Technical Field

The invention belongs to the technical field of mahjong machines, and particularly relates to a mahjong machine tile feeding system.

Background

In a traditional mahjong machine, the mahjong tiles are generally lifted vertically from a shuffling barrel to a mahjong machine panel, namely: the overlapped mahjong tiles are firstly all stacked on the tile storage plate, then are horizontally pushed to the tile lifting plate, and the tile lifting plate is vertically lifted to be flush with the tabletop, so that the mahjong tiles are vertically conveyed to the panel of the mahjong machine. For example, the chinese patent application with publication number CN111023388A discloses a mahjong machine and a horizontal pushing and tile feeding device and a tile bearing plate lifting driving mechanism thereof, wherein the horizontal pushing and tile feeding device comprises a tile bearing plate for bearing and arranging a plurality of piles of mahjong tiles, a tile lifting plate for sending the plurality of piles of mahjong tiles to a table surface at one time, and a tile pushing plate for pushing the plurality of piles of mahjong tiles on the tile bearing plate to the tile lifting plate, the tile lifting plate is positioned at the inner side of the tile bearing plate, and the tile pushing plate is positioned at the outer side of the tile bearing plate and pushes the tiles from outside to inside.

The mahjong machine has the following disadvantages: mahjong tiles are horizontally pushed from the tile storage plate to the tile lifting plate by the tile pushing plate, and because the periphery of the tile lifting plate is not provided with mahjong tile protection measures, the problems that the mahjong tiles fall off or a mahjong tile queue is twisted and the like easily occur during pushing, and the tile loading fault is caused; the mahjong machine panel and the mahjong lifting plate are respectively paved with the flocking tablecloth, so that the mahjong lifting plate returns to the table top, the flocking tablecloth on the mahjong lifting plate can not completely cover the mahjong lifting plate, gaps exist between the flocking tablecloth of the mahjong lifting plate and the mahjong machine panel, the mahjong machine panel is uneven, playing of mahjong is affected, and attractiveness of the table top is affected.

In order to solve the above problems, a mahjong machine of slope tile lifting or roller coaster tile lifting type appears in the prior art, namely: when the mahjong tiles are loaded, one end of the mahjong tile lifting plate descends (the other end of the mahjong tile lifting plate ascends or keeps the position unchanged and is mainly determined by the position of a hinged point between the mahjong tile lifting plate and the rack) to be connected with the tile outlet of the mahjong tile storage channel, the mahjong tiles in the mahjong tile storage channel are immediately pushed onto the mahjong tile lifting plate, and after the pushing is completed, the mahjong tiles carried by the mahjong tile lifting plate are turned to be flush with the mahjong machine panel, so that the mahjong tiles are conveyed to the mahjong machine panel in a slope mode.

The Chinese patent application with the publication number of CN109248436A discloses a roller coaster type eight-mouth full-automatic mahjong machine, which comprises a rack, wherein a large disc is arranged in the rack, each side of the large disc is provided with two outlets, and a first tile lifting and bearing plate and a second tile lifting and bearing plate are respectively arranged at the two outlets; each side of the large plate is provided with a first card sending channel and a second card sending channel, the first card lifting and holding plate is positioned at the end of the first card sending channel, and the second card lifting and holding plate is positioned at the end of the second card sending channel; the first card lifting and holding plate is provided with a card lifting position which is turned relative to the outlet and is connected with the end of the card delivery of the first card delivery channel, and a card holding position which is turned to be flush with the outlet; the second card lifting and holding plate is provided with a card lifting position which is turned relative to the outlet and is connected with the end of the card delivery of the second card delivery channel, and a card holding position which is turned to be flush with the outlet.

The existing slope tile-lifting mahjong machine has the following disadvantages: the mahjong tile lifting position is located on the side of the width direction of the mahjong tile lifting plate, the mahjong tile pushing mechanism pushes a row of mahjong tiles to the mahjong tile lifting plate one by one, and therefore a longer distance mahjong tile storage channel needs to be arranged, the mahjong tile feeding time is long, the mahjong tile feeding efficiency is low, and the size of the mahjong tile machine is increased in vain.

Disclosure of Invention

The invention aims to provide a mahjong machine tile feeding system which is fast in tile feeding and high in efficiency.

In order to achieve the purpose, the technical scheme of the invention is as follows:

a mahjong machine tile feeding system comprises a rack, wherein a tile stacking device and a tile pushing and lifting device are arranged on the rack, the tile stacking device is used for stacking tiles and pushing the stacked tile piers to a tile storage plate one by one, and the tile pushing and lifting device is used for sending the mahjong tiles on the tile storage plate to a panel of the mahjong machine; the tile pushing and lifting device comprises a tile lifting plate arranged in parallel with the tile storage plate, the tile lifting plate is arranged at a tile lifting port of the panel of the mahjong machine in a turnover mode, and the turnover central axis of the tile lifting plate extends along the length direction of the tile lifting plate;

the tile lifting plate is provided with a tile lifting position which is turned relative to the panel of the mahjong machine to receive mahjong tiles from the tile storage plate and a tile receiving position which is flush with the panel of the mahjong machine.

In the invention, the tile lifting plate can turn relative to the panel of the mahjong machine to realize slope tile discharging, but the turning center line of the tile lifting plate extends along the length direction of the tile lifting plate, so that mahjong tiles from the tile storage plate are received from the length direction side; because the mahjong tiles are lifted from the side slope of the length direction, the mahjong tiles on the tile storage plate can be horizontally pushed onto the tile lifting plate by one step, the tile feeding distance is greatly shortened, the tile feeding time is saved, and the tile feeding efficiency is improved.

Meanwhile, due to the fact that long-distance tile pushing is not needed, the size of the mahjong machine can be greatly reduced under the condition that other internal structures of the mahjong machine are not changed, the size of the shuffling barrel can be increased under the condition that the size of the mahjong machine is not changed, and the tile lifting plate with a larger area can be arranged under the condition that the sizes of the mahjong machine and the shuffling barrel are not changed, so that more mahjong tiles can be borne, and more playing methods can be provided for players.

Preferably, in the mahjong machine tile feeding system, the tile lifting plate has a first length direction side far away from the tile storage plate and a second length direction side close to the tile storage plate, and the first length direction side is hinged with the mahjong machine panel;

the mahjong tile storage device is characterized in that a tile feeding driving mechanism is arranged on the rack and used for driving the second length direction side to turn around the first length direction side, and the tile feeding driving mechanism is also used for pushing mahjong tiles on the tile storage plate to the tile lifting plate from the second length direction side.

The first length direction side of the tile lifting plate is hinged with the panel of the mahjong machine, so that the overturning central axis of the tile lifting plate is positioned on the first length direction side, the second length direction side has larger overturning amplitude, and the tile lifting plate structure is more compact; especially, the first length direction side of the tile lifting plate can not be tilted to be above the surface of the mahjong machine, and can not be extruded with the surface plate of the mahjong machine when falling back, so that the flocking table cloth on the tile lifting plate can be laid in the same area as the tile lifting plate, and no gap exists between the tile lifting plate and the surface plate of the mahjong machine, so that the surface of the mahjong machine is more smooth, the playing of tiles can not be influenced, and the attractiveness of the surface is greatly improved.

In the invention, the tile feeding driving mechanism can drive the tile lifting plate to descend or ascend, and can push the mahjong tiles on the tile storage plate to the tile lifting plate when the tile lifting plate descends, thereby greatly saving the power cost required for feeding the mahjong tiles, reducing the number of control nodes in the mahjong machine and reducing the failure occurrence rate of the mahjong machine.

The mahjong tile lifting plate is erected on the mahjong tile storage plate after the second length direction side of the mahjong tile lifting plate descends, the size of an included angle between the mahjong tile lifting plate and the mahjong tile storage plate has a large influence on whether mahjong tiles can be stably transferred from the mahjong tile storage plate to the mahjong tile lifting plate, generally, the size of the included angle between the mahjong tile lifting plate and the mahjong tile storage plate is closer to 180 degrees, and therefore the mahjong tiles can be more stably transferred.

