Description

Technical Field

[0001] The invention belongs to the technical field of mahjong machine entertainment equipment, and in particular relates to a card supply device and a mahjong machine. Background Art

[0002] A mahjong machine is an entertainment device that can facilitate multiple users to play games at the same time, eliminating the need for users to shuffle or stack cards, giving users a better gaming experience. A mahjong machine usually has a shuffling mechanism for shuffling mahjong tiles, and multiple loading mechanisms for stacking shuffled mahjong tiles and placing them on a table for multiple users to use. There are generally four sets of loading mechanisms, and each set of loading mechanisms usually includes a card supply device for absorbing mahjong tiles from the shuffling tray of the shuffling mechanism and transporting them a certain distance, a card stacking device for receiving mahjong tiles from the card supply device and stacking two mahjong tiles up and down into a pile of tiles, a card storage device for storing piles of tiles, and a card pushing device and a card lifting device for cooperating with each other to push the stored pile of tiles onto the table.

[0003] Among them, for the card supply device, the currently commonly used structure includes a card suction wheel embedded with a magnet, a belt mounted on the card suction wheel, a transmission structure and a motor for driving the belt to rotate and synchronously driving the card suction wheel to rotate, and a frame for installing the above components. After the mahjong tiles are absorbed by the card suction wheel, they move with the belt and are transported to the card stacking device. In such a structure, since the mahjong tiles frequently hit the belt when the card suction wheel absorbs the mahjong tiles, the belt is prone to premature aging or even cracking. At the same time, the belt is prone to deviation due to the impact. Therefore, after using it for a period of time, in order to ensure the entertainment experience, the synchronous belt needs to be checked, and if necessary, the position of the belt needs to be corrected or a new synchronous belt needs to be replaced.

[0004] However, due to the size of the room where the mahjong machine is placed and the need for multiple users to play mahjong, the size of the mahjong machine should not be too large. The card loading mechanism usually adopts a very compact structural design, and the components of the card supply device and other components of the card loading mechanism are installed on the same frame. Therefore, it is very inconvenient and time-consuming to check the belt assembly, correct the position, and replace the synchronous belt. When users disassemble the mahjong machine to check and replace the belt, the compact structure of the card loading mechanism can easily affect or even damage other components, causing trouble and distress to users.

[0054] Fig.10 2 is a three-dimensional diagram of the card suction wheel in this embodiment. Fig.11 It is a stereoscopic diagram of the card suction wheel at different angles in this embodiment.

[0055] like Fig.10 and Fig.11 As shown, the card absorbing wheel 11 comprises a coaxially arranged card absorbing wheel driven gear portion 111 and a card absorbing wheel body portion 112, and a circle of card limiting flanges 113 are arranged between the card absorbing wheel gear portion 111 and the card absorbing wheel body portion 112. The card absorbing wheel 111 also comprises a plurality of magnet mounting portions 114 arranged inside the card absorbing wheel 111.

[0056] The card suction wheel gear part 111 is gear-shaped and meshes with the driving gear 15.

[0057] The card-absorbing wheel body 112 is cylindrical, and is composed of three spaced-apart flat portions 1121 and three arc-shaped portions 1122. The flat portion 1121 is rectangular, and its size matches the size of the mahjong tiles 200, and the sizes of the three flat portions 1121 are the same; the arc-shaped portion 1122 is an arc-shaped plate, connected between two adjacent flat portions 1121, and is in an arc shape that bulges radially outward.

[0058] The card limiting flange 113 is annular, protruding outwardly from between the card suction wheel gear portion 111 and the card suction wheel body portion 112 along the radial direction of the card suction wheel 111, and is used to limit the mahjong cards 200 adsorbed on the card suction wheel 11 to prevent the mahjong cards 200 from deviating to the side of the card supply motor 14.

[0059] The magnet mounting portion 114 is in the shape of a flat rectangular block with missing corners and is arranged on the inner side of the flat plate portion 1121.

