Description

Technical Field

[0001] The utility model belongs to the technical field of mahjong machines and relates to a conveying mechanism of a mahjong machine. Background Art

[0002] In the prior art, there is no power mechanism connecting the card outlet of the card suction mechanism and the card pushing mechanism of the mahjong machine. The mahjong tiles need to be moved to the card pushing mechanism through the power of the card suction mechanism. When a single mahjong tile is loaded, it is easy for the mahjong tile to be stuck between the card outlet of the card suction mechanism and the card pushing mechanism due to insufficient power of the card suction mechanism.

[0003] For example, a Chinese patent discloses a card loading mechanism and a mahjong machine [application number: 201610992840.X], wherein a card loading mechanism includes a card conveying mechanism, a card loading track, a card loading plate, and a card pushing mechanism for driving mahjong cards to move in the card loading track, wherein the card loading track extends from the card outlet of the card conveying mechanism in an arc-shaped trajectory in a counterclockwise direction to the card loading port of the card loading plate, and the card loading plate and the card conveying mechanism connected to both ends of the card loading track are located on the same side of the mahjong machine. In the mahjong machine of the above structure, the card conveying mechanism, the card loading track, and the card loading plate in the same group of card loading mechanisms are all located on the same side of the mahjong machine, and there is no intersection between adjacent card loading mechanisms. Utility Model Content

[0004] The purpose of the utility model is to provide a conveying mechanism for a mahjong machine in view of the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A conveying mechanism for a mahjong machine comprises an auxiliary conveyor belt arranged below a card outlet of a card loading channel, wherein the auxiliary conveyor belt is sleeved on two pulleys, and a tensioning component is arranged between the two pulleys to increase the linear distance between the two pulleys so that the auxiliary conveyor belt can be in a tensioned state.

[0007] In the above-mentioned conveying mechanism of a mahjong machine, the top of the upper pulley is flush with the bottom of the card loading channel, and the tensioning assembly is connected to the lower pulley to drive the lower pulley away from the upper pulley.

[0008] In the above-mentioned mahjong machine conveying mechanism, the tensioning assembly includes a spring, which is connected to the connecting shaft of the pulley located on the lower side and can apply a force to the connecting shaft away from the pulley located on the upper side, and the connecting shaft and the pulley are rotatably matched.

[0009] In the above-mentioned mahjong machine conveying mechanism, it also includes a pulley mounting seat, in which an adjustment groove is provided that slides with the connecting shaft and forms a circumferential limit. When the connecting shaft slides in the adjustment groove, the straight-line distance between the two pulleys will increase or decrease. Two spring mounting grooves that are arranged parallel to the adjustment groove are also provided on both sides of the pulley mounting seat, and the springs are arranged in the spring mounting grooves.

[0010] In the above-mentioned conveying mechanism of a mahjong machine, the adjusting chute is inclined toward the side close to the card loading channel.

[0011] In the above-mentioned conveying mechanism of a mahjong machine, the two ends of the spring installation groove are a closed end and an open end respectively, and the spring is arranged between the connecting shaft and the closed end.

[0012] In the above-mentioned mahjong machine conveying mechanism, when the closed end is located on the side of the spring installation groove away from the pulley located on the upper side, the force applied by the spring to the connecting shaft is a tensile force and the two ends of the spring are fixedly connected to the connecting shaft and the closed end respectively;

[0013] When the closed end is located at the side of the spring installation groove close to the pulley located at the upper side, the force applied by the spring to the connecting shaft is thrust.

[0014] In the above-mentioned mahjong machine conveying mechanism, it also includes a cover body, the card loading channel is formed in the cover body, the pulley mounting seat is fixed in the cover body, and the cover body is also provided with a drive connected to the central axis at the axis of the pulley on the upper side.

[0015] In the above-mentioned mahjong machine conveying mechanism, a card suction mechanism is arranged on the card entry side of the card entry channel, the card exit of the card entry channel is connected to the card pushing mechanism, and the auxiliary conveyor belt is arranged between the card suction mechanism and the card pushing mechanism.

[0016] In the above-mentioned conveying mechanism of a mahjong machine, a transition support seat is arranged between the card suction mechanism and the auxiliary conveyor belt.

[0017] Compared with the existing technology, the advantages of the utility model are:

[0018] 1. When the mahjong tiles move in the front half of the card-loading channel, they are driven by the power of the card-sucking mechanism. At the card-discharging port of the card-loading channel, i.e., at the inertial transmission stage of the mahjong tiles in the card-loading channel, a reciprocating auxiliary conveyor belt is arranged to assist the loading of the mahjong tiles to prevent the mahjong tiles from being stuck between the card-discharging port of the card-sucking mechanism and the card-pushing mechanism. The tensioning component can drive the linear distance between the two pulleys to increase so that the auxiliary conveyor belt can be in a tensioned state to prevent the belt from being loose.

