Beneficial effects of the present invention:

The card pushing slot of the mahjong machine of the present invention comprises a base, an annular upright baffle plate and an annular card blocking side plate, wherein the annular upright baffle plate and the annular card blocking side plate are arranged on the base, the annular card blocking side plate is located at the periphery of the annular upright baffle plate, and the bending angle of the annular upright baffle plate is greater than 180°. Since the bending angle of the annular upright baffle plate is greater than 180°, the card pushing slot formed by the base, the annular upright baffle plate and the annular card blocking side plate has an arc-shaped card pushing track with a central angle greater than 180°. The card pushing slot designed in this way not only increases the card storage capacity, so that more mahjong tiles can be accommodated in the card pushing slot, but also the mahjong tiles in the card pushing slot are arranged in an arc shape, which saves more space compared with the traditional mahjong tiles arranged in a straight row.

The annular card pushing device of the mahjong machine of the present invention is usually connected between the stacking and pushing device and the card raising device of the mahjong machine. After adopting the above-mentioned card pushing groove, the horizontal space around the mahjong machine is fully utilized, so that the stacking and pushing device and the card raising device are close to each other but not staggered up and down, the component layout is more compact, and also provides favorable conditions for the lightweight design of the mahjong machine.

The automatic mahjong machine of the present invention is usually provided with four groups of card picking and transporting mechanisms, each group of card picking and transporting mechanisms includes a card feeding device, a stacking and pushing device, a card pushing device and a card raising device in sequence. After adopting the above-mentioned annular card pushing device, the problem of increasing the height of the mahjong machine due to the upper and lower overlap between two adjacent groups of card picking and transporting mechanisms is effectively avoided, and the card feeding device, the annular card pushing device and the card raising device in the same group of card picking and transporting mechanisms also hardly overlap each other, so that the thickness of the whole mahjong machine can be greatly reduced, which is conducive to the light and thin design of the mahjong machine. Due to the setting of the annular card pushing device, the two adjacent groups of card picking and transporting mechanisms do not overlap each other, and the restriction of the card pushing device on the position of the card raising port is reduced. The four card raising ports on the mahjong machine desktop can move closer to the center direction of the mahjong machine desktop. After the annular card pushing device pushes the mahjong cards from the card raising port, four rows of mahjong cards arranged in a windmill shape are formed on the mahjong machine desktop, which increases the desktop space between the mahjong cards and the players.

The card pushing slot is provided with a card inlet and a card outlet, and the bending angle of the annular upright baffle from the card inlet along the card pushing slot to the card outlet is greater than 180 degrees. With such a design, the card inlet and the card outlet of the card pushing slot are close to each other, which is conducive to the stacking and pushing device and the card lifting device to be close to each other without stacking, saving upper and lower space.

The annular baffle side plate is integrally formed with the base; or, the annular baffle side plate and the base are separately formed, and the annular baffle side plate and the base are connected by fasteners. The integral structure reduces assembly procedures and improves production efficiency; the split structure facilitates the annular baffle side plate and the base to be made of different materials, which can save costs.

The annular card pushing device includes a motor, a turntable and a card pushing block, wherein the motor is mounted on the base, the turntable is driven to rotate by the motor, and the turntable drives the card pushing block to push cards in the card pushing slot. The turntable driving method for pushing cards can ensure the stable output of the motor torque, improve the stability of the card pushing movement, and make the card pushing movement smoother.

The card pushing block is movably mounted on the annular upright baffle, and the card pushing block can slide circumferentially along the annular upright baffle. The annular upright baffle guides the card pushing movement of the card pushing block, and the card pushing movement of the card pushing block is more stable.

The turntable is provided with a strip rail extending from the inside to the outside, the strip rail is provided with a slider, the slider extends downward to form a plug-in column, the push-card block is provided with a plug-in hole, and the plug-in column is inserted into the plug-in hole. The sliding fit between the strip rail and the slider eliminates the influence of the change of the rotation radius, so that the push-card block can be driven by the turntable at any position of the annular push-card slot to apply a uniform and stable push force to the mahjong tiles.

These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

Embodiment 1

1, the push card slot of the mahjong machine proposed in the first embodiment of the present invention includes a base 50, an annular upright baffle 40 and an annular baffle side plate 70, the annular upright baffle 40 and the annular baffle side plate 70 are arranged on the base 50, the annular baffle side plate 70 is located at the periphery of the annular upright baffle 40, and the bending angle of the annular upright baffle 40 is greater than 180°. Since the bending angle of the annular upright baffle 40 is greater than 180°, the push card slot formed by the base 50, the annular upright baffle 40 and the annular baffle side plate 70 has an arc-shaped push card track with a central angle greater than 180°. The push card slot designed in this way not only increases the storage capacity of cards, so that more mahjong cards can be accommodated in the push card slot, and the mahjong cards in the push card slot are arranged in an arc shape, which saves more space compared with the traditional mahjong cards arranged in a straight line.

