Mahjong machine card distributing mechanism

Abstract

This utility model discloses a mahjong machine card-loading mechanism, relating to the field of mahjong machine technology. It includes a track assembly with a card-pushing component and a card-lifting component mounted on it. Through the arrangement of the card-pushing and card-lifting components, a swing wheel drives the card-pushing arm to rotate, and the rotation of the card-pushing gear also drives the second support plate to rotate. Due to the arrangement of the low and high slots, the transmission shaft slides simultaneously. When the transmission shaft slides, it can open or close the card-lifting plate. During card loading, the transmission shaft opens one side of the card-lifting plate, and the swing wheel drives the card-pushing arm to push the mahjong tile through the mahjong tile movement slot to the top of the card-lifting plate. Then, the second support plate drives the transmission shaft to slide back to its initial position, closing one side of the card-lifting plate, thus completing the card loading. The entire card loading process allows the mahjong tiles to slide onto the table in a continuous, flowing motion, easily achieving a reasonable mahjong tile arrangement without manual pushing, making it highly practical.

A second support plate 302 is rotatably disposed on the top of the card-lifting gear fixing plate 301. A card-lifting gear 313 is integrally formed on the top of the second support plate 302, and the card-lifting gear 313 meshes with the card-pushing gear 202. An arc-shaped low groove 315 and a high groove 316 are integrally formed on both sides of the bottom end of the second support plate 302, and the two ends of the low groove 315 are respectively connected to the two ends of the high groove 316.

A rack and pinion sliding rail 303 is fixedly installed at the bottom of the housing 101 near the bottom of the lifting plate groove 104. A drive shaft 304 is provided between the second support plate 302 and the lifting plate gear fixing plate 301. One end of the drive shaft 304 extends into the groove of the rack and pinion sliding rail 303. The sliding groove at the top of the rack and pinion sliding rail 303 is adapted to the drive shaft 304, and the top of the drive shaft 304 near the end of the rack and pinion sliding rail 303 is provided with serrations.

[0038] A rocker arm gear fixing seat 306 is fixedly installed through the inner wall of the lifting slot 104 near the rack sliding rail 303, and a drive shaft 304 is rotatably installed on the rocker arm gear fixing seat 306. A rocker arm gear 310 is fixedly installed at one end of the drive shaft 304 near the rack sliding rail 303, and the rocker arm gear 310 is meshed with the sawtooth on the drive shaft 304. A lifting rocker arm 305 is fixedly installed at the other end of the drive shaft 304. A drive shaft bearing 312 is fixedly installed at the top end of the drive shaft 304 near the second support plate 302, and the drive shaft bearing 312 is compatible with both the low slot 315 and the high slot 316. A signal magnet 314 is inlaid and installed on the top edge of the second support plate 302, and the input end of the Hall element 110 extends to the top of the second support plate 302 and is aligned with the signal magnet 314. A lifting plate 311 adapted to the lifting plate slot 104 is provided at the opening of the lifting plate slot 104.

A rocker arm adapted to the side groove 308 is fixedly installed at the top of the side of the lifting rocker arm 305 near the support block 307. Bearing 309, through the arrangement of the pusher assembly 2 and the lifter assembly 3, enables the motor 205 to drive the drive gear 204 to rotate when the required number of mahjong tiles have been pushed into the track from all four sides. The drive gear 204 drives the pusher gear 202, the first support plate 201, and the upper bracket 207 to rotate. The first support plate 201 drives the swing wheel 208 to rotate. Due to the arrangement of the swing wheel groove 105, the swing wheel 208 will rotate according to the shape of the swing wheel groove 105. The swing wheel 208 drives the pusher arm 206 to rotate. The rotation of the pusher gear 202 will also drive the second support plate 302 to rotate. Due to the low groove 315 and the high groove 316... The setting will simultaneously drive the drive shaft 304 to slide. When the drive shaft 304 slides, it can drive the lifting plate 311 to open or close. When placing a tile, the drive shaft 304 drives one side of the lifting plate 311 to open, and the swing wheel 208 drives the pusher arm 206 to push the mahjong tile through the mahjong moving groove 102 to the top of the lifting plate 311. Then, the second support plate 302 drives the drive shaft 304 to slide back to the initial position, driving one side of the lifting plate 311 to close, thus completing the placement of the tile. The entire tile placement process allows the mahjong tile to slide onto the table in a dragon-like manner, which can easily achieve reasonable placement of the mahjong tile without the need for manual pushing of the mahjong tile, making it highly practical.