The synchronous belt driving wheel 131, the first synchronous belt driven wheel 132, and the second synchronous belt driven wheel 133 form a triangular arrangement. The axial directions of the synchronous belt driving wheel 131, the first synchronous belt driven wheel 132, and the second synchronous belt driven wheel 133 are consistent, and are also consistent with the axial direction of the card supply wheel 11, and are all in the same horizontal direction. The card supply synchronous belt 134 is mounted on the synchronous belt driving wheel 131, the first synchronous belt driven wheel 132, and the second synchronous belt driven wheel 133 and is tensioned, and can rotate under the drive of the synchronous belt driving wheel 131. Seen from the side, the card supply synchronous belt 134 forms a triangular ring, and a section between the first synchronous belt driven wheel 132 and the second synchronous belt driven wheel 133 is a straight line, which is a card supply conveying section 1341 for carrying and conveying mahjong tiles 200.

[0066] That is, in this embodiment, the card supplying synchronous belt 134 is disposed between the card suction wheel 11 and the card stacking block 21 , and is no longer mounted on the card suction wheel 11 .

[0067] The first synchronous belt driven wheel 132 is in the shape of a long column as a whole, and has two driven wheel bodies 1321 on both sides of the axial direction. The structure of the driven wheel body 1321 is basically the same as that of the synchronous belt wheel in the prior art. A plurality of synchronous belt teeth 13211 are distributed on its periphery, and a tooth groove is formed between two adjacent synchronous belt teeth 13211. In this embodiment, the structure and size of the two driven wheel bodies 1321 are the same, and each synchronous belt tooth 13211 is aligned in the axial direction. The middle part of the first synchronous belt driven wheel 132 in the axial direction is in the shape of an oblate cylinder, and the radius of this part is equal to or greater than the radius at the tooth tip of the synchronous belt tooth 13221. Therefore, a circle of guide protrusions 1322 protruding outward in the radial direction relative to the tooth grooves on the periphery is formed in the middle part of the first synchronous belt driven wheel 132 in the axial direction. The width of the guide protrusion 1322 is about 1 / 5 to 1 / 4 of the axial length of the first synchronous belt driven wheel 132.

[0068] The structure and size of the second synchronous belt driven pulley 133 are the same as those of the first synchronous belt driven pulley 132 , and thus will not be described again.

[0069] In this embodiment, two synchronous belt driven wheels are provided in the synchronous belt assembly 13. Optionally, synchronous belt driven wheels with similar structures can also be appropriately provided at other positions to better guide the card supply synchronous belt 134, so that the movement of the card supply synchronous belt 134 is smoother.

[0070] The synchronous belt driving wheel 131 includes a synchronous belt driven gear portion 1311, an extension portion 1312 and a driving wheel body portion 1313 which are coaxially arranged in sequence. In addition, a circle of synchronous belt limiting flanges 1314 are formed at both axial ends of the driving wheel body portion 1313. The synchronous belt wheel gear portion 1311 is gear-shaped and meshes with the driving gear 15, and the synchronous belt wheel gear portion 1311 and the card suction wheel gear portion 1111 are respectively located on both sides of the driving gear 15. The extension portion 1312 is cylindrical, and its diameter is smaller than that of the synchronous belt wheel gear portion 1311. The axial length of the extension portion 1312 can be set to make the card supply synchronous belt 134 relatively farther away from the card supply motor 14, so as to match the position of the card supply wheel 11. The structure of the driving wheel body 1313 is also basically the same as that of the synchronous belt wheel in the prior art. The outer periphery thereof has a plurality of synchronous belt teeth 13131, and the cross-sectional shape and size of the synchronous belt teeth 13131 in the axial direction are the same as the cross-sectional shape and size of the synchronous belt teeth 13211 on the first synchronous belt driven wheel 132. Two synchronous belt limiting flanges 1314 protrude radially outward relative to the driving wheel body 1313, and are in the shape of two parallel circular rings. The spacing between the two synchronous belt limiting flanges 1314 is slightly larger than the width of the card supply synchronous belt 134, and the protruding distance of the synchronous belt limiting flanges 1314 (i.e., the width of the circular ring) is larger than the thickness of the card supply synchronous belt 134, thereby limiting the card supply synchronous belt 134 during the rotation of the card supply synchronous belt 134, and preventing the card supply synchronous belt 134 from running off in the axial direction of the synchronous belt driving wheel 131.