Specifically: the base 50 of the present embodiment is a disc-shaped structure, and an annular upright baffle 40 and an annular card baffle side plate 70 are provided on the upper part of the base 50, and the annular card baffle side plate 70 is located on the outer side of the annular upright baffle 40. The base 50, the annular card baffle side plate 70 and the annular upright baffle 40 surround the above-mentioned card pushing groove, the annular upright baffle 40 is the inner ring wall of the card pushing groove, and the annular card baffle side plate 70 is the outer ring wall of the card pushing groove. The part of the base 50 that surrounds the card pushing groove is used to carry mahjong tiles. The annular upright baffle 40 and the annular card baffle side plate 70 define the movement trajectory of the mahjong tiles in the card pushing groove. The distance between the annular upright baffle 40 and the annular card baffle side plate 70 is designed so that the mahjong tiles can move smoothly between the two, and the distance is usually slightly larger than the length of the mahjong tiles.

It can be understood that the card pushing groove can be designed to be an arc shape, an involute shape or a similar shape. It can be formed by the internal and external arrangement of the annular upright baffle plate 40 and the annular baffle side plate 70 as described in the present embodiment, or it can be formed by a plurality of short grooves connected by arcs. When the arc at the connection is large enough, the card pushing effect of the mahjong tiles moving smoothly therein can be achieved.

The annular baffle side plate 70 and the base 50 are formed separately, and the annular baffle side plate 70 and the base 50 can be made of different materials. The annular baffle side plate 70 and the base 50 are connected by fasteners, such as screws, buckles, etc., which can save costs. Those skilled in the art can easily think of: in other embodiments, the annular baffle side plate and the base are integrally formed, such as the annular baffle side plate and the base are integrally injection-molded plastic parts, or the annular baffle side plate and the base are connected as a whole by secondary injection molding.

The annular upright baffle plate 40 and the annular baffle side plate 70 defined in the present invention should be understood in a broad sense, including but not limited to the split molding structure described in this embodiment. The functions of the annular upright baffle plate 40 and the annular baffle side plate 70 are to respectively constitute the inner ring wall and the outer ring wall of the card pushing slot. Even if the card pushing slot is directly formed on the base 50 in an integrated molding manner, the two upright annular surfaces surrounding the card pushing slot also play the same role as the annular upright baffle plate 40 and the annular baffle side plate 70 of the present invention. Therefore, no matter how the card pushing slot is constructed, as long as it conforms to the definition of the card pushing slot in the present invention and can achieve the same or similar technical effects, it should be within the protection scope of the present invention, for example: the surface of the base is concave to form the card pushing slot; or an independently formed arc guide rail is installed on the base to form the card pushing slot on the arc guide rail, etc.

Furthermore, the card pushing slot of the present embodiment has a card inlet and a card outlet formed at both ends of the circumference, and mahjong tiles are pushed into the card pushing slot from the card inlet. When the number of mahjong tiles in the card pushing slot reaches a set number, the tiles are waiting to be loaded. When loading tiles, the mahjong tiles in the card pushing slot are pushed toward the card outlet in a counterclockwise direction, and the bending angle of the annular upright baffle from the card inlet along the card pushing slot to the card outlet is greater than 180°, which is very different from the existing card storage slot. In most existing mahjong machines, the card storage slot needs to be extended to the upper part of the adjacent card feeding mechanism to extend the length of the card storage slot, which is bound to The problem of adjacent mechanisms being staggered up and down occurs, resulting in an increase in the height of the entire mahjong machine. In the present embodiment, the bending angle of the annular upright baffle from the card inlet along the card pushing slot to the card outlet is greater than 180°. The length of the card pushing slot is extended by bending at a large angle, thereby increasing the card storage capacity of the card pushing slot, so that more mahjong tiles can be accommodated in the card pushing slot, and the card pushing slot will not extend above the adjacent card feeding mechanism. Therefore, the adjacent card picking and transporting mechanisms in the mahjong machine can be arranged without interference and without being staggered up and down, so as to reduce the height of the entire machine and meet the requirements of a lightweight design.

