Description

Technical Field

[0001] The utility model belongs to the technical field of mahjong machines, and in particular relates to a mahjong machine with arc-shaped card loading and a card pushing mechanism thereof. Background Art

[0002] In the mahjong machine, the card pushing mechanism can push the card piles on the card stacking seat forward to the card storage track one by one according to the program.

[0003] In existing mahjong machines, the card pushing mechanism has the following two main working modes:

[0004] 1. Linear reciprocating type: In traditional card pushing mechanisms (such as CN201949628U, CN205084375U, CN206577364U, CN107281748B, CN213159332U, etc.), the working path of the card pushing head is linear reciprocating, that is, when the stacking seat completes the stacking of a pile of cards, the card pushing head first pushes the pile of cards forward into the card storage track. During this process, the card pushing head occupies the position of the stacking seat and blocks the card outlet of the conveying channel; then, the card pushing head returns to the starting point of pushing cards, giving up the position of the stacking seat, and the mahjong cards in the conveying channel can come to the stacking seat, be stacked into a pile of cards, and wait for the next push. This card pushing method is inefficient and time-consuming.

[0005] Second, circumferential reciprocating type: as the Chinese invention patent with the announcement number CN112807668B discloses a mahjong machine push card machine head, the push card machine head comprises a machine head box, the machine head box is provided with a push card head carrier connected end to end, the push card head carrier is driven by a push card motor and rotates circumferentially, in the process of the push card head carrier rotating circumferentially, the push card head arranged on the push card head carrier will then reciprocate through the push card position (i.e. the position of the stacking card seat), and implement the push card action. In this push card machine head, the working path of the push card head is circumferentially reciprocating, the push card action and the stacking card action are carried out simultaneously, do not affect each other, and the efficiency of loading cards is significantly improved. However, in order not to affect the push card head to rotate after pushing the card pile into the storage card track, not only the side wall of the storage card track should be provided with a avoidance port that is compatible with the push card head length, and the area swept during the rotation of the push card head cannot be used for storage cards, which just needs to extend the storage card track on the basis of the original storage card space, resulting in the volume of the mahjong machine becoming larger.

[0006] Currently, there is no card pushing mechanism that drives the card pushing work through a lever structure. Utility Model Content

[0007] The invention aims to provide a mahjong machine with a novel arc-shaped card loading mechanism and a card pushing mechanism thereof.

[0008] In order to achieve the above-mentioned invention object, the technical solution of the utility model is as follows:

[0009] A mahjong machine card pushing mechanism, the card pushing mechanism comprising:

[0010] A card pushing rod, the rear end of which is movably connected to a hinge point, a card pushing groove is formed in the middle of the card pushing rod, and the head end of the card pushing rod is used for pushing cards;

[0011] A card pushing plate, wherein a card pushing bearing is disposed on the top end surface of the card pushing plate, and the card pushing bearing extends into the card pushing slot to drive the card pushing rod to swing back and forth around the hinge point;

[0012] A driving assembly is used to drive the card pushing plate to rotate.

[0013] In the utility model, the card pushing rod is horizontally placed on the card pushing plate (that is, the length extension direction of the card pushing rod is perpendicular to the axis of the card pushing plate), the card pushing bearing on the card pushing plate extends into the card pushing slot, and the tail end of the card pushing rod is movably connected to the card storage bracket through a hinge point; when the card pushing plate rotates, the card pushing bearing will rotate with the center of the card pushing plate as the central axis, and because the card pushing bearing is in the card pushing slot, the rotation of the card pushing bearing will drive the card pushing rod to swing back and forth, and then the head of the card pushing rod implements the card pushing action; a card pushing mechanism with a novel structure is provided for the mahjong machine.

[0014] In the utility model, since the tail end of the card pushing rod is fixed by the hinge point, when force is applied to the middle part thereof, the card pushing bearing can give the head end of the card pushing rod a larger swing amplitude with a smaller rotation radius, which is very labor-saving.

[0015] In principle, the card pushing bearing can be located at any position on the top end surface of the card pushing plate, as long as it is not coaxial with the card pushing plate, its function can be realized. However, as a preference, in the above-mentioned card pushing mechanism, the card pushing bearing is located at the outer edge of the top end surface of the card pushing plate. The farther the card pushing bearing is from the center of the card pushing plate, the greater the swing amplitude can be provided to the card pushing rod head; conversely, under the preset swing amplitude, a card pushing plate with a smaller radius can also be used to reduce the volume of the card pushing mechanism.

