Description

Technical Field

[0001] This utility model belongs to the field of mahjong entertainment equipment, and relates to mahjong machines, and more particularly to a shuffling mechanism for shuffling mahjong tiles in a mahjong machine and a shuffling plate in the shuffling mechanism. Background Technology

[0002] Mahjong machines typically have a shuffling tray in their shuffling mechanism. When the user inputs a shuffling command, the control panel located in the center of the mahjong table rises, creating a window between the control panel and the table for the mahjong tiles to be pushed in. The user pushes the mahjong tiles through this window, and they fall onto the shuffling tray below for shuffling.

[0003] Because mahjong tiles are usually made of plastic, which is relatively brittle and hard, they tend to generate a lot of noise when pushed and struck on the shuffling plate. Furthermore, the shuffling plate typically has multiple deflector strips. These strips, or the shuffling plate itself, rotate under the drive of a mechanism, causing the strips to move the mahjong tiles piled in the center of the plate to the edges for shuffling and easier for the loading mechanism to pick them up. During this process, the tiles collide with these strips, the shuffling plate, or each other, resulting in continuous noise throughout the shuffling process.

[0004] Existing technologies include several mahjong machines designed to reduce shuffling noise. For example, CN201921202989.9 discloses a double-layer shuffling disc device that reduces the noise of discarding tiles by placing a buffer disc above the shuffling disc or the tile-dispensing strip. CN202121094961.5 discloses a mahjong machine with noise reduction functionality, which absorbs noise by adding noise-absorbing rubber sleeves and sound-absorbing cotton boards near the shuffling disc. While these existing solutions can reduce noise to some extent, the additional components, given the limited internal space of a mahjong machine, not only occupy more space and affect the layout of other components, but also complicate the internal structure of the mahjong machine, increasing the difficulty of manufacturing and maintenance. Utility Model Content

[0005] To address the aforementioned problems, this application provides a shuffling tray, disposed in the shuffling mechanism of a mahjong machine, for receiving and carrying mahjong tiles from the push-in port on the mahjong machine table during the shuffling process. The tray is characterized by comprising: a tray body having a sliding section located below the push-in port, a stopping section disposed outside the sliding section, and a blocking section disposed at the outer edge of the stopping section; a sliding layer, at least laid on the sliding section and the stopping section; and a plurality of partition blocks, spaced circumferentially on the stopping section.

[0006] The shuffling disc provided by the present invention may also have the following technical feature: the sliding part is inclined with the part near the stop part being lower than the part away from the stop part, and the angle of inclination is 13°-45°.

[0007] The shuffling disc provided by the present invention may also have the following technical feature: the sliding layer is the rough surface layer of nylon hook and loop fastener.

[0008] The shuffling disc provided by the present invention may also have the following technical feature: the partition blocks are all made of beef tendon.

[0009] The shuffling disc provided by the present invention may also have the following technical features: the sliding part and the stopping part are provided with multiple rings of holes.

[0010] The shuffling disc provided by the present invention may also have the following technical features, wherein the sliding layer includes a first sliding layer portion laid on the sliding part and a second sliding layer portion laid on the stop part, and the sliding resistance of the first sliding layer portion is less than the sliding resistance of the second sliding layer portion.

[0011] The shuffling disc provided by the present invention may also have the following technical features: the inner part of the stop part is inclined, and the outer part is horizontal.

[0012] Furthermore, this utility model also provides a shuffling mechanism, including: a shuffling disc and a shuffling disc driving unit, wherein the shuffling disc is any of the shuffling discs described above.

[0013] The shuffling mechanism provided by this utility model may further include: a plurality of shuffling plate height adjustment units distributed circumferentially below the stopping section. Each shuffling plate height adjustment unit includes a height adjustment seat and a rolling wheel. The height adjustment seat is provided with height adjustment grooves of different depths. The rolling wheel has a wheel body and a wheel axle set on the wheel body. The wheel axle can be placed into the height adjustment grooves of different depths, so that the wheel body provides support for the stopping section at different heights.

[0014] In addition, this utility model also provides a mahjong machine, including the shuffling mechanism as described in any of the above.

[0015] Functions and effects of utility models

[0016] According to the shuffling disc, shuffling mechanism, and mahjong machine provided by this utility model, since the disc body has a sliding part located below the push-in entrance and a stopping part and a blocking part arranged outside the sliding part, when the mahjong tiles are pushed in from the push-in entrance, these mahjong tiles will slide randomly on the sliding part to the stopping part, thus shuffling the mahjong tiles. Since both the sliding part and the stopping part are covered with sliding layers (i.e., a first sliding layer and a second sliding layer are respectively laid), on the one hand, the sliding layers can buffer and reduce noise during the collision process of the mahjong tiles falling, and on the other hand, they can absorb the noise generated by the mahjong tiles as the shuffling disc rotates. Therefore, the shuffling disc of this utility model can shuffle the tiles without the need for a tile-pulling strip, and can greatly reduce noise without adding a complex structure.

