Description

Technical Field

[0001] The utility model belongs to the technical field of entertainment equipment, mahjong machines, mahjong machines and mahjong tiles, and specifically relates to a square entertainment card and a card sorting machine. Background Art

[0002] At present, the card sorting machine in the existing technology needs to sort the block-shaped entertainment cards into stacks and then push them in front of the entertainment personnel. For example, taking the mahjong machine as an example, the working principle of the fully automatic mahjong machine is to stack the mahjong tiles and then lift them onto the table through the card pusher inside the machine body, so that the entertainment personnel can enjoy the game. The character grooves and character edges on the existing mahjong tile character surface are set vertically, that is, the characters on the mahjong tiles are composed of multiple grooves that alternately form characters, and the upper edge of the groove and the lower edge of the groove are designed to be vertical. During the entertainment process, some people habitually touch the characters on the character surface with their hands to identify the mahjong tiles. The raised parts on the grooves and character edges affect the user's feel, that is, the touch during the touch is a ridge, and long-term touch can easily cause finger fatigue, making the mahjong tiles easy to slip during the touch, and the mahjong tiles can be easily damaged if they fall on the ground.

[0003] Therefore, it is necessary to change it. Summary of the Invention

[0004] The purpose of the utility model is to provide a square entertainment card and a card sorting machine to solve the problem in the prior art that the square entertainment cards are easy to slide off.

[0005] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a square entertainment card, wherein the upper edge and the lower edge of the groove on the character surface of the square entertainment card are designed to be oblique, wherein the surface of the square entertainment card body is provided with a rough surface. The upper edge and the lower edge of the groove of the character on the existing square entertainment card are designed to be vertical, and the raised portion of the groove on the character and the edge of the character affect the user's feel, that is, the touch during the touch is a ridge. The square entertainment card of the present application has the upper edge and the lower edge of the groove on the character surface designed to be oblique, and the oblique setting of the groove on the character and the edge of the character improves the user's feel, that is, the touch during the touch is a slope.

[0006] Preferably, the character surface of the square entertainment card is provided with a sunken portion, and the rough surface is designed on the sunken portion, wherein the rough surface avoids the character design, and no sunken portion is designed on other surfaces. The rough surface improves the user's feel during the entertainment process and prevents slipping.

[0007] Preferably, the character side of the entertainment cube is provided with a sunken portion, while the other sides are not provided with sunken portions. The sunken portion is provided with a roughened surface. This allows the graphics on each entertainment cube to be neat and beautiful, or to maintain the original appearance of the entertainment cube. Some users habitually touch the character side, and the roughened character side improves the user's hand feel, while the other sides remain smooth.

[0008] Preferably, the square entertainment cards have sunken portions on the character side and on the back side opposite the character side, and the sunken portions are provided with a roughened surface. This allows for neat and aesthetically pleasing graphics on the surface of each square entertainment card, or allows the original square entertainment card to remain unchanged. Some users habitually touch the character side and the back side opposite the character side, and the roughened surface improves the user's hand feel while the other surfaces remain smooth.

[0009] Preferably, the six sides of the square entertainment card are provided with sunken parts, and the sunken parts are provided with rough surfaces. This makes the graphics on the surface of each square entertainment card neat and beautiful. Some users are accustomed to touching the square entertainment cards, and the rough surfaces improve the user's hand feeling and reduce the number of slips.

[0010] Preferably, the angle between the upper and lower edges of the character grooves is 1-80 degrees, and the angle between the upper and lower edges is 45 degrees. In this way, the angled design of the upper and lower edges of the grooves on the character surface of the square entertainment card is designed according to user needs, that is, the upper and lower edges of the grooves are provided with a slope, so that no ridges are felt during touch.

[0011] Preferably, the distance between the upper edge of the character groove and the lower edge of the groove is 0.5-3mm, and the distance between the upper edge of the groove and the lower edge of the groove is 2mm. If the groove on the square entertainment card character is too deep, it will affect the user's finger touch. It is preferably 1mm with a slope to improve the user's touch during the entertainment process.

[0012] Preferably, the rough surface has a thickness of 0.1-0-3mm, preferably 0.2mm. This avoids excessively high raised areas between the rough surfaces, which can affect user feel and hinder shuffling in the card handling machine. Since fingerprints on a finger are approximately 0.3mm thick, the rough surface depth on the diamond entertainment cards is designed to be 0.5mm, improving user feel while also preventing slippage.

[0013] Preferably, the raised portion of the characters on the square entertainment card is not designed with a rough surface. This design is based on user needs. Some users habitually touch the raised portion of the characters with their fingers to identify them. The rough surface increases friction between the fingers and improves the user's feel. This design meets the needs of some users.

[0014] Preferably, a rough surface is provided on the raised portion of the square entertainment card characters. This design is based on user needs. Some users habitually touch the raised portion of the characters with their fingers to identify them. The rough surface increases friction between the fingers and improves the user's hand feeling. This design meets the needs of some users.