[0016] The utility model has no special requirements on the shape of the card pushing slot, as long as the card pushing bearing can roll or slide smoothly in the card pushing slot without getting stuck. Preferably, the card pushing slot can be in a simple strip or arc shape.

[0017] Preferably, in the above-mentioned card pushing mechanism, the driving assembly comprises a circumferential driver, and the card pushing plate is fixedly connected to the output shaft of the circumferential driver.

[0018] Preferably, the card pushing mechanism of the utility model further comprises a card receiving assembly, and the driving assembly is also used to drive the card receiving assembly to stack the card piles. In this way, both the card stacking and card pushing actions are driven by the driving assembly, which reduces the power cost by half and doubles the efficiency.

[0019] As a further preferred embodiment, in the above-mentioned card pushing mechanism, the card receiving assembly comprises:

[0020] A card receiving cam, which is fixed on the output shaft of the driving assembly, and a card receiving curved groove is concavely provided on the outer peripheral wall of the card receiving cam;

[0021] A card-bearing platform, which is provided with a card-bearing bearing that rolls or slides with the card-bearing curved groove;

[0022] The card pushing rod is used to push the card pile on the card receiving platform.

[0023] The card receiving table is lifted and lowered on the mahjong machine. When the card receiving cam rotates, the card receiving bearing will roll to different positions of the card receiving curve groove, thereby bringing the card receiving table to different heights and finally completing the card stacking action.

[0024] In the card pushing mechanism of the utility model, the card receiving curved groove comprises a horizontal section, a descending curved section and an ascending curved section which are arranged in sequence and connected end to end, the card receiving platform has a first working position which is guided by the horizontal section and remains stationary so that the card pushing rod can push the card and then receive the first mahjong tile, a second working position which is guided by the descending curved section and descends to receive the remaining mahjong tiles, and a third working position which is guided by the ascending curved section and rises to return to the initial position.

[0025] Correspondingly, the card pushing rod has a first working position for pushing cards as the card receiving platform remains stationary, a second working position for returning to the card withdrawing starting point as the card receiving platform descends or as the card receiving platform receives the first mahjong tile and descends, and a third working position for retreating as the card receiving platform rises and returning to the card pushing starting point again.

[0026] That is, in a card stacking process, the initial position and the end position of the card receiving platform are both at the highest point in its lifting stroke, which is exactly at the card outlet of the conveying channel. When the card receiving platform completes the stacking of a pile of cards, the card receiving bearing is in the horizontal section of the card receiving curved groove, and the card pushing rod is at the starting point of pushing cards. As the card receiving cam and the card pushing plate rotate, the card receiving bearing rolls in the horizontal section, so the card receiving platform maintains a constant height and is in a stationary state, but the card pushing rod is driven by the card pushing bearing to swing, pushing the pile of cards forward into the card storage track; after the card pushing rod passes over the card receiving platform, the card receiving bearing is still in the horizontal section, the card receiving platform remains stationary and receives the first mahjong tile; however, after the card receiving platform receives the first mahjong tile, the card receiving bearing enters the downward curved section, driving the card receiving platform to descend, so although the card pushing rod is driven by the card pushing bearing to swing in the opposite direction at this time, It will still not interfere with the card receiving platform and the first mahjong tile on it; and, during the return process, the head end of the card pushing rod will block the card outlet of the conveying channel, so the second mahjong tile will not fall; when the card receiving platform drops to the lowest point, the card pushing rod also returns to its card pushing starting point; as the card receiving bearing enters the upward curve section, the card receiving platform also rises accordingly, and receives the second mahjong tile during the rising process; at the same time, the card pushing rod is driven by the card pushing bearing to swing backward for a certain amplitude and then swing toward the card pushing starting point, so as not to affect the rise of the card receiving platform carrying two mahjong tiles; when the card receiving platform returns to the highest point, the card pushing rod also swings to the card pushing starting point, pushing the card pile forward into the card storage track.

[0027] It can be seen that in the present invention, the card stacking action of the card receiving table and the card pushing action of the card pushing rod do not affect each other. Although the card pushing rod will block the card outlet of the conveying channel in the process of returning to the card pushing starting point, the card receiving table does not need to wait and still works according to the predetermined procedure.

[0028] In the card pushing mechanism of the utility model, the card receiving cam is the card pushing plate;

[0029] Alternatively, the card receiving cam is located below the card pushing plate and the two are fixedly connected or integrally formed. A more preferred solution is not to separately set up a card pushing plate, but to directly use the card receiving cam as the card pushing plate, and to set the card pushing bearing on the top end face of the card receiving cam.

