The mounting structure of the card-feeding chamber door can be referred to a cover plate device for a card-feeding frame of a poker machine disclosed in patent document with publication number CN 103157272B. However, in practical use, the above structure has a problem that the cover plate is pushed up too high to be raised on a table top, or the cover plate cannot fall down by its own weight to be opened. In order to overcome these technical problems, the following two structures of the card inlet bin gate device are preferably adopted:

the first card inlet bin gate device is as shown in fig. 4 to 8, and comprises a card inlet bin gate 201, a sliding cover plate 202 and a cover plate bracket 203 which are arranged on a card inlet frame 205, wherein the cover plate bracket 203 is arranged on one side of the card inlet frame 205, the card inlet frame 205 is provided with a horizontal rail 2051 and a vertical rail 2052 which are communicated with each other, the sliding cover plate 202 is connected with the cover plate bracket 203 in a sliding way and driven to move by a cover plate motor 210 arranged on the cover plate bracket 203, the card inlet bin gate 201 is arranged above the sliding cover plate 202 and is drawn together by an elastic component to be overlapped up and down, as shown in fig. 9 and 10, the sliding cover plate 202 is provided with a plurality of pushing slopes 2022, the card inlet bin gate 201 is provided with a bearing slope 2012 which is matched with the pushing slope 2022, the sliding cover plate 202 drives the card inlet bin gate 201 to move along the horizontal rail 2051 so as to open or close the card inlet bin of the card inlet frame 205, the card inlet bin gate 201 is lifted along the vertical rail, the card feeding bin door 201 is drawn together through an elastic component to descend along the vertical track 2052.

The elastic component may be a spring, a leaf spring, or the like, and in this embodiment, as shown in fig. 7, 9, and 10, the elastic component is an elastic steel wire 216, the elastic steel wire 216 passes through a steel wire hole 2013 on the card-entering door 201, two ends of the elastic steel wire 216 are inserted into a steel wire groove 2021 on the sliding cover 202, and the steel wire groove 2021 preferably has a certain length such that the end of the elastic steel wire 216 moves in the steel wire groove 2021. Of course, the wire hole 2013 may be provided on the sliding cover 202, and the wire groove 2021 may be provided on the card hopper door 201. As shown in fig. 9 and 10, in the present embodiment, a plurality of guide blocks 2011 are disposed on two sides of the card inlet bin gate 201, and the guide blocks 2011 extend into the horizontal rail 2051 and/or the vertical rail 2052 of the card inlet frame 205 to achieve guiding movement. A rack 204 is fixed on the sliding cover 202, a gear 209 is rotatably arranged on the cover bracket 203, and a cover motor 210 drives the sliding cover 202 to move through the gear 209 and the rack 204. In addition, a horizontal rail groove communicated with the horizontal rail 2051 of the card inlet frame 205 is also arranged on the cover plate bracket 203 for moving and guiding the card inlet bin door 201, and a sensor 217 for detecting the moving position of the card inlet bin door 201 and/or the sliding cover plate 202 is also arranged on the cover plate bracket 203.

As shown in fig. 4, when the card feeding bin door 201 is opened, the card feeding bin door 201 is drawn by the elastic component to descend to be close to the sliding cover plate 202, and the card feeding bin door 201 and the sliding cover plate 202 are staggered by a certain horizontal distance under the matching of the pushing slope 2022 and the bearing slope 2012; when the card inlet bin door is closed, the sliding cover plate 202 always moves forwards and horizontally, the card inlet bin door 201 firstly moves along the horizontal rail 2051, and after the card inlet bin door moves horizontally to the bottom, the card inlet bin door pushes the card inlet bin door

The moving slope 2022 and the bearing slope 2012 are matched to push the card inlet bin door 201 to ascend along the vertical rail 2052 until the sliding cover plate 202 moves to a position, as shown in fig. 5, so that the card inlet bin door 201 is pushed from the lower side to the upper side to just cover the card placing opening of the card inlet frame 205 and be basically flush with the table top plate 11, and the card inlet bin door is closed. When the card feeding frame 205 is opened, the cover plate motor 210 drives the sliding cover plate 202 to retreat, the sliding cover plate 202 descends along the vertical rail 2052 under the drawing action of the elastic component, and then retreats along the horizontal rail 2051 and the sliding cover plate 202 together, and as the card feeding bin door 201 falls, the card feeding bin door 201 is lower than the height of a table top, so that the card feeding bin door 201 can be contracted below the table top when retreating and opening without extending out of one side of the table top; and after the sensor detects that the card bin door is opened, stopping the motor to work, and ending the opening of the card bin door. Because the card feeding bin door 201 and the sliding cover plate 202 are connected in a drawing mode through the elastic component, the defect that the card feeding bin door and the card feeding frame are locked and cannot descend due to self weight in the prior art is overcome.