[0039] Working principle of this utility model:

[0040] During the shuffling process of the mahjong machine, after all four sides have completed their tasks and the required number of mahjong tiles are pushed into the mahjong moving slot 102, all motors stop, and the mahjong tiles are stored in the mahjong moving slot 102. The mahjong machine then enters the waiting state for tile lifting. At this time, the tile pushing arm 206 stops behind the tile lifting plate 311, the signal magnet 314 on the second support plate 302 is aligned with the Hall element 110, and the sliding bearing 211 on the balance wheel 208 is in section A of the balance wheel slot 105 (e.g., Figure 3 As shown, A, B, C, D, E, F, and G represent different positions within the balance wheel groove 105 (to facilitate indicating the position of the sliding bearing 211). The transmission shaft bearing 312 on the transmission shaft 304 is located at position a in the high-position groove 316 (e.g., ...). Figure 13 As shown, a, b, c, and d represent the various positions of the low-position slot 315 and the high-position slot 316, respectively, to facilitate the indication of the position of the transmission shaft bearing 312.

[0041] After the card-raising command is issued, motor 205 rotates, driving drive gear 204 to rotate, and push gear 202 rotates counterclockwise. Balance wheel 208 and push arm 206 rotate around shaft 203 with push gear 202. Sliding bearing 211 on balance wheel 208 leaves section A of balance wheel groove 105 and enters section B. Driven by section B of balance wheel groove 105, balance wheel 208 rotates counterclockwise relative to push gear 202 around balance wheel shaft 209. Balance wheel 208 drives push arm 206 to rotate clockwise relative to push gear 202. The combined rotational speed of push arm 206 around push gear 202 is slower than that of push gear 202. At the same time, the lifting gear 313 rotates, and the transmission shaft bearing 312 at the right end of the transmission shaft 304 leaves section a and enters section b of the lifting gear. The transmission shaft bearing 312 drives the transmission shaft 304 to move closer to the second support plate 302. The rocker arm gear 310 rotates clockwise, the lifting rocker arm 305 rotates clockwise, and the lifting plate 311 rotates clockwise around the lifting plate shaft 109. The right end of the lifting plate 311 descends. When the lifting gear 313 rotates to the right end of section b, the right end of the lifting plate 311 descends to its position. At the same time, the pushing gear 202 rotates with the swing wheel 208 and the pushing arm 206 to the sliding bearing 211 on the swing wheel 208, which reaches the end of section B of the swing wheel groove 105.

[0042] The pusher gear 202 continues to rotate, and the balance wheel 208 and the pusher arm 206 rotate around the axis of the pusher gear 202 with the pusher gear 202. The sliding bearing 211 on the balance wheel 208 leaves section B of the balance wheel groove 105 and enters section C of the balance wheel groove 105. Section C is an arc-shaped groove concentric with the axis of the pusher gear 202. The balance wheel 208 does not rotate relative to the pusher gear 202 around the balance wheel axis 209. The balance wheel 208 does not drive the pusher arm 206 to rotate relative to the axis of the pusher gear 202. The speed of the pusher arm 206 rotating around the axis of the pusher gear 202 is the same as that of the pusher gear 202. At the same time, the transmission shaft bearing 312 at the right end of the transmission shaft 304 enters section d of the groove of the lifting gear 313. The transmission shaft bearing 312 remains stationary, and the lifting plate 311 remains stationary in the low position.

[0043] As the card-pushing gear 202 continues to rotate, the balance wheel 208 and the card-pushing arm 206 rotate around the axis of the card-pushing gear 202. The sliding bearing 211 on the balance wheel 208 leaves section C of the balance wheel groove 105 and enters section D of the balance wheel groove 105. Driven by the balance wheel groove 105 in section D, the balance wheel 208 rotates clockwise relative to the card-pushing gear 202 around the balance wheel axis 209. The balance wheel 208 drives the card-pushing arm 206 to rotate counterclockwise relative to the card-pushing gear 202. The two rotational speeds... After stacking, the speed of the pusher arm 206 rotating around the pusher gear 202 is faster than that of the pusher gear 202. When the pusher arm 206 touches the mahjong tile in the mahjong moving groove 102, the pusher arm 206 pushes the mahjong tile forward. The mahjong tile moves along the mahjong moving groove 102 and the lifting plate 311 towards the table. At the same time, the transmission shaft bearing 312 at the right end of the transmission shaft 304 is in the d section of the groove of the lifting gear 313. The transmission shaft bearing 312 remains stationary, and the lifting plate 311 remains stationary in the low position.