[0019] 2. The rotation coordination between the connecting shaft and the pulley can ensure that the connecting shaft remains fixed while the pulley can rotate. The straight-line distance between the two pulleys can be increased by applying force to the connecting shaft through the spring. The connecting shaft can slide in the pulley mounting seat by adjusting the slide groove so that the straight-line distance between the two pulleys can be increased or decreased. The circumferential limit formed by adjusting the slide groove and the connecting shaft can prevent the connecting shaft from rotating.

[0020] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] like Figure 1-Figure 5 As shown, a conveying mechanism of a mahjong machine includes an auxiliary conveyor belt arranged below the card outlet of a card loading channel 1, wherein the auxiliary conveyor belt is sleeved on two pulleys 2, and a tensioning component 3 is arranged between the two pulleys 2 to increase the straight-line distance between the two pulleys 2 so that the auxiliary conveyor belt can be in a tensioned state.

[0028] In the utility model, when the mahjong tiles move in the front half of the card-loading channel 1, they are driven by the power of the card-sucking mechanism. At the card-discharging port of the card-loading channel, i.e., at the inertial transmission stage of the mahjong tiles in the card-loading channel, a reciprocating auxiliary conveyor belt is arranged to assist in the loading of the mahjong tiles, so as to prevent the mahjong tiles from being stuck between the card-discharging port of the card-sucking mechanism and the card-pushing mechanism. The tensioning component 3 can drive the linear distance between the two pulleys 2 to increase so that the auxiliary conveyor belt can be in a tensioned state, so as to prevent the auxiliary conveyor belt from being loose.

[0029] Specifically, the top of the upper pulley 2 is flush with the bottom of the card loading channel 1, and the tensioning assembly 3 is connected to the lower pulley 2 to drive the lower pulley 2 away from the upper pulley 2. The tension of the auxiliary conveyor belt can be adjusted by adjusting the positions of the upper and lower pulleys, but in actual applications, since the upper pulley needs to be kept flush with the card loading channel, the tensioning assembly is used in this application to adjust the position of the lower pulley to adjust the tension of the auxiliary conveyor belt.

[0030] Specifically, the tensioning assembly 3 includes a spring 4, which is connected to the connecting shaft 5 of the pulley 2 located at the lower side and can apply a force to the connecting shaft 5 away from the pulley 2 located at the upper side, and the connecting shaft 5 and the pulley 2 are rotationally matched. The rotational match between the connecting shaft 5 and the pulley 2 can ensure that the connecting shaft remains fixed while the pulley can rotate, and the force applied to the connecting shaft 5 by the spring 4 can increase the linear distance between the two pulleys.

[0031] Specifically, it also includes a pulley mounting seat 6, wherein the pulley mounting seat 6 is provided with an adjustment slot 7 that is slidably matched with the connecting shaft 5 and forms a circumferential limit, and when the connecting shaft 5 slides in the adjustment slot 7, the linear distance between the two pulleys 2 will increase or decrease, and two spring mounting slots 13 that are arranged parallel to the adjustment slot 7 are also provided on both sides of the pulley mounting seat 6, and the spring 4 is arranged in the spring mounting slot 13. The adjustment slot 7 enables the connecting shaft to slide in the pulley mounting seat 6 so that the linear distance between the two pulleys 2 can be increased or decreased, and the adjustment slot 7 and the connecting shaft form a circumferential limit to prevent the connecting shaft from rotating.

[0032] Specifically, the adjustment slide groove 7 is tilted toward the side close to the card loading channel 1 .

[0033] Specifically, the two ends of the spring installation groove 13 are a closed end and an open end respectively, and the spring 4 is arranged between the connecting shaft 5 and the closed end.

[0034] In this application, if Figure 5 As shown, when the closed end is located on the side of the spring mounting groove 13 away from the pulley 2 located on the upper side, the force applied by the spring 4 on the connecting shaft 5 is a tensile force. Since the force applied is a tensile force, the two ends of the spring 4 need to be fixedly connected to the connecting shaft 5 and the closed end respectively.

[0035] In addition, when the closed end is located on the side of the spring mounting groove 13 close to the pulley 2 located on the upper side, the force exerted by the spring 4 on the connecting shaft 5 is a thrust. At this time, the spring and the connecting shaft and the closed end can be movably connected or fixedly connected.

[0036] Specifically, it also includes a cover body 8, the card loading channel 1 is formed in the cover body 8, the pulley mounting seat 6 is fixed in the cover body 8, and the cover body 8 is also provided with a driver connected to a central shaft 9 at the axis of the upper pulley 2. The driver can drive the central shaft to rotate, and the rotation of the central shaft can drive the pulley to rotate, thereby driving the auxiliary conveyor belt to reciprocate.

[0037] Those skilled in the art should understand that the driver may be a rotary cylinder or a motor, etc. Preferably, a motor is used in this embodiment.

[0038] Specifically, a card suction mechanism 10 is provided on the card entry side of the card entry channel 1, the card exit of the card entry channel 1 is connected to a card pushing mechanism 11, the auxiliary conveyor belt is provided between the card suction mechanism 10 and the card pushing mechanism 11, and a transition support seat 12 is provided between the card suction mechanism 10 and the auxiliary conveyor belt.

[0039] 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.