Therefore, preferably, in the tile feeding system of the mahjong machine, the tile storage plate comprises a tile storage platform for storing mahjong tiles, the tile storage platform is arranged from one side far away from the tile lifting plate to one side close to the tile lifting plate in an inclined and upward manner, and one side of the tile storage platform far away from the tile lifting plate is provided with a tile storage guardrail for preventing the mahjong tiles from sliding off from the tile storage platform;

the mahjong tile storage plate is arranged on the mahjong tile pushing seat, the mahjong tile lifting plate at the mahjong tile lifting position is arranged on the mahjong tile storage platform, and the mahjong tile feeding driving mechanism is used for driving the mahjong tile storage plate to move towards the mahjong tile lifting plate along the mahjong tile pushing seat so as to push mahjong tiles to the mahjong tile lifting plate;

the mahjong stacking device comprises a mahjong stacking mechanism, the mahjong stacking mechanism comprises a mahjong stacking seat arranged at the mahjong feeding end of the mahjong storage plate, a mahjong stacking platform and a mahjong stacking guardrail are formed on the mahjong stacking seat, the mahjong stacking platform and the mahjong storage guardrail are located on the same plane, and a mahjong stacking space is defined by the mahjong stacking platform and the mahjong stacking guardrail; the mahjong stacking guardrail is provided with a mahjong stacking position which is positioned at the side of the mahjong stacking platform and assists in stacking mahjong and a shrinkage position which moves synchronously with the mahjong storage plate and compresses the mahjong stacking space to shrink into the periphery of the mahjong machine.

The mahjong storage platform is arranged to be inclined upwards from one side far away from the mahjong lifting plate to one side close to the mahjong lifting plate, so that when the mahjong lifting plate descends, the included angle between the mahjong lifting plate and the mahjong storage plate is closer to 180 degrees, and the translation obstruction of the mahjong lifting plate to mahjong tiles is reduced. Because the card storage platform is obliquely arranged, the card storage guardrail is arranged on one side of the card storage platform, which is far away from the card lifting plate, and is necessary.

In the invention, the mahjong tiles can be transferred from the tile storage plate to the tile lifting plate in the following mode: the mahjong tile loading driving mechanism drives the mahjong tile storage plate to move towards the mahjong tile lifting plate so as to push mahjong tiles onto the mahjong tile lifting plate; it can also be: the mahjong storage plate keeps unchanged in position, and the mahjong tiles on the mahjong storage plate are directly pushed by the mahjong tile feeding driving mechanism to move towards the direction of the mahjong tile lifting plate. The first mode is preferably adopted in the invention, because when the mahjong storage plate is always kept unchanged in position, the area of the mahjong machine is always kept unchanged; when the position of the mahjong storage plate can be changed, the area of the mahjong machine is reduced, and when the mahjong machine needs to be packed and transferred, the mahjong machine can be packed by adopting smaller packages, so that the transportation cost and the transportation space are saved; moreover, the card lifting plate can be arranged closer to the center of the shuffling barrel, so that players can grab cards conveniently.

In order to smoothly enter the mahjong tile storage plate from the mahjong tile stacking seat, the mahjong tile stacking seat and the mahjong tile storage plate are positioned on the same plane; in order to enable the periphery of the mahjong machine to be integrally retracted, the mahjong tile stacking space is arranged to be deformable, and the mahjong tile stacking guardrails can synchronously move along with the mahjong tile storage plate.

In the mahjong machine tile feeding system, the tile feeding driving mechanism comprises:

a mahjong loading motor;

a transmission cam linked with an output shaft of the mahjong loading motor;

the card pushing transmission component is arranged between the transmission cam and the card storage plate, and the card storage plate is driven by the card pushing transmission component to be close to or far away from the card lifting plate;

the tile lifting transmission component is arranged between the transmission cam and the tile lifting plate, and the tile lifting plate is driven by the tile lifting transmission component to turn relative to the panel of the mahjong machine.

The tile feeding driving mechanism is only provided with one tile feeding motor, and the driving cam linked with the tile feeding motor is adopted to respectively drive the tile pushing driving assembly and the tile lifting driving assembly so as to drive the tile lifting plate and the tile storage plate to implement corresponding actions, so that the structure of the mahjong machine is simplified, the power cost is greatly saved, the number of control nodes in the mahjong machine is reduced, and the failure rate of the mahjong machine is also greatly reduced.

Preferably, in the tile feeding system of the mahjong machine, the tile lifting transmission assembly comprises:

the mahjong lifting seat is fixedly arranged on the bottom surface of the mahjong lifting plate and is provided with a mahjong lifting curve groove;

the fixed end of the mahjong lifting rocker arm is hinged with the rack, the free end of the mahjong lifting rocker arm is provided with a mahjong lifting roller, and the mahjong lifting roller is matched with the mahjong lifting curved groove in a rolling manner to drive the mahjong lifting plate to turn over;

the mahjong tile loading device comprises a mahjong tile loading push rod, wherein one end of the mahjong tile loading push rod is fixedly connected with a mahjong tile lifting rocker arm, the other end of the mahjong tile loading push rod is provided with a mahjong tile loading roller, and the mahjong tile loading roller is matched with a mahjong tile loading curved surface groove formed in a transmission cam in a rolling mode to drive the mahjong tile lifting rocker arm to swing.

Because the mahjong loading roller is matched with the mahjong loading curved surface groove in a rolling way, when the mahjong loading motor drives the transmission cam to rotate, the groove wall of the mahjong loading curved surface groove can push and pull the mahjong loading push rod, and further the mahjong lifting rocker arm is driven to swing; the swing of the mahjong lifting rocker arm further drives the mahjong lifting roller to roll along the mahjong lifting curve groove, so that the mahjong lifting plate is driven to turn over.

Preferably, in the mahjong loading system of the mahjong machine, the mahjong lifting curved groove is provided with a positioning notch at a low position and a groove bottom at a high position, and a first limit corner is formed between the positioning notch and the mahjong lifting curved groove;

the tile lifting roller is provided with a jacking position which is positioned in the positioning groove and enables the tile lifting plate and the panel of the mahjong machine to be kept in a flush state, and a tile lifting position which rolls along the tile lifting curved groove and enables the tile lifting plate to turn around the turning central axis.

The positioning notch is at a low position, when the tile lifting roller is positioned at the positioning notch, the tile lifting plate can be kept flush with the panel of the mahjong machine, and under the limiting action of the first limiting corner, the tile lifting roller can be always positioned in the positioning notch when no external force is applied, so that the stable position of the tile lifting plate is ensured; only when the mahjong rising rocker arm swings, the mahjong rising roller can pass through the first limit corner and roll to the bottom of the mahjong rising curved groove along the mahjong rising curved groove, and therefore the mahjong rising plate can descend to receive mahjong tiles.

In the mahjong loading system of the mahjong machine, the mahjong loading curved groove comprises a descending section, a mahjong pushing section and an ascending section, the mahjong loading roller is provided with a descending position which rolls along the descending section to enable the mahjong lifting plate to descend, a mahjong pushing position which rolls along the mahjong pushing section to enable the mahjong storage plate to move towards the mahjong lifting plate to push mahjong to the mahjong lifting plate, and an ascending position which rolls along the ascending section to enable the mahjong lifting plate to ascend.