[0030] The utility model also provides a mahjong machine with arc-shaped card loading, which includes a card storage bracket, wherein an arc-shaped card storage track is formed in the card storage bracket, and the card pushing mechanism is arranged at the card inlet of the card storage track;

[0031] The card storage bracket is integrally formed with a groove for installing a card pushing mechanism.

[0032] In the utility model, the card pushing rod implements the card pushing action in a swinging state, so the card pushing path is arc-shaped, which can perfectly fit the mahjong machine with arc-shaped card loading.

[0033] In addition, in the utility model, a groove for installing a card pushing mechanism is integrally formed on the card storage bracket, so the card pushing mechanism does not need to be provided with a head box separately. The card pushing mechanism can be arranged in the groove as a whole, or only the card pushing rod, the card receiving cam, and the card receiving platform can be arranged in the groove, and the driving component can be arranged at the bottom of the card storage bracket.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0035] (1) In the utility model, the card pushing rod is horizontally placed on the card pushing plate (i.e., the length extension direction of the card pushing rod is perpendicular to the axis of the card pushing plate), and the card pushing bearing on the card pushing plate extends into the card pushing slot, and the tail end of the card pushing rod is movably connected to the card storage bracket through a hinge point; when the card pushing plate rotates, the card pushing bearing will rotate with the center of the card pushing plate as the central axis, and because the card pushing bearing is in the card pushing slot, the rotation of the card pushing bearing will drive the card pushing rod to swing back and forth, and then the head of the card pushing rod will implement the card pushing action; a novel card pushing mechanism is provided for the mahjong machine.

[0036] (2) In the utility model, since the tail end of the card pushing rod is fixed by the hinge point, when force is applied to the middle part, the card pushing bearing can give the head end of the card pushing rod a larger swing amplitude with a smaller rotation radius, which is very labor-saving; at the same time, since the card pushing path of the card pushing rod is arc-shaped, it can perfectly dock with the arc-shaped card storage track and be used in an arc-shaped card loading mahjong machine.

[0037] (3) In the utility model, the card pushing bearing is located at the outer edge of the top end surface of the card pushing plate; the farther the card pushing bearing is from the center of the card pushing plate, the greater the swing amplitude it can provide to the head of the card pushing rod; conversely, under the preset swing amplitude, a card pushing plate with a smaller radius can also be used to reduce the volume of the card pushing mechanism.

[0038] (4) In the utility model, the driving assembly is not only used to drive the card pushing rod to swing to push the cards, but also used to drive the card holding assembly to work to stack the card piles, thereby halving the power cost and doubling the efficiency.

[0039] (5) In the present invention, the card stacking action of the card receiving table and the card pushing action of the card pushing rod do not affect each other. Although the card pushing rod will block the card outlet of the conveying channel in the process of returning to the card pushing starting point, the card receiving table does not need to wait and still works according to the predetermined procedure, so the card loading efficiency is high.

[0040] (6) In the utility model, a card receiving cam for driving the card receiving platform to rise and fall is fixedly arranged on the output shaft of the driving component, so that the card receiving cam can directly play the function of pushing the card plate, and the card pushing bearing can be directly arranged on the top of the card receiving cam, thereby simplifying the structure of the card pushing mechanism.

[0041] (7) In the present invention, a groove for installing a card pushing mechanism is integrally formed on the card storage bracket, so the card pushing mechanism does not need to be provided with a head box separately, which simplifies the structure and the assembly steps.

[0055] The specific scheme of the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0056] Example 1

[0057] like Figure 1 As shown, the present embodiment is a mahjong machine card pushing mechanism, comprising a motor 1, a card pushing plate 2 is fixedly mounted on the output shaft of the motor 1, and a card pushing bearing 3 is rotatably mounted on the top end surface of the card pushing plate 2. Figure 1 It can be seen that the card pushing plate 2 is at the end of the output shaft of the motor 1, but the output shaft of the motor 1 will not pass through the card pushing plate 2, ensuring that only the card pushing bearing 3 is protruding on the top end surface of the card pushing plate 2.

