Description

Technical Field

[0001] The present invention relates to the technical field of automatic mahjong machines, and particularly relates to a high-stability card-pushing mechanism for a mahjong machine. Background Art

[0002] Mahjong is a traditional mass entertainment and leisure activity. For existing automatic mahjong machines, after picking up and stacking the magnetic mahjong tiles in the shuffling tray (basically stacked in two layers), the adopted card-pushing mechanism is used to push the mahjong tiles to a specified position, and finally, they are sent to the mahjong table through a lifting rack for players to play.

[0003] Existing automatic mahjong machines use a single motor drive to achieve two actions of card-pushing and card-lifting. Among them, the mechanism for card-pushing usually uses a single-arm drive, so a fixed block or a horizontal sliding rod is required to cooperate to ensure the parallel and stable horizontal movement of the push plate. The adopted card-pushing component also uses a fixed block and a push plate to cooperate for the card-pushing action. This structure has poor stability, the single arm bears a large force, occupies a large space during installation, and incurs high costs. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcoming of poor structural stability of the card-pushing mechanism in the prior art, and to propose a high-stability card-pushing mechanism for a mahjong machine and its usage method.

By setting the first driving motor, power can be provided for the transmission wheel, thereby driving the cyclic movement of the first connecting rod and the second connecting rod.

[0007] Preferably, the card pushing transmission assembly includes a second driving motor, a driving gear set is connected to one end of the second driving motor, the driving gear set includes a first driving wheel, a second driving wheel is provided on one side of the first driving wheel, a first driven wheel is provided on one side of the first driving wheel, a second driven wheel is provided on one side of the second driving wheel, a cam transmission member is connected to one end of the second driving wheel, and a fixed housing is provided outside the cam transmission member. By connecting the second driving wheel and the cam transmission member, the power of the second driving motor is transmitted, so that the large swing arm can swing back and forth.

[0008] Preferably, one side of the large swing arm is connected to the cam transmission member, one end of the top of the large swing arm is connected to a second card pushing plate, limiting plates are provided on both sides of the second card pushing plate, and the limiting plates are connected to the installation main body. By setting the limiting plates, when the card pushing transmission assembly is not in use, the second card pushing plate can be supported to prevent it from falling down.

[0009] Preferably, a first rocker is connected to one side of the first driven wheel, a second rocker is connected to one side of the second driven wheel, the first rocker and the second rocker are jointly connected to a transmission plate, and the transmission plate is connected to a card supporting plate. By connecting the first rocker and the second rocker to the transmission plate, it is convenient to drive the card supporting plate to move cyclically through the transmission plate.

[0010] Preferably, the lifting transmission assembly includes a fixed seat, a telescopic rod is installed at one end of the fixed seat, one end of the telescopic rod is connected to the card supporting plate, and the number of the fixed seat and the telescopic rod is two groups and they are installed on both sides of the driving gear set. By setting the telescopic rod, it is convenient for the card pushing plate to move up and down.

[0011] Preferably, the magnetic control sensing assembly includes a height magnetic control component and a head magnetic control component, the height magnetic control component is connected to the second driven wheel, and the head magnetic control component is installed on one side of the fixed frame. By setting the height magnetic control component, it is convenient to control the highest point position of the card stacking of the mahjong tiles.

[0012] Preferably, both the large swing arm and the support seat are made of POM plastic raw material. The POM plastic raw material has the characteristics of high hardness, high rigidity and high wear resistance. Using the POM plastic raw material can improve the service life of the large swing arm.

[0013] Preferably, the adjusting member includes a slider, on which there is a movable sliding groove, on which there are fixed bolt holes, and one side of the slider is connected with an adjusting plate. Mahjong tiles on the current market have different volumes, and the lengths of stacks of mahjong tiles of different sizes are different. By setting the adjusting member, fine-tuning can be done according to the length of stacks of mahjong tiles of different sizes, which is convenient for stacking and placing mahjong tiles.

