Description

Technical Field

[0001] This utility model belongs to the technical field of mahjong machines, and in particular relates to a mahjong machine and its flat-push tile-loading device. Background Technology

[0002] An automatic mahjong machine is a mahjong game auxiliary device that integrates mechanical transmission, electronic control, and magnetic sorting technology. Its core function is to replace manual operation in completing the processes of shuffling, arranging, and stacking mahjong tiles. The automatic mahjong machine was designed to improve the efficiency and convenience of the mahjong game, avoiding the tedious operations of traditional manual shuffling and stacking.

[0003] Referring to Chinese Patent Publication No. CN205832565U, entitled "A Lifting Mechanism for a Mahjong Machine," the lifting mechanism of this document includes a bracket, a card-pushing device, and a card-lifting device. The card-lifting device includes a card-supporting plate, a card-lifting crank, a card-lifting gear, and a card-lifting motor that drives the card-lifting gear to rotate. The card-lifting crank is hinged to the bracket. The rotation of the card-lifting gear drives the card-lifting crank to swing back and forth around the hinge point to drive the card-supporting plate to rise and fall. This application hinges the lifting crank to the support of the pushing mechanism, and the lifting gear drives the lifting crank to swing back and forth around the hinge point. This allows the lifting gear to be placed as close as possible to the bottom of the support while meeting the lifting height requirements of the card-holding plate, thereby reducing the thickness of the entire pushing mechanism and the longitudinal space occupied by the pushing mechanism in the mahjong machine. The mahjong machine can be designed to be thinner and lighter. However, the linkage structure is prone to damage, has low reliability, the linkage movement is prone to stagnation, the two card-holding rocker arms are prone to uneven force, the stability and synchronization of the action are poor, and the installation, maintenance and debugging are more difficult.

[0004] Chinese patent publication CN120132323A, entitled "Mahjong Machine and its Flat-Push Tiling Device," addresses the shortcomings of the aforementioned applications. This application's tile-carrying plate transmission mechanism includes two tile-carrying curved cams, two tile-carrying rocker arms, two tile-carrying rocker arm shafts, two tile-carrying rotating gears, and two first gears. The first gears are incomplete gears, with toothed and toothless portions. The first gears engage with the tile-carrying rotating gears for transmission: when the toothed portion of the first gear meshes with the tile-carrying rotating gear, the first gear drives the tile-carrying rotating gear to rotate; when the toothless portion of the first gear engages with the tile-carrying rotating gear, the tile-carrying rotating gear does not rotate. The two first gears are driven synchronously by a flat-push tile-carrying motor. This solution employs a full gear transmission mechanism, enhancing torque transmission and load-bearing capacity, and improving the stability and reliability of the tile-carrying plate's lifting and lowering motion. However, the mechanism has a complex structure and high manufacturing cost. The meshing impact when the first gear and the upper transmission gear begin to mesh is large, resulting in loud noise and easy damage to components. Frequent maintenance is required to ensure the meshing accuracy of the first gear and the upper transmission gear. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a mahjong machine and its flat-push card-adding device. By setting the first to fourth actuating parts, the meshing impact when the gears start to mesh can be reduced, the meshing accuracy can be improved, the noise can be reduced, and the device has a simple structure and low cost.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tile-loading device for a mahjong machine includes: a tile-loading base, a tile-supporting plate, a tile-holding plate, and a tile-pushing plate. The tile-supporting plate is located inside the tile-holding plate and can move up and down, while the tile-pushing plate is located outside the tile-holding plate and pushes tiles from the outside in. The device is characterized by further including a tile-supporting plate lifting mechanism for driving the tile-supporting plate to move up and down. The tile-supporting plate lifting mechanism includes:

[0008] The first license plate holder and the second license plate holder are respectively installed on the left and right sides of the bottom of the license plate support plate. The first license plate holder is provided with a first guide groove and the second license plate holder is provided with a second guide groove.

