Description

Technical Field

[0001] This utility model relates to the technical field of mahjong machines, and in particular to a card-pushing and turning mechanism and a mahjong machine. Background Technology

[0002] Fully automatic mahjong machines can achieve automated tile stacking. The stacked tiles are pushed one by one into the storage track by the tile pusher head until all mahjong tiles are stacked.

[0003] In current mahjong machines, the pusher head of the pusher mechanism is located on the extension line of the length of the tile support plate. After the mahjong tiles are pushed past the tile suction mechanism and stacked up and down, the pusher head pushes the pair of mahjong tiles onto the tile support plate for stacking. For example, Chinese invention patent CN112023390A, published on December 4, 2020, discloses a mahjong machine, including a large shuffling tray located in the center of the machine frame base plate. Four sets of card picking and transporting systems are arranged around the shuffling tray. The card picking and transporting system includes a card feeding device, a flat-push card loading device, and a card pushing device. The flat-push card loading device includes a card receiving plate, a card supporting plate, and a card pushing plate. The card supporting plate is located inside the card receiving plate, and the card pushing plate is located outside the card receiving plate and pushes the card from the outside to the inside. One end of the card receiving plate extending along the length direction is the card inlet. A card receiving block of the card pushing device is set outside the card inlet. The flat-push card loading motor drives the card pushing plate to move horizontally and the card supporting plate to lift and lower the card. The mahjong machine panel has four card loading ports that are respectively inclined relative to the side of the tabletop. The four card supporting plates in the four sets of card picking and transporting systems are respectively matched with the four card loading ports. The method of stacking cards described above has limitations. If there is not enough space on both sides of the card support board along its length, it is impossible to place the card pusher head to load the cards.

[0004] Therefore, it is necessary to propose a mechanism and mahjong machine that can push the tiles and turn them to meet the needs of playing tiles in different directions. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a card-pushing and turning mechanism and a mahjong machine, which aims to solve the technical problem of the large limitation of card-pushing head in the prior art.

[0006] To achieve the above objectives, this utility model proposes a card-pushing and turning mechanism, including a card-pushing head, a card-absorbing mechanism, and a card-supporting plate; it also includes a turning track, one end of which is connected to the outlet of the card-absorbing mechanism, and the other end of which is connected to the card-supporting plate; the card-pushing head pushes the mahjong tiles from the card-absorbing mechanism to turn along the turning track and enter the card-supporting plate.

[0007] Preferably, the turning track is a circular arc track with a turning angle of 15° to 160°.

[0008] Preferably, the card pusher head includes a rotating rod and a card pusher; one end of the rotating rod is rotatably fixed to the frame, and the other end is connected to the card pusher, which moves back and forth along the steering track.

[0009] Preferably, the length direction of the card suction track of the card suction mechanism is parallel to the length direction of the card support plate, and the end of the rotating rod away from the pushing rod is rotatably fixed to the card suction mechanism.

[0010] Preferably, the card-collecting mechanism is further provided with a disc, and the disc is rotatably provided with a rotating shaft; the card-pushing rod is provided with a circular track, and the circular track is provided with a delay arc.

[0011] Preferably, the disk is driven to rotate by a driving mechanism. The outer ring of the disk is provided with a large gear ring, and a first pinion is meshed on the gear ring. A third pinion is concentrically provided on the first pinion ring through a connecting rod. The third pinion meshes with a large gear, and the large gear is driven by a motor.

[0012] Preferably, the angle between the push rod and the rotating rod is 100°~170°, and the end of the push rod that is furthest away is always close to the outlet of the card-collecting mechanism during the movement; when it moves to the farthest end, it can block the mahjong tiles from the outlet of the card-collecting mechanism.

[0013] To achieve the above objectives, this utility model proposes a mahjong machine that uses the aforementioned card-pushing and turning mechanism.

[0014] Compared with the prior art, the beneficial effects of the mahjong machine and tile-pushing steering mechanism provided by this utility model are as follows:

[0015] It can first turn the mahjong tiles out of the card-collecting mechanism before they enter the card-holding plate, which solves the limitation of the traditional card-pushing head that can only push left and right, and has a wider range of applications.

[0016] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0024] In the description of this utility model, it should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.

[0025] In the description of this utility model, it should be noted that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0026] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] This utility model provides a mahjong machine, including a card-pushing and turning mechanism. The mahjong machine is formed by four card-pushing and turning mechanisms connected end to end in a square shape.

[0028] See Figure 1 The card-pushing and turning mechanism of this solution includes a card-pushing head 1, a card-absorbing mechanism 2, and a card-supporting plate 4; it also includes a turning track 3, one end of which is connected to the outlet of the card-absorbing mechanism 2, and the other end is connected to the card-supporting plate 4; the card-pushing head 1 pushes the mahjong tiles out of the card-absorbing mechanism 2 to turn along the turning track 3 and enter the card-supporting plate 4.

[0029] Specifically, because the right side of the tile-holding plate 4 is blocked, the placement of the commonly used tile-pushing head 1 cannot be adopted. In a typical design, the tile-pushing head is placed on the right side of the tile-holding plate, with the tile-absorbing track perpendicular to the plate. After the mahjong tiles enter the stacked tiles from the absorption track, the tile-pushing head pushes them onto the tile-holding plate. However, in this design, the mahjong tiles exiting the tile-absorbing mechanism 2 are not directly facing the tile-holding plate 4, making it impossible to directly push them forward. Therefore, a deflecting track 3 is required, allowing the mahjong tiles to be turned and placed onto the tile-holding plate 4. The specific turning angle can be adjusted based on the position of the incoming mahjong tiles.

