The card pressing member 305 is fixed on the card dealing pressing plate 306, or is integrally formed with the card dealing pressing plate 306, 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 invention prevents the upper and lower playing cards from being electrostatically bonded and unable to be separated by matching the card dealing roller 304 with the concave-convex structure on the card pressing member 305, and because the card pressing member 305 cannot synchronously rotate with the card dealing roller 304 and the concave-convex structure has a small pressing contact area with the playing cards, the static friction force between the card pressing member and the playing cards is far greater than the friction force between the upper and lower playing cards, and the conveying power of the playing cards comes from the card dealing roller, the playing cards contacting with the card dealing roller are conveyed to continuously move forwards, the playing cards contacting with the card pressing member are temporarily detained, and only one playing card is sent out from between the card dealing roller 304 and the card pressing member 305.

In this embodiment, the card pressing member 305 is a roller fixed on the card dealing pressing plate, and the protrusions 3053 are annularly arranged on the circumferential surface of the roller, so that the processing and manufacturing are convenient, and the paper scraps can be discharged along two sides of the annular protrusion conveniently. 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 playing card damage and machine failure caused by the fact that the card pressing member presses the card dealing roller with great pressure, a card pressing limiting mechanism for limiting the moving range of the card pressing member 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, and two ends of the card pressing member are limited by the waist-shaped hole structure or the upper and lower limiting stop structure. 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 314 for limiting the retreat of the card pressing piece 305 or the dealing pressing plate 306 is arranged on the card turning seat or the dealing support and is used for limiting the maximum gap between the card pressing piece and the dealing roller.

The card-turning seat 301 is provided with a card-dealing cover 3011 outside the card-dealing mechanism, the card-dealing cover 3011 limits the flight range of the playing cards sent from the card-dealing mechanism so as to avoid the situation that the playing cards cannot fall into the card-receiving box, and the card-dealing cover 3011 is provided with a detecting element 3012 for detecting whether the playing cards are sent out.

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, as shown in fig. 1 and 2, includes a card dealing mechanism installed outside the card outlet of the card turning box 308, and a plurality of card receiving boxes 401 for receiving playing cards dealt by the card dealing mechanism are distributed along the same circumference and move along the circumference. The dealing mechanism is located in the rotation circumference of the card receiving box 401, and the card outlet direction of the dealing mechanism is consistent with the radial direction of the rotation circumference of the card receiving box 401. The card receiving boxes 401 are fixed on a rotating ring 403, and the rotating ring 403 is in transmission connection with a card distributing motor 402.

Three positioning wheels 405 are arranged on the table top 1 of the rack along the same circumference, and the rotating ring 403 is suspended in the middle of the three positioning wheels 405 and is in rolling friction contact with the three positioning wheels 405. The rotating ring 403 is provided with internal circumferential teeth, and the rotating ring 403 is in gear transmission connection with the mahjong splitting motor 402. The rotating ring is provided with a magnetic steel 407 and a baffle 404 for positioning and identifying the card receiving box 401, the rack surface is provided with a corresponding magnetic steel detection element 408 and a corresponding baffle detection element 406, 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 number of the playing cards received by each card receiving box and finally completes the random card dealing process.

An automatic poker machine, as shown in figures 1 and 2, includes: a card feeding device 2, a card turning device 3, a card dealing device 4 and a card lifting device 5, which are all arranged on the table surface 1 of the machine frame.

The card feeding device, as shown in fig. 3, 4 and 5, comprises a card feeding frame 201 for placing playing cards, and a card feeding mechanism for conveying the playing cards is arranged at the bottom of the card feeding frame 201. The card feeding frame 201 is provided with a card feeding cabin door 200. The mounting structure of the card inlet door refers to a cover plate device for a card inlet frame of a poker machine, which is disclosed in the patent document with the publication number CN 103157272B. The card feeding mechanism is a plurality of arranged conveying wheels 202, a plurality of openings used for arranging the conveying wheels 202 are formed in the bottom surface of the card feeding frame 201, the parts of the conveying wheels 202 protruding out of the openings form effective conveying surfaces, the conveying wheels 202 are in transmission connection with a card feeding motor 209, the distance between the effective conveying surfaces of the two adjacent conveying wheels 202 is smaller than the width of the playing cards, the distance between the effective conveying surface of the conveying wheel 202 close to the side wall of the card feeding frame 201 and the side wall of the card feeding frame 201 is smaller than the width of the playing cards, and the length and the width of each opening are smaller than the width of the playing cards.