The card delivering mechanism and the card discharging mechanism share one card distributing motor.

In this embodiment, the card-playing pressing plate 704 is hinged to the card-distributing bin 701 through a rotating shaft and gives a downward pressing tendency through a torsion spring (so that the card-playing pressing roller 705 presses the card-playing roller 706); the mahjong feeding roller B709 is provided with two annular bulges, and the mahjong feeding pressing plate B710 is provided with two grooves A corresponding to the annular bulges; the bottom wall of the card distributing bin 701 extends from the card storing space to the card inlet roller B709, a space for discharging paper scraps of the playing cards is reserved between the card inlet roller B709 and the card outlet roller wheel 706, and the moving part fault or the sensor fault caused by the paper scraps is avoided.

In the prior art, for example, in the card dealing mechanism disclosed in patent documents with publication numbers CN2801230Y and CN203303617U, a card dealing limiting plate is adopted to limit the card dealing height of the card outlet of the card dealing chamber, or the card dealing height of the card outlet of the card dealing chamber is limited by setting the distance between upper and lower rollers which roll up and down, and the number of playing cards passing through the card outlet of the card dealing chamber is limited by such a structure.

In order to solve the technical problem, the clearance between the press plate convex strip and the card feeding press plate A703 limits that only a few playing cards (at most three playing cards in the embodiment) enter, and the card feeding press plate A703 is designed by front-back dislocation and up-down overlapping of the press plate convex strip and the card feeding press plate A703 (the press plate convex strip is staggered with the axis of the card feeding roller A711 by a horizontal distance d, the press plate convex strip is closer to the card storage space of the card distributing bin 701 than the axis of the card feeding roller A711, and the press plate convex strip is lower than the top of the card feeding roller A711), so when a plurality of playing cards enter the clearance between the press plate convex strip and the card feeding roller A711, the entering end of the playing cards can be tilted to shift the upper and lower playing cards, thereby avoiding that the upper and lower playing cards can not be separated due to the fact that the press plate convex strip is static and has a smaller press contact area with the upper playing cards, and the static friction force between the press plate convex strip and the upper cards is far larger than the friction, and the power for conveying the playing cards comes from the card inlet roller A711 and is applied to the lower playing cards, so that the lower playing cards are conveyed to continue moving forwards, the upper playing cards are temporarily detained, and the upper playing cards and the lower playing cards are separated. Although the raised strip of the card pressing plate and the card inlet roller A711 separate two superposed playing cards, the situation that the two playing cards enter between the card inlet pressing plate B710 and the card inlet roller B709 in sequence still can be avoided, the technical scheme leads the upper playing card and the lower playing card to generate deformation through the matching of the concave-convex staggered structures on the card inlet pressing plate B710 and the card inlet roller B709, thereby avoiding the situation that the upper playing card and the lower playing card cannot be separated due to electrostatic adhesion, and because the card inlet pressing plate B is static and the concave-convex structure of the card inlet pressing plate B is smaller in pressure contact area with the upper playing card, the static friction force between the card inlet pressing plate B and the upper playing card is far larger than the friction force between the upper playing card and the lower playing card, and the conveying power of the playing card comes from the card inlet roller B and is applied to the lower playing card, therefore, the lower playing card is conveyed to move forwards continuously, and the upper playing card is temporarily detained, only the next playing card is fed out from between the card feed platen B710 and the card feed roller B709; the delivered playing cards are held by a card delivery roller 705 and a card delivery roller 706 and delivered to the card flipping device.

In other embodiments of the card distribution mechanism of the present invention, the upper and lower positions of the card feeding pressing plate a703 and the card feeding roller a711 may be interchanged, the upper and lower positions of the card feeding pressing plate B710 and the card feeding roller B709 may be interchanged, the upper and lower positions of the card discharging pressing plate 704 and the card discharging pressing roller 705 may be interchanged, and the concave-convex structures of the card feeding roller B709 and the card feeding pressing plate B710 may be interchanged or deformed to achieve effective separation of the plurality of playing cards. The mahjong tile feeding pressing plate A703, the mahjong tile feeding roller A711, the mahjong tile feeding pressing plate B710, the mahjong tile feeding roller B709, the mahjong tile discharging pressing plate 704, the mahjong tile discharging pressing roller 705 and the mahjong tile discharging roller wheel 706 are all parts, each part can be an integrally formed part or a combined part formed by a plurality of parts to achieve the same function, for example, the mahjong tile feeding pressing plate B710 can be an integrally formed part with a concave-convex structure, the mahjong tile feeding pressing plate B710 can also be formed by fixing a roller type part with a concave-convex ring on a pressing plate part, and in another embodiment, the roller type part with the concave-convex ring is installed on the pressing plate part in a mode of extremely large rotation resistance (namely, the roller type part can rotate relative to the pressing plate part, but has large rotation difficulty resistance).

