Description

Technical Field

[0001] The utility model relates to the field of mahjong machines, in particular to a card stacking and pushing device and a rotor-type mahjong machine. Background Art

[0002] The stacking and pushing device is an indispensable device in the mahjong machine. Its main function is to stack two or three mahjong tiles together and push them onto the card lifting mechanism. At present, the stacking and pushing devices of the rotary-wing mahjong machines basically adopt the stacking and pushing devices of the four-mouth machines, which are generally the same in principle. For example, the announcement number is CN206473781U, which announces a stacking and pushing system, including a stacking and pushing box, a pushing head, a stacking motor, a stacking plate and a first sensor for detecting mahjong tiles on the stacking plate. The stacking and pushing box is internally installed with a horizontal part for driving the pushing head to move horizontally, a vertical part for pushing the stacking plate up and down and a stacking wheel. The vertical part includes a stacking and pushing lever, one end of the stacking and pushing lever is hingedly connected to the stacking and pushing box, and the other end is hingedly connected to the stacking plate. The axial end face of the stacking wheel is provided with a stacking wheel abutting on the stacking and pushing lever. An arc-shaped groove is arranged at the position where the push lever abuts against the stacking wheel; the stacking motor drives the stacking wheel to rotate; the horizontal member includes a slide rail fixed on the stacking box and a stacking slider slidably connected to the slide rail, the stacking slider is provided with a vertically arranged stacking slide groove, the stacking slide groove is a multi-section tangent arc, an eccentric stacking shaft is arranged on the axial section of the stacking wheel, and the stacking shaft and the stacking slide groove are slidably matched; a first magnetic sensor is arranged in the stacking box, and three magnetic heads for detecting positioning are arranged around the circumference of the stacking wheel, and the magnetic heads are respectively arranged at the highest point and the lowest point of the stacking support plate stroke, and the position corresponding to the first magnetic sensor on the stacking wheel when the push head leaves the stacking support plate.

[0003] When the card stacking and pushing device of the above structure is assembled on the card storage rack, it will bulge outwards, for example, Figure 1 The motor on this structure is installed horizontally and drives the card stacking wheel. The motor can only be used for stacking and pushing cards and cannot be shared with other decorations.

[0004] In other prior arts, a common motor is also used to drive the card stacking and pushing device. However, the driving gear on the motor of the prior art cannot directly drive the gear on the card stacking wheel. Since the gear on the card stacking wheel is arranged at the bottom, the card stacking wheel rotates to pull the card pushing part below to move, so two other gears are needed to transmit power. This structure requires multiple gears to transmit, has poor stability, and is also costly. Utility Model Content

[0041] The following is combined with Figure 1-5 The utility model is further described in detail with examples.

[0042] Example 1

[0043] The card stacking and pushing device comprises a card storage rack 10, a motor 11 and a stacking and pushing mechanism. The motor 11 is fastened to the card storage rack 10 by screws and connected to the stacking and pushing mechanism. The motor 11 is used to drive the stacking and pushing mechanism to achieve card stacking and card pushing actions. The stacking mechanism first stacks the mahjong cards together and then pushes them into the card storage slots 103 corresponding to the card storage rack 10. A driving gear 12 for driving the stacking and pushing mechanism is installed on the output shaft of the motor 11;

[0044] The stacking mechanism includes a stacking wheel 13, a driven gear 14, a card receiving seat 15 and a card pushing rod 16. The driven gear 14 is fixed on the stacking wheel 13 and rotates synchronously with it. The central axis of the driven gear 14 is colinear with the central axis of the stacking wheel 13. In this embodiment, the driven gear 14 is integrally formed on the top of the stacking wheel 13. In other embodiments, the driven gear 14 can also be fixed on the stacking wheel 13 by screw fastening. The driven gear 14 is meshed and connected with the driving gear 12, and the motor 11 transmits power to the stacking wheel 13 and drives it to rotate;

[0045] The stacking wheel 13 is connected to the card receiving seat 15. The stacking wheel 13 rotates and drives the card receiving seat 15 to rise and fall. The motor 11 drives the stacking wheel 13 to rotate, thereby driving the card receiving seat 15 to rise and fall, thereby realizing the stacking action.

[0046] A rolling body 17 deviating from the axis is installed on the upper end surface of the driven gear 14, and a guide card pushing hole 171 for the rolling body 17 to pass through is provided on the card pushing rod 16. The rolling body 17 moves along the guide card pushing hole 171 and drives the card pushing rod 16 to swing back and forth, thereby realizing a reciprocating card pushing action.

[0047] The driving gear 12 of the motor 11 on the card stacking and pushing device directly drives the driven gear 14 on the card stacking wheel 13, and there is no other gear as a transition gear between the driving gear 12 and the driven gear 14, so that fewer parts are required in the power transmission process, the stability of the power transmission is high, and the failure rate is low. At the same time, the rolling body 17 on the card stacking wheel 13 can directly drive the card pushing rod 16 to swing, so the transmission efficiency is high and the structure is exquisite.

[0048] A mounting groove 101 extending vertically downward is provided on the card storage rack 10, and the card stacking wheel 13 is installed in the mounting groove 101. A pin is fixed at the bottom center of the mounting groove 101, and the card stacking wheel 13 is sleeved on the pin. A guide lifting hole 102 arranged vertically and penetrating to the inside is provided on the side of the mounting groove 101. The guide lifting hole 102 is a long strip hole. A first track 131 is provided on the circumferential side of the card stacking wheel 13. A roller 18 is installed on the inner end of the card receiving seat 15. The roller 18 extends into the first track 131 through the guide lifting hole 102. When the roller 18 moves relatively along the first track 131, the card receiving seat 15 is lifted up and down.

[0049] A support plate 19 is installed at the outer bottom of the mounting groove 101, and at least one guide rod 20 is installed at the end of the support plate 19. In this embodiment, there are two guide rods 20. The card holder 15 is sleeved on the guide rods 20 and rises and falls along the guide rods. The card holder 15 has good stability when it is raised and lowered along the guide rods 20.

[0050] At least one top column 21 is installed on the support plate 19. In this embodiment, there are two top columns 21 evenly distributed at the lower end of the stacking wheel 13. The top column 21 is installed on the support plate 19 through a spring, and the top column 21 is pressed against the bottom surface of the stacking wheel 13 through the spring.

[0051] One end of the card pushing rod 16 is hinged on the card storage rack 10 through a pin shaft, and the other end is installed with a card pushing block 22. The card pushing block 22 is provided with a notch 221 facing upward, and other components can pass through this notch 221 when moving to avoid interference between components.

[0052] The card storage rack 10 is provided with an arc-shaped card storage slot 103, and the card receiving seat 15 is arranged at the end of the card storage slot 103. The card storage slot 103 surrounds the card stacking wheel 13 and the motor 11. The motor 11 and the card stacking wheel 13 do not protrude from the card storage rack 10 in the radial direction, thereby ensuring the compactness of the card stacking and pushing device structure.

[0053] Example 2

[0054] Embodiment 2 has basically the same features as Embodiment 1, except that a grooved second track 132 and a third track 133 are provided on the bottom surface of the stacking wheel 13, the second track 132 and the third track 133 are on the same circumference, the groove bottom at the head end of the second track 132 is inclined upward and extends toward the tail end of the third track 133, and the groove bottom at the head end of the third track 133 is inclined upward and extends toward the tail end of the second track 132. When the stacking wheel 13 rotates, the end of the top column 21 moves relative to the second track 132 and the third track 133, and the cooperation between the top column 21 and the second track 132 and the third track 133 can prevent the stacking and pushing device from moving when the motor 11 is reversed.
