SUMMERY OF THE UTILITY MODEL
The invention aims to provide a mahjong tile feeding system of a full-automatic mahjong machine, which has a simple structure and is convenient to process, assemble and maintain.
In order to achieve the purpose, the technical scheme of the utility model is as follows:
a tile feeding system of a full-automatic mahjong machine comprises a rack, wherein two tile lifting and supporting plates are rotatably connected to each side of the rack, and a combined driving mechanism for driving the two tile lifting and supporting plates on the same side of the rack to turn is further mounted on the rack; each of the raising and holding plates has a raising preparation position where the free end is lowered to receive the mahjong tiles and a raising and holding position where the free end is raised to raise the mahjong tiles;
the combined driving mechanism comprises a circumferential driver, two rocker arms which are in one-to-one correspondence with the mahjong lifting and supporting plates are fixedly installed at the power output end of the circumferential driver, and the circumferential driver is used for driving the rocker arms to rotate in a reciprocating mode so as to drive the corresponding mahjong lifting and supporting plates to switch between a mahjong lifting preparation position and a mahjong lifting and supporting position.
The utility model discloses two rocking arms that are in the card board that holds of rising of power take off end installation at same circumference driver, under the drive of circumference driver, two rocking arms rotate in step to can drive two free ends that rise the card board and hold the card board and take place to go up and down. The combined driving mode does not need to provide a hole groove with higher precision and does not need precise parts used in a matching way, and only needs to correspond the position of the rocker arm to the position of the tile lifting and bearing plate, so that the rocker arm can drive the free end of the tile lifting and bearing plate to lift; not only saves raw materials, but also is convenient for processing, assembling, maintaining and replacing parts and reduces the cost.
For the over-the-top vehicle type card feeding system, each card lifting and bearing plate needs to be in butt joint with different card feeding tracks, and the positions of the two card lifting and bearing plates on the same side of the rack are different in order to ensure that cards are lifted simultaneously when the radians of the card feeding tracks are different; meanwhile, in order to make the full-automatic mahjong machine smaller in size and more compact in structure, the two tile lifting and supporting plates are arranged in a staggered mode. In these cases, since the hinged positions of the card-lifting and holding plates and the frame are in the same plane, there is a difference in the lifting heights of the two card-lifting and holding plates, so that different transmission members need to be arranged between the rocker arms and the corresponding card-lifting and holding plates.
In the mahjong loading system of the full-automatic mahjong machine, the free ends of the two mahjong lifting and supporting plates have different lifting heights in the same direction of the rack; a first transmission piece is arranged between the mahjong lifting and supporting plate with higher lifting height and the corresponding rocker arm, and a second transmission piece is arranged between the mahjong lifting and supporting plate with lower lifting height and the corresponding rocker arm.
Different transmission parts are arranged to ensure that the two card lifting and supporting plates reach the lifting terminal point at the same time point. The card-raising and holding plate with a higher lifting height should have a relatively slower lifting speed, and the card-raising and holding plate with a lower lifting height should have a relatively slower lifting speed.
In the tile feeding system of the full-automatic mahjong machine, the first transmission piece comprises a first transmission plate arranged on the bottom surface of the tile lifting and supporting plate, a first transmission curved surface acting with the rocker arm is formed on the first transmission plate, and the first transmission curved surface comprises a rapid lifting inclined surface section and a first stop curved surface section which are sequentially connected. When the rocker arm moves along the rapid lifting inclined plane section, the card lifting and supporting plate with higher lifting height can lift at a higher speed, and the first stop curved surface section is used for limiting the reverse rotation end point of the rocker arm so as to ensure that the card lifting and supporting plate is in a horizontal and stable card supporting state.
When the tile lifting and supporting plate is lifted, the rocker arm moves from the top end of the rapid lifting inclined plane section to the bottom end of the rapid lifting inclined plane section; when the mahjong lifting and supporting plate descends, the rocker arm moves from the bottom end of the rapid lifting inclined plane section to the top end of the rapid lifting inclined plane section, and the rocker arm easily slides downwards along the rapid lifting inclined plane section due to insufficient stress, so that the circumferential driver fails to work.
Therefore, in the tile feeding system of the full-automatic mahjong machine, the first transmission curved surface further comprises a first lifting plane section connected with the rapid lifting inclined plane section, the first lifting plane section is close to the free end of the tile lifting and supporting plate and is parallel to the tile lifting and supporting plate, and the rapid lifting inclined plane section extends from the first lifting plane section to one side far away from the tile lifting and supporting plate.
