided on the conveying bracket, the top sides of all the rollers form a conveying platform, and a second transmission component for obtaining power from the suction card wheel and transmitting it to each roller is provided between the roller and the suction card wheel and between adjacent rollers.

Specific implementation mode

[0025] The present utility model will be further described below in conjunction with the accompanying drawings.

[0026] As Figures 1-4 shown, a card suction wheel transmission mechanism of a mahjong machine includes a fixed frame 1, a rotatable card suction wheel 2 is provided on the fixed frame 1, a middle-position transmission fixed bracket 3 is provided on the fixed frame 1, an active transmission gear 4 is provided on the card suction wheel 2, a first card-sending roller structure 5 and a second card-sending roller structure 6 which are rotatable and staggered with each other are provided on the middle-position transmission fixed bracket 3, the first card-sending roller structure 5 and the second card-sending roller structure 6 are meshed and cooperated with the active transmission gear 4 through a same-speed transmission assembly 7, the horizontal height of the second card-sending roller structure 6 is higher than the horizontal height of the first card-sending roller structure 5, a card-placement middle inheritance support part 8 is provided on the middle-position transmission fixed bracket 3, and the card-placement middle inheritance support part 8 is located between the first card-sending roller structure 5 and the card suction wheel 2.

[0027] In this embodiment, the card suction wheel 2 is driven by a motor 100 located behind the fixed frame 1. When the mahjong cards are placed into the shuffling tray, the cards are sent to the card suction wheel 2 one by one through centrifugal force and hanging strips, and the cards are fixed on the surface of the card suction wheel 2 by magnetic force. After the card suction wheel 2 rotates, it will drive the cards to the card-placement middle inheritance support part 8. After the cards pass through the card-placement middle inheritance support part 8, they enter the first card-sending roller structure 5. During the rotation of the card suction wheel 2, it will synchronously drive the active transmission gear 4 to rotate. Through the meshing and cooperation between the active transmission gear 4 and the same-speed transmission assembly 7, the first card-sending roller structure 5 and the second card-sending roller structure 6 are synchronously driven to rotate. The same-speed transmission assembly 7 can ensure that the first card-sending roller structure 5 and the second card-sending roller structure 6 have the same rotation speed. Cooperating with the card-placement middle inheritance support part 8 can prevent the cards from jamming at the gap between the card suction wheel 2 and the first card-sending roller structure 5, and smoothly and safely send out the cards to ensure the smoothness of card delivery.

[0028] Combined with Figures 1-4As shown, the same-pace transmission assembly 7 includes a first driven gear 9 and a second driven gear 10 disposed on the mid-mounted transmission fixed bracket 3. The driving transmission gear 4 and the first code-sending roller structure 5 are respectively meshed and cooperated with the first driven gear 9. The first code-sending roller structure 5 and the second code-sending roller structure 6 are respectively meshed and cooperated with the second driven gear 10. The diameters of the first driven gear 9 and the second driven gear 10 are the same.

[0029] Specifically, when the card-sucking wheel 2 rotates, it synchronously drives the driving transmission gear 4 to rotate. At this time, the driving transmission gear 4 is meshed and cooperated with the first driven gear 9, which can drive the first driven gear 9 to rotate synchronously. Then, through the meshing and cooperation between the first driven gear 9 and the first code-sending roller structure 5, the first code-sending roller structure 5 is driven to rotate. The first code-sending roller structure 5 is meshed and cooperated with the second driven gear 10, driving the second driven gear 10 to rotate. Then, through the meshing and cooperation between the second driven gear 10 and the second code-sending roller structure 6, the second code-sending roller structure 6 is driven to rotate. The diameters of the first driven gear 9 and the second driven gear 10 are the same, and the speed ratios are the same. During the transmission process, it is ensured that the rotation speeds of the first code-sending roller structure 5 and the second code-sending roller structure 6 are the same, avoiding the speed difference between the first code-sending roller structure 5 and the second code-sending roller structure 6, achieving the purpose of smoothly and safely sending out the coded cards, and avoiding the situation of the coded cards slipping.

