[0063] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0064] In the description of this invention, it should be noted that the term "on the support" is used in a general sense and should not be construed as being absolutely above the support or on the upper surface of the support. It can also be below the support or on the lower surface of the support, and does not indicate or imply that the device or element referred to must have a specific orientation.

[0065] The card sorting machine of this invention is a mahjong machine, a dominoes machine, or a poker machine; here, a mahjong machine is used as an example for explanation. Figure 1 As shown, the card sorting machine of the present invention is a sunken card sorting machine 10, including a base frame 11, a large tray 12, several lifting devices 13, and several card suction and conveying mechanisms 16. Wherein, as Figure 2As shown, the base frame 11 has a normal area 11a located on the outer side and a sunken area 11b located in the middle. The large plate 12 is disposed on the sunken area 11b of the base frame 11. The card suction and conveying mechanism 16 is also disposed on the sunken area 11b of the base frame 11 around the large plate 12. The lifting device 13 is connected to the card suction and conveying mechanism 16 around the large plate 12 and is disposed on the normal area 11a around the base frame 11. Furthermore, the normal area of ​​the base frame 11 also has a sub-sunken area 11c at the middle of each side, which is lower than the normal area from the outside to the inside. At the same time, the sub-sunken area 11c is also higher than the sunken area 11b. The lifting device 13 is disposed on the sub-sunken area 11c of the base frame 11. This causes the overall height of the large tray 12, the lifting device 13 and the card suction and conveying mechanism 16 to sink relative to the upper surface of the normal area 11a of the base frame 11, thereby reducing the height of the large tray 12, the lifting device 13 and the card suction and conveying mechanism 16 protruding relative to the upper surface of the base frame 11, which also reduces the thickness of the card sorting machine.

[0066] like Figure 3 As shown, the base frame 11 of the present invention has a sunken support 111 and a sunken base plate 112. The sunken support 111 has a normal support area 1111 located on the outer side and a sunken support area 1112 located in the middle. The sunken base plate 112 has a normal base plate area 1121 near the outer side and a sunken base plate area 1122 formed by a stepped downward slope from the outer side to the inner side. The normal base plate area 1121 is located at the normal support area 1111, and the sunken base plate area 1122 is located at the sunken support area 1112. Continuing as... Figure 3 As shown, the sunken base plate 112 has a sub-sunken base plate area 1123 at the center of each side of the normal base plate area 1121, which is lower than the normal base plate area 11 from the outside to the inside. Simultaneously, the sub-sunken base plate area 1123 is higher than the sunken base plate area 1122. That is, the sub-sunken base plate area 1123 of the sunken base plate 112 serves as the sub-sunken area of ​​the base frame 11. The support frame 111 is made of metal materials, such as an iron frame, to ensure the stability and strong load-bearing capacity of the support. The base plate 112 is made of lightweight materials such as plastic, which not only has a certain degree of stability but is also lightweight, facilitating transportation and installation.

[0067] like Figure 4As shown, the base plate 112 is composed of several small base plates spliced ​​together. Each small base plate has a normal base plate area 1121 near the outer side and a sunken base plate area 1122 formed by a stepped downward slope from the outer side to the inner side. In this example, the base plate 112 is a square flat plate formed by splicing several small base plates together. The small base plates at the four corners of the base plate 112 are corner base plates 113. The corner base plates 113 have downward-facing handle grooves 1131, which make it easy for users to hold the handle grooves 1131 when moving the card sorting machine, and avoid the slippery bottom making it difficult for users to lift the card sorting machine. The small base plates in the middle of the four sides of the base plate 112 are side center base plates 114, which together with the four corner base plates 113 form a complete base plate 112, used to support the large plate and the lifting device. A large section of the sub-sunken base plate area 1123 is formed on the side-center base plate 114 to support the power transmission mechanism of the lifting device 13, while a small section of the sub-sunken base plate area 1123 is formed on the corner base plate 113 to support the card stacking and feeding device. Of course, the shape of the base plate 112 is not fixed and can be other shapes, as long as it can serve to support the large plate and the lifting device.

[0068] In this example, such as Figure 5 As shown, the side base plate 114 and one of the adjacent corner base plates 113 are integrally formed to form an independent base plate unit 115. Each independent base plate unit 115 has a stepped depression from the outside to the inside of the normal base plate area 1121 near the outside, forming a sunken base plate area 1122 and a sub-sunken base plate area 1123. That is, the base plate 112 is spliced ​​together from several identical independent base plate units 115, for example, it is spliced ​​together from 4 identical independent base plate units 115. Of course, the number of independent base plate units 115 is not limited, as long as they can play a supporting role. Here, 4 units are used as an example for explanation.

[0069] Continue as Figure 5 As shown, the corner base plate 113 and the side of the middle side base plate 114 of the independent base plate unit 115 together form a long outer side 1151 and a long inner side 1152. The side of the corner base plate 113 forms a short outer side 1153, and the side of the middle side base plate 114 forms a short inner side 1154. The short inner side 1154 of the middle side base plate 114 of the independent base plate unit 115 and the long inner side 1152 of the corner base plate 113 of the adjacent independent base plate unit 115 are spliced ​​together to form a base plate 112. In one example, as... Figure 6 As shown, the side bottom plate 114 has a snap-fit ​​groove 1141 at the short inner side 1154, as... Figure 7As shown, the long inner side 1152 has a snap-fit ​​strip 1131 at the corner base plate 113, which snaps together the snap-fit ​​groove 1141 of the side base plate 114 with the snap-fit ​​strip 1131 of the corner base plate 113 of the adjacent independent base plate unit 115, thereby splicing together a complete base plate 112. In another example (not shown), the side base plate 114 has a snap-fit ​​strip at the short inner side 1154, and the long inner side 1152 has a snap-fit ​​groove at the corner base plate 113, which snaps together the snap-fit ​​strip of the side base plate 114 with the snap-fit ​​groove of the corner base plate 113 of the adjacent independent base plate unit 115, thereby splicing together a complete base plate 112.

