Description

Technical Field

[0001] This invention relates to the field of mahjong machine technology, and in particular to a mahjong machine push-lift linkage device. Background Technology

[0002] The working principle of a mahjong machine is that the mahjong tiles with their backs facing up are attracted by a magnetic ring on the shuffling drum, rotate with the magnetic ring and are sent to the conveyor trough, where they are pushed into a pile by a stacking motor at the machine head and pushed away by a chain rod. The tiles with their fronts not being magnetic continue to rotate on the plate (single-player machine principle), which has now been upgraded to a four-player machine.

[0003] In existing technology, when transporting mahjong tiles, the tiles in the shuffling device need to be pushed upwards, and then pushed horizontally for stacking. In these two operating states, two sets of power mechanisms are usually used: one set of power mechanisms to lift the mahjong tiles upwards and the other set of power mechanisms to push the mahjong tiles horizontally. This setup occupies a large amount of internal space, and the large number of power mechanisms increases the failure rate. At the same time, the coordination between the two sets of power mechanisms requires the control device to pre-set the linkage program, which further increases the difficulty of coordination and the setup cost. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a mahjong machine lifting linkage device that can drive the mahjong tiles to move up and down and to move them horizontally through a set of power mechanisms, thereby solving the problems of complex lifting mechanism settings, poor linkage coordination, and high failure rate of existing mahjong machines.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: a mahjong machine push-lift linkage device, comprising a motor, a push mechanism, a lifting mechanism, and a housing, wherein the motor is used to output power to the push mechanism and the lifting mechanism, and the housing is used to connect and install the motor, the push mechanism, and the lifting mechanism;

[0006] The output shaft of the motor is connected to a wheel, and the annular side of the wheel is provided with a groove. A lifting guide shaft is provided on the side of the wheel away from the motor, and the lifting guide shaft is located away from the axis of the wheel.

[0007] The pushing mechanism includes a push rod, a push plate is provided at the top of the push rod, a movable rotating shaft is provided at the middle position of the push rod, and a fixed rotating shaft is provided at the bottom of the push rod; the movable rotating shaft extends into the groove, and the fixed rotating shaft is rotatably connected to the housing.

[0008] The housing has a lifting groove, and the lifting mechanism includes a lifting plate and a support plate. The lifting plate is slidably connected to the lifting groove, and the support plate is set on the top of the lifting plate. A concave guide plate is provided on the side of the lifting plate near the rotating wheel, and the bottom of the concave guide plate is in contact with the lifting guide shaft.

[0009] Furthermore, the concave guide plate is provided with a lower concave portion and an upper convex portion, the upper convex portion is provided on both sides of the lower concave portion, and the setting height of the lower concave portion is lower than the setting height of the upper convex portion.

[0010] Furthermore, a fixed base is provided at the bottom of the housing, and the fixed rotating shaft is rotatably connected to the fixed base.

[0011] Furthermore, a guide wheel is provided on one side of the push plate, and a guide groove is provided on the housing. The guide wheel extends into the guide groove and is slidably connected to the guide groove.

[0012] Furthermore, a guide connecting block is rotatably connected to the movable shaft, and the guide connecting block is in rolling connection with the groove.

[0013] Furthermore, a torsion spring is provided on one side of the housing, with one top end of the torsion spring connected to the lifting plate and one bottom end of the torsion spring connected to the housing.

[0014] The beneficial effects of this invention are as follows: The output shaft of the motor of this invention is connected to a wheel, and the annular side of the wheel has a groove. A lifting guide shaft is provided on the side of the wheel away from the motor, and the lifting guide shaft is located away from the axis of the wheel. The pushing mechanism is connected to the groove through a movable shaft in the middle of the push plate. When the wheel rotates, it can drive the top of the push plate to reciprocate horizontally. In the lifting mechanism, the concave guide plate of the lifting plate is linked with the lifting guide shaft of the wheel. When the wheel rotates, it can drive the lifting guide shaft to reciprocate up and down. The lifting guide shaft, in cooperation with the concave guide plate, drives the lifting plate to reciprocate up and down, thereby realizing that the motor drives the push plate and the lifting plate to operate simultaneously, which improves the power utilization efficiency and the tightness of the linkage of this device.