The card placing bay 2011 of the card feeding frame 201 is adapted to receive a stack of substantially stacked playing cards. In order to avoid machine failure caused by disordered playing card putting of a player, the length of the playing card putting bin 2011 is larger than the length of the playing card and smaller than twice the length of the playing card, and the width of the playing card putting bin 2011 is larger than the width of the playing card and smaller than twice the width of the playing card; moreover, the side walls around the card feeding frame 201 are provided with corresponding inclined planes or cambered surfaces so that the card placing bin 2011 is gradually reduced from top to bottom, and even if the playing cards which are not orderly placed in the card feeding frame can be gradually gathered at the bottom of the card feeding frame. The card outlet of the card inlet frame 201 is arranged on one side of the bottom of the card inlet frame, the card outlet of the card inlet frame 201 is provided with a card outlet mechanism used for sending a few playing cards, and the size of the card outlet is matched with the width of the playing cards (if the playing cards are conveyed along the width direction of the playing cards, the size of the card outlet is matched with the width of the playing cards). The side wall of the large-size playing card bin 2011 close to the card outlet is transited to the small-size card outlet through an inclined surface or an arc surface so as to gradually gather the conveyed playing cards to the card outlet.

As shown in fig. 5, 6, 7 and 8, the card-out mechanism comprises a card-feeding pressing plate a203, a card-feeding roller a210, a card-feeding pressing plate B204, a card-feeding roller B211, a card-out pressing plate 205, a card-out pressing roller 206 and a card-out roller 207, wherein the card-feeding roller a210, the card-feeding roller B211 and the card-out roller 207 are arranged on the card-feeding frame 201 in parallel and are in transmission connection with a card-sending motor 209 through a gear set 208; the card feeding pressing plate A203 is fixed on the card feeding frame 201, the card feeding pressing plate A203 and the card feeding roller A210 are arranged in a vertically corresponding mode, playing cards pass through the card feeding pressing plate A203 and the card feeding roller A210, a pressing plate convex strip 2031 is arranged at the bottom of the card feeding pressing plate A203, the pressing plate convex strip 2031 and the axis of the card feeding roller A210 are staggered by a horizontal distance d, the pressing plate convex strip 2031 is closer to the card placing bin 2011 than the axis of the card feeding roller A210, the pressing plate convex strip 2031 is lower than the top of the card feeding roller A210, and a gap for the playing cards to pass through is formed between the pressing plate convex strip 2031 and the card feeding roller A210; the card feeding pressing plate B204 is fixed on the card feeding frame 201, the card feeding pressing plate B204 and the card feeding roller B211 are arranged in a vertically corresponding mode, a gap for playing cards to pass through is reserved between the card feeding pressing plate B204 and the card feeding roller B211, a plurality of annular protrusions 2111 are arranged on the card feeding roller B211, grooves A2041 corresponding to the annular protrusions 2111 are formed in the card feeding pressing plate B204, and as shown in the figure 9, the annular protrusions 2111 on the card feeding roller B211 protrude into the corresponding grooves A2041 on the card feeding pressing plate B204; the card-out pressing plate 205 is movably arranged on the card-in frame 201 and gives a downward pressing trend to the card-out pressing plate through an elastic mechanism, the card-out pressing plate 205 is provided with a card-out pressing roller 206, the card-out pressing roller 206 and the card-out pressing roller 207 are correspondingly arranged in a vertical rotating mode and clamp the playing cards between the card-out pressing roller 206 and the card-out pressing roller 207, and therefore the single playing cards are sent out from a card-out opening of the card-in device. The card sending mechanism and the card discharging mechanism share one card sending motor.

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 used to limit the card discharging height of the card discharging port of the card dealing chamber, or the card discharging height of the card discharging port of the card dealing chamber is limited by setting the upper and lower roller gaps of the upper and lower rollers, and the number of playing cards passing through the card discharging port of the card dealing chamber is limited by such a structure.