[0070] In this example, the independent base plate unit 115 has grooves 116 near the connection points of the long outer side 1151, long inner side 1152, short outer side 1153, short inner side 1154, corner base plate 113, and side middle base plate 114, respectively, for engaging with the brackets 111 of the base frame 11. The grooves 116 at the connection points between the corner base plate 113 and the side middle base plate 114 of its own independent base plate unit 115, and at the snap-fit ​​connection points with the side middle base plate 114 of adjacent independent base plate units 115, each have several spaced connecting posts 117 that pass through the post holes on the brackets 111 of the base frame 11. By embedding the connecting posts 117 on the grooves 116 into the post holes on the brackets 111, the base plate 112 is fixed to the brackets 111. The independent base plate unit 115 has a long outer edge 1155 and a short outer edge 1156 that are snapped onto the bracket 111 on the long outer edge 1151 and the short outer edge 1153, respectively. After the groove of the base plate 112 is snapped onto the bracket 111, the outer sides of the bracket 111 are wrapped by the long outer edge 1151 and the short outer edge 1153 to prevent the bracket 111 from being scratched.

[0071] like Figure 8 and Figure 9As shown, the lifting device 13 of the present invention has a fixed frame 131, a lifting mechanism 132, a pushing mechanism 133 and a power transmission mechanism 134 (see patent document CN217430797U). The lower surface of the fixed frame 131 has a mounting surface 1311, which is installed in the normal support area 1111 of the sunken support. The mounting surface 1311 is at the same height as the normal base plate area 1121 of the sunken base plate 112 of the base frame 11. The lifting mechanism 132 is located on one side of the fixed frame 131, and the pushing mechanism 133 is located on the other side of the fixed frame 131 opposite to the lifting mechanism 132. The power transmission mechanism 134 is sunken on the fixed frame 131, that is, the lower surface of the power transmission mechanism 134 is sunken and extends out of the mounting surface 1311. The power transmission mechanism 134 is used to output the power for the lifting mechanism 134 to move up and down and to output the power for the pushing mechanism 133 to push horizontally. The lower surface of the power transmission mechanism 134 is located in the sub-sunken area 1123 at the side middle base plate 114 position of the sunken base plate 112 of the base frame 11.

[0072] Continue as Figure 8 and Figure 9 As shown, the card sorting machine lifting device 13 also includes a card stacking and feeding device 135 (see patent document CN217724548U). The card stacking and feeding device 135 is also recessed and installed on the side of the fixed frame 131. The lower surface of the card stacking and feeding device 135 is flush with the lower surface of the power transmission mechanism 134, so that the lower surface of the card stacking and feeding device 135 also extends out of the mounting and fixing surface 1311 and is located in the sub-sunken area 1123 at the corner bottom plate 113 position of the recessed bottom plate 112 of the base frame 11.

[0073] like Figure 10 As shown, the large disk 12 of the present invention includes a rotatable disk body 121 and a roller support ring 122 that can rotate together with the disk body. The roller support ring 122 is integrally arranged around the periphery of the disk body 121, and both the disk body 121 and the roller support ring 122 are located within the sunken bottom plate area 1122. Continuing as... Figure 3As shown, a plurality of support rollers 14 are provided on the side of the sunken support area 122. The large disk 12 is disposed on the sunken support area 1112, and the roller support ring 122 of the large disk 12 is slidably supported on the support rollers 14. The plurality of support rollers 14 are supported on the lower surface of the roller support ring 122, and during the rotation of the large disk body 121 driving the roller support ring 122, the support rollers 14 form at least two support tracks with different radii on the roller support ring 122. In this example, the track radius is the distance from the center of the large disk body 121 to any point on the support track. That is, the support rollers 14 are staggered on the lower surface of the roller support ring 122. In this way, the support rollers 14 can simultaneously support different parts of the lower surface of the roller support ring 122 from the outside to the inside, avoiding the large disk 12 from only supporting the same circumference of the roller support ring 122 during the rotation, thus making the large disk 12 highly stable.

[0074] There are four support rollers 14, and these four support rollers 14 form at least two support tracks with different radii on the lower surface of the roller support ring 122. Further, in this example, as... Figure 11 As shown, the support rollers 14 arranged in pairs opposite each other form support tracks with the same trajectory radius, and thus the four support rollers 14 form two support tracks 122a with different trajectory radii on the lower surface of the roller support ring 122 (e.g., Figure 11 The dotted line in the diagram shows the support trajectory 112a. Of course, the number of support rollers 14 is not limited, as long as at least two support trajectories with different radii can be formed on the lower surface of the roller support ring 122 to enhance the stability of the market. Here, we take four as an example for explanation.

[0075] like Figure 12 As shown, the center of the sunken support area 1112 also has a motor housing 15 connected to the inner side of the sunken base plate area 112, and the bottom center of the large plate body 121 has a card sorting machine motor 123, so the motor housing 15 can support the card sorting machine motor 123.

[0076] The present invention has been described in detail above with reference to the accompanying drawings and embodiments.