When the transmission cam rotates to enable the descending section to reach the mahjong tile feeding roller, the groove wall of the descending section pushes the mahjong tile feeding push rod to enable the mahjong tile lifting rocker arm to swing towards the side of the shuffling barrel in the process that the mahjong tile feeding roller rolls along the descending section, and the mahjong tile lifting roller rolls along the mahjong tile lifting curve groove to the groove bottom of the mahjong tile lifting roller to enable the mahjong tile lifting plate to descend to receive mahjong tiles; when the transmission cam rotates to enable the tile pushing section to reach the tile feeding roller, and the tile feeding roller rolls along the tile pushing section, the tile feeding push rod, the tile lifting rocker arm and the tile lifting plate are kept unchanged in position, and the transmission cam can drive the tile storage plate to move towards the tile lifting plate through the tile pushing transmission assembly to horizontally push mahjong tiles onto the tile lifting plate; when the transmission cam rotates to enable the rising section to reach the mahjong tile feeding roller, the groove wall of the rising section pulls the mahjong tile feeding push rod back to enable the mahjong tile lifting rocker arm to swing towards one side far away from the shuffling barrel in the process that the mahjong tile feeding roller rolls along the rising section, the mahjong tile lifting roller rolls towards the positioning groove opening along the mahjong tile lifting curve groove, and the mahjong tiles carried by the mahjong tile lifting plate are lifted to the tabletop.

In the mahjong loading system of the mahjong machine, the tile pushing transmission assembly comprises an S-shaped tile pushing track arranged on the bottom surface of the tile storage plate, the S-shaped tile pushing track comprises a pushing section and a returning section which are arranged in a central symmetry mode about a midpoint of the track, one end, far away from the midpoint of the track, of the pushing section is a pushing starting point, one end, far away from the midpoint of the track, of the returning section is a returning starting point, the pushing section and the returning section are both arc-shaped, and central angles of arcs are 90 degrees;

the radial position of the transmission cam is provided with a tile pushing roller which is matched with the S-shaped tile pushing track in a rolling way, the tile pushing roller is provided with a tile pushing preparation position which rolls from the middle point of the track to the starting point of the pushing process along the pushing process section, a tile pushing position which rolls from the starting point of the pushing process to the middle point of the track along the pushing process section so as to enable the tile storage plate to move towards the tile lifting plate, a return stroke preparation position which rolls from the middle point of the track to the starting point of the return stroke along the return stroke section, and a return stroke position which rolls from the starting point of the return stroke to the middle point of the track so as to enable the tile storage plate to return to the initial position;

the card-raising roller is provided with a first-stage card-raising position which rolls along the first-stage card-raising section to raise the card-raising plate, and a second-stage card-raising position which rolls along the second-stage card-raising section to continue raising the card-raising plate and return the card-storing plate to the initial position.

When the card feeding roller rolls along the descending section, the card pushing roller rolls along the pushing section from the middle point of the track, and the rolling track is just concentric with the rotating track of the transmission cam, so that the position of the card storage plate is kept unchanged; when the card loading roller rolls along the card pushing section, the card pushing roller continues to roll along the pushing section to the pushing starting point and reversely roll along the pushing section from the pushing starting point to the middle point of the track, and the card storing plate is pushed to move towards the card lifting plate in the rolling process; in order to adapt to the return preparation position and the return position of the mahjong pushing roller, the invention divides the seesaw section in the mahjong loading curved groove into a first-stage seesaw section and a second-stage seesaw section which are connected in sequence, when the transmission cam rotates to enable the first-stage seesaw section to reach the mahjong loading roller, the mahjong pushing roller also reaches the middle point of the track and rolls to the return starting point along the return section along with the rotation of the transmission cam, and the rolling track is just concentric with the rotation track of the transmission cam, so the mahjong storage plate also keeps the position unchanged; but the mahjong lifting plate rises to a certain height until one end of the mahjong facing to the mahjong storage plate is exposed above the panel of the mahjong machine, and the mahjong storage plate with the unchanged position can just protect the mahjong on the mahjong lifting plate from falling back; when the transmission cam rotates to enable the secondary raising section to reach the mahjong tile feeding roller, the mahjong tile pushing roller also reaches the return starting point and rolls to the middle point of the track along the return section along with the rotation of the transmission cam, and the mahjong tile storage plate is pushed to return to the initial position in the rolling process to wait for next mahjong tile pushing; and the mahjong lifting plate continues to rise until the mahjong lifting plate is flush with the panel of the mahjong machine.

Because the rising board is erected on the storage board after descending, and is influenced by the gradient and the thickness of the rising board and the possible height difference between the storage board and the rising board, the risk that the end surface of the mahjong tiles tightly props the second length direction side of the rising board easily occurs when the mahjong tiles are transferred from the storage board to the rising board, and once the risk occurs, a mistake of pushing and rising the mahjong tiles can occur.

In order to solve the problems, in the mahjong machine tile feeding system, the tile pushing seat is provided with the tile pushing assembly, the tile pushing assembly is used for upwards pushing the mahjong tiles on the tile storage plate towards one end of the tile lifting plate so as to prevent the mahjong tiles from being stuck at the lap joint of the tile storage plate and the tile lifting plate, and the tile storage platform is provided with a tile pushing port convenient for the tile pushing assembly to implement the tile pushing action.

After the mahjong tiles are jacked upwards towards one end of the tile lifting plate (namely the front end of the mahjong tiles defined by the advancing direction of the mahjong tiles) by adopting the tile jacking assembly, an avoiding space is formed between the front end of the mahjong tiles and the tile storage plate, and when the mahjong tiles are transferred from the tile storage plate to the tile lifting plate, the tile lifting plate shovels the mahjong tiles due to the fact that the mahjong tiles are brought into the avoiding space, so that the mahjong tiles and the tile lifting plate can be prevented from being jacked tightly.

Preferably, in the mahjong machine tile feeding system, the tile pushing assembly comprises:

the card pushing plate is movably arranged on the card pushing seat and is positioned below the card pushing port, and a card lifting avoiding groove is formed in the card pushing plate;

one end of the pushing push rod is fixedly connected with the mahjong lifting rocker arm, and the other end of the pushing push rod is provided with a mahjong pushing roller which is in rolling fit with the mahjong lifting avoiding groove;

the mahjong lifting seat is also provided with a mahjong lifting avoiding groove communicated with the groove bottom of the mahjong lifting curved groove, the mahjong lifting avoiding groove extends from the groove bottom of the mahjong lifting curved groove to one side far away from the mahjong lifting plate and is coincided with the swinging track of the mahjong lifting rocker arm, and the mahjong lifting roller rolls along the mahjong lifting avoiding groove along with the mahjong lifting roller and does not drive the mahjong lifting plate to lift;

the mahjong tile pushing section comprises a tile pushing section, a first-stage tile pushing section and a second-stage tile pushing section which are connected in sequence, the tile pushing roller is further provided with a tile pushing position which rolls along the tile pushing section to drive the tile lifting roller to roll along the tile pushing avoiding groove so as to enable the tile pushing push rod to lift the tile pushing plate, rolls along the first-stage tile pushing section to drive the tile storage plate to move towards the tile lifting plate so as to horizontally push the mahjong tile part to the first-stage tile pushing position on the tile lifting plate, and rolls along the second-stage tile pushing section to enable the tile pushing push rod to release the support of the tile pushing plate and enable the tile storage plate to completely horizontally push the mahjong tiles to the second-stage tile pushing position on the tile lifting plate.

Because the card pushing rod is linked with the card lifting swing arm, in order to ensure that the card pushing rod cannot drive the card lifting plate to lift when the card lifting roller rolls along the card lifting curved groove to drive the card lifting plate to turn over, the card lifting avoiding groove is arranged on the card lifting plate, and the card pushing rod is provided with the card pushing roller; when the card lifting roller rolls along the card lifting curve groove, the card pushing roller rolls along the card lifting avoiding groove, but the rolling cannot drive the card pushing plate to lift, and the card pushing roller has the capacity of pushing up the card pushing plate only when the card pushing roller rolls to the highest point of the card lifting avoiding groove.

