[0041] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0042] Such as Figures 1 to 14The shuffling machine of this embodiment consists of two parts. One part is the main body, and the other part is the door body, in which various configuration devices are arranged.

[0043] The main body includes a main body housing and a main body skeleton. The main body housing wraps around the main body skeleton, specifically including: a main body front frame, a main body front upper frame, a main body middle frame, a main body rear plate, and a main body bottom plate;

[0044] The main body rear plate is provided with several heat dissipation holes. Four casters are provided at the four corners of the main body bottom plate. On the upper parts of both sides of the main body middle frame, a main body handle is provided on each side, which is used to conveniently hold the main body handle with both hands to move the washing machine; A door body is provided in the center of the main body front frame. A flip door corresponding to the drawer is provided at the lower part of the door body. A door handle is provided on the outer side of the flip door, which is used to open and close the flip door.

[0045] Inside the main body front upper frame, a PCB control board is provided. A control panel shell is provided in the center. A control panel lens is covered outside the control panel shell. The inner side of the control panel lens is connected to the control buttons of the PCB control board one by one. Touch buttons marked with different commands are provided on the outside. By touching each button, the shuffling machine is controlled to perform the shuffling operation. The touch buttons include: power on / off, run / pause, quick wash (white light), fine wash (white light), self-cleaning, etc. The control of the shuffling machine is realized by programming corresponding commands through the PCB control board.

[0046] The main body skeleton is arranged close to the main body rear plate. A drawer is provided at the lower part. A motor module is provided on one side of the drawer. The main body skeleton is used to fix the drum device. Therefore, a tripod structure is provided on both sides to prevent the main body skeleton from tilting forward. The drum device is connected to the motor module through belt drive to provide rotational power for the drum device.

[0047] The specific structure of the drum device includes: a drum bearing support plate fixed on the main body skeleton, a drum bearing fixing part is fixedly installed on the drum bearing support plate, two groups of first bearings are sleeved inside the drum bearing fixing part, a drum rotating shaft is inserted into the two groups of first bearings, and the outer sides are assembled together through bearing pressing parts. A drum pulley is fixed at the rear end of the drum rotating shaft. A drum chassis and a nylon wire brush roller are fixed at the front end of the drum rotating shaft. The drum includes a drum inner shell and a drum outer shell. The drum inner shell and the drum outer shell are fixed together on the drum chassis. When assembling, the drum inner shell and the drum outer shell are installed first, and then the nylon wire brush roller is installed.

[0048] The drum housing of this application is made of PC material (polycarbonate) by thermoforming process or similar materials, and the inner layer of the drum is made of OPE material (oxidized polyethylene wax) by high-temperature forming process or similar materials, which greatly reduces the noise during drum shuffling. Moreover, we also fix a layer of cotton cloth inside the inner shell of the drum or cover the inner wall of the drum with nylon filaments. This not only reduces the noise but also prevents the mahjong tiles from being scratched when contacting the inner wall of the drum during shuffling. The material of the nylon filament brush roller is more suitable for cleaning mahjong tiles compared to other brushes and will not scratch the mahjong tiles.

[0049] The way the inner drum shell and the outer drum shell are fixed on the drum chassis is to set two concentric circles of bolt through-holes at corresponding positions for bolt locking and fixation, and set two middle circles of ventilation holes to facilitate the discharge of moisture. The inner drum shell and the outer drum shell are provided with three groups of evenly arranged first arc-shaped protrusions, and two groups of second arc-shaped protrusions are evenly arranged between every two groups of the first arc-shaped protrusions. The arc-shaped protrusions facilitate the rotation of the cards together with the drum during rotation, so that the cards are more likely to flip randomly inside the drum, and thus contact the nylon filament brush roller to be cleaned.

[0050] A transmission component is provided between the motor module and the drum component of this application, and power transmission is carried out through the transmission of a transmission wheel and a belt. Since a very high rotation speed is not required when cleaning the mahjong machine, it is necessary to convert the high rotation speed output by the motor into a slow rotation speed suitable for the mahjong cleaning machine. The transmission component of this application includes a double-layer pulley and a transmission bearing component. The transmission bearing component includes a transmission bearing support plate fixed on the main body framework. A transmission bearing fixing part is fixed on the transmission bearing support plate. Two groups of second bearings are sleeved inside the transmission bearing fixing part, and a matching rotation connection pin is inserted into the two groups of second bearings. The rear end of the rotation connection pin is fixed with a double-layer pulley. The double-layer pulley and the drum pulley are connected by a second belt. A transmission anti-rotation plate is provided at the front end of the transmission bearing fixing part. They are provided with corresponding first bolt holes, and the transmission bearing support plate is fixed between them and sandwiched between them. The transmission bearing support plate is provided with second bolt holes corresponding to the first bolt holes, and the diameter of the second bolt holes is larger than that of the first bolt holes. Anti-rotation pin positioning parts are provided on two adjacent sides of the transmission bearing support plate. By setting an anti-rotation screw pin to pull the bolts penetrating the transmission bearing fixing part and the transmission anti-rotation plate, the position of the double-layer pulley is finely adjusted, thereby adjusting the tightness of the belt. This setting, first, facilitates the tightness adjustment of the pulley after the debugging and installation are completed, and second, facilitates the appropriate tightening when the belt becomes loose and slips later, making the later maintenance and repair more convenient.

[0051] A motor pulley is provided at the rear end of the motor module. The motor pulley and the double-layer pulley are connected by a first belt drive. In this application, based on the motor output power and the drum size, the rotational speed ratio of the motor pulley to the double-layer pulley is 6:1, and the rotational speed ratio of the double-layer pulley to the drum pulley is 6:1. Through the conversion of rotational speed, the power of the motor does not need to be configured very high to drive the rotation of the drum, while saving energy consumption.