[0030] Combined Figure 1 、 Figure 2 As shown, the first driven gear 9 and the second driven gear 10 are respectively connected to the mid-mounted transmission fixed bracket 3 through rotating shafts. The diameter of the driving transmission gear 4 is larger than that of the first driven gear 9.

[0031] In this embodiment, the diameter of the driving transmission gear 4 is larger than that of the first driven gear 9. The large-diameter gear drives the small-diameter gear to rotate, achieving an accelerating effect.

[0032] The middle card-supporting part 8 of the coded cards includes a middle card-supporting table board 11 disposed on the mid-mounted transmission fixed bracket 3. The middle card-supporting table board 11 is located between the first code-sending roller structure 5 and the card-sucking wheel 2. The horizontal height of the middle card-supporting table board 11 is higher than the horizontal height of the first code-sending roller structure 5.

[0033] In this embodiment, when the coded tiles are sent from the tile suction wheel 2 to the first coded tile transfer roller structure 5, the coded tiles will first pass through the inherited supporting plate 11 of the coded tiles. The inherited supporting plate 11 of the coded tiles is located between the first coded tile transfer roller structure 5 and the tile suction wheel 2, which can prevent the coded tiles from jamming in the gap between the tile suction wheel 2 and the first coded tile transfer roller structure 5, and smoothly and safely send out the coded tiles to ensure the smoothness of the coded tile conveyance. The horizontal height of the inherited supporting plate 11 of the coded tiles is higher than the horizontal height of the first coded tile transfer roller structure 5, which can prevent the coded tiles from colliding and rebounding with the first coded tile transfer roller structure 5 when going out from the inherited supporting plate 11 of the coded tiles and ensure the accuracy of tile delivery.

[0034] As shown in Figure 2 Fig. 5, the first coded tile transfer roller structure 5 includes a first tile playing roller 12 and a first roller tooth 13. The first tile playing roller 12 and the first roller tooth 13 are integrally formed. The first driven gear 9 and the second driven gear 10 are respectively meshed and cooperated with the first roller tooth 13. The second coded tile transfer roller structure 6 includes a second tile playing roller 14 and a second roller tooth 15. The second roller tooth 15 is meshed and cooperated with the second driven gear 10.

[0035] In this embodiment, during the transmission process, the transmission direction is that the driving transmission gear 4 drives the first driven gear 9 to rotate, the first driven gear 9 drives the first roller tooth 13 and the first tile playing roller 12 to rotate, the first roller tooth 13 drives the second driven gear 10 to rotate, and the second driven gear 10 drives the second roller tooth 15 and the second tile playing roller 14 to rotate.

[0036] Rubber sleeves are sleeved on the first tile playing roller 12 and the second tile playing roller 14.

[0037] In this embodiment, the rubber sleeves can increase the friction force of the contact surfaces between the first tile playing roller 12 and the second tile playing roller 14 and the coded tiles to ensure smooth tile delivery.

[0038] As shown in Figures 2-3 Fig. 9, a plurality of adsorption areas 16 and arc transition areas 17 are evenly distributed in the circumferential direction of the tile suction wheel 2. The adsorption areas 16 and the arc transition areas 17 are arranged alternately. The adsorption areas 16 are internally embedded with tile suction magnets.

[0039] In this embodiment, the adsorption areas 16 cooperate with the tile suction magnets to adsorb the mahjong coded tiles for convenient tile placement, and the arc transition areas 17 can avoid interference with the first tile playing roller 12.

[0040] As shown in Figure 1 、 Figure 4 Fig. 9, a front fixing bracket 18 is sleeved on the front end of the fixed frame 1. The middle transmission fixing bracket 3 is located between the fixed frame 1 and the front fixing bracket 18. A transmission installation area 19 is opened inside the front fixing bracket 18.

[0041] In this embodiment, on the one hand, the front fixing bracket 18 can assist in fixing the center drive fixing bracket 3, and on the other hand, by setting the drive installation area 19, it is convenient to position and install the driving transmission gear 4, the first driven gear 9, the first roller tooth 13, the second driven gear 10, and the second roller tooth 15.

[0042] Combined with Figure 1 As shown, a card feeding channel 20 is formed among the fixed frame 1, the front fixing bracket 18, the first card discharging roller 12, and the second card discharging roller 14.