When the card lifting and supporting plate descends, the first lifting plane section can prop against the rocker arm to prevent the rocker arm from sliding downwards along the rapid lifting inclined plane section; when the mahjong lifting and supporting plate rises, the first lifting plane section can also slow down the rising speed of the mahjong lifting and supporting plate during initial mahjong lifting, and the mahjong scattering caused by rapid rising in the whole mahjong lifting process is avoided.
In the tile feeding system of the full-automatic mahjong machine, the second transmission part comprises a second transmission plate arranged on the bottom surface of the tile lifting and supporting plate, a second transmission curved surface acting with the rocker arm is formed on the second transmission plate, and the second transmission curved surface comprises a slow lifting curved surface section and a second stop curved surface section which are sequentially connected. The function of the second stop curved surface section is the same as that of the first stop curved surface section, and the second stop curved surface section and the first stop curved surface section are used for limiting the reverse rotation end point of the corresponding rocker arm; and the slow lifting curved surface section can slow down the lifting speed of the card lifting and supporting plate.
In the tile feeding system of the full-automatic mahjong machine, the slow lifting curved surface section comprises a second lifting plane section and a slow lifting inclined plane section which are connected with each other, the second lifting plane section is close to the free end of the tile lifting and supporting plate and is arranged in parallel with the tile lifting and supporting plate, and the slow lifting inclined plane section extends from the second lifting plane section to one side close to the tile lifting and supporting plate.
The second lifting plane section has the same function as the first lifting plane section, so that the lifting speed of the tile lifting and supporting plate is reduced, and the rocker arm is prevented from being insufficiently stressed when the tile lifting and supporting plate descends. The inclined direction of the slow lifting inclined plane section is opposite to that of the fast lifting inclined plane section so as to counteract the fast lifting of the mahjong lifting and supporting plate caused by the movement of the rocker arm along the fast lifting inclined plane section, and the mahjong lifting and supporting plate with lower lifting height always keeps lower lifting speed.
In order to simplify the driving procedure, in the mahjong-dealing system of the full-automatic mahjong machine, the two rocker arms are positioned in the same radial direction of the power output end of the circumferential driver.
In the tile feeding system of the full-automatic mahjong machine, the second lifting plane section and the first lifting plane section are positioned on the same plane. Therefore, the lengths of the two rocker arms can be set to be the same or equivalent, and the requirements on rocker arm parts are reduced.
In the tile serving system of the full-automatic mahjong machine, the inclination angle of the slow lifting inclined plane section relative to the plane where the second lifting plane section is located is smaller than that of the fast lifting inclined plane section relative to the plane where the first lifting plane section is located, and the starting points of the slow lifting inclined plane section and the fast lifting inclined plane section and the terminal points of the slow lifting inclined plane section and the fast lifting inclined plane section are all located in the same radial direction of the power output end of the circumferential driver.
The reason that the slope of the slow lifting slope section is smaller than that of the fast lifting slope section is that the lifting process of the mahjong lifting and supporting plate with a lower lifting height is more stable, and the too large slope of the slow lifting slope section can cause the too low lifting speed of the corresponding mahjong lifting and supporting plate.
In the mahjong-feeding system of the full-automatic mahjong machine, the second stop curved surface section and the first stop curved surface section are positioned in the same radial direction of the power output end of the circumferential driver. Thus, the two card lifting and supporting plates can be lifted to the top surface of the rack and converted into a horizontal state.
In the tile feeding system of the full-automatic mahjong machine, a first type groove and a second type groove are formed on the rack, the first type groove is used for installing a tile lifting and bearing plate with higher lifting height, and the second type groove is used for installing a tile lifting and bearing plate with lower lifting height;
at least a support piece used for supporting the free end of the tile lifting and bearing plate is arranged in the first groove, and through holes for the rocker arms to penetrate through are formed in the bottom surfaces of the first groove and the second groove.
Generally, the depth of the first groove and the second groove on the frame is the same, so that the processing is convenient; therefore the utility model discloses at least at first type inslot setting support piece, when the free end that has lower elevating height and rises the tablet board of holding descends, support piece can support the free end to fix a position it in predetermineeing the position.

In the tile feeding system of the full-automatic mahjong machine, the tail end of the rocker arm is rotatably connected with a roller which is matched with the tile lifting and supporting plate in a rolling way. The rolling fit of the roller is utilized to replace the friction fit of the rocker arm, so that the whole moving process of the rocker arm is smoother, and the abrasion of the friction to the rocker arm can be greatly reduced.
