Mahjong machine

Abstract

The invention discloses a mahjong machine which comprises a base plate, panels, mahjong lifting support plates, a mahjong shuffling plate, mahjong taking and conveying mechanisms and a mahjong pushing and lifting mechanism. Four mahjong taking and conveying mechanisms and four mahjong lifting support plates are installed on a conveying base which is an integrally-formed part provided with four groups of positioning and installing portions. The four groups of positioning and installing portions are centrally symmetrical, each group of positioning and installing portions comprises a conveying and installing portion, a panel installing portion and a guiding shaft seat portion, wherein the conveying and installing portions and the mahjong taking and conveying mechanisms achieve positioning and are locked and fixed through fasteners, and the top ends and panels of the panel installing portions achieve positioning. The guiding shaft seat portions are arranged on the outer sides of the conveying and installing portions, two guiding rods under the mahjong lifting support plates are respectively and vertically inserted into two shaft holes of the guiding shaft seat portions, and the mahjong pushing and lifting mechanism pushes the mahjong lifting support plates to lift. By means of the technical scheme, the panels and the mahjong lifting support plates are positioned on the same part, accordingly the matching requirement of the panels and the mahjong lifting support plates is guaranteed, machine adjustment is decreased, the matching accuracy is improved, and the deformation influence is reduced.

Description

technical field [0001] The invention relates to a mahjong machine. 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 cards. Mechanism, the stacking mechanism is located...

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.
