Description

Technical Field

[0001] The utility model belongs to the field of mahjong machines, in particular to a card pushing and loading mechanism of a mahjong machine. Background Art

[0002] Existing mahjong machines basically use a card pusher to push the mahjong tiles onto a lifting plate, and then the lifting plate is raised by a motor to push the mahjong tiles onto the table. The entire process of putting the mahjong tiles on the table requires multiple steps, and each step requires multiple parts to work smoothly before and after, resulting in too many steps and parts and being too complicated. Once a single part is damaged, the mahjong machine will not operate normally, and too many parts further increase the probability of the mahjong machine not operating normally.

The structure of the present invention is ingenious, and it can lift the mahjong cards on all four sides of the mahjong machine to the card-drawing position at one time. The technical solution provided by the invention is to push the mahjong cards onto the lifting plate through a card-pushing head, and then the electric lifting plate is raised by a motor to push the mahjong cards to the tabletop. In combination with its attached drawings, it can be clearly seen that the entire card-loading process requires a certain number of parts, and the entire step is also relatively complicated.

DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figure 1-4 As shown, a card pushing and loading mechanism of a mahjong machine includes a card receiving seat 10 and a card pushing head 11, the card receiving seat 10 is connected to a lifting mechanism 12, the card receiving seat 10 is located on one side of one end of a card storage and conveying channel 13 and the card receiving seat 10 is adjacent to the card storage and conveying channel 13, a transmission bar 14 is provided below the card storage and conveying channel 13, a card pushing head 11 is fixed on the transmission bar 14, the card storage and conveying channel 13 has a card body conveying rail 15 and a groove body 29 extending axially thereof is provided on the card body conveying rail 15, the card pushing head 11 can move axially along the card storage and conveying channel 13 driven by the transmission bar 14, the card pushing head 11 is located above the card storage and conveying channel 13 and one side of the card pushing head 11 extends to above the card receiving seat 10.

[0029] In the present embodiment, the mahjong tiles are transported to the card receiving seat 10, and the card receiving seat 10 is lowered to the entrance of the card storage and conveying channel 13 by the lifting mechanism 12, and then the transmission bar 14 is transmitted by the power source and drives the card pushing head 11 to move axially along the card storage and conveying channel 13. At this time, the card pushing head 11 only moves a distance of about the width of a stack of mahjong tiles, thereby gradually transporting the stacks of mahjong tiles received by the card receiving seat 10 to the card storage and conveying channel 13 in turn until the card storage and conveying channel 13 stores a specified number of mahjong tiles. Finally, the transmission bar 14 is transmitted by the power source and drives the card pushing head 11 to move axially along the card storage and conveying channel 13. At this time, the card pushing head 11 continues to move forward along the axial movement of the card storage and conveying channel 13 until all the mahjong tiles on the card storage and conveying channel 13 are pushed onto the table.

[0030] The existing mahjong machines basically push the mahjong tiles onto the lifting plate through the pusher head 11, and then the lifting plate is raised by the motor to push the mahjong tiles onto the table. The present embodiment omits the lifting action of the lifting plate, which not only saves the lifting plate parts but also saves the motor for lifting the lifting plate. The mahjong tiles are directly pushed onto the table along the card storage and conveying channel 13 by the pusher head 11, so that the structure of the mahjong machine is simplified.

[0031] The transmission bar 14 is connected to the driver and the driver drives the transmission bar 14 through forward and reverse rotation to drive the card pushing head 11 to move back and forth to push the cards, and when the card loading is completed, the driver drives the transmission bar 14 to move along the axis of the card storage and conveying channel 13 to drive the card pushing head 11 to load the cards. The driver is placed in a driver placement frame 16, and the transmission bar 14 is arranged in a circle along the card storage and conveying channel 13. The driver is connected to the transmission bar 14 to drive the transmission bar 14 to operate.

[0032] In this embodiment, when the mahjong tiles are transported to the card storage and conveying channel 13, the driver drives the transmission bar 14 through forward and reverse rotation to drive the card pushing head 11 to move back and forth to push the tiles, thereby gradually pushing the mahjong tiles into the card storage and conveying channel 13. After a specified number of mahjong tiles are pushed into the card storage and conveying channel 13, the driver drives the transmission bar 14 to move along the axis of the card storage and conveying channel 13 to drive the card pushing head 11 to load the tiles.

[0033] The transmission bar 14 is a chain, and the lower part of the card pushing head 11 is fixed on the chain.

[0034] In this embodiment, according to the characteristics of the chain, the card storage and conveying channel 13 can be set in a winding manner, and does not need to be set straight, which saves space and solves the problem of the mahjong card stack turning back and pushing it onto the table.

[0035] A chain link portion 17 is disposed at the lower end of the card pushing head 11 . The chain link portion 17 is connected to a chain, and a card pushing portion 19 is disposed on the chain link portion 17 .

[0036] In this embodiment, the chain 18 is arranged at the lower end of the card pushing head 11. The chain 18 is located below the card storage and conveying channel 13. During the conveying process, it will not interfere with the card storage and conveying channel 13 and the mahjong tiles.

