Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-5, the embodiment of the present invention is an improved mahjong tile stacking mechanism, which comprises a tile stacking groove 1, and a tile picking and conveying assembly 2 composed of a front roller, a rear roller 201, a driving unit and a belt 202 wound around the rollers; the mahjong tile stacking groove 1 is arranged in front of the rear end roller 201, the position of the mahjong tile stacking groove 1 relative to the rear end roller 201 is fixed, and the distance between the horizontal position of the groove bottom of the mahjong tile stacking groove 1 and the horizontal position of the conveyor belt at the upper end of the rear end roller 201 is larger than the thickness of a mahjong tile 8; the distance between the vertical position of the card folding groove 1 far away from the side wall 5 of the rear end roller 201 and the vertical position of the tail end of the rear end roller 201 is more than the length of one mahjong tile 8; the magnetic attraction object 6 for ensuring the magnetic attraction mahjong tiles 9 to lie in a directional mode is laid at the bottom of the tile stacking groove 1, and the magnetic attraction object 6 and the magnetic attraction mahjong tiles 9 are in an attraction relationship in a face-to-face mode. Wherein the conveyor belt is a wide belt or a circular belt.

In order to reduce noise, a noise reduction layer 3 is laid on the magnetic attraction object 6. When the mahjong tiles fall into the tile stacking groove, the mahjong tiles can receive certain acting force to impact the magnetic attraction object under the action of gravity and magnetic force, and the buffer effect and the noise reduction can be effectively realized through the noise reduction layer.

In order to complete the operation of stacking and pushing the mahjong tiles, the tail end of the mahjong tile stacking groove 1 is connected to the mahjong tile bearing frame 4, after the mahjong tile stacking groove 1 completes the stacking of the mahjong tiles, the mahjong tile stacking groove 1 is kept still, and the mahjong tile pushing mechanism 7 pushes the stacked mahjong tiles 9 to the mahjong tile bearing frame 4. The stacked mahjong tiles can be pushed out and then lifted to a table top for placement through the tile pushing mechanism and the tile bearing frame.

Compared with the prior card picking and stacking mechanism of the applicant, the magnetic attraction point does not need to be arranged on the transmission belt or the rear-end roller, so that the production cost is lower; the mahjong tiles directly fall into the tile stacking groove, so that the mahjong tiles do not need to be turned over, and the operation efficiency is higher; because need not the upset, the horizontal position distance of the tank bottom of fold tablet groove and the horizontal position distance that is located rear end gyro wheel upper end conveyer belt is greater than the thickness of a mahjong tile, compares preceding technique, and this application can be made highly littleer, thinner.

In order to further ensure that the mahjong tiles can stably fall into the tile stacking groove, the side wall 5 of the tile stacking groove 1, which is far away from the rear-end roller, is of a vertical baffle structure, and the highest position of the baffle structure is higher than that of the mahjong tiles in the first layer. When the side wall is short or not, the mechanism can be normally used, and mahjong tiles can accurately fall into the tile stacking groove under the action of magnetic force and friction force when falling, but can be transversely displaced. When the highest position of the side wall is higher than that of the first layer of mahjong tiles, the side wall can transversely block the first layer of mahjong tiles when the mahjong tiles fall down, and the second layer of mahjong tiles can also transversely block the second layer of mahjong tiles when the mahjong tiles fall down, so that the mahjong tiles can fall into the tile stacking groove more accurately and smoothly.

The mahjong tile stacking groove is ingeniously arranged below the mahjong tile picking and conveying assembly, the self gravity of the mahjong tiles and the magnetic adsorption force of the magnetic adsorption object on the mahjong tiles are fully utilized, the mahjong tiles can accurately and stably fall into the mahjong tile stacking groove, and accordingly the mahjong tiles can be well stacked without a lifting mechanism; the mahjong machine has a simple structure, is easy to produce and maintain, saves a large number of control components and lifting driving pieces, and greatly reduces the manufacturing cost of the mahjong machine; meanwhile, the vertical structure of the tile stacking groove and the conveying mechanism fully utilizes the three-dimensional space, so that the utilization of the plane space is reduced, the comprehensive layout transformation of the automatic mahjong machine is facilitated, and the design space of the automatic mahjong machine is greatly expanded.

The above, only do the preferred embodiment of the present invention, not used to limit the present invention, all the technical matters of the present invention should be included in the protection scope of the present invention for any slight modification, equivalent replacement and improvement of the above embodiments.