Preferably, the card feeding pressing plate a703 is formed with a slope or a cambered surface on one side of the pressing plate convex strip close to the card feeding direction, so that only a few playing cards enter between the pressing plate convex strip and the card feeding roller a711 after a plurality of playing cards are separated by blocking, and the playing card separating pressure of the card discharging mechanism is reduced. Similarly, the card inlet pressing plate B710 is provided with an inclined plane or an arc surface at one side close to the card inlet direction, so that when two or three playing cards pass through the pressing plate raised line and the card inlet roller A711 and then are raised upwards, the two playing cards can be further conveniently moved up and down, only one or two playing cards are prevented from entering between the card inlet pressing plate B710 and the card inlet roller B709, the playing card separation pressure of the card outlet mechanism can be reduced, and the playing cards are prevented from being stuck. In addition, a space for tilting one end of the playing cards is arranged between the card feeding pressing plate A703 and the card feeding pressing plate B710, namely an upward inclined plane or an arc surface is formed behind the convex strip of the pressing plate, so that a plurality of playing cards passing through the convex strip of the pressing plate and the card feeding roller A711 can be fully tilted and thoroughly separated.

Preferably, the cross section of the press plate convex strip is V-shaped, so that the card pressing and separating effect is better.

The card dealing mechanism comprises a card dealing support arranged outside a card outlet of a card turning box 309, one end of the card dealing support is fixed on a card turning seat 301, a card dealing pressing plate 307 is arranged on the card dealing support, one end of the card dealing pressing plate 307 is hinged with the card dealing support, a card pressing piece 305 is arranged at the other end of the card dealing pressing plate 307, a channel for playing cards to pass through is formed between the card dealing support and the card dealing pressing plate 307, a card dealing roller 304 which corresponds to the card pressing piece 305 up and down is arranged on the card turning seat 301 or the card dealing support and is in transmission connection with a card dealing motor 302, and the card dealing pressing plate 307 endows the card pressing piece 305 with the trend of being close to the card dealing roller 304 through an elastic mechanism. In this embodiment, the elastic mechanism is a torsion spring sleeved on the hinge shaft of the card dealing pressing plate 307, one end of the torsion spring abuts against the card dealing bracket or the card turning seat, and the other end of the torsion spring abuts against the card dealing pressing plate 307.

Although two playing cards overlapped up and down are separated in the card distributing device, under the condition of extremely low probability, the possibility that two playing cards enter the card turning box still exists, therefore, preferably, in the embodiment, the card dealing roller 304 and the card pressing piece 305 are arranged up and down correspondingly, a gap for the playing cards to pass through is reserved between the card dealing roller 304 and the card pressing piece 305, a plurality of annular grooves are arranged on the card dealing roller 304, bulges corresponding to the annular grooves are arranged on the card pressing piece 305, and the bulges on the card pressing piece 305 protrude into the annular grooves on the card dealing roller 304. The card pressing member 305 is fixed on the card dealing pressing plate 307, or is integrally formed with the card dealing pressing plate 307, or is mounted on the card dealing pressing plate in a manner of great rotational resistance, so that the card pressing member 305 cannot rotate synchronously with the card dealing roller 304. Thus, the card delivery roller 304 and the concave-convex structure on the card pressing piece 305 are matched to enable the upper and lower playing cards to deform, so that the problem that the upper and lower playing cards cannot be separated due to electrostatic adhesion is avoided, the card pressing piece 305 cannot synchronously rotate with the card delivery roller 304, the pressing contact area between the concave-convex structure and the playing cards is small, the static friction force between the card pressing piece and the playing cards is far larger than the friction force between the upper and lower playing cards, the conveying power of the playing cards comes from the card delivery roller, the playing cards in contact with the card delivery roller are conveyed to continuously move forwards, the playing cards in contact with the card pressing piece are temporarily detained, and only one playing card is sent out from between the card delivery roller 304 and the card pressing piece 305. Based on the possibility that two playing cards enter the card turning box, the following embodiment can also be adopted, wherein a sensor is arranged in the card turning device or at the card outlet and used for identifying the stacking condition of a plurality of playing cards (the two playing cards cannot be identified when being completely overlapped and can be identified only when being overlapped and dislocated), when the sensor monitors the abnormal condition of identifying the stacking of the plurality of playing cards, the plurality of playing cards are returned to the card turning device and pass through the card turning and dealing processes again and only one playing card is ensured to be sent out from between the card sending roller 304 and the card pressing piece 305; the reserved playing cards go through the image recognition and card turning processes again and then enter the card dealing mechanism to be dealt again. By adopting the repeated card shuffling method combining the card distribution and the card turning, the possibility that the card turning device sends out two playing cards at the same time can be reduced to the minimum.