The card pushing groove of this embodiment can be designed to be an arc shape, an involute shape or a similar shape. It can be formed by the two annular baffles arranged inside and outside as described in this embodiment, or it can be formed by several short grooves connected by arcs. When the arc at the connection is large enough, the card pushing effect of the mahjong tiles moving smoothly inside can be achieved.

In conjunction with Fig. 2-5, the present invention also proposes an annular card-pushing device for an automatic mahjong machine, comprising a motor 10, a base 50, a turntable 20 and a card-pushing block 30, wherein the motor 10 is mounted on the base 50, the base 50 is provided with the above-mentioned card-pushing slot 52, the card-pushing slot 52 is provided with a card-entry port 51 and a card-discharging port 53, the turntable 20 is located above the base 50 and is driven to rotate by the motor 10, and the turntable 20 drives the card-pushing block 30 to perform a card-pushing motion in the card-pushing slot 52. The card-pushing slot 52 is provided with a card-entry port 51 and a card-discharging port 53, and the bending angle of the annular upright baffle 40 from the card-entry port 51 along the card-pushing slot 52 to the card-discharging port 53 is greater than 180°.

The annular card pushing device of this embodiment also includes a top cover 90, which is arranged above the turntable 20. The top cover 90 can be connected to the annular card blocking side plate 70, so as to completely cover the card pushing slot 52 to prevent foreign matter from falling into the card pushing slot 52 and hindering the movement of mahjong tiles.

In order to ensure the stability of the movement of the card pushing block 30, the card pushing block 30 is movably mounted on the inner ring wall of the card pushing slot 52 in this embodiment, that is, the card pushing block 30 is movably mounted on the annular upright baffle 40, and the card pushing block 30 can slide circumferentially along the inner ring wall of the card pushing slot 52. Specifically, a card slot 31 is provided on the inner side of the card pushing block 30, and the card pushing block 30 is mounted on the annular upright baffle 40 through the card slot 31. There is a clearance fit between the card slot 31 and the annular upright baffle 40. Under the premise of ensuring that the card pushing block 30 will not be separated from the annular upright baffle 40, the card pushing block 30 can slide freely along the annular upright baffle 40. A card pushing arm 32 for pushing cards is also provided on the outer side of the card pushing block 30. In some other embodiments, a buckle can be provided on the card pushing block, a slot can be provided on the annular upright baffle, and the buckle and the slot can be movably engaged, which can also achieve the above purpose. Other engaging methods will not be described in detail.

The motor 10 of the present embodiment is mounted at the lower part of the base 50, and the motor 10 is fixedly connected to the base 50 by screw connection, snap connection, etc., and the output shaft of the motor 10 is connected to the turntable 20 after being driven by one or more gears 101 to drive the turntable 20 to rotate. Since the card pushing slot 52 is not designed to be circular, the distance between the mahjong tiles and the rotation center of the turntable 20 will change during the card pushing process, so a dynamic connection structure needs to be designed between the turntable 20 and the card pushing block 30, so that the turntable 20 is not affected by the change of the rotation radius while pushing the card pushing block 30 to move. The turntable 20 of the present embodiment is provided with a strip guide 81 extending from the inside to the outside, and a slider 82 is provided on the strip guide 81. The strip guide 81 and the slider 82 form a driving part 80, and the slider 82 extends a plug-in column downward, and the card pushing block 30 is provided with a socket 33, and the plug-in column is inserted into the socket 33. When the turntable 20 rotates and drives the card pushing block 30 to slide along the annular upright baffle 40, the sliding fit between the strip guide rail 81 and the slider 82 eliminates the influence of the change in the rotation radius, so that the card pushing block 30 can be driven by the turntable 20 at any position of the card pushing slot 52 to apply a uniform and stable card pushing force to the mahjong tiles. It can be understood that the transmission between the motor and the turntable is not limited to gear transmission, but can also be a pulley transmission, a sprocket transmission or a friction wheel transmission.

In this embodiment, a sensor 100 for counting mahjong tiles is further provided at the card inlet 51 of the card pushing slot 52. The sensor 100 is generally a photoelectric sensor. When a pile of mahjong tiles enters the card pushing slot 52 from the card inlet 51, the photoelectric sensor is triggered, and the control system of the mahjong machine counts according to the trigger signal of the photoelectric sensor. Each time the photoelectric sensor is triggered, the control system counts once until the count reaches a set value. The control system controls the motor 10 to operate and the turntable 20 rotates to push the tiles.