When the transmission cam rotates to enable the mahjong tile loading roller to roll along the mahjong tile pushing section, the mahjong tile loading push rod drives the mahjong tile lifting rocker arm to continuously swing towards the direction of the shuffling barrel, the mahjong tile lifting roller enters the mahjong tile lifting avoiding groove from the mahjong tile lifting curved groove, and the swinging track of the mahjong tile lifting avoiding groove is overlapped with that of the mahjong tile lifting rocker arm, so that the state of the mahjong tile lifting plate cannot be changed due to the rolling of the mahjong tile lifting roller in the mahjong tile lifting avoiding groove, but the mahjong tile lifting roller can lift the mahjong tile lifting plate to upwards jack the mahjong tile towards one end of the mahjong tile lifting plate;

when the transmission cam rotates to enable the mahjong loading roller to roll along the first-stage mahjong pushing section, the mahjong pushing roller rolls along the pushing section from the pushing starting point to drive the mahjong storage plate to move towards the mahjong lifting plate along the supporting surface of the mahjong pushing seat, so that the front end of the mahjong is lapped on the mahjong lifting plate; in the process, the tile loading push rod, the tile lifting rocker arm and the tile pushing push rod are kept unchanged in position, the tile lifting plate keeps the descending state to receive the mahjong tiles, and the tile pushing plate keeps the tile pushing state;

when the transmission cam rotates to enable the card-loading roller to roll along the secondary card-pushing section, the card-loading push rod drives the card-lifting rocker arm to swing towards one side far away from the shuffling barrel, the card-lifting roller returns to the card-lifting curved groove from the card-pushing avoiding groove and is kept at the bottom of the card-lifting curved groove (the position is unchanged), and the card-pushing roller also relieves the jacking of the card-pushing plate and keeps at the card-pushing notch of the card-lifting avoiding groove (the position is unchanged); in the process, the tile pushing roller continuously rolls to the middle point of the track along the pushing process section, and the mahjong tiles are completely pushed to the tile lifting plate in a flat manner, so that one-time tile pushing is completed.

Compared with the prior art, the invention has the beneficial effects that:

(1) in the invention, the tile lifting plate can turn relative to the panel of the mahjong machine to realize slope tile discharging, but the turning central line of the tile lifting plate extends along the length direction of the tile lifting plate, so that mahjong tiles from the tile storage plate are received from the length direction side; because the mahjong tiles are lifted from the length direction, the mahjong tiles on the mahjong storage plate can be horizontally pushed onto the mahjong lifting plate in one step, the mahjong tile feeding distance is greatly shortened, the mahjong tile feeding time is saved, and the mahjong tile feeding efficiency is improved.

(2) The mahjong tile feeding system of the invention can greatly reduce the volume of the mahjong machine under the condition of not changing other internal structures of the mahjong machine, increase the volume of the shuffling barrel under the condition of not changing the volume of the mahjong machine, and arrange the mahjong tile lifting plate with larger area under the condition of not changing the volumes of the mahjong machine and the shuffling barrel, thereby being capable of bearing more mahjong tiles and providing more playing methods for players.

(3) According to the invention, the first length direction side of the tile lifting plate is hinged with the panel of the mahjong machine, so that the overturning central axis of the tile lifting plate is positioned on the first length direction side, the second length direction side has larger overturning amplitude, and the tile lifting plate structure is more compact; particularly, the first length direction side of the tile lifting plate cannot be tilted to be above the surface of the mahjong machine, and the tile lifting plate cannot be extruded with the panel of the mahjong machine when falling back, so that the flocked tablecloth on the tile lifting plate can be laid in the same area as the tile lifting plate, and no gap exists between the tile lifting plate and the panel of the mahjong machine, so that the surface of the mahjong machine is more smooth, the playing of tiles cannot be influenced, and the attractiveness of the desktop is greatly improved.

(4) In the invention, the tile feeding driving mechanism can drive the tile lifting plate to descend or ascend, and can push the mahjong tiles on the tile storage plate to the tile lifting plate when the tile lifting plate descends, thereby greatly saving the power cost required for feeding the mahjong tiles, reducing the number of control nodes in the mahjong machine and reducing the failure occurrence rate of the mahjong machine.

(5) According to the invention, the tile storage platform is arranged to be inclined upwards from one side far away from the tile lifting plate to one side close to the tile lifting plate, so that after the tile lifting plate descends, the included angle between the tile lifting plate and the tile storage plate is closer to 180 degrees, and the translation barrier of the tile lifting plate on the mahjong tiles is further favorably reduced.

(6) In the invention, the mahjong tiles can be transferred from the tile storage plate to the tile lifting plate in the following mode: the mahjong tile loading driving mechanism drives the mahjong tile storage plate to move towards the mahjong tile lifting plate so as to push mahjong tiles onto the mahjong tile lifting plate; it can also be: the mahjong storage plate keeps unchanged in position, and the mahjong tiles on the mahjong storage plate are directly pushed by the mahjong tile feeding driving mechanism to move towards the direction of the mahjong tile lifting plate; the first way is more preferable because, when the storage plate is always kept at the same position, the area of the mahjong machine is always kept unchanged; when the position of the mahjong storage plate can be changed, the area of the mahjong machine is reduced, and when the mahjong machine needs to be packed and transferred, the mahjong machine can be packed by adopting smaller packages, so that the transportation cost and the transportation space are saved; moreover, the card lifting plate can be arranged closer to the center of the shuffling barrel, so that a player can grab cards conveniently.

(7) In the mahjong tile pushing seat, the mahjong tile pushing seat is further provided with a mahjong tile pushing assembly used for pushing the mahjong tiles on the mahjong tile storage plate upwards towards one end of the mahjong tile lifting plate, after the mahjong tiles are pushed upwards towards one end of the mahjong tile lifting plate by the mahjong tile pushing assembly, an avoiding space is formed between the front ends of the mahjong tiles and the mahjong tile storage plate, when the mahjong tiles are transferred from the mahjong tile storage plate to the mahjong tile lifting plate, the mahjong tile lifting plate can shovel the mahjong tiles due to the fact that the mahjong tiles are brought into the avoiding space, and therefore the mahjong tiles and the mahjong tile lifting plate can be prevented from being tightly pushed.

Detailed Description

The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.

Example 1

As shown in fig. 1-15, the mahjong machine tile feeding system of the embodiment includes a frame, on which a tile stacking device a and a tile pushing and lifting device B are disposed, wherein the tile stacking device a is used for stacking tiles and pushing the stacked tiles one by one onto the tile storage plate 12, and the tile pushing and lifting device B is used for sending the mahjong tiles on the tile storage plate 12 onto the panel 100 of the mahjong machine.

As shown in fig. 1 and 2, the card stacking device a includes a card stacking mechanism 1, the card stacking mechanism 1 includes a card stacking base 11, a card sending channel 402 is formed in a card sending support 401 of the card sending mechanism 400, and mahjong tiles sucked up from a shuffling barrel are sent to the card stacking base 11 at a card outlet of the card sending channel 402 through the card sending channel 402 so as to be stacked into a tile pier.

The two opposite sides of the card stacking base 11 are respectively provided with a stacking and pushing mechanism 2 and a card storage plate 12, the stacking and pushing mechanism 2 comprises a card pushing head box 21 fixed on the frame, and the card pushing head box 21 is provided with a card pushing head 22 used for horizontally pushing the card piers on the card stacking base 11 to the card storage plate 12 one by one; the way of pushing the card by the card pushing head 22 is accomplished by using a conventional structure, and therefore, the detailed description thereof is omitted.

In the embodiment, as shown in fig. 3, the deck plate 200 is formed on the deck plate 11, for example, to receive two layers of piers, the height difference between the deck plate 200 facing the card sending channel 402 and the card sending channel 402 should be equal to the thickness of one mahjong tile, and the height difference may be slightly larger than the thickness of one mahjong tile but not allowed to be smaller than the thickness of one mahjong tile, otherwise the normal conveying of the second mahjong tile is affected.

