Mahjong machine and card fetching and conveying device thereof

Abstract

The invention discloses a mahjong machine and a card fetching and conveying device thereof. The Mahjong machine comprises a conveying base, four card fetching and conveying mechanisms and four card lifting and supporting plates are installed on the periphery of the conveying base in a positioning mode, the conveying base is an integrally molded member with four groups of positioning installation portions, centers of the four groups of positioning installation portions are arranged symmetrically, each group of positioning installation portion comprises a conveying installation portion, a panel installation portion and a guide sleeve base portion, the conveying installation portions and the card fetching and conveying mechanisms are positioned and fixedly fastened through fasteners, the top ends of the panel installation portions and panels are positioned, the guide shaft base portions are arranged on the outer sides of the conveying installation portions, and two guide rods below each card lifting and supporting plate are respectively and vertically inserted in two shaft holes of each guide shaft base portion. According to the technical scheme, the panels and the card lifting and supporting plates are installed on the conveying base in the card fetching and conveying device in a positioning mode, therefore matching requirements of the panels and the card lifting and supporting plates are guaranteed, machine debugging is reduced, matching accuracy is improved, and deformation influence is reduced.

Description

technical field [0001] The invention relates to a mahjong machine and a card picking and conveying device thereof. Background technique [0002] The mahjong machine generally includes a mahjong machine host installed on the bottom plate, a frame is installed around the mahjong machine host, the frame is generally composed of four frame components, and a panel is installed above the mahjong machine host. Taking the four-port Mahjong machine as an example, the main machine of the mahjong machine includes four ascending boards arranged in the shape of a windmill, and the board is connected with the lifting board mechanism, and a rotatable shuffling plate is installed on the bottom plate. , The card-taking conveying mechanism is installed around the shuffling plate. The card-taking conveying mechanism includes a conveying trough and a conveyor belt arranged above the four sides of the shuffling plate. The entrance of the conveying trough is equipped with a magnet for taking card...

AI Technical Summary

Problems solved by technology

[0004] 1. It greatly increases the cost of manual debugging and machine manufacturing, and increases the difficulty of subsequent maintenance of the machine

[0005] 2. In the above structure, all the mechanisms are positioned and installed on the large-size bottom plate, especially the positioning and coordination between the lifting plate and the rising plate on the panel needs to go through the cooperation between the lifting plate and the guide shaft seat→the guide shaft seat The cooperation with the mounting bracket of the push-up mechanism → the cooperation between the mounting bracket of the push-up mechanism and the bottom plate → the cooperation between the bottom plate and its four corner support columns → the cooperation between the support column and the panel can be realized. If the matching path is too long, the matching error will accumulate and enlarge, which will eventually lead to The positioning accuracy of the lifting card support plate and the lifting card opening on the panel cannot be guaranteed, which increases the difficulty of machine adjustment

[0006] 3. During the transportation and use of the mahjong machine, the bottom plate will inevitably have different degrees of deformation. In addition, due to factors such as ambient temperature, the bottom plate and its components of various materials will also experience different degrees of thermal expansion and contraction deformation. Due to the excessively long matching path and the excessively large size of the bottom plate, the accumulation of deformation is enlarged, which eventually leads to the inability to cooperate between the lifting card support plate and the lifting card opening on the panel, and the mahjong machine cannot be used.

Although this structure shortens the machine debugging time to a certain extent, improves production efficiency, and avoids the displacement of internal systems (mechanisms) caused by the use of the machine, it does not have any impact on the original lifting plate and panel. The positioning and matching path of the rising card opening on the upper part has been improved, but there are still problems such as low matching accuracy caused by too long matching path and too large size of the bottom plate, difficult adjustment and easy to be affected by deformation, etc.

Moreover, the entire bottom plate is made of plastic integral injection molding, which has defects such as difficult molding, low support strength, and easy thermal deformation.