Detailed Implementation

[0025] The specific implementation of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0026] <Example>

[0027] Figure 1 , Figure 2 This is a structural diagram of a mahjong machine according to an embodiment of the present invention.

[0028] like Figure 1-2 As shown, this embodiment provides a mahjong machine 100 for automatically shuffling and loading mahjong tiles 200, including a tile loading mechanism 101, an operation panel mechanism 102, a table frame mechanism 103, and a shuffling mechanism 107.

[0029] The table frame mechanism 103 includes an outer frame 104, a tabletop 105 mounted on the outer frame 104, and a table base 106 supporting the tabletop 105 and other mechanisms. The bottom of the table base 106 is provided with table legs for support on the ground, and the middle of the tabletop 105 is provided with a push-in slot 1051 for the user to push in mahjong tiles 200 when shuffling is required. Figure 1 , Figure 2 Table legs were omitted in all of them. Figure 2 The outer frame 104 and the tabletop 105 are further omitted.

[0030] Figure 3 This embodiment of the utility model omits the structural diagram of the mahjong machine with the card-adding mechanism.

[0031] like Figure 1-3As shown, the control panel mechanism 102 is located in the middle of the tabletop 105 and is used for users to input operation commands. It has a control panel 1021 that can be raised and lowered. The control panel 1021 is adapted to the shape of the push-in port 1051. When it is not raised, it closes the push-in port 1051. When it is raised, it exposes the push-in port 1051, allowing the user to push the mahjong tiles 200 in.

[0032] The shuffling mechanism 107 is used to receive and shuffle the mahjong tiles 200 after use. It includes a shuffling plate 71, a shuffling plate mounting unit for mounting the shuffling plate 71, a shuffling plate driving unit for driving the shuffling plate 71 to rotate, and a shuffling plate height adjusting unit for adjusting the height of the shuffling plate 71.

[0033] Figure 4 This is a structural diagram of the shuffling disc of this utility model as viewed from the top. Figure 5 This is a structural diagram of the shuffling disc of this utility model when viewed from the bottom.

[0034] like Figure 4-5 As shown, the shuffling disk 71 includes a disk body 711, a sliding layer 712, and multiple partition blocks 713.

[0035] The disc body 711 has a sliding part 7111, a stop part 7112, and a stop part 7113.

[0036] The sliding section 7111 is shaped like a truncated cone, approximately like a conical hat, and is located below the push-in port 1051. It is used to receive the mahjong tiles 200 falling from the push-in port 1051 and allow these mahjong tiles 200 to slide on it. The middle part of the sliding section 7111 is used to connect with the shuffling plate mounting unit, and is provided with a bearing seat 7114 that is recessed downward to form an annular groove.

[0037] In this embodiment, the upper surface of the sliding part 7111 is inclined, that is, in the normal installation and use state, the height of the outer part of the sliding part 7111 is lower than the height of the part far from the inner side, and the angle of inclination is 30°.

[0038] The stop plate portion 7112 is connected to the outside of the sliding portion 7111, extending outward in a roughly horizontal direction around the sliding portion 7111 to form a ring. In this embodiment, the upper surface of the inner part of the stop plate portion 7112 (i.e., the part connected to the sliding portion 7111) has a small inclination, while the outer part does not have an inclination and is horizontal.

[0039] The blocking part 7113 is located on the outer edge of the stop part 7112, and extends upward from the outer edge to form a ring.

[0040] In this embodiment, the disc body 711 is integrally formed, that is, the sliding part 7111, the stop part 7112, the stop part 7113, the bearing seat part 7114, and the reinforcing rib 7115 are integrally formed.

[0041] like Figure 5 As shown, the outer wall of the bearing seat 7114 is also provided with a plurality of reinforcing ribs 7115. Each reinforcing rib 7115 is roughly triangular in shape, extends outward from the outer wall surface of the bearing seat 7114, and its upper end is connected to the lower surface of the sliding part 7111.

[0042] In addition, the sliding part 7111 and the stop part 7112 of this embodiment are provided with multiple rings of holes 7116. The spacing between each ring of holes 7116 is approximately the same, and the multiple holes 7116 in each ring are distributed approximately evenly along the circumference, so that holes 7116 are densely distributed in all places on the sliding part 7111 and the stop part 7112.

