Technical Field

The invention relates to the field of full-automatic mahjong, in particular to an integrated conveying and tile discharging structure.

Background

The existing full-automatic mahjong machine conveying and tile discharging mechanism adopts the following steps: the mahjong tile conveying mechanism comprises a conveying mechanism, a tile discharging mechanism and a tile conveying mechanism, wherein the conveying mechanism is connected with the tile discharging mechanism, and the tile conveying mechanism is connected with the tile discharging mechanism.

Wherein, conveying mechanism adopts: the four conveying mechanisms are independent from each other and connected at 90 degrees, and each conveying mechanism comprises a tile sucking and conveying device driven by a motor and used for picking up and conveying the mahjong tiles to the tile outlet. The card-playing mechanism adopts the following steps: the motor drives the gear set to drive the double rocker arms to act on the tile lifting structure, and the structure limits the tile lifting structure to only do vertical motion through the two guide rods and the corresponding guide sleeves, so that the sinking and lifting actions of the tile lifting mechanism are realized; meanwhile, the cam is driven to rotate through the gear set, the cam pushes the swing rod to move, and finally the tail end of the swing rod drives the tile pushing plate of the tile pushing mechanism to horizontally move on the two horizontal guide rods, so that the tile pushing is realized.

However, the prior structure has the following problems: 1. the transport structure is composed of a plurality of parts, in particular housing parts, which are joined together to form a housing, which increases the production costs and also the assembly costs. 2. The card lifting and pushing mechanism uses the guide sleeve and the guide rod, the precision requirement is high, and the cost is increased. If the guide sleeve and the guide rod can not be well matched during assembly, the situation that the movement mechanism slides unsmoothly or even is blocked can be caused, and at the moment, an experienced worker is often needed to correct the movement mechanism a little by little through knocking, so that the assembly difficulty, time and assembly cost are increased. After the guide sleeve and the guide rod are used for a period of time, the mechanism can be jammed or even dead due to deformation and consumption of lubricating grease, and the normal service life of the machine is influenced. 3. The used gear is a plastic gear, so that the precision is low, the meshing clearance is large, the rotation lag is easy to generate, and the abrasion is more serious after a period of time. This lag prevents the dual rockers from rotating synchronously, which in turn causes the card lifting mechanism to be stressed unevenly. In addition, the matching relationship between the guide rod and the guide sleeve has higher requirement on the stress condition, and the situations of jamming and uneven surface between the outer surface of the card lifting mechanism and the table top can occur. In order to solve these problems, adjustment by knocking and adding a spacer is required at the time of assembly, which is very time consuming. The user experience is affected by the problem during the use process. 4. Due to the fact that control over precision is low in the industry, perfect operation effect of each part after assembly is difficult to achieve, and a large amount of later-stage debugging is needed. Such as the adjustment between the lifting guide rod and the guide sleeve and the adjustment of the position of the card pushing plate in the card pushing structure. These adjustments increase labor and extend production cycle time, ultimately resulting in increased costs.