[0014] Preferably, first, the card-pushing mechanism is installed inside the mahjong table through the installation holes. Mahjong tiles on the current market have different volumes, and the lengths of stacks of mahjong tiles of different sizes are different. Fine-tuning needs to be done according to different specifications of mahjong tiles. The operator first pulls the adjusting plate out slightly with his hand to increase the partial length of the card-placement plate. The distance can be adjusted according to the actual stacking length of mahjong tiles. The adjustment range is limited by the limit sliding groove. After adjusting to the appropriate position, pass the fixing bolt through the limit sliding groove and connect it with the fixed bolt hole to complete the fixing.

[0015] Second, start the first driving motor to drive the transmission wheel. The transmission wheel transmits the power to the first connecting rod and the second connecting rod. The first connecting rod drives the card-receiving plate to move upward, lifting the mahjong tiles to a position parallel to the card-placement plate. The mahjong tiles enter through the card-inlet of the card-inlet plate and are placed on the fixed opening of the card-receiving plate. When receiving the first card, the card-receiving plate drops. When receiving the second card, the second connecting rod drives the first card-pushing plate to swing, pushing the mahjong tile onto the card-placement plate. Two cards stacked together form a group, and so on in a cycle. The accuracy of the lifting and lowering of the card-receiving plate and the pushing distance of the second card-pushing plate are controlled by the head magnetic control device until a certain number of cards are stacked. The stacking height and relative position are controlled by the height magnetic control device.

[0016] Third, start the second driving motor. The second driving motor drives the first driving wheel to rotate. The first driving wheel drives the second driving wheel. The first driving wheel and the second driving wheel drive the first driven wheel and the second driven wheel to rotate respectively. The second driving wheel transmits the power to the cam transmission member. The cam transmission member drives the large rocker arm. The large rocker arm drives the second card-pushing plate to swing back and forth first and then push flat, so as to push the stacked mahjong tiles to the card-supporting plate and complete the card-pushing work.

[0017] Fourth, the first driven wheel and the second driven wheel drive the first rocker arm and the second rocker arm to rotate respectively. One ends of the first rocker arm and the second rocker arm are respectively in contact with the arc-shaped protrusions of the transmission plate. Each time it rotates and touches the arc-shaped protrusions, the transmission plate drives the card-supporting plate to move upward, thus pushing the mahjong tiles up to the desktop of the mahjong table. When rotating away from the position of the arc-shaped protrusions, the card-supporting plate automatically drops under the action of gravity, so that the card-supporting plate returns to the original position. During the process of lifting and lowering, the two side telescopic rods are driven to lift and lower. When not working, the telescopic rods play a supporting role.

[0018] The advantages of the present invention are as follows:

[0019] The structure of this application is simple and has a low failure rate. It realizes the actions of lifting and lowering the card support and pushing the cards forward and backward with one motor, which not only saves the production cost but also reduces the failure rate of the machine. The traditional translational pushing action of the pushing plate is changed to a forward and backward swinging followed by a translational push, which improves the stability and saves effort. Compared with the current pushing mechanisms on the market, this structure saves 10% of the production cost of a set of plastic parts. Three large rocker arms are set to support the forward and backward movement of the pushing plate, dispersing the stress area and increasing the structural stability. The large rocker arm and the second pushing plate are fixed by three screws, eliminating the traditional manual adjustment and fixation steps and also saving some labor costs.

[0040] The implementation principle of this embodiment is as follows: First, the card-pushing mechanism is installed inside the mahjong table through the installation holes 32. There are mahjong tiles with different volumes on the market currently, and the lengths of stacks of mahjong tiles with different sizes are different. A fine-tuning needs to be performed according to the different specifications and sizes of the mahjong tiles.

The distance can be adjusted according to the actual stacking length of the mahjong tiles. The adjustment range is limited by the limit sliding groove 34. After adjusting to the appropriate position, a fixed bolt is passed through the limit sliding groove 34 and connected with the fixed bolt hole 38 to complete the fixation.