[0058] Depend on Figure 1 It can be seen that a card pushing rod 4 is horizontally placed above the card pushing plate 2, and a card pushing groove 41 in a strip shape (or an arc shape) is provided in the middle of the card pushing rod 4. When the card pushing bearing 3 extends into the card pushing groove 41, it can roll along the card pushing groove 41. The tail end 42 of the card pushing rod 4 is movably connected to the hinge point, and the movably connected method can be as follows: Figure 1 As shown in the pin connection, when the card pushing mechanism is used in a mahjong machine, the bottom end of the latch 43 is inserted into the card storage bracket 5; Figure 6 and Figure 7 As shown, in addition to the connection hole 51 for inserting the latch 43, the card storage bracket 5 may also be provided with a sink 52 adapted to the tail end 42 of the card push rod 4 at the opening of the connection hole 51, which can stabilize the hinged relationship between the card push rod and the card storage bracket 5, and also help limit the swing amplitude of the card push rod 4.

[0059] The head end of the card pushing rod 4 is provided with a card pushing head 44 for pushing the card pile. When the card pushing rod 4 completes pushing the cards and swings backward, the card pushing head 44 also plays a role of blocking the card outlet of the conveying channel.

[0060] In this embodiment, the rotation radius of the card pushing bearing 3 determines the swing amplitude of the card pushing rod 4, that is, the length of the card pushing path, that is, the larger the rotation radius, the larger the swing amplitude; but in order to control the radius of the card pushing plate 2 (the larger the radius of the card pushing plate 2, the larger the volume), the card pushing bearing 3 is arranged at the outer edge of the card pushing plate 2 in this embodiment. In this way, the radius of the card pushing plate 2 can be controlled within a smaller range, and the rotation radius of the card pushing bearing 3 can be increased to the greatest extent to match the required swing amplitude of the card pushing rod 4.

[0061] The working principle of the mahjong machine card pushing mechanism of this embodiment is:

[0062] When pushing cards, the motor 1 starts, and the card pushing plate 2 and the card pushing bearing 3 rotate synchronously with the output shaft of the motor 1. In the process of the card pushing bearing 3 rotating around the central axis of the motor 1, the card pushing bearing 3 also rolls in the card pushing slot 41, causing the card pushing rod 4 to swing forward and push the card pile forward; when the card pushing rod 4 reaches the maximum swing amplitude, the card pushing bearing 3 also rotates around the central axis, driving the card pushing rod 4 to swing backward, returning to the starting point of pushing cards, and waiting for the next card pushing.

[0063] Example 2

[0064] like Figure 2 and Figure 3 As shown, this embodiment is a card pushing mechanism of a mahjong machine, which is basically the same as that of embodiment 1, except that it also includes a card holding assembly, and the motor 1 simultaneously drives the card holding assembly to stack the card piles.

[0065] like Figure 4 and Figure 5 Shown, combined Figure 2 and Figure 3 It can be seen that the card receiving assembly of this embodiment includes a card receiving cam 6 fixedly mounted on the output shaft of the motor 1, and a card receiving curved groove 61 is recessed on the outer peripheral wall of the card receiving cam 6; the card receiving assembly also includes a card receiving platform 7, and the card pushing rod 4 is used to push the card pile on the card receiving platform 7; the card receiving platform 7 is provided with a card receiving bearing 8 which is in rolling or sliding cooperation with the card receiving curved groove 61.

[0066] When applied to a mahjong machine, the card receiving platform 7 is lifted and lowered on the card storage bracket 5. When the card receiving cam 6 rotates, the card receiving bearing 8 rolls to different positions of the card receiving curved groove 61, thereby bringing the card receiving platform 7 to different heights, and finally completing the card stacking action.

[0067] The difference between this embodiment and the first embodiment is that: the card pushing plate 2 is no longer provided separately, but the card receiving cam 6 is directly used as the card pushing plate 2, and the card pushing bearing 3 is rotatably mounted on the top end surface of the card receiving cam 6. Of course, it is also feasible to provide the card receiving cam 6 and the card pushing plate 2 together on the output shaft of the motor 1, but the former has a simpler structure.

[0068] like Figure 4 and Figure 5As shown, in this embodiment, the card receiving curved groove 61 on the card receiving cam 6 includes a horizontal section 61a, a descending curved section 61b and an ascending curved section 61c which are arranged in sequence and connected end to end. The card receiving platform 7 has a first working position guided by the horizontal section 61a to remain stationary so that the card pushing rod 4 pushes the card and then receives the first mahjong tile, a second working position guided by the descending curved section 61b to descend to receive the remaining mahjong tiles, and a third working position guided by the ascending curved section 61c to rise to return to the initial position; accordingly, the card pushing rod 4 has a first working position for pushing cards as the card receiving platform 7 remains stationary, a second working position for returning to the starting point of card withdrawal as the card receiving platform 7 descends or as the card receiving platform 7 receives the first mahjong tile and descends, and a third working position for retreating as the card receiving platform 7 rises and returns to the starting point of card pushing again.