When the card piers are two-layered, the card folding seat 11 can be fixedly arranged at the card outlet end of the card sending channel 402, or can be arranged at the card outlet end of the card sending channel 402 in a lifting manner, and in actual situations, the card folding seat is fixedly arranged at the card outlet end of the card sending channel 402; when the number of the card piers is three or more, the card stacking base 11 is preferably arranged at the card outlet end of the card sending channel 402 in a lifting way.

At the card outlet of the card feeding channel 402, the mahjong tiles fall in a downward-rushing mode, if the card bearing platform 200 is horizontally arranged, the front ends of the mahjong tiles can continue to rush forwards due to the inertia effect after contacting the card bearing platform 200, and the card falling is caused. To solve this problem, in the present embodiment, the card holding platform 200 is disposed to be inclined downward from a side close to the card feeding passage 402 to a side far from the card feeding passage 402, and the card stacking fence 300 is formed on a side of the card holding platform 200 far from the card feeding passage 402.

Because the inclined direction of the mahjong tile bearing platform 200 is consistent with the inclined direction of the mahjong tiles when the mahjong tiles fall, when the mahjong tiles fall on the mahjong tile bearing platform 200, the whole bottom surface of the mahjong tiles can be simultaneously contacted with the mahjong tile bearing platform 200, or the bottom surface of the mahjong tiles is contacted with the mahjong tile bearing platform 200 at a small included angle, and then the mahjong tiles slide along the mahjong tile bearing platform 200 for a certain distance and abut against the mahjong tile stacking guardrails 300; the second mahjong tiles are also stacked in the same manner, so that the cards can be prevented from being dropped on the premise that the card bearing platform 200 is kept static.

In this embodiment, the inclination angle of the card supporting platform 200, i.e. the included angle between the card supporting platform 200 and the horizontal plane, may be set between 5 ° and 60 °, preferably between 10 ° and 30 °; preferably, the angle of inclination is similar to the angle of inclination of the mahjong tile when falling. Because the card folding seat 11 is arranged obliquely, in order to facilitate the mahjong tiles to be transferred from the card folding seat 11 to the card storage plate 12, the card storage plate 12 is also in the same oblique state as the card folding seat 11.

That is, the card storage plate 12 of this embodiment includes the card storage platform 12a located on the same plane as the card holding platform 200, and the card storage guardrail 12b located on the same plane as the card stacking guardrail 300, and the card storage guardrail 12b is also fixed on one side of the card storage platform 12a to prevent the mahjong cards from sliding off the card storage platform 12a, and the side opposite to the card storage guardrail 12b is the card outlet of the card storage platform 12 a.

In this embodiment, the card storage plate 12 can move relatively to the card lifting plate 3, that is, the card storage plate 12 has a card storage position at the side of the card receiving platform 200 for receiving the mahjong cards and a card pushing position moving towards the card lifting plate 3 for pushing the mahjong cards out from the card outlet side. When the card storage plate 12 has displacement towards the card lifting plate 3, the card lifting plate 3 can be arranged closer to the center of the shuffling barrel, so that a player can grab cards more conveniently; meanwhile, great possibility is provided for the retraction of the periphery of the mahjong machine, and the mahjong machine is convenient to pack by adopting a smaller packing box.

As can be seen from fig. 4 and 8, the top surface of the card pushing base 6 of the present embodiment is a supporting surface of the card storage plate 12, the card storage plate 12 is driven by the card feeding driving mechanism 5 to move along the supporting surface, and the inclined angle of the supporting surface is consistent with the inclined angle of the card storage plate 12. As shown in fig. 2, 3 and 4, in the moving direction of the card storage plate 12, the support surface of the card pushing base 6 is narrower than the card storage plate 12, the card storage plate 12 at the starting point of pushing the card is mounted on the support surface at the side close to the card lifting plate 3, and the side far away from the card lifting plate 3 is suspended; and the card-feeding driving mechanism 5 is arranged on one side of the card-pushing seat 6 facing the card-lifting plate 3. Therefore, when the mahjong storage plate 12 moves along the supporting surface to the mahjong lifting plate 3, the space outside the mahjong pushing seat 6 is gradually vacated, so that the mahjong pushing seat is greatly retracted into the periphery of the mahjong machine, and the mahjong machine is conveniently packed by adopting a smaller packing box.

Since the mahjong tile stacking base 11 is in the same horizontal plane with the mahjong tile storage plate 12, in order to facilitate the overall retraction of the periphery of the mahjong machine, the mahjong tile stacking space on the mahjong tile stacking base 11 is also compressible. Specifically, the deck plate 200 and the stacking guardrails 300 in this embodiment are not all rigid planes, but have both rigid and flexible portions.

Specifically, as can be seen from fig. 1, 2 and 3, the card storage fence 12b has a backrest plate 11a extending to the card stacking base 11 side, the bottom end of the backrest plate 11a does not extend to the plane of the card supporting platform 200, but a first avoidance port 11b for avoiding the collision between the backrest plate 11a and the card sending support 11 due to the movement of the card storage plate 12 is reserved, and the height of the first avoidance port 11b is set to be about 1 cm; an auxiliary tile bearing plate 11c is fixedly arranged at the top of the tile pushing machine head box 21, the auxiliary tile bearing plate 11c is also narrower, so that a second avoidance port 11d for avoiding the collision between the back support plate 11a and the auxiliary tile bearing plate 11c due to the fact that the back support plate 11a moves along with the tile storage plate 12 is formed between the auxiliary tile bearing plate 11c and the back support plate 11 a; a flexible member 11e is fixedly connected between the back plate 11a and the auxiliary tile bearing plate 11c, when the back plate 11a moves along with the tile storage plate 12, the flexible member 11e can be bent freely, only when the mahjong tiles fall on the flexible member 11e, the flexible member 11e is extruded by the mahjong tiles and stretched, the mahjong tile bearing platform 200 and the auxiliary tile bearing plate 11c form the tile stacking guardrail 300 together, and at this time, the mahjong tile bearing platform 200 and the tile storage platform 12a are finally formed.

In this embodiment, the flexible member 11e may be made of cloth, and in order to form the flat card supporting platform 200, the flexible member 11e preferably completely covers the card supporting platform 200, so as to avoid the uneven height between the flexible member 11e and the auxiliary card supporting plate 11 c. Obviously, at the end of the card folding fence 300, the flexible member 11e can be set to be equal to the height of the card pier, so that the card pier can be transferred in order. In this case, it may be appropriate to bond the flexible member 11e to the auxiliary deck plate 11c or the back plate 11a via a back adhesive layer. Because the mahjong tile bearing platform 200 is arranged obliquely, a mahjong tile protecting part 11f which is arranged obliquely towards the mahjong tile receiving side of the mahjong tile bearing platform 200 can be selectively arranged at the top end of the back plate 11a so as to protect mahjong tiles; the card guard 11f is preferably integrally formed with the backrest plate 11a, and the card storage fence 12b may be provided with the same card guard 12 c.

In order to further avoid the collision between the back plate 11a and the auxiliary holding plate 11c or the card-sending support 11, the angle between the plane of the back plate 11a and the plane of the auxiliary holding plate 11c is set to be greater than 90 ° in this embodiment, so as to offset the inclination of the auxiliary holding plate 11 c. Obviously, the included angle is not too large, otherwise, the subsequent tile lifting is also affected; preferably, the included angle is set to about 100 degrees; accordingly, the card storage platform 12a and the card storage fence 12b of the card storage plate 12 have the same angle therebetween, so that the card pier can be smoothly transferred from the card stacking base 11 to the card storage plate 12.