[0015] Preferably, the spacing between the upper portion of the outer edge of the sunken portion and the edge of the entertainment card is 1-5 mm, and the spacing between the upper portion of the outer edge of the sunken portion and the edge of the entertainment card is 2 mm. To prevent damage to the rough surface of the entertainment card during polishing, the rough surface is sunken 0.2 mm. This reduces rough surface loss during polishing. Specifically, the 2 mm spacing between the upper portion of the outer edge of the sunken portion and the edge of the entertainment card is touched during polishing, reducing wear. This leaves a 2 mm smooth surface between the edge of the entertainment card and the sunken portion, facilitating shuffling in the card sorting machine.

[0016] Preferably, the rough surface includes a plurality of grooves arranged at intervals. The groove array is arranged on the sunken portion, so that the pattern on the surface of each square entertainment card is neat and beautiful, and the raised parts between adjacent grooves are conducive to improving the user's hand feeling and preventing slipping.

[0017] Preferably, the grooves include rectangular grooves. After the rectangular grooves are arranged in a row on the surface of the cube entertainment card body, the raised portions between adjacent rectangular grooves are designed in a grid pattern. The grid-like raised portions between adjacent grooves are conducive to improving the user's hand feel.

[0018] Preferably, the grooves include linear grooves, the raised portions between adjacent linear grooves are strip-shaped, the raised portions between adjacent linear grooves are spiral-shaped, the raised portions between adjacent linear grooves are circular, and the raised portions between adjacent linear grooves are straight or curved. The linear grooves are designed to remove fingerprints on the surface of the square entertainment card body, thereby increasing friction between the fingers and preventing slipping during entertainment.

[0019] Preferably, the grooves are 0.1-3mm deep, with a more preferred depth of 0.5mm. This prevents raised areas between adjacent grooves, which can affect the user's hand feel and hinder shuffling in the card machine. Since fingerprints are approximately 0.5mm thick on a finger, the 0.5mm groove depth on the diamond entertainment cards also prevents slippage.

[0020] Preferably, the width of the raised portions between the spacing grooves is 0.1-3 mm, preferably 0.5 mm, to avoid excessively wide raised portions between adjacent grooves, which could affect the user's feel. Since fingerprints on a finger surface are both approximately 0.5 mm thick and wide, the width between adjacent grooves on the surface of the diamond entertainment card is 0.5 mm to prevent slippage.

[0021] Preferably, the depth of the sunken portion is 0.1-3mm, preferably 0.5mm. This prevents the sunken portion from being too deep, which could affect the user's hand feel and the shuffling of the card machine. Maintaining a depth of 0.5mm between the edge of the entertainment card cube and the sunken portion facilitates shuffling the card machine while also allowing for neat placement on the table.

[0022] Preferably, a gap is left between the edge of the characters on the square entertainment card and the sunken portion. This design is convenient for users to touch, that is, the raised portion is added to the outer edge of the characters to facilitate user touch recognition and improve user feel. The existing technology is a parallel design.

[0023] Preferably, the spacing between the edge of the characters on the square entertainment card and the sunken portion is 0.1-1 mm, preferably 0.2 mm. Maintaining the spacing within 0.2 mm facilitates touch recognition and avoids excessive spacing that affects the user's touch feel, i.e., hinders finger touch. This design facilitates user touch, i.e., adding raised portions to the outer edges of the characters facilitates touch recognition and improves the user's touch feel. The existing technology uses a parallel design.

[0024] Preferably, a gap is left between the edges of the characters on the entertainment cube and the rough surface. The characters and the sunken portion are designed to sink simultaneously, leaving a gap between the outer edges of the characters and the rough surface. This facilitates user identification of the entertainment cube during touch. The outer edges of the characters are partially smooth, which improves the user's hand feel and facilitates shuffling in the card machine, while also allowing for neat placement on the table.

[0025] Preferably, the square entertainment tiles are mahjong tiles. The square entertainment tiles include a variety of square entertainment tiles. In this embodiment, mahjong tiles are used. The square entertainment tiles are manufactured according to user needs, such as square linear tiles such as Pai Gow.

[0026] The utility model provides a card sorting machine, in which the square entertainment cards of the utility model are arranged.

[0028] Preferably, the square entertainment tiles are mahjong tiles, and the mahjong tiles are placed in the mahjong machine.

[0029] Preferably, the square entertainment cards are Pai Gow, and the Pai Gow is placed in the Lipai machine.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] Existing square entertainment cards feature characters made of multiple grooves, with the upper and lower edges of the grooves perpendicular to each other. This affects the user's touch experience, creating a ridged feel. Prolonged touch can cause finger fatigue and easily cause the cards to slip. The present invention improves the design of the upper and lower grooves to be angled. The angled groove depth and raised portions of the grooves create the characters on the cards, improving the user's touch experience and preventing the cards from slipping.