[0071] The card supply synchronous belt 134 is a synchronous belt, and the middle part of its inner surface in the width direction has a circle of guide grooves 1341 that match the guide protrusions 1322, and the two sides of the inner surface in the width direction respectively have a plurality of matching tooth grooves (not shown in the figure) that match the synchronous belt teeth 13211. The guide protrusions 1322 in the middle of the first synchronous belt driven wheel 132 and the second synchronous belt driven wheel 133 are respectively embedded in the guide grooves 1341, so as to guide the card supply synchronous belt 134 during the rotation of the card supply synchronous belt 134, and prevent the card supply synchronous belt 134 from running off in the axial direction of the first synchronous belt driven wheel 132 and the second synchronous belt driven wheel 133.

[0072] In this embodiment, a plurality of card-attracting magnets are installed on the card-attracting wheel 11, and the mahjong tiles 200 are all inlaid with magnetic materials that can be mutually attracted to the shuffling magnets. When the card-attracting wheel 11 rotates under the drive of the card-supplying motor 14, the card-attracting magnets rotated to the downward position can absorb the mahjong tiles 200 below, and the mahjong tiles 200 are driven to the top of the card-attracting wheel 11 as the card-attracting wheel 11 continues to rotate, and then transferred from the card-attracting wheel 11 to the card-supplying synchronous belt 134 on the side, and transported to the stacking device 20 by the card-supplying synchronous belt 134.

[0073] like Fig. 9 As shown, the first synchronous belt driven wheel 132 is arranged on one side of the card suction wheel body 112 and is arranged close to the upper end of the card suction wheel body 112, so that the upper surface of the card supply conveying section 1341 of the card supply synchronous belt 134 close to the receiving end 1341a of the card suction wheel body 112 is roughly flush with the upper end of the card suction wheel body 112, so that the mahjong tiles 200 can be smoothly received from the upper end of the card suction wheel body 112. The spacing between the first synchronous belt driven wheel 132 and the upper end of the card suction wheel body 112 is less than half the width of a mahjong tile 200.

[0074] The installation height of the second synchronous belt driven wheel 133 is slightly higher than the installation height of the first synchronous belt driven wheel 132, so that the upper surface height of the delivery end 1341b of the card supply synchronous belt 134 away from the card suction wheel body 112 is higher than the upper surface height of the receiving end 1341a, and the card supply conveying section 1341 is slightly inclined, and its inclination angle relative to the horizontal direction is 3°~8°, thereby avoiding the mahjong tiles 200 from unexpected sliding or rolling along the card supply synchronous belt 134 due to the fast conveying speed during the conveying process, so that the conveying of the mahjong tiles 200 is more stable.

[0075] The second synchronous belt driven wheel 133 is arranged on one side of the stacking block 21 and is approximately arranged at the first stacking height, so that the end of the card supply conveying section 1341 close to the stacking block 21 is approximately flush with the upper surface of the stacking block 21 located at the first stacking height, and the spacing between the second synchronous belt driven wheel 133 and the stacking block 21 is less than half the width of a mahjong tile 200, so that a mahjong tile 200 can be smoothly conveyed to the stacking block 21 located at the first stacking height. Afterwards, when the stacking block 21 drops to the predetermined second stacking height, the end of the card supply conveying section 1341 close to the stacking block 21 is approximately flush with the upper surface of the mahjong tile 200 on the stacking block 21 located at the second stacking height, so that another mahjong tile 200 can be smoothly conveyed to the top of the mahjong tile 200 to form a stack of tiles.