Certainly, it is also feasible to arrange the mahjong tile stacking base 11 not to move synchronously with the mahjong tile storing plate 12, at this time, the first avoiding port 11b and the second avoiding port 11d do not need to be arranged, and the backrest plate 11a and the auxiliary mahjong tile bearing plate 11c are directly connected and fixed or integrally formed, so that the rigid and permanent mahjong tile bearing platform 200 and the mahjong tile stacking guardrail 300 are formed, and at this time, the periphery of the mahjong machine cannot be integrally retracted.

As shown in fig. 4 and seen in fig. 1, in the present embodiment, the tile pushing and lifting device B includes a tile lifting plate 3, the tile lifting plate 3 has a first longitudinal side 31 and a second longitudinal side 32, which are oppositely disposed, wherein the first longitudinal side 31 is hinged to the mahjong machine panel 100 through a hinge 4, and the second longitudinal side 32 is turned around the first longitudinal side 31 under the driving of the tile driving mechanism 5. That is, when the mahjong lifting plate 3 is raised, the mahjong lifting plate 3 is kept flush with the mahjong machine panel 100; when the card lifting plate 3 descends, the card lifting plate 3 is erected on the card storage plate 12.

The card lifting plate is arranged to be inclined at an angle of between 90 ° and 180 ° (excluding 90 ° and 180 °), more preferably between 120 ° and 180 ° (including 120 ° and 180 °), and most preferably between 150 ° and 180 ° (including 150 ° and 180 °), with respect to the card storage plate after being lowered.

As shown in fig. 4 and 5, the card-feeding driving mechanism 5 includes a card-feeding motor 51, a driving cam 52 is fixedly mounted on an output shaft of the card-feeding motor 51, and the card-lifting plate 3 and the driving cam 52 are driven by a card-lifting driving assembly 53.

The tile lifting transmission assembly 53 comprises a tile lifting seat 531 fixedly mounted on the bottom surface of the tile lifting plate 3, as shown in fig. 10, a tile lifting curved groove 531a is formed on the side surface of the tile lifting seat 531; the fixed end of the tile lifting rocker arm 532 is hinged with the frame, the free end is provided with a tile lifting roller 533 which is matched with the tile lifting curved groove 531a in a rolling way, and the tile lifting roller 533 can drive the tile lifting plate 3 to turn over after rolling along the tile lifting curved groove 531 a; the rolling power of the card-lifting roller 533 comes from the swing of the card-lifting rocker arm 532, and the swing of the card-lifting rocker arm 532 is driven by the card-loading push rod 534.

In this embodiment, the way that the mahjong loading push rod 534 drives the mahjong lifting rocker arm 532 to swing is as follows: the card-feeding pushing rod 534 has one end fixedly connected with the card-lifting rocker arm 532 and the other end provided with a card-feeding roller 535, the card-feeding roller 535 is in rolling fit with a card-feeding curved groove 521 (shown in fig. 6) arranged on the transmission cam 52, when the transmission cam 52 rotates, the card-feeding roller 535 rolls along the card-feeding curved groove 521 and pushes and pulls the card-feeding pushing rod 534, so that the card-feeding pushing rod 534 can drive the card-lifting rocker arm 532 to swing.

In order to ensure that the card lifting plate 3 is lifted stably, in this embodiment, two card lifting seats 531 and two card lifting rocker arms 532 are arranged at each card lifting plate 3, the two card lifting rocker arms 532 are linked through a linkage rod 536, and the card feeding push rod 534 is fixedly connected with the linkage rod 536.

In this embodiment, each of the tile lifting rocker arms 532 includes a swing support 532a, a through hole for conveniently passing through the linkage rod 536 is formed at the middle end of the swing support 532a, extension arms 532b are respectively inserted into two ends of the swing support 532a, one of the extension arms 532b is hinged to the rack through a hinged support 532c, and the other extension arm 532b is provided with a tile lifting roller 533. The structure of the mahjong lifting rocker arm 532 can adjust the length of the extension arm 532b without changing the connection structure between the mahjong lifting rocker arm 532 and the linkage rod 536 so as to adapt to mahjong machines with different specifications.

As shown in fig. 10, the card raising curved groove 531a of the card raising base 531 has a positioning notch 531aa at a lower position and a groove bottom 531ab at a higher position, and a first limit corner 531ac is formed between the positioning notch 531aa and the card raising curved groove 531 a. When the tile lifting roller 533 is located in the positioning notch 531aa (as shown in fig. 11), the tile lifting plate 3 is flush with the mahjong machine panel 100, and due to the limitation of the first limiting corner 531ac, the tile lifting roller 533 can be kept in the positioning notch 531aa when not stressed, so as to ensure the stable position of the tile lifting plate 3; when the card-lifting rocker arm 532 swings, the card-lifting roller 533 can cross the first limit corner 531ac and roll along the card-lifting curved groove 531a, and at this time, the card-lifting plate 3 descends and is erected on the card-storing plate 12 (as shown in fig. 12) to wait for card pushing.

In the present embodiment, the angle between the card lifting plate 3 and the card storage plate 12 after being lowered is between 90 ° and 180 ° (excluding 90 ° but including 180 °), preferably between 110 ° and 180 ° (including 110 ° and 180 °), and more preferably between 150 ° and 180 ° (including 150 ° and 180 °); within this range, the larger the angle between the two, the more smoothly the mahjong tiles are transferred from the tile storage plate 12 to the tile lifting plate 3.

As shown in fig. 8 and seen in combination with fig. 5, the storage plate 12 is movably mounted on the pushing base 6 and can slide along the supporting surface formed by the pushing base 6, and when the storage plate 12 moves towards the raising plate 3, the raising plate 3 will "scoop" the mahjong tiles. As shown in fig. 8 and 9, in order to ensure that the movement of the card storage plate 12 along the supporting surface does not deviate, the bottom surface of the card storage plate 12 is provided with a guide 12d penetrating through the card shoe 6, and the guide 12d adopted by the embodiment is two guide rods.

As shown in fig. 5 and 6, a row of concave areas 12e is formed on the bottom surface of the card storage plate 12 along the length direction of the card storage plate 12, each concave area 12e is in the shape of a strip, and the length extension direction of the concave area 12e is consistent with the moving direction of the card storage plate 12. After the depressed area 12e is arranged, the contact area between the card storage plate 12 and the card pushing seat 6 is greatly reduced, so that the moving resistance of the card storage plate 12 is reduced, and unnecessary abrasion between the card storage plate and the card pushing seat is also reduced.

The recessed area 12e may be only disposed on the bottom surface of the card storage platform 12a, or may extend from the bottom surface of the card storage platform 12a to the back surface of the card storage fence 12 b; therefore, the overall weight of the card storage plate 12 can be greatly reduced while the strength of the card storage guardrail 12b is ensured.

In this embodiment, the pushing action of the card storage plate 12 is also driven by the driving cam 52, and the card pushing driving assembly 54 is arranged between the driving cam 52 and the card storage plate 12, so that the card pushing and lifting can be synchronously driven by the card feeding driving mechanism 5.

Therefore, as shown in fig. 6, the curved card-playing groove 521 of the driving cam 52 includes a descending section 521a, a card-pushing section 521b and an ascending section 521c, which are connected in sequence, when the driving cam 52 rotates to make the descending section 521a reach the card-playing roller 535, the card-playing roller 535 rolls along the descending section 521a, so that the card-lifting rocker arm 532 swings towards the shuffling barrel, the card-lifting roller 533 rolls from the positioning groove opening 531aa to the groove bottom 531ab along the card-lifting curved groove 531a, so that the card-lifting plate 3 descends; when the driving cam 52 rotates to make the card pushing section 521b reach the card feeding roller 535, the card feeding roller 535 rolls along the card pushing section 521b, the card storage plate 12 moves towards the card lifting plate 3 under the driving of the card pushing driving component 54 to horizontally push the mahjong cards onto the card lifting plate 3; when the cam 52 rotates to make the rising section 521c reach the roller 535, the roller 535 rolls along the rising section 521c, the swing arm 532 swings back to the shuffling barrel, the roller 533 rolls from the groove bottom 531ab to the positioning notch 531aa along the curved groove 531a, and the rising board 3 rises to be flush with the panel 100 of the mahjong machine.