[0032] The utility model provides a sunken portion on the main body of the square entertainment card, and a rough surface on the sunken portion. The rough surface is kept within 0.3mm, which improves the user's hand feeling and reduces the number of slips. Since the thickness of the fingerprint on the finger surface is about 0.3mm, the depth of the rough surface on the square entertainment card is 0.3mm. This design improves the user's hand feeling and prevents slips.

[0033] The utility model provides a sunken portion on the character surface of the square entertainment card body, and a rough surface on the sunken portion. The rough surface is kept within 0.3mm, which improves the user's hand feeling and reduces the number of slips. Since the fingerprint thickness on the finger surface is about 0.3mm, the depth of the rough surface on the square entertainment card surface is 0.3mm. This design improves the user's hand feeling and prevents slips.

[0034] The utility model provides a sunken portion on the character surface and the back surface corresponding to the character surface on the square entertainment card body. The sunken portion is also provided with a rough surface. The rough surface is maintained within 0.3mm, which improves the user's hand feeling and reduces the number of slips. Since the fingerprint on the finger surface is about 0.3mm thick, the depth of the rough surface on the square entertainment card surface is 0.3mm. This design improves the user's hand feeling and prevents slips.

[0035] The utility model provides sunken portions on the six sides of the square entertainment card body, and provides a rough surface on the sunken portions. The rough surface is kept within 0.3mm, which improves the user's hand feeling and reduces the number of slips. Since the fingerprint thickness on the finger surface is about 0.3mm, the depth of the rough surface on the square entertainment card surface is 0.3mm. This design improves the user's hand feeling and prevents slips.

[0036] The roughened surface array design of this utility model features grooves with raised areas between adjacent grooves, enhancing the user's tactile feel and reducing slippage, making it easier for users to identify the card through touch. Some users prefer to use multiple fingers for touch identification, so the 0.3mm deep and wide grooves on the card body or the character surface enhance the user's tactile feel.

[0037] The grooves of the present invention include rectangular grooves, which are designed in a row on the touch piece. The raised parts between adjacent rectangular grooves are designed in a grid shape, or the recessed parts between adjacent continuous grooves are designed in a grid shape. The grid-like raised parts or recessed parts are beneficial to improving the user's hand feel. At the same time, the user can touch and identify the square entertainment cards through the groove gaps or the groove raised parts.

[0038] The grooves of the utility model include linear grooves, the raised parts between adjacent linear grooves are strip-shaped, the raised parts between adjacent linear grooves are spiral-shaped, the raised parts between adjacent linear grooves are circular, and the raised parts between adjacent linear grooves are straight-line or curved. The linear grooves are designed on the character surface on the surface of the square entertainment card body to increase the friction between the fingers and the character surface during the entertainment process to prevent slipping.

[0049] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0050] The block entertainment cards take mahjong tiles as an example, which is convenient for those skilled in the art to understand. The card machine takes mahjong tiles as an example, which is also convenient for those skilled in the art to understand.

[0051] like Figure 1-7 As shown, a square entertainment card is provided, wherein the upper edge and lower edge of the groove on the character surface of the square entertainment card 1 are designed to be inclined at 2, and the surface of the main body of the square entertainment card 1 is provided with a rough surface 4. The upper edge and lower edge of the groove of the character on the existing square entertainment card 1 are designed to be perpendicular, and the raised portion of the groove on the character and the edge of the character affect the user's touch, that is, the touch feels like a ridge during touch. The upper edge and lower edge of the groove on the character surface of the square entertainment card 1 of the present application are designed to be inclined at 2, and the oblique arrangement of the groove on the character and the edge of the character improves the user's touch, that is, the touch feels like a slope during touch. The thickness of the rough surface 4 is preferably 0.3mm. Some users habitually use their ten fingers or thumbs to touch and identify the square entertainment card 1. The 0.3mm rough surface 4 improves the user's touch feel during touch, and the rough surface 4 increases friction between the fingers and the card, reducing the number of times the square entertainment card 1 slips. Because the surface of the square entertainment card 1 in the prior art is too smooth, it is easy to slip during play, and if it slips, it will easily cause damage to the square entertainment card 1 after it falls.

[0052] like Figure 1-7 As shown, a square entertainment card, wherein the upper edge and the lower edge of the groove on the character surface of the square entertainment card 1 are designed to be obliquely 2, that is, the character is composed of multiple oblique grooves of 2 depths and oblique groove protrusions, and the character is used for identification or entertainment. The upper edge and the lower edge of the groove of the existing square entertainment card 1 character are designed to be vertical, and the upper groove of the character and the protrusion of the character edge affect the user's feel, that is, the touch during the touch is a ridge. The upper edge and the lower edge of the groove on the character surface of the square entertainment card 1 of the present application are designed to be oblique, and the upper groove of the character and the protrusion of the character edge are set obliquely, which is used to improve the user's feel, that is, the touch during the touch is a slope.