[0069] The working principle of a mahjong machine card pushing mechanism in this embodiment is as follows:

[0070] In a card stacking process, the initial position and the end position of the card receiving platform 7 are both at the highest point in its lifting stroke, which is exactly at the card outlet of the conveying channel. When the card receiving platform 7 completes the stacking of a pile of cards, the card receiving bearing 8 is in the horizontal section 61a of the card receiving curved groove 61, and the card pushing rod 4 is at the starting point of pushing cards (such as Fig.10 As shown in FIG. 1 , as the card receiving cam 6 and the card pushing plate 2 rotate, the card receiving bearing 8 rolls in the horizontal section 61a, so the card receiving table 7 keeps its height unchanged and is in a stationary state, but the card pushing rod 4 is driven by the card pushing bearing 3 to swing, pushing the card pile 100 forward into the card storage track 53 (as shown in FIG. Fig.11 shown);

[0071] After the card-pushing rod 4 passes over the card-receiving platform 7, the card-receiving bearing 8 is still in the horizontal section 61a, and the card-receiving platform 7 remains stationary and receives the first mahjong tile; however, after the card-receiving platform 7 receives the first mahjong tile 200, the card-receiving bearing 8 enters the downward curve section 61b, driving the card-receiving platform 7 to descend. Therefore, although the card-pushing rod 4 is driven by the card-pushing bearing 3 to swing in the opposite direction at this time, it still does not interfere with the card-receiving platform 7 and the first mahjong tile thereon; and, in the process of returning, the head end of the card-pushing rod 4 blocks the card outlet of the conveying channel, so the second mahjong tile does not fall;

[0072] When the card receiving platform 7 drops to the lowest point, the card pushing rod 4 also returns to its card pushing starting point (such as Fig.12 As the card bearing 8 enters the upward curve section 61c, the card bearing platform 7 also rises, and receives the second mahjong tile 300 during the rising process; at the same time, the card push rod 4 is driven by the card push bearing 3 to swing backward by a certain amplitude (such as Fig.13 As shown in the figure, the pusher rod 4 is swung to the starting point of the push card, so as not to affect the rise of the card receiving platform 7 carrying two mahjong tiles; when the card receiving platform 7 returns to the highest point, the pusher rod 4 also swings to the starting point of the push card, as shown in the figure. Fig.10Shown, the card pile can be pushed forward into the card storage track 53 subsequently.

[0073] Example 3

[0074] like Figure 8 and Fig. 9 As shown, when the card pushing mechanism of embodiment 1 or 2 is applied to a mahjong machine, the card pushing mechanism can be directly installed on a Figure 6 The card storage bracket 5 is shown. The card storage bracket 5 is formed with an arc-shaped card storage track 53, and a card receiving platform 7 is installed at the card inlet of the card storage track 53. When the card pushing rod 4 swings, the card pushing head 44 can push the card pile on the card receiving platform 7 into the card storage track 53.

[0075] like Figure 6 and Figure 7 Shown, combined Fig. 9 It can be seen that the card storage bracket 5 of this embodiment is integrally formed with a first groove 54 and a second groove 55, wherein the card pushing plate 2 (or the card receiving cam 6) and the card pushing rod 4 are arranged in the first groove 54; a through hole 56 is opened at the bottom of the first groove 54, and after the motor 1 is fixedly installed to the bottom of the card storage bracket 5, the output shaft of the motor 1 extends into the first groove 54 from the through hole 56 and is connected with the card pushing plate 2 or the card receiving cam 6.

[0076] Depend on Figure 7 , Figure 8 and Fig. 9 It can be seen that the first groove 54 has two groove portions with different depths, wherein the card receiving cam 6 is located in the lower deeper groove portion, and the card pushing rod is located in the upper shallower groove portion.

[0077] The card receiving platform 7 is lifted and lowered in the second groove 55, and the two are connected in the following manner: the bottom of the card receiving platform 7 is provided with at least one guide rod 71, and the card storage bracket 5 is formed with a guide channel 57 which is matched with the guide rod 71 one by one; at the same time, the second groove 55 and the first groove 54 are interconnected, so that the card receiving bearing 8 on the card receiving platform 7 can be inserted into the card receiving curved groove 61 of the card receiving cam 6.