[0043] The sliding layer 712 is laid on the sliding part 7111 and the stop part 7112. For example... Figure 3-4 As shown, the sliding layer 712 in this embodiment is divided into multiple block-shaped components, including multiple first sliding layer portions 7121 laid on the sliding portion 7111 and multiple second sliding layer portions 7122 laid on the stop portion 7112, wherein the number of first sliding layer portions 7121 and second sliding layer portions 7122 is the same (8 each) and they correspond one-to-one.

[0044] The first sliding layer 7121 is curved and fan-shaped, with its inner edge being arc-shaped and fitting against the outer side of the bearing seat 7114. Its outer edge is an arc with a larger diameter and is located at the junction of the sliding section 7111 and the stop section 7112. Each first sliding layer 7121 is curved to the same side along the circumferential direction, and the side edges of adjacent first sliding layers 7121 match, resulting in a uniform arrangement of multiple spiral lines in the gaps between the first sliding layers 7121. Furthermore, in this embodiment, the placement of the first sliding layers 7121 is appropriately set so that the gaps between the first sliding layers 7121 and the holes 7116 do not overlap, i.e., the holes 7116 do not protrude from the gaps.

[0045] The second sliding layer 7122 is fan-shaped, with its inner edge located at the junction of the sliding section 7111 and the stopping section 7112, corresponding to the outer edge of the first sliding layer 7121, and having a certain gap between them. The outer edge of the second sliding layer 7122 extends to the blocking section 7113 and contacts it. Furthermore, in this embodiment, similar to the placement of the first sliding layer 7121, the placement of the second sliding layer 7122 is also appropriately set so that the gaps between the second sliding layers 7122 and the holes 7116 do not overlap. Additionally, the gaps between the first sliding layers 7121, the gaps between the second sliding layers 7122, and the gaps between adjacent first and second sliding layers 7121 are all smaller than the width of the mahjong tile 200, avoiding the problem of the mahjong tile 200 getting stuck.

[0046] Both the first sliding layer 7121 and the second sliding layer 7122 are made of composite fiber material fabric. In this embodiment, they are made of the napped surface layer of nylon hook and loop fasteners.

[0047] In addition, in this embodiment, the sliding resistance of the first sliding layer 7121 is less than that of the second sliding layer 7122. For example, a more tightly woven or smoother textured material can be used, or a material with a low coefficient of friction can be used, or a resistance coating can be added to the second sliding layer 7122.

[0048] There are eight partition blocks 713, which are evenly distributed circumferentially on the outer part of the stop plate section 7112. In this embodiment, the eight partition blocks 713 are located between the gaps of two adjacent second sliding layers 7122, and the two side edges of each second sliding layer 7122 are also provided with notches corresponding to the partition blocks 713, so that the partition blocks 713 can be exposed.

[0049] In addition, in this embodiment, each of the partition blocks 713 is a "beef tendon block", that is, made of rubber or plastic material with a certain elasticity, which can block the mahjong tiles 200 for shuffling, and at the same time reduce collision noise.

[0050] Figure 6 yes Figure 3 The structural diagrams of the shuffling plate and the control plate are omitted.

[0051] like Figure 3 , Figure 6 As shown, the shuffling disc mounting unit includes a disc mounting base 721, a bearing 722, and a fixing cap 723.

[0052] The disc mounting base 721 is approximately cylindrical, with its bottom end fixedly mounted on the table base 106. The upper end is provided with a first external thread 7211 and a second external thread 7212 from top to bottom. The outer diameter of the first external thread 7211 is smaller than that of the second external thread 7212. The first external thread 7211 is used to install a height limiting sleeve 1022 located below the operating disc 1021 and used to limit the descent position of the operating disc 1021.

[0053] The bearing 722 is sleeved in the middle of the disc mounting base 721. Its inner ring is adapted to and interference-fitted with the outer surface of the disc mounting base 721, and its outer ring is adapted to and interference-fitted with the inner surface of the bearing housing portion 7114, thereby allowing the disc body 711 to be rotatably sleeved on the disc mounting base 721.

[0054] like Figure 3 As shown, the fixing cap 723 is a hollow frustoconical shape and is located above the shuffling disc 71. The inner surface of the fixing cap 723 has an internal thread, which is used to connect with the second external thread portion 7212 and thus install it on the disc mounting base 721. The lower surface of the fixing cap 723 abuts against the upper surface of the inner ring of the bearing 722, thereby pressing the bearing 722 into the bearing housing portion 722 so that it is not easily loosened.

[0055] The shuffling disc drive unit includes a shuffling motor 731, a shuffling output gear 732, a shuffling input gear ring 733, and an auxiliary gear 734.