[0044] The pusher gear 202 continues to rotate, and the balance wheel 208 and the pusher arm 206 rotate around the axis of the pusher gear 202. The pusher arm 206 pushes the mahjong tiles forward, and the mahjong tiles move towards the table along the mahjong moving groove 102 and the lifting plate 311. The sliding bearing 211 on the balance wheel 208 leaves section D of the balance wheel groove 105 and enters section E of the balance wheel groove 105. Section E is an arc-shaped groove concentric with the axis of the pusher gear 202. The balance wheel 208 does not rotate relative to the pusher gear 202 around the balance wheel axis 209. The balance wheel 208 does not drive the pusher arm 206 to rotate relative to the axis of the pusher gear 202. The rotation speed of the pusher arm 206 around the axis of the pusher gear 202 is the same as that of the pusher gear 202. At the same time, the transmission shaft bearing 312 is in section d of the groove of the second support plate 302. The transmission shaft bearing 312 remains stationary, and the lifting plate 311 remains stationary in a low position.

[0045] The pusher gear 202 continues to rotate, and the balance wheel 208 and the pusher arm 206 rotate around the shaft 203 with the pusher gear 202. The pusher arm 206 pushes the mahjong tiles forward, and the mahjong tiles move towards the table along the mahjong moving groove 102 and the lifting plate 311. When the sliding bearing 211 on the balance wheel 208 reaches the end of section E of the balance wheel groove 105, all the mahjong tiles in the mahjong moving groove 102 have left the mahjong moving groove 102. Some of them reach the table and some are on the lifting plate 311. At the same time, the transmission shaft bearing 312 reaches the end of section d of the groove of the lifting gear 313.

[0046] The pusher gear 202 continues to rotate, and the balance wheel 208 and the pusher arm 206 rotate around the shaft 203 with the pusher gear 202. The sliding bearing 211 leaves section E of the balance wheel groove 105 and enters section F of the balance wheel groove 105. Driven by the balance wheel groove 105 in section F, the balance wheel 208 rotates clockwise relative to the pusher gear 202 around the balance wheel shaft 209. The balance wheel 208 drives the pusher arm 206 to rotate counterclockwise relative to the pusher gear 202. The rotational speed of the pusher arm 206 is equal to that of the pusher gear 202 but in the opposite direction. After the two speeds are superimposed, the pusher arm 206 stops rotating and remains stationary relative to the track. At the same time, the lifting gear 313... Rotation causes the drive shaft bearing 312 to leave section d and enter section c. The drive shaft bearing 312 drives the drive shaft 304 to move away from the second support plate 302. The rocker arm gear 310 reverses, the tile-lifting rocker arm 305 reverses, and the tile-lifting plate 311 reverses around the tile-lifting plate shaft 109. The right end of the tile-lifting plate 311 rises, and the mahjong tiles on the tile-lifting plate 311 rise together with the tile-lifting plate 311. When the tile-lifting gear 313 rotates to the point where the drive shaft bearing 312 reaches the end of section c, the right end of the tile-lifting plate 311 rises to its position, and all the mahjong tiles have reached the surface of the table. At the same time, the push gear 202 drives the swing wheel 208 to rotate to the point where the sliding bearing 211 reaches the end of section F of the swing wheel groove 105.

[0047] The pusher gear 202 continues to rotate, and the balance wheel 208 rotates around the axis of the pusher gear 202 along with the pusher gear 202. The sliding bearing 211 leaves the F segment of the balance wheel groove 105 and enters the G segment of the balance wheel groove 105. Driven by the balance wheel groove 105 in the G segment, the balance wheel rotates clockwise relative to the pusher gear 202 around the balance wheel shaft hole. The balance wheel 208 drives the pusher arm 206 to rotate counterclockwise relative to the pusher gear 202. After the two speeds are superimposed, the speed of the pusher arm 206 rotating around the axis of the pusher gear 202 is faster than that of the pusher gear 202. At the same time, the lifting gear 313 rotates, and the transmission shaft bearing 312 leaves the c segment and enters the a segment. The transmission shaft bearing 312 remains stationary, and the lifting plate 311 remains stationary in the high position.

[0048] The pusher gear 202 continues to rotate, and the balance wheel 208 and pusher arm 206 rotate around the shaft 203 with the pusher gear 202. The sliding bearing 211 leaves the G section of the balance wheel groove 105 and enters the A section of the balance wheel groove 105.