[0053] like Figure 1-2As shown, a sunken portion 3 is provided on the character surface of the main body of the entertainment card 1, while no sunken portion 3 is provided on the other surfaces. A roughened surface 4 is provided on the sunken portion 3, and the upper and lower edges of the character grooves on the character surface are designed at an angle 2. This allows the graphics on the other surfaces of each entertainment card 1 to remain unchanged during the game. The characters on the character surface designed with the roughened surface 4 or the angled 2 are placed on the table or on the entertainment card 1, without affecting the user's enjoyment. Some users habitually touch the character surface with their fingers. The roughened surface 4 on the character surface improves the user's touch, and the angled 2 on the character grooves on the character surface further improves the user's touch. This not only improves the touch, but also facilitates user identification. The other five surfaces of the entertainment card 1 remain smooth and unchanged.

[0054] like Figure 1-2 As shown, the square entertainment tile 1 is a mahjong tile. Most existing mahjong tiles are designed using a mold molding process. A 0.5mm high / width uneven groove is set on the character surface of the mold. At the same time, an oblique design is formed between the raised portion and the root of the character on the mold. After completion, the square entertainment tile 1, i.e., the mahjong tile material, is filled into the mold and the mold is processed into the square entertainment tile 1, i.e., the mahjong tile. In this way, a certain slope is formed between the upper edge and the lower edge of the groove on the square entertainment tile 1, i.e., the mahjong tile. After completion, a rough surface 4 is set on the square entertainment tile 1. In this way, the square entertainment tile 1, i.e., the mahjong tile, is integrally formed with the rough surface 4 and the oblique design 2 on the character. Mahjong tile processing is a prior art technique. Reference is made to a mahjong tile manufacturing method, patent number CN200410006026.3, or to a prior art mahjong tile processing paper, in which the mold is improved, an uneven groove with a height / width of 0.5mm is designed on the character surface of the mold, and an oblique design is formed between the raised portion and the root of the character on the mold. This is the technique of this application.

[0055] like Figure 1-2 As shown, the upper and lower edges of the grooves on the character surface of the square entertainment card 1 are designed to be oblique, that is, the character is composed of multiple oblique grooves of 2 depths and 2 oblique groove protrusions, and the character is used for identification or entertainment. Existing square entertainment card characters have vertical upper and lower groove edges, and the upper grooves and character edge protrusions affect the user's touch, that is, the touch during touch feels like a ridge, which is not conducive to finger touch. The upper and lower edges of the grooves on the character surface of the square entertainment card 1 of the present application are designed to be oblique by 2, and the upper grooves and character edge protrusions are set at an oblique angle by 2, which is used to improve the user's touch, that is, the touch during touch feels like a slope.

[0056] like Figure 1 and Figure 8As shown, the angle 2 between the upper and lower edges of the groove on the character surface of the entertainment card 1 is 1-80 degrees, with the preferred angle 2 being 45 degrees. This allows the angle 2 between the upper and lower edges of the groove on the character surface of the entertainment card 1 to be controlled within a predetermined range, designed according to user needs. The slope of the upper and lower edges of the groove ensures that no ridges are felt during touch.

[0057] Continue as Figure 1 and Figure 8 As shown, the distance between the upper edge of the groove on the character of Square Entertainment Card 1 and the lower edge of the groove is 0.5-3mm, and the distance between the upper edge of the groove and the lower edge of the groove is 2mm. If the groove on the character of Square Entertainment Card is too deep, it will affect the touch of the user's fingers. It is preferably 1mm and has a slope to improve the user's feel during the entertainment process. During the entertainment process, some people habitually touch the characters on the character surface with their hands to identify Square Entertainment Card 1. The groove on the character and the raised part on the edge of the character affect the user's feel, that is, the touch during the touch is a ridge. Prolonged touch can easily cause finger fatigue, making it easy for the mahjong tiles to slip during the touch, and the mahjong tiles can be easily damaged if they fall on the ground. The grooves on the upper edge and the lower edge of the groove on the character surface of Square Entertainment Card 1 are designed to be inclined 2, and the touch during the touch is a slope, which improves the user's touch feel during the entertainment process.

[0058] Not shown, the surface of the square entertainment card 1 has two oblique grooves designed on the character surface. The square entertainment card 1 is a mahjong tile, and the characters on the mahjong tile are produced using a patterned mold. While the existing mold has a vertical design between the raised portion and the base of the character, the improved mold in this application has an oblique design between the raised portion and the base of the character. After completion, the square entertainment card 1, or mahjong tile material, is filled into the mold, and the mold is processed into the square entertainment card 1, or mahjong tile, so that a certain slope is formed between the upper and lower edges of the grooves on the square entertainment card 1, or mahjong tile.