In this embodiment, the card pressing member 305 is a roller fixed on the card dealing pressing plate, and the protrusions are annularly arranged on the circumferential surface of the roller, so that the card dealing pressing member is not only convenient to manufacture, but also beneficial to discharging paper scraps along two sides of the annular protrusions. In another embodiment, the card pressing piece and the card dealing pressing plate can be integrally formed, and a corresponding concave-convex structure is arranged at the position of the card pressing piece corresponding to the card dealing roller. In other embodiments of the invention, the dealing rack may be integrally formed with the card-turning base.

In order to avoid the damage of playing cards and the machine failure caused by the fact that the card pressing piece is pressed on the card dealing roller with great pressure, a card pressing limiting mechanism for limiting the moving range of the card pressing piece is arranged, the card pressing limiting mechanism can be a waist-shaped hole structure or an upper and lower limiting stop structure arranged on the card turning seat or the card dealing support, two ends of the card pressing piece are limited by the waist-shaped hole structure or the upper and lower limiting stop structure, in the embodiment, the mahjong tile pressing limiting mechanism comprises rolling wheels arranged at two ends of a mahjong tile dealing roller 304 and bearings arranged at two ends of a mahjong tile pressing piece 305, the rolling wheels of the mahjong tile dealing roller are arranged at two ends of a roller shaft of the mahjong tile dealing roller, the bearings are arranged on shafts at two ends of the mahjong tile pressing piece 305, the rolling wheels of the mahjong tile dealing roller are abutted against and in rolling contact with the bearings of the mahjong tile pressing piece, therefore, through the abutting fit of the bearing and the roller, the minimum gap between the card pressing piece and the card dealing roller can be limited, and the card dealing roller has very high fit precision and running precision. The acting force exerted on the card pressing piece by the elastic mechanism can be larger so as to more accurately control the gap between the card pressing piece and the dealing roller, and in order to avoid the situation that the card pressing piece excessively retreats when a plurality of playing cards are squeezed between the card pressing piece and the dealing roller, a limiting rod for limiting the retreat of the card pressing piece 305 or the dealing pressing plate 307 is arranged on the card turning seat or the dealing support so as to limit the maximum gap between the card pressing piece and the dealing roller.

As shown in fig. 29, the card reversing base 301 is provided with a card dealing cover 311 outside the card dealing mechanism, the card dealing cover 311 limits the flight range of the playing cards delivered from the card dealing mechanism so as to prevent the playing cards from falling into the card receiving box, and the card dealing cover 311 is provided with a detecting element 312 for detecting whether the playing cards are delivered and a steel sheet 313 for guiding the flight direction of the playing cards. The steel sheet 313 is arranged at a card outlet of a card dealing mechanism of the card turning device, a playing card passing path formed by the card dealing roller 304 and the card pressing piece 305 points to the steel sheet 313, and the steel sheet 313 is in a shape for changing the flight direction of the playing card, such as an inclined shape or an arc shape. When the playing cards fly out from the card outlet, the playing cards face the steel sheet 313 according to the flight track defined by the passing path of the playing cards, after the playing cards touch the steel sheet 313, on one hand, the kinetic energy of the playing cards is reduced, and on the other hand, the flight direction of the playing cards is guided to face the card receiving box, so that the situation that the playing cards cannot fall into the card receiving box is avoided.

In the operation process of the poker machine and the game process of a player, a large amount of static electricity is generated, the static electricity is a reason that the upper and lower poker cards cannot be separated and processed due to large adhesive force, meanwhile, the static electricity can cause parts such as a sensor to be polluted and invalid, and in the process that the poker cards are sent out from the card dealing mechanism and fly, the poker cards with the static electricity tend to drift due to electric field force and cannot fall into the card receiving box, therefore, in the embodiment, the card pressing piece 305 is preferably made of a conductive metal material, and the card pressing piece 305 is grounded to eliminate the static electricity on the poker cards.