In conjunction with Figure 6, the automatic mahjong machine proposed in this embodiment includes a shuffling barrel 500 and an annular card pushing device 300 arranged on the four sides of the shuffling barrel 500, the annular card pushing device 300 includes a motor 10, a base 50, a turntable 20 and a card pushing block 30, the motor 10 is installed on the base 50, the base 50 is provided with a card pushing slot 52, the card pushing slot 52 is provided with a card inlet 51 and a card outlet 53, the turntable 20 is located above the base 50 and is driven to rotate by the motor 10, and the turntable 20 drives the card pushing block 30 to push the cards in the card pushing slot 52. Specifically, a group of card picking and transporting mechanisms are arranged on each of the four sides of the shuffling barrel 500 of the automatic mahjong machine, and each group of card picking and transporting mechanisms includes a card feeding device 600, a stacking and pushing device 200, a ring-shaped card pushing device 300 and a card lifting device 400. Since the card feeding device, the card pushing device and the card lifting device in the prior art are all straight-line card feeding devices, in order to extend the length of the card pushing device to increase the card storage capacity, the card pushing device and the card lifting device in the two adjacent groups of card picking and transporting mechanisms can only be formed into a stacked form to meet the above requirements. Even so, the card storage capacity on the card pushing device is still limited, and this stacking form increases the thickness of the whole machine. The automatic mahjong machine of this embodiment adopts a ring-shaped card pushing device 300, which makes full use of the lateral space around the mahjong machine, effectively avoids the problem of overlapping between the two adjacent groups of card picking and transporting mechanisms and increasing the height of the mahjong machine, and the card sucking and feeding device 600, the ring-shaped card pushing device 300 and the card lifting device 400 in the same group of card picking and transporting mechanisms also hardly overlap, so that the thickness of the whole mahjong machine can be effectively reduced, which is conducive to the light and thin design of the mahjong machine.

Among them, the angle α formed by the card input direction of the card input port 51 and the card output direction of the card output port 53 is 60°～80°, preferably 75°～80°, such as 75°, 76°, 77°, 78°, 79°, 80°. It can be understood that in order to ensure that the mahjong tiles sent out from the card output port 53 can enter the card raising plate 410 of the card raising device 400 smoothly, the length direction of the card raising plate 410 is basically on the same straight line as the card output direction of the card output port 53, so the angle α is also related to the setting position of the card raising plate 410. If the angle α is too small, it is necessary to shorten the distance between the end of the card-raising plate 410 away from the card outlet 53 and the edge of the mahjong tabletop, which may cause the card-raising plate 410 and the card-feeding device 600 in the same group of card-picking and transporting mechanisms to overlap up and down; if the angle α is too large, when it is determined that the position of the card-raising plate 410 remains unchanged, it is necessary to move the annular card-pushing device 300 outward or reduce the radius of the annular card-pushing slot in the annular card-pushing device 300, which will increase the volume of the mahjong tabletop or reduce the card storage capacity of the annular card-pushing slot. The range of the angle α determined in this embodiment ensures that there is no overlap between the card-raising plate 410 and the card-feeding device 600 in the same group of card-picking and transporting mechanisms, and can meet the card storage capacity of the annular card-pushing slot.

The working principle of the automatic mahjong machine in this embodiment:

The mahjong tiles are distributed to the bottom of the card feeding device 600 in the four groups of card picking and transporting mechanisms by the rotation of the shuffling plate of the mahjong machine. The card feeding device 600 absorbs the mahjong tiles and feeds them into the stacking and pushing device 200. The stacking and pushing device 200 stacks the mahjong tiles into a pile and feeds them into the annular card pushing device 300 of this embodiment. The first pile of mahjong tiles enters the pushing slot 52 from the card inlet 51 and triggers the sensor 100. The mahjong machine control system starts counting. The second pile of mahjong tiles enters the pushing slot 52 from the card inlet 51 and pushes the first pile of mahjong tiles forward and triggers the sensor 100 again, and so on, until the control system counts to a set value. The card delivery is stopped and the control system is waiting for a card loading signal; when the annular card pushing device 300 receives the card loading signal, the card lifting plate 410 in the card lifting device 400 descends, and the card lifting plate 410 is connected with the card outlet 53 of the card pushing slot when it is in place, and the motor 10 drives the turntable 20 to rotate, and the turntable 20 drives the card pushing block 30 to move, and the card pushing block 30 is against the last pile of mahjong tiles, so that all the mahjong tiles in the card pushing slot 52 move toward the card outlet 53, and the mahjong tiles are sent to the card lifting device 400 pile by pile, and are pushed from the card lifting outlet to the mahjong machine table by the card lifting device 400, forming four rows of mahjong tiles arranged in a windmill shape on the mahjong machine table.