[0059] Existing mahjong tiles have multiple grooves with vertical upper and lower edges, which affect the user's touch experience. This creates a ridged feel during touch, which can cause finger fatigue and easily cause the tiles to slip. The present invention improves the upper and lower groove edges to an oblique design. The oblique groove depth and raised portions of the grooves create the tile characters, improving the user's touch experience and preventing the tiles from slipping.

[0060] like Figure 5-6As shown, a square entertainment card 1 has a sunken portion 3 on its character surface and on its back surface opposite the character surface, and a roughened surface 4 on its sunken portion 3. The upper and lower edges of the character grooves on the character surface of the square entertainment card 1 are designed to be obliquely 2 degrees, i.e., the character is composed of multiple oblique grooves with a depth of 2 degrees and two oblique groove protrusions. The character is used for identification or entertainment. Considering the needs of some users, i.e., users habitually touch the character surface and the corresponding back surface with their fingers, a roughened surface 4 is provided on the character surface of the square entertainment card 1 and on its back surface opposite the character surface. Furthermore, the upper and lower edges of the grooves on the character surface of the square entertainment card 1 are designed to be obliquely 2 degrees, i.e., the character is composed of multiple oblique grooves with a depth of 2 degrees and two oblique groove protrusions. This improves the feel during entertainment. Thus, the graphics on each square entertainment card 1 are neat and beautiful, or the graphics on the character surface and the corresponding surface of each square entertainment card 1 are overall beautiful, while the other four surfaces remain smooth or unchanged. Some users habitually touch the character surface and the back surface corresponding to the character surface. The rough surface 4 increases the friction between the fingers. The upper edge of the groove and the lower edge of the groove on the character surface of the square entertainment card 1 are designed to be oblique 2, or the character is composed of multiple oblique 2 groove depths and oblique 2 groove protrusions. The characters improve the user's feel and reduce the number of slips, reducing the damage of the square entertainment card 1 caused by falling.

[0061] Continue as Figure 5-6 As shown, the square entertainment tile 1 is a mahjong tile. Most existing mahjong tiles are molded with a design that provides uneven grooves with a height / width of 0.5 mm on the character surface and the corresponding back surface of the mold. At the same time, a diagonal design is formed between the raised portion and the root of the character on the mold. After completion, the square entertainment tile 1, i.e., the mahjong tile material, is filled into the mold, and the mold is processed into the square entertainment tile 1, i.e., the mahjong tile. This creates a certain slope between the upper and lower edges of the groove on the square entertainment tile 1, i.e., the mahjong tile. After completion, a rough surface 4 is provided on the square entertainment tile 1. In this way, the square entertainment tile 1, i.e., the mahjong tile, is integrally formed with the rough surface 4 and the diagonal design 2 on the character. Mahjong tile processing is prior art. Reference is made to a mahjong tile manufacturing method, patent number CN200410006026.3, or to prior art mahjong tile processing papers, in which the mold is improved to provide uneven grooves with a height / width of 0.5 mm on the character surface, and a diagonal design is formed between the raised portion and the root of the character on the mold. This is the technology of this application.

[0062] like Figure 6-7As shown, the six sides of the entertainment card 1 are provided with sunken portions 3, and the sunken portions 3 are provided with roughened surfaces 4. The upper and lower edges of the character grooves on the character side of the entertainment card 1 are designed to be inclined at an angle of 2 degrees. That is, the characters are composed of multiple oblique groove depths of 2 degrees and oblique groove protrusions of 2 degrees. These characters are used for identification or entertainment. This results in neat and beautiful graphics on the surface of each entertainment card 1. Some users habitually touch multiple surfaces of the entertainment card 1. The roughened surfaces 4 improve the user's hand feel during play, increase friction between the fingers and the entertainment card 1, prevent slipping, reduce the number of slips on the entertainment card 1, and thus reduce the number of damage to the entertainment card 1.

[0063] like Figure 1-7 As shown, the thickness of the rough surface 4 is 0.1-0-3mm, preferably 0.2mm. This avoids excessively high raised areas between the rough surfaces 4, which can affect the user's hand feel and hinder shuffling in the card handling machine. Since fingerprints on a finger surface are approximately 0.3mm thick, the depth of the rough surface 4 on the surface of the Diamond Entertainment Cards 1 is designed to be 0.5mm, improving the user's hand feel while also preventing slippage.

[0064] like Figure 1-7 As shown, the rough surface 4 is an array-designed groove, and the grooves include rectangular grooves. The rectangular groove array is designed on the sinking part 3, and the raised parts between adjacent rectangular grooves are grid-shaped or the recessed parts between adjacent rectangular grooves are grid-shaped. The grid-shaped raised parts or recessed parts between adjacent grooves improve the user's hand feeling. The thickness of the rough surface 4 is preferably 0.3mm. Some users habitually use their ten fingers or thumbs to touch and identify the square entertainment card 1. During the touch process, the 0.3mm rough surface 4 improves the user's touch feel. The rough surface 4 increases the friction between the fingers and reduces the number of times the square entertainment card 1 slips. Because the surface of the square entertainment card 1 in the prior art is too smooth, it is easy to slip during the entertainment process, and it is easy to cause the square entertainment card 1 to be damaged after it falls.