[0056] The shuffling motor 731 is fixedly mounted on the table base 106. Specifically, the table base 106 has a downward recess in the middle, and its size is slightly larger than the shuffling disk 71, so that the shuffling disk 71 can be accommodated in the recess. The bottom of the recess is a support plate 1061, and the shuffling motor 731 is fixedly mounted below the support plate 1061, with its output axis passing upward through the support plate 1061.

[0057] The shuffling output gear 732 is mounted on the output end of the shuffling motor 731, located below the shuffling disk 71.

[0058] like Figure 5 As shown, the lower surface of the sliding part 7111 is provided with a ring of teeth, namely the shuffling input ring 733. The shuffling output ring 733 is distributed in a ring around the bearing housing part 7114. The shuffling output gear 732 meshes with the shuffling input ring 733, so that the shuffling motor 731 can drive the shuffling disk 71 to rotate through the meshing relationship between the two.

[0059] In this embodiment, there are two auxiliary gears 734, each mounted on the table base 106 via a gear mounting bracket. The gear mounting bracket has a rotating shaft, on which the auxiliary gear 734 is rotatably mounted and meshes with the shuffling input gear ring 733. The two auxiliary gears 734 and the shuffling output gear 732 are arranged at equal intervals in the circumferential direction (i.e., 120° apart). Through the meshing of the two auxiliary gears 734 with the shuffling input gear ring 733, the rotation of the shuffling disk 71 can be made smoother and more stable.

[0060] Several shuffling plate height adjustment units 74 are evenly distributed circumferentially below the stop section 712.

[0061] Figure 7 This is a structural diagram of the shuffling plate height adjustment unit in this embodiment.

[0062] like Figure 7 As shown, the shuffling plate height adjustment unit includes a height adjustment seat 741 and a roller 742.

[0063] The height adjustment seat 741 is fixed on the support plate 1061 and has a pair of spaced-apart seat plates 7411. Each seat plate 7411 has three height adjustment grooves 7412 of the same width but decreasing depth on its inner surface (i.e., the side surface facing the other seat plate 7411). The height adjustment grooves 7412 on the two seat plates 7411 are arranged opposite to each other, and the height adjustment grooves 7412 at opposite positions on the two seat plates 7411 have the same depth.

[0064] The rolling wheel 742 has a wheel body 7421 and a wheel axle 7422 disposed on the wheel body 7412. The diameter of the wheel axle 7422 is adapted to the width of the height adjustment groove 7412. The distance between the two ends of the wheel axle 7422 matches the distance between the two opposite height adjustment grooves 7412, so that it can be placed into the two opposite height adjustment grooves 7412 respectively, so that the wheel body 7412 is located between the two seat plates 7411.

[0065] The wheel 7421 contacts the lower surface of the shuffling disc 711, providing support to the stopping section 712 during the rotation of the shuffling disc 71. Since the stopping section 712 is a certain distance from the bearing seat 714, it is prone to sinking under the weight when a large number of mahjong tiles 200 are piled on it. The support provided by the wheel 7421 prevents this sinking, making it easier for the loading mechanism 101 to pick up the mahjong tiles 200 from the stopping section 712. Furthermore, when the axle 7422 is placed in height adjustment slots 7412 of varying depths, the height at which the wheel 7421 supports the stopping section 712 also varies, allowing for slight adjustments to the height of the stopping section 712. This allows for adjustment of the support height to accommodate mahjong tiles of different sizes, further facilitating the picking-up action of the loading mechanism 101.

[0066] The mahjong machine 100 of this embodiment can be used by four users simultaneously. Accordingly, it is provided with four tile-feeding mechanisms 101, which are located at the four corners of the table base 106. Each tile-feeding mechanism 101 can pick up mahjong tiles 200 from the tile-stopping section 7112, stack the tiles, and raise the stacked mahjong tiles 200 to the table for the user to use. Its specific structure and working principle can adopt existing technology, and will not be described in detail here.

[0067] The working principle of the mahjong machine 100 in this embodiment is explained below.

[0068] When the user finishes using the mahjong tiles and needs to shuffle them, they can input a command to raise the control panel 1021. The control panel 1021 will then rise to expose the push-in port 1051. After the user pushes the mahjong tiles 200 on the table into the push-in port 1051, they can input a shuffle command through the control panel 1021. The control panel 1021 will then descend, and the shuffling mechanism 107 will begin shuffling, i.e., the shuffling motor 731 will start working.

