Description

Technical Field

[0001] The utility model relates to the field of mahjong machines, in particular to a rotary-wing automatic mahjong machine. Background Art

[0002] The rotary-wing automatic mahjong machine has only become popular in recent years. Its working principle is that after the big plate is shuffled, the card suction device transports the mahjong tiles to the machine head for stacking. The stacked mahjong tiles are pushed into the spiral card storage slot. The pusher pushes the mahjong tiles to the card lifting board driven by the turntable assembly. The process of the mahjong tiles rising is a spiral rise. When all the mahjong tiles are on the card lifting board, the card lifting board rises and lifts the mahjong tiles to the mahjong machine table. At present, most of the technologies use one motor for stacking the tiles on the machine head, one motor for rotating the pusher, and one motor for lifting the card lifting board. After sucking the tiles, three motors are needed to complete the card lifting action in one direction, such as the card loading mechanism of the fully automatic mahjong machine with application number 201720084625.X.

[0003] At the same time, the existing technology also combines the power source of the card pushing rod and the power source of the card raising plate into one, and uses one motor to complete the actions of the card pushing rod and the card raising plate. For example, a fully automatic mahjong machine with application number 202010940703.8 still requires one motor to stack cards on the head of the machine, and two motors are still required to complete the card raising action in one direction after sucking the cards. The cost is still relatively high, there are many components, and the structure is relatively bloated. Utility Model Content

[0059] The following is combined with Figure 1-13 The utility model is further described in detail with examples.

[0060] Example 1

[0061] The rotary-wing automatic mahjong machine comprises a card storage rack 10, a card raising plate 11, a connecting rod assembly 12, a card stacking mechanism 13, a card pushing mechanism 14 and a motor 15; one end of the card raising plate 11 is hinged on the card storage rack 10, and the other end thereof is connected to the connecting rod assembly 12, and the movement of the connecting rod assembly 12 can drive the other end of the card raising plate 11 to rise and fall. The card pushing mechanism 14 comprises a turntable assembly 141 and a first card pushing rod 142 installed on the turntable assembly 141, and the card pushing mechanism 14 is connected to the card raising plate 11 through the connecting rod assembly 12, and the turntable assembly 141 rotates to drive the connecting rod assembly 12 to move, and the connecting rod assembly 12 drives the card raising plate 11 to rise and fall;

[0062] The motor 15 is connected to the stacking mechanism 13 and the card pushing mechanism 14 at the same time, that is, the motor 15 is used as the driving source of the stacking mechanism 13 and the card pushing mechanism 14 at the same time. When the motor 15 rotates in one direction, that is, when the motor 15 rotates counterclockwise, the active gear A 16 on the motor 15 is meshed with the driven gear 131 on the stacking mechanism 13 for transmission, and the active gear B 17 is idle at this time. The stacking mechanism 13 is used to stack cards and push the mahjong cards into the card storage slot 101 of the card storage rack 10;

[0063] When the motor 15 rotates in the other direction, that is, when the motor 15 rotates clockwise, the active B gear 17 on the motor 15 is meshed with the turntable assembly 141 for transmission, and the turntable assembly 141 drives the card-raising plate 11 to rise and fall through the connecting rod assembly 12. At the same time, the turntable assembly 141 drives the first card-pushing rod 142 to push the mahjong cards in the card storage slot 101 onto the card-raising plate 11. At this time, the active A gear 16 is idling.

[0064] A sleeve 18 is fixed on the output shaft of the motor 15. The sleeve 18 is radially limited on the output shaft of the motor 15. A stopper 181 is provided on the outer circumferential wall of the sleeve 18. The stopper 181 separates the sleeve 18 into an upper sleeve 18a and a lower sleeve 18b. The driving A gear 16 rotates unidirectionally on the lower sleeve 18b, and the lower sleeve 18b drives the driving A gear 16 to rotate synchronously, and the driving B gear 17 rotates idly on the upper sleeve 18a; the driving B gear 17 rotates unidirectionally on the upper sleeve 18a, and the upper sleeve 18a drives the driving B gear 17 to rotate synchronously, and the driving A gear 16 rotates idly on the lower sleeve 18b.

[0065] The outer circumferential surfaces of the lower sleeve 18b and the upper sleeve 18a are both provided with open grooves 182, and the opening directions of the open grooves 182 at the upper and lower ends are opposite; the active gear A 16 and the active gear B 17 are both installed with magnetic steel, and the magnetic steel will be magnetically attracted to the output shaft of the motor 15 through the sleeve. When the motor 15 drives the sleeve 18 to rotate, the magnetic steel on the active gear A 16 or the active gear B 17 is limited by the open groove 182 at the corresponding end and rotates synchronously with the sleeve 18. When the open groove 182 at the corresponding end is limited by the magnetic steel, the sleeve 18 will drive the gear on the end to rotate synchronously. Traditional unidirectional rotation is basically achieved through one-way bearings, which requires two one-way bearings to respectively realize the rotation of the active gear A 16 and the active gear B 17, which will increase the cost. The sleeve and the magnetic steel can realize the unidirectional rotation of the two gears, with a simple structure and low cost. However, in other embodiments, it can also be achieved through two one-way bearings.

[0066] The inner wall of the shaft hole of the active gear A 16 and the active gear B 17 is provided with a second mounting groove, and the magnetic steel is installed in the second mounting groove, and the open end of the opening groove 182 is connected to the outer circumferential surface of the sleeve 18 through the arc surface 1821. The design of the arc surface 1821 allows the gear to run more smoothly when idling, and the magnetic steel can also smoothly enter the opening groove 182 and limit with it, so as to realize synchronous transmission.

[0067] The stacking mechanism is used to stack mahjong tiles together and push the mahjong tiles into the card storage slot 101. The stacking mechanism includes a stacking wheel 132, a driven gear 131, a card holder 133 and a second card pusher 134. The card holder 133 is used to place mahjong tiles. The inner end of the second card pusher 134 is hinged to the card storage rack 10 through a pin. At the same time, the second card pusher 134 is also equipped with a tension spring to connect it to the card storage rack 10. The setting of the tension spring facilitates the instant reset of the second card pusher 134. The driven gear 131 is fixed to the upper end of the stacking wheel 132 and rotates synchronously with it. In this embodiment, the driven gear 131 is integrally formed at the upper end of the stacking wheel 132, and the driven gear 131 is meshed with the active A gear 16;

[0068] The stacking wheel 132 is provided with a first track 1321, which is a grooved annular track. The stacking wheel 132 is connected to the card receiving seat 133 through the first track 1321. The stacking wheel 132 rotates and drives the card receiving seat 133 to rise and fall.

A guide lifting hole 103 arranged vertically and penetrating to the inside is provided on the side of the first installation slot 102. A first roller 136 is installed at the inner end of the card receiving seat 133. The first roller 136 extends into the first track 1321 through the guide lifting hole 103. When the card stacking wheel 132 rotates, the first roller 136 moves along the first track 1321, thereby driving the card receiving seat 133 to rise and fall along the guide lifting hole 103.

[0071] A support plate 137 is installed at the outer bottom of the first mounting groove 102, and at least one guide rod 138 is installed at the end of the support plate 137.