[0065] Continue as Figure 1-7 As shown, the depth of the groove is 0.1~3mm, preferably 0.3mm. Avoid the raised parts between adjacent grooves being too high, which affects the user's feel and is not conducive to the shuffling of the card machine. Since the thickness of the fingerprint on the finger surface is about 0.3mm, the depth of the groove on the surface of the diamond entertainment card 1 is designed to be 0.3mm. This design reduces the number of times the diamond entertainment card 1 slips. The width of the raised parts between the grooves is 0.1~3mm, preferably 0.3mm. This design avoids the raised parts between adjacent grooves being too wide, which affects the user's feel during the entertainment process. Since the thickness and width of the fingerprint on the finger surface are both about 0.3mm, the width between adjacent grooves on the character surface of the diamond entertainment card 1 is 0.3mm. This design reduces the number of slips and reduces the damage caused by falling.

[0066] Continue as Figure 1-7As shown, the rough surface 4 includes a plurality of grooves spaced apart. An array of grooves is arranged on the sunken portion, resulting in a neat and aesthetically pleasing pattern on the surface of each card. The raised portions between adjacent grooves enhance the user's feel and prevent slipping. The grooves include rectangular grooves. After the rectangular grooves are arranged in an array on the surface of the card body, the raised portions between adjacent rectangular grooves are arranged in a grid pattern. The grid-like raised portions between adjacent grooves enhance the user's feel. The grooves include linear grooves, wherein the raised portions between adjacent linear grooves are strip-shaped, spiral-shaped, circular, or straight or curved. The linear grooves are designed on the surface of the card body to prevent fingerprints from being left on the card, increasing friction between the finger and the card during play to prevent slipping. The groove depth ranges from 0.1 to 3 mm, with a preferred depth of 0.5 mm to prevent raised portions between adjacent grooves from being too high, which could affect the user's feel and hinder shuffling in the card sorting machine. Since the thickness of fingerprints on the finger surface is about 0.5mm, the depth of the grooves on the surface of the diamond entertainment cards is designed to be 0.5mm to prevent slipping.

[0067] Continue as Figure 1-7 As shown, the grooves do not include rectangular or linear grooves, but also include point-shaped geometric shapes, such as any one of a cube, a cuboid, a cylinder, a cone, a truncated cone, a prism, a sphere, a pyramid, and a polyhedron. The groove depth is controlled between 0.1 and 3 mm, and the protrusions of adjacent geometric grooves are also controlled between 0.1 and 3 mm, preferably 0.3 mm. Different geometric grooves are designed according to user needs. In this way, the grooves on the surface of the square entertainment card 1 are diversified, or the patterns formed on the protrusions between adjacent grooves are diversified. During the building process, the upper and lower square entertainment cards 1 are neatly arranged to avoid unevenness after the building.

[0068] like Figure 3-4As shown, the rough surface 4 is designed on the character surface and the corresponding back surface of the square entertainment card 1, and the rough surface 4 is designed on the other four surfaces. The rough surfaces 4 on the four surfaces are strip grooves. The strip grooves are vertically arranged on the four surfaces, and the strip grooves are designed perpendicular to the character surface and the corresponding back surface. This design facilitates the demolding of the square entertainment card in the later stage. The square entertainment card 1 is a mahjong tile. Most existing mahjong tiles are molded. A 0.5mm high / width uneven groove is set on the character surface and the corresponding back surface in the mold. At the same time, the convex part and the root of the character on the mold are designed to be oblique. Then, strip grooves are designed at intervals on the other four surfaces of the sub-mold. After completion, the square entertainment card 1, i.e., mahjong tile material, is filled into the mold. The mold is processed into the square entertainment card 1, i.e., mahjong tile. In this way, a certain slope is formed between the upper edge and the lower edge of the groove on the square entertainment card 1, i.e., mahjong tile. After completion, the rough surface 4 is set on the square entertainment card 1, and the strip grooves are designed on the four surfaces. The square entertainment tile 1, or mahjong tile, is thus integrally formed with the rough surface 4 and the oblique grooves 2 and vertical grooves on the characters. Mahjong tile processing is known in the art, as can be seen in a prior art mahjong tile manufacturing method, patent number CN200410006026.3, or in a prior art mahjong tile processing paper. The present application describes an improved mold, wherein the character surface of the mold is designed with uneven grooves 0.5 mm in height and width, an oblique design between the raised portion and the base of the character, and strip grooves on all four sides.