[0069] When the user pushes the mahjong tiles 200 from the table through the inlet 1051, the tiles 200 first fall onto the sliding section 711, slide down along the first sliding layer 7121, and slide in a scattered state onto the stopping section 712, where they are blocked by the blocking section 713. During this process, the blocking block 713 provides a certain degree of obstruction, allowing the mahjong tiles 200 to be distributed relatively evenly on each of the second sliding layers 7122. Thus, the mahjong tiles 200 are shuffled, and at the same time, most of the tiles 200 are located on the stopping section 712, making them available for the tile-adding mechanism 101 to pick up and add tiles.

[0070] Functions and effects of the embodiments

[0071] According to the shuffling plate, shuffling mechanism, and mahjong machine provided in this embodiment, since the plate body 71 has a sliding part 7111 located below the push-in port 1051 and a stopping part 7112 and a blocking part 7113 provided outside the sliding part 7111, when the mahjong tiles 200 are pushed in from the push-in port, these mahjong tiles 200 will slide randomly on the sliding part 7111 to the stopping part 7112, which serves to shuffle the mahjong tiles 200; since the sliding part 7111 and the stopping part 7112 are both covered with a sliding layer 712 (i.e., the first sliding layer 7121 and the second sliding layer 7122 are respectively laid), on the one hand, the sliding layer 712 can buffer and reduce noise during the process of the mahjong tiles 200 falling and colliding, and on the other hand, it can absorb the noise generated by the mahjong tiles 200 as they rotate with the shuffling plate 71.

[0072] Furthermore, since the sliding part 7111 is inclined at an angle of 30°, the mahjong tile 200 can slide from the sliding part 7111 to the stopping part 7112 at an appropriate sliding speed. This avoids both excessive collision noise caused by excessive speed and excessive speed that would cause the mahjong tile 200 to stop sliding midway due to the resistance of the sliding layer 712.

[0073] Furthermore, since the sliding part 7111 and the stopping part 7112 of this embodiment are provided with multiple rings of holes 7116, on the one hand, the weight of the disk body 711 can be reduced and molding material can be saved, and on the other hand, noise can be reflected and absorbed inside the holes 7116, thereby reducing noise. Moreover, since these holes 7116 do not overlap with the gap between the first sliding layer 7121 and the second sliding layer 7122, that is, they do not protrude from the gap, and therefore do not form recessed parts that hinder the sliding movement of the mahjong tiles 200.

[0074] Furthermore, since the inner surface of the stopping section 7112 has a slight inclination, while the outer surface is horizontal, the mahjong tile 200 continues to slide a short distance after sliding from the sliding section 7111 to the stopping section 7112 due to the inclination. This ensures that the sliding endpoint of the mahjong tile 200 is actually slightly towards the middle of the stopping section 7112. This avoids the problem of the second sliding layer 7122 being pushed by the mahjong tile 200 and wrinkled or displaced when the mahjong tile 200 reaches the sliding endpoint at the gap between the first sliding layer 7121 and the second sliding layer 7122.

[0075] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and improvements can be made to the technical solutions without departing from the spirit and scope of this utility model, and all such changes and improvements fall within the scope of protection claimed by this utility model.

[0076] For example, in one embodiment, the sliding layer 712 includes a plurality of first sliding layer portions 7121 and a plurality of second sliding layer portions 7122. However, as an alternative, in other embodiments of the present invention, the plurality of first sliding layer portions 7121 may be replaced by a single first sliding layer portion 7121 with the same overall shape, and / or the plurality of second sliding layer portions 7122 may be replaced by a single second sliding layer portion 7122 with the same overall shape. Furthermore, in another alternative, the sliding layer 712 may be a single unit, that is, the first sliding layer portions 7121 and the second sliding layer portions 7122 are together composed of a single piece of material.

[0077] In this embodiment, the sliding resistance of the first sliding layer 7121 is less than that of the second sliding layer 7122. However, in this invention, as an alternative, the sliding resistance of the first sliding layer 7121 in other embodiments may be approximately the same as or similar to that of the second sliding layer 7122.

[0078] In this embodiment, the disk body 711 is integrally formed. As an alternative, in other embodiments, the disk body 711 may also be formed from multiple separately molded pieces that are then joined together.

[0079] In this embodiment, the first sliding layer 7121 and the second sliding layer 7122 are made of the napped surface of nylon hook and loop fasteners. Alternatively, in other embodiments, they can also be made of fibrous materials with a certain thickness and fluffiness, such as felt or fleece.

[0080] In this embodiment, the tilt angle of the sliding part 7111 is 30°. Alternatively, in other embodiments, the tilt angle can be any angle between 13° and 45°, and any angle within this range can achieve essentially the same effect as the angle in this embodiment.