The card dealing device 4 comprises a card dealing mechanism arranged outside a card outlet of the card turning box 309, and a plurality of card receiving boxes for receiving the playing cards sent by the card dealing mechanism are distributed along the same circumference and move along the circumference. The dealing mechanism is positioned in the rotating circumference of the card receiving box, and the card outlet direction of the dealing mechanism is consistent with the radial direction of the rotating circumference of the card receiving box. The multiple card receiving boxes are fixed on a rotating ring, and the rotating ring is in transmission connection with the motor.

Preferably, the table top 1 of the rack is provided with three positioning wheels along the same circumference, and the rotating ring is suspended in the middle of the three positioning wheels and is in rolling friction contact with the three positioning wheels. The rotating ring is provided with internal teeth, and is in transmission connection with the mahjong splitting motor gear. The rotating ring is provided with magnetic steel and a baffle plate for positioning and identifying the card receiving boxes, the rack surface is provided with corresponding magnetic steel detection elements and baffle plate detection elements, the control module controls the card distributing motor to distribute playing cards to each card receiving box at random, and the control module records the card receiving quantity of each card receiving box to finally complete the random card dealing process.

The dealing device, the further arrangement of the card receiving box and the specific dealing process can be referred to patent document with publication number CN103083896A and related patent application of the inventor.

The card lifting device 5 and the card lifting process are referred to patent documents with publication numbers CN103055500A and CN103170131A and related patent applications of the inventor. As shown in fig. 30 to 33, the present embodiment is an improvement of a card lifting device disclosed in CN103055500A, and the card lifting device includes a card lifting base 51, a card supporting plate 52 movably disposed on the card lifting base 51, and a driving component for driving the card supporting plate 52 to move up and down. The drive assembly comprises a lifting motor and a lifting belt 54 connected to the output end of the lifting motor and positioned by a belt wheel; the end part of the card supporting plate 52 is provided with a base plate 55 connected to a lifting belt 54; when in use, the driving motor drives the lifting belt 54 to operate, so as to drive the card supporting plate 52 to move. However, in further production practice, it is found that the connection between the base plate 55 and the lifting belt 54 is a plane connection, and when the card supporting plate 52 is lifted to the highest position or lowered to the lowest position, the lifting belt 54 at the two stations is positioned by the pulleys to be an arc-shaped plane rather than a vertical plane, so that the card supporting plate 52 cannot move to the theoretically ideal highest position or lowest position (mainly, there are problems that the angle of the card supporting plate 52 can be changed and the connection surface is easy to stretch and break). In order to overcome the above disadvantages, in the embodiment, the adopted lifting belt 54 is not an integrally closed loop belt body, both end portions of the lifting belt 54 are respectively provided with a first tongue portion 541 and a second tongue portion 542 extending outwards in the belt body direction, the first tongue portion 541 and the second tongue portion 542 are integrally formed with the belt body of the lifting belt 54, and the width of the first tongue portion 541 and the second tongue portion 542 is smaller than the width of the belt body, preferably, the first tongue portion 541 and the second tongue portion 542 are in a complementary shape, and the sum of the widths of the first tongue portion 541 and the second tongue portion 542 is equal to the belt body width of the lifting belt 54, so that the lifting belt 54 adopted in the present scheme can be obtained by cutting the whole conventional integrally closed lifting belt. Furthermore, the first tongue 541 of the lifting belt 54 is drawn downward from the upper side of the base plate 55, and the tongue end thereof is fixedly connected to the lower end of the base plate 55, and the second tongue 542 of the lifting belt 54 is drawn upward from the lower side of the base plate 55, and the tongue end thereof is fixedly connected to the upper end of the base plate 55, that is, the first tongue 541 and the second tongue 542 of the lifting belt 54 are respectively connected to the base plate 55, thereby ensuring the connection strength between the lifting belt 54 and the base plate 55. Further, since the connection ends between the first tongue 541 and the second tongue 542 and the base plate 55 are relatively independent, there is no inclination when the base plate 55 is raised to the highest position or lowered to the lowest position, and the problem that the card supporting plate 52 cannot be raised to the highest position or lowered to the lowest position in the prior art is overcome. As shown in fig. 32, when the lifting belt 54 pulls the card supporting plate 52 to move upward, the tongue end of the first tongue 541 serves as a connection force applying end, and the tongue end of the first tongue 541 is connected with the lower end of the base plate 55, so that the card supporting plate 52 can be lifted to the highest position; as shown in fig. 33, when the lifting belt 54 pulls the card support plate 52 downward, the tongue end of the second tongue portion 542 serves as a connection force applying end, and the tongue end of the second tongue portion 542 is connected to the lower end portion of the base plate 55, so that the card support plate 52 can be lifted to the lowest position.