[0069] Not shown in the figure, in another case, the rough surface 4 is directly designed on the body of the square entertainment card 1, or is directly set on the character surface of the square entertainment card 1, designed on the character plus the corresponding back surface, and designed on six surfaces. This design can also achieve the purpose of improving the feel, and can be customized according to user needs. At the same time, the upper edge of the groove on the character and the lower edge of the groove are improved to an oblique 2 design. The groove depth and the groove protrusion set at the oblique 2 constitute the square entertainment card character, which improves the user's feel during touch and reduces the number of times the square entertainment card slips. There is a gap between the rough surface 4 and the outer edge of the square entertainment card 1, preferably a 2mm gap, and the rough surface 4 is not designed on this gap 5. In the process of designing the rough surface 4, avoid leaving a gap 5 between the rough surface 4 on the square entertainment card 1 and the outer edge of the square entertainment card 1. Mahjong tiles are typically molded using a mold. A 0.5mm high / wide uneven groove is provided within the mold. A gap of 4 mm is left between the rough surface 4 on the tile and the outer edge of the tile, leaving no uneven groove. The tile material is then filled into the mold. After the mold is formed into the tiles, the rough surface 4 is placed on the tile, leaving a gap of 4 mm between the outer edge and the rough surface 4, leaving a smooth surface. Mahjong tile processing is currently available. For information on Mahjong tile processing, refer to Baidu.

[0070] like Figure 1-7As shown, the spacing between the upper outer edge of the sunken portion 3 and the outer edge of the entertainment card is 1-5mm, and the spacing between the upper outer edge of the sunken portion 3 and the edge of the entertainment card 1 is 2mm. To prevent damage to the rough surface 4 of the entertainment card 1 during polishing, the rough surface 4 is sunken 0.2mm. This reduces wear and tear during polishing. Specifically, the 2mm spacing between the upper outer edge of the sunken portion 3 and the edge of the entertainment card 1 is touched during polishing, minimizing wear and tear. A 2mm smooth surface is left between the edge of the entertainment card 1 and the sunken portion, facilitating shuffling in the card sorting machine.

[0071] Continue as Figure 1-7 As shown, the square entertainment tiles 1, i.e., mahjong tiles, need to be polished after demolding. During the polishing process, the square entertainment tiles 1, i.e., mahjong tiles, may collide with each other, which can easily cause damage to the rough surface 4. The rough surface is designed on the sunken portion 3, and the depth of the sunken portion is 0.1-3mm, preferably 0.5mm. The rough surface 4 is not easily damaged during the polishing process after sinking. That is, during the polishing process, a 2mm smooth surface is left between the edge of the square entertainment tiles 1 and the sunken portion to prevent collision, thereby reducing damage to the rough surface 4 on the mahjong tiles.

[0072] Continue as Figure 1-7 As shown, the rough surface 2 is designed on the sinking part 3, and the sinking part 3 is designed on the surface of the cube entertainment card 1 body. The depth of the sinking part 3 is 0.1-3mm, preferably 0.5mm. Avoid the sinking part 3 being too deep to affect the user's feel and affect the shuffling of the card processing machine. The depth between the edge of the cube entertainment card 1 and the sinking part is maintained at 0.5mm, which is conducive to the shuffling of the card processing machine, and can also be neatly placed on the desktop. The rough surface 4 is easy to generate resistance during the friction with the card processing machine. After the rough surface 4 is sunken, it does not rub against the card processing machine. What rubs against the card processing machine is the 2mm smooth surface left between the edge of the cube entertainment card 1 and the sinking part, which reduces the friction resistance between the mahjong tiles and the card processing machine.

[0073] Continue as Figure 1-7 As shown, a rough surface 4 is designed on the main body of the square entertainment tile 1, with a 2mm smooth surface remaining between the edge of the square entertainment tile 1 and the sunken portion. In other words, the rough surface 4 is not designed on the 2mm smooth surface between the edge of the square entertainment tile 1 and the sunken portion. The rough surface 4 is designed to avoid the 2mm smooth surface between the edge of the square entertainment tile 1 and the sunken portion. Square entertainment tiles 1, or mahjong tiles, are generally formed using a mold, with a 0.5mm high / wide uneven groove provided in the mold. The 2mm smooth surface between the edge of the square entertainment tile 1 and the sunken portion is not designed. After this is completed, the square entertainment tile 1, or mahjong tile material, is filled into the mold. After the mold is formed into square entertainment tiles, the rough surface 4 is provided on the square entertainment tile 1, with a 2mm smooth surface remaining between the edge of the square entertainment tile 1 and the sunken portion. Mahjong tile processing is based on existing technology. Please refer to Baidu for information on mahjong tile processing.