[0076] And, if Figure 4 As shown, the synchronous belt assembly 13, the card supply motor 14, and the driving gear 15 are all fixed on the card supply rack 12, and the card supply rack 12 can be detachably mounted on the lower frame 106 and one end of the card lifting carrier 60, that is, the card supply device 10 can be assembled into the card loading mechanism 101 as an integral module, or can be disassembled from the card loading mechanism 101 as an integral module for maintenance or overall replacement.

[0077] Moreover, if Figure 4As shown, when the card supply device 10 is disassembled as an integral module, most of the card supply timing belt 134 (except the portion other than the card supply conveying section 1341), a portion of the card suction wheel 11, the timing belt driving wheel 131, the driving gear 15, etc. are all accommodated inside the card supply rack 12, and the card suction wheel 11 is covered and protected by the card suction wheel cover 16. Therefore, during and after the disassembly process, the components in the card supply device 10 are not easily damaged or subjected to relative position displacement, etc.

[0078] Functions and Effects of the Embodiments

[0079] According to the card supply device and mahjong machine provided in this embodiment, the card supply device includes a card supply frame, a card suction wheel, a synchronous belt assembly, a card supply driver and a driving gear, wherein, since the card supply frame is detachably mounted on the card lifting support frame of the card lifting device, and the other components of the card supply device are arranged on the card supply frame, the card supply device can be installed or disassembled as an integral module, so that the condition of the card supply synchronous belt therein can be conveniently checked, the position of the card supply synchronous belt can be corrected, or another card supply device can be replaced as a whole, making the inspection and maintenance of the components in the card supply device more convenient. In addition, since the synchronous belt assembly is arranged between the card suction wheel and the card stacking device, that is, the card supply synchronous belt therein is no longer mounted on the card suction wheel, but receives mahjong cards from the card suction wheel, it can avoid the card supply synchronous belt from being hit when the mahjong cards are sucked, thereby increasing the service life of the card supply synchronous belt, reducing the frequency of checking and replacing the synchronous belt, and also avoiding the card supply synchronous belt from being hit by the mahjong cards and deviating, thus avoiding the noise caused by the deviation of the synchronous belt, interfering with the normal operation of other components in the card loading mechanism, and other problems. In addition, one end of the card suction wheel and one end of the synchronous belt driving wheel are both set as gear parts, and are respectively meshed with the driving gear from both sides. Therefore, the card suction wheel and the synchronous belt assembly can be synchronously driven by the same card supply driver and driving gear, so that the running speeds of the two are basically the same, so that the card supply synchronous belt can stably receive mahjong cards from the card suction wheel, and there is no need to set up drivers for the two separately, which can avoid increasing the number of components for this purpose, so that the card supply device can maintain a small number of components and a compact structure.

[0080] In the embodiment, the middle part of the two synchronous belt followers of the synchronous belt assembly has a guide protrusion, and the inner surface of the synchronous belt has a circle of guide grooves matching the guide protrusion. Therefore, the cooperation between the guide protrusion and the guide groove can play a guiding and limiting role in the axial direction of the synchronous belt driven wheel, further avoiding the deviation of the synchronous belt, thereby extending the service life of the synchronous belt and ensuring that the card supply device can work stably for a long time.

[0081] Furthermore, the two synchronous belt driven wheels are synchronous belt pulleys, the synchronous belt driving wheel also has a synchronous belt pulley part, and the card supply synchronous belt is a corresponding synchronous belt pulley. Therefore, the mahjong cards are transported with high accuracy and can achieve good transport coordination with the card suction wheels and stacking blocks on both sides.

[0082] Furthermore, the width of a circle of guide protrusions is only 1 / 5 to 1 / 4 of the axial length of the driven wheel of the synchronous belt. The guide groove is located in the middle of the width direction of the card supply synchronous belt and the width of the guide groove is also significantly smaller than the width of the card supply synchronous belt. Therefore, while the guide protrusions and guide grooves play a guiding and limiting role, their setting will not affect the normal operation of the synchronous belt.