[0043] In this embodiment, the card feeding channel 20 is used to feed the mahjong tiles along the travel of the card feeding channel 20.

[0044] The working principle of the present utility model is:

[0045] The card suction wheel 2 is driven by a motor located behind the fixed frame 1. When the mahjong tiles enter the shuffling tray, the tiles are sent to the card suction wheel 2 one by one through centrifugal force and hanging strips, and the tiles are fixed on the surface of the card suction wheel 2 by magnetic force. After the card suction wheel 2 rotates, it will drive the tiles to the receiving tray 11 in the card inheritance area. After passing through the receiving tray 11 in the card inheritance area, the tiles enter the first card feeding roller structure 5. When the card suction wheel 2 rotates, it synchronously drives the driving transmission gear 4 to rotate. At this time, the driving transmission gear 4 meshes with the first driven gear 9, which can drive the first driven gear 9 to rotate synchronously. Then, through the meshing between the first driven gear 9 and the first card feeding roller structure 5, the first card feeding roller structure 5 is driven to rotate. The first card feeding roller structure 5 meshes with the second driven gear 10, driving the second driven gear 10 to rotate. Then, through the meshing between the second driven gear 10 and the second card feeding roller structure 6, the second card feeding roller structure 6 is driven to rotate. The diameters of the first driven gear 9 and the second driven gear 10 are the same, and the speed ratios are the same. During the transmission process, it is ensured that the rotational speeds of the first card feeding roller structure 5 and the second card feeding roller structure 6 are the same, avoiding the speed difference between the first card feeding roller structure 5 and the second card feeding roller structure 6, achieving the purpose of smoothly and safely sending out the tiles and avoiding the situation of tile slipping.

[0046] The diameter of the driving transmission gear 4 is larger than that of the first driven gear 9. The large-diameter gear drives the small-diameter gear to rotate, achieving an accelerating effect.

[0047] The horizontal height of the receiving tray 11 in the card inheritance area is higher than that of the first card feeding roller structure 5, avoiding the collision and rebound of the tiles with the first card feeding roller structure 5 when the tiles go out from the receiving tray 11 in the card inheritance area and ensuring the accuracy of card feeding.

[0048] During the transmission process, the transmission direction is that the driving transmission gear 4 drives the first driven gear 9 to rotate, the first driven gear 9 drives the first roller tooth 13 and the first card - sending roller 12 to rotate, the first roller tooth 13 drives the second driven gear 10 to rotate, and the second driven gear 10 drives the second roller tooth 15 and the second card - sending roller 14 to rotate. The rubber sleeve can increase the friction force of the contact surface between the first card - sending roller 12 and the second card - sending roller 14 and the card stacking, ensuring smooth card feeding.

[0049] The adsorption area 16 cooperates with the card - sucking magnet to adsorb the mahjong cards for stacking, which is convenient for card feeding. The arc - shaped transition area 17 can avoid interference with the first card - sending roller 12.

[0050] The front fixing bracket 18 can, on the one hand, play an auxiliary fixing role for the middle - positioned transmission fixing bracket 3, and on the other hand, by setting the transmission installation area 19, it is convenient to position and install the driving transmission gear 4, the first driven gear 9, the first roller tooth 13, the second driven gear 10, and the second roller tooth 15. The card - feeding channel 20 is used to feed the mahjong cards along the travel of the card - feeding channel 20.

Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to substitute them, but will not deviate from the spirit of the present utility model.

[0052] Although terms such as fixed frame 1, card - sucking wheel 2, middle - positioned transmission fixing bracket 3, driving transmission gear 4, first card - sending roller structure 5, second card - sending roller structure 6, same - speed transmission component 7, card - stacking intermediate supporting part 8, first driven gear 9, second driven gear 10, card - stacking intermediate supporting table board 11, first card - sending roller 12, first roller tooth 13, second card - sending roller 14, second roller tooth 15, adsorption area 16, arc - shaped transition area 17, front fixing bracket 18, transmission installation area 19, card - feeding channel 20, motor 100, etc. are used more frequently in this article, the possibility of using other terms is not excluded. Using these terms is only to more conveniently describe and explain the essence of the present utility model, and interpreting them as any additional limitation is contrary to the spirit of the present utility model.