As shown in fig. 9 and seen in fig. 4, the card pushing transmission assembly 54 of the present embodiment includes an S-shaped card pushing track 541 disposed on the bottom surface of the card storage plate 12, the S-shaped card pushing track 541 includes a pushing section 541b and a returning section 541c disposed symmetrically with respect to the center of the track midpoint 541a, the pushing section 541b and the returning section 541c are both arc-shaped and have central angles of 90 °, wherein one end of the pushing section 541b away from the track midpoint 541a is a pushing starting point 541d, and one end of the returning section 541c away from the track midpoint 541a is a returning starting point 541 e; as shown in fig. 7 and 9, the radial position of the drive cam 52 is provided with a card-pushing roller 542 which is in rolling engagement with the S-shaped card-pushing rail 541, and the card-pushing roller 542 and the card-guiding groove 521 are respectively provided on two opposite sides of the drive cam 52.

In this embodiment, the tile pushing roller 542 has four movement processes of a tile pushing preparation position (from the middle point of the track to the pushing start point), a tile pushing position (from the pushing start point to the middle point of the track), a return preparation position (from the middle point of the track to the return start point), and a return position (from the return start point to the middle point of the track); in accordance therewith, as shown in FIG. 6, the raised section 521c in the superstate groove 521 is also divided into a primary raised section 521ca and a secondary raised section 521 cb.

When the card-loading roller 535 rolls along the descending segment 521a, the card-pushing roller 542 rolls along the pushing segment 541b from the middle point 541a of the track to the starting point 541d of the pushing process to prepare for pushing cards; in this process, the rolling track of the card pushing roller 542 is exactly concentric with the rotating track of the transmission cam 52, so that the card storage plate 12 keeps the position unchanged; when the card-loading roller 535 rolls along the card-pushing section 521b, the card-pushing roller 542 rolls from the starting point 541d to the middle point 541a of the track along the pushing section 541b, so that the card-storing plate 12 moves towards the card-lifting plate 3 to complete the card-pushing; when the tile feeding roller 535 rolls along the first-stage raising section 521ca, the tile lifting rocker arm 532 can only drive the tile lifting plate 3 to raise until the mahjong tiles are exposed on the mahjong machine panel 100 towards one side of the tile storage guardrail 300, and the tile pushing roller 542 rolls from the middle point 541a of the track to the return starting point 541e along the return section 541c to prepare for return; in the process, as the rolling track of the tile pushing roller 542 is exactly concentric with the rotating track of the transmission cam 52, the tile storage plate 12 also keeps the same position and is positioned at the tile pushing endpoint thereof so as to protect mahjong tiles on the tile lifting plate 3; when the card-feeding roller 535 rolls along the secondary raising section 521cb, the card-lifting plate 3 continues to raise until it is flush with the mahjong machine panel 100, and the card-pushing roller 542 rolls along the return section 541c from the return starting point 541e to the middle point 541a of the track to return the card-storing plate 12 to the initial position to wait for the card pier from the deck 11. Due to the slope and thickness of the card lifting plate 3 and the possible height difference between the card lifting plate 3 and the card storing plate 12, the top surface of the card lifting plate 3 and the top surface of the card storing plate 12 have more or less height difference, and the existence of the height difference can influence the smooth transfer of mahjong cards. In order to eliminate the influence, as shown in fig. 5 and 8, in the embodiment, the card pushing base 6 is provided with a card pushing assembly 55 for pushing up the mahjong tiles towards one end of the card lifting plate 3 so as to prevent the mahjong tiles from being stuck at the overlapping position of the card storage plate 12 and the card lifting plate 3, the card storage plate 12 is provided with a card pushing opening 12f for facilitating the card pushing assembly 55 to carry out a card pushing action, and the distance between the card pushing opening 12f and the card lifting plate 3 should be smaller than the length of one mahjong tile. The card ejecting opening 12f is strip-shaped, and the length extending direction of the card ejecting opening is consistent with that of the card storage plate 12, so that when mahjong tiles are stored on the card storage plate 12, all the mahjong tiles can be exposed at the card ejecting opening 12f and ejected.

As can be seen from fig. 8, the top surface of the card pushing base 6 of the present embodiment is a supporting surface of the card storage plate 12, and the inclined angle of the supporting surface is consistent with the inclined angle of the card storage plate 12. The top surface of the tile pushing seat 6 is formed with an accommodating groove 61, a tile pushing plate 551 is movably installed in the accommodating groove 61, the tile pushing rod 553 which is rotatably connected with the tile pushing plate 551 drives the tile pushing plate 551 to slide upwards along the accommodating groove 61, and the tile pushing plate 551 can extend out from the tile pushing port 12f to push up the mahjong tile towards one end of the tile lifting plate 3.

As shown in fig. 4 and 8, in the embodiment, the top end of the top plate 551 has a top plate 551b adapted to the top plate opening 12f, a limit step 551a is formed between the two ends of the top plate 551b and the top plate 551, and when the top plate 551 rises to the limit step 551a to be in contact with the bottom surface of the card storage plate 12, the top plate 551 cannot rise any more, so as to achieve the purpose of limiting the top plate height of the top plate 551.

As shown in fig. 4, 5 and 8, in order to facilitate the transmission between the card pushing rod 553 and the card pushing plate 551, the card pushing seat 6 of the present embodiment is further formed with a plurality of through holes 62 on the side surface thereof, which are communicated with the receiving groove 61; the card-pushing plate 551 has a connecting lug 551c extending from one of the through holes 62 to the outside of the card-pushing seat 6, and the card-pushing rod 553 is rotatably connected to the connecting lug 551 c.

As shown in fig. 5 and 8, in the present embodiment, the card-pushing rod 553 is rotatably connected to the engaging lug 551c in the following manner: a card-raising avoiding groove 552 is formed on the connecting lug 551c, the card-pushing rod 553 comprises a pushing rod joint 553a and a pushing arm 553b fixedly inserted with the pushing rod joint 553a, the pushing rod joint 553a is fixedly arranged at the end of the linkage rod 536, so that the linkage rod 536, the card-raising rocker arm 532 and the card-pushing rod 553 are linked; and the free end of the push arm 553b is provided with a card-ejecting roller 554 which is in rolling engagement with the card-raising escape groove 552.

The card-pushing plate 551 of the present embodiment is also provided with two engaging lugs 551c corresponding to the number of the card-pushing rods 553, so as to ensure that the card-pushing plate 551 can ascend and descend smoothly along the accommodating groove 61.

As shown in fig. 11, the card-raising and avoiding groove 552 in this embodiment has a groove bottom 522a at a lower position and a card-ejecting notch 522b at a higher position, the card-raising and avoiding groove 552 may be circumferentially closed, and an opening 522d for allowing the card-ejecting roller 554 to enter the card-raising and avoiding groove 552 may be disposed at the card-ejecting notch 522b, at this time, a second limit corner 522c should be ensured between the opening 522d and the card-ejecting notch 522b, so that the card-ejecting roller 554 can drive the card-ejecting plate 551 to move up and down along the receiving groove 61 at the card-ejecting notch 522b, and cannot be separated from the card-raising and avoiding groove 552 at the opening 522 d.

