Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mahjong machines, in particular to a flat-pushing card-dealing mechanism of a mahjong machine. Background Technique
[0002] The working principle of a mahjong machine is that the cards with the back facing up are attracted by the magnetic ring on the shuffling barrel, rotate with the magnetic ring and are sent to the conveying groove, and are pushed into stacks by the stacking and pushing motor at the machine head, and are pushed away by the link rod. The cards without magnetism on the front continue to rotate on the disc. The most common one is the four-opening machine.
[0003] The flat-pushing card-dealing mechanism is a component of a mahjong machine. The existing card-pushing components of mahjong machines usually use electric push rods to perform reciprocating pushing, so as to facilitate pushing the stacked cards to the card-dealing mechanism. The electric push rod drives the push block and cannot quickly reset to the initial position, and the card-pushing speed is limited, resulting in poor smoothness. Content of the Utility Model
[0004] (1) Technical Problems to be Solved
[0005] In view of the deficiencies of the prior art, the utility model provides a flat-pushing card-dealing mechanism of a mahjong machine, which solves the problems put forward in the above background technique.
[0006] (2) Technical Solutions
[0007] To achieve the above purposes, the utility model is realized through the following technical solutions: A flat-pushing card-dealing mechanism of a mahjong machine includes a bottom support bar, a rear stop bar and a front stop bar fixed to the top of the bottom support bar. A side stop bar is fixedly connected between the ends of the rear stop bar and the front stop bar. The length of the front stop bar is less than that of the rear stop bar. A strip-shaped opening is formed at the bottom of the bottom support bar. A push block that can move back and forth left and right is slidably arranged between the front stop bar and the rear stop bar. Two horizontally arranged guide rods are fixedly connected to the lower end of the push block. A positioning bar is fixedly connected to the bottom of the bottom support bar. The guide rods movably penetrate through the positioning bar. A spring is fixedly connected between the push block and the positioning bar. The spring is sleeved on the guide rod.
[0008] Preferably, a rack is fixedly connected to the end of the push block. A motor is fixedly connected to the bottom of the bottom support bar. A semi-gear is fixedly connected to the output end of the motor. The semi-gear intermittently meshes with the rack.
[0009] Preferably, a strip-shaped opening is formed at the bottom of the bottom support bar. A push bar is arranged below the bottom support bar. The position of the push bar corresponds to that of the strip-shaped opening. A micro cylinder is fixedly installed at the bottom of the bottom support bar. The output end of the micro cylinder is fixedly connected to the push bar. When the micro cylinder is started, the push bar moves upward through the strip-shaped opening and pushes the mahjong cards to rise.
[0010] Preferably, the surface of the pushing block is provided with a socket, and the pushing bar can pass through the socket.
[0011] Preferably, when the half gear is not in contact with the rack, the distance between the pushing block and the end of the front stop bar is greater than the width of the mahjong tile.
[0012] (III) Beneficial effects
[0013] The utility model provides a flat-pushing and card-loading mechanism for a mahjong machine, which has the following beneficial effects:
[0014] 1. In the utility model, the mahjong tiles are stacked on the bottom support bar through the gap formed between the pushing block and the front stop bar, and then the motor is started to drive the half gear to rotate. When the half gear contacts the rack, the pushing block is pulled to move, and the pushing block pushes the mahjong tiles to move, realizing the flat-pushing and card-loading of the mahjong tiles. When the half gear is no longer in contact with the rack, the spring releases its elastic force to push the pushing block to quickly reset, thus accelerating the speed of pushing the cards, which is very important for rapid card dealing and improving fluency.
[0015] 2. In the utility model, after the mahjong tiles are linearly stacked on the bottom support bar, the micro cylinder is started to push the pushing bar upward, so that the pushing bar enters the strip-shaped opening and contacts the mahjong tiles, pushing the mahjong tiles to move upward and conveying the mahjong tiles to the tabletop of the mahjong machine.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0021] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a flat-pushing card-playing mechanism for a mahjong machine, including a bottom support bar 1, a rear stop bar 2 and a front stop bar 3 fixed to the top of the bottom support bar 1. A side stop bar 4 is fixedly connected between the ends of the rear stop bar 2 and the front stop bar 3. The side stop bar 4 prevents the conveyed mahjong tiles 14 from falling off from this end, achieving the purpose of limiting. The length of the front stop bar 3 is less than that of the rear stop bar 2. A strip-shaped opening 101 is formed at the bottom of the bottom support bar 1. A push block 5 that can move back and forth left and right is slidably arranged between the front stop bar 3 and the rear stop bar 2. Two horizontally arranged guide rods 9 are fixedly connected to the lower end of the push block 5. A positioning bar 11 is fixedly connected to the bottom of the bottom support bar 1. The guide rods 9 movably penetrate through the positioning bar 11. A spring 10 is fixedly connected between the push block 5 and the positioning bar 11. The spring 10 is sleeved on the guide rods 9; when the spring 10 retracts, consider adding damping materials or structures around the positioning bar 11, such as rubber pads or viscous coatings; these materials can absorb the energy of oscillation and prevent unnecessary vibrations when the spring 10 retracts.
[0022] A rack 6 is fixedly connected to the end of the push block 5. A motor 7 is fixedly connected to the bottom of the bottom support bar 1. A half gear 8 is fixedly connected to the output end of the motor 7. The half gear 8 intermittently meshes with the rack 6.
[0023] Stack the mahjong tiles 14 on the bottom support bar 1 through the gap formed between the push block 5 and the front stop bar 3. Then start the motor 7 to drive the half gear 8 to rotate. The half gear 8 contacts the rack 6 and pulls the push block 5 to move. The push block 5 pushes the mahjong tiles 14 to move, realizing the flat-pushing card-playing of the mahjong tiles 14; when the half gear 8 does not contact the rack 6, the spring 10 releases its elastic force and pushes the push block 5 to quickly reset, thus accelerating the speed of pushing the cards, which is very important for quickly dealing cards and improving fluency.
[0024] In order to enable the push block 5 to move linearly normally when pushing the cards, a socket 5�1 is formed on the surface of the push block 5. The push bar 12 can pass through the socket 5�1. In this way, the push block 5 can move along the push bar 12, and finally it can ensure that the mahjong tiles 14 are pushed to the designated position.
[0025] A strip-shaped opening 101 is formed at the bottom of the bottom support bar 1. A push bar 12 is arranged below the bottom support bar 1. The push bar 12 corresponds to the position of the strip-shaped opening 101. A micro cylinder 13 is fixedly installed at the bottom of the bottom support bar 1. The output end of the micro cylinder 13 is fixedly connected to the push bar 12. When the micro cylinder 13 is started, the push bar 12 moves upward through the strip-shaped opening 101 and pushes the mahjong tiles 14 to rise.
[0026] After stacking the mahjong tiles 14 linearly and sequentially on the bottom support bar 1, at this time start the micro cylinder 13 to push the push bar 12 to move upward, so that the push bar 12 enters the strip-shaped opening 101 and contacts the mahjong tiles 14, pushing the mahjong tiles 14 to move upward and conveying the mahjong tiles 14 to the tabletop of the mahjong machine.
[0027] When the half gear 8 is not in contact with the rack 6, the distance between the push block 5 and the end of the front stop bar 3 is greater than the width of the mahjong tile 14, which can ensure the smooth conveyance of the mahjong tile 14 onto the bottom support bar 1.
[0028] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
