Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a mahjong tile polishing device.

[Conventional technology]

Generally, cleaning work to remove dirt such as hand oil on mahjong tiles for business use is by gathering the required number of mahjong tiles in one corner of the table and placing them side by side, and cleaning each side of these tiles. Each item was cleaned by wiping them one after another with a cleaning cloth, and this manual work took a considerable amount of time and was extremely troublesome.

Recently, as shown in Figures 6 and 7,
A hexagonal cylindrical one-piece polishing machine that is capable of opening, closing, and engaging the cover plate part 1a of the side plate part, and rotatable at a low speed about the pivot shafts 2, 2 of both end face parts 1b, 1b. A drum 1 is provided, and the polishing drum 1 is lined with an abrasive cloth 3, and several strip-shaped abrasive cloths 4 are also prepared.
When cleaning and polishing a group, all mahjong tiles 5 and several polishing cloths 4 are stored in this polishing drum 1, and in this state, the polishing drum 1 is rotated.
A device is used which cleans and polishes the mahjong tiles 5 by stirring and mixing them.

[Problem that the invention attempts to solve]

However, in such a conventional mahjong tile polishing device, mahjong tiles 5 each having a solid shape are housed in the polishing drum 1.
Naturally, there is a large difference in specific gravity between the group and each of the soft strip-shaped abrasive cloths 4, so even if an attempt is made to apply a stirring action to them as the polishing drum 1 rotates, each of the lighter abrasive cloths 4 It becomes difficult for the mahjong tiles to get mixed into the five groups of mahjong tiles, causing defects in cleaning and polishing.In addition, unlike other known prior art techniques, a rotating shaft is installed in the polishing drum and the polishing cloth is supported on this shaft. However, there is a limit to polishing due to the poor efficiency of the rotation of these tiles and the contact with the group of mahjong tiles rolling at the bottom of the polishing drum. In addition, since the lining abrasive cloth 3 inside the abrasive drum 1 is fixed, it cannot be removed for washing or replacement after polishing work, and dirt gradually accumulates, which again causes poor polishing. It had the following problems.

[Means for solving problems]

Therefore, the purpose of this invention is to propose a mahjong tile polishing device that can improve the problems of the conventional device and polish groups of mahjong tiles appropriately, effectively, and quickly. In order to achieve this purpose, this invention has a rectangular cylindrical shape with a part of the side plate part that can be freely opened and closed, and the polishing drum can be lowered around pivots provided on both end faces. This polishing drum is pivoted so that it can rotate at high speed.
A mahjong tile in which a lining polishing cloth is stretched on the inner surface of each side plate part including the lid plate part and each end face part, and a plurality of strip-shaped polishing cloths are interposed within a group of mahjong tiles. In the polishing device, the inner polishing cloth is removably attached via a retaining piece, and the polishing cloth is radially parallel to the rotating direction with respect to the outer peripheral surface of the hollow shaft rod. A polishing cloth member is constructed by being fixed to the mahjong tiles and given an appropriate weight, and this polishing cloth member is housed in the polishing drum together with a group of mahjong tiles.

[Effect]

That is, in this invention, a group of mahjong tiles and an abrasive cloth member to which abrasive cloth is fixed radially and given an appropriate weight are housed in a polishing drum lined with abrasive cloth, and this polishing drum is rotated. By operating the mahjong tiles, the groups of mahjong tiles can be properly and effectively cleaned and polished with each polishing cloth, and each polishing cloth can be easily washed and replaced.