[0052] The door body structure is a very important structure in this application, including: a door upper shell, which is a frame structure. A door viewing window lens is provided in front of the door upper shell, a cleaning liquid box, a water pump with a nozzle, a hot air module, and a lighting lamp board are provided in the middle, and a door back board and a door inner viewing window lens are provided at the back.

[0053] The door inner viewing window lens is arranged at the upper part of the door back board. The door viewing window lens is provided with a viewing window of the same size as the door inner viewing window lens for observing the cleaning process inside the shuffling machine drum.

[0054] A cleaning liquid observation window is provided at the position corresponding to the cleaning liquid box on the door viewing window lens for observing the remaining amount of the cleaning liquid. One end of the water pump with a nozzle is communicated with the bottom of the cleaning liquid box, and the other end is provided with a nozzle at the position above the cleaning liquid box. A nozzle hole is provided at the corresponding position on the door back board. A lamp hole is provided at the position corresponding to the lighting lamp board on the door back board. The air outlet of the hot air module is arranged at the corresponding position on the door back board. The hot air module provides hot air to dry the cards. The water pump sprays the cleaning liquid onto the cards for dry cleaning of the cards. Compared with wet cleaning, the cleaning is cleaner and the cleaning efficiency is high.

[0055] One side of the door upper shell is movably connected to the front frame of the main body through a door hinge, and a door lock catch is provided at the other end for opening and closing the door body. The door body of this application is circular, and the designed size is the same as or close to the diameter of the inner shell of the drum, which is convenient for opening the door to take the cleaned cards or put in the cards. The door body can also be designed as a square or a cuboid, but it should be larger than the end face of the inner shell of the drum to facilitate taking and putting cards. A Hall induction magnet is provided on the front frame of the main body, and a Hall plate is provided at the corresponding position on the door upper shell. The Hall plate is connected to the PCB control board. Through program setting, when the closing of the door is not sensed, the shuffling machine does not work, and when the door is suddenly closed, the shuffling machine stops working, thereby improving the safety of equipment use.

[0056] The hot air module, the water pump, the lighting lamp board, and the motor module are connected to the PCB control board.

[0057] Usage process: Open the door body and put the mahjong tiles to be cleaned, for example, into the drum. The ratio of the outer diameter of the nylon wire brush roller to the inner diameter of the drum inner shell can be designed by yourself. For example, it is designed as 2:3. Then, combined with different rotation speeds, different ratios of the outer diameter of the nylon wire brush roller to the inner diameter of the drum inner shell plus appropriate rotation speeds can drive the mahjong tiles to be evenly distributed in the drum, making the mahjong tiles fully contact with the nylon wire brush roller and the inner wall of the drum, testing the cleaning effect of the mahjong tiles, so as to play a good cleaning role. During the cleaning process, cleaning liquid can be sprayed. After cleaning for a certain time and the tile surface is clean, then dry the cleaning liquid. Finally, obtain clean mahjong tiles. Then pull out the drawer, put the mahjong tiles into the drawer, carry them to the mahjong machine and pour them into the mahjong machine. Then take a pair of mahjong tiles to be washed, put them into the drawer, bring them to the side of the shuffling machine, pour them into the shuffling machine for cleaning.

[0058] The shuffling machine of the present application can not only clean mahjong tiles, but also clean other types of cards similar to mahjong tiles, such as: Chinese chess, Go, chess, gobang, checkers, international draughts, military chess, etc. Compared with the wet shuffling machines currently on the market, the present application has the following advantages:

[0059] 1. Cooperating with the cleaning liquid, dry cleaning is cleaner and the cleaning time is short;

[0060] 2. The hot air module provides a drying function. Through the blowing of the hot air module and combined with the rotation of the drum, the gas in the drum is made to flow, which is convenient for quick drying. There are ventilation holes on the back of the drum to facilitate the discharge of moisture and can dry more efficiently;

[0061] 3. The hot air module, water pump, and lighting panel are arranged in the door body, which is convenient for installation and later maintenance;

[0062] 4. The transmission component has a conversion of the speed ratio, which is convenient for a small-power motor to drive the drum, reducing energy consumption;

[0063] 5. The drum outer shell, drum inner shell, nylon wire brush roller, and another layer fixed on the drum inner shell are all composed of soft materials, greatly reducing noise and scratching damage to the cards;

[0064] 6. There is a drawer at the bottom, increasing the storage function of the device.

[0065] 7. The material of the brush roller can be nylon filaments or a soft material with better cleaning effect. A covering layer similar to the material of the brush roller can be attached to the inner wall of the inner shell of the drum and the inner wall of the door body. For example, a nylon filament covering layer. The nylon filament brush roller and the nylon filament covering layer are designed to be detachably connected to the drum and the door body, making installation and replacement more convenient. The relative dimensions between the brush roller and the inner shell of the drum can be tested and adjusted. Coupled with the motor speed obtained through debugging, the frequency and time of spraying the cleaning liquid, and drying by the hot air module, the optimal parameter conditions can be finally obtained for cleaning the cards, thus achieving a good cleaning effect. This application provides optimization and subsequent transformation space for the hardware and software of the cleaning degree of the cards, can clean the cards well, and has strong compatibility. By adjusting the speed, the material of the brush roller, the inner layer of the inner shell of the drum, the cost of the cleaning liquid, and the relative ratio of the brush roller and the inner shell of the drum, it can be compatible with different types of card cleaning and achieve a good cleaning effect.