[0037] The chain link portion 17 has guide grooves 20 on both sides, and the transmission bar 14 has guide bars 21 on both sides, which are arranged on the card storage and conveying channel 13 and extend along the axis of the conveying channel 13. The guide bars 21 are slidably connected to the guide grooves 20 respectively.

[0038] In this embodiment, the guide groove 20 and the guide bar 21 guide the operation of the transmission bar 14 and limit the transmission bar 14 from shaking left and right, and the "convex" structure formed by the guide groove 20 and the guide bar 21 can limit the transmission bar 14 from shaking up and down, thereby improving stability.

[0039] The card pushing portion 19 has a card pushing surface 22, which is arranged to be inclined upward from bottom to top, and has a protruding lower card pushing surface 31 and an upper card pushing surface 32 at the lower and middle parts of the card pushing surface 22, respectively. The upper and lower spacing between the lower card pushing surface 31 and the upper card pushing surface 32 is not less than the height of a mahjong tile.

[0040] In this embodiment, the inclined surface of the card pushing surface 22 has a guiding function. In the process of pushing the mahjong tiles, the mahjong tiles below are gradually moved to the position corresponding to the lower card pushing surface 31. As the card pushing part 19 continues to push, the mahjong tiles below and the mahjong tiles above are respectively against the lower card pushing surface 31 and the upper card pushing surface 32, so that a stack of mahjong tiles can be neatly pushed into the card storage and conveying channel 13.

[0041] The card holder 10 comprises a base 23 , on which a receiving groove 24 is provided, in which a magnet is provided, and a card pad is provided on the top of the base 23 .

[0042] In this embodiment, the magnet can absorb the mahjong tiles to prevent them from falling, and can also prevent the mahjong tiles from falling during the swing of the swing rod 13. The tile pad can prevent the magnet from absorbing the mahjong tiles with too much force, resulting in the tiles being pushed to the storage channel unsmoothly.

[0043] A card guide surface 25 located in the card storage and conveying channel 13 is provided in front of the card receiving seat 10, and the end of the card guide surface 25 close to the card receiving seat 10 is away from the card conveying rail 15, and the card guide surface 25 gradually approaches the card conveying rail 15 from this end until it extends parallel to the card conveying rail 15.

[0044] In this embodiment, in order to smoothly transfer the mahjong stack from the card holder 10 to the card storage and conveying channel 13, the card body guide surface 25 has a guiding function, and the mahjong tiles will move along the card body guide surface 25 to the card storage and conveying channel 13.

[0045] The lifting mechanism 12 includes a rocker arm 26, and the card receiving seat 10 is arranged at one end of the rocker arm 26. The rocker arm 26 and the rocker arm seat 27 are swingably connected through a swing connection structure. A slow-down control structure is provided between the rocker arm 26 and the rocker arm seat 27. The top of the rocker arm seat 27 has a guiding slope 28 adjacent to the pushing direction of the card pushing head 11, and when the card receiving seat 10 receives two mahjong tiles, the lower side of the guiding slope 28 is arranged adjacent to the front end of the card receiving seat 10.

[0046] In this embodiment, the slow descent control structure enables the card holder 10 to move slowly downward after receiving the mahjong tiles, thereby preventing the mahjong tiles from falling due to excessive speed.

[0047] The height of the outlet of the card holder 10 is slightly lower than the entrance of the card storage and conveying channel 13. The guide slope 28 can smoothly transfer the mahjong pile to the card storage and conveying channel 13 to prevent the bumps caused by the height difference between the upper and lower parts from causing the mahjong pile to be uneven.

[0048] The slow-descent control structure includes a counterweight body 30 disposed at the other end of the swing rod 26. The weight and quantity of the counterweight body 30 are configured according to the weight of the mahjong tiles.

[0049] In this embodiment, when the card holder 10 receives a mahjong tile, the card holder 10 begins to descend under the gravity of the mahjong tile, and when the card holder 10 receives the second mahjong tile, the card holder 10 at least descends by the height of one mahjong tile, so that the card feeding device can transport the second mahjong tile to the first mahjong tile and stack them into a pile. Under the weight of the two mahjong tiles, the swing rod 26 further swings to make the card holder 10 further descend and descend to the height connected with the card storage channel 11. The counterweight 30 is used to counteract the weight of the mahjong tiles themselves to achieve the swing rod 26 to drive the card holder 10 to slowly rise and fall.

[0050] The weight and quantity of the counterweight body 30 can be adjusted and configured according to the weight of the mahjong tiles. The device can adapt to mahjong tiles of different sizes and has a certain adaptability.

[0051] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0052] Although the present invention uses more terms such as the card delivery and receiving base 10, the card pushing head 11, the lifting mechanism 12, the card storage and conveying channel 13, the transmission bar 14, the card body conveying rail 15, the slot body 29, the driver, the chain link part 17, the card pushing part 19, the guide slot 20, the guide bar 21, the card pushing surface 22, the base 23, the accommodating groove 24, the card body guiding surface 25, the swing rod 26, the swing rod seat 27, the guiding inclined surface 28, the counterweight body 30, the card pushing down surface 31, and the card pushing up surface 32, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