[0030] See Figure 1 and Figure 2 The card pusher head 1 includes a rotating rod 11 and a card pusher 12; one end of the rotating rod 11 is rotatably fixed on the frame, and the other end is connected to the card pusher 12, which moves back and forth along the steering track 3.

[0031] Furthermore, see Figure 1 The end of the rotating rod 11 away from the pusher rod 12 can be rotatably fixed to the card suction mechanism 2, further saving space.

[0032] For further details, please refer to [link / reference]. Figure 1 The steering track 3 is a circular arc track with a steering angle of 15° to 160°. The preferred steering angle is 90° to achieve vertical reversal, which is more reasonable for use in a mahjong machine.

[0033] See Figure 1 and Figure 2The length direction of the card-collecting mechanism 2 is parallel to the length direction of the card-supporting plate 4, which can save space better, make the card placement position closer to the center, and make the mahjong table smaller.

[0034] See Figure 1 , Figure 3 and Figure 4 The card-collecting mechanism 2 is also equipped with a disc 6, on which a rotating shaft 61 is rotatably mounted. The card-pushing rod 12 is equipped with a circular track 121, on which a delay arc 122 is mounted.

[0035] Specifically, in the initial process, the rotating shaft 61 is about to enter the delay arc 122. When the card-collecting mechanism 2 draws a mahjong tile into the stacking plate of the pusher head 1, the stacking plate descends, and the card-collecting mechanism 2 transports another mahjong tile to the top of the stacking plate, so that the two mahjong tiles are stacked together. The lifting mechanism of the stacking plate can adopt any mechanism currently used in mahjong, such as the mechanism used in the prior art CN112023390A. Since at this time the rotating shaft 61 rotates counterclockwise along the delay arc 122 (with... Figure 1 (For reference) Rotate, the disc 6 rotates, and the pusher head 1 remains stationary. When the rotating shaft 61 leaves the delay arc 122, the pusher rod 12 begins to rotate with the rotation fixed point of the rotating rod 11 as the center, and the mahjong tiles are turned along the turning track 3 to adjust their direction to enter the tile support plate 4.

[0036] See Figure 1 The angle between the push rod 12 and the rotating rod 11 is 100°~170°. The far end of the push rod 12 is always close to the outlet of the card suction mechanism 2 during the movement; when it moves to the farthest end, it can block the mahjong tiles from the outlet of the card suction mechanism 2.

[0037] Specifically, when rotating to the furthest point, such as Figure 3 As shown, the push rod 12 is in a vertical position at this time, and its lower part blocks the outlet of the card-collecting mechanism 2, preventing the mahjong tiles from sliding out of the outlet. The card-collecting mechanism 2 can adopt existing card-collecting solutions. Existing card-collecting mechanisms transport the mahjong tiles by rotating a belt pulley. The mahjong tiles are magnetic, and a magnetic attraction can be set on the belt pulley. Each rotation of the belt pulley can collect one tile. The conveying channel of the card-collecting mechanism 2 is relatively narrow, just enough to pass through one tile (the narrow edge of the tile).

[0038] See Figure 3 and Figure 4The disc 6 is driven to rotate by a drive mechanism 7. A large gear ring 62 is provided on the outer circumference of the disc 6. A first pinion 71 meshes with the gear ring 62. A third pinion 73 is concentrically arranged on the first pinion 71 via a connecting rod 72. The third pinion 73 meshes with a large gear 74, which is driven by a motor 75. Due to the limited space in the mahjong machine, the above arrangement allows the motor 75 to be placed on the tile pusher 12, resulting in a more rational space allocation.

[0039] The working process of this plan:

[0040] The card-collecting mechanism 2 sucks the mahjong tiles one by one into the conveyor channel. When the first mahjong tile enters the stacking plate, the card-pushing head 1 is in position... Figure 1 Positioned so that the rotating shaft 61 is about to enter the delay arc 122, the stacking plate descends, and the suction mechanism 2 transports another mahjong tile to the top of the stacking plate, causing the two mahjong tiles to stack together. During this process, the motor 75 remains running, and the rotating shaft 61 moves within the delay arc 122.

[0041] When the rotating shaft 61 leaves the delay arc 122, the pusher lever 12 slowly rotates, pushing the mahjong tiles on the stacking plate onto the turning track 3 to achieve a reversal. Before the mahjong tiles leave the stacking plate, they block the exit of the suction mechanism 2, preventing other mahjong tiles from exiting. When the mahjong tiles leave the stacking plate, the pusher lever 12 again blocks the exit of the suction mechanism 2, preventing other mahjong tiles from exiting. The final state of the reversal is as follows: Figure 3 As shown, the pusher lever 12 is in a vertical position.

[0042] Motor 75 continues to rotate, and shaft 61 drives push lever 12 clockwise (towards...). Figure 1 (For reference only) The motor 75 does not need to be reversed, while the shaft 61 can drive the push rod 12 to reverse, thus extending the motor's lifespan.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