[0009] The first and second card-loading rocker arms have their top ends slidably connected to the first guide groove and their top ends slidably connected to the second guide groove. The bottom ends of the first and second card-loading rocker arms are either fixedly connected or integrally formed with a rocker arm shaft.

[0010] The first and second plate-mounting gears are sector gears. The gear shafts of the first and second plate-mounting gears are fixedly connected to the rocker arm shaft or integrally formed and rotatably mounted on the plate-mounting seat.

[0011] The first transmission gear and the second transmission gear are rotatably mounted on the upper plate holder and can rotate synchronously. When the first transmission gear meshes with the first upper plate holder, the first transmission gear drives the first upper plate holder to rotate, thereby raising and lowering the first upper plate holder. At the same time, the second transmission gear meshes with the second upper plate holder, driving the second upper plate holder to rotate, thereby raising and lowering the second upper plate holder. When the plate holder is lowered to the low position, the first transmission gear disengages from the first upper plate holder, and at the same time, the second transmission gear disengages from the second upper plate holder.

[0012] A first actuating element is provided on the first plate-mounting gear, a second actuating element is provided on the first transmission gear, a third actuating element is provided on the second plate-mounting gear, and a fourth actuating element is provided on the second transmission gear. The second actuating element actuates the first actuating element, causing the first plate-mounting gear to mesh with the first transmission gear. At the same time, the third actuating element actuates the fourth actuating element, causing the second plate-mounting gear to mesh with the second transmission gear, thereby driving the plate-mounting plate to rise.

[0013] In some embodiments, the first actuating member, the second actuating member, the third actuating member, and the fourth actuating member are respectively provided with transition surfaces. When the second actuating member actuates the first actuating member, the transition surface of the second actuating member cooperates with the transition surface of the first actuating member to enable them to engage smoothly. At the same time, the transition surface of the third actuating member cooperates with the transition surface of the fourth actuating member to enable them to engage smoothly.

[0014] In some embodiments, the first toggle member, the second toggle member, the third toggle member, and the fourth toggle member are rod-shaped toggle members.

[0015] In some embodiments, the system further includes a third gear and a fourth gear, wherein the third gear meshes with a first transmission gear, the fourth gear meshes with a second transmission gear, and the third gear or the fourth gear is driven to rotate by a motor.

[0016] In some embodiments, the tip circle diameters of the third and fourth gears are larger than the tip circle diameters of the other gears.

[0017] In some embodiments, a card-pushing plate pushing mechanism is also included. The card-pushing plate pushing mechanism includes a cam and a pushing swing rod. The pushing swing rod is hinged to the upper card holder and is connected to the cam. The cam is coaxially fixed and rotates synchronously with a third gear or a fourth gear, driving the pushing swing rod to swing back and forth, thereby driving the card-pushing plate to move back and forth to push the card.

[0018] In some embodiments, the card-pushing mechanism further includes a support block, a guide rod, and an abutment plate. The card-pushing plate is fixedly installed on the support block, the support block is fitted onto the guide rod, one end of the guide rod is fixed to the upper card holder, and the other end is provided with an abutment plate for abutting against the support block. The support block is fitted onto the guide rod, the upper end of the horizontal pushing swing rod is slidably connected to the support block, and the lower end of the horizontal pushing swing rod is hinged to the upper card holder.

[0019] In some embodiments, the lower end of the horizontal pusher arm is hinged to the upper plate seat via a connecting rod. One end of the rotating arm is fixedly connected to the connecting rod, and the other end of the rotating arm is connected to a roller. The roller cooperates with a cam and rolls on the curve of the cam to drive the horizontal pusher arm to swing back and forth. A reset component is installed on the connecting rod.

[0020] In some embodiments, the cam curve of the cam includes a non-driving segment and a driving segment: when the cam is working in the non-driving segment, it does not drive the push plate to move. At this time, the first transmission gear meshes with the first card-up gear, and the second transmission gear meshes with the second card-up gear. When the push cam is working in the driving segment, it drives the push plate to push the card or reset. At this time, the first transmission gear disengages from the first card-up gear, and the second transmission gear disengages from the second card-up gear.