[0041] Second, start the first driving motor 20 to drive the transmission wheel 19. The transmission wheel 19 transmits the power to the first connecting rod 21 and the second connecting rod 18. The first connecting rod 21 drives the card-receiving plate 16 to move upward, lifting the mahjong tile to a position parallel to the card placement plate 2. The mahjong tile enters through the card inlet of the card-feeding plate 12 and is placed on the fixed opening of the card-receiving plate 16. When receiving the first card, the card-receiving plate 16 drops. When receiving the second card, the second connecting rod 18 drives the first card-pushing plate 14 to swing, pushing the mahjong tile onto the card placement plate 2. Two cards stacked together form a group, and this process is repeated in a cycle. The accuracy of the lifting of the card-receiving plate 16 and the pushing distance of the second card-pushing plate 3 are controlled by the head magnetic control part 39 until a certain number of cards are stacked. The stacking height and relative position are controlled by the height magnetic control part 31.

[0042] Third, start the second driving motor 5. The second driving motor 5 drives the first driving wheel 26 to rotate. The first driving wheel 26 drives the second driving wheel 25. The first driving wheel 26 and the second driving wheel 25 respectively drive the first driven wheel 27 and the second driven wheel 24 to rotate. The second driving wheel 25 transmits the power to the cam transmission part 17. The cam transmission part 17 drives the large rocker arm 7. The large rocker arm 7 drives the second card-pushing plate 3 to swing back and forth first and then push horizontally, thus pushing the stacked mahjong tiles onto the card supporting plate 1 to complete the card-pushing work.

[0043] IV. The first driven wheel 27 and the second driven wheel 24 drive the first rocker 28 and the second rocker 29 to rotate respectively. One end of the first rocker 28 and the second rocker 29 is in contact with the arc-shaped protrusion 15 of the transmission plate 30 respectively. Each time it rotates and touches the arc-shaped protrusion 15, the transmission plate 30 drives the card-supporting plate 1 to move upward, so as to push the mahjong tiles to the tabletop of the mahjong table. When it rotates away from the position of the arc-shaped protrusion 15, the card-supporting plate 1 automatically descends under the action of gravity, so that the card-supporting plate 1 returns to the original position. During the process of moving up and down, the two-side telescopic rods 23 are driven to move up and down. When not working, the telescopic rods 23 play a supporting role.

The transmission wheel (19) transmits the power to the first connecting rod (21) and the second connecting rod (18). The first connecting rod (21) drives the card-receiving plate (16) to move upwards to lift the mahjong cards to a position parallel to the card-placement plate (2). The mahjong cards enter through the card-inlet of the card-inlet plate (12) and are placed on the fixed opening of the card-receiving plate (16). When receiving the first card, the card-receiving plate (16) drops. When receiving the second card, the second connecting rod (18) drives the first card-pushing plate (14) to swing, and pushes the mahjong cards onto the card-placement plate (2). Two cards are stacked together as a group, and this process is repeated in a cycle. The accuracy control of the lifting of the card-receiving plate (16) and the pushing distance of the second card-pushing plate (3) is controlled by the head magnetic control part (39). Until a certain number of cards are stacked, the stacking height and the relative position are controlled by the height magnetic control part (31); Third, start the second driving motor (5). The second driving motor (5) drives the first driving wheel (26) to rotate. The first driving wheel (26) drives the second driving wheel (25). The first driving wheel (26) and the second driving wheel (25) respectively drive the first driven wheel (27) and the second driven wheel (24) to rotate. The second driving wheel (25) transmits the power to the cam transmission part (17). The cam transmission part (17) drives the large rocker arm (7). The large rocker arm (7) drives the second card-pushing plate (3) to swing back and forth first and then push horizontally, so as to push the stacked mahjong cards to the card-holding plate (1) to complete the card-pushing work; IV. The first driven wheel (27) and the second driven wheel (24) drive the first rocker (28) and the second rocker (29) to rotate respectively. One end of the first rocker (28) and the second rocker (29) contacts with the arc-shaped protrusion (15) of the transmission plate (30). Each time when rotating and touching the arc-shaped protrusion (15), the transmission plate (30) drives the card supporting plate (1) to move upward, thereby pushing the mahjong tiles to the desktop of the mahjong table. When rotating away from the position of the arc-shaped protrusion (15), the card supporting plate (1) automatically descends under the action of gravity, so that the card supporting plate (1) returns to the original position. During the process of moving up and down, the two side telescopic rods (23) are driven to move up and down. When not working, the telescopic rods (23) play a supporting role.