[0074] like Figure 1-7As shown, a spacing 5 is left between the edge of the characters on the square entertainment card 1 and the sunken part 3. This design is convenient for users to touch, that is, a raised portion is added to the outer edge of the characters, which is convenient for users to touch and identify, and improves the user's hand feeling. The existing technology is a parallel design. The spacing between the edge of the characters on the square entertainment card 1 and the sunken part 3 is 0.1-1mm, preferably 0.2mm. The spacing 4 is kept between 0.2mm to facilitate touch identification, and avoid the spacing 4 being too wide, which affects the user's hand feeling, that is, affects the finger touch. This design is convenient for users to touch, that is, a raised portion is added to the outer edge of the characters, which is convenient for users to touch and identify, and improves the user's hand feeling. The existing technology is a parallel design.

[0075] like Figure 8 and Figure 9 As shown, the distance between the upper edge of the groove on the character of the square entertainment card 1 and the lower edge of the groove is 0.5-3mm, and the distance between the upper edge of the groove and the lower edge of the groove is 2mm. The groove on the character of the square entertainment card is too deep, which affects the touch of the user's finger 6. It is preferably 1mm and has a slope to improve the user's feel during the entertainment process. During the entertainment process, some people habitually touch the characters on the character surface with their hands 6 to identify the square entertainment card 1. The groove on the character and the raised part on the edge of the character affect the user's feel, that is, the touch during the touch is a ridge. Long-term touch can easily cause the finger 6 to feel sleepy, making it easy for the mahjong tile to slip during the touch, and the mahjong tile can be easily damaged if it falls on the ground. The groove on the upper edge and the lower edge of the groove on the character surface of the square entertainment card 1 are designed to be inclined 2, so that the touch of the finger 6 during the touch is slope 2, and the slope improves the sense of entertainment.

[0076] Not shown, the surface of the square entertainment card 1 has an oblique groove 2 designed for the character surface. The square entertainment card 1 is a mahjong tile, and the characters on the mahjong tile are produced using a patterned mold. While conventional molds have a vertical design between the raised portion and the base of the characters, the improved mold in this application features an oblique design between the raised portion and the base of the characters. After completion, the square entertainment card 1, or mahjong tile material, is filled into the mold, and the mold is processed into the square entertainment card 1, or mahjong tile. This creates a slope between the upper and lower edges of the groove on the square entertainment card 1, or mahjong tile.

[0077] Figure 8 and Figure 9 As shown, a card sorting machine is shown. The card sorting machine is exemplified by a mahjong machine, and the square entertainment cards 5 are exemplified by mahjong tiles. The square entertainment cards 1, i.e., mahjong tiles, are placed into the mahjong machine. The mahjong tiles are neatly arranged on the tabletop. The user touches the character surface of the mahjong tile with a finger 6, i.e., the finger touches the groove on the character to identify the tile. During the touching process, there is a slope between the finger and the groove, i.e., the groove on the character touches the raised part of the character edge, which improves the user's touch feeling. i.e., the tactile sensation during the touching process is a slope, which enhances the sense of entertainment.

[0078] Not shown is a card sorting machine, which uses mahjong tiles as an example and the square entertainment tiles 1 as an example. The square entertainment tiles 1, i.e., mahjong tiles, are placed into the mahjong machine. The mahjong machine shuffles the tiles and then transports them to the table for playing. During the playing process, fingers touching the rough surface 4 improve the hand feeling, reduce the number of mahjong tiles falling, and thus reduce damage to the mahjong tiles.

[0079] After the mahjong machine shuffles the tiles, the tiles can be neatly placed on the tabletop because the rough surface 4 on the tiles is arranged in a 0.3mm pattern or with grooves in an array. Some users habitually use their thumb and finger to identify the square entertainment tiles. This 0.3mm rough surface 4 improves the user's hand feel and reduces the number of slips. Because the grooves on the surface of the square entertainment tiles 1, i.e., the tiles, are arranged in an array, they are not uneven and can be neatly placed on the tabletop. The 0.3mm gap between adjacent grooves on the tiles enhances the user's hand feel, i.e., the friction between the hand and the tiles, reducing the number of slips and damage to the tiles.

[0080] Not shown is a card sorting machine, specifically a Pai Gow machine. Pai Gow is a Chinese folk game using wooden and bone playing cards, a card-based entertainment. Therefore, Pai Gow is more varied and engaging to play than dice. Pai Gow evolved from dice, but its composition is far more complex. For example, two sixes form a "sky card," two onees form a "second card," and one six and one five form a "tiger head." Both push and play Pai Gow, popular during the Ming and Qing dynasties, were highly engaging games. Mahjong is the most popular form of domino tile. Pai Gow and mahjong tiles, both block-shaped, feature grooves on the surface to enhance the player's hand's grip, creating friction between the tiles and preventing them from slipping or dropping.

[0081] Existing mahjong tiles have multiple grooves with vertical upper and lower edges, which affect the user's touch experience. This creates a ridged feel during touch, which can cause finger fatigue and easily cause the tiles to slip. The present invention improves the upper and lower groove edges to an oblique design. The oblique groove depth and raised portions of the grooves create the tile characters, improving the user's touch experience and preventing the tiles from slipping.

[0082] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