[0021] This utility model also discloses a mahjong machine, including the aforementioned mahjong machine's flat-push tile-loading device.

[0022] This utility model has the following beneficial effects:

[0023] The automatic mahjong machine of this invention employs a gear transmission for its card-carrying plate lifting mechanism. The constant speed ratio between the gears ensures smoother and more continuous motion transmission, enhances torque transmission and load-bearing capacity, and provides high reliability, ease of maintenance, and longer maintenance intervals. The first to fourth accessory rods improve meshing accuracy, significantly reducing meshing impact during the initial engagement of the first card-carrying gear with the first transmission gear and the second card-carrying gear with the second transmission gear. This extends the mechanism's lifespan, reduces noise, and results in a simple and low-cost device. Attached Figure Description

[0062] refer to Figure 4 and Figure 12 When the tile-holding plate 2 completes one tile-holding cycle, it is in a raised state, and the tile-receiving plate 3 receives the mahjong tiles. During the horizontal tile-holding cycle, the motor drives the fourth gear to rotate counterclockwise, the fourth gear 92 drives the second transmission gear 82 to rotate clockwise, the second transmission gear 82 drives the second tile-holding gear 72 and the second tile-holding rocker arm 62 to rotate counterclockwise, the fourth gear 92 drives the third gear 91 to rotate clockwise, the third gear 91 drives the first transmission gear 81 to rotate counterclockwise, the first transmission gear 81 drives the first tile-holding gear 71 and the first tile-holding rocker arm 61 to rotate clockwise, and the tile-holding plate 2 descends; at the same time, the cam 120 is driven to rotate by the motor 100, the swing end roller 125 of the rotating arm 124 moves on the non-drive section 1201 of the cam 120, and the tile-pushing plate 4 remains stationary.

[0063] refer to Figure 13 The card-holding plate 2 moves from the highest point to the lowest point. At this time, the second transmission gear 82 and the second card-loading gear 72, and the first transmission gear 81 and the first card-loading gear 71 have just disengaged, and the card-holding plate 2 stops moving. The swing end roller 125 of the rotating arm 124 moves to the junction of the non-drive section 1201 and the drive section 1202 of the cam 120, and the card-pushing plate is ready to start pushing the card.

First card-feeding rocker arm 61 and first card-feeding gear 71, second card-feeding rocker arm 62 and second card-feeding gear 72 do not rotate, and card-supporting plate 2 remains stationary at the lowest point to receive cards. At this time, cam 120 continues to rotate driven by motor 100, and the swing end roller 125 of rotating arm 124 moves on the drive section 1202 of cam 120, moving from the lowest point to the highest point, thereby driving push plate 4 to push the mahjong tiles on card-bearing plate 3 onto card-supporting plate 2.

[0065] refer to Figure 15 When the cam 120 rotates, the swing end roller 125 of the rotating arm 124 moves on the drive section 1202 of the cam 120, returning from the highest point to the lowest point. The push plate 4 is reset. At this time, the motor 100 drives the fourth gear 92 to rotate clockwise. The fourth actuating element 821 actuates the third actuating element 721. The second transmission gear 82 meshes with the second plate-raising gear 72. The second actuating element 811 actuates the first actuating element 711.

[0066] refer to Figure 16 Motor 100 drives the fourth gear 92 to continue rotating clockwise, and the first card-laying bracket 51 and the second card-laying bracket 52 rise to their highest point, thereby raising the mahjong tiles on them onto the table. At the same time, cam 120 is driven by motor 100 to continue rotating, and the roller at the swing end of the horizontal push rocker arm moves on the non-drive section of the horizontal push cam, away from the junction of the non-drive section and the drive section, while the card-pushing plate remains stationary.