Since the ejector pin 553 is linked to the swing arm 532, the ejector pin 553 changes its position when the swing arm 532 swings. As shown in fig. 11, when the card-raising roller 533 is located at the positioning notch 531aa of the card-raising curved groove 531a, the card-top roller 554 is located at the groove bottom 531ab of the card-raising escape groove 552; as shown in fig. 12, when the card-raising roller 533 rolls from the positioning notch 531aa to the groove bottom 531ab along the card-raising curved groove 531a, the card-raising roller 554 also rolls from the groove bottom 522a of the card-raising avoiding groove 552 to the card-raising notch 522b, but the rolling does not cause the card-raising plate 551 to rise and fall, and when the card-raising roller 554 reaches the card-raising notch 522b, the card-raising roller 554 also reaches the card-raising notch 522b, so that the card-raising preparation is performed; as shown in fig. 10, 14 and 15, the card-raising seat 531 is further provided with a card-raising-avoiding groove 555 communicated with the groove bottom of the card-raising curved groove 531a, the card-raising-avoiding groove 555 extends from the groove bottom 531ab of the card-raising curved groove 531a to a side away from the card-raising plate 3 and coincides with the swing track of the card-raising rocker arm 532, when the card-raising rocker arm 532 continues to swing, the card-raising roller 533 enters the card-raising-avoiding groove 555 from the card-raising curved groove 531a, because the swing track of the card-raising-avoiding groove 555 coincides with the swing track of the card-raising rocker arm 532, the rolling of the card-raising roller 533 in the card-raising-avoiding groove 555 does not cause the state change of the card-raising plate 3, but the card-raising push rod 553 pulls the card-raising push rod 522b, so that the card-raising plate 551 along the accommodating groove 61 to perform the card-raising action, and at this time, the card-storing plate 12 starts to push the card.

In order to avoid the card pushing plate 551 affecting the card storage plate 12, the embodiment is configured to: after the front end of the mahjong tiles on the tile storage plate 12 is lapped on the tile lifting plate 3, the tile pushing plate 551 can descend to release the jacking of the mahjong tiles. However, before this point, the top plate 551 is still in the top attitude, and the storage plate 12 is still moving during the top process, so as to avoid the top plate 551 obstructing the movement of the storage plate 12 during this stage, as shown in fig. 8, the width of the top opening 12f is greater than the width of the top plate 551. When the card storage plate 12 moves to push cards, the card pushing plate 551 moves relatively from one side of the card pushing port 12f close to the card outlet of the card storage plate 12 to one side of the card pushing port 12f far away from the card outlet of the card storage plate 12; then, the mahjong tiles are descended to release the jacking of the mahjong tiles, and the tile storage plate 12 continues to push the tiles until the mahjong tiles are completely transferred to the tile lifting plate 3.

As shown in fig. 15, the top plate 551b has a top plate surface 551d, the top plate surface 551d is disposed obliquely downward from the top of the top plate 551b toward the storage plate 12, and the oblique direction of the top plate surface 551d is opposite to the advancing direction of the mahjong tiles on the storage plate 12; the slope of the top card surface 551d is larger than that of the card storage platform 12a, so that the situation that the card storage plate 12 is not blocked to push cards continuously when the top card plate 551 descends can be ensured, and the contact area between the mahjong cards and the top card surface 551d is larger and larger as the mahjong cards continue to move forwards, and the mahjong cards can be ensured to be kept stable in the card pushing process.

Correspondingly, as shown in fig. 6, in the curved groove 521 of the top card of the driving cam 52, the card pushing section 521b is configured to include a top card section 521ba, a first-stage card pushing section 521bb and a second-stage card pushing section 521bc, which are connected in sequence, when the driving cam 52 rotates to make the top card section 521ba reach the card pushing roller 535, the card pushing roller 535 rolls along the top card section 521ba to make the card lifting rocker arm 532 swing towards the shuffling barrel, the card lifting roller 533, i.e. the self-lifting curved groove 531a, rolls towards the inside of the card avoiding groove 555, so that the top card push rod 553 lifts the top card 551; when the transmission cam 52 rotates to enable the first-stage tile pushing section 521bb to reach the tile loading roller 535, the tile loading roller 535 rolls along the first-stage tile pushing section 521bb, the tile lifting rocker arm 532 keeps unchanged in position, the tile pushing roller 542 rolls along the pushing section 541b from the pushing starting point 541d, and the mahjong tile part is horizontally pushed onto the tile lifting plate 3; when the transmission cam 52 rotates to enable the secondary tile pushing section 521bc to reach the tile loading roller 535, the tile loading roller 535 rolls along the secondary tile pushing section 521bc, the tile lifting rocker arm 532 swings to one side far away from the shuffling barrel, the tile lifting roller 533 returns to the tile lifting curve groove 531a from the tile jacking avoiding groove 555, and the tile jacking push rod 553 releases jacking of the tile jacking plate 551; in the process, the tile pushing roller 542 continues to roll along the pushing section 541b to the middle point 541a of the track, and pushes the mahjong tile to the tile lifting plate 3.

Since the opening width of the card-pushing opening 12f of the card storage plate 12 is large, in order to ensure the strength of the card storage plate 12, as shown in fig. 8, the inner edge of the opening of the card-pushing opening 12f is provided with a plurality of reinforcing ribs 12g arranged along the length direction of the card-pushing opening 12f, and the card-pushing plate 551 is formed with notches 551e matched with the reinforcing ribs 12 g. The width of the ribs 12g should be less than the width of the tiles so that the ribs 12g do not interfere with the holding of the tiles by the tile-holding plate 551.

As shown in fig. 6, the card-loading surface groove 521 includes an outer curved surface 521d and an inner curved surface 521e which are disposed opposite to each other, and the wheel surface of the card-loading roller 535 is always in rolling contact with the outer curved surface 521d and the inner curved surface 521e in the process that the card-loading roller 535 rolls along the card-loading surface groove 521. Wherein, the outer curved surface 521d and the inner curved surface 521e are arranged vertically to the bottom surface of the slot at the starting point 521f of the curved slot 521 and in the first-level card pushing section 521 bb; in other positions, the outer curved surface 521d and the inner curved surface 521e are both inclined with respect to the central axis of the transmission cam 52, so that the card-handing push rod 534 can be pushed and pulled. Wherein the inclination directions of the outer curved surface 521d and the inner curved surface 521e are different in the descending section 521a and the top section 521ba and in the secondary card pushing section 521bc and the rising section 521c, which are consistent with the rolling direction of the card raising roller 533. Wherein, the inclination angles of the outer curved surface 521d and the inner curved surface 521e gradually increase from the starting point 521f of playing cards to the end point of the top card section 521 ba; the inclination angles of the outer curved surface 521d and the inner curved surface 521e gradually decrease from the starting point of the secondary tile pushing section 521bc to the starting point 521f of the upper tile; at the end of the card-pushing section 521ba and the beginning of the secondary card-pushing section 521bc, the inclination angles of the outer curved surface 521d and the inner curved surface 521e are exactly the same as the total swing angle of the card-lifting rocker arm 532.

The mahjong machine mahjong tile feeding system of the embodiment has the working principle that:

the mahjong tiles sucked from the shuffling barrel by the tile sucking wheel are sent to the tile stacking seat 11 one by one through the tile sending channel 402, the mahjong tiles fall onto the flexible piece 11e from the tile outlet end of the tile sending channel 402 in an inclined posture, under the extrusion of the mahjong tiles, the flexible piece 11e is provided with the tile bearing platform 200 and the tile stacking guardrail 300, the tile bearing platform 200 is also obliquely arranged from the tile receiving side to the tile stacking guardrail 300 side and is the same as the falling posture of the mahjong tiles, and therefore the tile falling phenomenon cannot occur; the overlapped card piers are horizontally pushed one by one onto the card storage plate 12 by the card pushing head 22, and the card loading can be started after the preset number of the card piers are stored on the card storage plate 12;

when a mahjong is played, the mahjong playing motor 51 is started, the transmission cam 52 rotates along with the transmission motor, and in the rotating process of the transmission cam 52, the mahjong playing curved surface grooves 521 and the mahjong pushing rollers 542 which are respectively positioned at two sides of the transmission cam 52 respectively perform corresponding actions under the driving of the transmission cam 52;