[0083] Furthermore, synchronous belt limiting flanges are respectively provided at both ends of the driving wheel body of the synchronous belt driving wheel, and their width is greater than the thickness of the card supply synchronous belt, so that the card supply synchronous belt can be clamped in the width direction to further prevent the card supply synchronous belt from running off.

[0084] Furthermore, the first synchronous belt driven wheel is arranged close to the upper end of the card suction wheel body of the card suction wheel, and the distance between the two is less than half the width of the mahjong tiles, so the card supply synchronous belt can stably receive the mahjong tiles from the card suction wheel, and there will be no unstable phenomena such as the mahjong tiles getting stuck between the two or deflecting between the two. Similarly, since the second synchronous belt driven wheel is arranged close to the upper end of the stacking block, and the distance between the two is less than half the width of the mahjong tiles, the card supply synchronous belt can stably transport the mahjong tiles to the stacking block, and there will be no unstable phenomena such as the mahjong tiles getting stuck between the two or deflecting between the two.

[0085] Furthermore, since the installation height of the second synchronous belt driven wheel is higher than the installation height of the first synchronous belt driven wheel, the card supply conveying section of the card supply synchronous belt between the two is arranged to be slightly inclined upward along its conveying direction, which can avoid the mahjong cards on this section from sliding forward or rolling when the conveying speed is relatively fast, thereby making the mahjong card conveying more stable.

[0086] In the embodiment, a card suction wheel cover made of wear-resistant material is mounted on the card suction wheel, and the card suction wheel cover covers the entire outer circumference of the card suction wheel body and fits on the surface of a circle of card limiting flanges. Therefore, when sucking mahjong tiles, the front and one side of the mahjong tiles are in contact with the card suction wheel cover, but not in contact with the card suction wheel itself. Therefore, the card suction wheel cover can buffer and protect the card suction wheel, avoiding the collision of the mahjong tiles with the card suction wheel and damaging the surface of the wheel body when sucking the mahjong tiles, thereby causing problems such as unstable suction of the mahjong tiles. After a long period of use, if the card suction wheel cover is subject to a certain amount of wear, the card suction wheel cover can be replaced alone without replacing the card suction wheel, making subsequent maintenance more convenient and low-cost.

[0087] Furthermore, the card absorbing wheel body has multiple flat parts, the card absorbing wheel cover has uniform thickness, and the outer surface of the card absorbing wheel cover covering the flat part is basically flat, so the setting of the card absorbing wheel cover does not affect the adsorption effect of the card absorbing wheel on mahjong cards.

[0088] In the embodiment, the card supply rack includes a card supply main frame body and a component protection plate fixed thereon, the card supply main frame body is provided with connected circular grooves and special-shaped grooves, the card supply wheel gear portion of the card supply wheel is accommodated in the circular groove, the driving gear and the driving wheel gear portion of the synchronous belt driving wheel are accommodated in the special-shaped groove, the component protection plate shields the driving gear, the two gear portions and most of the card supply synchronous belt so that they are located inside the card supply rack, thereby being able to protect these components, so that the card supply device has better integrity, during the process of disassembling the card supply device and after it is disassembled, the components in the card supply device are not easily damaged, and the components are not easily displaced, which can make the inspection and maintenance of the card supply device more convenient and quick.

[0089] Furthermore, the card supply device has a plurality of fixing holes corresponding to the fixing holes on the card lifting carrier frame, and one end of the card supply device has a card slot and a snap-in protrusion matching the mounting structure on the lower frame. The card supply device only needs to be snap-in and embedded as an integral module and then installed with a number of fasteners. Similarly, it can be easily disassembled as an integral module. Therefore, the assembly and disassembly of the card supply device are very simple, and the joint is firmly bonded after assembly.

[0090] In addition, in the embodiment, a synchronous belt with a toothed surface or a grooved surface is used to transport mahjong tiles instead of a belt. Compared with the traditional solution of using a belt to transport mahjong tiles, its function, operation, motor force, friction adhesion during transportation of mahjong tiles, durability, etc. are superior to the traditional belt solution, thereby further improving the performance and service life of the card supply device.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
