Description

Technical Field

[0001] This utility model relates to the field of casual game technology, and in particular to a magnetic assembly and a card-collecting wheel for use as a card-collecting wheel. Background Technology

[0002] The card-collecting wheel is an important component of a magnetic automatic mahjong machine. The shuffling mechanism of the automatic mahjong machine has belt drives that evenly distribute mahjong tiles in four directions around its perimeter. These drives transport the shuffled tiles to the card-pushing device, which then pushes the neatly stacked tiles into the storage slot. To ensure the consistency of the tiles (all facing up or down), the mahjong tiles, which contain built-in magnets, are adjusted as they enter the belt drive.

[0003] Card-collecting wheels mainly consist of a main body and magnetic materials. Existing card-collecting wheels have a plastic main body with magnets mounted on its circumference, ensuring a tight bond between the magnets and the main body. Traditionally, this is achieved using fasteners or adhesive. However, because magnets are relatively hard, drilling holes is difficult when using fasteners, while adhesive bonding is not secure enough.

[0004] For example, Chinese utility model patent application number 201920859377.0 discloses a double-magnet card-attracting wheel. This utility model uses two magnets, which have good magnetic properties, but the production cost is relatively high due to the large size of the magnets.

[0005] The technical problem to be solved by this utility model is to overcome the existing technical defects and provide a magnet assembly for a card-collecting wheel and a card-collecting wheel. The magnet assembly is used on the card-collecting wheel and also uses an iron plate frame. It is at least equivalent to the magnetism of a three-layer structure of a double magnet, but it can greatly reduce the production cost and extend the service life of the card-collecting wheel, and has high use value and benefits. Utility Model Content

[0006] This invention addresses the shortcomings of existing card-collecting wheel magnets, such as inconvenient installation, poor magnetism, short service life, and high cost, by providing a magnet assembly and a card-collecting wheel.

[0007] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0008] A magnetic assembly for a card-collecting wheel includes an iron sheet unit. The iron sheet unit comprises an iron sheet bottom and an iron sheet surrounding portion formed by bending the iron sheet bottom. The iron sheet bottom and the iron sheet surrounding portion form a magnet receiving cavity. Furthermore, the area of ​​the iron sheet bottom is larger than the area of ​​the magnet. Because the area of ​​the iron sheet bottom is larger than the area of ​​the magnet, it is easier to directly insert the magnet into the iron sheet unit, simplifying the operation. This magnetic assembly significantly enhances the magnetism.

[0009] As preferred, the bottom of the iron sheet is in turn the first edge of the iron sheet, the second edge of the iron sheet, the third edge of the iron sheet and the fourth edge of the iron sheet; the first edge of the iron sheet is equal to and parallel to the third edge of the iron sheet; the second edge of the iron sheet is parallel to and equal to the fourth edge of the iron sheet; the first included angle of the two adjacent edges of the iron sheet is a, and a is greater than or equal to 70° and less than 90°, and the second included angle of the two adjacent edges of the iron sheet is 180°-a. By setting the included angle of the bottom of the iron sheet to be between 70° and 90°, the card will not be stuck during the card sucking process of the card sucking wheel, which is beneficial to the operation of the card sucking wheel.

[0010] As preferred, the surrounding part of the iron sheet is in turn the first surrounding part, the second surrounding part, the third surrounding part and the fourth surrounding part; the first surrounding part is parallel to and equal in length to the third surrounding part; the second surrounding part is parallel to and equal in length to the fourth surrounding part; the first included angle of the two adjacent surrounding parts of the surrounding part of the iron sheet is b, and the second included angle of the two adjacent surrounding parts of the surrounding part of the iron sheet is 180°-b. By limiting the angle of the surrounding part of the iron sheet, it is beneficial to the operation of the card sucking wheel during the card sucking process of the card sucking wheel.

[0011] As preferred, the height of the first surrounding part, the second surrounding part, the third surrounding part and the fourth surrounding part is equal, and the height is 1-4mm. By limiting the height of the surrounding part, different thicknesses of magnets can be placed according to requirements. When the card sucking wheel has high demand for magnetic force, the height of the surrounding part is set to be high, so that thicker magnets can be placed. When the card sucking wheel has low demand for magnetic force, the height of the surrounding part is set to be low, so that magnets with low thickness can be placed, thereby being beneficial to controlling the overall cost.

[0012] As preferred, the thickness of the iron sheet unit is 0.5-3mm. By limiting the thickness of the iron sheet unit, on the one hand, it is beneficial to controlling the cost of the magnet assembly, and on the other hand, it is also beneficial to being applicable to different models of card sucking wheels.

[0013] In order to solve the above technical problems, the utility model also provides a kind of card sucking wheel, it includes card sucking wheel body, card sucking wheel body is set with the magnet slot for fixing magnet assembly along side direction, still the magnet assembly of the magnet slot is placed in it. Directly the magnet assembly is placed in the magnet slot, its operation is simple.

[0014] As preferred, the opposite outer edge of the magnet slot is provided with a protruding part. By the protruding part of the outer edge of the magnet slot, the magnet in the magnet assembly is fixed, so that it is more stable during the operation of the card sucking wheel.

[0015] The utility model has the following remarkable technical effects because of adopting the above technical scheme:

[0016] The magnet assembly of the utility model can directly place the magnet in the iron sheet unit, is convenient to install, can reduce cost, prolong the service life of the tile suction wheel and has high use value, and is more helpful to increase the contact area of mahjong tiles and make the mahjong tiles enter the tile suction port more smoothly without jamming.
