Problems solved by technology

In addition, since the high-density magnetic block is placed on the end close to the tile surface, the magnetic field strength on the bottom surface of the tile is relatively weak, so when the existing mahjong tiles are stacked in the mahjong machine, there will be sliding stacking phenomenon

Embodiment 1

[0026] Magnetic powder, calcium powder, and resin binder are configured and weighed according to 30%, 68%, and 2% of the total weight respectively. The weighed above-mentioned materials were placed in a mixer and mixed for 20 minutes to form a mixture for use.

[0027] Put the high-density magnetic block, that is, the magnetic steel, in the composite magnetic block mold, then pour the above-mentioned mixture into the composite magnetic block mold, press and demould to form a composite magnetic block blank, and place the blank in a low-temperature oven at 65°C , after 10 hours of drying, take it out for use.

[0028] Put the white amino molding resin powder in the shell mold, then press and demould to form a rectangular mahjong tile shell. The housing is placed in a mold with a cover, and the prefabricated composite magnetic block is put into the housing, and finally the blue amino mold resin powder is placed in the mold with a cover for pressing and demoulding to form a blank...

Embodiment 2

[0031] Magnetic powder, calcium powder, and resin binder are configured and weighed according to 45%, 54%, and 1% of the total weight respectively. The weighed above-mentioned materials were placed in a mixer and mixed for 30 minutes to form a mixture for use.

[0032] The magnetic steel is placed in the composite magnetic block mold, and then the composite magnetic block of the above mixture is poured into the composite magnetic block mold, pressed and demolded to form a composite magnetic block blank. The blank was placed in a low-temperature oven at 50°C, dried for 8 hours and taken out for use.

[0033] Put the white amino molding resin powder in the shell mold, then press and demould to form a rectangular mahjong tile shell. The casing is placed in a mold with a cover, and the prefabricated composite magnetic block is put into the casing, and finally the green amino molding resin powder is placed in the mold with a cover for pressing and demolding to form a blank card. ...

Embodiment 3

[0036] Magnetic powder, calcium powder, and resin binder are configured and weighed according to 49%, 50%, and 1% of the total weight respectively. The weighed above-mentioned materials were placed in a blender and mixed for 25 minutes to form a mixture for use.

[0037] The high-density magnetic block is placed in the composite magnetic block mold, and then the composite magnetic block of the above-mentioned mixture is poured into the composite magnetic block mold to be pressed and demolded to form a composite magnetic block blank. The blank was placed in a low-temperature oven at 50°C, dried for 8 hours and taken out for use.

Abstract

The invention relates to double-magnetic mahjong tiles for a full-automatic mahjong machine, each of which comprises a rectangular shell, a cover plate, a high-density magnetic block and low-density magnetic blocks, wherein mahjong tile surface patterns are formed on the bottom surface of the rectangular shell; the cover plate is sealed at the opening end of the shell; the high-density magnetic block is arranged at the center point in the shell; the low-density magnetic blocks are filled around the high-density magnetic block in the shell; and the magnetic field intensity of the low-density magnetic blocks is smaller than the magnetic field intensity of the high-density magnetic block. The manufacturing method of each double-magnetic mahjong tile comprises the following manufacturing steps: (1) manufacturing a composite magnetic block; (2) punching the shell; (3) putting the preformed composite magnetic block into the shell, and sealing the shell; (4) polishing; (5) lacquering and finally forming the double-magnetic mahjong tile; and (6) packing and charging magnetism. The invention has the advantages of increasing the magnetism of mahjong tiles and improving the speed of shufflingmahjong tiles for arranging mahjong tile surfaces in a mahjong tile shuffling cylinder; meanwhile, the increase of the magnetism can not influence the close contact among the mahjong tiles, and the rotating phenomenon caused by vibration can not occur; in addition, a lower mahjong tile can suck an upper mahjong tile, and the sliding and stacking phenomena can not occur easily; and furthermore, the low-density magnetic blocks enable the consumption of melamine to be reduced, thereby reducing the cost.

Description

technical field [0001] The invention relates to a mahjong tile, in particular to a double magnetic mahjong tile for a fully automatic mahjong machine. Background technique [0002] The mahjong tiles that existing full-automatic hemp machine is used generally cast with melamine resin (melamine), and its inner core is embedded with a permanent magnet. Because the melamine material is more expensive, someone proposes an improved method to the production of mahjong tiles, such as a production method of an automatic mahjong tile with application number 200710009418.9. In the method, the mahjong tiles are made into a hollow shell, except that a high-density magnetic block is placed in the center of the bottom surface of the shell, and the empty space in the shell is filled with crushed stones, so that the melamine consumables for making the mahjong tiles can be saved. [0003] The mahjong tiles used in the mahjong machine rotate with the shuffling cylinder to produce a shuffling ...