[0023] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0024] Please see Figure 1 - Figure 6 As shown, the present invention provides a mahjong machine push-lift linkage device, including a motor 1, a push mechanism, a lifting mechanism 4, and a housing 3. The motor 1 is used to output power to the push mechanism and the lifting mechanism 4, and the housing 3 is used to connect and install the motor 1, the push mechanism, and the lifting mechanism 4.

[0025] The output shaft of motor 1 is connected to a rotating wheel 11. The annular side of the rotating wheel 11 is provided with a groove 111. A lifting guide shaft 112 is provided on the side of the rotating wheel 11 away from motor 1. The lifting guide shaft 112 is located away from the axis of the rotating wheel 11.

[0026] The pushing mechanism includes a push rod 2, a push plate 21 at the top of the push rod 2, a guide wheel 22 on one side of the push plate 21, a guide groove 34 on the housing 3, the guide wheel 22 extending into the guide groove 34 and slidingly connected to the guide groove 34, a movable rotating shaft 24 at the middle position of the push rod 2, a guide connecting block rotatably connected to the movable rotating shaft 24, the guide connecting block rollingly connected to the groove 111, a fixed rotating shaft 23 at the bottom of the push rod 2, a fixed seat 33 at the bottom of the housing 3, the fixed rotating shaft 23 rotatably connected to the fixed seat 33, the movable rotating shaft 24 extending into the groove 111, and the fixed rotating shaft 23 rotatably connected to the housing 3; when the motor 1 rotates, it drives the rotating wheel 11 to rotate, and when the rotating wheel 11 rotates, the movable rotating shaft 24 can reciprocate horizontally along the groove 111. Since the bottom end of the push rod 2 is fixed in relative position through the fixed rotating shaft 23, the top end of the push rod 2 can reciprocate.

[0027] The housing 3 has a lifting groove 32 inside. The lifting mechanism 4 includes a lifting plate and a support plate 41. The lifting plate is slidably connected to the lifting groove 32. The support plate 41 is set on the top of the lifting plate. A concave guide plate 42 is set on the side of the lifting plate near the rotating wheel 11. The bottom of the concave guide plate 42 is in contact with the lifting guide shaft 112. The concave guide plate 42 is provided with a lower concave part and an upper convex part. The upper convex part is set on both sides of the lower concave part. The setting height of the lower concave part is lower than the setting height of the upper convex part. When the motor 1 drives the rotating wheel 11 to rotate, the lifting guide shaft 112 on one side of the rotating wheel 11 can move up and down reciprocally.

[0028] A torsion spring 31 is provided on one side of the housing 3. The top end of the torsion spring 31 is connected to the lifting plate, and the bottom end of the torsion spring 31 is connected to the housing 3. By providing the torsion spring 31, the torsion spring 31 can be compressed when the lifting plate rises, so that the lifting plate can fall quickly.

[0029] Working principle: During operation, motor 1 drives the rotating wheel 11 to rotate. When the rotating wheel 11 rotates, the movable shaft 24 in the middle of the push rod 2 can move back and forth horizontally along the groove 111 of the rotating wheel 11, thereby driving the push plate 21 at the top of the push rod 2 to move back and forth horizontally. At the same time, when the rotating wheel 11 rotates, it can drive the lifting guide shaft 112 to move back and forth up and down. Through the cooperation between the lower concave part and the upper convex part of the concave guide plate 42, the lifting plate can be driven to move back and forth up and down. This realizes that motor 1 drives the lifting and horizontal pushing mechanisms to work together, improving the coordination of the lifting and pushing of the mahjong tiles.