In order to solve the technical problem, the gap between the pressing plate protruding strip 2031 and the card feeding pressing plate a203 of the invention limits that only a few playing cards (at most three playing cards in the embodiment) enter, and the front-back dislocation and the top-bottom overlapping design of the pressing plate protruding strip 2031 and the card feeding pressing plate a203 (the pressing plate protruding strip 2031 and the axis of the card feeding roller a210 are staggered by a horizontal distance d, the pressing plate protruding strip 2031 is closer to the card placing cabin 2011 than the axis of the card feeding roller a210, and the pressing plate protruding strip 2031 is lower than the top of the card feeding roller a 210) are adopted, so that when the gap between the pressing plate protruding strip 2031 and the card feeding roller a210 enters a plurality of playing cards, the entering end of the playing cards can be tilted to shift the upper and lower playing cards so as to avoid the upper and lower playing cards from being electrostatically bonded and unable to be separated, because the pressing contact area of the pressing plate protruding strip is stationary and the upper playing cards is smaller, the static friction force between the upper and lower playing cards are temporarily separated, the playing cards are far larger than the playing cards below the playing cards are temporarily transported by the playing card feeding roller a transport power roller a. Although the card-holding strip 2031 and the card-feeding roller A210 already separate two overlapped playing cards, the situation that the two playing cards enter between the card-feeding pressing plate B204 and the card-feeding roller B211 successively is still inevitable, the invention prevents the upper and the lower playing cards from being deformed due to the matching of the concave-convex staggered structures on the card-feeding pressing plate B204 and the card-feeding roller B211, and the static friction force between the card-feeding pressing plate B and the playing cards above is far larger than the friction force between the upper and the lower playing cards because the card-feeding pressing plate B is static and the concave-convex structure of the card-feeding pressing plate B has smaller pressure contact area with the playing cards above, and the conveying power of the playing cards comes from the card-feeding roller B and is applied to the playing cards below, so the playing cards below are conveyed to move forwards continuously, the playing cards above are temporarily detained, and only the playing cards below are fed out from the space between the card-feeding roller B204 and the card-feeding roller B211; the delivered playing cards are clamped by the card-delivering press roller 206 and the card-delivering roller 207 and delivered to the card-flipping device.

The card feeding pressing plate a203, the card feeding roller a210, the card feeding pressing plate B204, the card feeding roller B211, the card discharging pressing plate 205, the card discharging pressing roller 206 and the card discharging roller wheel 207 are all components, each component may be an integrally formed component, or a combined component composed of a plurality of components to achieve the same function, for example, the card feeding pressing plate B204 may be an integrally formed component with a concave-convex structure, the card feeding pressing plate B204 may also be a roller component with a concave-convex ring fixed on a pressing plate component, and in another embodiment, the roller component with the concave-convex ring is mounted on the pressing plate component in a manner of extremely large rotation resistance (i.e., the roller component may rotate relative to the pressing plate component, but has large rotation difficulty and resistance).

Preferably, the card feeding pressing plate a203 is formed with an inclined surface or an arc surface on one side of the pressing plate convex strip 2031 close to the card feeding direction, so that only a few playing cards enter between the pressing plate convex strip 2031 and the card feeding roller a210 after a plurality of playing cards are separated by the blocking, and the playing card separating pressure of the card discharging mechanism is relieved. Similarly, an inclined plane or an arc surface is formed on one side of the card feeding pressing plate B204 close to the card feeding direction, so that when two or three playing cards pass through the pressing plate convex strip 2031 and the card feeding roller A210 and then are tilted upwards, the two playing cards can be further conveniently moved up and down, only one or two playing cards enter the space between the card feeding pressing plate B204 and the card feeding roller B211 through blocking, the playing card separating pressure of the card discharging 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 A203 and the card feeding pressing plate B204, that is, an upward inclined plane or an arc surface is formed behind the pressing plate convex strip, so that a plurality of playing cards passing through the pressing plate convex strip 2031 and the card feeding roller A210 can be fully tilted and thoroughly separated.
